background and objectives: phospholipase of mycobacterium tuberculosis plays an important role in pathogenesis through breaking up phospholipids and production of diacylglycerol. in this study, we examined the beijing strains of mycobacterium tuberculosis isolated from iranian patients for the genes encoding this enzyme. materials and methods: dna extraction was performed using ctab (cetyltrime...

background and objective: molecular epidemiological studies have shown that certain genotypes of mycobacterium tuberculosis (mtb) are over-represented in limited geographical regions, suggesting of evolution of certain genotypes with increasing virulence and pathogenicity. beijing strain of mtb was initially described by its potential to cause outbreaks worldwide and its association with drug r...

Assessing and quantifying atmospheric vulnerability is a key issue in urban environmental protection and management. This paper integrated the Analytical hierarchy process (AHP), fuzzy synthesis evaluation and Geographic Information System (GIS) spatial analysis into an Exposure-Sensitivity-Adaptive capacity (ESA) framework to quantitatively assess atmospheric environment vulnerability in the B...

background: beijing family of mycobacterium tuberculosis (m. tuberculosis) is widespread in asia and has been involved in outbreaks of multidrug-resistant tuberculosis in various parts of the world.  the aim of the current study was to evaluate the frequency of beijing family of m. tuberculosis in patients with tuberculosis in mashhad, iran. materials and methods: totally, 72 specimens of m. tu...

In order to increase the luminosity of Beijing ElectronPositron Collider (BEPC), the single interaction point (SIP) schemes were adopted. Then the electron and positron beams were separated at the north IP and collided at the south IP. Some experiments were done during these years. The results are given in the paper.
