Orbital myeloid sarcoma (chloroma): Report of 2 cases and literature review

open access: yesAmerican Journal of Ophthalmology Case Reports, 2020
Purpose: Myeloid sarcoma (MS) of the orbit is an uncommon condition in occurring in children, generally coupled to myeloproliferative neoplasms. Observations: We describe two rare cases of orbital MS in young boys with aggressive local symptoms but ...

Epigenetic Activation of SOX11 in Lymphoid Neoplasms by Histone Modifications [PDF]

open access: yes, 2011
Recent studies have shown aberrant expression of SOX11 in various types of aggressive B-cell neoplasms. To elucidate the molecular mechanisms leading to such deregulation, we performed a comprehensive SOX11 gene expression and epigenetic study in stem ...

A Rare Case of Intraconal Orbital Schwannoma

open access: yesArchives of Medicine and Health Sciences
Schwannoma is a benign, slow-growing peripheral nerve sheath tumor that originates from Schwann cells. Orbital schwannoma is relatively rare, accounting for only 1% of all orbital neoplasms. Intraconal orbital schwannoma (within the muscle cone) is rarer

Congenital orbital teratoma: a case report with preservation of the globe and 18 years of follow-up

open access: yesBMC Ophthalmology, 2021
Background Congenital orbital teratomas are extremely rare, usually benign neoplasms, comprised of cells originating from all three germ cell layers. Clinically the tumor appears solid, most of the times is intraconal and presents as a rapidly growing ...

In vitro and in silico modelling of ROS1‐positive non‐small cell lung cancer reveals fusion‐dependent tyrosine kinase inhibitor responses

open access: yesMolecular Oncology, EarlyView.
Drug resistance limits treatment success in a subset of lung cancers driven by ROS1 gene alterations. Using patient‐derived cells and computer simulations, we studied three key mutations and how they affect five targeted drugs. The mutations reduced drug effectiveness in different ways by altering protein structure and behavior.

Protein‐Nanoarchitectures for Low‐Field Intracellular Electro‐Immunomodulation

open access: yesAdvanced Functional Materials, EarlyView.
DHQ‐SDH‐mediated binding of AuNPs drives the formation of interconnected, chain‐like nanoarchitectures with enhanced electrical conductivity. These conductive assemblies undergo macrophage uptake and enable low‐field electrical stimulation, promoting M1‐to‐M2 phenotypic switching with decreased iNOS and increased CD206 expression. Such protein‐mediated

Microfluidic Nano‐Assembly of Red‐Blood‐Cell (RBC) Lipids and Components for Engineering Extracellular Vesicles

open access: yesAdvanced Healthcare Materials, EarlyView.
Engineered red blood cell‐derived extracellular vesicles (eRBCEVs) are synthesized via controlled microfluidic assembly from native RBC lipids, enabling tunable encapsulation of proteins, nucleic acids, nanoparticles, and viral vectors. The platform demonstrates reproducible nanoscale architecture, preserved membrane composition, and functional cargo ...

Preoperative transarterial embolization of a recurrent orbital solitary fibrous tumor with significant hypervascularity: a case report

open access: yesBMC Surgery, 2021
Background Orbital solitary fibrous tumors (SFTs) are rare neoplasms. Recurrent, hypervascular, malignant variations of orbital SFTs have recently been noted and can present a surgical challenge.
