The unknown characters are first pre-classified into one of three character groups, based on the(More)

MicroRNAs (miRNAs) have been shown to be reliable early biomarkers in a variety of cancers including that of lung. We ascertained whether the biomarker potential of miRNAs could be validated in microscopically normal and easily accessible buccal epithelial brushings from cigarette smokers as a consequence of lung cancer linked 'field carcinogenesis'. We(More)

BACKGROUND AND OBJECTIVES Gastroesophageal reflux disease (GERD) is commonly associated with morbid obesity (MO). Antireflux surgery has a higher failure rate in MO and addresses only one of the comorbidities present.
