The palladium films’ resistance initially decreases after a first exposure to 5 Torr of hydrogen, and this is tentatively explained by the reaction of hydrogen with impurities trapped in the films.”
“An extract of Lentinula edodes mycelia (L.E.M.) was obtained with hot water after culturing in medium comprising bagasse and rice bran. It has been reported that L.E.M. exhibits

physiological effects such as anticancer activity and immunoregulatory activity, and that such effects involve macrophage activation. We examined the active components in L.E.M. by fractionation using an anion exchange carrier and gel chromatography, and determined whether they stimulate production of the cytokine tumor necrosis factor-alpha (TNF-alpha) in RAW264.7 cells. We obtained 2 polysaccharide

fractions, IA-a and IA-b, which potently stimulated cytokine production. We also confirmed that IA-a and HM781-36B nmr IA-b significantly stimulate phagocytosis in RAW264.7 cells. To determine the structures of these fractions, we performed sugar component analysis, methylation analysis, FT-IR, (13)C-NMR analysis, and molecular weight analysis. The results showed that the major component of IA-a is a 1,4-alpha-glucan exhibiting 1,6-branching and having a molecular weight of approximately 250,000. This branching structure suggests that IA-a has a glycogen-like structure. In addition, the major component of IA-b appears to be an arabinoxylan-like polysaccharide, LY2606368 concentration mainly consisting of arabinose and xylose, with a molecular weight of approximately 8,500.”
“We have analysed the reasons for the low reported incidence of prostate cancer in China and argue for early diagnosis and treatment of this disease. According to

the 2002 database of the International Agency for Research on Cancer (IARC), the age-standardized CCI-779 cell line incidence of prostate cancer in China is 1.6/10(5) person years (PY), with a mortality rate of 1.0/10(5) PY and mortality-to-incidence rate ratio (MR/IR) = 0.63. The MR/IR ratio of prostate cancer in China was found to be higher than the average in Asia (MR/IR = 0.57) and much higher than that in North America (MR/IR = 0.13). These data indicate that in China most prostate cancers were in the advanced stages at the time of diagnosis, and that patients had a short survival time thereafter. In 2004, Stamey et al. reported a retrospective American study of prostate cancer for the years 1983-2003. It was shown that most cases of prostate cancer detected by prostate-specific antigen (PSA) screening were in the advanced stage at the start of this 20-year period. These early follow-up data are quite similar to the results obtained from mass PSA screening of elderly men in Changchun, China. However, after the American programmes for early diagnosis and treatment of prostate cancer were accepted, tumours were diagnosed at earlier stages.
