Microbial cells are reversibly associated with surfaces in the form of biofilms. Adhesion is mechanism used by microorganisms to bind a surface initially; no biofilm formed without initial adhesion. The aim this work was evaluate efficacy rhamnolipids Pseudomonas aeruginosa Rn19a inhibiting biofilms clinical isolates Escherichia coli I5, E26, Enterococcus faecalis I27 on borosilicate coupons in...

BACKGROUND The Myb-Ets protein encoded by the E26 acute avian leukemia virus is a paradigm for the function of fused transcriptional activator oncoproteins. Myb-Ets transforms hematopoietic progenitor cells (myb-Ets progenitors, MEPs) that can be induced to differentiate into eosinophilic and myeloid cells by the activation of pathways involving Ras and/or protein kinase C. The Ets portion of t...

with regard to bycatch problem, this is the first study of the shrimp trawl bycatch in different depth variation in hormuzgan coastal waters. samples were collected during shrimp season in october 2011 and november 2012. the study area was divided into two regions: hormuz-keshtisoukhte (56°, 27ʹ e/27°, 07ʹ n) to (56°, 18ʹ e/27°, 06ʹ n) and keshtisoukhte-toola (56°, 18ʹ e/27°, 06ʹ n) to (55°, 58...

The changes in the axon and growth cone numbers in the optic nerve of the freshwater turtle Mauremys leprosa were studied by electron microscopy from the embryonic day 14 (E14) to E80, when the animals normally hatch, and from the first postnatal day (P0) to adulthood (5 years on). At E16, the first axons appeared in the optic nerve and were added slowly until E21. From E21, the fibre number in...

E26 is an avian acute leukemia virus with a profound ability to transform multipotent hematopoietic progenitor cells both in vivo and in vitro. Progenitor cells transformed by this virus can be expanded in vitro as undifferentiated clones for up to two months and can also be induced to differentiate into cells of the erythroid, eosinophilic, thrombocytic, and myelomonocytic lineages with reprod...
