Internet -- Security measures. Public key infrastructure (Computer security). Digital signatures. Peer-to-peer architecture (Computer networks) -- Security measures.
The Internet has become a virtual place where people not only operate in isolation but also interact with other Internet users. Collaborative systems are becoming more popular. Applications now being introduced could provide better remote education...
This thesis considers the two special sensor networks for future sensor network design: mobile sensor networks and hybrid network of sensors and robots. To investigate two types of networks, we abstract two most important aspects that are ingrained...
Autoimmune hepatitis (AIH) is an autoimmune liver disease characterized by immune-mediated necroinflammatory liver damage associated with CD4 + T cell infiltration in liver parenchyma. Despite advances in the understanding of AIH, its etiology...
Brain tumors account for ~2% of all cancers, with gliomas accounting for ~70% of all brain tumors. Evidence suggests that extent of resection provides both a quality of life and survival benefit to patients. Recent work has shown the utility of...
NAD (Coenzyme) -- Metabolism. Nicotinamide -- Mechanism of action. Genetic regulation. Nicotinamide-beta-riboside.
NAD+ is an essential co-enzyme for hydride transfer enzymes and a consumed substrate of multiple signaling enzymes including the sirtuins, a family of protein lysine deacetylases shown to regulate longevity in a wide array of organisms. We have...
A novel synthetic route to the synthesis of 9-propyl-10-azacyclododecan-12-olide (1), a natural allomone isolated from the Mexican bean beetle pupa, is presented. The salient features of this synthetic route are a regioselective Beckmann...
NIMA-related kinases (Neks) control several aspects of cell division downstream of master mitotic regulators such as Cdk1 and Plk1. Though depletion of Nek6, Nek7, or Nek9 results in cytokinesis failure, to date no molecular mechanism has been...
Acyl-coenzyme A: cholesterol acyltransferase (ACAT) plays important roles in cellular cholesterol homeostasis and in early stages of atherogenesis. ACAT has been investigated as a pharmaceutical target, yet its active site(s) remain largely...
The motivational and rewarding properties of our immediate environment affect how humans interact with our world in a number of ways. One important aspect in which reward representation shapes behavior is in the development, maintenance and...
Liver disease of different etiologies confers significant morbidity and mortality and hence it constitutes a major health concern worldwide. Stemming from a range of causes, such as viral, drug-induced, alcoholic, or autoimmune, the rate of...
Proteins are ubiquitous in cells and are essential to a wide range of biological processes. Since existing proteins occupy only a small portion of the space of possible amino acid composition, understanding their sequence-structure-function...

The opportunistic pathogen Pseudomonas aeruginosa secretes a protein that triggers the accelerated degradation of the cystic fibrosis transmembrane conductance regulator (CFTR) in airway epithelial cells. This protein, known as the CFTR inhibitory...
We have a limited understanding of how an opinion is originated, how an opinion and information supporting and explaining it gets conveyed, and how the communicated opinion is perceived and processed by others. One direction of current research...

Kynurenic acid (KYNA) is produced and released by astrocytes, and acts as an α7-nicotinic acetylcholine receptor antagonist (at lower, physiological concentrations) and an antagonist of the glycine site of the NMDA receptor (at higher,...
The identification of molecular alterations present in cancer is critical to better understand carcinogenesis as well as the clinical trajectories of patients with malignant tumors. Early detection and application of appropriate treatment...
Diagnostic imaging -- Mathematics. Expectation-maximization algorithms. Imaging systems in medicine -- Mathematics.
We have developed a general-purpose registration algorithm for medical images and volumes. The transformation between images is modeled as locally affine but globally smooth, and explicitly accounts for local and global variations in image...
As methicillin-resistant Staphylococcus aureus (MRSA) hospitalizations keep increasing, the understanding of the characteristics that make one isolate more successful over another is paramount. Strain variations among Staphylococcus aureus observed...
