The present study was carried out to estimate genetic variability parameters for some traits such as pods per plant, cell membrane stability, one thousand kernel weight, flowering period, grain filling period, chlorophyll content, relative water content, leaf excised water content, seed per pod and pod length, in 16 winter rapeseed genotypes. Statistical analysis showed significant differences ...

in the current work, graphene oxide (go) samples were prepared at room temperature from graphite flakes using a modified hummer's method to produce metal-free electrocatalysts. the effect of the duration of the oxidation process on the structural, chemical and physical characteristics of the go samples was evaluated using x-ray diffraction (xrd), fourier transform infrared spectroscopy (ftir), ...

amniotic epithelial cells (aecs) possess unique characteristics, which make them a suitable source for cell-based therapeutic strategies. aecs have stem cell properties with low-immunogenicity (due to expressing hla-g molecule and absence of mhc class i and ii antigens) and no ethical problems, as well as availability in sufficient numbers, which can be obtained from a placenta. we have recentl...

an essential requirement for an operating pem fuel cell is providing proper water content in the membrane. to avoid water flooding an appropriate water balance is required. here, an analytic model of a planar membrane humidifier for pem fuel cell is proposed where the effect of dimensional parameters includes membrane thickness, membrane area and channel hydraulic diameter are investigated. a n...

the microphase separation of hydrated perfluorinated sulfonic acid membrane nafion was investigated using dissipative particle dynamics (dpd). the nafion as a polymer was modelled by connecting coarse grained beads which corresponds to the hydrophobic backbone of polytetrafluoroethylene and perfluorinated side chains terminated by hydrophilic end particles of sulfonic acid groups [1, 2]. each f...

conclusions the results presented herein provided insight into a possible explanation for the modes of action of essential oils on l. monocytogenes. the outcome of the present study may aid the food industry in locating the most promising potential anti-listerial agents from edible seaweed sources to control l. monocytogenes and also in facilitating their application in food processing and pres...

the major limitation in the application of bioactive molecule is their low permeation across plasma membrane. in 1988 it was discovered, that a natural polycationic protein, the trans-acting activator of transcription (tat) of the human immunodeficiency virus (hiv-1), passed very efficiently through cell membrane of cultured mammalian cells. tat became known as the first cell penetrating peptid...

background: the monoclonal antibody, c595, against breast cancer cell line was conjugated with cyclic anhydride gadolinium-diethylenetriaminepenta-acetic acid (gd-cdtpaa) to produce gd-dtpa-c595 and used as specific breast cancer cell line (mcf-7) contrast agents in magnetic resonance imaging (mri).  methods: after incubation of breast cancer cell line (mcf-7), with different contrast agents (g...

Objective(s): Umbilical cord blood is a good source of the mesenchymal stem cells that can be banked, expanded and used in regenerative medicine.  The objective of this study was to test whether amniotic membrane extract, as a rich source of growth factors such as basic-fibroblast growth factor, can promote the proliferation potential of the umbilical cord mesenchymal stem cells. Materials and ...
