This paper asks whether investigation into the ontology of the extended family can help us to think about and resolve questions concerning the nature of the family's decision-making authority where organ donation is concerned. Here, "extended family" refers not to the multigenerational family all living at the same time, but to the family extended past its living boundaries to include the dead and the not yet living. How do non-existent members of the family figure into its ontology? Does an answer to this question help to resolve questions about the distribution of authority within the extended family?The Western focus on personal autonomy as the normative basis for securing persons' consent to their treatment renders this autonomy-based approach to informed consent vulnerable to the charge that it is based on an overly atomistic understanding of the person. This leads to a puzzle how does this generally-accepted atomistic understanding of the person fits with the emphasis on familial consent that occurs when family members are provided with the opportunity to veto a prospective donor's wish to donate after she has died and her organs are being considered for harvesting? It is argued in this paper that this charge can be met and this puzzle dissolved once it is recognized that autonomy is an inherently social concept.China is developing an ethical and sustainable organ donation and procurement system based on voluntary citizen donation. The gift-of-life metaphor has begun to dominate public discussion and education about organ donation. However, ethical and legal problems remain concerning this "gift-of-life" discourse In what sense are donated organs a "gift-of-life"? What constitutes the ultimate worth of such a gift? On whose authority should organs as a "gift-of-life" be donated? There are no universal answers to these questions; instead, responses must be compatible with local cultural values. This paper argues that from a Confucian point of view, organs should be viewed as a gift from the donor's family, and that final dispositional authority should also rest with the donor's family. The worth of such a "gift" rests on the virtue of ren, the origin of which is family love. Ultimately, I will argue that a family-based consent model for deceased organ donation is not merely justified, but morally required in the Chinese cultural context.Background The transcription factor Hypoxia Inducible Factor 1 alpha (HIF-1α) is responsible for tissue homeostasis and regeneration and presents reduced functionality in advanced age. In addition to absence of oxygen, sequestration of iron also stimulates HIF-1α. Therefore, we analyzed the efficacy of the iron-chelator Deferiprone to stimulate dermal fibroblasts. Objectives Our main objective is to quantify the Deferiprone concentrations able to stimulate dermal fibroblasts in-vitro and to correlate the effective DFP concentrations with its ability to penetrate the epidermis, reach the dermis and activate HIF-1α in-vivo. Methods We measured cell proliferation, the metabolic activity, HIF-1α expression and Lactatdehydrogenase levels of both young and aged fibroblasts after a 24h in-vitro preconditioning with Deferiprone. Moreover, we evaluated cell survival rates and morphology with different cellular stainings. Finally, we performed a transdermal permeation study with a 1% Deferiprone topical formulation to quantify the concentration able to reach the dermis. Results In vitro administration of iron-chelation therapy (DFP 312.5 µg/ml - 156 µg/ml) on aged fibroblasts resulted in an activation of different anti-aging processes. The concentration able to reach the dermis after 24h was 1.5% (0.15 mg/ml), which corresponds well with the effective doses of our laboratory analyses. Conclusion The activation of HIF-1α via DFP enhances cell metabolism, proliferation and survival of fibroblasts while reducing LDH levels. Modulation of HIF-1α is linked to activation of key regeneration enzymes and proteins, and by proxy, anti-aging. Therefore, the anti-aging properties of DFP and its satisfactory dermal penetration make it a promising regenerative agent.Objectives The transmission of carbapenemase-producing Enterobacterales (CPE) poses an increasing healthcare challenge. selleck chemical A range of infection prevention activities, including screening and contact precautions, are recommended by international and national guidelines. We evaluated the introduction of an enhanced screening programme in a multisite London hospital group. Methods In June 2015, an enhanced CPE policy was launched in response to a local rise in CPE detection. This increased infection prevention measures beyond the national recommendations, with enhanced admission screening, contact tracing and environmental disinfection, improved laboratory protocols and staff/patient education. We report the CPE incidence and trends of CPE in screening and clinical cultures and the adoption of enhanced CPE screening. All non-duplicate CPE isolates identified between April 2014 and March 2018 were included. Results The number of CPE screens increased progressively, from 4530 in July 2015 to 10 589 in March 2018. CPE detection increased from 18 patients in July 2015 (1.0 per 1000 admissions) to 50 patients in March 2018 (2.7 per 1000 admissions). The proportion of CPE-positive screening cultures remained at approximately 0.4% throughout, suggesting that whilst the CPE carriage rate was unchanged, carrier identification increased. Also, 123 patients were identified through positive CPE clinical cultures over the study period; there was no significant change in the rate of CPE from clinical cultures per 1000 admissions (P = 0.07). Conclusions Our findings suggest that whilst the enhanced screening programme identified a previously undetected reservoir of CPE colonization in our patient population, the rate of detection of CPE in clinical cultures did not increase.Salt and Drought Induced RING finger1 (SDIR1) is a RING-type E3 ubiquitin ligase that plays a pivotal role in ABA-mediated response to salinity and drought stress by the ubiquitination pathway in some plant species. However, its function in wheat (Triticum aestivum) is unknown. Here, we isolated a SDIR1 member, TaSDIR1-4A in wheat and characterized its E3 ubiquitin ligase activity. DNA polymorphism assays showed the presence of two nucleotide variation sites in the promoter region of TaSDIR1-4A; these formed haplotypes Hap-4A-1 and Hap-4A-2 that were detected in wheat populations. Association analysis showed that TaSDIR1-4A was associated with 1,000-grain weight (TGW) in all test environments, including well watered and heat stress situations. Genotypes with Hap-4A-2 had higher TGW than those with Hap-4A-1. The phenotypes in both gene-silenced wheat and transgenic Arabidopsis showed that TaSDIR1-4A was a negative regulator of grain size. Gene expression assays revealed that TaSDIR1-4A was most highly expressed in flag leaves, and expression levels of TaSDIR1-4A were higher in Hap-4A-1 accessions than in Hap-4A-2 accessions.
