Abstract

This case report describes the clinical efficacy of treatment with basic fibroblast growth factor (FGF-2) for periodontal regeneration. A patient with aggressive periodontitis participated in a clinical trial involving administration of 0.3% FGF-2 in comparison with a placebo control. To evaluate the efficacy of FGF-2, standardized radiographs were taken before surgery and at 12, 24, and 36 weeks after FGF-2 treatment. The rate of increase in alveolar bone height was 86.9% at 36 weeks. The 6-year postoperative radiograph showed significant development of alveolar bone in comparison with the first visit. FGF-2 treatment may be effective for periodontal regeneration in cases of aggressive periodontitis. (J Oral Sci 58, 137-140, 2016). [ABSTRACT FROM AUTHOR]

Abstract

Electrical properties of Hg1-xCdxTe layers grown by low-temperature metalorganic vapor phase epitaxy at 275°C have been studied. Substrates used were (100) GaAs. The precursors used were dimethylcadmium (DMCd), elemental mercury, and ditertiarybutyltelluride. Cadmium composition xof the layers was controlled from 0 to 1 by DMCd flow. Van der Pauw measurements were carried out in the temperature range from 25 to 300 K. For HgTe layers, typical 80 K electron concentration and Hall mobility of 4.4× 1016cm-3and 8.0× 104cm2/V·s were obtained. For CdTe, 300 K hole concentration and hole Hall mobility of 1.2× 1015cm-3and 6.5× 101cm2/V·s were obtained. In the intermediate Cd composition region of x=0.44, 80 K electron concentration of 8.0× 1015cm-3and Hall mobility as high as 7.4× 103cm2/V·s were also obtained. The experimental mobilities were explained by polar-optical phonon and alloy scattering.

Abstract

Background: The East Asian-specific genetic diversity, the rs671 variant of aldehyde dehydrogenase 2, causes the "Asian flush" phenomenon following alcohol consumption, resulting in an alcohol avoidance phenotype. The variant is suggested as a risk factor for Alzheimer's disease; however, its association with mild cognitive impairment (MCI), an effective target for secondary prevention of dementia, remains unclear., Method: This cross-sectional study examined 430 individuals aged 60-80 years (251 women) without overt cognitive impairment in Yoshinogari, Japan. The effect of the rs671 variant on MCI, defined by scores <26 or <25 on the Japanese version of the Montreal Cognitive Assessment, was evaluated using multivariate logistic regression., Results: The models included APOEε4, sex, age, education, history of habitual drinking, Brinkman index, hypertension, diabetes, and subclinical magnetic resonance imaging findings and consistently estimated the risk of the rs671 variant. Subsequently, stratified analyses by history of habitual drinking were performed based on an interactive effect between rs671 and alcohol consumption, and the rs671 variant significantly influenced MCI in participants who did not drink habitually, with odds ratios ranging from 1.9 to 2.1 before and after adjusting for covariates, suggesting an association independent of hippocampal atrophy and small vessel dysfunction. Conversely, no such association with the rs671 variant was observed in participants with a history of habitual alcohol use. Instead, hippocampal atrophy and silent infarcts were associated with MCI., Conclusions: This is the first study to demonstrate an association between the rs671 variant and MCI morbidity. The findings highlight the need for race-specific preventive strategies and suggest potential unrecognized mechanisms in dementia development.
