Generational Differences in Self-Esteem and Vocal Perception Among Brazilian Gay Men.

J Voice

January 2025

Speech-Language Pathology Department, Universidade Federal de São Paulo - UNIFESP, Rua Botucatu, 802 Vila Clementino, 04023-062, São Paulo, São Paulo, Brazil. Electronic address:

Introduction: Self-esteem and vocal perception are central aspects of identity and self-presentation, particularly within marginalized communities where voice and self-concept can be deeply intertwined with social acceptance and cultural dynamics. Among Brazilian gay men, generational differences in these areas may reflect broader social changes, shifts in stigma, and evolving notions of masculinity. This study aims to explore these differences, examining how self-esteem and self-assessed vocal descriptions vary across generations, thereby shedding light on specific needs and areas for potential support within these communities.

Cry proteins, commonly found in gram-positive soil bacteria, are used worldwide as aerial sprays or in transgenic plants for controlling crop pest populations and as insect vectors. Via PCR analysis, a spore producing soil isolate (BV5) was speculated to encode a Cry gene. Partial nucleotide sequence of the amplified PCR fragment showed homology with the Cry8 genes present in GenBank.

Magnetic nanoparticles (MNPs) used for magnetic hyperthermia can not only damage tumor cells after elevating to a specific temperature but also provide the temperature required for thermosensitive liposomes (TSL) to release doxorubicin (DOX). MNPs injected into tumor will generate heat under an alternating magnetic field, so the MNPs distribution can determine temperature distribution and further affect the DOX concentration used for tumor therapy. This study proposes an asynchronous injection strategy for this combination therapy in order to improve the DOX concentration value for drug therapy, in which the MNPs are injected into tumor after a certain lagging of TSL injection in order to increase the TSL concentration inside tumor.

Background: Sarcopenia is associated with clinical complications that increase mortality in older adults. Current screening tools, such as Sarc-F and Sarc-CalF, focus primarily on muscular performance but have limited sensitivity in identifying elderly individuals at risk of sarcopenia. The present study aims to develop a more comprehensive sarcopenia risk screening tool, Sarc-Global, which integrates additional anthropometric and clinical variables to enhance the sensitivity and accuracy of sarcopenia risk assessment in older adults.

This study investigated the effects of chitosan/gelatin (CG) coatings containing pomegranate peel extract (PPE) on the physical-chemical, microbiological, volatile profile, and sensory characteristics of strawberries over 12 days of refrigerated storage. The coatings containing PPE minimized the weight loss of the fruits by 11 % and delayed their fungal contamination by 6-8 days. Uncoated fruits showed soluble solids content, pH, and titratable acidity values characteristics of highly deteriorated fruits.

Purpose: This investigation was conducted to elucidate the effects of eugenol on bladder contractility through experimental and in silico approaches.

Methods: To assess the impact of eugenol on muscular contractility, longitudinal strips of bladder tissue, measuring 2 mm by 6 mm, were mounted in perfusion chambers connected to an isometric force transducer. Furthermore, molecular docking studies were conducted to explore the potential of eugenol to target the M3 muscarinic acetylcholine receptor (M3R) and voltage-operated calcium channels (VOCCs) in muscle cells, utilizing in silico techniques.

No evidence that breast cancer occurs at higher rates among young Arab women.

East Mediterr Health J

December 2024

Department of Radiology, King Abdulaziz University, Jeddah, Saudi Arabia.

Article Synopsis
  • The study investigates breast cancer incidence rates among Arab women compared to women from high- and middle-income countries, focusing on age-specific data.
  • Findings reveal that young Arab women have breast cancer rates that are comparable to or lower than those in selected high- and middle-income countries, contradicting the perception of higher risk in this demographic.
  • The results suggest that the higher number of cases in Arab countries may be attributed to a younger population structure, emphasizing the need for updated breast cancer screening policies in the region.

Annually, thousands of individuals suffer from skin injuries resulting from trauma, surgeries, or diabetes. Inadequate wound treatment can delay healing and increase the risk of severe infections. In this context, a promising synthetic polymer with potent antimicrobial properties, Poly{2-[(methacryloyloxy)ethyl]trimethylammonium chloride} (PMETAC), is synthesized and crosslinked with N,N'-Methylenebis(acrylamide) (BIS) in the presence of Chitosan (CH), a natural, biocompatible polysaccharide that promotes cell regeneration and provides additional beneficial properties.
