On the coherent behavior of pancreatic beta cell clusters [PDF]
, 2014 Beta cells in pancreas represent an example of coupled biological oscillators which via communication pathways, are able to synchronize their electrical activity, giving rise to pulsatile insulin release. In this work we numerically analyze scale free self-similarity features of membrane voltage signal power density spectrum, through a stochastic ...

Physical Confinement and Cell Proximity Increase Cell Migration Rates and Invasiveness: A Mathematical Model of Cancer Cell Invasion through Flexible Channels [PDF]
, 2022 Cancer cell migration between different body parts is the driving force behind cancer metastasis, which is the main cause of mortality of patients. Migration of cancer cells often proceeds by penetration through narrow cavities in locally stiff, yet flexible tissues. In our previous work, we developed a model for cell geometry evolution during invasion,

Eruptive Xanthomata Manifesting in Tattoos
JEADV Clinical Practice, EarlyView.ABSTRACT Eruptive xanthomata represent a rare, but important pruritic dermatosis for which an accurate diagnosis can prevent life‐threatening complications. We present the case of a 29‐year‐old female with no prior medical history who presented to clinic for evaluation of a pruritic papular eruption of 2 weeks' duration.

Surface activity of cancer cells: the fusion of two cell aggregates [PDF]
arXiv, 2021 Although a good comprehension of how cancer cells collectively migrate by following molecular rules which influence the state of cell-cell adhesion contacts has been generated, the impact of collective migration on cellular rearrangement from subcellular to supracellular level remains less understood.

Cell-to-cell variation sets a tissue-rheology-dependent bound on collective gradient sensing [PDF]
PNAS (2017), 2017 When a single cell senses a chemical gradient and chemotaxes, stochastic receptor-ligand binding can be a fundamental limit to the cell's accuracy. For clusters of cells responding to gradients, however, there is a critical difference: even genetically identical cells have differing responses to chemical signals.

Journal of Experimental Medicine, 2018 Langerhans cell histiocytosis (LCH) is an inflammatory myeloid neoplasia characterized by granulomatous lesions containing pathological CD207+ dendritic cells (DCs) with constitutively activated mitogen-activated protein kinase (MAPK) pathway signaling ...

An unusual case of intertrigo in an adult caused by purely cutaneous Langerhans cell histiocytosis [PDF]
, 2016 We report a case of persistent intertrigo in an adult, eventually diagnosed as cutaneous Langerhans cell histiocytosis (LCH). It is known that LCH has a predilection for intertriginous areas, however purely cutaneous disease as in our case, is uncommon ...

Langerhans Cell Histiocytosis of the Tonsil
Balkan Medical Journal, 2022 Langerhans cell histiocytosis (LCH) is a rare disease that is characterized by clonal neoplastic proliferation of the dendritic Langerhans cells. LCH presents either with solitary or multiple organ involvement.1,2 The most commonly affected organs include the bones, skin, and pituitary gland; the hematopoietic system, lymph nodes, and lungs are rarely ...
