Binding to thrive : Decoding Atopobium spp. interactions with host proteins and immune cells

Objectives: Gram-positive anaerobic cocci are opportunistic pathogens that exploit immune suppression or tissue injury to establish infections. Atopobium spp. are clinically relevant, being linked to bacterial vaginosis, abdominal wounds, pelvic abscesses, and dental infections. While clinical reports describe the involvement in detrimental host conditions, in-depth knowledge is missing to underst

Thorough clinical child psychiatric diagnostic evaluation and validation of the Autism- Tics, ADHD and other comorbidities inventory (A-TAC) in a population-based sample of 9-year-olds

Background: The Autism- Tics, ADHD and other Comorbidities inventory (A-TAC) has been validated in epidemiological data. However, validation against clinical diagnostic assessments in a population-based sample has been lacking, limiting the implications for clinical practice, clinical research and public health decisions. Methods: Study participants were recruited from the longitudinal Child and A

Effects of solution conditions on the self-assembly of the chaperone protein DNAJB6b

Chaperone proteins are essential for maintaining proteostasis. Their main role is to assist with the folding of other proteins and to prevent the aggregation of misfolded proteins. The molecular chaperone DNAJB6b efficiently suppresses amyloid formation of several peptides. This activity may rely on the same physicochemical properties as those driving chaperone self-assembly into large micellar-li

Mineralization of dental tissues and caries lesions detailed with Raman microspectroscopic imaging

Dental caries is the most common oral disease that causes demineralization of the enamel and later of the dentin. Depth-wise assessment of the demineralization process could be used to help in treatment planning. In this study, we aimed to provide baseline information for the development of a Raman probe by characterizing the mineral composition of the dental tissues from large composition maps (6

Subchondral bone plate thickness is associated with micromechanical and microstructural changes in the bovine patella osteochondral junction with different levels of cartilage degeneration

The influence of joint degeneration on the biomechanical properties of calcified cartilage and subchondral bone plate at the osteochondral junction is relatively unknown. Common experimental difficulties include accessibility to and visualization of the osteochondral junction, application of mechanical testing at the appropriate length scale, and availability of tissue that provides a consistent r

Characterisation of airway inflammation and proteomes associated with cystic fibrosis-related diabetes

Background: Cystic fibrosis (CF)-related diabetes (CFRD) is the most common extrapulmonary complication in CF. CFRD is associated with low lung function, but the underlying mechanisms are poorly understood. The aim of the present study was to compare airway inflammation and the airway proteome in people with CF (pwCF) with and without CFRD.Methods: Sputum samples from pwCF were analysed for neutro

Development of a leucine-rich repeat-containing protein 15-targeted radio-immunotheranostic approach to deplete pro-tumorigenic mechanisms and immunotherapy resistance

Leucine-rich repeat containing 15 (LRRC15) has emerged as an attractive biomarker and target for cancer therapy. Transforming growth factor-β (TGFβ) induces the expression of this plasma membrane protein specifically in aggressive and treatment resistant tumor cells derived from mesenchymal stem cells, with minimal expression observed in non-neoplastic tissues. We have developed a humanized monocl

Jet radius dependence of dijet momentum balance and suppression in Formula Presented collisions at 5.02 TeV with the ATLAS detector

This paper describes a measurement of the jet radius dependence of the dijet momentum balance between leading back-to-back jets in Formula Presented of Formula Presented collisions collected in 2018 and Formula Presented of Formula Presented collisions collected in 2017 by the ATLAS detector at the LHC. Both datasets were collected at Formula Presented TeV. Jets are reconstructed using the anti-Fo

Low nanomolar affinity to major grass pollen allergen Phl p 5 as achieved in an unmutated human antibody-lineage ancestor

BACKGROUND: Group 5 allergens, such as Phl p 5 of timothy grass, are major contributors to grass pollen allergy. Antibody 212597 specific for this allergen was recently isolated by single cell sequencing of bone marrow B cells of a grass pollen-allergic subject. This antibody, although subjected only to a low level of hypermutation resulting in six amino acid substitution across the heavy and ligh

Performance of quantitative PCR to distinguish Pneumocystis jirovecii pneumonia from colonisation in mmunocompromised patients

Background: Pneumocystis jirovecii pneumonia (PCP) is a severe opportunistic infection affecting immunocompromised patients. Quantitative polymerase chain reaction (qPCR) is widely used for the detection of P. jirovecii in respiratory samples. However, the diagnosis of PCP remains challenging and the high prevalence of P. jirovecii airway colonisation complicates the interpretation of positive res

Reversible tau hyperphosphorylation in hibernation : a blood biomarker and brain tissue study

Tau hyperphosphorylation, a key neuropathological feature of tauopathies such as Alzheimer’s disease (AD), also occurs physiologically during mammalian hibernation and is fully reversed upon arousal, offering a unique translational model to study tau metabolism. However, limited data exist on insoluble and soluble tau alterations during hibernation and on patterns of tau fragment concentrations in

Although organizational innovation capability plays a driver for the improvement of safety performance of High Reliability Organizations (HRO), knowledge management is a key link and important guarantee for them. However, there is no relevant research on how to achieve innovation of HRO through knowledge management. Previous research highlights that the dynamic and uncertain external environment o

Growth and oxidation of ultra-thin Pt-Sn layers on Pt(111) by molecular and atomic oxygen

The preparation of ultra-thin PtSn-alloyed layers by molecular beam epitaxy was studied using low-energy electron microscopy (LEEM) and micro-diffraction (μ-LEED). Deposition at a sample temperature of 435 °C initially results in the formation of a Pt3Sn/Pt(111) layer showing a (2 × 2) reconstruction. With continued Sn deposition, a Pt2Sn/Pt(111) layer develops, showing a (3×3)R30° reconstruction.

Measuring the effects of pitch accent realization and the patterning of head and eyebrow gestures on perceived multimodal prominence

Co-speech head and eyebrow gestures often align with pitch accents in spoken language production, thereby likely instantiating what we could refer to as multimodal prominence. Indeed, when speech is perceived audio-visually, controlled experimental studies have shown that both pitch accents and head and eyebrow gestures, when independently manipulated, have sizable effects on perceived prominence.

A Broad Survey and Functional Analysis of Immunoglobulin Loci Variation in Rhesus Macaques

Rhesus macaques (RMs) are a vital model for studying human disease and invaluable to pre-clinical vaccine research, particularly for the study of broadly neutralizing antibody responses. Such studies require robust genetic resources for antibody-encoding genes within the immunoglobulin (IG) loci. The complexity of the IG loci has historically made them challenging to characterize accurately. To ad

Directional capacity of a two detector array for localization of gamma emitting sources

Capacities for source localization in response to incidents involving radioactive materials are essential for effective, efficient response. In this context, the directional response of a detection system is of importance. Many solutions currently employed for source localization involve approaches that may be onerous with respect to cost, complexity and practicality for field operations. To avoid

The IFMIF-DONES facility provides a very high intensity flux of neutrons for research on materials of future fusion reactors and other complementary applications. The generation of those neutrons is driven by stripping reactions between energetic deuteron particles and a liquid lithium jet. The requirements on the deuteron beam are to deliver a 40 MeV beam with a constant current of 125 mA. All th

Land use modelling needs to better account for multiple cropping to inform pathways for sustainable agriculture

Multiple cropping, the simultaneous cultivation of several crops in space or time, is a global practice essential for intensifying and diversifying agriculture. Despite its substantial impact on environmental and socioeconomic outcomes of farming, multiple cropping is hardly accounted for in assessments of global food production, sustainability, and climate impacts. Such studies, often relying on
