Destruction of habitat is the major cause for loss of biodiversity. This volume presents the population ecology of Atlantic salmon and brown trout and how it is influenced by the environment in terms ...of growth, migration, spawning and recruitment.
Advances in the site-specific chemical modification of proteins, also referred to as protein bioconjugation, have proved instrumental in revolutionary approaches to designing new protein-based ...therapeutics. Of the sites available for protein modification, cysteine residues or the termini of proteins have proved especially popular owing to their favorable properties for site-specific modification. Strategies that, therefore, specifically target cysteine at the termini offer a combination of these favorable properties of cysteine and termini bioconjugation. In this review, we discuss these strategies with a particular focus on those reported recently and provide our opinion on the future direction of the field.

Taking advantage of the coupling effect of contact electrification and electrostatic induction, triboelectric nanogenerators can effectively convert various forms of ambient mechanical energy into ...electricity, and therefore have attracted much attention, with broad applications in energy harvesting, active sensing, and biomedical therapy, which are anticipated to be an indispensable component in the era of the Internet of things. To improve the mechanical-to-electrical conversion, various strategies have been reported to engineer the materials used at the nanoscale with physical, chemical, biological, and hybrid approaches. These strategies to enhance the output performance and extend the applications of triboelectric nanogenerators are comprehensively reviewed and summarized in this article.

Triboelectric nanogenerators (TENGs) may provide a sustainable and pervasive energy solution in the era of “the Internet of Things.” Nanoengineering approaches to enhance the mechanical-to-electrical conversion and extend the applications of TENGs, including physical, chemical, biological, and hybrid strategies, are comprehensively reviewed by Zhou et al. Future research directions and opportunities are also discussed.
The market trend towards plant‐based protein has seen a significant increase in the last decade. This trend has been projected to continue in the coming years because of the strong factors of ...sustainability and less environmental impact associated with the production of plant‐based protein compared to animal, aside from other beneficial health claims and changes in consumers' dietary lifestyles. In order to meet market demand, there is a need to have plant‐based protein ingredients that rival or have improved quality and functionality compared to the traditional animal protein ingredients they may replace. In this review article, we present a detailed and concise summary of the functionality challenges of some plant protein ingredients with associated physical, chemical, and biological processing techniques (traditional and emerging technologies) that have been attempted to enhance them. We cataloged the differences between several studies that seek to address the functionality challenges of selected plant‐based protein ingredients without overtly commenting on a general technique that addresses the functionality of all plant‐based protein ingredients. Additionally, we elucidated the chemistry behind some of these processing techniques and how they modify the protein structure for improved functionality. Although, many food industries are shifting away from chemical modification of proteins because of the demand for clean label product and the challenge of toxicity associated with scale‐up of this technique, so physical and biological techniques are widely being adopted to produce a functional ingredient such as texturized vegetable proteins, hydrolyzed vegetable protein, clean label protein concentrates, de‐flavored protein isolates, protein flour, and grits.
Starch has been a convenient, economically important polymer with substantial applications in the food and processing industry. However, native starches present restricted applications, which hinder ...their industrial usage. Therefore, modification of starch is carried out to augment the positive characteristics and eliminate the limitations of the native starches. Modifications of starch can result in generating novel polymers with numerous functional and value-added properties that suit the needs of the industry. Here, we summarize the possible starch modifications in planta and outside the plant system (physical, chemical, and enzymatic) and their corresponding applications. In addition, this review will highlight the implications of each starch property adjustment.
A multifaceted coating for hard tissue implants, with favorable osteogenesis, angiogenesis, and osteoimmunomodulation abilities, would be of great value since it could improve osseointegration and ...alleviate prosthesis loosening. However, to date there are few coatings that fully satisfy these criteria. Herein we describe a microporous TiO2 coating decorated with hydroxyapatite (HA) nanoparticles that is generated by micro-arc oxidation of pure titanium (Ti) and followed annealing. By altering the annealing temperature, it is possible to simultaneously tune the coating's physical (morphology and wettability) and chemical (composites and crystallinity) properties. A coating produced with micro-arc oxidization (MAO) with an annealing temperature of 650 °C (MAO-650) exhibits numerous favorable physicochemical properties, such as hybrid micro-nano morphology, superhydrophilicity, and highly crystalline HA nanoparticles. In vitro experiments reveal that the MAO-650 coating not only supports proliferation and differentiation of both osteoblasts and endothelial cells, but also inhibits the inflammatory response of macrophages and enables a favorable osteoimmunomodulation to facilitate osteo/angio-genesis. In vivo evaluation mirrors these results, and shows that the MAO-650 coating results in ameliorative osseointegration when compared with the pristine MAO coating. These data highlight the profound effect of surface physicochemical properties on the regulation of osteo/angio-genesis and osteoimmunomodulation in the enhancement of osseointegration.

Numerous strategies for linking desired chemical probes with target peptides and proteins have been developed and applied in the field of biological chemistry. Approaches for site-specific ...modification of native amino acid residues in test tubes and biological contexts represent novel biological tools for understanding the role of peptides and proteins. Selective N-terminal modification strategies have been broadly studied especially in the last 10 years, as N-terminal positions are typically solvent exposed and provide chemically distinct sites for many peptide and protein targets, making N terminus distinct from other functional groups. A growing number of chemical and enzymatic techniques have been developed to modify N-terminal amino acids, and those techniques have the potential in the fields of medicine, basic research and applied materials science. This review focuses on appraising modification methodologies with the potential for biological applications from the past 10 years.
