As personal contact is greatly reduced, they also create a shared informational landscape, allowing for a shared threat response. This is a difficult task, since truthfulness of content that leads to actionable knowledge is impossible to consistently validate. So, not only that curation of information is rarely congruent with pressing health issues, but digital spaces may also become fertile ground for misinformation and disinformation, contributing to the devastating effects of an infodemic. Digital intermediaries are useful exactly because their representation of reality is not a true construct, but a result of purposely curated information. However, they are active, dynamic epistemological agents with their own logic and aim. In dealing with a pandemic, we should reconsider the ways how our digital informational landscapes are created and sustained. This urges us to consider ethical governance of digital data curation and dissemination, alongside forms of control of the truthfulness and reach of its content. Some of the most fundamental issues in dealing with the COVID-19 pandemic, including the newly available vaccines are reliant on digital information and data sharing among experts, and the role of informing the general public. Selleckchem Rapamycin The need to create a reproducible, valid and truthful informational landscape is paramount, while allowing for free and rational, behavioral individual choices oriented toward preserving and promoting healthy behavior. These are issues at the heart of dealing with any pandemic, as well as a well-organized health care policy.Taking multiple drugs at the same time can increase or decrease each drug's effectiveness or cause side effects. Selleckchem Rapamycin These drug-drug interactions (DDIs) may lead to an increase in the cost of medical care or even threaten patients' health and life. Thus, automatic extraction of DDIs is an important research field to improve patient safety. In this work, a deep neural network model is presented for extracting DDIs from medical texts. This model utilizes a novel attention mechanism for improving the discrimination of important words from others, based on the word similarities and their relative position with respect to candidate drugs. This approach is applied for calculating the attention weights for the outputs of a bi-directional long short-term memory (Bi-LSTM) model in the deep network structure before detecting the type of DDIs. The proposed method was tested on the standard DDI Extraction 2013 dataset and according to experimental results was able to achieve an F1-Score of 78.30 which is comparable to the best results reported for the state-of-the-art methods. A detailed study of the proposed method and its components is also provided.
To discover candidate drugs to repurpose for COVID-19 using literature-derived knowledge and knowledge graph completion methods.

We propose a novel, integrative, and neural network-based literature-based discovery (LBD) approach to identify drug candidates from PubMed and other COVID-19-focused research literature. Our approach relies on semantic triples extracted using SemRep (via SemMedDB). link= Selleckchem Rapamycin We identified an informative and accurate subset of semantic triples using filtering rules and an accuracy classifier developed on a BERT variant. We used this subset to construct a knowledge graph, and applied five state-of-the-art, neural knowledge graph completion algorithms (i.e., TransE, RotatE, DistMult, ComplEx, and STELP) to predict drug repurposing candidates. The models were trained and assessed using a time slicing approach and the predicted drugs were compared with a list of drugs reported in the literature and evaluated in clinical trials. These models were complemented by a discovery pattern-based approtps//github.com/kilicogluh/lbd-covid.
We showed that a LBD approach can be feasible not only for discovering drug candidates for COVID-19, but also for generating mechanistic explanations. Our approach can be generalized to other diseases as well as to other clinical questions. Source code and data are available at https//github.com/kilicogluh/lbd-covid.To create an intracellular niche permissive for its replication, Legionella pneumophila uses hundreds of effectors to target a wide variety of host proteins and manipulate specific host processes such as immune response, and vesicle trafficking. link2 To avoid unwanted disruption of host physiology, this pathogen also imposes precise control of its virulence by the use of effectors called metaeffectors to regulate the activity of other effectors. A number of effector/metaeffector pairs with distinct regulatory mechansims have been characterized, including abrogation of protein modifications, direct modification of the effector and direct binding to the catalytic pocket of the cognate effector. Recently, MesI (Lpg2505) was found to be a metaeffector of SidI, an effector involved in inhibiting host protein translation. Here we demonstrate that MesI functions by inhibiting the activity of SidI via direct protein-protein interactions. We show that this interaction occurs within L. pneumophila and thus interferes with the translocation of SidI into host cells. link3 We also solved the structure of MesI, which suggests that this protein does not have an active site similar to any known enzymes. Analysis of deletion mutants allowed the identification of regions within SidI and MesI that are important for their interactions.Co-occurrence of bacterial infections with type 2 diabetes (T2D) is a global problem. Melioidosis caused by Burkholderia pseudomallei is 10 times more likely to occur in patients with T2D, than in normoglycemic individuals. Using an experimental model of T2D, we observed that greater susceptibility in T2D was due to differences in proportions of infiltrating leucocytes and reduced levels of MCP-1, IFN-γ and IL-12 at sites of infection within 24 h post-infection. However, by 72 h the levels of inflammatory cytokines and bacteria were markedly higher in visceral tissue and blood in T2D mice. In T2D, dysregulated early immune responses are responsible for the greater predisposition to B. pseudomallei infection.Butyrate, propionate, and acetate are short-chain fatty acids (SCFAs) mainly produced by bacterial metabolism in the human gut after dietary fiber intake. SCFAs are considered important for health maintenance by promoting lipid, glucose, and immune homeostasis with an adequate composition of intestinal microbiota, including other beneficial effects like providing protection against colorectal cancer. Therapies with exogenous SCFAs have been proposed to reduce inflammation in intestinal diseases that result from SCFA dysbiosis and cause mucosal inflammation. The aim of this mini-review was to provide an overview of the importance of SCFAs on metabolic and inflammatory processes as well as their role in treating chronic inflammatory disorders.Obesity is a disease characterized by imbalance between energy intake and expenditure, excessive energy store in white adipocytes, but brown and beige adipocytes consume energy to relieve obesity. link2 In this study, we want to explore the role of the histone H3 methyltransferase Ezh2 in the differentiation of white, brown and beige adipocytes with Ezh2 conditional knockout mice (Ezh2flox/floxPrx1-cre) and mouse embryonic fibroblasts (MEFs). The results showed that Ezh2-deficient mice have a leaner phenotype and less white adipose tissues. The morphological changes in the adipose tissue included smaller white adipose tissue depots, white adipocytes with smaller diameter, smaller lipid droplets inside the brown adipocytes and more beige adipocytes in the Ezh2-deficient mice compared with the control. The differentiation markers of white adipocytes in Ezh2 knockout mice decreased; Ucp1 and other browning markers increased in brown and beige adipocytes. The Ezh2 knockout mice could better tolerate cold stimulation, and they can also resist obesity and insulin resistance induced by a high-fat diet. The Ezh2 inhibitor GSK126 could inhibit the differentiation of MEFs into white adipocytes but promote their differentiation into brown/beige adipocytes. The H3K27me3 demethylase Jmjd3/UTX inhibitor GSKJ4 inhibited MEFs' differentiation into brown/beige adipocytes. These results showed that Ezh2 promotes the differentiation of white adipocytes and inhibits the differentiation of brown and beige adipocytes in vivo and in vitro through its methylase activity and this may represent new knowledge for obesity therapeutic strategy.This study aimed to evaluate the concentration of proprotein convertase subtilisin/kexin type-9 (PCSK9) and the activities of paraoxonase 1 in women with and without polycystic ovary syndrome (PCOS). We found significant higher PCSK9, whereas lower high-density lipoprotein concentration in the serum of women with PCOS when compared to the group without PCOS. Also paraoxonase 1 activities were significantly different between women with PCOS than without PCOS. In addition, the women with PCOS and insulin resistance had higher concentrations of PCSK9 than women with PCOS and insulin sensitivity. Higher PCSK9 concentration in the group with PCOS could be also associated with hormones concentrations. Changes in paraoxonase 1 activities and lipid profile parameters as well as higher concentration of PCSK9 in the group of women with PCOS could be associated with metabolism disorders, but due to the small clinical sample size, the study should be continued.To explore the relationship of oxidative stress and TGF-β 1/Smad3 pathway in the inhibition of osteoblast mineralization by copper chloride (CuCl2), the osteoblasts were treated with CuCl2 (0, 50 μM, 100 μM, 150 μM CuCl2 5H2O) for 24 h. We found that Cu impaired the osteoblast structure, inhibited the glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) activities, alkaline phosphatase (ALP) content, mRNA expression of collagen I (COL-I), osteocalcin (OCN), insulin-like growth factor I (IGF-I), bone morphogenetic protein-2 (BMP-2), transforming growth factor β1 (TGF-β1) and core-binding factor α1 (Cbfα1), promoted the reactive oxygen species (ROS) production, inactivated the TGF-β1/Smad3 pathway. It indicates that the inactivated TGF-β1/Smad3 pathway leads to osteoblast impairment by CuCl2. It will contribute to clarify the influence of CuCl2 on the osteoblast mineralization.Circular RNAs are produced from back-splicing of exons of precursor mRNAs (pre-mRNAs). link3 The sequences of exons in circular RNAs are identical to their linear cognate mRNAs, but the circular format may confer constraints on their folding and conformation, leading to potentially different functions from their linear RNA cognates. Here, we describe experimental and computational steps that optimize the selective 2'-hydroxyl acylation analyzed by primer extension and mutational profiling (SHAPE-MaP) to probe circular RNA secondary structure at single-nucleotide resolution in living cells.
