Myelodysplastic syndrome (MDS) is a malignant hematopoietic stem cell disorder that frequently evolves into acute myeloid leukemia (AML). Patients with MDS are prone to infectious complications, in part due to the presence of severe neutropenia and/or neutrophil dysfunction. However, not all patients with neutropenia become infected, suggesting that other immune cells may compensate in these patients. Monocytes are also integral to immunologic defense; however, much less is known about monocyte function in patients with MDS...

MicroRNAs are short endogenous noncoding RNAs that play pivotal roles in a diverse range of cellular processes. The miR-181 family is important in T cell development, proliferation, and activation. In this study, we have identified BRK1 as a potential target of miR-181c using a dual selection functional assay and have showed that miR-181c regulates BRK1 by translational inhibition. Given the importance of miR-181 in T cell function and the potential role of BRK1 in the involvement of WAVE2 complex and actin polymerization in T cells, we therefore investigated the influence of miR-181c-BRK1 axis in T cell function...

BACKGROUND: Evidence-based medicine is the application of research findings to inform individual clinical decisions. There is a tension-both philosophical and practical-between the average result from a population study and the circumstances and needs of an individual patient. This personal account of "evidence-based" trauma care illustrates and explores this tension. THE CASE: The author, a keen athlete, describes her experience of a high-impact cycle accident that led to limb fractures (which were diagnosed and treated according to evidence-based guidelines) and also an occult injury to the cervical spine (which was not diagnosed at the time)...

BACKGROUND: Mycobacterium tuberculosis (TB) is a common pathogen worldwide, and it may cause significant infection after solid organ transplantation (SOT). We reviewed all reported TB cases to provide an update on its epidemiology, clinical presentation, management and outcome after SOT. METHODS: MEDLINE, EMBASE, and OVID were reviewed from January 1, 1998 to Dec 31, 2016 using key words tuberculosis and solid organ transplant or transplantation. RESULTS: There were 187 publications reporting 2082 cases of TB among kidney (n=1719), liver (n=253), heart (n=77), lung (n=25), and kidney-pancreas (n=8) recipients...

PREMISE OF THE STUDY: Our current understanding of flowering plant phylogeny provides an excellent framework for exploring various aspects of character evolution through comparative analyses. However, attempts to synthesize this phylogenetic framework with extensive morphological data sets have been surprisingly rare. Here, we explore character evolution in Asteridae (asterids), a major angiosperm clade, using an extensive morphological data set and a well-resolved phylogeny. METHODS: We scored 15 phenotypic characters (spanning chemistry, vegetative anatomy, and floral, fruit, and seed features) across 248 species for ancestral state reconstruction using a phylogenetic framework based on 73 plastid genes and the same 248 species...

BACKGROUND: The cellular and molecular mechanisms for aged-associated delay of cutaneous wound healing are still not well understood. Our previous results show that miR-21 plays key roles during skin wound healing. We presumed that dysregulation of miR-21 may involve in aged-associated defects in wound healing and miR-21 may be one potential therapeutic target to ameliorate wound defects in elderly subjects. METHODS: Circular full thickness excisional wounds were made on the dorsal skin of young (2-month-old) and aged (12-month-old) female mice...

Enantiospecific total syntheses of (+)-hapalindole H, (-)-12-epi-hapalindole U, formal synthesis of (+)-hapalindole Q and (+)-12-epi-fischerindole U isothiocyanate have been described. Key steps of our approach feature expedient, highly regio- and diastereoselective Lewis acid catalyzed Friedel-Crafts reaction of indole with cyclic allylic alcohols and intramolecular reductive Heck reaction. Efficiency of the synthetic route also relies on an alkynyl aluminate complex driven regioselective nucleophilic epoxide opening from sterically hindered site...

OBJECTIVES: Dental tissue-derived mesenchymal stem cells (MSCs)-mediated pulp-dentin regeneration is considered a potential approach for the regeneration of damaged teeth. Enhancing MSC-mediated pulp-dentin regeneration is based on an understanding of the molecular mechanisms underlying directed cell differentiation process. Histone demethylation enzyme, lysine demethylase 1A (KDM1A) can regulate the differentiation of some MSCs, but its role in dental tissue-derived MSCs is unclear. MATERIAL AND METHODS: We obtained SCAPs from immature teeth...

Research using the Stop Signal Task employing an adaptive algorithm to accommodate individual differences often report inferior performance on the task in individuals with ADHD, OCD, and substance use disorders compared to non-clinical controls. Furthermore, individuals with deficits in inhibitory control tend to show reduced neural activity in key inhibitory regions during successful stopping. However, the adaptive algorithm systematically introduces performance-related differences in objective task difficulty that may influence the estimation of individual differences in stop-related neural activity...

OBJECTIVE: Distress screening programs aim to ensure appropriate psycho-oncological support for cancer patients, but many eligible patients do not use these services. To improve distress management, we need to better understand patients' supportive care needs. In this paper, we report the first key finding from a longitudinal study that focused on patients' intentions to use psycho-oncological support, and its association with distress and uptake of the psycho-oncology service. METHODS: We conducted a prospective, observational study in an Oncology Outpatient Clinic and assessed distress, intention to use psycho-oncological support, and uptake of the psycho-oncology service using the Distress Thermometer (DT), a semi-structured interview, and hospital records...

OBJECTIVE: Very few reports have previously described spondylodiscitis as a potential complication of endovascular aortic aneurysm repair (EVAR). We present to our knowledge the first case series of spondylodiscitis following EVAR based on our institution's experience over an 11-year period. Particular attention is paid to the key imaging features and challenges encountered when performing spinal imaging in this complex patient group. MATERIALS AND METHODS: Of 1,847 patients who underwent EVAR at our institution between January 2006 and January 2017, a total of 9 patients were identified with imaging features of spondylodiscitis (0...

Public partners play a key role when we want to improve nutrition quality. They will not succeed, when they try to achieve the goal alone or tend to dominate other players. In their responsibility for common interests it is up to public partners to moderate and facilitate the multi-stakeholder and multi-sectorial dialogue to improve nutrition quality. It is up to public partners to establish clear legal and structural guidelines aiming to bring all partners together, to avoid conflicts of interests and, above all, establish conditions, in which consumers are sufficiently informed about food and nutrition, so that they are motivated, empowered, and adequately protected to take their own responsible decisions...

Conducting hydromorphological assessments for evaluating the ecological status of rivers is a key requirement of the Directive 2000/60/EC (Water Framework Directive - WFD) within European Union (EU) Member States. This paper aims at understanding how this requirement was implemented, through an original comparative review of methodologies for rivers' hydromorphological assessment in three EU Member States, which joined the EU at different times, and with many differences in terms of hydrographic features, socio-economic and water management systems: France, Romania, and Croatia...

Connectivity in intrinsically connected networks (ICNs) may predict individual differences in cognition and behavior. The drastic alterations in socioemotional awareness of patients with behavioral variant frontotemporal dementia (bvFTD) are presumed to arise from changes in one such ICN, the salience network (SN). We examined how individual differences in SN connectivity are reflected in overt social behavior in healthy individuals and patients, both to provide neuroscientific insight into this key brain-behavior relationship, and to provide a practical tool to diagnose patients with early bvFTD...

Hypocrellin A (HA) is a major bioactive perylenequinone from the fruiting body of Shiraia bambusicola used for the treatment of skin diseases and developed as a photodynamic therapy (PDT) agent against cancers and viruses. The mycelial culture of S. bambusicola under dark is a biotechnological alternative for HA production but with low yield. In this study, light and dark conditions were investigated to develop effective elicitation on HA production in the cultures. Our results showed the constant light at 200 lx stimulated HA production without any growth retardation of mycelia...

BACKGROUND: We have previously demonstrated that the receptor for advanced glycation end products (RAGE)/β-catenin axis plays a vital role in regulating airway inflammation and airway remodeling in a toluene diisocyanate (TDI)-induced murine asthma model. However, the exact mechanism of β-catenin activation remains unclear. Given that phosphorylation of the low-density lipoprotein receptor-related protein 6 (Lrp6) is a key step in mediating β-catenin stabilization in canonical wnt/β-catenin signaling, we explored the possible relationship between RAGE and Lrp6 in regulating β-catenin stabilization in TDI-induced asthma...

Rheumatoid arthritis (RA) is a systemic inflammatory and autoimmune disease. In this research, we estimated the protective effects of Dihydromyricetin (DMY) on RA induced by Complete Freund's Adjuvant (CFA). We found that DMY effectively relieved rheumatoid arthritis symptoms, such as body weight change, paw swelling and rheumatoid arthritis scores. In addition, we also observed that DMY significantly lowered the immune organ indexes (including thymus and spleen) and exhibited the anti-inflammatory effect in CFA-induced rheumatoid arthritis...

Multidrug resistance (MDR) is a tendency in which cells become resistant to structurally and mechanistically unrelated drugs, which is mediated by P-glycoprotein (P-gp). It is one of the noteworthy problems in cancer therapy. As one of the most important drugs in cancer therapy, doxorubicin has not good effectiveness if used independently. So targeting the P-gp protein is one of the key points to solve the MDR. Three series of furan derivatives containing tetrahydroquinoline or tetrahydroisoquinoline were designed and synthesized as P-gp inhibitors in this paper...
