Lamin-A/C expression in immune cells
Nuclear envelope lamin A/C type-V intermediate filaments are a major constituent of the mammalian nuclear lamina, a dense fibrous protein meshwork located in the nuclear interior. Lamin A/C proteins control nuclear mechanics and structure and modify cellular signaling, gene transcription, epigenetic regulation, cell cycle progression, cell differentiation, and cell migration. The immune system is constituted by the innate and adaptive immunity. Innate immune response is mediated by myeloid cells such as neutrophils, macrophages, and dendritic cells. These cells produce a rapid and nonspecific response through phagocytosis, cytokine production, and complement activation, as well as activating adaptive immunity. Specific adaptive immune response is provoked by antigen presentation by antigen presenting cells (APCs) and the cytokine milieu, and is mainly mediated by the cellular functions of T cells and the production of antibodies by B cells. Unlike most cell types, immune cells regulate their lamin A/C protein expression relatively rapidly to exert their functions, with expression increasing in macrophages, reducing in neutrophils, and increasing transiently in T cells. In this article, it is discussed and summarized studies that have addressed the regulation of the expression of lamin A/C in cells of the innate and adaptive immune system.

Antisense Oligonucleotide-Based Therapy of Viral Infections
Antisense oligonucleotide (ASO) technology exploits a single-strand short oligonucleotide to either cause target RNA degradation or sterically block the binding of cellular factors or machineries to the target RNA. Chemical modification or bioconjugation of ASOs can enhance both its pharmacokinetic and pharmacodynamic performance, and it enables customization for a specific clinical purpose. ASO-based therapies have been used for treatment of genetic disorders, cancer and viral infections. In particular, ASOs can be rapidly developed for newly emerging virus and their reemerging variants.

5-HT2A Receptor Ligands Against Depression
According to the World Health Organization, depression is a multifactorial disorder that affects around 350 million people worldwide. The most widespread monoamine of the CNS-serotonin (5-HT) is believed to play a vital role in the pathomechanism of this condition, and the importance of the neurotransmitter is elevated by the "serotonin hypothesis", linking the presence of the depression-like symptoms with diminished 5-HT concentration in certain brain regions. Serotonin acts its biological effects via numerous receptors. Out of all seven types of serotonin receptors, the serotonin 2A receptor has been identified as a most promising molecular target valuable for the treatment of mood disorders. Recent medicinal chemistry findings on the structure and function of the serotonin 2A (5-HT2A) receptor facilitated design and discovery of novel anti-depressants.

Blockchain Applications in Agribusiness
Blockchain is a communication network where data is stored and shared in a distributed manner among all its nodes and links, eliminating any reliable authority centralized in different business models and where each node can assume coordination without a unified data center. Blockchain is a chain of blocks of information forming a distributed database where a group of people controls, records, and shares information used in various types of applications and is interconnected through platforms and hardware worldwide.

The Applications of Microphysiological Systems in Biomedicine: Impact on Urologic and Orthopaedic Research
Microphysiological systems (MPSs) are in vitro models that can incorporate dynamic stimuli such as flow, pressure and contraction in cell culture, enabling the formation of cellular architectures and retrieving physiological function often absent in conventional 2D-cell culture. MPS applications saw a substantial growth in recent years, drawing attention from industry as a strategy to optimize pre-clinical drug-development purposes, as well as from biomedical research, to fill a gap between in vivo and in vitro models. Several MPS platforms are now available and are employed in the development of bone and kidney complex systems for urologic and orthopaedic research. These advances have enabled, for example, the in vitro modelling of bone regeneration and renal drug secretion, and have dramatic potential to improve research into both orthopaedic and urology cancers.

Mechanobiology of Chondrocytes
This entry is associated with a review article, published in MDPI Applied Sciences on 23 April 2020, about the current knowledge on the mechanical stimulation of mesenchymal stem cells for cartilage regeneration. Loading stresses, physiologically experienced by chondrocytes, regulate the production of glycosaminoglycan and collagen, as well as promote and preserve cell viability. Therefore, there is a rising interest in the development of devices that impose mechanical stimuli, such as compression and shear stress, on mesenchymal stem cells. The mentioned review will analyze the dynamics within the joint, the physiological stimuli experienced by the chondrocytes, and how the biomechanical stimulation can be applied to a stem cell culture in order to induce chondrogenesis. In addition to that, paper lists some of the current applications in the field.

Bifunctional Beta-Lactam Antibiotics
The molecular structure of β-lactam antibiotics can be modified either to introduce another β-lactam ring (the pharmacophore conferring bactericidal activities to these molecules), or to add other pharmacophores that modify their pharmacological properties and spectrum of action.

Biochar with Alternate-Wetting and Drying-Irrigation
  To minimize excess water usage, alternate wetting and drying (AWD) irrigation practice is considered as an efficient technique in which soil intermittently dried during the growing period of rice by maintaining yield compared to a flooded system. Continuous AWD may result in poor soil health caused by carbon loss, nutrient depletion, cracking, and affecting soil physical properties. Due to being a potential organic amendment, biochar has a great scope to overcome these problems by improving soil’s physicochemical properties.

Mass Spectrometry Imaging
Mass spectrometry imaging (MSI) or imaging mass spectrometry (IMS) is a promising analytical method to determine and visualize the spatial distribution of specific chemical compositions by their molecular weights or m/z values. MSI is basically a two-dimensional analysis method that can detect intact molecules within tissues or tissue sections without necessitating extraction, purification, and separation.
