Oxidative stress is involved in the pathogenesis of periodontitis. A reduction of oxidative stress by drinking hydrogen-rich water (HW) might be beneficial to periodontal health. In this pilot study, we compared the effects of non-surgical periodontal treatment with or without drinking HW on periodontitis. Thirteen patients (3 women, 10 men) with periodontitis were divided into two groups: The ...

This paper defines, for each convex polytope ∆, a family Hw∆ of vector spaces. The definition uses a combination of linear algebra and combinatorics. When what is called exact calculation holds, the dimension hw∆ of Hw∆ is a linear function of the flag vector f∆. It is expected that the Hw∆ are examples, for toric varieties, of the new topological invariants introduced by the author in Local-gl...

BACKGROUND Because twigs of Cinnamomum cassia (TC) have been reported to exert anti-cancer activity, the mechanistic study for TC's anti-cancer activity is required. Thus, we elucidated the potential molecular mechanism of TC's anti-proliferative effect and the induction of apoptosis in human colorectal cancer cells. METHODS How water extracts form TC (TC-HW) was used in this study. Anti-cell...

The suppressor of Hairy-wing [su(Hw)] protein represses enhancer function in a unidirectional fashion: enhancers segregated from the promoter by the su(Hw) binding region are rendered inactive. whereas those in the same domain are unaffected. In the case of the gypsy-induced y2 allele, the repressive effect of su(Hw) is rendered bidirectional in mod(mdg4) mutant flies, and all enhancers of the ...

Mutations induced by the gypsy retrotransposon in the forked (f) and cut (ct) loci render their expression under the control of the suppressor of Hairy-wing [su(Hw)] gene. This action is usually recessive, but su(Hw) acts as a dominant on the alleles fk, ctk and ctMRpN30. Molecular analysis of the gypsy element present in fk indicates that this allele is caused by the insertion of a modified gy...

When the classical chi(2) goodness-of-fit test for Hardy-Weinberg (HW) equilibrium is used on samples with related individuals, the type I error can be greatly inflated. In particular the test is inappropriate in population isolates where the individuals are related through multiple lines of descent. In this article, we propose a new test for HW (the QL-HW test) suitable for any sample with rel...

Hydrogen-rich electrolyzed warm water (HW) was prepared at 41°C and exhibited dissolved hydrogen (DH) of 1.13 ppm and an oxidation-reduction potential (ORP) of -741 mV in contrast to below 0.01 ppm and+184 mV for regular warm water (RW). Fibroblasts OUMS-36 and keratinocytes HaCaT were used to examine effects of HW against UVA-ray irradiation. Type-I collagen was synthesized 1.85- to 2.03-fold ...

3 SUMMARY When the classical χ 2 goodness-of-fit test for Hardy-Weinberg (HW) equilibrium is used on samples with related individuals, the type I error can be greatly inflated. In particular the test is inappropriate in population isolates where the individuals are related through multiple lines of descent. In this paper, we propose a new test for HW (the QL-HW test) suitable for any sample wit...

HW/SW interfaces allow verification early in the design process. Verification of the HW/SW interface itself imposes new challenges. It is not sufficient to verify the interface independent of its context—the interface must be verified relative to a given hardware platform. Of course, researchers can’t wait until the hardware prototype is available to carry out this verification. Researchers can...

PURPOSE To evaluate the accuracy of ultrasound (ULTRA) in assessing fat-free mass (FFM) in comparison with hydrostatic weighing (HW) and skinfolds (SK) in high school wrestlers in a hydrated state. METHODS Body composition was determined by ULTRA, HW, and three-site SK in 70 high school wrestlers (mean +/- SD: age, 15.5 +/- 1.5; height, 1.60 +/- 0.08 m; body mass, 65.8 +/- 12.7 kg). For all m...
