Synchronous Detection Method of Medicaments Influencing ARR in the Detection Process of Renin Activity by Liquid Chromatography-Tandem Mass Spectrometry
20220390472 · 2022-12-08 ·

The present invention provides a synchronous detection method of medicaments influencing ARR in the detecting process of renin activity by liquid chromatography-tandem mass spectrometry. The method achieves the qualitative screening of medicaments influencing ARR values while detecting plasma renin activity by liquid chromatography-tandem mass spectrometry; moreover, the method can be used to assist to analyze and judge ARR as negative, positive, false negative or false positive. The detecting method achieves effective extraction of angiotensin I and 43 hypertension therapeutics synchronously through protein precipitation to samples, and enables to perform synchronous detection of a plurality of indices including angiotensin I and 43 hypertension therapeutics on the extracted sample by liquid chromatography-tandem mass spectrometry technology of high throughput, high specificity and high sensitivity. Moreover, the detection method utilizes the MRM mass spectrum parameters for preliminary screening of the medicaments, and rechecks the medicaments according to the retention time thereof. The ARR detection value is combined with the medicament screening result for co-analysis, which effectively distinguishes the false positive or false negative result of the detection while avoiding the patient's withdrawal of medicament for treatment, thereby improving the detection accuracy of the actual primary aldosteronism, and facilitating clinical promotion and application.

Quantitative hormone and chemical analyte test result systems and methods
11519909 · 2022-12-06 · ·

Systems, methods, and apparatus are disclosed for determining quantitative hormone and chemical analyte results from qualitative test results. An image is taken of an ovulation test device. The image is analyzed to identify a color intensity ratio (T/C ratio) between a color density of a test-line to a color density of a control-line. Additionally, a quantitative substance level may be determined using the T/C ratio, by identifying the type of test device and referencing a data structure that relates quantitative substance levels to T/C ratios for the identified type of test device.

Genetically-mutated bacterial strain for detecting estrogenic compound and method for detecting estrogenic compound using the same

The present invention relates to a genetically mutated bacteria strain for detecting an estrogenic compound and a method for detecting an estrogenic compound by using the same. More specifically, the present invention relates to a bacteria strain having an ability to detect an estrogenic compound, transformed by plasmid A comprising base sequences in which a gene for encoding a coactivator interacting with an estrogen receptor ligand binding domain (ER LBD) is conjugated to a gene for encoding λCI protein, and plasmid B in which a gene for encoding an estrogen receptor ligand binding domain (ER LBD) is conjugated to a gene for encoding αNTD protein, and a method for detecting an estrogenic compound by using same. The present invention can provide genetically mutated bacteria for detecting an estrogenic compound and a method for detecting an estrogenic compound by using same since the bacteria are based on estrogen receptor protein originated from the human body, and thus are environmentally friendly, and the detection of the bacteria can be performed in a very short time with low cost and labor by virtue of a relatively simple process.

Treatment of Hypercoagulopathy in Cushing's Syndrome by Administration of Glucocorticoid Receptor Modulators
20230097191 · 2023-03-30 · ·

Novel methods for preventing, reducing the risk of development of, and for treating hypercoagulopathy in Cushing's syndrome patients with elevated risk of developing hypercoagulopathy are disclosed. The methods are further useful to prevent, to reduce the risk of developing, and to treat deep vein thrombosis (DVT), pulmonary embolism (PE), and venous thromboembolism (VTE); and to treat inflammatory states.

The methods include: administering heteroaryl-ketone fused azadecalin glucocorticoid receptor modulator (HKGRM) to a Cushing's syndrome patient at risk of developing hypercoagulopathy, thereby treating hypercoagulopathy. Methods of preventing, reducing risk of developing, and of treating DVT, PR, or VTE in a Cushing's syndrome patient comprise administering a HKGRM to the patient. Methods of unmasking and subsequently reducing an inflammatory state comprise administering an effective amount of a HKGRM to a Cushing's syndrome patient, effective first to increase inflammatory symptoms and then to subsequently decrease said inflammatory symptoms in the patient.

System for evaluating urine for the presence or absence of pregnanediol glucuronide and other hormones and analytes
11573225 · 2023-02-07 · ·

Various aspects of the system and methods described herein rely upon the operation of lateral flow assays specially configured to evaluate a bodily fluid for at least the presence or absence of pregnanediol glucuronide at a threshold selected from the range inclusive of 1 μg/mL-10 μg/mL. The results from the lateral flow assays are optionally interpreted in association with an application operating upon a mobile device or a system for the collection, interpretation and storage of results. The interpretations are useful in accordance with facilitating diagnoses and treatments associated with medical conditions related to the generated interpretations of the lateral flow assays.
