Bone marrow examination frequently demonstrates infiltration with tumor cells in the presence of pancytopenia. • Since metastatic bone marrow involvement from solid tumors may be patchy, a single aspiration is not diagnostic, and at least two aspirates and two biopsies should be performed. •...
For instance, bone/cartilage organoids engineered to express oncogenes or knockout tumor suppressor genes can provide insights into the development and progression of bone and cartilage tumors. Biobanks The potential applications of bone/cartilage organoids in biobanks represent a significant advancement ...
Postoperative CT-scan (F) showed complete resection of the tumor and the frontal bone defect reconstruction using a Titanium mesh plate. Gross total resection (GTR) was performed under general anesthesia via a pterional skin incision, the osseous mass was discovered, and expansion was evaluated. ...
Tumor MarkersBiological浆细胞瘤肿瘤标记生物学The application of immunohistology to the spectrum of plasma cell disorders has yet to be incorporated widely into routine haematology practice. This technique enables the direct visualisation of specific surface and cytoplasmic antigens in the context of the ...

80% cellularity and a large area of necrotic tumor cells occupying 60–70% of the total marrow space consistent with bone marrow necrosis (BMN), the remaining 30–40% of marrow comprised of viable tumor cells, which were intermediate in cell size with round nuclei, indistinct nucleoli and sca...
5.18A); the blurred outlines of cells are seen in a background of amorphous pink material. In some patients with BM necrosis secondary to metastatic carcinoma, an aspirate may show a mixture of intact tumor cells and necrotic tumor and hemopoietic cells. If BM aspirated from one site shows ...
Thus after traversing a distance of 11 to 12 cm, the dissecting instruments must then enter the sella turcica and be able to reach above the sella if a suprasellar tumor is present. The distance may be greater in the presence of acromegaly; therefore, it is important that transsphenoidal ...
developed LOC with integrated biosensor for detecting the inflammatory cytokines such as interleukin-6 (IL-6) and tumor necrosis factor-alpha (TNF-α) from the muscle cells under bacterial lipopolysaccharide (LPS) solution and indium tin oxide array electrodes for electrical stimulation (Ortega et al...
