BACKGROUND There are few reports on total body skeletal muscle mass (SM) in Chinese. The objective of this study is to establish a prediction model of SM for Chinese adults. METHODOLOGY Appendicular lean soft tissue (ALST) was measured by dual energy X-ray absorptiometry (DXA) and SM by magnetic resonance image (MRI) in 66 Chinese adults (52 men and 14 women). Images of MRI were segmented int...

Lean body mass (LBM) and muscle mass remain difficult to quantify in large epidemiological studies due to the unavailability of inexpensive methods. We therefore developed anthropometric prediction equations to estimate the LBM and appendicular lean soft tissue (ALST) using dual-energy X-ray absorptiometry (DXA) as a reference method. Healthy volunteers (n = 2,220; 36% women; age 18-79 yr), rep...

OBJECTIVES Sarcopenia and visceral obesity have been suggested to aggravate each other, resulting in a vicious cycle. However, evidence based on prospective study is very limited. Our purpose was to investigate whether visceral fat promotes a decrease in skeletal muscle mass and vice versa. METHODS We observed changes in anthropometric and body composition data during a follow-up period of 27...

CD45, a receptor-like protein tyrosine phosphatase (PTP), plays an essential role in lymphocyte development and immune responses. Recent evidence suggests that dimerization of CD45 downregulates its function. However, the mechanisms by which CD45 dimerization is regulated remain unclear, and there is no direct evidence that the PTP activity of CD45 dimers is less than that of monomers. CD45 in ...

Skeletal muscle (SM) is a large and physiologically important compartment. Adipose tissue is found interspersed between and within SM groups and is referred to as intermuscular adipose tissue (IMAT). The study objective was to develop prediction models linking appendicular lean soft tissue (ALST) estimates by dual-energy X-ray absorptiometry (DXA) with whole body IMAT-free SM quantified by magn...

This study investigates the effectiveness of asynchronous online quizzes in improving student learning outcomes higher education. Specifically, we compare impact two teaching methods - Synchronous Lecture and Asynchronous Tutorial pair (SLAT) versus (ALST) delivering weekly to 70 undergraduate computer science students. Our results show that SLAT outperformed ALST method enhancing students' aca...

This paper presents an overview of the ALST project, in which speech technologies (speech recognition and speech synthesis) and machine translation were implemented in the voice-over of non-fictional genres and in the audio description of films. The paper presents the project rationale, a brief description of the experiments carried out within the project, as well as its main findings.

Tea, ex tracts, solutions, and other preparations from plants with a putative antihypergly cemic effect have a worldwide utilization in the treatment of diabetes (1). Among them, the tea prepared from leaves of jambolan [Syzygium jambos (L.) Alst or Syzyguium cumini (L.) Skeels] is largely used in our city (2) and elsewhere (3). We demonstrated that the tea and extracts from different parts of ...
