BACKGROUND: Low level of cardiorespiratory fitness has been recognized as an important independent and modifiable risk factor of increased morbidity and mortality. However, in standard outpatient settings, patients are not routinely screened for fitness and advantages of such testing for the management of type 2 diabetes have not been defined. Aim To describe the toleration of a fast, simple and practicable fitness test (2-min step-in-place test) by overweight/obese type 2 diabetics and their performance indicated by 2-min step-in-place test score (STS)...

Combining endurance training with resistance training (RT) may attenuate skeletal muscle hypertrophic adaptation versus RT alone; however, the underlying mechanisms are unclear. We investigated changes in markers of ribosome biogenesis, a process linked with skeletal muscle hypertrophy, following concurrent training versus RT alone. Twenty-three males underwent eight weeks of RT, either performed alone (RT group, n = 8), or combined with either high-intensity interval training (HIT+RT group, n = 8), or moderate-intensity continuous training (MICT+RT group, n = 7)...

Recently, an pressing requirement of solid-state lighting sources with high-performance and low-cost has motivated increasing research in metal halide perovskites. But the relatively low emission efficiency and poor operation stability of perovskite light-emitting diodes (LEDs) are still critical drawbacks. In this study, a strategy of solution-processed all-inorganic-heterostructure was proposed to overcome the emission efficiency and operation stability issues facing perovskite LEDs' challenges. Solution-processed n-ZnO nanoparticles and p-NiO are used as the carrier-injectors to fabricate all-inorganic-heterostructured CsPbBr3 quantum dot LEDs, and a high-efficiency green emission is achieved with maximum luminance of 6093...

M Newman, R Newman, T Hughes, K Vadher, K L Barker
Timed loaded standing (TLS) is a suggested measure of back muscle endurance for people with vertebral osteoporosis. Surface electromyography revealed back muscles work harder and fatigue during TLS. The test end-point and total time were associated with back fatigue. The findings help demonstrate the concurrent validity of the TLS test. INTRODUCTION: The TLS test is suggested as a measure of back muscle endurance for patients with vertebral osteoporosis. However, to date, no study has demonstrated that TLS does measure back extensor or erector spinae (ES) muscle endurance...

Conventional synthetic hydrogels are intrinsically soft and brittle, which seriously limit the scope of their applications. A variety of approaches have been reported to improve the mechanical strength of hydrogels. However, a facile and ubiquitous strategy to prepare hydrogels with high mechanical strength and stiffness is still a challenge. Here we report a general strategy to prepare highly filled microcomposite hydrogels with high mechanical performance by using ultrasonic assistant. The microparticles were dispersed in the polymer network evenly, which result in the homogeneous and closely packed structures...

Between 1935 and 1985, Irish law criminalized the sale and importation of condoms. Activists established illegal markets to challenge the law and alleviate its social consequences. They distributed condoms through postal services, shops, stalls, clinics, and machines. Though they largely operated in the open, their activities attracted little direct punishment from the state, and they were able to build a stable network of medical and commercial family planning services. We use 30 interviews conducted with former activists to explore this history...
