A case study of a 20‑year‑old boy, product of non‑consanguineous marriage, presented with insidious onset, progressive, sensori‑motor quadriparesis with bowel and bladder incontinence over 3 months. Topics hyperintense intramedullary lesion with multiple intradural flow voids and homogenous contrast enhancement suggestive of a cervical hemangioblastoma; and treatment for loss of function or malignant transformation of the affected organ.

A new efficient catalytic method for aza/thia-Michael addition reactions of amines/thiols with higher product yields has been developed. Combining single-walled carbon nanotubes (SWCNT) with triethylammonium hydrogen phosphate (TEAP) ionic liquid (IL) can work as a catalyst. We utilized Raman spectroscopy to gain insight into the interactions between IL and SWCNT. The interactions between SWCNT with TEAP were confirmed by the increasing intensity ratios and spectral shift in wavelength of the Raman D and G bands of SWCNT. Further, the morphology of the resulting composite materials of TEAP and SWCNT was determined by using scanning electron microscopy (SEM). Higher product yield in reduced reaction time is the key advantage of using bucky gel as a catalyst for Michael reaction. [ABSTRACT FROM AUTHOR]
