Interleukin-2 (IL-2) is an immunoregulatory cytokine that binds sequentially to the alpha (IL-2Ralpha), beta (IL-2Rbeta), and common gamma chain (gammac) receptor subunits. Here we present the 2.8 angstrom crystal structure of a complex between human IL-2 and IL-2Ralpha, which interact in a docking mode distinct from that of other cytokine receptor complexes. IL-2Ralpha is composed of strand-sw...

Here, we uncover a mechanism for regulating the number of active presynaptic GABAB receptors (GABABRs) at nerve terminals, an important determinant of neurotransmitter release. We find that GABABRs gain access to axon terminals by lateral diffusion in the membrane. Their relative accumulation is dependent upon agonist activation and the presence of the two distinct sushi domains that are found ...

An 11-year-old boy in Hawaii passed mucus and a moving object in his stool. The object was identified as a segment of the fish tapeworm Diphyllobothrium species which is not indigenous to Hawaii. Diphyllobothrium ova were also found in the stool. The only raw fish he recalled eating in previous months were tuna sushi and lomi-lomi salmon which usually contains raw but previously frozen salmon. ...

Bugs in user input sanitation of software systems often lead to vulnerabilities. Among them many are caused by improper use of regular replacement. This paper presents a precise modeling of various semantics of regular substitution, such as the declarative, finite, greedy, and reluctant, using finite state transducers (FST). By projecting an FST to its input/output tapes, we are able to solve a...

Patients with schizophrenia are at an increased risk for the development of depression. Overlap in the symptoms and genetic risk factors between the two disorders suggests a common etiological mechanism may underlie the presentation of comorbid depression in schizophrenia. Understanding these shared mechanisms will be important in informing the development of new treatments. Rodent models are p...

fundamentally changing the course of my life and teaching me everything I know about visualization, graphics, computer science research and THE FUTURE! It has been fun and I look forward to doing my PhD in the best possible place, the lack of oceans and illegality of 'on-top-of-Jeep' riding notwithstanding. and the rest of the computational biology team at Monsanto for bringing me onto your tea...

The nonnegative matrix factorization (NMF) based collaborative filtering t e chniques h a ve a c hieved great success in product recommendations. It is well known that in NMF, the dimensions of the factor matrices have to be determined in advance. Moreover, data is growing fast; thus in some cases, the dimensions need to be changed to reduce the approximation error. The recommender systems shou...
