Sympathetic activity may correlate with an adaptive mechanism to reduce the severity of chronic colitis. The Winnie and Winnie-Prolapse mouse models of moderate and severe chronic colitis are well suited to examine the pathophysiology of progressive chronic intestinal inflammation.Lenalidomide recently was shown to have clinical activity in patients with human immunodeficiency virus-associated Kaposi sarcoma. Immunomodulatory imine drugs thus provide another tool in the treatment of this challenging neoplasm. See related article by Reid et al., p. 2646.Epidemiological trends have led to a growing consensus that diet plays a central role in the etiopathogenesis of inflammatory bowel diseases (IBD). A Western diet high in ultra-processed foods has been associated with an increased prevalence of IBD worldwide. Much attention has focused on components of the Western diet, including the high fat content, lack of fiber, added sugars, and use of additives, such as carrageenan and other emulsifiers. Less attention has been paid to the impact of high salt intake, an integral component of ultra-processed foods, which has increased dramatically in the US diet over the past 50 years. We review a growing body of literature linking the rise in dietary salt intake with the epidemiology of IBD, increased consumption of salt as a component of ultra-processed foods, high salt intake and imbalances in immune homeostasis, the effects of a high-salt diet on other inflammatory disorders, salt's impact on animal colitis models, salt as an underrecognized component in diet modification-induced remission of IBD, and directions for future investigation.

Emerging technologies (eg, wearable devices) have made it possible to collect data directly from individuals (eg, time-series), providing new insights on the health and well-being of individual patients. Broadening the access to these data would facilitate the integration with existing data sources (eg, clinical and genomic data) and advance medical research. Compared to traditional health data, these data are collected directly from individuals, are highly unique and provide fine-grained information, posing new privacy challenges. In this work, we study the applicability of a novel privacy model to enable individual-level time-series data sharing while maintaining the usability for data analytics.

We propose a privacy-protecting method for sharing individual-level electrocardiography (ECG) time-series data, which leverages dimensional reduction technique and random sampling to achieve provable privacy protection. We show that our solution provides strong privacy protection against an informed adversarial model while enabling useful aggregate-level analysis.

We conduct our evaluations on 2 real-world ECG datasets. Our empirical results show that the privacy risk is significantly reduced after sanitization while the data usability is retained for a variety of clinical tasks (eg, predictive modeling and clustering).

Our study investigates the privacy risk in sharing individual-level ECG time-series data. We demonstrate that individual-level data can be highly unique, requiring new privacy solutions to protect data contributors.

The results suggest our proposed privacy-protection method provides strong privacy protections while preserving the usefulness of the data.

This species is used as a traditional Tibetan medicine because of its rich gentiopicroside constituents. Here, we generate a high-quality, chromosome-level genome of G. dahurica with a total length of 1,416.54 Mb. Comparative genomic analyses showed that G. dahurica shared one whole-genome duplication (WGD) event with Gelsemium sempervirens of the family Gelsemiaceaei and had one additional species-specific WGD after the ancient whole-genome triplication with other eudicots. Further transcriptome analyses identified numerous enzyme coding genes and the transcription factors related to gentiopicroside biosynthesis. GSK-3 inhibitor A set of candidate cytochrome P450 genes were identified for being involved in biosynthetic shifts from swertiamarin to gentiopicroside. Both gene expressions and the contents measured by high-performance liquid chromatography indicated that the gentiopicrosides were mainly synthesized in the rhizomes with the highest contents. In addition, we found that two above-mentioned WGDs, contributed greatly to the identified candidate genes involving in gentiopicroside biosynthesis. The first reference genome of Gentianaceae we generated here will definitely accelerate evolutionary, ecological, and pharmaceutical studies of this family.

Tofacitinib is an oral, small molecule JAK inhibitor for the treatment of ulcerative colitis (UC). These post hoc analyses assessed associations between C-reactive protein (CRP), partial Mayo score (PMS), and efficacy outcomes during tofacitinib induction in UC.

Patients received tofacitinib 10mg twice daily (BID) in an 8-week, phase 2 induction study and 2 identical, 8-week, phase 3 induction studies (OCTAVE Induction 1&2); induction nonresponders (IndNR) received an additional 8 weeks of tofacitinib 10mg BID in an open-label, long-term extension study. Associations between CRP and PMS, and efficacy outcomes (clinical response, clinical remission, endoscopic improvement, and endoscopic remission) were analyzed using univariate and multivariable logistic regression and receiver operating characteristic curves.

Changes from baseline in the logarithm of CRP ([log]CRP) and PMS at week 4 were associated with clinical response at week 8 (univariate per unit, odds ratio [OR], 0.55 [95% confidence interval65763;NCT01458951;NCT01470612.Standardized data definitions are essential for monitoring and benchmarking the quality of care and patient outcomes in observational studies and randomized controlled trials. There are no contemporary pan-European data standards for the acute coronary syndrome (ACS) and percutaneous coronary intervention (PCI). The European Unified Registries for Heart Care Evaluation and Randomised Trials (EuroHeart) project of the European Society of Cardiology (ESC) aimed to develop such data standards for ACS and PCI. Following a systematic review of the literature on ACS and PCI data standards and evaluation of contemporary ACS and PCI registries, we undertook a modified Delphi process involving clinical and registry experts from 11 European countries, as well as representatives from relevant ESC Associations, including the European Association of Percutaneous Cardiovascular Interventions (EAPCI) and Acute CardioVascular Care (ACVC). This resulted in final sets of 68 and 84 'mandatory' variables and several catalogues of optional variables for ACS and PCI, respectively. Data definitions were provided for these variables, which have been programmed as the basis for continuous registration of individual patient data in the online EuroHeart IT platform. By means of a structured process and the interaction with major stakeholders, internationally harmonized data standards for ACS and PCI have been developed. In the context of the EuroHeart project, this will facilitate country-level quality of care improvement, international observational research, registry-based randomized trials, and post-marketing surveillance of devices and pharmacotherapies.

Lightless caves can harbour a wide range of living organisms. Cave animals have evolved a set of morphological, physiological, and behavioural adaptations known as troglomorphisms, enabling their survival in the perpetual darkness, narrow temperature and humidity ranges, and nutrient scarcity of the subterranean environment. In this study, we focused on adaptations of skull shape and sensory systems in the blind cave salamander, Proteus anguinus, also known as olm or simply proteus-the largest cave tetrapod and the only European amphibian living exclusively in subterranean environments. This extraordinary amphibian compensates for the loss of sight by enhanced non-visual sensory systems including mechanoreceptors, electroreceptors, and chemoreceptors. We compared developmental stages of P. anguinus with Ambystoma mexicanum, also known as axolotl, to make an exemplary comparison between cave- and surface-dwelling paedomorphic salamanders.

We used contrast-enhanced X-ray computed microtomography for the 3D s.Over the past 50 years, the nematode worm Caenorhabditis elegans has become established as one of the most powerful and widely used model organisms. This article explores the origins and subsequent history of a generally accepted system for gene naming and genetic nomenclature in C. elegans.The Alliance of Genome Resources (the Alliance) is a combined effort of 7 knowledgebase projects Saccharomyces Genome Database, WormBase, FlyBase, Mouse Genome Database, the Zebrafish Information Network, Rat Genome Database, and the Gene Ontology Resource. The Alliance seeks to provide several benefits better service to the various communities served by these projects; a harmonized view of data for all biomedical researchers, bioinformaticians, clinicians, and students; and a more sustainable infrastructure. The Alliance has harmonized cross-organism data to provide useful comparative views of gene function, gene expression, and human disease relevance. The basis of the comparative views is shared calls of orthology relationships and the use of common ontologies. The key types of data are alleles and variants, gene function based on gene ontology annotations, phenotypes, association to human disease, gene expression, protein-protein and genetic interactions, and participation in pathways. The information is presented on uniform gene pages that allow facile summarization of information about each gene in each of the 7 organisms covered (budding yeast, roundworm Caenorhabditis elegans, fruit fly, house mouse, zebrafish, brown rat, and human). The harmonized knowledge is freely available on the alliancegenome.org portal, as downloadable files, and by APIs. We expect other existing and emerging knowledge bases to join in the effort to provide the union of useful data and features that each knowledge base currently provides.Biological interpretation of a large amount of gene or protein data is complex. Ontology analysis tools are imperative in finding functional similarities through overrepresentation or enrichment of terms associated with the input gene or protein lists. However, most tools are limited by their ability to do ontology-specific and species-limited analyses. Furthermore, some enrichment tools are not updated frequently with recent information from databases, thus giving users inaccurate, outdated or uninformative data. Here, we present MOET or the Multi-Ontology Enrichment Tool (v.1 released in April 2019 and v.2 released in May 2021), an ontology analysis tool leveraging data that the Rat Genome Database (RGD) integrated from in-house expert curation and external databases including the National Center for Biotechnology Information (NCBI), Mouse Genome Informatics (MGI), The Kyoto Encyclopedia of Genes and Genomes (KEGG), The Gene Ontology Resource, UniProt-GOA, and others. Given a gene or protein list, MOET analysis identifies significantly overrepresented ontology terms using a hypergeometric test and provides nominal and Bonferroni corrected P-values and odds ratios for the overrepresented terms.
