Consequently, antioxidant enzymes such as catalase (CAT) superoxide dismutase (SOD) peroxidase (APX) and glutathione reductase (GR) activities were found to be significantly elevated in the desiccated state to avoid oxidative damage. Increased malondialdehyde (MDA) content and relative electrolyte leakage (REL) during desiccation provide evidence for membrane damage and loss of cell-wall integrity. During desiccation, the contents of osmolytes represented by sucrose and proline were found to increase to maintain cell structure integrity. After rehydration, all physiological, biochemical and morphological properties remain unchanged or slightly changed when compared to the hydrated state. Hence, we believe that these unique adaptations contribute to the remarkable desiccation-tolerance property of this plant.Phthalocyanine green nano pigment was prepared using supercritical gas antisolvent (GAS) process based on the SC-CO2 method. Thermodynamic models were developed to study the volume expansion and operating conditions of the GAS process. Peng-Robinson EoS were applied for binary (CO2 and DMSO) and ternary (CO2, DMSO, and pigment) systems. A Box-Behnken experimental design was used to optimize the process. Influences of temperature (308, 318 and 328 K), pressure (10, 15 and 20 MPa) and solute concentration (10, 40 and 70 mg/mL) were studied on the particles size and their morphology. The fine particles produced were characterized by SEM, DLS, XRD, FTIR and DSC. Experimental results showed a great reduction in size of pigment particles in comparison to the original particles. The mean particle sizes of nanoparticles were obtained to 27.1 nm after GAS based on SC-CO2 method.The unique properties of N-heterocyclic carbenes (NHCs) as an effective ligand for palladium catalytic centers have recently found much attention. In this work, Fe3O4 nanoparticle supported palladium(II)-N-heterocyclic carbene catalyst was successfully designed, synthesized and characterized by various methods. The activity of the catalyst was evaluated in the Mizoroki-Heck cross-coupling reaction in which the desired products were obtained in high yield in H2O as a green solvent. The reaction was carried out in short reaction times using low amounts of the catalyst.  https://www.selleckchem.com/products/sndx-5613.html  Moreover, the catalyst was easily separated from the reaction media and reused for 5 cycles.To analyze the epidemiological characteristics and drug resistance of tuberculosis (TB) patients in northern China. The epidemiological characteristics of 620 patients with tuberculosis from 2014 to 2016 were analyzed, including gender, age, occupation, education, income, place of residence and time distribution. 148 strains were identified as mycobacterium tuberculosis infection, 46 of 148 strains were identified as resistant strains, and among of which 73.91% of mono-resistance rate, 17.39% of poly-resistance rate, and 8.70% of multidrug resistant rate. Most of the patients were male, farmers, and the age of between 40 and 60, primary education background, income of 5000-10000RMB/year and newly diagnosed patients. The resistance rates of the four first line anti-tuberculosis drugs ranked as S (streptomycin)＞R (rifampicin)＞H (isoniazid)＞E (ethambutol). 12 drug resistance spectrums were found, among them, mono-resistance was mainly concentrated in S (45.65%), poly-resistance was mainly concentrated in H + S (8.70%), and multidrug resistance was mainly concentrated in H + R (4.35%). Therefore, middle-aged people, male, farmers, education for elementary or junior high school, and new patients with incomes not exceeding 10000RMB/year will be the key population for prevention and control in the future and the main drug-resistant population. This is particularly relevant for controlling infection sources, community prevention and control, and drug resistance treatment.Research involving human subjects requires strict adherence to ethical principles, including informed consent and assuring data confidentiality. Herein, a questionnaire was utilized to assess compliance of graduate students who conduct research involving human subjects in Jordan with proper practices related to informed consent and maintaining of data confidentiality. Among the 251 respondents, 55.4% were from health-related fields, 61.4% undertook research involving humans, and 48.6% did research requiring institutional review board approval. Only 37.1% of respondents reported exposure to research ethics education during their graduate study. Satisfactory adherence to informed consent practices was reported at rates of 56.0%-67.5%. Satisfactory adherence to practices related to data confidentiality and study participants' anonymity was reported at rates of 67.3%-74.7%. Sharing of data or samples with others was reported at a rate of 24.3%. The rates of adherence to proper informed consent practices and practices that maintain data confidentiality were less than ideal. Significant policy changes need to be implemented to address these issues.The aromatic nucleophilic substitution reactions of the nitro group of 4-Nitro-N-alkyl-1,8-naphthalimides by thiolate anions produce fluorescent derivatives and their rates are strongly accelerated by micelles of hexadecyltrimethylammonium chloride even at low pH. Acceleration factors of this reactions can reach million-fold. As the products are oxidant-insensible, this reaction allows the determination of SH- containing compounds such as cysteine, glutathione or proteins even in oxidative conditions. Limits of detection are as low as 5 × 10-7 M, ten times lower than the limit for the classic 5,5'-dithiobis-(2-nitrobenzoic) acid method. Moreover, this reaction can be developed at pHs between 6.5 and 7.5 thereby diminishing the rate of spontaneous oxidation of the thiols. In addition, we demonstrated that 4-Nitro-N-alkyl-1,8-naphthalimides can be used to evidence SH groups in peptides, proteins and living cells.The solvent diffusivity is considered as a key factor in the design of solvent assisted processes in the bitumen field. In this study, a novel Adaptive neuro-fuzzy interference system (ANFIS) is employed to evaluate the diffusivity of the light hydrocarbons in the bitumen system. The particle swarm optimization (PSO) and genetic algorithm (GA) are adopted to promote ANFIS efficiency. The proposed models are established by a prepared dataset from multiple papers in the literature. Temperature (T), pressure (P) and molecular weight of alkanes (Mw) were considered as the input variables and on the other hand, Statistical parameters and graphical methods were used to appraise ANFIS, ANFIS-PSO, and ANFIS-GA performance. The results demonstrated that the highest correlation coefficient is related to ANFIS-PSO with R2 = 0.991 and 0.987 for train and test data, respectively. In the end, the results indicated that the ANFIS-PSO model has a higher level of desirability based on statistical parameters.
