“Polygonum cuspidatum is a potent anti-oxidant herb that is well known for its various bioactivities. The current study investigates which compound group is most effective, to establish the key compound groups for quality assessment, especially in terms of neuroprotective effects. The roots of P. cuspidatum were extracted with 85% methanol and fractionated with hexane, ethyl acetate, n-butanol and water. Each fraction was applied to an in vitro radical scavenging assay, a lipid peroxidation assay in brain homogenates and an in vivo
assay using a transient focal cerebra ischemia model induced by a middle cerebral artery occlusion in a Sprague-Dawley rat. The ethyl acetate fraction was the most selleck effective fraction in both in vitro and in vivo assays, having the highest stilbene and anthraquinone contents. These results suggest that https://www.selleckchem.com/products/tubastatin-a.html stilbenes and anthraquinones may be key compound groups for the quality assessment of the anti-oxidative and neuroprotective effects of P. cuspidatum.”
“Objective: Intraventricular haemorrhage (IVH) is a major problem
in premature infants. Our objective is to assess the early predictive value of vascular endothelial growth factor (VEGF) for development of IVH and management of its squeal in preterm neonates. Methods: We prospectively studied 150 preterm neonates (PT) less than 34 weeks gestation. Fifty of them completed the study. 30/50 developed IVH during follow up, and 20 did not. First 24 hours, and 3rd day serum samples were collected. Cerebrospinal fluid (CSF) samples were withdrawn for 10 IVH patients. Results: Serum VEGF; both samples were increased in IVH compared to non-IVH group (P = 0.001). PHVD-group (n = 10)
had EPZ015666 order higher VEGF in both samples than resolved IVH (P = 0.004), (P = 0.005). While, VEGF increased in the IVH group 2nd sample compared to 1st (P = 0.000), it decreased in non-IVH group, P = 0.033). Each 1 unit increase in 1ST VEGF increased the risk of occurrence of IVH by 1.6%. 3rd day VEGF at a cut-off value of 135 pg/ml is 96% sensitive and 100% specific to predict PHVD. Serum VEGF inversely correlated with TLC, pH, PO2 and HCO3, and positively correlated with PCo2 and FiO(2). Conclusion: Serum VEGF predicts development of IVH and PHVD in PT neonates. Also, high CSF level of VEGF could predict the need for permanent shunt placement.”
“A new 28-norolean-12,17-diene triterpene lantigdienone (1) oxidised at C-11 and C-22 has been isolated from the aerial parts of Lantana camara, along with two known compounds, camarinin (2) and camangeloyl acid (3). The structure of compound 1 was elucidated as 3,25-epoxy-3-hydroxy-22-[,dimethylacryloyloxy]-11-oxo-28-norolean-12,17-diene, with the help of spectral studies.”
“Objective: Preterm infants experience frequent cardiorespiratory events (CREs) including multiple episodes of apnea and bradycardia per day.
