BACKGROUND When the demand placed on the respiratory system is increased, the abdominal muscles become vigorously active to achieve expiration and facilitate subsequent inspiration. Abdominal muscle function could limit ventilatory capacity and a method to detect abdominal muscle fatigue would be of value. The maximum relaxation rate (MRR) of skeletal muscle has been used as an early index of t...
Pteroylglutamic acid (PGA) absorption days. A statistically significant difference was assessed in ten untreated tropical in PGA absorption between TS and consprue (TS) and eight control subjects trol subjects was obtained only when gluutilizing a marker perfusion technique. cose was present in the perfusate. Thus, Physiologic concentrations of the vitamin unequivocal malabsorption of PGA is (2...
Poly-γ-glutamate (PGA) possesses a nylon-like backbone and polyacrylate-like carboxyl groups, and shows an extraordinary solubility in water. In this study, the effective synthesis and structural analysis of some water-insoluble PGA ion-complexes (PGAICs) using cationic surfactants, hexadecylpyridinium (HDP), dodecylpyridinium, benzalkonium and benzetonium, were examined. We demonstrated their ...
Extensive spreading of liquid manure onto agricultural fields causes eutrophication of ground and surface water and also pollution of the atmosphere due to the high ammonium nitrogen content. A poly(gamma-glutamic acid) (PGA)-producing strain of Bacillus licheniformis was isolated in this study and investigated for its ability to reduce the ammonium nitrogen by converting ammonium into biomass ...
PGA (ProGram Algebra) is an algebra of programs which concerns programs in their simplest form: sequences of instructions. Molecular dynamics is a simple model of computation developed in the setting of PGA, which bears on the use of dynamic data structures in programming. We consider the programming of an interpreter for a program notation that is close to existing assembly languages using PGA...
The early identification of graft failure would improve patient management. (18)F-fluoride is a suitable tracer for quantifying bone metabolism. Performance of parametric images constructed by Patlak graphical analysis (PGA) with various time periods was evaluated in the analysis of dynamic (18)F-fluoride PET studies of eight patients with fibula bone grafts after limb salvage surgery. The PGA ...
OBJECTIVE Fixed combination glaucoma medication is increasingly used in glaucoma treatment. There is a lack of comparative study in the literature of non-beta blocker combination agents used adjunctively with a glaucoma agent in a different class. The objective of this study is to evaluate the effect of intraocular pressure (IOP) control and tolerability of non-beta blocker combination suspensi...
Response surface methodology (RSM) was employed to study the effects of four medium components (L-glutamic acid, citric acid, glycerol and NH4Cl) on the production of poly-γ-glutamic acid (PGA) in flask cultures by Bacillus licheniformis CCRC 12826 (ATCC 9945) with initial medium pH 6.5. The optimal PGA yield (35.34 g/L, average of four repeats) was appeared at the region where the respective c...
