Sugar isn't the only enemy of teeth. Acids found in diet and regular soda, energy drinks, juice and wine can erode tooth enamel, leading to tooth decay. There are a few ways to minimize the risk of damage from acidic foods and drinks such as timing consumption: Eating acidic foods as part of a meal helps neutralize and eliminate acids. Before bedtime is the worst time to consume acidic foods, because saliva production decreases during sleep. Saliva helps neutralize and dilute acids. Brushing teeth with fluoride toothpaste 30 minutes before consuming acidic foods or drink is most beneficial.

Significant pre-clinical results on the anti-tumor activity of Titanocene Y on human breast tumors and in a mouse model have just been published. In the mouse model, a decrease not only in tumor growth but also a reduction in tumor volume to around one-third was observed for the first time. In the human breast cancer, Titanocene Y showed cell death induction comparable to the widely-used chemotherapy drug Cisplatin.

Obesity prevalence has increased significantly among adults and children in the U.S. over the last two decades. A new study reveals that characteristics of neighborhoods, including the area’s income level, the built environment, and access to healthy food, contribute to the continuing obesity epidemic.

A researcher at the Johns Hopkins Institute of Genetic Medicine has led the effort to compile to date the largest free resource of experimental information about human proteins. The research team describes how all researchers around the world can access this data and speed their own research.

Researchers are identifying innovative therapeutics for sickle cell anemia that focus on specific factors in the disease's progression, such as the important role of hydration of the red blood cells. A novel small molecule therapy called senicapoc showed efficacy in maintaining hydration of red blood cells and increasing hemoglobin levels in patients with sickle cell anemia.

Parts of feline immunodeficiency virus isolated from wild lions have undergone substantial genetic recombination. The sequencing of the two full FIV genomes of different lion subtypes shows the importance of whole-genome analysis in understanding complex genetic events. These findings will be relevant to big cat conservation and developing more effective animal models for HIV.

People with manic depression have a distinct chemical signature in their brains, according to a new study. The research may also indicate how the mood stabilizers used to treat the disorder counteract the changes in the brain that it appears to cause. Manic depression, which is also known as bipolar disorder, is a debilitating psychiatric condition characterised by alternating mania and depression, affecting about one in every hundred people worldwide.

Cerebral imaging reveals that human infants are sensitive to numerical quantity at a very early age and that the basic dorsal/ventral functional organization is already in place in the infant brain.

A cellular protein that helps guide immune cells to the gut has been newly identified as a target of HIV when the virus begins its assault on the body's immune system, according to researchers. Scientists identify a cell adhesion molecule known as integrin alpha 4 beta 7 as a potentially important receptor for HIV.

Researchers analyzing prostate tumors have identified differences in gene expression (the degree to which individual genes are turned on or off) between African-American and European-American men that show the existence of distinct tumor microenvironments (the area that includes the tumor and the surrounding non-cancerous tissue) in these two patient groups. Many of the genes that are differentially expressed between the tumors of African-American and European American men are related to the immune system.
