MicroRNAs (miRNAs) are single-stranded, non-coding RNA
molecules, which can regulate the translation of target proteins and
thereby control biological functions. They qualify as diagnostic
markers and can help to detect diseases earlier. In case o
f a disease
the concentrations of specific miRNAs which are characteristic for
it do vary in quantity. For the detection of miRNA we are using a
surface plasmon resonance (SPR) biosensor, which allows to
measure interactions of molecules at an interface in real-time. For
this, thiolated LNA capture probes are immobilized on the gold
chip.
This research investigates the actual beginning of experimental animation films and
their main directions. The research also reviews the most important pioneers of abstract
experimental animation in both Europe and the U. S. A. such as Leopold Surv
age, Viking
Eggeling and Hans Richter, on the one hand, and the most important film productions and
the techniques used, on the other. We move on after that to the most wellknown figures of
the pictorial school in Europe as Lotte Reinger, Berthold Bartosch and Alexander
Alexeieff.
The research moves on to take up the review of the contemporary experimental
directions which began in the early 1950's and continued up to the present time, the
directions which produced significant figures and experiments of paramount importance in
the history of animation , such as Walter Disney, Ivan Vano, Osamo Tezuka, Norma
Mclaren in addition to John Halas. These approaches shape the future of animation. The
present research sheds light on the significance of both previous (earlier) experiments and
the prospect of animation films.
Hepatocellular carcinoma (HCC) is a common malignancy and the
leading cause of death worldwide, due to late detection and high
recurrence rates. Osteopontin (OPN) has various functions,
including prevention of apoptosis and modulation of angiogene
sis
which lead to tumor formation and progression, although the exact
mechanisms for the development of cancer are still unknown.
