    Serum lipoprotein(a) concentrations and apolipoprotein(a) phenotypes in the families of NIDDM patients (1995)

    Notes: Summary We studied the quantitative and qualitative characteristics of lipoprotein(a) [Lp(a)] as a function of apolipoprotein(a) [apo(a)] phenotype in 87 members (42 males, 45 females) of 20 diabetic families, 26 of whom were diagnosed with non-insulin-dependent diabetes mellitus (NIDDM) with moderate glycaemic control (HbA1c7.1±1.2%). Apo(a) phenotyping was performed by a sensitive, high-resolution technique using SDS-agarose/gradient PAGE (3–6%). To date, 26 different apo(a) phenotypes, including a null type, have been identified. Serum Lp(a) levels of NIDDM patients and non-diabetic members of the same family who had the same apo(a) phenotypes were compared, while case control subjects were chosen from high-Lp(a) non-diabetic and low-Lp(a) non-diabetic groups with the same apo(a) phenotypes in the same family. Serum Lp(a) levels were significantly higher in NIDDM patients than in non-diabetic subjects (39.8±33.3 vs 22.3±19.5 mg/dl, p〈0.05). The difference in the mean Lp(a) level between the diabetic and non-diabetic groups was significantly (p〈0.05) greater than that between the high-Lp(a) non-diabetic and low-Lp(a) non-diabetic groups. An analysis of covariance and a least square means comparison indicated that the regression line between serum Lp(a) levels [log Lp(a)] and apo(a) phenotypes in the diabetic patient group was significantly (p〈0.01) elevated for each apo(a) phenotype, compared to the regression line of the control group. These data, together with our previous findings that serum Lp(a) levels are genetically controlled by apo(a) phenotypes, suggest that Lp(a) levels in diabetic patients are not regulated by smaller apo(a) isoforms, and that serum Lp(a) levels are greater in diabetic patients than in non-diabetic family members, even when they share the same apo(a) phenotypes.

    Notes: Abstract To clarify the mechanism of plasma nitriding, we examined the optical microstructure, the hardness, the precipitation, and the concentration of dissolved nitrogen in Fe-18Cr-9Ni nitrided using plasma in the range of 723–823 K. Compared with ammonia-gas nitriding, the features of plasma nitriding are the formation of small chromium-nitride precipitates (CrN), the absence of an externally nitrided layer, the high concentration of dissolved nitrogen, and the high hardness (HV=1200). The diffusion coefficient of nitrogen in the present alloy was determined using the growth rate of the internally nitrided layer, based on calculations used in internal oxidation. Plasma- and gas-nitriding were also compared with respect to the growth rate of the nitrided layer.

    The concepts, procedures, and problems related in endoscopic laser therapy of early gastric cancer (1989)
    Springer
    Surgical endoscopy and other interventional techniques 3 (1989), S. 1-6 
    Details
    ISSN: 1432-2218
    Keywords: Gastric carcinoma ; Endoscopy ; Laser therapy
    Source: Springer Online Journal Archives 1860-2000
    Topics: Medicine
    Notes: Summary We report 34 cases of early gastric cancer in which endoscopic laser therapy was performed at the Kitasato University Hospital. The problems encountered were the size and location of the tumor, the presence of lymphatic metastasis or concomitant disorders, and technical problems associated with the irradiation procedure. Of the 34 cases, 22 cases were considered as completely cured (no malignancy was detected after laser therapy), 11 cases were incompletely cured (malignant cells were detected after laser therapy), and 1 case was undetermined.
