Current trends in the characterization and monitoring of vascular response to cancer therapy.

Tumor vascular physiology is an important determinant of disease progression as well as the therapeutic outcome of cancer treatment. Angiogenesis or the lack of it provides crucial information about the tumor's blood supply and therefore can be used as an index for cancer growth and progression. While standalone anti-angiogenic therapy demonstrated limited therapeutic benefits, its combination with chemotherapeutic agents improved the overall survival of cancer patients.

Social norms, diffusion, and women's risk of intimate partner violence in Nepal: Impact assessment of a social and behavior Change communication intervention (Change Starts at home).

Introduction: Intimate partner violence (IPV) is a significant public health, human rights, and development issue. While existing evidence posits that addressing social norms is key to IPV prevention, successful IPV interventions that include a norms approach are limited in number and methodological rigor and rarely include a formal investigation of the diffusion of intervention impact. We contribute novel findings to this intellectual and programmatic space with evidence on a social and behavior change communication (SBCC) intervention (Change Starts at Home) in Nepal designed to prevent IPV and shift social norms towards greater gender equity.

Correction: Highly efficient green up-conversion emission from fluoroindate glass nanoparticles functionalized with a biocompatible polymer.

[This corrects the article DOI: 10.1039/D2RA03171J.].

Highly efficient green up-conversion emission from fluoroindate glass nanoparticles functionalized with a biocompatible polymer.

Up-conversion nanoparticles have garnered lots of attention due to their ability to transform low energy light (near-infrared) into high-energy (visible) light, enabling their potential use as remote visible light nano-transducers. However, their low efficiency restricts their full potential. To overcome this disadvantage, fluoroindate glasses (InF) doped at different molar concentrations of Yb and Er were obtained using the melting-quenching technique, reaching the highest green emission at 1.

Fusion of Sentinel-1 and Sentinel-2 data in mapping the impervious surfaces at city scale.

Urbanization creates new development in open spaces and agricultural fields, synonymous with increasing impervious surfaces. Such surfaces restrain the natural infiltration of water, and directly affect the non-point source pollution. Thus, consequential events like flooding and surface water degradation require spatial and quantitative information on impervious surfaces.

Photoacoustic (PA) or optoacoustic imaging is a hybrid technique that allows three-dimensional imaging with high spatial resolution.

Induced Pluripotent Stem Cell-Derived Endothelial Networks Accelerate Vascularization But Not Bone Regeneration.

Vascularization is critical for engineering mineralized tissues. It has been previously shown that biomaterials containing preformed endothelial networks anastomose to host vasculature following implantation. However, the networks alone may not increase regeneration.

Characterization of Aminobenzylphenols as Protein Disulfide Isomerase Inhibitors in Glioblastoma Cell Lines.

Disulfide bond formation is a critical post-translational modification of newly synthesized polypeptides in the oxidizing environment of the endoplasmic reticulum and is mediated by protein disulfide isomerase (PDIA1). In this study, we report a series of α-aminobenzylphenol analogues as potent PDI inhibitors. The lead compound, , is a covalent nanomolar inhibitor of PDI, and the combination of analogues with glutathione synthesis inhibitor buthionine sulfoximine (BSO) leads to synergistic cell growth inhibition.

Up-regulation of hypoxia-inducible factor antisense as a novel approach to treat ovarian cancer.

Ovarian cancer (OC) is estimated to kill ~14,000 women in the United States in 2019. Current chemotherapies to treat OC initially show therapeutic efficacy but frequently drug resistance develops, at which point therapies with alternative targets are needed. Herein, we are describing a novel approach to sensitize these tumors to standard chemotherapies by increasing the transcription of hypoxia-inducible factor antisense.

Intimate partner violence in Nepal: Latent patterns and association with depressive symptoms.

Existing data suggest that there are distinct patterns (or classes) of intimate partner violence (IPV) experience that depart from dichotomous categorizations used to monitor progress toward Sustainable Development Goal 5.2. Less is known about the patterning of IPV in non-Western settings.

Impact of the Change Starts at Home Trial on Women's experience of intimate partner violence in Nepal.

Intimate partner violence (IPV) affects 1 in 3 women worldwide. Research in low- and middle-income countries suggests that multicomponent interventions incorporating media, group work, and community mobilization may be effective at changing social norms that enable such violence. Our study aimed to evaluate the impact of a radio programme plus community engagement versus radio programming alone on the 12-month prevalence of IPV.

Photoacoustic Imaging in Tissue Engineering and Regenerative Medicine.

Several imaging modalities are available for investigation of the morphological, functional, and molecular features of engineered tissues in small animal models. While research in tissue engineering and regenerative medicine (TERM) would benefit from a comprehensive longitudinal analysis of new strategies, researchers have not always applied the most advanced methods. Photoacoustic imaging (PAI) is a rapidly emerging modality that has received significant attention due to its ability to exploit the strong endogenous contrast of optical methods with the high spatial resolution of ultrasound methods.
