Immunomodulatory, Antibacterial, Antioxidative and EGF‐Delivering Hydrogel Remodels Wound Microenvironment for Infected Diabetic Wound Healing

National Materials, EarlyView.
In this study, we engineered an antibacterial, antioxidative and epidermal grow factor‐encapsulated multifunctional hydrogel for the repair of chronic and refractory wounds. The hydrogel markedly promoted wound healing in rat models of diabetic foot ulcers and infected wounds by modulating wound microenvironment.

Numerical study on the effect of rim seal slot filleting on turbine endwall cooling

AIP Advances
In this study, the effect of rim seal slot filleting on turbine endwall film cooling performance is numerically investigated. For comparison with the baseline case, five different fillet radius and width (R/W) ratios are adopted, i.e., R/W = 1.25, 2.5, 3.

Seedling resistance and chemical defenses against Psylliodes chrysocephala: the roles of seed age and sinapinic acid in Sinapis alba and Brassica napus

Pest Management Science, EarlyView.
The cabbage stem flea beetle (Psylliodes chrysocephala) is a major pest of winter oilseed rape (Brassica napus). We tested B. napus and Sinapis alba seedlings for feeding resistance and underlying chemical defenses. S. alba was least damaged, while metabolite profiles revealed resistance‐linked compounds, highlighting breeding potential for insect ...

Artificial supplementary food influences hedgehog occupancy and activity patterns more than predator presence or natural food availability

Wildlife Biology, EarlyView.
Supplementary feeding for declining hedgehog Erinaceus europaeus populations is popular in Great Britain and has been suggested as an important factor in explaining higher densities in urban areas compared with rural ones. Occupancy modelling was used to test whether spatial variation in supplementary feeding, natural food, habitat, or predator ...

Effect of Outer Fin Axial Gap on the Sealing Effectiveness and Fluid Dynamics of Radial Rim Seal

, 2017
The modern gas turbine is widely applied in the aviation propulsion and power generation. The rim seal is usually designed at the periphery of the wheel-space and prevented the hot gas ingestion in modern gas turbines.

Facing Truths About Population Management

Zoo Biology, EarlyView.
Populations of wildlife, and domestic animals have large sinks for surplus animals. By contrast, zoos don't. Humans in industrialized societies are socialized with companion animals, i.e. surplus (i.e., typically denied reproduction) originating from unseen breeding cores.

A low‐cost, portable polarizing digital light microscope for monitoring crystal growth and for crystal harvesting

Journal of Applied Crystallography, EarlyView.
A low‐cost, portable, medium‐resolution polarizing digital light microscope device for monitoring crystal growth and for crystal harvesting is described. The device can be used with a cell phone or a personal computer for real‐time imaging by professional and amateur scientists alike.Motivated by the need for a convenient way to demonstrate the growth ...

Graft Height and Labral Integrity as Key Determinants of Suction Seal Restoration in Hip Labral Augmentation: Findings From an Ovine Model

Orthopaedic Journal of Sports Medicine
Background: The acetabular labrum plays a critical role in maintaining the hip suction seal, joint stability, and load distribution. When primary repair is not feasible, augmentation is preferred if the chondrolabral junction can be preserved, whereas ...
