Genetic variability and geographic differentiation among three species of Triatomine bugs (Himiptera- Reduviidae)
(Am. J. Trop Med. Hyg., 1997)
Abstract.
Three species of triatomine bugs, Triatoma sordida, T. guasayana, and T. patagonica, were examined by cytogenetic (C-banded karyotypes and male meiotic process) and isoenzymatic studies. These three species, ...
Low probability of transmission of Trypanosoma cruzi to humans by domiciliary Triatoma sordida in Bolivia
(Transactions of the Royal Society of Tropical Medicine and Hygiene, 1997)
Abstract
The role of Triatoma sordida in the domestic transmission of Trypanosoma cruzi was assessed in 7 rural localities in Velasco Province, Department of Santa Cruz, Bolivia. Tri. sordida, the only triatomine species ...
Biosystematics of old world triatominae
(Acta Tropica, 1997)
Abstract.
Morphometric analysis of Old World species of Linshcosteus and Triatoma showed the two
genera to be well separated. However, although the analysis showed clear distinction between
the five species of Linshcosteus, ...
Ventilation and hypoxic ventilatory response of Tibetan and Aymara high altitude natives
(American Journal Physical Anthropology, 1997)
ABSTRACT.
Newcomers acclimatizing to high altitude and adult male
Tibetan high altitude natives have increased ventilation relative to sea level
natives at sea level. However, Andean and Rocky Mountain high altitude
natives ...
Differential effects of ventilatory stimulation by sex hormones and almitrine on hypoxic erythrocytosis
(Pflugers Arch-Eur J Physiol, 1997)
Abstract.
In the absence of pulmonary disease, hypoventilation is considered to be the primary cause of
Chronic Mountain Sickness, and there is some reason to
believe that chronic administration of respiratory analeptics ...
Isozymic and metric variation in the Lutzomyia longipalpis complex
(Medical and Veterinary Entomology, 1997)
Abstract. Male Lutzomyia longipalpis of two types from Bolivia were compared using isozyme electrophoresis and wing morphometry. One sample (ex Chiflonkaka Cave, alt. 2800 m at Toro Toro, Charcas Province, Potosi Department) ...
Influence of gender and endogenous sex steroids on catecholaminergic structures involved in physiological adaptation to hypoxia
(Pflugers Arch-Eur J Physiol, 1997)
Abstract.
Mechanisms underlying sex-related differences in adaptation to high altitude were investigated by
assessing the turnover of dopamine and noradrenaline in
structures of the chemoafferent pathway, i.e. carotid
body ...
Fluid regulatory hormone response to exercise after coca-induced body fluid shifts
(American Physiological Society, 1997)
To determine the effect of coca chewing on heart rate
(HR), mean arterial blood pressure (MAP), and plasma
volume and their relationship with the hormones regulating
cardiovascular and body fluid homeostasis, 16 male ...
Coca y esfuerzo físico
(Instituto Boliviano de Biología de Altura, 1997)
En la “Crónica del Perú” Pedro Cieza de León da cuenta de que al inquirir a algunos indios por qué mascaban coca, ellos respondieron que al hacerlo “sienten poca hambre y se hallan en gran vigor y fuerza”. Cuatrocientos ...
