Phytochemical investigation of avocado seed material (Persea americana Mill., Lauraceae) resulted in the isolation of two glucosylated abscisic acid derivates. One of these was not known as a natural… (More)
Acrylic bone cements have been used for about 40 years to fix artificial prosthesis to bone structure. The properties of the acrylic bone cement mostly depend on the characteristics of the beads,… (More)
LysCel is a cellulose-based material in which l-lysine molecules are grafted with their amino side chains to the cellulose hydroxyl groups. This modification increases considerably the mechanical… (More)
Ammoxidation of kraft lignin was carried out in a Parr reactor using (15)NH(3) as the main nitrogen source. Reaction parameters were set up until a total nitrogen content of approximately 13 wt.% in… (More)
The hexane extracts of seeds of Ditaxis heterantha afforded two new apocarotenoids whose structures corresponded to methyl 3-oxo-12'-apo-epsilon-caroten-12'-oate (1) (heteranthin) and methyl… (More)
The production and characterization of polyhydroxyalkanoic acids (PHAs) from glucose in Pseudomonas aeruginosa ATCC 9027 is described. We determined that the synthesis of PHAs was not due to a… (More)
Nanocomposites of functionalized carbon nanotubes (CNTsf) as nanofillers, and a copolymer of star-shaped poly(ε-caprolactone) (stPCL) and poly(ethylene glycol) (PEG) as a polymeric matrix were… (More)
Bursera grandifolia and other related species have been used in traditional herbal medicine in Mexico and other Latin American countries for their analgesic, antipyretic and anti-inflammatory… (More)
This research describes the preparation of membranes with chitosan (CS) as the polymer‐ ic matrix and cellulose nanocrystals (CNC) as reinforcement. The aim was to evaluate their physical, mechanical… (More)
OBJECTIVE
To evaluate whether bilayer chitosan scaffolding (BChS) can provide a watertight dural closure and permit regeneration by fibroblasts in an experimental in vivo model.
METHODS
In the in… (More)
