AI Article Synopsis

  • The study conducted in Guanaceví, Durango, Mexico, focused on long-eared bats (genus Corynorhinus) and their ectoparasites in abandoned mines.
  • Researchers collected samples of Corynorhinus mexicanus and Corynorhinus townsendii across four seasons, totaling 23 and 18 specimens respectively, and identified 98 ectoparasites from 10 different species.
  • Notably, five ectoparasite species were identified for the first time on C. mexicanus and four on C. townsendii, with Macronyssus cyclaspis and Trichobius corynorhini showing the highest infestation rates, while seasonal differences in ectoparasite counts were not

Article Abstract

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.

Effect of seedling size on post-planting growth and survival of five Mexican species and their hybrids.

Instituto de Silvicultura e Industria de la Madera, Universidad Juárez del Estado de Durango, Durango, Durango, Mexico.

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.

Effect of statins on arterial wall inflammation as assessed by 18F-FDG PET CT: an updated systematic review and meta-analysis.

J Inflamm (Lond)

Center for Global Health Research, Saveetha Institute of Medical and Technical Sciences, Saveetha Medical College and Hospitals, Saveetha University, Chennai, India.

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.

The CYP2C19 enzyme is implicated in the metabolism of several clinically used drugs. 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.
