background & importance: acute epidural hematoma is a very rare complication of ventriculoperitoneal shunt insertion. the insertion of a ventriculoperitoneal shunt can cause sudden decompression of the brain, subsequent to which epidural hematoma occurs due to csf drainage. to our knowledge, there are only a few cases of acute epidural hematoma in the literature which required acute evacuation....

background : there are various variables such as the duration and the client consistency' in using a special contraceptive method as well as some individual determinants. which play important roles in optimal using of different contraceptive methods. iud cu- 380a is a safe and an effective method used by 12.5% urban women in east azarbaijan. correlation between continuation rate of using iud cu...

angiotensin i-converting enzyme (ace) gene polymorphism; genotype dd or d allele may be involved with an increased susceptibility to type 2 diabetes and diabetic nephropathy (dn). we examined the frequency of ace gene polymorphism in 170 patients (85 type 2 diabetes with nephropathy and 85 without it) in tehran, iran. dna was extracted from the white blood cells and the i/d polymorphism of the ...

Background: Iatrogenic urethral injury is a well-known risk of urinary catheter insertion. Associated morbidities include stricture formation, catheter associated infection, risk for instrumentation, and extended length of stay. Yet, insufficient attention is paid to its prevention. Objective: This study aimed to assess the effectiveness of a computerized...

In ad hoc wireless networks, nodes are typically powered by batteries. Therefore saving energy has become a very important objective, and different algorithms have been proposed to achieve power efficiency during the routing process. Directional antenna has been used to further decrease transmission energy as well as to reduce interference. In this paper, we discuss five algorithms for routing ...

Random transposon insertion libraries have proven invaluable in studying bacterial genomes. Libraries that approach saturation must be large, with multiple insertions per gene, making comprehensive genome-wide scanning difficult. To facilitate genome-scale study of the opportunistic human pathogen Pseudomonas aeruginosa strain PA14, we constructed a nonredundant library of PA14 transposon mutan...
