PURPOSE Frozen Shoulder Syndrome is a fibrosis of the shoulder joint capsule that is clinically associated with Dupuytren's disease, a fibrosis of the palmar fascia. Little is known about any commonalities in the pathophysiology of these connective tissue fibroses. β-catenin, a protein that transactivates gene expression, and levels of IGF2 mRNA, encoding insulin-like growth factor-II, are elev...

BACKGROUND Intraoperative consultations in neuropathology are often assessed by smear preparations rather than by frozen sections. Both techniques are standard practice for light microscopic examination on site, but there is little data comparing these techniques in a telepathology setting. METHODS Thirty cases of brain tumours submitted for intraoperative consultation at our institution betw...

The quantification of fibrotic tissue is an important task in the analysis of cardiac remodeling. The use of established fibrosis staining techniques is limited on frozen cardiac tissue sections due to a reduced color contrast compared to paraffin embedded sections. We therefore used FITC-labeled wheat germ agglutinin (WGA), which marks fibrotic tissue in comparable quality as the established p...

Background The aim of this study was to investigate the effect of applying the 1-mT magnetic field (MF) in the ovarian tissue vitrification. MaterialsAndMethods Ovaries of 6-8 week-old Naval Medical Research Institute female mice randomly were divided into 5 groups: V1: Ovaries that immediately after leaving of the mice body, were examined histologically (control group), V2: Ovaries that withou...

Frozen tissue specimens are the gold standard for molecular analysis. However, snap freezing presents several challenges regarding collection and storage of tissue, and preservation of histological detail. We evaluate an alternative preservation method, ethanol fixation followed by paraffin embedding, by analyzing expression profiles of microdissected cells on Affymetrix oligonucleotide arrays ...

UNLABELLED Frozen section examination is aimed at making a preoperative diagnosis, determining the benign or malignant nature of a breast lesion, but also the most suitable surgical procedure. The sensitivity and specificity of this method and the causes of discrepancies were analyzed in a retrospective study of 2 177 breast lesions. METHOD 1,150 frozen sections from 2,177 breast lesions were...

Frostbite is a local freezing injury that can cause tissue loss. Historically, it has been a disease of wars, but it is a hazard for anyone who ventures outdoors in cold weather. Frozen tissue is damaged both during freezing and rewarming. Frozen tissue is numb. Rewarming causes hyperemia and is often painful. Blisters and edema develop after rewarming. Hard eschar may form with healthy tissue ...

Gene expression microarrays are the most widely used technique for genome-wide expression profiling. However, microarrays do not perform well on formalin fixed paraffin embedded tissue (FFPET). Consequently, microarrays cannot be effectively utilized to perform gene expression profiling on the vast majority of archival tumor samples. To address this limitation of gene expression microarrays, we...
