Morphometric differentiation between two geographic populations of Triatoma infestans in Uruguay
(Research and Reviews in Parasitology, 1995)ABSTRACT. Metric characters have never been applied in quantitative studies on Triatoma infestans, the main vector of Chagas disease in the seven southernmost countries of Latin America. A first study was carried out in ... -
Morphometrics of domestic Panstrongylus rufotuberculatus in Bolivia
(Annals of Tropical Medicine and Parasitology, 1998)The trend to domesticity in Triatominae may represent a transitionary phase towards increasing vectorial importance in the transmission of Chagas disease to humans, and requires sustained entomological surveillance. Although ... -
Morphometrie alaire et caracterisation specifique des phlebotomes
(Parasitología, 1991)Abstract. We study the information included in sandfly wings in order to test this organ as a source for the specific discrimination. The cartesian coordinates of the vein intersections are collected using a microscope ... -

mtDNA and y-chromosome diversity in aymaras and quechuas from Bolivia : different stories and special genetic traits of the andean altiplano populations
(American Journal of Physical Anthroplogy, 2011-04-05)Abstract. Two Bolivian samples belonging to the two main Andean linguistic groups (Aymaras and Quechuas) were studied for mtDNA and Y-chromosome uniparental markers to evaluate sex-specific differences and give new ... -
Muscle tissue adaptations of high-altitude natives to training in chronic hypoxia or acute normoxia
(American Physiological Society, 1996)Abstract. Twenty healthy high-altitude natives, residents of La Paz, Bolivia (3,600 m), participated in 6 wk of endurance exercise training on bicycle ergometers, 5 times/wk, 30 min/session, as previously described in ... -
NADH-linked mitochondrial respiration in the developing mouse brain is sex-, age- and tissue-dependent
(Respiratory Physiology & Neurobiology, 2019)Abstract. Mitochondria play a major role in the brain. Apart from energy production, mitochondria regulate key factors in the activation of cell signaling pathways such as survival, proliferation, and differentiation. ... -
Nasal polyp associated with mucocutaneous leishmaniasis. Report of two cases
(Eur J Dermatol, 1994)Mucocutaneous leishmaniosis (MCL) can manifest in different forms and affects skin as well as mucosae. Nasal polyps are rare. We report the cases of two male patients with nasal polyps. One polyps. One of them with cutaneous ... -
Natural populations of Trypanosoma cruzi, the agent of Chagas disease, have a complex multiclonal structure
(Proc. Natl. Acad. Sci., 1986)ABSTRACT. We have studied 15 gene loci coding for enzymes in l2l Trypanosoma cruzi stocks from a wide geographic rangFfrom the United States and Mexico to Chile and southern Brazil . T. cruei is diploid but reproduction ... -
Neonatal oxygenation, pulmonary hypertension, and evolutionary adaptation to high altitutde (2013 Grover Conference series)
(Pulm Circ, 2015-03)Abstract. Andeans and Tibetans have less altitude reduction in birth weight than do shorter-resident groups, but only Tibetans are protected from pulmonary hypertension and chronic mountain sickness (CMS). We hypothesized ... -
Neurocirugía a 3600 m. sobre el nivel del mar
(Instituto Boliviano de Biología de Altura, 1979)Desde la suposición de Paul Bert, de que “el aire enrarecido de las alturas debía producir, como mecanismo compensatorio de adaptación un aumento del número de hematíes” numerosos investigadores han reportado y comprobado ... -
New aporphine alkaloids from Guatteria foliosa
(Journal of Natural Products, 1994)Abstract. Four new, alkaloids were obtained from Guatteria foliosa, namely, the noraporphines (--)-3-methoxyputerine [1] and (+)-norguattevaline [2], the more highly oxidized (+)-3-methoxyguattescidine [3], and the ... -
New data demonstrates that relationship of salivary to serum progesterone in Bolivian women is comparable to that in other populations
(36th Annual Meeting Minnesota, 2011-04-13)Abstract. Salivary progesterone (P) concentration is widely used in field studies as a relatively easy-to-measure proxy for serum P. Chatterton et al. [Fertility & Sterility 86:723 (2006)] compared sample means of ... -
New electrophoretic evidence of genetic variation and diploidy in Trypanosoma cruzi, the causative agent of Chagas' disease
(Genética, 1985)Abstract. By changing clcctrophoretic conditions additional genetic variability was observed in both previously and newly analysed enzymatic systemes in Trypanosoma cruzi . Inferences the quaternary structure of enzymes ... -
