Objective To increase the understanding of women who experience negative effects on sexual function when using hormonal contraception.Methods We performed 24 in-depth interviews with women who had previously experienced negative sexual function effects while using hormonal contraceptives. The thematic analysis method was used.Results 'After experience comes insight', 'Lubrication and desire go hand in hand', 'Mental wellbeing comes before desire' and 'The contraceptive counsellor potentially facilitates insight and decision-making' were the main themes found in the study.Conclusions This selected group of women described lubrication difficulties and decreased sexual desire associated with both contraceptive use and the menstrual cycle. Contraceptive use became easier with age and with better understanding. The contraceptive counsellor could facilitate the process. Further choice between hormonal or non-hormonal contraceptive methods depended primarily on experienced adverse effects on mood, and secondarily on sexual function, weighed against the advantages or disadvantages experienced during the person's own menstrual cycle.Following exposure to toxic chemicals, skin uptake is a potential route of intoxication. Therefore, efficient methods for rapid skin decontamination to mitigate systemic effects is of utmost importance. In operational guidelines, skin decontamination is recommended to be performed by dry absorption and washing with water or soapy water. In the present study, evaluation of decontamination efficacy using water or soapy water was performed for five chemicals, three toxic industrial chemicals and two simulants for chemical warfare agents. Decontamination was initiated at time points 5, 15, 45 and 120 minutes after exposure in order to evaluate the time window for efficient decontamination. Experiments were conducted utilizing an in vitro skin penetration model to allow exposure of toxic chemicals on human skin. For all test substances, it was clearly demonstrated that decontamination had greater efficacy when initiated at the earliest time-point while decontamination after 120 minutes was less efficient. Adding soap to the water showed no significant improvement for any of the tested substances. These results are of relevance for the development of efficient operational decontamination procedures.Lipopeptides have been reported to exhibit anti-obesity effects. In this study, we obtained a Bacillus velezensis strain FJAT-52631 that could coproduce iturins, fengycins, and surfactins. Results showed that the FJAT-52631 crude lipopeptide, purified fengycin, iturin, and surfactin standards exhibited strong inhibition activities against lipase with dose-dependence manners (half maximal inhibitory concentration (IC50) = 0.011, 0.005, 0.056, and 0.005 mg/mL, respectively). Moreover, fengycin and surfactin had the comparable activities with orlistat, but iturin not. It was revealed that the inhibition mechanism and type of the lipopeptides were reversible and competitive. The quenching mechanism of lipase was static and only one binding site between lipase and lipopoeptide was inferred from the fluorescence analysis. The docking analysis displayed that fengycin and surfactin could directly interact with the active amino acid residues (Ser or Asp) of lipase, but not with iturin. Our work suggests that the B. velezensis lipopeptides would have great potential to act as lipase inhibitors.Oxidative stress is one of the main causes of significant severe diseases. this website The discovery of new potent antioxidants with high efficiency and low toxicity is a great demand in the field of medicinal chemistry. Herein, we report the design, synthesis molecular modelling and biological evaluation of novel hybrids containing pyrazole, naphthalene and pyrazoline/isoxazoline moiety. Chalcones 2a-e were synthesized efficiently and were used as starting materials for synthesis of a variety of heterocycles. A novel series of pyrazoline 3a-e, phenylpyrazoline 4a-e, isoxazoline 5a-e and pyrazoline carbothioamide derivatives 6a-e were synthesized and screened for in vitro antioxidant activity using 2,2-diphenyl-1-picrylhydrazyl (DPPH), nitric oxide (NO) and superoxide radical scavenging assay as well as 15-lipoxygenase (15-LOX) inhibition activity. Compounds 3a, 4e, 5b, 5c, 6a, 6c, and 6e showed excellent radical scavenging activity in all three methods in comparison with ascorbic acid and 15-LOX inhibition potency using quercetin as standard then were subjected to in vivo study. Catalase (CAT) activity, glutathione (GSH) and malondialdehyde (MDA) levels were assayed in liver of treated rats. Compounds 5b, 5c, and 6e showed significant in vivo antioxidant potentials compared to control group at dose of 100 mg/kg B.W. Molecular docking of compound 6a endorsed its proper binding at the active site pocket of the human 15-LOX which explains its potent antioxidant activity in comparison with standard ascorbic acid.Virus targeted therapy for tumors can effectively prolong the survival rate of patients and has become a new trend for cancer biotherapy. Oncolytic adenovirus (OAd) can specifically replicate in tumor cells, allowing the therapeutic genes carried to be rapidly copied. As known, solid tumors are always hypoxic, and researchers often overlook a key point, the replication of oncolytic adenovirus depends not only on its own activity but also on the cellular hypoxic environment in which the virus replicates. Here we constructed an oncolytic adenovirus carrying Decorin, HRE-Ki67-Decorin, combining the Ki67 promoter up-streamed with hypoxia response element (HRE) sequences to drive adenoviral E1A. The oncolytic adenovirus HRE-Ki67-Decorin had better replication ability under hypoxic conditions, down-regulated cellular immunosuppressed growth factor TGF-β. In addition, HRE-Ki67-Decorin was potent in suppressing tumor growth and participated in the assembly of tumor extracellular matrix (ECM) by expressing Decorin in subcutaneous renal cancer cells tumor models. Tumor sections from HRE-Ki67-Decorin-treated tissues had less collagen fibers and more spread of virus among tumor tissues. These results indicated that chimeric HRE-Ki67 promoter-regulated OAd carrying Decorin might be an effective anti-cancer treatment strategy.
