Complementary Strategies to Identify Differentially Expressed Genes in the Choroid Plexus of Patients with Progressive Multiple Sclerosis.

Neuroinformatics

January 2025

Laboratory for Applied Genomics and Bioinnovations, Instituto Oswaldo Cruz - Fiocruz, Rio de Janeiro, RJ, Brazil.

Multiple sclerosis (MS) is a neurological disease causing myelin and axon damage through inflammatory and autoimmune processes. Despite affecting millions worldwide, understanding its genetic pathways remains limited. The choroid plexus (ChP) has been studied in neurodegenerative processes and diseases like MS due to its dysregulation, yet its role in MS pathophysiology remains unclear.

January 2025

Instituto de Biofísica Carlos Chagas Filho, Universidade Federal do Rio de Janeiro, Rio de Janeiro, Brazil. Electronic address:

The pandemic due to severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) resulted in over 7 million global fatalities and billions of individuals diagnosed with COVID-19. Acute and chronic muscle impairment associated with SARS-CoV-2 infection affected a substantial number of patients, leading to the development of symptoms such as fatigue, muscle pain, and exercise intolerance. Our study introduces an animal model to improve understanding of the pathogenicity caused by SARS-CoV-2 in human skeletal muscle.

Nonlinear Refraction and Absorption in Polymers Used for Femtosecond Direct Laser Writing.

ACS Omega

January 2025

Instituto de Física de São Carlos, Universidade de São Paulo, São Carlos, SP 13560-970, Brasil.

Direct laser writing (DLW) has been recognized as a unique technique for three-dimensional (3D) prototyping with resolution beyond the diffraction limit. One trend in DLW technologies is the use of polymers, given their favorable mechanical properties and optical quality, rendering them promising for the next generation of nonlinear photonic devices. However, absorptive properties that facilitate DLW processes may also hinder the performance of polymers as all-optical devices.

Pharmacotherapy in Alcohol Withdrawal Syndrome (AWS), which is a mental disorder, generally involves benzodiazepines due to their action via GABA, but their side effects, such as excessive sedation, mental confusion and risk of dependence, are considerable. It is important to investigate the anxiolytic potential of plants such as Caryocar coriaceum, due to the presence of secondary metabolic compounds, such as isoquercitrin, capable of promoting the reduction of anxiety during AWS. We evaluated the anxiolytic-like potential of ethanolic extracts from the leaves (EEPL) and pulp (EEPP) of C.

A voltammetric method for determining N-nitrosodimethylamine in losartan and olmesartan drugs.

J Pharm Sci

January 2025

Universidade Federal da Paraíba, Departamento de Química, 58051-970, João Pessoa, Paraíba, Brasil. Electronic address:

Recently, the National Health Surveillance Agency (ANVISA) of Brazil recalled several lots of sartan drugs due to the presence of N-nitrosodimethylamine (NDMA). NDMA is a highly potent carcinogenic contaminant that harms human health; therefore, the presence of NDMA in sartan drugs must be checked through appropriate analytical methods. This work successfully developed a new analytical method for determining NDMA without chemical pretreatment of losartan and olmesartan drug samples.

Yellow fever (YF) is a viral disease that affects both humans and non-human primates (NHPs). Neotropical monkeys are more severely stricken by YF and the impact of the disease can be devastating to the endangered golden-headed lion tamarins (GHLTs, Leontopithecus chrysomelas). Susceptible GHLTs were immunized with the commercial Brazilian YF 17DD live attenuated vaccine or two other experimental non-replicating YF vaccines: a purified whole-virus, b-propiolactone-inactivated vaccine and a plant-derived recombinant subunit vaccine.

This study aimed to identify splicing quantitative trait loci (cis-sQTL) in Nelore cattle muscle tissue and explore the involvement of spliced genes (sGenes) in immune system-related biological processes. Genotypic data from 80 intact male Nelore cattle were obtained using SNP-Chip technology, while RNA-Seq analysis was performed to measure gene expression levels, enabling the integration of genomic and transcriptomic datasets. The normalized expression levels of spliced transcripts were associated with single nucleotide polymorphisms (SNPs) through an analysis of variance using an additive linear model with the MatrixEQTL package.
