Synthesis of polymeric ladders by topochemical polymerization

Two polymeric ladders were synthesized by topochemical polymerization. The critical assemblies with multiple reactive centers were characterized by single crystal X-ray diffraction. Approximately 64% and 70% of the mass of the two polymeric ladders can be derived from biomass, respectively.

An unsaturated hydrogen bonded network generated from three-fold symmetric carbamates

A new crystalline sheet spontaneously assembled under mild conditions from tri-carbamates. The discovery of the unsaturated hydrogen bonded sheet further demonstrated the variety and adaptability of the sheet structures.

[Nutritional management of neonates and infants with cystic fibrosis of the pancreas detected at birth]

From a systematic neonatal screening for cystic fibrosis in the Basse-Normandie area and to prevent disorders of the intestinal transit related to malabsorption, neonates then infants were given a semi-elemental hypercaloric diet, with supplements in nitrogen, MCT, minerals, vitamins and low in LCT. Diets were adjusted every month during a consultation using clinical and biological parameters. Results in the first 14 children showed that clinically as well as biologically, these children may remain within the normal range, avoiding the previously reported growth retardation and mineral or vitamin deficiencies. This procedure should allow an improvement in the quality of life and prognosis of such children, by maintaining adequate nutritional status.
