Abstract: Methods for seeding live cells onto spatially defined regions of a substrate including multiple features (e.g., microwells or other microenvironments) utilize a stencil embodied in a hole-defining sacrificial film. A sacrificial film devoid of holes may be applied over features of a substrate, and a hole generating mechanism (e.g., hot needle or laser) aligned with features may be used to define holes in the film. Alternatively, holes may be predefined in a sacrificial film to form a stencil, and the stencil may be assembled to the substrate with the holes registered with features thereof. Thereafter, cells are seeded through holes in the film. Seeded cells are subject to incubation, further processing, and/or performance of one or more assays, and the hole-defining sacrificial film (stencil) may be removed.

Abstract: A method of making an electron beam irradiated osteoinductive implant is provided. The method comprises exposing an osteoinductive implant containing demineralized bone matrix (DBM) fibers to electron beam radiation at a dose of from about 10 kilograys to 100 kilograys for a period of time. The electron beam irradiation reduces microorganisms in the osteoinductive implant, and the electron beam irradiated osteoinductive implant retains osteoinductive properties. Methods of implantation and an irradiated osteoinductive implant are also disclosed.

Abstract: The invention provides a method for identifying methicillin resistant Staphylococcus aureus (MRSA) in a bacterial sample comprising the steps: classifying bacteria in the sample as Staphylococcus aureus (SA) and determining the presence or absence of the phenol soluble modulin peptide or a variant thereof wherein the presence of the PSM-mec peptide or variant thereof indicates methicillin resistant Staphylococcus aureus. The variant is preferably the formylated version of the PSM-mec peptide having a mass to charge ratio of 2415 in a singly protonated state.
Abstract: A skin care composition is disclosed comprising at least one exopolysaccharide (EPS) originating from a microbial mat, the EPS being in a concentration of about 0.001% w/w to about 1.5% w/w of the composition. Uses and methods of use thereof. In specific embodiments, the EPSs are derived from microorganisms isolated from microbial mats found in French Polynesia. The composition is useful in reducing signs of skin aging and environmental damage by altering skin cell metabolism and improving hydration.
Abstract: Single dye fluorescent staining and the combination of differences in both intensity and spectral emission permit determination of the minimum concentration of an antibiotic needed to inactivate bacteria (Minimum Inhibitory Concentration (MIC)), thereby providing a means for rapid Antibiotic Susceptibility Testing (AST). This allows for a quick and easy means for clinicians to determine a suitable treatment regimen for patients suffering from bacterial infections and those that eventually lead to sepsis.

Abstract: The invention relates to a mass-spectrometric method to determine microbial resistances to antibiotics, in which the microbes are cultured in a medium comprising an antibiotic, and a mass spectrum of the microbes is acquired after they have been cultured. The method is characterized by the fact that any microbial growth taking place during the culture is mass-spectrometrically determined with the aid of a reference substance, which is added in a dosed amount and is co-measured in the mass spectrum, wherein a growth in microbes indicates the resistance to the antibiotic.

Abstract: Ear corn is picked from corn fields by ear corn harvesters and transported to a central shelling station associated with an ethanol manufacturing facility. Shelled corn from the central shelling station is processed into ethanol at the ethanol manufacturing facility, and corn cobs from the central shelling station are burned to provide process heat for the ethanol manufacturing process. Energy is conserved and costs are reduced during the picking and shelling of the ear corn and by the burning of cobs for process heat.
