A copper-catalyzed methodology for the preparations of N-aroylated sulfoximines from methylarenes was herein demonstrated. The transformation proceeded with the assistance of external oxidant tert-butyl hydroperoxide, requiring for no additional solvents or ligands. The good compatibility and high efficiency of the newly developed protocol were well described by 21 examples and up to 91% yields. Moreover, the protocol was proved by the control reactions to proceed through a radical pathway. © 2017 Taylor & Francis

This article reviews current knowledge of the mechanisms underlying the initial hemorrhage and secondary blood-brain barrier (BBB) dysfunction in primary spontaneous intracerebral hemorrhage (ICH) in adults. Multiple etiologies are associated with ICH, for example, hypertension, Alzheimer's disease, vascular malformations and coagulopathies (genetic or drug-induced). After the initial bleed, there can be continued bleeding over the first 24 hours, so-called hematoma expansion, which is associated with adverse outcomes. A number of clinical trials are focused on trying to limit such expansion. Significant progress has been made on the causes of BBB dysfunction after ICH at the molecular and cell signaling level. Blood components (e.g. thrombin, hemoglobin, iron) and the inflammatory response to those components play a large role in ICH-induced BBB dysfunction. There are current clinical trials of minimally invasive hematoma removal and iron chelation which may limit such dysfunction. Understanding the mechanisms underlying the initial hemorrhage and secondary BBB dysfunction in ICH is vital for developing methods to prevent and treat this devastating form of stroke. © 2014 Keep et al.; licensee BioMed Central Ltd.

The discrimination of Pt-GG adducts by mismatch repair proteins, DNA damage-recognition proteins, and translation DNA polymerases was thought to be vital in determining the toxicity, efficacy, and mutagenicity of platinum anti-tumour drugs. Studies on cis-diammine-Pt-GG (from cisplatin and carboplatin) and trans-R,R-diaminocyclohexane (DACH)-Pt-GG indicated that these proteins recognized the differences in conformation and conformational dynamics of Pt-DNA complexes. However, the structural basis of enantiomeric DACH-Pt-GG forms is unclear. Molecular dynamics simulations results presented here reveal that the conformational dynamics between trans-R,R-DACH-Pt-GG, trans-S,S-DACH-Pt-GG, cis-DACH-Pt-GG and undamaged DNA are distinct and depend on the chirality of DACH though their major conformations are similar. Trans-DACH-Pt was found to be energetically favoured over cis-DACH-Pt to form DNA adducts. Moreover, oxaliplatin and its cis-DACH analogues were found to preferentially form hydrogen bonds on the 3′ side of the Pt-GG adduct, whereas the S,S-DACH-Pt preferred the 5′ side. A three-centre hydrogen bond formed between cis1-DACH-Pt and DNA was observed, and the differences in hydrogen bond formation are highly correlated with differences in DNA conformational dynamics. Based on these results, it is suggested that the different bioactivities of oxaliplatin and its enantiomeric analogues were controlled by the difference in hydrogen bonds formation dynamics between DNA and the Pt moiety. Our molecular dynamics approach was demonstrated to be applicable to the study of stereoisomer conformations of platinum-DNA model, thereby suggesting its potential application as a tool for the study and design of new effective platinum-based drugs. © 2016 CSIRO.

Chinese governmental sectors have been investing lots of money in setting up new institutions for long-term care (LTC) in rural China to respond to the predicted increasing and urgent needs of the growing number of aging people. However, very few have identified that many ethnic minority groups have been enjoying their traditional home-based LTC systems, which are cost-effective and have been working really well for generations. This article reports on a study on LTC needs and provisions for the Dai, one of the ethnic minority groups in rural areas of southwest China, in Yunnan (Province). A randomized sample was drawn from 12 villages in Ruili, a county 752 km from Kunming, the capital city of Yunnan. Totally, 187 elderly persons were interviewed intensively. Activities of daily living were measured as the core indicator for understanding LTC. The research revealed that there is a significant disparity between the needs of the villagers and provisions from the different levels of government. There is an urgent need to reexamine the allocation of public resources for the aged. Traditional culture and practices of caring for the elderly, and practices in LTC of different ethnic groups, must be carefully considered. © 2016 Family Medicine and Community Health.

Ethnopharmacological relevance: Raw and processed Polygoni Multiflori Radix (PMR) are used in the prevention and treatment of non-alcoholic fatty liver disease (NAFLD), hyperlipidemia or related diseases. However, few researches compared the activities of raw and processed PMR on lipid metabolism regulation. Moreover, the active substances of Polygonum multiflorum are still not clearly elucidated. Materials and methods: In this research, a sensitive, accurate and rapid in vitro model, steatosis hepatic L02 cell, was applied to compare the relative activities of raw and processed PMR on lipid metabolism regulation. Furthermore, the lipid regulation activities of emodin, physcion and 2,3,5,4′-tetrahydroxy-stilbene-2-O-β-d-glucoside (TSG) were evaluated. The steatosis L02 cells were obtained after cultured with 1% fat emulsion-10% fetal bovine serum (FBS)-RPMI 1640 medium for 48 h. Contents of total cholesterol (TC), triglyceride (TG) and low-density lipoprotein cholesterol (LDL-C) in L02 cells are evaluated after exposure. Results: The intracellular TG contents were increased from 16.50 ± 1.29 mmol/L to 34.40 ± 1.36 mmol/L in steatosis L02 cells, while the intracellular contents of TC were increased from 5.07 ± 1.80 mmol/L to 11.79 ± 0.54 mmol/L. Water extract of raw PMR showed much remarkable TG-regulation and TC-regulation effects than its processed products. Emodin displayed the best TG regulation activity while TSG showed the best TC regulation activity. At the same time, the exposure of emodin and physcion could reduce the LDL-C contents in steatosis L02 cells. Conclusions: On account of these in vitro results, raw PMR might have more satisfactory effects in clinic treatment of NAFLD or hyperlipidemia characterized by the elevation of cholesterol than processed PMR. © 2011 Elsevier Ireland Ltd.

Adulteration of walnut oil with sunflower oil is a major issue for the walnut oil industry. In this paper, the potential use of total synchronous fluorescence (TSyF) spectra to differentiate walnut oil from sunflower oil and synchronous fluorescence spectra combined with multivariate analysis to assess the adulteration of walnut oil is demonstrated. TSyF spectra were acquired by varying the excitation wavelength in the region 250-700 nm and the wavelength interval (Δλ) in the region from 10 to 100 nm. TSyF contour plots for walnut oil, in contrast to sunflower oil, show an extra fluorescence region in the excitation wavelength lower than 280 nm. Fifty-one oil mixtures were prepared by adulterating walnut oil with sunflower oil at varying levels (0-100 %). The partial least-squares regression model was used for the quantification of adulteration using wavelength intervals of 20, 40, 60 and 80 nm. This technique is useful for the detection of sunflower oil in walnut oil at levels down to 0.3 % (v/v) in just 2.5 min using an 80-nm wavelength interval. © 2013 Springer Science+Business Media New York.

Background: In the liver, eNOS appears to have a central role in protecting against ischemia/reperfusion (I/R) injury. We hypothesized that tetrahydrobiopterin (BH4) would protect livers subjected to I/R injury by coupling with eNOS. Methods: Chinese Kun Ming (KM) mice were subjected to 60 min of 70% hepatic ischemia 30 min after the administration of BH4 or saline. After reperfusion, survival was evaluated. The histologic appearance and ALT, BH4, nitrite/nitrate, 8-isoprostane, and eNOS protein expression levels were measured. Results: The 1-wk survival rate was 66.67% in the BH4 group and 33.33% in the saline group. The serum ALT values in the BH4 group 1, 3, 6, 12, and 24 h after reperfusion were significantly lower than those of the saline group. A histologic examination of the liver revealed only a small necrotic area in the BH4 group as opposed to massive necrosis in the saline group. The percentage values of the hepatic necrotic area 24 h after reperfusion were significantly less for the BH4 group than for the saline group. The nitrite/nitrate levels in the liver tissue were significantly increased by ∼2-fold in the BH4 group compared with the saline group. The free radical indicator 8-isoprostane was reduced approximately 50% in the BH4 group compared with the saline group. Western blotting showed that the level of eNOS protein between the groups was not significantly different. Conclusions: BH4 significantly improved the survival rate by reducing liver failure. This was supported by the histologic findings, and the mechanism was explored. According to the results, we suggest that BH4 prevents liver damage from I/R injury by attenuating reactive oxygen species and increasing NO synthesis, and might provide a novel and promising therapeutic option for preventing I/R injury. © 2012 Elsevier Inc.

Metal-organic frameworks (MOFs) have received great attention because of their unusual properties and fascinating structures in separation sciences. However, to the best of our knowledge, there has been no attempt to utilize chiral MOFs as stationary phases in packed-CEC. Here, a chiral MOF [In3O(obb)3(HCO2)(H2O)]·solvent (4,4′-oxybisbenzoic acid) was explored as the chiral stationary phase in packed-CEC for separation of chiral compounds and isomers. The fabricated [In3O(obb)3(HCO2)(H2O)]·solvent packed capillary columns gave fast enantioseparation of (±)-hydrobenzoin, (±)-1-phenyl-1,2-ethanediol, and clenbuterol within 3 min in CEC. Besides, the baseline separations of nitrophenol isomers within 6 min were also achieved. The RSDs for the retention time of run-to-run, day-to-day, and column-to-column reproducibility were 1.51-3.63, 1.83-3.98, and 3.42-5.66%, respectively. These results demonstrate that chiral MOFs are promising for enantioseparation in CEC. © 2014 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim.

By taking "lumbar disc herniation", Chinese medicine", "acupuncture and moxibustion" as key words Chinese articles about acupuncture for lumbar disc herniation in recent 10 years were searched in three major Chinese databases of Wan fang database, VIP database and CNKI. Totally 546 relative articles were retrieved. After the elimination of invalid articles, 173 were included as valid articles with 49 main acupoints. The hierarchical clustering statistical method was used to analyze the possible rules among the former 20 acupoints. It turned out that there were 10 most common used acupoints on Bladder Meridian [Geshu (BL 17), Xiaochangshu (BL 27), Shenshu (BL 23), Dachangshu (BL 25), Pangguangshu (BL 28), Guanyuanshu (BL 26), Weizbong (BL 40), Zhibian (BL 54), Chengshan (BL 57), Kunlun (BL 60)], 2 on Gallbladder Meridian [Huantiao (GB 30), Yanglingquan (GB 34)], 2 on Governor Vessel [Yaoyangguan (GV 3), Shuigou (GV 26)], 2 on Stomach Meridian [Zusanli (ST 36), Juliao (ST 3)], 2 on Spleen Meridian [Sanyinjiao (SP 6), Xuehai (SP 10)], and the rest were extra points (Huatuo Jiaji) and Ashi points, so a conclusion could be drawn that the most common used acupoints were Bladder Meridian acupoints and supplemented by Gallbladder Meridian, Governor Vessel, Stomach Meridian, Spleen Meridian, extra points and Ashi points. The selected acupoints were most located on the lumbosacral region, leg and fewer located on the face, back and local part.

The effects of correlated time between noises on the stability of unstable state in the Logistic system are investigated. Using the steepest-descent approximation, the analytic expression for the mean first-passage time from unstable state to stable state is derived. The numerically calculated results indicate that the additive noise, the multiplicative noise and the correlated time between the additive and the multiplicative noises weaken the stability of unstable state, but the correlation between the additive and the multiplicative noises enhances the stability of unstable state. © 2012 Chinese Physical Society.
