The Scottish scientists work above creation of a medicine reducing appetite and that makes women feel sexy.
Tests of the type-2 gonadotropin-releasing (this hormone is distributed in the brain in areas that affect reproductive behaviour) have proved successful in lab animals.
It is supposed that the medicine can appear the nearest 10 years
A pill which boosts the sexual desire and helps with dieting could help many people suffering from adiposity

Two groups of independent researchers have found out three widespread genetic mutations considerably increasing risk of cardiovascular diseases at white Europeans and Americans.
During one of researches, experts have analysed samples of a blood of 28 thousand patients with cardiovascular diseases, and healthy people who have made control group. As a result, two have been found out mononucleotide (caused by change of one part in a chain of DNA) mutations of genes of 9-th pair chromosomes which met at sick participants is much more often.
Presence of one of the taped genes at participants of the European parentage enlarged risk of ischemic illness of heart by 25 %, and at presence of two repetitions of a gene, the risk increased on 40 %. Thus, at Afro-Americans of similar law to tap it was not possible.
According to researchers, the genes bound to increased risk of illnesses of heart, are rather widespread:
More than half of Europeans are bearers of one repetition of one of them, and at a quarter, they are present at both chromosomes of 9-th pair.
In other research, it has been involved 17 thousand person. The Icelandic scientists managed to find out other mutation also localized in 9-th chromosome. Presence of two repetitions of a mutant gene twice enlarged risk of heart attacks at early age.
Bearersof two repetitions of this gene are up to 20 % of white Europeans and Americans.
Early detection of the specified genetic variations should help to physicians to lower essentially risk of cardiovascular diseases at this the patients concerning group of risk.
At the same time despite of doubtless value of the information received by researchers, as a whole the risk of cardiovascular diseases is defined not so much by genes, and factors of an environment: smoking, features of meal, an inactive way of life and others

Scientists from the USA and Great Britain inform on successful end of tests of a new medicine for osteoporosis which needs to be entered once a year. Scale research has shown, that application of a preparation for the women with menopause, reduces risk of fractures of bones dangerous to a life on 40 %.
Osteoporosis – age disease which leads to depression of density of osteal substance and the increased fragility of bones. Fractures of large bones, first of all femoral, are especially dangerous to elderly patients. According to the British statistics, one of five patients with such fracture perishes from accompanying complications and infections within several months after a trauma.
Modern medicines for an osteoporosis are calculated on regular, daily or weekly reception, therefore their efficiency often decreases because of an indiscipline of patients.
The new preparation , which active substance is a zoledronic acid, acts an extent of 12 months after a unitary intravenous injection. The previous researches of a preparation have shown, that its{his} application leads to restoration of osteal mass. The new tests, proceeded three years, should show, that the medicine really reduces risk of fractures of bones.
In research it has been involved 8000 women . Within three years the participant have three injections contained 5 mg of a zoledronic acid.
As a result, among patients has been 70 percent reduction of risk of fractures of spinal column.
Frequency of fractures of a femur has decreased on 41 %, frequency of other, less dangerous fractures – on 25 %.
