Purpose: Reticular pseudodrusen (RPD) are considered to be a distinct feature in AMD. Population studies have studied the epidemiology of RPD using standard color fundus photographs (CFP). However, recent studies have shown that RPD are better imaged using near-infrared (NIR) imaging. We studied the epidemiology of RPD in a large population-based study using NIR and CFP. Methods: Participants aged 65+ years from the Rotterdam Study underwent ophthalmologic examination including NIR and CFP...

BACKGROUND: Prior studies have noted gender differences in cognition, imaging, and pathological markers in mild cognitive impairment (MCI) subjects. Sex hormone-binding globulin (SHBG), a major controlling factor in the proportion of bioavailable versus bound testosterone and estrogen, has been proposed to contribute to links between hormones and dementia, but has not yet been investigated fully in a prospective biomarker trial. OBJECTIVE: This study examined whether, among subjects with MCI, SHBG levels predict future rate of cognitive decline...

Combining NMR spectroscopy, transmission electron microscopy, biochemical and in vitro toxicity assays, we characterized the effect of flavonoid glycosylation, a chemical modification very frequent in Nature, on their ability to recognise and bind Aβ1-42 oligomers, preventing their aggregation and their neurotoxicity. Our data allow the elucidation of their structure activity relationships, showing that glycosylation has a modest impact on flavonoid affinity for Aβ oligomers but, at the same time, increases both solubility and chemical stability, thus promoting their beneficial properties against Alzheimer's diseases (AD)...

We propose a geodesic distance on a Grassmannian manifold that can be used to quantify the shape progression patterns of the bilateral hippocampi, amygdalas, and lateral ventricles in healthy control (HC), mild cognitive impairment (MCI), and Alzheimer's disease (AD). Longitudinal magnetic resonance imaging (MRI) scans of 754 subjects (3092 scans in total) were used in this study. Longitudinally, the geodesic distance was found to be proportional to the elapsed time separating the two scans in question. Cross-sectionally, utilizing a linear mixed-effects statistical model, we found that each structure's annualized rate of change in the geodesic distance followed the order of AD > MCI > HC, with statistical significance being reached in every case...

BACKGROUND: Results from a phase 2a study indicated that treatment with the novel α7 nicotinic acetylcholine receptor agonist ABT-126 25 mg once daily (QD) was associated with a trend for improvement in cognition in subjects with mild-to-moderate Alzheimer's dementia (AD). A phase 2b program was designed to evaluate a broader dose range of ABT-126 as monotherapy in subjects with mild-to-moderate AD. The program consisted of a double-blind, placebo and active controlled study of ABT-126 (dose range 25-75 mg) and an open-label extension study (75 mg)...

Many hypertension guidelines have been published mainly from Western countries to standardize the management of hypertension all over the world, however, the significance of hypertension, along with other cardio-metabolic risks, such as obesity, diabetes or dyslipidemia should differ among different races. This paper compares the relevance of hypertension, one of the most important cardio-metabolic risk factors, in Asian and Western societies.1) Low target level of blood pressure control for diabetic hypertensives in JapanIn the Japanese Society of Hypertension Guidelines for the management of Hypertension (JSH2014), the target of blood pressure (BP) control in hypertensive patients with diabetes was set as < 130/80 mmHg...

OBJECTIVE: Flow mediated dilation (FMD) is the most physiological relevant form of endothelial-mediated vasodilation. Our laboratory has previously shown that telomerase, a ribo-nucleoprotein that counteracts telomere shortening, has a protective effect on endothelial function under conditions of oxidative stress in the human microcirculation. In the presence of coronary artery disease, decreased telomerase activity contributes to a shift in the mediator of FMD from atheroprotective nitric oxide (NO) to pro-inflammatory and atherogenic hydrogen peroxide (H2O2)...
