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 ...

Tobacco experimental model to induce urinary bladder neoplasms [PDF]
Revista do Colégio Brasileiro de Cirurgiões, 2014 OBJECTIVE: to develop an experimental model of exposure to tobacco burning (cigarette) products to assess the effects of its chronic use in relation to cancers of the bladder. METHODS: the animals were chronically exposed to the burning tobacco products in a semi-open chamber to simulate smoking. Thirty young Wistar rats were divided into two groups:

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).

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 the limited aperture size, narrow bandwidth and insufficient angular coverage of commercially ...

Experimental and Clinical Use of the YAG Laser in the Management of Pulmonary Neoplasms
Annals of Surgery, 1984 Animal experiments were performed with evaluation of the use of the neodymium-YAG (yttrium-aluminum-garnet) laser in the trachea, bronchi, and pulmonary parenchyma. Histologic evaluation of incisions into the lung was assessed by multiple sections over a 5-week period and comparisons were made of incisions closed with chronic catgut or coagulated with ...

Studies of Human Papovavirus Tumor Antigen in Experimental and Human Cerebral Neoplasms [PDF]
Canadian Journal of Neurological Sciences / Journal Canadien des Sciences Neurologiques, 1976 SUMMARY:Three types of papovaviruses (JC, BK, and SV40) have been isolated from man. All three are oncogenic in hamsters, cause frequent infection of man, and share a common T antigen. Augmentation of the expression of T antigen by in vitro cultivation of SV40-induced tumors of hamsters suggested that growing human brain tumors in vitro might provide ...

Experimentally Produced Neoplasms in the Frog.
Experimental Biology and Medicine, 1930 It has been known that the frog egg on the stage of the second polar spindle-metaphase passes into a resting period, awaiting fertilization. Under natural conditions this lasts for only a few hours, but can be delayed up to 3 days without impairing perceptibly the vigor of the egg. After a further delay of 2 days, however, the eggs are dead.

Collagen Matrix in Development and Progression of Experimentally Induced Respiratory Neoplasms in the Hamster [PDF]
Toxicologic Pathology, 2001 Intratracheal instillations of 7H-dibenzo(c, g)carbazole (DBC), a tobacco smoke component, into Syrian golden hamsters, resulted in preneoplastic lesions and benign and malignant respiratory neoplasms. Neoplastic progression was associated with specifi cchanges in the extracellular matrix (ECM), dependent on the stage of tumor development. DBC-induced

Comparison of MRI, CT and bone scintigraphy in metastases of experimental neoplasm.
The Tohoku Journal of Experimental Medicine, 1991 We compared MRI, CT and bone scintigraphy in the examination of experimentally produced metastatic bone tumors. Three Japanese white rabbits with VX-2 bone tumor were used. T1 weighted (T1W) and T2 weighted (T2W) images were obtained in each MRI examination. All the tumors distributed from the bone marrow to the extraosseous region. T2W images were the
