One obstacle to wider use of rapid liquid culture-based tuberculosis diagnostics such as the microscopic observation drug susceptibility (MODS) assay is concern about cross-contamination. We investigated the rate of laboratory cross-contamination in MODS, automated MBBacT, and Lowenstein-Jensen (LJ) cultures performed in parallel, through triangulation of microbiologic (reculturing stored sampl...

We consider the version of the Zee model where both Higgs doublets couple to leptons. Within this framework we study charged Higgs decays. We focus on a model with minimal number of parameters consistent with experimental neutrino data. Using constraints from neutrino physics we (i) discuss the reconstruction of the parameter space of the model using the leptonic decay patterns of both of the t...

Using two different liquid media and one conventional solid medium, a total of 57 mycobacterial isolates (Mycobacterium tuberculosis, n = 55; nontuberculous mycobacteria, n = 2) were recovered from 377 clinical specimens. The rates of recovery of M. tuberculosis were 96. 4% with the BACTEC MGIT 960 liquid medium, 92.7% with BACTEC 12B liquid medium, and 81.8% with the Löwenstein-Jensen (LJ) med...

Buschke-Löwenstein tumor is a rare manifestation of a sexually transmitted human papilloma virus infection that affects the anogenital area. Wide local excision of the lesion is the mainstay of treatment. Malignancy though must be excluded.

Mycobacterial diseases continue to cause high morbidity and mortality. Isolation, identification and sensitivity testing form the backbone of laboratory investigations. M. tuberculosis isolation needs 6-8 weeks on conventional egg containing media. For rapid isolation various methods have been evaluated. We evaluated biphasic system (Middlebrook 7H11 agar slant+Middlebrook 9H broth) in comparis...

The average conformation of a flexible chain molecule in solution is coupled to the local solvent structure. In a dense solvent, local chain structure often mirrors the pure solvent structure, whereas, in a dilute solvent, the chain can strongly perturb the solvent structure which, in turn, can lead to either chain expansion or compression. Here we use Monte Carlo (MC) simulation to study such ...

Mycobacterium tuberculosis is a pathogenic organism, which causes high morbidity and mortality in human being. The disease tuberculosis is commonly seen in immunocompromised patients. M. tuberculosis takes time to grow on culture medium (Lowenstein-Jensen medium) for drug susceptibility testing to avoid delay, now a day molecular techniques are introduced in many developing countries including ...

Condyloma acuminatum caused by Human Papillomavirus is the most commonly occurring sexually transmitted infection in the anogenital region. Buschke-Löwenstein tumor (BLT) known also as giant condyloma acuminatum is a rare disease. The disease, for which the most important treatment method is the surgical excision, differs from normal condyloma acuminatum cases with its high degree of malignancy...
