BACKGROUND: Congenital hyperinsulinism (CHI) is hallmarked by persistent hypoketotic hypoglycemia in infancy. In the majority of all patients, CHI is caused by mutations in the KATP channel genes ABCC8 and KCNJ11, but other genes in the insulin-regulatory pathway have also been described. Repeated episodes of hypoglycemia include an increased risk of seizures and intellectual disability. So far, controlled psychometric studies on cognitive, motor, speech, and social-emotional outcome of CHI patients are missing...

Purpose Delayed intensification (DI) is an integral part of treatment of childhood acute lymphoblastic leukemia (ALL), but it is associated with relevant toxicity. Therefore, standard-risk patients of trial AIEOP-BFM ALL 2000 (Combination Chemotherapy Based on Risk of Relapse in Treating Young Patients With ALL) were investigated with the specific aim to reduce treatment intensity. Patients and Methods Between July 2000 and July 2006, 1,164 patients (1 to 17 years of age) with standard-risk ALL (defined as the absence of high-risk cytogenetics and undetectable minimal residual disease on days 33 and 78) were randomly assigned to either experimental reduced-intensity DI (protocol III; P-III) or standard DI (protocol II; P-II)...

The 'acidic patch' is a highly electronegative cleft on the histone H2A-H2B dimer in the nucleosome. It is a fundamental motif for protein binding and chromatin dynamics, but the cellular impact of targeting this potentially therapeutic site with exogenous molecules remains unclear. Here, we characterize a family of binuclear ruthenium compounds that selectively target the nucleosome acidic patch, generating intra-nucleosomal H2A-H2B cross-links as well as inter-nucleosomal cross-links. In contrast to cisplatin or the progenitor RAPTA-C anticancer drugs, the binuclear agents neither arrest specific cell cycle phases nor elicit DNA damage response, but rather induce an irreversible, anomalous state of condensed chromatin that ultimately results in apoptosis...

BACKGROUND: Acute kidney injury (AKI) is frequently observed in serious infections, following nephrotoxic medication, surgery and trauma. Here we tested whether the detection of two recently identified biomarkers for AKI, Tissue Inhibitor of Metalloproteinase-2 (TIMP-2) and Insulin-Like Growth Factor Binding Protein 7 (IGFBP7), depends on the expression of these proteins in cells of the urinary sediment. METHOD: We collected urine samples of 33 kidney transplant recipients and 14 non-transplanted patients who all had AKI (stages 1-3 according to KDIGO), and measured [IGFBP7]x[TIMP-2] using the NephroCheck® Astute1 40 ™ meter...

Background: Worse chemotherapy response for neurofibromatosis type 1- (NF1-) associated compared to sporadic malignant peripheral nerve sheath tumors (MPNST) has been reported. Methods: We evaluated the objective response (OR) rate of patients with AJCC Stage III/IV chemotherapy-naive NF1 MPNST versus sporadic MPNST after 4 cycles of neoadjuvant chemotherapy, 2 cycles of ifosfamide/doxorubicin, and 2 cycles of ifosfamide/etoposide. A Simon optimal two-stage design was used (target response rate 40%)...

OBJECTIVES: To estimate the cost of functional gastrointestinal disorders (FGIDs) and related signs and symptoms in infants to the third party payer and to parents. STUDY DESIGN: To estimate the cost of illness (COI) of infant FGIDs, a two-stage process was applied: a systematic literature review and a COI calculation. As no pertinent papers were found in the systematic literature review, a 'de novo' analysis was performed. For the latter, the potential costs for the third party payer (the National Health Service (NHS) in England) and for parents/carers for the treatment of FGIDs in infants were calculated, by using publicly available data...

Background: Clinical trials of therapies directed against nodes of the PI3K/AKT/mTOR signaling axis in Glioblastoma (GBM) have had disappointing results. Resistance to mTOR inhibitors limits their efficacy. Methods: To determine mechanisms of resistance to chronic mTOR inhibition, we performed tandem screens on patient-derived GBM cultures. Results: An unbiased phosphoproteomic screen quantified phosphorylation changes associated with chronic exposure to the mTOR inhibitor rapamycin and our analysis implicated a role for GSK3B attenuation in mediating resistance that was confirmed by functional studies...

Nonsyndromic cleft lip with or without cleft palate (nsCL/P) is one of the most common congenital malformation worldwide, and its etiology involves both genetic and environmental factors. Recent genome-wide and targeted genetic studies of nsCL/P have identified numerous genetic risk loci, under the hypothesis of a multiplicative mode of inheritance. The present study investigated whether novel nsCL/P risk loci could be identified by analyzing dominant/recessive genetic effects in single nucleotide polymorphism (SNP) data from genome-wide association studies...

Lipidic cubic phase systems (LCPs) are excellent carriers for immobilized enzymes due to their biocompatibility and well-defined nanoporous structure. Lipidic cubic phases act as a convenient matrix to incorporate enzymes and hold them in the vicinity of electrode surfaces in their fully active forms. Corynascus thermophilus cellobiose dehydrogenase (CtCDH) was trapped in a monoolein cubic phase, which increased not only its stability, but also its catalytic performance with both enhanced mediated and direct electron transfer with electrodes...

OBJECTIVE: Treatment monitoring and outcome evaluation in pediatric hydrocephalus require gapless documentation regarding surgical and clinical follow-up data beginning from day 1 of treatment in order to apply high quality of care. Endoscopic procedures, shunt insertion and revision surgeries, and individual modifications of valve hardware or pressure settings during follow-up as well as established outcome measurements are highly relevant for complete illustration of the patient's hydrocephalus histories...

Treatment of high-risk patients is a major challenge in multiple myeloma. This is especially true for patients assigned to the gene-expression-profiling defined proliferation subgroup. Although recent efforts have identified some key players of proliferative myeloma, genetic interactions and players that can be targeted with clinically effective drugs have to be identified to overcome the poor prognosis of these patients. We therefore examined maternal embryonic leucine zipper kinase (MELK) for its implications in hyper-proliferative myeloma and analysed the activity of the MELK inhibitor OTSSP167 in vitro and in vivo...

Early administration of reperfusion therapy in acute ST-elevation myocardial infarctions (STEMI) is crucial to reduce mortality. Although female sex and old age are key factors contributing to an inadequate long prehospital delay time, little is known whether women ≥65 years are a particular risk population. Hence, we studied the interaction of sex and age (<65 years or ≥65 years) and the contribution of chest pain to delay time during STEMI. Bedside interview data were collected in 619 STEMI patients from the Munich Examination of Delay in Patients Experiencing Acute Myocardial Infarction (MEDEA) study...

In tissue engineering applications, vascularization can be accomplished by co-implantation of tissue forming cells and endothelial cells (ECs), whereby the latter are able to form functional blood vessels. The use of three-dimensional (3D) bioprinting technologies has the potential to improve the classical tissue engineering approach because these will allow the generation of scaffolds with high spatial control of endothelial cell allocation. This study focuses on a side by side comparisons of popular commercially available bioprinting hydrogels (matrigel, fibrin, collagen, gelatin, agarose, Pluronic F-127, alginate and alginate/gelatin) in the context of their physicochemical parameters, their swelling/degradation characteristics, their biological effects on vasculogenesis-related EC parameters and their printability...
