Effects of Neurotrophic Factors in Glial Cells in the Central Nervous System: Expression and Properties in Neurodegeneration and Injury
Conclusion and Future Aspects This review summarizes available NTF expression data, compiles existing evidence on the effects of glial NTF signaling in healthy conditions and in disease models (Figure 1), and highlights the importance of this topic for future studies. The relationship between NTFs and glia is crucial for both the developing and adult brain. While some of these factors, such as NT-3 and CNTF, have highly potent effects on gliogenesis, others like BDNF and GDNF, are important for glia-mediated synapse formation. Neurotrophic factors play significant roles during neurodegenerative disorders. In many cases, ...

Role of TREK-1 in Health and Disease, Focus on the Central Nervous System
Conclusion and Perspectives Since their cloning 20 years ago, the physiological importance of TREK-1 channels has continued to grow (Figure 3). Today, TREK-1 channels have been shown to be important and their presence is essential in a number of physiopathological processes. Their involvement in these different processes demonstrate the necessity to design pharmacological modulators, activators or inhibitors, of these channels to correct any TREK-1-related dysfunctions. Despites a number of studies and many molecule screenings, only few putative new drugs were identified. The activators belonging to the ML and BL series ...

Regulatory Genetic Variation at the S100B Gene Associates with Vaso-Occlusive Manifestations in Sickle Cell Disease
In sickle cell disease (SCD) polymerization of hemoglobin S under deoxygenated conditions causes vaso-occlusion, which can manifest as acute pain crisis and progressive bone/organ damage. Molecular studies have attributed vaso-occlusion to elevated vascular adhesion and inflammatory responses, whereas the genetic regulation has only recently been assessed.Genomic DNA isolated from peripheral blood mononuclear cells (PBMCs) was hybridized to Illumina Human 610-Quad SNP array for the PUSH and Walk-PHaSST cohorts and to Affrymetrix SNP 6.0 array for the Howard SCD expression cohort. Single nucleotide polymorphisms (SNPs) for ...

Gastroparesis: Current Opinions and New Endoscopic Therapies
Gastroparesis is a disease with a complex pathophysiology that is not yet fully understood. Antroduodenal hypomotility, impaired fundic accommodation, and pylorospasm are believed to play major roles in delaying gastric emptying. Patients with  gastroparesis suffer from frequent nausea, vomiting, earlier satiety, regurgitation, and so forth. Diabetes is the most common cause. Other causes include gastrointestinal surgery, some disorders of the nervous system, such as Parkinson disease and stroke, and some medicines, such as tricyclic ant idepressants, calcium channel blockers, and opiate pain relievers and others.

The Influence of Microneedles on the Percutaneous Penetration of Selected Antihypertensive Agents: Diltiazem Hydrochloride and Perindopril Erbumine.
Abstract It is well documented in the scientific literature that high blood pressure can lead to cardiovascular disease. Untreated hypertension has clinical consequences such as coronary artery disease, stroke or kidney failure. Diltiazem hydrochloride (DH), a calcium-channel blocker, and perindopril erbumine (PE), an inhibitor of the angiotensin converting enzyme are used for the management of hypertension. This project will examine the effect of microneedle rollers on the transport of DH and PE across pig ear skin. The use of the transcutaneous route of administration reduces and in sometimes eliminates the trau...

TRPM2: a candidate therapeutic target for treating neurological diseases.
Abstract Transient receptor potential melastatin 2 (TRPM2) is a calcium (Ca2+)-permeable non-selective cation channel belonging to the TRP ion channel family. Oxidative stress-induced TRPM2 activation provokes aberrant intracellular Ca2+ accumulation and cell death in a variety of cell types, including neurons. Aberrant TRPM2 function has been implicated in several neurological disorders including ischemia/stroke, Alzheimer's disease, neuropathic pain, Parkinson's disease and bipolar disorder. In addition to research identifying a role for TRPM2 in disease, progress has been made in the identification of physiolog...

A Review of Mathematical Models for Muscular Dystrophy: A Systems Biology Approach
Discussion With new developments in computational power and data availability, a growing amount of research is using a systems biology approach to understand pathogenesis and progression of disease. Effective and integrated in vitro and in silico models could inform biological phenomena, even without the need of a living subject. For instance, over the last few decades, collagen hydrogel with muscle derived cells (CHMDCs) have promised to revolutionize in vitro experiments and tissue engineering. For CHMDCs to reach the envisioned use, verification by use of mathematical simulations are needed. Recently while examining sha...

Vitamin D supplementation for sickle cell disease.
CONCLUSIONS: We included only one low-quality clinical study which had a high risk of bias with regards to incomplete outcome data. Therefore, we consider that the evidence is not of sufficient quality to guide clinical practice. Until further evidence becomes available, clinicians should consider the relevant existing guidelines for vitamin D supplementation (e.g. the Endocrine Society Clinical Practice Guidelines) and dietary reference intakes for calcium and vitamin D (e.g. from the USA Institute of Medicine). Evidence of vitamin D supplementation in sickle cell disease from high quality studies is needed. Well-designed...

Guideline of neuropathic pain treatment and dilemma from neurological point of view.
Authors: Yang CM, Chen NC, Shen HC, Chou CH, Yeh PS, Lin HJ, Chang CY, Cheng TJ, Lin KC Abstract Neuropathic pain is a complicated symptomatic disease as migraine in recent years. Not because the pain character differed from the nociceptive inflammatory symptoms but because of its complexity of mechanisms. Though peripheral sensitization, ectopic discharge, central sensitization, central re-organization and loss of inhibition play part of roles in mechanisms, however, based on this mechanistic treatment, the outcome still disappointed physicians and patients, exampled as central post-stroke central pain (CPSP). The...

8 Reasons You Get Dizzy
SPECIAL FROM Grandparents.com Who hasn’t gotten up quickly from sitting down and felt a little bit dizzy? Or had a stomach virus and things spun a bit? But while dizziness can be a side effect of minor health issues, it can also be a sign of a serious health problem. “Dizziness is absolutely not normal,” says Donnica Moore, M.D., president of Sapphire Women’s Health Group in Chester, N.J. “It tells you that something is wrong. It could be something simple and very easy to fix or it could be a sign of something else going on in your body.” Dizziness is a more common complaint among older adults—probably bec...

Prognostic Value of Coronary Computed Tomography Angiography in Stroke Patients
The predictive value of coronary computed tomography angiography (CCTA) in stroke patients has not yet been established. We investigated the prognostic value of coronary artery disease (CAD) detection by CCTA, and determined the incremental risk stratification benefit of CCTA findings as compared to coronary artery calcium scores (CACS) in ischemic stroke patients without chest pain.

Pharmacological Management of Central Post-Stroke Pain: A Practical Guide
Abstract Pain is one of the most troublesome sequelae of stroke. Some of this post-stroke pain is caused by the brain lesion itself; this is called central post-stroke pain (CPSP). Although the prevalence of CPSP is low (1–8 %), persistent, often treatment-resistant, painful sensations are a major problem for stroke patients. The pathogenesis of CPSP remains unknown, but suggested underlying causes include hyperexcitation in the damaged sensory pathways, damage to the central inhibitory pathways, or a combination of the two. For pharmacological treatment, amitriptyline, an adrenergic antidepressant, is current...
