Upregulation of neutrophil gelatinase-associated lipocalin by ErbB2 through nuclear factor-kappaB activation.

ErbB2 (HER2, neu) is a receptor tyrosine kinase overexpressed in about 25% of invasive breast carcinomas. Neutrophil gelatinase-associated lipocalin (NGAL) is a secreted glycoprotein expressed in a variety of cancers, including breast carcinomas. NGAL can inhibit erythroid cell production, leading to anemia.

Delphi-derived development of a common core for measuring complementary and alternative medicine prevalence.

Assessing complementary and alternative medicine (CAM) use remains difficult due to many problems, not the least of which is defining therapies and modalities that should be considered as CAM. Members of the International Society for Complementary Medicine Research (ISCMR) participated in a Delphi process to identify a core listing of common CAM therapies presently in use in Western countries. Lists of practitioner-based and self-administered CAM were constructed based on previous population-based surveys and ranked by ISCMR researchers by perceived level of importance.

ErbB2-mediated Src and signal transducer and activator of transcription 3 activation leads to transcriptional up-regulation of p21Cip1 and chemoresistance in breast cancer cells.

Overexpression of the ErbB2 receptor tyrosine kinase is prevalent in approximately 30% of human breast cancers and confers Taxol resistance. Our previous work has shown that ErbB2 inhibits Taxol-induced apoptosis in breast cancer cells by transcriptionally up-regulating p21(Cip1). However, the mechanism of ErbB2-mediated p21(Cip1) up-regulation is unclear.

The natural history of chronic obstructive pulmonary disease.

Chronic obstructive pulmonary disease (COPD) is a leading cause of morbidity and mortality in the USA, and it remains one of the few diseases that continues to increase its numbers. The development and progression of COPD can vary dramatically between individuals. A low level of lung function remains the cornerstone of COPD diagnosis and is a key predictor of prognosis.

Carboxyhaemoglobin concentration, smoking habit, and mortality in 25 years in the Renfrew/Paisley prospective cohort study.

Objective: To investigate how carboxyhaemoglobin concentration is related to smoking habit and to assess whether carboxyhaemoglobin concentration is related to mortality.

Design: Prospective cohort study.

Setting: Residents of the towns of Renfrew and Paisley in Scotland.
