In vitro anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe grade black tea (Camellia sinensis L.)

ObjectiveTo access the anti-hyaluronidase activity of Sri Lankan low grown orthodox orange pekoe (OP) grade black tea with a view to develop an anti-aging skin formulation.MethodsFive concentrations (0.125, 0.250, 0.500, 1.000 and 2.000 mg/mL) of black tea brew (BTB) were made using a freeze dried sample of Sri Lankan low grown orthodox OP grade black tea which was prepared according to international organization for standardization specification. Epigallocatechin gallate (EGCG) was used as the reference agent (concentrations tested: 0.012, 0.025, 0.050, 0.100 and 0.200 mg/mL). Anti-hyaluronidase activity of BTB and EGCG in vitro were ascertained spectrometrically using hyaluronic acid (from rooster comb) and bovine testicular hyaluronidase.ResultsThe results revealed that BTB had moderate [IC₅₀=(1.09±0.12) mg/mL] and dose dependent (r²=0.94) anti-hyaluronidase activity. EGCG also exhibited dose dependent (r²=0.93, P<0.05) anti-hyaluronidase activity which was superior [IC₅₀=(0.09±0.00) mg/mL] to BTB.ConclusionsSri Lankan low grown orthodox OP grade black tea has promising anti-hyaluronidase activity in vitro and has the potential to be used as an anti-aging cosmaceutical. In addition, it may prove useful as a beverage in the management of allergy, some joint diseases and envenomation.

Evaluation of the Protein Requirement in Chinese Young Adults Using the Indicator Amino Acid Oxidation Technique

ObjectiveTo accurately calculate the protein requirements in Chinese young adults using the indicator amino acid oxidation technique.MethodsNine women and ten men received a restricted daily level of protein intake (0.75, 0.82, 0.89, 0.97, and 1.05 g/kg), along with L-[1-¹³C]-leucine. Subjects' protein requirement was determined by a biphasic linear regression crossover analysis of F¹³CO₂ data. In doing so, a breakpoint at the minimal rate of appearance of ¹³CO₂ expiration specific to each level of dietary protein was identified. This trial was registered with the Chinese clinical trial registry as ChiCTR-ONC-11001407.ResultsThe Estimated Average Requirement (EAR) and the Recommended Nutrient Intake (RNI) of protein for healthy Chinese young adults were determined to be 0.87 and 0.98 g/(kg·d), respectively, based on the indicator amino acid oxidation technique.ConclusionThe EAR and RNI of mixed protein are 5% and 16% that are lower than the current proposed EAR and RNI (0.92 and 1.16 g/(kg·d), respectively), as determined by the nitrogen balance method. The respective EAR and RNI recommendations of 0.87 and 0.98 g/(kg·d) of mixed protein are estimated to be reasonable and suitable for Chinese young adults.

Proteomics analysis of antimalarial targets of Garcinia mangostana Linn.

ObjectiveTo investigate possible protein targets for antimalarial activity of Garcinia mangostana Linn. (G. mangostana) (pericarp) in 3D7 Plasmodium falciparum clone using 2-dimensional electrophoresis and liquid chromatography mass-spectrometry (LC/MS/MS).Methods3D7 Plasmodium falciparum was exposed to the crude ethanolic extract of G. mangostana Linn. (pericarp) at the concentrations of 12μg/mL (IC₅₀ level: concentration that inhibits parasite growth by 50%) and 30 μg/mL (IC₉₀ level: concentration that inhibits parasite growth by 90%) for 12 h. Parasite proteins were separated by 2-dimensional electrophoresis and identified by LC/MS/MS.ResultsAt the IC₅₀ concentration, about 82% of the expressed parasite proteins were matched with the control (non-exposed), while at the IC₉₀ concentration, only 15% matched proteins were found. The selected protein spots from parasite exposed to the plant extract at the concentration of 12 μg/mL were identified as enzymes that play role in glycolysis pathway, i.e., phosphoglycerate mutase putative, L-lactate dehydrogenase/glyceraldehyde-3-phosphate dehydrogenase, and fructose-bisphosphate aldolase/phosphoglycerate kinase. The proteosome was found in parasite exposed to 30 μg/mL of the extract.ConclusionsResults suggest that proteins involved in the glycolysis pathway may be the targets for antimalarial activity of G. mangostana Linn. (pericarp).

Incidence and Associated Factors for Single and Recurrent Falls among the Elderly in an Urban Community of Beijing

Objective To investigate the incidence of falls and recurrent falls, and explore associated factors for single and recurrent falls among urban community-dwelling elderly in Beijing. Methods A cross-sectional study was conducted in 472 elderly in the Longtan community of Dongcheng district, Beijing in 2009. Data regarding the incidence of fall and recurrent falls in the previous year, as well as associated factors were collected from the elderly through face-to-face interviews. Results The incidence of falls and recurrent falls was 17.8% and 6.1%, respectively, and it increased with age(χ2for trend=21.06, 19.20, P=0.001, 0.002). Binary logistic stepwise regression analysis showed that age(OR=2.20), living alone(OR=4.67) and gait disturbance(OR=1.27) were risk factors, while housing with elevators(OR=0.35), appropriate width/height of stair steps(OR=0.78), sufficient lighting for stairway(OR=0.45) and regular exercise(OR=0.12) could lower the risk for single fall; factors such as low monthly family income(OR=1.39), poor vision(OR=1.83), low physical ability(OR=4.47), abnormal static balance(OR=2.48), and fear of falls(OR=2.23) were risk factors, while appropriate width/height of stair steps(OR=0.49) and easiness of access to daily supplies(OR=0.41) were protective factors for recurrent falls. Conclusion The incidence of falls in community-dwelling elderly people in Beijing is common, and falls and their related injuries have been associated with both intrinsic and extrinsic factors.

The effect of alphastatin peptide suppressing the hypoxia-induced vasculogenic mimicry formation of glioma

Objective： To investigate the vasculogenic mimicry formation induced by hypoxia in Ⅱ-Ⅲ human glioma cell and the effect of alphastatin peptide suppressing the hypoxia-induced vasculogenic mimicry formation and the mechanism. Methods： MTT, Transwell and three- dimentional culture were used to detect the proliferation, migration and tubule formation of SHG44. The expression of vascular endothelial growth factor-α（VEGF-α, erythropoietin-producing hepatocellular carcinoma-A2 （EphA2） and matrix metalloproteinases 2 （MMP2） was detected by RT-PCR and Western blotting analysis. Results： The OD490 in hypoxia group was 0.60±0.06 and in control group was 0.46±0.05. The number of cell migration was 178.71±18.81 in hypoxia group and 85.86±17.92 in control group. The tubule formation was 56.80±12.21 in hypoxia group and 4.20±2.62 in control group. The proliferation, migration and tubule formation in hypoxia group were significantly higher than that in control group. The expression of VEGF-α, EphA2 and MMP2 was upregulated in hypoxia. When various concentrations of alphastatin （100, 1 000, 10 000 nmol/L） were added to hypoxia group, the numbers of cell migration were 142.57±12.12, 92.71±17.68, 30.00±7.72 and the tubule formation were 47.71±10.58, 18.86±8.40, 8.43±5.62. The cell migration and tubule formation were significantly suppressed by alphastatin in a dose-dependent manner. In alphastatin group, the phosphorylation of EphA2 protein （P=0.037, F=4,629） and activation of MMP2 protein （P=0.005, F=9.331） were significantly suppressed but there was no change in VEGF-α protein. Conclusion： Ⅱ-Ⅲ human glioma cell is able to form vasculogenic mimicry induced by hypoxia and alphastatin peptide can suppress the hypoxia-induced vasculogenic mimicry. VEGF-α induced EphA2 phospharilation and MMP2 activation maybe the key pathway to form vasculogenic mimicry.
