Cannabidiol partially rescues behavioral, neuroinflammatory and endocannabinoid dysfunctions stemming from maternal obesity in the adult offspring.

Maternal obesity is known to increase the risk of psychiatric disorders, such as anxiety, depression, schizophrenia and autism spectrum disorder in the offspring. While preventive measures are well-documented, practical approaches for addressing the damages once they are already established are limited. We have recently demonstrated the interplay between maternal obesity and treatment with cannabidiol (CBD) on neuroinflammation and peripheral metabolic disturbances during adolescence, however, it is known that both factors tend to vary throughout life.

Cannabidiol treatment improves metabolic profile and decreases hypothalamic inflammation caused by maternal obesity.

Introduction: The implications of maternal overnutrition on offspring metabolic and neuroimmune development are well-known. Increasing evidence now suggests that maternal obesity and poor dietary habits during pregnancy and lactation can increase the risk of central and peripheral metabolic dysregulation in the offspring, but the mechanisms are not sufficiently established. Furthermore, despite many studies addressing preventive measures targeted at the mother, very few propose practical approaches to treat the damages when they are already installed.

The first baseline of ALDFG generated by the artisanal fishery during the SARS-CoV-2 pandemic on the north coast of Pernambuco, Brazil.

To prevent the spread of the COVID-19 contagion, some regions of Brazil implemented a prohibition of beach use, which contributed to a reduction of artisanal fishing activity. This study aimed to evaluate the influence of these beach closures on the incidence of abandoned, lost, or discarded fishing gear (ALDFG) along four beaches located on the northern coast of Pernambuco, Brazil. The absolute and relative frequency of occurrence and the number of observations per unit of effort (OPUE) between the periods before and after the prohibition period were analyzed.

Evaluation of Promega PowerSeq™ Auto/Y systems prototype on an admixed sample of Rio de Janeiro, Brazil: Population data, sensitivity, stutter and mixture studies.

Forensic DNA typing typically relies on the length-based (LB) separation of PCR products containing short tandem repeat loci (STRs). Massively parallel sequencing (MPS) elucidates an additional level of STR motif and flanking region variation. Also, MPS enables simultaneous analysis of different marker-types - autosomal STRs, SNPs for lineage and identification purposes, reducing both the amount of sample used and the turn-around-time of analysis.

pH interferes in photoinhibitory activity of curcumin nanoencapsulated with pluronic® P123 against Staphylococcus aureus.

Microbial contamination control is a public health concern and challenge for the food industry. Antimicrobial technologies employing natural agents may be useful in the food industry for these purposes. This work aimed to investigate the effect of photodynamic inactivation using curcumin in Pluronic® P123 nanoparticles (Cur/P123) at different pH and blue LED light against Staphylococcus aureus.

Evaluation of 16S rRNA Hypervariable Regions for Bioweapon Species Detection by Massively Parallel Sequencing.

Molecular detection and classification of the bacterial groups in a sample are relevant in several areas, including medical research and forensics. Sanger sequencing of the 16S rRNA gene is considered the gold standard for microbial phylogenetic analysis. However, the development of massively parallel sequencing (MPS) offers enhanced sensitivity and specificity for microbiological analyses.

Hypericin-mediated photoinactivation of polymeric nanoparticles against Staphylococcus aureus.

Photoinactivation is a promising technique for Staphylococcus aureus control. This microorganism causes foodborne diseases (DTAs) and forms biofilms that are highly resistant and difficult to eradicate. Thus, the aim of this study was to evaluate the photodynamic activity of hypericin (HYP) in polymeric nanoparticles (Pluronic® P123) against S.

Quality of life may be a more valuable prognostic factor than depression in older hemodialysis patients.

Purpose: Depression and impairment of quality of life (QoL) reduce the survival of individual on hemodialysis (HD). However, few studies evaluated the impact of these conditions on the survival of older patients undergoing HD.

Methods: A retrospective cohort study was performed including patients aged ≥ 60 years on HD in Recife, Brazil, assessed in 2013 and monitored until 2017.

Depression and quality of life in older adults on hemodialysis.

Objective: Depression is highly prevalent in hemodialysis patients, but few studies have evaluated older hemodialysis patients. The aim of this study was to evaluate the prevalence of depression, its associated factors and its impact on quality of life in an older population on hemodialysis.

Methods: This was a cross-sectional study including 173 hemodialysis patients aged 60 years or older in Recife, Brazil.

Microbial enrichment and gene functional categories revealed on the walls of a spent fuel pool of a nuclear power plant.

Microorganisms developing in the liner of the spent fuel pool (SFP) and the fuel transfer channel (FTC) of a Nuclear Power Plant (NPP) can form high radiation resistant biofilms and cause corrosion. Due to difficulties and limitations to obtain large samples from SFP and FTC, cotton swabs were used to collect the biofilm from the wall of these installations. Molecular characterization was performed using massively parallel sequencing to obtain a taxonomic and functional gene classification.

Contrasting the microbiomes from forest rhizosphere and deeper bulk soil from an Amazon rainforest reserve.

Pristine forest ecosystems provide a unique perspective for the study of plant-associated microbiota since they host a great microbial diversity. Although the Amazon forest is one of the hotspots of biodiversity around the world, few metagenomic studies described its microbial community diversity thus far. Understanding the environmental factors that can cause shifts in microbial profiles is key to improving soil health and biogeochemical cycles.

Individual-based model of Chironomus riparius population dynamics over several generations to explore adaptation following exposure to uranium-spiked sediments.

Natural populations are chronically exposed to various pollutants over many generations. It is thus crucial to understand and quantify adaptive dynamics of stressed populations in order to increase the relevance of ecotoxicological risk assessment. However, long-term consequences to population exposure are not much studied yet.

Exposure of Chironomus riparius larvae to uranium: effects on survival, development time, growth, and mouthpart deformities.

Among non-biologically essential metals, data concerning uranium effects on freshwater benthic macroinvertebrates are scarce. The effects of uranium on survival, development time, growth and mouthpart deformities of midge Chironomus riparius were investigated. A 10-day static laboratory bioassay was performed exposing first instar larvae to artificial sediment spiked with four concentrations of uranium (2.
