Zinc-L-Selenomethionine Improves Growth and Hemato-Biochemical Parameters at Low but not at High Stocking Density for Nile Tilapia Males.

The study aimed to examine the interaction between diets supplemented with zinc-L-selenomethionine (ZnSeMet) and two stocking densities (SD) on Nile tilapia (Oreochromis niloticus) males. Four extruded diets were formulated: 0.0, 0.

Prevalence and factors associated with intestinal parasitosis in children from an urban slum in Brazil: a cross-sectional study.

Objective: This study aimed to estimate the prevalence and investigate the factors associated with intestinal parasitic diseases in children from an urban slum in Brazil.

Methods: A cross-sectional study was conducted in children living in SEWA community, an urban slum located in Araguari, Minas Gerais, Brazil. The prevalence of intestinal parasitosis was determined via stool parasitological examination by spontaneous sedimentation.

Assessing neighbourhood-scale BTI spray applications and laboratory-based mortality testing on larval development.

Mosquitoes, particularly , pose significant public health risks by transmitting diseases like dengue, zika and chikungunya. var. (BTI) is a crucial larvicide targeting mosquitoes while sparing other organisms and the environment.

Changes in Availability and Affordability on the University Food Environment: The Potential Influence of the COVID-19 Pandemic.

Background: The COVID-19 pandemic has had an impact on the eating habits of the general population, among other reasons, because it has affected access to commercial establishments since some of them closed. This study aimed to describe potential changes that occurred between 2019 and 2022 in the availability and affordability of food and beverages in the food environment of a Brazilian public university.

Methods: Cross-sectional and descriptive study conducted at a public university located in Rio de Janeiro, Brazil.

Inflammatory Monocytes Increase Prior to Detectable HIV-1 Rebound Viremia.

The persistence of HIV-1 proviruses in latently infected cells allows viremia to resume upon treatment cessation. To characterize the resulting immune response, we compare plasma proteomics and single-cell transcriptomics of peripheral blood mononuclear cells (PBMCs) before, during, and after detectable plasma viremia. We observe unique transcriptional signatures prior to viral rebound including a significant increase in CD16 monocytes with increased anti-viral gene expression.
