This work presents a new approach to fabricating novel polymer nanofiber composites (NFCs) from water solution blends of PVA (hydrolyzed 89%)/ODA-MMT and Na-CMC/ODA-MMT nanocomposites as well as their folic acid (FA) incorporated modifications (NC-3-FA and NC-4-FA) through green electrospinning
Prostate-specific antigen (PSA) and prostatic acid phosphatase (PAP) are well known as specific tumor markers of prostate cancer, but carcinoembryonic antigen (CEA)- and carbohydrate antigen 19-9 (CA19-9)-producing adenocarcinoma originating in the prostate is rare. We report here a case of
Bone cells produce a variety of glycoproteins that contribute to bone health, and function in cell adhesion, stabilizing the extracellular matrix, promoting growth and differentiation, and the induction of apoptosis. Some of these processes appear to be disturbed in arthritis. In this chapter, in
Bone cancer pain (BCP) is common in patients with advanced cancers when the tumors are metastasized to bone. The limited understanding of the complex pathogenesis of BCP leads to the poor effectiveness of clinical treatment. Previous studies have shown that astrocyte-specific connexin (Cx) 43, a
Blood somatomedin levels were assayed biologically in 10 children with Ewing's sarcoma and osteosarcoma and 11 children with other benign tumors. The patients were of the same age. The basal level of somatomedin in malignant bone sarcoma was similar to that in controls. However, after glucose
Bone cells produce many glycoproteins potentially involved in the maintenance of healthy bone tissues. Two cytokines produced in inflamed joints, tumor necrosis factor (TNF)alpha and transforming growth factor (TGF)beta, have previously been shown to alter cellular glycosylation which may
Although the control of bone metastasis has been the focus of intensive investigation, relatively little is known about the molecular mechanisms that regulate or predict the process, even though widespread skeletal dissemination is an important step in the progression of many tumors. As a result,
The use of lectins in histochemical research substantially contributed to the knowledge on carbohydrates. This paper is a preliminary report of findings with lectin histochemistry on normal and pathological bone tissue.
Two new forms of BRP-2, a previously described bone resorptive protein, were purified from ascites fluids obtained from patients with hypercalcemia and metastatic bone cancer. The apparent molecular weights of BRP-2 and of these two proteins were 52,000, 48,000, and 46,000, respectively, as
Serum tumor markers, including carcinoembryonic antigen (CEA), alpha-fetoprotein (AFP), carbohydrate antigen 15-3 (CA 15-3), carbohydrate antigen 19-9 (CA 19-9), cancer antigen 125 (CA 125), and tissue polypeptide antigen (TPA), were measured in 26 patients with skeletal metastases and 11 patients
The histogenesis of Ewing sarcoma, the second most frequent bone tumor in humans, remains controversial. Four Ewing cell lines were analyzed by immunological methods. A panel of antibodies directed to T, B, and myelomonocytic markers gave negative results. Surface antigens recognized on Ewing cells
Management of bone metastasis remains clinically challenging and requires the identification of new molecular target(s) that can be therapeutically exploited to improve patient outcome. Galectin-3 (Gal-3) has been implicated as a secreted factor that alters the bone microenvironment. Proteolytic
