The sensitivity was higher for identifying radicular cysts than for other lesions.

Using deep learning object detection technology, maxillary cyst-like lesions could be detected in approximately 75-77%.

Ventricular tachycardia (VT) is a frequent cause of mortality and morbidity in patients with ischemic heart disease (IHD). We aim to perform a systematic review and meta-analysis of randomized controlled trials (RCT) of radiofrequency catheter ablation (RCA) of VT in patients with IHD and to discuss its appropriate timing and limitations.

Literature searches of MEDLINE, CENTRAL, the Cochrane Database of Systematic Reviews, Health Technology Assessment, and PsycINFO were performed in February 2020. RCTs comparing RCA vs conventional management for VT in patients with IHD and previous or planned implantable cardioverter defibrillator (ICD) were identified. Clinical outcomes included all-cause mortality, cardiovascular mortality, cardiovascular hospitalization, VT storm, recurrent VT/ventricular fibrillation (VF), appropriate ICD therapies, and appropriate ICD shocks. Using a random-effects model, relative risk (RR) and 95% confidence intervals (CI) were calculated for each outcome.

A total of 6 RCTs (N= 791) met inclusion criteria. RCA was associated with significantly lower VT storm (RR 0.70; CI
0.51 to 0.94, p= 0.02) and appropriate ICD therapies (RR 0.69; CI
0.54 to 0.88, p= 0.003), including appropriate ICD shocks (RR 0.66; CI
0.47 to 0.92, p= 0.02). There was no significant difference in all-cause or cardiovascular mortality, cardiovascular hospitalization, and recurrent VT/VF.

Radiofrequency catheter ablation for VT in patients with IHD was associated with a reduced risk of VT storm, ICD therapies, and ICD shocks. There is a need for future carefully designed RCTs that incorporate improved RCA procedural aspects.

Sleep is essential for overall health and can impact academic performance. Prior research reports reduced sleep time in college students. Poor sleep may impact physical activity (PA) and sedentary behavior, or vice versa, but has not been examined extensively in this population. Therefore, the purpose of thisstudy was to examine markers of sleep quality, PA, and sedentary behavior in college students using objective means.

A convenience sample of college students underwent body composition analysis and 7-day objective PA and sleep assessment via accelerometry.

Among 81 college students (53 women), there was no association between total sleep time (TST) and weekly average PA. TST was negatively associated with sedentary minutes per day, sedentary bouts per day, and total time in sedentary bouts per day. Greater sedentary bouts per day and average sedentary minutes per day were seen in those with a TST < 6h, with no difference in body composition. Further, TST was negatively associated with sedentary minutes accumulated on the subsequent day, for all 7days.

In a primarily residential college student cohort, poor sleep is associated with sedentary behavior more than PA. These students, who require a high amount of transport PA to and from campus during the week, are compensating by sleeping more and moving less on the weekend.

A generally-accepted dogma is that neurons have the highest energy demands of all brain cells, and calculated neuronal rates of glucose oxidation in awake, resting brain accounts for 70-80%, with astrocytes 20-30%. However, these proportions do not take cell type volume fractions into account. Selleckchem S3I-201 To evaluate the conclusion that neuron-astrocyte glucose oxidation rates are similar when adjusted for astrocytic volume fraction (Hertz, Magn Reson Imaging 2011; 29, 1319), the present study analyzed data from 31 studies. On average, astrocytes occupy 6.1, 9.6, and 15% of tissue volume in hippocampus, cerebral cortex, and cerebellum, respectively, and regional astrocytic metabolic rates are adjusted for volume fraction by multiplying by 17.6, 11.4, and 6.8, respectively. After adjustment, astrocytic glucose oxidation rates in resting awake rat brain are 4-10 fold higher than neuronal oxidation rates. Volume-fraction adjustment also increases brain glycogen concentrations and utilization rates to be similar to or exceed exercising muscle. Ion flux calculations to evaluate sodium/potassium homeostasis during neurotransmission are not correct if astrocyte-neuron volume fractions are assumed to be equal. High rates of glucose and glycogen utilization after adjustment for volume fraction indicate that astrocytic energy demands are much greater than recognized, with most of the ATP being used for functions other than glutamate processing in the glutamate-glutamine cycle, challenging the notion that astrocytes 'feed hungry neurons'.Barley is one of the most important crops in the world. Barley is used as both food and feed and is important for malt production. Demands for malting quality differ among countries and customs. Malting quality is a complex characteristic involving barley genetics, the environmental conditions during barley growth, and the technological parameters of the malting process. In this study, the hypothesis was that there were no differences between two groups of barley varieties with different but defined malting qualities, which was tested using RNA sequencing during selected stages of malting. In total, 919 differentially transcribed genes between the two barley groups were identified and annotated. Differentially expressed genes (DEGs) were primarily assigned to gene ontology (GO) terms of oxidation-reduction process - oxidoreductase activity, response to stress, carbohydrate metabolic process, and proteolysis - hydrolase activity, and metal ion binding. Genes connected with the plasma membrane and its integral components also play important roles in malting quality.
