Urban pests pose enormous risks to human health. Control initiatives are carried out in regions of high infestation and incidence of accidents caused by scorpions OBJECTIVE In this study, we aimed to analyze the anti-scorpionic activity of fungal isolates obtained from a cemetery in Brazil. A total of thirteen fungi were subjected to a bioassay test against Tityus serrulatus, and the two isolates with the highest scorpionicidal activity were selected for molecular identification through sequencing of the ITS DNA hypervariable region and large-scale cultivation on liquid medium for secondary metabolite extraction. The crude extracts were partitioned by solid-phase extraction, and the resulting purified extracts were tested for anti-scorpionic activity. The extracts from one of the isolates presented better results and were submitted to UPLC-MS/MS. The metabolomics data were submitted to GNPS website for Molecular Networking and MASST searches. We also performed a MolNetEnhancer analysis to identify the chehat has great potential for isolation of secondary metabolites.Antioxidant defense is essential for animals to cope with homeostasis disruption during hibernation. The present study aimed to investigate the antioxidant defense response of juvenile soft-shelled turtle Pelodiscus sinensis during hibernation and following arousal. Turtle brain, liver, and kidney samples were collected at pre-hibernation (17 °C mud temperature; MT), during hibernation (5.8 °C MT) and after arousal (20.1 °C MT) in the field. Transcript levels of NF-E2-related factor 2 (Nrf2) decreased significantly during hibernation and recovered after arousal in all tissues. Cerebral and nephric copper-zinc superoxide dismutase (Cu/Zn SOD), catalase (CAT), glutathione peroxidase 3 (GPx3) and nephric GPx4 mRNA showed similar changing patterns as Nrf2. Cerebral Mn SOD, GPx1 and nephric GPx1 up-regulated after arousal. Hepatic Cu/Zn SOD, GPx1 and GPx3 mRNA kept stable, except hepatic GPx4 increased during hibernation. Hepatic Mn SOD and CAT increased after arousal. In the GSH system, mRNA levels of glutathione synthetases (GSs) kept stable during hibernation and up-regulated after arousal in most tissues except nephric GS2 mRNA remained unchanged. Gene expressions of glutathione reductase (GR) exhibited a tissue specific changing pattern, while those of glutathione-S-Transferase (GST) shared a similar pattern among tissues remained stable or down-regulated during hibernation then recovered in arousal. In contrast to these diverse responses in gene expressions, most of the antioxidant enzyme activities maintained high and stable. selleck products Overall, no preparation for oxidative stress (POS) strategy was found in enzymatic antioxidant system in P. sinensis juveniles during hibernation, the Chinese soft-shelled turtles were able to stay safe from potential oxidative stress during hibernation by maintaining high level activities/concentrations of the antioxidant enzymes/antioxidants. We investigated factors influencing pre-biopsy prostate-specific antigen (PSA) retesting as recommended by clinical guidelines. 333 patients screened for prostate cancer (PCa) repeated PSA (Roche Cobas systems) after a median of 3.9months, before performing biopsy. Multiple regression models were used to assess effects of patients' characteristics on PSA results and changes over time. PCa [n=132 (40.7%)] and cancer-free [n=192 (59.3%)] patients had similar rate of PSA positive results at baseline (84.8% vs. 83.9%, P=0.931). Their rate of reversion to normal PSA after retesting was negligible (0.9% in PCa and 3.7% in PCa-free patients, P=0.286). 31.1% of PCa and 31.3% of cancer-free patients (P=0.426) showed a significant PSA increase after retesting. Age was a confounder since not only PSA increased in older PCa patients, but it was also related to PCa histological grade, in turn associated to PSA increase. In PCa-free patients, glandular inflammation, present in 1/3 of subjects, was also associated to higher PSA concentrations. When obtained with the same immunoassay under controlled analytical conditions, a PSA positive result is confirmed after retesting in the great majority of screened patients. Neither analytical factors nor intraindividual variability appeared to justify PSA retesting before biopsy referral.When obtained with the same immunoassay under controlled analytical conditions, a PSA positive result is confirmed after retesting in the great majority of screened patients.

The medical management of patients, which involves securing the drug circuit, is a major public health objective. As part of quality management, a number of risk assessment and risk management tools in care units are validated and available. However, medication management in radiopharmacy departments represents a complex and specific process. The aim of the "Quality guidelines for radiopharmacy" working group of the French society of radiopharmacy (SoFRa) was to develop a risk-assessment tool that is a priori adapted to radiopharmacy activity. A qualitative risk matrix was developed, based on available analysis tools and current regulations concerning radiopharmacy practice. The tool was then programmed to obtain a summary and scoring for each risk category, as well as a quantitative analysis of the risks identified in radiopharmacy. Our tool contains 262 issues. The qualitative study integrates the risks related to the circuit of radiopharmaceuticals, but also risks related to personnel. The quantitative study makes it possible to carry out an automated analysis of the actions to carry out in priority to improve the practices. This work led to the development of a self-assessment tool for the a priori analysis of risks that are adapted to the practice of radiopharmacy. It allows easy analysis of the entire circuit of radiopharmaceuticals from a single tool and meet the expectations of health authorities. This common and validated tool is available to the pharmaceutical community.This work led to the development of a self-assessment tool for the a priori analysis of risks that are adapted to the practice of radiopharmacy.
