Both species richness and growth forms affect nutrient removal in constructed wetlands: A mesocosm experiment

Yumei Luo, Quan Chen, Fan Liu et al. · 2023 · Frontiers in Ecology and Evolution

Introduction Plant richness is thought to improve the function of constructed wetlands (CWs), but most CWs are planted with monocultures, with only a few employed polycultures, which have drawn contradictory conclusions. We suppose functional diversity is the key to better performance of plant communities and hypothesize that CWs planted with diverse growth forms are superior in plant growth and nutrient removal. Methods In this study, six emergent plant species categorized into slender type ( Schoenoplectus tabernaemontani, Typha orientalis ), fan type ( Iris sibirica, Acorus calamus ) and la

Effects of Acyclovir and IVIG on Behavioral Outcomes after HSV1 CNS Infection

Chandran Ramakrishna, Mari S. Golub, Abby J. Chiang et al. · 2017 · Behavioural Neurology

Herpes simplex virus 1 (HSV) encephalitis (HSE) has serious neurological complications, involving behavioral and cognitive impairments that cause significant morbidity and a reduced quality of life. We showed that HSE results from dysregulated central nervous system (CNS) inflammatory responses. We hypothesized that CNS inflammation is casually involved in behavioral abnormalities after HSE and that treatment with ACV and pooled human immunoglobulin (IVIG), an immunomodulatory drug, would improve outcomes compared to mice treated with phosphate buffered saline (PBS) or ACV alone.

Long‐term passive heat acclimation enhances maximal oxygen consumption via haematological and cardiac adaptation in endurance runners

Elliott J. Jenkins, Joseph A. Killick, Owain Zerilli et al. · 2025 · The Journal of Physiology

Abstract Long‐term heat acclimation has been shown to elevate haemoglobin mass (Hb mass ) and enhance maximal oxygen consumption (). To date, however, all evidence derives from exercise‐induced heat stress, making it unclear whether passive strategies, which allow athletes to maintain training intensities, can produce similar adaptations. Moreover, while heat‐induced increases in are often attributed to haematological changes, adaptation of other convective components of oxygen transport may underpin these improvements. To investigate whether 5 weeks of hot‐water immersion (HWI) would enhance
