Detection of Staphylococcus aureus Enterotoxin A (SEA) Using Dot-ELISA in Milk Samples

Journal of Medical Microbiology and Infectious Diseases, 2020
Introduction: Staphylococcus aureus enterotoxin A (SEA) is one of the most common causes of staphylococcal food poisoning. Due to the simplicity and no requirement for laboratory apparatuses, dot-ELISA is a choice method for detecting Staphylococcal ...

Dot-ELISA for the detection of IgM and IgG antibodies to Schistosoma mansoni worm and egg antigens, associated with egg excretion by patients DOT-ELISA para a detecção de anticorpos IgG e IgM para antígenos de ovos e vermes de Schistosoma mansoni, em associação com excreção de ovos por pacientes

Revista do Instituto de Medicina Tropical de São Paulo, 1995
Human schistosomiasis, caused by Schistosoma mansoni, is highly prevalent in Brazil and usually diagnosed by time consuming stool analysis. Serological tests are of limited use in this disease, mainly for epidemiological studies, showing no ...

Generating Unconventional Spin‐Orbit Torques With Patterned Phase Gradients in Tungsten Thin Films

Advanced Materials, EarlyView.
ABSTRACT A key aim in spintronics is to achieve current‐induced magnetization switching via spin‐orbit torques without external magnetic fields. For this, the focus of recent work has been on introducing controlled lateral gradients across ferromagnet/heavy‐metal devices, giving variations in thickness, composition, or interface quality.

Three highly sensitive monoclonal antibody-based serological assays for the detection of tomato mottle mosaic virus

Phytopathology Research, 2021
In recent years, tomato mottle mosaic virus (ToMMV) has become one of the most important viral pathogens affecting solanaceous crop production in Yunnan, Hainan, and Shandong provinces of China, often causing huge yield reductions. To provide farmers and

Bacteria‐Trained, MnO2‐Armored Dendritic Cells for Immunotherapy

Advanced Materials, EarlyView.
MnO2‐armored, bacteria‐trained dendritic cells undergo tumor‐responsive mechanical and immunological transformation. The nanocoating masks immune ligands and maintains a mechanically stiff, quiescent state during circulation, while the tumor microenvironment removes the armor and restores cellular deformability and immune accessibility.

GaSex Nanoparticles Modulate Neutrophil Function and Mitigate NET‐Driven Osteogenic Impairment in Osteomyelitis Therapy

Advanced Materials, EarlyView.
Neutrophil extracellular traps (NETs) emerge as a critical repair‐limiting factor in osteomyelitis, driving osteoblast mitochondrial dysfunction and excessive PINK1/Parkin‐mediated mitophagy. Gallium–selenium nanoparticles (GaSex) scavenge reactive oxygen species, redirect neutrophils from NETosis toward bactericidal phagocytosis, eliminate methicillin‐

EVALUATION OF NANO-GRAPHENE BASED SANDWICH AND DOT-ELISA AS PROMISING TECHNIQUES FOR DIAGNOSIS OF HUMAN INTESTINAL GIARDIASIS [PDF]

Journal of the Egyptian Society of Parasitology, 2019
Giardia intestinalis nowadays is recognized as the most common parasitological cause of diarrhea, with 280 million infections per year. Microscopic examination of faecal samples has the advantage of low cost and the ability to simultaneously identify ...

A Retinal Matrix Stiffening Model Reveals FAK‐Dependent Mechanotransduction in Pericytes Underlies Vascular Destabilization

Advanced Materials, EarlyView.
In this study, we show that retinal matrix stiffness is increased in diabetic mice. Using engineered human vascular models with controlled matrix stiffness, we demonstrate that stiffening activates focal adhesion kinase (FAK) signaling in pericytes, suppresses Notch signaling, and disrupts vascular morphology.

Silk Fibroin Nanofiber–Immobilized Horseradish Peroxidase Enables Continuous Preparation of Injectable Hydrogels With Negligible Residual Enzyme for Drug Delivery

Advanced Materials Technologies, EarlyView.
Overcoming the immunogenicity challenges of enzyme‐mediated crosslinking, a flow‐through reactor utilizing SFNF‐HRP enables the continuous production of injectable hydrogels. This continuous platform ensures homogeneous crosslinking while minimizing residual HRP in the resulting hydrogels.
