during early neurogenesis, the floor plate plays an essential role(s) in the differentiation of the ventral portion of neural tube. in this study, we detected the specific distribution of unique glycoconjugate during the floor plate differentiation. formalin fixed paraffin sections of balb/c mice (10-14 embryonic days) were processed for histochemical studies using horseradish peroxidase-labell...

this study aimed at the frequency and type of using cell-phone by high school students. the research method used was a descriptive-survey one. the statistical society included all the high school students in mazandran in 2010-11 academic year. the sample was chosen through multi-stage stratified random sampling method and 383 subjects were selected based on kerjecie and morgan's table. a r...

the primary cilium which is an organelle in nearly every cell in the vertebrate body extends out of the cell surface like an antenna and is known as cell sensor of mechanical and chemical stimuli. in previous numerical simulations, researchers modeled this organelle as a cantilevered beam attached to the cell surface. in the present study, however, we present a novel model that accommodates for...

background:the zinc-finger x linked (zfx) gene encodes a transcription factor that acts as a regulator of self-renewal of stem cells. due to the role of zfx in cell growth, understanding zfx protein-protein interactions helps to clarify its proper biological functions in signaling pathways. the aim of this study is to define zfx protein-protein interactions and the role of zfx in cell growth. m...

background: none-chemical distant cellular interactions (ncdci) are among the unexplained issues in cell biology. one example of such interactions is the biophoton-induced growth. in this process, photon emissions from one cell can induce mitosis in other cells while they are chemically separated. this effect is evident among many species. hypothesis: it is hypothesized that some simple but uni...

Viruses are obligatory intracellular parasites that use cell proteins to take the control of the cell functions in order to accomplish their life cycle. Studying the viral-host interactions would increase our knowledge of the viral biology and mechanisms of pathogenesis. Studies on pathogenesis mechanisms of lyssaviruses, which are the causative agents of rabies, have revealed some important ho...
