TL;DR: This review will focus on the strategies that have been developed for formulating hydrogels with ideal properties for bone regeneration applications, and aspects related to the improvement of hydrogel’ mechanical competence, controlled delivery of drugs and growth factors are treated in detail.
Abstract: Over the past few decades, bone related disorders have constantly increased. Among all pathological conditions, osteoporosis is one of the most common and often leads to bone fractures. This is a massive burden and it affects an estimated 3 million people only in the UK. Furthermore, as the population ages, numbers are due to increase. In this context, novel biomaterials for bone fracture regeneration are constantly under development. Typically, these materials aim at favoring optimal bone integration in the scaffold, up to complete bone regeneration; this approach to regenerative medicine is also known as tissue engineering (TE). Hydrogels are among the most promising biomaterials in TE applications: they are very flexible materials that allow a number of different properties to be targeted for different applications, through appropriate chemical modifications. The present review will focus on the strategies that have been developed for formulating hydrogels with ideal properties for bone regeneration applications. In particular, aspects related to the improvement of hydrogels’ mechanical competence, controlled delivery of drugs and growth factors are treated in detail. It is hoped that this review can provide an exhaustive compendium of the main aspects in hydrogel related research and, therefore, stimulate future biomaterial development and applications.

TL;DR: In this paper, the authors construct static and dynamic plane symmetric wormholes by surgically grafting together two spacetimes of plane-symmetric vacuum solutions with a negative cosmological constant.
Abstract: Using the cut-and-paste procedure, we construct static and dynamic, plane symmetric wormholes by surgically grafting together two spacetimes of plane symmetric vacuum solutions with a negative cosmological constant. These plane symmetric wormholes can be interpreted as domain walls connecting different universes, having planar topology, and upon compactification of one or two coordinates, cylindrical topology or toroidal topology, respectively. A stability analysis is carried out for the dynamic case by taking into account specific equations of state, and a linearized stability analysis around static solutions is also explored. It is found that thin-shell wormholes made of a dark energy fluid or of a cosmological constant fluid are stable, while thin-shell wormholes made of phantom energy are unstable.

TL;DR: In this article, the role of fatigue and oxidation in crack growth has been investigated at 650°C under typical loading waveforms at selected loading frequencies, and the results show that mixed time and cycle dependent crack growth seems to be the predominant crack growth mode in the two PM nickel alloys studied.

TL;DR: In this article, the authors compared trends, mechanisms and consequences of both AA and TA over the two Poles and found that AA over the AP is warming at a rate almost four times than the global means and twice as fast over the TP.
