Wheat, rye, and barley proteins induce celiac disease, an autoimmune type of gastrointestinal disorder, in genetically susceptible persons. Because the disease may be underdiagnosed, we estimated prevalence tested hypothesis that assays for serum autoantibodies can used to detect untreated positive findings correlate with specific HLA haplotypes.

This study was designed to assess the epidemiology, characteristics, and outcome of cardiac sarcoidosis (CS) in Finland. We identified retrospect all adult (>18 years age) patients diagnosed with histologically confirmed CS Finland between 1988 2012. A total 110 (71 women) 51±9 age (mean±SD) were found followed up for events end 2013.

As a source of transforming growth factor beta1 (TGF-beta1), mast cells have been implicated as potential effector in many pathological processes. However, the mechanisms by which express, secrete, and activate TGF-beta1 remained vague. We show here means RT-PCR, immunoblotting, immunocytochemistry that isolated rat peritoneal synthesize store large latent their chymase 1-containing secretory granules. Mast cell stimulation degranulation results rapid secretion TGF-beta1, is converted 1 into...

Background: Symptomatic high-grade atrioventricular block (AVB) is the most common and often only presenting manifestation (lone AVB) of cardiac sarcoidosis. Implantation an intracardiac cardioverter defibrillator instead a pacemaker recommended, but true risk fatal arrhythmia, one incident to lone AVB in particular, remains poorly known. Methods: We used Myocardial Inflammatory Diseases Finland Study Group Registry analyze presentations, left ventricular (LV) function, therapy, arrhythmias...

Abstract Objective The aim was to clarify how families with physically and/or intellectually disabled children cope, what kind of coping strategies they use and the good poor capacities differ. Methods parents eight (aged 8–10 years) physical intellectual disability were interviewed twice, data elicited in these interviews analysed qualitatively using grounded theory method. Results Information acceptance, family co‐operation social support related most frequently used. Half seemed have...

Objective Cardiac mast cells participate in myocardial dysfunction, but the mechanisms are presently unknown. Design By examining spontaneously hypertensive rats (SHRs) during their entire lifespan, we attempted to define role of induction cardiac hypertrophy and transition heart failure. Methods results contrast normotensive littermates, hearts newborn SHRs already contained cells. In prehypertensive (2-week-old) SHRs, increased expression c-kit soluble stem cell factor correlated with an...

ABSTRACT Objectives: Congenital chloride diarrhea (CLD) is a rare, autosomal recessive disorder of intestinal Cl − /HCO 3 exchange caused by mutations in the SLC26A3 gene and characterized persistent rich from birth.

Background Cardiac sarcoidosis (CS) and giant cell myocarditis (GCM) share many histopathologic clinical features. Whether they are parts of a one‐disease continuum has been discussed. Methods Results We compared medical record data 351 CS 28 GCM cases diagnosed in Finland since the late 1980s followed until February 2018 for composite end point cardiac death, aborted sudden heart transplantation. Heart failure was presenting manifestation 50% versus 15% ( P <0.001), high‐grade...

Background Data from in vitro studies suggest that both chymase and ACE contribute to the local generation of angiotensin (Ang) II heart. The enzyme kinetics under vivo conditions are unclear. We thus studied Ang by cardiac tissue presence interstitial fluid (IF) contains a variety naturally occurring protease inhibitors. Methods Results I was incubated with heart homogenate IF.

OBJECTIVE: To evaluate social maturation and psychiatric morbidity in young adults treated for epilepsy during their childhood. METHODS: Eighty one (43 women, 38 men, mean age 22.3 years) with childhood were interviewed about development symptoms. The results compared those from 211 randomly selected controls (106 105 23.2 years). RESULTS: Compared the patients had more often not succeeded passing normal comprehensive school (20% v 2%) or left at secondary level (53% 46%) remained without...

Abstract Secretory granules exocytosed from rat serosal mast cells bind low density lipoprotein (LDL), and on being phagocytosed by macrophages, carry the bound LDL into these (Kokkonen, J. O., Kovanen, P. T. (1987) Proc. Natl. Acad. Sci. U.S.A. 84, 2287-2291). The binding of to is mediated through interactions between apolipoprotein B (apoB) component heparin proteoglycan granules. Here we report how degradation apoB neutral proteases affects granule-mediated uptake cultured mouse...

The uptake of low density lipoprotein (LDL) by cultured mouse macrophages was markedly promoted isolated rat mast cell granules present in the culture medium. granule-mediated LDL enhanced rate cholesteryl ester synthesis macrophages, result being accumulation esters these cells. Binding to essential for process prevented treating with avidin or protamine chloride 1,2-cyclohexanedione, all which inhibit binding granules. Inhibition granule phagocytosis cytochalasin B also abolished LDL....

Because bradykinin (BK) appears to have cardioprotective effects ranging from improved hemodynamics antiproliferative effects, inhibition of BK-degrading enzymes should potentiate such actions. The purpose this study was find out which are responsible for the degradation BK in human plasma. Human plasma healthy donors ( n = 10) incubated with presence or absence specific enzyme inhibitors. At high (micromolar) concentrations, mostly (>90%) degraded by carboxypeptidase N (CPN)-like...
