Publisher Summary This chapter discusses that the suppressor mutations are one class of secondary mutations that modify the phenotype in the presence of the originally mutant gene. In contrast to “enhancers” that make the mutant phenotype more extreme, suppressor mutations yield organisms phenotypically more like the wild type: The mutant phenotype ...

Cannabinoid Mechanisms of Pain Suppression
2005A large body of literature indicates that cannabinoids suppress behavioral responses to acute and persistent noxious stimulation in animals. This review examines neuroanatomical, behavioral, and neurophysiological evidence supporting a role for cannabinoids in suppressing pain at spinal, supraspinal, and peripheral levels.

Mechanisms of uremic suppression of appetite
Journal of Renal Nutrition, 1999Food intake is regulated by short-term satiety factors (gastric distension, amino acids, peptide hormones), as well as factors involved in long-term appetite regulation (leptin, insulin). Integration of the various signals takes place in the central nervous system (CNS). Appetite suppression in uremia is multifactorial and may include effects of uremia

MECHANISMS OF SUPPRESSION IN MIXED ALLOGENEIC CHIMERAS
Transplantation, 1988Cells with the ability to suppress cytotoxic T lymphocyte generation are found in the spleens of whole-body-irradiated (WBI) mixed allogeneic and syngeneic bone marrow transplant recipients in the early weeks after BMT. Previous studies have indicated that suppression is mediated by "null cells" similar to natural suppressor (NS) cells (1), and have ...

The mechanism of oscillopsia and its suppression
Annals of the New York Academy of Sciences, 2011We studied the mechanisms of oscillopsia suppression in subjects with infantile nystagmus syndrome, fusion maldevelopment nystagmus syndrome, and acquired nystagmus (AN). Hypothetical possibilities for perceptual stability were the following: (1) epochs of clear and stable vision during foveation periods of nystagmus waveforms; (2) cancellation by ...

Mechanisms for Corruption Suppression [PDF]
Journal of the New Economic Association, 2011 Government agencies and large corporations meet similar problems related to control of agents dealing with outsiders: citizens under audit of the agency or clients of the company. In such interaction there typically exists a possibility of collusion. In order to prevent it, agencies and corporations usually organize hierarchical controlling structures.

Mechanism for Optical Enhancement and Suppression of Fluorescence
The Journal of Physical Chemistry A, 2009When fluorescence from electronically excited states follows the absorption of radiation, the emission spectrum is often a key to identification of the excited species. It now emerges that passing off-resonant laser light through such an electronically excited system may enhance or suppress the fluorescent emission.

A Mechanism for the Suppression of Ongoing IgE Synthesis
International Archives of Allergy and Applied Immunology, 2009IgE synthesis from the human plasmacytoma U266/AF-10 was suppressed by addition of IgE immune complexes (IgE-IC). This suppression was isotype-specific as synthesis from other B cell lines was unaffected. Using IgE-IC constructed with a monoclonal antibody that recognizes PS protein-IgE and not ND IgE (the IgE protein made by U266/AF-10), we have shown

Mechanisms underlying the suppression of erythropoiesis by hyperoxia
The American Journal of the Medical Sciences, 1977The possible mechanisms underlying the suppression of erythropoiesis in hyperoxic animals were studied. Male Long-Evans rats were injected with cobaltous chloride hexahydrate, a known erythropoietic stimulant. One group was exposed to a hyperoxic environment for ten hours.

Mechanisms of Idiotype Suppression
The Journal of Immunology, 1979Abstract Specific tolerance of BALB/c spleen cells to phosphorylcholine (PC) was induced in vitro by treatment with antibodies specific for the idiotype of TEPC-15 myeloma protein (anti-T15id) and a PC-containing antigen, R36a. The presence of anti-T15id antibody for at least 2 days was necessary to achieve a full level of suppression ...
