Amino Acids Sample Clauses

Amino Acids. The amino acid arginine promotes swarming under non-permissive conditions, particularly those of low pH, but arginine biosynthesis mutants swarm normally indicating the intracellular production of this amino acid does not contribute to swarming under normal laboratory conditions (23). However, the mechanism by which extracellular arginine and SpeA (arginine decarboxylase) contribute to swarming was later elucidated. The SpeA-mediated conversion of arginine to agmatine consumes intracellular protons, conserving the proton gradient and proton motive force during swarming in low pH environments (282). Glutamine is required for swarming, and P. mirabilis encodes genes specific for glutamine synthesis and transport (23, 25). On media non-permissive for swarming motility, only glutamine was able to initiate differentiation (25). Mutants in glnA encoding glutamine synthetase are completely unable to swarm on rich media, and only L-glutamine restored swarming in this mutant. However, no data exists suggesting exogenous glutamine triggers differentiation, though cells migrate for slightly longer distances prior to consolidation (23). Glutamine may promote migration but it does not seem to trigger differentiation. Overall, amino acids have been shown to trigger differentiation and promote migration. They may be sensed by P. mirabilis to determine if surroundings are ideal for the initiation of swarming or if entry into consolidation phase is warranted.

Amino Acids. The German BLS database reports “essential amino acids” and “non-essential amino acids”. For the Component Thesaurus version 1.2, “amino acids, total essential; eight essential amino acids” [AAE8] was added, corresponding to the equivalent INFOODS tagname. If the value is for the total of isoleucine, leucine, lysine, methionine, phenylalanine, threonine, tryptophan and valine, this identifier should be used. If the total conforms to one of the INFOODS tagnames AAE10A, AAE10B or AAE12, the identifier AAE10B exists or the other identifiers should be considered for the EuroFIR Thesaurus. If the definition for the total is unknown, the identifier AAE- should be used. It is noted that the April 2010 INFOODS proposals (INFOODS, 2010) add the codes AAE7 and AAE9 for essential amino acid totals and AAT19, AAT20 and AAT24 for overall amino acid totals.

  • Preceptor A per diem Registered Nurse 2 may serve as a preceptor after successfully completing a preceptor workshop or equivalent documented training and agreeing to and being appointed to be specifically responsible for planning, organizing, and evaluating the new skill development of one or more RNs as appropriate enrolled in a defined orientation program, the parameters of which have been set forth in writing by the Employer. This includes teaching, clinical supervision, role modeling, feedback, evaluation (verbal and written) and follow up of the new or transferring employee. The per diem RN 2 preceptor is eligible to receive preceptor premium pay when actually engaged in preceptor role responsibilities with/on behalf of the orienting RN. A per diem RN 2 substituting for the original preceptor during a period of absence and who has been designated to carry out the preceptor's complete responsibility (including following and/or adjusting the plan to meet learning needs and providing oral and written evaluation input) will receive preceptor pay. A preceptor may be assigned to a student when it is determined by the Employer that the employee has completed the required preceptor training or has agreed to and been appointed a preceptor. The employee is specifically responsible for planning, organizing, and evaluating the new skill development of the student as appropriately enrolled in a defined program, the parameters of which have been set forth in writing by the Employer. This includes teaching, clinical supervision, role modeling, feedback, evaluation (verbal and written) and follow up of the student.
