Selected HYCOs given orally to mice accelerated skin wound closure, reduced psoriasis-mediated inflammation and disease symptoms equalling or surpassing the effect of DMF, and ameliorated motor dysfunction in a mouse model of multiple sclerosis. Thus, HYCOs have potent anti-inflammatory activities that are recapitulated in disease models in which inflammation is a prominent component. Prolonged daily administration of HYCOs (up to 40 days) is well tolerated in animals. Our results clearly confirm that HYCOs possess a dual mode of action highlighting the notion that simultaneous Nrf2 targeting and CO delivery could be a clinically relevant application to combat inflammation. Investigation of components of the chloroform-soluble and ethyl acetate-soluble extracts of the aerial parts of Chromolaena odorata L. selected by PCSK9 mRNA expression monitoring assay in HepG2 cells led to the isolation of a new stilbene dimer, (+)-8b-epi-ampelopsin A (1), and 30 known compounds (2-31). The structures of the isolates were established by interpretation of NMR spectroscopic data and the stereochemistry of the new stilbene (1) was proposed based on ECD and NMR calculations. Among the isolates, 1, 5,6,7,4'-tetramethoxyflavanone (6), 5,6,7,3',4'-pentamethoxyflavanone (7), acacetin (18), and uridine (21) were found to inhibit PCSK9 mRNA expression with IC50 values of 20.6, 21.4, 31.7, 15.0, and 13.7 µM, respectively. Furthermore, the most abundant isolate among the selected compounds, 6, suppressed PCSK9 and low-density lipoprotein receptor protein expression in addition to downregulating the mRNA expression of HNF-1α. Eucalyptus camaldulensis Dehnh belongs to family Myrtaceae. They are massive in Egypt. Although reputed for high phenolic content, barks are considered waste. Ageing is a natural phenomenon caused by apoptosis and senescence resulting in wrinkles. The phytochemical analysis of the 70% ethanolic Eucalyptus camaldulensis bark extract (EBE) and evaluation of its anti-ageing potential and as silver nanoparticles (AgNPs) were conducted in this study. Ultra performance liquid chromatography / electrospray ionization mass spectrometry of EBE fingerprint revealed twenty compounds, where Rutin was major. EBE was standardized to contain 1.26 % Rutin. AgNPs synthesized by green synthesis, were characterized by transmission electron microscope and zeta potential measurement. Both EBE and AgNPs were subjected to MTT assay in HFB4 cells and cell cycle arrest. Flow cytometry was used to assess apoptosis and p16 INK4a. Genetic expression of p53 and p21 and telomerase level were determined. Anti-wrinkle enzyme assays were done. AgNps were spherical, 468.7 nm in size and with Poly dispersity index of 0.817 ± 0.129. EBE and AgNPs with IC50 0.156 mg/mL ± 0.05 and 2.315 ± 0.07 μg/mL expressed significant difference in % of cells (DNA content) at G2/M, apoptotic cells numbers, p53 and p21expression and p16INK4a vs aged cells (P less then 0.0001). Both expressed significant increase in telomerase (P less then 0.0001). They exhibited elastase, collagenase and tyrosinase inhibition (75 ± 4.3 and 75.9 ± 6.8 % at 300 μg/mL, 58 ± 4.8 and 63 ± 2.3, at 500 μg/mL, 51 ± 4.8 and 65 ± 5.87, at 500 μg/mL, respectively. Although it is considered waste, EBE and Ag NPs are anti-ageing candidates as they inhibit apoptosis, senescence and prevent wrinkles formation. BACKGROUND The clinical efficacy of curcumin has not yet been established for the treatment of cancer, despite a large body of evidence from numerous preclinical studies suggesting the therapeutic potential of curcumin, particularly in a synergistic combination with paclitaxel. The main obstacle in using curcumin for adjunctive cancer therapy is its low bioavailability via oral administration. PURPOSE We assessed the efficacy and safety of intravenous curcumin infusion in combination with paclitaxel in patients with metastatic and advanced breast cancer. STUDY DESIGN A randomized, double-blind, placebo-controlled, parallel-group comparative clinical study was conducted. METHODS A total of 150 women with advanced and metastatic breast cancer were randomly assigned to receive either paclitaxel (80 mg/m2) plus placebo or paclitaxel plus curcumin (CUC-1®, 300 mg solution, once per week) intravenously for 12 weeks with 3 months of follow-up. The primary outcome was determined based on the objective response rate ( performance was significantly higher with curcumin than the placebo during the treatment and at the end of the follow-up, suggesting better tolerance in the curcumin group. CONCLUSIONS Overall, treatment with curcumin in combination with paclitaxel was superior to the paclitaxel-placebo combination with respect to ORR and physical performance after 12 weeks of treatment. Intravenously administered curcumin caused no major safety issues and no reduction in quality of life, and it may be beneficial in reducing fatigue. ADVANCES IN KNOWLEDGE This is the first clinical study to explore the efficacy and safety of administering curcumin intravenously in combination with chemotherapy in the treatment of cancer patients. Bovine viral diarrhea virus (BVDV) infects different cell types including antigen-presenting cells such as macrophages. The infection induces pro-inflammatory cytokines like interleukin 1 beta (IL-1β), which is necessary to trigger a successful inflammatory response against infections. Several authors have reported differences between IL-1β gene expression and protein detection in BVDV-infected macrophages. These patterns may be related to inflammasome assembly, which promote the formation of active caspase 1 in order to produce mature IL-1β molecules. Our goal was to assess BVDV ability to induce the release of IL-β through a caspase 1 dependent pathway in bovine macrophages. We infected peripheral blood monocyte-derived macrophages using BVDV NADL strain at 0.001, 0.1, 2 and 10 multiplicities of infection (MOI) and we measured IL-1β at different times 2, 6, 12, 24, 48, 72 h. We found an increase of 1140-2154 pg for a MOI of 101 and 21 respectively. To inhibit caspase 1, we used either carbobenzoxy-valyl-alanyl-aspartyl-[O-methyl]- fluoromethylketone (Z-VAD) or carbobenzoxy-tyr-valyl-alanyl-aspartyl-[O-methyl]- fluoromethylketone (Y-VAD). We found decreased IL-1β secretion 2154 pg/ml to 854 pg/ml IL-1β secretion using Y-VAD and we observed decrease from 2154 pg/ml to 22.33 pg/ml with Z-VAD, and this inhibition was followed by diminished viral replication from 2.25 × 107 to 2.1 × 105 CCID50, which suggests that caspase 1-dependent secretion of the IL-1β active molecule is important for viral replication. This is the first report showing that BVDV infected-bovine macrophages trigger the caspase 1 dependent pathway for IL-1β activation and that activation increases viral replication. SCH772984 solubility dmso N-methyl-D-aspartate receptors (NMDARs) are crucial for excitatory synaptic transmission in the central nervous system. To study NMDARs more accurately and conveniently, we developed a stable NMDAR nanopore in a planar lipid bilayer. Pharmacological properties were validated using the allosteric modulator Ro 25-6981 and antagonist D-2-amino-5-phosphonopentanoic acid (D-APV). The cyanotoxin β-N-methylamino-L-alanine (BMAA) found in fresh water systems is suspected to be associated with the development of neurodegenerative diseases. Therefore, BMAA and its two isomers L-2, 4-Diaminobutyric acid dihydrochloride (DAB) and N-(2-aminoethyl) glycine (AEG) and an endogenous excitotoxin, quinolinic acid (QA), were studied using the NMDAR nanopores to assess their effects on NMDAR modulation. We demonstrated that the NMDAR nanopore could reliably detect its ligand molecules at the single-channel level. The study also demonstrated the practicability of NMDAR nanopores, and results were validated using two-electrode voltage-clamp (TEVC) recording. Compared with TEVC recording, the NMDAR nanopores conducted ion channel gating at the single-channel level without being affected by other proteins on the cell membrane. The highly sensitive and accurate NMDAR nanopore technique thus has a unique advantage in screening NMDAR ligand molecules that could be associated with neurodegenerative disease. Aesthetic wound healing is often experienced by patients after electrochemotherapy. We hypothesized that pulsed electric fields applied during electrochemotherapy (ECT) or gene electrotransfer (GET) protocols could stimulate proliferation and migration of human cutaneous cells, as described in protocols for electrostimulation of wound healing. We used videomicroscopy to monitor and quantify in real time primary human dermal fibroblast behavior when exposed in vitro to ECT and GET electric parameters, in terms of survival, proliferation and migration in a calibrated scratch wound assay. Distinct electric field intensities were applied to allow gradient in cell electropermeabilization while maintaining reversible permeabilization conditions, in order to mimic in vivo heterogeneous electric field distribution of complex tissues. Neither galvanotaxis nor statistical modification of fibroblast migration were observed in a calibrated scratch wound assay after application of ECT and GET parameters. The only effect on proliferation was observed under the strongest GET conditions, which drastically reduced the number of fibroblasts through induction of mitochondrial stress and apoptosis. Finally, we found that 24 h-conditioned cell culture medium by electrically stressed fibroblasts tended to increase the migration properties of cells that were not exposed to electric field. RT-qPCR array indicated that several growth factor transcripts were strongly modified after electroporation. Electrical stimulation (ES) has provided enhanced chondrogenesis of mesenchymal stem cells (MSCs) cultured in micro-mass without the addition of exogenous growth factors. In this study, we demonstrate for the first time that ES of MSCs encapsulated in an injectable hyaluronic acid (HA) - gelatin (GEL) mixture enhances the chondrogenic potential of the hydrogel. Samples were stimulated for 21 days with 10 mV/cm at 60 kHz, applied for 30 min every 6 h a day. Mechanical properties of hydrogels were higher if the precursors were dissolved in Calcium-Free Krebs Ringer Buffer (G' = 1141 ± 23 Pa) compared to those diluted in culture media (G' = 213 ± 19 Pa). Cells within stimulated hydrogels were rounder (55%) than non-stimulated cultures (32%) (p = 0.005). Chondrogenic markers such as SOX-9 and aggrecan were higher in stimulated hydrogels compared to controls. The ES demonstrated that normalized content of glycosaminoglycans and collagen to DNA was slightly higher in stimulated samples. Additionally, collagen type II normalized to total collagen was 2.43 times higher in stimulated hydrogels. These findings make ES a promising tool for enhancing articular cartilage tissue engineering outcomes by combining hydrogels and MSCs. OBJECTIVE To evaluate whether gestational age was associated with the severe maternal morbidity (SMM) of preterm cesarean delivery between 22 and 34 weeks of gestation (weeks). MATERIAL AND METHODS We performed an observational retrospective cohort study in two tertiary university hospitals in 2018. We included all mothers of preterm infants born by caesarean delivery between 22 and 34 weeks, excluding mothers with multiple births greater than two, with pregnancy terminations or stillbirths, and who died unrelated to obstetrical causes. The principal endpoint, SMM, was a composite outcome (classical uterine incision, postpartum hemorrhage defined by blood loss ≥ 500 mL, blood transfusion, any injury to adjacent organs, unplanned procedure/need for reintervention, Intensive Care Unit (ICU) stay longer than 24 hours, postpartum fever, and/or death). RESULTS Among the 252 women, SMM occurred in 89 (35.3%) cases. After multivariate analysis, gestational age was independently associated with SMM (adjusted Odds Ratio [aOR] 0.
