Malnutrition/exercise interaction in the rat mother-pup dyad: a behavioral and electrophysiological analysis.

Objectives: Maternal protein malnutrition alters brain functioning, impairing fetal development. Physical exercise during gestation benefits the fetal organism from maternal adaptive changes that may be neuroprotective. This study evaluated the effect of a low-protein diet associated with maternal voluntary physical activity (VPA) on rats' behavioral and brain electrophysiological parameters in the mother-pup dyad.

Multiple introductions and sustained local transmission of in Southern Brazil between 2022-2023.

Mpox is a zoonotic viral disease caused by the (MPXV). Human cases have been mainly restricted to the African continent until the worldwide multi-country outbreak unfolded in 2022. We reconstructed epidemiological links of 53 MPXV infections using genomic epidemiology in Rio Grande do Sul State, southern Brazil, during 2022 and 2023.

Study of the Anti-MYC Potential of Lanostane-Type Triterpenes.

One of the most investigated molecular targets for anticancer therapy is the proto-oncogene , which is amplified and thus overexpressed in many types of cancer. Due to its structural characteristics, developing inhibitors for the target has proven to be challenging. In this study, the anti-MYC potential of lanostane-type triterpenes was investigated for the first time, using computational approaches that involved ensemble docking, prediction of structural properties and pharmacokinetic parameters, molecular dynamics (MD), and binding energy calculation using the molecular mechanics-generalized born surface area (MM-GBSA) method.

Sugar Cane ( L.) Waste Synthesized Si,N,S-Carbon Quantum Dots as High-Performance Corrosion Inhibitors for Mild Steel in Hydrochloric Acid.

This work reports the obtention of Si,N,S-CQDs from sugar cane bagasse and their inhibitory action on the mild steel corrosion in 1 mol L HCl solution. The CQDs were successfully obtained and characterized by X-ray photoelectron spectroscopy, Fourier-transform infrared spectroscopy, Dynamic light scattering, Raman, and UV-vis techniques, also showing endogenous self-doping. The anti-corrosive activity of CQDs was investigated by gravimetric tests, potentiodynamic polarization curves, electrochemical impedance measurements, atomic force microscopy, and scanning electron microscopy.

The nasal mycobiome of individuals with allergic rhinitis and asthma differs from that of healthy controls in composition, structure and function.

Allergic rhinitis (AR) and asthma (AS) are two of the most common chronic respiratory diseases and a major public health concern. Multiple studies have demonstrated the role of the nasal bacteriome in AR and AS, but little is known about the airway mycobiome and its potential association to airway inflammatory diseases. Here we used the internal transcriber spacers (ITS) 1 and 2 and high-throughput sequencing to characterize the nasal mycobiome of 339 individuals with AR, AR with asthma (ARAS), AS and healthy controls (CT).
