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.

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.

The present disclosure is directed to methods reagents and kits for solid phase extraction, derivatization with crown ether containing derivatizing agents, and mass spectrometry of the derivatized analytes.

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.

The present invention concerns methods to identify RIPK1 modulators capable of modulating RIPK1 activity, RIPK1 interacting molecules that modulate RIPK1 activity and pharmaceutical compositions comprising RIPK1 modulators.

A multi-analyte sensor device is disclosed. The multi-analyte device is a handheld device that includes a replaceable sensor. In one embodiment, the replaceable sensor includes a plurality of electrodes coated with one or more different molecular imprinted polymer (MIP) coatings for measuring concentrations of target analytes. The replaceable sensor is configured to be attached or detached from the device one or more times.

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 darkness intensity ratio (T/C ratio) between a darkness value of a test-line to a darkness value 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.

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.

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.

The present disclosure provides methods of risk stratification for the development of lung cancer and/or lung cancer recurrence, methods of treatment of a human having lung cancer with therapeutic agents for preventing estrogen metabolite production, and methods of treating a human having a high risk of developing lung cancer with therapeutic agents for preventing estrogen metabolite production.
