Functional outcomes are central to cancer care decision-making by older adults.

To assess the long-term functional outcomes of older adults after a resection for cancer using time at home as the measure.

This population-based cohort study was conducted in Ontario, Canada, using the administrative databases stored at ICES (formerly the Institute for Clinical Evaluative Sciences). The analysis included adults 70 years or older with a new diagnosis of cancer between January 1, 2007, and December 31, 2017, who underwent a resection 90 days to 180 days after the diagnosis. Patients were followed up until and censored at the date of death, date of last contact, or December 31, 2018.

The main outcome was time at home, dichotomized as high time at home (defined as ≤14 institution days annually) and low time at home (defined as >14 institution days) during the 5 years after surgical cancer treatment. Time-to-event analyses with Kaplan-Meier methods and multivariable Cox proportional hazards regression modeltional outcomes in this population. The oldest adults and those with preoperative frailty and material deprivation appeared to be the most vulnerable to low time at home, and efforts to optimize and manage expectations about surgical outcomes can be targeted for this population; this information is important for patient counseling regarding surgical cancer treatment and for preparation for postoperative recovery.Coraciiformes contains more than 200 species with great differences on external morphology and life-style. The evolutionary relationships within Coraciiformes and the phylogenetic placement of Coraciiformes in Aves are still questioned. Mitochondrial genome (mitogenome) sequences are popular markers in molecular phylogenetic studies of birds. This study presented the genome characteristics of three new mitogenomes in Coraciiformes and explored the phylogenetic relationships among Coraciiformes and other five related orders with mitogenome data of 30 species. The sizes of three mitogenomes were 17,383 bp (Alcedo atthis), 17,892 bp (Halcyon smyrnensis) and 17,223 bp (Megaceryle lugubris). Each mitogenome contained one control region and 37 genes that were common in vertebrate mitogenomes. The organization of three mitogenomes was identical to the putative ancestral gene order in Aves. Among 13 available Coraciiform mitogenomes, 12 protein coding genes showed indications of negative selection, while the MT-ND6 presented sign of positive selection or relaxed purifying selection. The phylogenetic results supported that Upupidae and Bucerotidae should be separated from Coraciiformes, and that Coraciiformes is more closely related to Piciformes than to Strigiformes, Trogoniformes and Cuculiformes. Our study provide valuable data for further phylogenetic investigation of Coraciiformes.Cartilage injury is very common and results in considerable pain and osteoarthritis. Owing to its low self-renewal capability, cartilage regeneration is still a great challenge for clinicians. Stem cell therapy has been treated as the most promising treatment for cartilage regeneration in recent decades. However, increasing concerns about the potential biosafety of stem cell products such as immune rejection and neoplastic transformation restrict their further application in clinic. Herein, biomimetic stem cell membrane-disguised nanovehicles without biosafety risks are designed and prepared for cartilage regeneration. In this study, based on the disguise of the natural bone marrow mesenchymal stem cell (BMSC) membrane, Kartogenin (KGN) as a drug for cartilage regeneration was encapsulated into Fe3O4 nanoparticles as the core of biomimetic stem cell nanovehicles. In the core-shell structure of biomimetic stem cell nanovehicles, the fabricated KGN-loaded BMSC membrane-disguised Fe3O4 nanoparticles (KGN-MNPs) showed a stable hybrid structure with a uniform size and morphology in the physiological environments. Moreover, the prepared KGN-MNPs exhibited excellent biocompatibility when disguised with the natural membrane of BMSCs and good biosafety by eliminating the nuclei of BMSCs. In a cartilage defect rat model, compared with pure KGN, the intra-articularly injected KGN-MNPs were capable of regenerating an integrated organized structure with a layer of hyaline-like cartilage in a shorter time due to the retained natural activities of the BMSC membrane. In a word, KGN-MNPs as one kind of our designed biomimetic stem cell nanovehicles enable rapid and high quality cartilage regeneration, and provide a novel and standardized strategy for stem cell therapy in the future.Heparan sulfate (HS) and heparin are sulfated polysaccharides exhibiting diverse physiological functions. HS 6-O-sulfotransferase (6-OST) is a HS biosynthetic enzyme that transfers a sulfo group to the 6-OH position of glucosamine to synthesize HS with desired biological activities. Chemoenzymatic synthesis is a widely adopted method to obtain HS oligosaccharides to support biological studies. However, this method is unable to synthesize all possible structures due to the specificity of natural enzymes. Here, we report the use of an engineered 6-OST to achieve fine control of the 6-O-sulfation. Unlike wild type enzyme, the engineered 6-OST only sulfates the non-reducing end glucosamine residue. Utilizing the engineered enzyme and wild type enzyme, we successfully completed the synthesis of five hexasaccharides and one octasaccharide differing in 6-O-sulfation patterns. We also identified a hexasaccharide construct as a new anticoagulant drug candidate. Our results demonstrate the feasibility of using an engineered HS biosynthetic enzyme to prepare HS-based therapeutics.A new hybrid organic-inorganic film, tincone, was developed by using molecular layer deposition (MLD), and exhibited high electrochemical activity toward Li storage. The self-limiting growth behavior, high uniformity on various substrates and good Li-storage performance make tincone a very promising new anode material for 3D microbatteries.We investigated the cryptic red chromophore, accompanying the blue S3˙- radical in ultramarine pigments, which usually was tentatively assigned to an unspecified isomer of either neutral S4 or ionic S4˙- species. To reveal its identity, we performed the first systematic density functional studies on periodic and large cluster models of red ultramarines, considering several S4/S4˙- isomers embedded in aluminosilicate cages. Cytidine For both neutral and charged tetrasulfides the most stable confined isomer is the planar C2v one. The only plausible candidate for the red chromophore among the tetrasulfur species is the planar C2v isomer of the neutral S4 molecule, which, apart from being thermodynamically preferable, strongly absorbs green light and its vibrational modes match very well with the available Raman data. The C2v-S4˙- radical, if present at all in red ultramarines, could be identified by strong absorption in the near infrared region and possibly by the slightly larger isotropic value of the g tensor than that of the S3˙- radical.
