Metallo-base pairs have been extensively utilized in many research fields, including genetic code extension, novel therapeutics development, and various nanodevice designs. Compared to other cations, AgI is more flexible in pairing with natural base pairs. Herein, we present a DNA structure containing two C-AgI-C pairs and one first time reported G-AgI-G pair in a short 8mer DNA strand. This structure not only discloses the detailed insights into these AgI-base pairing patterns in DNA, but also represents the first nonhelical DNA structure driven by the heavy metal ions, further contributing to the structural diversity of DNA...

BACKGROUND: Hemophagocytic lymphohistiocytosis (HLH) causes multiple organ dysfunction frequently leading to intensive care unit (ICU) referral and/or death. We report on a series of critically ill adult patients treated with a non-etoposide-based regimen including interleukin 1 antagonist anakinra, intravenous immunoglobulin (IVIG), and/or corticosteroids (CS) for HLH. METHODS: Eight adult (≥18 years) ICU patients having received treatment with anakinra ± IVIG ± CS for HLH between March 2014 and March 2016 at a large tertiary care university hospital (Medical University of Vienna, Vienna, Austria) were retrospectively analyzed...

During recent years, knowledge gaps on drinking water-related gastrointestinal illness have been identified, especially for non-epidemic cases. Pathogen contamination of drinking water during distribution has been suggested to contribute to these cases, but the risk factors are not yet fully understood. During 2014-2015, we conducted an epidemiological study in five municipalities in Sweden, to assess whether incidents in the drinking water distribution system influence the risk of gastrointestinal illness...

Various water-soluble substances are known as anti-ice nucleating agents (anti-INAs), which inhibit heterogeneous ice nucleation initiated by ice nucleating agents (INAs). Among them, several surfactants are reportedly effective as anti-INAs especially against silver iodide (AgI), which is a typical inorganic INA that induces heterogeneous ice nucleation at relatively high temperatures. In this study, the anti-ice nucleating activities of seven surfactants were examined in emulsified surfactant solutions containing AgI particles...

Canadian Inuit have often reported concerns about the quality of their municipal drinking water; research has also shown that some Inuit communities experience some of the highest incidence rates of self-reported acute gastrointestinal illness (AGI) in Canada and globally. The goal of this thesis research was to investigate drinking water perceptions and consumption patterns, as well as water contamination and potential associations with AGI in the Inuit community of Rigolet, Canada. Three census cross-sectional surveys captured data on AGI, drinking water, and water storage (2012-2014); additionally, bacterial contamination of household drinking water was assessed alongside the 2014 survey...

Ice accumulation hinders the performance of, and poses safety threats for infrastructure both on the ground and in the air. Previously, rationally designed superhydrophobic surfaces have demonstrated some potential as a passive means to mitigate ice accretion; however, further studies on material solutions that reduce impalement and contact time for impacting supercooled droplets (high viscosity) and can also repel droplets that freeze during surface contact are urgently needed. Here we demonstrate the collaborative effect of substrate flexibility and surface micro/nanotexture on enhancing both icephobicity and the repellency of viscous droplets (typical of supercooled water)...

To develop a strong HIV specific T-cell response, the HIV-1 Tat and Nef regulatory proteins have been known as attractive antigenic candidates in vaccine design. A peptide transduction domain of Tat (48-60 aa) could act to deliver other therapeutic molecules into different cells. In this line, several cell-penetrating peptides (CPPs) have been designed to transfer DNA, siRNA, polypeptides and proteins into cells through non-covalent approach such as CADY and PEP families. Some studies showed that the endogenous adjuvants including heat shock protein Gp96 could stimulate antigen-specific T cell immune responses...

BACKGROUND: Aortic graft infection (AGI) is a rare complication following reconstructive aortic surgery, yet it represents a significant source of morbidity and mortality. There is no consensus regarding the optimal surgical management, due in part to the small cohorts of patient reports. Pedicled muscle or omental flap coverage of AGI has been shown to improve outcomes, making them a valuable consideration in the treatment algorithm. Thus, we aim to compile and evaluate cases of autologous vascularized tissue (AVT) in the treatment of infected aortic grafts, summarizing location specific trends, treatments, and outcomes...

Cognitive neuropsychology (CN) has had an immense impact on the understanding of the normal cognitive processes underlying reading, spelling, spoken language comprehension and production, spatial attention, memory, visual perception, and orchestration of actions, through detailed analysis of behavioural performance by neurologically impaired individuals. However, there are other domains of cognition and communication that have rarely been investigated with this approach. Many cognitive neuropsychologists have extended their work in language, perception, or attention by turning to functional neuroimaging or lesion-symptom mapping to identify the neural mechanisms underlying the cognitive mechanisms they have identified...

The understanding of the cell biological processes underlying development and regeneration of oral tissues leads to novel regenerative approaches. Over the past years, knowledge on key roles of the hypoxia-based response has become more profound. Based on these findings, novel regenerative approaches for dentistry are emerging, which target cellular oxygen sensors. These approaches include hypoxia pre-conditioning and pharmacologically simulated hypoxia. The increase in studies on hypoxia and hypoxia-based strategies in regenerative dentistry highlights the growing attention to hypoxia's role in regeneration and its underlying biology, as well as its application in a therapeutic setting...
