World Journal of Surgical Oncology, 2006 AbstractBackgroundMerkel cell carcinoma (MCC) is an unusual primary neuroendocrine carcinoma of the skin. MCC is a fatal disease, and patients have a poor chance of survival. Moreover, MCC lacks distinguishing clinical features, and thus by the time the diagnosis is made, the tumour usually have metastasized.

Neuromorphic Devices and Computing for Sensing, Memory, and Control
Advanced Science, EarlyView.This review introduces neuromorphic devices made from diverse materials. These devices mimic neuronal functions and architectures and, when integrated with artificial or biological computing, can form closed loops with neurons for pressure, optical, acoustic, and biochemical sensing and modulation.

Archives of Pathology and Laboratory Medicine, 2010 Abstract Merkel cell carcinoma is a rare, highly aggressive neuroendocrine cutaneous neoplasm with a variable clinical presentation. Histologically, it is a predominantly dermal-based lesion composed of monotonous small round cells with scanty cytoplasm, often difficult to differentiate from small round cell tumors, metastatic small ...

Merkel cell carcinoma with axillary metastasis; a case report of a rare disease
Journal of Oncological Sciences, 2018 Merkel cell carcinoma is a rare primer neuroendocrine carcinoma of the skin. It is an extremely aggressive tumor. This rare carcinoma is seen with high local and regional recurrence ratios and distant metastasis.

Advanced Science, EarlyView.Human vellus pilosebaceous units (PSUs) remain uncharted. This single‐nucleus atlas reveals coordinated remodeling of the aging PSU niche: reduced bulge stem cell representation with altered regenerative programs, increased representation of a stress‐responsive channel+ epithelial state, enhanced androgen‐responsive sebaceous programs, reduced ...

Merkel Cell Polyomavirus in Respiratory Tract Secretions
Emerging Infectious Diseases, 2009 Merkel cell polyomavirus (MCPyV), associated with Merkel cell carcinoma, was detected in 27 of 635 nasopharyngeal aspirate samples by real-time PCR. MCPyV was more commonly found in adults than in children.

Merkel Cells in Somatosensation [PDF]
Chemosensory Perception, 2008 Merkel cells are rare epidermal cells whose function in the skin is still debated. These cells localize to highly touch-sensitive areas of vertebrate epithelia, including palatine ridges, touch domes and finger tips. In most cases, Merkel cells complex with somatosensory afferents to form slowly adapting touch receptors; it is unclear, however, whether
