Background:
Palliative care as a specialist professional practice of care for people with advanced illness is becoming increasingly influential worldwide. This process is affected by global health ...inequalities as well as cultural dimensions of approaching death and practicing care in life-limiting illness.
Objectives:
The European Research Council-funded Globalizing Palliative Care (ENDofLIFE) project aims to understand how palliative care policies, discourses and practices are translated, adapted and reconstituted in diverse socio-cultural settings and how cultural dimensions of approaching death and local practices of care shape palliative care implementation.
Methods and Analysis:
Using a multi-scalar and multi-sited ethnographic approach, the project uses person-centered ethnography, participant observation, semi-structured interviewing, focus group discussions and policy and discourse analysis at transnational, national and local levels. Ethnographic case-studies are conducted in Brazil, India and Indonesia.
Discussion:
The globalizing palliative care project develops a novel ethnographic methodology of studying end-of-life care trajectories through long-term participant observation with individual patients and families as they manage and practice formal and informal health care in advanced illness. By analyzing how patients and families experience and navigate care over time, complemented by stakeholder interviews, the study advances critical theoretical insight into the relation between (large-scale and dynamically traveling) palliative care models, policies and discourses on the one hand and the experience and practice of palliative care in the lives of patients and informal care givers in local health care practices on the other hand. Insights are expected to benefit culturally situated palliative care policies and practices.

The present study aims to establish the morphological, morphometric, and immunostaining patterns of the steroidogenic enzymes 17β-HSD and 5α-reductase and androgen receptors (AR) during the prenatal ...development of the male gonad and epididymis of Cavia porcellus. Fetuses at 22, 25, 30, 40, 45, 50, and 60 days of gestation (DG) were used. Specimens were dissected and subjected to macroscopic, histological, histomorphometric, and immunohistochemical analyses. Genital and scrotal protrusions were identified in 22 DG embryos. Gonocytes were identified at 25 DG and the formation of primary testicular cords was observed at 30 DG. Through anatomical evaluation, we observed differentiation of the epididymis into the head, body, and tail at 45 DG. During development, there is a progressive decrease in the diameters of the testicular cords and epididymal ducts. 17β-HSD enzyme immunostaining was observed in Leydig cells at all ages, while 5α-reductase was observed in Leydig cell cytoplasm and gonocytes at 40, 50, and 60 DG. AR shows gonocyte labeling at 30 DG. Thus, from the second trimester of pregnancy, it is possible to observe patterns of anatomical development, such as genital and scrotal prominence (22 DG), the appearance of gonocytes in the testicular cords at 25 DG, and the beginning of the organization of primary testicular cords at 30 DG, suggesting sexual differentiation. The 17β-HSD, 5α-reductase, and ARs play an essential role in sexual development and differentiation, presenting immunostaining at different reproductive process times.
•Genital and scrotal protrusions identified in embryos at 22 days of gestation.•Gonocytes observed at 25 days: formation of primary testicular cords at 30 days.•Epididymis differentiation (head, body, tail) observed at 60 days.•Diameters of cords and ducts decrease progressively during development.•Immunostaining of 17β-HSD, 5α-reductase, AMH, and AR revealed roles in sexual development.

The concept of basic intrinsic value is important for axiology. Michael Zimmerman and Timothy Perrine each present necessary and sufficient conditions for something’s having basic intrinsic value. I ...argue that neither account is satisfactory. I present two objections to Zimmerman’s view. First, I argue that his view cannot accommodate some widely held and plausible views about the intrinsic value of knowledge and true belief. Second, I argue that it cannot accommodate some plausible views about the intrinsic value of states when one state occurs in virtue of the other. It cannot handle “clusters” of intrinsically valuable states. In the final section, I explain Perrine’s view and argue that his account also cannot accommodate some plausible views about the value of knowledge and true belief.

Trypanosoma and Leishmania parasites cause devastating tropical diseases resulting in serious global health consequences. These organisms have complex life cycles with mammalian hosts and insect ...vectors. The parasites must, therefore, survive in different environments, demanding rapid physiological and metabolic changes. These responses depend upon regulation of gene expression, which primarily occurs posttranscriptionally. Altering the composition or conformation of RNA through nucleotide modifications is one posttranscriptional mechanism of regulating RNA fate and function, and modifications including N6‐methyladenosine (m6A), N1‐methyladenosine (m1A), N5‐methylcytidine (m5C), N4‐acetylcytidine (ac4C), and pseudouridine (Ψ), dynamically regulate RNA stability and translation in diverse organisms. Little is known about RNA modifications and their machinery in Trypanosomatids, but we hypothesize that they regulate parasite gene expression and are vital for survival. Here, we identified Trypanosomatid homologs for writers of m1A, m5C, ac4C, and Ψ and analyze their evolutionary relationships. We systematically review the evidence for their functions and assess their potential use as therapeutic targets. This work provides new insights into the roles of these proteins in Trypanosomatid parasite biology and treatment of the diseases they cause and illustrates that Trypanosomatids provide an excellent model system to study RNA modifications, their molecular, cellular, and biological consequences, and their regulation and interplay.

Annona muricata L. (soursop) is traditionally used in the treatment of inflammatory diseases, cancer, and infections caused by fungi. The therapeutic activity explored by its medicinal use is ...generally associated with its phytoconstituents, such as acetogenins and alkaloids. However, its potential antifungal bioactivity as well as its mechanism of action remains to be established.
Aim of the study: To evaluate the antifungal activity of the ethanolic extract of A. muricata leaves against multidrug-resistant Candida albicans (ATCC® 10231).
Phytoconstituents were detected by UFLC-QTOF-MS. The minimum inhibitory concentration was determined, followed by the determination of the minimum fungicidal concentration. For planktonic cells, the growth curve and cell density were evaluated. Studies to understand the mechanism of action on the cell envelope involved crystal violet permeability, membrane extravasation, sorbitol protection, exogenous ergosterol binding assay, metabolic activity, and cell viability. Furthermore, mitochondrial membrane potential was assessed.
Our analyses demonstrated a significant inhibitory effect of A. muricata, with the ability to reduce fungal growth by 58% and cell density by 65%. The extract affected both the fungal plasma membrane and cell wall integrity, with significant reduction of the cell viability. Depolarization of the fungal mitochondrial membrane was observed after treatment with A. muricata. Rutin, xi-anomuricine, kaempferol-3O-rutinoside, nornuciferine, xylopine, atherosperminine, caffeic acid, asimilobine, s-norcorydine, loliolide, annohexocin, annomuricin, annopentocin, and sucrose were identified as extract bioactive components.
Our findings show that the A. muricata extract is a source of chemical diversity, which acts as a potential antifungal agent with promising application to the therapy of infections caused by C. albicans.

Complex functional materials play a crucial role in a broad range of energy‐related applications and in general for materials science. Revealing the structural mechanisms is challenging due to highly ...correlated coexisting phases and microstructures, especially for in situ or operando investigations. Since the grain sizes influence the properties, these microstructural features further complicate investigations at synchrotrons due to the limitations of illuminated sample volumes. In this study, it is demonstrated that such complex functional materials with highly correlated coexisting phases can be investigated under in situ conditions with neutron diffraction. For large grain sizes, these experiments are valuable methods to reveal the structural mechanisms. For an example of in situ experiments on barium titanate with an applied electric field, details of the electric‐field‐induced phase transformation depending on grain size and frequency are revealed. The results uncover the strain mechanisms in barium titanate and elucidate the complex interplay of stresses in relation to grain sizes as well as domain‐wall densities and mobilities.
This work reports in situ neutron diffraction experiments on a broad range of grain sizes of barium titanate. The study reveals the grain‐size‐dependent strain mechanisms and shows the competitiveness of neutron diffraction with high‐resolution synchrotron diffraction.
