Research in the Origin of Microtubules

...this was impossible before the advent of live-cell imaging techniques that could reveal the true origins of these structures. "The Golgi apparatus is very close to the centrosome," said Kaverina. "So if you're not looking at it precisely, it is hard to distinguish between the centrosome and Golgi." To get ...

Researchers Link Bacteria Destroying Proteins to Alzheimer's Treatment

...lead to their death. The scientists are also using imaging and biochemical techniques to see, in cultured cells, how the antibodies affect the clusters. "We have many indications that antibodies work. Now we need to understand how they do it," Gouras said. The study appears in the June 29 issue of the Jour...

Talking About Your Feelings Really Does Help

...y Dr Matthew D. Lieberman, conducted the new brain imaging study. When people see a photograph of an angry or fearful face, they have increased activity in a region of the brain called the amygdala, which serves as an alarm to activate a cascade of biological systems to protect the body in times of danger. ...

Meditation Increases Attention - A Brain Scan Report

...itate, all subjects underwent a magnetic resonance imaging scan of the brain while they were meditating. Among all experienced meditators, the MRI scan found greater activity in brain circuits involved in paying attention. "We found that regions of the brain that are intimately involved in the control an...

Radio-frequency Ablation Offers Hope for People With Inoperable Kidney Tumours

...blation needle into the centre of the tumour using imaging techniques such as ultrasound or CT scan. The probe is connected to a radio-frequency generator that delivers alternating electrical current to the tumour producing heat up to 140 degrees Fahrenheit. This causes cancerous cells to shrink and die, but...

New Imaging Technique may Help Detect Multiple Sclerosis Early

Purdue University researchers say that new imaging technique, called coherent anti-Stokes Raman cattering microscopy (CARS), can be helpful in early detection of multiple sclerosis. The researchers have studied and recorded how myelin degrades real-time in live mice using the technique. M...

Autistic Individuals can Be 'trained' to Comprehend Visual and Vocal Cues
