If You are HIV Positive, Take Your Medications Can Prevent You From Spreading To Other
Since the discovery of HIV / AIDS, the scientific community continues to investigate to find a cure and prevent disease transmission. Recently it was discovered that further antiretroviral therapy (ART) can prevent the spread of HIV between partners and from mother to child.
The so-called HIV (Human Immunodeficiency Virus) is a viral disease with no cure. However, there are now treatments that can maintain a good quality of life in sufferers. There are many patients who can demonstrate this. Santiago is one of them when he learned he was HIV positive was depressed a lot, “was the end of the world, I thought I would die in a month,” recalls between smiling and sad, because that was more than 20 years now looks healthy and energetic, he was always very active and the disease does not prevent him from continuing with their many projects.
At first glance, today nobody notices that James is HIV positive, in confidence unless he tells her experience, their fears and sometimes it was changing its treatment. The latter was important for your health, and new discoveries now found drugs and methods that may help prevent infection from their partners and from mother to child. For example, a study by researchers from Africa and the United States, published in the journal Lancet, found that HIV patients who continued antiretroviral therapy (ART) were much less likely to infect their partners.
ART therapy involves taking a combination of drugs that reduce the amount of HIV virus in the blood of an infected person and increases the body’s defenses (the number of CD4 cells) at six months of starting therapy. Specifically, taking the drug combination reduced the likelihood of HIV transmission by 92% of cases.
While this type of treatment for HIV exists since 1996 and changed the way of treating HIV patients, allowing them to extend and improve their quality of life was not yet known to what extent the ART therapy reduced the risk of transmission.
However, this finding corroborates and reinforces the importance of receiving and making appropriate treatment, once you are diagnosed / or HIV. Thus, not only can reduce the presence of virus in your blood but also the possibility of infecting your partner or, if you’re pregnant, your baby.
Worldwide efforts are made to the prevention and treatment of HIV. This is the case of UNICEF (the United Nations Fund for Children), which recently created a new method for distributing drugs to 30,000 pregnant women in different African countries, with this expected to reduce the numbers of infection. In this case there is a great scientific discovery but a color-coded package containing drugs against HIV.
Specialists are based on the idea that in many cases the prevention and treatment of HIV / AIDS depends on social issues rather than medical. Proper dissemination of information and provide access to needed medicines can help prevent and treat disease and to give them every tool possible to patients for each treatment can continue properly according to their condition.
If you suffer from HIV, do not hesitate to go to a specialist clinic. Learn about the different treatments you can follow to maintain good quality of life, protect yourself and protect others. Similarly, if you think you can be infected, be encouraged to make the studies to be aware of your body and your health and to take steps either to fight HIV or prevent it.
As in the case of Santiago, the following antiretroviral therapy can cause the levels of virus in your blood are so low that hardly detected. Is not it wonderful? That way you’re watching your health and that of those who want as your partner or your baby.
What Makes A Probiotic?
The requirements for a microbe is considered a probiotic are simple. The microbe must be alive when administered, must be documented to have a health benefit and should be administered at levels shown to confer the benefit.
A report on “Guidelines for the Evaluation of Probiotics in Food” is more complete than minimum charges probiotic experienced a necessity.
The results were:
* The Probiotics must be identified in the genus, species and strain level, using appropriate molecular and physiological techniques. Read the rest of this entry »

Lactulose is a synthetic carbohydrate prebiotic composed of natural sugars fructose and galactose.
Lactulose is the ideal nutrient for microorganisms beneficial to health, ie bifidobacteria and lactobacilli, and serves to stabilize and recover our physiological intestinal flora.
In nature, prebiotics found in vegetables such as garlic, asparagus or onions, and also in foods like yogurt and milk.
What is the role of lactulose?
In addition to exercising a prebiotic effect, ie to stabilize the physiological intestinal flora, lactulose is also indicated to treat constipation (medical term: obstipation). Before being absorbed by the intestinal bacteria, lactulose exerts an osmotic effect: introducing water into the intestinal lumen and thus increases the volume of stool. In turn, this stimulates the muscles of the intestine and promotes bowel movements. Read the rest of this entry »

Unlike probiotics, ie live microorganisms, prebiotics are non-digestible carbohydrates. These prebiotics stimulate the growth and activity of batteries beneficial intestinal flora. One of the best non-digestible carbohydrate lactulose is investigated. Lactulose is, as such, a prebiotic.
What is the human intestinal flora?
The intestine of an adult contains approximately 1014 bacteria, divided into more than 400 species and subspecies than reaching a weight of 1 to 1.5 kg.
Bacteria, being unicellular organisms, have the ability to run by themselves all the vital metabolism, so that the intestinal flora can be considered as a large and complex body metabolising body. Therefore, this “body” influences on our health and wellbeing. Read the rest of this entry »

Gastritis is a common disease suffered by many people in certain circumstances. It is characterized by an unbearable burning sensation in the stomach, and suffer recurring heartburn. It is also very common for the person suffering from gastritis to suffer dizziness and nausea.
This disease is an inflammation of the gastric chamber, resulting in a reddening of the gastric mucosa. It is caused by abuse of alcohol and painkillers, but is also produced by infection with the bacterium Helicobacter pylori.

The Ebola Virus (part 2)
Treatment
The Ebola virus, like all viruses “hot”, no cure and no specific treatment. The treatment used today is to maintain the life of the person by methods of resuscitation (CPR, artificial respiration) and control bleeding as far as possible.
As for a vaccine, investigations are underway but these are complicated because we still do not know all the proteins of the virus and because there are only 2 or three laboratories equipped to work with a virus such as these.
These laboratories are located in the U.S. and Russia, and the best known are the CDC (Centers for Disease Control) in Atlanta, Georgia, and USAMRIID (United Estates Infectius Army Medical Research of Diseases, Research Center for Infectious Diseases Army U.S. rough translation).

The Ebola virus is the most deadly filoviruses known. The family of filoviruses (filamentous virus) includes the four classes of Marburg and Ebola viruses. These 4 types (or strains) are called Ebola Zaire, Ebola Sudan, Ebola Reston and Ebola Tai Forest (Ebola Ivory Coast). The worst is the Zaire Ebola kills nine in ten people infected. Sudan remains the strain with a mortality rate of 60%. It is unclear whether the latest strains cause human deaths (not killed any humans). This virus was discovered in Africa . It takes its name from the Ebola River in the current DRC (then Zaire).
The Ebola virus is responsible for an acute febrile illness, severe and often very deadly affects humans and primates. It produces a hemorrhagic fever similar characteristics to Argentina hemorrhagic fever (Junin virus). Is called hemorrhagic fever because it presents with high fever associated with generalized bleeding. Read the rest of this entry »

8. The main goal of biologists has been the molecular study of viruses and their interaction with the host cell. The study of bacteriophage replication in bacteria discovered the existence of messenger RNA, carrying the genetic code of DNA needed for protein synthesis. Studies with these viruses have also been instrumental in defining the biochemical factors that start and end the use of genetic information. Knowledge of the mechanisms of control of viral replication is critical to understanding the biochemical events in higher organisms.
The viruses are useful as model systems for studying the mechanisms that control genetic information, because in essence are small pieces of information. This allows scientists to study replication systems simpler and more manageable, but that function on the same principles as those of the host cell. Much of the research on the virus replicative pretends to know the mechanism to find and how to control growth and eliminate viral diseases. Studies on viral diseases have greatly contributed to understanding the body’s immune response against infectious agents. Studying this response have been thoroughly described serum antibodies and the secretions of mucous membranes, which help the body eliminate foreign elements such as viruses. Now, the scientific interest is focused on research designed to isolate certain viral genes. They could clone to produce large quantities of certain proteins, which would be used as vaccines.

5. Propagation
Viruses are spread from person to person, causing new cases of the disease. Many of them, as those responsible for influenza and measles, are transmitted by inhalation, through its dissemination in the infected droplets emitted by coughing and sneezing. Others, like those that cause diarrhea are spread by fecal-oral route. In other cases, the spread is through the bite of insects, such as yellow fever and arboviruses. Viral diseases may be endemic (specific to one area), affecting susceptible individuals, or epidemic, which appear in waves and attack much of the population. An example is the emergence of epidemic flu worldwide, almost always once a year.
6. Treatment
The treatments against viral infections are often not entirely satisfactory, since most of the drugs that kill viruses also affect cells in which they play. The alpha-adamantanamine is used in some countries to treat respiratory infections caused by influenza A and isatin-beta-thiosemicarbazone, effective against smallpox. Certain substances similar to precursors of nucleic acids may be useful against severe herpes infections. Read the rest of this entry »

3. Replication
The virus, lacking the enzymes and metabolic precursors necessary for its own replication, they must obtain them from the host cell they infect. Viral replication is a process that includes several separate synthesis and subsequent assembly of all components to give rise to new infectious particles. Replication is initiated when the virus enters the cell: cellular enzymes remove the cover and the DNA or RNA is contacted with the ribosome, directing the synthesis of proteins. The virus nucleic acid autoduplicates and, once synthesized protein subunits that form the capsid, the resulting components are assembled into new viruses. A single virus particle can cause a progeny of thousands. Some viruses are released by destroying the infected cell, and yet leave the cell without destroying it by a process of exocytosis that leverages own cell membranes. In some cases the infection is ‘silent’, ie the viruses replicate inside the cell without evident harm.
RNA-containing viruses are unique replicative systems, since the RNA autoduplicates without the involvement of DNA. In some cases, viral RNA functions as messenger RNA, and replicates indirectly using the ribosomal system and the metabolic precursors of the host cell. In others, the virus carried in the cover-dependent RNA enzyme that directs the synthesis process. Other RNA viruses, retroviruses, may produce an enzyme that synthesizes DNA from RNA. Formed DNA then acts as the viral genetic material. Read the rest of this entry »
