Organ weight is one of the most sensitive drug toxicity indicators, and its changes often precede morphological changes. So far, no background data about organ weight and its coefficient in SD rats at different weeks of age have been reported in China. The aim of this study was to summarize and analyze the change trends of organ weight and organ weight coefficients in SD rats at different weeks...

Birth Weight and Retinal Vascular Changes To the Editor: Liew et al1 describe an association between low birth weight and narrower retinal arterioles in middle-aged-to-older adults in the Atherosclerosis Risk in Communities Study. These data constitute an important contribution to the current literature on the use of retinal image analysis in hypertension research. Nevertheless, the significanc...

background: noise pollution is considered as a stressful factor in every day’s life of the industrial world. the present study was designed to investigate the probable effects of different time exposure of noise stress on histomorphometric changes of adrenal gland, plasma cortisol and body weight of the rat.   methods: sixty adult male wistar rats were divided into two series of short time nois...

This study was conducted to estimate the genetic parameters influencing egg quality in Khorasan Razavi native fowl. (Co)Variance components were estimated by the Bayesian statistical method via Gibbs sampling in GIBBS3F90 software. 1000 eggs (28-29 weeks old) were collected from 775 hens of the ninth generation of Khorasan-Razavi Province native fowl breeding center. External (egg weight,specif...

Objective(s): In veterinary medicine, zeolites are used as toxin binder in animal feed, ammonia purification of aquatic pools, animal smell and moisture control. This study investigated on the risk assessment of nano zeolite on development of embryonic chicken models, anomalies, tetratogenic and embryotoxic effects. Methods: Eggs (120 = n) were accidentally di...

S a part of the record of performance studies with Milking Shorthorn steers at the U.S.D.A. Research Center, Beltsville, Maryland, various body measurements of the steers were taken on foot before slaughter. These body measurements were taken to determine whether there exists any association between the measures themselves and between them and certain performance characters. These relationships...

Let F be a finite field. A multiset S of integers is projectionforcing if for every linear function φ : F → F whose multiset of weight changes is S, φ is a coordinate projection up to permutation of entries. The MacWilliams Extension Theorem from coding theory says that S = {0, 0, . . . , 0} is projection-forcing. We give a (super-polynomial) algorithm to determine whether or not a given S is p...

Objective. Develop an experimental model of liver cirrhosis and describe pathomorphological changes in organs tissues laboratory animals. Materials methods. Liver was simulated on 11 sexually mature Wistar male white rats. The control group consisted 12 healthy Acute toxic injury resulting induced by intraperitoneal injection 50% tetrachloromethane (CCl 4 ) solution olive oil the first day expe...

CONTEXT Patients receiving adjuvant chemotherapy for breast cancer have a tendency to gain weight. This tendency has determining factors not completely defined and an unknown prognostic impact. OBJECTIVE To evaluate weight change during chemotherapy for breast cancer in a defined population and to identify its predisposing factors and possible prognostic significance. DESIGN Observational, ...

OBJECTIVE To examine associations between perceived weight discrimination and changes in weight, waist circumference, and weight status. METHODS Data were from 2944 men and women aged ≥50 years participating in the English Longitudinal Study of Ageing. Experiences of weight discrimination were reported in 2010-2011 and weight and waist circumference were objectively measured in 2008-2009 and ...
