The first natural aptamer discovered in biology probably was the lac operator, although that “aptamer” consisted of double-stranded DNA. However, the large number of DNA sites to which specific proteins bind does reflect our first principle: evolution can demand and get tight and specific binding...
A large Josephson diode effect has been reported at liquid-nitrogen temperatures in twisted flakes of Bi2Sr2CaCu2O8+δ. Sanat Ghosh ,Vilas Patil &Mandar M. Deshmukh Article|06 February 2024 High-quality nanocavities through multimodal confinement of hyperbolic polaritons in hexagonal boron nitride ...
Xylanolytic enzymes from glycoside hydrolase family 43 (GH43) are involved in the breakdown of hemicellulose, the second most abundant carbohydrate in plants. Here, we kinetically and mechanistically describe the non-reducing-end xylose-releasing exo-oli

The nitrogen fertiliser treatment was only manipulated at three of the five sites, and parameters related to the nitrogen treatment were tested by being crossed with site as fixed in the model for the relevant sites only. To select the best model, comparisons were carried out using AIC from ...
The cuvette was first cali- brated for oxygen and then flushed with nitrogen gas. Then, a known volume of C O2 was added to create an atmosphere of approximately 18O2 was injected 4% CO2 (high pCO2) within the chamber; to give an atmosphere of 18–21% O2 and the signals...
the tip of the leaflet closest to the stem from the second true leaf, using sanitized micro-dissecting scissors (re-sanitized for each sampling). Samples were individually collected in sealable plastic sleeves, sleeves were heat sealed, and immediately flash-frozen by submerging in liquid nitrogen....
In addition to their difference in size and SUN domain locations, these protein subfamilies are distinct in other interesting ways (Table2). The CCSD-type proteins have a basic isoelectric point, whereas the PM3-type proteins have an acidic one (Table2). In addition, the PM3 proteins have ...
nitrogen fixation, and carbon sequestration5,6,7,8. Microbial communities can be described in a number of ways—e.g., based on their abundance, diversity, and community composition—which are relevant facets of how these communities perform the resulting soil ecosystem functions9. Soil microbial ...
(to the limbal margin) were dissected under an operating microscope, embedded in optimal cutting temperature compound, and snap-frozen in liquid nitrogen. Corneas were stored at −80 °C until further use. For histology, rat and pig tissue were thawed, fixed in 4% paraformaldehyde solution...
