Small protein B (SmpB) is an essential component of the highly conserved tmRNA-SmpB system that has the dual function of releasing stalled ribosomes from damaged messenger RNAs and targeting incompletely synthesized protein fragments for degradation. Nuclear magnetic resonance (NMR) analysis of SmpB from Aquifex aeolicus revealed an antiparallel beta-barrel structure, with three helices packed ...

The RoboCup Rescue Robot and Simulation competitions have been held since 2000. The experience gained during these competitions has increased the maturity level of the field, which allowed deploying robots after real disasters (e.g. Fukushima Daiichi nuclear disaster). This article provides an overview of these competitions and highlights the state of the art and the lessons

This paper addresses the newly named phenomenon of ‘rescue supervision’. The phenomenon itself is unfortunately not new. Not every candidate is blessed with adequate doctoral supervision. This paper looks at some of the reasons why supervision may not be adequate, only one of which is that the supervisor is incompetent. Whatever the reasons for the inadequacy of the supervision, it is desirable...

Throughout their life, bacteria need to sense and respond to environmental stress. Thus, such stress responses can require dramatic cellular reprogramming, both at the transcriptional as well as the translational level. This review focuses on the protein factors that interact with the bacterial translational apparatus to respond to and cope with different types of environmental stress. For exam...

The human motor neuron degenerative disease spinal muscular atrophy with respiratory distress type 1 (SMARD1) is caused by loss of function mutations of immunoglobulin mu-binding protein 2 (IGHMBP2), a protein of unknown function that contains DNA/RNA helicase and nucleic acid-binding domains. Reduced IGHMBP2 protein levels in neuromuscular degeneration (nmd) mice, the mouse model of SMARD1, le...

In Saccharomyces cerevisiae, splicing is critical for expression of ribosomal protein genes (RPGs), which are among the most highly expressed genes and are tightly regulated according to growth and environmental conditions. However, knowledge of the precise mechanisms by which RPG pre-mRNA splicing is regulated on a gene-by-gene basis is lacking. Here we show that Rpl22p has an extraribosomal r...

Objective: This study aimed to compare the efficacy of rescue blankets with conventional blankets in terms of preventing hypothermia in the pre-hospital setting. Methods: In this randomized clinical trial, patients older than 18 years old with Cold Discomfort Scale (CDS) > 2, and those who were transferred to the emergency department (ED) by emergency medical service entered the study. Patients...

SsrA RNA acts as a tRNA and mRNA to modify proteins whose synthesis on ribosomes has stalled. Such proteins are marked for degradation by addition of peptide tags to their C termini in a reaction mediated by SsrA RNA and SmpB, a specific SsrA-RNA binding protein. Evidence is presented here for the existence of a larger ribonucleoprotein complex that contains ribosomal protein S1, phosphoribosyl...
