Twenty-seven otherwise healthy patients with localized sarcoma were examined to determine if glucose intolerance can be detected before the appearance of clinical signs of cachexia. No patient had lost weight or demonstrated severe malnutrition. Fasting plasma samples for glucose, insulin, glucagon,
This study characterizes the actions of insulin and parathyroid hormone (PTH) on the glucose transport system in the rat osteogenic sarcoma cell line UMR 106-01, which expresses a number of features of the osteoblast phenotype. Using [1,2-3H]2-deoxyglucose (2-DOG) as a label, UMR 106-01 cells were
The morphological features of epithelioid sarcoma may closely mimic those of epithelial neoplasms, such as squamous cell carcinoma, mesenchymal tumors, such as benign fibrous histiocytoma, and nonneoplastic lesions, such as granuloma annulare. Immunohistochemistry, particularly for epithelial
A glucose binding fraction was obtained by sucrose gradient centrifugation and Sephadex G-200 chromatopgraphy from confluent normal cells and Rous sarcoma virus-transformed fibroblasts. It was more or less loosely bound to the membrane fraction, most strongly in sarcoma cells, and most loosely in
Fluorodeoxyglucose (FDG), labeled with F-18, is a glucose analog that accumulates in cells in proportion to the rate of glucose metabolism, and increased carbohydrate metabolism has been recognized as a feature of malignant cells versus normal cells. In addition, it permits the detection of
A cerebrospinal fluid sample collected from the cerebellomedullary cistern of a 10-year-old Shetland Sheepdog with a recent history of seizures was submitted for fluid analysis and cytologic examination. Key findings included a total nucleated cell count of 520/microL (reference interval 0-5
Refined methods for maintaining specific functions of isolated hepatocytes under xeno-free and chemical defined conditions is of great importance for the development of hepatocyte research and regenerative therapy. Laminins, a large family of heterotrimeric basement membrane adhesion proteins, are
To determine whether occult eosinophil degranulation occurs in lymphomas, the authors performed immunohistologic and cytochemical studies on cryostat sections from 25 consecutive lymph node biopsies. A glucose-oxidase immunohistochemical technique was employed with a murine monoclonal antibody
Multiple intravenous injections (30 micrograms, ten times) in ICR mice of trehalose dimycolate and glucose monomycolate from Nocardia rubra, containing C36-48 mycolic acids, showed a prominent antitumor effect on a subcutaneously implanted sarcoma-180, an allogeneic sarcoma of mice with a
Plasma amino acid concentrations were measured in fasting nontumor bearing (NTB) and tumor bearing (TB; methylcholanthrene induced sarcoma) male Fischer F344 rats during infusion of 0.9% NaCl solution or glucose at 3.72 or 13.05 mumol/100 g total body weight (TBW)/min. The animals were studied when
The most commonly used positron emission tomography (PET) tracer in clinical practice, fluorine-18 fluorodeoxyglucose ( (18)F-FDG) is a glucose analogue that directly gains entry in excess into tumor cells. It is therefore sensitive for the detection of early bone marrow involvement prior to any
The avid consumption of glucose with concomitant lactate production by malignant cells, even under aerobic conditions, is called the Warburg effect, or aerobic glycolysis. This metabolic state is a final common pathway that apparently serves various invasive purposes. As most invasive tumours
High-resolution cross-sectional imaging improved dramatically the diagnosis and therapy management of oncological patients, although several questions remained open, primarily concerning the exact initial staging, the differential diagnosis of recurrent tumors, and therapy management. Positron
Is it possible to eliminate metastasized cancer cells from ovarian cortex fragments prior to autotransplantation without compromising the ovarian tissue or follicles?Ex vivo pharmacological inhibition of YAP/TAZ by Verteporfin enabled us to efficiently
