Possible molecular link between circadian rhythm disturbances and increased inflammatory response

Scientists have known for some time that throwing off the body's circadian rhythm can negatively affect body chemistry. In fact, workers whose sleep-wake cycles are disrupted by night shifts are more susceptible to chronic inflammatory diseases such as diabetes, obesity and cancer.

New compound effective at blocking damage to the retina in diabetic retinopathy

Researchers at the University of Michigan Kellogg Eye Center have identified a compound that could interrupt the chain of events that cause damage to the retina in diabetic retinopathy. The finding is significant because it could lead to a novel therapy that targets two mechanisms at the root of the disease: inflammation and the weakening of the blood barrier that protects the retina.

MRI useful for identifying bone lesions in diabetic feet

Identification of specific bone lesions in the feet of patients with diabetes can be achieved with magnetic resonance imaging, show study findings.

Tumor necrosis factor may play a key role in how light at night leads to depression

Chronic exposure to dim light at night can lead to depressive symptoms in rodents -- but these negative effects can be reversed simply by returning to a standard light-dark cycle, a new study suggests.

Limewater combination therapy can reduce root canal endotoxins

Treating root canals with a combination of chlorhexidine gel and calcium hydroxide results in significant reduction of endotoxins and neutralization of cytotoxic effects compared with the gel plus polymyxin B or saline, report Brazilian researchers.

Altered immune function in relatives of schizophrenia patients

Schizophrenia patients and their unaffected first-degree relatives exhibit immune system alterations compared with mentally healthy individuals, researchers report.

Researchers discover unknown mechanism that promotes growth and spread of cancer

Tiny vesicles released by tumors cells are taken up by healthy immune cells, causing the immune cells to discharge chemicals that foster cancer-cell growth and spread, according to a study by researchers at The Ohio State University Comprehensive Cancer Center - Arthur G. James Cancer Hospital and Richard J. Solove Research Institute (OSUCCC - James) and at Children's Hospital in Los Angeles.

Herpes zoster vaccine recommendations questioned in patients on biologics

Administration of the live attenuated herpes zoster vaccine is not associated with an increased risk for shingles shortly after vaccination in patients receiving biologic treatments for immune-mediated diseases, researchers report in JAMA.

TNF-α levels linked to lithium response in BD patients

Patients with bipolar disorder who have a poor response to lithium treatment have significantly higher serum levels of tumor necrosis factor-α than those with a good response, researchers report.

Specific cytokine levels altered in BD patients

Levels of certain cytokines differ between bipolar disorder patients and mentally healthy individuals, as well as between manic and euthymic patients with the mood disorder, results from a systematic review and meta-analysis show.

Toxins and cell death: Interview with Professor Denise Montell

There are multiple kinds of cell death. Cells can undergo programmed cell death, which is a series of events that undergoes a predictable order at certain times during development.

Live zoster vaccine associated with reduced risk of HZ in patients with immune-mediated diseases

Although some have suggested that patients receiving medication for immune-mediated diseases such as rheumatoid arthritis or psoriasis may be at increased risk of herpes zoster (HZ; shingles) shortly after receipt of the vaccine, an analysis that included nearly 20,000 vaccinated Medicare beneficiaries finds that the live zoster vaccine is not associated with an increased risk of HZ shortly after vaccination in patients currently treated with biologics, and that it is associated with a significantly reduced longer-term risk of HZ in patients with an immune-mediated disease, according to a study in the July 4 issue of JAMA.

Shingles vaccine may not increase risk of varicella in people with auto-immune diseases

New research from the University of Alabama at Birmingham casts doubt on the long-standing belief that the vaccine for shingles should not be given to patients taking biologics for auto-immune diseases such as rheumatoid arthritis.

Inhibiting immune response during initial multi-drug therapy could speed TB treatment time

Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could - paradoxically - shorten treatment time for the highly contagious lung infection according to new research from Johns Hopkins Children's Center and the Center for TB Research.

TB research finds body’s own response helps TB bacteria survive

Inhibiting a key immune response in mice during initial multi-drug treatment for tuberculosis could — paradoxically — shorten treatment time for the highly contagious lung infection according to new research from Johns Hopkins Children’s Center and the Center for TB Research. Shorter duration of drug therapy is key, researchers say, to increase treatment compliance for the growing global health threat posed by the disease.

Omega-3 fatty acid supplements can reduce inflammation in overweight older adults

New research shows that omega-3 fatty acid supplements can lower inflammation in healthy, but overweight, middle-aged and older adults, suggesting that regular use of these supplements could help protect against and treat certain illnesses.
