here's a look at what's coming up in the july two thousand thirteen issue
of Jove, the journal of visualized experiments. this month we take a
dip in the zebrafish tank and use this classical laboratory model to study
muscle function specifically our authors measured force generation during trunk
muscle contraction in zebrafish larvae
this is done by attaching the larvae to a force transducer
and a length controller.
Our authors then apply an electrical field to stimulate the muscle fibers and
and then determine the force generating capacity of the larval muscles
this gives a useful measure of muscle function and overall health
another group combines farming with pharma
and demonstrates a transgenic plant based system for expressing bio
pharmaceuticals on an agricultural scale
our authors agroinfiltrate plant leaves with viral vectors to induce
high-level transient expression of recombinant proteins
this can lead to large-scale pharmaceutical production to meet
increasing worldwide demands
Moving on to JoVE's brand new behavior section we focus on aggression a natural
response to intruders in virtually all animals
our others demonstrate the resident intruder paradigm in rats and
illustrate various natural behaviors against intruders
including social exploration
lateral threats
and attack
In JoVE clinical and translational medicine, we focus on psoriasis a chronic
inflammatory skin disease
our others demonstrate Goeckerman regimen
a psoriasis treatment that applies ultraviolet B phototherapy followed
by crude coal tar developed in nineteen twenty five by the american dermatologist
William H Goeckerman
this treatment has an excellent safety profile compared to immune
suppressing drugs
and is extremely effective in treating psoriasis
finally and JoVE bioengineering we highlight the incredible versatility of
nucleic acids beside storing information that directs countless biological
processes nucleic acids can be programmed to self-assembled into
two-dimensional and three-dimensional structures in this video our authors use
cadnano software to decide d_n_a_ oragami nanorobots which
can sense biological cues and exert specific effects
these nanorobots harness the remarkable features of d_n_a_ and may
advance the field of nanotechnology with a broad range of potential therapeutic
and industrial applications
