background urinary tract infection (uti) is common in children. uti with or without vesico-ureteral reflux (vur) may result in renal scarring. severe renal scarring impairs renal function and may result in hypertension, renal insufficiency, and end stage renal disease requiring dialyses or transplantation. beta 2 micro-globulin (ß2mg) is a low molecular weight protein freely filtered by the glo...

background : hepatitis includes a wide range of clinical and pathological conditions. the beta-2 microglobulin (ãÿ2m), as part of thehla complex, is responsible for transmission of viral antigens on the surface of liver cells. the purpose of this study is to determine the concentration of salivary ãÿ2m as a marker of viral proliferation in subjects who are hbsag + , hbv dna pcr + compared with ...

For some $$\beta \ge 1/2$$ , a $$\varDelta _{\beta }$$ -metric graph $$G=(V,E,w)$$ is complete edge-weighted such that $$w(v,v)=0$$ $$w(u,v)=w(v,u)$$ and $$w(u,v) \le \beta \cdot (w(u,x)+w(x,v))$$ for all vertices $$u,v,x\in V$$ . A $$H=(V', E')$$ called spanning subgraph of $$G=(V, E)$$ if $$V'=V$$ $$E'\subseteq E$$ Given positive integer p, let H be G satisfying the three conditions: (i) ther...

background brucellosis is an important cosmopolitan infection disease caused by organisms belonging to the genus brucella. the cgt gene (cyclic β-1, 2 glucan transporter gene) is a virulent factor in brucella genus. the present study was conducted with the aim of cloning and expression of brucella cgt gene. materials and methods brucella melitensis cgt gene was amplified from extracted chromoso...
