Signs of Degeneration in 12-22-Year Old Grafts of Mesencephalic Dopamine Neurons in Patients with Parkinson's Disease

We demonstrate that grafted human fetal mesencephalic neurons can survive and extend axons for 22 years in the brain of a patient with Parkinson's disease (PD). In this patient, the overall survival and fiber outgrowth of the grafts were, however, relatively poor, which is consistent with the lack of significant clinical graft-induced benefit. We have compared the morphology of neurons in the 22-y

Evaluation of commercial microbial hydrocolloids concerning their effects on plasma lipids and caecal formation of SCFA in mice

Exopolysaccharides (EPS) are excreted by microorganisms into the surrounding environment and have been shown to have various physiological effects and are commonly used as food additives due to their rheological properties. Four commercially available microbial EPS with different polymeric structures and composition were tested in LDL receptor knock-out mice to investigate their effect on blood ch

Pancreatic β-cell dysfunction, expression of iNOS and the effect of phosphodiesterase inhibitors in human pancreatic islets of type 2 diabetes.

AIMS: Induction of iNOS in pancreatic islets leads to exaggerated NO production associated with dysfunctional β-cells. We examined insulin secretion, iNOS expression and its relation to the cAMP system in islets from human type 2 diabetes. METHODS: Insulin, glucagon and cAMP were analyzed by RIA; iNOS or PDE expression by qPCR, Western blot and confocal microscopy; cell viability by MTS. RESU

Packaging in developing countries – Identifying supply chain needs

Purpose: To explore packaging in developing countries by means of identifying and describing supply chain needs regarding packaging. Design/methodology/approach: The research approach is qualitative and includes an embedded single case study of ambient milk supply chains in developing countries. Data collection is based on the review of internal company documents, semi-structured interviews with i

Genome-wide association study and mouse expression data identify a highly conserved 32kb intergenic region between WNT3 and WNT9b as possible susceptibility locus for isolated classic exstrophy of the bladder.

Bladder Exstrophy-Epispadias Complex (BEEC), the severe end of the uro-rectal malformation spectrum, has a profound impact on continence as well as sexual and renal functions. It is widely accepted that for the majority of cases the genetic basis appears to be multifactorial. Here, we report the first study which utilizes genome-wide association methods to analyze a cohort comprising patients pres

Coomassie Staining as Loading Control in Western Blot Analysis

In Western blotting, immunodetection of housekeeping proteins is routinely performed to detect differences in electrophoresis loading. The present work describes a much faster and simpler protein staining method, which is compatible with ordinary blocking conditions. In addition, the method can be used after immunodetection with superior linearity compared to ordinary staining methods. After immun

Spate irrigation of barley through floodwater harvesting in the Gareh-Bygone Plain, Iran

Utilizing passive floodwater for spate irrigation in arid areas is an opportunity to use marginal water for production of crops. These techniques have only partially been studied in an extensive way. This paper describes a floodwater harvesting and spreading system for spate irrigation and field experiments for cultivation of barley. The field experiments were carried out during a three-year perio

Growing Big Science in a Small Country: MAX-Iab and the Swedish Research Policy System

MAX-lab is a Swedish national synchrotron radiation facility, first established as a small-scale university project in the late 1970s and then gradually developed into a national and international user facility. This article presents a historical study of MAX- lab that illustrates the decentralized character of the Swedish science policy system and especially its lack of aggregation mechanisms for

Hand function and performance of daily activities in systemic lupus erythematosus: a clinical study.

This clinical study was performed to investigate hand problems in individuals with systemic lupus erythematosus (SLE) in comparison with healthy controls, and to explore problems in the performance of daily activities related to these hand problems, in order to objectify findings from a previous mail survey. We also investigated whether a simple hand test could detect hand problems in SLE. All ind

Sustained Attention and Motivation in Zen Meditators and Non-meditators

This study investigated the ability of Zen meditators and non-meditators to sustain attention during an ongoing task. We hypothesized that meditators (n = 15) would sustain attention more efficiently than non-meditators (n = 19) by responding faster to task stimuli, making fewer commission errors, and reporting fewer interfering thoughts in the sustained attention to response task (SART). Their mo

Disturbance of posture in children with very low lead exposure, and modification by VDR FokI genotype.

Introduction and objective. Lead has a negative effect on the central nervous system (CNS), inter alia indicated by disturbance of posture. However, knowledge of the CNS effects at low exposure is insufficient. Individuals differ in vulnerability, possibly because of genetic predisposition. Polymorphisms in the δ-aminolevulinic acid dehydratase (ALAD) and vitamin D receptor (VDR) genes may modify

High serum cholesterol predicts rheumatoid arthritis in women, but not in men: a prospective study.

Environmental exposures, including smoking, hormone-related factors, and metabolic factors, have been implicated in the etiology of rheumatoid arthritis (RA). A previous study has indicated that blood lipid levels may influence the development of RA. The objective of this study was to investigate the impact of serum total cholesterol and triglycerides on the risk of RA in a prospective study.

Revisiting the taxonomy of Phanerochaete (Polyporales, Basidiomycota) using a four gene dataset and extensive ITS sampling.

We amplified RPB1, RPB2, and the ITS and LSU ribosomal genes from species mostly in the phlebioid clade, focusing heavily in phanerochaetoid taxa. We performed Maximum Likelihood and Bayesian analyses for different combinations of datasets. Our results provide a strongly supported phylogenetic picture of the phlebioid clade, representing 89 species in the four genes analyses, of which 49 represent

Anthropometric Measures, Body Mass Index, and Pancreatic Cancer A Pooled Analysis From the Pancreatic Cancer Cohort Consortium (PanScan)

Background: Obesity has been proposed as a risk factor for pancreatic cancer. Methods: Pooled data were analyzed from the National Cancer Institute Pancreatic Cancer Cohort Consortium (PanScan) to study the association, between prediagnostic anthropometric measures and risk of pancreatic cancer. PanScan applied a nested case-control study design and included 2170 cases and 2209 control subjects. O

Minimizing risk of hypomethylating agent failure in patients with higher-risk MDS and practical management recommendations.

In Europe, azacitidine is the only hypomethylating agent approved for the treatment of patients with int-2-/high-risk myelodysplastic syndromes, offering significantly improved survival compared with conventional care. However, not all patients treated with azacitidine respond to treatment, and the vast majority of responders subsequently relapse. Currently, no standard care regimens have been est

An empirical index of insulin sensitivity from short IVGTT: validation against the minimal model and glucose clamp indices in patients with different clinical characteristics

Aims/hypothesis Minimal model analysis for insulin sensitivity has been validated against the glucose clamp and is an accepted method for estimating insulin sensitivity from IVGTT. However minimal model analysis requires a 3 h test and relevant expertise to run the mathematical model. The aim of this study was to suggest a simple predictor of minimal model analysis index using only 1 h IVGTT. Meth

High Expression of Midkine in the Airways of Patients with Cystic Fibrosis.

Mutations in the CFTR gene result in impaired host defense during cystic fibrosis (CF), where Pseudomonas aeruginosa becomes a key pathogen. We investigated the expression pattern of the antibacterial growth factor midkine in CF and possible interference with its activity by the altered airway microenvironment. High midkine expression was found in CF lung tissue compared with controls, involving e

The BETHY/JSBACH Carbon Cycle Data Assimilation System: experiences and challenges

We present the concept of the Carbon Cycle Data Assimilation System and describe its evolution over the last two decades from an assimilation system around a simple diagnostic model of the terrestrial biosphere to a system for the calibration and initialization of the land component of a comprehensive Earth system model. We critically review the capability of this modeling framework to integrate m
