Design and analysis strategies for robust microbiome ageing research

open access: yesFEBS Letters, EarlyView.
The gut microbiome changes with age and associates with age‐related morbidity and mortality, establishing it as a potential biomarker and intervention target for ageing. Realising this potential requires methodological rigour, yet distinguishing biological signals from methodological artefacts remains challenging across cohorts. This review provides an

HmBRI size-exclusion chromatography (SEC) elution profile and visual light absorbance spectra in different environments.

open access: yes, 2014
(A) SEC elution profile of HmBRI. Two distinct peaks are observed, that correspond supposedly to monomeric HmBRI (at 73.4 ml, peak ratio is ∼1.95) and oligomeric HmBRI (at 67.8 ml, peak ratio is ∼1.85).

A unifying concept for the dependence of whole-crop N:P ratio on biomass : theory and experiment [PDF]

open access: yes, 2008
Background and Aims: Numerous estimates have been made of the concentrations of N and P required for good growth of crop species but they have not been defined by any unifying model.

EDNRB‐dependent endothelin signaling reduces proliferation and promotes proneural‐to‐mesenchymal transition in gliomas

open access: yesMolecular Oncology, EarlyView.
Glioma cells mainly express the endothelin receptor EDNRB, while EDNRA is restricted to a perivascular tumor subpopulation. Endothelin signaling reduces glioma cell proliferation while promoting migration and a proneural‐to‐mesenchymal transition associated with poor prognosis. This pathway activates Ca2+, K+, ERK, and STAT3 signalings and is regulated

Longitudinal genome‐wide aneuploidy measurements in circulating cell‐free DNA to predict lack of benefit from pembrolizumab in patients with metastatic urothelial cancer

open access: yesMolecular Oncology, EarlyView.
Many patients with urothelial cancer do not benefit from treatment with pembrolizumab, while at risk of severe side effects. Changes in the levels of circulating tumor DNA early during treatment, measured by a simple and affordable assay that can be easily implemented in the clinic, can be used as a prognostic tool to identify these patients.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.

Performance based evaluation of chloride penetration resistance of high performance mortar with hollow microspheres developed for floating marine structures

open access: yesCase Studies in Construction Materials
Due to the lack of land space from increasing population, number of marine structure construction has increased recently. In order to construct sustainable marine structures, the durability performance of concrete used for the construction in marine ...
