Simultaneous Detection of Prolactin and Growth Hormone Using a Dual-label Time-resolved Fluorescence Immunoassay.

Prolactin (PRL) and growth hormone (GH) are two important hormones secreted by the pituitary gland, and their abnormal levels are often related to disease status. This study aimed to establish a new dual-label time-resolved fluorescence immunoassay (TRFIA) to quantitatively measure PRL and GH levels in serum. A sandwich TRFIA was optimized and established: anti-PRL/GH antibodies immobilized on 96-well plates captured PRL/GH and then banded together with anti-PRL/GH paired antibodies labeled with europium(III) (Eu)/samarium(III) (Sm) chelates.

Determination of serum CA724 levels using fluorescence immunochromatography.

Background: Carbohydrate antigen 724 (CA724) is a sensitive and specific indicator for multiple malignant tumors. The aim of this study was to establish a Eu-time resolved fluorescence immunochromatography (Eu-TRFICO) method for quantitative detection of CA724 in serum.

Methods: Eu-TRFICO strips were optimized and assembled.

Determination of echinococcosis IgG antibodies using magnetic bead-based chemiluminescence immunoassay.

Echinococcosis is a kind of parasitic disease shared by humans and animals. The aim of this study was to establish a new detection method for echinococcosis screening using magnetic bead-based chemiluminescence immunoassay (CLIA). A magnetic bead-based CLIA to determine anti-echinococcosis IgG antibodies was optimized and established.

A New Method for Early Screening of Gastric Cancer (G17 and CA724 Dual-Labeled Time-Resolved Fluorescence Immunoassay).

Gastric carcinoma (GC) is one of the most common malignancies in the world with the great early screening challenges. The study is aimed at establishing a new detection method for early screening GC using time-resolved fluorescence immunoassay (TRFIA) via quantitative detection of gastrin-17 (G-17) and carbohydrate antigen 724 (CA724) in serum. Time-resolved analyzer measured the fluorescence intensity.

Determination of parvovirus antigen in the vaccine using time-resolved fluorescence immunoassay.

As a highly contagious and potentially fatal disease of dogs, canine parvovirus type 2 (CPV-2) usually causes severe myocarditis and gastroenteritis, while vaccine injection has greatly reduced the incidence of CPV-2 diseases. However, there is currently a lack of simple and effective method for quantitative detection of CPV-2 in vaccine. Therefore, this study aims to prepare an accurate method to determine the CPV-2 antigen (CPV-2-Ag) in vaccine.

Astragaloside IV inhibits excessive mesangial cell proliferation and renal fibrosis caused by diabetic nephropathy via modulation of the TGF-β1/Smad/miR-192 signaling pathway.

Astragaloside IV (ASI) exhibits a wide variety of pharmacological effects in cardiovascular diseases, hepatitis and kidney disease and due to this, ASI has recently become an attractive research target. The present study aimed to determine the effect of ASI on renal fibrosis and the mechanisms underlying its therapeutic effects in diabetic nephropathy (DN). , ASI was added to rat mesangial cells (RMCs) and cultured with a high level of glucose (HG) to observe the effects exhibited on proliferation and fibrosis-related mRNA and protein expression.

Determination of parvovirus antibodies in canine serum using magnetic bead-based chemiluminescence immunoassay.

Canine parvovirus type 2 (CPV-2), as a highly contagious and potentially fatal disease of dogs and many other carnivores, usually causes severe gastroenteritis and myocarditis. Therefore, it is very necessary and urgent to have an accurate method to determine the CPV-2 antibodies (CPV-2-Ab) in canine samples. Here, a magnetic bead-based chemiluminescence immunoassay was established and optimized to detect the concentration of CPV-2-Ab in serum.

Effects of Acupuncture on 1-chloro-2,4-dinitrochlorobenzene-induced Allergic Contact Dermatitis in Mice.

Allergic contact dermatitis (ACD) is a chronic inflammatory skin disease. Topical corticosteroids are the first-line therapy for ACD despite their significant adverse effects. Acupuncture has been widely used in the treatment of various skin diseases, but its underlying mechanism remains unrevealed.
