OBJECTIVES To determine whether a novel marine micro-organism with anticancer properties, H31, the metabolic product of Bacillus SW31, has anti-tumor effects on head and neck cancer, and potential for apoptotic-enhancing anti-cancer treatment of affected patients. METHODS The cell viability and apoptosis assays were performed. Changes in the signal pathway related to apoptosis were investigat...

Post-translational modifications on proteins are important in biological processes but may create neo-epitopes that induce autoimmune responses. In this study, we measured the serum IgG and IgM response to a set of non-modified or acetyl- and methyl-modified peptides corresponding to residues 1-19 of the histone 3 N-terminal tail in systemic lupus erythematosus (SLE) patients and healthy subjec...

We describe the space of isometric immersions from the Lorentz plane L into the anti-de Sitter 3-space H31, and solve several open problems of this context raised by M. Dajczer and K. Nomizu in 1981. We also obtain from the above result a description of the space of Lorentzian flat tori isometrically immersed in H31 in terms of pairs of closed curves with wave front singularities in the hyperbo...

This paper proposes that the decline in federal disability insurance (DI) screening stringency raises the incentive of being uninsured. To support it, we provide a theoretical model and empirical evidence. JEL classification: I13, I18, H31, H51, H55

The subject of this note began with Thompson [Thl,2]. In the course of constructing his simple group Th, he considered the Lie algebra Lover iC of type Es. He constructed a decomposition L H1 ..L ... ..L H31 using a family H. {H1, ... , H31 } of Cartan algebras that are pairwise perpendicular with respect to the Killing form (he called this a "Dempwolff decomposition" of L; the construction was...

Analyzing account-level data from an account aggregator, we find that households increase consumption when they receive expected tax refunds, as if face liquidity constraints. However, these same smooth making payments in other years, primarily by transferring funds among liquid accounts. Even carrying credit card debt payments, and even highly spend out of refunds. This behavior is inconsisten...
