Acute cannabidiol treatment reverses behavioral impairments induced by embryonic valproic acid exposure in male mice.

Cannabidiol (CBD), the major non-psychotomimetic compound of the Cannabis sativa plant, has shown promising effects in addressing various symptoms associated with autism spectrum disorder (ASD). This neurodevelopmental disorder typically impacts cognitive, behavioral, social communication, and motor skills domains. However, effective treatments for the wide range of symptoms associated with the disorder are limited and may trigger undesirable effects.

A Nutritional Strategy Based on Multiple Components for Glycemic Control in Type 2 Diabetes: A Multicenter Randomized Controlled Clinical Trial.

Background/objectives: The optimal dietary approach for managing glycemic and metabolic control in type 2 diabetes (T2D) is still uncertain, though it should be tailored for clinical settings. Therefore, we sought to assess the impact of a multicomponent nutritional strategy on glycemic control in T2D patients within a public health system.

Methods: NUGLIC was an open-label, parallel-group, superiority, multicenter randomized controlled trial.

The Impact of the COVID-19 Pandemic: A Longitudinal Analysis of Body Weight Variations and Their Implications for Daily Habits.

Assessing changes in lifestyle, dietary habits, eating behaviors, and stress during the pandemic and their impact on weight is crucial for developing effective interventions. This study investigated weight variations among Brazilians and associated habit changes over nine months during the COVID-19 pandemic. An online questionnaire was applied (T0/T1, T2).

The acute effects of coffee ingestion on postural control and physical function in older adults: A randomised crossover trial.

Caffeine consumption can elicit improvements in aspects of physical function in older adults but also, negatively modify standing balance, potentially increasing fall risk. However, balance alterations and changes in physical function induced by commonly consumed caffeine vehicles such as coffee have not been investigated. Therefore, this study investigated coffee ingestion providing 3 mg·kg BW caffeine on balance performance and physical function, in a group of older adults.

Objective: This study aimed to evaluate inflammatory biomarkers in patients undergoing peritoneal dialysis and investigate their association with all-cause mortality or transfer to hemodialysis.

Methods: This prospective cohort study included 43 patients undergoing peritoneal dialysis. Plasma levels of cytokines were measured using flow cytometry and capture enzyme-linked immunosorbent assay.

Generation of a homozygous (MCRIi031-A-3) WT1 knockout human iPSC line.

The transcription factor WT1 plays a critical role in several embryonic developmental processes such as gonadogenesis, nephrogenesis, and cardiac development. We generated a homozygous (MCRIi031-A-3) WT1 knockout induced pluripotent stem cell (iPSC) line from human fibroblasts using a one-step protocol for CRISPR/Cas9 gene-editing and episomal-based reprogramming. The cells exhibit a normal karyotype and morphology, express pluripotency markers, and have the capacity to differentiate into the three embryonic germ layers.

Mid-arm muscle circumference cutoff points in patients with cirrhosis: Low muscle mass related to malnutrition predicts mortality.

Objectives: Muscle loss is one of the phenotypic criteria of malnutrition, is highly prevalent in patients with cirrhosis, and is associated with adverse outcomes. Mid-arm muscle circumference (MAMC) estimates the skeletal muscle mass and is especially helpful in cases of fluid overload. This study aimed to propose MAMC cutoff points for patients with cirrhosis and demonstrate its association with 1-year mortality.

Toxic tasting: how capuchin monkeys avoid grasshoppers' chemical defenses.

Platyrrhines consume many species of arthropods in the order Orthoptera. Some species of orthopterans can produce chemical defenses that render them toxic or unpalatable and thus act as predator deterrents. These species include the stick grasshoppers (family Proscopiidae), which are widely distributed in the Caatinga biome in northeastern Brazil, which comprises part of the distribution of capuchin monkeys.

Effect of exercise detraining in cognitive functions of older adults: A systematic review.

Objective: Provide a synthesis of the current literature about the effects of detraining on cognitive functions in older adults.

Methods: The PICOS acronym strategy was performed in PubMed/MEDLINE, Web of Science, Cochrane Library and PsycINFO database. The Preferred Reporting Items for Systematic Review and Meta-Analyses statement had been followed in the present study, in which the search was conducted on October 2023.

Generation of heterozygous (MCRIi030-A-1) and homozygous (MCRIi030-A-2) NR2F2/COUP-TFII knockout human iPSC lines.

The NR2F2 gene encodes the transcription factor COUP-TFII, which is upregulated in embryonic mesoderm. Heterozygous variants in NR2F2 cause a spectrum of congenital anomalies including cardiac and gonadal phenotypes. We generated heterozygous (MCRIi030-A-1) and homozygous (MCRIi030-A-2) NR2F2-knockout induced pluripotent stem cell (iPSC) lines from human fibroblasts using a one-step protocol for CRISPR/Cas9 gene-editing and episomal-based reprogramming.

Livestock intensification and environmental sustainability: An analysis based on pasture management scenarios in the brazilian savanna.

Brazil's major beef production occurs in the Cerrado, predominantly as extensive pastures that covers ∼50 Mha of the biome, of which approximately 2/3 show signs of degradation. Pasture recovery is now a key environmental policy, as it improves land use efficiency and soil carbon sequestration. However, as intensification leads to higher cattle stocking rates and external inputs (fertilizers, liming, etc.

Mindful eating questionnaire: Validation and reliability in Brazilian adults with type 2 diabetes mellitus.

Objective: The objective was to evaluate the psychometric properties of the Mindful Eating Questionnaire (MEQ) in Brazilian subjects with type 2 diabetes mellitus (T2DM) and validate a Brazilian version of the MEQ for adults with T2DM (MEQ-DM).

Methodology: Baseline data from the multicentre Nutritional Strategy for Glycaemic Control in Patients with Type 2 Diabetes Mellitus (NUGLIC) trial were used. Construct validity was assessed using exploratory factor analysis (EFA).

COUP-TFII regulates early bipotential gonad signaling and commitment to ovarian progenitors.

Background: The absence of expression of the Y-chromosome linked testis-determining gene SRY in early supporting gonadal cells (ESGC) leads bipotential gonads into ovarian development. However, genetic variants in NR2F2, encoding three isoforms of the transcription factor COUP-TFII, represent a novel cause of SRY-negative 46,XX testicular/ovotesticular differences of sex development (T/OT-DSD). Thus, we hypothesized that COUP-TFII is part of the ovarian developmental network.

Identification of IPT9 in Brachiaria brizantha (syn. Urochloa brizantha) and expression analyses during ovule development in sexual and apomictic plants.

Background: In Brachiaria sexual reproduction, during ovule development, a nucellar cell differentiates into a megaspore mother cell (MMC) that, through meiosis and mitosis, gives rise to a reduced embryo sac. In aposporic apomictic Brachiaria, next to the MMC, other nucellar cells differentiate into aposporic initials that enter mitosis directly forming an unreduced embryo sac. The IPT (isopentenyltransferase) family comprises key genes in the cytokinin (CK) pathway which are expressed in Arabidopsis during ovule development.

The Mini Nutritional Assessment-Short Form is more effective in predicting clinical outcomes among hospitalised patients with overweight than the Nutritional Risk Screening-2002.

Understanding of the association between nutritional risk and clinical outcomes in hospitalised patients with overweight is still at an early stage. Given the lack of specific tools for the patient with overweight, the objective of this study was to compare two of the main general screening instruments for assessing nutritional risk in predicting clinical outcomes in a population of hospitalised patients with overweight. A retrospective study was carried out in a medium-sized hospital in Brazil, with patients ≥20 years old admitted between July 2017 and December 2019.

Contrast phase recognition in liver computer tomography using deep learning.

Hepatocellular carcinoma (HCC) has become the 4th leading cause of cancer-related deaths, with high social, economical and health implications. Imaging techniques such as multiphase computed tomography (CT) have been successfully used for diagnosis of liver tumors such as HCC in a feasible and accurate way and its interpretation relies mainly on comparing the appearance of the lesions in the different contrast phases of the exam. Recently, some researchers have been dedicated to the development of tools based on machine learning (ML) algorithms, especially by deep learning techniques, to improve the diagnosis of liver lesions in imaging exams.
