Light and temperature drive the distribution of mesophotic benthic communities in the Central Indian Ocean

open access: yesDiversity and Distributions, Volume 29, Issue 12, Page 1578-1593, December 2023., 2023
Abstract Aim Research on mesophotic coral ecosystems (MCEs) has increased exponentially in recent decades, and the significance of this ecosystem has been recognised both in terms of biodiversity and distribution. However, this research has mostly focussed on corals and is globally sporadic, with the Indian Ocean remaining largely unexplored and ...

Cooling streams with riparian trees: Thermal regime depends on total solar radiation penetrating the canopy

open access: yesAustral Ecology, Volume 48, Issue 6, Page 1064-1073, September 2023., 2023
Our note examines the spectral composition of solar radiation penetrating tree canopies as it affects the energy balance and therefore water temperature of shaded streams. Because tree leaves transmit near‐infrared (NIR) radiation (comprising about 50% of insolation) much more efficiently than photosynthetically available radiation (PAR; visible light),

Prognostic impact of kallikrein‐related peptidase transcript levels in prostate cancer

open access: yesInternational Journal of Cancer, Volume 153, Issue 4, Page 867-881, 15 August 2023., 2023
What's new? Several kallikrein‐related peptidases (KLKs) are associated with prostate cancer, most notably KLK3, also called prostate‐specific antigen. The relationship between most human KLKs and prostate cancer, however, remains unclear. In our study, mRNA levels and prognostic utility of KLKs and protease‐associated receptors (PARs), which influence

The impact of a new intervention for venous leg ulcers: A within‐patient controlled trial

open access: yesInternational Wound Journal, Volume 20, Issue 6, Page 2260-2268, August 2023., 2023
Abstract A major obstacle to the development of new treatments for venous leg ulcers is the difficulty in generating evidence for their effectiveness. Randomised controlled trials using complete healing as the endpoint are seldom powered to be successful, owing to the heterogeneity of cohorts.

No evidence of light inhibition on aerobic methanotrophs in coastal sediments using eDNA and eRNA

open access: yesEnvironmental DNA, Volume 5, Issue 4, Page 766-781, July 2023., 2023
We tested whether light reaching the seafloor can inhibit methanotrophic activity in the sediment surface. We found no difference between dark and light treatments for a shallow and a deep coastal site in pore‐water CH4 concentrations, relative abundance of aerobic methanotrophs, or the number of RNA transcripts related to methane oxidation.

The roles of proteases in prostate cancer

open access: yesIUBMB Life, Volume 75, Issue 6, Page 493-513, June 2023., 2023
Abstract Since the proposition of the pro‐invasive activity of proteolytic enzymes over 70 years ago, several roles for proteases in cancer progression have been established. About half of the 473 active human proteases are expressed in the prostate and many of the most well‐characterized members of this enzyme family are regulated by androgens ...

Rhesus macaques compensate for reproductive delay following ecological adversity early in life

open access: yesEcology and Evolution, Volume 12, Issue 1, January 2022., 2022
The Cayo Santiago rhesus macaque population presents a novel reproductive strategy where females experiencing major natural disasters early in life overcome their initial reproductive penalty and exhibit no major negative fitness outcomes. Such strategy suggests that investing more energy into development and maintenance at younger ages allows long ...

Environmental drivers of Sphagnum growth in peatlands across the Holarctic region

open access: yesJournal of Ecology, Volume 109, Issue 1, Page 417-431, January 2021., 2021
We measured growth in two species from the peat forming bryophyte genus Sphagnum (peat mosses) across the Holarctic. Employing structural equation models, we explored how indirect and direct drivers, such as weather variables, PAR, water table, nitrogen and vascular plant cover affect growth.

Spatio-Temporal Variation in AOD and Correlation Analysis with PAR and NPP in China from 2001 to 2017

open access: yesRemote Sensing, 2020
Atmospheric aerosols can elicit variations in how much solar radiation reaches the ground surface due to scattering and absorption, which may affect plant photosynthesis and carbon uptake in terrestrial ecosystems.

Antiproliferative and cytotoxic activities of furocoumarins of Ducrosia anethifolia

open access: yesPharmaceutical Biology, 2018
Context: Phytochemical and pharmacological data on Ducrosia anethifolia (DC.) Boiss. (Apiaceae), an Iranian medicinal plant, are scarce; however, furocoumarins are characteristic compounds of D. anethifolia.
