Green Synthesis of Silver Nanoparticles Using Flower Extract Assisted by Ultrasound Method and Its Antibacterial Activity.

Background: Green synthesis method of nanoparticles has been developed for several years. Besides providing environmental-friendly process, green synthesis of nanoparticles using plant extract provides synergistic effect of the secondary metabolite in such antibiotic activity. The study with an intensification process in nanoparticles formation is also gaining great attention.

Provision of Standardized All-in-One Parenteral Nutrition (AIO-PN) for Very Preterm Neonates: Evaluation at Room and Cold Temperatures.

Introduction: All-in-one parenteral nutrition (AIO-PN) is essential for patients with limited venous access, e.g. premature infants.

Compatibility of acetaminophen with central nervous system medications during simulated Y-site injection.

Background: The critical care patient commonly receives a lot of medications including acetaminophen and central nervous system (CNS) agents. However, research on compatibility between acetaminophen and CNS medication is still limited.

Methods: Physical compatibility was evaluated using Y-site simulation by mixing one CNS medication with 10 mg mL-1 of acetaminophen solution under aseptic conditions with a 1 : 1 ratio.

Comparación de Nutrición parenteral "todo-en-uno" frente a nutrición parenteral sin lípidos en prematuros: análisis visual, de pH y tamaño de partículas.

Objective: this study aims to investigate the physical stability of standard formulations for parenteral nutrition, with and without lipids, in one bag for preterm babies. Method: standard formulations for first-day and for second-day parenteral nutrition of preterm babies weighing 1,000 grams were prepared in triplicate. Standard all-in-one formulas for first-day and for second-day parenteral nutrition were compared with equivalent standard lipid-free formulations.

Cyclorocaglamide, the first bridged cyclopentatetrahydrobenzofuran, and a related "open chain" rocaglamide derivative from Aglaia oligophylla.

Two rocaglamide-related natural products, the previously known compound 6-demethoxy-10-hydroxy-11-methoxy-6,7-methylendioxyrocaglamide (3), and cyclorocaglamide (4), its 8b,10-anhydro analogue, have been isolated from the tropical plant Aglaia oligophylla. Compound 4 is the first bridged cyclopentatetrahydrobenzofuran natural product, and it exhibited a CD spectrum virtually opposite that of all the other rocaglamide natural products known so far, but it still has the same absolute configuration at all stereogenic centers of the basic molecular framework. This was shown unequivocally by quantum chemical CD calculations (here based on molecular dynamics-weighted force field structures) and was finally confirmed experimentally, by a "biomimetic-type" cyclization of 3 to give 4, with the expected "inversion" of the CD spectrum.
