The aim of this study was to investigate the sleep-promoting effect of a Valerian/Hops mixture in fruit flies. The HPLC analysis showed that Valerenic acid (1260.53 μg/g of extract) and Xanthohumol (Cascade: 827.49 μg/g, Hallertau: 763.60 μg/g, Saaz: 186.93 μg/g) were contained in Valerian and Hop, respectively. The sleep patterns of fruit flies on the Valerian/Hops were examined in both baseline and caffeine-treated conditions. Total activities of flies significantly decreased in 20 mg/mL Valerian (74%), 10 mg/mL Cascade (25%), and 5 mg/mL Hallertau (11%) during nighttime or daytime compared with the control. Valerian/Cascade mixture showed longer sleeping time (ca. 20%) than control group. This mixture-mediated effect was partly observed in caffeine-treated flies. Valerian/Cascade mixture upregulated mRNA expressions of gamma-aminobutyric acid (GABA) receptors and serotonin receptor, and GABA receptors were more strongly regulated than serotonin receptor. In competitive GABA receptor binding assay, Valerian/Cascade mixture extract showed a higher binding ability on GABA receptor than Valerenic acid or/and Xanthohumol which are estimated to be active compounds in the extract. This study demonstrates that a Valerian/Cascade mixture extract improves sleep-related behaviors, including sleeping time, by modulating GABAergic/serotonergic signaling. © 2017 The Pharmaceutical Society of Japan.

We hypothesized that the administration of explosion-puffed coffee, containing γ-aminobutyric acid (GABA) and 5-hydroxytryptophan (5-HTP), would be associated with a reduction of the caffeine effect on sleep behavior and behavioral patterns, which was investigated in a Drosophila model. The effects of feeding roasted coffee beans (RB), explosion-puffed coffee beans puffed at 0.75. MPa and 0.9. MPa (PB 7.5 and PB 9.0, respectively), or decaffeinated coffee beans (DeRB) on locomotor activity and behavioral patterns of Drosophila was analyzed. In the decreasing order, the total chlorogenic acid (caffeoylquinic acids, CQA) content was PB 7.5. >. PB 9.0. >. RB. PB content analysis showed high levels of GABA and 5-HTP, compared with that of RB, which corresponded with the sleep-wake behavior of Drosophila. The RB and PB (PB 7.5 and PB 9.0) groups were not significantly different with respect to an activity count during the subjective night and day period compared with the normal controls. Sleep bout numbers of the normal, PB, and DeRB groups showed significant differences as compared with the caffeine and RB groups (p <. 0.05). The PB and DePB groups showed a significantly increased transcript levels for the GABA receptors compared to the caffeine group. The caffeine and RB groups displayed better climbing ability than the other groups, covering an average distance 6. cm in the related test; the average distance covered by the normal, PB 7.5, and DeRB groups was <. 4. cm. The normal and DeRB groups showed similar behavior patterns with respect to total distance, velocity, moving, not moving, and meander. However, the PB 7.5 group significantly regulated not moving and meander of flies compared to flies receiving only caffeine and RB. Suppression of the stimulating effect of caffeine by explosion-puffed coffee administration was indicated in the above results, which can be attributed to the increased content of GABA and 5-HTP with explosive puffing process carried out at 0.75. MPa. Results of the underlying mechanism of the behavioral change patterns of explosive puffed with or without caffeine in Drosophila models, transcript level for the Dop1-R1 receptor in caffeine group was significantly higher than normal, PB, and DePB groups. Flies exposed to the caffeine had significantly decreased transcript levels for the GABA receptors. PB 7.5 and DePB showed higher level of GABA content than RB. © 2017.

A mixed composition of purified β-glucan from Aureobasidium pullulans and calcium lactate-gluconate 1: 9(g/g) (polycalcium) was administered orally to female and male Sprague-Dawley (SD) rats once per day for 14 days at doses of 0, 500, 1,000 and 2,000 mg/kg in a volume of 10 mL/kg to investigate the effects of an oral repeated dose. After 14 days of oral polycalcium treatment, no treatment-related mortalities, clinical signs, or body/organ weight changes were detected. In addition, no meaningful polycalcium treatment-related changes were observed in hematological, serum biochemical, gross or histopathological parameters as compared with sex-matched vehicle controls following treatment with doses up to 2,000 mg/kg, the maximum dose limit for rodents. Therefore, polycalcium is non-toxic to rats and is therefore likely to be safe for clinical use. © 2014, Korean Society of Environmental Risk Assessment and Health Science and Springer Science+Business Media Dordrecht.

In the present study, the beneficial and synergistic effects of Polycalcium, a mixture of Polycan and calcium (Ca) lactate-gluconate in a 1:9 weight ratio, on a rat model of osteoarthritis (OA) were explored. Polycalcium (50, 100 and 200 mg/kg) was administered orally once per day for 28 days from 1 week after the OA-modeling surgery. Diclofenac sodium (2 mg/kg) was administered as a reference drug. Following the OA surgery, increases in the maximum extension angles, edematous changes in knee and capsule thickness, reductions in chondrocyte proliferation and cartilage glycosaminoglycan (GAG) levels, as well as changes in cartilage degeneration were observed. However, these OA-related symptoms were inhibited after 28 days of continuous oral treatment with Polycalcium. Anti-OA effects, including the induction of chondrocyte proliferation, were detected in the Polycalcium-treated rats and were more favorable compared with those in rats treated with Polycan or Ca lactate-gluconate alone (100 mg). Therefore, a mixture of Polycan and Ca lactate-gluconate was demonstrated to have beneficial synergistic effects on OA. © 2015 Spandidos Publications. All rights reserved.

Background/Aims: Although controversial, probiotics and dietary fiber are commonly used for patients with irritable bowel syndrome (IBS). We evaluated the effects of multistrain probiotics on the symptoms of IBS to determine whether the addition of dietary fiber had an additive effect on constipation-predominant IBS. Methods: A total of 142 participants who met the Rome III criteria were recruited and randomized into a control group or a test group. Participants in the control group received multistrain probiotic fermented milk with Streptococcus thermophilus, Lactobacillus acidophilus and Bifidobacterium infantis; the participants in the test group received the same probiotic fermented milk mixed with dietary fiber such as sea tangle extracts, radish extracts and glasswort extracts. The patients were treated for four weeks. Results: Most of the symptoms of IBS, with the exception of flatulence, stool consistency, and frequency of defecation, significantly improved in both groups. In the analysis of IBS subtypes, especially constipation-predominant IBS, the frequency and duration of defecation and straining at stool were improved more in the test group than in the control group. Conclusions: Dietary fiber had additive benefits for the symptoms of constipation, especially in constipation-predominant IBS.

Acrylamide in foods is mainly produced by Maillard reaction. Taurine can participate in the reaction, which has led us to investigate the possibility of reducing acrylamide formation by use of taurine. In an aqueous system, the lower the pH of the solution the greater the inhibition of acrylamide formation within a pH range of 5.0-8.0 was found, and the inhibition of acrylamide formation by taurine was dose-dependent. In a fried potato chip model, prior to frying at 170°C for 3. min, the potato slices soaked in 0.l% to 2% taurine solution for 30. min showed significant reductions of acrylamide formation; however, these reductions were not dose-dependent. Also, the soaking treatments for 15-60. min significantly reduced acrylamide formation, but the inhibitory effects were not time-dependent. Thus, taurine, when used in a narrow range of reasonably low levels, is a candidate to inhibit acrylamide formation during frying process. © 2010 Elsevier Ltd.

In this work, we wanted to develop a probiotic from famous longevity villages in Korea. We visited eight longevity villages in Korea to collect fecal samples from healthy adults who were aged above 80 years and had regular bowel movements, and isolated lactic-acid–producing bacteria from the samples. Isolated colonies that appeared on MRS agar containing bromophenol blue were identified by means of 16S rRNA sequencing, and 102 of the isolates were identified as lactic-acid–producing bacteria (18 species). Lactobacillus fermentum was the most frequently found species. Eight isolates were selected on the basis of their ability to inhibit the growth of six intestinal pathogens (Escherichia coli O157:H7, Salmonella enterica subsp. enterica Typhimurium, Salmonella enterica subsp. enterica Enteritidis, Enterococcus faecalis, Staphylococcus aureus, and Listeria monocytogenes) and their susceptibility to 15 antimicrobial agents. Among these eight isolates, four Lactobacillus fermentum isolates were found not to produce any harmful enzymes or metabolites. Among them, Lactobacillus fermentum isolate no. 24 showed the strongest binding to intestinal epithelial cells, the highest immune-enhancing activity, anti-inflammation activity, and anti-oxidation activity as well as the highest survival rates in the presence of artificial gastric juice and bile solution. This isolate, designated Lactobacillus fermentum PL9988, has all the characteristics for a good probiotic. © 2015 by The Korean Society for Microbiology and Biotechnology.
