Dr. Benacerraf describes his experience in training immunologists for a period of over 30 years. He then analyzes the circumstances in which selected discoveries were made in his laboratory and the events and reasoning that led to these findings. The following topics are discussed: The phagocytic activity of the reticulo-endothelial system. The pathogenesis of immune complex diseases. The impac...

conclusions flushing dental unit waterlines are an effective measure in reducing the number of bacterial contaminants. results bacterial contamination was found in all 24 units at the beginning of daily activity with a mean colony count of 17850. the number of colonies decreased to 3250 following 30 seconds of flushing in 16 units and later to 1837 after flushing for two minutes in 13 units. in...

In this work, fresh soybean meal was used as the substrate for both batch and continuous experiments in a rotational drum fermentation (RDF) system to characterize the acidogenic process of solid organic waste degradation at high unionized volatile acid (U-VA) level and evaluate the effect of water flushing on the acidogenic performance. The experiments were conducted under mesophilic condition...

These days, huge amounts of data are created by not only humans but also the Internet of Things (IoT). As databases increase in size, their buffer pool is becoming more crucial to the overall performance. Buffer flushing, i.e., writing dirty pages, is a key factor in buffer pool management. Tuning the buffer-flushing activity in a real system is often difficult because it depends on the workloa...

During a control infusion noradrenaline and alcohol each provoked carcinoid flushing in four of five patients and pentagastrin in two of five patients. When tetradecapeptide somatostatin was infused on another day no patient flushed at any time, even when 16 microgram of either noradrenaline or pentagastrin were administered. Carcinoid flushing was not associated with release of gastrin or any ...

flushing is a condition with episodic attacks of redness of the skin with a sensation of warmth or burning, this disease causes emotional and functional problems in patients. there is various treatments for this condition; one of them is the use of botulinum toxin-a (bta). in this prospective pilot study we studied the effect of botulinum toxin-a (bta) effect on dlqi of patients with facial flu...

How to increase the efficiency of chemical flushing and decrease the remediation expenses of contaminated soils are two key scientific and technological issues to be solved. Joint chemical flushing was tested and compared with the water-flushing. The joint acid-flushing could effectively remove petroleum hydrocarbons in contaminated aquorizem and the dosage of washing powder as a flushing agent...
