Analysis of AtNHX1-expressing transgenic cotton under high salt conditions and in the field
… factors in crop productivity. To improve the salt tolerance in crops, one approach is to increase the solute concentration in the vacuoles of plant cells by sequestering sodium ion (Na+) into the vacuoles of plant cells. Consequently, it would reduce the toxicity of high Na+ in the cytoplasm …

The Effect of High Salt Intake on Betaine-Homocysteine S-Methyltransferase Expression in the Guinea Pig
… requiring the accumulation of betaine, such as high salt intake. BHMT is expressed in the livers of mammals and only a few species such as pig, guinea pig, and primates (including humans) have been shown to express BHMT in the kidney. Immunodetection methods were used to demonstrate that humans …

Maternal High-Salt Diet During Pregnancy in Sprague Dawley Rats Programs Exaggerated Stress-Induced Blood Pressure and Heart Rate Responses in Adult Female Offspring
… study, pregnant rats were fed a 0.7% NaCl normal salt (NS) diet or an 8% NaCl high salt (HS) diet throughout pregnancy. Adult offspring were fitted with radiotelemetry probes to continuously measure blood pressure and heart rate. Rats were placed in restraining cages to test for a programmed acute …

Differences in the expression of opioid peptides in Dahl salt-resistant and salt-sensitive rats
The Dahl strain of genetically salt-resistant (R) and salt-sensitive (S) rats affords an opportunity to explore mechanisms for the development of hypertension and the consequences, as well as sensitivity or resistance, of salt-induced hypertension. Because of the evidence that opioid peptides and …

ISOLATION OF ELECTRON TRANSPORT COMPONENTS FROM MICROCYSTIS AERUGINOSA AND OSCILLATORIA SP
… transport chain provides a useful model for higher plant systems. In this project, cytochrome c 553, plastocyanin and ferredoxin, all water-soluble components of the cyanobacterial electron transport chain, were isolated and purified from Microcystis aeruginosa. Cytochrome c 553 was purified …

Role of the renal nerves in hypertension
High blood pressure (hypertension; HTN) is the leading risk factor for death, yet the precise causes are unclear. The nervous system is known to play a role in some forms of HTN and research has pointed to the kidneys as a likely neural target in HTN. This possibility has been strengthened by …

Dynamic combinatorial synthesis of donor-acceptor catenanes
… assembly of these [2]catenanes is promoted by a high salt concentration (1 M NaNO3), which raises the ionic strength and encourages hydrophobic association. More importantly, a mechanism that explains and predicts the structures formed is proposed, giving a fundamental insight into the role …

Physiological and Molecular Dissection of Salinity Tolerance in Arabidopsis and Maize and Nitrogen Uptake in Wheat
… with adaptation to salinity stress, enhancing high salt tolerance at seed germination, seedling, and adult plant stages. Our data also indicated that salinity tolerance conferred by the prt6 mutation is attributed to increased mRNA abundance of key transcriptional factors in ABA-dependent …

Hyperbranched polyglycerol surfactants: a modular approach
… employed as a nonionic hydrophilic material with high salt stability. In this work the HPG scaffold has been used to develop a series of different surfactants for use in industrial applications. A series of HPG surfactants have been synthesized, characterized, and tested to achieve improved …

The molecular characterisation of pregnancy-associated plasma protein-A (PAPP-A).
… performing Western blotting immunodetection at a high salt concentration (0.6M NaCl). At this salt concentration a single band of 195 kDa was immunodetected and this corresponded to the monomeric PAPP-A molecule. It was also discovered that a subset of paratopes in this antiserum reacted, under …

Risk Factors Associated with the Outcome of Hypertension Among Afro-Caribbean Ethnic Groups in the United Kingdom: A Systematic Review
… Black Caribbean heritage in the UK is markedly higher than that of the general population. Despite advancements in blood pressure management, racial and ethnic minorities continue to face significant differences in hypertension care. Aim: This systematic review aimed to evaluate the risk factors …

Physiological response to three environmental stressors predicts fitness and genome quality but not base substitution rate in caenorhabditis elegans
… nematodes exposed to three different stressors: high heat, high free radicals, and high salt. The nematodes belonged to two Rhabditid nematode species and either had unmutated genomes (ancestral control) or genomes that had accumulated. In both high heat assays, we found that heat was effective …

Investigation of different blood pressure regulating systems in kininogen-deficient BNK rats
… BNK rats were shown to progressively develop salt-sensitive hypertension by accumulation of Na+. It was believed that the kininogen-deficiency is responsible for the defective NaCl excretion leading to a cardiovascular damage. In addition to the kallikrein-kinin system (KKS), endothelin (ET) …

Factors affecting preservation of liquid and frozen ram spermatozoa
… subjected to an even more hostile environment (high salt concentrations) encountered near the melting point of ice. Therefore, the benefit of higher thaw temperatures and resulting faster thaw rates was undoubtedly due to minimizing exposure time of spermatozoa to this adverse condition.

Biological treatment of waste solutions generated from the remediation of perchlorate-contaminated waters
… streams would expose these microorganisms to high salt or ammonium concentrations and high perchlorate levels. In studying the impact of these three parameters on a mixed culture of perchlorate reducers, results showed high concentrations of salt, ammonium and perchlorate negatively affected …

Salt retention in wetland soils and effects on dissolved organic carbon export
<p>Deicing salt runoff has negative effects on ecosystems. Wetland ecosystems can act as important filters for runoff pollution (e.g., nutrients), mitigating damage to plants and microbes. Wetlands are important sinks for nutrients and pollutants (e.g., road salt) and transformation spots for many …

Effects of Multi-walled Carbon Nanotubes (MWCNTs) and Integrated MWCNTs/SiO2 Additives on Polymeric PVDF Membrane for Membrane Distillation
… of membrane was improved significantly due to higher membrane porosity, contact angle and surface roughness without extreme compromise of liquid entry pressure of water (LEPw), which could reach up to 72 psi. Further integration of MWCNTs with a small amount of SiO2 nanoparticles (NPs) showed a …
