Abstract

Tissue engineering emerged back in the 1990s as a new concept to overcome the problem of tissue and organ failure. Over recent decades, there has been incredible progress towards the regeneration of tissues such as bone, heart valves, cartilage, cornea, and retina. In terms of ocular tissue engineering, despite the scientific and strategic incentive for reconstructing ocular tissues, there is also a tremendous need for novel therapeutic options in treating numerous eye diseases related to tissue failure. The aim of this Special Issue is to discuss tissue engineering applications of ocular tissues including but not limited to cornea, retina, and lenses.

Abstract

Imaging methods such as X-ray microscopy are used in non-destructive material analysis to achieve resolutions in the sub micrometer range. Imaging optics are required, for which X-ray lenses are particularly suitable for photon energies above 10 keV. To ensure the universal use of these lenses with constant optical properties over a wide photon energy range, for the first time an X-ray zoom lens was developed in this work.

Abstract

Legume crops provide an excellent source of high quality plant protein and have a key role in arable crop rotations reducing the need for fertilizer application and acting as break-crops. However, these crops are affected by a number of foliar and root diseases, being ascochyta blights the most important group of diseases worldwide. Ascochyta blights are incited by different pathogens in the various legumes. A number of control strategies have been developed including resistance breeding, cultural practices and chemical control. However, only marginal successes have been achieved in most instances, most control methods being uneconomical, hard to achieve or resulting in incomplete protection. This eBook covers recent advances in co-operative research on these diseases, from agronomy to breeding, covering traditional and modern genomic methodologies.

Abstract

In many research areas X-rays are used for analysis. In X-ray full field microscopy a high resolution is achievable independent of the source properties by using imaging lenses. With an objective lens with 100 mm focal length a theoretical resolution of 60nm is achievable at 30 keV. In Experiments a resolution of 200 nm for a field of view of 80 µm

Abstract

In recent years, great attention has been paid to polyphenols due to their positive effects on health. One of the most widely-studied phenolic compounds is resveratrol. This molecule, which is naturally present in some foods, shows beneficial effects on various physiological and biochemical processes, thus representing a potential tool for the prevention or the treatment of diseases highly prevalent in our society. Several of these beneficial effects have been observed in human beings, but others only in pre-clinical studies so far, and therefore, it is mandatory to continue with the scientific research in this field. Indeed, new knowledge concerning these issues could enable the development of novel functional foods or nutraceuticals, incorporating resveratrol, suitable for preventing or treating diseases such as cancer, cardiovascular diseases, obesity, dislipemia, insulin resistance and diabetes, liver diseases, etc.

Abstract

Microtechnology has changed our world since the last century, when silicon microelectronics revolutionized sensor, control and communication areas, with applications extending from domotics to automotive, and from security to biomedicine. The present century, however, is also seeing an accelerating pace of innovation in glassy materials; as an example, glass-ceramics, which successfully combine the properties of an amorphous matrix with those of micro- or nano-crystals, offer a very high flexibility of design to chemists, physicists and engineers, who can conceive and implement advanced microdevices. In a very similar way, the synthesis of glassy polymers in a very wide range of chemical structures offers unprecedented potential of applications. The contemporary availability of microfabrication technologies, such as direct laser writing or 3D printing, which add to the most common processes (deposition, lithography and etching), facilitates the development of novel or advanced microdevices based on glassy materials. Biochemical and biomedical sensors, especially with the lab-on-a-chip target, are one of the most evident proofs of the success of this material platform. Other applications have also emerged in environment, food, and chemical industries. The present Special Issue of Micromachines aims at reviewing the current state-of-the-art and presenting perspectives of further development. Contributions related to the technologies, glassy materials, design and fabrication processes, characterization, and, eventually, applications are welcome.
