Polyhydroxybutyrate-co-hydroxyvalerate copolymer modified graphite oxide based 3D scaffold for tissue engineering application.

In this study, we have fabricated the PHBV functionalized graphite oxide using freeze drying technique, followed by 'in situ' pay loading of FeO nanoparticles onto the hydrophobic plate of the composite basal plane; thereby, mechanically and thermally stable, bio-imaging FeO/GO-g-PHBV composites have been developed. The synthesis of FeO/GO-g-PHBV composite was confirmed by field emission SEM and TEM analyses, X-ray diffraction and Fourier transform infrared spectroscopy. The wrapping of PHBV copolymer into the graphene layers was investigated by atomic force microscopy and Raman spectral analyses which provided the shifting of the 2D band with low signal intensity in the range of 2600-3000 cm.

Mature teratoma of the mesentery.

Teratoma of the mesentery is an extremely rare tumour of the germ cells and imposes diagnostic dilemma in clinical practice and is reported because of its very uncommon occurrence. With the advent of modern imaging modalities like ultrasonography, computerised tomography (CT) and magnetic resonance imaging (MRI), it is now confidently diagnosed and rarely requires diagnostic laparotomy. CT shows characteristic appearance (Rokitansky sign).
