An ongoing outbreak of pneumonia associated with the severe acute respiratory coronavirus 2 (SARS-CoV-2) started in Wuhan, China, with cases now confirmed in multiple countries. The clinical course of patients remains to be fully characterized, clinical presentation ranges from asymptomatic infection to acute respiratory distress syndrome and acute renal failure，no pharmacological therapies of proven efficacy yet exist. We report a case of SARS-CoV-2 infection in a renal transplant recipient with excellent outcome. This case states the importance of close monitoring of the concentration of ciclosporin in patients treated with lopinavir/ritonavir, routine treatment of corticosteroid can be continued. This is a rare report of SARS-CoV-2 infection in a renal transplant recipient. Further data are needed to achieve better understanding of the impact of immunosuppressive therapy on the clinical presentation, severity and outcome of SARS-CoV-2 infections in solid organ transplant recipients.

Here the fast side chain dynamics of the 7-transmembrane helix protein sensory rhodopsin II and the beta-barrel bacterial outer membrane channel protein W have been investigated in lipid bilayers and detergent micelles by solution NMR relaxation techniques. Though of quite different topologies, both proteins are found to have a similar and striking distribution of methyl-bearing amino acid side chain motion that is independent of membrane mimetic. Salinomycin The methyl-bearing side chains of both proteins are, on average, more dynamic in the ps-ns time regime than any soluble protein characterized to date. Approximately one third of methyl-bearing side chains in both proteins exhibit extreme rotameric averaging on this timescale. Accordingly, both proteins retain an extraordinary residual conformational entropy in the folded state, which provides a counterbalance to the absence of the hydrophobic effect that normally stabilizes the folded state of water-soluble proteins. Furthermore, the large reservoir of conformational entropy that is observed provides the potential to greatly influence the thermodynamics underlying a plethora of membrane protein functions including ligand binding, allostery and signaling. © 2020 WILEY-VCH Verlag GmbH & Co.

We report on 10-year post-transplant outcomes with (group 1, n=26) and without (group 2, n=9) a functional graft. Ten-year patient and graft survival rates were 53% and 36%, respectively. Most patients were studying or working, one-third having psychiatric disorders. All patients in group 1 were weaned off parenteral nutrition with mostly normal physical growth and subnormal energy absorption. Graft histology from 15 late biopsies showed minimal abnormality. However, micronutrient deficiencies and fat malabsorption were frequent; biliary complications occurred in 4 patients among the 17 who underwent liver transplantation; median renal clearance was 87 mL/min/1.73 m2 . Four patients in group 1 experienced late acute rejection. Among the nine patients in group 2, four died after 10 years, and two developed significant liver fibrosis. Liver transplantation and the use of a three-drug regimen including sirolimus or mycophenolate-mofetil were associated with improved graft survival. Therefore, intestinal transplantation may enable a satisfactory digestive function in the long term. The prognosis of graft removal without retransplantation is better than expected. Regular monitoring of micronutrients, early psychological assessment, and use of sirolimus are recommended. This article is protected by copyright.

The NKR represents a voluntary commitment by participating transplant centers to share patients, kidneys, medical acumen, surgical skills, hospital quality, transport logistics, organ preservation, and laboratory testing; each of which is essential to facilitate successful live donor transplantation. The requirements to share kidneys within the NKR are based on real-world experience that has evolved since the inception of the consortia in 2008. This article is protected by copyright.

A myriad of catalytic asymmetric tools have been elegantly developed for the construction of BINOL and its C 2 -symmetrical derivatives possessing distinct features. Here we present a class of novel axially chiral aryl- p -quinones as platform molecules for the synthesis of non- C 2 symmetric biaryldiols. Two sets of aryl- p -quinone frameworks were synthesized with remarkable enantiocontrol by means of chiral phosphoric acid catalyzed enantioselective arylation of p -quinones via central-to-axial chirality transfer and a wide spectrum of highly functionalized non- C 2 symmetric biaryldiols were obtained with excellent enantiopurity retention. © 2020 WILEY-VCH Verlag GmbH & Co.

The purpose of the present study was to investigate tumor-infiltrating immune cells (TIICs) in the tumor microenvironment (TME), mainly the impact of TIICs and PD-L1 expression on clinical outcomes in thymic cancer. Patients with thymic carcinoma resected between 1973 and 2017 were investigated. The tissue specimens were analyzed through immunohistochemical staining to elucidate the prognostic effects of TIICs, their ratios, and PD-L1 in a preliminary cohort (n=10). The density of TIICs as well as PD-L1 expression was evaluated in intraepithelial and tumor-stromal areas on the representative whole section of tumor. The immune factors showing significant association with disease-free survival (DFS) were evaluated in the total cohort (n=42). TIICs in the preliminary population showed no significant difference between the two groups. However, CD8, CD20, CD204, FOXP3, and CD20/CD204 ratio demonstrated a tendency to act as predictive markers for recurrence.
