Optimization of experimental and computational processes to study mitochondrial trafficking and metabolic biomarkers

Background: The complex polarity of neurons requires specialized mechanisms to allocate sufficient number of mitochondria to neurites and synapses to control local calcium and ATP levels. Deficits in trafficking are directly linked to neurodegeneration. Our objective is to demonstrate that alterations of mitochondrial spatial location and metabolism are interconnected and can lead to point-of-no-r

Sustained and controlled delivery of doxorubicin from an in-situ setting biphasic hydroxyapatite carrier for local treatment of a highly proliferative human osteosarcoma

Doxorubicin (DOX) is a cornerstone drug in the treatment of osteosarcoma. However, achieving sufficient concentration in the tumor tissue after systemic administration with few side effects has been a challenge. Even with the most advanced nanotechnology approaches, less than 5% of the total administered drug gets delivered to the target site. Alternatives to increase the local concentration of DO

Unconventional oil and gas development and ambient particle radioactivity

Unconventional oil and natural gas development (UOGD) expanded extensively in the United States from the early 2000s. However, the influence of UOGD on the radioactivity of ambient particulate is not well understood. We collected the ambient particle radioactivity (PR) measurements of RadNet, a nationwide environmental radiation monitoring network. We obtained the information of over 1.5 million w

Exposure to Air Pollution and Particle Radioactivity With the Risk of Ventricular Arrhythmias

BACKGROUND: Individuals are exposed to air pollution and ionizing radiation from natural sources through inhalation of particles. This study investigates the association between cardiac arrhythmias and short-term exposures to fine particulate matter (particulate matter ≤2.5 µm aerodynamic diameter; PM2.5) and particle radioactivity.METHODS: Ventricular arrhythmic events were identified among 176 p

Short-term ambient particle radioactivity level and renal function in older men: Insight from the Normative Aging Study

BACKGROUND: Whole-body and thoracic ionizing radiation exposure are both associated with the development of renal dysfunction. However, whether low-level environmental radiation from air pollution affects renal function remains unknown.OBJECTIVES: We investigated the association of particle radioactivity (PR) with renal function defined by the estimated glomerular filtration rate (eGFR) and chroni

The trelleborg constructors

This text builds on a manuscript written for a lecture at the Trelleborg Museum in Scania. At the museum one can read that Harald Bluetooth built the ring fortress, just like all the other Trelleborg forts, but is this so? This article looks at the datings, finds and surroundings of the East Danish trelleborg forts and presents another interpretation. A strong aristocracy with an interest in trade

Analyses of registry data of patients with anti-GBM and antineutrophil cytoplasmatic antibody-associated (ANCA) vasculitis treated with or without therapeutic apheresis

Therapeutic apheresis (TA) as a treatment for antibody-associated vasculitis (AAV) was questioned by the PEXIVAS although the MEPEX study favored TA. The aim of this study was to evaluate the efficacy of TA to improve renal function in patients consecutively included in the WAA-apheresis registry versus patients not treated with TA. Materials and methods: Included were 192 patients that suffered f

Entire functions arising from trees

Given any infinite tree in the plane satisfying certain topological conditions, we construct an entire function f with only two critical values ±1 and no asymptotic values such that f−1([−1, 1]) is ambiently homeomorphic to the given tree. This can be viewed as a generalization of the result of Grothendieck (see Schneps (1994)) to the case of infinite trees. Moreover, a similar idea leads to a new

Multidimensional Incongruence and Vote Switching in Europe

Does ideological incongruence hurt parties in elections? Research on the representational relationship between parties and voters suggests that ideological congruence can boost a party’s electoral prospects. However, while the mechanism is at the individual-level, most of the literature focuses on the party-level. In this article, we develop a set of hypotheses based on a multi-issue conception of

Tracking 14C-Labeled Organic Micropollutants to Differentiate between Adsorption and Degradation in GAC and Biofilm Processes

Granular activated carbon (GAC) filters can be used to reduce emissions of organic micropollutants via municipal wastewater, but it is still uncertain to which extent biological degradation contributes to their removal in GAC filters. 14C-labeled organic micropollutants were therefore used to distinguish degradation from adsorption in a GAC-filter media with associated biofilm. The rates and exten

A widespread toxin−antitoxin system exploiting growth control via alarmone signaling

Under stressful conditions, bacterial RelA-SpoT Homolog (RSH) enzymes synthesize the alarmone (p)ppGpp, a nucleotide second messenger. (p)ppGpp rewires bacterial transcription and metabolism to cope with stress, and, at high concentrations, inhibits the process of protein synthesis and bacterial growth to save and redirect resources until conditions improve. Single-domain small alarmone synthetase

What is the research impact of (the ideal of) scientific truth?

This conceptual paper addresses how the emergent impact agenda is slowly but surely changing the normative framework of modern science. In order to understand such a cultural shift, we draw a chronology around the evaluation regime of research impact and identify a causal mechanism that changes the disciplinary structure of the research ecosystem. We draw upon a sociological model of scientific kn

Ambulance clinicians’ attitudes to older patients’ self-determination when the patient has impaired decision-making ability: A Delphi study

ObjectiveThe proportion of older people is increasing and reflects in the demand on ambulance services (AS). Patients can be more vulnerable and increasingly dependent, especially when their decision-making ability is impaired. Self-determination in older people has a positive relation to quality of life and can raise ethical conflicts in AS. Hence, the aim of this study was to empirically explore

Developing shared languages : The fundamentals of mutual learning and problem solving in transdisciplinary collaboration

This issue of the AILA Review focuses on transdisciplinarity as the key to developing shared languages in and across domains and professional settings. The relationship and collaboration between researchers and practitioners have long been discussed within and across applied sciences and theoretical disciplines, mainly in the framework of transdisciplinarity (see AILA Review 31, 2018, for a recent

Assessing the potential and hydrological usefulness of the CHIRPS precipitation dataset over a complex topography in Pakistan

This study evaluates the spatial and temporal performance of the Climate Hazard Group InfraRed Precipitation Satellite (CHIRPS) against Tropical Rainfall Measuring Mission (TRMM) Multi-Satellite Precipitation Analysis (TMPA) 3B42/3B43 v. 7 and Global Precipitation Measurement (GPM)-based Integrated Multi-Satellite Retrievals for GPM (IMERG V06), from 2000 to 2013. Several statistical metrics were

An ancient family of SelB elongation factor-like proteins with a broad but disjunct distribution across archaea

Background: SelB is the dedicated elongation factor for delivery of selenocysteinyl-tRNA to the ribosome. In archaea, only a subset of methanogens utilizes selenocysteine and encodes archaeal SelB (aSelB). A SelB-like (aSelBL) homolog has previously been identified in an archaeon that does not encode selenosysteine, and has been proposed to be a pyrrolysyl-tRNA-specific elongation factor (EF-Pyl).
