Fisheye piezo polymer detector for scanning optoacoustic angiography of experimental neoplasms

Photoacoustics, 2023
A number of optoacoustic (or photoacoustic) microscopy and mesoscopy techniques have successfully been employed for non-invasive tumor angiography. However, accurate rendering of tortuous and multidirectional neoplastic vessels is commonly hindered by ...

Experimental model of micronodular thymic neoplasm with lymphoid stroma

Thoracic Cancer, 2022
AbstractBackgroundMicronodular thymic neoplasm with lymphoid stroma (MNT), a subtype of thymic tumor, is histopathologically characterized by micronodular thymic epithelial cell nests with lymphoid stroma. Despite the distinct histopathology of MNT, its pathogenesis remains unclear.MethodsIn this study, we aimed to examine a thymic tumor harboring ...

Effect of colostomy on experimentally produced neoplasms of the colon of the rat [PDF]

Cancer, 1967
As a means of determining the effect of the fecal stream in the pathogenesis of experimentally produced colonic tumors in Wistar strain rats, simple colostomies were performed in the left colon of 57 female rats at approximately 4 cm above the anus. Fifty-four rats received daily subcutaneous injections, 5 days per week, of the carcinogen 3:2'dimethyl ...

Experimental Modeling of Myeloproliferative Neoplasms

Genes, 2019
Myeloproliferative neoplasms (MPN) are genetically very complex and heterogeneous diseases in which the acquisition of a somatic driver mutation triggers three main myeloid cytokine receptors, and phenotypically expresses as polycythemia vera (PV), essential thrombocytosis (ET), and primary myelofibrosis (PMF).

Abnormal Expression of BTLA and CTLA-4 Immune Checkpoint Molecules in Chronic Lymphocytic Leukemia Patients

Journal of Immunology Research, 2020
Chronic lymphocytic leukemia (CLL) is characterized by the peripheral accumulation of neoplastic B cells and is frequently complicated by the systemic immunosuppression associated with an impairment in B and T lymphocyte activation.

Mathematical methods and models for radiation carcinogenesis studies [PDF]

, 1986
Research on radiation carcinogenesis requires a twofold approach. Studies of primary molecular lesions and subsequent cytogenetic changes are essential, but they cannot at present provide numerical estimates of the risk of small doses of ionizing ...

Driver mutations (JAK2V617F, MPLW515L/K or CALR), pentraxin-3 and C-reactive protein in essential thrombocythemia and polycythemia vera

Journal of Hematology & Oncology, 2017
Background The driver mutations JAK2V617F, MPLW515L/K and CALR influence disease phenotype of myeloproliferative neoplasms (MPNs) and might sustain a condition of chronic inflammation.
