The incorporation of [14C]choline chloride and [14C]glycerol into segments taken from rye (Secale cereale L., cv. Rheidal) roots was greater in segments from roots grown at 5 degrees C than in segments taken from roots growing at 20 degrees C. The incorporation was measured at the temperature at which the root had been growing. Measurements in vitro of the enzymes of the nucleotide pathway show...

We studied the transport of nitrogen mustard (HN2) by mouse hemopoietic and transplantable myeloma (Adj. PC-5 and MOPC 460D) stem cells, using gradients of tempera ture and choline chloride. Bone marrow and myeloma cells were exposed to HN2 in culture at various temperatures, washed, and tested for colony-forming efficiency. The protective effect of lowered temperatures was similar for normal m...

During perfusion of a plasma-like solution, colonic absorption rate of chloride was much higher than the secretion rate of bicarbonate (34 vs. 3.5 meq/h, respectively). This might suggest that anion exchange (Cl/HCO3) accounts for only a small fraction of total chloride absorption. However, if the colon absorbs as well as secretes bicarbonate, this reasoning would underestimate the magnitude of...

In this study, the solubility of CO2 in DEA in the presence and absence of choline chloride was reported at different temperatures of 276.15, 298.15, 313.15, and 333.15 K, and pressure range of 4-15 bar. The solubility of CO2 was evaluated using the pressure decay method in a batch isochoric stirred absorption cell. Also, the design of experiments performed with Qualitek-4 software using the Ta...

The influence of choline availability on acetylcholine (ACh) release in the hippocampus of the awake rat was investigated using the microdialysis procedure. Three treatments enhancing choline availability for basal and atropine-evoked ACh release were evaluated: acute administration of choline chloride (20 mg/kg i.p.); pretreatment of animals with nicotinamide (10 mmol/kg s.c.) 2 hr before atro...

Herein, choline chloride was loaded into PLGA nanoparticles to ensure its controlled release. Encapsulation efficiencies (EE) and loading capacities (LC) of them were determined. Also, the produced analyzed with Zetasizer, FT-IR, SEM, XRD. The surfaces functionalized by labeling three different natural lanthanide metals Europium, Gadolinium, Lutetium expand diagnostic therapeutic capabilities i...
