An ethical clearance was obtained from the institutional ethical committee of the hospital. Patients’ informed written consent was obtained. Two experienced spinal surgeons performed all operation procedures on these patients, and the operative materials, including puncture needles, bone cement, and ...
Based on our findings, it is plausible that HPV existing in the biofilm and extracellular space represents a reservoir of latent oncovirus that can functionally escape immune surveillance and clearance. Reactivation of these virions with subsequent infection of the basal epithelial layer may result in...
serving as a critical cornerstone of tumour-targeted drug delivery [82,83]. EPR-mediated tumour accumulation has traditionally been thought to be caused by long-circulating NPs with hydrodynamic diameters wider than the renal clearance threshold, which can extravasate from leaky...
and thereby a (patient) - specific connection is insured specific connection of the implant is ensured during the planning and design of the implant, and may imply that a clearance of 0.1 to 0.5 mm is provided in specific areas between the implant CAD model and the prepared bone CAD model....
The purpose of preoperative evaluation is not to give medical clearance but rather to perform an evaluation of the patient's current medical status; make recommendations concerning the evaluation, management, and risk of cardiac problems over the entire perioperative period; and provide a clinical ...
1, the slot 76 is sufficiently wide to receive the distal end 53 of the jet nozzle assembly 46 with minimal clearance for lateral translation in a chordal path. The guide member further includes an aspiration groove 77 formed annularly within the opening 63 and disposed in diametrical ...
The tubular guide sections 364 and 366 (FIGS. 40, 41 and 42) extend into the arcuate clearance openings 340 and 342 (FIG. 35) in the cam base plate 334. A pair of lock screws 380 and 382 (FIG. 3) extend through adjustment slots 384 and 386 (FIGS. 3 and 40) formed in the ...
The reason for the slotted wall 2114′ is that for some individuals and/or some disc locations, additional clearance may serve to facilitate placing the springs over as wide an area as possible. However, as the slots reduce the support and attachment to the cortical bone of the vertebral body...
32C, needle advancement member (960) is initially positioned such that there is at least some clearance between cannula sled (910) and needle advancement member (960). Although not shown, it should be understood that in some examples, such a clearance may be maintained with a removable member...
In operation, the perimeter of the device, and any openings therein, form the template or mold cavity around and into which tissue flows, thereby creating a tissue structure that reflects the geometry of the mold. That is, as the devices are configured such that portions of the stomach wall...
