BACKGROUND: Activation of dipeptidyl peptidase 4 (DPP4) has been reported to be associated with impairment of insulin signaling in skeletal muscle mass, presumably leading to loss of muscle function. This study was aimed to investigate whether the use of DPP4 inhibitors (DPP4i) could attenuate the progressive loss of muscle mass in patients with type 2 diabetes. METHODS: A total 105 patients with type 2 diabetes (mean age 62 ± 12 years; 39% female) were studied in this retrospective observational study...

Albeit extensively utilized, herb extraction process (HEP) is hard to be monitored because of its batch nature and the fluctuating quality of raw materials. Process analytical tools like near infrared spectroscopy (NIRS) can offer nondestructive examinations and collect abundant data of the process, which in principle contain the information about the quality of both the product and the process itself. However, extra effort is often required for the data mining of such process measurements, and extracting knowledge of the quality of process can be even harder...

Diesel engines serve many purposes in modern oil and gas extraction activities. Diesel particulate matter (DPM) emitted from diesel engines is a complex aerosol that may cause adverse health effects depending on exposure dose and duration. This study reports on personal breathing zone (PBZ) and area measurements for DPM (expressed as elemental carbon) during oil and gas extraction operations including drilling, completions (which includes hydraulic fracturing) and servicing work. Researchers at the National Institute for Occupational Safety and Health (NIOSH) collected 104 full-shift air samples (49 PBZ and 55 area) in Colorado, North Dakota, Texas, and New Mexico during a four year period from 2008-2012 The arithmetic mean (AM) of the full shift TWA PBZ samples was 10 µg/m(3); measurements ranged from 0...

Repeated apneas are associated with severe hypoxemia that may ultimately lead to loss of consciousness in some breath-hold divers. Despite increasing number of practitioners, the relationship between apnea-induced hypoxia and neurocognitive functions is still poorly understood in the sport of free diving. To shed light onto this phenomenon, we examined the impact of long-term breath-hold diving training on attentional processing, short-term memory, and long-term mnesic and executive functions. Thirty-six men matched for age, height and weight were separated into three groups [12 elite breath-hold divers (EBHD, mean static apnea best time 371 sec, 105 months mean apnea experience); 12 novice breath-hold divers (NBHD, mean best time 243 sec, 8...

Alternative strategies are required to enhance the diagnosis of silent hepatitis C virus (HCV) infections in hard-to-reach key populations at risk. Among them, HCV prevalence and bio-behavioural data is scarce for HIV-negative men who have sex with men (MSM) and men and trans-women sex workers. We sought to describe and assess the potential benefits of a community-based one-step HCV screening and confirmatory strategy for these populations in Barcelona. The screening strategy based on a real-time RT-PCR assay for HCV-RNA detection in dried-blood spots (DBS) was validated and implemented in addition to an antibody point-of-care test in a community centre...
