Researchers have recently found that it is possible to easily predict extent of violence and aggression among boys only through conducting a simple test.
In the said test, a study has been done on 17 boys of 7-9 years old and value of Testosterone and Androsterone (DHEA) hormones and that of Cortisol existing in the saliva of the said boys have been measured daily.
The results of researches have revealed that concentration of the said hormones in the sample saliva shall predict extent of violation and aggression among the said kids.
Quick and simultaneous evaluation of extent of violence among adolescences is of great importance for psychiatric and clinical treatments.
Awareness about extent of stress and study of emotional conditions of adolescences, especially during maturity period, sets a desirable model for parents and educational instructors and it causes that least hurts occur for the adolescences during said period accordingly.

The American researches intend to use 3D print technology for replacement of 75% of the skull of a patient.     
Three-dimensional printed implants may be used for restoration skull bone of the patients, suffering from cancer or those who are injured due a car accident.
“Scott Defelice”, Manager of Oxford Performance Materials emphasizes: “3D print technology has covered all sectors of orthopedic industry. The advantage of this technology refers to possibility for provision of scanned digital model of a patients’ skull and layer print of the said sensitive part by the help of a three-dimensional printer.
Precise 3D print method may be used for manufacture of tiny surfaces or those with subtle details including cellular replacement for joining bones.
This Company is regarded as one of the manufacturers and exporters of 3D print implants.   The said Company has recently obtained respective license from Food and Drug Administration of America for implanting the first 3D print skull and it is ready to perform implanting surgery on 300-400 patients whose skull has been damaged and fractured.
Researchers are working on design and manufacture of various pieces of bones of human body using 3D print technology and performing much sensitive skull implanting surgery may establish suitable grounds for such surgery on other bones accordingly.

Although researchers have tried utmost for many decays to produce AIDS vaccine,   they have not been successful yet. Most of produced vaccines are not actually usable in practice due to high complications. However, now the Canadian researchers have succeeded in development of HIV vaccine, with no side-effects.
As reported by the borderless medical site reporter, it is necessary to conduct required clinical trial   at several stages on the new HIV Vaccine. About five years are needed for completion of the said process and entrance of the said vaccine at consumption market.
Researchers emphasize that since the said vaccines will probably be used for treatment of patients in the next five years, therefore, confronting HIV/AIDS must still be focused on prevention using tested and real methods such as distribution of Condom, circumcising, prevention of transmission of HIV from mothers to neonates and presenting syringe exchange plans.
Every year 400-500 Million US Dollars are spent for research on HIV Vaccine. Most of the said cost is paid for basic researches.
In spite of all efforts made in this regard, specific shape of HIV has caused that finding the said vaccine will be difficult and expensive. Segregating HIV from other infectious diseases has caused that the said virus directly attacks white blood cells, which are responsible for body safety response and disables the said cells to control infection and to prevent infection with the said virus.
“Common” vaccines are based on a complete microorganism (virus or bacterium), which have been killed or inactivated. The said vaccines are not reliable for AIDS, which may lead to infection. Consequently, HIV trial vaccines contain certain parts of viruses, which make production of the said vaccine more sophisticated.
The base for production of the genetically modified vaccine is killed virus and it has entered at test stage.   
This new vaccine is called “-H001SAV”.
The said virus has caused death of 30,000,000 individuals all over the world. Presently, over 34,000,000 persons are infected with the said virus.
It should be noted that presently, respective medicines used for treatment of AIDS are chemical ones, which are used as anti-virus medicines. In more than 30% cases, a patient has to replace the said medicine with another one or to change its dosage due to complications of the said medicines.
Variety in kinds of HIV has made the case more complicated. Various types of HIV virus, identified all over the world, are prevalent. Presently, researchers don’t know whether this new type of vaccine may cover the case thoroughly or it may be used for a specific kind of Virus.
The most prevalent kinds of HIV are subspecies of A and C, which exist in different regions in Africa. However, most of current reactions are done on the said kind; they cover the entire genetic aspect of subspecies B, which are dominant in countries of high incomes.
