The integrity of structural connectivity in a functional brain network supports the efficiency of neural processing within relevant brain regions. This study aimed to quantitatively investigate the short- and long-range fibers, and their differential roles in the lower cognitive efficiency in aging and dementia. Three groups of healthy young, healthy older adults and patients with Alzheimer's d...

OBJECTIVE To investigate peripheral blood lymphocyte subpopulations, particularly helper T (Th) cells and cytokine expression before and after treatment in polymyositis (PM) and dermatomyositis (DM). PATIENTS AND METHODS Ten patients with PM and 15 with DM were enrolled in this study. As a control we used 11 age-matched healthy subjects. We analyzed peripheral blood lymphocytes using flow cyt...

background: the aim of study was to measure particle matter concentration (pm 1, pm 2.5 and pm 10 ) during normal, semi-dust and dust-event days. the impacts of some meteorological factors on particle matter concentrations were also investigated. methods: samples were collected by grimm aerosol technik (gmbh model 1/108 germany) from november 2011 to may 2012. temperature, humidity, wind speed ...

background: air pollution has been a serious public health threat worldwide. it has been linked to pulmonary and cardiovascular diseases but is also believed to contribute to air-pollution-mediated cardiometabolic disease such as diabetes. we investigated the relationship between type 2 diabetes mellitus (dm2) and air pollution in densely developed urban settings in south korea, using national ...

Precision timing of millisecond pulsars in binary systems enables observers to detect the relativistic Shapiro delay induced by space time curvature. When favourably aligned, this constraints be placed on component masses and system orientation. Here we present results campaigns seven observed with 64-antenna MeerKAT radio telescope that show evidence delay: PSRs~J0101$-$6422, J1101$-$6424, J11...

The aim of this study was to measure the difference in the erosion depth of enamel measured by profilometry (PM) and a measuring microscope (MM). Sixty enamel specimens were divided into ten groups. Each specimen group was exposed to 50 ml of a carbonated drink with pH 2.38 or orange juice with pH 3.67 for 15, 30, 60, 120, and 180 minutes. Depths of eroded areas were measured with a profilomete...

[1] Ocean waves incident on coasts generate seismic surface waves in three frequency bands via three pathways: direct pressure on the seafloor (primary microseisms, PM), standing waves from interaction of incident and reflected waves (double-frequency microseisms, DF), and swell-transformed infragravity wave interactions (the Earth’s seismic hum). Beamforming of USArray seismic data shows that ...
