Frank Fideler, Christian Grasshoff
The perioperative care of children is challenging for health care providers. Since anesthetists cannot affect the nature of the disease and have hardly an impact on the decision for surgery we summarized in this review individual and institutional factors for improving perioperative outcome by anesthetists. Individual factors include the level of education and the professional experience of the anesthetist as well as an anesthetic management that is focused on the maintenance of an adequate cerebral perfusion...

Polyamines (PAs) can improve drought stress tolerance in plants; however, very limited information is available on the mechanism of action of exogenous application by different methods under drought stress in wheat. The present study investigates the mechanism through which seed priming and foliar spraying with PAs protect wheat plants from drought stress. 10 days old wheat seedlings were exposed to drought stress by withholding water alone or with 100 μM PAs solutions (putrescine, Put; spermine, Spm; and mixture of Put and Spm for 10 h seed-priming or three foliar sprays during withholding water...

Parathyroid hormone receptors are present in bone cells and play a crucial role in the maintenance of skeletal integrity, bone homeostasis and regulation of calcium and phosphate metabolism. Although the function of these receptors has long being recognized in the cells of the osteoblastic lineage regulating directly osteoblast differentiation and function and indirectly osteoclastogenesis, recent findings demonstrate their functional presence in osteocytes participating in the co-ordination of bone remodelling...

Purpose Lenalidomide maintenance therapy after autologous stem-cell transplantation (ASCT) demonstrated prolonged progression-free survival (PFS) versus placebo or observation in several randomized controlled trials (RCTs) of patients with newly diagnosed multiple myeloma (NDMM). All studies had PFS as the primary end point, and none were powered for overall survival (OS) as a primary end point. Thus, a meta-analysis was conducted to better understand the impact of lenalidomide maintenance in this setting. Patients and Methods The meta-analysis was conducted using primary-source patient-level data and documentation from three RCTs (Cancer and Leukemia Group B 100104, Gruppo Italiano Malattie Ematologiche dell'Adulto RV-MM-PI-209, and Intergroupe Francophone du Myélome 2005-02) that met the following prespecified inclusion criteria: an RCT in patients with NDMM receiving ASCT followed by lenalidomide maintenance versus placebo or observation with patient-level data available and achieved database lock for primary efficacy analysis...

BACKGROUND: Alcohol and drug dependencies are associated with different social stigmas, and some studies suggest they might exhibit different clinical presentations. Further, the treatments for each vary considerably. Alcohol versus drug use problems were compared in terms of attachment patterns and related clinical treatment issues in two interlocking studies using converging logic and designs. METHODS: In Study 1, alcohol versus drug dependence was defined in terms of a known groups design...

The pseudanthial inflorescences of the sunflower family, Asteraceae, mimic a solitary flower but are composed of multiple flowers. Our studies in Gerbera hybrida indicate functional diversification for SEPALLATA (SEP)-like MADS box genes that often function redundantly in other core eudicots. We conducted phylogenetic and expression analysis for eight SEP-like GERBERA REGULATOR OF CAPITULUM DEVELOPMENT (GRCD) genes, including previously unstudied gene family members. Transgenic gerbera plants were used to infer gene functions...

Elderly patients represent a growing population among people suffering from ESRD. So far only limited data on actual survival benefits of elderly adults initiating dialysis have been published. Besides the high burden of preexisting comorbidities, dialysis treatment itself may be associated with a further deterioration in functional status in this population. We retrospectively analyzed the Austrian Dialysis and Transplant Registry and identified 8,622 patients who started maintenance hemodialysis after the age of 65 years between 2002 and 2009...

All cells are subject to structural damage that must be addressed for continued growth. A wide range of damage affects the genome, meaning multiple pathways have evolved to repair or bypass the resulting DNA lesions. Though many repair pathways are conserved, their presence or function can reflect the life style of individual organisms. To identify genome maintenance pathways in a divergent eukaryote and important parasite, Trypanosoma brucei, we performed RNAi screens to identify genes important for survival following exposure to the alkylating agent methyl methanesulphonate...

Axons contain a smooth tubular endoplasmic reticulum (ER) network that is thought to be continuous with ER throughout the neuron; the mechanisms that form this axonal network are unknown. Mutations affecting reticulon or REEP proteins, with intramembrane hairpin domains that model ER membranes, cause an axon degenerative disease, hereditary spastic paraplegia (HSP). We show that Drosophila axons have a dynamic axonal ER network, which these proteins help to model. Loss of HSP hairpin proteins causes ER sheet expansion, partial loss of ER from distal motor axons, and occasional discontinuities in axonal ER...

BACKGROUND: Compared with neurologic determination of death (NDD) donor organs, donation after cardiac death (DCD) donor organs have traditionally been considered of inferior quality owing to warm ischemia experienced during procurement. We present, to our knowledge, the first analysis of simultaneous pancreas and kidney (SPK) transplants using DCD donor organs in Canada. METHODS: We carried out a retrospective cohort study of SPK transplants from 13 DCD and 68 NDD donors performed between October 2008 and July 2016...

Limited data are available regarding the effects of whey protein on the nutritional status of the peritoneal dialysis population. This study evaluated the effects of whey protein supplementation for 12 weeks on the nutritional status in hypoalbuminemic peritoneal dialysis patients. Thirty-six stable adult patients on maintenance peritoneal dialysis with serum albumin levels <3.5 g/dL were enrolled in the study and were divided into two groups similar in their serum albumin and normalized protein equivalent of total nitrogen appearance (nPNA)...

Plant class-II glutaredoxins (GRXs) are oxidoreductases carrying a CGFS active site signature and are able to bind iron-sulfur clusters in vitro. In order to explore the physiological functions of the two plastidial class-II isoforms, GRXS14 and GRXS16, we generated knockdown and overexpression Arabidopsis thaliana lines and characterized their phenotypes using physiological and biochemical approaches. Plants deficient in one GRX did not display any growth defect, whereas the growth of plants lacking both was slowed...

REVIEW
Luana Schito, Gregg L Semenza
Intratumoral hypoxia (reduced O2 availability) is a common finding in human cancer and leads to increased activity of hypoxia-inducible factors (HIFs), which regulate the expression of genes that contribute to angiogenesis, metabolic reprogramming, extracellular matrix remodeling, epithelial-mesenchymal transition, motility, invasion, metastasis, cancer stem cell maintenance, immune evasion, and resistance to chemotherapy and radiation therapy. Conventional anticancer therapies target well-oxygenated and proliferating cancer cells, whereas there are no approved therapies that target hypoxic cancer cells, despite growing clinical and experimental evidence indicating that intratumoral hypoxia is a critical microenvironmental factor driving cancer progression...

Maintenance of genomic integrity is critical for adaptive survival in the face of endogenous and exogenous environmental stress. The loss of stability and fidelity in the genome caused by cancer and cancer treatment provides therapeutic opportunities to leverage the critical balance between DNA injury and repair. Blocking repair and pushing damaged DNA through the cell cycle using therapeutic inhibitors exemplify the 'pushmi-pullyu' effect of disrupted DNA repair. DNA repair inhibitors (DNARi) can be separated into five biofunctional categories: sensors, mediators, transducers, effectors, and collaborators that recognize DNA damage, propagate injury DNA messages, regulate cell cycle checkpoints, and alter the microenvironment...

Weight-loss surgery requires lifelong lifestyle modifications for the maintenance of weight loss and health effects, and can affect both the individual and family. Earlier research indicates that the quality of social relationships has positive and negative influences on wellbeing and health. There is little research on family-life after a member has undergone gastric bypass (GBP) against obesity. Thus, this study aimed to develop a classic grounded theory about families with a member treated with GBP against obesity...

Glioblastoma is the most common and highly malignant primary brain tumor, and patients affected with this disease exhibit a uniformly dismal prognosis. Glioma stem-like cells (GSCs) are a subset of cells within the bulk tumor that possess self-renewal and multi-lineage differentiation properties similar to somatic stem cells. These cells also are at the apex of the cellular hierarchy and cause tumor initiation and expansion after chemo-radiation. These traits make them an attractive target for therapeutic development...

The emergence of whole-genome assays has initiated numerous genome-wide studies of transcription factor localizations at genomic regulatory elements (enhancers, promoters, silencers, and insulators), as well as facilitated the uncovering of some of the key principles of chromosomal organization. However, the proteins involved in the formation and maintenance of the chromosomal architecture and the organization of regulatory domains remain insufficiently studied. This review attempts to collate the available data on the abundant but still poorly understood family of proteins with clusters of the C2H2 zinc finger domains...
