Combined binary/decimal arithmetic has become an important topic to support decimal and binary applications with high speed and low area. This paper presents a combined binary/decimal fixed-point multiplier design. Since the partial products accumulation stage has the largest area and delay of the multiplier, it is the most significant stage. A novel binary column tree is shared for binary and decimal reduction tree. A comparison between the proposed design and the previously published designs shows a significant decrease in area with almost the same delay as the fastest known design.

Paragangliomas rarely involve the genitourinary tract. We present a case of a paraganglioma arising from the spermatic cord and review the literature on the topic.

Atorvastatin (ATV) was previously shown to improve oxidative stress, inflammation and endothelial dysfunction in several experimental and clinical studies yet other studies have reported a pro-oxidant and damaging effect upon ATV administration. The present study was directed to investigate the effect of ATV pre- and post-treatment in isoproterenol (ISO)-induced cardiotoxicity in rats. Myocardial damage was induced by ISO (5 mg/kg/day, s.c.) for 1 week. ATV (10 mg/kg/day, p.o.) was given for 2 weeks starting 1 week before or after ISO administration. ISO-treated rats showed significant alterations in electrocardiographic recordings, serum creatine kinase-MB (CK-MB) level as well as oxidative stress and inflammatory biomarkers. Moreover, ISO administration resulted in endothelial dysfunction and significant histopathological damage. Pre-treatment with ATV aggravated ISO-induced cardiotoxicity. On the other hand, ATV post-treatment succeeded to significantly improve oxidative stress and inflammatory biomarkers, endothelial dysfunction and myocardial degeneration. These results suggest that ATV might produce a synergistic pro-oxidant effect if given before or along with another pro-oxidant (ISO). Thus, caution should be applied upon the use of statin as a prophylactic therapy for primary cardiovascular disease prevention.

It has been found that NADPH-dependent hydroxylation of dimethylaniline, aniline, p- and o-nitroanisol and lipid peroxidation is inhibited by the tyrosine-copper (II) complex (low molecular weight analog of superoxide dismutase), which is indicative of a possibility of superoxide radicals formation in these reactions. The inhibition of the above-mentioned reactions with Tyr2-Cu2+ is less pronounced or absent, if cumole hydroperoxide is used as cosubstrate instead of NADPH. Differences in the Tyr2-Cu2+ complex effects on the cumule hydroperoxide-dependent xenobiotics hydroxylation and lipid peroxidation catalyzed by various forms of cytochrome P-450, e. g. microsomal, soluble and incorporated into liposomes, have been found. The data obtained suggest that the efficiency of the inhibitory effect of the Tyr2-Cu2+ complex depends on the type of cosubstrates (NADPH, cumole hydroperoxide) and substrates used as well as on the form of cytochrome P-450.

Proper enterocytic proliferation/differentiation, besides providing adequate adherens junctions (AJ) integrity, are responsible for strengthening of the gut barrier that acts as a first line defense against endotoxemia. However, the preferential role of the underlying PI3K/Akt (PKB) axis in triggering enterocytic proliferation/differentiation signaling and AJ assembly is still obscure in sepsis. Additionally, the potential involvement of dipeptidyl peptidase (DPP)-IV in cholestatic sepsis has not yet been reported. Common bile duct ligation (CBDL) insult was performed in adult male Sprague-Dawley rats except for sham operated animals; three doses of vildagliptin (VLD3, 10 and 30 mg/kg/d; p.o) were administered for 10 consecutive days post CBDL. VLD3/10/30 dose-dependently decreased DPP-IV and elevated GLP-1, IGF-1, PI3K, pS473-Akt (PKB), pS9-GSK-3β, pS133-CREB and cyclin-D1. VLD3/10 reduced fever, portal/aortic endotoxin and IgG, body weight loss as well as ileal NF-κB, TNF-α, MPO, TBARS, subepithelial/pericryptal and submucosal collagen deposition, vimentin immunoreactivity, N-cadherin, Zeb1 and pY654-β-catenin but increased E-cadherin, NPSH and colon/spleen indices - effects that were quite the opposite of VLD30. Accordingly, maintaining proper enterocytic proliferation/differentiation and phosphorylation inputs consequent to adequate DPP-IV inhibition is integral to AJ assembly in cholestatic sepsis; however, perturbed signals by excessive suppression of the enzyme activity induce toxic effects manifested as AJ disassembly and EMT, hence gut leakage and overt endotoxemia.
