Crack cocaine is a highly toxic drug with great potential to induce addiction. It produces more intense effects than cocaine powder, with its use having grown worldwide. However, few studies have focused on the cognitive and biochemical consequences that result from crack cocaine inhalation. This study examined the effects of direct crack cocaine inhalation on spatial working memory and brain oxidative stress parameters in rats. Male adult Wistar rats, well-trained in an eight-arm radial maze (8-RM), underwent five sessions of crack cocaine inhalation (crack cocaine group) once a day or inhalation simulation (sham group), being tested in 1-h delayed tasks 24 h after the last inhalation...

This study investigated the association of six different anthropometric markers with metabolic syndrome to find the most suited to predict children at risk. Sample comprises 1324 Portuguese youth (701 girls, 623 boys), aged 10-17 years. Six anthropometric markers were included: body mass index (BMI), BMI z-score, tri-ponderal index (TPI), waist circumference (WC), WC/height ratio (WC/H), and WC/H adjusted ratio (WC/Hadj ). A standardized metabolic risk score (zMR) was computed by summing of standardized values for fasting glucose, triglycerides, high density lipoprotein cholesterol, and mean arterial blood pressure...

INTRODUCTION: Detection of Strongyloides stercoralis larvae is particularly challenging because only a small number of larvae are released into the feces, regardless of infection stage. OBJECTIVE: Our objective was to apply conventional polymerase chain reaction (PCR) to the detection of S. stercoralis DNA in feces samples to evaluate its performance in samples of patients with strongyloidiasis and compare results with those of immunodiagnosis. METHODS: Stool, serum, and saliva samples were collected from each individual (n = 48) at the clinic hospital of the State University of Londrina, Brazil, for parasitological, immunological, and molecular tests...

The purpose of this study was to evaluate whether exposure to particles induces an imbalance in 70-kDa heat shock proteins (HSP70). Since intracellularly (iHSP70) it has anti-inflammatory roles whereas extracellularly (eHSP70) it has pro-inflammatory roles, we evaluate the effect of residual oil fly ash (ROFA) exposure on eHSP70-to-iHSP70 ratio (H index), a biomarker of inflammatory status that is related to oxidative stress in plasma and lymphoid tissue. Wistar rats that received ROFA suspension for three consecutive days (750 μg) showed an increase in plasma eHSP70 levels (mainly the 72-kDa inducible form)...

Ovarian cancer is the second most common gynaecologic malignancy and the main cause of death from gynaecologic cancer, due to late diagnosis and chemoresistance. Studies have reported the role of cysteine in cancer, by contributing for hydrogen sulphide (H2 S) generation and as a precursor of glutathione (GSH). However, the role of cysteine in the adaptation to hypoxia and therapy response remains unclear. We used several ovarian cancer cell lines, ES2, OVCAR3, OVCAR8, A2780 and A2780cisR, to clarify cysteine relevance in ovarian cancer cells survival upon hypoxia and carboplatin...

The magnetic targeting (MT) technique improves delivery of mesenchymal stromal cells (MSCs) to target sites. However, the moderate-intensity static magnetic fields (SMF) used for MT may exert adverse effects on MSCs. Thus, we aimed to evaluate the effects of SMF on MSCs in vitro. Cells were initially magnetized using citrate-coated magnetite nanoparticles. Then, control and magnetized MSCs were transferred to an in vitro MT system and exposed to 0.3-0.45 Tesla SMFs. MSC viability, morphology, ultrastructure, proliferation rates, differentiation, and immunomodulation were evaluated after 24 and 48hours of exposure...

Breast Cancer (BC) is a highly heterogeneous disease whose most aggressive behavior is displayed by triple-negative breast cancer (TNBC), which lacks an efficient targeted therapy. Despite its controversial role, one of the proteins that having been linked with BC is Annexin A1 (AnxA1), which is a Ca+2 binding protein that acts modulating the immune system, cell membrane organization and vesicular trafficking. In this work we analyzed tissue microarrays of BC samples and observed a higher expression of AnxA1 in TNBCs and in lymph node metastasis...

Sepsis is one of the main causes of hospitalization and mortality in Intensive Care Units. One of the first manifestations of sepsis is encephalopathy, reported in up to 70% of patients, being associated with higher mortality and morbidity. The factors that cause sepsis-associated encephalopathy (SAE) are still not well known, and may be multifactorial, as perfusion changes, neuroinflammation, oxidative stress and glycolytic metabolism alterations. Fructose-1,6-bisphosphate (FBP), a metabolite of the glycolytic route, has been reported as neuroprotective agent...

Some groups have avoided early microsurgical flaps in electrical burns under the pretext of injury to the microvasculature, which could increase vascular thrombosis. However, this option frequently results in amputation of the extremity. This study aims to evaluate the early application of microsurgical flaps for the treatment of electrical burns of extremities. A case series was retrospectively evaluated including patients with electrical trauma in extremities undergoing early microsurgical reconstruction...

Polymicrobial infections with mixed-species biofilms are important health problems because of increased antimicrobial resistance and worse patient outcomes than with monomicrobial infections. Here, we present the whole-genome sequence of Staphylococcus epidermidis strain GTH12, which was cocultured with the yeast Candida albicans SC5314 (generating C. albicans strain SC5314 GTH12), thus providing genomic information on polymicrobial infections.

Keutel syndrome is caused by mutations in the matrix gamma-carboxyglutamic acid ( MGP ) gene (OMIM 154870) and is inherited in an autosomal recessive fashion. It is characterized by brachydactyly, pulmonary artery stenosis, a distinctive facial phenotype, and cartilage calcification. To date, only 36 cases have been reported worldwide. We describe clinical and molecular findings of the first Brazilian patient with Keutel syndrome. Keutel syndrome was suspected based on clinical and morphological evaluation, so we sequenced the MGP gene using the TruSight One Sequencing Panel (Illumina)...

The envelope glycoprotein 51 (gp51) is essential for bovine leukaemia virus (BLV) entry to bovine B-lymphocytes. Although the bovine adaptor protein 3 complex subunit delta-1 (boAP3D1) has been proposed as the potential receptor, the specific ligand-receptor interaction has not yet been completely defined and boAP3D1 receptor and gp51 3D structures have not been determined. This study was thus aimed at a functional annotation of boAP3D1 cellular adaptor protein and BLV gp51 and, proposing a reliable model for gp51-AP3D1 interaction using bioinformatics tools...
