Cytosolic delivery of peptides remains a challenging task owing to their susceptibility to enzymatic degradation and the existence of multiple intracellular barriers. Here, we report a new strategy to address these issues by decoration of a fluorous tag on the terminal of cargo peptides. The fluorous-tagged peptides were assembled into nanostructures, efficiently internalized by cells via several endocytic pathways and released into the cytosol after endosomal escape. They were relatively stable against enzymatic degradation and showed much higher efficiency than nonfluorinated analogs and cell penetrant peptide-conjugated ones. The proposed strategy also efficiently delivered a proapoptotic peptide into specific sites in the cells and restored the function of cargo peptide after cytosolic delivery. GS-9973 order The fluorous-tagged proapoptotic peptide efficiently inhibited tumor growth in vivo. This study provides an efficient fluorination strategy to promote the cytosolic delivery of peptides.Recently, extracellular vesicles (EVs) have been attracting strong research interest for use as natural drug delivery systems. We report an approach to manufacturing interleukin-10 (IL-10)-loaded EVs (IL-10+ EVs) by engineering macrophages for treating ischemic acute kidney injury (AKI). Delivery of IL-10 via EVs enhanced not only the stability of IL-10, but also its targeting to the kidney due to the adhesive components on the EV surface. Treatment with IL-10+ EVs significantly ameliorated renal tubular injury and inflammation caused by ischemia/reperfusion injury, and potently prevented the transition to chronic kidney disease. Mechanistically, IL-10+ EVs targeted tubular epithelial cells, and suppressed mammalian target of rapamycin signaling, thereby promoting mitophagy to maintain mitochondrial fitness. Moreover, IL-10+ EVs efficiently drove M2 macrophage polarization by targeting macrophages in the tubulointerstitium. Our study demonstrates that EVs can serve as a promising delivery platform to manipulate IL-10 for the effective treatment of ischemic AKI.Polygynous mating systems with group fidelity are a common animal organization, typically consisting of multiple females in a mated group with a single male for an extended period (sometimes referred to as harem polygyny). Single-male polygyny with reproductive fidelity occurs in invertebrates, bony fishes, and some tetrapods, such as lizards, mammals, and birds. In amphibians, reproductive fidelity in polygynous groups is not fully demonstrated. Combining data on larval development, molecular paternity assignment, and in situ behavioral observations, we reveal high fidelity during a prolonged breeding season in a Neotropical polygynous frog. Males dominate scarce breeding sites, guarding offspring, and mating exclusively with multiple females that exhibit dominance rank. This system likely evolved in response to intense competition for breeding sites and intrasexual competition for mates.G protein-coupled receptors (GPCRs) are the largest and pharmaceutically most important class of membrane proteins encoded in the human genome, characterized by a seven-transmembrane helix architecture and a C-terminal amphipathic helix 8 (H8). In a minority of GPCR structures solved to date, H8 either is absent or adopts an unusual conformation. The controversial existence of H8 of the class A GPCR neurotensin receptor 1 (NTS1) has been examined here for the nonthermostabilized receptor in a functionally supporting membrane environment using electron paramagnetic resonance, molecular dynamics simulations, and circular dichroism. Lipid-protein interactions with phosphatidylserine and phosphatidylethanolamine lipids, in particular, stabilize the residues 374 to 390 of NTS1 into forming a helix. Furthermore, introduction of a helix-breaking proline residue in H8 elicited an increase in ß-arrestin-NTS1 interactions observed in pull-down assays, suggesting that the structure and/or dynamics of H8 might play an important role in GPCR signaling. There is little understanding or focus on the patient's personal communicative perspective during their experience of clinical treatment. An exploratory study and a follow-up study were conducted at a large safety net hospital to determine whether and what patients wanted clinicians to know more about them as a person. A convenience sample of 230 patients was selected from 9 different clinical units within the hospital for exploratory interviews to determine whether patients wanted their clinical team to know about them as a person. Based on these findings, additional personal preference data of patients were collected from a census sample of 387 patients selected from 2 intensive care unit units and 2 medical-surgical units. The majority of patients in the exploratory study reported they wanted to tell their doctors/nurses some personal information about themselves, thought doctors/nurses could provide better care to them if they knew more about them as a person, and that communication between themselvy of patients preferred that their clinicians call them by their first name and identified specific personal information they wanted to share with the clinical care team. The data also showed a meaningful number of patients who did not want to share this information with others. This split in patient preferences is an important reminder that being aware of personal preferences of patients does not necessarily mean an invitation to increase intimacy in all clinician-patient communications.This study examined the association between interdepartmental transfers and the perceptions of care received by adult patients who were admitted and discharged from a 300-bed, not-for-profit community tertiary hospital in the Midwest. Transfers of patient care are daily and frequent hospital processes. However, limited attention has focused on the effect that intrahospital transfers of care have on the patient experience. Understanding this relationship is important, since value-based purchasing models directly tie patient experience measures into hospital reimbursements. The key finding of this study indicates that as patients' transfers increase, their perceptions of care decrease. Therefore, by reducing the frequency of interdepartmental transfers, patient satisfaction may increase. This research provides clinicians and administrators a better understanding of the relationship between a frequent and a daily hospital process (ie, interdepartmental transfers) and its influence on patients' perceptions of their experience.
