Histopathological and immunohistochemical features of thyroid carcinoma [PDF]
Archive of Oncology, 2003 Thyroid-specific malignant tumors are derived from follicle cells (papillary and follicular carcinoma), and from parafollicular, calcitonin-producing C-cells (medullary carcinoma). The main criterion for diagnosis of papillary carcinoma is the occurrence

A Diagnostic Dilemma: A Young Boy with Loss of Weight, Pulmonary Infiltrates and Cervical Lymphadenitis [PDF]
Journal of Clinical and Diagnostic Research, 2013 Cervical lymphadenitis is a common finding in young adults in a country like India, where tuberculosis is endemic. We are presenting the case of a young boy who presented with low grade fever, dry cough, weight loss, and a cervical swelling. His chest X-

Chronobiology of Cancer: How Aging Fuels Oncogenesis at the Molecular Level
Aging and Cancer, EarlyView.This graphical abstract illustrates the key biological pathways linking aging with cancer development and progression. In the upper left, cumulative exposure to ultraviolet radiation, toxins, and reactive oxygen species (ROS) causes DNA damage and genomic instability, whereas age‐related decline in repair mechanisms, such as ATM/ATR, BER, and NER ...

Calcitonin-negative medullary thyroid carcinoma: the \u27triple-negative\u27 phenotype
, 2020 Calcitonin-negative medullary thyroid carcinoma is a rare, poorly understood primary neuroendocrine carcinoma of the thyroid characterised by classic medullary thyroid carcinoma morphology without raised serum calcitonin.

Intelligent Micro/Nanorobots for Targeted Interventional Therapy: From Bench to Clinic
Advanced Robotics Research, EarlyView.Zirui Zhang et al. reviewed the application and challenges of mobile nanomachines in interventional therapy. By converting exogenous energy, including chemical, magnetic, optical, and ultrasonic sources, into mechanical forces, micro/nanorobots (MNRs) enable precise actuation at unprecedented scales. Evolving far beyond traditional drug delivery, these

Medullary Carcinoma of the Thyroid
Cancer Control, 2000 Medullary thyroid cancer (MTC) is a distinct C-cell tumor of the thyroid. We review the oncogenesis and management of both sporadic tumors and those tumors arising as part of specific inherited syndromes. The RET proto-oncogene plays a role in the development of inherited forms of MTC and has become important in the clinical management of patients and ...
