In the current petrochemical market, global demand for aromatics, especially benzene, toluene, and xylenes (BTXs), has increased sharply. The methanol-to-aromatic conversion (MTA) over ZSM-5 is among most promising routes to satisfy this ever-growing demand. work, we show that high-pressure operation during MTA leads a large increase in aromatic selectivity while enhancing stability on-stream. ...

OBJECTIVE To investigate the potential differential effects of selective endothelin (ET) A and dual ET-A/B receptor blockade in patients with chronic heart failure. METHODS Nine patients with chronic heart failure (New York Heart Association class II-III) each received intravenous infusions of BQ-123 alone (selective ET-A blockade) and combined BQ-123 and BQ-788 (dual ET-A/B blockade) in a ra...

Despite significant progress in hepatitis C (HCV) treatment, global viral eradication remains a challenge. An in-depth map of its genome diversity within the context of structural and immunological constraints could contribute to the design of pan-genotypic antivirals and preventive vaccines. For such analyses, extensive information is only available for the highly prevalent HCV genotypes (GT) ...

OBJECTIVES We sought to study the safety, feasibility and efficacy of selective suction and pressure-regulated retroinfusion to protect against myocardial ischemia in patients undergoing normal risk and high risk balloon angioplasty. BACKGROUND In a pig model of acute myocardial ischemia it was previously shown that use of selective suction and pressure-regulated retroinfusion was able to sub...

Glaucoma is characterized by a loss of retinal ganglion cells (RGC) which is associated with a decrease of visual function. Neuroprotective agents as a new therapeutic strategy could prevent the remaining neurons from apoptotic cell death. Previous studies have shown the involvement of the Cyclooxygenase (COX)-2 signalling in the apoptotic death of neurons. Herein we investigated the neuroprote...

what to look for in abbas abad pool? a lake in middle of the forest on the mountain heights with an encircled building with waters and a garden ashore? why are the trees cut and used to build a garden? and what is the purpose of placing a lake on a dominant and deep valley over the khazar sea. today, green trees are grown in abbas abad garden and no sign of landscaping or water features can be ...

We investigated the relevance of selectivity for a given alpha-1-adrenoceptor subtype for in vivo uroselectivity of several alpha-1-adrenoceptor antagonists (alfuzosin, doxazosin, prazosin, tamsulosin, terazosin and 5-Me-urapidil). Comparison of the affinities of these alpha-1-adrenoceptor antagonists at the cloned alpha-1a, alpha-1b and alpha-1d-adrenoceptor subtypes revealed that tamsulosin a...
