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.

The reticulated carbon foam have been used for their excellent properties in terms of thermal management which is getting important in industrial field currently. In this study, we measure the mechanical properties of the reticulated carbon foam which is heat-treated at various temperature from the prepared low-density phenol foam. Simultaneously, we observe microstructures with high resolution transmission microscope and measure the residual oxygen content of carbon foams to figure out the relationship between the apparent change of properties such as weight loss and linear shrinkage during heat treatment. In conclusion, the carbon foam heat-treated at $1400^{\circ}C$ shows the highest strength, and the mechanical behavior is believed to be strongly related to the creation of nano-size graphite crystals from the amorphous carbon during heat treatment. On the other hand, it is turned out that the weight loss occurred at the temperature under $1400^{\circ}C$ comes from the elimination of oxygen in the form of $CO_2$ or CO, but no evidence is found on weight loss mechanism at the temperature above $1400^{\circ}C$.

Objectives This systematic review is to support the effectiveness of herbal medicine for the treatment of simple obesity in adults. Methods A total of 8 electronic databases were searched in English, Chinese and Korean. Standard methodologies for the systematic review were used to search, analyze and synthesize data based on NECA's guideline for undertaking systematic review and meta-analyses for intervention. Results After screening 1781 potential articles, we identified 13 randomized controlled trials (RCTs). We conducted a meta-analysis for the study using Bangpungtongsung-san and Taeeumjowi-tang to evaluate the effectiveness of herbal medicines on weight loss compared to placebo control. Both herbs showed positive effect in weight, body mass index and waist circumference. In an analysis comparing herbal effects considering constitutions showed that proper treatment can lower adverse events. Conclusions Our results provide evidence that herbal medicine can be an effective treatment for the obesity compare to placebo or to conventional medicine without serious adverse events. Further study is needed to evaluate effectiveness of herbal medicines considering personalized treatment and its safety.

Uhwangchungsimwon(UC) is widely used as a herbal medicine on various circulatory disorders in Korea. The objective of this investigation was to characterize the acute, subacute hepatotoxic potency of orally administered UC in rats. In the acute and short-term studies, male rats of 150~170g were gavaged with 0, 7.5 g/kg once daily for up to 1, 5, 10 consecutive days. No differences in body weight, serum enzyme activities, absolute and relative liver weight and histopathological examination on liver between control and UC-fed groups were found. In the subacute study, UC was administered orally to both sexes of rats for 30 days(0, 1.875, 3.75 or 7.5 g/kg/day). There were no-doserelated hepatotoxic signs of general symptoms, body weight gain, water consumption and serum biochemical analysis. Slight decreases of food consumption observed at 3.75 and 7.5 g/kg groups of both sexes were due to be full of UC fed. Gross necropsy and histopathology revealed no evidence of hepatotoxicity related to UC. Our data indicate that hepatotoxicity was not caused by administration of UC up to 7.5 g/kg/dayfor 30 days in rats.

This report was carried out toxicity test for the mosquito coil made of Ginseng leaf and the residue after extraction of Ginseng root. This results are as follows: In the first group, was not shown any special difference on the body weight, the motion and dissection. In the second group, was not shown any Special difference on the body weight, considerable difference on the motion and considerable loss of appetite besides very slight loss, but came cack soon again to normal state by change of air after a moment. In the third group, the body weight and appetite was depressed very slightly and the motion was shown very slightly difference, but came back soon again to normal state by chenge of air after a moment too. No one was died, and all the animal were the normal state on the reslt of dessection, Therefore, we have positive evidence that this mosquito coil powder is applied to animals without any toxicity.

Recently, there is an increasing nationwide concern in Korea that exposure to electric and magnetic fields in the home environment may not be safe in humans. To identify possible effects of horizontally polarized magnetic fields (MF) exposure on embryo-fetal development, timed-mated female Sprague-Dawley rats (24/group) received continuous exposure to 60 Hz MF at field strengths of 0 Gauss (sham control), 50mG,833 mG, or 5000 mG. Dams received MF of sham exposures for 22hr/day on gestation days 6 through 20. Experimentally generated MF were monitored continuously througout the study. There was no evidence of maternal toxicity of developmental toxicity in any MF-exposed groups. Mean maternal body weight, organ weights, and gross findings in groups exposed to MF did not differ from those in sham control. No significant differences in fetal deaths, fetal body weight, and placental weight were observed between MF-exposed groups and sham control. External, visceral, and skeletal examination of fetuses demonstrated no significant differences in the incidence of fetal malformations between MF-exposed and sham control groups. In conclusion, exposure of pregnant Sprague-Dawley rats to 60 Hz at MF strengths up to 5000 mG during gestation day 6-20 did not produce any biologically significant effect in either dams of fetuses.

A study was conducted to evaluate effects of alfalfa meal on growth performance and gastrointestinal tract development of growing layer ducks to provide evidence for application of alfalfa meal in the duck industry. Two hundred and fifty-six healthy Shaoxing 7-wk old growing layer ducks were selected and randomly allocated to 1 of 4 dietary treatments based on corn and soybean meal and containing 0, 3, 6, and 9% of alfalfa meal for 8 wks. Each treatment consisted of 4 replicates of 16 ducks each. Briefly, birds were raised in separate compartments, and each compartment consisted of three parts: indoor floor house, adjacent open area and a connecting water area. The results showed: i) Growing ducks fed alfalfa meal diet were not significantly different in average daily gain, feed intake and gain-to-feed ratio from those fed no alfalfa diet (p>0.05). ii) Alfalfa meal increased the ratio crop, gizzard to live weight, caecum to live weight, the caecum index of growing ducks (p<0.05). iii) Villus height in duodenum and jejunum of growing ducks increased significantly with the increase of alfalfa meal levels (p<0.05). Crypt depth in duodenum and jejunum of growing ducks decreased significantly with the increase of alfalfa meal levels (p<0.05). This experiment showed that feeding of alfalfa meal to growing layer ducks could improve gastrointestinal tract growth and small intestinal morphology without effect on performance. This experiment provides evidence that alfalfa meal is a very valuable feedstuff for growing layer ducks.

A 4-week energy balance study was conducted to estimate the energy expenditure (EE) of 16 college age men and women, 20 to 26 year of age, by measurement of energy intakes and changes in body energy(BE) content(intake/balance technique), keeping their normal living pattern and maintenance body weight. Energy intake was measured by bomb calorimetry and estimated by food table. Fecal energy loss was calculated from nitrogen excreted. Fat mass was determined from body density estimated from skinfold tickness. 1) Gross energy (GE) intakes calculated from food table was not only 13.4% lower than those of bomb calorimetry but also lower 4 and 5% than metabolizable energy(ME) intakes for the male and female subjects, respectively. 2) Fecal energy loss was 7.2% and 6.9% proportion of the gross energy intake for the male and female subjects, respectively. 3) Mean daily metabolizable energy intakes estimated by subtract fecal and urinary energy loss was 2467kcal for the male subjects and 1897kcal for the female subjects. 4) Total body energy change estimated from body composition change over 31 days was decreased 7672kcal for the male subjects and 2689kcal for the female subjects. 5) Mean daily energy expenditure was 2714kcal (45kcal/kg of body weight) for the male subjects and 1984kcal(40kcal/kg of body weight) for the female subjects. 6) The estimated energy expenditure of college-age subjects in this study provide evidence to support the Recommended Dietary Allowances for energy of Korean normal adult.

Combining basal insulin therapy with a glucagon-like peptide-1 receptor agonist (GLP-1 RA) has clear clinical advantages, and is supported by the latest EASD/ADA position statement (1). IDegLira is a once-daily combination of the basal insulin, degludec, and the GLP-1RA, liraglutide, in one pen. The DUAL phase 3 clinical trial program provides important evidence about the efficacy and safety of IDegLira in three different populations of patients with type 2 diabetes (T2D): insulin naïve subjects uncontrolled on oral antidiabetic drugs (OADs), subjects uncontrolled on OAD(s) and a GLP-1 RA, and subjects uncontrolled on OAD(s) and basal insulin. Treatment with IDegLira reduced mean HbA1c to below the EASD/ADA treatment target of 7.0% in all five trials. The mean reduction of HbA1c from baseline ranged from 1.3% and 1.9%. IDegLira resulted in weight loss for subjects uncontrolled on basal insulin, was weight neutral for subjects on OADs and weight gain was minimal (2 kg) for subjects previously treated with a GLP-1 RA. Rates of hypoglycaemia were low across all the trials, particularly considering the level of glycaemic control achieved.
