The axonal kinematic response to different level of strain was examined in developing chick embryo spinal cords. Spinal cords were dissected from chick embryos at different days of development (E12, E14, E16, and E18), and the myelination of chick embryo spinal cord was characterized by immunohistochemical labeling of myelin basic protein (MBP), which is synthesized in the myelination process. ...

A case of monochorionic-monoamniotic (MCMA) twin pregnancy with growth discordance because of difference of cord diameter in forked umbilical cord is reported.MCMA twins were diagnosed at 12 weeks of gestation and twin growth discordance was considered during the follow-up twice-weekly visits to the ultrasound and prenatal care units. The pregnancy was terminated at 34 weeks. Two live female ba...

Mycelial development of Phanerochaete velutina extending from wood inocula in 57 x 57 cm trays of non-sterile soil was characterized after adding: (1) collembola; (2) new wood resources; (3) both new wood resources and collembola; and (4) no new resources and no collembola. After 99 d, all systems had produced distinct mycelial cords, much of the diffuse mycelium and thinner cords that were pro...

case presentation herein, we reported a case of a 22-year-old woman diagnosed with erms, t1n0m0 stage, localized at the right vocal cord. tumor was successfully treated with a radical excision and selective neck dissection and followed-up for 5 years with no evidence of local recurrence. introduction although embryonal rhabdomyosarcomas (erms) represent the most common (50% - 60%) clinical form...

Although it is known that aging plays an important role in the incidence and progression of cervical spondylotic myelopathy (CSM), the underlying mechanism is unclear. Studies that used fresh bovine cervical spinal cord report the gray matter of the cervical spinal cord as being more rigid and fragile than the white matter. However, there are no reports regarding the association between aging a...

This paper investigates experimentally the structural performance of substandard reinforced concrete (RC) short columns confined with steel-reinforced grout (SRG) jackets under monotonically increasing uniaxial compression. The study comprised 24 square cross section RC having alternative arrangements shear reinforcement (ratio stirrup spacing to longitudinal bar diameter ranging from 4.2 12.5)...

Platelet-derived growth factors (PDGFs) are paracrine factors with roles in mesenchymal-epithelial interactions during normal and pathologic processes. Previously, PDGF and its receptor (PDGFR) have been shown to be present in perinatal, peripubertal, and adult rat testes. The role of PDGF in embryonic testicular cord formation is not known. The hypothesis tested is that PDGFs and PDGFRs are ex...

OBJECTIVE To determine the efficacy in the intermediate term of artificial cords inserted in children with congenital mitral regurgitation. METHODS We reconstructed the tendinous cords using expanded polytetrafluoroethylene (ePTFE) sutures in 11 children with severe mitral regurgitation. In these patients, the aortic (anterior) leaflet of the mitral valve had been markedly prolapsed, the tend...
