Oxygen consumption from air and water, ammonia and urea‐N excretion, and Na+ fluxes during progressive aquatic hypoxia in Amazonian armoured catfish Pterygoplichthys gibbiceps and Pterygoplichthys pardalis

Journal of Fish Biology, EarlyView.
Abstract The Amazonian loricariid fish Pterygoplichthys gibbiceps, from the Rio Negro, and Pterygoplichthys pardalis, from the Rio Solimões, are facultative air‐breathers that can use the stomach as an air‐breathing organ. Measurement of oxygen uptake under progressive aquatic hypoxia revealed a relatively high hypoxia resistance of both species.

Measurement of the 3He mass diffusion coefficient in superfluid 4He over the 0.45-0.95 K temperature range

, 2001
We have measured the mass diffusion coefficient D of 3He in superfluid 4He at temperatures lower than were previously possible. The experimental technique utilizes scintillation light produced when neutron react with 3He nuclei, and allows measurement of

Joint effects of elevated copper and temperature in juvenile Tambaqui exposed in black and white waters of the Amazon

Journal of Fish Biology, EarlyView.
Abstract This study aimed to investigate how exposure to elevated water temperature and metal concentration jointly affect the physiology of Amazonian fish. Aboard a research vessel in the Amazon, we evaluated the effects of water temperature (river T°C at 31.5°C and a + 4°C increase to 35.5°C) and of 3‐h copper (Cu) exposure (up to 600 μg/L) in ...

Functional Characterization of the Cat and Dog Wild‐Type and Mutant MDR1 Carrier Proteins and Frequency of the MDR1 Gene Mutation in 800 Cats From Germany

Journal of Veterinary Pharmacology and Therapeutics, EarlyView.
ABSTRACT The ATP‐binding cassette transporter MDR1 P‐glycoprotein (syn. ABCB1) is an efflux carrier at the cell membrane that regulates drug absorption, distribution, and elimination. At the blood–brain barrier, MDR1 restricts brain entry of potentially neurotoxic drugs, such as ivermectin. In dogs and cats, MDR1 (syn.

Can biochar amendment alter the sorption of glyphosate in the Australian Vertosol soil system?

Soil Security
Biochar has the potential to adsorb glyphosate, a potential groundwater pollutant in areas having indiscriminate use in farming activities. Batch sorption experiments were conducted at the University of Sydney, Australia.

Expression of a Bacterial Trehalose 6‐Phosphate Synthase Gene otsA in Camelina sativa Seeds Promotes the Channelling of Carbon Towards Oil Accumulation

Plant Biotechnology Journal, EarlyView.
ABSTRACT Improving seed oil yield is essential for developing Camelina sativa as a sustainable biofuel crop. Fatty acid synthesis depends on the production of acetyl‐CoA from photosynthetically derived sugars. Trehalose 6‐phosphate (T6P), a proxy for sucrose availability, can link sugar status to plant growth and development. Synthesised by trehalose 6‐

Greater Resistance to Drought‐Induced Embolism Is Linked to Higher Yield Maintenance in Soybean

Plant, Cell &Environment, EarlyView.
ABSTRACT With increasing drought events worldwide, crop breeding must focus on drought resistance to maintain crop yields. To ensure a high level of gas exchange and growth, plants need to maintain the integrity of their vascular system under drought conditions. While the impact of drought‐induced vascular damage on tree species is well‐documented, its

SALT OVERLY SENSITIVE 1 Na+/H+ Exchanger Operates in Mature Root Zone and Is a Major Contributor to Root Na+ Exclusion During Shoot‐to‐Root Na+ Recirculation

Plant, Cell &Environment, EarlyView.
ABSTRACT The Na+/H+ antiporter SALT OVERLY SENSITIVE 1 (SOS1) is a key component of Na+ exclusion and plant salt tolerance. Although previous studies have suggested that SOS1 functions in both the root apex and mature root zone, their contributions remain unclear due to limited methodological resolution and originated mostly from transcriptional ...
