Evidence suggests that ejaculation frequency may be inversely related to the risk of prostate cancer (PCa), a disease for which few modifiable risk factors have been identified. ObjectiveTo incorporate an additional 10 yr of follow-up into an original analysis and to comprehensively evaluate the association between ejaculation frequency and PCa, accounting for screening, clinically relevant… Continue reading #Ejaculation Frequency and Risk of #Prostate Cancer: Updated Results with an Additional Decade of Follow-up
Reinforcement learning links spontaneous cortical #dopamine impulses to reward
Extrasynaptic levels of dopamine in mouse cortex exhibit spontaneous impulses•Impulses are broadly distributed in amplitude and time, with a rate of about 0.01/s•Feedback was used to train mice to volitionally control their spontaneous impulses•Mice learned to reliably modulate dopamine impulses in order to receive a reward SummaryIn their pioneering study on dopamine release, Romo and… Continue reading Reinforcement learning links spontaneous cortical #dopamine impulses to reward
Long-term Dietary #Flavonoid Intake and Subjective #Cognitive Decline in US Men and Women
To prospectively examine the associations between long-term dietary flavonoids and subjective cognitive decline (SCD). Methods: We followed 49,493 women from the Nurses’ Health Study (NHS) (1984-2006) and 27,842 men from the Health Professionals Follow-up Study (HPFS) (1986-2002). Poisson regression was used to evaluate the associations between dietary flavonoids (flavonols, flavones, flavanones, flavan-3-ols, anthocyanins, polymeric flavonoids,… Continue reading Long-term Dietary #Flavonoid Intake and Subjective #Cognitive Decline in US Men and Women
Distribution of dietary #protein intake in daily meals influences skeletal #muscle hypertrophy via the muscle clock
Distribution of dietary protein across meals influences muscle hypertrophy•BCAAs are involved in hypertrophic effects of protein feeding distribution•Hypertrophic effects of protein feeding distribution require the muscle clock•Breakfast protein intake is correlated with skeletal muscle functions in older women SummaryThe meal distribution of proteins throughout the day is usually skewed. However, its physiological implications and the… Continue reading Distribution of dietary #protein intake in daily meals influences skeletal #muscle hypertrophy via the muscle clock
Associations of #overweight and #obesity with drug-resistant #epilepsy
The group with epilepsy included in this study had a lower proportion of individuals with overweight and obesity than the general population (23.1% versus 42%) in 2015. However, the proportion of patients with obesity in the groups with DRE was significantly higher than that in the general population (17.9% versus 7.1%).•The J-shaped relationship between BMI… Continue reading Associations of #overweight and #obesity with drug-resistant #epilepsy
lab alert: Changes to CDC RT-PCR for SARS-CoV-2 Testing
Audience: Individuals Performing COVID-19 Testing Level: Laboratory Alert After December 31, 2021, CDC will withdraw the request to the U.S. Food and Drug Administration (FDA) for Emergency Use Authorization (EUA) of the CDC 2019-Novel Coronavirus (2019-nCoV) Real-Time RT-PCR Diagnostic Panel, the assay first introduced in February 2020 for detection of SARS-CoV-2 only. CDC is providing… Continue reading lab alert: Changes to CDC RT-PCR for SARS-CoV-2 Testing
#Masitinib is a broad coronavirus 3CL inhibitor that blocks replication of #SARS-CoV-2
There is an urgent need for antiviral agents that treat SARS-CoV-2 infection. We screened a library of 1,900 clinically safe drugs against OC43, a human beta-coronavirus that causes the common cold and evaluated the top hits against SARS-CoV-2. Twenty drugs significantly inhibited replication of both viruses in vitro. Eight of these drugs inhibited the activity… Continue reading #Masitinib is a broad coronavirus 3CL inhibitor that blocks replication of #SARS-CoV-2
Influence of Free #Fatty Acid Concentrations and #Weight Loss on Adipose Tissue Direct Free Fatty Acid Storage Rates
The factors that determine the recycling of free fatty acids (FFA) back into different adipose tissue depots via the direct storage pathway are not completely understood. ObjectiveTo assess the interactions between adipocyte factors and plasma FFA concentrations that determine regional FFA storage rates. DesignWe measured direct adipose tissue FFA storage rates before and after weight… Continue reading Influence of Free #Fatty Acid Concentrations and #Weight Loss on Adipose Tissue Direct Free Fatty Acid Storage Rates
The Relationship Between Prognostic #Nutritional Index and All-Cause #Mortality in Critically Ill Patients: A Retrospective Study
The effectiveness and prognostic value of the prognostic nutritional index (PNI) in critically ill patients are unknown. Hence, this study aimed to analyze the relationship between the PNI and all-cause mortality in critically ill patients. Patients and Methods: Patient data were obtained from the Multiparameter Intelligent Monitoring in Intensive Care III database. The relationship between… Continue reading The Relationship Between Prognostic #Nutritional Index and All-Cause #Mortality in Critically Ill Patients: A Retrospective Study
