Cryopreservation and transplantation of spermatogonia stem cells in piracanjuba Brycon orbignyanus (Characiformes: Characidae), an endangered fish species.

Piracanjuba (Brycon orbignyanus) is an endangered fish species from the Neotropical region. The establishment of a cryobank using spermatogonial stem cells (SSCs) and subsequent production of a germline chimera is thus a promising strategy for such species. In the present work, procedures for the isolation and cryopreservation of piracanjuba SSCs and subsequent transplantation into sterile recipients were established.

Childhood obesity is associated with a high degree of metabolic disturbance in children from Brazilian semi-arid region.

Projected to impact 310 million children by the next decade, childhood obesity is linked to serious health issues like metabolic disturbance and cardiovascular diseases. This study introduces a novel approach for the integrated assessment of inflammatory, glycemic and lipid disorders in obese children in resources-limited settings and also identifies key factors contributing to these changes. Conducting a cross-sectional analysis of 231 children aged 5-12 years from public schools in Brazil's semi-arid region, the research involved collecting medical history, anthropometric measurements, and blood samples to analyze glycemic and lipid profiles, along with C-reactive protein levels.

Higher Bifidobacterium spp. fecal abundance is associated with a lower prevalence of hyperglycemia and cardiovascular risk markers among schoolchildren from Bahia, Brazil.

The gut microbiome has recently been the subject of considerable scientific interest due to its essential bodily functions. Several factors can change the composition and function of the gut microbiome, and dietary habits are one of the most important contributors. Despite the recognition of the probiotic effects related to the genus Bifidobacterium spp.

Ultra-Processed Food Consumption Is Related to Higher Trans Fatty Acids, Sugar Intake, and Micronutrient-Impaired Status in Schoolchildren of Bahia, Brazil.

Ultra-processed food (UPF) consumption impacts nutrient intake and plays an important role in non-communicable diseases (NCD), even among schoolchildren. This cross-sectional study aimed to characterize the food consumption of this population and its relationship with laboratory and anthropometric aspects. A sample of 190 subjects aged 5 to 19 y was randomly selected for dietary, laboratory, and anthropometric assessment.

Deaths and hospitalizations of victims of non-drug toxicological events in Brazil, 2009 to 2018.

Objective: to determine the rate of hospitalizations due to acute non-drug poisoning (NDP) events and to analyze mortality arising from these health conditions in Brazil from 2009 to 2018.

Methods: this was a time-series study using Prais-Winsten regression to analyze records of hospitalizations for "treatment of intoxication or poisoning due to exposure to non-drug substances" held on the Hospital Information System.

Results: there were 125,570 hospitalizations due to NDP.

Establishing a model fish for the Neotropical region: The case of the yellowtail tetra in advanced biotechnology.

The use of model organisms is important for basic and applied sciences. Several laboratory species of fishes are used to develop advanced technologies, such as the zebrafish (), the medaka (), and loach species ( spp). However, the application of these exotic species in the Neotropical region is limited due to differences in environmental conditions and phylogenetic distances.

Stigma as a Source of Stress for Adolescent Mothers and Their Babies.

Adolescent pregnancy and the babies of teen mothers have been a focus of attention and concern for many years. The literature on the health of pregnant and parenting teens, however, is largely silent about the impact of stigma on them and their children. Stigma is a pervasive cultural attitude, which leads us to overlook potentially good outcomes for this vulnerable population and contributes to poor outcomes for these mothers and babies.

Deafness in the Brazilian care policy: a genealogical analysis.

Deafness can be understood from the clinical-therapeutic and the socio-anthropological perspectives. The study aims to perform a genealogical analysis of deafness; that is, an analysis of the practices of knowledge and power in Brazilian health policy. This is a qualitative, documentary study based on the theoretical assumptions of Foucault.

An Environmental and Nutritional Evaluation of School Food Menus in Bahia, Brazil That Contribute to Local Public Policy to Promote Sustainability.

Aimed at improving the quality of school meals, the Sustainable School Program (SSP) implemented low-carbon meals, twice a week, in 155 schools of 4 municipalities, reaching more than 32,000 students. This study evaluated the environmental impact and nutritional viability of this intervention for this population. The 15 most repeated meals from the conventional and sustainable menus were selected, and we considered the school age group and number of meals served per student/day.

Deaths and hospitalizations resulting from poisoning by prescription and over-the-counter drugs in Brazil.

Objective: To estimate the incidence of hospitalizations considering drug intoxication and the mortality of these diseases in Brazil, given trends from 2009 to 2018.

Methods: Data on hospital admissions and deaths come from DATASUS and demographic data from the Brazilian Institute of Geography and Statistics (IBGE). Hospital admissions with Autorização para Internação Hospitalar (AIH - Authorization for Hospital Admission) indicated as a procedure "treatment of intoxication or poisoning due to exposure to drugs and substances for non-drug use" were selected, with only cases of hospitalization due to drug intoxication being analyzed.

3D Mesoscale Finite Element Modelling of Concrete under Uniaxial Loadings.

Concrete exhibits a complex mechanical behavior, especially when approaching failure. Its behavior is governed by the interaction of the heterogeneous structures of the material at the first level of observation below the homogeneous continuum, i.e.

Molybdenum-isotope signals and cerium anomalies in Palaeoproterozoic manganese ore survive high-grade metamorphism.

Molybdenum (Mo) and its isotopes have been used to retrieve palaeoenvironmental information on the ocean-atmosphere system through geological time. Their application has so far been restricted to rocks least affected by severe metamorphism and deformation, which may erase or alter palaeoenvironmental signals. Environmental Mo-isotope signatures can be retrieved if the more manganese (Mn)-enriched rocks are isotopically depleted and the maximum range of δMo values is close to the ~2.

An unusual abdominal wall mass in a child.

Abdominal tumors are one of the most common types of pediatric cancer. Therefore, they should always be included in the differential diagnosis of abdominal masses. Here, we present the case of a child whose initial hypothesis of diagnosis contemplated this possibility.

Assessment of heavy metals in the particulate matter of two Brazilian metropolitan areas by using Tillandsia usneoides as atmospheric biomonitor.

Purpose: The aims of this paper were to quantify the heavy metals (HM) in the air of different sites in Rio de Janeiro (RJ) and Salvador (SA) using Tillandsia usneoides (Bromeliaceae) as a biomonitor, and to study the morphology and elemental composition of the air particulate matter (PM) retained on the Tillandsia surface.

Methods: Tillandsia samples were collected in a noncontaminated area and exposed to the air of five sites in RJ State and seven in SA for 45 days, in two seasons. Samples were prepared to HM quantification by flame atomic absorption spectrophotometry, while morphological and elemental characterizations were studied by using scanning electron microscopy.

Exposure to asbestiform minerals and radiographic chest abnormalities in a talc mining region of upstate New York.

A radiologist in New York reported a high prevalence of pulmonary fibrosis in St. Lawrence and Jefferson counties. The New York State Department of Health responded by conducting a case history study of radiographic abnormalities found in the lung parenchyma and pleura of residents in Lawrence and Jefferson counties, where tremolitic talc has been mined for many years.

Incidence of low birth weight among Love Canal residents.

The incidence of low birth weight among white live-born infants from 1940 through 1978 was studied in various sections of the Love Canal. A statistically significant excess was found in the historic swale area from 1940 through 1953, the period when various chemicals were dumped in this disposal site. Potential confounding factors such as medical-therapeutic histories, smoking, education, maternal age, birth order, length of gestation, and urban-rural difference did not appear to account for this observation.

Infant leukemia and paternal exposure to motor vehicle exhaust fumes.
