Tendons are specialized matrix-rich connective tissues that transmit forces from muscle to bone and are essential for movement. As tissues that frequently transfer large mechanical loads, tendons are commonly injured in patients of all ages. Following injury, mammalian tendons heal poorly through a slow process that forms disorganized fibrotic scar tissue with inferior biomechanical function. Current treatments are limited and patients can be left with a weaker tendon that is likely to rerupture and an increased chance of developing degenerative conditions. More effective, alternative treatments are needed. However, our current understanding of tendon biology remains limited. Here, we emphasize why expanding our knowledge of tendon development, healing, and regeneration is imperative for advancing tendon regenerative medicine. We provide a comprehensive review of the current mechanisms governing tendon development and healing and further highlight recent work in regenerative tendon models including the neonatal mouse and zebrafish. Importantly, we discuss how present and future discoveries can be applied to both augment current treatments and design novel strategies to treat tendon injuries.Mid-infrared (MIR) photodetection, covering diverse molecular vibrational regions and atmospheric transmission windows, is vital to civil and military purposes. Versatile use of MIR photodetectors is commonly dominated by HgCdTe alloys, InSb, and quantum superlattices, which are limited by strict operation demands, high-cost, and environmental toxicity. Despite the rapid advances of black phosphorus (BP)-based MIR photodetectors, these are subject to poor stability and large-area integration difficulty. Here, the van der Waals (vdW) epitaxial growth of a wafer-scale 2D platinum ditelluride (PtTe2 ) layer is reported via a simple tellurium-vapor transformation approach. The 2D PtTe2 layer possesses a unique mosaic-like crystal structure consisting of single-crystal domains with highly preferential [001] orientation along the normal direction, reducing the influence of interface defects and ensuring efficient out-of-plane carrier transportation. This characteristic, combined with the wide absorption of PtTe2 and well-designed vertical device architecture, makes the PtTe2 /Si Schottky junction photodetector capable of sensing ultra-broadband light of up to 10.6 µm with a high specific detectivity. Also, the photodetector exhibits an excellent room-temperature infrared-imaging capability. This approach provides a new design concept for high-performance, room-temperature MIR photodetection based on 2D layered materials.

Uptake of non-medical prescribing by pharmacists working in primary care has been slow. This is despite benefits such as quicker and more efficient access to medicines for patients, a reduction in doctor workload, and enhanced professional satisfaction. This systematic review explores the views, opinions, and attitudes of pharmacists and graduates towards non-medical prescribing.

Medline, ScienceDirect, Embase, and the University of Reading Summon Service were searched to identify qualitative and mixed methods papers that examined the views, opinions, and attitudes of pharmacists and graduates towards non-medical prescribing. Papers published between January 2003 and September 2017 were included. Studies were quality assessed using the CASP checklist and then analysed using thematic synthesis.

After 85 full-text articles were assessed, a final 14 studies were eligible for inclusion. The included studies assessed pharmacists who currently prescribe, and other pharmacists and graduates with familiarity ofiminishing. Consideration of these will assist and advance pharmacist prescribing in primary care, leading to positive outcomes for both patient care and the pharmacy profession.

This review has identified themes and subsequent barriers and facilitators to non-medical prescribing. Many of the barriers are more perceived than real and are diminishing. Consideration of these will assist and advance pharmacist prescribing in primary care, leading to positive outcomes for both patient care and the pharmacy profession.Evolutionary rate explanations for latitudinal diversity gradients predict faster speciation and diversification rates in richer, older and more stable tropical regions (climatic stability hypothesis). click here Numerous modern lineages have emerged in high latitudes, however, suggesting that climatic oscillations can drive population divergence, at least among extratropical species (glacial refugia hypothesis). This conflicting evidence suggests that geographical patterns of evolutionary rates are more complicated than previously thought. Here, we reconstructed the complex evolutionary dynamics of a comprehensive data set of modern mammals, both terrestrial and marine. We performed global and regional regression analyses to investigate how climatic instability could have indirectly influenced contemporary diversity gradients through its effects on evolutionary rates. In particular, we explored global and regional patterns of the relationships between species richness and assemblage-level evolutionary rates and between evolutionary rates and climatic instability. We found an inverse relationship between evolutionary rates and species richness, especially in the terrestrial domain. Additionally, climatic instability was strongly associated with the highest evolutionary rates at high terrestrial latitudes, supporting the glacial refugia hypothesis there. At low latitudes, evolutionary rates were unrelated to climatic stability. The inverse relationship between evolutionary rates and the modern latitudinal diversity gradient casts doubt on the idea that higher evolutionary rates in the tropics underlie the current diversity patterns of modern mammals. Alternatively, the longer time spans for diversity to accumulate in the older and more stable tropics (and not high diversification rates) may explain the latitudinal diversity gradient.The porous nano-sized metal-organic framework (nanoMOF) and its proper surface modification could greatly promote the drug loading capability and introduce biocompatibility, biodegradability, and targeting functions into nano-drug delivery systems. Herein, the HACD@ADA-PA/MIL-101_NH2 (Fe)-P nanoparticle was successfully fabricated through supramolecular and coordination interactions from three building blocks, including hierarchically porous MIL-101_NH2 (Fe)-P nanoMOF, phosphite-modified adamantane (ADA-PA), and β-cyclodextrin (β-CD)-modified hyaluronic acid (HACD). The obtained HACD@ADA-PA/MIL-101_NH2 (Fe)-P nanoparticle was nano-sized and highly stable in physiological fluids. The porous structure of HACD@ADA-PA/MIL-101_NH2 (Fe)-P nanoparticle could effectively load the commercial chemotherapeutic drug doxorubicin (DOX) with an encapsulation rate of 41.20 % and a loading rate of 48.84 %. The obtained drug-loaded HACD@ADA-PA/MIL-101_NH2 (Fe)-P@DOX nanoparticle was pH-sensitive and relatively stable at neutral condition (pH 7.
