The present invention relates, in general, to an immunogen and, in particular, to an immunogen for inducing antibodies that neutralize a wide spectrum of HIV primary isolates and / or to an immunogen that induces a T cell immune response. The invention also relates to a method of inducing anti-HIV antibodies, and / or to a method of inducing a T cell immune response, using such an immunogen. The invention further relates to nucleic acid sequences encoding the present immunogens.

Compositions are disclosed that induce broadly HIV therapeutic and vaccine inducing antibodies against diverse HIV clades and relate to the ability to identify HIV gp120-derived short peptide sequence immunogens and various therapeutic compositions made from the identified peptides which compose CCR5 binding sites. Also disclosed are methods of selecting peptide sequences that are likely candidates for drugs which will offer effective treatment in such areas as Alzheimer's disease, psoriasis, multiple sclerosis and other diseases associated with the human inflammatory cascade as well as related retroviruses such as HTLV-1, the cause of tropical spastic paraparesis.

Disclosed and claimed are: epitopic regions of Pneumococcal Surface Protein C or “PspC”, different clades of PspC, isolated and / or purified nucleic acid molecules such as DNA encoding a fragment or portion of PspC such as an epitopic region of PspC or at least one epitope of PspC, uses for such nucleic acid molecules, e.g., to detect the presence of PspC or of S. pneumoniae by detecting a nucleic acid molecule therefor in a sample such as by amplification and / or a polymerase chain reaction, vectors or plasmids which contain and / or express such nucleic acid molecles, e.g., in vitro or in vivo, immunological, immunogenic or vaccine compositions including at least one PspC and / or a portion thereof (such as at least one epitopic region of at least one PspC and / or at least one polypeptide encoding at least one epitope of at least one PspC), either alone or in further combination with at least one second pneumococcal antigen, such as at least one different PspC and / or a fragment thereof and / or at least one PspA and / or at least one epitopic region of at least one PspA and / or at least one polypeptide including at least one epitope of PspA. PspC or a fragment thereof, and thus a composition including PspC or a fragment thereof, can be administered by the same routes, and in approximately the same amounts, as PspA. Thus, the invention further provides methods for administering PspC or a fragment thereof, as well as uses of PspC or a fragment thereof to formulate such compositions.

A rapid diagnostic assay for influenza virus, particularly avian influenza and more particularly H5N1, is described. The assay is based on amplification of a significant portion of the hemagglutinin (HA) gene and sequencing of several loci within the HA gene, using techniques which can obtain real time sequence information from multiple sites of a target DNA, in particular pyrosequencing and bioluminescence regenerative cycle. The assay contemplates the use of information-rich subsequences within the HA gene, e.g., (1) a glycosylation sequon; (2) receptor binding site; and (3) HA1 / HA2 cleavage site. Other subsequences for sequencing include strain and clade markers, which vary among H5N1 strains.

Embodiments of the present invention provide a data flow processing method and device, the processing method includes: sampling the data flow in the network at the sampling moment to obtain the first data; according to the first data, determining the first characteristic of the first data vector; if according to the cluster set and the first eigenvector, it is determined that the data flow is not an abnormal flow, then perform cluster analysis on the first eigenvector according to the cluster set, obtain a new cluster set, and return to the executed The data flow in the network is sampled at the sampling moment; wherein, the number of clusters in the cluster cluster set is different from the number of clusters in the new cluster cluster set; the processing method of the data stream provided by the embodiment of the present invention And the device, since the clustering cluster set used to determine whether the data stream is an abnormal stream is updated in real time, and the number of clusters in the clustering cluster set is also changed in real time, the accuracy of judging the data stream can be improved.

The present invention relates to recombinant microorganisms comprising biosynthetic pathways and methods of using said recombinant microorganisms to produce various beneficial metabolites. In various aspects of the invention, the recombinant microorganisms may further comprise one or more modifications resulting in the reduction or elimination of 3 keto-acid (e.g., acetolactate and 2-aceto-2-hydroxybutyrate) and / or aldehyde-derived by-products. In various embodiments described herein, the recombinant microorganisms may be microorganisms of the Saccharomyces clade, Crabtree-negative yeast microorganisms, Crabtree-positive yeast microorganisms, post-WGD (whole genome duplication) yeast microorganisms, pre-WGD (whole genome duplication) yeast microorganisms, and non-fermenting yeast microorganisms.

An anti-HIV vaccine composition is disclosed. The vaccine comprises an combination of immunogenic peptide mixtures, which mixtures may be prepared in a single synthesis. The composition collectively represents the in vivo variability seen in immunogenic epitopes from highly variable regions of HIV. Immunization with the vaccine elicits broadly reactive immunity (CTL and T helper cell responses) against the divergent strains of HIV upon which it is based. The vaccine may be formulated to target regionally distinct variability based on an HIV clade predominant in a geographical region.
