Conserved binding mode but diverse interfaces of MreC‐PBP2 interactions

FEBS Letters, EarlyView.
The crystal structure of abMreC reveals a conserved two β‐barrel architecture and provides structural insights into its role within the bacterial elongasome. The abMreC–abPBP2 complex model identifies the molecular basis of MreC‐mediated PBP2 recognition, contributing to the regulation of peptidoglycan synthesis.

Remarks on some trechine ground beetle taxa from the Balkan peninsula (Coleoptera: Carabidae: Trechini) [PDF]

Archives of Biological Sciences, 2013
The purpose of this note is to offer some corrections and supplements to the paper of Lohaj et al. (2013), to prove the validity of recently described trechine genera in Serbia, and to comment on other erroneous facts presented in the analyzed ...

Microbiome‐blood–brain barrier interactions in aging — mechanisms and therapeutic potential

FEBS Letters, EarlyView.
Aging reshapes the gut microbiome (↓SCFA‐producing commensals; ↑pro‐inflammatory outputs), shifting circulating metabolites (↓SCFAs; ↑LPS, ↑TMAO, ↑PAA) that act at the BBB to increase nonspecific transcytosis, alter transport, and promote astrocyte reactivity, heightening brain vulnerability.

Experiences and Perceptions of Barriers to Health Services for Elderly in Rural Namibia

SAGE Open, 2015
We investigate barriers to accessing health facilities (e.g., transportation and cost of services) and health service delivery barriers (e.g., timeliness of services scheduling of appointments, language) that the literature suggest are operative ...

To revise or not to revise? This is the question

Annals of Operations Research
Abstract Buy and hold and periodical revisions are two competing investment strategies. Revising to the optimal one-period investment weights seemingly dominates the buy-and-hold strategy with random and uncontrolled investment weights determined by asset price changes.

Functional comparison of EncB and EncC cargo proteins in iron storage within the Myxococcus xanthus encapsulin

FEBS Letters, EarlyView.
Encapsulins are protein nanocompartments that play an important role in iron storage. In the Myxococcus xanthus encapsulin system, two cargo proteins called EncB and EncC contribute to iron mineralization. Here, we show that EncB and EncC generate iron‐containing minerals with distinct chemical compositions, suggesting that the composition of stored ...

Comparison and System Development of a Two-Coil and Three-Coil Inductive Link for Transcutaneous Power Transfer

IEEE Access
Implantable electronic devices are powerful tools to alleviate a range of medical conditions. To minimize the risk of infections and increase patient comfort, no wires should penetrate the skin.

The Shewanella oneidensis Fic enzyme SoFic targets the switch‐I region of EF‐Tu for AMPylation

FEBS Letters, EarlyView.
Fic enzymes mediate diverse post‐translational modifications across all domains of life, including AMPylation. Prokaryotic EF‐Tu can be AMPylated and deAMPylated by the conserved Fic enzyme SoFic. Structural and biochemical approaches were used to characterize the effect of AMPylation on EF‐Tu, SoFic's enzymatic activities, and the enzyme‐target ...

Artificial molecular machines and motors—Design and control of nanoscale motion

FEBS Letters, EarlyView.
Molecules are constantly moving because of thermal fluctuations, but random motion alone cannot be exploited to perform directional tasks. Artificial molecular machines use chemical, electrical, or light energy to bias this motion. Molecular shuttles, rotary motors, and supramolecular pumps illustrate how nanoscale movement can be controlled and ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research

FEBS Letters, EarlyView.
What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?
