intracranial aspergilloma is extremely rare. the diagnosis and treatment of invasive cns aspergillosis is very difficult. early diagnosis is important for a successful treatment. here, we report a case of intracranial aspergilloma in an 11-year-old boy in 2013. good outcome was achieved by treatment with a combination of neurosurgical resection and antifungal administration, which we suggest is...

noncoding ribonucleic acids micro-rna is involved in the regulation of gene expression have major roles in the post-transcriptional level. a micro-rna alone several causes down regulation of mrna transcript of the target. thus, small changes in the expression of a micro rna may lead to significant changes in gene expression are different. micro- rna as key regulators of immune cell lineage diff...

this article examines the livelihood strategies of land scarce peasants in ethiopian. land scarce peasants have a limited livelihood security on a sustainable manner and bypassed by major development programmes. the study was centred on two sets of rationales. first, for those peasants who do not have sufficient farmland, agriculture provides only a limited portion of households’ livelihood sec...

background: proper placement of central venous catheter (cvc) tip could reduce early and late catheter-related complications.although the live fluoroscopy is standard of care for placement of the catheter, it is not available in many centers. therefore, the present study evaluated the sensitivity and specificity of bedside chest x-ray (cxr) for proper positioning of the catheter tip. materials ...

conclusions the us-guided method for cvc placement was superior to the traditional landmark method in terms of access time, number of attempts, success rate, and fewer complications. objectives this study aimed to compare the traditional landmark method vs. us-guided method of cvc placement in terms of complications and success rate. patients and methods in this randomized controlled trial, pat...

conclusions despite close concordance between ultrasonography and chest radiography, ceus is not a suitable alternative for standard chest radiography in detecting cvc location; however, considering its high sensitivity and acceptable specificity in our study, its usefulness as a triage method for detecting cvc location on a real-time basis in the operating room cannot be ignored. results chest...
