Tenodesis of the long head of biceps is a common shoulder surgical procedure. Tenodesis can be performed either arthroscopically or open and within the glenohumeral joint, within the bicipital groove, or below the pectoralis major tendon insertion. Arthroscopic tenodesis of the biceps tendon reduces the risk of infection.

Insights into Interlayer Dislocation Augmented Zinc-Ion Storage Kinetics in MoS Nanosheets for Rocking-Chair Zinc-Ion Batteries with Ultralong Cycle-Life.

Increasing attention to sustainability and cost-effectiveness in energy storage sector has catalyzed the rise of rechargeable Zinc-ion batteries (ZIBs). However, finding replacement for limited cycle-life Zn-anode is a major challenge. Molybdenum disulfide (MoS), an insertion-type 2D layered material, has shown promising characteristics as a ZIB anode.

Role of Mesoporosity in Hard Carbon Anodes for High-Energy and Stable Potassium-Ion Storage.

Herein, NaCl-templated mesoporous hard carbons (NMCs) have been designed and engineered with tunable surface properties as anode materials for potassium-ion batteries (KIBs) and hybrid capacitors (KICs). By utilizing "water-in-oil" emulsions, the size of NaCl templates is precisely modified, leading to smaller particles that enable the formation of primary carbon structures with reduced particle size and secondary structures with 3D interconnected mesoporosity. These features significantly enhance electrode density, reduce particle-to-particle resistance, and improve electrolyte wettability.

Methods: A 16-month-old child weighing 10 kg accidentally ingested an unknown amount of Gramoxone containing paraquat. The child was transferred to a tertiary centre Paediatric Intensive Care Unit (PICU) where she was electively intubated and commenced on CRRT at 7 hours and 15 minutes post-ingestion.

Stroke phase differences in the linear relationship between swimming velocity and vertical body position during front crawl.

We aimed to investigate whether a linear relationship exists between swimming velocity and vertical body position for each stroke phase in front crawl, and to determine whether there are differences in the velocity effect among the stroke phases. Eleven male swimmers performed a 15 m front crawl at various swimming velocities. The whole-body centre of mass (CoM) was estimated from individual digital human models using inverse kinematics.

Exploring the role of splicing in TP53 variant pathogenicity through predictions and minigene assays.

Background: TP53 variant classification benefits from the availability of large-scale functional data for missense variants generated using cDNA-based assays. However, absence of comprehensive splicing assay data for TP53 confounds the classification of the subset of predicted missense and synonymous variants that are also predicted to alter splicing. Our study aimed to generate and apply splicing assay data for a prioritised group of 59 TP53 predicted missense or synonymous variants that are also predicted to affect splicing by either SpliceAI or MaxEntScan.

A decade of advances in human gut microbiome-derived biotherapeutics.

Microbiome science has evolved rapidly in the past decade, with high-profile publications suggesting that the gut microbiome is a causal determinant of human health. This has led to the emergence of microbiome-focused biotechnology companies and pharmaceutical company investment in the research and development of gut-derived therapeutics. Despite the early promise of this field, the first generation of microbiome-derived therapeutics (faecal microbiota products) have only recently been approved for clinical use.

One-quarter of freshwater fauna threatened with extinction.

Freshwater ecosystems are highly biodiverse and important for livelihoods and economic development, but are under substantial stress. To date, comprehensive global assessments of extinction risk have not included any speciose groups primarily living in freshwaters. Consequently, data from predominantly terrestrial tetrapods are used to guide environmental policy and conservation prioritization, whereas recent proposals for target setting in freshwaters use abiotic factors.

Heritable polygenic editing: the next frontier in genomic medicine?

Polygenic genome editing in human embryos and germ cells is predicted to become feasible in the next three decades. Several recent books and academic papers have outlined the ethical concerns raised by germline genome editing and the opportunities that it may present. To date, no attempts have been made to predict the consequences of altering specific variants associated with polygenic diseases.

Biomass carbon emissions from nickel mining have significant implications for climate action.

Global nickel demand is projected to double by 2050 to support low-carbon technologies and renewable energy production. However, biomass carbon emissions from clearing vegetation for nickel mining are rarely included in corporate sustainability reports or considered in mineral sourcing decisions. Here, we compiled data for 481 nickel mines and undeveloped deposits to show that the footprint of nickel mining could be 4 to 500 times greater than previously reported (depending on the mine site), and thus the environmental impacts of nickel products, including batteries, have been underestimated to date.

Aurora B inhibition induces hyper-polyploidy and loss of long-term proliferative potential in RB and p53 defective cells.

Polyploidy is a common outcome of chemotherapies, but there is conflicting evidence as to whether polyploidy is an adverse, benign or even favourable outcome. We show Aurora B kinase inhibitors efficiently promote polyploidy in many cell types, resulting in the cell cycle exit in RB and p53 functional cells, but hyper-polyploidy in cells with loss of RB and p53 function. These hyper-polyploid cells (>8n DNA content) are viable but have lost long-term proliferative potential in vitro and fail to form tumours in vivo.

Unlocking Therapeutic Potential: Mesenchymal Stem Cells-derived Exosomes in IUA Treatment, Current Status and Perspectives.

Intrauterine adhesion (IUA) is a condition caused by damage to the basal uterine layer which can lead to partial or full occlusion of the uterine cavity. Although traditional treatment options have been useful in mild and moderate cases, they have been unsatisfactory in severe IUA cases. Therefore, it is essential to improve the treatment strategies of IUA.
