  • Several studies have been done regarding carcass traits and growth in pigs. Recently, these have progressed to examine increases in economic traits, including meat quality and meat quantity, by using candidate genes. One of them is the pituitary-specific protein PIT-1, a member of the POU (Pit-Oct-Unc) family of transcription factors playing an important regulatory role in developmental processes. In addition, muscle development is known to be regulated in part by growth factors and cytokines locally produced. Therefore, studies were performed to analyze PIT-1 genotypes and serum cytokines (IGF-I, IGF-II, TGF-${\beta}1$, EGF, cortisol, DHEA-S, IL-2, and IL-6) in castrated male pigs for their possible involvement in the development of carcass traits. The genotypes of PIT-1 gene were analyzed by PCR-RFLP with MspI restriction enzyme. But, only CD and DD genotypes, not CC genotype, have been detected. Based on PIT-1 genotyping, a significant difference in EGF expression beween CD type (78.8 ng/ml) and DD type (46.0 ng/ml) was detected (p<0.05), whereas other cytokines did not show any statistical significance depending on PIT-1 genotypes. Collectively, these results suggest the possibility that EGF could affect the formation of carcass traits.

  • The condition of mining companies that exploit natural resources in their business processes underline this research to emphasize on social and environmental issues. After twelve years of government regulation on CSR practices, this study investigates the factors that influence mining companies in disclosing information about corporate social responsibility based on legitimacy, stakeholders, and agency theory. Thus, independent variables are foreign ownership, company size, leverage, and the board of commissioners. The dependent variable is the corporate social reporting disclosure that is measured using GRI indexing. For sampling, we have used thirty-four Indonesian mining companies listed in IDX during the 2014-2018. out of which only fifty-two companies meet the sample criteria. All data should pass the classical assumption test to get the best estimator. Multiple linear regression is used to test the hypothesis, and the results show that the model is good, and can explain 60% of the dependent variable. Based on F-test, all four variables affect CSR practices simultaneously. The findings of this study suggest that foreign ownership and firm size influences CSR disclosure in a positive direction. However, this study did not support the hypothesis that leverage negatively affects CSR disclosure and board size measures positively affect CSR disclosure.

  • Consumptive behavior is the behavior of consuming goods that are actually less or not needed (especially in relation to the response to the consumption of secondary goods, namely, goods that are not really needed). This study aims to determine the influence of factors such as lifestyle, financial literacy, and social demographics on the consumptive behavior. The population in this research is students of STIE Bank BPD Jawa Tengah who had taken entrepreneurship I and II courses, with a total of 230 students, while the sample is determined by using accidental sampling technique and using Slovin formula, which obtained 70 samples. Quantitative data are used, and data collection method in this study is questionnaire. The analytical tool in this study is the multiple regression analysis. Data is processed by using the SPSS program 21. The results showed that there were positive influence of lifestyle variable on student consumptive behavior; positive influence of financial literacy variable on student consumptive behavior; and positive influence of social demographics on student consumptive behavior. The most dominant variable influencing consumptive behavior is variable X3 (social demographics) with a regression coefficient value of 0.510, followed by variable X1 (lifestyle) and variable X2 (financial literacy).

  • ABA-type block copolymers composed of poly(L-leucine)(PLL) as the A component and poly(ethylene glycol)(PEG) as the B component were synthesized by ring-opening polymerization of L-leucine N-carboxyanhydride initiated by primary amino group located at both ends of PEG chain. A silver sulfadiazine(AgSD)-impregnated wound dressing of sponge-type was prepared by the lyophilization method. Morphological structure of this wound dressing obtained by scanning electron microscopy(SEM) was composed of a dense skin layer and a macroporous inner sponge layer. Equilibrium water content(EWC) of wound dressing was above 10%. It increased with an increased of PEO content in the block copolymer due to the hydrophilicity of PEO. AgSD release from AgSD- impregnated wound dressing in PBS buffer(pH=7.4) was dependent on PEG composition in the block copolymer. Therefore, EWC and release of AgSD can be control by PEG composition. Antibacterial capacity of AgSD-impregnated wound dressing was examined in agar plate against Pseudmonas aeruginosa and Stapplococus aruous. Cytotoxicity of the wound dressing was evaluated by studing mouse skin fibroblast(L929). From the behavior of antimicrobial releasing and the investigation of the suppression of bacterial proliferation, it was supposed that the wound dressing containing antibiotics could protect the wound surfaces from bacterial invasion to suppress the bacterial proliferation effectively. In cytotoxicity observation, cellular damage was reduced by the control led released of AgSD from the LEL sponge matrix of AgSD-medicated wound dressing. In vivo test, granulous tissue formation and wound contraction or the AgSD and DHEA impregnated wound dressing were aster than any other groups.

  • Purpose: Advanced techniques now make it possible to remove considerable amounts of subcutaneous adipose tissue more safely with minimum blood loss. However, few have analyzed the metabolic consequences of liposuction. The purpose of this study was to identify the early effects of the surgical removal of subcutaneous fat on metabolic changes in patients who have undergone liposuction. Methods: Nineteen patients were evaluated from June 2005 to December 2005. Preoperative body weight, serums levels of lipids, apolipoprotein A1, dehydroepiandrosterone(DHEA), uric acid, insulin, and glucose were evaluated. Insulin resistance was determined using the homeostasis model assessment of insulin resistance (HOMA-IR), which is based on fasting glucose and insulin concentrations. All of these data were remeasured in 1 and 4 weeks postoperatively. Tumescent fluid was infiltrated using the superwet technique. The liposuction device used was a $Liposlim^{(R)}$ power-assisted unit. Results: Average volumes of infiltrate and aspirate were 3,268mL and 2,892mL, respectively. Results in 1 week postoperatively demonstrated a significant difference in high-density lipoprotein(HDL) cholesterol, apolipoprotein A1, insulin, and HOMA-IR levels. However, all values were within normal limits and returned to baseline in 4 weeks postoperatively.Conclusion: This study provides little to support the presumed therapeutic effect of liposuction. And, it is unclear whether liposuction can prevent or be used to treat the metabolic complications of obesity. However, the results of the present study lead us to believe that liposuction is a metabolically safe procedure.

  • This study was carried out to investigate the effect of short-term thermal stress on the serum concentrations of cortisol and DHEAS in BALB / c male mice. Cortisol and DHEAS concentrations in serum were measured by radioimmunoassay(RIA). We found there were significantly increased in the cortisol levels in 30 min-stressed group(T30) compared with control group(p<0.01), and then declined without significance in 120 min-stressed group (T120) compared with T30. By contrast, DHEAS levels were decreased without significance in both T30 and T120 compared with control group. Though short-term thermal stress, the continuous decline of DHEAS levels were observed. These results show that short-term thermal stress affects the serum levels of cortisol and DHEAS in mice. Furthermore, we found that DHEAS is a stress-related hormone and will be able to utilize as a stress marker.

  • For the development of drugs for alzheimer,s disease, the study was done to review the oriental pathology, clinical data, recent trends for research and strategy for future study. The results were as follows: 1. The medical term Chi-dsi implying alzheimer,s disease was referred for the first time in a medical book, Hwatasheneubijeon written by Hwa-Ta and its differentiation and treatment were studied more in Ming or Ching dynasties. Chi-dai can be differentated as weak(虛) syndrome and Shi(實) syndrome. This can be caused by deficiencies of renal Yin, renal Yang, cardiac Yin and hepatic blood, while that by deficiencies of pathological fluid(痰飮) and clotted blood(瘀血). 2. Dementia can be roughly classified as alzheimer's disease and multi-infarct disease. Its causes were known to be cholinergic transmitter, C-peptide, amyloid-${\beta}$, apolipoprotein, APP(amyloid precursor protein), TGF, MMP-9 and free radical. 3. In Korea experimental studies were chiefly done for the elimataion of C-peptide, amyloid-${\beta}$, apolipoprotein, APP for alzheimer's disease, for the development of drug inhibiting degerative change following CVA and loss of memory and also administrative measure was done by support of government. 4. Drugs of dimentia developed so far were Chi-Dai dan, extracts from aloe, mushroom, green tea, Ganoderma and also folic acid, vitamin C, DHEA and silk amino acid were reported to be effective in dimenta. 5. Future strategic research had better be done on dementia-inducing factors such as acetylcholine, C-peptide, amyloid-${\beta}$, apolipoprotein, APP, TGF, MMP-9 and free radical, development of animal model for dimentia, clinical study, epidemiology, nursing and administrative studies and also consortium for dimentia research should be formed so that repeated investment be avoided.

  • Seven epoxy- and hydroxyandrostane derivatives ($DH-1{\sim}DH-7$) and nine epoxy- and hydroxycholestane derivatives ($CH-1{\sim}CH-9$) with unsaturation in ring A and ring B were synthesized from DHEA and cholesterol, respectively. The antinociceptive effects of all synthesized compounds were measured by hot plate method. Most of androstane derivatives except $1{\alpha},2{\alpha}$-epoxy-4,6-androstadiene-3,17-dione (DH-3), and CH-6, CH-7 and CH-9 exhibited antinociceptive effect. 1,4-Androstadiene-$3{\beta},17{\beta}$-diol (DH-5, 100 mg/kg, $35.8{\pm}7.39$), $6{\alpha},7{\alpha}$-epoxy-1,4-androstadiene-3,17-dione (DH-4, 100 mg/kg, $32.6{\pm}5.50$) and $5{\alpha},6{\alpha}$-epoxy-17-oxo-androstan-$3{\beta}$-ol (DH-1, 100 mg/kg, $32.5{\pm}2.98$) were more effective than morphine (10 mg/kg, $30.6{\pm}0.5$). The analgesic effects of androstane derivatives on acetic acid writhing in mice were lower than aspirin. The androstane derivatives were less effective than ibuprofen at inhibiting effects on the carrageenin induced paw oedema. 4,6-Cholestadien-$3{\beta}$-ol (CH-5), $1{\alpha},2{\alpha}$-epoxy-4,6-cholestadien-$3{\beta}$-ol (CH-7) and $7{\alpha}$-hydroxy4-cholesten-3-one (CH-9) showed the decrease of serum triglyceride and total cholesterol levels in poloxamer P-407 injected rat.
