TO THE EDITOR: I am writing to express some concerns about the article by Stämpfli et al. (7), “Experimental determination of net protein charge, [A]tot, and Ka of nonvolatile buffers in bird plasma.” First, it appears that the BCG dye binding technique was used to determine albumin concentration. This technique has not been validated for avian albumin and does not correlate with electrophoreti...

OBJECTIVE To restore accommodation in primate eyes by refilling the lens capsule with injectable silicone compounds. MATERIALS AND METHODS Eight eyes of 8 monkeys (Macaca fascicularis) were treated by the lens refilling procedure. To prevent leakage of the injected liquid silicone before it polymerized in the capsule in vivo, a silicone plug for sealing the capsular opening was developed. Aft...

Editorial Global Navigation Satellite System (GNSS) remote sensing comprises GNSS reflectometry (GNSS-R) and GNSS refractometry (also known as GNSS radio occultation or GNSS-RO). GNSS-R involves analyzing measurements of GNSS signals reflected from the Earth's surface, while GNSS-RO utilizes measurements of GNSS signals refracted by the atmosphere, when the slanted propagation path is close to ...
