#1
REVIEW
Conor F McGee
Agaricus bisporus is the most widely cultivated mushroom species in the world. Cultivation is commenced by inoculating beds of semi-pasteurised composted organic substrate with a pure spawn of A. bisporus. The A. bisporus mycelium subsequently colonises the composted substrate by degrading the organic material to release nutrients. A layer of peat, often called "casing soil", is laid upon the surface of the composted substrate to induce the development of the mushroom crop and maintain compost environmental conditions...

REVIEW
Tadayuki Ogawa, Nobutaka Hirokawa
The need for accurate description of protein behavior in solution has gained importance in various fields, including biophysics, biochemistry, structural biology, drug discovery, and antibody drugs. To achieve the desired accuracy, multiple precise analyses should be performed on the target molecule, compared, and effectively combined. This review focuses on the combination of multiple analyses in solution: size-exclusion chromatography (SEC), multi-angle light scattering (MALS), small-angle X-ray scattering (SAXS), analytical ultracentrifugation (AUC), and their complementary methods, such as atomic force microscopy (AFM) and mass spectrometry (MS)...

The incidence rates of phaeochromocytoma and colorectal cancer (CRC) are approximately 1 and 65 per 100,000 per year, respectively. Simultaneous presentation of these conditions is rare and poses unique management challenges. We report on treatment strategies and clinical outcomes in a series of patients with colorectal neoplasia and phaeochromocytoma. Demographic and clinical details of four patients over a 4-year period were reviewed. The median (range) age at first presentation was 66 (52-70) years. Phaeochromocytoma (2...

Tahereh Nosratzehi
Squamous cell carcinoma of oral cavity is of malignant tumors, which causes cancerous complications. DNA damage, mainly because of products of oxidative stress like reactive oxygen species, is a frequent mutagenic that triggers carcinoma. Smoking increases the probability of cancer incidence. Saliva is the first biological medium to interact with external compounds, especially smoking substances. The present study overviews the salivary level of some remarkable compounds in relation with smoking and squamous cell carcinoma...

REVIEW
Chenhua Zhang, Elliott Rodriguez, Cong Bi, Xiwei Zheng, Doddavenkatana Suresh, Kyungah Suh, Zhao Li, Fawzi Elsebaei, David S Hage
The last few decades have witnessed the development of many high-performance separation methods that use biologically related binding agents. The combination of HPLC with these binding agents results in a technique known as high performance affinity chromatography (HPAC). This review will discuss the general principles of HPAC and related techniques, with an emphasis on their use for the analysis of biological compounds and pharmaceutical agents. Various types of binding agents for these methods will be considered, including antibodies, immunoglobulin-binding proteins, aptamers, enzymes, lectins, transport proteins, lipids, and carbohydrates...

BACKGROUND: In 2012 a new cancer patient pathway for patients with non-specific symptoms and signs of cancer (NSSC-CPP) was introduced in Denmark. Limited information is available about the patients referred to the NSSC-CPP and the investigational course. The aim was to describe the population and the investigational course, estimate the prevalence of cancer and one-year mortality, and identify factors associated with a subsequent cancer diagnosis in patients referred to the NSSC-CPP...

Masato Kato, Steven L McKnight
In this review, we describe speculative ideas and early stage research concerning the flow of genetic information from the nuclear residence of genes to the disparate, cytoplasmic sites of protein synthesis. We propose that this process of information transfer is meticulously guided by transient structures formed from protein segments of low sequence complexity/intrinsic disorder. These low complexity domains are ubiquitously associated with regulatory proteins that control gene expression and RNA biogenesis, but they are also found in the central channel of nuclear pores, the nexus points of intermediate filament assembly, and the locations of action of other well-studied cellular proteins and pathways...

Boram Min, Kwang Chul Chung
Formation of toxic protein aggregates is a common feature and mainly contributes to the pathogenesis of neurodegenerative diseases (NDDs), which include amyotrophic lateral sclerosis (ALS), Alzheimer's, Parkinson's, Huntington's, and prion diseases. The transglutaminase 2 (TG2) gene encodes a multifunctional enzyme, displaying four types of activity, such as transamidation, GTPase, protein disulfide isomerase, and protein kinase activities. Many studies demonstrated that the calcium-dependent transamidation activity of TG2 affected the formation of insoluble and toxic amyloid aggregates that mainly consisted of NDD-related proteins...

Supurna Dhar, Hansi Kumari, Deepak Balasubramanian, Kalai Mathee
The bacterial cell-wall that forms a protective layer over the inner membrane is called the murein sacculus - a tightly cross-linked peptidoglycan mesh unique to bacteria. Cell-wall synthesis and recycling are critical cellular processes essential for cell growth, elongation and division. Both de novo synthesis and recycling involve an array of enzymes across all cellular compartments, namely the outer membrane, periplasm, inner membrane and cytoplasm. Due to the exclusivity of peptidoglycan in the bacterial cell-wall, these players are the target of choice for many antibacterial agents...

Barbara-Anne Battelle
The American horseshoe crab Limulus polyphemus (Linnaeus, 1758) is one of four extant species of xiphosuran chelicerates, the sister group to arachnids. Because of their position in the arthropod family tree and because they exhibit many plesiomorphic characteristics, Xiphosura are considered a proxy for the euchelicerate ancestor and therefore important for understanding the evolution and diversification of chelicerates and arthropods. Limulus polyphemus is the most extensively studied xiphosuran, and its visual system has long been a focus of studies critical for our understanding of basic mechanisms of vision and the evolution of visual systems in arthropods...

Cytochrome c oxidase (COX), the terminal enzyme of the electron transport system, is central to aerobic metabolism of animals. Many aspects of its structure and function are highly conserved, yet, paradoxically, it is also an important model for studying the evolution of the metabolic phenotype. In this review, part of a special issue honouring Peter Hochachka, we consider the biology of COX from the perspective of comparative and evolutionary biochemistry. The approach is to consider what is known about the enzyme in the context of conventional biochemistry, but focus on how evolutionary researchers have used this background to explore the role of the enzyme in biochemical adaptation of animals...

Plant oxylipins form a constantly growing group of signaling molecules that comprise oxygenated fatty acids and metabolites derived therefrom. In the last decade, the understanding of biosynthesis, metabolism, and action of oxylipins, especially jasmonates, has dramatically improved. Additional mechanistic insights into the action of enzymes and insights into signaling pathways have been deepened for jasmonates. For other oxylipins, such as the hydroxy fatty acids, individual signaling properties and cross talk between different oxylipins or even with additional phytohormones have recently been described...

The PIWI-interacting RNA (piRNA) pathway, one of the major eukaryotic small RNA silencing pathways, is a genome surveillance system that silences selfish genes in animal gonads. piRNAs guide PIWI protein to target genes through Watson-Crick RNA-RNA base-parings. Loss of piRNA function causes genome instability, inducing failure in gametogenesis and infertility. Studies using fruit flies and mice as key experimental models have resulted in tremendous progress in understanding the mechanism underlying the piRNA pathway...

Jean-François Lutz
Over the last ten years, the development of synthetic polymers containing controlled monomer sequences has become a prominent topic in fundamental and applied polymer science. This emerging area is particularly broad and combines classical polymer chemistry tools with techniques imported from other domains such as biology, biochemistry, organic synthesis, engineering, and bioanalytics. Consequently, it also generates new structures, terminologies, and applications that are not within the traditional scope of polymer science...

Cuticle is the most important structure that protects mosquitoes and other insect species from adverse environmental conditions and infections of microorganism. The physiology and biochemistry of insect cuticle formation have been studied for many years and our understanding of cuticle formation and hardening has increased considerably. This is especially true for flexible cuticle. The recent discovery of a novel enzyme that catalyzes the production of 3,4-dihydroxyphenylacetaldehyde (DOPAL) in insects provides intriguing insights concerning the flexible cuticle formation in insects...

REVIEW
Silvina Bartesaghi, Rafael Radi
In this review we provide an analysis of the biochemistry of peroxynitrite and tyrosine nitration. Peroxynitrite is the product of the diffusion-controlled reaction between superoxide (O2(•)(-)) and nitric oxide ((•)NO). This process is in competition with the enzymatic dismutation of O2(•-) and the diffusion of (•)NO across cells and tissues and its reaction with molecular targets (e.g. guanylate cyclase). Understanding the kinetics and compartmentalization of the O2(•-) / (•)NO interplay is critical to rationalize the shift of (•)NO from a physiological mediator to a cytotoxic intermediate...

This Review highlights how we can build upon the relatively new and rapidly developing field of research into bacterial quorum sensing (QS). We now have a depth of knowledge about how bacteria use QS signals to communicate with each other and to coordinate their activities. In recent years there have been extraordinary advances in our understanding of the genetics, genomics, biochemistry, and signal diversity of QS. We are beginning to understand the connections between QS and bacterial sociality. This foundation places us at the beginning of a new era in which researchers will be able to work towards new medicines to treat devastating infectious diseases, and use bacteria to understand the biology of sociality...
