In order to improve the availability of phytase and probiotics together, a phytase gene from Aspergillus ficuum has been expressed in Lactobacillus. In this study, the transformed Lactobacillus with phytase gene was fed to pigs to determine its effect on pig production, feed conversion and gut microbes. Forty eight, 60-day-old, castrated pigs (Duroc${\times}$Landrace${\times}$Pietrain) were assigned to 6 groups, 8 pigs for each group. Group 1 was the control, group 2 was added with chlortetracycline (500 mg/kg), group 3 was added with the transformed Lactobacillus (500 mg/kg) with 20% (w/w) of calcium monohydrogen phosphate (CMP, $CaHPO_{4}$) removed, group 4 was added with the natural Lactobacillus (500 mg/kg) with 20% (w/w) of CMP removed, group 5 was added with the transformed Lactobacillus (500 mg/kg) with 40% (w/w) of CMP removed, group 6 was added with phytase (500 mg/kg) with 40% (w/w) of CMP removed. The results showed: i) the average daily gain (ADG) was improved in groups 2, 3 and 4 (p<0.05); ii) the diarrhea rates in the groups added with Lactobacillus were lower than in the other groups (p<0.05), in which the transformed Lactobacillus had more effect on reducing digestive disease; iii) the transformed Lactobacillus was most effective in improving the digestibilities of crude protein (CP), calcium (Ca), phosphorus (P), compared with the other groups (p<0.05); iv) Lactobacillus could increase lactic acid bacterium number and ammonia concentrations, and decrease pH values and E. coli number in pig feces (p<0.05); v) the phytase activity in the feces of pigs fed with the transformed Lactobacillus was 133.32 U/g, which was higher than in group 4 (9.58 U/g, p<0.05), and was almost the same as group 6 (135.94 U/g); vi) the transformed Lactobacillus could increase serum concentrations of IgA, triglyceride, and glutamic oxaloacetic transaminase activity (p<0.05), and had no significant effect on other serum indexes (p>0.05).

Hu sheep was sampled randomly from Huzhou city, Zhejiang province, China. Of the 11 genetic markers from the blood examined by starch-gel and cellulose acetate electrophoresis, polymorphisms in Hu sheep were found for 10 loci, i.e. post-albumin (Po), transferring (Tf), alkaline phosphatase (Alp), leucine aminopeptidase (Lap), arylesterase (Ary-Es), hemoglobin-$\beta$ (Hb-$\beta$)、Xprotein(X-p), carbonic anhydrase (CA), catalase (Cat) and lysine (Ly). The same data except for Po locus were collected from another 14 sheep breeds from China and other countries, in order to ascertain their genetic relationships with one another and with the Hu sheep. The sheep populations from the east and south of Central Asia can be classified into three genetic groups: 'Mongolian sheep', 'South Asian sheep' and 'European sheep'. The Hu sheep belong to the 'Mongolian sheep' group.

<P><B>Abstract</B></P><P>Charcot‐Marie‐Tooth disease (CMT) is the most common inherited peripheral neuropathy. Mutations in the pyruvate dehydrogenase kinase isoenzyme 3 (<I>PDK3</I>) gene have been found to cause X‐linked dominant CMT type 6 (CMTX6). This study identified the p.R158H <I>PDK3</I> mutation after screening 67 probable X‐linked CMT families. The mutation fully segregated with the phenotype, and genotyping the family indicated the mutation arose on a different haplotype compared with the original Australian CMTX6 family. Results of bisulphite sequencing suggest that methylated deamination of a CpG dinucleotide may cause the recurrent p.R158H mutation. The frequency of the p.R158H <I>PDK3</I> mutation in Koreans is very rare. Magnetic resonance imaging revealed fatty infiltration involving distal muscles in the lower extremities. In addition, fatty infiltrations were predominantly observed in the soleus muscles, with a lesser extent in tibialis anterior muscles. This differs from demyelinating CMT1A patients and is similar to axonal CMT2A patients. The clinical, neuroimaging, and electrophysiological findings from a second CMTX6 family with the p.R158H <I>PDK3</I> mutation were similar to the axonal neuropathy reported in the Australian family.</P>

High-energy synchrotron X-ray diffraction technique was used to in-situ characterize microstructure, lattice strain, and phase transition behavior of a Ni<SUB>47</SUB>Ti<SUB>44</SUB>Nb<SUB>9</SUB> shape memory alloy. Phase transformation kinetics and deformation mechanisms were studied under a uniaxial tension at three testing temperatures, i.e., -70<SUP>o</SUP>C, 25<SUP>o</SUP>C, and 150<SUP>o</SUP>C. At a testing temperature of -70<SUP>o</SUP>C, a complicated phase transformation with four stages of micromechanical deformation was identified which is associated with changes of martensite substructures. At room temperature of 25<SUP>o</SUP>C, there was no stress-induced selection process of variants of B19' phases observed. Whereas at a testing temperature of 150<SUP>o</SUP>C, there was no any phase transformation observed. It is verified that β-Nb phase, an effective stabilizer for the austenite, delays the process of martensitic transformation and relaxes the strain energy without strengthening the matrix. This new finding is important to understand the relationship between the micromechanical deformation behavior and phase transformations in the Ni<SUB>47</SUB>Ti<SUB>44</SUB>Nb<SUB>9</SUB> SMA.

<P><B>Abstract</B></P><P>Mutations in the gap junction protein beta 1 gene (<I>GJB1</I>) cause X‐linked Charcot‐Marie‐Tooth disease type 1 (CMTX1). CMTX1 is representative of the intermediate type of CMT, having both demyelinating and axonal neuropathic features. We analyzed the clinical and genetic characterization of 128 patients with CMTX1 from 63 unrelated families. Genetic analysis revealed a total of 43 mutations including 6 novel mutations. Ten mutations were found from two or more unrelated families. p.V95M was most frequently observed. The frequency of CMTX1 was 9.6% of total Korean CMT family and was 14.8% when calculated within genetically identified cases. Among 67 male and 61 female patients, 22 females were asymptomatic. A high‐arched foot, ataxia, and tremor were observed in 87%, 41%, and 35% of the patients, respectively. In the male patients, functional disability scale, CMT neuropathy score, and compound muscle action potential of the median/ulnar nerves were more severely affected than in the female patients. This study provides a comprehensive summary of the clinical features and spectrum of GJB1 gene mutations in Korean CMTX1 patients.</P>

Zhao, X.,Lee, J.Y.,Kim, C.-R.,Heo, J.,Shin, C.M.,Leem, J.-Y.,Ryu, H.,Chang, J.-H.,Lee, H.C.,Jung, W.-G.,Son, C.-S.,Shin, B.C.,Lee, W.-J.,Tan, S.T.,Zhao, J.,Sun, X. North-Holland 2009 Physica E, Low-dimensional systems & nanostructure Vol.41 No.8
This study evaluated the effects of precursor concentration ranging from 0.06 to 1.5M on the properties of hydrothermally grown ZnO on annealed ZnO buffered Si substrates. At relatively low concentrations (no more than 0.5M), well-aligned ZnO arrays were grown on ZnO/Si(100) due to heterogeneous nucleation. As the concentration was increased to 1.0M, the morphologies changed to randomly accumulated particles as a result of homogeneous nucleation. The crystal and optical properties of the materials were investigated by X-ray diffractometer (XRD) and photoluminescence (PL) measurement, respectively. It was found that the best crystal and optical properties were obtained with concentrations of 0.5 and 0.3M, respectively. These properties were observed to degrade when the concentration was raised to more than 1.0M.

<P><B>Summary</B></P><P>The aim of this study is to investigate the clinical significance of the ratio between interleukin‐17 (IL‐17) secreting cell and FOXP3‐positive regulatory T cell (FOXP3<SUP>+</SUP> Treg) infiltration in renal allograft tissues with acute T‐cell‐mediated rejection (ATCMR). Fifty‐six patients with biopsy‐proven ATCMR were included. Infiltration of FOXP3<SUP>+</SUP> Treg and IL‐17‐secreting cells was evaluated with immunostaining for FOXP3 or IL‐17 on the biopsy specimens, and the patients were divided into the FOXP3 high group (Log FOXP3/IL‐17 > 0·45) or the IL‐17 high group (Log FOXP3/IL‐17 < 0·45). We compared the allograft function, severity of tissue injury, and clinical outcome between the two groups. In the IL‐17 high group, allograft function was significantly decreased compared with the FOXP3 high group (<I>P </I><<I> </I>0·05). The severity of interstitial and tubular injury in the IL‐17 high group was higher than the FOXP3 high group (<I>P </I><<I> </I>0·05). The proportions of steroid‐resistant rejection, incomplete recovery and recurrent ATCMR were higher in the IL‐17 high group than in the FOXP3 high group (all indicators, <I>P </I><<I> </I>0·05). The IL‐17 high group showed lower 1‐year (54% versus 90%, <I>P </I><<I> </I>0·05) and 5‐year (38% versus 85%, <I>P </I><<I> </I>0·05) allograft survival rates compared with the FOXP3 high group. Multivariate analysis revealed that the FOXP3/IL‐17 ratio was a significant predictor for allograft outcome. The FOXP3/IL‐17 ratio is a useful indicator for representing the severity of tissue injury, allograft dysfunction and for predicting the clinical outcome of ATCMR.</P>

A WO_3/TiO_2 composite film was in-situ prepared in tungstate electrolyte and characterized by Electron microscopy, X-ray diffraction, UV―Vis spectrophotometer and Photoluminescence. The oxide film consists of mixture phases of anatase and rutile, showing porous structures and metallurgical bond with substrate. With the incorporation of WO_3 into TiO_2, the optical absorption edge of TiO_2 filmwas shifted to longer wavelength slightly and the separation between electrons and holes was promoted effectively. WO_3/TiO_2 composite film with increased photo quantum efficiency will be promising in the treatment of environmental pollutants.
