Fulminant hepatic failure attributed to infection with human herpesvirus 6 (HHV-6) in an immunocompetent woman: A case report and review of the literature.

Mild disease due to human herpesvirus-6 (HHV-6) has been reported in healthy children. Severe disease due to this virus can occur in immunocompromised patients but is rarely reported in previously healthy adults. We report the case of a previously healthy woman who presented with a skin rash, mild upper respiratory symptoms, and abdominal pain and succumbed to fulminant hepatic failure attributed to infection with HHV-6B.

A fatal case of acute HHV-6 myocarditis following allogeneic haemopoietic stem cell transplantation.

Human herpesvirus 6 (HHV-6) is an ubiquitous virus that can reactivate in immunocompromised hosts, resulting in diverse clinical sequelae. We describe a case of fatal acute HHV-6 myocarditis in a patient who underwent allogeneic haemopoietic stem cell transplantation (HSCT). To our knowledge, this is the first reported case of biopsy proven HHV-6 myocarditis post-HSCT.

Stretch reduces central core lesions and calcium build-up in tenotomized soleus.

The incidence of skeletal muscle tendon rupture is increasing. The unloaded, shortened muscle undergoes rapid degeneration. Rehabilitation takes 10-12 weeks and includes stretch therapy.

Endothelium-derived 2-arachidonylglycerol: an intermediate in vasodilatory eicosanoid release in bovine coronary arteries.

Acetylcholine stimulates the release of endothelium-derived arachidonic acid (AA) metabolites including prostacyclin and epoxyeicosatrienoic acids (EETs), which relax coronary arteries. However, mechanisms of endothelial cell (EC) AA activation remain undefined. We propose that 2-arachidonylglycerol (2-AG) plays an important role in this pathway.

Passive stretch inhibits central corelike lesion formation in the soleus muscles of hindlimb-suspended unloaded rats.

Hindlimb suspension unloading (HSU) is a ground-based model simulating the effects of microgravity unloading on the musculoskeletal system. In this model, gravity causes the hind foot of the rat to drop, opening the front of the ankle to 90-105 degrees plantar flexion at rest. As HSU proceeds, the normal weight-bearing angle of 30 degrees dorsiflexion is achieved progressively less, and the contraction range of soleus is abbreviated.
