The PND-1186 in vivo effect of percentage kenaf loading and particle size of kenaf (core) on the flexural properties of the composite was investigated. From the results, the incorporation of kenaf, regardless of particle size had resulted in the reduction of flexural strength of the composite. However, flexural modulus of the composites increased as the percentage of kenaf loading was increased due to the increasing of the stiffness contributed by kenaf fiber. Composites produced from internal mixer had displayed

higher flexural properties as compared to those prepared from high speed mixer and twin screw extruder. It was believed that this phenomenon was attributed to the effectiveness of internal mixer with a better compounding mechanism which improved the wetting and distribution on kenaf within the polypropylene matrix.

“Study Design. Review the presentation and diagnosis of an intradural extramedullary hemangiopericytoma of the thoracic spine.

Objective. To present a rare case of intradural, subpial hemangiopericytoma in the thoracic spine, with a brief overview of the literature.


Napabucasin cell line of Background Data. Spinal intradural extramedullary hemangiopericytoma is rare entity that radiographically mimics nerve-sheath tumors. These lesions are typically diagnosed at surgery performed due to suspicion of


Methods. A 20-year-old man who presented with back pain, leg weakness, and sphincter incontinence. MR imaging demonstrated an intradural extramedullary lesion at the T9-T10 level that was CH5424802 inhibitor isointense on T1- and T2-weighted images and homogeneously enhancing after administration of gadolinium, with cystic components seen on T2-weighted images. The preoperative diagnosis was meningioma or schwannoma.

Results. At surgery, the lesion was bluish and completely subpial, with apparent nerve root invasion. Pathological examination revealed a neoplasm adjacent to a nerve root with possible focal infiltration. Abundant reticulin fibers and widened, branching vascular channels imparting a staghorn appearance were seen. Up to five mitotic figures were counted in one high-power field. On immunostaining, the neoplastic cells were diffusely immunoreactive for CD99 and immunonegative for EMA, CD34, and S-100 protein. The pathological diagnosis was consistent with anaplastic hemangiopericytoma, WHO grade III.

Conclusion. This is the ninth report of spinal intradural hemangiopericytoma. The location of the neoplasm supports the hypothesis that hemangiopericytoma may arise from the spinal pial capillaries.
