Dietary Antioxidants inside the Mediterranean Diet plan.
Tea is one of the three most widely consumed beverages in the world, not only because of its unique flavor but also due to its various health benefits. The bioactive components in tea, such as polyphenols, polysaccharides, polypeptides, pigments, and alkaloids, are the main contributors to its health functions. Based on epidemiological surveys, the consumption of tea and its compounds in daily life has positive effects on cardiovascular diseases, cancers, hepatopathy, obesity, and diabetes mellitus. In experimental studies, the antioxidant, anti-inflammatory, anti-cancer, anti-obesity, cardiovascular protective, liver protective, and hypoglycemic activities of tea and the related mechanisms of action have been widely investigated. The regulation of several classical signaling pathways, such as nuclear factor-κB (NF-κB), AMP activated protein kinase (AMPK), and wingless/integrated (Wnt) signaling, is involved. Clinical trials have also demonstrated the potential of tea products to be applied as dietary supplements and natural medicines. In this paper, we reviewed and discussed the recent literature on the health benefits of tea and its compounds, and specifically explored the molecular mechanisms involved.Mycoplasma genitalium is an obligate intracellular bacterium that is responsible for several sexually transmitted infections, including non-gonococcal urethritis in men and several inflammatory reproductive tract syndromes in women. Here, we applied subtractive genomics and reverse vaccinology approaches for in silico prediction of potential vaccine and drug targets against five strains of M. genitalium. We identified 403 genes shared by all five strains, from which 104 non-host homologous proteins were selected, comprising of 44 exposed/secreted/membrane proteins and 60 cytoplasmic proteins. Based on the essentiality, functionality, and structure-based binding affinity, we finally predicted 19 (14 novel) putative vaccine and 7 (2 novel) candidate drug targets. The docking analysis showed six molecules from the ZINC database as promising drug candidates against the identified targets. Altogether, both vaccine candidates and drug targets identified here may contribute to the future development of therapeutic strategies to control the spread of M. genitalium worldwide.OTOG encodes for otogelin, a component of the tectorial membrane. This gene is associated with nonprogressive mild-to-moderate hearing loss. However, no studies have yet identified the association between OTOG variation and severe-to-profound hearing loss. Therefore, to address this issue, a family-based whole-exome sequencing strategy (WES) was carried out. Two unrelated Iranian families with non-syndromic hearing loss were identified, and WES was conducted on one selected candidate from each family. As a result, a rare homozygous missense variant, OTOG (c.C2383Tp.R795C), was detected in both of the subjected probands, and segregation analysis confirmed the c.C2383T variant in seven cases of severe-to-profound hearing loss. Additionally, the results from the protein modeling demonstrated that the altered position of a few disulfide bonds in the TIL domain may have a deleterious impact on protein stability and normal functionality. In conclusion, it seems that the homozygosity of the OTOG c.C2383T mutation sheds light on hearing loss pathobiology. Nevertheless, further studies are required to unravel the precise function of OTOG mutation, which is potentially associated with severe-to-profound hearing loss.Angiostrongylus vasorum is an emerging parasitic nematode of canids and causes respiratory distress, bleeding, and other signs in dogs. Despite its clinical importance, the molecular toolbox allowing the study of the parasite is incomplete. To address this gap, we have sequenced its nuclear genome using Oxford nanopore sequencing, polished with Illumina reads. The size of the final genome is 280 Mb comprising 468 contigs, with an N50 value of 1.68 Mb and a BUSCO score of 93.5%. Ninety-three percent of 13,766 predicted genes were assigned to putative functions. Three folate carriers were found exclusively in A. vasorum, with potential involvement in host coagulopathy. A screen for previously identified vaccine candidates, the aminopeptidase H11 and the somatic protein rHc23, revealed homologs in A. vasorum. The genome sequence will provide a foundation for the development of new tools against canine angiostrongylosis, supporting the identification of potential drug and vaccine targets.Epitranscriptomics involves functionally relevant biochemical modifications of RNA taking place at the transcriptome level without a change in the sequence of ribonucleotides. Several types of modifications that affect the processing and function of differentRNA types have been reported. Methylation at N6 of Adenosine called m6A is one such modification, quite widespread in occurrence and reported in snRNAs, lncRNAs, circRNAs, rRNAs, miRNAs, and most abundantly, in mRNAs. The significant implications of m6A in various types of cancers are being widely recognized. Here, we give a brief about the enzymes that install the m6A modification (= m6A writers), that remove it (= m6A erasers) and certain RNA binding proteins (= m6A readers) which affect the fate of the m6A-containing RNA by recruiting various proteins. We also discuss the relevance of m6A in ncRNAs in various cancer types, followed by a discussion on the role of m6A of mRNA and ncRNA in lung cancer.Cleft palate is one of the most frequent craniofacial malformation birth defects. Miniature pigs (Sus scrofa) are a valuable alternative large animal model to explore human palate development. Presently, the microRNA (miRNA) expression profiles in miniature pigs during palatogenesis from embryonic day (E) 30 to 50 were identified. A total of 2044 known miRNAs and 192 novel miRNAs were identified. The functional characteristics of their potential target genes were identified using Gene Ontology function and Kyoto Encyclopedia of Genes and Genomes pathway analysis. MiRNAs displayed diverse expression levels among the different stages. Using Short Time-series Expression Miner software to investigate the expression patterns of miRNAs from E30-50, all miRNAs were clustered into 20 profiles. The profiles showing miRNAs expression decreased (profile 0)/increased (profile 19) from E30-50 were the main patterns during palatogenesis. Hub genes of four significant modules were identified by weighted correlation network analysis, including ssc-miR-98, ssc-miR-27a_R + 1, and ssc-miR-150, etc. which might be novel potential targets for regulating palate development. The data are expected to improve the understanding of palate development and the etiology of cleft palate in further studies.Gamma-glutamyltransferase (GGT) and keratins (KRT) are key factors in regulating tumor progression rely on emerging evidence. However, the prognostic values of GGT and KRT isoforms and their regulation patterns at transcriptional and post-transcriptional levels have been rarely studied. In this study, we aimed to identify cooperative prognostic biomarker signature conducted by GGT and KRT genes for overall survival prediction and discrimination in patients with low-grade glioma (LGG) and glioblastoma multiforme (GBM). To this end, we employed a differential expression network analysis on LGG-NORMAL, GBM-NORMAL, and LGG-GBM datasets. Then, all the differentially expressed genes related to a GO term "GGT activity" were excluded. After that, for obtained potential biomarkers genes, differentially expressed lncRNAs were used to detect cis-regulatory elements (CREs) and trans-regulatory elements (TREs). To scrutinize the regulation on the cytoplasm, potential interactions between these biomarker genes and DElncRNAs were predicted. Our analysis, for the first time, revealed that GGT6, KRT33B, and KRT75 in LGG, GGT2, and KRT75 in GBM and KRT75 for LGG to GBM transformation tumors can be novel cooperative prognostic biomarkers that may be applicable for early detection of LGG, GBM, and LGG to GBM transformation tumors. Consequently, KRT75 was the most important gene being regulated at both transcriptional and post-transcriptional levels significantly. Furthermore, CREs and their relative genes were coordinative up-regulated or down-regulated suggesting CREs as regulation points of these genes. In the end, up-regulation of most DElncRNAs that had physical interaction with target genes pints out that the transcripted genes may have obstacles for translation process.Pregnancy alters B cell development and function. B cell activation is initiated by antigens binding to the BCR leading to B cell survival, proliferation, antigen presentation and antibody production. We performed a genome-wide transcriptome profiling of splenic B cells from pregnant (P) and non-pregnant (NP) mice and identified 1136 genes exhibiting differential expression in B cells from P mice (625 up- and 511 down-regulated) compared to NP animals. In silico analysis showed that B cell activation through BCR seems to be lowered during pregnancy. RT-qPCR analysis confirmed these data. BMS-986365 price Additionally, B cells from pregnant women stimulated in vitro through BCR produced lower levels of inflammatory cytokines compared to non-pregnant women. Our results suggest that B cells acquire a state of hypo-responsiveness during gestation, probably as part of the maternal immune strategy for fetal tolerance but also open new avenues to understand why pregnant women are at highest risk for infections.A noninferiority trial is designed to show that the new treatment is not unacceptably worse than the standard treatment by more than a predefined noninferiority margin. These trials are typically performed when standard placebo-controlled trials are considered to be unethical or impractical and the new treatment offers advantages over the existing standard treatment in terms of safety, convenience, or cost. Given that noninferiority trials are being performed with increasing frequency in cardiovascular applications, it is important to understand their complex trial design and analysis. This narrative review aims to provide readers with a detailed perspective on the goals, characteristics, design, and analysis of noninferiority trials. Trials designed to show noninferiority require an appropriate reference population, a proven standard treatment and dose, an appropriate margin of noninferiority that is statistically justifiable (based on historical placebo-controlled trials evaluating standard treatment effect) and clinically reasonable (choosing the fraction of the effect of the standard drug that should be "preserved" by the new drug), a high level of adherence to treatment, and adequate statistical power to reliably conclude that a treatment is truly noninferior and therefore effective. The merits and pitfalls of noninferiority trials, with representative contemporary cardiovascular clinical trials in interventional cardiology, cardiac surgery, and atrial fibrillation management as exemplars, are described. The key issues that challenge the design, conduct, analysis, interpretation, and implementation of these trials are discussed, and a variety of ways to identify and mitigate key errors are recommended to allow for optimal evaluation of noninferiority trials conducted in cardiovascular medicine.
