Extractive optimization of bioactive compounds in aerial parts of using Box-Behnken experimental design.

is known for its potential antioxidant and anti-inflammatory properties, attributed to triterpenes, flavonoids, and tannins. This study aimed to optimise the extraction process for aerial parts of using vortex extraction. A Box-Behnken experimental design coupled with response surface methodology was employed to evaluate the effects of three independent variables: sample-to-solvent ratio, velocity, and temperature.

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.
