Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

Variability studies in Okra (Abelmoschus esculentus L. Moench)

Electronic Journal of Plant Breeding, 2016
Sixty genotypes of okra were evaluated in one location for two years at Chatha, Jammu during 2009-10 and 2010-11. The objective was to study the genetic variability between various economically important traits for the purpose of genetic improvement. The

Accelerated Progression of Gait Impairment in Parkinson's Disease and REM Sleep Without Atonia

Annals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective People with Parkinson's disease (PD) and rapid eye movement (REM) sleep without atonia (RSWA) often have more severe gait disturbances compared to PD without RSWA. The association between the presence and expression of RSWA and the rate of progression of gait impairment in PD is unknown.

Measuring Plant Genetic Diversity Using Inter-Simple Sequence Repeats (ISSRS) [PDF]

, 2007
Simple sequence repeats (SSRs) have great utility as they are conserved and present in all eukaryotic genomes. Here we report the use of a simple PCR with fluorescently-labelled primers to amplify inter-SSR markers (ISSRs) for diversity assessments.
