142. EGLN1 involvement in high-altitude adaptation revealed through genetic analysis of extreme constitution types defined in Ayurveda Full Text available with Trip Pro

with patients suffering from high-altitude pulmonary edema, whereas it was present at a significantly lower frequency in Pitta and nearly absent in natives of high altitude. Analysis of Human Genome Diversity Panel-Centre d'Etude du Polymorphisme Humain (HGDP-CEPH) and Indian Genome Variation Consortium panels showed that disparate genetic lineages at high altitudes share the same ancestral allele (T) of rs480902 that is overrepresented in Pitta and positively correlated with altitude globally (P < 0.001 (...) ), including in India. Thus, EGLN1 polymorphisms are associated with high-altitude adaptation, and a genotype rare in highlanders but overrepresented in a subgroup of normal lowlanders discernable by Ayurveda may confer increased risk for high-altitude pulmonary edema.

143. Shilajit: A panacea for high-altitude problems Full Text available with Trip Pro

Shilajit: A panacea for high-altitude problems High altitude problems like hypoxia, acute mountain sickness, high altitude cerebral edema, pulmonary edema, insomnia, tiredness, lethargy, lack of appetite, body pain, dementia, and depression may occur when a person or a soldier residing in a lower altitude ascends to high-altitude areas. These problems arise due to low atmospheric pressure, severe cold, high intensity of solar radiation, high wind velocity, and very high fluctuation of day (...) fatigue. Shilajit improves the ability to handle high altitudinal stresses and stimulates the immune system. Thus, Shilajit can be given as a supplement to people ascending to high-altitude areas so that it can act as a "health rejuvenator" and help to overcome high-altitude related problems.

144. High-altitude disorders: pulmonary hypertension: pulmonary vascular disease: the global perspective. (Abstract)

High-altitude disorders: pulmonary hypertension: pulmonary vascular disease: the global perspective. Globally, it is estimated that > 140 million people live at a high altitude (HA), defined as > 2,500 m (8,200 ft), and that countless others sojourn to the mountains for work, travel, and sport. The distribution of exposure to HA is worldwide, including 35 million in the Andes and > 80 million in Asia, including China and central Asia. HA stress primarily is due to the hypoxia of low atmospheric (...) pressure, but dry air, intense solar radiation, extreme cold, and exercise contribute to acute and chronic disorders. The acute disorders are acute mountain sickness (also known as soroche), HA cerebral edema, and HA pulmonary edema (HAPE). Of these, HAPE is highly correlated with acute pulmonary hypertension. The first chronic syndrome described in HA dwellers in Peru was chronic mountain sickness (Monge disease), which has a large component of relative hypoventilation and secondary erythrocytosis

). The amount of decrease in SpO(2) paralleled the increase in CCT. There was no significant decrease in visual acuity. There was a significant correlation between CCT and cerebral acute mountain sickness score when controlled for SpO(2) and age.Corneal swelling during high-altitude climbs is promoted by low SpO(2). Systemic delivery of oxygen to the anterior chamber seems to play a greater role in corneal oxygenation than previously thought. Adhering to a slower ascent profile results in less corneal edema (...) New insights into changes in corneal thickness in healthy mountaineers during a very-high-altitude climb to Mount Muztagh Ata.

at the constant risk of food insecurity. AGRA (2014) estimates that 223 million people in Africa are undernourished, most of these living in rural areas. The 2014 Global Nutrition Report adds evidence to this, identifying high rates of stunting and wasting prevailing in particular in smallholder households (IFPRI, 2014). The majority of smallholder farmers in Africa neither meet their monetary nor dietary needs through the practice of small–scale agriculture. Agricultural growth is regarded as a two–sided (...) of agricultural interventions in place across Africa (Sapa, 2009). The focus of these interventions has shifted as the understanding of the relationship between agriculture and poverty has developed (Massett et al. 2011). Early interventions focused on increasing productivity to meet a perceived lack of food. With the realisation that undernourishment persists alongside high levels of production (Reutlinger & ), structural issues came to the fore and the concept of food security was introduced

Ultimately, these cycles of awakening prohibit the apneic person from reaching deep, restful sleep. For this reason, children with untreated OSA may be inappropriately diag- nosed as having ADHD. 2 OSA differs from central sleep apnea.

156. Mitochondrial Function, Biology, and Role in Disease Full Text available with Trip Pro

The incessant energy requirements of the heart are sustained by the consumption of a mass of ATP daily that surpasses cardiac weight itself by approximately 5 to 10 fold. This perpetual demand for energy reflects the continuous contractile functioning of the heart to sustain systemic circulation and nutrient supply. This high-energy flux translates into the cardiomyocyte having a mitochondrial volume between 23% and 32% of myocellular volume. Interestingly, cardiac mitochondrial density increases from human (...) pathology is not clear cut. In this section, we give a brief overview of metabolism and perturbations and their consequences on myocardial function. ETC Biology: Energetics and ROS The final common pathway for oxidative metabolism, which generates the bulk of cardiac ATP, is the sequential passage of electrons from high (NADH or FADH 2 ) to low (molecular oxygen) redox potentials down the ETC (complexes I through IV). This stepwise electron transfer results in the active pumping of hydrogen ions out
