5-Fluorouracil (5-FU) is a chemotherapeutic that is used to treat solid tumors. However, 5-FU is associated with several side effects, including cardiotoxicity. Considering the importance of the intrinsic cardiac nervous system (ICNS) for the heart and that little is known about effects of 5-FU on this nervous system plexus, the purpose of the present study was to evaluate effects 5-FU at a low dose on the ICNS and oxidative and inflammatory effects in the heart in Wistar rats.

In 2017, Kidney Disease: Improving Global Outcomes (KDIGO) published a Clinical Practice Guideline Update for the Diagnosis, Evaluation, Prevention, and Treatment of Chronic Kidney Disease-Mineral and Bone Disorder (CKD-MBD). Since then, new lines of evidence have been published related to evaluating disordered mineral metabolism and bone quality and turnover, identifying and inhibiting vascular calcification, targeting vitamin D levels, and regulating parathyroid hormone. For an in-depth consideration of the new insights, in October 2023, KDIGO held a Controversies Conference on CKD-MBD: Progress and Knowledge Gaps Toward Personalizing Care.

Background: Arginine infusion stimulates copeptin secretion, a surrogate marker of arginine vasopressin (AVP), thereby serving as a diagnostic test in the differential diagnosis of suspected AVP deficiency (AVP-D). Yet, the precise mechanism underlying the stimulatory effect of arginine on the vasopressinergic system remains elusive. Arginine plays a significant role in the urea cycle and increases the production of urea.

In Brazil, health policies implemented over the last three decades have enabled rapid testing for HIV to be made available in primary health care services. However, although these policies are national, the implementation of actions is not uniform, as they depend on the local management of local health systems. In this context, the study identified the proportion of women from sexual minorities who had never tested for HIV and the factors associated with access, in a Metropolitan Region of the Brazilian Amazon.

Methods: Pooled analysis of two Phase III osilodrostat studies (LINC 3 and LINC 4), both comprising a 48-week core phase and an optional open-label extension. Changes from baseline in systolic and diastolic BP (SBP and DBP), fasting plasma glucose (FPG), and glycated hemoglobin (HbA) were evaluated during osilodrostat treatment in patients with/without hypertension or diabetes at baseline.

Epidemiological evidence has shown that the regular ingestion of vegetables and fruits is associated with reduced risk of developing chronic diseases. The introduction of the 3Rs (replacement, reduction, and refinement) principle into animal experiments has led to the use of valid, cost-effective, and efficient alternative and complementary invertebrate animal models which are simpler and lower in the phylogenetic hierarchy.

Mesenchymal stromal cells are multipotent cells present in various tissues that are widely studied for relevant therapeutic potential due to their paracrine immunomodulatory and tissue regenerating properties. Many mesenchymal stromal cell-based products are under investigation for the treatment of different clinical conditions. Recently, the therapeutic potential of the extracellular vesicles released by these cells has been under focus, with emphasis on clinical translation.

The following paper is centred on an analysis of comparative studies of the human pelvis developed over the 19th century by mostly French natural scientists, physical anthropologists, students of the human anatomy and doctors engaged in the initial stages of the emerging fields of gynaecology and obstetrics. As this paper will argue, there was considerable overlap between these specialisations, producing a fundamentally masculine, Eurocentric and racialised knowledge that had an enormous impact in establishing racially informed gynaecological and obstetric practices. This paper argues that comparative pelvic anatomy studies originated from the belief that African and Black women had specifically different pelves and genitalia and served to stratify women of different races and promoted racially oriented obstetric and gynaecological treatments.

Alzheimer's disease (AD) is the leading cause of dementia in the elderly, clinically characterized by memory loss, cognitive decline, and behavioral disturbances. Its pathogenesis is not fully comprehended but involves intracellular depositions of amyloid beta peptide (Aβ) and neurofibrillary tangles of hyperphosphorylated tau. Currently, pharmacological interventions solely slow the progression of symptoms.

Huntington's disease (HD) is an autosomal dominant neurodegenerative disorder characterized by a repeat of the cytosine-adenine-guanine trinucleotide (CAG) in the huntingtin gene (HTT). This results in the translation of a mutant huntingtin (mHTT) protein with an abnormally long polyglutamine (polyQ) repeat. The pathology of HD leads to neuronal cell loss, motor abnormalities, and dementia.
