Abstract:
A process for the separation of a gas from a gas stream using metal organic framework that is reversibly switchable between a first conformation that allows the first gas species to be captured in the metal organic framework, and a second conformation that allows the release of the captured first gas species, using light as the switching stimulus. The metal organic framework may comprise a metal and one or more ligands, in which the ligands contain an isomerisable group within the molecular chain that forms a link between adjacent metal atoms in the metal organic framework.
Abstract:
A method of optimising transcranial magnetic stimulation is described. An electrical signal is applied to a coil to generate one or more magnetic field pulses for transcranial magnetic stimulation of a target cortical region of a patient. The transcranial magnetic stimulation has stimulation parameters including orientation of the coil relative to the patient and intensity of the magnetic stimulation. At least the orientation of the coil relative to the patient is varied. At different orientations of the coil relative to the patient, neuron activation at the target cortical region is determined by monitoring changes in blood flow and/or blood oxygenation, e.g. using near infra-red spectroscopy. Based on information obtained during the monitoring, one or more optimal coil orientations for the transcranial magnetic stimulation are determined. Apparatus for carrying out the method is also described.
Abstract:
A method for the synthesis of an amino acid analogue or a salt, solvate, derivative, isomer or tautomer thereof comprising the steps of: (i) subjecting an amino acid containing a metathesisable group to metathesis with a compound containing a complementary metathesisable group of formula (I) or (II): (Formulae (I), (II)) wherein R1 and R2 are independently selected from H and substituted or unsubstituted C1 to C4 alkyl; each R3 is either absent or independently selected from a heteroatom, a substituted or unsubstituted C1 to C20 alkyl, and a substituted or unsubstituted C1 to C20 alkyl group interrupted by one or more heteroatoms; and each X is independently selected from H and an effector molecule; in the presence of a reagent to catalyse the metathesis to form a dicarba bridge between the amino acid containing a metathesisable group and the compound containing a complementary metathesisable group; and (ii) reducing the dicarba bridge to form a saturated dicarba bridge, wherein the reagent used to catalyse step (i) also catalyses step (ii).
Abstract:
The present disclosure provides methods for prevention and/or treatment of disease or illness in a patient by stimulating a patient's immune system through reactivation of the thymus. The patient's thymus is reactivated by interruption or ablation of sex steroid mediated signaling to the thymus, such as through the administration of LHRH agonists, LHRH antagonists, anti-LHRH receptor antibodies, anti-LHRH vaccines, anti-androgens, anti-estrogens, selective estrogen receptor modulators (SERMS), selective androgen receptor modulators (SARMS), aromatase inhibitors, or various combinations thereof. Non-limiting examples of illnesses or diseases that may be prevented or treated using the methods of the invention are those caused by viruses, bacteria, fungi, parasites, prions, cancers, allergens, asthma-inducing agents, or nullselfnull proteins and other antigens which cause autoimmune disease. In addition, optional gene therapy utilizing hematopoietic stem cells, lymphoid progenitor cells, and/or myeloid progenitor cells may be used in which the cells are administered to a patient in conjunction with treatment to reactivate the patient's thymus.

Abstract:
The present invention generally relates to neural stem cells, preferably foetal neural stem cells and their progeny thereof. The present invention provides methods of isolating, culturing and propagating neural stem cells preferably foetal neural stem cells and the development of neural stem cell lines and lineages. The present invention also relates to the use of neural stem cells and somatic cells (eg rat fetal fibroblasts) and cells expressing the telomerase catalytic component (TERT) for gene targeting and gene knockout experiments and for producing genetically modified animals. In a first aspect of the present invention there is provided a cellular composition comprising one or more cells having a property characteristic of a neural stem cell and wherein said neural stem cell is capable of long term culture. Preferably the cells have a property characteristic of a foetal neural stem cell. In another aspect of the present invention there is provided a method of producing an animal, said method comprising introducing a continuously growing donor cell nucleus from a continuously growing donor cell into an oocyte or embryo and allowing the resulting embryo to mature and to preferably develop to a foetus or an adult animal.
Abstract:
Sulfur cathodes which include cellulosic compositions containing a plurality of anionically functionalised cellulose nanofibres are described. The anionically functionalised cellulose nanofibres are highly charged and have a low aspect ratio. The sulfur cathodes possess low porosity, high surface smoothness and facilitate the transport of Li ions while hindering the transport of polysulfide anions. Batteries employing the sulfur cathodes have high gravimetric and volumetric density.

Abstract:
A method of screening candidate agents for their ability to modulate RAGE activity where such RAGE activity is induced by an active co-located GPCR, the method comprising the steps of: contacting a RAGE polypeptide with a GPCR polypeptide in the presence of a candidate agent where the GPCR polypeptide is constitutively active and/or is activated by addition of an agonist, partial agonist or allosteric modulator of that GPCR; and detecting whether the candidate agent is a modulator of RAGE ligand-independent activation of RAGE by activated co-located GPCR by detecting an effect indicative of modulation of RAGE activation by the presence of the candidate agent and/or by detecting RAGE-dependent signalling that is modulated by the presence of the candidate agent.
