The Renin Angiotensin System as a Therapeutic Target in Traumatic Brain Injury.

Traumatic brain injury (TBI) is a major public health problem, with limited pharmacological options available beyond symptomatic relief. The renin angiotensin system (RAS) is primarily known as a systemic endocrine regulatory system, with major roles controlling blood pressure and fluid homeostasis. Drugs that target the RAS are used to treat hypertension, heart failure and kidney disorders.

Assessment of corn starch as substitute for agarose in DNA gel electrophoresis.

Objective: The use of agarose in nucleic acid electrophoresis is the gold standard. However, agarose is very expensive and not readily available in resource limited developing countries like Ghana. Hence, finding a more affordable and readily available alternative to agarose will be a major boost to molecular research in developing countries.

A Rare Case of Thyrotoxic Periodic Paralysis After Epidural Steroid Injection: A Case Report and Literature Review.

BACKGROUND Thyrotoxic periodic paralysis (TPP) is a rare cause of acute paralysis, which if not promptly recognized and treated, can lead to significant morbidity and mortality. TPP can be precipitated by several factors, including a high carbohydrate diet and exercise. This report is of a rare case of TPP after epidural steroid injection in a young man, with a review of the literature of previous cases.

Microglial Activation Results in Inhibition of TGF-β-Regulated Gene Expression.

Chronic inflammation mediated by persistent microglial activation is associated with the pathogenesis of neurodegenerative diseases. The mechanisms underlying chronic microglial activation are poorly understood. We have previously shown that anti-inflammatory TGF-β signaling is inhibited in LPS-treated microglia.
