The participation of a variety of new actors in social spaces of science and technology policy-making has become an important issue in STS as well as in politics. The field of technology assessment offers an excellent example. The literature refers to procedures creating such multi-actor spaces as “participatory technology assessment” (PTA). They are considered to be one promising way to promot...

Acetate and formate are major fermentation products of Escherichia coli. Below pH 7, the balance shifts to lactate; an oversupply of acetate or formate retards growth. E. coli W3110 was grown with aeration in potassium-modified Luria broth buffered at pH 6.7 in the presence or absence of added acetate or formate, and the protein profiles were compared by two-dimensional sodium dodecyl sulfate-p...

Pancreas transplant alone (PTA) is coming of age for the treatment of selected type 1 diabetic (T1D) patients (1). By restoring endogenous insulin secretion, it eliminates acute diabetes complications and may improve late microvascular complications (1,2). However, the impact of PTA on the recipient’s heart is largely unknown. Here, we report that successful PTA is associated with long-term ame...

Adhesion between fillers and a polymeric matrix is an essential characteristic for mixed-matrix membranes molecular separation to avoid defects cavities that would decrease selectivity. We demonstrate here how solution rheology can be excellent tool identity polymer–filler pairs with strong interaction. The investigated system was polytriazole without hydroxyl functionalization (PTA-OH PTA) ZIF...

PURPOSE To compare the effectiveness and safety of use of the peripheral cutting balloon (PCB) versus standard percutaneous transluminal angioplasty (PTA) for the treatment of hemodialysis-related stenoses. MATERIALS AND METHODS This prospective, randomized multicenter clinical trial included 340 patients with stenotic or thrombosed hemodialysis grafts who were randomized to receive treatment...

BACKGROUND Right ventricular dysfunction has been observed in uremic patients receiving percutaneous transluminal angioplasty (PTA). This prospective study focuses on the impact of tissue Doppler imaging echocardiographic parameters on assessing right ventricle function in uremic patients post PTA of dysfunctional hemodialysis access. METHODS Sixty uremic patients were divided into two groups...

cis-3-(9H-Purin-6-ylthio)acrylic acid (PTA) is a structural analog of azathioprine, a prodrug of the antitumor and immunosuppressive drug 6-mercaptopurine (6-MP). In this study, we examined the in vitro and in vivo metabolism of PTA in rats. Two metabolites of PTA, 6-MP and the major metabolite, S-(9H-purin-6-yl)glutathione (PG), were formed in a time- and GSH-dependent manner in vitro. Formati...

New rhenium(VII or III) complexes [ReO3(PTA)2][ReO4] (1) (PTA = 1,3,5-triaza-7-phosphaadamantane), [ReO3(mPTA)][ReO4]I (2) (mPTA = N-methyl-1,3,5-triaza-7-phosphaadamantane cation), [ReO3(HMT)2][ReO4] (3) (HMT = hexamethylenetetramine), [ReO3(η(2)-Tpm)(PTA)][ReO4] (4) [Tpm = hydrotris(pyrazol-1-yl)methane, HC(pz)3, pz = pyrazolyl], [ReO3(Hpz)(HMT)][ReO4] (5) (Hpz = pyrazole), [ReO(Tpms)(HMT)] (...

Oligonucleotide probes that can be used for non-denaturing fluorescence in situ hybridization (ND-FISH) analysis are convenient tools for identifying chromosomes of wheat (Triticum aestivum L.) and its relatives. New oligonucleotide probes, Oligo-HvT01, Oligo-pTa71-1, Oligo-s120.1, Oligo-s120.2, Oligo-s120.3, Oligo-275.1, Oligo-275.2, Oligo-k566 and Oligo-713, were designed based on the repetit...
