A family of circuits of a graph G is said to be independent if no two of the circuits have a common vertex ; it is called edge-independent if no two of them have an edge in common . A set of vertices will be called a representing set for the circuits (for the sake of brevity we shall call it a representing set), if every circuit of G passes through at least(More)
A prospective, randomized, double-blind study was designed to compare Clostridium difficile immune whey (CDIW) with metronidazole for treatment of laboratory-confirmed, recurrent, mild to moderate episodes of Clostridium difficile-associated diarrhoea (CDAD). CDIW was manufactured by immunization of cows in their gestation period with inactivated C.(More)
OBJECTIVE To compare ex vivo immunological responses upon stimulation of lymphocytes with Mycobacterium tuberculosis-specific antigens in three groups: 1) subjects diagnosed with tuberculosis (TB) in the early 1940s and 1950s but who did not receive anti-tuberculosis chemotherapy (n = 5), 2) subjects treated with anti-tuberculosis agents prior to the(More)
Diagnosis of active tuberculosis by detection of urinary lipoarabinomannan (uLAM) from Mycobacterium tuberculosis is an attractive approach. Concentrating urine 100-fold allowed quantitation of uLAM at levels equal to picograms/ml of nonconcentrated urine. The approach of concentrating urine 100-fold improved the clinical sensitivity of the Clearview TB(More)
The performance of the interferon gamma release assays (IGRAs) and tuberculin skin test (TST) was reviewed retrospectively in patients with psoriasis, inflammatory musculoskeletal diseases, or miscellaneous inflammatory conditions. The study was carried out over a 22-month period using 109 records of patients with psoriasis (n = 21), musculoskeletal disease(More)
BACKGROUND In recent years T cell based interferon gamma release assays (IGRA) have been developed for immunodiagnosis of M. tuberculosis infection. At present these assays do not discriminate between disease and latency. Therefore, more promising antigens and diagnostic tools are continuously being searched for tuberculosis immunodiagnostics. The heparin(More)
New biomarkers are needed for discriminating active tuberculosis (TB) from latent TB infection (LTBI), especially in vulnerable groups representing the major diagnostic challenge. This pilot study was carried out to explore the diagnostic potential of selected genes, IFN-γ, IL-17, IL-4, and FoxP3, associated with TB immunity and immunopathology. IFN-γ,(More)
BACKGROUND Data exploring the potential use of effector molecules produced by cytotoxic T lymphocytes (CTLs) in the immunodiagnostics of tuberculosis (TB) are scarce. The present study focused a) to gain an insight into the discriminatory power of CTLs in patients with acute pulmonary or extra-pulmonary TB, or latent tuberculosis infection (LTBI); and b) to(More)
