Inherited immunodeficiencies associated with proximal and distal defects in T cell receptor signaling and co-signaling

open access: yesBiomedical Journal, 2022
T lymphocytes are central cells of adaptive immunity. Activation of T lymphocytes by the antigen receptor of T cells (TCR) and co-stimulatory molecules involve specific signaling components and cascades.

Stimulation of TRPV1 by green laser light [PDF]

open access: yes, 2012
Low-level laser irradiation of visible light had been introduced as a medical treatment already more than 40 years ago, but its medical application still remains controversial.

Active listening

open access: yesHearing Research, 2020
AbstractThis paper introduces active listening, as a unified framework for synthesising and recognising speech. The notion ofactive listeninginherits from active inference, which considers perception and action under one universal imperative: to maximise the evidence for our (generative) models of the world.

Scalable carbon dioxide electroreduction coupled to carbonylation chemistry

open access: yesNature Communications, 2017
Electroreduction of CO2 to CO is a potential valorisation pathway of carbon dioxide for fine chemicals production. Here, the authors show a user-friendly device that couples CO2 electroreduction with carbonylation chemistry for up to gram scale synthesis

Myosin IIa Promotes Antibody Responses by Regulating B Cell Activation, Acquisition of Antigen, and Proliferation

open access: yesCell Reports, 2018
Summary: B cell responses are regulated by antigen acquisition, processing, and presentation to helper T cells. These functions are thought to depend on contractile activity of non-muscle myosin IIa.

Cooperative redox activation for carbon dioxide conversion

open access: yesNature Communications, 2016
While CO2 can be converted to CO for further reactivity, typically this involves the generation of large amounts of waste. Here the authors report the conversion of CO2to CO, with the siloxane by-product being further used in a carbonylative Hiyama ...

Determination of activation volumes of reversal in perpendicular media [PDF]

open access: yes, 2003
We discuss a method for the determination of activation volumes of reversal in perpendicular media. This method does not require correction for the self-demagnetizing field normally associated with these media.

ACE2 ACTIVATION PROMOTES ANTITHROMBOTIC ACTIVITY

open access: yesThe FASEB Journal, 2009
Hyperactivity of the axis ACE/AngII/AT1R of the renin‐angiotensin system is associated with occurrence of acute thrombotic event. Recently a novel concept of a counterrugulatory axis, ACE2/Ang‐(1‐7)/Mas, has emerged. We hypothesized that ACE2 would be protective against thrombosis.
