Directly synthesising dimethyl ether (DME) from CO2 hydrogenation is a promising technique for efficiently utilising as feedstock to produce clean fuel. The main challenges in this process are the low conversion and DME selectivity of catalyst its deactivation over time due sintering, aggregation, coke formation, water adsorption. This study aimed develop dual-functional, halloysite nanotube-su...

Pinellia ternata agglutinin (PTA) is highly homologous to many other monocot mannose-binding lectins which reportedly possess antitumor activities. Its production in silkworm cells has great application potential because the baculovirus expression system can produce post-translationally modified proteins at low cost. In the current study, the pta gene was cloned and expressed in silkworm cells,...

We report the successful treatment of BuddChiari syndrome caused by membranous obstruction of intrahepatic inferior vena cava (MOVC) with large amount of thrombi by balloon angioplasty. A 45-year-old woman developed general malaise and edema of legs. MOVC with large thrombi was diagnosed after MR angiogram and vena cavogram. We performed two-stage percutaneous transluminal angioplasty (PTA) wit...

The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of PTA wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bioreactor design for PTA wastewater treatment. The results of the case study suggests that onestage thermophilic anaerobic reactor ...

A 42-yr-old woman with systemic lupus erythematosus without bleeding diathesis developed a prolonged activated partial thromboplastin time that was not corrected by normal plasma. An inhibitor that acted rapidly and mactivated 0.5 U/mI plasma thromboplastin antecedent (PTA. factor Xl) at a 1 :200 plasma dilution was demonstrated. In addition to a low titer of PTA (<0.01 U/mI). plasma assayed at...

Endovascular treatment strategies for the relief of symptomatic lower extremity PVD secondary to femoropopliteal (FP) artery disease are changing at an unprecedented fast rate. Improved metallic stent designs, novel devices and techniques, and improvements to past therapeutic concepts have recently emerged, providing new and challenging options to the mainstay of percutaneous transluminal angio...

OBJECTIVES This study investigated the applicability of the self-regulatory executive functioning (S-REF) model to performance test anxiety (PTA) in objective structured clinical examinations (OSCEs). Specifically, it examined the relative contributions of metacognitive beliefs, trait worry and attentional control to PTA. METHODS A cross-sectional design was used. Immediately prior to their f...

Science and technology policy is often confronted with issues that are both complex and controversial and which have to be decided upon in a delicate constellation of policy-makers, experts, stakeholders, non-governmental organizations and the public. One attempt to deal with such a complex problem is via citizen involvement. Participatory technology assessment (pTA) already goes back to severa...

BACKGROUND AND PURPOSE The literature contains relatively few reports of distal embolism associated with intervention for intracranial atherosclerotic disease. Our purpose was to evaluate the frequency of thromboembolic events after percutaneous transluminal angioplasty (PTA) or stent placement in this setting by using diffusion-weighted (DW) imaging. METHODS Between October 1999 and January ...

BACKGROUND AND PURPOSE The major goal of acute ischemic stroke treatment is fast and sufficient recanalization. Percutaneous transluminal balloon angioplasty (PTA) and/or placement of a stent might achieve both by compressing the thrombus at the occlusion site. This study assesses the feasibility, recanalization rate, and complications of the 2 techniques in an animal model. MATERIALS AND MET...
