Spanish scientists have revolutionized medicine with a brain transplant, triggering the vision of a blind woman who was allowed to “see” for the first time in 16 years.

The surgeon allowed the patient to see the light and patterns again, directing the light in front of them using a “synthetic retina” attached to a pair of glasses. Light processing occurred in electrical signals. The signals are then sent to an array of tiny electrodes fitted to the patient’s brain, allowing the user to “see” the light captured by the glasses.

The system was tested on a 57-year-old woman who had not seen anything for 16 years and at the time she was completely blind.

The advanced implant helped the woman to identify the patterns and images detected by the artificial retina.

“We continued to receive high-quality recordings from visually impaired neurons and the stimulus parameters remained stable over time,” the scientists wrote in a research paper published in The Journal of Clinical Investigation.

According to the scientist, the patient was able to identify “certain characters” and “boundaries of an object”.

This process is said to be completely safe. The team said that the area of ​​the brain surrounding the visual cortex would not be affected because the electrodes were attached to the patient’s brain.

The artificial retina does not reflect non-target neurons. This means that the system is safe to use and not as annoying as brain implants.

This system requires a relatively low level of electrical activity compared to other neural sequences of implants.

Six months later the artificial retina was removed from the woman’s brain.

Although more research is needed before the technology can be widely used, the initial indications are promising.

This could be a major improvement in low vision correction, which is an improvement in this field.

But this is not the first time a blind patient has been treated with a revolutionary technique to restore vision.

In May 2021, a partially blind man regained his sight after a gene therapy that used pulses of light to control the activity of neurons.

This is the first successful demonstration of what is known as ophthalmic therapy in humans. This method involves the use of ophthalmogenics as a medical treatment, which involves the conversion of electrical signals into neurons in a fire when exposed to wavelengths of light.

This gives neuroscientists the ability to accurately control neural signals in the brain and elsewhere.

After trying it…new anti-obesity drug alert



After trying it…new anti-obesity drug alert

However, Pfizer announced its intention to develop a modified version of the drug “Danoglipron”.

This drug belongs to a new class of successful treatments based on a component such as the gastrointestinal hormone glucagon or GLP-1 (GLP-1).GLP-1This leads to a feeling of fullness and weight loss.

“Danoglibron” differs from competing drugs already on the market in that it is not given by injection, but is given orally in the form of tablets.

During the clinical trial, Pfizer tested taking these pills twice a day, but said it wanted to focus on a new once-a-day formulation.

The clinical trial included a few hundred obese participants without type 2 diabetes.

Pfizer explained that the side effects in this trial were similar to those that can occur with this type of drug, but “it is noteworthy that their rates were high” because “cases of nausea reached 73 percent, vomiting reached 47 percent, and diarrhea reached 25 percent.”

More than half of the participants who received this drug discontinued treatment.

However, “Danoglipro” has been shown to lead to weight loss between 8 percent and 13 percent over 32 weeks or between 5 percent and 9.5 percent over 26 weeks.

A report quoted Pfizer senior executive Michael Tolston as confirming that “an improved once-daily formulation of tanoglipron could play an important role in the treatment of obesity.”

The highly lucrative anti-obesity drug market is currently dominated by the Danish “Novo Nordisk” group with its drug “Vecovi” and the American “Eli Lilly” company “Zebound”. America last month.
