Mathematical models for order of mutation problem in myeloproliferative neoplasm: non-additivity and non-commutativity [PDF]

arXiv, 2023
In some patients of myeloproliferative neoplasm, two genetic mutations can be found: JAK2 V617F and TET2. When one mutation is present or not, the other mutation has different effects on regulating gene expressions. Besides, when both mutations are present, the order of occurrence might make a difference.

Lung Transplantation in Controlled Donation after Circulatory-Determination-of-Death Using Normothermic Abdominal Perfusion

Transplant International
The main limitation to increased rates of lung transplantation (LT) continues to be the availability of suitable donors. At present, the largest source of lung allografts is still donation after the neurologic determination of death (brain-death donors ...

Order-of-mutation effects on cancer progression: models for myeloproliferative neoplasm [PDF]

arXiv, 2023
We develop a modeling framework for cancer progression that distinguishes the order of two possible mutations. Recent observations and information on myeloproliferative neoplasms are analyzed within our framework. In some patients with myeloproliferative neoplasms, two genetic mutations can be found, JAK2 V617F and TET2.

Incidentally Detected Malignancies in Lung Transplant Explants

Transplantation Direct, 2019
Background. Active malignancy diagnosed within 5 years is an absolute contraindication for lung transplantation. In this study, we evaluated the rate of incidental malignancies detected in explanted lungs at our institution and assessed the ...

Some correlations between eight types of malignant neoplasms: A hint from cancer dynamics of 31 European countries in 20 years [PDF]

Network Biology, 2017
In present study, the data of standardised death rates of malignant neoplasms per 100000 inhabitants in 31 European countries during 1994-2013 were used to analyze linear correlations between eight types of cancers in terms of induced death rates.

Lymphoproliferative Neoplasms of the Lung: A Review

Archives of Pathology & Laboratory Medicine, 2013
Context.—Diagnosis and classification of lymphomas are based on the morphologic, immunologic, and genetic features that the lesional cells share with their normal B and T lymphocyte counterparts. Primary pulmonary lymphomas account for 0.3% of primary lung neoplasms and less than 0.5% of all lymphomas.Objective.—To describe and summarize the clinical ...

The dual nature of TDC – bridging dendritic and T cells in immunity

FEBS Letters, EarlyView.
TDC are hematopoietic cells combining dendritic and T cell features. They reach secondary lymphoid organs (SLOs) and peripheral organs (liver and lungs) after FLT3‐dependent development in the bone marrow and maturation in the thymus. TDC are activated and enriched in SLOs upon viral infection, suggesting that they might play unique immune roles, since
