Consideraciones sobre la desnutrición en Centro América, con especial referencia a Costa Rica
El presente trabajo analiza ciertos conceptos referentes a la situación nutricional de Costa Rica y con menos énfasis del resto de Centro América, con base en la información disponible. Se ha tratado de describir los ...
Skeletal muscle degeneration and regeneration after injection of bothropstoxin-II, a phospholipase A2 isolated from the venom of the snake Bothrops jararacussu
A myotoxic phospholipase A2, named bothropstoxin II (BthTX-II), was isolated from the venom of the South American snake Bothrops jararacussu and the pathogenesis of myonecrosis induced by this toxin was studied in mice. ...
Hallazgos fenotípicos por imágenes con Tomografía Dental Volumétrica (TDV) en amelogénesis imperfecta
Use of Dental Volumetric Tomography for Dental Phenotyping In Amelogenesis Imperfecta
Amelogénesis imperfecta (AI) se describe como un conjunto de defectos mendelianos en la biomineralización del esmalte dental, los cuales son severos en la mayoría de los casos al presentar anormalidades tales como un grosor ...
Menopause, A Universal Female Experience: Lessons from Mexico and Central America
(Current Women’s Health Reviews 4(1), 3-8, 2008)
In Mexico and Central America, women typically experience menopause up to 10 years earlier than their U.S. counterparts. This may be due in part to numerous pregnancies, long periods of lactation, poor nutrition, extreme ...
DNase activity in Costa Rican crotaline snake venoms: quantification of activity and identification of electrophoretic variants.
DNase activity of Costa Rican crotaline snake venoms from the genera Bothrops, Crotalus and Lachesis was quantified by an enzymodiffusion method on agarose/DNA gels containing ethidium bromide. The reaction is detected as ...
Analysis of Phalaenopsis Bud Length during Meiosis to Predict Pollen Fertility
Phalaenopsis orchids are a very important commercial crop in tropical countries. Nonetheless hybrids feature variations in pollen fertility due to widespread chromosomal rearrangements in meiotic chromosomes. Usually each ...
Exposure of dogs to spotted fever group rickettsiae in urban sites associated with human rickettsioses in Costa Rica
The zoonotic transmission cycles of Rickettsia rickettsii and other spotted fever group (SFG) rickettsiae in Latin America have usually been associated with rural or sylvatic environments, although domestic dogs can be ...
The effect of myotoxins isolated from Bothrops snake venoms on multilamellar liposomes: relationship to phospholipase A2, anticoagulant and myotoxic activities
The effect of four myotoxins isolated from Bothrops snake venoms on the release of peroxidase trapped in large multilamellar liposomes was studied and correlated to their phospholipase A2, myotoxic and anticoagulant ...
Experimental myonecrosis induced by the venoms of South American Micrurus (coral snakes)
Venoms from 11 taxa of Micrurus (coral snakes) from Brazil and Colombia were tested for myotoxic activity in mice. All venoms, except that of M. surinamensis, induced myotoxicity as judged by the increase in plasma creatine ...
