    Interactions of Divalent Cations in Their Action on ATPases from Cucumber Roots (1979)

    Notes: A microsomal fraction (10,000–30.000 g) was prepared from roots of Cucumis satirus L. (cv. Bestseller Fl) grown in solution culture. The ATPase activity was stimulated by Mg and Mn with optima between pH 6 and 7. Stimulation by Ca was obtained only above pH 7. Activations by Mg and Mn were inhibited by Ca, Mn and Mg interacted, so that Mn appeared strongly inhibitory for activation by Mg and Mg weakly inhibitory for activation by Mn: the simplest interpretation for this would be two separate enzymes. Cucumber accumulates and deposits Ca contrary to wheat and oat, which contain Ca-activated ATPase in the pH region 6 to 7. The Ca data for cucumber are compared with earlier findings from wheat and oat and are tentatively related to known physiological differences.

    Notes: Summary Circadian variations of plasma renin activity, plasma dopamine-beta-hydroxylase, and urinary aldosterone excretion were measured in man under conditions of high- and low-sodium intake. Plasma renin activity and urinary aldosterone excretion were maximal at 8 a.m. Plasma DBH shows small, biologically insignificant circadian fluctuations. In three subjects on low-salt diets, the values were lower than those in the same subjects on high-salt diets. Expansion of intravascular volume in supine normal volunteers lowered plasma renin and DBH activity, and also resulted in a significant natriuresis. The decline in DBH activity probably reflects a decrease in its release from autonomic nerve endings and thus demonstrates in man an effect of decreasing autonomic activity.

    Notes: Abstract In this present study, four hemodialyzed patients with cervical myelopathy treated by canal-expansive laminoplasty are reported. The average duration of hemodialysis was 18 years, and the average follow-up was 16 months. Early results show maintenance of sagittal alignment and reduction of instability of the cervical spine with no progression of the destructive spondyloarthritis.

    Tumor necrosis factor-α in peripheral nerve lesions (1997)

    Notes: Abstract Immunocytochemical expression of tumor necrosis factor-α (TNF-α) was examined in nerve biopsy samples of patients with various disorders, focusing on nerve injury. TNF-α was mainly associated with phagocytosing macrophages in acute axonal injury, but the staining was more frequently seen in sections from patients with vasculitis than with metabolic neuropathy. Ramified macrophages outside nerve fibers were also positive for TNF-α in the acute stage of vasculitis. In active demyelinating lesions from patients with chronic inflammatory demyelinating neuropathy (CIDP), macrophages outside nerve fibers showed weak staining with TNF-α, but the cells adhering to myelinated nerve fibers showed definite staining. This may be due, in part, to the smouldering course of CIDP, and expression may be up-regulated transiently during the demyelinating process. These results indicate that macrophages, as the effector cells for both axonal injury and active demyelination, express TNF-α, but their activation mechanisms may vary among vasculitis, metabolic axonopathy and inflammatory demyelination.

    Circadian variation in urinary melatonin in clinically healthy women in Japan and the United States of America (1979)
    Springer
    Cellular and molecular life sciences 35 (1979), S. 416-419

    Notes: Summary Urinary melatonin excretion is lower in East-Asian (Japanese) than in North-American (whites of mixed ethnic origin) women. Moreover, a statistically significant circadian rhythm is demonstrated by population-mean cosinor in the data pool from both groups of women. Furthermore, statistical significance characterizes interactions of effects from geographic differences (between ethnic groups) with temporal factors. Such spatio-temporal interactions await further scrutiny with a view inter alia of carcinogenesis as it is influenced by a spectrum of intermodulating rhythms.

    High-dose (9 MU) long-term (60 weeks) alfa-interferon therapy for chronic hepatitis patients infected with HCV genotype 1b (1998)
    Springer

    Notes: Summary.  Efficacy of standard regimens (e.g., 3–6 MU for 24 weeks) of alfa-IFN therapy for chronic hepatitis C has been limited, particularly in patients with HCV/1b. To see if higher-dose longer term treatment is more effective, we tried a 9 MU 60-week regimen. HCV/1b-infected chronic hepatitis patients received 9 MU IFNα2a everyday but Sunday for 2 weeks and thrice a week for next 10 weeks, and 76 patients became HCV RNA-negative while 81 remained positive. The RNA-negative patients were then randomized to receive 3 MU (group I, n=37) or 9 MU (group II, n=39) for 48 weeks. Of the RNA-positive patients, only those with normal ALT received another 9 MU 48-week treatment (group III, n=45). Sustained responders (SR) were defined as those with negative RNA and normal ALT 6 months after the therapy. SR rates based on intent-to-treat principle did not differ significantly between groups I and II (30% vs 41%), but those based on the protocol-compatible cases showed a significant difference (32% vs 56%, p=0.034). SR rate in group III was significantly lower than those in group II. Adverse effects of IFN, developed more frequently in groups II and III than in group I, were mostly reversible. In conclusion, our results encourage 9 MU 60-week IFNα treatment in HCV/1b-infected patients with careful attention to adverse effects, and suggest that the treatment should be discontinued if HCV RNA does not disappear within 12 weeks.

    Infrequent but significant p21/WAF1/CIP1 gene alteration in synchronous or metachronous transitional cell carcinoma (1996)

    Notes: Abstract p53 inducible cyclin dependent kinase inhibitor, p21/WAF1/CIP1(p21), played a pivotal role for G1 arrest when cells received genotoxic stimuli. p21 could be a putative tumor suppressor gene, since its dysfunction may lead to accumulation of genomic alteration. We investigated the p21 and p53 status using polymerase chain reaction-single strand conformation polymorphism (PCR-SSCP) and immunohistochemical analyses, in eight patients who had synchronous or metachronous urothelial tumors. Loss of heterozygosity (LOH) of p21 gene was detected in one coincidental tumor in one case. p21 positive cells were detected by immuno-histochemical staining in all tumors in one case, and in one coincidental tumor in two cases. Among p21 positive cells in these three cases, no p53 mutations were detected, whereas no p21 positive cells were detected in other cases with a p53 mutation. These findings suggested that in transitional cell carcinoma (TCC) p21 gene mutation is infrequent like the p53 gene mutation, but that LOH might be important in the inactivation of p21.

    Notes: Abstract Genotoxic stimuli, including anticancer drugs, induce apoptosis in cancer cells through increase of p53, p21WAF1/CIP1 , at least in part. Bcl-2 and Bax modify this pathway or directly regulated by p53. Here we studied Adriamycin (ADM)-induced apoptosis in four human bladder cancer cell lines in respect of p53, p21WAF1/CIP1 and Bcl-2 family proteins. After ADM, treatment bladder cancer cells underwent dose-dependent cell death with typical morphologic features of apoptosis. Among four cell lines RT4 with wt p53, low ratio of Bcl-2 to Bax and induction of p21WAF1/CIP1 after ADM treatment, was the most sensitive to induction of apoptosis. Thus, p53, p21WAF1/CIP1 , Bcl-2 and Bax status might determine susceptibility of bladder cancer cells to ADM induced apoptosis.

    Notes: The electron impact mass spectra of twenty acetates and methylates of spirostanol and related furostanol glycosides of high molecular weight (above 650) have been investigated, and the most probable fragmentation patterns of the glycoside derivatives are presented. High resolution mass spectrometry provides useful information concerning the structures of both aglycone and sugar moieties as well as the molecular size of the oligoglycosides.
