Hypermutation in immunoglobulin genes produces a high frequency of substitutions of all four bases, which are likely generated by low-fidelity DNA polymerases. Indeed, humans deficient for DNA polymerase (pol) eta have decreased substitutions of A.T base pairs in variable and switch regions. To study the role of pol eta in a genetically tractable system, we created mice lacking pol eta. B cells...
PURPOSE To determine the importance of Pseudomonas aeruginosa exotoxin A (ETA) as a virulence factor in corneal disease. METHODS Isogenic mutants deficient in ETA were constructed in P. aeruginosa strains PAO1 and ATCC 19660 by allelic exchange and then evaluated for virulence in a mouse model of bacterial keratitis. The effect of ETA on adherence to scarified corneal epithelium was assessed ...
Gaur egun hizkuntzak irakatsi zein ikasteko hainbat tresna informatiko dauzkagu merkatuan. Euskararen kasuan ere hainbat bide jorratu dira dagoeneko. Izan ere, hizkuntzen irakaskuntzaren arloan aukera asko ematen ditu informatikak. Batzuk hizkuntza bat ikasteko metodo edota osagarri gisa aurkezten dira. Beste batzuk, nahiz eta hizkuntza bat irakasteko izenburupean ez saldu, erabilgarri gerta da...
Using psi(2S)-->pi;{+}pi;{-}J/psi, J/psi-->gammaeta;{'} events acquired with the CLEO-c detector at the CESR e;{+}e;{-} collider, we make the first observations of the decays eta;{'}-->pi;{+}pi;{-}pi;{0} and eta;{'}-->pi;{+}pi;{-}e;{+}e;{-}, measuring absolute branching fractions (37_{-9};{+11}+/-4)x10;{-4} and (25_{-9};{+12}+/-5)x10;{-4}, respectively. For eta;{'}-->pi;{+}pi;{-}pi;{0}, this re...
RNA polymerase activity is regulated by nascent RNA sequences, DNA template sequences, and conserved transcription factors. Transcription factors promoting initiation and elongation have been characterized in each domain, but transcription termination factors have been identified only in bacteria and eukarya. Here we describe euryarchaeal termination activity (Eta), the first archaeal terminati...
We analyze the problem of fully implementing a social choice set in ex post equilibrium. We identify an ex post monotonicity condition that is necessary and—in economic environments—sufficient for full implementation in ex post equilibrium. We also identify an ex post monotonicity no veto condition that is sufficient. Ex post monotonicity is satisfied in all single crossing environments with st...
In this paper, we prove Hyers-Ulam-Rassias stability of $C^*$-ternary algebra homomorphism for the following generalized Cauchy-Jensen equation $$eta mu fleft(frac{x+y}{eta}+zright) = f(mu x) + f(mu y) +eta f(mu z)$$ for all $mu in mathbb{S}:= { lambda in mathbb{C} : |lambda | =1}$ and for any fixed positive integer $eta geq 2$ on $C^*$-ternary algebras by using fixed poind alternat...
The main aim of the present study was to investigate the direct inotropic effects of stimulation of the endothelin (ET) receptor ETA under in vivo conditions. It is well known that ETA receptor stimulation causes pronounced vasoconstriction. The ET-1-induced coronary vasoconstriction may lead to myocardial ischaemia and, consequently, to cardiodepressor effects that may mask the direct positive...
A variety of substituted titanocene and ansa-titanocene complexes have been synthesized and characterized using traditional methods. The cytotoxic activity of the different titanocene complexes was tested against tumour cell lines human adenocarcinoma HeLa, human myelogenous leukemia K562, human malignant melanoma Fem-x and normal immunocompetent cells, peripheral blood mononuclear cells PBMC. ...
