The results of algorithmic approbation the technique polarization tomography digital histological study age damage to myocardium and lung tissue based on reconstruction linear birefringence maps are presented. Relationships between temporal change in magnitude statistical moments 1-4 orders characterizing distribution degree crystallization sections duration were determined. Established time in...

The effects of constant light and dark exposure of pubertal male rats on the pituitary-gonadal axis and thyroid activity were studied. The indices of thyroid activity were weight of the thyroid gland, estimation of serum levels of thyroxine (T4) by radioimmunoassay (RIA) technique and histological studies of the thyroid gland. The indices of gonadal activity chosen were weight and histological ...

Confocal laser endomicroscopy (CLE) is a new technique, which allows subsurface histological diagnosis at a cellular and subcellular level in vivo and could provide histological diagnosis during endoscopic examination. Up to now histological examination of the tissue sample is the only definitive way of diagnosis and monitoring organ rejection after transplantation. In case of pancreas transpla...

OBJECTIVE To determine whether preoperative breast MRI is more useful in patients according to their breast density, age, menopausal status, and biopsy findings of carcinoma in situ. MATERIAL AND METHODS We retrospectively studied 264 patients treated for breast cancer who had undergone mammography, ultrasonography, and MRI. We compared the size of the tumor on the three techniques and the se...

The generation and analysis of vascular lesions in appropriate animal models is a cornerstone of research into cardiovascular disease, generating important information on the pathogenesis of lesion formation and the action of novel therapies. Use of atherosclerosis-prone mice, surgical methods of lesion induction, and dietary modification has dramatically improved understanding of the mechanism...

Background Chronic kidney disease is a global health concern, its detection and diagnosis in earlier stages is also a great challenge that can alleviate this burden. Kidney biopsy is important to establish histopathological patterns. But, it is invasive. We aimedto evaluate the correlation of renal resistive index (RI) measured by Doppler ultrasound with the prog...

OBJECTIVES To develop a technique for automatic inflation of a percutaneous transluminal coronary angioplasty (PTCA) balloon, with continuous measurement of the balloon pressure and volume; to validate the technique for determining the mechanical characteristics of coronary arteries. METHODS During necropsy examination of the hearts of nine patients, 17 coronary artery samples were obtained f...

In pathology, histological examination of the "gold standard" to diagnose various diseases. It has contributed significantly toward identifying the abnormalities in tissues and cells, but has inherent drawbacks when used for fast and accurate diagnosis. These limitations include the lack of in vivo observation in real time and sampling errors due to limited number and area coverage of tissue se...

abstract somatic embryogenesis is a new approach to in vitro plant propagation. this technique is based on stem cell obtain and its differentiation to a complete plant. this is affected by components of media culture. so, the effects of ms, b5 and nl media on carrot petiole somatic embryogenesis investigated via histological experiment. to do this, carrot petioles (with 1 cm dimension) cultured...
