Ends and means in conflict [PDF]

open access: yes, 1987
journal articleA great danger of our time is our intense preoccupation with the ends we seek, so much so that we have overlooked the effect, usually and perhaps always the determinative effect, that our choice of means will have made upon the nature of ...

Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

open access: yesFEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

School Assessment in an inclusive education system – do we measure what we value or do we value what we can measure? [PDF]

open access: yes
This section will explain why we have focused on school-level assessment of inclusion. We will discuss different approaches to school assessment and how they can support inclusive practice in the light of diverse understandings of inclusion across ...

From mice to humans—divergent strategies for intestinal homeostasis and regeneration

open access: yesFEBS Letters, EarlyView.
Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

PARK(ing) time–How park deficiency affects the biological clock in a Drosophila model of Parkinson's disease

open access: yesFEBS Letters, EarlyView.
Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Monotonicity Results for Arithmetic Means of Concave and Convex Functions [PDF]

open access: yes, 2006
By majorization approaches, some known results on monotonicity of the arithmetic means of convex and concave functions are proved and generalized once ...

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis

open access: yesFEBS Letters, EarlyView.
Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Effect analysis of payload variation on energy consumption of a hydrogen powered light urban train [PDF]

open access: yes, 2019
In this study a light hybrid rail train hydrogen powered is considered and the influence of the payload factor variation on traction energy consumption is investigated.

Three phosphatase families form a community: The phosphohydrolases that act upon inositol pyrophosphates

open access: yesFEBS Letters, EarlyView.
Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Trade-Offs in Means Tested Pension Design [PDF]

open access: yes
Inclusion of means testing into age pension programs allows governments to better direct benefits to those most in need and to control funding costs by providing flexibility to control the participation rate (extensive margin) and the benefit level ...
