Platelets and the Cybernetic Regulation of Ischemic Inflammatory Responses through PNC Formation Regulated by Extracellular Nucleotide Metabolism and Signaling

open access: yesCells, 2022
Ischemic events are associated with severe inflammation and are here referred to as ischemic inflammatory response (IIR). Recent studies identified the formation of platelet–neutrophil complexes (PNC) as key players in IIR.

Simple estimation of incident HIV infection rates in notification cohorts based on window periods of algorithms for evaluation of line-immunoassay result patterns. [PDF]

open access: yesPLoS ONE, 2013
Tests for recent infections (TRIs) are important for HIV surveillance. We have shown that a patient's antibody pattern in a confirmatory line immunoassay (Inno-Lia) also yields information on time since infection. We have published algorithms which, with

CALIPSO (IIR-CALIOP) Retrievals of Cirrus Cloud Ice Particle Concentrations.

open access: yesAtmospheric Chemistry and Physics, 2018
A new satellite remote sensing method is described whereby the sensitivity of thermal infrared wave resonance absorption to small ice crystals is exploited to estimate cirrus cloud ice particle number concentration N, effective diameter De, and ice water

Sustainable plant nutrients generated from symbiotic waste treatment for safe application in food crop production

open access: yesEnvironmental Science and Sustainable Development
Adequate soil nutrients are necessary for plant growth and health. Nitrogen sources from synthetic ammonia production have a high energy requirement, with implications for global warming. Innovative ways of producing nitrogen, such as crop nutrients from

Sustainable recycling of butyl rubbers: an insight into the radiation processing [PDF]

open access: yesPolímeros
This investigation presents a deep examination on the behavior of radiation effects on pristine (IIR) and halogenated butyl (IIR-Cl, IIR-Br) rubbers. The retrieving these materials is appropriately achieved by the radiolysis fragmentation of main chains ...

Aging behaviors of the Al–Cu alloy via ultrasound-promoted thermal treatments

open access: yesJournal of Materials Research and Technology
Aging treatments have been widely utilized for enhancing the mechanical properties of many materials, such as Al–Cu alloys. In conventional aging treatments, there is a trade-off between the aging conditions (e.g., aging times and temperatures) and the ...
