  • Both the calcium and collagen in bone powder are hard to be absorbed by the body. Although enzymatic hydrolysis by protease increased the bio-availability of bone powder, it was a meaningful try to further increase $Ca^{2+}$ release, oligopeptide formation and antioxidant activity of the sheep bone hydrolysate (SBH) by lactic acid bacteria (LAB) fermentation. Lactobacillus helveticus was selected as the starter for its highest protease-producing ability among 5 tested LAB strains. The content of liberated $Ca^{2+}$ was measured as the responsive value in the response surface methodology (RSM) for optimizing the fermenting parameters. When SBH (adjusted to pH 6.1) supplemented with 1.0% glucose was inoculated 3.0% L. helveticus and incubated for 29.4 h at $36^{\circ}C$, $Ca^{2+}$ content in the fermented SBH significantly increased (p<0.01), and so did the degree of hydrolysis and the obtaining rate of oligopeptide. The viable counts of L. helveticus reached to $1.1{\times}10^{10}CFU/mL$. Results of Pearson correlation analysis demonstrated that LAB viable counts, $Ca^{2+}$ levels, obtaining rates of oligopeptide and the yield of polypeptide were positively correlated with each other (p<0.01). The abilities of SBH to scavenge the free radicals of DPPH, OH and ABTS were also markedly enhanced after fermentation. In conclusion, L. helveticus fermentation can further boost the release of free $Ca^{2+}$ and oligopeptide, enhance the antioxidant ability of SBH. The L. helveticus fermented SBH can be developed as a novel functional dietary supplement product.

  • The objective of this study was to compare nutrients intake, health indices, and prevalence of chronic diseases by occupation in middle-aged men, using results from National Health and Nutrition Examination Survey. The subjects were divided into two groups by their occupation (Office worker (OW) and Agri-fishery worker (AFW)) and their percentages were 75.5% and 24.5% respectively. In health-related factors, drinking rate was higher in OW (p<0.001), while smoking rate was higher in AFW (p<0.001). Walking and strength exercise were both higher in OW group. In dietary behavior, the rate of skipping breakfast and eating out was higher in OW (p<0.001). Food supplement usage were consumed by OW more than AFW (p<0.001). Daily energy intake was higher in AFW (p<0.05). There were significant differences in nutrient density per 1,000 kcal of minerals and vitamins between the two groups (p<0.05~p<0.001), except calcium, potassium, vitamin A and thiamin. In body weight, BMI, waist circumference and blood pressures, OW was higher than AFW (p<0.05~p<0.001). Whereas, HDL and LDL-cholesterol were higher in AFW (p<0.001). The prevalence of diabetes was higher in AFW (p<0.001). The results of this study can be used as data to establish nutrition and health strategies for occupation in middle-aged men.

  • Objective: The objective of this study was to investigate the effect of bamboo grass (Tiliacora triandra, Diels) pellet (Bamboo-Cass) supplementation on feed intake, nutrient digestibility, rumen microbial population and methane production in Thai native beef cattle. Methods: Four Thai native beef cattle bulls ($190{\pm}2kg$) were randomly allotted to four respective dietary treatments in a $4{\times}4$ Latin square design. Treatments were the varying levels of Bamboo-Cass supplementation at 0, 50, 100, and 150 g/head/d, respectively. Rice straw was fed ad libitum and the concentrate offered at 0.5% of body weight. Results: Under this experiment, the findings revealed that acetate and butyrate production were decreased (p<0.05), propionate increased (p<0.05), whilst ruminal $NH_3-N$ concentration was decreased (p<0.05) by supplementation of Bamboo-Cass at 150 g/head/d. Moreover, rice straw intake, and microbial population were linearly increased (p<0.05), while methane production was decreased (p<0.05). Conclusion: The results from the present study indicate that supplementation of Bamboo-Cass at 150 g/head/d significantly enhanced feed intake, decreased protozoa and increased bacterial population, rumen fermentation efficiency while decreased methane production. Therefore, Bamboo-Cass as a supplement is promising as a rumen enhancer in beef cattle fed on rice straw.

  • This experiment was conducted to investigate the effect of Cordyceps militaris with probiotics (CMP) supplementation on the growth performance, meat quality and storage characteristics, and cordycepin content in the meat. Sixty one-day-old broilers (Ross 308) were allotted to two treatment groups of 30 each. In addition, six broilers were randomly assigned to a cage in the two treatment groups. The two dietary treatments were as follows: Control (CON) and basal diet + 0.5% of CMP. Body weight and feed intake were measured on the 1st, 14th, and 28th days from the start of the experiment. On days 1 - 14, the supplementation of CMP improved (p < 0.05) the body weight gain (BWG) and feed conversion ratio (FCR). Additionally, the feed intake (FI) and FCR scores in the CMP groups improved (p < 0.01) compared to the CON during the entire period. For the meat quality characteristics, water holding capacity (WHC), cooking loss (CL), redness (a*) in meat color value, and shearing force (SF) for the CMP group were improved (p < 0.01) compared to the CON group. For the meat storage characteristics, pH and thiobarbituric acid reactive substances (TBARS) were improved (p < 0.01) when the broilers were fed CMP compared to the CON group. Broilers fed CMP had a higher (p < 0.01) cordycepin content in the meat compared to the CON group. In conclusion, CMP improves the growth performance and meat quality of broilers.

  • Eisenia bicyclis is known to have secondary metabolites exhibiting various biological activities. In a preliminary study, the n-hexane fraction obtained from the ethanolic extract of E. bicyclis showed higher anti-inflammatory activity than the ethyl acetate and butyl alcohol fractions based on the inhibition of lipopolysaccharide (LPS)-stimulated nitric oxide (NO) production in RAW 264.7 cells. Using this fraction (E. bicyclis hexane fraction, EHF), we investigated the molecular mechanisms underlying its anti-inflammatory effect in LPS-stimulated RAW 264.7 cells. Pretreatment of the cells with up to 50 ㎍/mL EHF significantly inhibited NO and prostaglandin E2 production as well as their responsible enzyme proteins and mRNAs, in a dose-dependent manner (P<0.05). Similarly, EHF markedly reduced the production of pro-inflammatory cytokines, such as interleukin (IL)-1β, IL-6 and tumor necrosis factor (TNF)-α as well as their mRNA levels. Nuclear translocation of nuclear factor-kappa B (NF-κB) was strongly suppressed by EHF treatment. EHF significantly reduced the phosphorylation of mitogen-activated protein kinases and phosphatidylinositol 3-kinase/Akt in LPS-stimulated cells. Moreover, EHF reduced ear edema in phorbol myristate acetate (PMA)-induced mice. These results indicate that EHF contains potent anti-inflammatory compounds, which may be used as a dietary supplement for the prevention of inflammatory diseases.

  • INTRODUCTION: Regulation of skeletal muscle protein mass is implicated not only in exercise performance but in metabolic health. Exercise in combination with nutrition, particularly dietary protein/amino acid intake, are the pragmatic approach that effectively induces muscle anabolic response (i.e., muscle hypertrophy) through regulating protein synthesis and breakdown. PURPOSE: The purpose of this review was to summarize available data on the effect of exercise intervention and amino acids intake on muscle protein synthesis and breakdown and provide an insight into development of an effective exercise intervention and amino acids supplements, applicable to training practice. METHODS: In this review, we have reviewed currently available data mainly from stable isotope tracer studies with respect to the effect of exercise intervention and protein or amino acid supplement on muscle protein anabolic response. CONCLUSIONS: Taken together, exercise alone may not be effective in achieving a positive net muscle protein balance due to the fact that protein breakdown still exceeds protein synthesis until nutrition intake such as protein/amino acids. It appears that muscle anabolic response increases in proportional to the amount of protein intake up to 20 - 35 g depending on quality of protein, age, differences on exercise intensity, duration, and frequency, and individual's training status

  • Ascites is the accumulation of fluid in the peritoneal cavity, and it is generally allied with liver disease like cirrhosis of the liver. The ascites is commonly associated with liver cirrhosis, malignancy, or cardiovascular disease today. The liver cirrhosis is the most significant cause of ascites in developed countries as per the available data. In the modern medicine system, the treatment includes the restriction of sodium intake, use of diuretics, and paracentesis done in severe cases. There are many side effects of synthetic chemical diuretics, and their long-term use is not recommended. The alternative medicine like Unani system of medicine provides natural diuretics and drugs which also have protective effects on kidney, liver and other internal organs. It is well known in all drug systems that the prognosis is poor in ascites, but the use of Unani herbal medicines can minimize the side effects caused by synthetic chemical diuretics. The natural herbs used for the management of ascites have fewer side effects as compared to synthetic drugs. The natural drugs can be used for longer duration and provide some dietary supplement which improves the quality of life. This review addressed the thorough treatment of ascites by natural diet and medications.

  • Pycnogenol is used as a dietary supplement based on various medical research studies suggesting health benefits. In recent years, it has also been used in cosmetic products, but the clinical research on its dermatologic effects has been insufficient. This study was designed to determine the effectiveness of pycnogenol topically applied to skin of individuals with acne in their teens and twenties. Cosmetics containing 0.2% pycnogenol were applied to a group of 11 clinical subjects for 6 weeks and their skin conditions were assessed. The group that used cosmetics with pycnogenol showed decrease in P-Acnes, acne causing bacteria, phorphyrin index, a metabolite, and the pigmentation and redness index. This study confirms that pycnogenol extract is effective dermatologically in decreasing acne bacteria and reducing redness and pigmentation of skin affected by acne.

  • Panax ginseng is one of the most important herbal medicinal plants consumed as health functional food and can be fermented to achieve better efficacy. Lacticaseibacillus, one of the representative genera among lactic acid bacteria (LAB), has also been used as a probiotic material for health functional foods due to its beneficial effects on the human body. To achieve a synergistic effect by using these excellent dietary supplement ingredients together, a novel LAB strain was isolated from the root of 6-year-old ginseng. Through similarity analysis of 16S rRNAs and whole-genome sequences, the strain was confirmed as belonging to the genus Lacticaseibacillus and was named L. casei KGC1201. KGC1201 not only met all safety standards as food, but also showed excellent probiotic properties such as acid resistance, bile salt resistance, and intestinal adhesion. In particular, KGC1201 exhibited superior acid resistance through morphological observation identifying that the cell surface damage of KGC1201 was less than that of the L. casei type strain KCTC3109. Gene expression studies were conducted to elucidate the molecular mechanisms of KGC1201's acid resistance, and the expression of the glycosyltransferase gene was found to be significantly elevated under acidic conditions. Exopolysaccharides (EPSs) biosynthesized by glycosyltransferase were also increased in KGC1201 compared to KCTC3109, which may contribute to better protection of KGC1201 cells from strong acidity. Therefore, KGC1201, with its increased acid resistance through molecular mechanisms and excellent probiotic properties, can be used in health functional foods to provide greater benefit to overall human health and well-being.
