摘要:
The present invention relates to native cell wall compositions characterized by a relatively intact wall structure and uses of the compositions as micro-encapsulation agents. In a preferred embodiment this invention relates to native cell wall compositions derived from oat or barley flour wherein the native cell wall composition is composed primarily of beta-glucan.

The invention provides compositions and methods for increasing the levels of an autoantigen-specific IgM antibody in a mammal and, thus, decreasing the levels of a circulating autoantigen in a mammal. Using these autoantigen-specific IgM anti-bodies, the invention provides compositions and methods for ameliorating an autoimmune disease in a mammal. In one aspect, the invention provides compositions and methods for increasing the levels of an antigen-specific IgG antibody in a mammal and, thus, decreasing the levels of a circulating antigen in a mammal. Using these antigen-specific IgG antibodies, the invention provides compositions and methods for ameliorating a disease or condition in a mammal, e.g., a cancer or a foreign antigen, such as a pathogen.
摘要:
A gamma ray detector for determining the position of gamma ray interactions has at least one module (1). Each module has a converter (2) for converting gamma rays (3) to charged particles (4), a scintillator (5) for emitting light in response to charged particles produced by the converter, a photodectector (6) to determine when light has been emitted from the scintillator, a two-coordinate position detector (7) for determining the X and Y coordinates of charged particles interacting with the position detector, and a signal device (8) for signaling the presence of emitted light in the photodetector and for activating the position detector.
摘要:
The present invention relates to light guides (1) capable of encoding the transverse and longitudinal coordinates of light emission induced by the interaction of photons in an array of a plurality of the light guides. Each light guide has at least two discrete crystal segments (4) adjacently disposed along a common longitudinal axis of the light guide (1). Between adjacent segments is a boundary layer (7) having less light transmission than the light transmission of the crystal segments (4). A light absorbing mask (8) increases light adsorption in a segment (4). Photons enter the light guide (1) and cause the emission of scintillation light which is delivered in different and resolvable quantities to light sensing devices. The differences in quantity of delivered light is caused by successive decreases in light transmission to light transmitting end (5) caused at least in part by the boundary layers (7). The differences in quantity of light establish the segment from which the light emission took place.
摘要:
The present disclosure provides methods and compositions that find use in facilitating a diagnosis of inflammatory liver disease in a subject. The methods and compositions generally involve detection of eotaxin-3 (E3) levels, either alone or with levels of eotaxin-1 (E1), and optionally, with levels of CCL22 and, further optionally, with levels of IL15. These levels can be used to facilitate a diagnosis of a liver disease of at least one of autoimmune hepatitis (AIH), primary biliary cirrhosis (PBC), and primary sclerosing cholangitis (PSC), and/or to facilitate a differential diagnosis between AIH, PBC, and PSC. The methods and compositions of the present disclosure also find use in facilitating treatment decisions for a subject.
摘要:
Described herein is insulin, an insulin-like growth factor, parathyroid hormone, a fragment of parathyroid hormone, or a parathyroid hormone related protein that includes at least one bone targeting moiety, wherein the bone targeting moiety is covalently bonded to the peptide. Also described herein are the methods of making these compositions that prevent or treat conditions associated with bone loss and preventing bone fractures, and/or the inability to initiate de novo bone turnover and stimulate bone fracture repair.
摘要:
A method for preparing polyols from fatty acid substrates such as free fatty acids, alkyl esters of fatty acids, mono-glycerides, diglycerides, and triglycerides. The method comprises the steps of (a) epoxidizing an unsaturated fatty acid substrate and (b) hydroxylating the epoxidized fatty acid substrate with at least one diol to produce a polyol or a blend of polyols. The method may be varied to produce polyols with desired functionality, molecular weights, or viscosity.
