Dendritic cell ICAM-1 strengthens synapses with CD8 T cells but is not required for their early differentiation
AbstractLymphocyte priming in lymph nodes (LNs) was postulated to depend on the formation of stable T cell receptor (TCR)-specific immune synapses (ISs) with antigen (Ag)-presenting dendritic cells (DCs). The high-affinity LFA-1 ligand ICAM-1 was implicated in different ISs studied in vitro. We dissect the in vivo roles of endogenous DC ICAM-1 in Ag-stimulated T cell proliferation

Discriminative Identification of SARS-CoV-2 Variants Based on Mass-Spectrometry Analysis
AbstractThe spread of SARS-CoV-2 variants of concern (VOCs) is of great importance since genetic changes may increase transmissibility, disease severity and reduce vaccine effectiveness. Moreover, these changes may lead to failure of diagnostic measures. Therefore, variant-specific diagnostic methods are essential. To date, genetic sequencing is the gold-standard method to

“Catch-up" therapy: combining antidotal treatment with dermal application of AHA following percutaneous VX poisoning in the domestic swine
AbstractLow-volatility organophosphorus chemical warfare agents (OP CWAs) are cholinesterase inhibitors which easily absorb into the skin, leading to the formation of a dermal depot from which they slowly enter the bloodstream. This leads to sustained cholinergic hyperstimulation, which if untreated may lead to death. However, current available countermeasures are not adequate

Phosphate Additives for Aging Inhibition of Impregnated Activated Carbon against Hazardous Gases
AbstractImpregnated activated carbons (IACs) used in air filtration gradually lose their efficacy for the chemisorption of noxious gases when exposed to humidity due to impregnated metal deactivation. In order to stabilize IACs against aging, and to prolong the filters’ shelf life, inorganic phosphate compounds (phosphoric acid and its three salts, NaHPO4, Na2HPO4, and Na3PO4)

Introducing Surface Roughness to a Stochastic and Rock’N’Roll Models to Describe Particle Resuspension in Turbulent Flows
AbstractResuspension phenomenon plays an important role in various environmental and industrial implications. Here we generalize a stochastic resuspension model (Fu et al., 2013) by incorporating a phenomenological adhesion model, which accounts for surface roughness (Rabinovich et al., 2000a) instead of its original interaction model that constructed to smooth surfaces to

Enhanced LC-ESI-MS/MS Sensitivity by Cationic Derivatization of Organophosphorus Acids
AbstractThe chemical derivatization to enhance the signal intensity and signal-to-noise (S/N) of several organophosphorus (OP) acids in liquid chromatography tandem mass spectrometry (LC-ESI-MS/MS) is illustrated. The OP class of compounds represents the environmental degradants of OP nerve agents and pesticides. N-(2-(bromomethyl)benzyl)-N,N-diethylethanaminium bromide (CAX-B)

Characterization of a novel psyllid-transmitted waikavirus in carrots
AbstractCarrots collected from the Western Negev region in Israel during the winter of 2019 showed disease symptoms of chlorosis, leaf curling, a loss of apical dominance, and multiple lateral roots that were not associated with known pathogens of the carrot yellows disease. Symptomatic carrots were studied for a possible involvement of plant viruses in disease manifestations

Is it foehn or sea breeze? Eulerian and Lagrangian analysis of the flow in the Jordan Valley
AbstractFor more than one century, the penetration of the Mediterranean Sea Breeze into the Jordan Valley has been studied. At times, the associated downslope westerlies in the Dead Sea area exhibit foehn characteristics, leading to a warming and drying upon arrival and therefore contradicting the typical characteristics of a sea breeze. In this paper, a particular summer day

Mind the Gap—A Perspective on Strategies for Protecting against Bacterial Infections during the Period from Infection to Eradication
AbstractThe emergence of antibiotic-resistant bacteria is a pressing public health concern, highlighting the need for alternative approaches to control bacterial infections. Promising approaches include the development of therapeutic vaccines and the utilization of innate immune activation techniques, which may prove useful in conjunction with antibiotics, as well as other

Label-free and specific detection of active Botulinum neurotoxin in 0.5 μL drops with the meta-nano-channel field-effect biosensor
AbstractBotulinum neurotoxins (BoNT) are the most poisonous and lethal substances known to humans, and as such there is a great need for fast, easy-to-use, and early BoNT detection technologies which are not available today. A biosensor based on field-effect transistor (FET) is a highly pursued sensing platform due to the inherent low-noise and amplification, low-cost, and the ultimate potential for the sensing of multiple
