Abstract
Silane-treated natural cellulosic Kigelia africana fruit fibre (KAF) was experimentally established to have strong strength after removing hydrophilic materials. Silane treatment makes it compatible with hydrophobic biopolymeric materials than existing non-grafted KA fibre. In this work, the polysaccharide was extracted from the KAF and found to have all the essential compounds. KA fruit-based cellulosic fibre was extracted and treated with different concentrations of silane solution. Silane-treated (13%) KAF has a cellulose content of about 76.86%. The peak found at 1734 cm-1 shows the hemicellulose in untreated fibres, and its intensity decreased after silane treatment, as confirmed by FTIR. X-ray diffraction investigation indicated that silane-treated (5%) KAF has a crystallinity index of 70.22%. After treatment, the tensile strength of 5% silane-treated KAF shows a tensile strength of 490.77 MPa, giving more viability to biofibre reinforcement.

Abstract
A novel cellulosic fibre was extracted from the peduncle portion of the fish tail palm tree and the extracted fish tail palm fibre was treated with different concentrations (1%, 5%, and 9%) of silane solution. The characteristic analysis on chemical, functional, mechanical and surface property of the extracted fish tail palm fibres were investigated through chemical composition analysis, Fourier Transform InfraRed spectroscopy (FT-IR), single fibre tensile test, and Scanning Electron Microscopy (SEM). Chemical analysis results indicate that silane treatment improved the cellulose content of the fish tail palm fibre. The highest cellulose content of 72.51% was observed in the 9% silane treated fish tail palm fibre. Also, it improved crystallinity index value of 62.5% for 5% silane treated fibre, which is confirmed through the X-ray diffraction analysis. FT-IR result indicates the removal of hemicellulose at characteristic wavelength of 1745 cm-1 for 5% silane treated fish tail palm fibre. Tensile property of the silane treated fish tail palm fibre (1, 5, and 9%) shows an increased tensile strength of 7.3%, 12%, and 6.6% as compared to raw fish tail palm fibre. Moreover, this type of novel natural fibres can reduce the cost while offering competent performance during the polymer-based product development.

Abstract
AbstractSacrum is a large triangular bone, forming postero-superior wall of the pelvic cavity. During the routine study of bones in the department of Anatomy, an unusual variation in the sacrum was noted. The bone showed high sacral hiatus i.e., at the level of 3rd sacral vertebrae and non-fusion of lamina of 1st sacral vertebrae This type of anomaly is very rare, which prompted us to report the case. The knowledge about this rare variation is important for orthopaedicians and anesthetists since the high sacral hiatus may lead to clinical procedural failures. It is also important for accurate diagnosis of patients with low back pain. Non-fusion of lamina of 1st sacral vertebrae may be associated with spina bifida occulta and may lead to painful condition of back.

Abstract
Renal angiomyolipoma is recognised as a benign hamartomatous lesion with no obvious malignant potential. However, the tumour may show extrarenal/perinephric extension at times. Rarely, the lesion may extend into the renal vein and inferior vena cava (IVC) indicating aggressive behaviour. We present a case of an angiomyolipoma of the kidney with sonographic, CT and MRI evidence of extension into the renal vein and IVC.
