Effect of Wettability and Adhesion Property of Solid Margins on Water Drainage

open access: yesBiomimetics, 2023
Liquid flows at the solid surface and drains at the margin under gravity are ubiquitous in our daily lives. Previous research mainly focuses on the effect of substantial margin’s wettability on liquid pinning and has proved that hydrophobicity inhibits ...

The Aquaporin Water Channels [PDF]

open access: yesProceedings of the American Thoracic Society, 2006
The topic of my talk, the aquaporins, is something that we have been studying in our lab for the last 15 years. It is not something that I anticipated when starting my career. In fact, I am a hematologist, but in science, sometimes what we find is not what we are looking for. A typical middle-aged man, I weigh 75 kg, of which 50 are water.

HPV Infection Affects Human Sperm Functionality by Inhibition of Aquaporin-8

open access: yesCells, 2020
Human sperm cells express different aquaporins (AQPs), AQP3, 7, 8, 11, which are localized both in the plasma membrane and in intracellular structures. Besides cell volume regulation and end stage of cytoplasm removal during sperm maturation, the role of

Using virtual simulation in a geographic information system to optimize abundance survey designs when logistic and biological conditions are constrained

open access: yesWildlife Society Bulletin, 2012
Estimating wildlife abundance is central to many resource and ecosystem management problems. Early statistical work on wildlife abundance estimation focused on small‐scale problems, but there is a growing need for such information at large spatial scales.

Aquaporins in Cancer Biology

open access: yesFrontiers in Oncology, 2022
Aquaporins (AQPs) are a family of transmembrane water channel proteins, which were initially characterized as a novel protein family that plays a vital role in transcellular and transepithelial water movement.

Assessing the backwater rise of floating barriers with racks for various blockages in open channels

open access: yesJournal of Engineering and Applied Science
One major risk in the stream is thought to be debris. The general effects of debris spreading have a detrimental effect on water infrastructure and water activities.

Shallow landslide susceptibility assessment in a data-poor region of Guatemala (Comitancillo municipality)

open access: yesJournal of Agricultural Engineering, 2015
Although landslides are frequent natural phenomena in mountainous regions, the lack of data in emerging countries is a significant issue in the assessment of shallow landslide susceptibility.

Structure and Function of Water Channels [PDF]

open access: yesCurrent Opinion in Structural Biology, 2002
All aquaporins are efficient water transporters, while sustaining strict selectivity, even against protons, thereby maintaining the proton gradient across the cell membrane. Recently solved structures of these membrane channels have helped us to understand this remarkable property.

Photosynthesis under far‐red light—evolutionary adaptations and bioengineering of light‐harvesting complexes

open access: yesFEBS Letters, EarlyView.
Phototrophs evolved light‐harvesting systems adapted for efficient photon capture in habitats enriched in far‐red radiation. A subset of eukaryotic pigment‐binding proteins can absorb far‐red photons via low‐energy chlorophyll states known as red forms.
