BACKGROUND/OBJECTIVES: The leaves of Moringa oleifera (MO) and Moringa stenopetala (MS) commonly grown in Ethiopia possess potential nutritional and medicinal value. The aim of this study was to evaluate the nutritional and functional characteristics of the dried leaf powder from two Moringa species to develop sustainable nutritional supplements for Ethiopians from locally grown plant sources. MATERIALS/METHODS: Freshly harvested and air-dried MO and MS leaves were authenticated and the nutritional contents, such as protein, ash, lipids, and selected vitamins and minerals, were analyzed using standard analytical procedures. Amino acid compositions were also determined by an amino acid analyzer. Nine-week-old mice were randomly divided into four groups to investigate the anti-obesity effects of Moringa. The first group was fed a basal diet, the second group a high-fat diet, and the others were fed a high-fat diet containing 0.1% Moringa leaf powder from each species. After seven weeks, serum indices related to lipid profiles from each mouse were analyzed. RESULTS: The present study revealed high protein (28-29%) and ash (7-11%) contents. Glutamic acid, aspartic acid, proline, and leucine were the most abundantly found amino acids in both species. The predominant minerals in the leaf powder were calcium (826-1,530 mg/100 g), potassium (794-904 mg/100 g), and magnesium (286-431 mg/100 g). Pyridoxine (475.06 mg/100 g) and vitamin E (34.2 mg/100 g) were found only in MS. Niacin was found only in MO at 32.21 mg/100 g, whereas ascorbic acid was found in both species (3.89 and 6.19 mg/100 g dry weight for MO and MS, respectively). The results of the animal study showed that mice on a high-fat diet containing 0.1% MO leaf powder alleviated the elevation of cholesterol, triglycerides, and low-density lipoprotein cholesterol induced by the high fat diet. MO was more effective than MS in preventing hypercholesterolemia and fat deposition. CONCLUSION: The findings in this work confirmed that Moringa leaves of both MO and MS possessed high nutritional value but MO was better at preventing the harmful effects of the high-fat diet than MS.
Objectives : Obesity is a public health concern associated with chronic diseases including hyperlipidemia, diabetes, fatty liver, atherosclerosis and cancer. As several anti-obesity drugs have been limited owing to their side effects, the development of new anti-obesity drugs through herbal medicines has been increasing. Cynanchum Wilfordii Radix (CW) traditionally is consumed for various health benefits including immune enhancing, anti-inflammation and anti-tumor activities. The aim of the present study is to evaluate the effects of CW on High fat diet (HFD)-induced obese mice. Methods : The mice were randomly divided into four groups (n=7). The mice were respectively fed a normal diet (ND), a high-fat diet (HFD), HFD plus CW (50 mg/kg/day), HFD plus CW (100 mg/kg/day). All groups were assayed for body weights, food efficiency ratio, blood biochemistry parameters, and organic tissue weights. Results : HFD-fed mice showed an increase in the body weight and serum biochemistry parameters levels (total cholesterol and triglycerides) as well as organic tissue weights. However, the administration of CW to obese mice induced a reduction in their body weight, food efficiency ratio, blood biochemistry parameters and weight of liver and fat compared with the HFD fed mice. Additionally, we observed that CW inhibited the lipid accumulation in liver and serum lipid parameter induced by HFD. Conclusions : Taken together, the findings of this study suggest that CW may be a potential agent for use in the treatment of obesity and obesity-related metabolic diseases.

BACKGROUND/OBJECTIVES: The effectiveness of natural compounds in improving athletic ability has attracted attention in both sports and research. Gynostemma pentaphyllum (Thunb.) leaves are used to make traditional herbal medicines in Asia. The active components of G. pentaphyllum, dammarane saponins, or gypenosides, possess a range of biological activities. On the other hand, the anti-fatigue effects from G. pentaphyllum extract (GPE) and its effective compound, gypenoside L (GL), remain to be determined. MATERIALS/METHODS: This study examined the effects of GPE on fatigue and exercise performance in ICR mice. GPE was administered orally to mice for 6 weeks, with or without treadmill training. The biochemical analysis in serum, glycogen content, mRNA, and protein expressions of the liver and muscle were analyzed. RESULTS: The ExGPE (exercise with 300 mg/kg body weight/day of GPE) mice decreased the fat mass percentage significantly compared to the ExC mice, while the ExGPE showed the greatest lean mass percentage compared to the ExC group. The administration of GPE improved the exercise endurance and capacity in treadmill-trained mice, increased glucose and triglycerides, and decreased the serum creatine kinase and lactate levels after intensive exercise. The muscle glycogen levels were higher in the ExGPE group than the ExC group. GPE increased the level of mitochondrial biogenesis by enhancing the phosphorylation of peroxisome proliferator-activated receptor-γ coactivator-1α (PGC-1α) protein and the mRNA expression of nuclear respiratory factor 1, mitochondrial DNA, peroxisome proliferator-activated receptor-δ, superoxide dismutase 2, and by decreasing the lactate dehydrogenase B level in the soleus muscle (SOL). GPE also improved PGC-1α activation in the SOL significantly through AMPK/p38 phosphorylation. CONCLUSIONS: These results showed that GPE supplementation enhances exercise performance and has anti-fatigue activity. In addition, the underlying molecular mechanism was elucidated. Therefore, GPE is a promising candidate for developing functional foods and enhancing the exercise capacity and anti-fatigue activity.

Objective: The objective of this study was to investigate the effect of supplementation with enzymolytic soybean meal (ESBM) on broilers fed low crude protein (CP) diets. Methods: A total of 360 one-day-old broilers were randomly assigned to six treatments with 6 replicates per treatment and 10 chicks per replicate for a period of 42 days. Chicks were fed a basal standard high-CP diet as a positive control (PC), a low-CP diet (reducing 10 g/kg CP from the PC) as a negative control (NC), or an NC + 0.5%, 1.0%, 1.5%, or 2.0% ESBM diet. Results: Compared to chicks fed the PC, chicks fed the NC had a decreased body weight gain (BWG, p<0.05) from 1 to 42 days, but supplementation with 2.0% ESBM restored BWG (p<0.05) and even linearly improved the feed conversion rate (FCR, p<0.05). Digestibility of CP and ether extract was increased (p<0.05) in chicks fed a 1.0% ESBM diet compared to the PC. With increasing levels of ESBM, nitrogen (N) excretion decreased (p<0.05). The addition of ESBM to the diet did not affect (p>0.05) serum concentrations of total protein, albumin and total cholesterol but led to a descending trend in triglycerides and an ascending trend in calcium and urea N at 42 days (p<0.10). There were no differences (p>0.05) in villus height (VH), crypt depth (CD), and VH/CD (V/C) of the duodenum and jejunum between the PC and NC at both 21 days and 42 days, while increasing dietary ESBM levels linearly (p<0.05) decreased CD and increased V/C of the duodenum and jejunum at both 21 days and 42 days. Conclusion: The findings indicated that ESBM could be used in broiler low-CP diets to improve production performance, decrease N excretion, and enhance intestinal health.

BACKGROUND/OBJECTIVES: Activating brown adipose tissue (BAT) and browning of white adipose tissue (WAT) can protect against obesity and obesity-related metabolic conditions. Cryptotanshinone (CT) regulates lipid metabolism and significantly ameliorates insulin resistance. Adenosine-5'-monophosphate (AMP)-activated protein kinase (AMPK), a receptor for cellular energy metabolism, is believed to regulate brown fat activity in humans. MATERIALS/METHODS: The in vivo study included high-fat-fed obese mice administered orally 200/400 mg/kg/d CT. They were evaluated through weight measurement, the intraperitoneal glucose tolerance test (IPGTT), intraperitoneal insulin tolerance test (IPITT), cold stimulation test, serum lipid (total cholesterol, triglycerides, and low-density lipoprotein) measurement, hematoxylin and eosin staining, and immunohistochemistry. Furthermore, the in vitro study investigated primary adipose mesenchymal stem cells (MSCs) with incubation of CT and AMPK agonists (acadesine)/inhibitor (Compound C). Cells were evaluated using Oil Red O staining, Alizarin red staining, flow cytometry, and immunofluorescence staining to identify and observe the osteogenic versus adipogenic differentiation. Quantitative real-time polymerase chain reaction and the Western blot were used to observe related gene expression. RESULTS: In the diet-induced obesity mouse model mice CT suppressed body weight, food intake, glucose levels in the IPGTT and IPTT, serum lipids, the volume of adipose tissue, and increased thermogenesis, uncoupling protein 1, and the AMPK pathway expression. In the in vitro study, CT prevented the formation of lipid droplets from MSCs while activating brown genes and the AMPK pathway. AMPK activator enhanced CT's effects, while the AMPK inhibitor reversed the effects of CT. CONCLUSION: CT promotes adipose tissue browning to increase body thermogenesis and reduce obesity by activating the AMPK pathway. This study provides an experimental foundation for the use of CT in obesity treatment.
Obesity and overweight pose a significant public health problem, as they are associated with an elevated risk of metabolic syndrome (MetS). Several studies have shown that diet quality is associated with the development of MetS risk factors. Analyzing dietary patterns may be more helpful in determining the relationship between eating habits and chronic diseases compared to focusing on single foods or nutrients. In this study, our objective was to evaluate the association of food quality score (FQS) with risk factors for MetS in individuals with obesity and overweight. The participants in this cross-sectional study were 340 adults with overweight and obesity. Participants' food intake was measured using a Food Frequency Questionnaire, then the FQS was calculated. A fasting blood sample assessed serum glucose, triglycerides, total cholesterol (TC), high-density lipoprotein cholesterol, and serum insulin levels. Fat-free mass, height, basal metabolic rate, socio-economic score, and waist-to-hip ratio significantly differed among FQS tertiles. TC, systolic and diastolic blood pressure, and fasting blood glucose were significantly lower in the highest tertile of FQS. After multivariable adjustment, our results showed that individuals in the third tertile of FQS had reduced risk of higher levels of TC (odds ratio [OR], 0.982; 95% confidence interval [CI], 0.970-0.984) and higher levels of low-density lipoprotein cholesterol (OR, 0.974; 95% CI, 0.974-0.999). Our findings demonstrate an inverse relationship between diet quality, as measured by FQS, and MetS risk factors. However, further experimental and longitudinal investigations are warranted to elucidate the causal nature of this association.
The present study was conducted to determine the effects of L-carnosine (LC) and/or alpha-lipoic acid (ALA) supplementation on growth performance, blood thyroid hormones and lipid profiles in finishing pigs. A total of 40 ($Landrace{\times}Yorkshire$) pigs with an initial body weight of $57.93{\pm}3.14kg$ were randomly allocated to 4 experimental diets using a $2{\times}2$ factorial arrangement with 2 LC supplemental levels (0 or 0.1%) and 2 ALA supplemental levels (0 or 0.03%) in basal diets. The results showed that pigs fed LC-supplemented diets increased final live weight, average daily gain, and average daily feed intake compared to those of pigs fed without LC-supplemented diets (p<0.05). Dietary supplementation with ALA did not affect the growth performance and carcass traits of pigs (p>0.05). Additionally, LC supplementation increased serum triiodothyronine, thyroxine levels, and ALA supplementation increased serum triiodothyronine levels (p<0.05). Serum total cholesterol and triglycerides levels were significantly decreased in LC and ALA supplemented groups, respectively (p<0.05). Moreover, serum low density lipoprotein cholesterol levels were lower in the ALA-supplemented groups than those of pigs fed without ALA-supplemented diets (p<0.05). However, no significant $LC{\times}ALA$ interaction effect on growth performance, blood thyroid hormones and lipid profiles was found. This study suggested that dietary supplementation of LC resulted in better growth performance compared to that of ALA supplementation. L-carnosine and/or ALA supplementation positively modified blood lipid profiles, which may have the potential to prevent cardiovascular diseases.

This study was designed to evaluate the effect of a rice-based diet on body weight and serum lipid levels. Thirty male C57BL/6 mice were randomly divided into three groups and fed a high-fat diet (HFD), rice-based diet (RD), or bread-based diet (BD) for five weeks. Our results showed that the RD group had a significantly lower final body weight, although there was no significant difference in daily food intake among the groups. There was a reduction in body weight gains, adipose tissues weight, and adipocyte size of epididymal adipose tissue in the RD group (p<0.05). Also, serum triglycerides and total cholesterol in the RD group were significantly decreased compared to the BD group. RD also reduced fasting glucose and insulin levels. These results indicate that the intake of RD attenuates increases in body weight and serum lipid concentrations in mice, suggesting its benefits for the dietary control of obesity and hyperlipidemia.

The effects of a 12-week weight reduction program applied to obese women at a community health center were studied. Middle aged women participated in the beginning of the program, but 34 persons finished the study (85% completion). Subjects practiced belly dancing three times a week for 60 minutes (60~85% HR max) per session, and nutritional education was carried out four times during the 12 week program. The weight, %body fat, and BMI significantly decreased by 5.6%, 9.5%, and 5.6%, respectively. The concentrations of serum triglycerides, total cholesterol, and LDL-C were also significantly reduced by 13.5%, 9.5%, and 10.4%, respectively. Insulin level was reduced by 19.8%, thus lowering the HOMA-IR index. Leptin level significantly was reduced by 32.35%, adiponectin concentration. Total ROS concentration increased while total antioxidant capacity in serum remained unchanged. In conclusion, a 12-week 'Obesity Clinic Program' belly dancing and nutritional education held at a Community Center seemed to have health-promoting effects through reducing body fats, plasma lipids, and improving insulin resistance.
The purpose of this study was to investigate the changes of body composition, serum lipids and several parameters of body fatness (percent body fat, waist-hip ratio) in abdominal women by exercise. For this study, 8-weeks intensive exercise(5km jogging/day, 50min/day) was continued by subjects and they limited only fat rich foods and controlled daily energy intake to 1,800kcal~2,100kcal per day. The subjects were 52 women and the distribution of ages was 36~54 years. The data were analyzed using SPSS/PC package program and the results were estimated by paired t-test, Pearson correlation. The results are summarized as follows : 1) After exercise-training for 8 weeks, percent body fat, body mass index, body weight, total cholesterol was decreased (p<0.05). 2) LDL cholesterol and triglyceride was decreased significantly(p=0.000). The changes in deep abdominal adipose tissue were related to changes in triglycerides. 3) After exercise training, the waist-hip ratio was significantly correlated to body weight and serum lipids. 4) According to the data of this study, Ⅰ recommended that obese women, especially, abdominal obese patients should exercise regularly and we should prolong many studies for obesity.
