Sepsis is a potentially fatal illness that can lead to impairment of multiple organs such as liver. The condition is deeply associated with oxidative stress and inflammation. The aim of current study was to evaluate protective effects of MMF in sepsis-induced hepatic dysfunction. Wistar rats were assigned to one of sham, CLP, CLP + dexamethasone (as pos. control of inflammation) and CLP + MMF groups. Levels of serum IL-1β, IL-6, IL-10, AST, ALT and γ-GT were quantified. Furthermore, Hepatic levels of GSH and MDA and mRNA expression of TNF and NFKBIA along with hepatic protein level of TLR-4 were assessed. Septic rats demonstrated risen levels of IL-1β, IL-6, IL-10, AST, ALT and γ-GT, while treatment with dexamethasone or MMF attenuated these levels. Moreover, enhancements in protein level of TLR-4 and mRNA levels of TNF and NFKBIA were observed in CLP rats. These elevations were mitigated in CLP-induced rats that were treated with either dexamethasone or MMF. Treatment with dexamethasone or MMF also shifted sepsis-induced disturbance in the levels of GSH and MDA towards sham levels. Hepato-protective effects of dexamethasone and MMF were further confirmed by histopathol. observations. Our findings imply that MMF alleviates sepsis-induced hepatic dysfunction by mitigating the inflammatory and oxidative state and this effect is at least partly mediated by the inhibition of TLR-4/NF-κB signalling pathway.

The discovery of new edible flowers that are nontoxic, innocuous flowers having human health benefits, surveys of their phytochems. and utilization are of great scientific and com. interest. Dendrobium officinale and Dendrobium devonianum are precious Traditional Chinese Medicine. During the massive com. cultivation, a lot of flowers were produced and certified as edible flowers, and the phytochem. profiles and bioactivities warrant evaluate. The present study aimed to investigate the phytochems. and antioxidative activities in flowers of D. officinale (DOF) and D. devonianum (DDF). In total, 474 metabolites were identified using a widely targeted metabonomics method, 16 amino acids and 6 flavonoids were measured using high-performance liquid chromatog. (HPLC), and 8 fatty acids were detected using gas chromatog.-mass spectrometry (GC-MS). Both flowers contained various amino acids, including 7 essential amino acids, diverse flavonoids, especially quercetin, kaempferol and their derivatives, and high levels of Me linoleate and Me linolenate. The relative levels of quercetin, kaempferol and their glycosides were higher in DDF than in DOF, whereas the relative levels of several flavonoids C-glycosides were high in DOF. Ethanol extracts of both DOF and DDF showed antioxidative capacities including the scavenging of 1,1-diphenyl-2-picrylhydrazyl and hydroxyl radicals. Both edible flowers contained flavonoids, amino acids, and fatty acids and have antioxidative activities, which should be explored for use in functional foods and pharmaceuticals.

Chen, Sunhui; Qiu, Qiujun; Wang, Dongdong; She, Dejun; Yin, Bo; Gu, Guolong; Chai, Meihong; Heo, Dong Nyoung; He, Huining; Wang, Jianxin published the artcile< Dual-sensitive drug-loaded hydrogel system for local inhibition of post-surgical glioma recurrence>, Category: esters-buliding-blocks, the main research area is post surgical glioma recurrence drug loaded hydrogel local inhibition; Glioma recurrence; Magnetic resonance imaging; Reactive oxygen species-sensitive nanoparticles; Synergistic effect; Thermo-sensitive hydrogel.

Local treatment after resection to inhibit glioma recurrence is thought to able to meet the real medical needs. However, the only clin. approved local glioma treatment-wafer containing bis(2-chloroethyl) nitrosourea (BCNU) showed very limited effects. Herein, in order to inhibit tumor recurrence with prolonged and synergistic therapeutic effect of drugs after tumor resection, an in situ dual-sensitive hydrogel drug delivery system loaded with two synergistic chemo-drugs BCNU and temozolomide (TMZ) was developed. The thermosensitive hydrogel was loaded with reactive oxygen species (ROS)-sensitive poly (lactic-co-glycolic) acid nanoparticles (NPs) encapsulating both BCNU and TMZ and also free BCNU and TMZ. The in vitro synergistic effect of BCNU and TMZ and in vivo presence of ROS at the residual tumor site were confirmed. The prepared ROS-sensitive NPs and thermosensitive hydrogel, as well as the long-term release behavior of drugs and NPs, were fully characterized both in vitro and in vivo. After >90% glioblastoma resection, the dual-sensitive hydrogel drug delivery system was injected into the resection cavity. The median survival time of the exptl. group reached 65 days which was twice as long as the Resection only group, implying that this in situ drug delivery system effectively inhibited tumor recurrence. Overall, this study provides new ideas and strategies for the inhibition of postoperative glioma recurrence.

Yamijala, Sharma S. R. K. C.; Kwon, Hyuna; Guo, Juchen; Wong, Bryan M. published the artcile< Stability of Calcium Ion Battery Electrolytes: Predictions from Ab Initio Molecular Dynamics Simulations>, Electric Literature of 112-63-0, the main research area is calcium ion battery electrolyte ab initio mol dynamics simulation; Born−Oppenheimer molecular dynamics; ab initio molecular dynamics; calcium ion batteries; electrolyte stability; time-dependent PDOS.

Multivalent batteries, such as magnesium-ion, calcium-ion, and zinc-ion batteries, have attracted significant attention as next-generation electrochem. energy storage devices to complement conventional lithium-ion batteries (LIBs). Among them, calcium-ion batteries (CIBs) are the least explored due to difficult reversible Ca deposition-dissolution In this work, we examined the stability of four different Ca salts with weakly coordinating anions and three different solvents commonly employed in existing battery technologies to identify suitable candidates for CIBs. By employing Born-Oppenheimer mol. dynamics (BOMD) simulations on salt-Ca and solvent-Ca interfaces, we find that the tetraglyme solvent and carborane salt are promising candidates for CIBs. Due to the strong reducing nature of the calcium surface, the other salts and solvents readily decompose We explain the microscopic mechanisms of salt/solvent decomposition on the Ca surface using time-dependent projected d. of states, time-dependent charge-transfer plots, and climbing-image nudged elastic band calculations Collectively, this work presents the first mechanistic assessment of the dynamical stability of candidate salts and solvents on a Ca surface using BOMD simulations, and provides a predictive path toward designing stable electrolytes for CIBs.

The overexpression of EGFR correlates with rapidly progressive disease, resistance to chemotherapy and poor prognosis. In certain human cancers, PI3K works synergistically with EGFR to promote proliferation, survival, invasion and metastasis. Development of dual-target drugs against EGFR and PI3K has therapeutic advantage and was an attractive approach against tumors. In this work, based on the mol. docking and previous studies, a series of 4-aminoquinazolines derivatives containing 6-sulfonamide substituted pyridyl group were rationally designed and identified as potent EGFR and PI3K dual inhibitors. The cytotoxicity experiment results showed that this series of compounds could effectively inhibit cell growth. The kinase assay demonstrated that 6c and 6i had high inhibition for EGFR and selectivity for PI3Kα distinguished from other isoforms. Further experiments showed that 6c could induce cell cycle arrest in G1 phase and apoptosis in BT549 cells. The western blot assay indicated that 6c inhibited the proliferation of BT549 cell through EGFR and PI3Kα/Akt signaling pathway. Our study suggested that compound 6c was a potential dual inhibitors of EGFR and PI3Kα.

Ding, Sheng; Zhu, Jinxing; Tian, Saiqi published the artcile< Polyurethane-based retanning agents with antimicrobial properties>, Category: esters-buliding-blocks, the main research area is polyurethane retanning agent antimicrobial property.

Polyurethane-based retanning agents with antimicrobial properties were synthesized by the chem. incorporation of ciprofloxacin (CPFX) units into polyurethane chains. The chem. structures were characterized by Fourier transform IR (FTIR) and gel permeation chromatog. (GPC). Then, the retanning agents were applied in the leather retanning process. Owing to the conjugation of CPFX into polyurethane chains, the mol. weight increases, further leading to the decrease in hydroxyl value and increase in particle size. The shrinkage temperature was improved after retanning. Owing to the filling of retanning agents in the gap of collagen fibers, the average thickness of leather increased by 65.8%. The mech. properties of leather were visibly improved because of the large number of -COOH coordinate with Cr3+ and more hydrogen crosslinking with carboxyl group, amino group, and hydroxyl group of leather collagen. Furthermore, leather retanned by these polyurethane-based retanning agents presented good antimicrobial properties. The antibacterial activity could be conserved above 89% even after rinsing for ten times.

Takiyama, Mikina; Matsumoto, Takashi; Sanechika, Sho; Watanabe, Junko published the artcile< Pharmacokinetic study of traditional Japanese Kampo medicine shimotsuto used to treat gynecological diseases in rats>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is shimotsuto medicine gynecol disease pharmacokinetics; Active ingredients; Blood and circulatory system; Gynecological disease; Pharmacokinetics; Shimotsuto.

Shimotsuto is a traditional Japanese Kampo medicine used to treat gynecol. diseases, such as irregular menstruation, in addition to oversensitivity to cold and chilblains. Part of the pharmacol. actions of shimotsuto is traditionally considered to be exerted by an improvement effect of the blood and the circulatory system. Multiple ingredients (e.g., catalpol and paeoniflorin) contained in shimotsuto have been reported to have pharmacol. activities on the blood and circulatory system, and thus been considered to contribute to the pharmacol. actions of shimotsuto. However, it remains unclear whether the ingredients can be absorbed into the body following oral administration of shimotsuto. The aim in the present study was to specify shimotsuto ingredient absorbed into the systemic circulation in rats. Seven candidate active ingredients (catalpol, paeoniflorin, albiflorin, ligustilide, senkyunolide A, butylphthalide, and ferulic acid) in plasma after oral administration of shimotsuto were quantified by targeted liquid chromatog.-tandem mass spectrometry (LC-MS/MS) anal. This study also performed nontargeted LC-MS/MS anal. of plasma following administration of constituent crude drugs of shimotsuto to find extensively blood-absorbed ingredients of shimotsuto. Among detected peaks in the nontargeted anal., two peaks could be identified as bergapten and 8-debenzoylpaeoniflorin, subsequently their concentrations in shimotsuto-treated rat plasma were quantified. These pharmacokinetic studies indicated that catalpol showed the highest plasma concentration following administration of shimotsuto, followed by 8-debenzoylpaeoniflorin. This study suggests that all nine ingredients are absorbed into the blood following oral administration of shimotsuto and possibly contribute to its pharmacol. action.

Ampong, Isaac published the artcile< Metabolic and Metabolomics Insights into Dilated Cardiomyopathy>, Safety of (9Z,12Z)-Methyl octadeca-9,12-dienoate, the main research area is review metabolomics dilated cardiomyopathy population sex difference; Biomarkers; Dilated cardiomyopathy; Metabolites; Metabolomics.

A review. Metabolomics is an emerging and powerful discipline that provides a global information on the phenotype of mammalian systems via the study of endogenous and exogenous metabolites in cells, tissues, and biofluids. These studies aid in the identification of biomarkers to prevent diseases in later life or help to early detect onset of diseases as well as aiding in the elucidation of disease mechanisms. Metabolomics provides a unique opportunity to discover novel biomarkers for DCM. This review demonstrates evidence of metabolite-based biomarkers useful for predicting, diagnosing, and monitoring therapeutic interventions of DCM. Key metabolites identified as potential biomarkers for diagnosing DCM include acylcarnitines, succinic acid, malate, methylhistidine, aspartate, methionine, and phenylalanine. In terms of differentiating DCM from ischemic cardiomyopathy, potential biomarkers including 1-pyrroline-2-carboxylate, norvaline, lysophosphatidylinositol (16:0/0:0), phosphatidylglycerol, fatty acid esters of hydroxy fatty acid, and phosphatidylcholine were identified. Acylcarnitines, isoleucine and linoleic acid, and tryptophan were the main biomarkers to monitor treatment response to DCM. Mapping metabolites to metabolic pathways revealed dysregulation of branch-chain amino acid, glycolysis, tricarboxylic acid cycle, and triacylglycerol and pentose phosphate metabolism, which have the therapeutic potential for DCM. This review shows several limitations including the use of small sample sizes, lack of interpretation of age and sex differences in most studies, and the fact that studies have so far been limited to case-control study designs. Metabolites have close proximity to disease phenotype. With recent advances in metabolomics field, potential biomarkers for DCM have been identified based on studies using different biol. and metabolomics technologies. However, multicenter studies with larger populations that will lead to validation of these identified biomarkers to enable their clin. translation and utilization are still needed. Dilated cardiomyopathy (DCM) is the most common form of heart muscle disease characterized by progressive dilatation and ventricular dysfunction.
