Abstract: The present invention describes methods for quantifying and analyzing cell migration and drug screening. Such methods include a gel (or a hydrogel) comprising a polymer, and cells that forms an oxygen gradient within the gel by controlling the balance of the diffusion of oxygen through the top of the gel and by the consumption of oxygen uptake by the cells. The migration of the cells is determined while the cells are grown in the gel of the present invention.

Abstract: The present invention provides methods for manipulating epigenetic factors to treat pediatric or juvenile osteoporosis. Specifically, the present invention provides methods for the application of H3K27 demethylase inhibitors in pediatric or juvenile subjects with osteoporosis. Thus, the present invention provides methods of administration of the H3K27 demethylase inhibitor, GSK-J4, to pediatric or juvenile subjects to effectively inhibit primary and secondary pediatric osteoporosis, especially for long-term glucocorticoid treated patients (juvenile rheumatoid disorders, Crohn's disease, nephrotic syndrome, and Duchenne muscular dystrophy) and patients who have compromised mobility (cerebral palsy, Rett syndrome, Duchenne muscular dystrophy, spina bifida, and spinal muscular atrophy).
Abstract: The recently developed liquid-based Papanicolaou (Pap) smear allows not only cytologic evaluation but also collection of DNA for detection of HPV, the causative agent of cervical cancer. We tested these samples to detect somatic mutations present in rare tumor cells that might accumulate in the cervix once shed from endometrial and ovarian cancers. A panel of commonly mutated genes in endometrial and ovarian cancers was assembled and used to identify mutations in all 46 endometrial or cervical cancer tissue samples. We were able also able to identify the same mutations in the DNA from liquid Pap smears in 100% of endometrial cancers (24 of 24) and in 41% of ovarian cancers (9 of 22). We developed a sequence-based method to query mutations in 12 genes in a single liquid Pap smear without prior knowledge of the tumor's genotype.

The unit cell may include a ground plane layer comprising a first conductive material, and a phase change material layer operably coupled to the ground plane layer. The phase change material layer may include a phase change material configured to transition between an amorphous phase and a crystalline phase in response to a stimulus. The unit cell may further include a patterned element disposed adjacent to the phase change material layer and includes a second conductive material. In response to the phase change material transitioning from a first phase to a second phase, the metasurface unit cell may resonate to generate an electromagnetic signal having a defined wavelength. The first phase may be the amorphous phase or the crystalline phase and the second phase may be the other of the amorphous phase or the crystalline phase.

Abstract: A calibration platform may obtain measurements for aligning a real-world coordinate system and a display coordinate system. For example, the calibration platform may display, via an optical see-through head-mounted display (OST-HMD), a three-dimensional virtual object and receive, from a positional tracking device, information that relates to a current pose of a three-dimensional real-world object to be aligned with the three-dimensional virtual object. The calibration platform may record a three-dimensional position of a plurality of points on the three-dimensional real-world object based on the current pose of the three-dimensional real-world object, based on an indication that the plurality of points on the three-dimensional real-world object respectively corresponds with a plurality of points on the three-dimensional virtual object.

Abstract: An embodiment in accordance with the present invention includes a technology to continuously measure patient mobility automatically, using sensors that capture color and depth images along with algorithms that process the data and analyze the activities of the patients and providers to assess the highest level of mobility of the patient. An algorithm according to the present invention employs the following five steps: 1) analyze individual images to locate the regions containing every person in the scene (Person Localization), 2) for each person region, assign an identity to distinguish ‘patient’ vs. ‘not patient’ (Patient Identification), 3) determine the pose of the patient, with the help of contextual information (Patient Pose Classification and Context Detection), 4) measure the degree of motion of the patient (Motion Analysis), and 5) infer the highest mobility level of the patient using the combination of pose and motion characteristics (Mobility Classification).

Abstract: The present invention relates generally to the field of disorders of complement activation. More specifically, the present invention provides methods and compositions useful for diagnosing and treating atypical hemolytic uremic syndrome, antiphospholipid antibody syndrome and other disorders of the alternative pathway of complement activation. In one embodiment, a method comprises the steps of (a) incubating or contacting serum obtained from a patient suspected of having atypical hemolytic uremic syndrome (aHUS) with a glycosylphosphatidylinositol-anchored protein (GPI-AP) deficient cell line; and (b) performing a cell viability assay on the cells from step (a). In a specific embodiment, the method further comprises the step of diagnosing the patient as having aHUS based on a statistically significant increased difference of non-viable cells from the patient serum as compared to a control.

Abstract: Yes-associated protein (Yap), a downstream co-activator of the Hippo pathway, is highly expressed in the Treg cell subset, and is critical to maintain its suppressive activity. Originally discovered in Drosophila melanogaster, the Hippo signaling pathway is a major regulator of cellular growth and proliferation in mammals. Loss of Yap expression in Treg cells can lead to superior anti-tumor immune responses, and thus, Yap is an important immunotherapeutic target for cancer.
