The main mechanism of toxicity for fast-dissolving nanoparticles (NPs) is relatively simple as it originates from the intrinsic toxicity of their constituent elements rather than complicated surface reactivity. However, there is little information about the compared toxicity of fast-dissolving NP and its constituent ion, which is essential for understanding the mechanism of NP toxicity and the ...

The interface of a 1 : 2 molar choline chloride/ethylene glycol deep eutectic solvent with a glassy carbon electrode has been investigated by polarization modulation reflection-absorption spectroscopy (PM-IRRAS). Temporal spectral changes at open circuit potential show the experiments to be surface sensitive and indicate slow adsorption of electrolyte molecules on the electrode surface. In situ...

chloride or cadmium nitrate. However, the complexation was secondary in relation to ninhydrin-amino acid reaction [4]. At the end of the 1990’s, a new component named 1,2-IND (1,2-indanedione) was applied, which reacted with amino acids and with DFO, whereby the reaction product exhibited fluorescent properties [5, 6]. The follow-up scientific activity within this scope was focused on the optim...

Understanding and controlling the surface chemistry of colloidal quantum dots (QDs) are essential steps toward improving their opto-electronic properties tailoring material for specific applications. For oleylamine–chloride co-passivated InP QDs synthesized using di-ethylaminophosphine (DEAP), knowledge possible exchange reactions effect on QD is still very limited. In this work, we address iss...

Choline. Choline has been identified as a required nutrient for many species including humans, chicks, and pigs. Choline is found in low concentrations in most feeds, ranging from 0.04% in corn silage and alfalfa hay to 0.3% in protein sources such as soybean meal and cottonseed meal (DM basis). Its low concentrations in feeds are indicative of the low amounts required by livestock (e.g. 3 g/da...

Choline is important for the synthesis of acetylcholine, an integral neurotransmitter involved in memory formation. In order to investigate the effect of choline supplementation on memory consolidation, the study utilized a T-maze to facilitate passive avoidance learning and memory in young female Sprague-Dawley rats. Rats were placed in two groups; choline-supplemented that received choline ch...

Nutritional deprivation of proteins decreases the protein kinase C (PKC) activity in rat lung. The activity of (PKC) is influenced by lipid metabolism. Changes in PKC activity may influence phosphorylation of its substrate proteins in the tissues. Therefore, alterations in phospholipid metabolism and PKC mediated protein phosphorylation in dietary protein deficiency in rat lung were envisaged. ...

Aquaporins play a major role in governing the movement of water between neighboring cells during seed germination and are major players in response to abiotic stress conditions that affect water availability. Seeds of pea (Pisum sativum L. cv. Arkel) were used for studying cell growth, expression and function of aquaporins during seed imbibition, radicle emergence and growth.Water channel funct...

Flocculation is one of the principal steps in biodiesel production from microalgae. Eight different flocculants were analysed for their efficiency of flocculation of marine microalga, Nannochloropsis oculata. Maximum flocculation was observed as 93.80 and 87.33% with FeCl3 and Fe2(SO4)3 at a concentration of 0.4 and 0.6g/L respectively at 180min. Zinc salts achieved second maximum efficient flo...

Central administration of acetylcholine or nicotine to rats induces changes in blood pressure and heart rate via central chol inoceptor activation (1, 2). Physostigmine a cholinesterase inhibitor also modifies blood pressure and heart rate (3, 4). Thus, central cholinergic mechanisms may be physio logically involved in the central control of cardiovascular function. In the present experiments, ...
