Scientists determine the cause of the development of Alzheimer’s disease in the brain

العلماء يحددون سبب تطور مرض ألزهايمر في الدماغ

Scientists have identified the cause of the development of Alzheimer’s disease in the brain, raising hopes that new therapies could be developed to target the disease.

An international team of researchers led by the University of Cambridge found that instead of spreading like cancer from one source, clusters of toxic protein slowly accumulated in many parts of the brain at once.

These clusters develop over many years and are called clusters, and they cause cell death and brain contraction, leading to memory loss, personality changes, and difficulty performing daily activities.

In a study published in the journal Science Advances, the rate of development of Alzheimer’s disease was determined by recurrences in individual brain regions, not by clusters that spread from one area to another.

How quickly these groups kill brain cells determines the rate of overall decline in brain function.

Two types of proteins, called dove and amyloid-beta, work together to create the problem.

The scientists used autopsy brain samples and scans from living patients, including those with mild cognitive impairment and those with late blight, to monitor Dow build-up.

Dow found that the response to aggregates was surprisingly slow, lasting up to five years.

David Kleinman, associate professor of dementia research at the UK’s Institute for Dementia Research at the University of Cambridge, said: “Neurons are surprisingly good at preventing problems, but we need to find ways to make them even better if we are to develop an effective treatment.”

Researchers say their findings could help develop treatments for Alzheimer’s disease, which affects about 44 million people worldwide, targeting the most important processes that occur when humans get sick.

Professor Thomas Knowles, co-senior author of the Department of Chemistry at Youssef Hamid in Cambridge, noted: “The key finding is that stopping mass copying would be more effective in the disease stages we have studied than in their reproduction.”

Researchers now plan to look at past processes in the development of Alzheimer’s disease, and expand the study to include other brain diseases, where excessive exposure to Dow protein plays a key role in improving the condition.

Commenting on the study, Dr. Sarah Emericio, UK research head at Alzheimer’s Research, said: “We hope that this study and other future therapies like this will help focus on developing Dow, so that future treatments have a better chance of slowing down, including those with dementia. The processes of the disease benefit others.

What are the most common symptoms of breast cancer in men?

What are the most common symptoms of breast cancer in men?

Breast cancer is a disease that affects women, especially with a high number of infections, but in fact it affects men as well, and many believe that it leads to death among them.

she explained NHS The NHS in England says that 85 men die each year in Britain from breast cancer, and that the malignancy affects around 400 men annually.

The charity Breast Cancer Now also reports that “at least one person is diagnosed with the disease every day”.

According to the website “Mayo ClinicMedically, male breast cancer is “a rare cancer that begins with the growth of cells in the breast tissue of men.”

Breast cancer cells disrupt the immune system

Australian researchers announced Monday that breast cancer cells have powerfully destroyed the body’s immune system, allowing the disease to invade patients’ bones.

“Breast cancer in men usually affects older people, but it can occur at any age,” he pointed out.

Those diagnosed with “male breast cancer” at an early stage have a good chance of recovery.

What are the symptoms?

The symptoms of this disease are as follows:

A painless lump or thickening of breast tissue and changes in the skin of the breast, such as sagging, wrinkling, redness or peeling.
Changes in the nipples, such as redness or peeling, or one of the nipples turning inward.

The causes of these malignant tumors are still unclear, but doctors define “male breast cancer” as occurring when “some breast cells divide faster than healthy cells.”

Accumulated cells form a tumor, which can spread (metastasize) to nearby tissues, lymph nodes, or other parts of the body.

According to the website “Web MedicineThe disease can be diagnosed through a clinical examination, which is done by feeling the chest area of ​​the person in search of any tumors or changes in the chest tissue, and the doctor evaluates the size, structure and depth of the tumors present.

It can be diagnosed with radiographic imaging such as X-rays or ultrasound to create clear images of the breast tissue.

Only a biopsy is used to “confirm” a diagnosis of breast cancer in men. This is done by taking a sample of the tumor tissue and examining it to confirm whether the tumor is cancerous or benign.

Treatment usually involves surgery to remove as much of the visible tumor as possible, along with some of the surrounding healthy tissue.

Other treatments such as chemotherapy and radiotherapy may be recommended depending on the condition.
