05). ATXN3, ABI2 and GOLGB1 may predict higher RCC grades. Also, ABI2 may regulate platelet/lymphocyte ratio which may be an independent predictor of RCC and other forms of cancer.N -glycosylation may affect the safety and efficacy of biopharmaceuticals and is thus monitored during manufacturing. Mass spectrometry of the intact protein is increasingly used to reveal co-existing glycosylation variants. However, quantification of N -glycoforms via this approach may be biased by single hexose residues as introduced by glycation or O -glycosylation. Here, we describe a simple strategy to reveal actual N -glycoform abundances of therapeutic antibodies, involving experimental determination of glycation levels followed by computational elimination of the "hexosylation bias". We show that actual N -glycoform abundances may significantly deviate from initially determined values. Indeed, glycation may even obscure considerable differences in N -glycosylation patterns of drug product batches. Our observations may thus have implications for biopharmaceutical quality control. Moreover, we solve an instance of the problem of isobaricity, which is fundamental to mass spectrometry.The oxidative phosphorylation (OXPHOS) system is a dynamic system in which the respiratory complexes coexist with super-assembled quaternary structures called supercomplexes (SCs). The physiological role of SCs is still disputed. Here, we used zebrafish to study the relevance of respiratory SCs. We combined immunodetection analysis and deep data-independent proteomics to characterize these structures and found similar SCs to those described in mice, as well as novel SCs including III2 + IV2 , I + IV, and I + III2 + IV2 . To study the physiological role of SCs, we generated two null allele zebrafish lines for supercomplex assembly factor 1 (scaf1). scaf1-/- fish displayed altered OXPHOS activity due to the disrupted interaction of complexes III and IV. scaf1-/- fish were smaller in size and showed abnormal fat deposition and decreased female fertility. These physiological phenotypes were rescued by doubling the food supply, which correlated with improved bioenergetics and alterations in the metabolic gene expression program. These results reveal that SC assembly by Scaf1 modulates OXPHOS efficiency and allows the optimization of metabolic resources.We evaluate the relationship between hospital ownership and responses to a policy providing large financial incentives for vaginal deliveries and financial disincentives for C-sections. We compare for-profit, nonprofit, and public hospitals operating in a public health care system organized according to the quasi-market model. We first theoretically show that hospital ownership matters insofar different hospitals are characterized by different ethical preferences. We also show that competition makes ownership less important. We then consider the case study of Lombardy in Italy. We exploit spatial variation in hospital ownership and in market concentration at the local level to evaluate the relationship between ownership and the probability of C-section. According to theory, empirical results strongly suggest that competitive pressures from alternative providers tend to homogenize behaviors. selleck screening library However, in local monopolies, in presence of a strong monetary incentive toward vaginal deliveries, we do observe less C-section from private for-profit hospitals than from public and private nonprofit hospitals, especially when C-sections are medically appropriate."In a spare hour, I walk my dog … My favorite time of day is when I enjoy my walks in the garden …" Find out more about Xiaohua Liu in her Author Profile.The CDC7 kinase is essential for the activation of DNA replication origins and has been implicated in the replication stress response. Using a highly specific chemical inhibitor and a chemical genetic approach, we now show that CDC7 activity is required to coordinate multiple MRE11-dependent processes occurring at replication forks, independently from its role in origin firing. CDC7 localizes at replication forks and, similarly to MRE11, mediates active slowing of fork progression upon mild topoisomerase inhibition. Both proteins are also retained on stalled forks, where they promote fork processing and restart. Moreover, MRE11 phosphorylation and localization at replication factories are progressively lost upon CDC7 inhibition. Finally, CDC7 activity at reversed forks is required for their pathological MRE11-dependent degradation in BRCA2-deficient cells. Thus, upon replication interference CDC7 is a key regulator of fork progression, processing and integrity. These results highlight a dual role for CDC7 in replication, modulating both initiation and elongation steps of DNA synthesis, and identify a key intervention point for anticancer therapies exploiting replication interference.Graphdiyne (GDY) exhibited unique properties of highly conjugated π system, conformably distributed pores, and direct bandgap. This encouraged multidisciplinary research groups to investigate its application in energy conversion and storage, catalysts, electronic devices, sensing and separation. In this Minireview, we present the achievements of synthesis strategies for small-molecule diyne structures (graphdiyne substructure), 1D nanoribbons and 2D graphdiyne. These studies may help future investigation of the intrinsic structure-related properties of graphdiyne and synthesis methodology for the future developments of graphdiyne related 2D carbon materials.The critical role of neuroinflammation in favoring and accelerating the pathogenic process in Alzheimer's disease (AD) increased the need to target the cerebral innate immune cells as a potential therapeutic strategy to slow down the disease progression. In this scenario, mesenchymal stem cells (MSCs) have risen considerable interest thanks to their immunomodulatory properties, which have been largely ascribed to the release of extracellular vesicles (EVs), namely exosomes and microvesicles. Indeed, the beneficial effects of MSC-EVs in regulating the inflammatory response have been reported in different AD mouse models, upon chronic intravenous or intracerebroventricular administration. In this study, we use the triple-transgenic 3xTg mice showing for the first time that the intranasal route of administration of EVs, derived from cytokine-preconditioned MSCs, was able to induce immunomodulatory and neuroprotective effects in AD. MSC-EVs reached the brain, where they dampened the activation of microglia cells and increased dendritic spine density. MSC-EVs polarized in vitro murine primary microglia toward an anti-inflammatory phenotype suggesting that the neuroprotective effects observed in transgenic mice could result from a positive modulation of the inflammatory status. The possibility to administer MSC-EVs through a noninvasive route and the demonstration of their anti-inflammatory efficacy might accelerate the chance of a translational exploitation of MSC-EVs in AD.Background Patient involvement in interprofessional education (IPE) is a new approach in fostering person-centeredness and collaborative competencies in undergraduate students. We developed the Patient As a Person (PAP-)module to facilitate students in learning from experts by experience (EBEs) living with chronic conditions, in an interprofessional setting. This study aimed to explore the experiences of undergraduate students, EBEs and facilitators with the PAP-module and formulate recommendations on the design and organization of patient involvement in IPE. Methods We collected data from students, EBEs and facilitators, through eight semi-structured focus group interviews and two individual interviews (N = 51). The interviews took place at Maastricht University, Zuyd University of Applied Sciences and Regional Training Center Leeuwenborgh. Conventional content analysis revealed key themes. Results Students reported that learning from EBEs in an interprofessional setting yielded a more comprehensive approach and made them empathize with EBEs. Facilitators found it challenging to address multiple demands from students from different backgrounds and diverse EBEs. EBEs were motivated to improve the person-centredness of health care and welcomed a renewed sense of purpose. Conclusions This study yielded six recommendations (a) students from various disciplines visit an EBE to foster a comprehensive approach, (b) groups of at least two students visit EBEs, (c) students may need aftercare for which facilitators should be receptive, (d) EBEs need clear instruction on their roles, (e) multiple EBEs in one session create diversity in perspectives and (f) training programmes and peer-to-peer sessions for facilitators help them to interact with diverse students and EBEs.SrBPO5 Eu2+ -Eu3+ phosphors were synthesized using a conventional solid self-reduction reaction in an air atmosphere. Samples were characterized using thermogravimetry analysis (TGA), differential scanning calorimetry (DSC), X-ray diffraction (XRD), Fourier transform infrared (FTIR) spectra, fluorescence spectra and Commission International de l'Eclairage (CIE) data. The results of TGA and DSC showed that the raw materials could completely react at 1000°C. FTIR spectra and XRD results displayed that europium ions of different concentrations do not effect the structure of the hosts. Fluorescence spectra displayed that europium ions exist in bivalent and trivalent forms, and that the emission peak at 403 nm was attributed to the typical 5d-4f transition for Eu2+ ; 597 nm and 620 nm emissions were assigned to the characteristic transitions of 5 D0 -7F1, 2 for Eu3+ . CIE results depicted that the colour tone of the phosphors could be macro-controlled from blue to purple by controlling the doping amount of Eu3+ .Therefore, relative luminescence intensity between Eu2+ and Eu3+ could be adjusted by controlling the doping concentration of europium to tune the luminescence colour of SrBPO5 .Intestinal epithelial cells (IECs) are not only responsible for the digestion and absorption of dietary substrates but also function as a first line of host defense against commensal and pathogenic luminal bacteria. Disruption of the epithelial layer causes malnutrition and enteritis. Rab6 is a small GTPase localized to the Golgi, where it regulates anterograde and retrograde transport by interacting with various effector proteins. Here, we generated mice with IEC-specific deletion of Rab6a (Rab6a∆IEC mice). While Rab6aΔIEC mice were born at the Mendelian ratio, they started to show IEC death, inflammation, and bleeding in the small intestine shortly after birth, and these changes culminated in early postnatal death. We further found massive lipid accumulation in the IECs of Rab6a∆IEC neonates. In contrast to Rab6a∆IEC neonates, knockout embryos did not show any of these abnormalities. Lipid accumulation and IEC death became evident when Rab6a∆IEC embryos were nursed by a foster mother, suggesting that dietary milk-derived lipids accumulated in Rab6a-deficient IECs and triggered IEC death. These results indicate that Rab6a plays a crucial role in regulating the lipid transport and maintaining tissue integrity.
