The porcine PRKAG3 (RN) gene encodes the regulatory gamma subunit of adenosine monophosphate-activated protein kinase (AMPK), which is a good candidate gene affecting meat quality. In this study, the effects of two missense mutations A595G (Ile199Val) and G154A (Gly52Ser) in porcine PRKAG3 gene on meat quality traits were studied in M. Longissimus dorsi (LD), M. Semispinalis capitis (SC) and M. Biceps femoris (BF) from different populations of 326 pigs. The PRKAG3 alleles 199I, 199IV, 52S and 52G were identified with PCR-RFLPs and all genotypes - 199I/199I, 199I/199V, 199V/199V, 52S/52S, 52S/52G and 52G/52G - were found. The frequency of V allele was larger than that of I allele in all populations. I allele frequency was zero in Chinese Meishan pigs (population D) especially. G allele frequency was larger than that of S allele in all populations except Large White (population A). Both variations at the PRKAG3 locus significantly affected these meat quality traits. The pork meat quality has not previously been established in Meishan or crosses thereof. The results suggested that generally pH of LD, SC and BF was higher in Meishan pigs than that in other populations. Moreover, Meishan pigs showed higher water-holding capacity and intramuscular fat (IMF), lower water content and water loss percentage compared to other populations in terms of the two variations. The results present here supply new evidence that alleles V199I and G52S at the PRKAG3 locus affect pork meat quality and provide useful information on pork production.

Nonlinear optical properties of cadmium telluride semiconductor nanocrystals were investigated for optical power self-limiting application. The semiconductor nanocrystals were synthesized through colloidal methods. The nonlinear refraction and the nonlinear figure of merit of CdTe nanocrystals in toluene ($\sim$8 $\times$ 10$^{-5}$ mol/L) were estimated to be $\sim$ -1 $\times$ 10$^{-13}$ m$^2$/W and $\sim$200, respectively. The optical power limiting through CdTe nanoscale materials was mainly by the nonlinear refraction because of the high nonlinear FOM.

AlSBA-1 molecular sieves were synthesized successfully and used for the synthesis of coumarins through Pechmann condensation. The synthesized AlSBA-1 catalysts were characterized by XRD, BET, SEM, FTIR, TGA techniques. The synthesized materials possess large surface area with mesopores. Pechmann condensation of 3-methoxyphenol and ethyl acetoacetate was carried out under solvent free condition and 7-methoxy-4-methylcoumarin was the main product. The selectivity of the product was found to be 74.04%. Among the synthesized catalysts, AlSBA-1(2) showed high activity than others due to high density of acid sites. Hence, AlSBA-1 molecular sieves a better choice of catalyst for the synthesis of coumarins.

Copper-encapsulated heteropolyacid-impregnated mesoporous MCM-48 (Cu-HPA-MCM-48) with copper in a reduced state was synthesized, and the CO<SUB>2</SUB> adsorption capacity was monitored. The synthesized material was characterized by XRD, N<SUB>2</SUB> adsorption-desorption, FT-IR, DSC, CO<SUB>2</SUB>-TPD and XPS. The low angle X-ray diffraction pattern of the Cu-HPA-MCM-48 demonstrates the encapsulation of copper inside the pore by the disappearance of higher-order peaks. This result is further supported by the presence of Cu<SUB>2p</SUB><SUP>3</SUP> and W<SUB>4f</SUB> peaks in XPS. The CO<SUB>2</SUB> adsorption capacity of Cu-HPA-MCM-48 was 70mg/g at 25<SUP>o</SUP>C. The energy of desorption and the heat of the reaction (ΔHr) were 21.2kJ/mol and 490Btu/lb, respectively, as determined by CO<SUB>2</SUB>-TPD and DSC. As the ΔHr value of Cu-HPA-MCM-48 approaches the CO<SUB>2</SUB> benchmark value (580Btu/lb), the catalyst exhibited improved CO<SUB>2</SUB> capturing capacity.

<P>Novel silver nanoparticles-decorated chitosan (CS)-polyvinyl alcohol (PVA) composite electrospun nanofibers, loaded with sulfanilamide for enhanced wound healing have been developed. Herein, formic acid was used as a reducing agent to produce in situ colloidal silver nanoparticles (AgNPs) in the composite polymeric solution with the active agent sulfanilamide. The prepared electrospun fibers were characterized using scanning electron microscopy (SEM), transmission electron microscopy (TEM), X-ray diffraction, ultraviolet spectroscopy, and thermal gravimetric analysis (TG). Further, in vitro release, antimicrobial properties and in vivo wound healing activity were evaluated. The results revealed that the composite fibers displayed a synergistic antibacterial and wound healing activities. (C) 2016 The Korean Society of Industrial and Engineering Chemistry.

The gene expression of porcine adiponectin and stearoyl coenzyme A desaturase (SCD) was investigated in this study. The partial gene sequences for adiponectin and SCD were amplified by RT-PCR from subcutaneous adipose tissue and cloned by TA cloning techniques. Sequences of these genes were determined and found to be highly homologous to that of other species, suggesting similar function of these genes as in other species. The transcripts of these adipocyte-related genes in pig tissues were measured by Northern analysis. The transcripts for adiponectin and SCD were highly expressed in porcine subcutaneous adipose tissue; the transcripts for SCD were also barely detected in the liver, but the greatest concentrations were in the adipose tissue. In porcine stromalvascular cells (S/V cells) cultured in vitro, transcripts for adiponectin and SCD increased gradually during adipocyte differentiation. The level of adipocyte adiponectin mRNA was associated with late adipocyte differentiation, indicating the gene may not be involved in adipocyte differentiation but has great importance in porcine adipocyte functions. The SCD transcripts were not detectable until 2 d after induction of adipocyte differentiation. It was highly expressed in differentiating porcine adipocytes (2 to 10 d after the induction of adipocyte differentiation), indicating a significant role of SCD in adipocytes.
