Oxford hip and knee scores deteriorate in patients awaiting lower limb arthroplasty during the COVID-19 pandemic and predict a health state 'worse than death'.

The COVID-19 pandemic has caused unprecedented disruption to elective orthopaedic services. The primary objective of this study was to examine changes in functional scores in patients awaiting total hip arthroplasty (THA), total knee arthroplasty (TKA), and unicompartmental knee arthroplasty (UKA). Secondary objectives were to investigate differences between these groups and identify those in a health state 'worse than death' (WTD).

The genome sequence of the northern goshawk, (Linnaeus, 1758).

We present a genome assembly from an individual female (the northern goshawk; Chordata; Aves; Accipitriformes; Accipitridae). The genome sequence is 1,398 megabases in span. The majority of the assembly (99.

The Exocytosis Associated SNAP25-Type Protein, SlSNAP33, Increases Salt Stress Tolerance by Modulating Endocytosis in Tomato.

In plants, vesicular trafficking is crucial for the response and survival to environmental challenges. The active trafficking of vesicles is essential to maintain cell homeostasis during salt stress. Soluble N-ethylmaleimide-sensitive factor attachment protein receptors (SNAREs) are regulatory proteins of vesicular trafficking.

Involvement of SchRabGDI1 from Solanum chilense in endocytic trafficking and tolerance to salt stress.

Physiological responses of plants to salinity stress requires the coordinated activation of many genes. A salt-induced gene was isolated from roots of the wild tomato species Solanum chilense and named SchRabGDI1 because it encodes a protein with high identity to GDP dissociation inhibitors of plants. These proteins are regulators of the RabGTPase cycle that play key roles in intracellular vesicular trafficking.

Careful assessment the key to diagnosing adolescent heel pain.

The most common cause of adolescent heel pain is calcaneal apophysitis also known as Sever's disease. The condition may occur in adolescent athletes, particularly those involved in running or jumping activities, during the pubertal growth spurt. The mean age of presentation in Sever's disease is ten, (range 7-15).

Nanopit-induced osteoprogenitor cell differentiation: The effect of nanopit depth.

We aimed to assess osteogenesis in osteoprogenitor cells by nanopits and to assess optimal feature depth. Topographies of depth 80, 220 and 333 nm were embossed onto polycaprolactone discs. Bone marrow-derived mesenchymal stromal cells were seeded onto polycaprolactone discs, suspended in media and incubated.

Age and sex-selective predation moderate the overall impact of predators.

Currently, there is no general agreement about the extent to which predators impact prey population dynamics and it is often poorly predicted by predation rates and species abundances. This could, in part be caused by variation in the type of selective predation occurring. Notably, if predation is selective on categories of individuals that contribute little to future generations, it may moderate the impact of predation on prey population dynamics.

Cross-linking of neutrophil CD11b results in rapid cell surface expression of molecules required for antigen presentation and T-cell activation.

Recent studies suggest that neutrophils may play a role in antigen presentation. In support of this hypothesis it has been shown that these cells appear to contain cytoplasmic stores of molecules required for this function, i.e.
