Journal of Applied Oral Science, 2011 The Human Papillomavirus (HPV) has been strongly implicated in development of some cases of oral squamous cell carcinoma (OSCC). However, the immunological system somehow reacts against the presence of this virus.

Langerhans’ cell histiocytosis diagnosed due to dermatological perianal lesion
Journal of Coloproctology, 2017 Langerhans’ cell histiocytosis is a rare disease characterized by proliferation of Langerhans cells in the body. It affects mainly males, predominantly in childhood. Ulcerated plaques are one of the cutaneous forms of presentation.

BMC Immunology, 2004 Background The Eph receptors are the largest receptor tyrosine kinase family. Several family members are expressed in hematopoietic cells. Previously, the expression of a member of this family, EphA2, was identified on dendritic like cells in tonsils. We

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.

An insight into the origin, distribution, and techniques of demonstration of Langerhans cells
SRM Journal of Research in Dental Sciences, 2017 Langerhans cells (LCs), first described by Paul Langerhans, a German physician in 1868, are dendritic cells predominantly observed in the suprabasal layers of the epidermis and the oral epithelium.

Modeling of reaction-diffusion transport into a core-shell geometry [PDF]
arXiv, 2018 Fickian diffusion into a core-shell geometry is modeled. The interior core mimics pancreatic Langerhan islets and the exterior shell acts as inert protection. The consumption of oxygen diffusing into the cells is approximated using Michaelis-Menten kinetics. The problem is transformed to dimensionless units and solved numerically.

Recent advances in photopharmacology: Harnessing visible light‐activated azobenzene photoswitches
Responsive Materials, EarlyView.This review highlights strategies for the synthesis of visible light‐responsive azobenzenes and their applications in the emerging photopharmacology. Furthermore, we identify the current challenges and discuss future opportunities for rational design in photopharmacology that is triggered by the excitation light in “phototherapeutic window” of 650–900 ...

Self-assembly, Buckling & Density-Invariant Growth of Three-dimensional Vascular Networks [PDF]
arXiv, 2019 The experimental actualisation of organoids modelling organs from brains to pancreases has revealed that much of the diverse morphologies of organs are emergent properties of simple intercellular "rules" and not the result of top-down orchestration. In contrast to other organs, the initial plexus of the vascular system is formed by aggregation of cells
