Equine endometrial bacteria inhibition by metabolite and extracellular vesicles of Lactobacillus acidophilus and lactiplantibacillus plantarum.

Endometritis is one of the main reproductive disorders in mares and due to the increasing prevalence of antibiotic resistance, the use of probiotics in the prevention and treatment of endometritis in mares has gained interest, given their potential to restore and maintain a healthy uterine microbiota. Therefore, the aim of this study was to evaluate the antimicrobial properties of total metabolites of Lactobacillus acidophilus (LA) and Lactiplantibacillus plantarum (LP) against common equine endometrial pathogenic bacteria in vitro (Acinetobacter baumannii, Escherichia coli (1), Escherichia coli (2), Escherichia coli (3), Escherichia coli (4), Enterobacter cloacae, Streptococcus equi, Staphylococcus warneri, Actinobacillus equi and Klebesiella pneumoniae), as well as to assess their low molecular weight metabolites (loM) and extracellular vesicle (EVs) inhibition capacity over a multidrug-resistant E. coli isolated from mares with clinical endometritis.

Metagenomic immunoglobulin sequencing reveals IgA coating of microbial strains in the healthy human gut.

IgA, the primary human antibody secreted from the gut mucosa, shapes the intestinal microbiota. Methodological limitations have hindered defining which microbial strains are targeted by IgA and the implications of binding. Here we develop a technique, metagenomic immunoglobulin sequencing (MIg-seq), that provides strain-level resolution of microbes coated by IgA and use it to determine IgA coating levels for 3,520 gut microbiome strains in healthy human faeces.

Portuguese Society of Ophthalmology and Portuguese Society of Human Genetics Joint Clinical Practice Guidelines for Genetic Testing in Inherited Retinal Dystrophies.

The Portuguese Society of Ophthalmology and the Portuguese Society of Human Genetics developed clinical practice guidelines to streamline genetic testing for inherited retinal dystrophies (IRDs), underlining the critical role of molecular diagnosis in enhancing patient care. Genetic testing is pivotal in diagnosis, genetic counselling, prognosis and access to clinical trials, and new gene-specific therapies. These guidelines recommend genetic testing in all IRD patients and provide a detailed assessment of available testing methods, ensuring that genetic counselling is integrated into ophthalmic care.

Assessing radiation-induced enzyme activation in Aedes aegypti: Potential challenges for SIT-based vector management.

This study characterizes the Aedes aegypti population from Fernando de Noronha Island, Pernambuco, Brazil, prior to implementing the Sterile Insect Technique (SIT). The main objective was to assess changes in glutathione S-transferase (GST) enzyme activity, previously linked to cypermethrin resistance in this population, in 2010. GST activity was measured in both male and female mosquitoes, masse produced in lab, after exposure to ionizing radiation.

Application of the transgender male voice questionnaire in a Brazilian population sample.

Objectives: The aim of this study was to adapt and apply the Portuguese version of the Transgender Man Voice Questionnaire in a sample of Brazilian transgender men and to investigate the relationship between voice satisfaction and hormone therapy duration. In addition, we suggest reducing and reformulating the questionnaire for screening.

Methods: We conducted a cross-sectional study of 31 transgender men aged 18-50 years undergoing hormone therapy who answered a questionnaire adapted from the Transgender Woman Voice Questionnaire, validated in Portuguese.
