A new study suggests that the risk of transmitting the virus that causes most cases of genital herpes could be cut in half by more testing and informing sexual partners of infection. The study is published in the July 1 issue of The Journal of Infectious Diseases, now available online.

A potentially ground-breaking treatment for nerve damage caused by diabetes has shown promising results in preclinical and early patient trials.

The researcher Zafira Castaño has discovered that the loss of a protein in the early phases of lung cancer favors tumor growth. This was the conclusion that the Doctor in Biochemistry reached in the dissertation which she defended at the University of Navarra.

Using small molecules containing platinum, Virginia Commonwealth University Massey Cancer Center researchers have created a process to inhibit a class of proteins important in HIV and cancer.

Neurochem Inc. (NASDAQ: NRMX; TSX: NRM) is pleased to announce that Neurobiology of Aging, one of the world's leading peer-reviewed medical journals in the fields of gerontology and neuroscience, has published an online version of a publication on the preclinical development of tramiprosate (3-amino-1-propanesulfonic acid; Alzhemed™), including efficacy results in a mouse model of brain amyloidosis. Tramiprosate (Alzhemed™) represents a potential new class of therapeutic agent and is Neurochem's investigational product candidate for the treatment of Alzheimer's disease (AD). The results presented in this paper include the amyloid binding and neuroprotective characteristics of tramiprosate (Alzhemed™) and provide evidence for the potential disease-modifying effect of this product candidate to slow or arrest the progression of AD.

Non-traumatic amputations – those caused by arterial blockages related to diabetes, smoking, obesity and vascular system complications – are occurring at an alarming rate. Yet physicians may be too quick to amputate as 85 percent of them may be preventable, according to the International Diabetes Foundation.

Reflooding of Iraq's destroyed Mesopotamian marshes since 2003 has resulted in a "remarkable rate of reestablishment" of native invertebrates, plants, fish, and birds, according to an article in the June issue of BioScience.

Methylphenidate (Ritalin) elevates norepinephrine levels in the brains of rats to help focus attention while suppressing nerve signal transmissions in the sensory pathways to make it easier to block out extraneous stimuli, a Philadelphia research team has found.

-A new imaging method has revealed early signs of emphysema in smokers with no external symptoms of the disease, according to a study published in the June issue of Radiology. The study, supported by the National Institutes of Health, details a new magnetic resonance imaging (MRI) technique that appears to be much more sensitive to lung changes than even the current modality of choice, computed tomography (CT).
