Genetic characterization of paternal lineages by Y-STR in three sample populations in Northeastern Brazil.

Genetic markers of the Y chromosome are powerful tools for investigating paternal ancestry and are widely used in population and forensic genetics. However, in order to obtain statistics with a higher degree of certainty using these markers, it is necessary to obtain haplotypic frequencies from a representative database, as well as knowing the diversity and structure of the population. The aim of this study was to investigate the genetic diversity of a sample of 1114 unrelated men from three states in the Northeast of Brazil: Paraíba, Pernambuco and Ceará, through the analysis of 23 Y-STRs and to contribute to the expansion of the Brazilian database on these markers.

Differential bioaccumulation and histopathological changes induced by iron oxide nanoparticles and ferric chloride in the neotropical snail Biomphalaria glabrata.

Iron oxide nanoparticles (IONPs) are prominent in nanomedicine, cosmetics, and environmental applications. However, their increasing production, use, and release into the environment raises concerns about their potential risks to aquatic life and human health. This study aimed to evaluate the bioaccumulation, as concentration of small, medium and large iron aggregates in the digestive tubules, histopathological changes, and inflammatory responses in the freshwater snail Biomphalaria glabrata following chronic exposure to gluconic-acid functionalized IONPs (GLA-IONPs) compared to their dissolved counterpart (FeCl).

Fibrinolytic enzyme from Arthrospira platensis and its effects on breast cancer cells: Exploring its potential as an innovative therapy.

Subsequently, two different cytotoxic assays (MTT and NR) and hemolysis test were performed to evaluate FEAP's safety.

Cross‑Cultural Validation of the Chronic Rhinosinusitis Patient-Reported Outcomes (CRS-PRO) Questionnaire in Portuguese.

Introduction Chronic rhinosinusitis (CRS) presents with different clinical patterns with variable responses to treatment. Clear criteria for specifying disease severity and assessing symptom control are lacking in the current literature. We aimed to perform a cross-cultural adaptation of the chronic rhinosinusitis patient-reported outcomes (CRS-PRO), creating a Portuguese version to use as a routine questionnaire in the evaluation of patients with CRS.

Jerked beef as an ultraprocessed convenience food: Desalting strategies to minimize the impact on lipid and protein oxidation.

Jerked beef (JB) is a high-protein convenience food but shows high degree of oxidation owing to its severe ultraprocessing. This study aimed to investigate the effect of desalting processes on oxidative stability of JB. JB were submitted to five desalting procedures: immersion in water at room temperature for 12 h without changing the water (AT12); immersion in water at room temperature for 12 h followed by boiling for 30 min and changing the water between the two procedures (AT12 + C30); immersion in boiled water for 10, 20, and 30 min (C10, C20, and C30, respectively).

Bioactive Peptides from Corn ( L.) with the Potential to Decrease the Risk of Developing Non-Communicable Chronic Diseases: In Silico Evaluation.

Studies have shown that corn ( L.) proteins, mainly α-zein, have the potential to act on therapeutic targets related to non-communicable chronic diseases, such as high blood pressure and type 2 diabetes. Enzymatic hydrolysis of proteins present in foods can result in a great diversity of peptides with different structures and possible bioactivities.

Children who claim previous life memories: A case report and literature review.

Objective: Academic investigation of thousands of children who claim past-life memories has been developed worldwide for five decades. However, despite the scientific and clinical significance of this substantial body of research, most clinicians and scientists are not aware of it. This study aims to report a case of a child who claimed memories that match his deceased granduncle's life and to perform a literature review of the main characteristics and implications of children's past-life claims.

Hazardous fipronil insecticide effects on aquatic animals' health: Historical review and trends.

Fipronil (FIP) is a broad-spectrum and highly efficient insecticide used against several arthropod pests, such as parasitic mites and insect pests affecting both animals and plants. Given its several benefits, FIP is widely used in the agricultural and veterinary medicine fields, but its indiscriminate use can have ecotoxic effects on non-target species. Thus, the current study aimed to summarise and critically analyse FIP's ecotoxicity in aquatic animals.

Ecotoxicological Effects of Emerging Contaminants on Aquatic Species.

In this sense, it becomes relevant to understand the knowledge of the population about the disease.

Brain Abscesses in Domestic Ruminants: Clinicopathological and Bacteriological Approaches.

Brain abscesses in ruminants often arise from primary infection foci, leading to an unfavorable prognosis for affected animals. This highlights the need for comprehensive studies on brain abscesses across different ruminant species. We retrospectively investigated medical records of epidemiological, clinical, neuroimaging, anatomopathological, and bacteriological findings in six ruminants (three goats, two cows, and one sheep) diagnosed with brain abscesses.

Disentangling the veil line for Brazilian biodiversity: An overview from two long-term research programs reveals huge gaps in ecological data reporting.

The lack of synthesized information regarding biodiversity is a major problem among researchers, leading to a pervasive cycle where ecologists make field campaigns to collect information that already exists and yet has not been made available for a broader audience. This problem leads to long-lasting effects in public policies such as spending money multiple times to conduct similar studies in the same area. We aim to identify this knowledge gap by synthesizing information available regarding two Brazilian long-term biodiversity programs and the metadata generated by them.
