Two-dimensional transition metal dichalcogenides (TMDs) have drawn strong attention due to their unique properties and diverse applications. However, TMD performance depends strongly on material quality and defect morphology. Experiments show that samples grown by chemical vapor deposition (CVD) outperform those obtained by physical vapor deposition (PVD). Experiments also show that CVD samples exhibit vacancy defects, while antisite defects are frequently observed in PVD samples. Our time-domain ab initio study demonstrates that both antisites and vacancies accelerate trapping and nonradiative recombination of charge carriers, but antisites are much more detrimental than vacancies...

Type 2 diabetes mellitus (T2DM) imparts an increased risk for cognitive decline, specifically executive function, which is important to maintain for diabetes self-management. There is evidence to suggest that exercise improves cognition in healthy older adults; however, the literature in adults with T2DM is lacking. This commentary is in complement to Podolski et al.'s systematic review evaluating the effects of physical activity on cognitive function in adults with T2DM. We have included eight additional studies and further highlight their conclusions on the heterogeneity of the literature thus far...

The new cardiopulmonary resuscitation (CPR) guideline emphasize the importance of chest compression, which was considered as the first step to CPR. The duration for CPR is usually limited to 30 minutes. With the development of new technology and evidence-based medicine, the success of extra longtime CPR has become possible, which is of great significance to some patients with cardiac arrest (CA), but the time limit has not been determined. On February 23rd in 2016, a 76-year-old female patient with respiratory and cardiac arrest who was on the third day after transurethral resection of bladder tumor (TUR-BT) was admitted to the intensive care unit of the General Hospital of Fushun Mining Bureau...

Follistatin (FS) is an important regulatory protein, a natural antagonist for transforming growth factor beta family members activin and myostatin. The diverse biological roles of the activin and myostatin signaling pathways make FS a promising therapeutic target for treating human diseases exhibiting inflammation, fibrosis and muscle disorders, such as Duchenne muscular dystrophy. However, rapid heparin-mediated hepatic clearance of FS limits its therapeutic potential. We targeted the heparin binding loop of FS for site-directed mutagenesis to improve clearance parameters...

An estimated 15.7 million Germans are currently practicing yoga or are at least interested in starting to practice, and they often perceive yoga as a therapeutic approach. From a healthcare system perspective, the situation is less clear. Here, yoga is only recognized as a recreational or preventive activity. When yoga teachers fulfill specific qualifications, their preventive yoga classes are covered by the statutory health insurances. Only those with additional qualifications in medicine or psychotherapy, however, can independently use and promote "yoga therapy...

BACKGROUND: Cardiovascular diseases are a leading cause of premature death worldwide. International guidelines recommend routine delivery of all phases of cardiac rehabilitation. Uptake of traditional cardiac rehabilitation remains suboptimal, as attendance at formal hospital-based cardiac rehabilitation programs is low, with community-based cardiac rehabilitation rates and individual long-term exercise maintenance even lower. Home-based cardiac rehabilitation programs have been shown to be equally effective in clinical and health-related quality of life outcomes and yet are not readily available...
