Orthogonally redundant sensor systems and methods

A continuous glucose monitoring system may include a hand-held monitor, a transmitter, an insulin pump, and an orthogonally redundant glucose sensor, which may comprise an optical glucose sensor and a non-optical glucose sensor. The former may be a fiber optical sensor, including a competitive glucose binding affinity assay with a glucose analog and a fluorophore-labeled glucose receptor, which is interrogated by an optical interrogating system, e.g., a stacked planar integrated optical system. The non-optical sensor may be an electrochemical sensor having a plurality of electrodes distributed along the length thereof. Proximal portions of the optical and electrochemical sensors may be housed inside the transmitter and operationally coupled with instrumentation for, e.g., receiving signals from the sensors, converting to respective glucose values, and communicating the glucose values. The sensors' distal portions may be inserted into a user's body via a single delivery needle and may be co-located inside the user's body.

Multivalent glycan microarray platform
11231415 · 2022-01-25 · ·

The present invention includes a multivalent glycan microarray for detection of glycan-binding proteins. The multivalent glycan microarray allows a multivalent presentation of glycan on a microarray substrate, which can enhance binding of the glycan binding protein to the glycan microarray. The multivalent microarray includes a solid substrate having one or more branched polymers bonded to it via one or more silane-based linker reagents. The branched polymer in turn is bonded to a glycan, via one or more bifunctional linkers to form the multivalent glycan microarray. Nonspecific binding of glycan binding proteins to the multivalent glycan microarray can be reduced by using a blocking reagent coated on to the microarray substrate, which includes a polyethylene glycol surfactant attached to the solid substrate via a self-crosslinking azido-functionalized silane. Methods for making multivalent glycan microarrays and methods for using same to detect glycan-binding proteins are also disclosed.

Method, biomarker and diagnostic agent for detection of high-risk prostate cancer

[Problem] To provide a method for detecting high-risk prostate cancer, for the purpose of providing useful information, such as necessity of biopsy, to a test-positive patient in a PSA test. [Solution] The method for detecting high-risk prostate cancer according to the present invention comprises reacting a PSA contained in a sample composed of urine collected from a human body which is suspected to be suffering from prostate cancer with (1) a fucose α1.fwdarw.6 affinitive lectin which has a characteristic property that the lectin has affinity expressed by a binding constant of 1.0×10.sup.4 M.sup.−1 or more (at 25° C.) for an α1.fwdarw.6 fucose sugar chain No. 405. The fucose α1.fwdarw.6 affinitive lectin is preferably (2) a fucose α1.fwdarw.6 specific lectin which has a characteristic property that the lectin has a binding constant of 1.0×10.sup.4 M.sup.−1 or less (at 25° C.) for a sugar chain No. 003 that does not contain α1.fwdarw.6 fucose and a glycolipid-type sugar chain No. 909 that does not contain α1.fwdarw.6 fucose.

METHOD OF MEASURING COMPLEX CARBOHYDRATES

A transformative method to profile the glycome in individual cells by leveraging computational biology tools with lectin or similar profiling technologies.

Fucosylated α.sub.1-acid glycoprotein (fAGP) was found to be useful for the diagnosis of pancreatic cancer and malignant intraductal papillary mucinous neoplasm (IPMC), resulting in the finding of a new biomarker for pancreatic cancer or malignant intraductal papillary mucinous neoplasm (IPMC), in particular, a new biomarker useful for rapid diagnosis of malignant intraductal papillary mucinous neoplasm (IPMC) that increases the accuracy of malignant intraductal papillary mucinous neoplasm (IPMC) and aids conventional imaging diagnosis by making a suitable preoperative diagnosis of a benign neoplasm or a malignant neoplasm in intraductal papillary mucinous neoplasm (IPMN).

METHODS OF TREATING OR INHIBITING CARDIOVASCULAR DISEASES

Disclosed herein are methods and compositions for inhibiting, preventing, ameliorating, reducing, or treating cardiovascular diseases, for example, stroke, traumatic brain injury, cerebral amyloid angiopathy, atherosclerosis, myocardial infarction, and/or diseases associated with fibrin activity or dysfunction. These methods and compositions involve antibodies that can bind to Galectin-3 and inhibit, prevent, ameliorate, reduce, or treat the cardiovascular diseases in a patient by reducing inflammation and/or inhibiting oligomerization of proteins associated with pathology such as amyloid beta or fibrin.

Engineered microbe-targeting molecules and uses thereof

Described herein are engineered microbe-targeting or microbe-binding molecules, kits comprising the same and uses thereof. Some particular embodiments of the microbe-targeting or microbe-binding molecules comprise a carbohydrate recognition domain of mannose-binding lectin, or a fragment thereof, linked to a portion of a Fc region. In some embodiments, the microbe-targeting molecules or microbe-binding molecules can be conjugated to a substrate, e.g., a magnetic microbead, forming a microbe-targeting substrate (e.g., a microbe-targeting magnetic microbead). Such microbe-targeting molecules and/or substrates and the kits comprising the same can bind and/or capture of a microbe and/or microbial matter thereof, and can thus be used in various applications, e.g., diagnosis and/or treatment of an infection caused by microbes such as sepsis in a subject or any environmental surface. Microbe-targeting molecules and/or substrates can be regenerated after use by washing with a low pH buffer or buffer in which calcium is insoluble.
