background and objective: chlorella vulgaris is a multi-cellular edible algal species with abundant proteins. extraction of high value protein fractions for pharmaceutical and nutritional applications can significantly increase the commercial value of microalga biomasses. there is no known report on the anticancer peptides derived from the chlorella vulgaris abundant protein. materials and meth...

Antimicrobial peptides represent one of the most promising future strategies for combating infections and microbial drug resistance. Tritrpticin is a 13mer tryptophan-rich cationic antimicrobial peptide with a broad spectrum of activity whose application in antimicrobial therapy has been hampered by ambiguity about its biological target and consequently the molecular interactions necessary for ...

objective: one of the major issues in bone tissue engineering is the design and fabrication of bioactive, bioresorbable porous 3d scaffolds capable of maintaining their structure and integrity over a predictable period of time. one such approach is the fabrication of composite scaffolds. methods: in this study we present fabrication and characterization of novel silk/bioglass-composite scaffold...

Triple-layer omnidirectional reflectors (ODRs) consisting of a semiconductor, a quarter-wavelength transparent dielectric layer, and a metal have high reflectivities for all angles of incidence. Internal ODRs (ambient material's refractive index n >> 1.0) are demonstrated that incorporate nanoporous SiO2, a low-refractive-index material (n = 1.23), as well as dense SiO2 (n = 1.46). GaP and Ag s...

1. introduction some narratologists like kristeva and genette believe that if a text remembers another text, a dialogue has taken place between them and an inter-textual (or trans-textual) relationship has thus been established. some also believe that there is always a relationship between texts. among them, genette accompanied his claims by a theory and opened a new way before the narratologis...

archaeologically, the hybrid and mythological motif of people-scorpion, as presented in both forms of man-scorpion and woman-scorpion, in the horizon of bronze age cultures in the plateau of iran, merely, is reported from the archaeological sites of jiroft in the halil rood basin, southwest iran. in mesopotamia, the people-scorpion is presented as the guardian monster for the gates of dead peop...

casein possesses important physiological and biological properties with regard to promotion of health, as well as prevention of diseases. anticarcinogenic activities, reduction in the risk factors of cardiovascular disease and anticariogenic features have been associated with casein. in addition, casein is known as a source of bioactive peptides. casein-derived peptides have been found to have ...

cyanobacteria are well known for their production of a multitude of highly toxic substances . the genus stigomena is regarded as good candidates for producing biologically active secondary metabolites, which are highly toxic to humans and other animals. the carcass of a dog was found at the shore of lake ali-abad, iran. biomass from the discovery site appeared to be of cyanobacterial nature. we...
