Rakentaako Chen evaluaatiotutkimukselle sen tuolista puuttuvat kaksi jalkaa - vai vahvistaako hän jo olemassa olevaa? Entä selkänoja? Tarvitseeko evaluaatiotutkimus laajemmasta näkökulmasta oman irtotuolin sijasta penkin vai torin, jolla ei ole edes penkkejä?

Abstract:Does evaluation need a three-legged stool? Should there be even more legs in the stool for evaluation or should evaluation have a bench? Or would it be best or more practical for evaluation if it was a square or marketplace without any kind of stools or bench? What is Huey-Tsyh Chen doing for evaluation in his new "Practical evaluation"?

Ácido ent-16alfa,17-diidroxicauran-19-óico isolado de Ouratea semiserrata e os desafios estereoquímicos dos carbonos quirais C-4 e C-16

Phytochemical investigation of the leaves and branches of a specimen of Ouratea semiserrata led to the isolation and characterization of ent-16alpha,17-dihydroxykauran-19-oic acid, along with other natural products. This diterpenoid and its derivatives were used to unambiguous ¹H and 13C chemical shifts assignments and to indicate some mistake data described in the literature as consequence mainly of the stereochemicals of the chiral carbons C-4 and C-16. The HRMS spectra were also analysed.

Mono and diterpenes from seeds of Xylopia sericea

A monoterpene, 3beta,6beta-dihydroxy-p-menth-1-ene has been isolated from the seeds of Xylopia sericea along with four kaurane, one beyerene, one atisene and four trachylobane diterpenoids, including the trachyloban-18- and 19-methyl esters. The X-ray crystal structure of methyl ent-trachyloban-18-oate was determined in order to make an unambiguous distinction between the 18- and 19-esters. The 13C NMR data for ent-15alpha-hydroxy-trachyloban-19-oic acid has been revised.

Alcaloides e outros constituintes de Xylopia langsdorffiana (Annonaceae)

The phytochemical investigation of Xylopia langsdorffiana led to the isolation of corytenchine, xylopinine, discretamine, xylopine, ent-atisan-16α-hydroxy-18-oic acid, 13² (S) hydroxy-17³-ethoxyphaephorbide and quercetin-3-α-rhamnoside. Their structures were assigned based on spectroscopic analyses, including two-dimensional NMR techniques. Antioxidant activities of discretamine were measured using the 1,2-diphenyl- 2-picryl-hydrazyl (DPPH) free radical scavenging assay.

Abordagem fisioterapêutica na dor pós-operatória: a eletroestimulação nervosa transcutânea (ENT)

This study provides an update on the use of Transcutaneous Eletric Nerve Stimulation (TENS) as a non-pharmacological resource of postoperative pain relief. National and international references regarding the use of TENS for the relief of postoperative pain had been selected, highlighting its mechanism of action, parameters of application, contraindications, side-effect and results. TENS is a non-pharmacological resource that has its mechanism of action based on the gate theory. It consists of a device that emits electric impulses in the skin through electrodes. It is a low cost technique, easily applicable, presents few collateral effects, good effectiveness related to the reduction of the painful perception, allowing early mobilization and reduced pharmacological analgesic consumption. TENS represents another option in the control of postoperative pain and should be inserted in a multiprofessional context.
