However, some parts of the hypothalamus can be seen on the Subdivisions of Hypothalamus external (ventral) surface of the brain. These visible parts For convenience of description, the hypothalamus may of hypothalamus are located in the interpeduncular fossa be subdivided, roughly, into a number of regions. The hypothalamus is also subdivided anteroposteriorly Region Nucleus into four regions. The preoptic region differs from the rest of the Nuclei in the Medial Zone hypothalamus in being a derivative of the telencephalon. The tuberal region also contains the aggregations, termed the hypothalamic nuclei, are as ventromedial nucleus, the dorsomedial nucleus and follows ure 9. Preoptic region Preoptic nucleus Preoptic nucleus Supraoptic region Paraventricular Supraoptic Nuclei in the Lateral Zone Suprachiasmatic Lateral Anterior The lateral zone contains a difuse collection of cells that extend through the supraoptic, tuberal, and mamillary Tuberal region Arcuate Lateral Tuberal (Infundibular) Tuberomamillary regions. The nuclei present in diferent regions of hypothalamus Aferent Connections are listed in Tables 9. The hypothalamus receives visceral aferents (including those of taste) through the spinal cord and brainstem. Connections of Hypothalamus Many of these fbres pass through a bundle called the mamillary peduncle. Other fbres pass through a bundle the hypothalamus is concerned with visceral function called the dorsal longitudinal fasciculus. Fibres from the and is, therefore, connected to other areas having a similar tegmentum of the midbrain also reach the hypothalamus function. These include the various parts of the limbic through the medial forebrain bundle. These are the anterior perforated substance, the septal nuclei, the amygdaloid complex, the hippocampus and the piriform cortex. Others relay in the thalamus (medial, dorsal, and midline nuclei) and reach the hypothalamus through periventricular fbres (so called because they travel just subjacent to the ependyma). The cingulate gyrus may infuence the hypothalamus indirectly through the hippocampal formation. Some fibres from the orbital cortex may reach the hypothalamus through the medial forebrain bundle. Centres in the brainstem receiving such fbres include the nucleus of the solitary tract, the dorsal nucleus of the vagus, the nucleus ambiguus, and the parabrachial nucleus. Fibres descending to the spinal cord end in neurons in the intermediolateral grey column. It also sends fbres to the hippocampal formation, the septal nuclei, the amygdaloid complex, and the tegmentum of the midbrain, and autonomic centres in the brainstem and spinal cord. Tese fbres pass through the same bundles that convey aferent fbres from these centres. Fibres from the mamillary nuclei also reach the subthalamic region and the tegmentum. They play a role in maintaining cortical The hypothalamus plays an important role in the control of arousal. The fibre bundles associated with hypothalamus In exercising such control, the hypothalamus acts in close along with their functions are summarized in Table 9. The main Hypothalamus functions attributed to the hypothalamus are as follows: Neurons in some hypothalamic nuclei produce bioactive Regulation of Eating and Drinking Behaviour peptides that are discharged in the neighbourhood of capillaries or, in some cases, into the cerebrospinal fuid. The hypothalamus is responsible for feelings of hunger The process of the production of such bioactive substances and of satiety. A feeding centre has been described in the by neurons (as distinct from release of neurotransmitters lateral hypothalamic nucleus and a satiety centre, in the at synapses or eferent nerve endings) is referred to as ventromedial nucleus. Regulation of Sexual Activity and Reproduction The hypothalamus controls sexual activity, both in the Control of Neurohypophysis ure 9. It also exerts an efect on gametogenesis, Vasopressin (antidiuretic hormone) and oxytocin, on ovarian and uterine cycles, and on the development of associated with the neurohypophysis, are really neuro secondary sexual characters. These efects are produced secretory products synthesized in the supraoptic and by infuencing the secretion of gonadotropic hormones by paraventricular nuclei of the hypothalamus. They join axons arising from the supraoptic The hypothalamus exerts an important infuence on the nucleus to form the supraopticohypophyseal tract. Sympathetic activity is said to be axons branch profusely and end in relation to capillaries controlled predominantly by caudal parts of the hypo around which they release their secretion. Emotional Behaviour Control of the Adenohypophysis by the Hypothalamus the hypothalamus has an important influence on emotions like fear, anger, and pleasure. Stimulation of The hypothalamus controls secretion of hormones by the lateral areas of the hypothalamus produces sensations of adenohypophysis by producing a number of releasing pleasure, while stimulation of medial areas produces pain factors. Control of Endocrine Activity The cells of the arcuate (infundibular) nucleus produce The infuence of the hypothalamus in the production of releasing factors that travel along their axons and are hormones by the pars anterior of the hypophysis cerebri released into the capillaries. These capillaries carry these and the elaboration of oxytocin and the antidiuretic factors into the pars anterior of the hypophysis cerebri hormone by the hypothalamus itself have been described through the hypothalamohypophyseal portal system. Through control of the adenohypophysis, the the pars anterior, these factors are responsible for release hypothalamus indirectly infuences the thyroid gland, the of appropriate hormones.

However, it is now known to be an endocrine Stria Medullaris Thalami (Stria Habenularis) gland of considerable significance. Pinealocytes are separated from one another by neuroglial cells that The stria medullaris thalami is a bundle of fbres lying resemble astrocytes in structure. It begins near the wall of the third ventricle is through a stalk that has two anterior pole of the thalamus and runs backwards to reach laminae: superior and inferior. Many aferents to the habenular traversed by fbres of the habenular commissure and the nuclei are from the septal nuclei and pass through the stria inferior lamina, by fbres of the posterior commissure. The pineal body is innervated by postganglionic Some fbres of the stria medullaris thalami cross in the sympathetic neurons located in the superior cervical superior (or anterior) lamina of the pineal stalk to reach sympathetic ganglia. Fibres arising in these nuclei form the habenulopineal Several neuromediators have been demonstrated in the tract. Function Posterior Commissure the pineal body produces a number of hormones The posterior commissure lies in the inferior lamina of (chemically indolamines or polypeptides). A number of small nuclei are hormones have an important regulatory influence present in relation to the commissure. These include the on many endocrine organs, including the hypophysis interstitial and dorsal nuclei of the posterior commissure, cerebri, the thyroid, the parathyroids, the adrenals, and the nucleus of Darkschewitsch, and the interstitial nucleus the gonads. Some fbres arising from these nuclei pass through hypophysis cerebri both through blood and through the the posterior commissure. Some fbres arising Some activities of the pineal body (for example, the secretion of the hormone melatonin) show a marked circadian rythm, which appears to be strongly infuenced by exposure of the animal to light. Clinical AnatomyClinical Anatomy A tumour of the pineal body can produce precocious puberty. Habenular Nuclei The habenular nuclei (medial and lateral) are situated in relation to a triangular depression in the wall of the third ventricle called the habenular trigone. The habenular nuclei of the two sides are connected by fbres that form the habenular commissure. The habenular nuclei infuence neurons concerned with various visceral and endocrine functions. The subthalamic region also contains two bundles of the part of the diencephalon that is called the ventral fbres that connect the globus pallidus to the thalamus. Associated with these bundles, there are Inferiorly, the ventral thalamus is continuous with the certain regions called the felds of Forel (H, H1, and H2) as tegmentum of the midbrain. Starting from the globus pallidus, the ansa lenticularis The main masses of grey matter that are included in winds round the ventral and posterior border of the the ventral thalamus are the reticular nucleus (previously internal capsule to reach the subthalamic region, where described as part of the dorsal thalamus) and the zona it lies ventral and medial to the subthalamic nucleus. Fibres of the fasciculus lenticularis intersect those of the internal capsule to reach the subthalamic region. Here, Reticular Nucleus they pass medially above the subthalamic nucleus and below the zona incerta. The reticular nucleus is made up of a thin layer of neurons the subthalamic fasciculus (connecting the globus covering the lateral aspect of the (dorsal) thalamus, pallidus to the subthalamic nucleus) occupies a position separated from the latter by the external medullary intermediate between the ansa lenticularis and the lamina. Inferiorly, it becomes partially continuous with and of the fasciculus lenticularis join together medial to the the zona incerta. The thalamic fasciculus passes above through it give the nucleus a reticulated appearance, and the zona incerta (feld H1 of Forel) to reach the thalamus. In this way, the nucleus receives somatic, visceral, Subthalamic Nucleus (of Luys) and auditory impulses. The main eferents of the reticular As explained above the subthalamic nucleus, which has nucleus pass back into the dorsal thalamus. They may infuence conduction through region is now grouped functionally with the basal nuclei/ the dorsal thalamus ure 9. The posteromedial group The zona incerta is a thin lamina of grey matter continuous of branches (also called thalamogeniculate arteries) with the reticular nucleus of the thalamus. The posterolateral between the subthalamic nucleus and the thalamus group (also called thalamogeniculate branches) supply ure 9. These communicating, anterior choroidal, posterior choroidal, are termed the nuclei of the prerubral feld. The anterior part of the hypothalamus is supplied by Fibre Bundles Passing Through Subthalamic central branches of the anteromedial group (arising from the anterior cerebral artery). The posterior part is supplied Region by central branches of the posteromedial group (arising In addition to its grey matter, the subthalamic region from the posterior cerebral and posterior communicating contains a number of fibre bundles ure 9.

Finally medications help dog sleep night generic rumalaya 60pills with amex, and perhaps most importantly symptoms 4 months pregnant order 60 pills rumalaya overnight delivery, the fossils discovered from Pestera cu Oase are currently the oldest known modern human fossils from Europe and exhibit a mosaic of modern and archaic anatomy (Rougier et al. The Oase discov eries have thrown fresh light upon the Romanian early modern human record, resulting in the recent direct dating of and reanalysis of the remains from Cioclovina (Harvati et al. Aurignacian/early modern human fossil sites:* 1: Bacho Kiro; 2: Cioclovina; 3: Istallosko; 4: Mladec; 5: Pestera cu Oase; 6: Pestera Muierii; 14: Hohlenstein-Stadel; 15: Honerthole; 16: Kleine Ofnet; 17: Schafstall; 18: Sirgenstein; 19: Geienkosterle; 21: Miesslingtal; 23: Goromby-Tapolca; 24: Oblazowa. Gravettian modern human fossil sites: 7: Brno-Fracouzska; 8: Dolni Vestonice; 9: Predmosti; 10: Pavlov; 11: Willendorf; 12: Krems-Wachtberg; 13: Geienkosterle; 20: Hohle Fels; 22: Grub/ Kranawetberg. Presumed early specimens, such as those from Binshof-Speyer, Hahnofersand, Vogelherd (Stetten), and Paderborn-Sande, have all been redated to the Holocene (with the last being less than 300 years old! Radiocarbon dates (Muller-Beck, 1983), as well as the numerous Aurignacian artifacts from the two strata from which the Vogelherd human remains were collected (Riek, 1934), had indicated that the remains dated to > 30 ka. Thus, all of the Vogelherd human remains were from intrusive Neolithic burials that were not detected during excavation. Although the incorrect and, until recently, accepted dates for the Vogelherd remains can be understood as the result of early and imprecise excavation, the incorrect dates for Binshof Speyer, Hahnofersand, and Paderborn-Sande (Table 5. Kelsterbach, another specimen that was also given an early date by the Frankfurt laboratory, was used by Protsch as evidence for an early presence of modern humans in Central Europe (Protsch and Semmel, 1978). This specimen has gone missing and its date cannot be verified or, more likely, falsified by new dating (Street et al. So, what is left of the early modern human fossil record in western Central Europe Unfortunately, none of the remaining candidates have been directly dated, and, even if we accept that these remains are Aurignacian, they are few and largely not diagnostic anatom ically. They, furthermore, mention fragmentary remains from Honerthohle as having a possible but uncertain association with Aurignacian artifacts. Thus, it is currently unclear what biological population was associ ated with the Aurignacian of western Central Europe. The relative lack of early modern human remains from this region is ironic given the wealth of Aurignacian archaeological discoveries that have been made in the last couple of decades, especially in the Swabian Jura (Conard, 2009; Conard et al. Additional, albeit more recent, Aurignacian flutes are known from Geienklosterle (Hahn and Munzel, 1995) and Vogelherd (Conard and Malina, 2006). Recent work at Hohle Fels documents a significant technological shift across the Middle to Upper Paleolithic boundary, indicating, perhaps, a shift in human population as well (Conard and Bolus, 2008). With the redating of the Binshof specimen to the Bronze Age (Terberger and Street, 2001), the Gravettian human fossil record of western Central Europe now comprises only two teeth from Geienklosterle and a single tooth and cranial fragment from Hohle Fels. The Geienklosterle teeth comprise a right upper decid uous molar and another deciduous molar (Haas, 1991; Hahn et al. The Hohle Fels Gravettian tooth is a right lower deciduous molar, while the cranial fragment may be from a young adult (Haas, 1991). As Street and colleagues (2006) point out, the paucity of Gravettian fossils in Germany contrasts with the number of documented Gravettian sites in the country as well as with the large Gravettian skeletal samples from Moravia. As is the case for the Aurignacian-associated remains from western Central Europe, the Gravettian remains are largely uninformative about the biology of the Gravettian peoples in this region. Pre-Gravettian Modern Human Fossils from Eastern Central Europe Although the eastern part of Central Europe has now traded places with the western part as the area with the most information about the biology of the first modern humans in the region, the record is far from perfect. The Mladec fossils have played a role in understanding modern human origins in this region for some time, but the claim of unclear association with the Aurignacian, at least for some of the human fossils, and the lack of direct dates (but see Wild et al. Questions still remain about the chronology and context of the Mladec remains as well as how to interpret their mosaic anatomy. The fragmentary remains from Svaty Prokop (Bohemia), the Velika Pecina frontal (Hrvatsko Zagorje), and the partial skel eton from Zlaty Kun (Bohemia) all succumbed to such redating (Table 5. While Zlaty Kun remains (barely) Pleistocene in age following direct dating (Svoboda et al. Churchill and Smith, 2000) have not been directly dated and have unclear or no associations with arti fact industries. In the case of the Podbaba calvarium, direct dating will never be possible since the specimen was destroyed in 1921 (Churchill and Smith, 2000). Given the lessons of Velika Pecina, Zlaty Kun, and the numerous German fossils discussed earlier, the Podbaba and Silicka Brezova remains should not be included in discussions of early modern humans in Central Europe. The molar germ of Istallos-ko lacks a direct date, but its association with the Aurignacian may be more acceptable (Tillier et al. For example, the Miesslingtal juvenile mandibular corpus remains undated but is reported to come from an Aurignacian context (Felgenhauer, 1950; Sombathy, 1950). Anatomically, Sombathy reports that it is modern human, and its dental metrics fall with the early Upper Paleolithic (Smith, 1984). Nevertheless, Tillier and colleagues (2006) contend that no features of the tooth can distinguish it from Neandertals or modern humans. More recently, Bailey and colleagues (2009) note that the tooth lacks both a hypo conulid and a midtrigonid crest, aligning it with Upper Paleolithic modern humans. The three anterior teeth from the Aurignacian Fd stratum at Vindija Cave, as noted by Smith (1984), are large and anatomically fall with both Neandertals and early modern humans. An additional Aurignacian fossil, the Vi 302 left parietal fragment, was published by Smith and colleagues (1985). This specimen articulates with the previously unprovenienced Vi 204 right parietal. These conjoined pieces exhibit moderate lambdoidal flattening combined with greater biparietal expansion than that usually seen in Neandertals. Furthermore, given chronological uncertainties and lessons learned from directly dating other supposed early modern human fossils, the Miesslingtal, Istallos-ko, and Vindija F fossils should be only tentatively placed in the pre-Gravettian modern human sample until direct dates and/or additional chronolog ical information become available. Mladec the oldest directly dated, Aurignacian-associated modern human remains from Europe come from the Moravian site of Mladec, a cave system located inside of Tresin Hill in the Czech Republic. The remains from this site, as well as possibly associated Upper Paleolithic artifacts, were not the result of habitation but rather were likely dropped through a vertical chimney (Svoboda, 2000, 2006). These remains include the two, possibly female, crania Mladec 1 and 2 as well as the Mladec 8 maxilla, Mladec 3 child, and several postcranial pieces. Although many artifacts and bones were lost during and initially after the original discovery of this chamber, the possibly male crania, Mladec 5 and 6 and other elements, as well as many artifacts, were recovered and curated (Frayer et al. Only the Szombathy col lections (at the Natural History Museum in Vienna), four hand bones and four cranial fragments from the private collection of Jan Knies, and Mladec 5 remain, the last having survived the Mikulov fire. The Mladec remains, recognized as potentially early and associated with the Aurignacian, gained attention by the late 1970s. While Stringer (1974, 1978) viewed them as fully modern and lacking any Neandertal aspects, others (Frayer, 1986; Smith, 1984; Wolpoff, 1999) saw otherwise, especially in specific details of anatomy. This gulf in interpretation of the evolu tionary significance of the Mladec fossils persists with Brauer (Brauer and Broeg, 1998; Brauer et al. Confounding interpretations of the Mladec fossils has been the difficulties in under standing their provenience, chronology, and archaeological associations (Frayer et al. Direct dating of Mladec 1, 2, 8, 9 and 25c (proximal ulna), all from Chamber D, has helped tighten up the chronology for the Main Cave speci mens, but the lack of direct dates for the only surviving Quarry specimen, Mladec 5, 15 does not help clarify the question of contemporaneity between the two samples. There is, however, an extensive bone tool sample made up of numerous bone points (especially massive based/Mladec points), awls, worked animal metacarpals (some with drilled holes), carnivore and beaver teeth with bored holes in the roots, and other items (Oliva, 2006). As noted by Oliva (2006), most of these bone artifacts derive from the Main Cave, but some were recovered in the Quarry Cave. This indicates the Quarry and Main Caves are roughly contemporaneous (see also Frayer et al. Thus they are not conclusive evidence of a Neandertal contribution to the Mladec people. Both femora exhibit the proximal-lateral femoral flange that tends to be found in European Neandertals and early moderns but not in the Near Eastern Neandertals and early moderns (Cartmill and Smith, 2009). This might be evidence of European continuity, but the polarity of this trait is not clear. One of the lost specimens, a proximal femur (Mladec 78), shows strong anterior-posterior curvature, a trait common in Neandertals but not uncommon in early moderns. The craniodental remains have traditionally been considered as showing the best evidence of continuity (Churchill and Smith, 2000; Frayer, 1986; Jelinek, 1969; Smith, 1982). In their recent analysis of the Mladec males, Frayer and colleagues (2006) note that these are not Neandertals but that a hypothesis of equal ancestry from Neandertals on one hand and the Skhul-Qafzeh group on the other cannot be rejected (see also Wolpoff et al. Frayer and colleagues (2006) focus on overall shape of the vault (particularly the low vault height), parietal bone shape, the presence of occipital bunning and lambdoidal flattening, pro nounced browridges, a projecting upper face (but with a pattern of flatness different from Neandertals), and an inferior bulging of the occipitomastoid region, resulting in relatively non-projecting mastoid processes, as particularly demonstrating continuity with European Neandertals. They also note the large tooth size, especially the canines of Mladec 8 and 9, and the shoveling of the latter as further indicators. The possible female crania (Mladec 1 and 2) are described as showing less evidence of continuity but still exhibiting occipital bunning and lambdoidal flattening (only present in Mladec 1), and the same mastoid occipitomastoid area morphology as the males (Wolpoff et al. Not everyone accepts the Mladec morphology as indicative of a Neandertal contribution to early modern Europeans. In a recent investigation of overall cranial form, Weber and colleagues (2006) compare the Mladec 1, 5, and 6 neurocrania to a sample of anatomically modern humans and archaic humans, the latter consisting of Neandertals and earlier mem bers of the genus Homo. They note more overlap in the morphology of this latter region in their analyses and conclude that overall posterior cranial form does not distinctly separate Neandertals and anatomically modern humans. Earlier Brauer and Broeg (1998) argued that analysis of discrete cranial features does not show evidence of continuity, nor did a metric analysis of the fronto-facial region (Brauer et al. Frayer and colleagues (2006) dispute the discrete trait study, but the other two studies underscore what earlier multivariate metric studies have generally found: the Mladec crania have a basically modern form. One feature that figures prominently in discussions of Mladec and the issue of continuity is occipital bunning. Often it is suggested that the bunning in Neandertals and that in early modern Europeans was not homologous. It has long been recognized that the buns in early moderns were generally not as laterally extended as in Neandertals and were located relatively more inferiorly in the former (Smith, 1982; Cartmill and Smith, 2009). However two recent studies of bunning in Neandertals and early modern Europeans conclude that the structures are homologous (Gunz and Harvati, 2007, 2011; contra Nowaczewska and Kuzminski, 2009). The Harvati and Gunz studies conclude that the bunning morphology is a part of the integrated form of the cranium and should not be used as an independent trait to argue for European continuity. Of course, most everything in the cranium is integrated to some extent at least, but the fact is that European Neandertals and early moderns commonly exhibit a character state where the structure of a bun is specifically definable morphologically (Cartmill and Smith, 2009). In Neandertals, this is a horizontally elongated, elliptical depression just above the superior nuchal line, normally identified by a grainy appearance of the external table in the depression. Frayer and colleagues (2006) maintain that Mladec 6 is the only early modern European that has a Neandertal-like fossa, albeit weakly developed. Mladec 5 has a small, circular depression with similar surface characteristics located at the midline just above the superior nuchal line. There has been considerable controversy concerning the rela tionship of the Neandertal suprainiac fossa to a variety of similar manifestations in early modern Europeans, including the two Mladec variants (Ahern, 2006a; Balzeau and Rougier, 2010; Cartmill and Smith, 2009; Nowaczewska, 2011). It seems clear that some of the vari ants recognized as possible suprainiac fossae in the past represent something not homolo gous to the Neandertal feature, a fact first noted by Caspari (1991). The most convincing study is by Balzeau and Rougier (2010), who demonstrate a structural difference in the fossa of Neandertals and those of modern humans. If confirmed this would essentially remove the suprainiac fossa from the debate on continuity as the depression would be clearly non-homologous. One issue that needs to be addressed is that 182 the Origins of Modern Humans (a) (b) (c) (d) Supralniac fossa Figure 5. Mladec 6 (a) and Mladec 5 (b) in posterior view with a diagram, below, showing the (c) Neandertal-pattern and the (d) Upper Paleolithic modern-pattern suprainiac fossae. Balzeau and Rougier do not include any early Upper Paleolithic Europeans in their study. The fact that the structure might represent a functional adaptation (Caspari, 1991; Nowaczewska, 2011) would not necessarily remove the possibility of homology. Pestera cu Oase the site of Pestera cu Oase, located in southwestern Romania, was discovered during spele ological exploration in 2002. A human mandible, Oase 1, was discovered at that time lying on the surface (Trinkaus et al. Further exploration between 2003 and 2005 yielded most of a human cranium, Oase 2.

A growing body of evidence has supported both hypotheses and will be reviewed here. Altered glycolytic enzymes in cancer cells In cancer cells, the activities or expression levels of many enzymes participating in glucose metabolism are altered, those involved in glycolysis in particular. The glycolysis commonly refers to the reactions that covert glucose into pyruvate or lactate ure 1). Usually, one or more isoforms of glycolytic enzymes have altered expression patterns or activities in cancer cells, which was previously reviewed (Herling et al. It is also differentially regulated at the post-translational level in cancer cells as compared with normal cells. Five aspartate and five glutamate residues were found to be specifically methylated in pancreatic cancer. Several serine and threonine residues were found to be specifically phosphorylated in leukemia, cervix, and lung cancers. Glucose metabolic pathways switched by oncogenes and tumor suppressors It has been long proposed that the altered expression or enzyme activities of glycolytic enzymes are regulated by oncogenes and tumor suppressor genes. Therefore, activation of oncogenes and loss of tumor suppressors are believed to underlie the metabolic switch in cancer cells. Another oncogene, K-Ras, can alter glucose metabolism so as to provide tumor cells with a selective advantage. Interestingly, in these cells mitochondrial functions and oxidative phosphorylation are not compromised, which allows increased survival rate of the K-Ras mutant cells during glucose deprivation (Annibaldi and Widmann, 2010). A potential advantage, as a result of Warburg effect, is high production of lactic acid due to enhanced glycolysis. Positive correlation between lactate serum levels and tumor burden in cancer patients has been well documented, implicating a role of acidic microenvironment in promoting tumor growth and development (McCarty and Whitaker, 2011). First, accumulated evidence has suggested that acidic environment amplifies the capacity of invasion and metastasis of cancer cells. For instance, acid pretreatment of tumor cells enhance their ability to form metastases in tumor-transplanted mice (Rofstad et al. Consistently, it has been shown that increasing tumor pH via bicarbonate therapy significantly reduces the number and the size of metastases in a mouse model of breast cancer (Robey et al. Second, the extracellular pH of solid tumors is significantly more acidic than that of normal tissues, thus impairing the uptake of weakly basic chemotherapeutic drugs (Raghunand et al. Several anticancer drugs such as doxorubicin, mitoxantrone and vincristine are weak bases that are protonated in slightly acid tumor microenvironments. The protonated forms of the drugs cannot easily diffuse across the plasma membrane and therefore their cellular uptake is suppressed. It has been demonstrated that the addition of sodium bicarbonate in the drinking water enhanced the anti-tumor effect of doxorubicin on xenotransplanted tumors presumably by enhancing the intracellular drug delivery through raising the pH of the extracellular milieu in mice (Raghunand et al. The reverse situation was also demonstrated in another study showing that glucose administration to mice led to a lower efficacy of doxorubicin on tumors presumably due to a decrease in the extracellular pH (Gerweck et al. Glucose Metabolism and Cancer 295 Third, acidic microenvironment inhibits anti-tumor immune response. Activated lymphocytes themselves use glycolysis, which relies on the efficient secretion of lactic acid. Export of lactic acid from lymphocytes depends on a gradient between intracellular and extracellular lactic acid concentration. High extracelullar acidity would diminish this gradient and block the secretion of lactic acid from lymphocytes. The accumulation of intracellular lactic acid eventually disturbs the glycolysis process hence affecting the activity of lymphocytes. Acidification similarly inhibits the activity of other immune cells such as dendritic cells. Coupled biological and metabolic processes and the logic of a mammalian metabolic cycle Glycolytic enzymes have multiple cellular functions. Conceivably, the participation of these glycolytic enzymes in such a cell cycle event would subject cell cycle regulation to altered glucose metabolism in cancer cells, providing yet another mechanistic explanation of cancer growth and development.

This tends to create a misperception of the origins and impacts of the food being consumed, thus hampering consumer awareness. Consumers in the lower economic classes are even less aware of the collateral effects of cheap and low quality food on weight, for instance (Cole et al. When it comes to land degradation, agrochemical and biotechnology industries are partly responsible (see also Chapter 4, Section 4. Moreover, greater complications come from the fact that degradation induced by the agrochemical industry or other market forces can apply to different levels of biodiversity: the level of landscape and field (ecosystem diversity), the level of specific biodiversity or genetic diversity. Ecosystem diversity is strongly affected by open-field monocultures based on mechanization and heavy chemical inputs. For instance, while using glyphosate in no-tillage agriculture is efficient against land degradation (see Section 1. Regarding fertilizers, Reganold and Glover (2016) assert that soils in many regions across Sub-Saharan Africa are depleted to the extent that simply adding fertilizer will not improve soil health and may even make it worse (see also Box 2. The liberalization of trade, in any of the cases, needs a high-level decision through international agreements. This misinformation is further accentuated by the growing disconnect between food production, processing and consumption (Clapp, 2014; Henders & Ostwald, 2014). This section begins with a summary of the concepts brought out in successive Earth Summits and the logic underlying international negotiations. Understanding what appears as political inertia (Brand & Gorg, 2013) is central to shifting away from policies that aim to slow down degradation to implementing policies that seek to reverse it. Another aspect explored in this section is the delay between scientific alerts and political decision. A fuzzy concept contains more ideology than reality, generating multiple understandings, which can lead to damaging decisions. The conference was meant to raise global environmental concern and initiate a global eco-management strategy; and in practice, it catalysed an inflexion in environmental policies (White, 1982). The discussions in the Summit mostly revolved around development versus environment (Caldwell, 1972; Robinson, 1972; Rowland, 1973). The problems facing us today were already flagged in the preliminary debates and reports for Stockholm Conference (Hardin, 1968; Meadows et al. In Stockholm, some developing countries strongly opposed environmental norms and taxes on the grounds that they could hamper socio-economic development (Robinson, 1972). The necessities of achieving development was a priority to reduce poverty and reach Western standards of living (Castro, 1972) with a twofold ideological basis: 1. Hence, the idea that environmental concerns was a way for industrialized countries to impose restrictions on the development of other countries was deeply anchored (Head, 1977; Kennet, 1972; Kiss & Sicault, 1972). Genetic diversity did not become the financial manna expected and the collective intellectual property of indigenous and local communities has not yet been clearly conceptualized (Gorg & Brand, 2006) nor defined in law. The reluctance of corporations to invest in and pay for indigenous or local knowledge about biodiversity is partially due to the complexity of negotiating rights to access and to benefit-sharing (Rosendal, 2011). Other developing countries (G77) disagreed with this orientation (Visentini & da Silva, 2010). This last point strongly contrasts with the Stockholm principles, which asserted that sovereign rights came along with sovereign responsibilities. Another contrasting approach is about human demography: while Stockholm Declaration acknowledged the fact that demography was an environmental problem (see subsection 2. The focus on the human dimensions of sustainable development push us to think about different ways of conceptualizing socio-ecological relationship. As this chapter will further explore, we propose ecological solidarity (see Section 2. The next section revisits the demographic issue through the lens of environmental impact. If fertility declines from what it is today, but remains half a child above the replacement level, human population will grow 120% and reach 16. This would lead, not only to an unsustainable demand in food and energy, but also to irreversibly transformed land through urban sprawl encroaching on croplands, thus threatening food security (Barbero-Sierra et al. For almost half a century, the growth of human populations has been blamed directly for environmental degradation (Diamond, 2005; Ehrlich, 1968; Hardin, 1968; Meyer & Turner, 1992; Robinson & Srinivasan, 1997). This led to years of discussion about the need to reduce population growth rates where they are high, often in developing countries. Moreover, protected areas in poor countries tend to attract population for an easier access to natural resources, in the absence of better options (Joppa et al. Many scholars objected to the focus on the number of people in developing countries. More attention is now given to how much each person consumes and how the Earth is used to support each person, especially in the context of growing meat consumption (Alexandratos & Bruinsma, 2012; Bailey et al. If consumption per capita is important for degradation, then limiting consumption per person is also an appropriate goal (Ehrlich & Ehrlich, 2009; Ehrlich & Holdren, 2011). Both issues are equally complex as developing and emerging countries are striving to achieve Western standards of living and many developed countries are reluctant to change their way of life. The declaration of Stockholm acknowledged the environmental problem caused by overpopulation in its 16th statement: countries should control their demography without affecting human basic rights. The Stockholm Summit was followed by the World Conference on Population in Bucharest in 1974, where conflict led to the absence of a strong resolution (George, 1975). Soon after, the population problem was principally deemed a social and/or educational problem, excluding it from environmental discussions. A major step in this direction was the International Conference on Population and Development, held in Cairo in 1994. Its conclusion was that demography was a matter of education and empowerment of women, to be solved by international aid (Ashford, 2001; McIntosh & Finkle, 1995; Roseman & Reichenbach, 2010). A solution, accordingly, could be to establish a universal retirement system, where pensions would be guaranteed even in case of political instability. Where appropriate, institutional changes must be implemented so that old-age security does not entirely depend on input from family members. Demographic issue is even more of a delicate matter in those countries where having many children is an element of social prestige for men, especially, but not only, in polygamist countries (Fargues, 1994; Goldstone, 2010). Such a system of value cannot be changed by policies alone, but should be accompanied, where appropriate, by awareness-raising of the environmental impacts. Demographic issues also apply to developed countries, especially where extensive welfare policies exist. Even after the demographic transition, the population does not diminish, partly because immigration from overpopulated or conflict-ridden countries compensates for the birth deficit. The ghost of an unbalanced rate between retired and active workers also looms on these policies (Murray, 2008; Van De Kaa, 2006) (see Figure 2. Perhaps the key problem lies in the conception that birth limitation is invariably a violation of human rights. This perception is somewhat one-sided insofar as there is a distinction between controlling natality and not encouraging it. Family allowances are frequently proportionate to the number of children (Kalwij, 2010), hence discouraging natality would consist in limiting allowances to one or two children (Cochet, 2009). The Alliance for a Green Revolution in Africa programme, as discussed below (Box 2. The current President of the African Development Bank declared, in 2016, that agriculture is a business and highlighted the importance of the Alliance for a Green Revolution in Africa for African food security (see. The programme sets out to: encourage private investors in the agricultural sector; adopt hybrid varieties. This view was expressed in a programmatic paper signed by two members of the Rockefeller Foundation and by the President of the African Bank of Development (Toenniessen et al. While the objective of an African Green Revolution is to ensure cereal self-sufficiency by 2050 (van Ittersum et al. Most of the literature dealing with ex-post evaluation in several African countries (Ghana, Uganda, Tanzania and others) insist on the very context-specific successes or failures of this trend towards modernization and market-based policy (Dawson et al. One of the inhibiting factors is the strongly anchored traditional seed exchange system, reluctant to adopt hybrid varieties (Louwaars & de Boef, 2012). A comparison between Asian and African Green Revolution shows that in the case of the former, the countries (especially India and Indonesia) were strongly supported and oriented by States, whereas Green Revolution in Africa relies more on markets for internal and external demand (Fischer, 2016). The same author asserts that African Green Revolution, contrarily to the Asian one, is not scale-neutral. On the other hand, the Alliance for a Green Revolution in Africa programme has been criticized by both scientists and international organizations. This assessment involved 400 researchers and dozens of national delegates (including those from Sub-Saharan Africa), who strongly recommended the adoption of agroecology as a sustainable practice. The Alliance for a Green Revolution in Africa was also criticized by the special rapporteur on the Right to Food, in a statement submitted in 2009 to the Human Rights Council of the Office of the United Nations High Commissioner for Human Rights (Schutter, 2009). The conclusions of the Report on the Right to Food (Schutter, 2010) were identical. Indeed, a recent review showed that the cost of externalities provoked by pesticides is greater than the benefits of an increase in production (Bourguet & Guillemaud, 2016; Marcus & Simon, 2015; van Lexmond et al. Land investment by multinational corporations can make the lives of small-scale farmers precarious because they are marginalized in the wider agricultural economy (Martiniello, 2013; Matondi et al. The main waste occurs in the phase of post-harvest handling and storage (35%), processing (12%) and distribution (12%). When the estimation is based on the number of calories, food loss in Sub-Saharan Africa goes up to 39%, while the main losses occur in the post-harvest handling phase (see Figure 2. Almost inconceivably, for the first time in human history, geophysical, climatic and biological changes are outrunning the time of political decision-making and are reaching the point of no return, as recently confirmed by an opinion paper signed by more than 15000 scientists (Ripple et al. Markets and economic competition still govern international relations, which in turn, often ignore the impacts of land degradation, overexploitation of natural assets and climate change on quality of life and human well being (Chan et al. Some of the principles or issues that could have been considered as efficient instruments to build a common ground for negotiation were not adopted because of this tension. Both of these were coined in the 1930s by Italian philosopher and dissident Antonio Gramsci. That is, a hegemonic class rules by incorporating some of the interests of subordinate classes. New policy instruments could be used to facilitate international negotiations by fostering transnational and agreements. Some studies have been made to explore the possibilities to extend it as a fundamental principle in environmental law and as a powerful tool for policymakers.
