In visual crowding, identification of a peripheral object is impaired by nearby objects. Recent studies have demonstrated that crowding is not limited only to interaction between low-level features or parts, as presumed by most models of crowding, but can also occur between high-level, configural representations of objects. In this study we show that the relative strength of crowding at the par...

There is psychophysical evidence that low-level priming, e.g., from oriented gratings, as well as high-level semantic priming, survives crowding. We investigated priming for global translational motion in crowded and noncrowded conditions. The results indicated that reliable motion priming occurs in the noncrowded condition, but motion priming does not survive crowding. Crowding persisted despi...

intrOdUctiOn Over the past decade, emergency department (ED) crowding has occurred and progressed. It has become a major topic of discussion at emergency medicine (EM) conferences, such as those held annually by the Society for Academic Emergency Medicine and the American College of Emergency Physicians. There has been much recent media coverage, such as the Newsweek article, “Code Blue for the...

Crowding is a form of lateral interaction in which flanking items interfere with the detection or discrimination of a target stimulus. It is believed that crowding is a property of peripheral vision only and that no crowding occurs at fixation. If these two claims are true, then there must be a change in the nature of crowding interactions across the visual field. In three different tasks, we d...

Renal cell carcinoma (RCC) is an aggressive malignancy which can metastasize to the bone. Long bones or the small bones of the limbs could be rarely the destinations for metastatic RCCs. We report two cases of metastatic RCC to the humerus bone with the initial presentation of pathological fracture. The pathologists must be aware of metastatic RCC to the arm and consider it in the differential ...

Few prospective studies have examined associations between reproductive factors and risk of renal cell cancer (RCC). The authors prospectively examined whether postmenopausal hormone (PMH) use, oral contraceptive use, parity, and other reproductive factors were associated with RCC risk among 118,219 US women in the Nurses’ Health Study. A total of 247 RCC cases were confirmed between 1976 and 2...

OBJECTIVE To determine the relative frequencies of different renal tumours in adults and to analyze the histopathologic characteristics of renal cell carcinoma and its variants in the population studied. METHODS The study was carried out at Histopathology Department, Sindh Institute of Urology and Transplantation (SIUT) from April 2004 to October 2004. All consecutive adult patients with rena...
