Computed tomography technology shows anorexia impairs adolescent bone development

Children and teenagers with even mild cases of anorexia exhibit abnormal bone structure, according to a new study appearing in the December issue of Radiology and presented at the annual meeting of the Radiological Society of North America (RSNA).

Proton therapy may reduce serious side effect of lung cancer treatment

Patients with locally advanced lung cancer who receive chemotherapy and proton therapy, a specialized form a radiation therapy only available in a few centers in the United States, have fewer instances of a serious side effect called bone marrow toxicity than patients who receive chemotherapy and another type of radiation therapy called intensity modulated radiation therapy (IMRT), according to a study presented at the 2008 Chicago Multidisciplinary Symposium in Thoracic Oncology, sponsored by ASTRO, ASCO, IASLC and the University of Chicago.

Timing is everything for some heart attack patients

There is strong evidence that getting to the hospital quickly during a heart attack is critical, since early treatment saves both lives and heart muscle. And if the responsible coronary artery is completely blocked, it should be opened as soon as possible.

H5N1 protein hides in tiny tubules

A protein found in the virulent avian influenza virus strain called H5N1 forms tiny tubules in which it "hides" the pieces of double-stranded RNA formed during viral infection, which otherwise would prompt an antiviral immune response from infected cells, said Baylor College of Medicine researchers in an online report in the journal Nature.

Molecule stops DNA replication in its tracks

When a dividing cell duplicates its genetic material, a molecular machine called a sliding clamp travels along the DNA double helix, tethering the proteins that perform the replication.

People with autism less influenced by gut instincts

People with autism-related disorders are less likely to make irrational decisions, and are less influenced by gut instincts, according to research funded by the Wellcome Trust. The study adds to the growing body of research implicating altered emotional processing in autism.

Surface analysis exposes counterfeit medicines

CERAM Surface and Materials Analysis has published a white paper highlighting how surface analysis can expose counterfeit medicines. It describes how technologies such as X-ray photoelectron spectroscopy (XPS) and Time-of-Flight Secondary Ion Mass Spectroscopy (ToFSIMS) are being used in novel ways to not only analyse the composition of various pharmaceuticals, but also to determine differences in the manufacturing processes involved.

Study specifies chemical pathway for ions through the cell membrane

Life ultimately depends on the traffic of tiny charged particles through porous proteins studding the membrane surrounding every cell. In research published in Nature, scientists at The Rockefeller University have for the first time mapped a stepping-stone pathway of amino acids that these charged particles, or ions, follow across cell membranes.

Scientists image transfer of antibodies from mother's milk, to baby's gut

The transportation of antibodies from a mother to her newborn child is vital for the development of that child's nascent immune system. Those antibodies, donated by transfer across the placenta before birth or via breast milk after birth, help shape a baby's response to foreign pathogens and may influence the later occurrence of autoimmune diseases.

Many receptor models used in drug design may not be useful after all

It may very well be that models used for the design of new drugs have to be regarded as impractical. This is the sobering though important conclusion of the work of two Leiden University scientists published in Science this week.
