Previous studies of the erythropoietic response to hypoxia in high-altitude natives suggest that the hematocrit and hemoglobin values in Himalayan natives (Sherpas) are lower than expected for the altitude, perhaps because of a genetic adaptation. However, differences in sampling techniques and

A histological study of the pulmonary vasculature in a young male high-altitude Aymara Indian revealed four aspects of interest. There was muscularization of the terminal portion of the pulmonary arterial tree to involve pulmonary arterioles as small as 15 microns in diameter, thus forming a basis

BACKGROUND Nodules of cells showing a striking histological similarity to those of arachnoid villi have previously been found closely adjacent to pulmonary venules in several diseases associated with alveolar hypoxia or pulmonary oedema including mitral stenosis, plexogenic pulmonary arteriopathy,

Eutrophication of surface waters and hypoxia in bottom waters has been increasing in many coastal areas, leading to very large depletions of marine life in the affected regions. These areas of high surface productivity and low bottom-water oxygen concentration are caused by increasing runoff of

OBJECTIVE To describe the clinical spectrum and factors associated with poor short-term outcomes in children with interstitial lung disease (ILD). METHODS Retrospective chart review METHODS Pediatric Chest Clinic of a tertiary care hospital METHODS We retrieved information regarding clinical course

BACKGROUND The etiology of patients presenting with pulmonary-renal syndrome (PRS) to Intensive Care Units (ICUs) in India is not previously reported. OBJECTIVE The aim was to describe the prevalence, etiology, clinical manifestations, and outcomes of PRS in an Indian ICU and identify variables that

BACKGROUND Hydropneumothorax is an abnormal presence of air and fluid in the pleural space. Even though the knowledge of hydro-pneumothorax dates back to the days of ancient Greece, not many national or international literatures are documented. OBJECTIVE To study clinical presentation, etiological

BACKGROUND Hypoxia inducible factor-1 alpha (HIF-1α) is the key regulator of cellular responses to hypoxia and plays a central role in tumour growth. Presence of Single nucleotide polymorphisms (SNPs) in the critical regulatory domains of HIF-1α may result in the overexpression of the protein and

With an aim to study the mechanism of adaptation to acute hypoxic periods by hypoxia-tolerant catfish, Clarias batrachus, the mass-specific metabolic rate (VO2) along with its hematological parameters, metabolic response and antioxidant enzyme activities were studied. During progressive hypoxia, C.

OBJECTIVE The 2009 pandemic influenza A (H1N1) has taken its toll across most parts of India. We aimed to study its epidemiology, clinical characteristics and outcomes from an Indian multidisciplinary intensive care unit (ICU). METHODS All patients admitted to our ICU with a flu-like illness and who

A study was made of the qualitative histological features of the small pulmonary arterial vessels of 25 adult citizens of La Paz, Bolivia (altitude 3600 m) coming to necropsy. Abnormalities found included muscularization of pulmonary arterioles, the development of longitudinal muscle in the intima

OBJECTIVE To study the clinical profile of the cases of esophageal atresia (EA) and/or tracheoesophageal fistula (TEF) and various factors affecting the surgical and early postoperative management and their outcome. METHODS A prospective analysis of 127 cases of EA from February 2004 to May 2006 was

BACKGROUND In developing countries, facilities for measuring arterial oxygen saturation are not available in most settings, which make it difficult for health providers to detect hypoxemia in children with acute respiratory tract infection (ARI). Most health providers rely on symptoms and signs to

Hypoxia is an important environmental stressor that leads to rapid adaptive changes in metabolic organization. However, the molecular mechanisms of hypoxia tolerance in fish remain largely unknown. The present work was focused on understanding the molecular mechanisms and signaling pathways that may
