GLUCOSE DETECTING COMPLEX AND CONTACT LENS-TYPE SENSOR COMPRISING SAME FOR DETECTING GLUCOSE IN TEARS
20220248990 · 2022-08-11 ·

The present invention relates to a glucose detecting complex and a contact lens-type sensor comprising the same for detecting glucose in tears. The contact lens-type sensor for detecting glucose according to the present invention includes a complex in which glucose oxidase is coupled to cerium oxide nanoparticles. Such a configuration allows the visualization of changes in glucose concentrations and the quantitative measured of glucose in a simpler and more economical way. In addition, glucose concentrations can be monitored in real time through a non-invasive method by measuring the concentration of glucose in tears rather than in blood in comparison with the conventional blood glucose measurement method. Therefore, the present invention can be widely applied in the technical field for the early diagnosis and prevention of diabetes.

Rapid, low-sample-volume cholesterol and triglyceride assays

Reagents, assays, methods, kits, devices, and systems for rapid measurement of cholesterol and cholesterol sub-fractions from a blood sample are provided. Total cholesterol, low density lipoprotein cholesterol, and high density lipoprotein cholesterol can be measured in a single assay using kinetic measurements, under conditions in which cholesterol sub-species are converted to a detectable product at distinct rates. The detectable product is measured at different times after assay initiation. A lipase, cholesterol esterase, cholesterol oxidase and a peroxidase may be used together to produce colored product in amounts directly proportional to the quantity of cholesterol converted. Methods for calculating very-low density lipoprotein cholesterol levels by further including triglyceride measurements are disclosed. Assays may be performed in a single reaction mixture, allowing more accurate and precise cholesterol determinations, including ratios of cholesterol sub-fractions to total cholesterol, at less expense, than would be expected by performing several different assays in different reaction mixtures.

ELECTROANALYTICAL DETERMINATION OF LEUKOCYTE ESTERASE
20220017941 · 2022-01-20 ·

Disclosed are compositions and methods for detecting leukocyte esterase (LE) activity in a sample. The method can include contacting the sample with an assay sample comprising methyl pyruvate and alcohol oxidase to form a test sample, measuring H.sub.2O.sub.2 produced from contacting the sample and the assay sample in the test sample.

ANTIBODIES HAVING SPECIFICITY FOR THE ORF2I PROTEIN OF HEPATITIS E VIRUS AND USES THEREOF FOR DIAGNOSTIC PURPOSES

Hepatitis E virus (HEV) is annually responsible for 20 million infections with 3.4 million symptomatic cases and 70,000 deaths mainly occurring in less developed regions of the world. HEV is a non-enveloped virus containing a linear, single-stranded, positive-sense RNA genome that contains three open reading frames (ORFs), namely, ORF1, ORF2 and ORF3. ORF2 encodes the ORF2 viral capsid protein, which is involved in particle assembly, binding to host cells and eliciting neutralizing antibodies. Recently, 3 different forms of the ORF2 capsid protein were identified: infectious/intracellular ORF2 (ORF2i), glycosylated ORF2 (ORF2g), and cleaved ORF2 (ORF2c). The ORF2i protein, for which the precise sequence has been identified, is the form that is associated with infectious particles and thus antibodies having specificity for the ORF2i protein would be suitable for the diagnosis of HEV. The present fulfills this need by providing an antibody which binds to the ORF2i protein of hepatitis E virus and wherein said antibody does not bind to the ORF2g protein nor to the ORF2c of hepatitis E virus, and wherein the epitope of said antibody comprises at least one amino acid residue from amino acid residues 542 to 555 of SEQ ID NO: 1.

Bioreactor system

A three dimensional cell culture and bioreactor system is provided. The system comprises one or more cell culture chamber. Each cell culture chamber comprises an inlet port and an outlet port in fluid communication with the cell culture chamber. The cell culture chambers may be segregated or in fluid communication with one another. The systems may be used to conduct drug efficacy test, isolate certain cell types from a complex tissue sample of multiple cell types, allow for the ex vivo culturing of patient tissue samples to help guide the course of treatment, and conduct co-culture experiments.

METHOD FOR REMOVING DISSOLVED OXYGEN, USED IN AN ELECTROCHEMICAL BIOSENSOR THAT USES AN OXIDASE AS THE SENSOR ENZYME

The present invention relates to a method for removing oxygen, used in an electrochemical biosensor, and to a measurement system and a method for electrochemically determining a concentration of an analyte using said method.

BIOMARKERS, USES THEREOF FOR SELECTING IMMUNOTHERAPY INTERVENTION, AND IMMUNOTHERAPY METHODS

The instant disclosure provides biomarkers and methods for identifying subjects at risk of relapse or suitable for allogeneic hematopoietic stem cell transplant after adoptive immunotherapy to guide preemptive intervention, modified therapy, or the like. Exemplary biomarkers include pre-lymphodepletion levels of serum lactate dehydrogenase (LDH), pre-lymphodepletion levels of platelets, levels of MCP-1, levels of IL-17, and pre-treatment regimen disease pathology. Based on the determined risk-relapse profile, an at-risk subject may be treated with pre-emptive therapy, while a subject not at risk for relapse may not receive further treatment, or may receive an allogeneic hematopoietic stem cell transplant. Also provided are methods for treating a hematological malignancy, wherein certain embodiments of the methods comprise adoptive cell therapy in the context of BTK-inhibitor therapy and/or BTK-inhibitor therapy in the context of adoptive cell therapy. Also provided are methods for treating follicular lymphoma (FL).
