The effects of aromatase inhibitors 4-hydroxyandrostenedione (4-OHA), CGS 16949A, and CGS 20267, and of the antiestrogen tamoxifen (TAM), were studied on the growth of human breast carcinoma in a nude mouse model. To simulate the postmenopausal breast cancer patient, tumors were formed from inoculates of MCF-7 cells transfected with the human aromatase gene to provide a source of non-ovarian es...

Antimycin A (AMA) inhibits succinate oxidase and the mitochondrial electron transport chain between cytochrome b and c. Here, we report on the effects of mitogen-activated protein kinase (MAPK) inhibitors on AMA-treated calf pulmonary artery endothelial cells (CPAEC) in relation to cell death, reactive oxygen species (ROS) and glutathione (GSH). AMA inhibited the growth of CPAEC and also induce...

Objective: The use of bioactive extracellular matrix (ECM) grafts such as amniotic membranes is an attractive treatment option for enhancing wound repair. In this study, the concentrations, activity, and distribution of matrix components, growth factors, proteases, and inhibitors were evaluated in PURION® Processed, micronized, dehydrated human amnion/chorion membrane (dHACM; MiMedx Group, Inc....

BACKGROUND Prostate cancer is the most common male cancer and one of the top causes of male cancer-related death. Most patients with prostate cancer respond to initial androgen deprivation therapy before progressing to castration-resistant prostate cancer (CRPC) and eventually developing bone metastases. Growth of prostate cancer metastases in the bone microenvironment produces numerous factors...

Initiation and Growth of Uroliths Urolith formation, dissolution, and prevention involve complex physical processes. Major factors include: 1) supersaturation resulting in crystal formation, 2) effects of inhibitors of crystallization and inhibitors of crystal aggregation and growth, 3) crystalloid complexors, 4) effects of promoters of crystal aggregation and growth, and 5) effects of non-crys...

Pichia membranifaciens KS47-1 is capable of growing on hydrolysate containing high concentrations of acetate and other growth inhibitors. To reveal the acetate-resistant associate genes of strain KS47-1, we present the 11.4-Mb draft genome sequence.

PURPOSE Conjunctival melanoma (CM) is a rare but lethal form of cancer. Similar to cutaneous melanoma, CM frequently carries activating mutations in BRAF and NRAS. We studied whether CM as well as conjunctival benign and premalignant melanocytic lesions express targets in the mitogen-activated protein kinase (MAPK) and AKT pathways, and whether specific inhibitors can suppress CM growth in vitr...

the cross-border symposium on hepatitis c, entitled “why treating now?” was held on 15th may 2013 during the 5th international tehran hepatitis congress. the present report summarizing communicated insights during this symposium is intended to help health care providers to make well-informed decisions when treating patients with chronic hepatitis c (chc). since today’s evolving science of hepat...

schizophrenia and various neurological disorders have some signs and symptoms. visual hallucinations are one of such disorders. the related studies in some diseases for example parkinson disease and lewy body dementia indicate that acetylcholine (ach) plays a significant role in neuropsychiatric manifestation and its association with visual hallucination; therefore, visual hallucinations occur ...
