User behavior, influence factors, and impacts on real-world pollutant emissions from the household heating stoves in rural China.

Household heating stoves are commonly used for heating in rural China during winter and are responsible for a large portion of the particulate matter in the atmosphere. Pollutant emissions from household stoves are influenced by user behaviors in actual use, in addition to purely technological reasons (i.e.

A comparison of ARMS and mutation specific IHC for common activating EGFR mutations analysis in small biopsy and cytology specimens of advanced non small cell lung cancer.

We have compared mutation analysis by Amplification Refractory Mutation System (ARMS) and epidermal growth factor receptor (EGFR) mutant-specific antibodies for their ability to detect two common activating EGFR mutations in a cohort of 115 advanced non-small cell lung cancer (NSCLC), including cytology material, core biopsy, and bronchoscopic biopsies. Assessment of EGFR mutation status was performed by using antibodies and ARMS assay specific to the two major forms of mutant EGFR, exon 19 deletion E746-A750 (c.2235_2249del15 or c.

[Associations between Ser447Ter gene polymorphism of lipoprotein lipase and atherosclerotic cerebral infarction].

Objective: To investigate the relationship between lipoprotein lipase (LPL) gene Ser447Ter polymorphism and atherosclerotic cerebral infarction (CI), and to investigate the effect of Ser447Ter polymorphism on plasma lipids, carotid intima-media thickness (IMT) and carotid artery plaque (CAP) in patients with CI.

Methods: PCR-restriction fragment lengh polymorphism (PCR-RFLP) technique was used to detect LPL gene Ser447Ter polymorphism in 166 patients with CI (CI group) and 72 healthy subjects (control group). Carotid IMT and CAP were measured with carotid color ultrasonographic doppler for the patients and the controls.
