Dr Mohamed A Bassiouny, lead author of the report, instructs those experiencing tooth erosion to first, identify the culprit source of erosion, possibly with the help of a dental professional.

He says that the individual should then determine and understand how this source affects the teeth, in order to implement measures to control and prevent further damage.
Finally, he writes, the person should stop or reduce consumption of the suspected food or beverage to the absolute minimum.

He says that information about the acid content of commonly consumed foods or beverages is usually available online or on the product’s label. According to him, it is also recommended to seek professional dental advice in order to possibly restore the damaged tissues.

Scientists find 3,600 disease ‘switches’
A collaborative study conducted by researchers at University of Copenhagen and the Max Planck Institute in Germany has led to the identification of no less than 3,600 molecular switches in the human body, which may prove to be a crucial factor in human ageing and the onset and treatment of cancer, Alzheimer’s disease and Parkinson’s disease.
Lead researcher Matthias Mann, University of Copenhagen and the Max Planck Institute for Biochemistry, has revealed that the 3,600 acetylation switches were detected in 1,750 different proteins.

“This is more than just a technological achievement, it has also expanded the number of known acetylation switches by a factor of six, and it gives us for the first time a comprehensive insight into this type of protein modification,” says Professor Mann.

Fish unlikely to benefit Indians with dementia
Fish is known to influence the onset and severity of dementia, however, a new study has revealed that Indian people are unlikely to benefit from it.

Oily fish are rich in Omega-3 fatty acids and have been positively related to cognitive function in later life.

An international team of researchers studied 14,960 participants, aged 65 and less, living in China, India, Cuba, the Dominican Republic, Venezuela, Mexico, and Peru.
They found that each country, except India, showed an inverse association between fish consumption and dementia prevalence.

Another study had recently shown that people who live alone in middle age face nearly double the risk of developing dementia in later life compared with married or cohabiting counterparts.

The study suggested that having a partner offers protection against mental decline in later life.

The researchers also found that people who live alone in middle age and are widowed or divorced are three times more likely to develop dementia, as are people who are single at middle-aged but also when they are older.

How flu virus attacks the lungs
Shedding new light on how influenza virus attacks the lungs, a new study conducted
by researchers at the University of Alabama at Birmingham (UAB) and Southern
Research Institute has provided targets for new treatments.

Writing about their findings in the online edition of the ‘Federation of American Societies for Experimental Biology’, the researchers have revealed that a protein in influenza virus called M2, which helps it multiply, also damages lung epithelial cells, causing fluid build-up in the lungs.

They say that the accumulation of fluid in the lungs makes it difficult for the patient to breathe and prevents oxygen from reaching the blood stream.
