The molecular docking studies predicted the binding modes of the compounds with RT and explained the activity differences for the enantiomers.  https://www.selleckchem.com/products/sn-001.html  Although the rat pharmacokinetic assay indicated a poor oral metabolism of the hydroxyl compound, the promising antiviral activity of the chiral hydroxyl-substituted biphenyl-diarylpyrimidines provided valuable lead compounds for further anti-HIV drug design.Drugs targeting human topoisomerase II (topoII) are used in clinical practice since decades. Nevertheless, there is an urgent need for new and safer topoII inhibitors due to the emergence of secondary malignancies and the appearance of resistance mechanisms upon treatment with topoII-targeted anticancer drugs. In the present investigation, we report the discovery of a new topoII inhibitor, whose design was based on the structure of the natural product trypthantrin, a natural alkaloid containing a basic indoloquinazoline moiety. This new topoII inhibitor, here numbered compound 5, is found to inhibit topoII with an IC50 of 26.6 ± 4.7 μM. Notably, compound 5 is more potent than the template compound trypthantrin, and even than the widely used topoII-targeted clinical drug etoposide. In addition, compound 5 also exhibits high water solubility, and a promising antiproliferative activity on different tumor cell lines such as acute leukemia, colon, and breast cancer. In light of these results, compound 5 represents a promising lead for developing new topoII inhibitors as anti-cancer therapeutic agents.The capsid assembly is a significant phase for the hepatitis B virus (HBV) lifespan and is an essential target for anti-HBV drug discovery and development. Herein, we used scaffold hopping, bioisosterism, and pharmacophore hybrid-based strategies to design and synthesize six series of various heterocycle derivatives (pyrazole, thiazole, pyrazine, pyrimidine, and pyridine) and screened for in vitro anti-HBV non-nucleoside activity. Drug candidate NZ-4 and AT-130 were used as lead compounds. Several compounds exhibited prominent anti-HBV activity compared to lead compound NZ-4 and positive drug Lamivudine, especially compound II-8b, showed the most prominent anti-HBV DNA replication activity (IC50 = 2.2 ± 1.1 μM). Also compounds IV-8e and VII-5b showed the best in vitro anti-HBsAg secretion (IC50 = 3.8 ± 0.7 μM, CC50 > 100 μM) and anti-HBeAg secretion (IC50 = 9.7 ± 2.8 μM, CC50 > 100 μM) respectively. Besides, II-8b can interact HBV capsid protein with good affinity constants (KD = 60.0 μM), which is equivalent to lead compound NZ-4 ((KD = 50.6 μM). The preliminary structure-activity relationships (SARs) of the newly synthesized compounds were summarized, which may help researchers to discover more potent anti-HBV agents.Despite advances in understanding the consequences of age-related episodic memory decline for future simulation, much remains unknown regarding changes in the neural underpinnings of future thinking with age. We used a repetition suppression paradigm to explore age-related changes in the neural correlates of emotional future simulation. Younger and older adults simulated positive, negative, and neutral future events either 2 or 5 times. Reductions in neural activity for events simulated 5 versus 2 times (i.e., repetition suppression) identify brain regions responsive to the specific emotion of simulated events. Critically, older adults showed greater repetition suppression than younger adults in the temporal pole for negative simulations, and the cuneus for positive simulations. These findings suggest that older adults distance themselves from negative future possibilities by thinking about them in a more semantic way, consistent with the view that older adults down-regulate negative affect and up-regulate positive affect. More broadly this study increases our understanding of the impact of aging on the neural underpinnings of episodic future simulation.
  Although the mechanism of post-concussion syndrome remains unclear, psychological factors are thought to be associated with its development. Cognitive behavioral therapy is the gold standard for psychological disorders; however, its effects on post-concussion syndrome remain unclear. Through this meta-analysis, we assessed the effects of cognitive behavioral therapy on post-concussion syndrome following traumatic brain injury.
 
  Six electronic databases were searched from inception to September 15, 2019, for randomized controlled trials evaluating the effects of cognitive behavioral therapy for adults with post-concussion syndrome. Primary outcomes included the severity of symptoms of post-concussion syndrome, depression, anxiety, and social integration. Secondary outcomes were fatigue, cognitive function, and quality of life. Effects were estimated through the calculation of Hedge's g and 95% confidence interval using a random effects model. Sensitivity analyses were conducted by excluding studies in whichry.
  Hysterectomy, one of the most frequent surgical procedures in women, is commonly performed by a minimally-invasive approach (laparoscopic or vaginal) as recommended by the French guidelines. The French authorities aim to have 66 % of all procedures performed as same-day surgery in 2020. The aim of this study was to evaluate the feasibility and identify factors associated with success or failure of same-day surgery for minimally-invasive hysterectomy.
 
  We conducted a prospective double-center observational study at the Caen and Amiens University Hospitals between September 2017 and May 2018 including hospitalized patients managed for a laparoscopic or vaginal hysterectomy. Patients were younger than 70 and have no major medical problems. The patients were placed into a "fit" or "unfit" group according to their Post Anaesthetic Discharge Scoring System (PADSS) score 6 h post-surgery. All the patients were asked to complete an assessment questionnaire during their hospitalization.
 
  Of the 50 included patients, half were placed in the "fit" group. A history of laparotomy was significantly predictive of failure of same-day discharge (p = 0.003) but not uterine size or Body Mass Index (BMI). The main barriers for discharge were pain (p<0.001) and postoperative nausea/vomiting (PONV) (p<0.001). Four patients, all in the "unfit" group, had Clavien-Dindo grade 1 postoperative complications.
 
  Same-day minimally invasive hysterectomy is a feasible and safe procedure. Factors associated with same-day hysterectomy failure were laparotomy, pain and postoperative nausea/vomiting.
