Investigating the effects of membrane curvature inducing proteins on lipid droplets in Saccharomyces cerevisiaeNARA Subscribed
Background Reticulons (Rtn1p, Rtn2p) and Yop1p are proteins shaping the endoplasmic reticulum (ER) membrane curvature their function being to a large degree responsible for molding the membrane curvature in the tubular ER area. Lipid biosynthesis mainly takes place in the tubular parts of the ER and lipid droplets are formed in the tubular ER membrane. Nucleation constitutes the rate-limiting step in lipid droplet formation an...
Background and aims Early season weather fluctuations significantly impact corn ( Zea mays L.) seedling establishment and soil nitrogen availability. This study investigated the effect of flooding duration and temperature after planting on corn emergence, seedling biomass and soil inorganic nitrogen content supplemented by polymer-coated urea fertilizer. Methods A controlled environment experiment was conducted using a split-p...
Freshwater biodiversity in a rapidly changing Arctic: An expert horizon scan of key research questionsNARA Subscribed
Arctic freshwater biodiversity is rapidly changing due to climate warming, resource extraction, infrastructure development, and landscape transformation. To improve understanding, predict future responses, and inform policy formulation, research needs must be clearly identified. Using a horizon scan survey, Arctic freshwater experts from government, international agencies, and Indigenous Peoples identified 77 biodiversity rese...
Thermophilization: Concepts, Methods, and Implications of Changes in Community Composition due to Global WarmingNARA Subscribed
With global warming, many species will shift their geographic ranges coldward (i.e., towards higher latitudes and elevations) to remain within suitable thermal conditions. At the community level, these range shifts result in “thermophilization”—the increasing relative abundance of warm‐adapted (“thermophilic”) species and the concomitant decrease of cold‐adapted species over time. Quantifying rates of thermophilization provide...
Raman spectroscopic signatures of prostate cancer progression: correlation with gleason scoreNARA Subscribed
Prostate cancer (CaP) is a heterogeneous malignancy, and its grading via Gleason scoring is essential for prognosis and therapeutic decision‑making. However, traditional histopathological methods are limited in detecting subtle biochemical variations. This study applies Raman spectroscopy (RS) to formalin‑fixed paraffin‑embedded (FFPE) CaP tissues of varying Gleason scores to uncover biochemical signatures associated with tumo...
Stomatal Decoupling From Photosynthesis Under High Temperatures Is Consistent With Stomatal OptimisationNARA Subscribed
Stomatal pores on plant leaves regulate the gain of carbon through photosynthesis and the loss of water through transpiration. Through their responses to environmental conditions, stomata can constrain plant productivity and transpiration fluxes, exerting a strong control on climate feedbacks over land. Although mechanistic modelling of stomata remains a challenge, semi‐empirical and optimisation models have been successfully...
