A study published in an open access re-examined PLoS Medicine revealed that the women in the developing countries, world should not be an early tracking of the cancer of the collar of l’ uterus which they need. The researchers Gakidou Emmanuel (University of Washington, Seattle, the United States), and its colleagues report/ratio that, while the society women of the developing countries are more at the risk to develop the cancer of the collar of l’ uteruses, some are treated efficiently. Moreover, there exist serious inequalities enters and within the countries relating to l’ access to tracking of the cancer of the collar of l’ uterus. Like the second most common cancer at the women (after breast cancer), the cancer of the collar of l’ uterus is the leading cause of death in the world. At one moment During 40 last years, thus qu’ a certain number of new cases of cancer of the collar of l’ uterus and the mortality of this disease was tiny room in the developed countries. The doctors and the health professionals is the large range of programs, such as the reason of this success for the public health. New world, however, have more raised incidence of cancer of the collar of l’ uterus, but very little d’ information was tracking. Gakidou and the d’ establishments; teaching, filtered by the investigations with l’ The World Health Organization (WHO), in order to better include/understand the problem of l’ information, and up to what point the possibility of testing the service was unequal. The data come from 57 countries and on all the levels of economic development. The researchers identified two types of cover: 1) the deposit rate - measured by the percentage from women who have gynaecological examination and test PAP during the three last years, and 2), the cover of crude oil - measured by the percentage of women who stated to have only one gynaecological examination constantly. L’ objective of these measurements revealed qu’ there exists a significant difference in tracking of cancer of the collar of l’ uterus rate enters the developed countries and the developing countries: 19% are in the developing countries, and 63% in the developed countries world were selected to answer the real cover. D’ other important statistics for l’ study, inter alia things: * Austria, more than 80% of the women effective May being in tracking. * Ethiopia and Bangladesh, 1% or less tracking effective. * More than 50% of the women n’ had ever received a gynaecological examination in 16 of the 57 studied countries. * 90% of the women, l’ Ethiopia, of Malawi and Bangladesh n’ forever have a gynaecological examination. As s’ was needed; there to wait, those which have the greatest exposure to snuff, sexual relations not protected and cancer from the collar of l’ uterus d’ other risk factors are the poor women, this group is also less likely to receive tracking effective. Since the women age, prices of tracking for the developing countries, although the fall among old women are more prone to a cancer of the collar of l’ uterus, ” Parantaminen an effective cover of the cancer of the collar of tracking, or to develop d’ other means of reducing the death rate of the cancer of the collar of l’ uterus in the whole world would have a significant impact on the reduction of the load of the disease, as well as the inequalities of world health. Nobody n’ strategy of work in the world has everywhere, it is thus important to consider a certain number of strategies - and probably - in the pays” , authors.

Independent laboratorial examinations confirmed that a baby of 16 months of boy in the Bangladesh, that is now is recovered, had the flu of birds, a representative of World Organisation of Health (THAT) declared earlier today, Friday. Because this is the first confirmed case of flu of birds in Bangladesh, it brings in the 15 total number of countries that is recorded cases of human infections leathal virus H5N2 of flu of poultry. THAT representative Gregory Hartl Reuters said: ” This affair is confirmed by CDC [American Centre of Control of Illnesses and Prevention] in the Atlas. He is first in .” The sick toddler became in January of running year, and that since then he has proceeded in complete derotation, he declared Hartl. Even if the sanitary beginnings in Bangladesh from the suspect case that was reported immediately, needed time for a sample from the baby will be supposed they are sent and are tryed in the USA, it said. The Authorities of Bangladesh H5N1 in poultry were found for first time in March of passed year, and from then have been destroyed roughly 2 millions eggs and 2 millions chickens, report Reuters. The virus henceforth has expanded in chickens, ducks and wild birds almost in entire the country: it was realised in 47 by the 64 provinces of country. Hartl said that it is inevitable, from the moment where became the illness in birds, that it would be one day it pollutes the person, but was still important for the fighting of his population of birds in order to they decrease the probabilities of pollution of persons from the virus. Bangladesh is a poor country roughly 150 millions persons with developing industry of poultry that has been affected by these facts. According to the government of Bangladesh, elements that were reported by the BBC, the slaughter led to damage of 60 millions dollars USA and above 1,5 millions workers lost their works. The experts believe that it is only subject of time before H5N1, which is altered the all hour, is converted in a executive that can expand easily between the persons and kills millions persons worldwide. This moment person it only can fish catches from the handling of polluted birds, and even then, it is enough difficult be polluted. However, the Authorities of Bangladesh, the health are mystified as for the way with which the small boy that was fished the virus because it lives in a over-populated reduced to poverty urban region of capital Dacca, far from avicolous exploitations, declared journalist of BBC in Dacca. According to THAT, up to the most recent confirmation of this affair, at the latest total elements for the flu of birds infections in persons, briefing in the dues April, showed 14 countries had been confirmed reports of flu of birds in persons from 2003. The world total of human cases is 382 (now 383), from which 241.

Researchers in the USA, studying mice it realised that these could turn the animals of” rythm or clock of organism that checks the availability of foods, fact that implies that the development dinners could help the persons adapt very body of clock, as an example, to face with jet lag or to get used shiftworking. The study was carried out by researchers in Beth Israel Deaconess Medical Center (BIDMC), in Harvard Medical School of , and is published today online, 23 May, in periodical Science. The primary biological clock of animals that is checked by a team of cells in the hypothalamus of brain that is known as suprachiasmatic core (SCN). The SCN scans the optical system for messages with regard to whether it is light or dark and passes these information in dorsomedial core (DMH), also in the hypothalamus. The DMH organises the organism when it sleeps also when he is awake, and the ups and downs of hormones and other bodily operations it suits. Does the system function well, when the foods are abundant? Animals” body clocks or rythm following the daily circle light and dark. But when is disturbed the availability of foods, as an example, provided that it is rendered available only at the duration of regular period of sleep, the animals it is in position they are turned rythm in a new model so that they are placed in vigilance (and obviously alarm), when the foods he is available. Did superior writer Dr Clifford Saper, that is chairman of Department of Neurology in the BIDMC, as well as colleagues, decide it searches the subject of mechanisms according to which a “? foods  it appears does predominate the most usual “  as fundamental way in order to it regulates [kirkadikoy] rythm. Is a important obstacle the fact that certain by the cells of SCN is named ” oscillato  also they exist elsewhere in the brain and in other spaces, as the stomach and the liver, and them also it plays some role it is for the establishment of   rythm. Saper said that: ” Dissecting this big interrelated system that it places .”  Thus, the simplified work with the use genetically modified mice that had a basic biological clock of gene, BMAL1, extinguish. Afterwards it used a institution it imports turn on BMAL1 genes in selectively departments of brain, a step each time. When the researchers provided the BMAL1 of institution in his SCN part hypothalamus, he was in position it restores mouse of rythm in answer in the light and dark changes, but not availability of food patterns. But when BMAL1 of institution in his DMH part hypothalamus, it was in position it restores mouse of rythm in answer on the availability of foods habits, but not the light and dark changes. The researchers in the conclusion that: “  This do results prove that dorsomedial hypothalamus it contains BMAL1 it is based oscillator that it can direct the foods entrainment   Thus, using this method progressive researchers found themselves the foods-clock in the DMH, as he explained Saper: “  We discovered that a united circle of hunger, followed from refeeding it activates the clock, so that it is faced effectively it surpasses the suprachiasmatic core and hijacks all of    rythm in a new area of hour that corresponds with the availability   The discovery could help individuals and shifts, said Saper: “  Modern person it can be in position they use this discoveries in one adoptive  , it said, explaining that it takes the medium individual for one week in order to they are adapted in 11 hours time area, as somebody that travels from the USA Japan, as an example, will be supposed does know,   because the biological clock of organism they can turn itself only a each small sum  &quot. However from the end of week, it is rather time to fly again the house, therefore it be useful wouldn’t we have a way of acceleration of process of adaptation, what the body that is used in order to it takes the new area of hour more fast? Saper indicates that with the change of schedules of dinners, the travellers they could it is in position activate second foods-clock in action and helps the organisms jet lag they are exceeded more fast. How we make him this? Saper proposes: “? A period of fast with foods in all for roughly 16 hours they are enough in order to they move this new    Therefore, in this case, simply avoiding each inmate in the plane, and afterwards it eats hardly ground, it should you it helps it is adapted - and it avoids certain from the unpleasant sentiments jet lag”, it adds.
