Abstract

Background Polycystic ovary syndrome is a complex disease related to the endocrine and metabolism. Its specific cause and pathogenesis have not been clear. Nesfatin-1 could not only regulate energy balance and glucose metabolism, but also affect the reproductive system. The Wnt/β-catenin signaling pathway affects follicle development, ovulation, corpus luteum formation, and steroid hormone production. Results Here, we studied the roles of nesfatin-1 and Wnt/β-catenin signaling pathway in the pathogenesis of polycystic ovary syndrome. Firstly, the human primary ovarian granulosa cells in vitro was cultured. The results showed that the apoptosis rate of ovarian granulosa cells in polycystic ovary syndrome patients was significantly higher than that of granular cells in normal people. Moreover, nesfatin-1 and Wnt/β-catenin pathway inhibitor IWR-1could inhibit the expressions of ovarian granulosa cells apoptosis genes and promote their proliferation, as well as nesfatin-1 affected the expressions of foxo3a and its downstream factors. Then, an in vitro culture system for ovarian granulosa cells (OGCs) was established by employing a rat model. The results are the same with those mentioned above. Conclusion This strongly proves that the nesfatin-1 participates in regulating the apoptosis and proliferation of granulosa cells by the Wnt/β-catenin pathway. According to the role of nesfatin-1 and IWR in polycystic ovary syndrome, nesfatin-1 and Wnt/β-catenin pathway can provide a guideline for the diagnosis and treatment of Polycystic ovary syndrome (PCOS).

Abstract

Enhanced safety, with the ability to control detonation behavior, while maintaining energy output are highly desirable characteristics for new high explosive (HE) materials. The use of switchable explosive spin crossover (ExSCO) compounds is a potentially powerful strategy to access on-demand mechanical sensitivity. Spin crossover is a transition between the low spin (LS) and high spin (HS) state electron configurations in a metal complex. We present our variable temperature impact sensitivity results on [Fe(Htrz)3]n[ClO4]2n, a high nitrogen Fe(II) ExSCO compound, and compare its mechanical sensitivity in the LS vs HS states. In addition, we describe the synthesis and properties of energetic acrylate monomers that will be used to develop custom materials for use in the additive manufacturing of explosives.

Abstract

Objectives Systemic diseases or oral situation changes can result in oral infections like candidiasis. Mouthwash is the most prevalent method to prevent or cure these infections. To formulate a more effective mouthwash, we combined Clotrimazole with a low dose of Chlorhexidine to investigate the in vitro effect against Candida spp.Methods and Materials Combinations of Chlorhexidine (0.03-16ug/ml) and Clotrimazole (0.03-16ug/ml) were tested against Candida spp. by microdilution chequerboard technique and disk diffusion method.Results From the chequerboard combination assay, the MICs of Chlorhexidine and Clotrimazole against Candida spp. decreased from >16µg/ml to 2–1µg/ml and from 2-0.25µg/ml to 0.5–0.125µg/ml, respectively, demonstrating favorable synergistic effects against 21 (84%) strains of Candida spp. The disk diffusion method showed an increase in halo size for the combination group when compared to the Clotrimazole alone group.Conclusions Studies have shown that combinations of antiseptic and antifungal agents are effective in nature. In our study, we found that low concentrations of Chlorhexidine can enhance the antifungal effect of Clotrimazole against Candida spp.. We predict that the mechanism of this synergism could be due to the increased penetration of Clotrimazole brought about by the binding of Chlorhexidine to the cell membrane. Further studies to determine the mechanism and in vivo effects could increase its probable usage in clinical studies.

Abstract

We report a critical re-evaluation of the synthesis and characterization of Cu8(MPP)4. This product was reportedly formed by the reaction of Cu(NO3)2 with 2-mercapto-5-n-propylpyrimidine (HMPP) and NaBH4, in ethanol, in the presence of [N(C8H17)4][Br]. In our hands, we found no experimental evidence to support the existence of Cu8(MPP)4 in the reaction mixture. Instead, we demonstrate that the material isolated from this reaction is a complex mixture containing [N(C8H17)4]+, Br–, NO3–, and 2-mercapto-5-n-propyl-1,6-dihydropyrimidine (H2MPP*), along with the Cu(I) coordination polymer, [Cu(MPP)]n. To support our conclusions, we have independently synthesized H2MPP* and [Cu(MPP)]n, as well as the related Cu(I) coordination complexes, [Cu(HMPP*)]n and [Cu2(MPP*)]n. All new materials were characterized by NMR spectroscopy and mass spectrometry, while H2MPP*, [Cu(HMPP*)]n (n = 4), and [Cu(MPP)]n (n = 6) were also characterized by X-ray crystallography.

Abstract

The group 11 hydride clusters [Ag6H4(dppm)4(OAc)2] (1) and [Cu3H(dppm)3(OAc)2] (2) (dppm = 1,1-bis(diphenylphosphino)methane) were synthesized in moderate yields from the reaction of M(OAc) (M = Ag, Cu) with Ph2SiH2, in the presence of dppm. Complex 1 is the first structurally characterized homometallic polyhydrido silver cluster to be isolated. Both 1 and 2 catalyze the hydrosilylation of (α,β-unsaturated) ketones. Notably, this represents the first example of hydrosilylation with an authentic silver hydride complex.

Abstract

The copper hydride nanocluster (NC) [Cu29Cl4H22(Ph2phen)12]Cl (2; Ph2phen = 4,7-diphenyl-1,10-phenanthroline) was isolated cleanly, and in good yields, by controlled growth from the smaller NC, [Cu25H22(PPh3)12]Cl (1), in the presence of Ph2phen and a chloride source at room temperature. Complex 2 was fully characterized by single-crystal X-ray diffraction, XANES, and XPS, and represents a rare example of an N* = 2 superatom. Its formation from 1 demonstrates that atomically precise copper clusters can be used as templates to generate larger NCs that retain the fundamental electronic and bonding properties of the original cluster. A time-resolved kinetic evaluation of the formation of 2 reveals that the mechanism of cluster growth is initiated by rapid ligand exchange. The slower extrusion of CuCl monomer, its transport, and subsequent capture by intact clusters resemble elementary steps in the reactant-assisted Ostwald ripening of metal nanoparticles.

Abstract

Apatite may be a common accessory mineral in coal seams, but interpretation of its origins can vary from syndepositional mineral detritus, early precipitation during diagenesis, and post coalification precipitation and replacement from hydrothermal or other fluids. It is hypothesised that paragenesis is reflected in the modes of occurrence in different stratigraphic units of the Late Permian in the Bowen Basin. From samples analysed in this study, apatite in the youngest unit, the Rangal Coal Measures, most commonly occurs as pore-apatites (i.e. apatites infilling preserved plant cell cavities of fusinite and semifusinite macerals and commonly associated with kaolinite) and less commonly as fracture-apatites (i.e. apatites infilling micro-fractures) and detrital-apatites intermixed with the organic coal layers (Detrital-B). In the tuffaceous Fort Cooper Coal Measures and equivalents, apatite occurs more commonly as detrital-apatites intermixed with the lithic layers (Detrital-A) (Detrital. Within the basal unit, the Moranbah Coal Measures and its equivalents, the mode is commonly encrusting-apatites (i.e. small apatite crystallites encrusting silicate minerals). Almost all apatites in the coal samples tested by electron microprobe microanalysis (EPMA), regardless of stratigraphic location and mode, are fluorapatite. Although there are some locality-driven enrichments, the minor and trace-element chemistry vary more so by mode of occurrence. For comparison, apatites from dykes intersecting the coal measures and from tuffs were also added to the study. These had lower fluorine (F) but measurable chlorine (Cl) contents and are enriched in light rare earth elements (LREE), similar to the Durango apatite that is of magmatic origins. Most of the detrital-A apatites are also enriched in LREE similar to the tuff-apatites, but with variable enrichment in the rare earth and yttrium elements. Detrital-B apatites have minimal Cl but also show the magmatic LREE trend. The pore- and fracture-apatites exhibited two trends. In the samples from tuffaceous coals (e.g., Fort Cooper Coal Measures), the pore- and fracture apatites tended to follow the magmatic LREE trend. In the Rangal Coal Measures, the pore- and fracture-apatites have elevated F contents, minimal Cl contents and depleted LREE contents (or Middle REE enrichment). Depletion of LREE could occur through leaching in an acidic environment, which is suggested by the abundance of kaolinite. Apatite precipitates under more neutral conditions although pore-apatites are commonly considered “early” and fracture-apatites “late” or post coalification. Their geochemical similarity suggests they have similar fluid origins and/or timing, with geothermal fluids moving through the porosity afforded by the structured inertinite group macerals and fractures. Verification of that geothermal source still requires further work and a technique that can analyse the isotopic composition—e.g., carbon (13C/12C), oxygen (18O/16O) and strontium (87Sr/86Sr)—of micron-sized crystals in situ.

Abstract

Atomically precise copper nanoclusters (NCs) are of immense interest for a variety of applications, but have remained elusive. Herein, we report the isolation of a copper NC, [Cu25H22(PPh3)12]Cl (1), from the reaction of Cu(OAc) and CuCl with Ph2SiH2, in the presence of PPh3. Complex 1 has been fully characterized, including analysis by X-ray crystallography, XANES, and XPS. In the solid state, complex 1 is constructed around a Cu13 centered-icosahedron and formally features partial Cu(0) character. XANES of 1 reveals a Cu K-edge at 8979.6 eV, intermediate between the edge energies of Cu(0) and Cu(I), confirming our oxidation state assignment. This assignment is further corroborated by determination of the Auger parameter for 1, which also falls between those recorded for Cu(0) and Cu(I).

Abstract

The introduction of inorganic components into a polymer matrix to form polymer composites is an emerging and promising approach to dielectric materials for capacitive energy storage. Ferroelectric polymers are particularly attractive as matrices for dielectric polymer composites owing to their highest dielectric constant (≥10) among the known polymers. Here, the important aspects and recent advances in the development of the ferroelectric-polymer-based dielectric polymer composites for high-energy-density capacitor applications are summarized. The preparation methods of ferroelectric-polymer composites with 0D, 1D, and 2D nanostructured fillers, surface-modified nanofillers, and hierarchically structured fillers, and their comprehensive impacts on the dielectric properties, breakdown strength, and energy density of the resulting composites are described. The most recent progress on the incorporation of multiple nanofillers with complementary functionalities into ferroelectric polymers and the design of layer-structured ferroelectric-polymer composites is also highlighted. A discussion of the scientific and technological issues that remain to be addressed and an outlook for the future of ferroelectric polymer-based dielectric composites are also presented.

Abstract

Differences in the behaviour of matter and antimatter have been observed in $K$ and $B$ meson decays, but not yet in any baryon decay. Such differences are associated with the non-invariance of fundamental interactions under the combined charge-conjugation and parity transformations, known as $C\!P$ violation. Using data from the LHCb experiment at the Large Hadron Collider, a search is made for $C\!P$-violating asymmetries in the decay angle distributions of $\Lambda^0_b$ baryons decaying to $p\pi^-\pi^+\pi^-$ and $p\pi^-K^+K^-$ final states. These four-body hadronic decays are a promising place to search for sources of $C\!P$ violation both within and beyond the Standard Model of particle physics. We find evidence for $C\!P$ violation in $\Lambda^0_b$ to $p\pi^-\pi^+\pi^-$ decays with a statistical significance corresponding to 3.3 standard deviations including systematic uncertainties. This represents the first evidence for $C\!P$ violation in the baryon sector., Comment: All figures and tables, along with any supplementary material and additional information, are available at https://lhcbproject.web.cern.ch/lhcbproject/Publications/LHCbProjectPublic/LHCb-PAPER-2016-030.html

Abstract

The copper hydride clusters [Cu14 H12 (phen)6(PPh3)4][X]2 (X=Cl or OTf; OTf=trifluoromethanesulfonate, phen=1,10-phenanthroline) are obtained in good yields by the reaction of [(Ph3P)CuH]6 with phen, in the presence of a halide or pseudohalide source. The complex [Cu14H12 (phen)6(PPh3)4][Cl]2 reacts with CO2 in CH2Cl2 , in the presence of excess Ph3 P, to form the formate complex [(Ph3P)2Cu(κ(2)-O2CH)], along with [(phen)(Ph3 P)CuCl].

Abstract

Two synthetic strategies for incorporating diiron analogues of [FeFe]-hydrogenases into short peptides via phosphine functional groups are described. First, utilizing the amine side chain of lysine as an anchor, phosphine carboxylic acids can be coupled via amide formation to resin-bound peptides. Second, artificial, phosphine-containing amino acids can be directly incorporated into peptides via solution phase peptide synthesis. The second approach is demonstrated using three amino acids each with a different phosphine substituent (diphenyl, diisopropyl, and diethyl phosphine). In total, five distinct monophosphine-substituted, diiron model complexes were prepared by reaction of the phosphine-peptides with diiron hexacarbonyl precursors, either (μ-pdt)Fe2(CO)6 or (μ-bdt)Fe2(CO)6 (pdt = propane-1,3-dithiolate, bdt = benzene-1,2-dithiolate). Formation of the complexes was confirmed by UV/Vis, FTIR and (31)P NMR spectroscopy. Electrocatalysis by these complexes is reported in the presence of acetic acid in mixed aqueous-organic solutions. Addition of water results in enhancement of the catalytic rates.

Abstract

Lithium enolates derived from carboxylic acids are ubiquitous intermediates in organic synthesis. Asymmetric transformations with these intermediates, a central goal of organic synthesis, are typically carried out with covalently attached chiral auxiliaries. An alternative approach is to utilize chiral reagents that form discrete, well-defined aggregates with lithium enolates, providing a chiral environment conducive of asymmetric bond formation. These reagents effectively act as noncovalent, or traceless, chiral auxiliaries. Lithium amides are an obvious choice for such reagents as they are known to form mixed aggregates with lithium enolates. We demonstrate here that mixed aggregates can effect highly enantioselective transformations of lithium enolates in several classes of reactions, most notably in transformations forming tetrasubstituted and quaternary carbon centers. Easy recovery of the chiral reagent by aqueous extraction is another practical advantage of this one-step protocol. Crystallographic, spectroscopic, and computational studies of the central reactive aggregate, which provide insight into the origins of selectivity, are also reported.

Abstract

Atomically precise copper nanoclusters (NCs) are of immense interest for a variety of applications, but have remained elusive. Herein, we report the isolation of a copper NC, [Cu25H22(PPh3)12]Cl (1), from the reaction of Cu(OAc) and CuCl with Ph2SiH2, in the presence of PPh3. Complex 1 has been fully characterized, including analysis by X-ray crystallography, XANES, and XPS. In the solid state, complex 1 is constructed around a Cu13 centered-icosahedron and formally features partial Cu(0) character. XANES of 1 reveals a Cu K-edge at 8979.6 eV, intermediate between the edge energies of Cu(0) and Cu(I), confirming our oxidation state assignment. This assignment is further corroborated by determination of the Auger parameter for 1, which also falls between those recorded for Cu(0) and Cu(I).

Abstract

We are interested in deriving various full Green functions through general Ward–Takahashi identities (WTIs) for quantized field theories. With the help of a postulate of gauge group parameter, the general local gauge transformation laws preserving the gauge-invariance of the generating functional itself of QED model have been established successfully. By using path-integral technique, the various WTIs with resulting anomaly terms are derived under the gauge transformations. The arising of Jacobian factor from the integration measure gives a viable possibility to express full Green function. As a consequence, the complete expressions of the full vector, the full axial-vector, the full tensor vertex functions and so on are presented respectively by solving the complete set of the WTIs in the momentum space without considering the constraint imposing any Ansatz. In addition, anomaly function also provides an effective means to judge the divergence of variant coupling currents on fields.

Abstract

Phosphite, which often exists in growth solutions obtained directly from commercial P 2 O 5 , was found to have significant inhibiting effects on the growth of pyramidal face of KDP crystals. K(D x H 1-x ) 2 PO 4 (referred to as DKDP) crystals with different deuterium fraction x were grown and the optical performances were investigated. The absorption coefficients at 1.05 μm decreases monotonically with the increase of x. The transmission threshold shift from 1.65μm at x=0 to 2.10 μm at x=0.96. The high temperature phase transition temperature and latent heat were measured using the method of differential scanning calorimetry (DSC). Thermal conditioning experiments were carried out at 180°C and 140°C for KDP and DKDP, respectively. After conditioning, a different degree of improvement was observed in the optical homogeneity of the samples, while the laser damage threshold and light absorption coefficient showed no significant change.

Abstract

Tight junctions form a narrow, continuous seal that surrounds each endothelial and epithelial cell at the apical border, and act to regulate the movement of material through the paracellular pathway. In the mammary gland, the tight junctions of the alveolar epithelial cells are impermeable during lactation, and thus allow milk to be stored between nursing periods without leakage of milk components from the lumen. Nonetheless mammary epithelial tight junctions are dynamic and can be regulated by a number of stimuli. Tight junctions of the mammary gland from the pregnant animal are leaky, undergoing closure around parturition to become the impermeable tight junctions of the lactating animal. Milk stasis, high doses of oxytocin, and mastitis have been shown to increase tight junction permeability. In general changes in tight junction permeability in the mammary gland appear to be the results of a state change and not assembly and disassembly of tight junctions. Both local factors, such as intramammary pressure and TGF-beta, and systemic factors, such as prolactin, progesterone, and glucocorticoids, appear to play a role in the regulation of mammary tight junctions. Finally, the tight junction state appears to be closely linked to milk secretion. An increase in tight junction permeability is accompanied by decrease in the milk secretion rate, and conversely, a decrease in tight junction permeability is accompanied by an increase in the milk secretion rate.

Abstract

We use angle resolved photoemission spectroscopy to probe the electronic excitations of the non-superconducting state that exists between the antiferromagnetic Mott insulator at zero doping and the superconducting state at larger dopings in Bi_2Sr_2CaCu_2O_{8+��}. We find that this state is a nodal liquid whose excitation gap becomes zero only at points in momentum space. Despite exhibiting a resistivity characteristic of an insulator and the absence of coherent quasiparticle peaks, this material has the same gap structure as the d-wave superconductor. We observe a smooth evolution of the spectrum across the insulator-to-superconductor transition, which suggests that high temperature superconductivity emerges when quantum phase coherence is established in a non-superconducting nodal liquid., 16 pages, 5 figures

Abstract

Purpura fulminans is a rare form of disseminated intravascular coagulation characterized by rapidly progressive purpuric lesions, hypotension and, in some cases, fever. In neonates, purpura fulminans usually develops following deficiency of anticoagulant protein C or S, although acquired forms have been described. The management of disseminated intravascular coagulation is still controversial, with some studies finding a positive effect of anticoagulants and others showing no effect or even a detrimental one. Therefore, at present, management is limited to the treatment of underlying disease and replacement of clotting factors. Personal experience is reported on the efficacy of heparin in combination with antithrombin III in the treatment of purpura fulminans in two preterm neonates who did not have inherited deficiency of protein C or S and developed the disease possibly following prolonged labor (36 hours) in the first case, and maternal neoplasia, in the second. Both neonates presented with widespread cyanotic areas rapidly evolving in purpuric lesions and hemorrhagic bullae. Laboratory tests (prolonged prothrombin and partial thromboplastin time, fibrinogen and antithrombin III concentrations below normal ranges, d-dimer highly positive) were consistent with disseminated intravascular coagulation. In both cases anticoagulant treatment with heparin (50 UI/kg in bolus followed by 15 UI/kg/h) and antithrombin III was associated with resolution of disseminated intravascular coagulation and prompt amelioration of the purpuric lesions, without apparent side effects.

Abstract

This study aimed to evaluate the efficacy and safety of remimazolam tosylate versus propofol in patients undergoing colonoscopy. In this multicentered, blinded, randomized, active-controlled, non-inferior phase III trial, 384 eligible patients who were about to undergo colonoscopy were randomized as a ratio of 1:1 into remimazolam and propofol group. Procedure success was assessed and defined as the completion of colonoscopy without administration of rescue sedative agent or more than 5 top-ups of trial drug in any 15 minute-period after initial administration of trial drug. Sedation quality was evaluated by Modified Observer’s Assessment of Alertness/Sedation score. Treatment-emergent adverse events were recorded. Procedure success rate was 96.91% (188/194) in remimazolam group and 100% (190/190) in propofol group, and the difference in rate was -3.09% with 95% confidence interval (CI) of -5.53%~-0.66%. Since the lower limit of 95% CI was greater than the non-inferiority margin of -8.00%, the efficacy of remimazolam tosylate was non-inferior to propofol. Besides, induction time of sedation was increased (P0.05) or time to discharge (P>0.05) were unchanged. For safety assessment, total treatment-emergent adverse events were decreased in remimazolam group compared to propofol group (P
