Brain tissue cysts were observed in all mice infected with the 11 isolates at day 60 post infection, suggesting these isolates are non-lethal to mice. PCR-RFLP analysis revealed that 7 isolates belonged to ToxoDB#2, 4 isolates belonged to ToxoDB#4. This is the first isolation of ToxoDB#2 and ToxoDB#4 from lambs in China. Interestingly, none of these isolates belongs to the ToxoDB#9 that is common in China. Our results suggest that the genetic diversity and population structure of T. gondii from China maybe more abundant and magical than previous speculation. V.Natural Deep Eutectic Solvents (NaDES) have been proposed as designer solvents for the green extraction of bioactive products from plants. Myrothamnus flabellifolia is a desiccation-tolerant medicinal shrub that has been widely studied for its phenolic properties; however, a NaDES-based approach for the extraction of phenolics has not been tested in this species. Our aim was thus to evaluate the extraction of phenolics from M. flabellifolia using four different NaDES with differing acidities using a non-targeted liquid chromatography-quantitative time-of-flight-tandem mass spectrometry (LC-QTOF-MS/MS) metabolomics approach. Anthocyanin pigments were quantified using targeted high-performance LC. Leaf material from M. flabellifolia was extracted in four different NaDES solutions (sucrose-fructose-glucose; proline-malic acid; sucrose-citric acid; and glucose-choline chloride), and the results were subjected to multivariate statistical analysis to evaluate the phenolic profiles of the different NaDES extracts. Tnt non-toxic solvent system that can be tailored to target particular compounds. Four undescribed bioxanthracene derivatives, dongtinganthracenes A-D, along with a previously reported analog, ES-242-3, were obtained from the solid culture broth of the fungus Penicillium sp. DT10, which was isolated from wetland soil obtained from Dongting Lake. Their structures and absolute configurations were elucidated based on extensive NMR analyses, mass spectroscopic analyses, and ECD calculations. Dongtinganthracene A represents the first 7',8'-seco-bioxanthracene produced via oxidation, and dongtinganthracenes A-D show a much higher degree of oxidation in aromatic rings compared with normal naturally occurring bioxanthracene derivatives. Dongtinganthracenes B and D and ES-242-3 exhibit cytotoxic activity, while dongtinganthracene A shows inhibitory activity against LPS-induced NO production. Chemical investigation on the root of Phlomoides betonicoides led to the isolation of six undescribed diterpenoid glycosides, phlomoidesides A-F, along with two known ones using various chromatographic techniques. The structures of these compounds were determined by extensive spectroscopic analyses (including 1D, 2D-NMR and HRMS), single crystal X-ray diffraction, and calculated 13C NMR. The glycoside modifications of phlomoidesides A-F are rare in natural products, and a plausible biosynthetic pathway for these unusual glycosides was proposed. Phlomoidesides A, D, F, and phlomisosides V, Ш were cytotoxic against three human tumor cell lines, NCI-H1975, HepG2 and MCF-7, with IC50 values ranging from 7.5 to 75.7 μM. Phlomoideside B only showed weak cytotoxicity against NCI-H1975, with IC50 of 53.0- μM. Seven undescribed labdane diterpenoids, japonicones A-G, were isolated from the aerial parts of Leonurus japonicus Houtt. Japonicones C-G contained two keto carbonyl groups in their structures attached to C-3 and C-7, which are rare for labdane diterpenoids. The structures and absolute configurations of japonicones A-G were established by means of spectroscopic analyses (HRESIMS, 1D and 2D NMR, and ECD). Their anti-inflammatory activities were evaluated by measuring their inhibitory effects on PGE2 production in LPS-stimulated RAW264.7 macrophages. Japonicones A-D and G showed inhibition of PGE2 production with IC50 values in the range of 8.62-30.71 μM (the positive control paracetamol showed an IC50 = 5.79 μM). Throughout the world, ethanol is both an important commercial commodity and a source of major medical and social problems. Ethanol readily passes through biological membranes and distributes throughout the body. It is oxidized, first to acetaldehyde and then to acetate, and finally by the citric acid cycle in virtually all tissues. The oxidation of ethanol is irreversible and unregulated, making the rate dependent only on local concentration and enzyme activity. This unregulated input of reducing equivalents increases reduction of both cytoplasmic and intramitochondrial NAD and, through the latter, cellular energy state [ATP]/([ADP][Pi]). In brain, this increase in energy state stimulates dopaminergic neural activity signalling reward and a sense of well being, while suppressing glutamatergic neural activity signalling anxiety and unease. These positive responses to ethanol ingestion are important to social alcohol consumption. Importantly, decreased free [AMP] decreases AMP-dependent protein kinase (AMPK) abolism and suppression of glutamatergic neural activity by increasing excitatory and decreasing inhibitory amino acid receptors. A point is reached (ethanol dependence) where withdrawal of ethanol results in significant metabolic energy depletion in neurons and other brain cells as well as hyperexcitation of the glutamatergic system. The extent and regional specificity of energy depletion in the brain, combined with hyperactivity of the glutamatergic neuronal system, largely determines the severity of withdrawal symptoms. TITLE Outcome of multiple cesarean sections in a tertiary maternity hospital in the United Arab Emirates. OBJECTIVE To describe the operative outcomes, clinical findings, maternal morbidity and neonatal outcome associated with increasing numbers of cesarean deliveries. DESIGN Retrospective study. SETTING Corniche Hospital, Abu Dhabi, United Arab Emirates. POPULATION The study cohort was 1008 women giving birth by cesarean section who had previously undergone one or more cesarean sections, who had a singleton pregnancy, and who were not in labor. METHODS A retrospective study was undertaken over the one-year period from January 2016 to December 2016. Women were divided into five groups according to number of previous cesarean sections. The first group comprised of women who had one previous cesarean section, the second group women who had two previous cesarean sections, the third group consequently three previous cesarean sections and the fourth group four previous cesarean sections, whereas in the fifth groupemplating elective primary cesarean delivery or attempted vaginal birth after one previous cesarean section. OBJECTIVE To identify the knowledge, attitudes and practice of women and healthcare professionals in relation to pessary use for POP. METHOD This systematic review was carried out in agreement with PRISMA recommendations. PubMed/MEDLINE, SCOPUS, Virtual Health Library, Web of Science, CAPES Periodicals and CINAHL databases were searched for studies without date or language limitations. Search strategies were developed for identifying studies examining knowledge, attitudes and practice toward vaginal pessaries use. Two reviewers independently screened titles and abstracts to identify eligible studies. Data extraction was performed independently in duplicate into a standardized form. Quality of included studies was assessed using the Joanna Briggs Institute quality assessment tool. The protocol was registered with the PROSPERO International prospective register of systematic reviews [CRD42018114236]. RESULTS Fourteen studies were included. Knowledge and practice were the main domains investigated among patientsessment of knowledge, attitudes and practice is desirable to examine the complex interactions between these three constructs, expose barriers to pessary care, and develop targeted educational interventions. OBJECTIVE Transient tachypnea of the newborn (TTN) is the leading cause of neonatal morbidity in preterm deliveries and has been reported in term small-for-gestational-age (SGA) fetuses; therefore, determination of fetal lung maturity before delivery is extremely important. Our present study aimed to evaluate the ratio of fetal pulmonary artery acceleration time to ejection time (At/Et) in uncomplicated term SGA fetuses and whether this ratio changes with TTN. STUDY DESIGN One hundred seventy-five pregnant women with uncomplicated pregnancies who delivered after 37 gestational weeks were included in this cross-sectional study. Participants were divided by birth weight percentiles into SGA (n = 86) and healthy control groups (n = 89). All participants underwent ultrasound examination to determine fetal pulmonary artery At/Et. After delivery, the neonates were grouped according to diagnosis of TTN (i.e., TTN-positive SGA group [n = 14], TTN-negative SGA group [n = 72], and TTN-negative control group [n = 86]), and the fetal pulmonary artery At/Et was compared between the two. RESULTS Maternal demographic characterizes were similar between groups. At/Et was 0.309 ± 0.181 in the SGA group and 0.348 ± 0.213 in the control group and was significantly lower in the SGA group. At/Et was 0.290 ± 0.007 in the TTN-positive SGA group, 0.313 ± 0.017 in the TTN-negative SGA group, and 0.351 ± 0.186 in the TTN-negative control group, a significant difference. Additionally fetal pulmonary artery At/Et was found to be inverse correlated with TTN. Brequinar price (-0,464 P = 0.000). The cut-off value of 0.298 provided optimal specificity of 93.0 % and sensitivity of 81.0 % for subsequent diagnosis of TTN in term SGA newborns in the neonatal period. CONCLUSION The risk for TTN increases in uncomplicated term SGA fetuses. The fetal pulmonary artery At/Et appears to be a noninvasive useful method by which to predict TTN in these fetuses. BACKGROUND AND AIM Possible Hepato-protective effects of L-carnitine have been reported in previous studies. Present study was conducted to systematically review the efficacy of L-carnitine supplementation on liver enzymes. METHODS The following databases were searched up to December 2018 PubMed, Scopus, ISI Web of Science, and the Cochrane library. Only randomized controlled trials (RCTs) evaluating the effects of L-carnitine supplementation on liver enzymes including alanine aminotransferase (ALT), aspartate aminotransferase (AST) and gamma-glutamyl transferase (GGT) were included. Pooled effect size measured using random effect model (Dersimonian-Liard). RESULTS A total of 16 studies (including 1025 participants) were included in the present meta-analysis. Pooled analysis indicated that L-carnitine supplementation significantly decreased ALT (weighted mean difference (WMD) -10.729 IU/L, 95% CI -13.787, -7.672, p  less then 0.001; I2 = 95.9%), AST (WMD -7.149 IU/L, 95% CI -9.202, -5.096, p  less then 0.001; I2 = 93.5%) and GGT (WMD -7.395 IU/L, 95% CI -9.171, -5.619, p  less then 0.001; I2 = 80.1%). Subgroup analysis revealed that effect of L-carnitine supplementation on liver enzymes was not significant in normal weight and healthy subjects. Baseline BMI and health status were the potential source of heterogeneity. CONCLUSION L-carnitine supplementation showed beneficial hepato-protective effects on circulating liver enzymes.
