Biogenic material nanoparticles together with bacterias and their apps within water treatment: a review.
Aim FLZ, a novel promising dopamine neuroprotective agent, is designed to treat Parkinson's disease. F7G and F21G are FLZ major active Phase II metabolites whose exposure are nearly 100-times higher than FLZ, may chiefly produce effectiveness in human. Measurement of F7G and F21G in plasma samples is critical for investigating its pharmacokinetics in clinical studies. Methodology & results Plasma samples were extracted by SPE method and then analyzed by a newly established ultra-UHPLC-MS/MS method. Conclusion For the first time, a reliable and robust bioanalytical method for F7G and F21G detection was successfully applied in a first-in-human study.Objective The aim of this study is to examine the effects of cognitive and physical loads on dynamic and static balance performance of healthy older adults under single-, dual-, and multi-task conditions. Background Previous studies on postural control in older adults have generally used dual-task methodology, whereas less attention has been paid to multi-task performance, despite its importance in many daily and occupational activities. Method The effects of single versus combined (dual-task and multi-task) cognitive (to speak out the name of the weekdays in a reverse order) and physical (with three levels including handling weights of 1, 2, and 3 kg in each hand) loads on dynamic and static balance performance of 42 older adults (21 males and 21 females) aged ≥60 years were examined. Dynamic and static balance measures were evaluated using the Timed Up and Go (TUG) and stabilometer (sway index) tests, respectively. Results The TUG speed of female participants was generally slower than that of male participants. Selleck DS-8201a Age had no effect on balance performance measures. Under dual-task conditions, cognitive load decreased the dynamic balance performance, while the physical task levels had no effect. The dual-task conditions had no impact on the static balance performance. The effects of cognitive and physical loads on dynamic balance performance varied under dual- and multi-task conditions. Conclusion The findings highlight differences between dual- and multi-task protocols and add to the understanding of balance performance in older adults under cognitive and physical loads. Application The present study highlights differences between dual- and multi-task methodologies that need to be considered in future studies of balance and control in older adults.Purpose In the midst of a global pandemic, evidence suggests that similar to other severe respiratory viral infections, patients with cancer are at higher risk of becoming infected by COVID-19 and have a poorer prognosis. Methods We have modeled the mortality and the intensive care unit (ICU) requirement for the care of patients with cancer infected with COVID-19 in Latin America. A dynamic multistate Markov model was constructed. Transition probabilities were estimated on the basis of published reports for cumulative probability of complications. Basic reproductive number (R0) values were modeled with R using the EpiEstim package. Estimations of days of ICU requirement and absolute mortality were calculated by imputing number of cumulative cases in the Markov model. Results Estimated median time of ICU requirement was 12.7 days, median time to mortality was 16.3 days after infection, and median time to severe event was 8.1 days. Peak ICU occupancy for patients with cancer was calculated at 16 days after infection. Deterministic sensitivity analysis revealed an interval for mortality between 18.5% and 30.4%. With the actual incidence tendency, Latin America would be expected to lose approximately 111,725 patients with cancer to SARS-CoV-2 (range, 87,116-143,154 patients) by the 60th day since the start of the outbreak. Losses calculated vary between less then 1% to 17.6% of all patients with cancer in the region. Conclusion Cancer-related cases and deaths attributable to SARS-CoV-2 will put a great strain on health care systems in Latin America. Early implementation of interventions on the basis of data given by disease modeling could mitigate both infections and deaths among patients with cancer.Background Cannabis is the most commonly used illicit drug on college campuses. Research suggests that Student Service Members/Veterans (SSM/V) may be more likely to use alcohol than civilian students, but little research has focused on cannabis use in these two samples. Objectives The purpose of the current study was to compare cannabis use frequency, cannabis use disorder (CUD) symptoms, and cannabis-related problems between civilian students and SSM/V. A second aim was to determine if group differences in these outcomes were moderated by symptoms of depression, stress, or anxiety. Methods The sample included 164 college SSM/V (80.4% female, 19.6% male) and 456 civilian (78% female, 22% male) college students. Participants completed an online survey assessing demographics, number of days of past month cannabis use, cannabis-related problems, CUD symptoms, and a measure of anxiety, depression, and stress. Results Negative binomial regressions indicated no significant differences in number of days of past-month cannabis use or past-year cannabis-related problems between civilian students and SSM/V, although SSM/V reported more past-year CUD symptoms. Moderation analyses revealed that at elevated levels of anxiety, SSM/V students used cannabis more frequently than civilian students. Conclusion These findings indicate that when experiencing elevated levels of anxiety, SSM/V use cannabis more frequently than civilian students, suggesting that anxiety may be a more prominent risk factor for frequency of cannabis use for SSM/V compared to civilian students. Education, prevention, and intervention efforts specifically addressing anxiety in this demographic are needed.Background - Long QT syndrome (LQTS) is characterized by a prolonged heart rate corrected QT interval (QTc). Genome-wide association studies identified common genetic variants that collectively explain ~8-10% of QTc variation in the general population. Methods - Overall, 423 patients with type 1-3 LQTS were genotyped for 61 QTc-associated genetic variants used in a prototype QTc-polygenic risk score (QTc-PRS). A weighted QTc-PRS (range = 0-154.8 ms) was calculated for each patient and the Framingham Heart Study (FHS) population-based reference cohort (n=853). Results - The average QTc-PRS in LQTS was 88.0 ± 7.2 and explained only ~2.0% of the QTc variability. The QTc-PRS in LQTS probands (n=137; 89.3 ± 6.8) was significantly greater than both FHS controls (87.2 ± 7.4, difference-in-means (DIM) ± standard error 2.1 ± 0.7, P less then 0.002) and LQTS genotype-positive family members (87.5 ± 7.4, DIM 1.8 ± .7, P less then 0.009). There was no difference in QTc-PRS between symptomatic (n=156, 88.6 ± 7.3) and asymptomatic patients (n=267; 87.
