Skeletal progenitor cells differentiate into cartilage cells when one master gene actually suppresses the action of another. Skeletons are made of bone and cartilage cells that are differentiated from the same multipotent stem cell, which gives rise to bone, cartilage, fat and fibroblasts.
Technology developed for roadside fingerprints using hand-held devices — announced in the media this month — has also been pioneered in identifying the dead, it has been revealed.
Rice University chemists have discovered how to assemble gold and silver nanoparticle building blocks into larger structures based on a novel method that harkens back to one of nature’s oldest known chemical innovations — the self-assembly of lipid membranes that surround all living cells. The research appears in the Nov. 29 issue of the Journal of the American Chemical Society. It could help scientists design everything from better catalysts to potent new anti-cancer drugs.
A new study shows that blood flow to the legs is relatively normal in people with diastolic heart failure, suggesting other potential causes of their inability to do everyday activities, according to researchers at Wake Forest University Baptist Medical Center.
Alcohol can help people initially fall asleep, but leads to poor-quality sleep later in the night. Escalated consumption of alcohol to aid sleep can lead to alcoholism. Inaccurate sleep perceptions among alcoholics in early recovery may predict relapse to drinking.
Popular and clinical lore support the strong connection between smoking and alcohol consumption. Adolescent smokers appear to have a greater vulnerability to developing alcohol-use disorders. Results indicate that smoking “primes” the brain for subsequent addiction to alcohol and possibly other drugs.
New research uses an electroencephalogram (EEG) to look for a connection between brain activity thought to reflect trait-like differences in emotionality and alcoholism. Findings show an asymmetry of activity in the left and right frontal areas of the brain.
Laboratory results with the NPRL2 tumor suppressor gene demonstrated that infusions of NPRL2 nanoparticles in combination with cisplatin resulted in a 90 percent inhibition of tumor growth in human lung cancer cells compared to control treatments, reported Introgen Therapeutics, Inc. (Nasdaq: INGN – News).
Bacteria that can cause deadly infections in humans and animals have shown promise in treating cancer by ?eating? tumors from the inside out. Now, two new studies at the Johns Hopkins Kimmel Cancer Center have demonstrated that, combined with specially-packaged anti-cancer drugs, the bacterial therapy?s prospects for cancer eradication have dramatically improved.
