To evaluate the effectiveness of the immunohistochemical staining of B- and T-cell lymphomas with Leu-1 (clone L17F12 CD5 antibody, Becton Dickinson, San Jose, Calif) in formalin-fixed paraffin-embedded sections, we stained 12 specimens reflecting cases of chronic lymphocytic leukemia/small
Estrogen levels in breast tumors of postmenopausal women are as much as 10 times higher than estrogen levels in plasma, presumably due to in situ formation of estrogen. The major source of estrogen in breast cancer cells may be the conversion of estrone sulfate to estrone by the enzyme estrone
We report an injectable hydrogel system that incorporates interferon-α2a (IFN-α2a) for liver cancer therapy. IFN-α2a was incorporated in hydrogels composed of hyaluronic acid-tyramine (HA-Tyr) conjugates through the oxidative coupling of Tyr moieties with hydrogen peroxide (H2O2) and horseradish
This study reports the development of a microfluidic beads-based immunosensor for sensitive detection of cancer biomarker α-fetoprotein (AFP) that uses multienzyme-nanoparticle amplification and quantum dots labels. This method utilizes microbeads functionalized with the capture antibodies (Ab₁) and
Improved methods for attaching radioiodine to monoclonal antibodies have been developed. Ten aryl carbohydrate adducts were synthesized by the reductive amination of a carbohydrate with an aryl amine, using sodium cyanoborohydride as a reducing agent. After purification by chromatography and
Serum albumin (SA) modified and labeled with 131I-tyramine N-1'-desoxysorbitol (131I-TDS) has been shown to localize in tumors [Sinn et al., (1990) Nucl. Med. Biol. Part B 17, 819-827]. We prepared similar TDS complexes labeled with 99mTc and evaluated their potential for tumor imaging.
Inflammation is induced by the expression of cyclooxygenase‑2 (COX‑2), which is an important mediator of chronic inflammatory diseases, such as rheumatoid arthritis, asthma and inflammatory bowel disease. Tribulus terrestris (T. terrestris) is known to have a beneficial effect on inflammatory
Low-molecular-weight synthetic molecules 1 with the general 2-(fluorophenylamino)-4,6-disubstituted 1,3,5-triazine structure and showing anti-inflammatory and anticancer activities were explored. Structure-activity relationship studies demonstrated the importance of the aminopentyl chain, the 3- or
Mechanisms by which gut luminal content regulates secretion and motility are ill understood. We evaluated whether neuroendocrine enterochromaffin (EC) cells act as luminal sensors for a wide variety of nutrients and defined the secretory mechanisms of this process. Pure (98-99%) FACS-sorted human EC
Photodynamic therapy (PDT) is a skin cancer treatment alternative to chemotherapy and radiotherapy. This method exploits three elements: a phototoxic compound (photosensitizer), light source and oxygen. Upon irradiation by light of a specific wavelength, the photosensitizer generates reactive oxygen
The number of cases of erectile dysfunction (ED) caused after radical prostatectomy (RP) prostate cancer treatment is increasing steadily. Although various studies have been conducted for treatment of post-RP ED, there is still a need for more effective methods. A dual growth factor incorporated
Since cyclocytidine (2,2'-anhydro-1-beta-arabinofuranosylcytosine hydrochloride) was introduced as an antineoplastic agent for the treatment of lymphatic leukemia, sinus acceleration and an increase in systemic blood pressure has been reported as its systemic effects in the clinical cases. These
Tyramine, histamine and putrescine are the most commonly detected and most abundant biogenic amines (BA) in food. The consumption of food with high concentrations of these BA is discouraged by the main food safety agencies, but legal limits have only been set for histamine. The present work reports
Albumin dominates the nitrogen and energy resources in blood. However, only limited data is available on its accumulation and catabolism by tumors. This was caused by the lack of suitable radiolabels for long-term follow-up of protein catabolism in vivo. Conventional radiolabels like radioiodine are
