Molecular basis of conjugation-mediated DNA transfer by gram-negative bacteria.

Curr Opin Struct Biol

January 2025

Institute of Structural and Molecular Biology, School of Natural Sciences, Birkbeck College, Malet Street, London, WC1E 7HX, United Kingdom; Institute of Structural and Molecular Biology, Division of Biosciences, University College London, Gower Street, WC1E 6BT, United Kingdom. Electronic address:

Bacterial conjugation is the unidirectional transfer of DNA (often plasmids, but also other mobile genetic elements, or even entire genomes), from a donor cell to a recipient cell. In Gram-negative bacteria, it requires the formation of three complexes in the donor cell: i-a large, double-membrane-embedded transport machinery called the Type IV Secretion System (T4SS), ii-a long extracellular tube, the conjugative pilus, and iii-a DNA-processing machinery termed the relaxosome. While knowledge has expanded regarding molecular events in the donor cell, very little is known about the machinery involved in DNA transfer into the recipient cell.

Factors Influencing Success in Endoscopic Treatment of Grade 4-5 Primary Vesicoureteric Reflux (VUR) in Infancy and Childhood.

J Pediatr Surg

January 2025

Chelsea & Westminster Hospital and Imperial College Hospitals (West London Children's Hospital Alliance), Imperial College London, United Kingdom. Electronic address:

Introduction: There is equipoise among pediatric urologists regarding endoscopic versus surgical intervention for symptomatic Grade 4-5 Vesicoureteric Reflux (VUR), particularly in infancy. Our aim was to assess outcomes of first-line endoscopic treatment in all cases of symptomatic Grade 4-5 VUR and we hypothesised that using endoscopic Dx/HA as first line management for primary VUR would obviate the need for ureteric reimplantation in the majority of cases.

Methods: Retrospective single-surgeon analysis of consecutive patients with primary Grade 4-5 VUR over 15 years.

The cortical tracking of the acoustic envelope is a phenomenon where the brain's electrical activity, as recorded by electroencephalography (EEG) signals, fluctuates in accordance with changes in stimulus intensity (the acoustic envelope of the stimulus). Understanding speech in a noisy background is a key challenge for people with hearing impairments. Speech stimuli are therefore more ecologically valid than clicks, tone pips, or speech tokens (e.

Introduction: Children growing up in arid and semi-arid regions of Sub-Saharan Africa (SSA) face heightened risks, often resulting in poor developmental outcomes. In Kenya, the arid and semi-arid lands (ASAL) exhibit the lowest health and developmental indicators among children. Despite these risks, some children grow up successfully and overcome the challenges.

Synthesis and Reactivity of Six-Membered Cyclic Diaryl λ3-Bromanes and λ3-Chloranes.

Angew Chem Int Ed Engl

January 2025

Cardiff University, School of Chemistry, Park Place, Main Building, CF10 3AT, Cardiff, UNITED KINGDOM OF GREAT BRITAIN AND NORTHERN IRELAND.

Despite the remarkable advancements in hypervalent iodine chemistry, exploration of bromine and chlorine analogues remains in its infancy due to their difficult synthesis. Herein, we introduce six-membered cyclic λ3-bromanes and λ3-chloranes. Through single-crystal X-ray structural analyses and conformational studies, we delineate the crucial bonding patterns pivotal for the thermodynamic stability of these compounds.

Insomnia and some insomnia treatments can impact an individual's daytime functioning. Here, we performed post hoc analyses of patient-reported outcomes from a phase 3 clinical trial to assess the impact of lemborexant (LEM), a dual orexin receptor antagonist, on daytime functioning. Adults with insomnia were randomized 1:1:1 to receive placebo, LEM 5 mg (LEM5) or LEM 10 mg (LEM10) for 6 months.

Background: Knowledge about the diet quality among youth who follow different types of plant-based diets is essential to understand whether support is required to ensure a well-planned diet that meets their nutritional needs. This study aimed to investigate how food groups, macronutrient intake, and objective blood measures varied between Norwegian youth following different plant-based diets compared to omnivorous diet.

Methods: Cross-sectional design, with healthy 16-to-24-year-olds (n = 165) recruited from the Agder area in Norway, following a vegan, lacto-ovo-vegetarian, pescatarian, flexitarian or omnivore diet.

Introduction: Evidence suggests that social prescribing might have a positive impact on identity, control, creativity and quality of life in people with dementia. While evidence on the benefits of social prescribing is accumulating, there is a sparsity of research on the experiences of social prescribers. This study aims to identify the challenges that social prescribers face when supporting people with dementia and their families and strategies to address these.

Dry evergreen Afromontane forests are severely threatened due to the expansion of agriculture and overgrazing by livestock. The objective of this study was to investigate the composition of woody species, structure, regeneration status and plant communities in Seqela forest, as well as the relationship between plant community types and environmental variables. Systematic sampling was used to collect vegetation and environmental data from 52 (20 m x 20 m) (400 m2) plots.

Smallholder farmers produce over 40% of global palm oil, the world's most traded and controversial vegetable oil. Awareness of the effects of palm oil production on ecosystems and human communities has increased drastically in recent years, with ever louder calls for the private and public sector to develop programs to support sustainable cultivation by smallholder farmers. To effectively influence smallholder practices and ensure positive social outcomes, such schemes must consider the variety in perspectives of farmers and align with their priorities.

Introduction: Haemodynamic atrioventricular delay (AVD) optimisation has primarily focussed on signals that are not easy to acquire from a pacing system itself, such as invasive left ventricular catheterisation or arterial blood pressure (ABP). In this study, standard clinical central venous pressure (CVP) signals are tested as a potential alternative.

Methods: Sixteen patients with a temporary pacemaker after cardiac surgery were studied.

We explore the efficacy of multimodal behavioral cues for explainable prediction of personality and interview-specific traits. We utilize elementary head-motion units named kinemes, atomic facial movements termed action units and speech features to estimate these human-centered traits. Empirical results confirm that kinemes and action units enable discovery of multiple trait-specific behaviors while also enabling explainability in support of the predictions.

Magnesium hydride (MgH) is a promising material for solid-state hydrogen storage due to its high gravimetric hydrogen capacity as well as the abundance and low cost of magnesium. The material's limiting factor is the high dehydrogenation temperature (over 300 °C) and sluggish (de)hydrogenation kinetics when no catalyst is present, making it impractical for onboard applications. Catalysts and physical restructuring (e.
