The Reticulum Cell Sarcoma (RCS)' is a spontaneous lymphatic tumor of the SJL/J (H-29) mouse, first observed by Murphy (1) in upwards of 90% of SJL/J mice of amean age of 13 .3 mo. RCS tumors are considered B cell lineage neoplasms that exhibit Ig H chain gene rearrangements, but no surface or cytoplasmic Ig (2). Additionally, RCS tumors express IAs MHC-encoded polypeptides (3) . RCS tumors req...

The effect of light- and dark-rearing on the amounts of rhodopsin and interstitial retinol-binding protein (IRBP) in RCS rats and their congenic controls (RCS-rdy+) was determined. Rhodopsin was measured spectroscopically and IRBP by dot-blot enzyme immunoassay utilizing rabbit antibovine IRBP IgG. After P15-20, dark-reared RCS and RCS-rdy+ rats always had more rhodopsin than their light-reared...

The Rcs phosphorelay system, a non-orthodox two-component regulatory system, integrates environmental signals, regulates gene expression, and alters the physiological behavior of members of the Enterobacteriaceae family of Gram-negative bacteria. Recent studies of Rcs system focused on protein interactions, functions, and the evolution of Rcs system components and its auxiliary regulatory prote...

The objective of this study was to illustrate how different methods of obtaining the Radar Cross Section (RCS) of an object may produce different results. RCS diagrams of a metallic airplane model (length, 0.64 m) were obtained in an anechoic chamber, with a LabVolt RCS system, and simulated with a simulation software. The measurements and simulations were carried out at the radar frequency of ...

The retrosternal clear space (RCS) is a lucent area on the lateral chest radiograph located directly behind the sternum. The two types of pathology classically addressed in the RCS are anterior mediastinal masses and emphysema. Diseases of the pulmonary interstitium are a third type of pathology that can be seen in the RCS. Retrosternal reticular opacities, known as Kerley D lines, were initial...

The far-field Radar Cross Section (RCS) measurement of the actual target requires a long measurement range, which can be realized in the outdoor site. One of the problems in outdoor measurement is the difficulty to avoid the effect of ground bounce. Some sites overcome the difficulty by the exploitation of the ground bounce in RCS measurement [1][2]. Meanwhile the RCS measurement of the large a...

Picornavirus RNA replication requires the formation of replication complexes (RCs) consisting of virus-induced vesicles associated with viral nonstructural proteins and RNA. Brefeldin A (BFA) has been shown to strongly inhibit RNA replication of poliovirus but not of encephalomyocarditis virus (EMCV). Here, we demonstrate that the replication of parechovirus 1 (ParV1) is partly resistant to BFA...

Some background describing the rationale and early development of regional curve standardization (RCS) is provided. It is shown how, in the application of RCS, low-frequency variance is preserved in the mean values of individual series of tree indices, while medium-frequency variance is also preserved in the slopes. Various problems in the use of the RCS approach are highlighted. The first prob...

Two congenic strains of RCS rats, RCS-p/+ and RCS-c, have been developed that differ from the parental strain at genetic loci affecting pigmentation. Inbred RCS rats are pink-eyed, while RCS-p/+ rats produce segregating litters of pink-eyed (p/p) and black-eyed (p/+) offspring, and RCS-c rats are albinos. All the strains are homozygous for the mutant form of the retinal dystrophy gene. The blac...
