BACKGROUND: Tight and personalised control of inflammatory bowel disease in a traditional setting is challenging because of the disease complexity, high pressure on outpatient clinics, and rising incidence. We compared the effects of self-management with a telemedicine system, which was developed for all subtypes of inflammatory bowel disease, on health-care utilisation and patient-reported quality of care versus standard care. METHODS: We did this pragmatic, randomised trial in two academic and two non-academic hospitals in the Netherlands...

Ripening of fleshy fruits is controlled by a series of intricate signaling processes. Here, we report a FERONIA/FER-like receptor kinase, FaMRLK47, that regulates both strawberry (Fragaria × ananassa) fruit ripening and quality formation. Overexpression and RNAi-mediated downregulation of FaMRLK47 delayed and accelerated fruit ripening, respectively. We showed that FaMRLK47 physically interacts with FaABI1, a negative regulator of abscisic acid (ABA) signaling, and demonstrated that FaMRLK47 regulates fruit ripening by modulating ABA signaling, a major pathway governing strawberry fruit ripening...

Eugene Stephane Mananga
In this work, we investigated the orders to which the Floquet-Magnus expansion (FME) and Fer expansion (FE) are equivalent or different for the three-level system. Specifically, we performed the third-order calculations of both approaches based on elegant integrations formalism. We present an important close relationship between the Floquet-Magnus and Fer expansions. As the propagator from the FME takes the form of the evolution operator which removes the constraint of a stroboscopic observation, we appreciated the effects of time-evolution under Hamiltonians with different orders separately...

While behavioural difficulties in facial emotion recognition (FER) have been observed in individuals with Autism Spectrum Disorder (ASD), behavioural studies alone are not suited to elucidate the specific nature of FER challenges in ASD. Eye tracking (ET) and electroencephalography (EEG) provide insights in to the attentional and neurological correlates of performance, and may therefore provide insight in to the mechanisms underpinning FER in ASD. Given that these processes develop over the course of the developmental trajectory, there is a need to synthesise findings in regard to the developmental stages to determine how the maturation of these systems may impact FER in ASD...

Bruno Azambre, Mouheb Chebbi
In this study, up to 13 different silver zeolites sorbents were prepared by repeated ion exchange from their parent structures (FAU X and Y, MOR, *BEA, MFI, FER), characterized, and evaluated for their ability to capture methyl iodide in the context of a nuclear severe accident. A novel methodology was implemented to establish structure-activity relationships between sorbent properties and iodine trapping stability. After saturation of the zeolite bed with CH3I during a dynamic breakthrough experiment at 100 °C, a two-step quantitative desorption method was elaborated with the aim to quantify separately the CH3I fractions trapped by physisorption, chemisorption, or reacted as AgI precipitates...

The symptoms of autism spectrum disorder (ASD) have been hypothesized to be caused by changes in brain connectivity. From the clinical perspective, the "disconnectivity" hypothesis has been used to explain characteristic impairments in "socio-emotional" function. Therefore, in this study we compared the facial emotional recognition (FER) feature and the integrity of social-emotional-related white-matter tracts between children and adolescents with high-functioning ASD (HFA) and their typically developing (TD) counterparts...

In case of erythropoiesis, body iron needs to increase to enable the production of new red blood cells. In the 1950s, the observation of an increased digestive iron absorption in the case of phlebotomies had led to propose the existence of an "erythroid factor", which regulate the availability of iron for erythropoiesis in this situation. The factor regulating iron stores has been identified in 2000 to be hepcidin. Recently, in 2014, a new factor was discovered, which regulates iron metabolism, independently of iron stores and responds to the increased requirements for iron after stimulation of erythropoiesis by erythropoietin...

Human mitoNEET is a homodimeric protein anchored to the outer mitochondrial membrane and has a C-terminal [2Fe-2S] binding domain located in the cytosol. Recently, human mitoNEET has been shown to be implicated in Fe/S cluster repair of cytosolic iron regulatory protein 1 (IRP1), a key regulator of cellular iron homeostasis in mammalian cells. The Fe/S cluster repair function of mitoNEET is based on an Fe/S redox switch mechanism: under normal cellular conditions, reduced [2Fe-2S](+)-mitoNEET is present and is inactive as an Fe/S cluster transfer protein; under conditions of oxidative cellular stress, the clusters of mitoNEET become oxidized, and the formed [2Fe-2S](2+)-mitoNEET species reacts promptly to initiate Fe/S cluster transfer to IRP1, recycling the cytosolic apo-IRP1 into holo-aconitase...

OBJECTIVE: Chordomas and chondrosarcomas are tumors that can occur in the skull base. Currently, 45% of chordomas and 56% of chondrosarcomas recur within five years of surgery. The role of adjuvant therapy is highly debated. No pharmacotherapies have been approved by the FDA for chordomas or chondrosarcomas. The high propensity for recurrence and lack of definitive adjuvant therapy necessitates additional basic science research to identify molecular anomalies associated with recurrent disease...

Dermatomyositis (DM) is an autoimmune disorder associated with a dysregulation of immune homeostasis of both the innate and adaptive immune system. Earlier data suggested that these two arms of the immune system interconnect in DM. In the current study, we analysed the association of autoantigen expression [adaptive system components: Mi2, transcriptional intermediary factor (TIF)1γ, small ubiquitin-like modifier 1 activating enzyme subunit (SAE)1, melanoma differentiation-associated protein (MDA)5] with markers of cellular stress (innate system components: MxA, p53) in skin and muscle (immunohistology and gene expression data, respectively)...

The present study was focused on the growth, body composition, metabolic abilities and innate immune responses in juvenile black carp Mylopharyngodon piceus fed with six levels of dietary leucine (7.3, 12.4, 16.2, 21.9, 28.3 and 34.5 g kg(-1)) for 9 weeks. Results showed that the highest weight gain (WG) and the lowest feed conversion ratio (FCR) was obtained at 23.5 and 23.9 g kg(-1) dietary leucine using second-order polynomial model, respectively. Adequate dietary leucine content (21.9 and 28.3 g kg(-1)) could significantly up-regulate the expression levels of neuropeptide Y (NPY) and ghrelin (GRL) in the brain of black carp juveniles...

Ferroptosis has recently been identified as a mode of programmed cell death. However, little is yet known about the signaling mechanisms. Here, we report that lipoxygenases (LOX) contribute to the regulation of RSL3-induced ferroptosis in acute lymphoblastic leukemia (ALL) cells. We show that the glutathione (GSH) peroxidase 4 (GPX4) inhibitor RSL3 triggers lipid peroxidation, production of reactive oxygen species (ROS) and cell death in ALL cells. All these events are impeded in the presence of Ferrostatin-1 (Fer-1), a small-molecule inhibitor of lipid peroxidation...

BACKGROUND AND AIM: Differential diagnosis between Cushing's Disease (CD) and Ectopic ACTH Syndrome (EAS) may be a pitfall for endocrinologists. The increasing use in clinical practice of chromatography and mass spectrometry improves the measurement of urinary free cortisol (UFF) and cortisone (UFE). We have recently observed that cortisol to cortisone ratio (FEr) was higher in a small series of EAS; in this paper we collected a larger number of ACTH-dependent CS to study the role of FEr to characterize the source of corticotropin secretion...

Cancer stem cells (CSCs) are a subpopulation of cancer cells and have been known to create cancer reoccurrence during cancer therapy due to their stem cell-like characteristics. However, exact target to control the CSC has not been fully established. Here, we enriched CD44(High) population of MDA-MB-231 cells by CD44 antibody as a CSC marker. By Phospho Antibody Array, CD44(High) population of MDA-MB-231 cells reveals Feline sarcoma-related tyrosine kinase (FER) protein was highly activated. When FER siRNA and low molecular weight protamine (LMWP) as cell penetrating peptides are applied to this population, cancer migration and colony forming ability are inhibited...

STUDY QUESTION: Does a short abstinence period of only 2 h yield spermatozoa with better motility characteristics than samples collected after 4-7 days? SUMMARY ANSWER: Despite lower semen volume, sperm concentration, total sperm counts and total motile counts, higher percentages of motile spermatozoa with higher velocity and progressiveness were detected in samples obtained after 2 h. WHAT IS KNOWN ALREADY: Most studies that have assessed the effect of abstinence periods on sperm motility parameters in men with a sperm concentration below 15 million/ml have detected a higher percentage of motile spermatozoa in samples obtained after short abstinence periods...

Although overexpression of genes encoding detoxification enzymes is a well-known mechanism of pesticide resistance of mites, the regulators involved in this process are still illiterate. Previous studies in our laboratory demonstrated that the overexpression of six P450 genes contributes to fenpropathrin resistance in T. cinnabarinus. In this study, six transcription factor genes that likely regulate the expression of P450 genes were identified and characterized. Quantitative PCR (qPCR) analysis showed that three transcription factor genes were highly expressed in a fenpropathrin-resistant (FeR) strain of T...
