UnknownRecent taxonomic discoveries suggest a host-symbiont co-migration of <i>Russula</i> subsect. <i>Castanopsidum</i> with <i>Fagaceae</i> in the Americas.
Three members of ectomycorrhizal fungi belonging to Russula subsection Castanopsidum are described from neotropical montane forests dominated by species of Fagaceae in Panama and Colombia. Russula esperanzae sp. nov. from Colombia differs in the field from other members o...

UnknownColombian surgical outcomes study insights on perioperative mortality rate, a main indicator of the lancet commission on global surgery - a prospective cohort study.

Background

Surgical care holds significant importance in healthcare, especially in low and middle-income countries, as at least 50% of the 4.2 million deaths within the initial 30 days following surgery take place in these countries. The Lancet Commission on Global Surgery proposed six indic...

UnknownTransmission ecology of Trypanosoma cruzi by Rhodnius prolixus (Reduviidae: Triatominae) infesting palm-tree species in the Colombian Orinoco, indicates risks to human populations.

Background

Chagas disease, affecting approximately eight million individuals in tropical regions, is primarily transmitted by vectors. Rhodnius prolixus, a triatomine vector, commonly inhabits in ecotopes with diverse palm tree species, creating optimal conditions for vector proliferation. T...

UnknownEstimating the genetic structure of Triatoma dimidiata (Hemiptera: Reduviidae) and the transmission dynamics of Trypanosoma cruzi in Boyaca, eastern Colombia.
Chagas disease is considered a public health issue in Colombia, where many regions are endemic. Triatoma dimidiata is an important vector after Rhodnius prolixus, and it is gaining importance in Boyacá, eastern Colombia. Following the recent elimination of R. prolixus in the region, it is pivotal to...

UnknownMolecular survey of pyrethroid resistance mechanisms in Mexican field populations of Rhipicephalus (Boophilus) microplus.
Susceptibility to synthetic pyrethroids (SP s) and the role of two major resistance mechanisms were evaluated in Mexican Rhipicephalus microplus tick populations. Larval packet test (LPT), knock-down (kdr) PCR allele-specific assay (PASA) and esterase activity assays were conducted in tick populatio...

UnknownTriatoma venosa and Panstrongylus geniculatus challenge the certification of interruption of vectorial Trypanosoma cruzi transmission by Rhodnius prolixus in eastern Colombia.
Reactivation of Trypanosoma cruzi transmission by native vectors with different domiciliation capabilities is a major concern for Chagas disease control programs. T. cruzi transmission via intra-domestic Rhodnius prolixus was certified as interrupted by the Pan American Health Organization in Mirafl...

UnknownEvaluating the Use of UV Absorbance for the Differentiation of Humified From Non-Humified Materials.

Background

Products containing humic acids (HA) and fulvic acids (FA) have significant commercial potential; however, unknown to the consumer, some products may be mislabeled or contain adulterants. The prevalence of mislabeling and adulterants is found primarily in FA products. Using UV-Vis...

UnknownMulticountry research on comprehensive abortion policy implementation in Latin America: a mixed-methods study protocol.

Introduction

Access to comprehensive abortion care could prevent the death of between 13 865 and 38 940 women and the associated morbidity of 5 million women worldwide. There have been some important improvements in Latin America in terms of laws and policies on abortion. However, the predom...

UnknownDecreased glutathione synthesis in granulosa cells, but not oocytes, of growing follicles decreases fertility in mice†.
Prior studies showed that mice deficient in the modifier subunit of glutamate cysteine ligase (Gclm), the rate-limiting enzyme in synthesis of the thiol antioxidant glutathione, have decreased ovarian glutathione concentrations, chronic ovarian oxidative stress, poor oocyte quality resulting in earl...

UnknownThe Stress Response of the Holothurian Central Nervous System: A Transcriptomic Analysis.
Injury to the central nervous system (CNS) results in permanent damage and lack of function in most vertebrate animals, due to their limited regenerative capacities. In contrast, echinoderms can fully regenerate their radial nerve cord (RNC) following transection, with little to no scarring. Investi...
