The ageing holobiont: crosstalk between telomere dynamics, oxidative stress and the gut microbiome

Biological Reviews, EarlyView.
ABSTRACT The gut tissue is at the frontline of early onset of ageing. It exhibits high cell turnover rates and rapid telomere shortening, which can have systemic effects on the developing or senescing organism. We conducted a literature review of studies on the crosstalk between telomere length dynamics, telomerase activity, oxidative stress, and gut ...

Dynamics of biotic resistance to plant invasions

Biological Reviews, EarlyView.
ABSTRACT Biotic resistance, the reduction in invasion success caused by native communities, plays an important role in the long‐term dynamics of biological invasions. A large body of empirical research on biotic resistance has accumulated since the last comprehensive review on the subject 20 years ago, enabling us to achieve a refined understanding of ...

Radiologic, Histologic and Scanning Electron Microscopic Characterization of the Peritoneal Reflection in Crohn's Disease

Clinical Anatomy, EarlyView.
ABSTRACT The peritoneal reflection bridges visceral and parietal peritoneum and lacks adjoining or underlying organs. As such it provides an opportunity to perform a focussed examination of the peritoneum in Crohn's disease. The aim of this study was to exploit this anatomical property and conduct a multilayered, focussed examination of the peritoneal ...

Inclusion Complexations of Levamisole and Cocaine With Molecular Baskets. Fluorescence Displacement Assay for Detection of Cocaine and Its Adulterant Levamisole in Aqueous Media

Chemistry – A European Journal, EarlyView.
Levamisole is a common adulterant found in street‐distributed cocaine. Molecular baskets have been shown to form stable inclusion complexes with both substances. While levamisole inserts its benzene into the basket's cavity, cocaine utilizes its bicyclic ring for encapsulation.

Single‐cell sequencing reveals potential novel insights into appendage‐patterning and joint‐development in a spider

Developmental Dynamics, EarlyView.
Abstract Background Jointed appendages represent one of the key innovations of arthropods, and thus understanding the development and evolution of these structures is important for the understanding of the evolutionary success of Arthropoda. In this paper, we analyze a cell cluster that was identified in a previous single‐cell sequencing (SCS ...

The β integrin modulates serotonin sensitivity via NPxY motifs to regulate egg laying and mechanosensation behaviors in Caenorhabditis elegans

Developmental Dynamics, EarlyView.
Abstract Background Integrin is an αβ heterodimeric receptor to the extracellular matrix; its binding to the matrix recruits focal adhesions to two NPxY motifs, the tyrosine phosphorylation sites in the cytoplasmic domain. Studies found that replacing tyrosines (Y) with phenylalanines (F) in the motif of β1 integrin displayed little developmental or ...
