Evolution of lysine and arginine biosynthesis revealed by substrate specificity of lysine biosynthetic enzymes in Thermus thermophilus

The FEBS Journal, EarlyView.
Two enzymes from the Thermus thermophilus lysine biosynthetic pathway, LysZ and LysY, unexpectedly exhibit substrate promiscuity. They are able to recognize the LysW intermediates utilized by the ArgW‐mediated arginine route, even though the bacterium already possesses the canonical arginine biosynthetic pathway.

Zebrafish as a model for Catel–Manzke syndrome—identification and characterization of the zebrafish TGDS ortholog

The FEBS Journal, EarlyView.
Zebrafish Tgds, when expressed as a recombinant protein, catalyzes the dehydration of UDP‐D‐glucose, the initial step in the formation of 6‐deoxyhexoses. Corresponding Tgds mutations found in Catel–Manzke syndrome patients lead to reduced enzymatic activity and stability.

Parkinson's Disease and Salivary Issues: A Survey

Gerodontology, EarlyView.
ABSTRACT Background Salivary dysfunction, including xerostomia and drooling, is common in Parkinson's disease and further impairs oral health and quality of life, which are already compromised in this population. Their effective management demands deeper insight into the complexity of salivary dysfunction.

Prison Officers as Providers of Social Support: An Analysis of the Human Service Values and Power Dynamics Present in Prison Officers’ Accounts of Assisting Inmates

The Howard Journal of Crime and Justice, EarlyView.
ABSTRACT Previous research has shown that prison officers often provide practical and emotional assistance to inmates. However, this has generally been depicted as a discretionary, conflicted and unrewarded task, sometimes met with hostility from their peers.

A fast metaheuristic approach for the planar multiple obnoxious facility location problem

International Transactions in Operational Research, EarlyView.
Abstract The multiple obnoxious facility location problem is one of the most studied problems in the literature of the obnoxious facility location problems family. In this work, we propose an alternative algorithmic approach for this problem, based on an efficient metaheuristic procedure over a discretization of the plane based on Voronoi diagrams ...

Evaluation of drone system for thinning operations–a case study in Sweden

International Transactions in Operational Research, EarlyView.
Abstract Thinning operations in forestry typically involve a two‐machine system (TMS) with a harvester and a forwarder. Its productivity in different forest conditions is well documented. To date, drones have been used for data collection and surveillance but not as an alternative to a TMS.
