As a part of an inventory of bats in abandoned mines at the municipality of Guanaceví, Durango, Mexico, a sample of long-eared bats (genus Corynorhinus) was collected and ectoparasites were taken. Twenty-three specimens of Corynorhinus mexicanus Allen, 1916, and 18 of Corynorhinus townsendii (Cooper, 1937) were collected in four sampling periods coincident with the seasons. In total, 98 ectoparasites of 10 species and seven families were examined. Five species are recorded for the first time on C. mexicanus and four on C. townsendii. Macronyssus cyclaspis and Trichobius corynorhini had the highest frequency of infestation in both bats. Differences in number of arthropods per bat among seasons were nonsignificant for both species.

Background: The genus Metlapilcoatlus was recently erected to include six species of stout venomous snakes, known as the jumping pitvipers, which inhabit mountainous areas of Mesoamerica. This group maintains affinity with Atropoides picadoi, another jumping pitviper with restricted distribution in Costa Rica and Panama. Although the venom of A.

Introduction: Hip fractures in the elderly pose a significant clinical challenge, with high short-term mortality rates. The Nottingham Hip Fracture Score (NHFS) has proven useful in predicting 30-day mortality in European and Asian populations, but its validity in the Mexican population has not been widely assessed.
General Objective: To validate the NHFS in predicting 30-day mortality following hip fracture in a Mexican population.

Background: Seedling growth and survival depend on seedling quality. However, there is no experimental evidence showing that the seedling dimensions of the abundant, economically important and widely distributed tree species , , , , and and their hybrids effectively improve survival and growth in reforestations and plantations in Mexico. Therefore, the aim was to evaluate the influence of initial morphological parameters of 2,007 nursery seedlings of these species and their hybrids on their growth and survival 44 months after planting in the Sierra Madre Occidental, Mexico.

Background: Pathogenesis of atherosclerosis is largely mediated by inflammatory process. Statins are lipid-lowering drugs which also have anti-inflammatory effects. 18 fluorine radiolabeled fluorodeoxyglucose (18 F-FDG) positron emission tomography-computed tomography (PET-CT) is considered to be a good indicator of arterial wall inflammation.

Its phenotype is usually predicted by genotyping and indicates the expected enzymatic activity for each patient. However, with a few exceptions, genotyping has not resulted in a reliable prediction of the metabolizer status, since most of the evidence currently available for this prediction comes from research into populations of predominantly European ancestry.
