A subsidiary aim was to investigate the anti-inflammatory effect of any identified compound. METHODOLOGY The Gene Expression Omnibus (GEO) database was searched for microarray datasets assessing odontogenic differentiation of human DPCs. An odontogenic gene expression signature was generated by differential expression analysis. The statistical significant connectivity map (ssCMap) method was used to identify compounds with a highly correlating gene expression pattern. DPCs were treated with the compound identified and osteo/odontogenic differentiation was assessed by alizarin red staining, alkaline phosphatase activity and expression of osteo/odontogenic genes ALPL, RUNX2, COL1A1, DSPP, DMP1 and SPP1 by RT-PCR. The anti-inflammatory effect of the compound was assessed using an ex vivo pulpitis model and cytokine n of DPCs. Aspirin was shown to induce odontogenic differentiation in DPCs in vitro and this, together with its anti-inflammatory effects, makes it a potential candidate for vital pulp therapies.

Postoperative pain is a risk factor for persistent or chronic pain unless treated effectively. There are only a few studies that have assessed the use of opioid-containing drugs after gynecological surgery and most of these usually have a short follow-up period. The aim of this study was to identify risk-factors for long-term use of prescription opioid drugs following hysterectomy. MATERIAL AND METHODS We performed a nationwide cohort study based on prospectively collected data. Information from two population-based registers, the Swedish National Quality Register of Gynecological Surgery and the Swedish National Drug Register, was linked. The study population consisted of women with benign disease undergoing a total hysterectomy from 1 January 2012 until 31 December 2015. To identify long-term changes in prescription of opioids, individual data were collected from 1 year prior to to opioids after hysterectomy is common and is, among other risk factors, strongly associated with preoperative use of opioids, as well as psychoactive drugs and adenomyosis. To avoid opioid misuse disorders among women at risk for long-term opioid drug prescriptions after hysterectomy, further studies and strategies are needed. © 2020 Nordic Federation of Societies of Obstetrics and Gynecology.All infective bacterial species need to conquer the innate immune system in order to colonize and survive in their hosts. The human respiratory pathogens Haemophilus influenzae and Moraxella catarrhalis are no exceptions and have developed sophisticated mechanisms to evade complement-mediated killing. Both bacterial species carry lipooligosaccharides preventing complement attacks and attract and utilize host complement regulators C4b binding protein and factor H to inhibit the classical and alternative pathways of complement activation, respectively. In addition, the regulator of the terminal pathway of complement activation, vitronectin, is hijacked by both bacteria. An array of different outer membrane proteins (OMP) in H. influenzae and M. catarrhalis simultaneously binds complement regulators, but also plasminogen. Several of the bacterial complement-binding proteins are important adhesins and contain highly conserved regions for interactions with the host. Thus, some of the OMP are viable targets for new therapeutics, including vaccines aimed at preventing respiratory tract diseases such as otitis media in children and exacerbations in patients suffering from chronic obstructive pulmonary disease. © 2020 The Author.

One Myc inhibitor, Omomyc, has limited cellular and in vivo activity. Here, we report a mini-protein, referred to as Mad, which is derived from the cellular Myc antagonist Mxd1. Mad localizes to the nucleus in cells and is 10-fold more potent than Omomyc in inhibiting Myc-driven cell proliferation. Similar to Mxd1, Mad also interacts with Max, the binding partner of Myc, and with the nucleolar upstream binding factor. Mad binds to E-Box DNA in the promoters of Myc target genes and represses Myc-mediated transcription to a greater extent than Omomyc. Overall, Mad appears to be more potent than Omomyc both in vitro and in cells. © 2020 Federation of European Biochemical Societies.BACKGROUND Low health literacy is associated with poor health outcomes in many chronic diseases and may have an important role in determining surgical outcomes. This study aims to comprehensively review the current state of science on adult health literacy in surgery and to identify knowledge gaps for future research. METHODS Using the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) guidelines, a systematic search was conducted to identify all studies from January 2002 through May 2018 that used validated instruments to assess health literacy among adult patients undergoing surgery. Studies were assessed for quality using the Newcastle-Ottawa scale and evaluated on findings by their focus on identifying health literacy levels, understanding associations with surgical outcomes, and/or developing interventions to address low health literacy. KEY RESULTS There were 51 studies on health literacy with data from 22,139 patients included in this review. Low health literacy was present in more than one-third of surgical patients (34%, interquartile range 16%-50%).
