Practical implementation of the entropy index in assessing the ecological state of water ecosystems

open access: yesВодное хозяйство России: проблемы, технологии, управление
Assessment of the biological systems’ state in case of anthropogenic impact is the most important aspect of monitoring of the surface waters’ state and pollution. The state of more than 100 water bodies of the European territory of Russia and Siberia was

Smooth lumpsucker Aptocyclus ventricosus in the northwestern Sea of Japan: distribution and some life history traits

open access: yesArchives of Polish Fisheries, 2018
This paper is focused on horizontal, vertical, and temperature-dependent distributions, size composition of bottom and mid-water trawl catches, and biomass estimations of smooth lumpsucker Aptocyclus ventricosus (Pallas) (Cyclopteridae) within the ...

SubcriticalWater – a Perspective ReactionMedia for Biomass Processing to Chemicals: Study on Cellulose Conversion as aModel for Biomass [PDF]

open access: yes, 2013
Biomass and water are recognized as a key renewable feedstock in sustainable production of chemicals, fuels and energy. Subcritical water (SubCW), or commonly referred as hot compressed water (HCW), is the water above boiling and below critical point (CP;

Survivin and Aurora Kinase A control cell fate decisions during mitosis

open access: yesMolecular Oncology, EarlyView.
Aurora A interacts with survivin during mitosis and regulates its centromeric role. Loss of Aurora A activity mislocalises survivin, the CPC and BubR1, leading to disruption of the spindle checkpoint and triggering premature mitotic exit, which we refer to as ‘mitotic slippage’.

Use of nonwettable membranes for water transfer [PDF]

open access: yes, 1970
Transfer of water through nonwettable vinyl fluoride membranes has two unique features - /1/ very low water transfer rates can be held constant by holding temperature and solute concentrations constant, /2/ the pressure gradient against which water is ...

Boosting capacitive blue-energy and desalination devices with waste heat

open access: yes, 2014
We show that sustainably harvesting 'blue' energy from the spontaneous mixing process of fresh and salty water can be boosted by varying the water temperature during a capacitive mixing process.

CDK11 inhibition induces cytoplasmic p21WAF1 splice variant by p53 stabilisation and SF3B1 inactivation

open access: yesMolecular Oncology, EarlyView.
CDK11 inhibition stabilises the tumour suppressor p53 and triggers the production of an alternative p21WAF1 splice variant p21L, through the inactivation of the spliceosomal protein SF3B1. Unlike the canonical p21WAF1 protein, p21L is localised in the cytoplasm and has reduced cell cycle‐blocking activity.

The effect of environmental stressors on the development and behaviour of larval Oryzias latipes [PDF]

open access: yes, 2020
Elevated water temperature and dissolved carbon dioxide (CO2) are two environmental stressors that freshwater organisms face in the Anthropocene. Larval fishes are particularly susceptible to elevation in water parameters, as they are often confined to ...

Reduced vascular leakage correlates with breast carcinoma T regulatory cell infiltration but not with metastatic propensity

open access: yesMolecular Oncology, EarlyView.
A mouse model for vascular normalization and a human breast cancer cohort were studied to understand the relationship between vascular leakage and tumor immune suppression. For this, endothelial and immune cell RNAseq, staining for vascular function, and immune cell profiling were employed.
