骨质疏松的预防和饮食

为什么每天喝牛奶还会得骨质疏松？造成骨质疏松的原因不仅是钙的摄入量不足导致的缺钙,维生素C、蛋白质和胶原蛋白的合成发生障碍导致的骨有机基质生成不良才是首发因素。     

A randomized,double-blind,placebo-controlled trial of testosterone gel on body composition and health-related quality-of-life in men with hypogonadal to low-normal levels of serum testosterone and symptoms of androgen deficiency over 6 months with 12 months open-label follow-up

Introduction: The clinical significance of low to low-normal testosterone (T) levels in men remains debated. Aim: To analyze the effects of raising serum T on lean body mass (LBM), fat mass (FM), total body mass, and health-related quality-of-life (HRQoL). Methods: Randomized, double-blind, placebo-controlled study. Men, aged 50–80 years, with serum total T<15 nmol/L and bioavailable T < 6.68 nmol/L, and a Aging Males’ Symptoms (AMS) total score >36, received 6 months treatment with transdermal 1% T gel (5–7.5?mg/day; n =183) or placebo gel (n =179), followed by 12 months open-label with T in all. Results: After 6 months, LBM increased in T- treated patients by 1.28?±?0.15?kg (mean ± SE) and FM decreased by 1.16?±?0.16?kg, with minor changes with placebo (LBM +0.02?±?0.10?kg and FM ?0.14?±?0.12?kg; all p < 0.001, T group vs. placebo). Changes were largely similar across subgroups of age, baseline total testosterone, and baseline BMI. Total HRQoL improved compared with placebo (p < 0.05, T group vs. placebo). Conclusions: Six months 1% T gel improved body composition and HRQoL in symptomatic men with low to low-normal T, with further improvements over the following 12 months.     

East African Population Census 1948 Some Problems of Planning

The effects of nonresponse can be reduced by simulating an increase in the number of recalls. The procedure consists in adding to the addresses of current surveys the nonresponse addresses from similar recent surveys.     

Parameter estimation in nonlinear regression models 1

Fisher information contained in record values, inter-record times and their concomitants from a sample of fixed size is derived in general and explicit expressions are deduced for some specific known bivariate classes of distributions. A comparison between fixed sampling and inverse sampling schemes with equal number of records and concomitants is also carried out. We also consider parameter estimation based on bivariate records and a small simulation study is done.

萨特的"整体性"、"整体化"概念和他的"人学辩证法"

萨特认为,辩证运动来源于个体的多元复合的总体的"整体化","辩证法"应该是在人的个体实践的"整体化"活动中来理解."整体性"是经验可理论的个体实践的多元复合性关系及其结构的总体关联性,它是"整体化"的结果,也是"整体化"运动中具有惰性作用的暂时的调节性因素,它体现着个人的各种关系和结构,是可以通过触景生情的联想而予以把握的."整体化"是人的不断发展的多元复合性关系的实践及其过程,另方面它也是实践场域的运动,并且,这二者是相互规定和制约,使个人及其实践始终面向未来,从而构成历史的辩证法;同时,"整体化"也就是人的最根本的存在.个人是历史的施动者,同时他也是被整体化者.所以在萨特看来,辩证法也就是"人学辩证法".
