Testis-derived Sertoli cells have a trophic effect on dopamine neurons and alleviate hemiparkinsonism in rats

Neural tissue transplantation has become an alternative treatment for Parkinson's disease (PD) and other neurodegenerative disorders. The clinical use of neural grafts as a source of dopamine for Parkinson's disease patients, although beneficial, is associated with logistical and ethical issues. Thus, alternative graft sources have been explored including polymer-encapsulated cells and nonneural c

Post-thaw viability and functionality of cryopreserved rat fetal brain cells cocultured with Sertoli cells

Testis-derived Sertoli cells have been used to create an immune "privileged" site outside of the testis to facilitate cell transplantation protocols for diabetes and neurodegenerative diseases. In addition to secreting immunoprotective factors, Sertoli cells also secrete growth and trophic factors that appear to enhance the posttransplantation viability of isolated cells and, likewise, the posttha

Specific effects of platelet derived growth factor (PDGF) on fetal rat and human dopaminergic neurons in vitro

The neurotrophic effects of the BB isoform of platelet-derived growth factor (PDGF) on rat and human fetal mesencephalic dopaminergic neurons have been characterized in vitro. A dose-response analysis demonstrated maximal responses at 30 ng/ml of PDGF-BB. This concentration resulted in a marked increase in the survival and neurite outgrowth from rat and human tyrosine hydroxylase-(TH) positive, pr

BDNF makes cultured dentate granule cells more resistant to hypoglycaemic damage

The aim of this study was to explore whether brain-derived neurotrophic factor (BDNF) can improve neuronal survival in cell cultures of rat dentate gyrus subjected to a hypoglycaemic insult. Glucose deprivation for 15 h caused severe neuronal loss (about 70%). BDNF added either 24 h before or 4 h after onset of hypoglycaemia completely protected granule cells against this insult-induced damage. Ne

Stem cells in cell transplantation

This commentary documents the increased number of stem cell-related research reports recently published in the cell transplantation field in the journal Cell Transplantation. The journal covers a wide range of issues in cell-based therapy and regenerative medicine and is attracting clinical and preclinical articles from around the world. It thereby complements and extends the basic coverage of ste

Pairing Wikipedia Articles Across Languages

Wikipedia has become a reference knowledge source for scores of NLP applications. One of its invaluable features lies in its multilingual nature, where articles on a same entity or concept can have from one to more than 200 different versions. The interlinking of language versions in Wikipedia has undergone a major renewal with the advent of Wikidata, a unified scheme to identify entities and their

Insurance in European VAT : Current and Preferred Treatment in the Light of the New Zealand and Australian GST System

The book provides a thorough legal analysis of the treatment of insurance in the harmonized system of European VAT as compared to the treatment of insurance in the New Zealand and Australian Goods and Services Tax (GST) systems. Insurance constitutes a significant part of the financial services sector, and it is one of the foundations of a modern society and economy. In the design of tax laws, how

Synthesis of 14-oxa-1,4,8,11-tetraazabicyclo[9,5,3]nonadecane (L1) and a Spectroscopic and Structural Study of [Ni(L1)(ClO4)](ClO4) and of the Macrobicyclic Precursor Diamide Complex, [Ni(HL2)](ClO4); Chloride Substitution Kinetics of the Corresponding [Ni(III)(L1)]3+ Species

The pentadentate ligand 14-oxa-1,4,8,11-tetraazabicyclo[9.5.3]nonadecane (L1) has been synthesized by the high dilution cyclization of 1-oxa-4,8-diazacyclododecane ([10]aneN2O) (1) with 1,3-bis(α-chloroacetamido)propane (2) and subsequent reduction of the diamide intermediate. The structure [Ni(L1)(ClO4)](ClO4) (P21/c (no. 14), a = 8.608(3), b = 16.618(3), c = 14.924(4) Å, β = 91.53(3)° converged

Compliance with guidelines for postoperative pain management in infants and children

Background: Postoperative pain is still often being inadequately assessed and/or recorded in infants and young children despite evidence-based guidelines. Objectives: This prospective, observational study in a paediatric postoperative ward at a Swedish university hospital was designed to evaluate interventional effects on pain management by briefly reminding nursing staff of corresponding local gu

High-Density Lipoprotein–Associated Apolipoprotein M Limits Endothelial Inflammation by Delivering Sphingosine-1-Phosphate to the Sphingosine-1-Phosphate Receptor 1

OBJECTIVE—: Plasma high-density lipoproteins (HDL) are potent antiatherogenic and anti-inflammatory particles. However, HDL particles are highly heterogenic in composition, and different HDL-mediated functions can be ascribed to different subclasses of HDL. Only a small HDL population contains apolipoprotein M (ApoM), which is the main plasma carrier of the bioactive lipid mediator sphingosine-1-p

A novel process of viral vector barcoding and library preparation enables high-diversity library generation and recombination-free paired-end sequencing

Detailed characterization and mapping of oligonucleotide function in vivo is generally a very time consuming effort that only allows for hypothesis driven subsampling of the full sequence to be analysed. Recent advances in deep sequencing together with highly efficient parallel oligonucleotide synthesis and cloning techniques have, however, opened up for entirely new ways to map genetic function i

Laparoscopic distal pancreatectomy in elderly patients : is it safe?

Background: Laparoscopic distal pancreatectomy (LDP) appears to be safe and effective as open distal pancreatectomy (ODP) for benign or borderline malignant lesion. However, studies comparing LDP with ODP in elderly patients are limited. The purpose of this study is to compare the clinical outcomes of these two several approaches in elderly patients. Methods: A retrospective analysis was carried o

Mineral Type Structures Soil Microbial Communities

Soil microorganisms living in close contact with minerals play key roles in the biogeochemical cycling of elements, soil formation, and plant nutrition. Yet, the composition of microbial communities inhabiting the mineralosphere (i.e., the soil surrounding minerals) is poorly understood. Here, we explored the composition of soil microbial communities associated with different types of minerals in
