Solved, the puzzles about the HIV spreading in the body!

Scientists have long known that the Human Immunodeficiency Virus (HIV) attacks the human CD4 T cells, lowered immunity, triggering Acute Immunodeficiency Syndrome (AIDS). However, the pattern of spread of the virus is still a puzzle.

Trying to solve the puzzle, a HIV expert at the same network security of University College London, Changwang Zhang, develop simulation. The model is inspired from the Conficker virus infection in the military and police Europe's first in 2008.

The simulation results show that the spread of HIV in the body similar to the pattern of spread of Conficker. "Both use a hybrid mechanism, survive for long, and difficult to remove," said Zhang.

To enter into a network, Conficker has two main lines, namely between computers directly and via the Internet. HIV also has two lines, namely through the blood and direct inter-cell. "The model that we have developed to explain important features to predict the infection process," Zhang said as quoted by the Daily Mail on Tuesday, April 7, 2015. Zhang added, the model will help the fight against two viruses of computer and biological.

The model was inspired by similarities between HIV and computer worms such as the highly damaging 'Conficker' worm, first detected in 2008, which has infected military and police computer networks across Europe and is still active today. (Picture from: http://dailym.ai/1FDzfWb)

For confirms the modeling, Zhang examined 17 HIV-positive patients in London. As a result, a hybrid deployment model is most appropriate to describe the condition in these patients. HIV-related, because it is known as a hybrid spread, the spread between cells directly can not be underestimated. In fact, the pattern of spread of the possibility that a greater role accelerate the progression of HIV to AIDS.

Benny Chain, a scientist at University College London who participated in the research says, "The amount of HIV in the blood stream is always lower and our models indicate that HIV in the blood alone will not be able to cause AIDS."

"Most likely HIV hiding place had high T cell populations, such as the gastrointestinal tract, and then use the mechanism for inter-cell spread efficiently," he added. The presence of HIV is hiding in the T cell-rich areas show the need for the use of antiretroviral drugs immediately. Because, what if so infected with HIV live in hiding in those places?

"Our models indicate that blocking the spread between cells will prevent the progression of HIV to AIDS, underscoring the need for new treatment method," said Chain. Going forward, Chan and Zhang plan to study the direct spread of the virus similar to HIV in the animals. *** [EKA | FROM VARIOUS SOURCES | DAILYMAIL]

The figure of India's first supercar

Mean Metal Motors (MMM) is a newly established automotive company and reportedly developing an India's first supercar named 'M-Zero'. This local company brags that their supercar is able to compete with the German rivals in the same segment.

In addition to having a unique design, MMM will equip this supercar with a lightweight carbon fiber construction. Now for the machine will reportedly use a V8 engine that has a capacity of 4.0 liters and rely on the supplies from AMG, an official Mercedes-Benz home modifications. Although, the supply of these machines are still in the planning and Mercedes-Benz are not necessarily want to give it away.

The design looks still stiff and seem amateurish. (Picture from: http://bit.ly/1ImreIT)

However, for the supply of engines could switch to other supercar manufacturers, such as Pagani or Aston Martin. Although still underestimated, but India's first super car project is quite realistic. In addition, MMM will also have the option to equip the M-Zero with parallel hybrid technology that is capable of producing a total of power up to 800 hp (500 of which is from the combustion engine).

The plan, this supercar will be produced in one of the Scandinavian countries after the company got the investments worth of U.S. $7 million. M-Zero will target the affluent consumers in Europe, and compete with other rivals in the same segment. The ideas and creations of the Indian young generations deserves appreciation. *** [EKA | FROM VARIOUS SOURCES | CARSCOOP]

Chileans Bumblebee replica

Bumblebee, an Autobot character in the Transformers movie was still seized the attention of the world community. If in China there are farmers and citizens who make replicas of the Transformer robots (jump to the article), then in Chile there is a car that can actually be transformed into Bumblebee robot like in the movie.

As quoted from Autoevolution on Wednesday, April 8, 2015, in the Hualpen, Chile, there is a replica of the Chevrolet Camaro car that mechanically controlled so that it can turn into Bumblebee figure. Video of the Chileans Bumblebee had been uploaded on Youtube.

Although the replica, the Camaro cars made approaching its original form, starting from the body, the use of lights and front grille, yellow paint with black stripping from the hood to the trunk, as well as the shape of the rims and wheels. Unfortunately, no detailed data regarding the car specs including using the base of any vehicle.

From the pictures look, two large telescopic spring used to support the car body when standing. While on the left and right doors mounted smaller telescopic spring, so that when the car to change shape can be seen resemble the Bumblebee's hands. The car can run slowly both before and after the change. 

While it might not be perfect, it’s the best replica we’ve seen so far of the popular robot. Not bad at all, that's the creative ideas from some of Bumblebee fans in Chile. Well, now try to compare to those made in Chicago, there are similar or not?

For information, the Chevrolet Camaro was marketed with two engine options, the first was V6 3,600cc engine that capable of spraying power of 323 hp and the second was V8 6,200cc engine powered 580 hp. The transmission also offered in two options namely six-speed automatic or six-speed manual. *** [EKA | FROM VARIOUS SOURCES | AUTOEVOLUTION]

Death can be postponed?

During this time, many people believe that the death triggered by heart stopped beating so pumping blood throughout the body stops and eventually the body stops working. However, a recent study by experts from the University of Michigan nerve, Jimo Borjigin, reveal that death is determined by the signal submissions to the heart of the brain rather than the heart organ itself.

"People usually focus on the heart, thinking that if it saves the heart, the brain will also survive. You have to decide chemical communication between the brain and the heart to save the heart," said Borjigin.

Near death the brain releases signals that speed up heart demise. (Picture from: http://bit.ly/1Dig9FG)

To reveal it, Borjigin exposing rats to carbon dioxide, induces arrest incident heartbeat. Towards death, scientists observed the activity of the heart by echocardiography (ECG) and electroencephalography (EEG) and chemical signals in the two organs.

Borjigin reveal, after exposure to carbon dioxide, rat heart rate went down. Then, the activity of the brain adapts to the activity of the heart. At that time, compounds that trigger relaxation dopamine, and norepinephrine that trigger alertness, blood flooded.

Having sent two compounds that function as a signal that keeps the heart in rhythm with the lower chambers of the brain until the heart can not contract normally to pump blood. The condition is called ventricular fibrillation.

Ventricular fibrillation condition lead to death. When scientists inhibit the delivery of dopamine and norepinephrine, ventricular fibrillation condition can be inhibited. Finally, the death can be postponed. What can be done the same way in humans to delay death? Borjigin, as reported Livecscience on Tuesday, April 7, 2015, said, "It's a question worth billions of dollars."

Research to realize it would be very valuable. This is not to meet the desires of those who do not want to die, but to save the lives of people who had stopped heartbeat. By blocking signals from the brain, doctors have more time to save the patient. *** [EKA | FROM VARIOUS SOURCES | LIVESCIENCE]

The LM2 Streamliner is designed to have a carbon fiber body and full length carbon fiber chassis, with carbon fiber and billet stainless steel subframes. The suspension of titanium and aluminum billet present in the Luxury and Sport settings that can be adjusted its drive quality. To reduce the speed of the car is then mounted Brembo's carbon ceramic brakes.

LM2 Streamliner does not have door handles, however, this car provides sufficient capacitive touch sensor to open and close the door. Rearview mirror has been replaced with a camera that displays the condition in outside the car with very clear. Front and rear lights are also LEDs supported. The electric versions of cars is also in the planning.

If you want to see the LM2 Streamliner prototype, then visit the New York International Auto Show 2015 which lasted on April 3 to 12, 2015. Can Lyons' 1700 Horsepower Supercar become a reality?. *** [EKA | FROM VARIOUS SOURCES | LYON MOTOR CAR | GIZMAG | CARSCOOP]

This is the first person who will undergo the human head transplant operations

A man from Russia recently made a startling announcement after stating his willingness to volunteer in the trial of human head transplant operation, on Wednesday, April 8, 2015.

As reported by the Mirror, Valery Spiridonov (30) a computer scientist who suffer from abnormalities in the muscles, so that his muscle growth is not normal and is hoping to be the first to perform a head transplant would be led by Dr. Sergio Canavero.

This Russian man is very confident with his decision, because he suffered a muscle disorder also known as Werdnig-Hoffman syndrome, is potentially fatal. 

"My decision was unanimous and there was no room to change my mind, what I fear? Of course, it looks terrible but on one hand it is very interesting to try, if I did not take this decision then bad things will happen to me as well," he said.

Meanwhile Dr. Canavero told CNN, saying that he made sure Spiridonov will be the first to do the head transplant, but still constrained in terms of funding and has not met directly with Spiridonov for medical track record. 

Dr. Canavero also said besides Spiridonov also there are some other people who has declared their readiness to become a volunteer in this large project, but everything is still limited through the e-mails.

To do this big project Dr. Canavero has prepared 150 doctors and nurses. Dr. Canavero very confident that he is able to do so and is expected to take as long as 36 hours for the head of the transplant surgery.

As an illustration, in 1970 a head transplant operation ever conducted on monkeys, but after eight days the monkeys died because because the body rejected the new head. And before the monkey dies, it can not move because the spinal cord of the head and body are not perfectly connected, it also had difficulty breathing.

This of course will lead to controversy, as expressed by Arthur Caplan, director of medical ethics at New York University’s Langone Medical Centre, has described Dr Canavero as 'nuts'.

He said the bodies of head transplant patients 'would end up being overwhelmed with different pathways and chemistry than they are used to and they’d go crazy.' He added: “It’s not like you can unscrew your head and put it on someone else.”

Dr Hunt Batjer, president elect of the American Association for Neurological Surgeons, added: “I would not wish this on anyone. “I would not allow anyone to do it to me as there are a lot of things worse than death.”. *** [EKA | FROM VARIOUS SOURCES | MIRROR]
