Cerebral blood flow, brain metabolism and CSF acid-base balance in highlanders
([s.n.], 1977)SUMMARY. Cerebral blood flow (Qc), local arterio-venous oxygen difference (0₂ AVD); and pH, O₂ and CO₂ partial pressures in arterial and jugular blood and in lumbar and cisternal cerebrospinal fluids (CSF) were measured ... -
Cerebral glucose metabolism and cerebral blood flow in high-altitude residents
(Journal of Applied Physiology, 1974)The present study was performed to evaluate the hypothesis that an increased H+ production by the brain from lactic acid formation during hypoxia a role in the lowering of the bicarbonate concentration. Twenty –three ... -
Células endoteliales y trombosis en la altura
(Revista Médica, 2005)RESUMEN Es bastante conocido que la hipoxia crónica produce reacciones tanto Biológicas como Fisiológicas. En estudios sobre la fisiología de la coagulación se han observado actividades diferentes sobre este mecanismo en ... -
Chagas disease vector control in Central America
(Parasitology Today, 1997)As the Southern Cone Initiative proceeds steadily towards eradication of Triatoma infestans, there is increasing interest in applying similar approaches to control Chagas disease vectors in Mexico, Central America and ... -
Chagas serology and its problems
(Ann. Soc. Belge Med. Trop., 1985)Summary. We performed a comparative study (263 sera) of four serological techniques for the diagnosis of Chagas' disease (IFT, CFT, ELISA, IEP). The concordance of the four techniques was 92.8 per cent, and we obtained ... -
Change in body water distribution index in infants who become stunted between 4 and 18 months of age
(European Journal of Clinical Nutrition, 2003-08)Objective. To evaluate body composition changes using bioelectrical impedance analysis and skinfold thickness measurements in infants from tropical areas who become stunted between 4–18 months of age. Design and measurements: ... -
Changes in blood gas transport of altitude native soccer players near sea-level and sea-level native soccer players at altitude (ISA3600)
(Br J Sports Med, 2013-09-03)Abstract. Objectives The optimal strategy for soccer teams playing at altitude is not known, that is, ‘fly-in, fly-out’ versus short-term acclimatisation. Here, we document changes in blood gas and vascular volumes of ... -
Characterization of T cell clones from Chagasic patients : predominance of CD8 surface phenotype in clones from patients with pathology
(Mem. Inst. Oswaldo Cruz, 1995)ABSTRACT. Human Chagas' disease, caused by the protozoan Trypanosoma cruzi, is associated with pathological processes whose mechanisms are not known. To address this question, T cell lines were developed from chronic ... -
Chemoreflex ventilatory response to CO₂ in man at low and high altitudes
(Respiration Physiology, 1972)Abstract. On man, a peripheral chemoreflex ventilatory response curve was obtained by measuring ventilatory reactions to the transient inhalation of a CO₂-rich mixture. Experiments have been performed. 1) on lowlanders ... -

Chronic mountain sickness and cor pulmonale La Paz-Bolivia (3,600-4,100 m)
(Life on the Qinghai Tibetan plateau, 2007)Summary. Among the majority of inhabitants of La Paz-Bolivia (3,200-4,100 m.), the mild elevation seen in pulmonary artery pressure (PAP) has no clinical significance and is reversible on descent to lower altitude or with ... -
Chronic mountain sickness, optimal hemoglobin and heart disease
(High Altitude Medicine & Biology, 2006-06)Abstract. For the male inhabitants of La Paz, Bolivia (3200–4100 m), and other high altitude regions in America and Asia, chronic mountain sickness (CMS) is a major health problem. Since CMS was first described by Carlos ... -
Ciclo estral y estudio gonádico-genital del ratón albino en la altura
(Instituto Boliviano de Biología de Altura, 1983)Resumen. A mediados del siglo XIX, fue medido el diámetro de los eritrocitos (1) en varias enfermedades, la importancia y la variación en el tamaño y el contenido de hemoglobina de estas células comenzaron a ser apreciadas. Se ... -
Circulación pulmonar en grandes alturas
(Master, 1988)La circulación general lleva a todos los tejidos los nutrientes necesarios para la mantención de la vida, en cambio el sistema arterial pulmonar está destinado a jugar un papel importante en el llamado "intercambio gaseoso", ... -

Circulating proteins and iron status in blood as indicators of the mutritional status of 10- to 12-year-old Bolivian boys
(Int. J. Sports Med., 1994)Abstract. The purpose of the present study was to evaluate the nutritional status of children based on anthropometric measurements, biochemical indicators of protein energy malnutrition as well as hematological variables. ... -
Circulation and behaviour of two major clones of Trypanosoma cruzi in Bolivian cycles
(Mem. Inst. Oswaldo Cruz, 1996-11)On the basis of isoenzyme studies and population genetic interpretation (Tibayrenc et al. Proc. Nat. Acad. Sci. USA, 83 : 115-119, 1986), we have previously designed a molecular identification tool of two major clones of ... -
La circulation cutanée au cours de l'adaptation à l'altitude
