Biodiversity conservation is challenged not only by the lack of knowledge about species distributions but also by an often-overlooked factor: the unquantifiable uncertainty in the quality and reliability of the data used for decision-making. This challenge is intensified for migratory and overexploited species, such as the goliath catfish Brachyplatystoma filamentosum (‘piraíba’), where management decisions based on data of un...

Passion fruit, a tropical species cultivated across various nations, faces challenges in expanding its cultivation areas due to several constraints, including total crop losses, caused by the fruit woodiness virus. In Brazil, this condition is attributed to the cowpea aphid-borne mosaic virus (CABMV), and currently, no passion fruit cultivars are resistant to this virus. This study integrates classical breeding and molecular a...

Background Cardiovascular diseases are the leading cause of death worldwide. An important mechanism involved is the disruption in protein homeostasis by overactivation of the classical axis of the renin-angiotensin system. The counterregulatory axis counteracts these effects; however, the MrgD receptor has recently been described, and its effects are unknown. Thus, this study aims to evaluate the impact of MrgD deficiency on c...

Bat-borne coronaviruses are of increasing interest due to their potential for zoonotic spillover, particularly within the Betacoronavirus genus. Partial genomic sequences related to MERS-like CoV was identified in multiple hosts, including humans, camelids, and bats from the families Vespertilionidae and Molossidae. In this study, we investigated the presence of coronaviruses in 65 Molossus molossus bats captured in southern B...

Halophilic microorganisms are central to biotechnology, bioremediation, and astrobiology because they persist under extreme and polyextreme conditions analogous to extraterrestrial environments. Although metagenomics has transformed the study of halophilic biodiversity, available datasets remain fragmented and unevenly documented. To assess how halophilic metagenomic research reflects the global exploration of hypersaline envi...

This pilot study evaluated the short- and mid-term outcomes of intra-articular allogeneic canine adipose-derived stem cell (ADSC) enriched secretome in dogs undergoing tibial plateau levelling osteotomy (TPLO), focusing on postsurgical recovery and osteoarthritis (OA) progression. Twenty client-owned dogs were randomly assigned ( n = 10 per group) to a control group (CG), receiving placebo, or a treated group (ADSC-Se), receiv...

This study evaluates the potential impacts of hypothetical nuclear accidents at the Almirante Álvaro Alberto Nuclear Power Plant (CNAAA), located in Angra dos Reis (RJ), in the southeastern region of Brazil, through the integration of advanced atmospheric modeling and Geographic Information Systems (GIS). The study area is characterized by complex environmental features, including mountainous terrain, remnants of the Atlantic...

The seasonality of forage production is one of the main challenges in semi-arid regions, where environmental conditions limit agricultural productivity. One promising option is the use of elephant grass ‘BRS Capiaçu’, together with deficit irrigation. This study evaluated the impact of different irrigation depths with brackish water (50%, 75%, 100% and 125% of the reference evapotranspiration – ET 0 ) on the productive, physio...

Adopting resilient practices is crucial to balancing food production and crop sustainability in semiarid regions. Therefore, adopting systems that provide greater stocks of water, carbon, and nutrients at the soil-plant interface is crucial. The objective of this study was to assess water, carbon, and nutrient stocks in the soil-plant systems of irrigated forage crops in the semiarid region of Brazil. The study was conducted i...

Lutzomyia longipalpis (Lutz & Neiva, 1912) is the main vector of the protozoan Leishmania infantum , the etiologic agent of Visceral Leishmaniasis (VL) in the American continent. In Brazil, the control of this sand fly species is difficult due to its resistance to chemical insecticides. The present study had the objectives of determining the chemical composition of Piper marginatum essential oil (EO) and to evaluating its ovic...
