Nanotechnology have potential to bring about significant benefits, such as improved health, better use of natural resources & imroved quality products. Nanomaterials, nanocomposites, nanoporous materials & nanomembranes will play a growing role in materials development for the dental industry. As with all technologies, nanotechnology have potential to bring about significant benefits, such as i...

With the waiver of the Orasure Oraquick rapid human immunodeficiency virus (HIV) test in January 2003, testing for HIV infection in the United States moved from the laboratory to the clinic, the emergency room, and other outpatient settings. By now, millions of rapid HIV tests have been performed, largely by nonlaboratorians and largely outside of dedicated laboratory space. This experience has...

In this paper, we study the practice of overselling in a competitive environment where late arriving consumers value the good higher than early arriving ones but the former’s arrival is uncertain. We show that overselling is a dominant strategy for the firms. However, it can lead to a prisoners’ dilemma situation in which all firms are worse off overselling. We further show that only when deman...

Sphingosine-1-phosphate (S1P), an evolutionary conserved bioactive lipid, is essential for brain development, but might also exert detrimental effects in terminally differentiated post-mitotic neurons. Its concentration in the brain is tightly regulated by specific kinases and phosphatases, and mainly by the S1P degrading enzyme, S1P-lyase (S1PL). The role of S1P in neurons was initially studie...

There has been a recent spurt in application of platelet-rich plasma (PRP) in dermatology and aesthetic medicine. However, the details regarding use of PRP in various dermatological indications ranging from hair restoration to chronic ulcers are dispersed in literature, herein we have tried to focus all under one heading. Overall, PRP seems to be a promising therapeutic modality but the level o...

The Troponin Era The advent of the “troponin era” has its roots in the redefi nition of acute myocardial infarction (AMI) by the joint committee of European and American cardiologists in 2000.1 Troponin was identifi ed as the preferred serologic biomarker for acute coronary syndrome (ACS). Since then, troponin assays have continued to evolve with improved sensitivity and reproducibility, leadin...

Will applications like computer games finally help break down the walls of the ivory tower? Or is it simply a silly distraction, undermining the seriousness of our research field in the public view? In this article, I present my opinion. As a precaution: I believe that points of view can rarely be advanced by harmonious speeches accompanied by general nodding. Instead, a friendly but spicy disc...

In sharp contrast with the experiences of all other industrialized nations, the size of the labor force of the United States is growing rapidly while, simultaneously, its age, gender, and ethnic composition are changing markedly. Consequently, human resource issues present an unprecedented challenge in the nation's quest to achieve a fully employed and equitable society. New public policies tha...

Spam, also known as Unsolicited Commercial Email (UCE), is the bane of email communication. Many data mining researchers have addressed the problem of detecting spam, generally by treating it as a static text classification problem. True in vivo spam filtering has characteristics that make it a rich and challenging domain for data mining. Indeed, real-world datasets with these characteristics a...

We study tree level corrections to precision electroweak physics in the recently proposed Higgsless models in warped space. Such models inherit from their similarity with technicolor theories a large contribution to the oblique parameters, S in particular. We show that it is possible to suppress S using brane induced kinetic terms and unequal left-right bulk gauge couplings, paying the price of...
