As an indispensable component of perovskite solar cells (PSCs), the commonly used Au and Ag electrodes still have some problems such as high cost and instability issues with regard to being corroded by iodide ions. In this paper, we report stacking perovskite solar cells (S-PSCs), which can avoid the use of precious metal electrodes and reduce the cost of devices and the requirements of equipment compared to conventional PSCs. The S-PSCs are composed of two semicells a photoanode and a counter electrode (CE). For stacked devices, effective contact of the photoanode/CE interface is very important to the performance of the device. We used poly(3,4-ethylenedioxythiophene)poly(styrenesulfonate) (PEDOTPSS) as the electrode and modified it by hexamethylenediammonium diiodide (HDADI2) to improve its physical and electrical properties. The surface of the HDADI2-modified PEDOTPSS becomes rough and achieves higher adhesion, which enables the photoanode and CE to be sufficiently connected. In addition, the energy-level structure of the HDADI2-modified PEDOTPSS matches better with that of the adjacent functional layers. Therefore, the S-PSCs performance has been significantly improved. Under an illumination area of 1 cm2, the power-conversion efficiency (PCE) of the S-PSCs can reach 15.21%. Moreover, the S-PSCs can be disassembled and assembled flexibly and repeatedly disassembled 500 times with almost no change in the PCE. This has a positive impact on cell maintenance and modular production. Fluorescence polarization (FP) and fluorescence anisotropy (FA) microscopy are powerful imaging techniques that allow to translate the common FP assay capabilities into the in vitro and in vivo cellular domain. As a result, they have found potential for mapping drug-protein or protein-protein interactions. Unfortunately, these imaging modalities are ratiometric in nature and as such they suffer from excessive noise even under regular imaging conditions, preventing accurate image-feature analysis of fluorescent molecules behaviors. We present a high dynamic range (HDR)-based FA imaging modality for improving image quality in FA microscopy. The method exploits ad hoc acquisition schemes to extend the dynamic range of individual FP channels, allowing to obtain FA images with increased signal-to-noise ratio. A direct comparison between FA images obtained with our method and the standard, clearly indicates how an HDR-based FA imaging approach allows to obtain high-quality images, with the ability to correctly resolve image features at different values of FA and over a substantially higher range of fluorescence intensities. The method presented is shown to outperform standard FA imaging microscopy narrowing the spread of the propagated error and yielding higher quality images. The method can be effectively and routinely used on any commercial imaging system and could be also translated to other microscopy ratiometric imaging modalities.

We conducted a cohort study to understand patterns of anti-retroviral therapy (ART) adherence during pregnancy, postpartum and non-pregnancy follow-up among women initiating ART in public clinics offering Option B+ in rural Uganda and urban South Africa. We collected survey data, continuously monitored ART adherence (Wisepill), HIV-RNA and pregnancy tests at zero, six and twelve months from women initiating ART in Uganda and South Africa, 2015 to 2017. The primary predictor of interest was follow-up time categorized as pregnant (pregnancy diagnosis to pregnancy end), postpartum (pregnancy end to study exit) or non-pregnancy-related (neither pregnant nor postpartum). Fractional regression models included demographics and socio-behavioural factors informed by the Behavioral Model for Vulnerable Populations. We evaluated HIV-RNA at 12months by ever- versus never-pregnant status. In Uganda, 247 women contributed 676, 900 and 1274months of pregnancy, postpartum and non-pregnancy-related follow-up. Median ARTnda maintained high adherence with 91% of ever-pregnant and 86% of never-pregnant women suppressing HIV-RNA at 12months. Women in urban South Africa struggled with adherence, particularly during postpartum follow-up with median adherence of 40% and 57% of women with HIV-RNA suppression at one year, suggesting a crisis for postpartum women with HIV in South Africa. Findings suggest that effective interventions should promote emotional support.

The cytotoxicity of Ru(II) and Ir(III) complexes has been evaluated against different human cancer cell lines (HeLa, MCF-7, and A549) in a concentration-dependent manner. The new iridium complex with isopropyl substituent in the phenyl ring of the 2H-indazole moiety showed good cytotoxic activity against MCF-7 cells with an IC50 value 3.5 μM. The complex also exhibited cytotoxicity comparable to that of cisplatin. The ability of this compound inducing apoptosis was tested by nuclear condensation, cell membrane blebbing and caspase 3/7 activation. Further, this iridium complex is capable of inhibiting cancer cell migration when tested in MCF-7 cell line. Subsequently, we have studied the DNA binding and protein binding ability of the newly synthesized iridium complex.
