OBJECTIVE In order to evaluate the relationships between DISH and vertebral osteochondrosis (degenerative disc disease), the radiographs of the spine of 69 DISH patients were compared to those of 68 controls. METHODS Radiographs of 69 patients affected by DISH according to Resnick's criteria and of 68 control subjects affected by diseases other than DISH, were evaluated in order to determine ...

BACKGROUND Although culinary practices have strongly evolved over time, few data are available on contemporary dish choices during meal preparation. We therefore sought to determine individual motives when choosing dishes to be prepared during weekdays and on weekends. METHODS The importance of 27 criteria related to dish choices was assessed in 53,025 participants in the NutriNet-Santé study...

Intercellular interactions are studied using different co-culture systems. Tumor conditioned medium-based systems, filter inserts and direct contact co-culture systems are often used according to research needs. In this article we present a new co-culture technique, using negatively-charged slides (NCS) as the culture surface. The technique was developed on a human-derived endothelial cell line...

DISH is a condition characterized by calcification and/or ossification of soft tissues, mainly entheses, ligaments and joint capsules. Its prevalence increases with age and, therefore, DISH is a relatively common entity in the elderly. The classical site of involvement is the spinal column with right anterolateral soft tissue ossification being the most characteristic feature. However, DISH is ...

Using the formalism of Hamaker et al. (1996), I derive a method for the polarization calibration of observations made with a single radio telescope. This method is particularly appropriate for observations of pulsars, where the sign and magnitude of the circular polarization are useful for understanding the emission processes at work. I apply the method to observations of PSR J1359–6038 made us...

Unattended wireless sensor networks (UWSNs) operating in hostile environments face the risk of compromise. Unable to off-load collected data to a sink or some other trusted external entity, sensors must protect themselves by attempting to mitigate potential compromise and safeguarding their data. In this paper, we focus on techniques that allow unattended sensors to recover from intrusions by s...

Cancer-stromal interaction is a critical process in tumorigenesis. Conventional dish-based co-culture assays simply mix two cell types in the same dish; thus, they are deficient in controlling cell locations and precisely tracking single cell behavior from heterogeneous cell populations. Microfluidic technology can provide a good spatial-temporal control of microenvironments, but the control ha...

Pericytes play an important role in modulating angiogenesis, but the origin of these cells is poorly understood. To evaluate whether the mature vessel wall contains pericyte progenitor cells, nonendothelial mesenchymal cells isolated from the rat aorta were cultured in a serum-free medium optimized for stem cells. This method led to the isolation of anchorage-independent cells that proliferated...

Multilayered cell sheets have been produced from bone marrow-derived mesenchymal stem cells (MSCs) for investigating their adhesion properties onto native porcine heart tissue. Once MSCs reached confluence after a 7-day culture on a temperature-responsive culture dish, a MSCs monolayer spontaneously detached itself from the dish, when the culture temperature was reduced from 37 to 20°C. The bas...

The cerebellum is exquisitely sensitive to deficiencies in the cellular response to specific DNA lesions. Genetic disorders caused by such deficiencies involve relentless, progressive cerebellar atrophy with striking loss of Purkinje and granule neurons. The reason for the extreme sensitivity of these cells to defective response to certain DNA lesions is unclear. This is particularly true for a...
