Thermal and solutal transport by Cattaneo-Christov model for the magnetohydrodynamic Williamson fluid with joule heating and heat source/sink.

This article scrutinizes the 2-dimensional and boundary layer flow of magnetohydrodynamic Williamson fluid flowing on a stretchable surface with variable viscosity. The thermal and solutal rates are examined through the Cattaneo-Christov model with Joule heating, heat source/sink, and chemical reaction. The authors are motivated to conduct this study because of its practical and scientific significance in various processes, including polymer processing, textile industries, food industries, solar energy, biomedical science, wind turbine blades, oil spill clean-up, metal rolling, and forging.

Paradoxical Hyperreflexia in a Patient With Classic Guillain-Barré Syndrome.

Background: Guillain-Barré syndrome (GBS) is a rare entity with characteristic features, including progressive ascending paralysis. Patients typically present with progressive symmetrical weakness with areflexia in bilateral lower extremities, which can be confounded by psychiatric comorbidities. This case is unusual in that the patient had paradoxical hyperreflexia and normal CSF protein levels during her initial presentation, later confirmed to be GBS.

Medullary Thyroid Carcinoma: A Single Institute Experience.

Medullary thyroid carcinoma is a rare tumour that is anatomically located in the thyroid gland but is functionally a neuroendocrine tumour. It is usually a disease of older age group but manifests in a young patient in familial form. It is derived from parafollicular c cells and has a predilection for lymph node metastasis.
