BACKGROUND Early manifestations of pediatric inflammatory bowel disease (IBD) can be relatively nonspecific. Initial mucosal biopsies may not be conclusive, delaying the diagnosis until subsequent biopsies demonstrate typical histologic features of IBD. We hypothesized that certain inflammatory cell types may be utilized as early histologic indicators of IBD in children. METHODS A retrospecti...

BACKGROUND The seven categories of the Stanford Faculty Development Program (SFDP) represent a framework for planning and assessing medical teaching. Nevertheless, so far there is no specific evaluation tool for large-group lectures that is based on these categories. This paper reports the development and psychometric validation of a short German evaluation tool for large-group lectures in medi...

Abstract There is a relationship between antioxidant activity and ageing stability of beer. The high-throughput capacity assays ORAC FRAP, which rely on specific reaction mechanisms, are validated as an addition to the established ESR-ST method with focus hop-derived antioxidants. Beers were brewed systematic variations in hop variety, product, hopping regime (late hopping) achieve sample beers...

OBJECTIVE The goal of the present study was to investigate the effects of 5-lipoxygenase (5-LOX) inhibition, alone and with cyclooxygenase (COX) inhibitors, on inflammatory parameters and apoptosis in ischemia/reperfusion (I/R)-induced myocardial damage in rats. For this purpose, zileuton, a selective and potent inhibitor of 5-LOX, resulting in suppression leukotriene production, was used. ME...

background and aims. the aim of this study was to evaluate the possible effects of obesity on the local (salivary) and systemic tnf-α and il-6 levels in patients with chronic periodontitis (cp). materials and methods. this study included 88 subjects assigned to four groups of 22 subjects each, as follows: group o+p+ (patients with obesity and cp), group o-p+ (patients with normal weight and cp)...

The least cardinal λ such that some (equivalently: every) compact group with weight α admits a dense, pseudocompact subgroup of cardinality λ is denoted by m(α). Clearly, m(α) ≤ 2. We show: Theorem 3.3. Among groups of cardinality γ, the group ⊕γQ serves as a “test space” for the availability of a pseudocompact group topology in this sense: If m(α) ≤ γ ≤ 2 then ⊕γQ admits a (necessarily connect...
