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. Sometimes chemists are able to propose two or more mechanisms that are consistent with the available data. If a proposed mechanism predicts the wrong experimental rate law, however, the mechanism must be incorrect.Welcome to check out more blogs about 58534-95-5, in my other articles.

Aucklandia lappa Causes Membrane Permeation of Candida albicans

Candida albicans is a major fungal pathogen in humans. In our previous study, we reported that an ethanol extract from Aucklandia lappa weakens C. albicans cell wall by inhibiting synthesis or assembly of both (1,3)-beta-D-glucan polymers and chitin. In the current study, we found that the extract is involved in permeabilization of C. albicans cell membranes. While uptake of ethidium bromide (EtBr) was 3.0% in control cells, it increased to 7.4% for 30 min in the presence of the A. lappa ethanol extract at its minimal inhibitory concentration (MIC), 0.78 mg/ml, compared to uptake by heat-killed cells. Besides, leakage of DNA and proteins was observed in A. lappa-treated C. albicans cells. The increased uptake of EtBr and leakage of cellular materials suggest that A. lappa ethanol extract induced functional changes in C. albicans cell membranes. Incorporation of diphenylhexatriene (DPH) into membranes in the A. lappa-treated C. albicans cells at its MIC decreased to 84.8%, after 60 min of incubation, compared with that of the controls, indicate that there was a change in membrane dynamics. Moreover, the anticandidal effect of theA. lappa ethanol extract was enhanced at a growth temperature of 40 degrees C compared to that at 35 degrees C. The above data suggest that the antifungal activity of the A. lappa ethanol extract against C. albicans is associated with synergistic action of membrane permeabilization due to changes in membrane dynamics and cell wall damage caused by reduced formation of (1,3)-beta-D-glucan and chitin.

Solvent Quality-Mediated Regioselective Modification of Gold Nanorods with Thiol-Terminated Polymers

Modification of nanorods (NRs) with functional polymer ligands is of great significance to enhance their surface chemistry and prompt their applications in many fields (e.g., photothermal therapy, bioimaging, and catalysis). However, the regioselective modification of AuNRs still remains a great challenge. Herein, we introduce a facile yet versatile strategy to achieve the regioselective modification of AuNRs through a solvent quality-mediated strategy. By employing a poor solvent of the original ligand cetyltrimethylammonium bromide (CTAB) as the medium in the modification, polymer ligands would selectively graft onto the two ends of AuNRs, while polymer ligands would graft onto the entire surface when employing a good solvent. This strategy demonstrates good reproducibility and is applicable to both hydrophilic and hydrophobic polymer ligand modifications. Moreover, by combing our strategy with the preoccupation route, the two ends and sidewall of AuNRs modified by two different polymers form an ABA-type building block, which can further self-assemble into well-ordered superstructures. Our finding provides a new opportunity for multifunctionalization of NRs.

Effect of beta-cyclodextrin, alcohol and temperature on the aggregation transitions of cationic/cationic surfactant systems

The mutual transitions between micelles and vesicles induced by beta-cyclodextrin (beta-CD), alcohol and temperatures, which had rarely been reported in mixed cationic/cationic surfactant systems, was studied in a dodecyltrimethylammonium chloride (DTAC)/didodecyldimethylammonium bromide (DDAB) aqueous solution. The effect of beta-CD, temperature and alcohol on this mixed system was investigated by the methods of turbidity, transmission electron microscopy (TEM), dynamic light scattering (DLS), and ‘H Nuclear magnetic resonance (H-1 NMR) measurements. We found that increasing the concentration of beta-CD would induce the micelle to vesicle (M-V) transition. While the vesicle to micelle (V-M) transition further occurred with increasing temperature or adding alcohol in this beta-CD/cationic/cationic mixed system. The M-V transition with adding beta-CD has the mechanism that the inclusion complexation of beta-CD to surfactants alters the composition ratio of the DDAB/DTAC systems, which changes the packing parameter. The V-M transition induced by temperature or alcohols is explained as the change of electrostatic repulsion interaction among the similar cationic polar heads in vesicles. The heat-induced V-M transition also verifies the M-V transition mechanism. Moreover, we firstly found that this heat-induced V-M transition was not only related to the percentage of DDAB concentration, but also to the total concentration of surfactant in cationic/cationic mixed surfactant systems.

Visible light promoted deaminative difluoroalkylation of aliphatic amines with difluoroenoxysilanes

A visible light promoted deaminative strategy for the difluoroalkylation reaction utilizing pyridinium-activated aliphatic primary amines and difluoroenoxysilane as substrates has been developed. This protocol is characteriazed by its mild reaction conditions and broad substrate scope, which converted a diverse array of amine-containing molecules to the alkyl-CF2COPh products. Moreover, the resulting products can be easily transformed into a vast array of structurally novel and interesting difluoro-containing moieties, therefore providing a facile route for applications in medicinal chemistry and the life sciences.

Minimizing the Trade-Off between Photocurrent and Photovoltage in Triple-Cation Mixed-Halide Perovskite Solar Cells

Its lower bandgap makes formamidinium lead iodide (FAPbI(3)) a more suitable candidate for single-junction solar cells than pure methylammonium lead iodide (MAPbI(3)). However, its structural and thermodynamic stability is improved by introducing a significant amount of MA and bromide, both of which increase the bandgap and amplify trade-off between the photocurrent and photovoltage. Here, we simultaneously stabilized FAPbI(3 )into a cubic lattice and minimized the formation of photoinactive phases such as hexagonal FAPbI(3) and PbI2 by introducing 5% MAPbBr(3) , as revealed by synchrotron X-ray scattering. We were able to stabilize the composition (FA(0.95)MA(0.05)Cs(0.05))Pb(I-0.95 Br-0.05)(3), which exhibits a minimal trade-off between the photocurrent and photovoltage. This material shows low energetic disorder and improved charge-carrier dynamics as revealed by photothermal deflection spectroscopy (PDS) and transient absorption spectroscopy (TAS), respectively. This allowed the fabrication of operationally stable perovskite solar cells yielding reproducible efficiencies approaching 22%.

A New Nitrogen Pd(II) Complex Immobilized on Magnetic Mesoporous Silica: A Retrievable Catalyst for C-C Bond Formation

A new nitrogen ligand, i.e. 1,3-di-(o-aminophenoxy)-2-propyl propargyl ether (DPPE), has been synthesized and characterized. Magnetic mesoporous silica composite (MNP@SiO2-SBA) was obtained via embedding magnetite nano-particles (MNPs) between SBA-15 channels. DPPE palladium dichloride (MNP@SiO2-SBA-DPPE-Pd(II)) was then prepared via click chemistry and fully characterized. The activity and recyclability of supported magnetic Pd(II) catalyst were evaluated in Heck coupling reaction after optimizing the optimal reaction conditions including solvent, amount of catalyst, base and temperature. Aryl iodides and aryl bromides showed enhanced activity compared to those of aryl chlorides in the Heck reaction. The catalyst was easily separated magnetically, reused in five runs sequentially, and no significant loss of activity was observed.

Enhanced miscibility and strain resistance of blended elastomer/pi-conjugated polymer composites through side chain functionalization towards stretchable electronics

This work presents improved compatibility in an elastomer/pi-conjugated polymer blend through side chain functionalization of the electronic polymer. Poly[(3-(6-bromohexyl)thiophene)-ran-(3-hexylthiophene)] (P3Br(x)HT, x = 0%-100%) was synthesized (i) to improve miscibility with polybutadiene (PB) elastomer through altered pi-pi interactions and (ii) to covalently bond across phase-segregated interfaces. Functionalization led to morphology with reduced domain sizes to improve crack onset strain from 7% to 40%. Furthermore, UV-activated crosslinking reinforced mechanically weak interfaces and yielded at least an additional 40% increase in crack onset strain. Charge mobility in PB/P3Br(x)HT organic field-effect transistors showed minimal dependence on bromide concentration and no negative effects from crosslinking. Functionalization was an effective method to reduce brittleness in PB/P3Br(x)HT blends through morphology modification and crosslinking to improve stability towards strain for potential stretchable electronic applications.
