Lack of association between Glu298Asp polymorphism and coronary artery disease in North Indians.

Nitric Oxide (NO) is an important molecule carrying number of different functions in humans. Published studies suggest that it may inhibit several key steps involved in the pathogenesis of atherosclerosis. Inhibition or reduction of NO due to Glu298Asp polymorphism may accelerate atherosclerosis.

Stigma, help-seeking attitudes, and use of psychotherapy in veterans with diagnoses of posttraumatic stress disorder.

Survey and medical record data from 482 Veterans Affairs (VA) patients who recently received diagnoses of posttraumatic stress disorder (PTSD) were examined to determine need and predisposing factors associated with utilization of psychotherapy and counseling. More than half (58%) of participants initiated VA psychotherapy for PTSD within a year of diagnosis. Of those, one third completed eight or more sessions.

Discovery of potent, selective, and orally active carboxylic acid based inhibitors of matrix metalloproteinase-13.

The matrix metalloproteinase enzyme MMP-13 plays a key role in the degradation of type II collagen in cartilage and bone in osteoarthritis (OA). An effective MMP-13 inhibitor would therefore be a novel disease modifying therapy for the treatment of arthritis. Our efforts have resulted in the discovery of a series of carboxylic acid inhibitors of MMP-13 that do not significantly inhibit the related MMP-1 (collagenase-1) or tumor necrosis factor-alpha (TNF-alpha) converting enzyme (TACE).

Identification of dipeptidyl nitriles as potent and selective inhibitors of cathepsin B through structure-based drug design.

Cathepsin B is a member of the papain superfamily of cysteine proteases and has been implicated in the pathology of numerous diseases, including arthritis and cancer. As part of an effort to identify potent, reversible inhibitors of this protease, we examined a series of dipeptidyl nitriles, starting with the previously reported Cbz-Phe-NH-CH(2)CN (19, IC(50) = 62 microM). High-resolution X-ray crystallographic data and molecular modeling were used to optimize the P(1), P(2), and P(3) substituents of this template.

Potent and selective non-peptidic inhibitors of endothelin-converting enzyme-1 with sustained duration of action.

Potent and selective non-peptidic inhibitors of human endothelin-converting enzyme-1 (ECE-1) have been designed as potential modulators of endothelin (ET-1) production in vivo. Because of its unique structural characteristics and long duration of action in vivo, the dual ECE-1 and neutral endopeptidase 24.11 (NEP) inhibitor, CGS 26303, was selected as an attractive lead for further optimization of potency and selectivity.

Carboxy-substituted cinnamides: a novel series of potent, orally active LTB4 receptor antagonists.

A series of carboxy-substituted cinnamides were investigated as antagonists of the human cell surface leukotriene B4 (LTB4) receptor. Binding was determined through measurement of [3H]LTB4 displacement from human neutrophils. Receptor antagonism was confirmed through a functional assay, which measures inhibition of Ca2+ release in human neutrophils.

Patients' experiences of chemotherapy: side-effects of carboplatin in the treatment of carcinoma of the ovary.

There has been little investigation of the side-effects experienced by women receiving adjuvant carboplatin in the treatment of ovarian cancer. This study aimed to describe the range of problems experienced by patients and to estimate incidence and severity of side-effects over the treatment period. Eleven patients participated and completed a 75-item self-report questionnaire at each course of treatment.

Patient satisfaction on a medical day ward: a comparison of nurse-led and physician-led services.

Patient satisfaction on a medical Day Ward at Worthing Hospital, England, was investigated using a self-report questionnaire. One-hundred and fifty-five respondents provided quantitative data on waiting times, patient information, anxiety, ward environment, and nursing care. Patients attending for physician-led, investigative procedures were found to be more anxious and generally far less satisfied than those attending for nurse-led, non-investigative procedures.
