The arterial supply to the flexor tendons of the fingers was studied by means of angiography, by the injection of coloured latex, and by microdissection. It was established that there were no anastomoses between the intra-osseous circulation and that of the synovial sheath. Two separate sources of blood supply to the sheath were found: the digitopalmar arches and the specific arteries of the sh...

We present a robust method to prepare thin oriented nematic liquid crystalline elastomer-polymer (LCE-polymer) core-sheath fibers. An electrospinning setup is utilized to spin a single solution of photo-crosslinkable low molecular weight reactive mesogens and a support polymer to form the coaxial LCE-polymer fibers, where the support polymer forms the sheath via in situ phase separation as the ...

background and objective: approximately 45% of benign peripheral nerve sheath tumors (pnst) occur in head and neck regions. malignant peripheral nerve sheath tumors (mpnst) are less common and only 8-15% of these tumors occur in head and neck region. in this study, we aimed at evaluating the demographic characteristics, pathologic findings, locations, main clinical presentations and family hist...

Various process parameters for the production of polygalacturonase by Streptomyces lydicus under solid-state fermentation were optimized. The optimum particle size of wheat bran for polygalacturonase production was in the range of 500-1000 μm. Initial moisture content of 70% was found to be the optimum for enzyme production. The most suitable inoculum size was 1.25 × 10(5) CFU/mL and the optimu...

The morphology and function of the splenic sheath have been thoroughly discussed. Schweigger-Seidel (1863) first pointed out that a high permeability was seen on the wall of the sheathed vessel. Later some research workers who used color suspension materials for investigating the sheathed vessel have mentioned that the material leaked from the wall of the vessel into the sheath. Ohta (1957) des...

Parylene C arrayed neural probes possessing 3D sheath structures that can be decorated with neurotrophic factors for attracting and promoting neural tissue ingrowth are presented for long-term intracortical neural recording. 3D sheath structures were constructed through thermoforming of surface micromachined Parylene microchannels around a solid microwire mold. Multiple Pt electrodes were patte...

background :there is not any data available about the effect of high bar pressure condition on intracranial pressure. in this study, the effect of diving on the optic nerve and sheath diameters as non-invasive markers of intracranial pressure has been investigated.   methods : twenty professional male divers from twenty one volunteers were chosen for this cross-sectional study. only one person ...

Intercropping systems compared to monoculture systems can more efficiently use the existing resources which ultimately will lead to increased plant performance. Therefore, to evaluate the benefits of intercropping maize and beans and assess its impact on yield and yield’s component, an experiment was conducted in factorial design with randomized complete block design in three replication, in 20...

Aging of the nervous system leads to impairments in cognition and motor skills, and is a major risk factor for several neurological disorders. Recently, numerous nerve function deficits that appear with aging have been found to be a consequence of myelin abnormalities; however, the genetic mechanism of the age‑related alterations in the myelin sheath has not yet been fully elucidated. In the pr...

Most works on plasma-wall interaction predict that with strong electron emission, a nonmonotonic "space-charge-limited" (SCL) sheath forms where the plasma potential is positive relative to the wall. We show that a fundamentally different sheath structure is possible where the potential monotonically increases toward a positively charged wall that is shielded by a single layer of negative charg...
