Effects Of Total Intravenous Anesthesia Vs Sevoflurane Anesthesia

Researchers evaluated that the incidence of ED in children who underwent full mouth dental rehabilitation under either sevoflurane (SEVO) anesthesia or propofol-based total intravenous anesthesia (TIVA). Pediatric dental procedures are performed under anesthesia because children may be uncooperative in the dental clinic due to their young age.

Emergence delirium (ED), which involves a variety of behavioral disturbances that are frequently observed in children following emergence from general anesthesia, remains an unclear phenomenon.

Astronaut Gets Sick In Space

Astronauts are among the fittest and healthiest people in the world. They are rigorously trained, vetted, and quarantined before they’re allowed up in space and yet, despite all those precautions, they do sometimes get sick.

And because space missions are on a strict schedule planned far in advance, sick astronauts on a space mission can't just pop down to Earth to see a doctor. But when astronauts fall ill, they don't have to worry NASA and other space agencies that have missions aboard the ISS are prepared.

New Method For The Effectiveness Of Neurodegeneration

Researchers have developed a new and improved method to judge the effectiveness of experimental therapies for neurodegeneration the progressive loss of neurons. Neurons or nerve cells are hugely important to our daily lives.

These specialized cells collect and process the large amounts of information that enter our bodies via our senses, control our muscles and organs, and form our thoughts and memories. When these cells become unhealthy, it leads to diseases like Alzheimer's and Parkinson's, ALS, glaucoma and chronic pain.  The study was published in PLOS ONE. Johnstone says his study uses the first automated test specifically designed for measuring degeneration of sensory neurons grown in a lab.

Destructive Mechanism Blocks The Brain Enzyme Functioning

Researchers have uncovered a destructive mechanism at the molecular level that causes a well-known phenomenon associated with obesity: leptin resistance. They found that mice fed a high-fat diet produce an enzyme named MMP-2 that clips receptors for the hormone leptin from the surface of neuronal cells in the hypothalamus. This blocks leptin from binding to its receptors. This, in turn, keeps the neurons from signaling that your stomach is full and you should stop eating.
