The Aim Of The Study: The aim of the study was to validate the value of E-cadherin and -catenin expression and to test an alternative prognostic marker, epithelial membrane antigen (EMA).
Material And Methods: Forty-nine consecutive patients with primary stage T1 non-muscle-invasive bladder cancer (NMIBC) were enrolled in this study. Tissue specimens were stained with the following mouse anti-human antibodies: anti-E-cadherin, anti--catenin, and anti-EMA.
Background: Despite progress in diagnostic procedures, clinical diagnosis is not always confirmed by an autopsy. An autopsy is a valuable tool in evaluating diagnostic accuracy.
Objectives: The aim of the study was to compare clinical diagnoses of immediate causes of death with autopsy findings in patients with hematological malignancies or aplastic anemia.
Microscopic differentiation between muscularis mucosae (MM) and muscularis propria (MP) of the bladder in the material obtained during transurethral resection (TUR) remains difficult. The study was aimed at determination of the usefulness of immunohistochemical staining in this context. Forty-seven TUR specimens were stained with 5 mouse anti-human antibodies: anti-desmin, anti-filamin, anti-type IV collagen, anti-smoothelin, and anti-vimentin.

These products contain strongly anti-angiogenic chemical compounds which could not be indifferent to the developing fetus. In the present work we evaluated the effect of feeding pregnant and lactating mice American cranberry extract (daily dose 0.

Many herbal medicines, among them extracts from plants of Rhodiola genus, have antimicrobial, anti-inflammatory, and immunostimulatory properties owing to their polyphenol content; they may, however, affect fetal development due to their antiangiogenic properties. The aim of this study was to explain whether daily feeding pregnant and lactating mice with 20 mg/kg Rhodiola kirilowii aqueous (RKW) or 50% hydro-alcoholic (RKW-A) extracts, or 0.

Objective: To identify MM- and MP-specific antigens that could be of potential value for staging of urothelial carcinoma in a pilot study.
Method: The expression of 12 protein antigens in 11 human bladder specimens was examined.
Staging and grading of bladder cancer have a substantial impact on patients' prognosis. However, due to the relatively low quality and quantity of specimens from transurethral resection (TUR), initial histopathological examination may not be fully reliable. The aim of this study was to assess the repeatability of staging and grading in post-TUR and post-radical cystectomy (RC) specimens.

The aim of this study was to evaluate contribution of innate, humoral mechanisms of nonspecific immune response in the myocardium subjected to infarction. Complement components and inhibitors were analyzed.

Ongoing development of our civilization is accompanied by a marked increase of incidence of cardiovascular diseases and cardiovascular mortality. Ischemic heart disease with its extreme form - myocardial infarction - is one of the main problems of modern medicine. Despite much research devoted to this disease entity, its pathomechanism remains incompletely understood.

Its frequency is estimated to be approximately 1% and a large part of the percentage is accounted for by the regression of pulmonary metastases in the course of clear type of RCC treatment.

Since Rho GTPases are key factors in cell proliferation, polarity, cytoskeletal remodeling and migration, the aberrant function of their regulators may lead to cell transformation. One subgroup of these proteins is the DLC family.

Osteosarcoma (OS) remains the most common malignancy among orthopaedic neoplasms. Despite advanced surgical techniques and attempts to use second-line chemotherapy, 5 year overall survival in OS patients is still reported to be as low as 60-70%. Progression to metastatic disease is the main cause of treatment failures.

Mice that inhaled 10% solution of 3-undecanone(3-on) or 1% solution of 2-undecanone propylene acetal (Acpr2) for 3 days after tumor cells implantation, presented lower neovascular response measured by tumor-induced cutaneous angiogenesis test (TIA) and lower tumor VEGF content in 5-days tumors, than non-inhaled controls. Other substances presented various effects on tumor VEGF concentration and angiogenesis.

The heart develops from 2 areas, the so-called "heart fields", which differ in the expression of various genes and in sensitivity to certain substances (for example retinoid acid). Heart fields are the source of cardiomyocytes and endocardial endothelial cells for the developing heart tube.

Despite considerable advances in that field, graft rejection is still an important clinical problem. The reaction of the graft recipient to an organ presenting foreign antigens is dependent on complex immune mechanisms, involving both acquired and congenital immune responses.

The aim of this work was to study the in vivo and in vitro effects of aqueous and 50% hydro-alcoholic extracts of RK rhizomes on some parameters of cellular immunity in H-2d mice and rats. We show for the first time that in vitro both extracts stimulated granulocyte activity and increased lymphocyte response to mitogens, and in vivo they enhanced the ability of lymphocytes derived from parental strain mice fed R.

The role of FH in colon cancer has not yet been examined. Here, we studied immunocytochemically FH/FHL expression in tumor samples derived from 40 patients, with both primary colon adenocarcinoma and metastatic foci in the liver.
