New insight on the acute CCl-induced hepatotoxicity model in rats.

Naunyn Schmiedebergs Arch Pharmacol

January 2025

Center of Studies and Research Toxic-Pharmacological, School of Pharmacy, Federal University of Goias, Leste Universitario, 240th Street, Corner of 5th Avenue, Goiania, GO, 74605-170, Brazil.

The CCl-induced hepatotoxicity model is a traditional preclinical assay applied to evaluate potential hepatoprotective compounds. However, several studies have used it with inappropriate dose and exposure time, generating both weak response or irreversible liver injury, as well as lack of representative liver and plasma biomarkers. Therefore, this study aims to determine the best dose and exposure time of CCl in Wistar rats, permitting a proper evaluation of potential hepatoprotective effect.

Clinical practice guidelines (CPGs) and consensus-based recommendations (CBRs) require considerable effort, collaboration, and time-all within the constraints of finite resources. Professional societies, such as the International League Against Epilepsy (ILAE), must prioritize what topics and questions to address. Implementing evidence-based care remains a crucial challenge in clinical practice.

The photochemical inheritance of Eduardo Lissi and Juan Grotewold and the intersystem crossings with other inheritances.

Photochem Photobiol

January 2025

Departamento de Química, Universidad Nacional de Rio Cuarto, Río Cuarto, Argentina.

In 1963, Eduardo Lissi and Juan Grotewold started a chemical kinetics and photochemistry group at the School of Sciences at the University of Buenos Aires (Facultad de Ciencias Exactas y Naturales, FCEN, UBA). Political circumstances in Argentina and in Chile were a great determinant of the evolution, dispersion, and re-encounters of the group members. The initial graduate students in the group developed their own research groups working in various Countries and on a variety of projects.

is a pathogen that causes sporadic cases and outbreaks of diarrhea. The main virulence feature of this bacterium is the attaching and effacing (AE) lesion formation on infected intestinal epithelial cells, which is characterized by the formation of pedestal-like structures that are rich in F-actin. The Brazilian 1551-2 strain can recruit F-actin using both the Nck-dependent and the Nck-independent pathways, the latter of which uses an adaptor protein named Tir-cytoskeleton coupling protein (TccP/EspF).

Riga-Fede disease (RFD) is a rare, benign condition marked by traumatic ulceration on the tongue's ventral side in infants. It arises from friction between the tongue and lower incisors during sucking, potentially worsening into a keratinized lesion if the cause is not addressed. This report details the case of a 1-year-6-month-old male with hydrocephalus, cleft palate, corpus callosum dysgenesis, neuropsychomotor developmental delay, and tracheostomy and gastrostomy needs.

Potentially paraneoplastic glomerulopathies in a Brazilian cohort: a retrospective analysis.

J Bras Nefrol

January 2025

Universidade Federal de São Paulo (UNIFESP), Departamento de Medicina, Divisão de Nefrologia, São Paulo, SP, Brazil.

Introduction: Glomerular diseases can be associated with solid or hematopoietic malignancies. The prevalence of these associations varies according to the studied glomerular disease. This study aimed to evaluate the frequency and type of neoplasms in patients with glomerular diseases as well as their clinical, laboratory, and histopathological features and the relationship with immunosuppressive therapy.

Introduction: Arteriovenous fistula (AVF) is the preferred vascular access for hemodialysis. Whether acute arm movement impacts arteriovenous fistula (AVF) blood flow is unknown.

Methods: In this cross-sectional analysis, we evaluated AVF blood flow using an ultrasound device at resting and after three muscle movements for proximal (elbow flexion, shoulder adduction and abduction) or distal AVF (fist extension and flexion, fingers squeeze), without and with a 2 kg load.

Introduction: Abdominal aortic aneurysms (AAA) are major causes of morbidity and mortality in the elderly population. Endovascular aneurysm repair (EVAR) is associated with lower complications rates than conventional treatment; however, rigorous follow-up with contrast imaging is required to confirm aneurysmal sac exclusion. The main objective of this study was to quantify and evaluate miRNA expression response to EVAR based on serum dosages at the 6-month follow-up.

Introduction: Tritrpticin (TRP3) is a peptide belonging to the cathelicidin family and has a broad spectrum of antimicrobial activity. However, this class of biomolecules can be easily degraded in the body, making it necessary to use an efficient transport system. The ability to form stable nanostructures from the interaction of glycyrrhizin saponin with the pluronic polymer F127 was demonstrated, forming mixed biopolymeric micelles, highly promising as drug carriers.

Citrate in autosomal dominant polycystic kidney disease: biomarker or therapeutic agent?

Curr Opin Nephrol Hypertens

March 2025

Nephrology Division, Universidade Federal de São Paulo (UNIFESP), São Paulo, Brazil.

Purpose Of Review: This review highlights the latest findings regarding hypocitraturia in autosomal dominant polycystic kidney disease (ADPKD), from both experimental and clinical studies, exploring the underlying pathophysiology and potential therapeutic approach.

Recent Findings: Experimental studies have shown that the lodging of microcrystals in the tubules can trigger cyst formation and growth in polycystic kidney disease (PKD). ADPKD patients are prone to developing hypocitraturia in early stages, which could predispose to calcium microcrystal formation.

The objective of this paper is to discuss the ways in which primitive aspects of the mind, in particular, the archaic elements of character, become manifest within the analytic field. After a review of the concept, it is proposed that a "normal" character manifests through memories in behaviours/feelings, which seek the object to satisfy their needs. The characterological structure keeps primitive traumatic inscriptions under control.

Brazilian Psychoanalytic Society of Rio de Janeiro, Rio de Janeiro, Brazil.

This work seeks to examine two aspects of the passage from the somato-sensory function to the psyche, in an attempt to explore in greater detail the construction of mental representations. The first aspect is the primordial inscription, which ends in the formation of a pictogram. This is an attempt to represent the "thing".

Molecular and functional convergences associated with complex multicellularity in Eukarya.

Mol Biol Evol

January 2025

Laboratório de Algoritmos em Biologia, Departamento de Genética, Ecologia e Evolução, Instituto de Ciências Biológicas, Universidade Federal de Minas Gerais, Brazil.

A key trait of Eukarya is the independent evolution of complex multicellular (CM) in animals, plants, fungi, brown algae and red algae. This phenotype is characterized by the initial exaptation of cell-cell adhesion genes followed by the emergence of mechanisms for cell-cell communication, together with the expansion of transcription factor gene families responsible for cell and tissue identity. The number of cell types (NCT) is commonly used as a quantitative proxy for biological complexity in comparative genomics studies.
