Oxyprenylated compounds (i.e., ferulic acid and coumarin derivatives) demonstrate neuroprotection and anticancer properties as reported in previous studies. We have tested the affinity of oxyprenylated ferulic acid (1-4) and umbelliferone derivatives (5-11) to melatonin receptors as well as their antiproliferation and antimigratory properties against breast cancer (BC) cell lines. All the compounds except for ferulic acid, boropinic acid, and umbelliferone had binding affinities to melatonin receptors in the nM to μM range, and both auraptene and umbellinprenin reduced BC cell proliferation and migration in phenotypically diverse BC including triple negative...

Innovative migrant-friendly tools are needed to assist health personnel manage the high number of pregnancies within reception centers. This study tests functionality and acceptability of a new mHealth system in providing antenatal care amongst migrants. The study, carried out between 2014 and 2016, involved 150 pregnant women residing in the largest European migrant reception center in Sicily. A ticket tracking system assessed the system's functionality and a questionnaire assessed women's acceptability. The system facilitated the collection of clinical data, enabling the creation of electronic patient records and identifying 10% of pregnancies as high-risk...

Rhythmic non-invasive brain stimulations are promising tools to modulate brain activity by entraining neural oscillations in specific cortical networks. The aim of the study was to assess the possibility to influence the neural circuits of the wake-sleep transition in awake subjects via a bilateral transcranial alternating current stimulation at 5 Hz (θ-tACS) on fronto-temporal areas. 25 healthy volunteers participated in two within-subject sessions (θ-tACS and sham), one week apart and in counterbalanced order...

Mammalian cells must integrate environmental cues to determine coherent physiological responses. The transcription factors Myc and YAP-TEAD act downstream from mitogenic signals, with the latter responding also to mechanical cues. Here, we show that these factors coordinately regulate genes required for cell proliferation. Activation of Myc led to extensive association with its genomic targets, most of which were prebound by TEAD. At these loci, recruitment of YAP was Myc-dependent and led to full transcriptional activation...

Activity of the APOBEC enzymes has been linked to specific mutational processes in human cancer genomes. A germline APOBEC3A/B deletion polymorphism is associated with APOBEC-dependent mutational signatures, and the deletion allele has been reported to confer an elevated risk of some cancers in Asian populations, while the results in European populations, so far, have been conflicting. We genotyped the APOBEC3A/B deletion polymorphism in a large population based sample consisting of 11,106 Caucasian (Norwegian) individuals, including 7,279 incident cancer cases (1,769 breast- , 1,360 lung-, 1,585 colon-, and 2,565 prostate cancer) and a control group of 3,827 matched individuals without cancer (1,918 females and 1,909 males) from the same population...

Untreated wastewater is a risk factor for the spread of antibiotic resistance in the environment. However, little is known about the contribution of untreated wastewater to the burden of antibiotic resistance in the Nigerian environment. In this study, a total of 143 ceftazidime-/cefpodoxime-resistant bacteria isolated from untreated wastewater and untreated wastewater-contaminated surface and groundwater in Nigeria were screened for extended-spectrum β-lactamase (ESBL) genes, integrons and integron gene cassettes by PCR...

BACKGROUND: Inclusion health focuses on people in extremely poor health due to poverty, marginalisation, and multimorbidity. We aimed to review morbidity and mortality data on four overlapping populations who experience considerable social exclusion: homeless populations, individuals with substance use disorders, sex workers, and imprisoned individuals. METHODS: For this systematic review and meta-analysis, we searched MEDLINE, Embase, and the Cochrane Library for studies published between Jan 1, 2005, and Oct 1, 2015...

Inclusion health is a service, research, and policy agenda that aims to prevent and redress health and social inequities among the most vulnerable and excluded populations. We did an evidence synthesis of health and social interventions for inclusion health target populations, including people with experiences of homelessness, drug use, imprisonment, and sex work. These populations often have multiple overlapping risk factors and extreme levels of morbidity and mortality. We identified numerous interventions to improve physical and mental health, and substance use; however, evidence is scarce for structural interventions, including housing, employment, and legal support that can prevent exclusion and promote recovery...

Over recent years, many RNA viruses have been "re-discovered", including life-threatening flaviviruses, such as Dengue, Zika, and several encephalitis viruses. Since no specific inhibitors are currently available to treat these infections, there is a pressing need for new therapeutics. Among the flaviviral proteins, NS5 RNA-dependent RNA polymerase (RdRp) represents a validated target being essential for viral replication and it has no human analog. To date, few NS5 RdRp inhibitor chemotypes have been reported and no inhibitors are currently in clinical development...

Mechanisms how colorectal cancer (CRC) cells penetrate blood micro-vessel endothelia and metastasise is poorly understood. To study blood endothelial cell (BEC) barrier breaching by CRC emboli, an in vitro assay measuring BEC-free areas underneath SW620 cell spheroids, so called "circular chemorepellent induced defects" (CCIDs, appearing in consequence of endothelial retraction), was adapted and supported by Western blotting, EIA-, EROD- and luciferase reporter assays. Inhibition of ALOX12 or NF-κB in SW620 cells or BECs, respectively, caused attenuation of CCIDs...

An integrated approach involving CE experiments, Molecular Dynamics (MD) simulations and two-dimensional NOE spectroscopy (2D-NOESY) experiments was employed to elucidate the intermolecular interactions and the separation mechanisms involved in a solvent-modified MEKC method for the simultaneous determination of diclofenac sodium and its impurities. The CE findings indicated that the addition of n-butanol (nBuOH) to the SDS micellar solution played a primary role for controlling the partitioning into the mixed micelles and the migration of the analytes and that the presence of nBuOH as cosurfactant was compulsory for achieving the complete separation of the compounds...

Ecosystem engineers are profoundly important in many biological communities. A Neotropical taxonomic group considered to have engineering effects is the Formicidae (ants). Leaf-cutter ants (LCAs), in particular, which form extensive colonies of millions of individuals, can be important ecosystem engineers in these environments. While the effects of LCAs on plant community structure and soil chemistry are well-studied, their effects on consumers are poorly understood. Therefore, we examined the indirect effects of the LCA Atta cephalotes L...

Physical cues are major determinants of cellular phenotype and evoke physiological and pathological responses on cell structure and function. Cellular models aim to recapitulate basic functional features of their in vivo counterparts or tissues in order to be of use in in vitro disease modeling or drug screening and testing. Understanding how culture systems affect in vitro development of human pluripotent stem cell (hPSC)-derivatives allows optimization of cellular human models and gives insight in the processes involved in their structural organization and function...

Under physiological conditions, excessive loss of water through the urine is prevented by the release of the antidiuretic hormone arginine-vasopressin (AVP) from the posterior pituitary. In the kidney, AVP elicits a number of cellular responses, which converge on increasing the osmotic reabsorption of water in the collecting duct. One of the key events triggered by the binding of AVP to its type-2 receptor (AVPR2) is the exocytosis of the water channel aquaporin 2 (AQP2) at the apical membrane the principal cells of the collecting duct...
