The 8-hydroxyquinolin-1-ium 2,2,2-trifluoroacetate and 8-hydroxyquinolin-1-ium 2,2,2-trichloroacetate (8-HQ) salts have been synthesized and characterized by FTIR, NMR and UV-Vis absorption spectroscopic methods. The third order nonlinear optical properties (NLO) of the two 8-HQ salts have been investigated by z-scan technique. The recorded experimental data led to calculate the nonlinear optical absorption coefficient (β), the nonlinear refractive index (n2), the excited-state absorption cross section (σex) and the ground-state absorption cross section (σg) of the studied compounds...

OBJECTIVE: Serum immunoglobulin (Ig) G4 elevation has been associated with several pathological conditions other than IgG4-related disease (IgG4-RD). In cystic fibrosis (CF), an elevation of specific IgG4 has been associated with colonization and infection by Pseudomonas aeruginosa. IgG4 elevation may be a marker of chronic infection or inflammatory stimulation. The aim of this study was to explore the prevalence of elevated IgG4 levels in CF and its correlation with the major clinical and microbiological features found in CF patients...

BACKGROUND AND PURPOSE: The Maximum Step Length Test (MSLT), a measure of one's capacity to produce a large step, has been studied in older adults, but not in people with Parkinson disease (PD). We characterized performance and construct validity of the MSLT in PD. METHODS: Forty participants (mean age: 65.12 ± 8.20 years; 45% female) with idiopathic PD completed the MSLT while "OFF" and "ON" anti-PD medication. Construct validity was investigated by examining relationships between MSLT and measures of motor performance...

BACKGROUND: Mindfulness (or "Mindful Attention") has been described as the presence or absence of attention to, and awareness of, what is occurring in the present moment. Among smokers, greater mindfulness is associated with greater effect stability and reduced cue-induced craving. While studies have shown that mindfulness is associated with other smoking-related factors such as reduced withdrawal symptoms using cross-sectional data, relatively little is known about the associations between baseline mindful attention and future abstinence-related effect/withdrawal...

The relationship between statins and cognition in Parkinson's disease (PD) is poorly understood. Analyses were performed to determine associations between statin use and cross-sectional and longitudinal cognitive performance in PD. Neuropsychological tests, medication logs, and ratings of functional abilities were collected from 313 PD participants longitudinally. At baseline, statin users (SU; N = 129) were older, more likely male, and had shorter PD duration than non-statin users (NSU; N = 184). In Cross-sectional analysis, SU performed better on global cognition, Trails B, semantic fluency, and phonemic fluency tasks...

BACKGROUND: It has been hypothesized that depression and obesity are bi-directionally associated, and when overweight people appear to show a lower risk of depression, this supports the "Jolly Fat" hypothesis. The aim of this study was to examine the "Jolly Fat" hypothesis in middle-aged women in Korea, by different perceived stress levels. METHODS: We performed a cross-sectional study of 44 to 56 aged Korean women (n = 2201) who underwent a health check-up program at the healthcare centers of Kangbuk Samsung Hospital (Seoul and Suwon centers) in Korea...

BACKGROUND: Metabolic syndrome (MetS) is associated with an increased risk of major cardiovascular events. Alanine aminotransferase (ALT) at high levels and total bilirubin (T-BiL) at low levels were oxidative potentials, but it was uncertain whether ALT and T-BiL had an additive interaction for the risk of MetS. METHODS: From a single community, we recruited 864 women (70 ± 8 years) during their annual health examination. We cross-sectionally investigated whether ALT and T-BiL are associated with MetS and its components based on the modified criteria of the National Cholesterol Education Program's Adult Treatment Panel (NCEP-ATP) III report...
