Article Synopsis
  • Mosquito larvae, specifically Aedes aegypti, face varying levels of food availability and predation threats in freshwater habitats, and their development and life cycle can be significantly affected by these factors.
  • The study found that real non-lethal predation threats increased larval mortality (71%) and reduced individual sizes (7%), while also extending lifespans (19%), indicating significant stress on the larvae.
  • Overall, competition for resources and the threat of predation were crucial stressors affecting the larvae, but resource scarcity had a stronger impact on the fitness of survivors than predation risk, ultimately leading to decreased size and altered lifespans.

Microplastics, pervasive pollutants in aquatic environments, have been primarily studied for their impact on marine ecosystems. However, their effects on freshwater systems, particularly in forested phytotelmata habitats, remain understudied in Subtropical systems. This research examines the influence of varying microplastic concentrations (0.

Age-related changes in the mitochondrial status of human cumulus cells (hCCs) impact oocyte quality; however, the relationship between hCC mitochondrial (dys)function and reproductive aging remains poorly understood. This study aimed to establish the interplay between hCC mitochondrial dysfunction and women's reproductive potential. In this investigation, 266 women were enrolled and categorized into two groups based on their age: a young group (<35 years old) and an advanced maternal age (AMA) group (≥35 years old).

Major efforts to control the population of mosquitoes involve the use of synthetic insecticides, which can be harmful to the environment. Most plant compounds are eco-friendly and some of them have biocontrol potential, whereas a fraction of these compounds is released into the environment through the leaf-leaching process. We evaluated the effects of secondary compounds from and senescent leaf leachates on larval mortality, adult emergence time, and wing size using a microcosm approach.

Studies have shown that psychotropic drugs change rat behavior in the elevated plus-maze test (EPM). This study investigated whether static magnetic fields could alter alprazolam-induced rat behavior in the EPM. 66 male Wistar rats (270-300 g weight) were assigned to one of the following groups: Sham Magnetic + Saline (SMS), North Pole + Saline (NPS), South Pole + Saline (SPS), Sham magnetic + alprazolam (SMA), NP + alprazolam (NPA), and SP + alprazolam (SPA).

Background: The increasing and inappropriate use of antibiotics has increased the number of multidrug-resistant microorganisms to these drugs, causing the emergence of infections that are difficult to control and manage by health professionals. As an alternative to combat these pathogens, some monoterpenes have harmful effects on the bacterial cell membrane, showing themselves as an alternative in combating microorganisms. Therefore, the positive enantiomer α -pinene becomes an alternative to fight bacteria, since it was able to inhibit the growth of the species Escherichia coli ATCC 25922, demonstrating the possibility of its use as an isolated antimicrobial or associated with other drugs.

Aim: The aim of the present scoping review was to map the scientific evidence about diarrheal disease in indigenous children and the strategies that can be used to prevent it.

Methods: The subject headings were indigenous population; child; diarrhea; dysentery; epidemiology; and prevention, primary; also the following keywords characteristic, epidemiologic study; and children. The databases consulted were Latin American and Caribbean Health Sciences Literature, MEDLINE via the US National Library of Medicine/National Institutes of Health, and Web of Science.

Introduction: Non-dipper and extreme dipper blood pressure (BP) profiles are associated with a worse cardiovascular prognosis. The relationship between nocturnal BP profile and hypertensive retinopathy (HR) is not fully established.

Aim: To assess the association between the prevalence and severity of HR and nocturnal BP.

Background: Shortened treatment regimens for tuberculosis are under development to improve treatment outcomes and reduce costs. We estimated potential savings from a societal perspective in Brazil following the introduction of a hypothetical four-month regimen for tuberculosis treatment.

Methods: Data were gathered in ten randomly selected health facilities in Rio de Janeiro.

Objective: To sequentially and reliably apply both tubulin immunocytochemistry (ICC) and fluorescence in situ hybridization (FISH) to human fertilization failures, thus providing a tool for a multiple analysis of arrest.

Design: Analysis of human fertilization failures at several stages of arrest.

Setting: Academic and clinical institutions.
