Sarcopenia and mortality in different clinical conditions: A meta-analysis.

Objectives: Sarcopenia is recognized to be a health problem which is as serious as obesity, but its relevance to mortality is unclear. We conducted a meta-analysis of cohort studies on lean mass and mortality in populations with different health conditions.

Methods: In this study, a systematic search of PubMed, Cochrane Library and Embase was performed for cohort studies published before Dec 20, 2017 which examined the relationship between lean mass and mortality.

HyBloc: Localization in Sensor Networks with Adverse Anchor Placement.

To determine the geographical positions of sensors, numerous localization algorithms have been proposed in recent years. The positions of sensors are inferred from the connectivity between sensors and a set of nodes called anchors which know their precise locations. We investigate the effect of adverse placement and density of anchors on the accuracies of different algorithms.

Resistin gene polymorphisms and progression of glycaemia in southern Chinese: a 5-year prospective study.

Objective: Human resistin gene (RETN) polymorphisms have been found to be associated with type 2 diabetes (T2DM), insulin resistance and/or obesity. We evaluated, in a 5-year prospective study, whether RETN polymorphisms could predict the progression of glycaemia in southern Chinese.

Design And Patients: We conducted a systematic search for variants in RETN in 70 southern Chinese subjects.
