α-Amylase from Anoxybacillus thermarum A4 was purified using ammonium sulphate precipitation and Sephadex G-100 gel filtration chromatography, with 29.8-fold purification and 74.6% yield. A4 amylase showed best performance for soluble potato starch hydrolysis at 70 °C and pH 5.5-10.5. A4 amylase was extremely stable at +4 °C, and the enzyme retained over 65% of its original α-amylase activity a...

BACKGROUND A subset of thyroid tumors characterized by a follicular growth pattern can represent a serious diagnosis. Immunohistochemistry and molecular pathology for genetic profiling have been used in an attempt to resolve some of these issues. METHODS Tumor tissue samples of thyroid were obtained from 70 patients who underwent surgical therapy. They were divided into 4 groups: 20 adenomato...

BACKGROUND Both statins and thiazolidinediones have antiinflammatory properties. However, the exact mechanisms underlying these effects are unknown. We investigated whether atorvastatin (ATV) and pioglitazone (PIO) increase the myocardial content of lipoxin-A4 and 15(R)-epi-lipoxin-A4 (15-epi-LXA4), both arachidonic acid products with strong antiinflammatory properties. METHODS AND RESULTS In...

Study Design Survey of 100 worldwide spine surgeons. Objective To develop a spine injury score for the AOSpine Thoracolumbar Spine Injury Classification System. Methods Each respondent was asked to numerically grade the severity of each variable of the AOSpine Thoracolumbar Spine Injury Classification System. Using the results, as well as limited input from the AOSpine Trauma Knowledge Forum, t...

In a new simple application of the non-Abelian discrete symmetry A4 to chargedlepton and neutrino mass matrices, we show that for the current experimental central value of sin 2θ13 ≃ 0.1, leptonic CP violation is necessarily large, i.e. | tan δCP | > 1.3. The non-Abelian discrete symmetry A4 was introduced [1, 2, 3] to achieve the seemingly impossible, i.e. the existence of a lepton family symm...

Non-human primates (NHPs) are confirmed as reservoirs of Cryptosporidium spp., Giardia intestinalis, and Enterocytozoon bieneusi. In this study, 197 fresh fecal samples from 8 NHP species in Qinling Mountains, northwestern China, were collected and examined using multilocus sequence typing (MLST) method. The results showed that 35 (17.8%) samples were positive for tested parasites, including Cr...

OBJECTIVE The present study evaluated the subcutaneous connective tissue reactions and the radiopacity of MTA, Portland cement (PC), and Portland cement plus bismuth oxide (BO). STUDY DESIGN Forty rats were divided into 5 groups (n = 8 per group): A1: Control (empty capsule); A2: Pro-Root MTA; A3: PC; A4: PC + BO 1:1; and A5: PC + BO 2:1. Polyethylene tubes were filled with the test materials...

In this paper, we show that there does not exist a quadruple of positive integers a1 < a2 < a3 < a4 such that aiaj + 1 (i 6= j) are all members of the Tribonacci sequence (Tn)n≥0.

Quantification of the Nitrogen (N)-supplying capacity of organic manures provides an important insight into more effective N management practices. The aims of this study were to determine the potential N mineralization of cow manure (CM), poultry manure (PM), urea fertilizer (UF) and the combined use of cow manure + urea fertilizer (CM + UF) for silage maize (Zea mays L.) in a calcareous so...
