Introduction Recent studies have shown that sequential irradiation/annealing processes improves the wear performance and oxidation resistance of crosslinked polyethylene, while maintaining mechanical properties [1,2]. Although these early results showed great promise for mechanically enhanced XLPE, we still know little about the variables that can lead to high-wear, particularly surface roughne...

background: recent studies have shown a positive correlation between helicobacter pylori infection and migraine headache. the aim of this study was to evaluate the role of h. pylori infection in migraine headache with (ma) and without aura (mo). methods: this is a case-control study containing information on 84 patients (including ma, mo) and 49 healthy individuals . the enzyme-linked immunosor...

traumatic head injury is the underlying cause of approximately 5% of all persons with epilepsy and is the major cause of epilepsies starting in young adulthood. penetrating head injury, particularly among soldiers, carries a risk of almost 50% of developing post-traumatic epilepsy (pte), mostly within 6 months to two years after the trauma. early seizures (within one week of the trauma) are dep...

background: pediculosis capitis is a common parasitic infection of children. in this study we assessed the prevalence of head pediculosis among the middle schoolchildren in the urban and rural areas of fars province, southern iran.methods: all middle schoolchildren ages 11-14, in all the urban and rural areas of the province were screened for head lice infestation by examining their hair and sc...

conclusions increased serum levels of interleukins 6 and 8 as a predictive marker might be associated with unfavorable clinical outcome in patients with severe tbi. results comparing the serum levels of interleukins in two groups with favorable and unfavorable clinical outcomes showed that the mean serum levels of interleukins 6 and 8 in group with favorable outcome was 85.2 ± 51.6 and 52.2 ± 3...

The main objective of this paper was to manipulate the Nano Fibrous Scaffold "NFS" surface roughness to achieve a new transdermal drug release profile. To assess the intrinsic mechanical properties of Nylon 6 or polycaprolactam, such as its proper resiliency, it was considered as the matrix. Cetirizine was used as a drug model and was loaded (1% w/v) to polymer solution (30%w/v) before spinning...
