Benzene, toluene và xylene (BTX) là thành phần chính của xăng dung môi được sử dụng rộng rãi trong công nghiệp. Do có khả năng hòa tan nước nên BTX cũng xem một những hợp chất gây ô nhiễm phổ biến. Dòng vi khuẩn Rhodococcus sp. XL6.2 phân lập từ hệ thống xử lý thải phòng thí nghiệm hủy hiệu quả BTX. Nghiên cứu này thực hiện nhằm tìm mang phù để tồn trữ làm cơ sở cho việc sản xuất chế phẩm sinh ...

Abstract The valorization of biomass-derived molecules into commodity chemicals is important for the transition to renewable feedstocks. model platform molecule 2,5-dimethylfuran (2,5-dmf) can be converted value-added aromatics such as benzene, toluene, and xylenes (BTX) over zeolite catalysts. To explore role acid site(s) in BTX selectivity, gallium has been isomorphously substituted framework...

Purpose To assess the effectiveness and safety of botulinum toxin A (BTX-A) at different dosages for overactive bladder (OAB). Materials and Methods The MEDLINE, EMBASE, and Cochrane Controlled Trials Register databases were searched through November 3, 2016 to identify relevant randomized controlled trials (RCTs). Results Eleven studies were identified in this meta-analysis. Compared with ...

Dual energy X-ray absorptiometry (DXA), histomorphometry and X-ray microtomography (microCT) were used to assess effects of risedronate and testosterone in a combined rat model of orchidectomy (ORX) and local paralysis induced by botulinum neurotoxin (BTX). Four groups of mature rats were studied for 1 month: SHAM operated; ORX and right hindlimb immobilization (BTX); ORX+BTX+risedronate or tes...

BACKGROUND Wrist blockage of median and ulnar nerves before treatment of palmar hyperhidrosis with botulinum toxin (BTX-A) reduces discomfort and improves accuracy of BTX-A injections, but can be associated with mechanical/chemical injury. OBJECTIVES We sought to compare locoregional anesthesia of median and ulnar nerves using conventional 25-G x 0.50 x 13 mm gauge needle with short 30-G x 0....

BACKGROUND We aimed to study the curative effects of botulinum A toxin (BTX-A) on the treatment of post-herpetic neuralgia (PNH). METHODS We enrolled 58 PNH patients and treated them with hypodermic injection of BTX-A in Xiangyang No.1 People's Hospital, Hubei University of Medicine, Hubei, China. We measured and compared the Visual Analog Score (VAS), Neuropathy Pain Scale (NPS), Quality of ...

The Front Cover shows a symbolic rocket. main structure of the rocket represents ZSM-5 zeolite, and boosters represent added Ga Cr species, respectively. This picture means that propane is rapidly converted into propene hydrogen on modified then BTX aromatics. In their Full Paper, B. Xu et al. introduced to Ga/ZSM-5 catalyst by tuning impregnation sequence amount. Plenty Cr3+ species strong int...

While chewing and grinding movements have been observed in amphetamine addicts, recognition and management of this problem have rarely been highlighted. Botulinum toxin (BTX) has previously been demonstrated to be effective for bruxism associated with movement disorders, such as cranial-cervical dystonia. However, there is little information on its use in tardive bruxism. Here we report an amph...

The most successful alternative to traditional surgery for ocular muscle spasm treatment is the intramuscular injection of botulinum toxin (BTX), which allows maintenance dynamics and absence scars. However, main BTX disadvantage its nonpermanent effect. A possible way overcoming this obstacle could be represented by enzymatic using plant toxins known as ribosome-inactivating proteins (RIPs). I...
