Circulating tumor cells (CTCs) are essential for the establishment of distant metastasis. Numerous studies have characterized CTCs as metastatic precursors; however, the molecular nature of CTCs has not been completely revealed yet due to the low number of CTCs in the blood stream. As an alternative approach, we developed a long-term suspension cell culture model using human breast cancer cell ...

Conditioned medium from mesophyll cell-suspension cultures of Zinnia eregans 1. has striking effects on cell expansion and tracheary element differentiation when applied to cultures of freshly isolated mesophyll cells. These effects include (a) induction of early cell expansion, (b) delay in differentiation by 48 h or more, (c) reduction in the synchrony of differentiation, and (d) early format...

MicroEncapsulated Phase Change Materials (MEPCM) are green materials which could be used for thermal energy saving applications in buildings as a non-pollutant method for environmental. PCMs could passively reduce peak cooling loads in hot seasons because of their high energy storage capacities at a constant temperature. Purpose of this paper is manufacturing Microencapsulated PCM (MPCM) pr...

carboxymethyl cellulose (cmc)-polyvinyl alcohol (pvoh) blend film, containing 0-10% cellulose nanowhiskers (cnw), was produced through casting method, while physical properties of the films being investigated. cmc-pvoh-cnw nanocomposites, were prepared with a diluted suspension of cellulose nanowhiskers. nanowhiskers suspension was prepared through acid hydrolysis of cotton linter by sulfuric a...

introduction: depressive disorder is a prevalent psychiatric disorder, which affects 21% of the world population. the presently using drugs can impose a variety of side-effects including cardiac toxicity, hypopiesia, sexual dysfunction, body weight gain, and sleep disorder. during the last decade, there is a growing interest in the therapeutic effects of natural products on mental disorders. am...

introduction: hela cell is a widely studied cell line derived from human cerzix adenocarcinoma. the cells are epithelial - like in morphology and susceptible to polio viruses and adenovirus type 5. hela cells are usually as monolayer for isolation and propagation of some human viruses, as well as for the expression of recombinant proteins, including hepatitis b surface antigen. the aim of this ...
