Laboratory of Cellular Immunology Applied to Health, Oswaldo Cruz Foundation, FIOCRUZ Rondônia, Porto Velho, RO, Brazil; Department of Medicine, Federal University of Rondonia (UNIR), Porto Velho, RO, Brazil. Electronic address:

Phospholipases A (PLAs) are highly prevalent in Bothrops snake venom and play a crucial role in inflammatory responses and immune cell activation during envenomation. Despite their significance, the specific role of PLAs from Bothrops mattogrossensis venom (BmV) in inflammation is not fully understood. This study sought to isolate and characterize a novel acidic PLA from BmV, designated BmPLA-A, and to evaluate its effects on human umbilical vein endothelial cells (HUVECs), with a specific focus on cytotoxicity, adhesion, and detachment.

Smart indoor tourist attractions, such as smart museums and aquariums, require a significant investment in indoor localization devices. The use of Global Positioning Systems on smartphones is unsuitable for scenarios where dense materials such as concrete and metal blocks weaken GPS signals, which is most often the case in indoor tourist attractions. With the help of deep learning, indoor localization can be done region by region using smartphone images.

This study assessed qualitative and quantitative leukocyte evaluation as potential broiler chicken welfare indicators, contributing to the limited literature on white blood cell (WBC) morphology as a diagnostic tool for welfare. Broiler chicken welfare within four poultry houses (PH) 1 to 4, each on a different farm, was assessed using on-field indicators of affective states and health, and WBC morphology was examined. Affective states were evaluated using the Qualitative Behavior Assessment (QBA), with 25 behavioral expressions scored on a visual analogue scale (VAS) and grouped into two categories.

Identifying plantation lines in aerial images of agricultural landscapes is re-quired for many automatic farming processes. Deep learning-based networks are among the most prominent methods to learn such patterns and extract this type of information from diverse imagery conditions. However, even state-of-the-art methods may stumble in complex plantation patterns.

Introduction: The following work aims to compare the types and magnitude of risk events in patients with Schizophrenia and Bipolar Disorder and each of those groups with of a group of healthy siblings, exploring differences and similarities of the two psychotic disorders.

Methods: Retrospective interviews were conducted with 20 families to investigate maternal and obstetric health, social support and the presence of early trauma for the affected family members and healthy siblings. Mothers were interviewed with the Prenatal Psychosocial Profile and each family participant was assessed with the Early Trauma Inventory, Screening Questionnaire of the Genomic Psychiatry Cohort and the Diagnostic Interview for Psychosis and Affective Disorders.

Article Synopsis
  • A study was conducted to analyze the health of Holochilus chacarius, a small mammal, in a rice agroecosystem in the Pantanal region of Brazil using histopathology.
  • Lung, kidney, skin, liver, and reproductive system tissues were examined from 33 animals, revealing inflammation and damage, particularly in the lungs due to environmental factors like wildfires and heavy metals.
  • The research established a new matrix for classifying tissue damage and highlighted the potential of these small mammals as bioindicators for assessing environmental health.

Transcranial direct current stimulation (tDCS) has gained popularity as a method of modulating cortical excitability in people with physical and mental disabilities. However, there is a lack of consensus on its effectiveness in older individuals. This study aimed to assess the efficacy of a 2-month tDCS program for improving physical and mental performance in community-dwelling older individuals.

To critically analyze the evidence regarding changes in verbal and performance intelligence quotient (IQ) in patients with schizophrenia. An English-language-only search was conducted in the PubMed, Cochrane Library, and LILACS databases for articles with study objectives that included Wechsler Adult Intelligence Scale (WAIS) assessment of cognitive functions in patients with schizophrenia. Descriptors were defined based on Medical Subject Headings, where associations of psychotic disorders related to the schizophrenia spectrum were suggested, as well as the "Wechsler Scales" descriptor.

Our objective was to evaluate the productive parameters of ewes and their lambs in relation to ewe age and to develop models for predicting lamb weight at birth and weaning in a tropical warm-climate pasture. Individual data were collected from 273 ewes and 273 lambs, between 2013 and 2021. During this period all animals were kept on pastures of Brachiaria brizantha cv.

Article Synopsis
  • Chagas disease, sleeping sickness, and malaria are serious infections caused by protozoan parasites that affect millions globally.
  • In an experiment, synthetic polyalanine peptides were tested for their effectiveness against these parasites, showing that two specific peptides inhibited growth significantly.
  • Structural analysis revealed that one peptide interacts more deeply with cell membranes, suggesting different mechanisms of action, which supports the idea of using these peptides as potential treatments for sleeping sickness.

Schizophrenia (SCZ) and bipolar disorder (BD) exhibited altered activation in several brain areas, including the prefrontal and temporal cortex; however, a less explored topic is how brain connectivity and functional disturbances occur in non-Caucasian samples of SCZ and BD. Individuals with SCZ (n=20), BD (n=21), and healthy controls (HC, n=21) from indigenous and African ethnicity were submitted to clinical screening and functional assessments. Mood, compulsive and psychotic symptoms were also correlated to network dysfunction in each group.

Our hypothesis was that different whole oilseeds included in the diet for steers confined could alter the diversity of rumen bacteria compared to a diet without oilseeds or an exclusively forage diet. It was aimed to evaluate the effects of oilseeds inclusion in the diet on bacterial diversity in the solid fraction of the ruminal content of steers, by gene sequences of the conserved 16S rDNA region. Six crossbred steers castrated males, fitted with ruminal cannula were used in a 6 × 6 Latin square design, using 21-day period.
