The present invention provides for a system and method to detect low levels of the anthrax protective antigen (PA) exotoxin in biological fluids, wherein the system uses a metal-enhanced fluorescence (MEF)-PA assay in combination with microwave-accelerated PA protein surface absorption. Microwave irradiation rapidly accelerates PA deposition onto the surface adjacent to deposited metallic particles and significantly speeding up the MEF-PA assay and resulting in a total assay run time of less than 40 min with an analytical sensitivity of less than 1 pg/ml PA.

The invention relates to compositions and methods useful for enhancing hair growth and promoting skin regeneration. Particularly, the invention provides topical compositions including trimebutine, salts, or active metabolites thereof, for enhancing or inducing hair growth and promoting skin regeneration. Compositions comprising trimebutine or a pharmaceutically acceptable salt or active metabolite thereof and their use in the method of promoting hair growth or skin regeneration. Preferably trimebutine is trimebutine maleate or N-desmethyl trimebutine. Compositions are preferably in a form for topical administration, such as a gel.

The present invention relates to compositions and methods for modulating coagulation through modulating the level or activity of ENPP4.

The present invention provides for methods of epigenetic analysis. In some cases, the methods may include obtaining a sample comprising a nucleic acid sequence. In some cases, the nucleic acid sequence may comprise one or more epigenetic marks. The methods may include performing a sequencing. The methods may include distinguishing a hydroxymethylated base from a methylated base.

Tau protein has a causative role in Alzheimer's disease and multiple other neurodegenerative disorders exhibiting tau histopathology collectively termed tauopathies. The primary function of tau protein is to facilitate assembly and maintenance of microtubules in neuronal axons. In the disease process tau protein becomes modified, loses its affinity to microtubules and accumulates in the cell body where it forms aggregates. The large neurofibrillary tangles formed from tau protein assembled into filaments were thought to be the pathological structure of tau. However, more recent work indicates that smaller, soluble oligomeric forms of tau are best associated with neuron loss and memory impairment. Here, novel compositions of tau oligomers and novel mechanisms for tau oligomer nucleation, extension and termination are taught. Methods for producing and purifying these structures for the development of small molecule and immunotherapeutics as well as antibodies for biomarkers of neurodegenerative diseases are taught.

An animal model for motor neuron dysfunction in disease, e.g., amyotrophic lateral sclerosis (ALS), comprising a genetically modified non-human animal that comprises a genetically modified DR6 allele and exhibits normal phenotypes at birth and for a few weeks or months after birth. However, as the non-human animal ages, it develops motor neuron dysfunction that presents as one or more ALS-like symptoms, which may progress rapidly after onset. Methods of identifying candidate agents that may be used to prevent, delay or treat ALS are also provided.

The present disclosure provides methods and materials for screening a compound or monitoring a subjects response to a compound or dosing regimen for treating a PGRN-associated disorder. Methods and materials for identifying and treating a subject having a PGRN-associated disorder are also provided.

The present invention includes a composition and a method of modulating an immune response with a composition that comprises an anti-BAFF receptor antibody or binding fragment thereof that is bound or conjugated to an siRNA, and shRNA, or both, that targets a BAFF receptor mRNA.

The present invention relates to methods for identifying candidate therapeutics for a disease caused by a viral envelope protein. In particular, the method can include contacting a test envelope protein with the candidate and determining its activity.
