OBJECTIVE To evaluate the role of surgery in the management of high-risk gestational trophoblastic neoplasia. STUDY DESIGN Twenty-four (48%) of 50 patients treated with etoposide, methotrexate, actinomycin D, cyclophosphamide and vincristine (EMA-CO) regimen as primary or secondary chemotherapy for high-risk gestational trophoblastic neoplasia between 1986 and 2005 underwent 28 adjuvant surgi...

Amino acid arylamidase I (in earlier work also referred to as leucine aminop~ptidase) appears in the uterine epithelium and is extruded into the uterine lumen in considerable quantities after 3 d p.c. (days post coitum) in the rabbit. In the uterine secretion, the activity of this enzyme shows a very sharp and high peak at 5 d p.c., i .e. in the middle of the preimplantation phase, and it decli...

Plant lectins are cytotoxic and can be used to select for mutants of animal cells that exhibit structural changes in cell surface carbohydrates reflecting glycosylation defects. We isolated eight lectin mutants of Chinese hamster ovary (CHO) cells that appear to represent three different phenotype classes. These lectin mutants were much more sensitive to the cytotoxic action of normal rabbit se...

enzyme efficiency was investigated in the lipase-catalyzed hydrolysis of canola oil in supercritical carbon dioxide (scco2). immobilized lipase from mucor miehie (lipozyme im) was used as the catalyst and the results showed that enzyme efficiency dropped at high pressures indicating a possible change in enzyme microstructure. therefore, scanning electron microscopy (sem) was used as a supplemen...

Introduction: Vaginal atresia is a component of Mayer–Rokitansky–Küster–Hauser syndrome (MRKHS), which includes variable Mullerian duct abnormalities with normal secondary sexual characteristics. Associated renal anomalies are present in about 30% cases(1)
 Objective: To rare variant MRKHS a14-y old female right ovary inguinal hernia and managed bysigmoid vaginoplasty.
 Case Descripti...

Lipolysis is an important metabolic pathway controlling energy homeostasis through degradation of triglycerides stored in lipid droplets and release of fatty acids. Lipid droplets of mammalian cells are coated with one or more members of the PAT protein family, which serve important functions in regulating lipolysis. In this study, we investigate the mechanisms by which PAT family members, peri...

Magnaporthe grisea produces an infection structure called an appressorium, which is used to breach the plant cuticle by mechanical force. Appressoria generate hydrostatic turgor by accumulating molar concentrations of glycerol. To investigate the genetic control and biochemical mechanism for turgor generation, we assayed glycerol biosynthetic enzymes during appressorium development, and the mov...

conclusions results of this study could be used to find suitable targets for inverse metabolic engineering and site-directed mutagenesis to achieve stable and high-level extracellular lipase production in y. lipolytica and other yeasts. results two nucleotide substitutions were found in the extracellular lipase lip2 orfs of y. lipolytica u6 mutant strain compared to the wild-type strain. in thi...

The lysis of cell walls of hemolytic streptococci by a phage-associated lysin has been described. A method is presented for preparing the lysin from Group C streptococcal phage lysates. Following lysis almost all of the cell wall carbohydrate is recovered in solution. This material has the serological reactivity, physical-chemical properties, and values for nitrogen, rhamnose, and glucosamine s...

background: coronary artery disease (cad) is one of the leading causes of death and disability around the world. interaction between genetic and environmental factors determines susceptibility of an individual to develop coronary artery disease . lipoprotein lipase (lpl) play an important role in the metabolism of hdl-c ( high density lipoprotein cholesterol ), ldl-c (low density lipoprotein ch...
