Chromosome Conformation Signatures
Epigenetic mechanisms mediate the integration of genetic and environmental factors that are responsible for changes in phenotypes. The organisation of the human genome within three-dimensional space (the 3D genome) is a dynamic epigenetic regulator of phenotypic expression. Mediated through the changing spatial proximity of genomic regions relative to one another in 3D space, ‘chromosome conformations’ have emerged in the past several years as a novel class of molecular switches that regulate cellular and physiological processes. Technological advances in the detection of chromosome conformations have spawned a new class of biomarker - the chromosome conformation signature (CCS) - that identifies chromosomal interactions across multiple genomic loci as a collective marker of distinct epigenomic states. The use of CCSs in basic and clinical research has shown recent applications in identifying disease states, subtyping disease states, and prospectively stratifying individuals according to their likely response to medical intervention.

Ara (Genus)
Ara is a neotropical genus of macaws with eight extant species and at least two extinct species. The genus name was coined by French naturalist Bernard Germain de Lacépède in 1799. It gives its name to and is part of the Arini, or tribe of neotropical parrots. The genus name Ara is derived from the Tupi word ará, an onomatopoeia of the sound a macaw makes. The Ara macaws are large striking parrots with long tails, long narrow wings and vividly coloured plumage. They all have a characteristic bare face patch around the eyes. Males and females have similar plumage. Many of its members are popular in the pet trade, and bird smuggling is a threat to several species.

Small Spirocyclic, Xanthene-Based Fluorescent Probes
The use of fluorescent probes in a multitude of applications is still an expanding field. This review covers the recent progress made in small molecular, spirocyclic xanthene-based probes containing different heteroatoms (e.g., oxygen, silicon, carbon) in position 10′. After a short introduction, we will focus on applications like the interaction of probes with enzymes and targeted labeling of organelles and proteins, detection of small molecules, as well as their use in therapeutics or diagnostics and super-resolution microscopy. Furthermore, the last part will summarize recent advances in the synthesis and understanding of their structure–behavior relationship including novel computational approaches.

Rosemary
Rosemary (Rosemarinus officinalis L.) belongs to the Lamiaceae family and is native to the Mediterranean region and part of Asia. It is the most well-known plant with antioxidant activity, and the only one currently approved as natural antioxidant in EU (E-392). The main antioxidant components and the extraction procedures are reviewed in the present work.

Primary Cilia
Primary cilia are microtube-based organelles that extend from the cell surface and function as biochemical and mechanical extracellular signal sensors. Primary cilia coordinate a series of signaling pathways during development. Cilia dysfunction leads to a pleiotropic group of developmental disorders, termed ciliopathy. Phosphoinositides (PIs), a group of signaling phospholipids, play a crucial role in development and tissue homeostasis by regulating membrane trafficking, cytoskeleton reorganization, and organelle identity. Accumulating evidence implicates the involvement of PI species in ciliary defects and ciliopathies. The abundance and localization of PIs in the cell are tightly regulated by the opposing actions of kinases and phosphatases, some of which are recently discovered in the context of primary cilia.

AMP-activated Protein Kinase
We live and to do so we must breathe and eat, so are we a combination of what we eat and breathe? Here we will consider this question, and the role in this respect of the AMP-activated protein kinase (AMPK). Emerging evidence suggests that AMPK facilitates central and peripheral reflexes that coordinate breathing and oxygen supply, and contributes to central regulation of feeding and food choice. We propose, therefore, that oxygen supply to the body is aligned with not only the quantity we eat, but also nutrient-based diet selection, and that the cell-specific expression pattern of AMPK subunit isoforms is critical to appropriate system alignment in this respect. If this is the case, then aberrant cell-specific changes in the expression of AMPK subunit isoforms could give rise, in part, to known associations between a wide variety of conditions associated with metabolic disorder.

Almond, Hazelnut, Pistachio and their Skin
Nuts are dry, single-seeded fruits, with a combination of beneficial compounds that aid in disease prevention and treatment. Nuts’ skins are a good source of antioxidants thanks to the presence of polyphenolic compounds and other phytochemicals that can delay or inhibit lipid oxidation and neutralization of free radicals, contributing to disease prevention and treatments. Almond, hazelnut, pistachio are three very typical and common nuts.

Phenolic Compounds in Functional Pasta
Phenolic compounds are lost during the refining of flour and semolina, hence commonly consumed pasta is not a carrier of these components. Consumption of food products rich in phenolic compounds has been associated to reduced risk of chronic disease onset. Hence, several strategies have been developed to formulate functional pasta rich in phenolic compounds.  Whole grain, legume and composite flours are the main substituents of durum wheat semolina used for this purpose. Plant by-products from industrial food wastes have been also used as functional ingredients. In addition, pre-processing technologies on raw materials such as sprouting, or the modulation of extrusion/extrusion-cooking conditions, are valuable approaches to increase phenolic content in pasta.

Brassinosteroids in Growth and Development of Plants
Brassinosteroids (BRs) are a group of polyhydroxylated steroidal phytohormones that are required for the development, growth, and productivity of plants. These hormones are involved in regulating the division, elongation, and differentiation of numerous cell types throughout the entire plant life cycle.

Pancreatic β-Cell Dysfunction
Under healthy conditions, pancreatic β-cells produce and secrete the insulin hormone in response to blood glucose levels. Under diabetic conditions, however, β-cells are compelled to continuously secrete larger amounts of insulin to reduce blood glucose levels, and thereby, the β-cell function is debilitated in the long run.
