The catalytic co-conversion of glycerol and oleic acid (45/55 wt%) to bio-based aromatics (benzene, toluene, xylenes, bio-BTX) over a technical H-ZSM-5/Al2O3 catalyst in fixed-bed reactor was investigated with special attention deactivation phenomena. spent catalysts after time on stream (TOS) 12 h were regenerated by an ex-situ oxidative treatment remove coke reused for another run. In total, ...
this research is about the political economy of china in central asia. in this research the political & economic interactions affected on chinas political economy in central asia are examined. chinas goal of presence in central asia including political-security, economic and energy goals is described in one part. in another part, the trade relations between china and central asian countries ar...
The voltage-gated sodium channel is the site of action of more than six classes of neurotoxins and drugs that alter its function by interaction with distinct, allosterically coupled receptor sites. Batrachotoxin (BTX) is a steroidal alkaloid that binds to neurotoxin receptor site 2 and causes persistent activation. BTX binding is inhibited allosterically by local anesthetics. We have investigat...
We report herein the synthesis of ¾ substituted benzene sulfonamides linked via phenyl ring to a benzothiazole moiety. The title compounds in the two series namely N-(4-(benzothiazole-2-yl) phenyl) 4- substituted benzene sulfonamides and N-(4-(benzothiazole-2-yl) phenyl) 3- substituted benzene sulfonamides were synthesized by condensing 2-(3/4-aminophenyl) benzothiazole with various...
Introduction: In recent years, many national and international expert groups have considered specific improvements in risk assessment of chemical pollutants. This study considered to assess the risk of workers exposure to air pollutants in an automobile manufacturing in order to evaluate the health risk assessment due to the inhalation exposure. Material and Method: To perform this study, ...

AIMS To determine if the outcomes of intradetrusor botulinum toxin A (BTX-A) injections for the management of refractory overactive bladder (OAB) symptoms are different if performed due to lack of anticholinergic efficacy versus medication intolerability. METHODS Retrospective chart review was performed on all patients undergoing intradetrusor BTX-A (BOTOX®, Allergan Inc., Irvine, CA) injecti...
in recent years many researchers have been focused on interaction of small molecules with dna. dna is generally the primary intracellular of anticancer drugs, so the interaction between small molecules and dna can cause dna damage in cancer cells, blocking the division of cancer cells and resulting in cell death. the flavonoids are a large group of polyphenolic natural products that are widely ...
Edible seaweeds Chondrus crispus, Codium fragile, Himanthalia elongata, Ulva lactuca and Undaria pinnatifida, without any treatment (control seaweeds), were stored at 4 °C for 15, 30, 60, 15 30 days, respectively, until microbial counts exceeded 7 log cfu/g. High pressure processed (HPP) seaweeds, treated 400 or 600 MPa 5 min on day 2 after collection, held 180. At the start of storage, 133 vol...
Background and purpose: Today use of unleaded gasoline is increasing in the world which contain abundant amount of aromatic organic carcinogenic compounds. This study aimed at monitoring the temporal and spatial concentration of benzene and toluene as volatile organic compounds in ambient air in Yazd, Iran. Materials and methods: This research, was carried out in different hours of the morni...
