Peripheral nerve research is highly dynamic and a current major focus is the development of cell based supportive therapies as well as bioengineered nerve conduits to overcome the challenges in reconstructing long peripheral nerve defects. Whenever primary nerve repair cannot be performed without regeneration impairing tension at the suture sites, autologous nerve grafting or nerve tubulization...

The optical light curve of the Be/neutron star binary AX J0049.4−7323 has been investigated using data from the MACHO and OGLE-II projects. This X-ray source, whose neutron star has a very slow rotation rate (P pulse = 755.5 sec), shows optical outbursts every ∼394 days. The regularity of these outbursts suggests that their recurrence time is the orbital period of the system. During the outburs...

OBJECTIVES/HYPOTHESIS Hematomas may develop in the postoperative setting after free tissue transfer. When hematomas occur, they can exert pressure on surrounding tissues. Their effect on the vascular pedicle of a free flap is unknown. We describe our incidence of hematoma in free flaps and outcomes when the flap is compromised. STUDY DESIGN Retrospective chart review of 1,883 free flaps perfo...

BACKGROUND AND PURPOSE A precise analysis of the immediate postoperative anatomic results in a large series of unruptured intracranial aneurysms treated by endovascular approach has not previously been presented. This study aimed to assess the efficacy of endovascular treatment of unruptured intracranial aneurysms in light of immediate postoperative anatomic results in a prospective, multicente...

Aberrant glycosylation during carcinogenesis results in altered glycan expression on oral cancer cells. The objective of this study was to detect this atypical glycosylation via imaging of fluorophore-conjugated lectins. Paired normal and tumor tissue from seven patients with oral squamous cell carcinoma were investigated for sialic acid expression via the legume protein wheat germ agglutinin (...

Background Sternocostoclavicular hyperostosis (SCCH) is an inflammatory bone disorder within the spectrum of chronic non-bacterial osteomyelitis. SCCH can be a manifestation SAPHO syndrome, standing acronym for synovitis, acne, pustulosis, and osteitis, but also appears as isolated clinical entity without joint skin involvement 1,2 . Consensus on nomenclature, diagnostic classification, therapy...

This paper reports on a comparison of gold and gold–nickel alloys as contact materials for microelectromechanical systems (MEMS) switches. Pure gold is commonly used as the contact material in low-force metal-contact MEMS switches. The top two failure mechanisms of these switches are wear and stiction, which may be related to the material softness and the relatively high surface adhesion, respe...

By ab initio LMTO calculations in atomic-sphere approximation we have studied the interlayer exchange coupling between Fe films separated by Au spacers in infinite Fe/Au multilayers with (001) interface orientation. We also performed detailed calculations of the magnetization and charge profiles across the system. We find an enhancement of the Fe moments at the interface, which amount to ≈ 2.8 ...
