When two sequential targets (T1, T2) are inserted in an RSVP stream of distractors, perception of T2 is impaired at intertarget lags shorter than 700 msec. Paradoxically, this deficit disappears when T2 is presented directly after T1 (lag-1 sparing). Visser, Bischof, and Di Lollo (1999) found that lag-1 sparing occurs only when T1 and T2 are presented in the same stream. In contrast, Shih (2000...

Despite considerable overlap, the confusion hovering over the four common sparing signs can be cleared as follows: Reverse Koebner relates to sparing by physical trauma; isotopic non-response/reverse isotopic response relates to sparing over an already healed dermatosis; Renbok Phenomenon relates to sparing among two concomitant active diseases often with autoimmune etiology; anatopic phenomeno...

BACKGROUND Although the aortic valve-sparing procedure has gained popularity in recent years, it still remains challenging in patients with advanced aortic regurgitation (AR). We compared the long-term outcomes of the aortic valve-sparing procedure with the Bentall operation in patients with advanced aortic regurgitation secondary to aortic root dilatation. MATERIALS AND METHODS A retrospecti...

BACKGROUND Quality of life after laparoscopic radical prostatectomy has been a discussed issue among patients. Nerve-sparing radical prostatectomy has been shown to be superior to non-nerve-sparing radical prostatectomy in terms of potency and continence. The authors have reported their experience of laparoscopic radical prostatectomy and now developed our technique of nerve-sparing laparoscopi...

OBJECTIVE To explore middle cerebral artery (MCA) and anterior cerebral artery (ACA) blood flow responses to superimposed acute hypoxemia in growth-restricted fetuses with and without established brain-sparing flow during basal conditions. MATERIAL AND METHODS 47 term fetuses suspected of growth restriction were exposed to an oxytocin challenge test with simultaneous cardiotocography and Dopp...

During radical cystectomy (RC), the neurovascular bundles are easily removed or damaged, leading to varying rates of incontinence and erectile dysfunction. The nerve-sparing technique was developed to preserve urinary and erectile function. The adoption of laparoscopic and robot-assisted technology has improved visualization and dexterity of pelvic surgeries, thus facilitate the nerve-sparing t...
