Extranodal spread (ENS) in patients with head and neck squamous cell carcinoma (HNSCC) can greatly influence the prognostic outcomes. However, the relative risks of ENS in the primary (1st) and secondary (2nd) metastatic nodes (mets) are not well documented. We retrospectively analyzed the hazard ratios (HRs) of ENS in the 1st and 2nd mets from 516 HNSCC patients who had undergone primary tumor...
The purpose of our study was to examine 1st metatarsophalangeal (MTP) joint motion and flexibility and plantar loads in individuals with high, normal and low arch foot structures. Asymptomatic individuals (n=61), with high, normal and low arches participated in this study. Foot structure was quantified using malleolar valgus index (MVI) and arch height index (AHI). First MTP joint flexibility w...
The length of the four right antennal segments from nymphs and adults of Panstrongylus megistus Burmeister, Rhodnius neglectus Lent, Rhodnius prolixus Stal and Triatoma vitticeps Stal were measured. The length of the antennal segments of the adults of all four species, 4th and 5th instars of P. megistus, and 5th instar of R. neglectus and R. prolixus followed the same pattern: 2nd>3rd>4th>1st. ...
background: several factors influence on the outcome of ischemic stroke. the aim of this study was determination the relationship between stroke mortality and red blood cell parameters. methods: this cross-sectional study was conducted from 2011 july to june 2012. for all patients with ischemic stroke in middle cerebral artery (mca) territory, the cell blood count test was performed. w...
In the current study the influence of weight percentage of HIPS, weight percentage of CNT and hardener content on damping 1st and damping 2nd properties of epoxy/HIPS/CNT hybrid composite wase valuated. Mixture design methodology was employed to generate mathematical models for predicting damping 1st and damping 2nd behaviors of new mentioned hybrid nanocomposite as function of physical factors...
Dislocation of the first carpometacarpal (CMC) is a rare occurrence. Treatment of this dislocation varies from closed reduction and casting to ligament repair. Neglected dislocation or incomplete reduction of the 1st CMC cause chronic instability and painful arthritis, muscle imbalance and decreased grip force. In our study 6 patients is evaluated that were visited in less than 24 hours from ...
Due to rapid industrialization and urbanization, environmental pollution has become a major concern in developing countries; therefore, the main objective of the current study is to determine heavy metal contents of Pb, and Ni for 42 topsoil samples, collected from 14 green spaces along the 1st and 2nd ring roads in Hamedan City in 2016. For this purpose, after determining some chemical propert...
We, the organizers and participants, report our experiences from the 1st Verified Software Competition, held in August 2010 in Edinburgh at the VSTTE 2010 conference.
This paper focuses upon the security characteristics of cryptographic mobility (CM) solutions. CM solutions allow the roaming user to make use of their cryptographic credentials from any workstation or system that has network connectivity to the appropriate credential server(s), without the need to carry portable software or hardware tokens. While CM implementations have a greater potential for...
This paper contrasts the use of an ID PKI (Public Key Infrastructure) with the use of delegatable, direct authorization. It first addresses some commonly held beliefs about an ID PKI – that you need a good ID certificate to use digital signatures, that the ID certificate should come from a CA that has especially good private key security, that use of the ID certificate allows you to know with w...
