Do hairdressers comprise a high risk group for genotoxicity? A systematic review.

Background And Objectives: Nowadays, hair dye products are widely used for aesthetic purposes, in which it generates chemical exposure to customers and, mainly, hairdressers. The aim of this systematic review was designed to elucidate the following question: are hair dye products able to induce DNA damage in hairdressers?

Methods: Studies were included in our analyses if they met the following criteria: (1) studies measuring genetic damage in vivo; (2) studies published in English; (3) studies that provided data clearly presented in scientific standards.

Results: Full manuscripts from 13 studies were carefully selected in this setting.

Is micronucleus assay in nasal mucosa cells an appropriate technique for detecting genotoxins by inhalation in humans? A systematic review.

This study aimed to evaluate the scientific literature on the micronucleus assay in nasal mucosa as an appropriate method for evaluating genotoxicity caused by chemical agents. According to the PRISMA guidelines, only in vivo human studies with micronucleus assays using nasal cells were considered. Reviews, case reports, editorials, letters to the editor, and articles not written in English were excluded.

Degenerative changes induced by paradoxical sleep deprivation in rat sublingual glands.

Purpose: The aim of this study was to evaluate whether sleep deprivation can induce degenerative changes in rat sublingual glands.

Methods: For this purpose, a total of 24 males were distributed into three groups: control (n = 8), in which the animals were not subjected to any procedure; sleep deprivation (n = 8) in which the animals were submitted to sleep deprivation for 96 h; recovery (n = 8), in which the animals were subjected to paradoxical sleep deprivation for 96 consecutive hours followed by 96 h without intervention. Morphological changes in sublingual glands as well as the immunoexpressions of some proteins, such as Ki-67, p16, cleaved caspase-3 and BCL-2 were investigated in this setting.

Domestic violence against women during the Covid-19 pandemic: A scoping review.

Objectives: This scoping review aims to assess the situation of violence against women during the COVID-19 pandemic in Latin America, mainly in Brazil.

Methods: This study consists of a Scoping Review based on the (PRISMA) statement. To conduct this review, we mapped scientific evidence on domestic violence during the COVID-19 pandemic.

Technique for Obtaining Mesenchymal Stem Cell from Adipose Tissue and Stromal Vascular Fraction Characterization in Long-Term Cryopreservation.

Human mesenchymal stem cells derived from adipose tissue have become increasingly attractive as they show appropriate features and are an accessible source for regenerative clinical applications. Different protocols have been used to obtain adipose-derived stem cells. This article describes different steps of an improved time-saving protocol to obtain a more significant amount of ADSC, showing how to cryopreserve and thaw ADSC to obtain viable cells for culture expansion.

Resveratrol effects in oral cancer cells: a comprehensive review.

Oral cancer is a very common tumor worldwide with high incidence and mortality. The treatment of oral cancer involves surgery, radio- and chemotherapy; however, high failure rates and toxicity are noticed. Thus, the search of new drugs aiming a more effective treatment is welcomed.
