Impact of Menstrual Cycle and Oral Contraceptives on Haematological and Inflammatory Biomarkers in Highly Trained Female Athletes

Drug Testing and Analysis, EarlyView.
In highly trained female athletes, haematological and inflammatory biomarkers were found to be independent of menstrual cycle phase, but oral contraceptive use increased transferrin, reticulocyte count and triglycerides and decreased interleukin‐6.

Toward a Cannabis Terroir: Untargeted Metabolomic Profiling of Authentic Samples Using Gas Chromatography–High‐Resolution Mass Spectrometry (GC‐HRMS) and Liquid Chromatography–High‐Resolution Tandem Mass Spectrometry (LC‐HRMS/MS)

Drug Testing and Analysis, EarlyView.
This study developed a comprehensive metabolomics workflow using GC‐HRMS and LC‐HRMS/MS and analyzed 35 CBD‐type cannabis flowers grown under varying conditions. Key discriminative compounds enabled classification by chemical phenotype and cultivation environment. The results showed that environmental factors influence chemical profiles, supporting the

Application of trajectory optimization techniques to upper atmosphere sampling flights using the F4-C Phantom aircraft [PDF]

Altitude potential of an off-the-shelf F4-C aircraft is examined. It is shown that the standard F4-C has a maximum altitude capability in the region from 85000 to 95000 ft, depending on the minimum dynamic pressures deemed acceptable for adequate flight ...

Permeability of granite from a shallow buried mountain pipe gallery tunnel under unloading confining pressure

Deep Underground Science and Engineering, EarlyView.
Triaxial compression tests under unloading confining pressure conditions were conducted to systematically analyze the permeability behavior of granite retrieved from the different classification surrounding rocks. Abstract The rock mass within mountain tunnels undergoes complex changes in permeability, strength, and deformation during tunneling ...

Powerful yet challenging: mechanistic niche models for predicting invasive species potential distribution under climate change

Ecography, EarlyView.
Risk assessments of invasive species present one of the most challenging applications of species distribution models (SDMs) due to the fundamental issues of distributional disequilibrium, niche changes, and truncation. Invasive species often occupy only a fraction of their potential environmental and geographic ranges, as their spatiotemporal dynamics ...
