This study determined if the hippocampal theta rhythm showed phase relationships or changes in amplitude and frequency with the onset of stimuli and locomotion in a task in which auditory cues initiated and suppressed approach locomotion. Rats with electrodes in the dorsal hippocampus lapped at a milk dipper and were presented a tone which predicted the delivery of a food pellet. In some trials...

Six cynomolgus monkeys (Macaca fascicularis) were trained to associate visual stimuli with the delivery of various amounts of food reward. The animals had to choose correctly between pairs of stimuli drawn from a population of 16. Four of these stimuli were associated with 0 reward pellets, four with 1 pellet, four with 2 pellets and four with 4 pellets. Mediodorsal thalamic lesions including t...

There is a growing concern that the velocity of the DT-ice pellets being proposed to fuel ITER will not have the velocity to effectively penetrate through the pedestal of the plasma edge, because with velocities of only 300 m/s, high field side launched pellets will only penetrate to € r /a = 0.90, which may not be adequate for fueling. The likelihood of increasing the pellet velocity is proble...

Received: 25/Sep/2006, Accepted: 22/Nov/2006 Introduction: The aim of this study was to differentiate human mesenchymal stem cells (hMSCs) into cartilage in a micromass culture system and study of their structure by light and electron microscopy. Material and Methods: Human bone marrow cells obtained from volunteer patients were plated in 75-cm flasks and their MSCs were expanded through severa...

This article is an adaptation of an abstract/poster presentaton made at the 13th International Congress on Steroidal Hormones and Hormones and Cancer, Quebec City, Canada (September 2008), concerning the topic of breast feeding as a contraindication to testosterone therapy. The purpose of the presentation and this article is to provide a summary of the findings of a study that was conducted to ...

N-1-Naphthylphthalamic acid (NPA) binding activity is released into the supernatant when plasma membranes are subjected to high-salt treatment, indicating that this activity is peripherally associated with the membrane. Extraction of plasma membrane vesicles with Triton X-100 resulted in retention of NPA binding activity in the detergent-insoluble cytoskeletal pellet. Treatment of this pellet w...

High-density cell culture is widely used for the analysis of cartilage development of human mesenchymal stem cells (HMSCs) in vitro. Several cell culture systems, as micromass, pellet culture and alginate culture, are applied by groups in the field to induce chondrogenic differentiation of HMSCs. A draw back of all model systems is the high amount of cells necessary for the experiments. Further...

The purpose of this study was to identify culture conditions for maintenance of isolated mouse type II cells with intact surfactant protein (SP) and phospholipid production. Type II cells were isolated from 6-wk-old mice and cultured on Matrigel matrix-rat tail collagen (70:30 vol/vol) in bronchial epithelial cell growth medium minus hydrocortisone plus 5% charcoal-stripped FBS and 10 ng/ml ker...
