Immune mediators associated with human tuberculosis (TB) remain poorly defined. This study quantified levels of lung immune mediator gene expression at the time of diagnosis and during anti-TB treatment using cells obtained by induced sputum. Upon comparison to patients with other infectious lung diseases and volunteers, active pulmonary TB cases expressed(More)

In this work we use the method of consistent deformations of the master equation by Barnich and Henneaux in order to prove that an abelian topological coupling between a zero and a two form fields in D=3 has no nonabelian generalization. We conclude that a topologically massive model involving the Kalb-Ramond two-form field does not admit a nonabelian(More)
We analyze the one-dimensional Dirac oscillator in a thermal bath. We found that the heat capacity is two times greater than the heat capacity of the one-dimensional harmonic oscillator for higher temperatures. The name Dirac oscillator was first introduced by Moshinky and Szczepaniak [1] for a Dirac equation in which the momentum p is replaced by p →(More)
Starting from a recently proposed Abelian topological model in (2+1) dimensions , which involve the Kalb-Ramond two form field, we study a non-Abelian generalization of the model. An obstruction for generalization is detected. However we show that the goal is achieved if we introduce a vectorial auxiliary field. Consequently, a model is proposed, exhibiting(More)
Starting from a recently proposed abelian topological model in (2+1) dimensions , we use the method of the consistent deformations to prove that a topologi-cally massive model involving the Kalb-Ramond two form field does not admit a nonabelian generalization. The introduction of a connection-type one form field keeps the previous result. However we show(More)
By dimensional reduction of a massive supersymmetric B∧F theory, a manifestly N = 1 supersymmetric completion of a massive antisymmetric tensor gauge theory is constructed in (2+1) dimensions. In the N = 1−D = 3 super-space, a new topological term is used to give mass for the Kalb-Ramond field. We have introduced a massive gauge invariant model using the(More)
