Update on tick-borne pathogens detection methods within ticks

Ticks are known vectors of various pathogens, including bacteria, parasites and viruses, that impact both animal and human health. Improving knowledge of the distribution of tick-borne pathogens, combined with their early detection in ticks, are essential steps to fight against tick-borne diseases and mitigate their impacts. Here we give an overview of what are the common methods of pathogen detec

RipD (Rv1566c) from mycobacterium tuberculosis : Adaptation of an NlpC/p60 domain to a non-catalytic peptidoglycan-binding function

Enzymes carrying NlpC/p60 domains, for instance RipA and RipB from Mycobacterium tuberculosis, are bacterial peptidoglycan hydrolases that cleave the peptide stems and contribute to cellwall remodelling during cell division.Amember of this protein family, RipD (Rv1566c) from M. tuberculosis described in the present study, displays sequence alterations in the NlpC/p60 catalytic triad and carries a

Is the shift in treatment patterns toward new, more expensive drugs still driving the increase in pharmaceutical expenditure? : A decomposition analysis of expenditure data in Sweden 1990-2022

BACKGROUND: Pharmaceutical expenditures (PE) are increasing worldwide raising concerns about sustainability. However, the current price index provides an incomplete picture of this trend due to the rapid introduction of new drugs on the market.OBJECTIVE: The aim of this study is to decompose PE into their components and investigate the development in Sweden from 1990 to 2022.METHODS: The PE index

Grain size control in quasi-two-dimensional perovskite thin film via intermediate phase engineering for efficient bound exciton generation

Quasi-two dimensional (2D) perovskites have emerged as a promising class of materials due to their remarkable photoluminescence efficiency, which stems from their exceptionally high exciton binding energies. The spatial confinement of excitons within smaller grain sizes could enhance the formation of biexcitons leading to higher radiative recombination efficiency. However, the synthesis of high-qu

Changes in waterbird occurrence and abundance at their northern range boundaries in response to climate warming : importance of site area and protection status

Climate warming is driving changes in species distribution, but habitat characteristics can interact with warming temperatures to affect populations in unexpected ways. We investigated wintering waterbird responses to climate warming depending on habitat characteristics, with a focus on the northern boundary of their non-breeding distributions where winter climatic conditions are more extreme. At

Evaluating the Applicability of a Real-Time Highly Oxygenated Organic Molecule (HOM)-Based Indicator for Ozone Formation Sensitivity at a Boreal Forest Station

Ground-level ozone (O3), formed via complex photochemistry involving nitrogen oxides (NOx) and volatile organic compounds (VOCs), is a critical secondary pollutant and oxidant. Therefore, understanding whether the formation of O3 is NOx- or VOC-limited is essential for effective air quality management. Recently, we demonstrated that the distribution of highly oxygenated organic molecules (HOMs) ca

Navigating Health Applications Realms : Consent Challenges and User Empowerment in European Law

This study delves into the landscape of health applications within online markets. These applications, offering health-related functionalities, have become integral to the lives of European citizens. The transformation of healthcare delivery, accelerated by the pace of modern life and accentuated by the COVID-19 pandemic, has elevated health applications from conveniences to essential tools capabl

Bacterial profile in human atherosclerotic plaques

Background and aimsSeveral studies have confirmed the presence of bacterial DNA in atherosclerotic plaques, but its contribution to plaque stability and vulnerability is unclear. In this study, we investigated whether the bacterial plaque-profile differed between patients that were asymptomatic or symptomatic and whether there were local differences in the microbial composition within the plaque.

Enhanced classification performance using deep learning based segmentation for pulmonary embolism detection in CT angiography

Purpose: To develop a deep learning-based algorithm that automatically and accurately classifies patients as either having pulmonary emboli or not in CT pulmonary angiography (CTPA) examinations. Materials and methods: For model development, 700 CTPA examinations from 652 patients performed at a single institution were used, of which 149 examinations contained 1497 PE traced by radiologists. The n

Quantitative flow ratio will supplant wire-based physiological indices : pros and cons

Quantitative flow ratio (QFR) represents a physiological index derived from angiography through three-dimensional (3D) quantitative coronary analysis. When compared to coronary angiography, QFR showed better performance both for guiding percutaneous coronary intervention (PCI) in case of intermediate coronary lesions and for optimising PCI results. In addition, QFR showed good diagnostic agreement

Grain alignment in hexaferrite permanent magnets by compaction at room and elevated temperatures

Shape-controlled precursors enable grain alignment without using an applied magnetic field in the permanent magnet material strontium hexaferrite. The effect is investigated by conducting four series of experiments using different compaction methods: two cold and two hot compactions. The hypothesis is that magnetic short-circuiting will diminish the grain alignment (texture) in cold compacted samp

Review article : Drought as a continuum – memory effects in interlinked hydrological, ecological, and social systems

Droughts are often long-lasting phenomena, without a distinct start or end and with impacts cascading across sectors and systems, creating long-term legacies. Nevertheless, our current perceptions and management of droughts and their impacts are often event-based, which can limit the effective assessment of drought risks and reduction of drought impacts. Here, we advocate for changing this perspec

Challenges in the practical implementation of blood biomarkers for Alzheimer's disease

Blood biomarkers have emerged as accessible, cost-effective, and highly promising tools for advancing the diagnostics of Alzheimer's disease. However, transitioning from cerebrospinal fluid biomarkers to blood biomarkers—eg, to verify amyloid β pathology—requires careful consideration. This Series paper highlights the main challenges in the implementation of blood biomarkers for Alzheimer's diseas

Touching through Music, Touching through Words : The performance and performativity of pianistic touch in musical and literary settings

This article investigates the versatile embodiment of touch in the sensory-aesthetic construction of piano performance. The sensorial interactions enmeshed in piano playing distribute a peculiar interaction between touch and sound, which can be comprehended as two kinds of pianistic touch–the physical touch and the affective touch. In the synthesis, or symbiosis, of these two kinds of touch, piano

International Ethnic Networks and Intra-Ethnic Conflict: Koreans in China

Since the normalization of Sino-Korean diplomatic relations in 1992, many South Koreans have moved to China for business, education, and other purposes. There they have encountered Korean-Chinese; ethnic Koreans who have lived in China for decades. This has lead to 'intra-ethnic conflict' which has divided Korean communities.
