Expert perspectives on tuberculosis screening procedures for migrants.

Objective: To evaluate the perspectives of tuberculosis experts from different countries regarding national screening procedures.

Methods: This was a qualitative descriptive study. Data were collected by using electronic, anonymized surveys with experts in tuberculosis in seven different countries within two World Health Organization regions (Europe and Africa).

Challenges in determining the global burden of non-malignant central nervous system tumors: an analysis of international incidence and mortality data sources.

Background: Non-malignant tumors of the CNS contribute substantially to the morbidity and mortality from CNS tumors. It is critical to understand the epidemiology of non-malignant CNS tumors separately from CNS malignancies to inform resource allocation and policy since treatment and prognosis can differ. High quality international data on non-malignant CNS tumor burden are needed to accomplish this goal.

Novel Tryptophyllin Peptides from Physalaemus centralis Inhibit Oxidative Stress-Induced Endothelial Dysfunction in Rat Aorta Preparation.

Amphibian skin is a rich source of molecules with biotechnological potential, including the tryptophyllin family of peptides. Here, we report the identification and characterization of two tryptophyllin peptides, FPPEWISR and FPWLLS-NH, from the skin of the Central Dwarf Frog, Physalaemus centralis. These peptides were identified through cDNA cloning and sequence comparison.

Effects of Animal-Assisted Therapy for Anxiety Reduction in Children and Adolescents: A Systematic Review.

: Animal-Assisted Therapy (AAT) is a clinical approach aimed at building valuable human-animal relationships with both preventive and therapeutic goals. It is provided by a healthcare professional and involves animals (meeting certain criteria) as an integral part of the treatment process. This type of therapy has been shown to have multiple benefits in several areas, such as reducing anxiety in a variety of different groups of people.

A novel bombesin-related peptide modulates glucose tolerance and insulin secretion in non-obese and hypothalamic-obese rats.

This study investigated the effects of a novel bombesin-related peptide (BR-b), derived from the skin of the Chaco tree frog (Boana raniceps), on glucose homeostasis in non-obese and hypothalamic-obese male rats. Hypothalamic obesity was induced in neonatal rats through high-dose administration of monosodium glutamate (MSG; 4 g/kg), while control animals (CTL) received an equimolar saline solution. At 70 days of age, both MSG and CTL groups underwent an oral glucose tolerance test (OGTT; 2 g/kg) with or without prior intraperitoneal administration of BR-b at doses of 0.
