OBJECTIVE To phenotypically characterize cytotoxic T-lymphocytes (CTLs: Perforin+ and TIA-1+ phenotypes) and to study the interactions with cell adhesion molecules (CAMs) in dilated cardiomyopathy (DCM). BACKGROUND DCM is linked to intramyocardial inflammation, being characterized by T-lymphocytic infiltration and CAMs abundance. However, the pathogenic significance of increased CD3+ lymphocy...

background: nowadays use of specific antivenin for latrodectism is considered as the most effective treatment in the world. this study was undertaken to investigate the efficacy of specific antivenom against histopathological complications caused by latrodectus dahli venom on liver, heart and kidneys tissues within 72 h. methods: two groups were selected, each one contained 6 male new zealand r...

UNLABELLED Colloid cysts are rare congenital, intracranial neoplasms, commonly located in the third ventricle. Colloid cysts are endodermal congenital malformations. The cysts commonly range in size from 1-2 cm in diameter, although large cysts >3 cm in size have been reported. The components of the cyst include an outer fibrous capsule over an inner epithelium. The epithelium is usually a sing...

BACKGROUND AND PURPOSE Creatine kinase-MB (CK-MB) increases in some patients with stroke, with no clear evidence of an acute coronary syndrome. Its elevations have been suggested to represent a biological marker for stroke-related myocardial injury. Troponin T has superior sensitivity and specificity to CK-MB in revealing minor myocardial injury. Therefore, we studied troponin T levels after st...

BACKGROUND Oxidative stress is the major etiopathological factor in adriamycin-induced cardiotoxicity. Relatively low amounts of endogenous antioxidant makes the heart vulnerable to oxidative stress-induced damage. Chronic oral administration of garlic has been reported to enhance the endogenous antioxidants of heart. We hypothesized that garlic-induced enhanced cardiac antioxidants may offer p...

time after HT (R = -0.49; P = .0001). The ROC curve of hs-TnT for detecting AR was 0.682 (95%CI, 0.54-0.81; P = .01). A hs-TnT concentration < 17 ng/L ruled out AR with a sensitivity and a negative predictive value of 100%, but a specificity of 13% (Table 2); there were 29 true negatives for AR with hs-TnT < 17 ng/L. In a mixed-effects logistic regression model, the hs-TnT values were log trans...

Infection with the protozoan parasite Trypanosoma cruzi leads to acute myocarditis that is accompanied by autoimmunity to cardiac myosin in susceptible strains of mice. It has been difficult to determine the contribution of autoimmunity to tissue inflammation, because other inflammatory mechanisms, such as parasite-mediated myocytolysis and parasite-specific immunity, are coincident during acti...

Serum cardiac enzyme levels (CK, LDH, SGOT) were estimated and the ECG recorded for 4 days following admission of 288 patients (Group I) to a stroke intensive care unit. Sixty-four of these patients, subsequently found not to have strokes, served as controls. Mean serum levels of all 3 cardiac enzymes were elevated in 8% of the 224 patients with stroke. The mean serum enzyme levels in patients ...

This is a report on the anatomical findings of 6 cases of typical Ebstein's anomaly found in a review of 1300 autopsy specimens. In addition 2 cases with pulmonary atresia and 1 with atresia of the malformed tricuspid valve showing morphologically similar anomalies were found, as well as 29 cases with tricuspid valvular dysplasia (21 of them coexisting with pulmonary atresia with intact ventric...

It has been found that the pulmonary veins and adjacent left atrial posterior wall (LAPW) are deeply involved in both the initiation and maintenance of atrial fibrillation (AF), and the identification of these high-risk sites has aroused great interest in investigating their histopathologic substrate. We used light and conventional electron microscopy to evaluate the differential myocyte and in...
