Tracer Applications of Noble Gas Radionuclides in the Geosciences

open access: yes, 2013
The noble gas radionuclides, including 81Kr (half-life = 229,000 yr), 85Kr (11 yr), and 39Ar (269 yr), possess nearly ideal chemical and physical properties for studies of earth and environmental processes.

Investigations Into the Human Metabolism of Trestolone (7α‐Methyl‐19‐Nortestosterone)

open access: yesDrug Testing and Analysis, EarlyView.
As the known metabolites of 7α‐methyl‐19‐nortestosterone (MENT), M1 and M2, suffer from chromatographic issues under routine doping control conditions, the human metabolism of MENT was reinvestigated. From the numerous new metabolites detected, especially, M5 and M10 were identified as the most promising candidates to be implemented into routine ...

100 years of monitoring in the Swiss National Park reveals overall decreasing rock glacier velocities

open access: yesCommunications Earth & Environment
The rock glaciers of the Swiss National Park were the first in the world where in-situ measurements of surface displacement were undertaken, starting with the pioneering work of Chaix in 1918.

Heterozygous Med13l mice recapitulate a developmental growth delay and craniofacial anomalies seen in MED13L syndrome

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Gene transcription is crucial for embryo and postnatal development and is regulated by the Mediator complex. Mediator is comprised of four submodules, including the kinase submodule (CKM). The CKM consists of MED13, MED12, CDK8, and CCNC.

Preservation biases in the fossil record distort species ecological niche and distribution models

open access: yesEcography, EarlyView.
Ecological niche models (ENMs) increasingly leverage the fossil record to understand species' environmental associations and predict their geographic distributions. However, fossils do not occur uniformly through time and space, which can compromise the robustness of ENMs and thus affect ecological conclusions. Here, we assessed how preservation biases

The Effect of Cold‐Temperature Storage on Lipid Stability, Physicochemical Characteristics and Texture Profiles of Plant‐Based Meat Analogues

open access: yesFood Chemistry International, EarlyView.
PBMA products were studied for their lipid stability, texture profiles and physicochemical properties under recommended refrigerated storage conditions. Lipid tests showed no indicators of lipid oxidation in the PBMA products after refrigerated storage; however, significant changes were observed in their textural and physicochemical properties ...
