Mechanisms and kinetic assays of aminoacyl‐tRNA synthetases

FEBS Letters, EarlyView.
Accurate protein synthesis is crucial for life. The key players are aminoacyl‐tRNA synthetases (AARSs), which read the genetic code by pairing cognate amino acids and tRNAs. AARSs establish high amino acid selectivity by employing physicochemical limits in molecular recognition.

The Age-of-Information Distribution in Slotted ALOHA

IEEE Access
Age-of-Information (AoI) is a new performance metric for critical networked cyber-physical systems (CPS), where performance depends on how quickly fresh data is received in update packets.

A Neutrosophic Description Logic [PDF]

, 2008
Description Logics (DLs) are appropriate, widely used, logics for managing structured knowledge. They allow reasoning about individuals and concepts, i.e. set of individuals with common properties.

The epithelial barrier theory proposes a comprehensive explanation for the origins of allergic and other chronic noncommunicable diseases

FEBS Letters, EarlyView.
Exposure to common noxious agents (1), including allergens, pollutants, and micro‐nanoplastics, can cause epithelial barrier damage (2) in our body's protective linings. This may trigger an immune response to our microbiome (3). The epithelial barrier theory explains how this process can lead to chronic noncommunicable diseases (4) affecting organs ...

The question of meaning—a momentous issue for qualitative research

International Journal of Qualitative Studies on Health & Well-Being, 2019
In this article, we identify some worrying problems in the contemporary practice of qualitative research, such as the confusion regarding content and meaning in content analysis, the frequent use of standardized methods that avoids philosophy, as well as

Quark Description of Hadronic Phases [PDF]

, 1999
We extend our proposal that major universality classes of hadronic matter can be understood, and in favorable cases calculated, directly in the microscopic quark variables, to allow for splitting between strange and light quark masses.

ERBIN limits epithelial cell plasticity via suppression of TGF‐β signaling

FEBS Letters, EarlyView.
In breast and lung cancer patients, low ERBIN expression correlates with poor clinical outcomes. Here, we show that ERBIN inhibits TGF‐β‐induced epithelial‐to‐mesenchymal transition in NMuMG breast and A549 lung adenocarcinoma cell lines. ERBIN suppresses TGF‐β/SMAD signaling and reduces TGF‐β‐induced ERK phosphorylation.

The skull bones of the Iguana iguana

Bioscience Journal, 2016
The iguanas (Iguana iguana) are animals that can reach up 110 cm. The crest of spines that is located at the its back long characterizes these animals. They live from Mexico to Central Brazil, in the Amazon, Cerrado, and Caatinga, they live in trees and

Thermostable neutral metalloprotease from Geobacillus sp. EA1 does not share thermolysin's preference for substrates with leucine at the P1′ position

FEBS Letters, EarlyView.
Knowing how proteases recognise preferred substrates facilitates matching proteases to applications. The S1′ pocket of protease EA1 directs cleavage to the N‐terminal side of hydrophobic residues, particularly leucine. The S1′ pocket of thermolysin differs from EA's at only one position (leucine in place of phenylalanine), which decreases cleavage ...
