Cold Plasma Systems for Medicine
Plasma is the predominant state of matter in the known universe (it is estimated that up to 99% of matter is plasma), although not on our planet, where the conditions of pressure and temperature make normal the states of matter—solid, liquid, and gas—that in global terms are exotic.  If we add energy to a gas, we will partially or totally ionize it. In this way, we reach a new state of matter, plasma, made up of free electrons, atoms and molecules (electrically neutral particles), and ions. The energy needed to generate plasma can be supplied through electrical discharges in gases, in which free electrons take energy field and lose it through excitation and ionization processes of the atoms and molecules in the gas. The interaction of a plasma with a surface, either solid, liquid or belonging to a live system, is a complex process involving many different active species and reactions. The use of cold plasma for medical applications is at present in the rise as it has been proven as a powerful therapeutic tool for healing, desinfection  and surface functionalization

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.

CCL2
Factors secreted from adipose tissue may induce and/or maintain a local and systemic low-grade activation of the innate immune system. Attraction of macrophages into adipose tissue and altered crosstalk between macrophages, adipocytes, and other cells of adipose tissue are symptoms of metabolic inflammation. Among several secreted factors attracting immune cells to adipose tissue, chemotactic C-C motif chemokine ligand 2 (CCL2) (also described as monocyte chemoattractant protein-1 (MCP-1)) has been shown to play a crucial role in adipose tissue macrophage infiltration.

WNT Signalling in Dental Pathologies
Great efforts have been made over the past decades to discover new therapeutic targets for a big variety of human pathologies. Most of the studies dealing with severe pathological conditions such as cancers and tissue malformations are focused on the role of either widely recognized master controlling genes such as ras and myc or pivotal components of key signalling pathways, among which Wnt and Notch. However, these genes and molecules are fundamental for paired embryogenesis as well as for tissue and organ homeostasis and regeneration, where they regulate cell proliferation, migration, differentiation and apoptosis. The precise timing and localization of their activation are important to ensure the appropriate cellular functions in physiological conditions. Thus, their indiscriminate targeting is not desirable, due to both the high risk of severe side effects and the certainty of broad phenotypic consequences. On the contrary, optimal therapeutic targets should be selected based on their tissue, time and pathology specific roles. Here, we suggest a paradigmatic example of such target molecules that could be represented by the Wnt/b-catenin signalling components Bcl9 and Bcl9l.

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.

Interferon Gamma
Interferon gamma (IFN-γ) is a dimerized soluble cytokine that is the only member of the type II class of interferons. The existence of this interferon, which early in its history was known as immune interferon, was described by E. F. Wheelock as a product of human leukocytes stimulated with phytohemagglutinin, and by others as a product of antigen-stimulated lymphocytes. It was also shown to be produced in human lymphocytes. or tuberculin-sensitized mouse peritoneal lymphocytes challenged with Mantoux test (PPD); the resulting supernatants were shown to inhibit growth of vesicular stomatitis virus. Those reports also contained the basic observation underlying the now widely employed IFN-γ release assay used to test for tuberculosis. In humans, the IFN-γ protein is encoded by the IFNG gene.

Glycosylation of Cancer Extracellular Vesicles
Glycans are major constituents of extracellular vesicles (EVs). Alterations in the glycosylation pathway are a common feature of cancer cells, which gives rise to de novo or increased synthesis of particular glycans. Therefore, glycans and glycoproteins have been widely used in the clinic as both stratification and prognosis cancer biomarkers. Interestingly, several of the tumor-associated glycans have already been identified in cancer EVs, which constitutes valuable sources of cancer biomarkers. Furthermore, glycans have also shown to play a role in EV protein sorting, uptake and tropism. Altogether, the EV glycan signatures hold tremendous potential to be applied into the clinical setting for both biomarker discovery and as therapeutic delivery systems.

Effects of Enclosure Complexity on Zoo Animals
Habitat complexity is important for the maintenance of high levels of welfare for captive animals, especially at zoos. Generally, individuals who experience greater enclosure complexity express higher diversity of behaviours and show better physiological well-being. However, positive outcomes of providing habitat complexity should be species-specific, and not all species would benefit from it. Thus, it is important to provide and constantly evaluate the habitat complexity of zoo animals.

Coatings Empowering Antiviral/Viricidal Properties
In the surge of the current, alarming scenario of SARS-CoV-2 infections, there is a immediate necessity for developing highly-innovative antiviral agents to work against the viruses with a broad spectrum of antiviral activity. Here-in, science-based methods, mechanisms, and procedures are implemented in obtaining resultant antiviral coated substrates, used in the destruction of the strains of the different viruses are presented. we pay particular attention to recent examples from the materials science and engineering field that highlight how some classes of antiviral drug candidates, such as polymeric materials, metal ions/metal oxides and functional nanomaterials result in acting against the viral spread. Based on the available literature and data, we also disclose some of the strategies for development of a universal and reusable virus deactivation system against the emerging COVID-19.
