Dexmedetomidine Stereotaxic Injection Alleviates Neuronal Loss Following Bilateral Common Carotid Artery Occlusion Up-Regulation of BDNF Expression.

Background/aim: Neurogenesis is an important process in the recovery from neurological damage caused by ischemic lesions. Endogenous neurogenesis is insufficient to restore neuronal damage following cerebral ischemia. Dexmedetomidine (DEX) exerts neuroprotective effects against cerebral ischemia and ischemia/reperfusion injury.

Microbiome Changes in Layer Pullets Reared in Floor Pens along the Growth Period.

The gastrointestinal tract microbiome is essential for regulating nutrient absorption, gut immune function, and host growth and development. In the present study, we characterized the development of ileum and cecum microbiota in pullets throughout the rearing period, encompassing a period from the day of hatching to 18 weeks of age. The growth performance and intestinal microbiome (ileum and cecum) of pullets were analyzed at 1, 5, 11, and 18 weeks of age.

Differential Expression of Pax6 Following Bilateral Common Carotid Artery Occlusion.

Background/aim: Chronic cerebral hypoperfusion causes neuronal damage involving cognitive impairment and development of dementia. Permanent bilateral common carotid artery occlusion (BCCAO) in rat models is used to study chronic cerebral hypoperfusion. Pax6 is used as an early neurogenesis marker which affects the maturation of neuronal cells.

Differential Expression of BDNF and BIM in Streptozotocin-induced Diabetic Rat Retina After Fluoxetine Injection.

Background: Chronic diabetic retinopathy (DR) is a diabetic complication that causes blindness. Brain-derived neurotrophic factor (BDNF) expression is induced by fluoxetine. We observed the effects of fluoxetine on a streptozotocin (STZ)-induced diabetic rat model in this study.

IGF-1 Protects Neurons in the Cortex and Subventricular Zone in a Periventricular Leucomalacia Model.

Background/aim: Chronic cerebral hypoperfusion affects early and mature neurons in the subventricular zone (SVZ) and cerebral cortex. Herein, we investigated the effects of insulin-like growth factor-1 (IGF-1), a neurogenesis-promoting agent, on neurons in these regions in periventricular leucomalacia (PVL) model rats.

Materials And Methods: Following right carotid artery ligation, the rats were placed in a hypoxia chamber and injected with recombinant IGF-1 (0.

Differential Expression of Vascular Endothelial Growth Factor in the Cortex and Hippocampus upon Cerebral Hypoperfusion.

Background/aim: Vascular endothelial growth factor (VEGF) provides tolerance against ischemic brain injury, yet, the pattern of VEGF expression in the neurogenic zones following chronic cerebral hypoperfusion has not been studied. Here we evaluated the immunoreactivity of VEGF in a rat model of chronic cerebral hypoperfusion.

Materials And Methods: Chronic hypoperfusion was induced by bilateral common carotid artery ligation in rats.

Up-regulation of Rhoa/Rho kinase pathway by translationally controlled tumor protein in vascular smooth muscle cells.

Translationally controlled tumor protein (TCTP), a repressor for Na,K-ATPase has been implicated in the development of systemic hypertension, as proved by TCTP-over-expressing transgenic (TCTP-TG) mice. Aorta of TCTP-TG exhibited hypercontractile response compared to that of non-transgenic mice (NTG) suggesting dys-regulation of signaling pathways involved in the vascular contractility by TCTP. Because dys-regulation of RhoA/Rho kinase pathway is implicated in increased vascular contractility, we examined whether TCTP induces alterations in RhoA pathway in vascular smooth muscle cells (VSMCs).

Characterization of polyacrylonitrile based carbon nanofiber mats via electron beam processing.

The aim of this study was to evaluate the ability of electron beam irradiation to drive stabilization reactions within PAN nanofiber mats to obtain carbon nanofiber mats. PAN nanofiber mats with fiber diameters of 300-400 nm were prepared via an electrospinning method. Electrospun PAN nanofiber mats were stabilized by electron beam irradiation with various doses up to 5,000 kGy.

Test-retest reliability of the functional mobility assessment (FMA): a pilot study.

Purpose: Functional mobility is necessary to perform activities of daily living and for community participation for everyone, but especially important for persons with disabilities (PWD). Therefore, functional mobility requires reliable measurement of consumer satisfaction and functional changes. The functional mobility assessment (FMA) instrument is a self-report outcomes tool designed to measure effectiveness of wheeled mobility and seating (WMS) interventions for PWD.

Hypertension resulting from overexpression of translationally controlled tumor protein increases the severity of atherosclerosis in apolipoprotein E knock-out mice.

Hypertension is a well-established etiological factor for atherogenesis. We previously showed that transgenic mice overexpressing translationally controlled tumor protein (TCTP) develop systemic arterial hypertension. In this study we explored the cardiovascular effects of TCTP overexpression and possibly of the resultant hypertension on the severity of atherosclerosis in apolipoprotein E-deficient mice.
