NPPC and AREG supplementation in IVM systems alter mRNA translation and decay programs-related gene expression in bovine COC.

During oocyte meiosis resumption, a coordinated program of transcript translation and decay machinery promotes a remodeling of mRNA stores, which determines the success of the acquisition of competence and early embryo development. We investigated levels of two genes related to mRNA translation ( and ) and two related to mRNA degradation ( and ) machinery and found downregulated in -matured bovine oocytes compared to counterparts. Thereafter, we tested the effects of a pre-IVM step with NPPC and a modified IVM with AREG on the modulation of members of mRNA translation and degradation pathways in cumulus cells and oocytes.

A novel highly specific biotinylated MAC-ELISA for detection of anti-SARS-CoV-2 nucleocapsid antigen IgM antibodies during the acute phase of COVID-19.

The gold standard for diagnosing COVID-19 in the acute phase is RT-qPCR. However, this molecular technique can yield false-negative results when nasopharyngeal swab collection is not conducted during viremia. To mitigate this challenge, the enzyme-linked immunosorbent assay (ELISA) identifies anti-SARS-CoV-2 IgM antibodies in the initial weeks after symptom onset, facilitating early COVID-19 diagnosis.

Chapter 9.3: Current Concepts of Caries Removal in Daily Practice.

Although the discussion about the amount of carious dentin to be removed during cavity preparation is quite old, concepts for caries removal have evolved and changed considerably over the last decades. The antiquate understanding that it was necessary to eliminate the microbial contamination of a cavity before placing the restoration was replaced by the current knowledge that maintaining contaminated dentin beneath restorations is inevitable and is not associated with treatment failure. This chapter brings together the body of evidence behind carious dentin removal to indicate a conservative treatment, aiming to preserve both tooth vitality and structure.

GLIM criteria to identify malnutrition in patients in hospital settings: A systematic review.

Malnutrition is recognized as one of the main public health problems in hospitals. The Global Leadership Initiative on Malnutrition (GLIM) has established a global consensus on the criteria for diagnosing malnutrition in adults in hospital settings. This study aimed to evaluate the ability of the GLIM criteria as a tool to identify malnutrition in hospital settings and to compare the prevalence of malnutrition identified by GLIM criteria with that identified by other screening and/or nutrition assessment methods.

Improving acid and oxidative stress resistance using a prokaryotic gene identified by functional metagenomics.

Innovations in obtaining products from lignocellulosic biomass have been largely based on the improvement of microorganisms and enzymes capable of degrading these materials. To complete the whole process, microorganisms must be able to ferment the resulting sugars and tolerate high concentrations of product, osmotic pressure, ion toxicity, temperature, toxic compounds from lignocellulose pretreatment, low pH, and oxidative stress. In this work, we engineered laboratory and industrial strains by combining a gene () recovered from a metagenomic approach with different native and synthetic promoters to obtain improved acid and oxidative stress resistance.
