The mannan endo-1,4-β-mannosidase gene man26A from Aspergillus niger CBS 513.88 was optimized according to the codon usage bias in Pichia pastoris and synthesized by splicing overlap extension PCR. It was successfully expressed in P. pastoris using constitutive expression vector pGAPzαA. The recombinant endo-beta-1,4-mannanase could work in an extremely(More)
This meta-analysis was to evaluate the efficacy of current treatment modalities for kaposiform hemangioendothelioma and tufted angioma. A systematic review was performed using PubMed (Medline), Web of Science and Embase for clinical studies. The outcome was measured by pooled response rate with 95% confidence intervals (CIs), together with heterogeneity,(More)
The present study investigated the effect of systemic administration of the GABA(B) receptor agonist, baclofen, on the development and expression of d-methamphetamine (d-MA)-induced place preference in male Wistar rats. Using a biased and 8-day schedule of conditioning, it was found that administration of d-MA (0.5 mg/kg, i.p.) produced significant place(More)
Vascular anomalies are among the most common congenital and neonatal dysmorphogenesis, which are separated into hemangiomas and vascular malformations. They can occur in various areas throughout the body, with 60% being located in the head and neck. The true mechanism of pathogenesis of vascular anomalies is still unclear. Various treatment methods have(More)
BACKGROUND AND PURPOSE Because of the relatively rare and extremely varied clinical presentations, arteriovenous malformations (AVMs) involving the auriculae are technically challenging clinical entities to diagnose and, ultimately, manage. The purpose of our study was to present our initial experience of ethanol embolization in a series of 17 patients with(More)
AIM To study the potential of the psychological dependence of tramadol. METHODS Rats were trained to discriminate 4.0 mg/kg morphine, and to discriminate 0.5 mg/kg methamphetamine (MA) from saline under a fixed-ratio (FR10) schedule of reinforcement. After they acquired the discrimination, different doses of tramadol were used to substitute for training(More)
The effects of cocaine and the cocaine metabolites norcocaine, ecgonine methyl ester, benzoylecgonine and cocaethylene were evaluated in conscious squirrel monkeys for their effects on blood pressure and heart rate. Norcocaine, ecgonine methyl ester and benzoylecgonine are produced in vivo following cocaine use. Cocaethylene is produced in vivo following(More)
E6 and E7 oncoproteins from high-risk human papillomavirus (HPV) can transform cells in tissue culture and induce tumors in vivo by abrogating the cell-cycle checkpoint. To investigate the impact of HPV16 E6 and E7 on the cell-cycle regulatory machinery in oral epithelial cells, normal human oral epithelial cells were transfected with HPV16 E6 and E7 open(More)
OBJECTIVE To evaluate the use of an allogenic acellular dermal matrix (ADM) as an interpositional graft to prevent Frey's syndrome after parotidectomy. METHOD We studied a total of 168 patients with benign parotid gland tumours, including 89 patients with pleomorphic adenoma; 45 with Warthin tumour; 17 with basal cell adenoma; and 17 with miscellaneous(More)
OBJECTIVE To evaluate the efficacy and safety of intralesional injection of pingyangmycin for the treatment of microcystic lymphatic malformations (LMs) in the tongue. METHODS Eighteen patients with tongue microcystic LMs were treated with intralesional injection of pingyangmycin. The concentration of the drug was 1 mg/mL with an addition of(More)
