COVIDomics
COVIDomics, namely, the proteomic and metabolomic signatures of COVID-19. Omics-based technologies have been largely adopted during the unprecedented global COVID-19 pandemic, allowing the scientific community to perform research on a large scale to understand the pathobiology of the SARS-CoV-2 infection and its replication into human cells. The application of omics techniques has been addressed to every level of application, from the detection of mutations, methods of diagnosis or monitoring, drug target discovery, and vaccine generation, to the basic definition of the pathophysiological processes and the biochemical mechanisms behind the infection and spread of SARS-CoV-2. Thus, the term COVIDomics wants to include those efforts provided by omics-scale investigations with application to the COVID-19 research.

Amino Acid Transporters and Stress Responses in Plants
Plants can absorb inorganic and organic nitrogen from the environment via the root system. In soil, inorganic nitrogen is usually found in the forms of nitrate and ammonium, while organic nitrogen usually exists in the forms of free amino acids, urea, and short peptides. The uptake of nitrogen-containing molecules by plants is mediated by the respective transporters of these molecules, especially amino acid transporters, which have been known to play a major role in distributing nitrogen throughout the whole plant. Amino acid accumulation and signaling have been suggested to play important roles in stress responses.

Fungal Origin and Safety
Fungi include yeasts, rusts, smuts, mildews, molds, mushrooms, and toadstools (harmful mushrooms). They are eukaryotes that comprise approximately 80,000 recognized species. Fungi are among the most widely distributed organisms on earth. As a natural gift, edible wild mushrooms growing in the wet and shadow places and picked by hand were used as a food. From searching mushrooms in the forests and producing single cell proteins (SCP) in small scales to mega production, academia, Organizations of United Nations, industries, political makers and others, play significant roles. Fermented traditional foods have also been reinvestigated, such as kefir, Miso, tempeh, and the like. They are an excellent source for fungal isolates for protein production. Fungal fermented foods and SCP are consumed either intentionally or unintentionally in our daily meals and have many applications in food and feed industries. Fungi are considered a potent alternative source of edible proteins and animal feed, mainly in the form of SCP, edible mushrooms, fungal fermented foods.

Vimentin-Binding Aptamer Motifs for Ovarian Cancer
The application of aptamers in biomedicine is emerging as an essential technology in the field of cancer research. As small single-stranded DNA or RNA ligands with high specificity and low immunogenicity for their targets, aptamers provide many advantages in cancer therapeutics over protein-based molecules, such as antibodies. Vimentin is an intermediate filament protein that is overexpressed in endothelial cells of cancerous tissue. High expression levels of vimentin have been associated with increased capacity for migration and invasion of the tumor cells. We have selected and identified thioated aptamers with high specificity for vimentin using human ovarian cancer tissues. Tentative binding motifs were chosen for two vimentin aptamers based on predicted secondary structures. Each of these shorter, tentative binding motifs was synthesized, purified, and characterized via cell binding assays. Two vimentin binding motifs with high fidelity binding were selected and further characterized via cell and tissue binding assays, as well as flow cytometric analysis. The equilibrium binding constants of these small thioated aptamer constructs were also determined. Future applications for the vimentin binding aptamer motifs include conjugation of the aptamers to synthetic dyes for use in targeted imaging and therapy, and ultimately more detailed and precise monitoring of treatment response and tumor progression in ovarian pathology.

Moonlighting Metalloproteinase
Protein moonlighting a.k.a. gene sharing has been defined as the concept that one protein processes multiple tasks and plays multiple roles [1]. Thus, multifunctional proteins are designated as moonlighting proteins. Matrix metalloproteinases play multiple roles in extracellular proteolysis and intracellular gene regulation [2,3], prompting us to propose a new definition of Moonlighting Metalloproteinase (MMP).

Lateral Flow Technologies Detect COVID-19
Lateral flow technology (also known as lateral flow assay) plays a critical role in POC testing, as the technique is rapid, cost-effective, and can be operated by untrained personnel. Lateral flow technologies can be classified as follows: lateral flow immunoassay (LFIA), nucleic acid lateral flow assay (NLFA), and nucleic acid lateral flow immunoassay (NALFIA). LFIA is able to detect antibodies/antigens, while NLFA uses a DNA or RNA probe to detect nucleic acid. Moreover, NALFIA uses both antibodies/antigens and nucleic acid as biomarkers for the detection of antigens/antibodies or amplicons.

Microglial Phagocytosis
       Multiple sclerosis (MS) is the most common autoimmune and demyelinating disease of the central nervous system (CNS), characterized, in the majority of cases, by initial relapses that later evolve into progressive neurodegeneration, severely impacting patients’ motor and cognitive functions. Despite the availability of immunomodulatory therapies effective to reduce relapse rate and slow disease progression, they all failed to restore CNS myelin that is necessary for MS full recovery. Microglia are the primary inflammatory cells present in MS lesions, therefore strongly contributing to demyelination and lesion extension. Thus, many microglial-based therapeutic strategies have been focused on the suppression of microglial pro-inflammatory phenotype and neurodegenerative state to reduce disease severity.

Binding of Various Aminopolycarboxylates
Synthetic aminopolycarboxylates like ethylenediaminetetraacetate (EDTA) are common chelating agents. EDTA-degrading bacterium Chelativorans sp. BNC1 uses an ABC-type transporter for the uptake of free EDTA into its cells for biodegradation. The key component of the transporter is a periplasmic EDTA-binding protein, EppA, and the structural and functional analyses indicate that EppA is a general binding protein for the uptake of free aminopolycarboxylates, suggesting that stable metal-chelate complexes are not transported into the cells for biodegradation and explaining the persistence of stable metal-EDTA complexes in the environment.

Redox Homeostasis in Poultry
Redox biology is a very quickly developing area of modern biological sciences, and roles of redox homeostasis in health and disease have recently received tremendous attention. There are a range of redox pairs in the cells/tissues responsible for redox homeostasis maintenance/regulation. In general, all redox elements are interconnected and regulated by various means, including antioxidant and vitagene networks. The redox status is responsible for maintenance of cell signaling and cell stress adaptation. Physiological roles of redox homeostasis maintenance in avian species, including poultry, have received limited attention and are poorly characterized. However, for the last 5 years, this topic attracted much attention, and a range of publications covered some related aspects. In fact, transcription factor Nrf2 was shown to be a master regulator of antioxidant defenses via activation of various vitagenes and other protective molecules to maintain redox homeostasis in cells/tissues. It was shown that Nrf2 is closely related to another transcription factor, namely, NF-κB, responsible for control of inflammation; however, its roles in poultry have not yet been characterized. Therefore, the aim of this study is to describe a current view on NF-κB functioning in poultry with a specific emphasis to its nutritional modulation under various stress conditions.
