摘要:
Neisseria meningitidis PorA constructs are provided which have one or more disrupted variable regions created by insertion of entire conserved regions or conserved region amino acids. The highly immunogenic variable regions of PorA are responsible for eliciting strain-specific immune responses that are not broadly protective, so disruption of the variable regions directs the immune response against conserved region epitopes to effectively immunize against a broader spectrum of N. meningitidis strains. Also provided are encoding nucleic acids, genetic constructs, host cells expressing the PorA constructs and compositions, kits and methods for detection and treatment of Neisseria meningitidis infections.

The present invention relates to compounds that selectively inhibit influenza A virus group (1) sialidases and are therefore potential anti-influenza agents.
摘要:
The invention provides a method of determining whether or not an individual has a predisposition to migraine including the step of determining whether an isolated nucleic acid obtained from the individual comprises a nucleotide sequence corresponding to at least a fragment of a dopamine β-hydroxylase (DBH) gene promoter, wherein the presence of a -1021C → T single nucleotide polymorphism (SNP) in said nucleotide sequence indicates whether or not said individual has an increased predisposition to migraine compared to an individual without the polymorphism. DBH -1021C/C homozygotes are particularly susceptible to migraine. The -1021T allele may exert a protective effect. The method is particularly suited to detection of a predisposition to migraine with aura in females. The invention also provides a diagnostic kit for detecting a -1021C→ T SNP associated with migraine. The method and kit may facilitate selection of individuals for migraine therapy which targets the dopaminergic system.
摘要:
Various compounds obtained from plants of the Barringtonia species which are derived from Barringtoside A and Barringtoside C as precursor compounds which especially have an arabinopyranosyl substituent at the 21 position which may optionally be further substituted with benzoyl, dibenzoyl, methyl butanoyl, methyl butyryl or tigloyl at the 3 or 4 positions. Alternatively at the 21 position there is provided tigloyl, benzoyl or dibenzoyl substituents.
摘要:
A method of determining whether an individual has a predisposition to migraine is provided, which method includes the step of isolating a nucleic acid that has a guanine to adenine polymorphism at nucleotide (2014) of a human estrogen receptor and/or a nucleic acid that has a (306) base pair insertion in intron (7) of a human progesterone receptor gene. The presence of either polymorphism is indicative of an increased predisposition to migraine. Furthermore, the presence of both the human estrogen receptor polymorphism and the human progesterone receptor gene polymorphism indicates a three-fold greater predisposition to migraine. Also provided are kits for use with these methods, the kits comprising primers and, optionally, a restriction endonuclease such as Btg 1, for molecular detection of a genetic a predisposition to migraine.

Genes and encoded proteins that are differentially expressed in cells and tissues of individuals suffering from multiple sclerosis compared to cells and tissues of non-sufferers are provided. Examples of these genes include Serum Transferrin; Ribonuclease pancreatic precursor; Eucaryotic translation elongation factor 1, alpha 1; Guanine nucleotide binding protein; Glutathione peroxidase 1; SLC10A1; Calpain subunit 1; Inositol 1,4,5 triphosphate 3 kinaseB; Peripheral myelin Protein 22; Mal (T cell differentiation Protein); CRYAB Crystallin, alpha B; Betaine-Homocysteine methyl transferase; ADP-ribosylation factor 5; Glutathione S-transferase; Phosphomannomutase1; Tubulin beta 5; Ubiquitin A-52 residue ribosomal protein factor product 1; SOD1 Superoxide dismutase 1; CST3 Cystatin C protease inhibitor; Small nuclear ribonucleoprotein polypeptide N; and Solute carrier 25. Genes of the invention may, at least in some cases, carry mutations or other sequence variations that affect gene expression and contribute to multiple sclerosis pathophysiology. These genes may be of diagnostic value in predicting a predisposition to multiple sclerosis, confirming clinical diagnosis of multiple sclerosis and in the discovery of compounds for use in treating multiple sclerosis.

The present invention relates to novel thioglycosides of D-galactofuranose that have an antimicrobial action, methods for their synthesis, pharmaceutical compositions containing them and methods for the treatment of patients suffering microbial infection.
摘要:
The present invention relates to a method for culturing and propagating a stem cell and/or progenitor cell and populations thereof. The method includes the step of selecting and transferring adherent cells from one surface to another for propagation. The method may be used with isolated adult human tissue. The propagated cells may be transplanted into a recipient as stem cells, progenitor cells and/or differentiated cells that may be genetically modified.
摘要:
The present invention relates to an isolated domain of G3BP-2 that mediates binding between G3BP-2 and other proteins, and nucleic acids encoding same. The invention also relates to a method for diagnosing, treating and preventing breast cancer including the step of using a nucleic acid and/or encoded polypeptide for G3BP-2, or fragment thereof, to detect, treat or prevent breast cancer in a mammal, preferably human. In one particular form, the invention relates to an antigen presenting cell, preferably a dendritic cell, that is capable of presenting G3BP-2 or fragments thereof. The invention also relates to lymphocytes, in particular cytotoxic T-lymphocytes, that are G3BP-2 antigen specific.
