High impact information on carbamide

• Antihistamine reduced the flushing response by 40% and decreased the pulse rate from 40 minutes onward after ethanol infusion subsequent to calcium carbamide dosing [6].
• In conclusion, we found that neither reduction of the individual amide linkages between residues 6-11 and 12-13 nor introduction of a carbamide moiety in lieu of the side chain of Ser7 led to CRF antagonists [7].

Chemical compound and disease context of carbamide

• Biochemical changes in urine (a low osmolality, low concentrations of carbamide and creatinine, and extremely low sodium concentrations) and in plasma (aldosteronism) similar to those found in nursing sickness were elicited in the nursing dams [11].

Biological context of carbamide

• The heterogeneous hydrolysis reactions were carried out in glass reaction tubes under nitrogen with initial polyurea loadings of 2 g/L in deionized water or buffer solution [12].
• The cis amino alcohol functionality in vancosamine was introduced by the electrophilic cyclization of the isourea, followed by hydrolysis of the resulting oxazoline [13].
• The lower level of serum zinc, copper and sodium may be due to the osmotic diuresis and consequent polyurea of diabetes [14].
• Termination of hypertensive pregnancies with intra-amniotic urevert [15].
• In healthy test persons a single dose of 1.5 g bromisovalerianyl carbamide has no demonstrable influence on the system of hemostasis [16].

Anatomical context of carbamide

• The concentration of free AA and U in the postabsorptive region of the intestine (cecum) of rats consuming antibiotics was greater than when antibiotics were not consumed [17].
• Hemolysate-filled polyethyleneimine and polyurea microcapsules as potential red blood cell substitutes: effect of aqueous monomer type on properties of the prepared microcapsules [18].
• The purpose of this study was to record the time-course diffusion of hydrogen peroxide through human dentin from a peroxide carbamide gel designed for the walking bleach technique in order to determine its optimal renewal time [19].
• Glucose oxidase was microencapsulated within polyurea membranes by the interfacial polymerization method and the stability to heat of the encapsulated enzyme was examined [20].

Associations of carbamide with other chemical compounds

• Microencapsulation of osmium tetroxide in polyurea [21].
• Palladium(II) acetate microencapsulated in polyurea (MC-[Pd]) is an economical and versatile heterogeneous catalyst for a range of phosphine-free cross-coupling reactions in both conventional solvents and supercritical carbon dioxide (scCO2); the catalyst can be recovered by a simple filtration and recycled up to four times [22].
• Finally, the hydrolysis reaction of cyanamide or carbodiimide leading to urea or isourea formation is not observed under our experimental conditions [23].
• The bioconversion of progesterone to 11 alpha-hydroxyprogesterone with these polyurea-coating alginate-entrapped Aspergillus ochraceus cells was investigated using different organic solvents in biphasic media [24].
• Liver enzymes, serum creatinine and carbamide levels in each case were within the normal range (G0) [25].
• To further validate the direct interaction model we show that, in urea and guanidinium chloride solutions, unfolding of an unusually stable helix (H1) from mouse PrPC (residues 144-153) occurs by hydrogen bonding of denaturants to charged side chains and backbone carbonyl groups [26].
• In this procedure, urea plays a double role as a nitrogen/carbon source and stabilizing agent (necessary for the nanoparticle dispersion) [27].
• Urea uptake was less efficient than nitrate uptake, and urea grown-plants presented signs of N starvation [28].

Gene context of carbamide

• Expressed relative to the output of carbamide the output of urinary EGF IR increased with a median factor of 2 following the run [29].
• Synthesis and biological evaluation of potent glycosidase inhibitors: N-phenyl cyclic isourea derivatives of 5-amino- and 5-amino-C-(hydroxymethyl)-1,2,3,4-cyclopentanetetraols [30].
• The freezing behaviour of water in polyurea microcapsules was studied through DSC (differential scanning calorimetry) and ESR (electron spin resonance) measurements under a non-equilibrium condition to show that supercooling of water becomes more noticeable with decreasing droplet size of the liquid [31].
• Influx of 15N-labeled urea in atdur3-1 and atdur3-3 showed a linear concentration dependency up to 200 microM external urea, whereas influx in wild-type roots followed saturation kinetics with an apparent Km of 4 microM [32].

Analytical, diagnostic and therapeutic context of carbamide

• During the intramuscular injections the volunteers felt only localized pain; some reported drowsiness, increased thirst and polyurea [33].
• CONCLUSION: These results suggest that tooth bleaching with carbamide (urea) peroxide (using commercially available concentrations) does not increase the susceptibility of enamel to acid erosion or caries [34].
• Conclusion: It was verified that the dentifrices containing carbamide or hydrogen peroxide along with alumina + silica and calcium carbonate, respectively (groups 4 and 5), produced minor changes in Ra when compared with the control group and with those dentifrices containing bicarbonate (groups 2 and 3) [35].
• The objective of this investigation was to evaluate the effect on dental caries experience of using carbamide polyol chewing gum as a supplement to standard oral hygiene procedures for schoolchildren in a developing country (Madagascar) [5].
