Objectives: To identify the occurrence of risk of disease resulting from work, among outsourced workers.

Methods: Quantitative, observational, analytical and cross-sectional study, with application of the Inventário de Trabalho e Riscos de Adoecimento in 187 workers of a company that supplies and manages human resources for third parties, under contract with a Federal University, located in the state of Minas Gerais.

Capturing clinically relevant attributes through direct whole genome sequencing of stool.

is the leading bacterial cause of infectious intestinal disease, but the pathogen typically accounts for a very small proportion of the overall stool microbiome in each patient. Diagnosis is even more difficult due to the fastidious nature of in the laboratory setting. This has, in part, driven a change in recent years, from culture-based to rapid PCR-based diagnostic assays which have improved diagnostic detection, whilst creating a knowledge gap in our clinical and epidemiological understanding of genotypes - no isolates to sequence.

Analysis of physical traits, clinical parameters, and energy metabolism of in vivo- and in vitro-derived Flemish newborn calves during the first day of life.

Studies investigating physiological deviations from normality in newborn calves derived from in vitro fertilization procedures remain important for the understanding of factors that reduce calf survival after birth. The aim of this study was to investigate parameters affecting health and welfare of newborn Flemish calves derived from in vitro embryo production (IVP) in the first hours of life in comparison to in vivo-derived calves. Physical traits of newborn calves and fetal membranes (FM) were recorded soon after birth.

Development and characterization of a novel variant of long-acting bovine follicle-stimulating hormone (brscFSH).

Assisted reproduction is a key aspect of modern animal breeding, providing valuable assistance in improving breeding programs. In this field, the administration of exogenous hormones, such as follicle-stimulating hormone (FSH), plays a crucial role in the induction of multiple ovulations. However, commercial FSH used in veterinary practice has been derived primarily from pituitary glands, obtained mostly from pigs for nearly four decades.

Exploring the Potential of Olfactory Receptor Circulating RNA Measurement for Preeclampsia Prediction and Its Linkage to Mild Gestational Hypothyroidism.

Gestational hypothyroidism may lead to preeclampsia development. However, this pathophysiological is unknown. We expect to find a shared mechanism by comparing hypothyroidism and preeclampsia.

Kinins: Locally formed peptides during inflammation with potential use in tissue regeneration.

Kinins are a set of peptides present in tissues and involved in cardiovascular regulation, inflammation, and pain. Here, we briefly comment on recent key findings on the use of kinins in regenerative medicine.

Disruptive 3D in vitro models for respiratory disease investigation: A state-of-the-art approach focused on SARS-CoV-2 infection.

COVID-19, along with most respiratory diseases in the medical field, demonstrates significant ability to take its toll on global population. There is a particular difficulty in studying these conditions, which stems especially from the short supply of models for detailed investigation, the specific therapeutic knowledge required for disease scrutinization and the occasional need of BSL-3 [Biosafety Level 3] laboratories for research. Based on this, the process of drug development is hampered to a great extent.

Kinin receptors regulate skeletal muscle regeneration: differential effects for B1 and B2 receptors.

Objective And Design: After traumatic skeletal muscle injury, muscle healing is often incomplete and produces extensive fibrosis. Bradykinin (BK) reduces fibrosis in renal and cardiac damage models through the B2 receptor. The B1 receptor expression is induced by damage, and blocking of the kallikrein-kinin system seems to affect the progression of muscular dystrophy.

Similar hypothyroid and sepsis circulating mRNA expression could be useful as a biomarker in onthyroidal illness syndrome: a pilot study.

Objective: Based on hypothetical hypothyroidism and nonthyroidal illness syndrome (NTIS) gene expression similarities, we decided to compare the patterns of expression of both as models of NTIS. The concordant profile between them may enlighten new biomarkers for NTIS challenging scenarios.

Materials And Methods: We used Ion Proton System next-generation sequencing to build the hypothyroidism transcriptome.

A Systematic Review on Alcohol Consumption among Non-Religious and Religious Adults.

Research has suggested that religiosity is a protective factor in alcohol use, but this is an area that could be further explored. To undertake a systematic review of the literature on drinking patterns and their relationship with religiosity and non-religiosity in adult populations. We searched for relevant studies using the PubMed, LILACS, Web of Science, Scopus, and Psych-INFO databases.

Freeze-dried Platelet-rich Plasma and Stem Cell-conditioned Medium for Therapeutic Use in Horses.

This study investigated platelet-rich plasma (PRP) and adipose stem cell-conditioned medium (ASC-CM) use as a strategy to accelerate tissue healing. Platelet-derived growth factor (PDGF) and vascular endothelial growth factor (VEGF) were quantified in fresh and freeze-dried PRP and ASC-CM, and a stability test was performed in the freeze-dried samples (90 and 180 days of storage). A cell proliferation test was performed using equine mesenchymal stem cell culture in reconstituted PRP gel mesh after freeze-drying.

Religious and secular spirituality: Methodological implications of definitions for health research.

The importance of spirituality as a research topic has been increasingly recognized, which has led to several studies on the topic. Areas including psychology, medicine, and nursing have produced studies on spirituality under a plurality of definitions and methods, which reveals the complexity of the theme. However, this has resulted in a range of potential problems, including: (1) the use of overlapping and contradictory terms between studies, or even within the same study, (2) research methodologies that do not fit the definitions (sometimes unreflectively) assumed by the authors, (3) difficulties, or even the impossibility, of comparing the results of studies, (4) controversies in respect of the inclusion/exclusion of secular groups in research on spirituality, and (5) ambiguous measurements, often being exclusively dependent on each participant's individual interpretation of what spirituality means.

The experience of teaching introductory programming skills to bioscientists in Brazil.

Computational biology has gained traction as an independent scientific discipline over the last years in South America. However, there is still a growing need for bioscientists, from different backgrounds, with different levels, to acquire programming skills, which could reduce the time from data to insights and bridge communication between life scientists and computer scientists. Python is a programming language extensively used in bioinformatics and data science, which is particularly suitable for beginners.

Physiological impact of the environment on the welfare of transgenic goats raised in a tropical climate.

The present study evaluated the general welfare state of two strains of transgenic goats bred in a region with a hot and humid tropical climate. Nine females were used, being three transgenic for human lysozyme (hLZ group), three transgenic for human glucocerebrosidase (hGCase group), and three non-transgenic (control group). The temperature and humidity index (THI) were recorded during the morning, afternoon, and evening.

Expression and characterization of a novel single-chain anti-vascular endothelial growth factor antibody in the goat milk.

Vascular endothelial growth factor (VEGF) has essential functions in angiogenesis, endothelial cell proliferation, migration, and tumor invasion. Different approaches have been developed to suppress tumor angiogenesis, which is considered a hallmark of cancer. Anti-VEGF monoclonal antibodies constitute an important strategy for cancer immunotherapy, which has been produced on several platforms.

Exposure of Salmonella biofilms to antibiotic concentrations rapidly selects resistance with collateral tradeoffs.

Most bacteria in nature exist in biofilms, which are inherently tolerant to antibiotics. There is currently very limited understanding of how biofilms evolve in response to sub-lethal concentrations of antimicrobials. In this study, we use a biofilm evolution model to study the effects of sub-inhibitory concentrations of three antibiotics on Salmonella Typhimurium biofilms.

Skeletal muscle healing by M1-like macrophages produced by transient expression of exogenous GM-CSF.

Background: After traumatic skeletal muscle injury, muscle healing is often incomplete and produces extensive fibrosis. The sequence of M1 and M2 macrophage accumulation and the duration of each subtype in the injured area may help to direct the relative extent of fibrogenesis and myogenesis during healing. We hypothesized that increasing the number of M1 macrophages early after traumatic muscle injury would produce more cellular and molecular substrates for myogenesis and fewer substrates for fibrosis, leading to better muscle healing.

Application of a cost-effective DNA extraction protocol for screening transgenic and CRISPR-edited primary goat cells.

The genotyping of genetically-modified cells is a crucial step in studies of transgenics and genomic editing with systems such as CRISPR/Cas. The detection of genome editing events can be directly related to the genotyping methodology used, which is influenced by its costs, since many experiments require the analysis of a large number of samples. The aim of this study was to compare the performance of direct lysis methods of genomic DNA (gDNA) extraction for the detection of knockins and knockouts in primary goat cells.

Circulating RNA Transcriptome of Pregnant Women with TSH Just Above the Trimester-Specific Reference and its Correlation with the Hypertensive Phenotype.

During gestation, a woman's body undergoes physiological changes that alter thyroid function. Pregnant women with hypothyroidism may exhibit gestational complications, including hypertension and preeclampsia. We investigated differentially expressed genes (DEGs) in circulating RNAs from pregnant women with TSH levels just above the normal range to determine the impact of a mild elevation of TSH in pregnancy.

Relationship between self-reported bruxism and periodontal status: Findings from a cross-sectional study.

Background: Several studies seek to prove the relationship between bruxism and periodontal status although it remains unclear and debatable. We aimed to assess the association between self-reported (SR) bruxism with the periodontal status in a large scale survey.

Methods: A total of 1064 individuals from the southern region of the Lisbon Metropolitan Area (Portugal) were enrolled.

Expression of a recombinant bacterial L-asparaginase in human cells.

Objective: L-Asparaginase (ASNase) is an enzyme used in the treatment of acute lymphoblastic leukemia (ALL). As the therapeutic ASNases has bacterial origin, severe side effects are associated with its use, among them hypersensitivity and inactivation of the enzyme. In this context, the objective of this work was to produce a recombinant ASNase of bacterial origin in human cells in order to determine the presence and consequences of potential post-translational modifications on the enzyme.

Basilar invagination associated with chiari malformation type I: A literature review.

Basilar invagination (BI) and Chiari malformation type I (CM-I) are very important anomalies that introduce instability and compression in the occipitocervical transition region and have complex clinical characteristics. These anomalies vary according to the affected structures. The present study revises current knowledge regarding the anatomy, anatomo-physiology, clinical manifestations, and radiological findings of these entities and the associated surgical treatment approaches.

Chromosome and plasmid-borne P promoters differ in sensitivity to critically low temperatures.

Temperature shifts trigger genome-wide changes in Escherichia coli's gene expression. We studied if chromosome integration impacts on a gene's sensitivity to these shifts, by comparing the single-RNA production kinetics of a P promoter, when chromosomally-integrated and when single-copy plasmid-borne. At suboptimal temperatures their induction range, fold change, and response to decreasing temperatures are similar.

SCIP: a single-cell image processor toolbox.

Summary: Each cell is a phenotypically unique individual that is influenced by internal and external processes, operating in parallel. To characterize the dynamics of cellular processes one needs to observe many individual cells from multiple points of view and over time, so as to identify commonalities and variability. With this aim, we engineered a software, 'SCIP', to analyze multi-modal, multi-process, time-lapse microscopy morphological and functional images.
