Polychlorinated biphenyls (PCBs) exert a broad range of toxicity via both parent compounds and their metabolites. Our previous study showed that hydroquinone (H2Q) metabolites of PCBs act as cosubstrates for prostaglandin H synthase (PGHS), and are oxidized by this enzyme to corresponding quinones (Q). The goal of this thesis is to illuminate the PGHS-mediated toxicity of lower chlorinated PCBs...

In order to increase the accuracy of diagnosis in lung cancer, analysis concerning cytological and histological correlation was attempted. The present study consists of 106 patients, who were seen during the past approximately five years and underwent radical surgery to remove tumors completely; mere biopsy specimens were excluded. These patients were 63 years old on the average, 78 males and 2...

Reactive oxygen species induce formation of 15-F(2t)-isoprostane (15-F(2t)-IsoP), a specific marker of in vivo lipid peroxidation, which is increased after myocardial ischemia and during the subsequent reperfusion. 15-F(2t)-IsoP possesses potent bioactivity under pathophysiological conditions. However, it remains unknown whether 15-F(2t)-IsoP, by itself, can influence myocardial ischemia-reperf...

Let sq denote the q-ary sum-of-digits function and let P1(X), P2(X) ∈ Z[X] with P1(N), P2(N) ⊂ N be polynomials of degree h, l ≥ 1, h 6= l, respectively. In this note we show that (sq(P1(n))/sq(P2(n)))n≥1 is dense in R. This extends work by Stolarsky (1978) and Hare, Laishram and Stoll (2011).

Introduction Small quantity lipid-based nutrient supplements (SQ-LNS) have been designed to prevent undernutrition, including stunting, wasting and micronutrient deficiencies [1]. A daily 20 g ration of SQ-LNS provides about 110–120 kcal along with protein, essential fatty acids and 22 micronutrients. Studies assessing the impact of SQ-LNS and medium-quantity LNS (MQ-LNS; at ~50 g or ~250-280 k...

Plant isoprenoids represent a large group of compounds with a wide range of physiological functions. In the cytosol, isoprenoids are synthesized via the classical acetate/mevalonate pathway. In this pathway, farnesyl diphosphate (FPP) occupies a central position, from which isoprene units are dispatched to the different classes of isoprenoids, with sterols as the major end products. The present...
