Blood Pressure Drugs maintain muscle strength

...ibitors prevent high blood pressure by blocking an enzyme that causes blood vessels to constrict. The drugs also help to preserve muscle strength in patients suffering from congestive heart failure (CHF). Researchers said the drugs could also help elderly people who do not suffer from heart problems...

Honey curbs bacteria in the oral cavity

...for Dental Research annual meeting this month. An enzyme in honey that produces hydrogen peroxide is the key to the antimicrobial activity of honey, according to Dr. Peter C. Molan, associate professor of biochemistry at the University of Waikato, New Zealand. Research results from University of Waikato ...

Drug to treat lung cancer shows promise

...ears to work by increasing the body's levels of an enzyme called Gst that ordinarily detoxifies dangerous substances, such as tobacco smoke. Levels of this enzyme can be abnormally low in people long exposed to tobacco. Experts say large-scale testing will be ne...

Early Warning System For Breast Cancer

...ors. RhoC, whose full name is RhoC-GTPase, is an enzyme involved in changing the internal skeleton of a cell - changes that allow a cell to polarize or move. That ability is important in muscle cells, which produce a lot of RhoC. But in cancerous non-muscle cells, RhoC is key to the structural changes tha...

Drug stabilizes cancer growth

...ny. Phenoxodiol appears to work by inhibiting an enzyme that is vital for cancer growth. With the drug interfering with this enzyme rather than directly attacking cells, normal healthy cells are left untouched, reducing side effects...

Hypertensive drugs may cause cough

...ressure medication.// The angiotensin-converting enzyme (ACE) inhibitors are often used to treat high blood pressure, heart failure and other cardiac conditions. But up to 40% of people on ACE inhibitors are troubled by a cough. The side effect is not considered serious by doctors, but it is the most comm...

Hepatitis E virus made impotent

A ribozyme, an enzyme that can be used to kill the deadly Hepatitis E virus has been designed by Indian scientists. The ribozyme had been designed using the viral clones and would kill the virus by cutting RNA.// The efficacy of the ribozyme was being tested on ani...

Genetic innovation

...omosome 15, called CYP19, codes for aromatase - an enzyme that converts testosterone into oestrogen in both sexes. Oestrogen influences height because it is responsible for bones fusing over at the ends, which stops people growing. A person's height depends on both genetic and environmental influences. Pr...

A ray of light on Cardiology

The angiotensin-converting enzyme (ACE) inhibitor ramipril, used for the treatment of hypertension, can retrieve, and may even prevent, left ventricular hypertrophy (LVH), thereby lowering the risk of stroke and myocardial infarction (MI), a new study has shown.Results from the landm...

A new genetic label for stroke

...responsible for producing paraoxonasc, or PON1, an enzyme that helps HDL cholesterol prevent the oxidation of LDL cholesterol. This process plays a major role in the development of heart and blood vessel disease leading to stroke. Blood samples of 120 people who had suffered a stroke before age 44 were com...
