This study investigated the quality characteristics of cookies containing mugwort powder, which is well known for its various functions and biological activity. Cookie samples were made by adding the mugwort powder at different levels of 0%, 1%, 3% and 5%. In this study, moisture, pH, color, spread factor, hardness, antioxidant activity and sensory evaluation of cookies were examined. The pH and moisture were increased when increasing levels of mugwort powder were used. The L, a and b color values were significantly (p<0.001) decreased when increasing levels of mugwort powder were used. The spread factor of the cookies was significantly (p<0.01) decreased when increasing levels of mugwort powder were used.. The hardness and DPPH radical scavenging activity of cookies were significantly (p<0.001) increased when increasing levels of mugwort powder were used. Cookies containing 3% of mugwort powder showed the highest taste and texture scores. The scores for Flavor and color decreased when more mugwort powder was added.
Food deprivation decreases hepatic glutathione (GSH) levels, which is ascribed to alterations in availability of hepatic cysteine, a rate limiting factor for the GSH synthesis. The present study examines the effects of food deprivation on hepatic metabolism of sulfur amino acid in male rats. In rats fasted for 24 or 48 hours, hepatic GSH levels were decreased from $6.70{\pm}0.16{\mu}mol/g$ liver to $4.02{\pm}0.20$ or $4.06{\pm}0.07{\mu}mol/g$ liver, respectively. Hepatic S-adenosylmethionine levels were also decreased in fasted rats, but S-adenosylhomocysteine levels were increased. Hepatic methionine levels were not changed by food deprivation for 48 hours. On the other hand, hepatic cysteine or taurine levels were increased from $106.2{\pm}4.1$ to $130.0{\pm}2.7$ nmol/g liver or from $2.45{\pm}0.43$ to $5.07{\pm}0.78{\mu}mol/g$ liver, respectively, in 48-hour fasted rats. Activity of cystathionine beta-synthase catalyzed homocysteine to cystathionine, was markedly decreased, but activity of betaine homocysteine methyltransferase was increased in fasted rats, indicating that methylation of homocysteine to methionine is activated. Also activity of cysteine dioxygenase, involved in taurine synthesis, was increased. These results suggested that hepatic methionine levels were maintained in rats fasted for 48 hours through increase in homocysteine methylation, and hepatic GSH may serve as a cysteine supplier reservoir in fasting state.
An experiment was conducted to examine the effect of different feeding levels of concentrate (85, 100 and 115%) and age (15, 18 and 24 month) on fatty acid synthetase (FAS) activities in the 4 locations of adipose tissues (intermuscular, ITER; intramuscular, ITRA; kidney, KIDN and subcutaneous, SUBC) of 36 Korean native cattle (Hanwoo) steers. Steers of 100% feeding group were fed the amount of concentrate to meet the daily nutrient requirements, and the steers of second and third groups were fed concentrates at the levels of 85% and 115% of that of control group, respectively, up to 18 month of age. Thereafter, the steers were fed ad libitum up to 24 month of age. Feeding level of concentrates tended to affect the FAS activity of various adipose tissues in Hanwoo steers of each age. The FAS activity of ITER adipose tissue had the decreasing trend as the age of steers advanced while those of ITRA and SUBC adipose tissues had the slightly increasing tendency with age. The FAS activity based on the pooled data increased with the feeding level of concentrates (115%) in which the activities from all 4 adipose depots were higher than those with the lowest (85%) feeding level. Similar trend was observed from the pooled data of feeding level of concentrates by age of steers in which the FAS activities for all 3 ages were increased with feeding levels of concentrates. But the response in the FAS activity to the feeding level varied with age.

Objectives: The purpose of this study was to analyze the association between health status and physical activity levels in older adults (over 65 years) in Korea. Methods: The participants were selected from the database of the Seventh Korea National Health and Nutrition Examination Survey (KNHANES VII), conducted by the Korea Centers for Disease Control and Prevention in 2017. A chi-square test and logistic regression analysis were used to analyze data. Results: The findings showed that health conditions such as hypertension and diabetes were related to physical activity levels of the older adults. In addition to health status, social and economic factors such as gender, age, and geographic region should be considered in order to initiate the practice of aerobic and strength exercise in the older adults. Conclusions: To initiate physical activity levels in the older adults, it is necessary to consider support for costs involved, policies required for the development of integrated exercise programs, expansion of public exercise facilities, and improved facilities.
To investigate the effects of internal radiation of various intensityon the test crop(flax), seeds of four levels of activity($15.5{\times}10-4 $\mu$c/grain, 9.0{\times}10-2$\mu$c/grain, 2.2{\times}100$\mu$c/grain and 3.8{\times}10-1$\mu$c/grain)$ which had been obtained by immersing them into various concentrations of P-32 original solution (total activity: 90 mc, To: 3/21) for 24 hours at room temperature, were germinated, transplanted later into pots, and the rate of germination and the successive growth were observed, and the inorganic conents of the plant top were analyzed. The results are as follows: 1. At the early stage of germination, the plants manifested themselves both inhibitory and promotive effects at higher and lower activity levels respectively, compared those of the control. These difference of growth on account of different levels of activity appeared, however, to be gradually narrowed in the course of time after germination, except at the highest activity. 2. Two weeks after transplanting, the plants of the lowest activity showed more vigorous growth than those of control. The plants belonging to the other activity levels on the other hand, tended to be less growing, the higher the activity. However, this growth gap between treatments seemed to be progressively closed one month after transplanting. 3. Most of the leaves and stems of the plants belonging to the highest activity level ($3.8{\times}101$\mu$c/grain$) were withered during the early stage of growth, and this damage did not recover. 4. Practically no difference of growth was observed among treatments(excluding that of highest activity) one and half months after transplanting. 5. The fluorescence tended to be mroe delayed than the control, as the activity decreased. 6. There was a tendency that the number of pods harvested were larger in the plants treated with P-32 than that of the control. 7. The proportion of fiber in the plants at harvest appeared to be larger at lower activity and smaller at higher P-32 concentration than that of control. 8. As for the inorganic contents of the plant top harvested the floowing tendency was observed: (1) Nitrogen content was highest at the highest activity level at which the poorest growth ensued. (2) There was no clear difference of phosphorus content among treatments. (3) The contents of potassium and magnesium were higher than control at the medium levels of activity. (4) Calcium content of all treated blocks was found to be more than that of control.
Previously, we found that KTH-13 isolated from the butanol fraction of Cordyceps bassiana (Cb-BF) displayed anti-cancer activity. To improve its antiproliferative activity and production yield, we employed a total synthetic approach and derivatized KTH-13 to obtain chemical analogs. In this study, one KTH-13 derivative, 4-(tert-butyl)-2,6-bis(1-phenylethyl)phenol (KTH-13-t-Bu), was selected to test its anti-cancer activity. KTH-13-t-Bu diminished the proliferation of C6 glioma, MDA-MB-231, LoVo, and HCT-15 cells. KTH-13-t-Bu induced morphological changes in C6 glioma cells in a dose-dependent manner. KTH-13-t-Bu also increased the level of early apoptotic cells stained with annexin V-FITC. Furthermore, KTH-13-t-Bu increased the levels of cleaved caspase-3 and -9. In contrast, KTH-13-t-Bu upregulated the levels of pro- and cleaved forms of caspase-3, -8, and -9 and Bcl- 2. Phospho-STAT3, phospho-Src, and phospho-AKT levels were also diminished by KTH13-t-Bu treatment. Therefore, these results strongly suggest that KTH-13-t-Bu can be considered a novel anti-cancer drug displaying pro-apoptotic activity.

Water extract from Prunella vulgaris L. (PVW) was tested for colon cancer chemopreventive activity by measuring the activities of cytochrome P450 1A1, phase Ⅱ detoxification enzyme [quinone reductase (QR) and glutathione S-transferase (GST)] and ornithine decarboxylase (ODC) and glutathione (GSH) levels in cultured human colorectal adenocarcinoma HT-29 cells. PVW significantly inhibited 7,12-dimethylbenz[a]anthracene (DMBA)-induced cytochrome P450 1A1 activity at 10 and 50 ${\mu}g/ml$. PVW induced QR activity in a dose-dependent manner over a concentration range of $1{\sim}50\;{\mu}g/ml$. GST activity was also induced with the treatment of PVW in HT-29 cells. In addition GSH levels were increased with PVW. PVW inhibited ODC activity, a key enzyme of polyamine biosynthesis, which is enhanced in tumor promotion. These results suggest that Prunella vulgaris L. has colon cancer chemopreventive activity by inhibiting cytochrome P450 1A1 and ODC activities and by increasing phase Ⅱ enzyme activity and GSH levels.
The effect of IAA on lysine decarboxylase(LDC)activity, diamine oxidase (DAO) activity and the polyamine level in seedlings of soybean were investigated. The seedlings of soybean were treated with IAA (10-8M, 10-6M, 10-4M) and LDC activity, DAO activity and polyamine levels of cotyledon, elongating hypocotyl, elongated hypocotyl and the root were measured after 4, 6, 8, 10 days. Increased concentration of IAA stimulated the LDC activity and increased the level of polyamine in the seedlings, which reducing the DAO activity and polyamine level was increased in the seedlings. The light also stimulated the IAA effect on polyamine level and DAO activity, and polyamine level was higher in the seedlings grown in the light than those in the dark. Cadaverine was the most abundant polyamine in the seedlings of soybean. The levels of diamines, cadaverine, putrescine were higher in the elongated hypocotyl and root than in the elongating hypocotyl, but the levels of spermidine and spermine were relatively higher in the cotyledon than in the other parts. Accumulation of diamines by high concentration of IAA is postulated to be a phenomenon of inhibition in seedlings growth.
This study examined the physical activity and dietary patterns of university students in Nairobi County and compared to their weight status. The study was a cross-sectional analytical design with a sample of 260 undergraduate students randomly selected from two private and two public universities. A semi-structured questionnaire was used to gather information from students. Students weight and height measurements were also obtained. Data was analyzed using SPSS version 22. The study results showed that 53.5% of the students met the recommended levels of moderate physical activity and 18.8% of the students met the recommended levels of vigorous physical activity. Majority of the students consumed fast foods sweetened beverages and pastries most times in a week. The study also showed that 31.2% of the students were overweight and 6.2% were obese. The study reveals that most students did not achieve the recommended levels of vigorous physical activity and showed some poor dietary patterns. Findings show clear evidence of high prevalence of overweight among university students but focus should be on fitness rather than fatness. Efforts should be made to promote physical activity participation and good dietary practices within university environments.
This study examined the α-glucosidase inhibitory, and apoptosis- and anti-muscular-related factors of goat meat extracts from forelegs, hind legs, loin, and ribs. The goat meat extracts were evaluated for their α-glucosidase inhibitory activity. The gene and protein expression levels of Bcl-2-associated X (bax), p53, and p21 were examined by reverse transcription polymerase chain reaction (RT-PCR) and immunoblotting in AGS and HT-29 cells. The expression levels of Atrogin-1 and MHC1b were examined by RT-PCR in C2C12 myoblasts, and the expression levels of Atrogin-1, muscle atrophy F-box (MAFbx), muscle RING-finger protein-1 (MuRF-1), and myosin heavy chain-7 were investigated by immunoblotting. α-Glucosidase inhibitory activity was higher in ethanol extract than in hydrous and hot water extracts. BAX and p53 expression levels were higher (p<0.05) in AGS cells treated with goat meat extract than those of cells treated with no goat meat extract. In HT-29 cells, the protein expression levels of BAX, p53, and p21 were higher (p<0.05) in the cells treated with goat meat extract than those of cells not treated with goat meat extract. In dexamethasone-treated C2C12 cells, goat meat extract treatment lower (p<0.05) the expression of Atrogin-1 and lower (p<0.05) the expression of MAFbx and MuRF-1. The results of the present study indicate that goat meat extracts have α-glucosidase inhibitory activity in vitro. In addition, apoptosis was induced in AGS cells and HT-29 cells treated with goat meat extract, and anti-muscular atrophy activity was also observed in C2C12 cells treated with goat meat extract.
