Identification on protein folding types is always based on the 27-class folds dataset, which was provided by Ding & Dubchak in 2001. But with the avalanche of protein sequences, fold data is also expanding, so it will be the inevitable trend to improve the existing dataset and expand more folding types. In this paper, we construct a multi-class protein fold(More)
OBJECTIVE To investigate plasma hydrogen sulfide (H₂S) levels and cystathionine-gamma- lyase (CSE) and cystathionine-beta-synthase (CBS) mRNA expression in the lung tissues in asthmatic rats and to explore the roles of endogenous H₂S, CSE and CBS system in the pathogenesis of asthma. METHODS Thirty male Sprague-Dawley rats (age 5 to 7 weeks) were randomly(More)
OBJECTIVE To study the expression of signal transducer and activator of transcription 6 and its mRNA in rat asthma model and the modulatory effect of dexamethasone (DXM). METHODS Thirty male SD rats were randomly divided into three groups: the control group, asthma group and DXM group. The rats in each group were sacrificed 24 h after the last challenge.(More)
Population genetic data of 21 autosomal short tandem repeats (STRs) were obtained in a sample of 106 unrelated healthy individuals of Bai ethnic minority born in the Dali Bai Autonomous Prefecture in Yunnan Province. We observed 138 alleles with corresponding allelic frequencies ranging from 0.005 to 0.575. The genotypic frequency distributions at those STR(More)
A novel method for the determination of trace amounts of mercury in sediments by sequential injection cold vapor atomic fluorescence spectrometry coupled with microwave assisted digestion was developed in this paper. Satisfactory results were found when the digestion was carried out at 140 degrees C for 5 min by using 10% HCl-50% HNO3- 40% H2O or 30%(More)
OBJECTIVE To explore a simple and inexpensive method or procedure for establishing primary culture and purification of olfactory ensheathing cells (OECs) from the adult rat olfactory bulbs. METHODS The OECs were dissociated from the first two outer layers of the olfactory bulbs of the adult Sprague-Dawley rat (2.5 months old), cultured in DMEM/F12(More)
