  • Publication number: 20250128189
    Abstract: The present disclosure relates to the detection of analytes in high volumetric flow applications. Particular embodiments relate to the use of fluorescence polarization/anisotropy based for detection of analytes in a flow cell. In one testing format, an analyte of interest is probed with reagents containing fluorescent labeled recognition elements. When present in a sample or portion of a sample, thee labeled analyte produces a shift in fluorescence polarization/anisotropy/intensity/lifetime as the output signal following the binding of the recognition elements to the analytes.

  • Patent number: 12256649
    Abstract: A superconductor tape and method for manufacturing, measuring, monitoring, and controlling same are disclosed. Embodiments are directed to a superconductor tape which includes a superconductor film overlying a buffer layer which overlies a substrate. In one embodiment, the superconductor film is defined as having a c-axis lattice constant higher than 11.74 Angstroms. In another embodiment, the superconductor film comprises BaMO3, where M=Zr, Sn, Ta, Nb, Hf, or Ce, and which has a (101) peak of BaMO3 elongated along an axis that is between 60° to 90° from an axis of the (001) peaks of the superconductor film. These and other embodiments achieve well-aligned nanocolumnar defects and thus a high lift factor, which can result in superior critical current performance of the tape in, for example, high magnetic fields.

  • Patent number: 12208287
    Abstract: The present invention addresses IBD from the standpoint of mucosal stem cells cloned from defined regions of the gastrointestinal tract. In the case of pediatric Crohn's disease, for example, isolation of those stem cells according to the methods of the present invention reveals a pattern of inflammatory gene expression in stem cells from the terminal ileum and colon that is epigenetically maintained despite months of continuous cultivation in the absence of immune or stromal cells, or of intestinal microbes. Superimposed on this distributed inflammatory phenotype is a differentiation defect that profoundly and specifically alters the mucosal barrier properties of the terminal ileum. The co-existence of diseased and normal stem cells within the same endoscopic biopsies of Crohn's disease patients implicates an epigenetically enforced heterogeneity among mucosal stem cells in the dynamics of this condition.

  • Patent number: 12208159
    Abstract: Provided herein are fluorinated compounds having chemical structures: (I) where n is 0 or greater, or (II) where m and n are 0 or greater, or an amino acid, a soluble polymer, an oligo(ethylene glycol), a poly(ethylene glycol), or a carbohydrate each fluorinated with perfluorocarbons having the chemical structure (III) where n is 0 or greater. These fluorinated compounds are utilized in contact lenses to impart lipid-resistant, protein-resistant and biofouling-resistant properties, thus reducing discomfort and infection caused by contact lens wear without changing its transmission characteristics. Also provided is an ophthalmic drug delivery system comprising at least one of the compounds described above embedded in the contact lens and a kit to incorporate the ophthalmic into a contact lens. Methods for incorporating these compounds onto a contact lens without affecting transparency and for use in treating an ophthalmologic-associated condition are provided.

  • Patent number: 12201416
    Abstract: A soleus contraction measurement system includes a sensor configured to measure rotational movement when positioned on a user's foot with an X-axis oriented laterally across the user's foot, a Y-axis oriented parallel to the user's foot, a Z-axis orthogonal to the X-axis and the Y-axis, and a positive X-axis rotational movement corresponding to an increasing ankle angle, and a memory storing computer-executable instructions for controlling a processor to: measure an X-axis rotational movement, identify a positive X-axis rotational movement as a plantarflexion and a negative X-axis rotational movement as an ankle dorsiflexion, deem the plantarflexion a performed soleus contraction when the plantarflexion is immediately followed by the ankle dorsiflexion for two consecutive cycles of plantarflexion and ankle dorsiflexion, and cause performance information regarding the performed soleus contractions to be communicated.

  • Publication number: 20250018009
    Abstract: Loss of cardiomyocytes underlies most causes of heart failure, and normal repair processes are inadequate to deal with extensive myocardial damage. The inventors have identified mutations of the N-terminus of serum respose factor (SRF)'s MADS box, termed STEMINs, that block cardiac differentiation, but also powerfully activate the stem cell marker genes Nanog and Octomer 4, as well as cyclins, which promotes adult myocyte replication. SRF Stemin mutations are not cardiac-specific, and also propel mammalian fibroblasts into a proliferative state. Thus, STEMINs may be useful for regeneration of all tissue and organ types, by activating partial pluripotency programs and enhacing repair by increased cell replication. Following withdrawal of STEMINs, the cells then return to normal cell identity.

  • Patent number: 12117380
    Abstract: Milling with ultraviolet excitation (MUVE) realizes high-throughput multiplex imaging of large three-dimensional samples. The instrumentation may comprise a UV-source attachment, precision stage attachment, and/or a blade assembly, and the instrumentation may overcome several constraints inherent to current state-of-the-art three-dimensional microscopy. MUVE offers throughput that is orders of magnitude faster than other technology by collecting a two-dimensional array of pixels simultaneously. The proposed instrumentation also utilizes serial ablation and provides the opportunity for true whole-organ imaging at microscopic resolution.
