Trinuclear copper(ii) bromide complex [C3H5N3Br](2n)[Cu3Br8](n). Structure, magnetic properties and DFT calculations

Halidocuprates(ii) show unusual magnetic properties and a high degree of structural flexibility. We present the results of crystallographic, electron paramagnetic resonance (EPR) spectroscopic and magnetochemical analyses of a new [HL](2n)[Cu3Br8](n) compound (HL = 3-amino-4-bromopyrazolium) – the first example of an inorganic polymer built from trimeric [Cu3Br8](2-) units with a 5-membered nitrogen-containing heterocycle as an organic counter ion. The EPR spectrum of the polycrystalline sample exhibited a signal at g approximately equal to 2.06 broadened owing to spin-spin interactions between copper ions. The EPR and magnetochemical data indicate a ferromagnetic intertrimer interaction with Theta = 13 K and an antiferromagnetic intratrimer interaction with J = 310 K between the nearest-neighbor copper(ii) ions, which is in agreement with DFT calculations.

Chitosan Hydrogel Supports Integrity of Ovarian Follicles during In Vitro Culture: A Preliminary of A Novel Biomaterial for Three Dimensional Culture of Ovarian Follicles

Objective: Testing novel biomaterials for the three dimensional (3D) culture of ovarian follicles may ultimately lead to a culture model which can support the integrity of follicles during in vitro culture (IVC). The present study reports the first application of a chitosan (CS) hydrogel in culturing mouse preantral follicles. Materials and Methods: In this interventional experiment study, CS hydrogels with the concentrations of 0.5, 1, and 1.5% were first tested for fourier transform infrared spectroscopy (FT-IR), Compressive Strength, viscosity, degradation, swelling ratio, 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) cytotoxicity and live/dead assay. Thereafter, mouse ovarian follicles were encapsulated in optimum concentration of CS (1%) and compared with those in alginate hydrogel. The follicular morphology, quality of matured oocyte and steroid secretion in both CS and alginate were assessed by enzyme-linked immunosorbent assay (ELISA). The expression of folliculogenesis, endocrine, and apoptotic related genes was also evaluated by quantitative real-time polymerase chain reaction (qRT-PCR) and compared with day that in 0. Results: The rates of survival, and diameter of the follicles, secretion of estradiol, normal appearance of meiotic spindle and chromosome alignment were all higher in CS group compared with those in alginate group (P <= 0.05). The expression of Cyp19a1 and Lhcgr in CS group was significantly higher than that of the alginate group (P <= 0.05). Conclusion: The results showed that CS is a permissive hydrogel and has a beneficial effect on encapsulation of ovarian follicle and its further development during 3D culture.

Development of adaptive neuro-fuzzy inference system model for predict trihalomethane formation potential in distribution network simulation test

Trihalomethanes (THMs), which is one of the major classes of DBP known to be highly cytotoxic and genotoxic, were formed and modeled under controlled conditions by laboratory-scale distribution network simulation test. The formation potentials of THM depending on the parameters such as natural organic matter, bromide, chlorine, pH, and contact time were determined. Subsequently, the Adaptive Neuro-Fuzzy Inference System (ANFIS) model was developed using these parameters as inputs and THM formation potentials as output, and the correlation coefficient was 0.9817. In the range of the inputs, the ANFIS model representing the simulation test results were compared with THM formations of an actual distribution network system in dry and wet seasons. As a result, the predictions of the ANFIS model were little affected by the unidentified factors that were not used in model training but are known to affect THM formations in real waters and gave more consistent results than the EPA model.

Evaluation of 3 (4, 5 dimethyl-2-thiazolyl)-2, 5 diphenyl tetrazolium bromide method for rapid detection of vancomycin-resistant enterococci

Vancomycin-resistant enterococci (VRE) have become a global problem of hospital-associated infections. A rapid VRE detection and early isolation of the positive cases are essential for prevention and control of their transmission in hospitals. The aim of this study was to develop and evaluate a simple and rapid method for detection of VRE by using 3 (4, 5 dimethyl-2-thiazolyl)-2, 5 diphenyl tetrazolium bromide (MTT) colorimetric method compared with standard broth microdilution (BMD) and Epsilometer test (Etest). A total of 85 Enterococcus isolates (75 vancomycinnon-susceptible, 2 vancomycin-intermediate and 8 vancomycin-susceptible) were studied. The minimum inhibitory concentrations (MICs) of vancomycin for all isolates were tested by BMD, MTT and Etest methods. The MTT method gave results within 9 h with good category agreement, essential agreement, very major, major, and minor errors (100, 92.9, 0, 0 and 7.1%, respectively), which were comparable to those of the Etest (97.6, 95.3, 2.4, 0 and 4.7%, respectively). The Cohen’s kappa coefficient (kappa) of the MTT method compared with the BMD showed perfect agreement (1.000) (p < 0.001). The MTT method is simple and rapid for early VRE detection to support prevention and control the spread of the enterococci in hospitals.

Design of process for stabilization of La2NiMnO6 nanorods and their magnetic properties

In the present study, we have developed a process to stabilize La2NiMnO6 (LNMO) nanorods via hydrothermal process using cetyl trimethylammonium bromide as a capping agent. One dimensional morphology (nanorods) of LNMO leads to MnO6 octahedral expansion that contributed to the overall expansion in LNMO unit cell. Large shape anisotropy of nanorods carries structural (unit cell) modification in the form of horizontal and vertical tilt of NiO(6 )and MnO6 octahedra along the c axis. Large saturation magnetization M-s is observed for LNMO nanorods as compared to that of their bulk and nanoparticles. X-ray photoelectron spectroscopy (XPS) analysis confirmed the large M-s values observed for nanorods could be attributed to mixed valence states of magnetic ions at B-site (Mn3+, Mn4+, Ni2+, Ni3+). The optical studies of LNMO nanorods shows that the observed band gap (E-g: 1.9 eV) is considerably larger than band gap reported for bulk LMNO (E-g: 1.2-1.4 eV). The enhanced saturation magnetization of nanorods is consistent with a structurally ordered single phase material with very few antisite defects.

Key Takeaways Surface water was sampled upstream and downstream of several facilities to assess the bromide contributions from municipal and industrial wastewater discharges. Bromide was discharged from a coal-fired steam station and from at least one municipal wastewater treatment plant in each of the three watersheds evaluated. Sources of bromide vary among different watersheds and are not limited by industry.

Development of a nickel oxide/oxyhydroxide-modified printed carbon electrode as an all solid-state sensor for potentiometric phosphate detection

Phosphate is one of the main nutrients playing many key roles in the human body and plant growth. Because of this essential demand, phosphate is often used as a micronutrient additive in both fertilizers and dietary supplements. However, its excessive amount could result in severe health issues in the human body and the ecosystem of aquatic life. Therefore, there is a need for an inexpensive rapid measurement approach that could assess the optimum level of phosphate by using simple low-cost sensors. Here, for the first time, we demonstrate the use of a nickel oxide modified screen printed carbon (PrC) electrode as a low-cost electrochemical potentiometric phosphate detection sensor. The nickel oxide/oxyhydroxide (NiO/NiOOH)-PrC electrode has been prepared by a facile anodic electrodeposition process onto a screen printed carbon electrode. The characterization performed by field emission scanning electron microscopy (FE-SEM) and energy diffractive X-ray spectroscopy (EDS) techniques confirmed the formation of NiO/NiOOH by significant changes in surface morphology and elemental composition of PrC after electrodeposition. The results exhibited a porous deposited layer containing nickel and an increased oxygen value of the modified electrode as compared to pristine PrC. Potentiometric phosphate detection on the NiO/NiOOH-PrC electrode showed a linear response in the concentration range of 10(-6)-10(-1) M, yielding a slope of -78.48 mV per decade with a fast response time. The electrode demonstrated a stable response with less than 0.8% variability of the recorded potential over 2000 seconds. High durability and reusability of the electrode were confirmed by repeated potentiometric phosphate determination tests over a course of 21 days. Interference tests with chloride, nitrate, sulfate, bromide, acetate, and carbonate solutions revealed very low selectivity coefficients within the range of 10(-11)-10(-2), which indicated a high phosphate-selectivity of the developed sensor. This novel technology provides great potential for future scalable production and applications in portable real-time monitoring of phosphate ions in different precision agricultural and point-of-care diagnostic applications.

The proportionality constant is the rate constant for the particular unimolecular reaction. the reaction rate is directly proportional to the concentration of the reactant. I hope my blog about 29823-18-5 is helpful to your research. Computed Properties of C9H17BrO2.

A novel nanoliposomal formulation of the FDA approved drug Halofantrine causes cell death of Leishmania donovani promastigotes in vitro

Leishmaniasis is a notorious disease affecting mainly poor people. Visceral Leishmaniasis (VL) is a clinical form of Leishmaniasis which mainly affects people living below poverty line. There are no available vaccines against VL and chemotherapy still remains the mainstay for treatment. However, the use of the current therapeutic agents are limited due to issues of toxicity, side effects and cost effectiveness. Thus, repositioning of FDA approved drugs for anti-leishmanial therapeutics and encapsulation of the same in nanoliposomes may pave the way of future anti-leishmanial therapeutics. In this work, liposome encapsulated Halofantrine (Halolipo) was prepared by extrusion of hydrated lipid film method. The Halolipo was characterized by Dynamic Light Scattering and Transmission Electron Microscopy. The effect of Halolipo on Leishmania donovani Ag83 promastigotes was assessed by MIT assay and qualitative analysis of ROS generation and mitochondrial membrane depolarization was performed. The cell death was visualized by dual staining with Acridine orange and Ethidium bromide followed by fluorescence microscopy. The encapsulation of Halofantrine drug in liposome was confirmed by characteristic peak at 260 nm by UV-vis spectrophotometer. The formulated halolipo was 20 nm in size and stable for > 4 weeks at 4 degrees C. Maximum encapsulation was observed at a ratio of 1:200 (Lipid:Halofantrine) Halofantrine is released from Halolipo at both pH 7.2 and 5.5. Halolipo causes decrease in cell viability of L. donovani Ag83 promastigotes and leading to cellular stress as evident from increased ROS generation and mitochondrial membrane depolarization. These events culminate into cell death as observed by dual staining of L. donovani promastigotes by Acridine orange and Ethidium bromide. The novel Halolipo is a promising anti-leishmanial agent and may be used for future anti-leishmanial therapeutics.

Modular and regioselective synthesis of all-carbon tetrasubstituted olefins enabled by an alkenyl Catellani reaction

All-carbon tetrasubstituted olefins have been found in numerous biologically important compounds and organic materials. However, regio- and stereocontrolled construction of this structural motif still constitutes a significant synthetic challenge. Here, we show that a modular and regioselective synthesis of all-carbon tetrasubstituted olefins can be realized via alkenyl halide- or triflate-mediated palladium/norbornene catalysis, which is enabled by a modified norbornene containing a C2 amide moiety. This new norbornene co-catalyst effectively suppressed undesired cyclopropanation pathways, which have previously been a main obstacle for developing such reactions. Diverse cyclic and acyclic alkenyl bromides or triflates with a wide range of functional groups can be employed as substrates. Various substituents can be introduced at the alkene C1 and C2 positions regioselectively simply by changing the coupling partners. Initial mechanistic studies provide insights on the rate-limiting step as well as the structure of the actual active ligand in this system.

MicroRNA-760 acts as a tumor suppressor in gastric cancer development via inhibiting G-protein-coupled receptor kinase interacting protein-1 transcription

BACKGROUND Gastric cancer (GC) has become a serious threat to people’s health. Accumulative evidence reveals that dysregulation of numerous microRNAs (miRNAs) has been found during malignant formation. So far, the role of microRNA-760 (miR-760) in the development of GC is largely unknown. AIM To measure the expression level of miR-760 in GC and investigate its role in gastric tumorigenesis. METHODS Real-time quantitative polymerase chain reaction and Western blot analysis were used to measure the expression of miR-760 and G-protein-coupled receptor kinase interacting protein-1 (GIT1). Cell growth was detected by 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl-2-H-tetrazolium bromide (MTT) and cell colony formation assays. Apoptosis was assessed by flow cytometric analysis. The relationship between miR-760 and GIT1 was verified by luciferase reporter assay. RESULTS The results showed that the expression of miR-760 was decreased in GC and associated with poor clinical outcomes in GC patients. Furthermore, miR-760 restrained cell proliferation and cell colony formation and induced apoptosis in GC cells. In addition, miR-760 directly targeted GIT1 and negatively regulated its expression in GC. GIT1 was upregulated in GC and predicted a worse prognosis in GC patients. We also found that upregulation of GIT1 weakened the inhibitory effect of miR-760 in GC. CONCLUSION In conclusion, miR-760 targets GIT1 to inhibit cell growth and promote apoptosis in GC cells. Our data demonstrate that miR-760 may be a potential target for the treatment of GC.
