A detector for optical analysis of a biochip determines the focal position of
a plurality of analytes on the biochip using one or more registration markers
on the biochip, wherein the analytes and the registration marker are
illuminated by different light sources. Therefore, contemplated configurations
will significantly reduce overall focusing time and automate proper
positioning of the biochip, while allowing to determine a focal position
without photobleaching or other undesirable effects on optically labile
compounds. Thus, automated analyses can be performed without manual user
intervention.
A drug eluting stent has a frame with at least one frame opening, and the
frame is covered with an outer continuous layer and/or an inner continuous
layer. The outer and/or inner layers further include a layer opening that at
least partially overlaps with the frame opening to form a continuous opening
having a size that allows endothelialization when the stent is implanted into
a blood vessel.
An automated matrix removal module is configurable to automatically withdraw
a portion of sample containing an interferent. The module is further
configurable to mix the portion of sample with a precipitating reagent
selected to react with the interferent to fonn a precipitant and then filter
mixture of sample and precipitant reagent through a filter. Finally, the
module is further configurable to flush the precipitant from the filter.
The cervical collar has three principal pieces: a back panel, a main collar
body, and a chin piece. The chin piece is permanently attached to the main
collar body and is only attached at its ends to the main collar body so that
the center portion of the chin piece can adjust to chin configuration. The
back panel engages behind the neck and is tightened with respect to the main
collar body to properly support the patient's head and protect the cervical
spine. The chin piece adjusts to the patient's chin configuration because it
is sufficiently flexible and only supported away from the chin area. Each of
the pieces has a foam cushioning layer.
Non-Embryonic Totipotent Blastomer-Like Stem Cells and Methods Therefor
Non-embryonic blastomere-like totipotent stem cells are disclosed. Most
preferably, such cells are obtained from various tissues of postnatal mammals
(e.g., using tissue biopsied from the mammal), are smaller than 1 flm, have
normal karyotype, and do not spontaneously differentiate in serum-free medium
without differentiation inhibitors. These non-embryonic blastomere-like
totipotent stem cells typically express CD66e, CEA-CAM-l and telomerase, but
do not typically express CDlO, SSEA-l, SSEA-3, and SSEA-4. Such blastomere-like
totipotent cells can be differentiated into ectodermal, mesodermal, or
endodermal tissues, including placental tissues and germ cells. Moreover, when
implanted into a mammal, such cells will not be teratogenic.
A parallel inducible cell-based kinase screen (PICKS) includes a plurality
ofcells that express a kinase gene under the control of an inducer and a
reporter gene, wherein the cells are derived from a single cell line, and
wherein the reporter gene generates a signal in response to catalytic activity
or inhibition of the expressed kinases. Particularly preferred systems include
cells expressing kinases from a single kinase signaling pathway, kinases from
a kinase family, and/or kinases from various different kinase signaling
pathways. Consequently, contemplated systems provide a platform for screening
for novel kinase inhibitors, inhibition specificity of particular kinase
inhibitors, and for analysis of inter-pathway and/or intra-pathway inhibition
of a kinase inhibitor.
An enzyme is inhibited by presenting the enzyme with a boron containing
structure having a tetrahedral boron atom covalently bound to four ligands.
Particularly preferred enzymes include prostaglandin endoperoxide synthase
(COX-1 and COX-2), and particularly preferred structures include a ligand that
confers at least 80-fold selectivity of COX-2 inhibition over COX-1 inhibition.
Consequently, further methods are directed towards induction of apoptosis in a
cell and methods of reducing pain.
Monocyclic L-Nucleosides, Analogs, and Uses Thereof
Novel monocyclic L-Nucleoside compounds have the general formula __. Embodiments of these compounds are contemplated to be useful in treating a wide variety of diseases including infections, infestations, neoplasms, and autoimmune diseases. Viewed in terms of mechanism, embodiments of the novel compounds show immunomodulatory activity, and are expected to be useful in modulating the cytokine pattern, including modulation of Th1 and Th2 response.
Configurations and Methods for Assisted Condensation
A condensation enhancer has a carrier to which carbonaceous nanostructured material is coupled such that a compound in gas phase contacting the enhancer condenses at a temperature that is higher than a condensation temperature of the compound on the condensation enhancer without the nanostructured material.
Compositions and Methods of Remediation Devices with Nanostructured Sorbent
Contemplated remediation devices include a substantially completely hydrophobic, non-porous, and carbonaceous, and most preferably nanostructured material enclosed in a retaining structure. In further preferred aspects, the material inside the retaining structure adsorbs a contaminant from a medium located outside the retaining structure. Especially preferred nanostructured materials comprise graphene, while preferred contaminants include optionally substituted hydrocarbons, organic solvents, and acids.
Binding and In Situ Destruction of Chemical Agents and Other Contaminants
A graphene-containing composition is employed to bind a contaminant, which is then destroyed in situ using microwave irradiation. In preferred aspects of the inventive subject matter, the microwave irradiation has a frequency and energy sufficient to cause electron emission from the graphene.
Volatile organic compounds are removed from a liquid and destroyed using a device in which an air stripper having alternating phases of hydrophilic and hydrophobic packing materials promotes transition of the VOC from the liquid phase into the gas phase, and wherein the is oxidized VOC in the gas phase on a hydrophobic carbon nanostructure that further comprises a catalytically active metal.
