INTRODUCTION The current report detailed an investigation of melamine-linked urinary stones in children exposed to contaminated formula. MATERIAL AND METHODS A total of 1062 children fed with melamine-contaminated infant formula were screened for urinary stones. Sixty healthy children without melamine exposure were recruited as a control group. Ultrasonography of the urinary tract system was ...

254 Iranian Journal of Kidney Diseases | Volume 3 | Number 4 | October 2009 addition, the pathological process in the affected pediatric cases is owing to the acute obstruction from melamine crystal that is unlikely to cause proteinuria. Therefore, the rational for screening for proteinuria in pediatric cases exposed to melamine is not supported. Some limitations of this work should be noted. F...

Porphyrins appended with four rigid hydrogen bonding motifs on the meso positions were synthesized and self-assembled into a cofacial cage with four complementary bis(decyl)melamine units in dry solvents. The hydrocarbon chains on the melamine mediate the formation of nanofilms on surfaces as the solvent slowly evaporates.

The structure of a 1:1 complex of uracil and melamine obtained by cocrystallization has been investigated. The structure involves hydrogen bonded layers with apertures stacked along the a and b directions giving rise to channels, unlike the complex of cyanuric acid with melamine.

We here report a novel fluorescent method for the detection of melamine based on the high fluorescence quenching ability of gold nanoparticles. The fluorescence was significantly quenched via fluorescence resonance energy transfer when fluorescein molecules were attached to the surface of gold nanoparticles by electrostatic interaction. Upon addition of melamine, the fluorescence was enhanced d...

BACKGROUND Melamine-contaminated milk powder was the cause of the 2008 outbreak of urolithiasis in young children and infants in China, but the prognosis of these children remains unknown. We hypothesized that urolithiasis induced by melamine-contaminated milk powder may be associated with secondary renal injury. METHODS A total of 8335 children (≤6 years old) with a history of consuming mela...

By the reaction of Benzoin with melamine and 5-aminosalysilc acid a new Schiff base is obtained legends Mn++, Zn++, Ag + salts leads to complexes [M (L)2 ] X at PH=7-6, PH=9-10, L= BMA, BMS M= Mn++ Zn++ +, Several chemical physical measurements, such as melting point, molar conductivity, magnetic properties, well FT-IR spectroscopy, UV-VIS spectroscopy element analysis (C.H.N.), (1 H-NMR)spectr...

melamine is a new risk of urinary stones. gansu province is a heavily affected area and has large population and underdeveloped economy. we hypothesized that number of family members and family income may play significant roles in the formation of urinary stones. a case-control study was performed among 190 infants. results showed that the case group had less numbers of family members than the ...

Melamine, a synthetic nitrogenous product found in many industrial goods and even in fertilizer destined for use in growing crops for human consumption, was recently found to have been added to foods in China — including many different powdered infant formulas1 — to increase their measured, but not biologically available, protein content. Melamine is largely not degraded in humans, although sev...

For the development of a cost-effective melamine-modified urea formaldehyde resin (MUF), the study evaluated the effects of reaction pH and melamine content on resin properties and bond performance of the MUF resin adhesive systems. Eight resins, each with three replicates, were prepared in a factorial experiment that included two formulation variables: two reaction pHs (i.e., 4.5 and 8.0) and ...
