Biophysics congress: Stay-away hosts

Stay Away From Self: 5th International Congress on Autoimmunity, Sorrento, Italy, November 29–December 3, 2006

If T cells can be regulatory, why not B cells? This proposition has piqued the interest of Sudhir Gupta (University of California, Irvine, CA) since regulatory T cells were first identified. A growing body of evidence now supports the existence of regulatory B cells (B regs), and Gupta’s presentation provided the first data suggesting their existence in humans. Previous studies of mouse models ...

Memory of gender and gait direction from biological motion: gender fades away but directions stay.

The delayed discrimination methodology has been used to demonstrate a high-fidelity nondecaying visual short-term memory (VSTM) for so-called preattentive basic features. In the current Study, I show that the nondecaying high VSTM precision is not restricted to basic features by using the same method to measure memory precision for gait direction and gender-stereotypical gait patterns from high...

Ultrasound-guided regional anesthesia: why can't we all just stay away from the nerve?

To the Editor:—I read, with interest, the case report describing a brachial plexopathy after an ultrasound-guided interscalene block in a patient with multiple sclerosis and the accompanying editorial and would like to make an observation not mentioned in either. Interscalene blocks have been performed using either mechanical paresthesia or electrical nerve stimulation, for decades, with succes...
