background and objective: it is well known that menstrual period and ovarian function are affected by chemotherapy. although breast cancer is the most common cause of chemotherapy in women and ovarian hormones have very important direct and indirect effects on overall survival, disease-free survival, and life quality of patients, but few studies have addressed the frequency and related factors ...

from 1986 to 1996, 1020 renal transplants were performed at our center. the purposes of this study were. 1) to evaluate the patient and graft survival rates and 2) to see if some donors and recipient characteristics such as age, sex and relationship had any effects on graft survivals. 571 transplants were from living related donors (lrd) and 446 from living unrelated donors (lud). 65.9% of reci...

background: breast cancer arising in young patients (≤ 40 years) is being considered as a distinct clinical entity with more aggressive tumor features and poorer survival. our aim was to assess the impact of age on survival among a large group of iranian women diagnosed with breast cancer. methods: in a cross-sectional study, demographic and clinicopathological characteristics of patients with ...

The generation of mice lacking SCYL1 or SCYL2 and the identification of Scyl1 as the causative gene in the motor neuron disease mouse model muscle deficient (Scyl1(mdf/mdf) ) demonstrated the importance of the SCY1-like family of protein pseudokinases in neuronal function and survival. Several essential cellular processes such as intracellular trafficking and nuclear tRNA export are thought to ...

It is well known that life expectancy can be expressed as an integral of the survival curve. The reverse that the survival function can be expressed as an integral of life expectancy is also true. 1. Relationship Let e(a) denote remaining life expectancy at age a and let `(a) denote the proportion surviving to age a (the survival function). Then (1) l(a) = e(0) e(a) exp ( − ∫ a

Two hypotheses have been considered in the literature regarding how anuran morphology reduces predation risk: by (1) improving escape swimming performance, or (2) using the tail as a lure to draw predator strikes away from the body of the tadpole. We investigated these hypotheses using a modification of the morphology, performance, and fitness path analysis of Arnold (1983, Am. Zool. 23:347-361...

Abstract: Let {Xn, n=1} be a sequences of i.i.d. random variables with survival function 1 F(x) P[X x] = > . A wavelet linear survival function n F(x) based on X1, X2,..., Xn is introduced as an estimator for n F(x) . We establish that the Lp’-loss (2=r=p′= ∞) of the linear wavelet survival function estimator for a stochastic processes convergence at the rate rs 2 s 1 n (s s 1 /p 1 / p ) ′ − ′+...

BACKGROUND Thyroid function has been associated with breast cancer risk, and breast cancer cell growth and proliferation. It is not clear whether thyroid function affects prognosis following breast cancer but, if so, this could have an important clinical impact. The present study analysed prospectively collected measurements of free tri-iodothyronine (T3), free thyroxine (T4), thyroid-stimulati...
