We tested performance of the 4C1 beamline for analyzing structures of proteins in solution using small angle X-ray scattering (SAXS) at the Pohang Light Source(PLS). Structurally well-known proteins such as lysozyme and $Bcl-XL(\vartriangle TM/\vartriangle loop)$ were used for the study. Low resolution solution structures of lysozyme and $Bcl-XL(\vartriangle TM/\vartriangle loop)$ were obtained at a resolution of at least i.2 nm, and the structures were basically same as those calculated from the crystal structures of the proteins. We also used $Bcl-XL(\vartriangle TM/\vartriangle loop)$ with a long flexible loop attached [$Bcl-XL(\vartriangleTM))$] and obtained significantly different data from $Bcl-XL(\vartriangle TM/\vartriangle loop)$, although the electron density map of the loop is known to be invisible from the crystal structure of $Bcl-XL(\vartriangleTM))$. We confirm that SAXS experiment is a powerful tool for the structural study of proteins in solution and the 4Cl beamline at the PLS is well-equipped and suitable for the protein solution SAXS experiment.

Purpose of study: To compare on bone formation between ovariectomized rats and normal rats after graft of alloplastic bone material. Material and methods: Twenty female rats were used in this study. They were divided into two groups by each ten rats. One group was ovariectomized and grafted alloplastic bone material. Other group was non-ovariectomized and grafted alloplastic bone material. After a healing time of 4 weeks, the animals were sacrificed and decalcified preparations were routinely processed for histologic evaluations. Results: Ovariectomy group was significantly lesser bone formation compared with non-ovariectomy group. Conclusions: Ovariectomy acts as a negative factor in new bone formation.

The thermostable pectinase gene TmPec isolated from Thermotoga maritima was introduced into the NdeI site of pRSET-B vector and expressed in its intact form in Escherichia coli BL21. The overexpressed intact form of pectinase (TmPecN protein) was partially purified by heat-denaturation procedure. TmPecN showed the highest activity between 85 and $95^{\circ}C$, and at approximately pH 6.5. Enzyme activity was stably maintained at temperatures below $85^{\circ}C$. In the presence of $Ca^{2+}$, pectinase activity of TmPecN increased to 128.4% of normal level. In contrast, $Ba^{2+}$, $Zn^{2+}$, and $Mn^{2+}$ strongly inhibited TmPecN activity. We conclude that the biochemical properties of the intact form of TmPecN are comparable to those of the recombinant protein TmPec reported previously.

Chitin synthases(UDP-N-acetyl-D-glucosamine: chitin 4-$\beta$-N-acetyl-D-glucosaminyl transferase, EC 2.4.1.16) catalyze the synthesis of chitin from UDP-N-acetyl-D-glucosamine. Two zymogenic type of chitin synthase gene(TmCHS1 and TmCHS2) were amplified and its nucleotide sequences were determined. By the amino acid comparison and UPGMA tree grouping, TmChs1 and TmChs2 were classified as class II and class IV chitin synthases respectively. The class II type TmChs1 was grouped with others of Agaricales ectomycorrhizal mushroom. Additionally the phylogenetic tree was well adapted to Hymenomycete previously classified by morphological and physiological characteristics.

$Ho^{3+}/Yb^{3+}/Tm^{3+}$ tri-doped $NaY_{1-x}(WO_4)_2$ phosphors with proper doping concentrations of $Ho^{3+}$, $Yb^{3+}$ and $Tm^{3+}$ ($x=Ho^{3+}+Yb^{3+}+Tm^{3+}$, $Ho^{3+}$=0.04, 0.03, 0.02, 0.01, $Yb^{3+}$=0.35, 0.40, 0.45, 0.50 and $Tm^{3+}$=0.01, 0.02, 0.03, 0.04) were successfully synthesized via the microwave sol-gel route, and their upconversion properties were investigated. Well-crystallized microcrystalline particles showed fine and homogeneous microcrystalline morphology with particle sizes of $1-2{\mu}m$. The optical properties were comparatively examined using photoluminescence emission and Raman spectroscopy. Under excitation at 980 nm, the doped particles exhibited white emissions based on blue, green and red emission bands, which correspond to the $^1G_4{\rightarrow}^3H_6$ transitions of $Tm^{3+}$ in the blue region, the $^5S_2/^5F_4{\rightarrow}^5I_8$ transitions of $Ho^{3+}$ in the green region, the $^5F_5{\rightarrow}^5I_8$ transitions of $Ho^{3+}$, and the $^1G_4{\rightarrow}^3F_4$ and $^3H_4{\rightarrow}^3H_6$ transitions of $Tm^{3+}$ in the red region. The pump power dependence of the upconversion emission intensity and the Commission Internationale de L'Eclairage chromaticity coordinates of the phosphors were evaluated in detail.

Purpose. To develop a hard gelatine capsule containing meloxicam (Yuhan Meloxam capsule$\^$TM/), in vitro dissolution characteristics and bioavailability in beagle dog were compared with commercial product (Mobic capsule$\^$TM/). Methods. Meloxicam capsule$\^$TM/ was prepared by powder filling method using meloxicam, lactose, magnesium stearate, and others. The release of Meloxicam capsule$\^$TM/ and Mobic capsule$\^$Tm/ were monitored by USP dissolution method under various dissolution donditions - dissolution medium (pH 1.2, 4.0, 6.8 and water).

The TAZ activator 2-butyl-5-methyl-6-(pyridine-3-yl)-3-[2'-(1H-tetrazole-5-yl)-biphenyl-4-ylmethyl]-3H-imidazo[4,5-b]pyridine] (TM-25659) inhibits adipocyte differentiation by interacting with peroxisome proliferator-activated receptor gamma. 1 TM-25659 was previously shown to decrease weight gain in a high fat (HF) diet-induced obesity (DIO) mouse model. However, the fundamental mechanisms underlying the effects of TM-25659 remain unknown. Therefore, we investigated the effects of TM-25659 on skeletal muscle functions in C2 myotubes and C57BL/6J mice. We studied the molecular mechanisms underlying the contribution of TM-25659 to palmitate (PA)-induced insulin resistance in C2 myotubes. TM-25659 improved PA-induced insulin resistance and inflammation in C2 myotubes. In addition, TM-25659 increased FGF21 mRNA expression, protein levels, and FGF21 secretion in C2 myotubes via activation of GCN2 pathways (GCN2-$phosphoelF2{\alpha}$-ATF4 and FGF21). This beneficial effect of TM-25659 was diminished by FGF21 siRNA. C57BL/6J mice were fed a HF diet for 30 weeks. The HF-diet group was randomly divided into two groups for the next 14 days: the HF-diet and HF-diet + TM-25659 groups. The HF diet + TM-25659-treated mice showed improvements in their fasting blood glucose levels, insulin sensitivity, insulin-stimulated Akt phosphorylation, and inflammation, but neither body weight nor food intake was affected. The HF diet + TM-25659-treated mice also exhibited increased expression of both FGF21 mRNA and protein. These data indicate that TM-25659 may be beneficial for treating insulin resistance by inducing FGF21 in models of PA-induced insulin resistance and HF diet-induced insulin resistance.

The purpose of this study was to evaluate the antibacterial properties of a sealant containing S-PRG filler compared to those of two contemporary commercial sealants to determine the inhibition of bacterial growth in broth culture and biofilm formation using the CDC Biofilm Reactor. The BeautiSealant containing S-PRG filler, the fluoride releasing Clinpro$^{TM}$ sealant, which are known to have higher antibacterial effects, and the non-fluoride releasing Concise$^{TM}$ sealant were selected for this study. A Streptococcus mutans culture in BHI broth without sealant served as a negative control in the planktonic growth inhibition test. As a result, bacterial growth was inhibited in all three sealant groups compared to that in the control. The Clinpro$^{TM}$ sealant showed a significantly reduced number of CFUs compared to those of the BeautiSealant and Concise$^{TM}$ sealants. However, no significant difference was detected between the BeautiSealant and Concise$^{TM}$ sealants. The Clinpro$^{TM}$ sealant significantly decreased biofilm formation compared to that by the BeautiSealant and Concise$^{TM}$ sealants. No significant difference was observed between the BeautiSealant and Concise$^{TM}$ sealants. In conclusion, the sealant containing S-PRG filler had a less potent anti-bacterial property and increased biofilm formation capacity compared to those of the fluoride releasing Clinpro$^{TM}$ sealant.
