Abstract: The present disclosure relates to a simple, fast, and low cost method for 3D microvascular imaging, termed “scatter labeled imaging of microvasculature in excised tissue” (SLIME). The method can include perfusing a contrast agent through vasculature of a tissue sample. The contrast agent can include colloids and a dispersant. After the contrast agent is perfused through the vasculature, the vasculature of the tissue sample can be treated with a molecule that cross links with at least a portion of the dispersant to form a sticky, non-Newtonian polymer that prevents leakage of the contrast agent out of the vasculature of the tissue sample. The tissue sample can then be immersed in a solution comprising a clearing agent and subsequently imaged.

Abstract: Methods of using a phosphoinositide 3-kinase p110-delta inhibitor to treat, delay the onset, or slow the progression of an autoimmune disease or disorder in a subject, without suppressing the subject's B cell responses to exogenous antigens or rendering the subject immunocompromised, as well as pharmaceutical compositions containing phosphoinositide 3-kinase p110-delta inhibitors in amounts suitable for convenient and accurate administration within these therapeutic methods.

Abstract: Compositions and methods for treating diabetic retinopathy or symptoms thereof are provided. The disclosed compositions and methods for treating diabetic retinopathy contravene the existing paradigm that Renin-Angiotensin System (RAS) blockade alone can treat, prevent, or reduce diabetic retinopathy. The disclosed compositions and methods include a combination or alternation of EET antagonists and ATI antagonists.

Abstract: The present invention relates to compositions and methods configured to deliver a stimulus (e.g., a therapeutic agent or a therapeutically beneficial signal) to a cell, tissue, organ, or organism. The stimulus is applied at least twice, and the first and second applications are separated by a rest period in which no further stimulus is actively applied. The rest period is of a duration (e.g., about 1-6 hours) sufficient to provoke an enhanced response to the second stimulus.

Abstract: An HDAC6-specific inhibitor (i.e., a compound of Formula I or II) is shown to reduce the pathogenesis associated with polycystic disease. Administration of an HDAC6-specific inhibitor attenuated many of the symptoms characteristic of polycystic liver disease including cyst formation, cyst growth and cholangiocyte proliferation. Treatment with a HDAC6-specific inhibitor also increased the amount of bile duct acetylated tubulin and ?-catenin phosphorylation and/or acetylation while reducing bile duct ?-catenin synthesis. These results demonstrate that HDAC6 is overexpressed in cystic cholangiocytes and that its pharmacological inhibition reduces cholangiocyte proliferation and cyst growth.

Abstract: Provided herein are analogs of unnatural nucleotides bearing predominantly hydrophobic nucleobase analogs that form unnatural base pairs during DNA polymerase-mediated replication of DNA or RNA polymerase-mediated transcription of RNA. In this manner, the unnatural nucleobases can be introduced in a site-specific way into oligonucleotides (single or double stranded DNA or RNA), where they can provide for site-specific cleavage, or can provide a reactive linker than can undergo functionalization with a cargo-bearing reagent by means of reaction with a primary amino group or by means of click chemistry with an alkyne group of the unnatural nucleobase linker.

Abstract: Provided herein are capillaries for use in an electrophoretic separations. The capillaries can comprise an elongated tubular wall defining a path for fluid flow from an inlet to a tapered outlet; and a decoupler junction positioned within the elongated tubular wall upstream of the tapered outlet. The decoupler junction can comprise a plurality of microchannels penetrating through the elongated tubular wall and an ion-permeable polymer coating the plurality of microchannels. Also provided are sheathless interfaces for coupling capillary electrophoresis (CE) with mass spectrometry that employ these capillaries.

Abstract: A method for accelerated segmented magnetic resonance (MR) image data acquisition includes using a plurality of RF pulses to excite one or more slices of an anatomical area of interest according to a predetermined slice acceleration factor. Next, a collapsed image comprising the slices is acquired using a consecutive segment acquisition process. Then, a parallel image reconstruction method is applied to the collapsed image to separate the collapsed image into a plurality of slice images.

Abstract: Methods are provided for tagging, characterizing and sorting double-stranded biomolecules while maintaining the integrity of the biomolecules.

Abstract: The use of microfluidic structures enables high throughput screening of protein crystallization. In one embodiment, an integrated combinatoric mixing chip allows for precise metering of reagents to rapidly create a large number of potential crystallization conditions, with possible crystal formations observed on chip. In an alternative embodiment, the microfluidic structures may be utilized to explore phase space conditions of a particular protein crystallizing agent combination, thereby identifying promising conditions and allowing for subsequent focused attempts to obtain crystal growth.
