Characteristics of monolayer behavior and multilayer film structures of comb polymers having different kinds of fluorocarbon side-chains.

With comb polymers with different kinds of fluorocarbon side-chains, significant effects of spreading solvents on the monolayers at the air/water interface and the molecular arrangement in the deposited films could be found by the use of trifluoroacetic acid and its mixed solvents with n-hexane, depending on the atoms, fluorine or hydrogen, substituted at the end of the fluorocarbon side-chains. These facts are probably due to intralayer hydrogen bonding cooperating with the carbonyl groups of the long-chain esters. The deposited films of solid substrates were characterized by polarized near-edge X-ray absorption fine structure (NEXAFS) spectroscopy as well as in-plane X-ray diffraction and scanning electron and atomic force microscopy.

Association between birth weight and serum lipid concentration in premenopausal Japanese women.

BACKGROUND: The relationships between birth weight and serum lipid concentrations in pre-menopausal Japanese women were not well identified and also diet and serum hormone status in these women would be considered. METHODS: A total of 59 premenopausal Japanese women completed a self-administered questionnaire including basic demographic information, disease histories, and menstrual and reproductive histories. They were asked to obtain information on birth weight recorded in mother-and-baby notebook issued by municipality from their mother. Diet was assessed by daily diet records from day 2 through day 10 of the menstrual cycle. Blood sample was collected on day 11 of the cycle to measure serum lipid and hormone concentrations (total and high-density lipoprotein [HDL] cholesterols, triglyceride, estrone, estradiol, and sex hormone-binding globulin). RESULTS: Birth weight was significantly correlated with HDL cholesterol (r = 0.32, p = 0.03), but not with total cholesterol and triglyceride after controlling for age. Neither estrogen nor sex hormone-binding globulin was significantly correlated with serum lipid concentrations after controlling for age and the number of days prior to the next menses. The correlation between birth weight and HDL cholesterol was not affected after additional adjustment for serum estrogen and intakes of protein, calcium, and iron. CONCLUSION: These data suggest that intrauterine growth may be associated with lipid profile.

[Retinal thickness and changes with age].

PURPOSE: We studied the morphological changes occurring with aging in the macula using optical coherence tomography(OCT). METHODS: Forty-seven eyes from 47 normal volunteers were studied. The subjects ranged in age from 21 to 79 years and their refractive errors were within +/- 3.00 diopters. The measurement of the retinal thickness was done by OCT. The retinal thickness was evaluated at five points: the foveola, and 1 mm superior, inferior, nasal, and temporal to the foveola. The axial length of the eye and the refraction were also measured in all subjects. RESULTS: The retinal thickness was 142 +/- 15 microns at the foveola, 257 +/- 18 microns at the superior point, 255 +/- 18 microns at the inferior point, 246 +/- 20 microns at the temporal point, and 261 +/- 21 microns at the nasal point (mean +/- standard deviation). All points except the foveola showed reduced retinal thickness with age. Thus, attenuation of the retinal thickness in the parafoveal area was correlated significantly with age. However, no change in the retinal thickness at the foveola was observed with increasing age. Neither axial length nor refractive error biased this result. CONCLUSION: Our results demonstrated that the macular thickness changes with aging, but no obvious change could be detected in the foveola.
