Photobrightening in Lead Halide Perovskites: Observations, Mechanisms, and Future Potential

There has been a meteoric rise in the commercial potential of lead halide perovskite optoelectronic devices since photovoltaic cells and light-emitting diodes based on these materials were first demonstrated. One key challenge common to each of these optoelectronic devices is the need to suppress nonradiative recombination, a process that limits the maximum achievable efficiency in photovoltaic cells and light-emitting diodes. In this Progress Report, recent studies that seek to minimize this loss pathway in perovskites through a photobrightening treatment, whereby the luminescence efficiency is enhanced through a light illumination passivation process are examined. The sensitivity of this effect to various experimental considerations is examined, including atmosphere, photon energy, photon dose, and also the role of perovskite composition and morphology; under certain conditions there can even be photodarkening effects. Consideration of these factors is critical to resolve seemingly conflicting literature reports. Proposed mechanisms are scrutinized, revealing that there is now some consensus but further work is needed to identify the specific defects being passivated and elucidate universal mechanisms. Finally, the prospects for these treatments to minimize halide migration and push the properties of polycrystalline films towards those of their single-crystal counterparts are discussed.

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.

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.

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.

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.

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.

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.

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.

FAM225A promotes sorafenib resistance in hepatocarcinoma cells through modulating miR-130a-5p-CCNG1 interaction network

Chemotherapy resistance is still a key hurdle in current hepatocellular carcinoma (HCC) treatment. Therefore, clarifying the molecular mechanisms contributing to this acquired resistance is urgent for the effective treatment of liver cancer. In this research, we observed that lncRNA FAM225A expression is dramatically up-regulated not only in HCC tissues and cell lines but also in sorafenib-resistant HepG2/SOR cells. Moreover, FAM225A knockdown significantly weakened HepG2/SOR cells resistance to sorafenib treatment by MTT (3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide) assay. Similar results were obtained from the tumor xenograft model in mice. Further mechanistic researches revealed that the direct interaction between FAM225A and miR-130a-5p, while miR-130a-5p negatively modulated Cyclin G1 (CCNG1) expression by targeting 3’UTR of CCNG1. MiR-130a-5p inhibition or CCNG1 overexpression could partially offset FAM225A knockdown-induced increased viability of HepG2/SOR cells in response to sorafenib challenge. Collectively, our findings provide evidence that FAM225A/miR-130a-5p/CCNG1 interaction network regulates the resistance of HCC cells to sorafenib treatment and could supply a possible strategy for restoring sorafenib sensitivity in HCC therapy.

Pharmacologic treatment of orthostatic hypotension

Neurogenic orthostatic hypotension (OH) is a disabling disorder caused by impairment of the normal autonomic compensatory mechanisms that maintain upright blood pressure. Nonpharmacologic treatment is always the first step in the management of this condition, but a considerable number of patients will require pharmacologic therapies. Denervation hypersensitivity and impairment of baroreflex buffering makes these patients sensitive to small doses of pressor agents. Understanding the underlying pathophysiology can help in selecting between treatment options. In general, patients with low sympathetic reserve, i.e., those with peripheral noradrenergic degeneration (pure autonomic failure, Parkinson’s disease) and low plasma norepinephrine, tend to respond better to norepinephrine replacers (midodrine and droxidopa). On the other hand, patients with relatively preserved sympathetic reserve, i.e., those with impaired central autonomic pathways but spared peripheral noradrenergic fibers (multiple system atrophy) and normal or slightly reduced plasma norepinephrine, tend to respond better to norepinephrine enhancers (pyridostigmine, atomoxetine, and yohimbine). There is, however, a spectrum of responses within these extremes, and treatment should be individualized. Other nonspecific treatments include fludrocortisone and octreotide. The presence of associated clinical conditions, such as supine hypertension, heart failure, postprandial hypotension, PD, MSA, and diabetes need to be considered in the pharmacologic management of these patients.
