BACKGROUND One of the primary dose-limiting toxicities during thoracic irradiation is acute esophagitis (AE). The aim of this study is to investigate dosimetric and clinical predictors for AE grade ≥ 2 in patients treated with accelerated radiotherapy for locally advanced non-small cell lung cancer (NSCLC). PATIENTS AND METHODS 66 NSCLC patients were included in the present analysis: 4 stage ...
The sharp distinction drawn between firms rated narrowly above (BBB–) and below (BB+) the investment-grade cutoff provides variation in debt financing availability unrelated to firm fundamentals. We exploit this market segmentation to identify an asymmetric effect of debt capital supply on voluntary disclosure: BB+ firms step up disclosure in response to high-yield bond mutual fund outflows. Th...
Net pay thickness is defined as that portion of a reservoir which contains economically producible hydrocarbons with today’s technology, prices, and costs. This thickness is a key parameter of the volumetric calculation of in-place hydrocarbons, well test interpretation, and reservoir characterization. A reservoir interval is considered as net pay when it contains hydrocarbons that can flow at ...
BACKGROUND Many men with elevated prostate-specific antigen (PSA) levels in serum do not have aggressive prostate cancer and undergo unnecessary biopsy. Retrospective studies using cryopreserved serum suggest that four kallikrein markers can predict biopsy outcome. METHODS Free, intact and total PSA, and kallikrein-related peptidase 2 were measured in cryopreserved blood from 6129 men with el...

Cooley Law School admitted students based on either of two alternatives: (1) the applicant’s LSAT score alone or (2) the student’s Cooley Admissions Index, which is the sum of the applicant’s undergraduate grade point average multiplied by 15, plus the applicant’s LSAT score. In mathematical terms, the index is expressed by the ...

RESULTS Using published PSA density and PSA mass density cutoff values, men with higher body mass indices and...
