Drugs such as angiotensin-converting enzyme inhibitors and angiotensin receptor blockers can improve muscle function and exercise capacity, as well as preventing, attenuating or reversing age-related losses in muscle mass, however, the exact mechanisms by which these drugs affect muscle cells, are not yet fully elucidated. Moreover, the potential epigenetic alterations induced in skeletal muscle tissue are also largely unexplored. The aim of this study was to evaluate if enalapril or losartan can change the physical performance and epigenetic profile of skeletal muscle in spontaneously hypertensive rats (SHRs).

The aim of the study was to evaluate the effect of metabolic syndrome (MetS) on female Swiss mice subjected to severe polymicrobial sepsis induced by cecal ligation and puncture (CLP). MetS was induced in neonatal Swiss mice by subcutaneous injection of monosodium glutamate (MSG) at 4 mg/g body weight from day 1 to day 5 after birth, while animals in the control group (CTL) were treated with equimolar saline solution at the same volume and period. On the 75th day of life, the CLP model was used to induce severe polymicrobial sepsis.

A feature of Candida tropicalis is its ability to undergo phenotypic switching that can affect antifungal sensitivity and virulence traits. Here, we investigated the effect of switching on alterations at the cellular structure level of C. tropicalis morphotypes and whether exposure to fluconazole (FLC) in vitro could be associated with these alterations in a morphotype-dependent manner.

Nanomaterials composed of non-nutritive elements are gaining momentum in agriculture. In view of these advances, this study aimed to synthesize and assess the effects of silver (Ag) and cobalt (Co) nanoparticles as seed treatment in maize crops. Nanoparticles were synthesized by coprecipitation and characterized by X-ray diffractometry, transmission electron microscopy, surface area analysis, and Fourier-transform infrared spectroscopy.

Human papillomavirus (HPV) is involved in virtually all cases of cervical cancer. However, HPV alone is not sufficient to cause malignant development. The effects of chronic inflammation and the interaction of immune components with the microenvironment infected with the high-risk HPV type (HR) may contribute to cancer development.

The use of C-type natriuretic peptide (CNP) in the interaction with the oocyte and in the temporary postponement of spontaneous meiosis resumption has already been well described. However, its action in pre-implantation developmental-stage embryos is yet to be understood. Thus, our study aimed to detect the presence of the canonical CNP receptor (natriuretic peptide receptor, NPR2) in germinal vesicle (GV)-, metaphase II (MII)-, presumptive zygote (PZ)-, morula (MO)-, and blastocyst (BL)-stage embryos and, later, to observe possible modulations on the embryos when co-cultured with CNP.

Studies have shown that corn ( L.) proteins, mainly α-zein, have the potential to act on therapeutic targets related to non-communicable chronic diseases, such as high blood pressure and type 2 diabetes. Enzymatic hydrolysis of proteins present in foods can result in a great diversity of peptides with different structures and possible bioactivities.

The SO-generating pads contain different concentrations of sodium metabisulfite, which absorbs water from the grapes' transpiration, releasing SO gas, and there are slow-(SlowSO) and dual (DualSO)-releasing pads (fast release in the first 48 h and slow for up to 60 days). The ultra-fast SO-generating pad (FieldSO) releases the SO quickly for up to 6 h, and it was designed to be used soon after the harvest and until the grapes' packaging. The goal was to study the effect of FieldSO associated with SlowSO and DualSO pads on gray mold incidence and physicochemical and appearance characteristics of 'Italia' table grapes.

This study aimed to evaluate the quality and oxidative stability of chicken burger and mortadella prepared with fillets affected by white striping (WS) myopathy as compared with products prepared with normal fillets (control) There were no differences in pH, L*, or b* between treatments (WS vs. control); however, water holding capacity was higher in control burgers and mortadellas. In burgers, the use of WS fillet led to an increase in lipid content and a reduction in moisture content.
