Development of a dendrimer PAMAM‑based gold biochip for rapid and sensitive detection of endogenous IFN‑γ and anti‑IFN‑γ IgG in patients with hemophagocytic lymphohistiocytosis.

Hemophagocytic lymphohistiocytosis (HLH) is a rare but severe disease characterized by immune hyperactivation and cytokine storm. Given the high mortality rate of HLH, there is a need for more effective diagnostic tools and treatments. The present study developed a dendrimer‑based protein biochip for rapid, sensitive and simultaneous detection of serum interferon (IFN)‑γ and endogenous anti‑IFN‑γ antibody (Ab) in patients with HLH.

[Biological effects of root exudates from resistant and susceptible banana varieties on f. sp. and ].

Root exudates of banana resistant variety ('Nantianhuang') and susceptible variety ('Guijiao No. 6') to Fusarium wilt were collected by bathing root system to examine the biological effects of root exudates from banana varieties on f. sp.

[Effect of minimally invasive plate osteosynthesis through two approaches on bone metabolic activity and radial nerve injury in patients with humeral midshaft fracture].

Objective: To compare application of minimally invasive plate osteosynthesis (MIPO) through two approaches for patients with humeral midshaft fracture, and analyzes the effect on bone metabolic activity and radial nerve injury.

Methods: From April 2014 to May 2017, 76 patients with humeral midshaft fracture treated by MIPO were selected and randomly divided into group A (anterior approache group) and group B (lateral approach group) according to random number stable. In group A, there were 38 patients including 22 males and 16 females, aged from 18 to 74 years old with an average age of(48.

Circ_ANKIB1 stabilizes the regulation of miR-19b on SOCS3/STAT3 pathway to promote osteosarcoma cell growth and invasion.

Osteosarcoma is a highly malignant tumor. The molecular mechanism of its occurrence and development has not yet been clarified. Current studies have found that noncoding RNAs, such as circular RNAs (circRNAs) and microRNAs (miRNAs), play important regulatory roles in the progression of diseases.

A biochip-based combined immunoassay for detection of serological status of Borrelia burgdorferi in Lyme borreliosis.

Background: Dithiobis (succinimidyl undecanoate) modified gold surface biochip were used as a combined immunoassay platform for concurrently detecting immune responses to Borrelia burgdorferi (B. burgdorferi) sensu lato antigens, flagellin, outer surface protein C, variable major protein-like sequence proteins, and 3 VlsE protein IR peptides. The peptides represented intrinsic Borrelia genospecies: B.

Succinyl-β-cyclodextrin modified gold biochip improved seroimmunological detection sensitivity for Lyme disease.

Cyclodextrin (CD) is a kind of cyclic oligosaccharides, which forms host-guest interactions with hydrophobic molecules and is widely applied in capillary electrophoresis and pharmaceutical engineering. In this study, we established a succinyl-β-CD modified gold biochip for improvement of seroimmunological detection sensitivity of Lyme disease. We found that the CD modified biochip platform presented a stronger affinity property for VlsE protein in conjugation with >0.

Development of a novel protein biochip enabling validation of immunological assays and detection of serum IgG and IgM antibodies against Treponema pallidum pathogens in the patients with syphilis.

In this study, we developed a novel protein biochip methodology that was characterized by dithiobis (succinimidyl undecanoate) (DSU) and specialized for detection of serum IgG and IgM antibodies against Treponema pallidum pathogens in the patients with syphilis, respectively. The biochips were validated by a dimension of atomic force microscope (AFM). The visualized detection limit of IgG antibody on the biochip was 0.
