A general partial wetting model to describe an intermediate wetting state is proposed in this study to explain the deviations between the experimental results and classical theoretical wetting models for hydrophobic surfaces. We derived a theoretical partial wetting model for the static intermediate wetting state based on the thermodynamic energy minimization method. The contact angle based on the partial wetting model is a function of structural parameters and effective wetting ratio f, which agrees with the classical Wenzel and Cassie-Baxter models at f = 1 and 0, respectively. Si samples including porous surfaces, patterned surfaces and hierarchical nano/microstructured surfaces were prepared experimentally, having the same chemical composition but different physical morphology. We found that the experimental water contact angles deviate significantly from the classical Wenzel and Cassie-Baxter models but show good agreement with the proposed partial wetting model.Solid state NIR-to-visible photon upconversion (UC) mediated by triplet-triplet annihilation (TTA) is necessitated by numerous practical applications. Yet, efficient TTA-UC remains a highly challenging task. In this work palladium phthalocyanine-sensitized NIR-to-vis solid UC films based on a popular rubrene emitter are thoroughly studied with the primary focus on revealing the impact of t-butyl substitution in rubrene on the TTA-UC performance. The solution-processed UC films were additionally doped with a small amount of emissive singlet sink tetraphenyldibenzoperiflanthene (DBP) for collecting upconverted singlets from rubrene and in this way diminishing detrimental singlet fission. Irrespective of the excitation conditions used, t-butyl-substituted rubrene (TBR) was found to exhibit enhanced TTA-UC performance as compared to that of rubrene at an optimal emitter doping of 80 wt% in polystyrene films. Explicitly, in the TTA dominated regime attained at high excitation densities, 4-fold higher UC quantum yield (ΦUC) achieved in TBR-based films was caused by the reduced fluorescence concentration quenching mainly due to suppressed singlet fission. Under low light conditions, i.e. in the regime governed by spontaneous triplet decay, even though triplet exciton diffusion was obstructed in TBR films by t-butyl moieties, the subsequently reduced TTA rate was counterbalanced by both suppressed singlet fission and non-radiative triplet quenching, still ensuring higher ΦUC of these films as compared to those of unsubstituted rubrene films.In this study, new fluorescent quinoxalines were developed as G4 topology-selective probes. Among them, the most promising one could light up parallel G4s at two separate excitation wavelengths, exhibiting dual-channel emission, and light up nonparallel G4s at one excitation wavelength, showing mono-channel emission.Naturally occurring bioactive food components such as dietary polyphenols have shown many beneficial biological activities due to their good antioxidant properties. Among them significant attention has been given to resveratrol (RV) in recent years as it plays a promising role in cancer prevention. It has demonstrated anti-proliferative effects, as well as the ability to inhibit the initiation and progression of induced cancer in a wide variety of tumor models. However, the benefits of its therapeutic effects were found to be limited due to its poor pharmacokinetic properties such as poor aqueous solubility, instability and extensive first pass metabolism. To overcome these limitations, the present study aimed to synthesize thermosensitive copolymeric nanoparticle encapsulated formulations of resveratrol-nanoresveratrol (NRV) and evaluate their in vitro anticancer activity and inhibitory effect on 12-O-tetradecanoylphorbol-13-acetate (TPA)-promoted skin inflammation and tumorigenesis in Swiss albino mice. For this purpose PNIPAAM-PEG based thermosensitive copolymeric nanoparticles were synthesized followed by the encapsulation of RV in their hydrophobic core. This enhanced the therapeutic bioavailability of resveratrol. Nanoresveratrol demonstrated stronger antioxidant activity and comparable anticancer efficacy to free resveratrol. Nanoparticles were characterized by IR, NMR, DLS and TEM. The best results were obtained with NRV at significantly lower doses. NRV demonstrated better in vitro anticancer activity against melanoma cell line B16. It showed comparable reduction of TPA induced skin edema, hyperplasia and oxidative stress response. In the promotion phase, a significant reduction was found in tumor incidence and tumor burden in mice pre-treated with NRV. Moreover, at all doses NRV altered Bax and Bcl2 expressions which lead to the induction of apoptosis.Liver cancer is one of the most prevalent cancers and the third leading cause of cancer-related deaths worldwide. Liver cancer is insensitive to chemotherapeutic drugs due to its intrinsic or acquired drug resistance and the inability of delivering sufficient drugs to tumors via current chemotherapy. The emergence of nanomedicines offers a potential solution for this challenge. Nanomedicines utilize nanoscale or nanostructured materials in medicines for particular medical purposes. Napabucasin concentration In this review, we illustrate the recent developments of various nanomedicines for liver cancer by presenting selected examples at different stages. Diverse nanomaterials, varied targeting moieties, and specific strategies for controlled release of nanomedicines for liver cancer therapy are summarized. Multifunctional nanomedicines for liver cancer are also discussed. This comprehensive review is aimed at providing quick access for readers to the cutting-edge nanomedicines in liver cancer therapy.A search in an all-jet final state for new massive resonances decaying to W W , W Z , or Z Z boson pairs using a novel analysis method is presented. The analysis is performed on data corresponding to an integrated luminosity of 77.3 fb - 1 recorded with the CMS experiment at the LHC at a centre-of-mass energy of 13 Te . The search is focussed on potential narrow-width resonances with masses above 1.2 Te , where the decay products of each W or Z boson are expected to be collimated into a single, large-radius jet. The signal is extracted using a three-dimensional maximum likelihood fit of the two jet masses and the dijet invariant mass, yielding an improvement in sensitivity of up to 30% relative to previous search methods. No excess is observed above the estimated standard model background. In a heavy vector triplet model, spin-1 Z ' and W ' resonances with masses below 3.5 and 3.8 Te , respectively, are excluded at 95% confidence level. In a bulk graviton model, upper limits on cross sections are set between 27 and 0.2 fb for resonance masses between 1.2 and 5.2 Te , respectively. The limits presented in this paper are the best to date in the dijet final state. © CERN for the benefit of the CMS collaboration 2020.Midazolam is a commonly used benzodiazepine in palliative care and is considered one of the four essential drugs needed for the promotion of quality care in dying patients. Acting on the benzodiazepine receptor, it promotes the action of gamma-aminobutyric acid. Gamma-aminobutyric acid action promotes sedative, anxiolytic, and anticonvulsant properties. Midazolam has a faster onset and shorter duration of action than other benzodiazepines such as diazepam and lorazepam lending itself to greater flexibility in dosing than other benzodiazepines. The kidneys excrete midazolam and its active metabolite. Metabolism occurs in the liver by the P450 system. This article examines the pharmacology, pharmacodynamics, and clinical uses of midazolam in palliative care. © The Author(s), 2020.Background Reminiscence is used in a range of different interventions in palliative care, for example, Dignity Therapy or Life Review. However, literature has focused mainly on the methodology, and little has been published on patients' priorities and primary concerns. Objective This study looks at themes emerging in a reminiscence intervention with patients confronted with a life-limiting disease. Interviews were audiotaped and transcribed verbatim. Transcripts were analysed using thematic analysis. Setting/subjects Seventeen patients who were receiving palliative care at the University Hospital Bonn participated in interviews reviewing parts or phases of their lives. Results Patients expressed satisfaction and a sense of well-being with the intervention. Major themes emerging in the interviews were the factors involved in the development and expression of personality, such as character-forming influences, self-image, self-awareness, and philosophy of life. Talking about personality was entangled with influences from growing up, qualification/job, partner/spouse, children, resources, twists of fate/crossroads, and coping. Conclusion The topics emerging from the interviews differed from the scope of guiding questions in common reminiscence methods like Life Review or Dignity Therapy. The underlying motivation of patients seemed to be the search for identity and continuity in one's life. © The Author(s), 2019.The traditional approach to research ethics is to ensure that all ethical issues are adhered to through the scrutiny of research proposals by research ethics committees, themselves sitting within national research governance frameworks. The current approach implies that all potential ethical issues can be considered and mitigated prior to the research. This article is a perspective piece whereby we consider how this approach, on its own, is not enough to ensure ethical practice. We draw attention to the limitations of current ethical procedures in the inherent detachment between the researcher and research participants. We argue that applying a person-centred approach to research ethics allows for contextual and situational factors and places the relationship between research participants and researcher as central. © The Author(s), 2019.Voluntary stopping of eating and drinking (VSED) is a well-known phenomenon among palliative care professionals. This study intent to distinguish between different forms of VSED. In a qualitative interview study 18 relatives were interviewed about their experiences of caring a person during VSED. Different forms of oral nutrition refusal and different forms of VSED were found and described. The study results help members of the multidisciplinary team to manage the situation appropriately. © The Author(s), 2019.Multiple myeloma represents 2% of all new cancer diagnoses in the United Kingdom and accounts for 2% of all cancer deaths. In the past few decades, there have been huge improvements in life expectancy which have been driven by novel therapeutic agents, autologous stem cell transplants and intensified supportive care. This review will discuss the pathogenesis of multiple myeloma, current management approaches and the direction of future treatments. In addition, this review will highlight the high burden of symptoms that patients experience and therefore the great benefits that can be gained from specialist palliative care input. © The Author(s), 2019.Cancer cell lines are not homogeneous nor are they static in their genetic state and biological properties. Genetic, transcriptional and phenotypic diversity within cell lines contributes to the lack of experimental reproducibility frequently observed in tissue-culture-based studies. While cancer cell line heterogeneity has been generally recognized, there are no studies which quantify the number of clones that coexist within cell lines and their distinguishing characteristics. We used a single-cell DNA sequencing approach to characterize the cellular diversity within nine gastric cancer cell lines and integrated this information with single-cell RNA sequencing. Overall, we sequenced the genomes of 8824 cells, identifying between 2 and 12 clones per cell line. Using the transcriptomes of more than 28 000 single cells from the same cell lines, we independently corroborated 88% of the clonal structure determined from single cell DNA analysis. For one of these cell lines, we identified cell surface markers that distinguished two subpopulations and used flow cytometry to sort these two clones.
