Nanopatterning of biomolecules on functionalized surfaces offers an excellent route for ultrasensitive protein immobilization, for interaction measurements, and for the fabrication of devices such as protein nanoarrays. An improved understanding of the physics and chemistry underlying the device properties and the recognition process is necessary for performance optimization. This is especially...
A microcompressor is a precision mechanical device that flattens and immobilizes living cells and small organisms for optical microscopy, allowing enhanced visualization of sub-cellular structures and organelles. We have developed an easily fabricated device, which can be equipped with microfluidics, permitting the addition of media or chemicals during observation. This device can be used on bo...
Single-molecule magnets (SMMs) hold promise for unmatched information storage density as well applications in quantum computing and spintronics. To date, the most successful SMMs have been organometallic lanthanide complexes. However, their surface immobilization, one of requirements device fabrication commercial application, remains challenging due to sensitivity magnetic properties small chan...
We developed a new method for immobilization of the fix lower extremities by using a thermoplastic mask, a carbon fiber base plate, a customized headrest, and an adjustable angle holder. The lower extremities of 11 patients with lower extremity tumors were immobilized by this method. CT simulation was performed for each patient. For all 11 patients, the device fit was suitable and comfortable a...
Brain abscess as a complication of halo traction: role of CT in diagnosing penetration of the skull.
The occurrence of a brain abscess as a complication of halo traction and immobilization in the management of scoliosis is reported. Previous reports suggest that this complication is rare. Unique in this case is the development of an intracerebral abscess without skull perforation by the halo device and without evidence of contiguous spread of infection. Attention of clinical signs (headache) a...
Patients with connective tissue disorders are clinically challenging for radiation oncologists as these patients may be at increased risk for radiation-related skin toxicity. A clinical dilemma presents itself in a patient with lupus who presents with confluent skin lesions from mycosis fungoides requiring radiotherapy. In this report, we discuss an innovative technique used to develop an immob...
The paper proposes a multiparameter sensor platform capable of measuring the rate and thermal stress state which the user (in particular a firefighter) is subject to. For that, three wearable sensors (temperature, humidity and heart rate) send the information via Zigbee low energy wireless protocol, to a remote device (smartphone, wrist watch or PDA) monitoring the status of the worker. Additio...
An electrochemical aptasensor is a compact analytical device where the bioreceptor (aptamer) is coupled to a transducer surface to convert a biological interaction into a measurable signal (current) that can be easily processed, recorded and displayed. Since the discovery of the Systematic Evolution of Ligands by Enrichment (SELEX) methodology, the selection of aptamers and their application as...
We investigated the effects of bed rest (BR) immobilization, with and without computerized cognitive training with virtual spatial navigation task (CCT), on vascular endothelium on older subjects. The effects of 14-day BR immobilization in healthy older males (n=16) of ages 53-65 years on endothelial function were studied using EndoPAT(®), a noninvasive and user-independent method. From the gro...
