An exopolysaccharide (EPS)-producing strain YW11 isolated from Tibet Kefir was identified as Lactobacillus plantarum, and the strain was shown to produce 90 mgL(-1) of EPS when grown in a semi-defined medium. The molecular mass of the EPS was 1.1 × 10(5)Da. The EPS was composed of glucose and galactose in a molar ratio of 2.71:1, with possible presence of(More)
Exopolysaccharide (EPS) produced by Streptococcus thermophilus GST-6 in skim milk was extracted and purified. The EPS was composed of glucose and galactose in a molar ratio of 1.80:1.03 with identical primary structure to the EPS from S. thermophilus ST1 reported previously. The purified EPS was sulphated at a sulphonation degree of 0.26±0.03, and presence(More)
The exopolysaccharide (EPS) produced by Lactobacillus plantarum YW32 was purified and characterized, and the in vitro bioactivities of the purified EPS were also evaluated. The EPS had a molecular weight of 1.03×10(5) Da, and it consisted of mannose, fructose, galactose and glucose in an approximate molar ratio of 8.2:1:4.1:4.2. Microstructural studies of(More)
Tim-3 (T cell immunoglobulin and mucin domain 3), belonging to the member of the novel Tim family, has been confirmed that it plays a critical negative role in regulating the immune responses against viral infection and carcinoma. Recently, it has also been reported that the over-expression of Tim-3 is associated with poor prognosis in solid tumors.(More)
Hypercoagulable state and disorganized angiogenesis are two conspicuous characteristics during tumor progression. There are a considerable number of clinical trials focusing on the effects of anticoagulant and antiangiogenic drugs on the survival of cancer patients. Favorable outcomes have been observed. Excessive blood coagulation not only causes(More)
OBJECTIVE To investigate the relationship between (GT)n polymorphism and esophageal cancer by analyzing the connection between microsatellite polymorphisms in the promoter of heme oxygenase-1 and the clinicopathological characteristics of esophageal squamous cell carcinoma (ESCC) in Han chinese population. METHODS The (GT)n repeats in HO-1 gene in 83 male(More)
In the title compound, Bi(2)B(8)O(15), the Bi atom is coordinated to five or six O atoms. The B atoms exhibit two kinds of hybridization, sp(2) and sp(3), seen in the BO(3) triangles and BO(4) tetrahedra, respectively. Three BO(3) triangles are connected to form a B(3)O(6) planar ring. All atoms in the structure are connected together to form an infinite(More)
Adaptive voltage scaling (AVS) regulator is proposed in the paper. Based on hybrid pseudo type-III (HPT3) compensator, the digital load is powered adaptively with operation frequency. Consequently, the power dissipation of digital circuit is reduced significantly, especially for lower operation frequency. The proposed HPT3 compensator consists of analog(More)
The structure of rubidium gadolinium bis(tungstate), RbGd(WO4)2, has been determined. The crystal is built up from corner- and edge-sharing WO6 octahedral and GdO8 polyhedral groups, giving rise to a Gd-WO4 polyhedral backbone surrounding structural cavities filled with Rb+ cations. The Gd and Rb atoms lie on twofold axes.
