Scottish Blackface lamb viability records at birth, and postnatal survival from 1 day to 14 days, from 15 days to 120 days and from 121 days to 180 days were used to determine influential factors and to estimate variance components of lamb survival traits. The binary trait viability at birth was analysed using a linear model whereas the postnatal survival traits were analysed as continuous trai...

OBJECTIVES To explore whether the inhalation of coal mine dust increases the risk of premature death in miners, a survival analysis was conducted in a cohort of 2738 patients with simple pneumoconiosis in the Huai-Bei coal mine, in China. METHODS Age specific mortalities were calculated by disease severity in terms of pneumoconiotic category with the life table method. The progressions from s...

In most preclinical disease models, survival analyses are the gold standard for measuring the efficacy of medical interventions such as therapeutics or vaccines. In these analyses, treatment regimens that promote the survival and/or reduce the morbidity of experimental subjects (e.g., mice) are tested for efficacy. Although these analyses appear to be relatively straightforward, there are assoc...

The aim of this paper is to give empirical evidence of the fundamental mechanisms underlying the resource systemics: time compression diseconomies, asset mass efficiency, and interconnectedness of assets. It assumes that time, resource properties and interactions are the critical elements leading to accumulation of idiosyncratic resources, firm performance and survival. Results from a Cox regre...

Relative 5-year survival for stomach cancer has increased gradually in Osaka for more than two decades, while women show a small but consistently lower survival for it. We analyzed gender differences in stomach cancer survival, using relative survival model proposed by Dickman et al. Study subjects were reported stomach cancer cases diagnosed in 1975-99. We estimated the excess hazard ratios (E...

conclusions herein we have described the stata package “adpredsurv” for calculation of the nam-d’agostino x2 goodness of fit test as well as cut point-free and cut point-based nri, relative and absolute idi, and survival-based regression analyses. we hope this work encourages the use of novel methods in examining predictive capacity of the emerging plethora of novel biomarkers. background a fun...

Objective(s): Apoptotic effect of apoptin has been demonstrated in numerous studies. However, its tumor specificity has been questioned by some reports. The aim of this study was to confine the expression of apoptin in the prostate tumor cells by inducing its gene expression under the control of a chimeric enhancer composing of prostate-specific membrane antigen (PSMA) and prostate-specific ant...

abstract: background and purpose: the survival rate of gastric cancer patients has significantly increased during the last decades because of the advances in this type of cancer treatment. the purpose of the current study was to examine the survival levels of gastric cancer through weibull regression and its affective causes. materials and methods: in this research, the records and personal inf...
