Spatially Encoded Transfer of 1H Polarization to 13C for Uniform 1 JCH-Response in HSQC Open
Two dimensional (2D) NMR display better resolution than one-dimensional (1D) 1H NMR. However, 2D NMR does not display a straightforward quantitative aspect due to J-dependent polarization/coherence transfer. 1D 1H NMR is versatile for quan…

Surgical alternative to tracheoesophageal prosthesis for voice preservation in selected hypopharyngeal carcinoma Open
Background: Pearson’s near-total laryngectomy (NTL) is a voice- preserving alternative to total laryngectomy in patients with advanced but localized laryngeal and hypopharyngeal cancers, wherein lung- powered speech is achieved by creation…

Estimation of bone mineral density and its correlations with homocysteine, and various other biochemical bone markers in postmenopausal women Open
Introduction- Omocysteine (HCY) prevents collagen cross-linking and activates osteoclast function within the bones. Bone mineral density (BMD) may be affected by Hyperhomocysteinemia via Cathepsin K. Aim- To find the correlation of BMD wit…
