Francis Perrin
Francis Perrin (17 August 1901 – 4 July 1992) was a France physicist,[1] the son of Nobel prize-winning physicist Jean Perrin. Francis Perrin was born in Paris and attended École Normale Supérieure in Paris. In 1928 he obtained a doctorate in mathematical sciences from the faculté des sciences of Paris, based upon a thesis on Brownian motion[2] and became a faculty member of Collège de

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.

CRISPR Towards a Sustainable Agriculture
Climate change and the need to feed an increasing population undermines food production and safety, representing the reasons behind the development of a new agriculture that is much more sustainable, productive and accessible worldwide. Genome editing and, in particular, clustered regularly interspaced palindromic repeats/CRISPR-associated protein (CRISPR/Cas) tools will play a major role in plant breeding to address these concerns. CRISPR/Cas includes a series of genome editing tools relying on the recognition and cleavage of target DNA/RNA sequences to introduce specific mutations.

Rapid Nontranscriptional Effects of Calcifediol and Calcitriol
Classically, a secosteroid hormone, vitamin D, has been implicated in calcium and phosphate homeostasis and has been associated with the pathogenesis of rickets and osteomalacia in patients with severe nutritional vitamin D deficiency. The spectrum of known vitamin D-mediated effects has been expanded in recent years. However, the mechanisms of how exactly this hormone elicits its biological function are still not fully understood. The interaction of this metabolite with the vitamin D receptor (VDR) and, subsequently, with the vitamin D-responsive element in the region of specific target genes leading to the transcription of genes whose protein products are involved in the traditional function of calcitriol (known as genomic actions). Moreover, in addition to these transcription-dependent mechanisms, it has been recognized that the biologically active form of vitamin D3, as well as its immediate precursor metabolite, calcifediol, initiate rapid, non-genomic actions through the membrane receptors that are bound as described for other steroid hormones. So far, among the best candidates responsible for mediating rapid membrane response to vitamin D metabolites are membrane-associated VDR (VDRm) and protein disulfide isomerase family A member 3 (Pdia3).

Resveratrol Treatment and Periodontal Disease
Resveratrol is an anti-inflammatory compound found in several foods. Periodontal disease (PD) is associated to other systemic diseases, and inflammation may be responsible for the association.

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.

Applications of Plant Genome Sequencing
The genome sequence of any organism is key to understanding the biology and utility of that organism. Plants have diverse, complex and sometimes very large nuclear genomes, mitochondrial genomes and much smaller and more highly conserved chloroplast genomes. Plant genome sequences underpin our understanding of plant biology and serve as a key platform for the genetic selection and improvement of crop plants to achieve food security.

Oxysterol Sulfation
Oxysterols have long been believed to be ligands of nuclear receptors such as liver X receptor (LXR) and play an important role in lipid homeostasis and in the immune system, where they are involved in both transcriptional and posttranscriptional mechanisms. However, they are increasingly associated with a wide variety of other, sometimes surprising, cell functions. Oxysterols have also been implicated in several diseases such as metabolic syndrome. Oxysterols can be sulfated, and the sulfated oxysterols act in different directions: they decrease lipid biosynthesis, suppress inflammatory responses, and promote cell survival. Our recent reports have shown that oxysterol and oxysterol sulfates are paired epigenetic regulators, agonists, and antagonists of DNA methyltransferases, indicating that their function of global regulation is through epigenetic modification.

Monarda Species
The genus Monarda (family Lamiaceae) contains 22 species of which three are native to southern Alabama, M. citriodora, M. fistulosa, and M. punctata. Several species of Monarda have been used in traditional medicines of Native Americans, and this present study is part of an ongoing project to add to our understanding of Native American pharmacopeia.

Persea americana
Persea americana, commonly known as avocado, has recently gained substantial popularity and is often marketed as a “superfood” because of its unique nutritional composition, antioxidant content, and biochemical profile. However, the term “superfood” can be vague and misleading, as it is often associated with unrealistic health claims. This article provides a comprehensive summary and assessment of the studies performed in the literature to understand the nutritional and therapeutic properties of avocado and its bioactive compounds.
