Rhizoferrin may supply iron to the R. oryzae through an energy-dependent receptor-mediated pathway, but the exact mechanism of whether this siderophore releases iron extracellularly or is internalized before releasing iron is not known yet [32, 34]. Two more recently introduced iron chelators are Deferiprone (act as bidentate chelator) and ...
The inset shows a pair of pre-synaptic and post-synaptic spikes, and the spike pair is designed to implement STDP [20]. The paired-pulse facilitation (PPF) is a phenomenon wherein the post-synaptic response induced by the spike increases when the time interval of the two spikes is very close . PPF index can be defined as follows:

Emodin blocks the SARS coronavirus spike protein and angiotensin-converting enzyme 2 (ACE2) interaction. Emodin inhibits casein kinase-2 (CK2). Anti-inflammatory and anticancer effects. Emodin is a potent selective 11β-HSD1 inhibitor with the IC 50 of 186 and 86 nM for human and mouse 11β-HSD1, respectively. Emodin ameliorates metabolic ...
The fabrication of colorless and see-through dye-sensitized solar cells (DSCs) requires the photosensitizers to have little or no absorption in the visible light region of the solar spectrum. However, a trade-off between transparency and power conversion efficiency (PCE) has to be tackled, since most transparent DSCs are showing low PCE when compared to colorful …

RNA-based therapies, including RNA molecules as drugs and RNA-targeted small molecules, offer unique opportunities to expand the range of therapeutic targets. Various forms of RNAs may be used to selectively act on proteins, transcripts, and genes that cannot be targeted by conventional small molecules or proteins. Although development of RNA drugs faces …
It is thought that snow cover may reduce the rate of desiccation, protect plants from abrasion, and insulate them from low temperatures. Rare exceptions to the normal morphology are the specimens CAN 23127 and CAN 483451, with two staminate spikes, and CAN 483450, which has a subterminal spike with both staminate and pistillate flowers.
The angiotensin-converting enzyme (ACE)-related carboxypeptidase, ACE2, is a type I integral membrane protein of 805 amino acids that contains one HEXXH + E zinc-binding consensus sequence. ACE2 has been implicated in the regulation of heart function and also as a functional receptor for the coronavirus that causes the severe acute respiratory syndrome (SARS).

9. It may interest some readers to know that the corresponding author of this paper, and of another paper the same year cited previously (Payton et al., 1969a), Brian Payton, went on to become well known in certain circles as a cultural twin of the Monty Python brand of satire, as applied to physiology.His most well-known production is the film "Proprioceptive Receptor …
Du et al. showed how a potent COVID-19 antibody, BD-368-2, interacts with the SARS-CoV-2 spike trimer to neutralize the virus and effectively treat severely infected hamsters. They further demonstrated how BD-368-2 can be paired with additional antibodies to form a cocktail that prevents the evolution of viral escape mutants.
Understanding the long-term fate of widespread noncrystalline uranium (U) species is critical to improving our knowledge of U biogeochemistry and U-contaminated environments. We use naturally U-enriched lake sediments that have been deposited for thousands of years as an analogue for the progressive evolution of contaminated environments, in order to uncover if …
