Eastern boundary upwelling systems (EBUS) are among the most productive marine ecosystems on Earth. The production of organic material is fueled by upwelling of nutrient-rich deep waters and high incident light at the sea surface. However, biotic and abiotic factors can modify surface production and related biogeochemical processes. Determining these factors is important because EBUS are considere
A high-throughput method for the fabrication of ordered arrays of Au nanoparticles is presented. It is based on pulsed electrodeposition into porous anodic alumina templates. In contrast to many synthesis routes, it is cyanide-free, prior separation of the alumina template from the aluminium substrate is not required, and the use of contaminating surfactants/capping agents often found in colloidal
Objective: To compare the concentrations of high mobility group box 1 protein (HMGB1) and S100A8/A9 in synovial fluid between patients with knee injuries and osteoarthritis (OA), and knee healthy subjects. To investigate associations of alarmin levels with different joint injuries and with biomarkers of inflammation, Wnt signaling, complement system, bone and cartilage degradation. Methods: HMGB1
Background Systemic lupus erythematosus (SLE) is a complex disease characterized by autoimmunity toward apoptotic cells, excessive amounts of circulating immune complexes, and complement activation. A decreased platelet size has been observed in SLE and their nonhemostatic functions may play an active role in the disease. The main objective of this study was to find clues that could explain their
A novel process configuration was designed to increase biofilm growth in tertiary moving bed biofilm reactors (MBBRs) by providing additional substrate from primary treated wastewater in a sidestream reactor under different redox conditions in order to improve micropollutant removal in MBBRs with low substrate availability. This novel recirculating MBBR was operated on pilot scale for 13 months, a
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
This paper reports on a case study of a quadrilingual child, Stefan, born and raised in Sweden and exposed to four languages before his first birthday: English, French, Russian and Swedish. We examine his vocabularies in these languages by the Cross-Linguistic Lexical Tasks (Haman, Łuniewska, & Pomiechowska, 2015), designed to measure vocabulary in monolingual and multilingual children. Stefan
The aim of this theoretical paper is to critically reflect on the ethical and methodological issues that arose during a study that observed nurses’ care-giving in an intensive care unit setting. The authors critically discuss the methodological and ethical issues as well as the practical realities that were encountered when evaluating a complex intervention using unstructured qualitative observati
Although remarkable progress has been achieved in reducing hunger and poverty and improving people’s health in the past couple of decades, humanity still faces considerable socio-economic and sustainability challenges. Ensuring sustainable access to safe and sufficient water, improved sanitation facilities, clean energy sources and healthy food is a necessary requirement for ending hunger and pove
Penetration of the viral genome into a host cell nucleus is critical for initiation of viral replication for most DNA viruses and a few RNA viruses. For herpesviruses, viral DNA ejection into a nucleus occurs when the capsid docks at the nuclear pore complex (NPC) basket with the correct orientation of the unique capsid portal vertex. It has been shown that capsid vertex-specific component (CVSC)
In 1899, the British colonialist Cecil Rhodes went to Berlin to negotiate about his fantastical ‘Cape-to-Cairo’ telegraph and railway scheme with his former nemesis, the German emperor Wilhelm II. Why did this initiative of Rhodes, who was held responsible for the disastrous Jameson Raid and no longer occupied any official position, receive so much coverage and legitimacy in the international pres
Objective: Blindness and low vision have severe effects on individuals' quality of life and socioeconomic cost; a main contributor of which is a prevalent and acutely decreased mobility level. To alleviate this, numerous technological solutions have been proposed in the last 70 years; however, none has become widespread. Method: In this paper, we introduce the vision-to-audio, super-scale sensory
The barrier function of the skin mainly relies on its outermost layer, the stratum corneum (SC), which is a lipid-protein composite biomaterial. In addition, SC contains a mixture of small polar compounds, the natural moisturizing factor (NMF). Most of the NMF components are solid at ambient relative humidities (RHs). We herein raise the question of what the effects of adding a mixture of chemical
Domestic mallards (Anas platyrhynchos domesticus) are traditionally used as a model to investigate infection dynamics and immune responses to low pathogenic avian influenza viruses (LPAIVs) in free-living mallards. However, it is unclear whether the immune response of domestic birds reflects the response of their free-living counterparts naturally exposed to these viruses. We investigated the exte
Research on younger patients with hip fractures is limited. This study adds knowledge on patient and injury characteristics, and DXA was investigated at the time of the fracture. Risk factors for osteoporosis and fractures were numerous among young patients, and osteoporosis was markedly more prevalent than in the general population.INTRODUCTION: Knowledge on younger patients with hip fractures is
Purpose: Long-term follow-up (LTFU) care is essential to optimise health outcomes in childhood cancer survivors (CCS). We aimed to assess the impact of the COVID-19 pandemic on LTFU services and providers. Methods: A COVID-19 working group within the International Late Effects of Childhood Cancer Guideline Harmonization Group (IGHG) distributed a questionnaire to LTFU service providers in 37 count
PURPOSE: To report practice patterns of corneal transplantation in Europe. SETTING: Corneal clinics in 10 European member states (MS), the United Kingdom, and Switzerland. DESIGN: Multinational registry study. METHODS: Corneal transplant procedures registered in the European Cornea and Cell Transplantation Registry were identified. Preoperative donor and recipient characteristics, indication and r
On the Internet, many commentary styles take place on various forums, and abuse is not uncommon. We investigated the personality traits related to individuals’ behaviors on Internet forum posting. The Dark Short Tetrad (SD4) were used to predict (N = 212) three types of commentary styles: Trolling (malicious posting), Lurking (reading/not posting) and Posting (reading/posting). The results showed
ObjectiveThis paper examines a previously neglected phenomenon in doctor-patient interaction studies, i.e. the achievement of mutual disengagement—a specific state of coordination, in which participants suspend reciprocal gaze and turn into separate axes of involvement. In the specialized setting of the oncology visit, which we consider in this study, mutual disengagement is linked to important ta
