It is unknown whether MIRU-VNTR (Mycobacterial Interspersed Repetitive Unit-Variable Number of Tandem Repeat) is associated with drug resistance of Mycobacterium tuberculosis. The purpose of this study was to explore the ability of 24 MIRU loci to predict the drug resistance of Isoniazid (INH), Rifampicin (RFP), Streptomycin (SM), Ethambutol (EMB) and Pyrazinamide (PZA). We collected the drug r...

We work in the smooth category. If there are knotted embeddings S → R, which often happens for 2m < 3n+4, then no explicit complete description of the embeddings of n-manifolds into R up to isotopy was known, except for the disjoint unions of spheres. Let N be a closed connected orientable 3-manifold. Our main result is the following description of the set Emb(N) of embeddings N → R6 up to isot...

BACKGROUND Due to the increasing prevalence of Mycobacterium tuberculosis strains resistant to one or more antibiotics, there is a need for new quantitative culture methods both for drug susceptibility testing and for validation of mutations putatively associated with drug resistance. We previously developed a (myco) bacterial culture method, in which multiple growing microcolonies are monitore...

Expression of the mouse cardiac actin gene depends on a distal enhancer (-7 kbp) which has been shown, in transgenic mice, to direct expression to embryonic skeletal muscle. The presence of this distal sequence is also associated with reproducible expression of cardiac actin transgenes. In differentiated skeletal muscle cells, activity of the enhancer is driven by an E box, binding MyoD family ...

BACKGROUND The increasing problem of multi-drug-resistant (MDR) tuberculosis (TB) [ie resistant to at least isoniazid (INH) and rifampicin (RIF)] is becoming a global problem. Successful treatment outcome for MDR-TB depends on reliable and accurate drug susceptibility testing of first-line and second-line anti-TB drugs. METHOD Consecutive M. tuberculosis isolates identified as MDR-TB during A...

BACKGROUND AND OBJECTIVES The aim of this randomized, double-blinded, prospective study was to determine the effectiveness and side effects of intravenous or epidural use of morphine, bupivacaine or ropivacaine on post-thoracotomy pain management. METHODS Sixty patients undergoing elective thoracotomy procedure were randomly allocated into 4 groups by the sealed envelope technique. Group IVM,...

Human and animal studies have revealed a strong association between periconceptional environmental factors, such as poor maternal diet, and an increased propensity for cardiovascular and metabolic disease in adult offspring. Previously, we reported cardiovascular and physiological effects of maternal low protein diet (LPD) fed during discrete periods of periconceptional development on 6-month-o...

Background The diagnosis of myocarditis is still a challenge. The true incidence of the disease is unknown due to great variation in clinical manifestations. Objective The aim of this study was to identify the demographic features and in-hospital prevalence of myocarditis in patients undergoing transarterial endomyocardial biopsy (EMB) for unexplained cardiomyopathy. Patients and methods Th...

conclusions we concluded from the results that the frequency of emb-resistant m. tuberculosis cases in iran is lower than that of many other regions. the pcr-sscp technique can separate resistant isolates from sensitive isolates. the sequencing results of this study showed mutation in codons 309 and 299 of the embb gene. in none of the resistant isolates, mutation was observed in codon 306. fur...
