The purpose of this study is to evaluate the effect of $HTR^{TM}$ (hard tissue replacement, Bioplant Inc, U.S.A) polymer on short-term healing as a grafting material for alveolar ridge augmentation. A 48-year-old female presented insufficient bone height and width for the placement of implants. $HTR^{TM}$ polymer was used for ridge augmentation. Bone biopsy was harvested 8 months after the ridge augmentation procedure. $HTR^{TM}$ polymer displayed rapid bone regeneration and mature lamellar and trabecular bone redevelopment. Clinical and histologic observation from the treatment of the patient presented suggest that $HTR^{TM}$ polymer seems to be a appropriate material for alveolar ridge augmentation.

$MnBi_{1-x}Ti_x$ (x = 0, 0.4, 0.7, 1) alloys were prepared by arc-melting, followed by heat treatment. X-ray diffraction (XRD) and vibrating sample magnetometer (VSM) were used to measure and investigate the phase structure and magnetic properties. The temperature dependent magnetization curves indicate that the phase transitions between LTP and HTP MnBi occur with heating or cooling in $MnBi_{1-x}Ti_x$ ($x{\leq}0.7$) samples. However, MnTi samples are in $Mn_2Ti$ single-phase, with very low magnetic properties. Furthermore, the coercivity exhibits a positive temperature coefficient. The results show that the optimal content of Ti for the coercivity of $MnBi_{1-x}Ti_x$ alloy is x = 0.4. For MnBi sample, the coercivity reaches a maximum value of 1.13 T at 550 K. However, the remanence and energy product show apparent decrease with the addition of Ti in $MnBi_{1-x}Ti_x$ alloys.

Cerebral monoamines play important roles as neurotransmitters that are associated with various stressful stimuli. Some components such as ginsenosides (triterpenoidal glycosides derived from the Ginseng Radix) may interact with monoamine systems. The aim of this study was to determine whether ginsenoside Rb1 can modulate levels of the monoamines such as dihydroxyphenylalanine (DOPA), dopamine (DA), norepinephrine (NE), epinephrine (EP), 3,4-dihydroxyphenylacetic acid (DOPAC), 5-hydorxytryptamine (5-HT), 5-hydroxindole-3-acetic acid (5-HIAA), and 5-hydroxytryptophan (5-HTP) in mice frontal cortex and cerebellum in response to immobilization stress. Mice were treated with ginsenoside Rb1 (10 mg/kg, oral) before a single 30 min immobilization stress. Acute immobilization stress resulted in elevation of monoamine levels in frontal cortex and cerebellum. Pretreatment with ginsenoside Rb1 attenuated the stress-induced changes in the levels of monoamines in each region. The present findings showed the anti-stress potential of ginsenoside Rb1 in relation to regulation effects on the cerebral monoaminergic systems. Therefore, the ginsenoside Rb1 may be a useful candidate for treating several brain symptoms related with stress.

Streptomyces sp. AD001 is a Gram-positive soil actinomycetes secreting an uncharacterized 2,4-dichlorophenol (DCP) oxidizing enzyme, whose activity is similar to the previously known Actinomycetes lignin-peroxidase (ALiP). This extracellular peroxidase was purified from Streptomyces sp. AD001 as a single protein band on an SDS-PACE by ammonium sulfate fractionation, Q-sepharose, concanavalin A, and Bio-Gel HTP column chromatographies. The molecular mass of the purified peroxidase was determined by SDS-PAGE to be 45.2 kDa, and 49.7 kDa with MALDI-TOF-MS, respectively. The highest level of peroxidase activity was observed at pH 7.5 and $30^{\circ}C$. The amino terminal sequence of the purified peroxidase (G-E-P-E-E-G-N-V-D-G-T-L) showed no significant homologies to my known proteins, suggesting that Streptomyces sp. AD001 may secrete a novel kind of bacterial peroxidase Initial rate kinetic data of the 2,4-DCP oxidation were best modeled with a random-binding bireactant system.

Paenibacillus polymyxa E681 is known to be able to suppress plant diseases by producing antimicrobial compounds and to promote plant growth by producing phytohormones, and secreting diverse degrading enzymes. In spite of these capabilities, little is known regarding the flow of information from the bacterial strain to the barley roots. In an attempt to determine the flow of information from the bacterial strain to barley roots, the strain was grown in the presence and absence of barley, and two-dimensional polyacrylamide gel electrophoresis (2D-PAGE) and MALDI-TOF mass spectrometry were used. 2D-PAGE detected approximately 1,000 spots in the cell and 1,100 spots in the supernatant at a pH 4-10 gradient. Interestingly, about 80 spots from each sample showed quantitative variations. Fifty-three spots from these were analyzed by MALDI-TOF mass spectrometry and 28 proteins were identified. Most of the cytosolic proteins expressed at higher levels were found in P. polymyxa E681 cells grown in the presence of barley rather than in the absence of barley. Proteins detected at a lower level in the surpernatant of P. polymyxa E68l cells grown in the presence of barley were lipoprotein, glucose-6-phosphate 1-dehydrogenase, heat-shock protein HtpG, spermidine synthase, OrfZ, ribonuclease PH, and coenzyme PQQ synthesis protein, and flagellar hook-associated protein 2 whereas proteins detected at a higher level in the surpernatant of P. polymyxa E681 cells grown in the presence of barley included D-alanyl-D-alanine ligase A, isopentenyl-diphosphate delta-isomerase, ABC transporter ATP-binding protein Uup, lipase. Many of the proteins belonging to plant-induced stimulons are associated with biosynthetic metabolism and metabolites of proteins and transport. Some of these proteins would be expected to be induced by environmental changes resulting from the accumulation of plant-secreted substances.

Purpose: The purpose of this study is to examine the effects of clinical art therapy programs utilized at schools on adolescents' suicidal thoughts and stress relief and to validate their effectiveness as a type of adolescent suicide prevention program. Methods: 12 sessions of clinical art therapy for youth suicide prevention were provided, once a week for 90 minutes, for 20 students at five middle schools in Seoul who were at high risk of committing suicide. By using the paired sample t-test, the study presented qualitative data on the analysis of pre- and post- questionnaires and on the subjects' EEG test and saliva test. Results: First, through the clinical art therapy program, the subjects' happiness index improved significantly while their scores of depression and suicidal ideation (suicidal thoughts) decreased. Second, in the EEG and saliva test conducted after the art therapy sessions, emotional stability increased and stress was reduced significantly. Third, according to the results of pre- and post- K-HTP tests and individual activities, the subjects started to recognize the seriousness of suicide and show emotional stability and positive changes in overall attitudes, valuing the rights and life of their own 'precious selves' (self respect). Conclusion: The results of this study indicate that the clinical art therapy program is significantly effective at preventing suicidal ideation by reducing suicidal impulses and depression, by increasing the happiness index, which can serve as a protective factor against suicide, and by increasing emotional stability while reducing stress. Based on the results, there is a need to develop policy measures regarding art therapy programs which can be utilized at schools.
