Chronically available alcohol escalates drinking in mice and a single injection of the immune activator lipopolysaccharide can mimic this effect and result in a persistent increase in alcohol consumption. We hypothesized that chronic alcohol drinking and lipopolysaccharide injections will produce some similar molecular changes that play a role in regulation of alcohol intake. We investigated th...

synovial hemangioma is a rare benign malformation of the synovium. it presents frequently in the knee with pain, tenderness, intermittent swelling and recurrent hemarthrosis. mri can be helpful in diagnosis of synovial hemangioma. in this paper, we present a 45-year-old lady with chronic symptoms and obscure clinical symptoms for 35 years which finally diagnosed and managed arthroscopically as ...

Psoriasis is a chronic immune-mediated inflammatory disease of unknown etiology. Unlike other chronic inflammatory diseases receiving continuous treatment, psoriasis has traditionally been treated intermittently secondary to concern for cumulative toxicity of conventional systemic therapies. However, the development of targeted anti-inflammatory biologic agents allowed for continuous therapy fo...

The use of inhaled therapies for chronic respiratory infections in cystic fibrosis represents a substantive treatment burden to patients. In this paper, we review the evidence supporting two commonly used inhaled antibiotic regimens for chronic respiratory infections - continuous vs. intermittent (28 days on followed by 28 days off) therapy. We included trials of good methodological quality and...

Chronic ethanol consumption causes structural and functional reorganization in the hippocampus and induces alterations in the gene expression of gamma-aminobutyric acid type A receptors (GABAARs). Distinct forced intermittent exposure models have been used previously to investigate changes in GABAAR expression, with contrasting results. Here, we used repeated cycles of a Chronic Intermittent Et...

One of the major manifestations of obstructive sleep apnea is profound and repeated hypoxia during sleep. Acute hypoxia leads to stimulation of the peripheral chemoreceptors, which in turn increases sympathetic outflow, acutely increasing blood pressure. The chronic effect of these repeated episodic or intermittent periods of hypoxia in humans is difficult to study because chronic cardiovascula...
