The results of studies on the reticulum cell sarcoma (RCS) tumors of SJL/J mice presented here, indicate that spontaneous tumors, which arise in older mice, also possess the capacity to induce the vigorous proliferative response in syngenetic T lymphocytes that are characteristic of the transplantable RCS lines. Analysis of cell surface antigens revealed the presence of Ia determinats on gradie...

The hierarchical real-time control systems (RCS) reference model architecture that is under development at the National Institute of Standards and Technology aims at designing and developing intelligent control for large and complex systems. A methodology being developed to create RCS-based systems exhibits many characteristics that are similar to object-oriented paradigms. The authors compare ...

Polyunsaturated fats have been linked to occurrences of sporadic colon cancer. One possible cause may be degradation of polyunsaturated fats during cooking, resulting in multiple reactive carbonyl species (RCS) that can damage nuclear DNA and proteins, particularly in rapidly dividing colon crypt cells. This study describes a novel antiserum against RCS-modified DNA, with apparent order of reac...

The reticulum cell sarcoma (RCS) 1 of S JL / J mice has been shown to express alien histocompatibility membrane antigens (1, 2). This form of tumor antigen is, by definition, present on cancerous, but not normal, syngeneic tissues. However, it differs from other forms of tumor-associated antigens because it is a normal membrane component of one or more strains allogeneic to the host (3). In the...

Relative clauses (RCs) are subordinate clauses embedded within nominal phrases. Semantically, this embedded clause modifies the dominating nominal head. Syntactically, the nominal head is associated with an empty element within the subordinate clause. RCs have received great attention from language researchers as they demonstrate crucial properties of the human language. They enable recursion i...

Passive radar is a rapidly emerging technology with many distinct advantages over traditional radar. Its exploitation of “illuminators of opportunity” renders it covert, as well as less expensive. Several passive radar systems, such as Lockheed Martin’s Silent Sentry and John Sahr’s Manastash Ridge Radar at the University of Washington, are already capable of detecting and tracking aircraft. Ou...

Intercellular bridges called "ring canals" (RCs) resulting from incomplete cytokinesis play an essential role in intercellular communication in somatic and germinal tissues. During Drosophila oogenesis, RCs connect the maturing oocyte to nurse cells supporting its growth. Despite numerous genetic screens aimed at identifying genes involved in RC biogenesis and maturation, how RCs anchor to the ...

Reactive carbonyls are widespread species in living organisms and mainly known for their damaging effects. The most abundant reactive carbonyl species (RCS) are derived from oxidation of carbohydrates, lipids, and amino acids. Chemical modification of proteins, nucleic acids, and aminophospholipids by RCS results in cytotoxicity and mutagenicity. In addition to their direct toxicity, modificati...

BACKGROUND Robotic-assisted laparoscopy is popularly performed for colorectal disease. The objective of this meta-analysis was to compare the safety and efficacy of robotic-assisted colorectal surgery (RCS) and laparoscopic colorectal surgery (LCS) for colorectal disease based on randomized controlled trial studies. METHODS Literature searches of electronic databases (Pubmed, Web of Science, ...

In Escherichia coli, capsular colanic acid polysaccharide synthesis is regulated through the multistep RcsC-->YojN-->RcsB phosphorelay. By monitoring a hallmarked cps::lacZ reporter gene, we first searched for physiological stimuli that propagate the Rcs signaling system. The expression of cps::lacZ was activated when cells were grown at a low temperature (20 degrees C) in the presence of gluco...
