Little has been written on the challenges of conducting research in regions or countries with chronic conflict and strife. In this paper we share our experiences in conducting a population based study of chronic diseases in the occupied Palestinian territory and describe the challenges faced, some of which were unique to a conflict zone area, while others were common to low- and middle- income ...

Wireless mesh networks have the potential to provide ubiquitous high-speed Internet access at low costs. The good news is that initial deployments of WiFi meshes show the feasibility of providing ubiquitous Internet connectivity. However, their performance is far below the necessary and achievable limit. Moreover, users’ subscription in the existing meshes is dismal even though the technical ch...

We describe recent progress toward defining neuronal cell types in the mouse retina and attempt to extract lessons that may be generally useful in the mammalian brain. Achieving a comprehensive catalog of retinal cell types now appears within reach, because researchers have achieved consensus concerning two fundamental challenges. The first is accuracy-defining pure cell types rather than settl...

Pure red cell aplasia (PRCA) is a rare complication of autoimmune rheumatic diseases such as systemic lupus erythematosus (SLE). Thymoma occurs in 5–13% of patients with PRCA and in 2% of patients with SLE. The simultaneous occurrence, however, of all 3 disorders is rare. We report a patient with lupus-like disease who developed PRCA in association with a thymoma and explore the management chal...
