Chromanone derivatives demonstrate remarkable cytotoxity against a varieties of cancer cell lines. Novel 9-[hydroxy(substitutedphenyl)methyl]-2,2-dimethyl-2,3,8,9- tetrahydro-4H,10H-pyrano[2,3-f]chromene-4,10-diones as Glyasperin analogues were synthesized in four steps from known 4-chromone 1. The key step was the preparation of chromane dione 5a by regioselective intramolecular c...

It is additionally employed for other health conditions including colds, diarrhea and as an insecticide in Bangladesh. The aim of the present study was to investigate the antibacterial and cytotoxic activities of different extracts of Grewia paniculata. MATERIALS AND METHODS ...

Cholecystokinin (CCK) is a multifunctional regulatory peptide, which acts through two main subtypes of receptors, named CCK-A and CCK-B. Evidence indicates that CCK modulates cell proliferation in various tissues in a paracrine manner, and proofs are available of the presence of CCK in both adrenal glands and thymus. Hence, we have investigated the possible mitogenic action of this peptide on t...

A patient with malignant melanoma of the oral cavity who lived for a long period despite developing liver metastasis is presented. An 81-year-old female was referred to our hospital because of a pigmented tumor of the lower gingiva. Under the clinical diagnosis of malignant melanoma, she underwent bilateral functional neck dissection and marginal mandiblectomy. Histological diagnosis of the ope...

BACKGROUND Systemic treatment of head and neck squamous cell carcinoma (HNSCC) includes a variety of antineoplastic drugs. However, drug-resistance interferes with the effectiveness of chemotherapy. Preclinical testing models are needed in order to develop approaches to overcome chemoresistance. - METHODS Ten human cell lines were obtained from HNSCC, including one with experimentally-induced...

Primary mediastinal B cell lymphoma (PMBL) is characterized by specific molecular hallmarks including the expression of B Cell Lymphoma factor 6 (BCL6) and the presence of the activated Signal Transducers and Activators of Transcription factor 6 (STAT6). Recently we have shown that combined targeting of BCL6 and activated STAT6 by specific chemical inhibitors in PMBL resulted in additive effica...

Canine transmissible venereal tumor (CTVT) is a malignant of the genital organs that transmitted to dogs through implantation cells in mucous membranes during mating, licking, biting, fighting, or various forms direct contact. The case animal 1.5 years old female local dog with body weight 10.45 kg complaint lump vaginal area for last 2 months and blood dripping from her vagina. Based on anamne...

Background: Infertility problem affects young couples. One of the known causes of spermatogenic disorder is chemotherapy in patients with cancer. Since dividing cells are mainly affected by anticancer drugs, the aim of the present study is to investigate the preventive effect of GnRH antagonist on spermatogenic defect produced by anticancer drug. Materials and Methods: In the present study 30 a...

Primary gastric lymphoma (PGL) is not a common cancer and account for 10% of malignant lymphoma and 5% of gastric cancer. The correlation with Helicobacter pylori (H. pylori) infection with mucosa associated lymphoepithelial tumor (MALT) is now well documented and some of the low grade MALT can be cured sorely by triple agent eradication therapy. The most common type of PGL is diffuse large B c...
