(1) Explants of renal cortex from 7-day mice or 5-day rats were reared on plasma clots, in the presence or absence of chick embryo metanephros. (2) The size of outgrowth, estimated after 48 h, was similar for renal cortex of both species. When reared in chick embryo extract in the presence or absence of metanephros, the outgrowth estimated after 48 h was 2-08 ±0-092 greater than that of the ini...

Because it detects discrete changes in tissue density, ultrasound allows an early diagnosis of physiologic changes, especially when dealing with subclinical changes. aimed to evaluate the use quantitative analysis gray scale images ovine testicles as a method for testicular caused by heat stress. Testicles from ten were insulated and then evaluated regarding echogenicity, echotexture, anatomica...

OBJECTIVE Lymphoedema involves swelling, especially in the subcutaneous tissues. For lymphoedema management to be successful, it is necessary to remove the interstitial fluid. Subcutaneous echogenicity may be associated with interstitial fluid, but echogenicity is not an indicator for the evaluation of management because we do not directly compare echogenicity with the interstitial fluid. We ai...

Ultrasonography (US) is useful for visual detection of edematous tissues to assess subcutaneous echogenicity. However, visualization of subcutaneous echogenicity is interpreted differently among operators because the evaluation is subjective and individual operators have unique knowledge. This study objectively assessed leg edema using US with a gel pad including fat for normalization of echoge...

OBJECTIVE To evaluate in a systematic review and meta-analysis model the effect of statin therapy on carotid plaque echogenicity assessed by ultrasound. METHODS We have systematically searched electronic databases (PubMed, MEDLINE, EMBASE and Cochrane Center Register) up to April, 2015, for studies evaluating the effect of statins on plaque echogenicity. Two researchers independently determin...

Erythropoietin (EPO), known for its role in erythroid differentiation, has been shown to be an important growth factor for brain and heart. EPO is synthesized by fibroblast-like cells in the renal cortex. Prompted by this anatomical relationship and its significant impact on the maturation process of brain and heart, we asked whether EPO could play a role during the development of renal cortex....

introduction: topographic anatomy of the tendons and ligaments in healthy cases provides a normal atlas to diagnose abnormalities. the aim of this study was to provide ultrasonography description of the palmar tendons and ligaments of the anatoly donkey. methods: the metacarpal regions of 6 healthy anatoly donkeys were prepared for ultrasonography and divided to 6 levels (1a, 1b, 2a, 2b, 3a, 3b...

OBJECTIVE Two methods to assess liver echogenicity were compared. METHODS Liver/kidney echogenicity ratio was measured in 41 persons with the ultrasound software and visually graded by two radiologists and a radiographer. These echogenicity ratios and grades were related to risk factors for fatty liver and to liver enzyme levels. RESULTS These determinants explained 55% of the radiologists'...
