It proved that general anesthesia is harmful to the brain
Surgical interventions that involve prolonged use of anesthesia may cause unpleasant consequences. According to The Daily Mail, some brain damages were observed in patients under general anesthesia. And their effect persists for up to five days. British scientists have tested the effect produced by oxygen starvation (the result of anesthesia and insufficient oxygen supply during surgery).
A new drug gives patients with tuberculosis a hope.
Accordint to "Remedium", "Infectex" company has successfully carried out clinical studies of SQ109 preparation in patients with pulmonary tuberculosis with multiple drug-resistant pathogens. So, after half a year of experimental therapy, the incidence of bacterial overgrowth has increased up to 80% compared with standard therapy plus placebo (61%).
Insulin spray will help the people with cognitive impairment
There are more evidences that insulin performs a number of important functions in the brain. In the course of research, an insulin resistance, its decreased level in the cerebrospinal fluid and disturbed transmission of insulin signals in the brain were revealed in people suffering from Alzheimer's disease. Specialists from the University of Rush have suggested that apparently, an insulin spray will positively affect the cognitive functions in these people.
