INTRODUCTION: Dermatofibrosarcoma protuberans (Darrier-Ferrand sarcoma, DFSP) is an uncommon tumor. This sarcoma has a tendency to local recurrence, requiring a wide surgical resection. OBSERVATION: We report herein two cases of patients presenting with recurrent dermatofibrosarcoma protuberans after several surgical resections. A wide surgical resection with guided tissue regenaration has been performed in one case, whereas the second case required a skin graft...

Callus protoplasts of a Nicotiana tabacum chlorophyll-deficient mutant were fused with mesophyll protoplasts from one of following five sources: 4 cmsanalogs of tobacco bearing the cytoplasms of N. plumbaginifolia, N. suaveolens, N. repanda, and N. undulata, respectively, as well as wild species N. glauca. In another series of experiments, callus protoplasts from the chlorophyll-deficient genome Su/Su mutant of tobacco were fused with mesophyll protoplasts of the wild species N. glauca and those of a plastome chlorophyll-deficient tobacco mutant...

Transformation of epithelial cells into connective tissue cells (epithelial-mesenchymal transition, EMT) is a complex mechanism involved in tumor metastasis, and in normal embryogenesis, while type II EMT is mainly associated with inflammatory events and tissue regenaration. In this study we examined type II EMT at the ultrastructural and molecular level during the inflammatory process induced by Freund's adjuvant treatment in rat mesenteric mesothelial cells. We found that upon the inflammatory stimulus mesothelial cells lost contact with the basal lamina and with each other, and were transformed into spindle-shaped cells...

A plant transformation vector, pCLKSCLA25 (EU327498), was developed to contain eight cloning sites and the inducible self-excision system which provided an effective approach to eliminate the selectable marker gene(s) from transgenic plants. Upon induction by salicylic acid, the cre gene produced a recombinase that eliminated sequences encoding the selectable marker neomycin phosphotransferase and cre itself. The excision efficiency was 41% in transgenic tomato regenarants. The stilbene synthase gene (vst1) from Vitis vinifera L...

The regenaration of acid and base from the solutions containing metallic salts was achieved by salt splitting method (SSM) using not only anion-exchange membranes (AEM) but also cation-exchange membrane (CEM). In these experiments, while the ion exchange membrane was anion-exchange membrane, acid solutions were used as an anolyte and different salts of potassium were used as a catholyte. In addition to these experiments, while the ion exchange membrane was cation-exchange membrane, base solutions were used as a catholyte and different salts of potassium were used as an anolyte...

PURPOSE OF THE STUDY: The authors describe the therapeutic utilization of separated/isolated autologous growth factors in semiconservative treatment of type III injury to the ankle ligamentous complex. MATERIAL: Between October 2004 and March 2005 a group of 11 patients, two women and nine men, aged 18 to 41 (average, 25.09) years with acute injury to the lateral ligamentous complex of the ankle were treated by plasma rich in growth factors (PRGF) infiltration. On functional radiographic examination, the post-traumatic lateral opening of the tibiotalar intraarticular space was 17...

OBJECTIVE: To study the extraction process of total peony glycoside from Paeonia veitchii Lynvh. METHODS: The extraction process of total peony glycoside with D140 macroporous resin adsorbent was selected with different condence of ethanol for gradient elution. RESULTS: The optimum condence was 35% ethanol. CONCLUSION: The extraction ratio of paeoniflorin was >50%, and the extraction process is simple and convenient...

Glutamine is an important conditionally necessary amino acid in human body. The effort is to establish a new and high efficient L-glutamine production system instead of traditional fermentaion. In this paper, high efficiency of L-glutamine production is obtained by coupling genetic engineered bacterial glutamine synthetase (GS) with yeast alcoholic fermentation system. Glutamine Synthetase gene (glnA) was amplified from Bacillus subtilis genomic DNA with primers designed according to sequences reported in EMBL data bank, then it was inserted into expression vector PET28b, the sequence of glnA was proved to be the same as that reported in the data bank by DNA sequencing...
