Strategies for studying bacterial adhesion in Vivo

The ultimate goal of studies on microbial adhesion is to understand what molecular interactions between the host and microbe occur in vivo and the impact of these interactions on disease processes. With this goal in mind, the problem can be approached at four levels. At the biochemical level, the host receptors at the relevant colonization site are identified; at the cell biology level, consequenc

VLA cm-wave survey of young stellar objects in the Oph A cluster : Constraining extreme UV- And X-ray-driven disk photoevaporation: A pathfinder for Square Kilometre Array studies

Observations of young stellar objects (YSOs) in centimeter bands can probe the continuum emission from growing dust grains, ionized winds, and magnetospheric activity that are intimately connected to the evolution of protoplanetary disks and the formation of planets. We carried out sensitive continuum observations toward the Ophiuchus A star-forming region, using the Karl G. Jansky Very Large Arra

Investigations of the kinetics and mechanism of reduction of a carboplatin pt(IV) prodrug by the major small-molecule reductants in human plasma

The development of Pt(IV) anticancer prodrugs to overcome the detrimental side effects of Pt(II)-based anticancer drugs is of current interest. The kinetics and reaction mechanisms of the reductive activation of the carboplatin Pt(IV) prodrug cis,trans-[Pt(cbdca)(NH3)2Cl2] (cbdca = cyclobutane-1,1-dicarboxylate) by the major small-molecule reductants in human plasma were analyzed in this work. The

The Socio-Legal Relevance of Artificial Intelligence (report)

The report draws on socio-legal theory in relation to growing concerns over fairness, accountability and transparency of societally applied artificial intelligence (AI) and machine learning. The purpose is to contribute to a broad socio-legal orientation by describing legal and normative challenges posed by applied AI. To do so, the article first analyses a set of problematic cases, e.g. image rec

Transforming development and disaster risk

This article focuses on the complex relationship between development and disaster risk. Development and disaster risk are closely linked as the people and assets exposed to risk, as well as their vulnerability and capacity, are largely determined by development processes. Transformation is key to moving from current development patterns that increase, create or unfairly distribute risks, to forms

The contribution of sense of place to social-ecological systems research : A review and research agenda

To develop and apply goals for future sustainability, we must consider what people care about and what motivates them to engage in solving sustainability issues. Sense of place theory and methods provide a rich source of insights that, like the social-ecological systems perspective, assume an interconnected social and biophysical reality. However, these fields of research are only recently beginni

Depletion of the transcriptional coactivators CREB-binding protein or EP300 downregulates CD20 in diffuse large B-cell lymphoma cells and impairs the cytotoxic effects of anti-CD20 antibodies

Monoclonal antibodies targeting CD20 are central in the treatment of B-cell lymphomas. In diffuse large B-cell lymphoma (DLBCL), inactivating mutations of the histone acetyltransferases CREB-binding protein (CBP) and EP300 are common. Moreover, knockdown of CBP in DLBCL has been shown to result in aberrant transcriptional silencing. Expression of CD20 is sensitive to epigenetic manipulation, and h

Detailed phenotyping of posterior vs. anterior circulation ischemic stroke : a multi-center MRI study

Objective: Posterior circulation ischemic stroke (PCiS) constitutes 20–30% of ischemic stroke cases. Detailed information about differences between PCiS and anterior circulation ischemic stroke (ACiS) remains scarce. Such information might guide clinical decision making and prevention strategies. We studied risk factors and ischemic stroke subtypes in PCiS vs. ACiS and lesion location on magnetic

Systematic microbial production of optically active dissolved organic matter in subarctic lake water

The ecology and biogeochemistry of lakes in the subarctic region are particularly sensitive to changes in the abundance and optical properties of dissolved organic matter (DOM). External input of colored DOM to these lakes is an extensively researched topic, but little is known about potential reciprocal feedbacks between the optical properties of DOM and internal microbial processes in the water.

Avian thermoregulation across age and seasons

Vilda djur påverkas ständigt av omgivningens temperatur som, tillsammans med ytterligare faktorer, styr många av de mönster och beteenden vi ser hos djur i naturen. Förändringar i temperatur kan till exempel påverka hur populationer och individer rör sig över tid och rum, när de väljer att fortplanta sig samt hur mycket föda som finns att tillgå. För jämnvarma djur, fåglar och däggdjur, som producAnimals constantly need to relate to prevailing environmental conditions and regulate their body temperature accordingly. Body temperature regulation in birds and mammals is inherently linked to energy expenditure and, thus, thermoregulation is a physiological mechanism that could trade-off with other costly processes, with potential long-term fitness consequences. In this thesis, I studied ecolog

Comparison of Cu salts and commercial Cu based fungicides on toxicity towards microorganisms in soil

Microbial responses to Cu pollution as a function of Cu sources (Cu salts and commercial Cu fungicides) were assessed in a soil using basal soil respiration, and bacterial and fungal community growth, as endpoints. The soil was amended with different concentrations (0–32 mmol Cu kg−1) of Cu nitrate, Cu sulfate, Bordeaux mixture and 3 types of Cu oxychloride. Cu salts decreased soil pH, while this

Favorable Pharmacokinetic Characteristics of Extended-Half-Life Recombinant Factor VIII BAY 94-9027 Enable Robust Individual Profiling Using a Population Pharmacokinetic Approach

Background: Prophylaxis with factor VIII (FVIII) should be individualized based on patient characteristics, including FVIII pharmacokinetics. Population pharmacokinetic (popPK) modeling simplifies pharmacokinetic studies by obviating the need for multiple samples. Objective: The objective of this study was to characterize the pharmacokinetics and inter-individual variability (IIV) of BAY 94-9027 i

No excess harms from sustained-release morphine : A randomised placebo-controlled trial in chronic breathlessness

Objectives: We aimed to identify and evaluate: (1) treatment-emergent adverse events (TEAE (worse or new since baseline)) and the subgroup of severe TEAEs in a placebo-controlled 7-day randomised trial of regular, low-dose, sustained-release oral morphine for chronic breathlessness and (2) clinical characteristics associated with TEAE. Methods: Safety analysis of trial data. Adults with chronic br

Following Protein Dynamics in Real Time during Crystallization

The process of protein crystallization from aqueous protein solutions is still insufficiently understood. During macroscopic crystal formation, occurring often on time scales from a few hours to several days, protein dynamics evolves on the molecular level. Here, we present a proof of concept and a framework to observe this evolving diffusive dynamics on the pico- to nanosecond time scale, associa

Temperature drives pre-reproductive selection and shapes the biogeography of a female polymorphism

Conflicts of interests between males and females over reproduction is a universal feature of sexually reproducing organisms and has driven the evolution of intersexual mimicry, mating behaviours and reproductive polymorphisms. Here, we show how temperature drives pre-reproductive selection in a female colour polymorphic insect that is subject to strong sexual conflict. These species have three fem

The strategic focus of shippers and transport providers on greening transportation

Purpose To examine the strategic focus of shippers and transport providers (TPs) in reducing the environmental impact of transportation. Research questions: 1) To what extent are the green practices related to transportation described in literature being realised in practice by shippers and TPs? 2) How do shippers and TPs prioritise transportation compared to other initiatives for greening the sup

An osteopontin-derived peptide inhibits human hair growth at least in part by decreasing fibroblast growth factor-7 production in outer root sheath keratinocytes

Background: Given that unwanted hair growth (hirsutism, hypertrichosis) can cause major psychological distress, new pharmacological treatment strategies with safe and effective hair growth inhibitors that do not destroy the hair follicle (HF) and its stem cells need to be developed. Objectives: To establish if osteopontin-derived fragments may modulate human hair growth given that human HFs expres
