Research helps unpick long-standing mystery about how dietary fibre supresses appetite

New research has helped unpick a long-standing mystery about how dietary fibre supresses appetite. In a study led by Imperial College London and the Medical Research Council (MRC), an international team of researchers identified an anti-appetite molecule called acetate that is naturally released when we digest fibre in the gut.

Multifunctional microcapsules can be produced from tannic acid and metals

Microcapsules with a broad spectrum of applications in biomedicine, catalysis, and technology can be produced by using plant-derived, phenolic tannic acid and a variety of metals. The capsules are formed by a simple self-assembly process, and their properties can be controlled through the choice of metal, as demonstrated by a team of Australian and German researchers in the journal Angewandte Chemie.

Study lays groundwork for PET imaging studies on human Menkes disease

Scientists at the RIKEN Center for Life Science Technologies have used PET imaging to visualize the distribution in the body of copper, which is deregulated in Menkes disease, a genetic disorder, using a mouse model. This study lays the groundwork for PET imaging studies on human Menkes disease patients to identify new therapy options.

Imaging cancer in children using MRI: an interview with Dr. Heike E. Daldrup-Link, Stanford University School of Medicine

There have been a number of scientific publications recently that suggest that the radiation exposure from imaging tests can induce secondary cancers later in life.

Plaque in brain could guide treatment decisions for patients at risk for Alzheimer's

Brain imaging using radioactive dye can detect early evidence of Alzheimer's disease that may predict future cognitive decline among adults with mild or no cognitive impairment, according to a 36-month follow-up study led by Duke Medicine.

Omeros doses first patient in second Phase 2 clinical trial of OMS824

Omeros Corporation today announced dosing of the first patient in a second Phase 2 clinical trial of OMS824, the company's phosphodiesterase 10 (PDE10) inhibitor being developed for the treatment of schizophrenia, Huntington's disease (HD) and other cognitive disorders. The Phase 2 trial will evaluate the tolerability, safety, pharmacokinetics and performance on a battery of tests in patients with symptomatic HD.

Study shows increased brain reactivity may facilitate memorisation of dreams

Some people recall a dream every morning, whereas others rarely recall one. A team led by Perrine Ruby, an Inserm Research Fellow at the Lyon Neuroscience Research Center (Inserm/CNRS/Universit- Claude Bernard Lyon 1), has studied the brain activity of these two types of dreamers in order to understand the differences between them.

Omeros announces additional positive data from OMS824 Phase 1 program

Omeros Corporation today announced additional positive data from its Phase 1 program for OMS824, the lead compound in Omeros' phosphodiesterase 10 (PDE10) program. This clinical trial evaluated the extent to which OMS824 binds to PDE10, an enzyme expressed in the region of the brain that has been linked to a wide range of diseases that affect cognition. In the latest cohort enrolled in this trial, OMS824 achieved a high of approximately 70‑percent engagement at PDE10 without evidence of extrapyramidal symptoms (EPS).

Omeros announces positive results from Phase 2a trial of OMS824 in patients with schizophrenia

Omeros Corporation today announced positive results from a Phase 2a clinical trial of OMS824, the company's phosphodiesterase 10 (PDE10) inhibitor, in which the drug was well tolerated and demonstrated comparable systemic pharmacokinetics when administered alone and concomitantly with approved antipsychotic agents in patients with schizophrenia. OMS824 selectively inhibits PDE10, an enzyme expressed in areas of the brain linked to a wide range of diseases that affect cognition, including schizophrenia and Huntington's disease.

Increased inflammation following infection impairs brain's ability to form spatial memories

Increased inflammation following an infection impairs the brain's ability to form spatial memories - according to new research. The impairment results from a decrease in glucose metabolism in the brain's memory centre, disrupting the neural circuits involved in learning and memory.

PET imaging of brain reveals ketamine may act as antidepressant by regulating serotonin activity

Ketamine is a potent anesthetic employed in human and veterinary medicine, and sometimes used illegally as a recreational drug. The drug is also a promising candidate for the fast treatment of depression in patients who do not respond to other medications.

Drugs to treat type 2 diabetes may have different effects on hearts of men and women

Widely used treatments for type 2 diabetes have different effects on the hearts of men and women, even as the drugs control blood sugar equally well in both sexes, according to researchers at Washington University School of Medicine in St. Louis.

18F-FDOPA imaging can help distinguish radiation-induced lesions in patients with brain metastases

Imaging with the molecular imaging tracer 18F-FDOPA can help distinguish radiation-induced lesions from new tumor growth in patients who have been treated with radiation for brain metastases, according to new research published in The Journal of Nuclear Medicine. Using this amino acid tracer, researchers found that physicians could accurately differentiate the two types of lesions 83 percent of the time. Progression-free survival could also be predicted through evaluating the 18F-FDOPA imaging results.

Using radiation models to improve cancer therapies: an interview with Adrian Treverton, COO of Xstrahl and Jean-Pierre Wery, President of Crown Bioscience

What we are trying to do is take a cancer model like the PDX model (patient-derived tumor xenograft), which is a human-derived cancer growing in an in vivo model and apply radiation to that model.
