Soil nitrate and ammonium: Litter Quality and Landscape Controls of Decomposition

This experiment was established in November of 1990. It involved placing over a thousand preweighed and labeled oak and birch dowels in the field across the Cedar Creek landscape. The purpose is to measure the decomposition potential using a uniform common substrate across Cedar Creeks broad range of ecosystems. Each of the 27 sites have 11 above and 11 belowground dowels of birch and the same number of red oak. This allows for two samples the first year and one per year thereafter for 10 years. Each dowel is 12.7cm long and 1.27cm in diameter. Each dowel is preweighed and tagged. Belowground dowels are driven into the ground vertically and tethered to two pieces of rebar (birch on one, oak on the other) located about a meter apart. Aboveground dowels are laid on top of existing litter and are tethered to the rebars. Resin bags are tethered to the rebars and buried in the upper soil (ca. 5cm). Replicate sets of dowels and ion exchange resin bags (to measure N availability) were placed in 9 grassland, 9 forest, and 9 wetland sites. All 27 sites are in or adjacent to already established LTER plots. The first samples were collected in May 1991. On May 5, 1995, a wildfire burned completely through field B where some of experiment 88 was located.

Quality of advertisements for prescription drugs in family practice medical journals published in Australia, Canada, and the United States with different regulatory controls: a cross-sectional study

OBJECTIVE: To assess if different forms of regulation lead to differences in the quality of journal advertisements. DESIGN: Cross-sectional study. PARTICIPANTS: Thirty advertisements from family practice journals published from 2013-2015 were extracted for three countries with distinct regulatory pharmaceutical promotion systems: Australia, Canada, and the United States (US). PRIMARY AND SECONDARY OUTCOME MEASURES: Advertisements under each regulatory system were compared concerning three domains: information included in the advertisement, references to scientific evidence, and pictorial appeals and portrayals. An overall ranking for advertisement quality among countries was determined using the first two domains as the information assessed has been associated with more appropriate prescribing. RESULTS: Advertisements varied significantly for number of claims with quantitative benefit (Australia: 0.0 (0.0-3.0); Canada: 0.0 (0.0-5.0); US: 1.0 (0.0-6.0); p=0.01); statistical method used in reporting benefit (RRR, ARR, and NNT) (Australia: 6.7%, n=2; Canada: 10.0%, n=3; US: 36.6%, n=11; p=0.02); mention of adverse effects, warnings, or contraindications (Australia: 13.3%, n=4; Canada: 23.3%, n=7; US: 53.3%, n=16; p=0.002); equal prominence between safety and benefit information (Australia: 25.0%, n=1; Canada: 28.6%, n=2; US: 75.0%, n=12; p=0.04); and methodologic quality of references score (Australia: 0.4150 (0.25-0.70); Canada: 0.25 (0.00-0.63); US: 0.25 (0.00-0.75); p<0.001). The US ranked first, Canada second, and Australia third for overall quality of journal advertisements. Significant differences for humor appeals (Australia: 3.3%, n=1; Canada: 13.3%, n=4; US: 26.7%, n=8; p=0.04), positive emotional appeals (Australia: 26.7%, n=8; Canada: 60.0%, n=18; US: 50.0%, n=15; p=0.03), social approval portrayals (Australia: 0.0%, n=0; Canada: 0.0%, n=0; US: 10.0%, n=3; p=0.04), and lifestyle or work portrayals (Australia: 43.3%, n=13; Canada: 50.0%, n=15; US: 76.7%, n=23; p=0.02) were found among countries. CONCLUSIONS: <a name="_Hlk34742358">Different regulatory systems influence journal advertisement quality concerning all measured domains. </a>However, differences may also be attributed to other regulatory, legal, cultural, or health system factors unique to each country.

Data from: Litter conversion into detritivore faeces reshuffles the quality control over C and N dynamics during decomposition

1. In many terrestrial ecosystems, detritivorous soil organisms ingest large amounts of leaf litter returning most of it to the soil as faeces. Such conversion of leaf litter into faeces may stimulate decomposition by increasing the surface area available for microbial colonization. Yet, experimental support for either the outcome or the mechanism of these conversion effects is lacking. 2. Based on the hypothesis that the identity of plant species from which leaf litter is transformed into faeces has a critical role in how faeces decomposition proceeds, we collected faeces of the widely abundant millipede Glomeris marginata fed with leaf litter from seven distinct tree species. We compared the physical and chemical characteristics and the rates of carbon (C) and nitrogen (N) loss between litter and faeces. 3. We found that after 100 days of exposure under controlled conditions, C loss was on average higher in faeces (40%) than in litter (26.6%), with a significant increase for six out of the seven species. Concurrently, N dynamics switched from a net immobilisation (7.7%) in litter to a net release (14.6%) in faeces, with a significant increase for five out of the seven species. 4. Litter conversion into faeces generally homogenised differences in physical and chemical characteristics among species. Despite such homogenisation, variability in rates of faeces C and N loss among species was similar compared to leaf litter, but correlated with a different set of traits. Specifically, faecal pellet C loss was positively related to compaction (decreased specific area and increased density of faecal pellets), and both C and N loss from faecal pellets were positively related to fragmentation (increased specific area and perimeter of particles within faecal pellets). 5. We conclude that litter fragmentation and compaction into detritivore faecal pellets leads to substantially enhanced decomposition, with a particularly strong impact on N dynamics that changed from immobilisation to net release depending on litter species. Moreover, litter quality control on decomposition is reshuffled by litter conversion into faeces. In ecosystems with high detritivore abundance, this so far largely overlooked pathway of organic matter turnover may strongly affect ecosystem C and N cycling.

Data from: Quality control processes in allografting: a twenty-year retrospective review of a hospital-based bone bank in Taiwan

Musculoskeletal allografts are now commonly used. To decrease the potential risks of transmission of pathogenic bacteria, fungi, or viruses to the transplant recipients, certain issues regarding the management of patients who receive contaminated allografts need to be addressed. We aimed to clarify the incidence and extent of disease transmission from allografts by analyzing the allografting procedures performed in the bone bank of our hospital over the past 20 years. We retrospectively reviewed the data from our allograft registry center on 3979 allografts that were implanted in 3193 recipients throughout a period of two decades, from July 1991 to June 2011. The source of the allografts, results of all screening tests, dates of harvesting and implantation, and recipients of all allografts were checked. With the help of the Center for Infection Control of our hospital, a strict prospective, hospital-wide, on-site surveillance was conducted, and every patient with healthcare-associated infection was identified. Fisher's exact test was used to compare the infection rate between recipients with sterile allografts and those with contaminated allografts. The overall discard and infection rates were, respectively, 23% and 1.3% in the first decade (1991–2001); and 18.4% and 1.25% in the second decade (2001–2011). The infection rate of contaminated allograft recipients was significantly higher than that of sterile allograft recipients (10% vs. 1.15%, P < 0.01) in the second decade. Both infection and discard rates of our bone bank are comparable with those of international bone banks. Strict allograft processing and adequate prophylactic use of antibiotics are critical to prevent infection and disease transmission in such cases.

Molecular basis of MHC I quality control in the peptide loading complex

Major histocompatibility complex class I (MHC I) molecules are central to adaptive immunity. Their assembly, epitope selection, and antigen presentation are controlled by the MHC I glycan through a sophisticated network of chaperones and modifying enzymes. However, the mechanistic integration of the corresponding processes remains poorly understood. Here, we determine the multi-chaperone-client interaction network of the peptide loading complex (PLC) and report PLC editing module structure by cryo-electron microscopy at 3.7 Å resolution. Combined with epitope-proofreading studies of the PLC in near-native lipid environment, these data show that peptide-receptive MHC I molecules are stabilized by multivalent chaperone interactions including the calreticulin-engulfed mono-glucosylated MHC I glycan, which only becomes accessible for processing by α-glucosidase II upon loading of optimal epitopes. Our work reveals allosteric coupling between peptide-MHC I assembly and glycan processing. This inter-process communication defines the onset of an adaptive immune response and provides a prototypical example of the tightly coordinated events in endoplasmic reticulum quality control.
