The in vivo T cell response to persistent Ag contains a hyporesponsive phase following an initial expansion and subsequent partial deletion of the responding cells. The mechanism(s) responsible for this tolerance process is poorly understood. In this study, we describe a new paired transgenic model (TCR and Ag), which within 7-14 days produces 20-40 million hyporesponsive T cells. This state is...

Gold-coated silver wire was developed to alleviate the high cost of Au used in semiconductor packaging. Ball-bonding and stitch-bonding techniques were fabricate dummy packaging material, comprising 97.3 % Ag, 97.3% Au-Coated 99.99 %Au wires. The ball shear test (BST), pull (BPT), microstructural attributes ultrasonic bonding interfaces compared with initial properties, both before after highly...

The main focus of the current research is bio-nano-technologically produced nanoparticles (NPs) utilizing waste materials. There a need for developing advanced technology to reduce in an eco-friendly way. Therefore, presently discarded aqueous portion Prosopis cineraria pod was used after boiling, synthesize Ag and Ag–Cu NPs. FT-IR spectra illustrated presence phenyl propenoids flavonoids displ...

The endocannabinoid 2-arachidonoylglycerol (2-AG) is a lipid mediator involved in various physiological processes. In response to neural activity, 2-AG is synthesized post-synaptically, then activates pre-synaptic cannabinoid CB1 receptors (CB1Rs) in a retrograde manner, resulting in transient and long-lasting reduction of neurotransmitter release. The signalling competence of 2-AG is tightly r...

In this research, silver nanoparticles (Ag NPs) were prepared by a low-cost, rapid, simple and ecofriendly approach using Grape fruit extract as a novel natural reducing and stabilizing agent. The product was characterized by UV-visible spectroscopy, X-ray diffraction (XRD), Fourier transform infrared spectroscopy (FTIR), field emission scanning electron microscopy (FESEM), energy-dispersive X-...

Rapid enterovirus detection is important for decisions about antibiotic administration and length of hospital stay. The efficacy of rapid antigen detection-cell culture amplification (Ag-CCA) was evaluated with monoclonal antibodies (MAbs) 5-D8/1 (DAKO) and Pan-Enterovirus clone 2E11 (Chemicon) with 10 poliovirus, echovirus, and coxsackievirus type A and B stock isolates and College of American...

Recent research suggests that today's condoms are only 85% effective in preventing human immunodeficiency virus (HIV) and other sexually transmitted diseases. In response, there has been a push to develop more effective ways of decreasing the spread of the disease. The new nanotechnology-based condom holds the promise of being more potent than the first-generation products. The preliminary goal...
