The radiological and sonographic findings of acute focal bacterial nephritis in 3 patients are presented. The sonographic appearance of a poorly marginated mass in the renal cortex, with echo amplitude less than the normal parenchyma and with poor transmission, should suggest the diagnosis of acute focal bacterial nephritis in a patient with pyrexia and a tender renal mass. These features of poor echogenicity and lack of posterior enhancement contrast with the presence of patchy echogenicity and posterior enhancement found in the renal abscess. This is of surgical importance, as the management may tend to be conservative in the one and surgical in the other.

Access to high-fat diet results in increased sensitivity to the psychostimulant effects of MDPV in mice.
Pharmacol Rep
January 2025
Research Laboratory CoreLab of the Medical University of Lodz, Łódź, Poland.
Background: The current study investigated the effects of high-fat diet on acute response to 3,4-methylenedioxypyrovalerone (MDPV) in mice. MDPV is a beta-cathinone derivative endowed with psychostimulant activity. Similarly to recreational substances, consumption of palatable food stimulates the mesolimbic dopaminergic system, resulting in neuroadaptive changes.

Center for Disease Mechanisms Research, Faculdade de Medicina da Universidade de Lisboa, Lisbon, Portugal.
Purpose: Major cardiovascular surgery imposes high physiologic stress, often causing severe organ dysfunction and poor outcomes. The underlying mechanisms remain unclear. This study investigated metabolic changes induced by major cardiovascular surgery and the potential role of identified metabolic signatures in postoperative acute kidney injury (AKI).
View Article and Find Full Text PDFThe idea of self-organized signal processing in the cerebral cortex has become a focus of research since Beggs and Plentz reported avalanches in local field potential recordings from organotypic cultures and acute slices of rat somatosensory cortex. How the cortex intrinsically organizes signals remains unknown. A current hypothesis was proposed by the condensed matter physicists Bak, Tang, and Wiesenfeld when they conjectured that if neuronal avalanche activity followed inverse power law distributions, then brain activity may be set around phase transitions within self-organized signals.

Genetic variants, particularly ones found enriched in Indigenous American (IA)-like ancestry and inherited by Hispanics/Latinos, may contribute to this disparity. In this study, we characterized the impact of IA-like ancestry on overall ALL risk and the frequency and effect size of known risk alleles in a large cohort of self-reported Hispanic/Latino individuals.

Introduction: Wound treatment is a significant health burden in any healthcare system, which requires proper management to minimize pain and prevent bacterial infections that can complicate the wound healing process.
Rationale: There is a need to develop innovative therapies to accelerate wound healing cost-effectively. Herein, two polymer-based nanofibrous systems were developed using poly-lactic-co-glycolic-acid (PLGA) and polyvinylpyrrolidone (PVP) loaded with a combination of an antibiotic (Fusidic acid, FA) and a local anesthetic (Lidocaine, LDC) via electrospinning technique for an expedited healing process by preventing bacterial infections while reducing the pain sensation.
