Researchers have succeeded in neutralizing the energy source of the deadly glioblastoma brain cancer tumor, thereby causing its disappearance

  • 8 תגובות
In the experiments conducted on mice, it was found that in the presence of the energy source (brain cells called astrocytes) the tumor was 100% fatal, and all the animals that got sick died within 4-5 weeks from the moment of its appearance. When the researchers eliminated the astrocytes, within a few days of starting the treatment, the tumor died and disappeared * A new method for curing one of the most violent types of cancer and other brain tumors

The presence of certain bacteria in saliva may indicate post-trauma among veterans

  • 3 תגובות
As part of the study, the researchers characterized the psychological, social and medical condition of approximately 200 veterans and at the same time collected saliva samples from them. The research findings show that all those soldiers who suffered from post-traumatic stress disorder have a typical picture of bacteria in their saliva. A third of them were not diagnosed

A small molecule that will make the immunological treatment of cancer accessible to all patients

Prof. Ronit Sachi-Painero: "I believe that in the future the small molecule will be available and will make immunological treatment accessible and effective for cancer patients."

Store managers received financial incentives to promote tobacco products

A study by the Hebrew University found that the tobacco companies offer benefits and gifts to store owners to market their product in a prominent location and in a more beautiful display, and teach them how to circumvent the legislation that prohibits the advertising and display of the products

A fast, accurate and cost-effective method for detecting cancer-causing mutations

  • No comments
The new technology we developed provides accurate data on the nature of the mutation based on the RNA sequencing of the tumor only - that is, without the need for DNA sequencing of the tumor and any sequencing of the healthy tissue

The state of California is promoting an initiative for self-production of insulin

  • No comments
The state of California promotes programs for self-production of insulin. The governor of California, Gavin Newsom, allocated one hundred million dollars from the new state budget for this purpose. The governor is known for his position, ever since his election in 2019, which supports the self-production of generic drugs

Through genetic manipulation: researchers succeeded in preventing degenerative joint disease

As soon as the disease develops, significant damage has already occurred that cannot be cured, but the development of a unique genetic strain allowed the university researchers to stop the pain and erosion. The findings can predict the disease after joint trauma and start critical medical treatment

Researchers were able to produce the biological substance melanin for the first time under laboratory conditions

  • 5 תגובות
The results of the research by a team led by female researchers from Tel Aviv University showed that with the help of the new technology that the researchers developed, it is possible to control the production process of melanin in the laboratory, and obtain a pigment similar in its properties to biological melanin

"Thanks" to cannabis research: researchers have identified the development process of diabetic kidney disease

In this disease, the body produces substances similar to those found in cannabis, which damage the kidney * University researchers have found a way to improve the medical treatment of diabetic kidney disease, which affects approximately 30% of diabetics in the world. The new method that is adapted to each patient can prevent the damage, and even the development of the disease

The colors you see are due to the porosity of the surface - nanoholes that refract and absorb the different wavelengths of light in an inhomogeneous manner, which causes the different colors of the rainbow to appear.

New technology offers treatment for the HIV virus through an injection. As part of the research, the researchers succeeded for the first time in the world in engineering type B white blood cells inside the patient's body, so that they secrete antibodies to AIDS. The research was conducted on model animals with great success. All the model animals that received the treatment responded to the injection and had high amounts of the AIDS neutralizing antibody in their blood

A conceptual illustration of the chess battle between the cancer cells and the anti-cancer drugs. Most cancer deaths are related to the development of drug resistance and the formation of metastases. In both processes, the cancer cells face difficult and new challenges and a strain: finding a bypass for the drug, or a way to adapt to a foreign and hostile tissue. Unfortunately, the cells often manage to overcome these challenges. How does this happen? This is a complex process, and among other things, the cells go through a process of learning, which involves trial and error, while searching among a large number of configurations and internal states. The theory of learning theory constitutes a mental and mathematical framework for understanding these processes. A review of the current literature shows that basic concepts of learning theory provide an explanation for results that do not correspond to the popular concept. Linking the search process to a concrete mathematical model demonstrates its feasibility. (Illustration: Harel Spring)
