Ethyl formate and phosphine fumigations on the two-spotted spider mite, Tetranychus urticae and their biochemical responses

Two spotted spider mite, Tetranychus urticae, is a polyphagous pest to a variety of plants and they are hard to be controlled due to occurrence of resistance to acaricides. In this study, biochemical evaluation after ethyl formate (EF) and phosphine (PH3) fumigation towards T. urticae might help officials to control them in quarantine purposes. PH3 fumigation controlled eggs (LC50; 0.158 mg/L), nymphs (LC50; 0.030 mg/L), and adults (LC50; 0.059 mg/L) of T. urticae, and EF effectively affected nymphs (LC50; 2.826 mg/L) rather than eggs (LC50; 6.797 mg/L) and adults (LC50; 5.836 mg/L). In a longer exposure time of 20 h, PH3 fumigation was 94.2-fold more effective tool for control of T. urticae than EF fumigant. EF and PH3 inhibited cytochrome c oxidase (COX) activity differently in both nymphs and adults of T. urticae. It confirmed COX is one of target sites of these fumigants in T. urticae and COX is involved in the respiratory chain as complex IV. Molecular approaches showed that EF fumigation completely down-regulated the expression of cox11 gene at the concentration of LC10 value, while PH3 up-regulated several genes greater than twofold in T. urticae nymphs treated with the concentration of LC50 value. These increased genes by PH3 fumigation are ndufv1, atpB, para, and ace, responsible for the expression of NADH dehydrogenase [ubiquinone] flavoprotein 1, ATP synthase, and acetylcholinesterase in insects, respectively. Lipidomic analyses exhibited a significant difference between two fumigants-exposed groups and the control, especially an ion with 815.46 m/z was analyzed less than twofold in the fumigants-treated group. It was identified as PI(15:1/18:3) and it may be used as a biomarker to EF and PH3 toxicity. These findings may contribute to set an effective control strategy on T. urticae by methyl bromide alternatives such as EF and PH3 because they have shared target sites on the respiratory chain in the pest.

Cytotoxicity Assessment and Apoptosis-related Gene Profiling of Antibody Treated Acute Myeloid Leukemia (AML) and Acute Lymphocytic Leukemia (ALL) Cancerous Cell Lines

Acute myeloid leukemia (AML) and acute lymphocytic leukemia (ALL) are common acute leukemia in adults and children, respectively. In these malignancies, chemotherapy is the main treatment strategy that fails in many cases and is usually associated with adverse effects on healthy cells. In this regard, the development of new therapies is essential. Monoclonal antibodies directed to the cell surface markers of leukemic blasts may have promising consequences with minimal toxic effects on normal cells. Since cluster of differentiation 45Ra (CD45Ra) and CD123 antigens, two considered surface markers of leukemic blasts in AlVIL and ALL respectively, are overexpressed on AML and ALL blasts, CD34(+) leukemic progenitors, and AML-LSCs in comparison with normal hematopoietic stem cells (HSCs), they were selected to be targeted; using specific monoclonal antibodies. In this project, CD45Ra(+) cells and CD123(+) cells were targeted by anti-CD45Ra and/or anti-CD123 monoclonal antibodies. Cytotoxicity effect and cell death induction was determined by 3-(4,5-dimethylthiazol-2-yl)-2-5-diphenyltetrazolium bromide (IVITT) assay and flow cytometry. Changes in the expression profile of MCL1, cMyc, Survivin, Id1, and PIM1 genes were assessed by real-time PCR. Statistical analysis of the results showed effective antibody-mediated cytotoxicity and induction of apoptosis in KG1 alpha (CD45Ra(+)) and Nalm6 (CD123(+)) cell lines. Also, a significant change in the expression level of some of the apoptosis-related genes was observed. According to the results of this study, it can be concluded that an effective targeting of AML and ALL cancerous cell lines can be performed by anti-CD45Ra and anti-CD123 monoclonal antibodies through their effector functions and apoptosis induction.

LncRNA XIST protects podocyte from high glucose-induced cell injury in diabetic nephropathy by sponging miR-30 and regulating AVEN expression

Diabetic nephropathy (DN) is one of the most important complications of diabetes mellitus. Thus, it is urgent to develop a novel diagnosis or therapeutic strategy that could suspend DN progression. Moreover, there is increasing evidence demonstrating that long non-coding RNA (lncRNA) acts as critical players in regulating autophagy and are involved in DN. We demonstrated that lncRNA X-inactive specific transcript (XIST) was downregulated in high glucose (HG) treated podocytes, accompanied by increased apoptosis of podocytes. Overexpression of XIST significantly reduced the apoptosis and promoted the number of viable cells of podocyte under HG treatment. Prediction by Targets can and dual-luciferase reporter assay revealed the interaction between miR-30 and XIST and AVEN. Further WB (Western Blot), MTT (3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide), and flow cytometry confirmed that XIST could reverse the expression of AVEN and ameliorate HG-induced apoptosis. In conclusion, our research revealed that XIST plays a protective effect on podocyte injury induced by HG through miR-30/AVEN axis.

But sometimes, even after several years of basic chemistry education, it is not easy to form a clear picture on how they govern reactivity! 109-64-8, you can contact me at any time and look forward to more communication. Name: 1,3-Dibromopropane.

Betulinic acid inhibits glioma cell viability by down-regulation of NF-kappa B and enhancement of apoptosis

Purpose: To determine the inhibitory potential of betulinic acid on pm-survival signaling pathway in glioblastoma. Methods: Changes in viabilities of glioma cells and primary astrocytes were measured using 3-(4, 5dimethylthiazol-2-yl)-2, 5-diphenyltetrazolium bromide (MTT) assay. Apoptotic changes were analyzed using Hoechst 33342 staining and Annexin V-FITC/PI kits. Western blotting was used for assaying the protein expressions of various pro-apoptotic and anti-apoptotic factors. Results: The proliferative potential of U87MG and A172 cells were significantly reduced on treatment with betulinic acid in a concentration- and time-dependent manner. Treatment with betulinic acid at a dose of 8.75 mu g/mL increased apoptosis in U87MG and A172 cells to 41.8 +/- 0.5 and 48.8 +/- 0.5%, respectively (p < 0.05). Betulinic acid significantly decreased intracellular levels of NF kappa B p65 and suppressed levels of survivin, XIAP and Bcl-2 in U87MG and A172 cells (p < 0.05). However, betulinic acid significantly increased the levels of Bax and activated caspase-9 and caspase-3 in U87MG and A172 cells (p < 0.05). Conclusion: Betulinic acid inhibited the proliferation of U87MG and A172 glioblastoma cells and mediated their apoptosis. There is need for in vivo studies for validation of the therapeutic potential of betulinic acid as an anti-glioblastoma drug. I hope this article can help some friends in scientific research. I am very proud of our efforts over the past few months and hope to 2067-33-6 help many people in the next few years. HPLC of Formula: C5H9BrO2.

Study on the characteristics of charging/discharging processes in three-phase energy storage coupling in solar air conditioning system

A new combination system of three-phase energy storage and solar absorption refrigeration has been developed in this paper. The operation process of LiBr-H2O three-phase energy storage system is described in detail. Thermodynamic analysis models of charging/discharging processes based on the absorption principle are established in order to understand the dynamic characteristics of three-phase energy storage and release processes. The dynamic simulations of charging/discharging processes are carried out by using MATLAB. The influences of operation parameters on the characteristic parameters of three-phase charging/discharging are analyzed, and the performance evaluation indexes of three-phase energy storage system are obtained. The simulation results showed that the lower initial concentration of LiBr-H2O solution, the smaller mass flow rate of LiBr-H2O sprayed on the heat exchanger in the energy storage tank and the higher heat conductance of the heat exchanger (KA) result in the higher energy storage efficiency and energy storage density. The smaller mass flow rates of LiBr-H2O and the cooling water can make the more stable discharging process with longer cooling time. The research results can provide theoretical guidance for further improving and optimizing the operation performance of three-phase energy storage system coupling in solar air conditioning.

Microbial reduction of bromate: current status and prospects

Bromate is a disinfection byproduct (DBP) that forms during the ozonation of bromide-containing natural water, which may cause health risks to humans. In this review, we provide an overview of the mechanism of bromate formation, microbial communities and bioreactors that are responsible for bromate reduction. Bromate can be formed through two pathways of bromide oxidation by ozone or by OH, and it can be removed by biological approaches. Members belonging to phyla of Spirochaetes, Proteobacteria, Firmicutes, Actinobacteria, Clostridium, Deinococcus-Thermus and Bacteroidetes have been identified as capable of reducing bromate to bromide. Multiple configurations of biofilm bioreactors have been employed to cultivate microbial communities to perform bromate removal. The rapid development of multiomics has and will continue to accelerate the elucidation of the mechanisms involved in bromate and other DBP conversions, as well as the interaction patterns among different bacterial subdivisions in the bioremoval of DBPs.

Dravet syndrome: Treatment options and management of prolonged seizures

Over time, with careful delineation of Dravet syndrome, we have gained experience in treatments most likely to lead to improvement in seizures, as well as those that should be avoided. Sodium valproate, clobazam, stiripentol, and topiramate are all medications that may lead to benefit, as well as the ketogenic diet. Bromides may be utilized in resistant cases. However, equally important are outlining prompt rescue treatment for prolonged seizures and avoidance of precipitants. Newer agents including cannabidiol and fenfluramine have been demonstrated to be of benefit in clinical trials. We propose an algorithm for management, but appreciate that the positioning of newer agents is yet to be established.

Salt and bile salt accelerate self-assembly behavior of poly(ethylene oxide)-block-poly(propylene oxide)-block-poly(ethylene oxide) probed by curcumin fluorescence

Understanding self-assembly aspects of block copolymers is of great importance due to their utility in a wide range of applications whether in chemistry, pharmacy, or medicine. In this work, properties of poly(ethylene oxide) -block- poly(propylene oxide) -block- poly(ethylene oxide) (F108) are studied in solution using fluorescence technique and curcumin as the molecular probe. Fluorescence of curcumin has been tracked in solutions of different concentrations of F108. The CMC (critical micellar concentration) and CMT (critical micellar temperature) have been found to be 23.2 mu M and 35 degrees C respectively. First time curcumin fluorescence-based method has been proven to be useful to estimate CMT. Furthermore, fluorescence quenching technique using hydrophobic cetyl pyridinium bromide and hydrophilic KI quenchers has established the position of curcumin is located near the hydrophobic pocket of Stern-layer of F108 micelle. New insight on effect of ionic strength and bile salt on the CMC and CMT values of F108 is evaluated through curcumin probing. CMC has decreased with the increase in the concentration of the three salts except for NaC. The effect has been arranged in decreasing order as follows: NaDC > NaCl > NaC. On the other hand, the effect of the three salts on the CMT of F108 has been found to be less remarkable, with a 1-fold decrease for NaCl and NaDC and almost no change for NaC.

Ivermectin induces autophagy-mediated cell death through the AKT/mTOR signaling pathway in glioma cells

Glioma is one of the most common types of primary brain tumors. Ivermectin (IVM), a broad-spectrum antiparasitic drug, has been identified as a novel anticancer agent due to its inhibitory effects on the proliferation of glioma cells in vitro and in vivo. However, the ability of IVM to induce autophagy and its role in glioma cell death remains unclear. The main objective of the present study was to explore autophagy induced by IVM in glioma U251 and C6 cells, and the deep underlying molecular mechanisms. In addition, we examined the effects of autophagy on apoptosis in glioma cells. In the present study, transmission electronmicroscopy (TEM), immunofluorescence, Western blot and immunohistochemistry were used to evaluate autophagy activated by IVM. Cell viability was measured by 3-(4,5-dimethylthiazol2-yl)-2, 5-diphenyltetrazolium bromide (MTT) and colony formation assay. The apoptosis rate was detected by flow cytometry and terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL). Meanwhile, autophagy inhibition was achieved by using chloroquine (CQ). U251-derived xenografts were established for examination of IVM-induced autophagy on glioma in vivo. Taken together, the results of the present study showed that autophagy induced by IVM has a protective effect on cell apoptosis in vitro and in vivo. Mechanistically, IVM induced autophagy through AKT/mTOR signaling and induced energy impairment. Our findings show that IVM is a promising anticancer agent and may be a potential effective treatment for glioma cancers.

Innovative Turbine Intake Air Cooling Systems and Their Rational Designing

The efficiency of cooling ambient air at the inlet of gas turbines in temperate climatic conditions was analyzed and reserves for its enhancing through deep cooling were revealed. A method of logical analysis of the actual operation efficiency of turbine intake air cooling systems in real varying environment, supplemented by the simplest numerical simulation was used to synthesize new solutions. As a result, a novel trend in engine intake air cooling to 7 or 10 degrees C in temperate climatic conditions by two-stage cooling in chillers of combined type, providing an annual fuel saving of practically 50%, surpasses its value gained due to traditional air cooling to about 15 degrees C in absorption lithium-bromide chiller of a simple cycle, and is proposed. On analyzing the actual efficiency of turbine intake air cooling system, the current changes in thermal loads on the system in response to varying ambient air parameters were taken into account and annual fuel reduction was considered to be a primary criterion, as an example. The improved methodology of the engine intake air cooling system designing based on the annual effect due to cooling was developed. It involves determining the optimal value of cooling capacity, providing the minimum system sizes at maximum rate of annual effect increment, and its rational value, providing a close to maximum annual effect without system oversizing at the second maximum rate of annual effect increment within the range beyond the first maximum rate. The rational value of design cooling capacity provides practically the maximum annual fuel saving but with the sizes of cooling systems reduced by 15 to 20% due to the correspondingly reduced design cooling capacity of the systems as compared with their values defined by traditional designing focused to cover current peaked short-term thermal loads. The optimal value of cooling capacity providing the minimum sizes of cooling system is very reasonable for applying the energy saving technologies, for instance, based on the thermal storage with accumulating excessive (not consumed) cooling capacities at lowered current thermal loads to cover the peak loads. The application of developed methodology enables revealing the thermal potential for enhancing the efficiency of any combustion engine (gas turbines and engines, internal combustion engines, etc.).
