The outbreak of coronavirus disease 2019 (COVID-19) has resulted in a world-wide crisis. To contain the virus, it is important to find infected individuals and isolate them to stop transmission. Various diagnostic techniques are used to check for infection. With the havoc that severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has created, it is imperative to work on alternative diagnostic techniques that can be used at both point of care with little or no expertise and at mass testing (i.e., when screening). Despite extensive research, to this date no specific effective treatment or cure is available to neutralize this viral infection. Globally, researchers are working to develop effective treatments, and several vaccines have been approved for public use. We found the studies that we explored for this review using appropriate key words for indexing in PubMed and Google Scholar from 2019 to 2020. We compile various techniques that have been used worldwide to diagnose and treat SARS-CoV-2 and discuss novel methods that may be modified for use in diagnosis and treatment. It is crucial to develop a more specific serological test for diagnosis that can rule out the possibility of COVID-19 and be used for mass testing. An affordable, safe, targeted, effective treatment must be developed to cure this disease, which has created a public health emergency of international concern.It is hypothesized that bone cells can sense mechanical force in the extracellular network via an electrical signal. This has led to the use of electrical stimulation (ES) to improve fracture repair and mitigate bone loss. Although overlap exists in bone maintenance and fracture healing mechanics, the processes involved in both are very different, resulting in dissimilar behaviors from the cells. Osteocytes are the most abundant cell type in bone tissue, and their basic structure and lineage are fairly well understood, but much debate is present regarding their behavior, with even less known about their behavior in electrical environments. A wide range of research exists on cell behavior under different types of ES, but it is difficult to draw conclusions due to the large variance in stimulation parameters, cell types, and origins (locations and species). By exploring behavior of multiple bone-cell types under different forms of ES, as well as mechanical stimulation through fluid flow, we can determine more about cell reactions to stimuli. In turn, a better understanding of cell response has the potential to improve and broaden therapeutic applications of ES for bone healing and bone loss mitigation, and enhance outcomes for osseointegration into implantable medical devices. These require greater understanding of the bone cellular environment from an electrical perspective as well as cellular responses to ES.Among various epithelial-to-mesenchymal transition (EMT)-related transcription factors (TFs), altered expression levels of Snail-1, Snail-2/Slug, Twist, and ZEB1 have shown a significant association in different cancers having a higher risk of metastasis. However, their role in the circulation of endometriosis patients is not well understood. Hence, the present study was designed to evaluate the crucial role of these TFs in defining the molecular pathogenesis for endometriosis progression and differentiation from control subjects. The qualitative and quantitative expression analysis of Snail-1, Snail-2/Slug, Twist, and ZEB1 were analyzed in peripheral blood samples of 75 different stages of endometriosis patients and compared with 50 control subjects. Total RNA was extracted and converted into complementary DNA (cDNA) for relative quantification of each gene transcript using SYBRGreen-based reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). The Livak method of relative quantification was used for calculating the fold change in each TF compared with endogenous control. All four selected TFs showed significantly upregulated expression levels in endometriosis patients compared with control subjects. A three-fold increase was observed for Snail-1 (p = 0.0001), and a two-fold increase was observed for Snail-2 (p = 0.01), Twist (p = 0.0002), and ZEB1 (p = 0.001) in stage III and IV compared with stage I and II of endometriosis patients. The present study revealed that EMT-related TFs play a crucial role in the pathogenesis and differentiating different stages of endometriosis patients through expression analysis of specific molecular cascades using non-invasive tools.EphB4 is a membrane tyrosine kinase receptor involved in a number of physiologic and pathologic conditions, cancer being the one drawing the highest attention. In mammalians, EphB4 regulates blood vessel growth and differentiation. EphB4 also mediates a number of cancer promoting effects including angiogenesis, invasion, and metastasis. Its effects have been linked to both EphrinB2-dependent and to EphrinB2-independent mechanisms. In spite of its emerging role in physiology and disease, the regulation of EphB4 cellular expression has been poorly described until recently. The present mini-review summarizes the latest findings on EphB4 regulation at the transcriptional and post-transcriptional level and discusses the biologic implications of such novel findings. Perspective on the scenarios opened by such findings and the open questions in EphB4 research is also provided.Polycystic ovarian syndrome (PCOS) is a heterogeneous, persistent endocrine disease that is generally identified in 6-10% of women of reproductive age. Intriguingly, about 55-65% of patients with PCOS display insulin resistance (IR), which can be related to their body weight, ethnicity, or age. Discovering the root cause of PCOS is of particular concern due to IR and abnormal androgen secretion, and continuous attempts have been made to define the complex pathogenic network underlying the syndrome. In addition, PCOS reflects connections between various proteins, genes, and epigenetics affected by environmental influences. Genetic factors such as mutation, epigenetics, and/or expression in noncoding RNAs, particularly miRNA222, play an important role in PCOS pathophysiology and cannot be neglected. Metformin has been used traditionally as a pillar of PCOS treatment, but even effective insulin sensitization therapy can contribute to side effects that reduce patient adherence and limit treatment effectiveness. Therefore, many of the PCOS characteristics can be taken into account for the impact on hyperinsulinemic ovaries which is important in order to develop treatment strategies. Thus our primary objective is to research the therapeutic efficacy of vitamin D in the suppression of miR222 and, secondary to miR222, mediated molecular pathways involving insulin resistance and metabolic defects, which influence ovarian activity, anovula-tion, and finally infertility.The purpose of this study was to elucidate the role that the miR-18a-5p/THBD regulatory pathway plays in endometrial cancer (EC), which could provide a theoretical basis for potential therapeutic targets. Differentially expressed genes in EC tissue and normal tissue were determined by bioinformatics analysis. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) was used to compare the expression of miR-18a-5p and THBD mRNA in normal human endometrial cells and human EC cells. CCK-8 assay was used to compare the proliferative ability of EC cells in different treatment groups. Transwell assay was used to detect the migratory and invasive abilities of EC cells in different treatment groups. Dual-luciferase assay was used to verify the targeting relationship between miR-18a-5p and THBD. Western blot assay was used to detect THBD protein expression level. qRT-PCR results showed that miR-18a-5p was significantly upregulated in EC cells, and expression of its target gene, THBD, was significantly downregulated. CCK-8 and transwell assays showed that miR-18a-5p could enhance the proliferative, migratory, and invasive abilities of EC cells, whereas THBD could weaken those abilities. Dual-luciferase assay confirmed that miR-18a-5p could negatively regulate THBD expression. In addition, rescue experiments revealed that the oncogenic effect of miR-18a-5p on EC cells was inhibited by THBD overexpression. We conclude that miR-18a-5p could promote the proliferation, migration, and invasion of EC cells by targeting and downregulating THBD expression, and the miR-18a-5p/THBD regulatory pathway might be a therapeutic target. The results of this study may serve as a theoretical basis for related drug development.Sphingomonas sp. Shah is a bacterium that was first isolated from mammalian cell cultures. According to ribotyping data it is very much homologous to the clinically important pathogen Sphingomonas paucimobilis, which has generated pseudo-outbreaks. Using a tissue culture system, Sphingomonas sp. Shah was discovered to induce apoptosis in human lung epithelial carcinoma. Apoptosis of infected cells was determined by numerous criteria including (1) visual alterations in cellular morphology, (2) initiation of nuclear marginalization and chromatin compaction condensation, (3) the attendance of a high percentage of cells with subG1 DNA content, and (4) caspase-3 activation. In the current study we demonstrate the induction of apoptosis in mammalian lung epithelial cells upon infection with Sphingomonas sp. Shah and provide insight into the molecular processes triggering apoptosis.In this era of technology, neurological disorders are the most prevalent disorders in growing population. Alzheimer's and Parkinson's diseases are the most common neurological disorders which are manifested by any abnormality in the structure and functions of neurons present in brain and spinal cord. Exposure to environmental pollution is a serious issue which is associated with high morbidity and mortality rate in the worldwide. Air pollutants are the major contributors to induce the inflammation in lungs and brain which ultimately impairs the normal functioning of CNS. Air pollution persuades CNS pathology by inducing the oxidative stress, activation of microglial cells, neuroinflammation and alteration in permeability of blood brain barrier. Similarly, exposure of heavy metals also exhibits the major and long-lasting effects on brain and causes cognitive dysfunction. Likewise, pesticides have also major influence on the etiology of neurological disorders. Pesticides such as paraquat and rotenone are involved in the pathogenesis of Parkinson's disease. Treatment strategy for environmental pollutants-induced neurological disorders is a challenging task because conventional therapeutics are effective but do not have optimum therapeutic efficacy against such type of disorders. This article addresses how the environmental pollutants are involved in the pathogenesis of neurological disorders and treatment strategies to reduce the occurrence of neurological disorders.This article aims to explore the effects and possible mechanism of miR-543 on small-cell lung carcinoma (SCLC) cells. The respective levels of miR-543 in lung carcinoma tissues, para-cancerous tissues, human normal lung cells MRC-9, and SCLC cells were detected by RT-qPCR. The proliferation, apoptosis, and migration of SCLC cells were detected after the miR-543 level in SCLC cells was altered by miRNA mimics and inhibitors. Erastin2 The levels of apoptosis-related proteins and potential downstream targeted proteins of miR-543 were detected by western blots. The study revealed that KNTC1 was highly expressed in lung carcinoma tissues and SCLC cells (P less then 0.01). It also showed that knockdown of miR-543 can inhibit the proliferation and migration of SCLC cells, induce apoptosis, and increase the level of apoptosis-related proteins. These changes were reversed by the addition of mimics that increased miR-543 levels. The level of miR-543 was positively correlated with the protein expression level of downstream MUC1, β-catenin, and CDC42 in SCLC cells, suggesting that miR-543 may play a role through them.
