Abstract: Methods for generating porous scaffolds may include tuning a porogen/crystallite's particle size to a desired range and mixing the crystallite particles with a polymer solution. The mixture is then cast to form films. The films are rolled and consolidated around another inner material to create a preform, which is then thermally drawn. The inner material and the porogen can be selectively removed to obtain porous constructs/fibers. The structures can be fuse-printed to produce complex tissue scaffolds with dimensions up to several centimeters and beyond.

Abstract: The compositions and methods provided herein are related, in part, to the discovery of cholic acid 7-sulfate as a treatment for diabetes. Selective transport of the microbial metabolite lithocholic acid (LCA) from the gut to the liver after bariatric surgery activates hepatic vitamin D receptor (VDR), thereby inducing expression of bile acid sulfotransferase SULT2A, which produces the antidiabetic molecule CA7S. Provided herein is a method for treating diabetes, obesity, or an inflammatory disease in a subject, the method comprises administering to a subject in need thereof a compound of Formula I-XV or Formula F-XV? or an agent that increases levels or activity or cholic acid 7-sulfate or upstream targets in a subject.

Also described herein are biomarker profiles, including a biomarker profile comprising two groups of Clostridial species, that is predictive of the likelihood of recurrent C. difficile infection and/or susceptibility to initial C. difficile infection.

Abstract: This disclosure relates to compositions including formulated sucralfate or other aluminum-crosslinked sulfated agents for delivery of agents to biological surfaces and/or the modulation of nutrient absorption through the intestinal lining as well as methods for the manufacture of and the use of these compositions for treating disorders including diabetes type II and clinical obesity that require a modulation of certain nutrients to the body.

Abstract: Extended field-of-view imaging is enabled by combined imaging with a kilovolt (“kV”) x-ray source and a megavolt (“MV”) x-ray source, in which at least one of the corresponding x-ray detectors is laterally offset from the target isocenter by an amount such that the x-ray detector does not have a view of the target isocenter. This scan geometry enables the reconstruction of non-truncated images without resorting to the more expensive solution of outfitting the imaging or radiotherapy system with enlarged x-ray detectors.

Abstract: A system and method is provided for controlling physiological-noise in functional magnetic resonance imaging using raw k-space data to extract physiological noise effects. The method can identify these effects when they are separable and directly reflects the artefactual effects on fMRI data, without the need for external monitoring or recording devices and to be compensated for via rigorous statistical analysis modeling of such noise sources. The physiological fluctuations may be treated as global perturbations presented around the origin point in a k-space 2D slice. Each k-space 2D slice may be acquired at a very short repetition time with an effective sampling rate to sample cardiac and respiratory rhythms through proper reordering and phase-unwarping techniques applied to the raw k-space data.
