    Notes: Abstract Objectives: To clarify subsite-specific risk factors for hypopharyngeal and esophageal cancers (HC and EC), we concluded a hospital-based case–referent study in Nagoya, Japan. Methods: Subjects comprised 346 male cases with cancer of the hypopharynx (n = 62) or esophagus (upper [U-EC] 53, middle [M-EC] 159, lower [L-EC] 72), and 11,936 male referents free from cancer among first-visit outpatients aged 40–79 years in 1988–1997. Of histological confirmed cases, 93% comprised squamous cell carcinoma. Odds ratios (ORs) were estimated by a logistic regression model with adjustment for potential confounding factors. Results: Cigarette smoking increased the OR for M-EC, and alcohol drinking elevated the ORs for all subsites. The trend of ORs for combined cases of M- and L-EC tended to increase with number of cigarettes (p = 0.056), and a decreasing trend of the ORs was found with years after quitting smoking (p = 0.006). The ORs for smoking with drinking were multiplicatively greater than those for smoking or drinking in combined cases of HC and EC. In contrast, daily raw vegetable consumption lowered the ORs for all subsites. Conclusions: This study suggests that the magnitude of risk with smoking is stronger for M-EC within the esophagus, and drinking increases the risk at any subsite.

    Notes: Abstract Objectives: The purpose of this study was to examine the hypothesis that tea and coffee consumption have a protective effect against development of digestive tract cancers. Methods: A comparative case-referent study was conducted using Hospital-based Epidemiologic Research Program at Aichi Cancer Center (HERPACC) data from 1990 to 1995 in Nagoya, Japan. This study comprised 1,706 histologically diagnosed cases of digestive tract cancers (185 esophagus, 893 stomach, 362 colon, 266 rectum) and a total of 21,128 non-cancer outpatients aged 40 years and over. Logistic regression was used to analyze the data, adjusting for gender; age; year and season at hospital-visit; habitual smoking and alcohol drinking; regular physical exercise; fruit, rice, and beef intake; and beverage intake. Results: The odds ratio (OR) of stomach cancer decreased to 0.69 (95 percent confidence interval [CI] = 0.48-1.00) with high intake of green tea (seven cups or more per day). A decreased risk was also observed for rectal cancer with three cups or more daily intake of coffee (OR = 0.46, CI = 0.26-0.81). Conclusions: The results suggest the potential for protective effect against site-specific digestive tract cancer by consumption of green tea and coffee, although most associations are limited only to the upper category of intake and have no clear explanation for site-specificity.

    Notes: A model system for studying the reinforcement of paper is provided by the use of cationic latexes. The control of pH during addition of the latex to the pulp determines the uniformity of the latex deposition on the fibers. It is demonstrated, using scanning electron microscopy and mechanical testing of the sheet, that the dry and wet strength properties are improved by the more uniform distribution of a film-forming latex. Conversely, a nonfilming latex impedes bonding to the extent that the fiber surface is covered.

The effects of varying the methanol content and other process variables on the polymerization and on the properties of the latex are reported.

    Cationic latex interaction with pulp fibers. I. Deposition of styrene-butadiene latex having quaternized amino groups (1979)

    Notes: Four experimental latexes of different styrene-butadiene ratios stabilized with quaternized amino groups were employed in deposition studies on unbeaten kraft pulp fibers. The attraction between the oppositely charged latex and fibers facilitates a ready latex deposition in the pH region between the points of zero charge of the latex and of the fibers. The rate of deposition appears to be controlled by latex diffusion and convection up to the fiber surface. The distribution of latex particles deposited on the fiber surface is related to the butadiene content and the latex stability. Polystyrene latex is the most stable and covers the fibers uniformly as individual particles. With increased butadiene content, the coagulation region of the latex is more extended and the tendency to deposit as aggregates is promoted.

    Notes: Under equilibrium conditions the dependence of the electrical conductivity of cotton cellulose (Whatman 42 ashless filter paper) on moisture content was of an exponential type up to 3.5%. The transient conductivity of paper undergoing water sorption has been measured concurrently with the transient moisture content. The transient conductivity was greater than that at steady state, the difference increasing with decreasing initial moisture content. The results are explained in terms of thermal effects due to the heat evolved during water sorption.

    Notes: In the manufacture of corrugated board, thermal gelatinization of raw starch granules in the adhesive is essential for bonding setting. Kinetic studies of gelatinization of cornstarch adhesive under conditions simulating those at the corrugator revealed that the rate of advance of the gelatinization front in the starch film was linear with square root of time. A quasiactivation energy of 35.5 kJ/mol was found. The gelatinization process, above the gel point, was controlled by the rate of diffusion of water into the starch granules.

    Notes: A cell growth factor protein (insulin) and/or a cell-adhesion protein (fibronectin) were immobilized on surface-hydrolyzed poly(methyl methacrylate) membranes. The growth of mouse fibroblast cells STO was accelerated by the immobilized insulin. This acceleration was enhanced by introduction of spacer arms. Coimmobilization of insulin and fibronectin was very effective for the acceleration of cell growth. © 1993 John Wiley & Sons, Inc.

    Notes: Bone morphogenetic protein (BMP) is known to require a suitable carrier to induce ectopic bone formation in vivo. Hydroxyapatite ceramics have been reported to be effective in some forms but ineffective in others as a carrier of BMP-induced bone formation. In this study we compare three geometrically different forms of hydroxyapatite to examine their functions as carriers of BMP-induced bone formation. A fraction containing all the active BMPs (BMP cocktail) was partially purified from a 4M guanidine extract from bovine bone by a three-step chromatographic procedure. The BMP cocktail was combined with each of three forms of hydroxyapatite - solid particles (SPHAP), porous particles (PPHAP), and coral-replicated porous tablets (coral-HAP) - and implanted subcutaneously into rats. Both the PPHAP and coral-HAP systems induced osteogenesis 2 weeks after implantation, as evidenced by morphological and biochemical observations. Details of the osteogenetic process were followed by double-fluorescence labeling in the coral-HAP system to confirm bone formation on the surface of hydroxyapatite. However, there was no evidence of osteogenesis or chondrogenesis in the SPHAP system. The results indicate that the geometry of the interconnected porous structure in PPHAP and coral-HAP create spaces for vasculature that lead to osteogenesis while the smooth structure and close contact of particles in SPHAP inhibit vascular formation and proliferation of mesenchymal cells, preventing bone and cartilage formation. It was concluded that the geometrical structure in hydroxyapatite ceramics that induces vasculature is crucial as a carrier for BMP-induced bone formation. © 1998 John Wiley & Sons, Inc.
