Effects of finger tapping frequency on regional homogeneity of sensorimotor cortex. [PDF]

open access: yesPLoS ONE, 2013
Resting-state functional magnetic resonance imaging (RS-fMRI) has been widely used to investigate temporally correlated fluctuations between distributed brain areas, as well as to characterize local synchronization of low frequency (

Altered regional homogeneity in the development of minimal hepatic encephalopathy: a resting-state functional MRI study. [PDF]

open access: yesPLoS ONE, 2012
BACKGROUND: Little is known about how spontaneous brain activity progresses from non-hepatic encephalopathy (non-HE) to minimal HE (MHE). The purpose of this study was to evaluate the evolution pattern of spontaneous brain activities in cirrhotic ...

Ensuring homogeneity of regional socio-economic development: Republic of Bashkortostan case study

open access: yesВестник университета, 2023
Over the past several years, an increase in regions’ heterogeneity determined by the uneven distribution of resources, lack of effective levers of innovation management, and the growing shortage of financial resources has become one of the main features ...

Analysis of Cross-Border Regional Homogeneity and Its Effects on Regional Resilience and Competitiveness

open access: yesActa Universitatis Sapientiae: Economics and Business, 2017
The resilience of a region may affect how it reacts to economic crises and exogenous shocks. In a complex study, it is not sufficient merely to have knowledge of all the macro-indices of the regions, but it is also necessary to study internal micro ...

Gravitational energy as dark energy: Average observational quantities [PDF]

open access: yes, 2009
In the timescape scenario cosmic acceleration is understand as an apparent effect, due to gravitational energy gradients that grow when spatial curvature gradients become significant with the nonlinear growth of cosmic structure.

Regional homogeneity approach to fMRI data analysis

open access: yesNeuroImage, 2004
Kendall's coefficient concordance (KCC) can measure the similarity of a number of time series. It has been used for purifying a given cluster in functional MRI (fMRI). In the present study, a new method was developed based on the regional homogeneity (ReHo), in which KCC was used to measure the similarity of the time series of a given voxel to those of

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated
