Proteomic analysis reveals dexamethasone rescues matrix breakdown but not anabolic dysregulation in a cartilage injury model

Objectives: In this exploratory study, we used discovery proteomics to follow the release of proteins from bovine knee articular cartilage in response to mechanical injury and cytokine treatment. We also studied the effect of the glucocorticoid Dexamethasone (Dex) on these responses.Design: Bovine cartilage explants were treated with either cytokines alone (10 ng/ml TNFα, 20 ng/ml IL-6, 100 ng/ml

Analysis of "old" proteins unmasks dynamic gradient of cartilage turnover in human limbs

Unlike highly regenerative animals, such as axolotls, humans are believed to be unable to counteract cumulative damage, such as repetitive joint use and injury that lead to the breakdown of cartilage and the development of osteoarthritis. Turnover of insoluble collagen has been suggested to be very limited in human adult cartilage. The goal of this study was to explore protein turnover in articula

Placebo comparator group selection and use in surgical trials : The aspire project including expert workshop

Background: The use of placebo comparisons for randomised trials assessing the efficacy of surgical interventions is increasingly being considered. However, a placebo control is a complex type of comparison group in the surgical setting and, although powerful, presents many challenges. Objectives: To provide a summary of knowledge on placebo controls in surgical trials and to summarise any recomme

CEACAM5, KLK6, SLC35D3, POSTN, and MUC2 mRNA Analysis Improves Detection and Allows Characterization of Tumor Cells in Lymph Nodes of Patients Who Have Colon Cancer

BACKGROUND: Lymph node metastasis is the single most important prognostic risk factor for recurrence in patients with colon cancer who have undergone curative surgery. The routine method for detecting disseminated tumor cells in lymph nodes is microscopic examination of one or a few hematoxylin and eosin-stained tissue sections by a trained pathologist. This method, however, is insensitive mainly

A sustainability index within water and wastewater management in Sweden : An evaluation of eight case studies

A sustainability index (SI) is a benchmark for guiding the activities of municipal water and wastewater (W and WS) utilities toward sustainability. The SI has been used in Sweden since 2014 as an internal benchmark management tool facilitating the strategic work of organizations. This study assesses how the SI was applied in practice by eight utilities (Orgs 1–8) from 2015 to 2019. The study was p

Variabilities and trends of rainfall, temperature, and river flow in sipi sub-catchment on the slopes of mt. Elgon, uganda

The variabilities in rainfall and temperature in a catchment affect water availability and sustainability. This study assessed the variabilities in rainfall and temperature (1981–2015) and river flow (1998–2015) in the Sipi sub-catchment on annual and seasonal scales. Observed daily rainfall and temperature data for Buginyanya and Kapchorwa weather stations were obtained from the Uganda National M

Health-Related Quality of Life in Children With Earlier Surgical Repair for Right Ventricular Outflow Tract Anomalies and the Agreement Between Children and Their Parents

Background: Children diagnosed with right ventricle outflow tract (RVOT) anomalies require surgical repair early in life, reoperations and lifelong follow-up. The aim is to comprehensively describe their health related quality of life (HRQoL) and to assess the agreement in this regard between children and parents. Methods and Results: Child- and parent-reported HRQoL was assessed in 97 children ag

Towards explaining knowledge hiding through relationship conflict, frustration, and irritability : The case of public sector teaching hospitals

Organizations grow and excel with knowledge sharing; on the other hand, knowledge hiding is a negative behavior that impedes innovation, growth, problem solving, and timely correct decision making in organizations. It becomes more critical in the case of teaching hospitals, where, besides patient care, medical students are taught and trained. We assume that negative emotions lead employees to hide

Towards making an invisible diversity visible : A study of socially structured barriers for purple collar employees in the workplace

Eunuchs and members of the transgender community are yet to be recognized as an effective human resource and this diversity in the workforce is still invisible. A tiny portion of the transgender community is employed, and they are tagged as purple collar employees. It is generally claimed that coworkers do not accept members of the transgender community in the workplace and are not willing to work

A data-driven approach to assess the risk of encountering hazardous materials in the building stock based on environmental inventories

The presence of hazardous materials hinders the circular economy in construction and demolition waste management. However, traditional environmental investigations are costly and time-consuming, and thus lead to limited adoption. To deal with these challenges, the study investigated the possibility of employing registered records as input data to achieve in situ hazardous building materials manage

Condensed Supramolecular Helices : The Twisted Sisters of DNA

Condensation of DNA helices into hexagonally packed bundles and toroids represents an intriguing example of functional organization of biological macromolecules at the nanoscale. The condensation models are based on the unique polyelectrolyte features of DNA, however here we could reproduce a DNA-like condensation with supramolecular helices of small chiral molecules, thereby demonstrating that it
