Host-Guest Encapsulation of RIBO with TSC4X: Synthesis, Characterization, and Its Application by Physicochemical and Computational Investigations.

In our present work, we synthesized a new encapsulated complex denoted as RIBO-TSC4X, which was derived from an important vitamin riboflavin (RIBO) and -sulfonatothiacalix[4]arene(TSC4X). The synthesized complex RIBO-TSC4X was then characterized by utilizing several spectroscopic techniques such as H-NMR, FT-IR, PXRD, SEM, and TGA. Job's plot has been employed to show the encapsulation of RIBO (guest) with TSC4X (host) having a 1:1 molar ratio.

Excision of rare carotid body tumour without preembolisation: Case report and literature review.

Introduction: Carotid body tumors also known as parganglioma or chemodactomas are one of the rare tumors of head and neck which present as slow growing masses in the neck region. We present a case of 40 years female with painless slow growing mass over left side of her neck for 6 months. Diagnosis was made on basis of clinical history, examination and radiological findings.
