Title: About OMICS Group


1
About OMICS Group
  • OMICS Group International is an
    amalgamation of Open Access publications and
    worldwide international science conferences and
    events. Established in the year 2007 with the
    sole aim of making the information on Sciences
    and technology Open Access, OMICS Group
    publishes 400 online open access scholarly
    journals in all aspects of Science, Engineering,
    Management and Technology journals. OMICS Group
    has been instrumental in taking the knowledge on
    Science technology to the doorsteps of ordinary
    men and women. Research Scholars, Students,
    Libraries, Educational Institutions, Research
    centers and the industry are main stakeholders
    that benefitted greatly from this knowledge
    dissemination. OMICS Group also organizes
    300 International conferences annually across the
    globe, where knowledge transfer takes place
    through debates, round table discussions, poster
    presentations, workshops, symposia and
    exhibitions.

    the globe annually with the support of more than
    1000 scientific associations and 30,000 editorial
    board members and 3.5 million followers to its
    credit.
  • OMICS Group has organized 500 conferences,
    workshops and national symposiums across the
    major cities including San Francisco, Las Vegas,

  • NT-3, NT-4/5
  • Problems due to large peptide molecule
  • No penetration of B.B.B.
  • Poor oral pharmacokinetic profiles
  • Immune reactions

PC12 cells used for Screening neurotrophic/neurop
rotective/cytotoxic compounds
The PC12 cell line was derived from rat
pheochromocytoma, a tumor arising from chromaffin
cells of the adrenal medulla. It is a useful
model for studying cell signaling for at least
two reasons (i) There are few growth factors,
neurotrophins, and hormones to which it does not
respond and (ii) distinct responses of
differentiation, proliferation, and survival can
all be assessed independently.

The Principles for Screening Neurotrophic/Neuropro
tective Compounds in Rat Cortical Neurons
Neurotrophic compounds can promote neurite
outgrowth, which improves the status of neurons.
Neuroprotective compounds can retard toxic
factor-induced cell death in primary cultured
neurons.

PC12 cells were cultured in 24-well plates in
DMEM 10 HS and 5 FBS for 24 h at a density of
2x103 cells/cm2, and then medium was changed to
DMEM 2 HS and 1 FBS containing 1 and 2.
After 4 days cells with neurites were counted.
