Effects of a surface-active agent (Spumol BJ) and toxic molasses compounds on development and ultrastructure of Aspergillus niger strain R-16 mycelium producing citric acid in surface fermentation on molasses medium with 80% yield are presented. Microscopic observations showed that Spumol BJ in
OBJECTIVE
Although current bioprosthetic heart valves have low thrombogenicity and favorable hemodynamic properties, their durability remains unsatisfactory. Valve failure usually occurs from calcific degeneration. The study aim was to investigate the effect of a chelating agent, citric acid (CA),
Cough, an important respiratory symptom, predominantly involves the brainstem and the urge-to-cough (UTC) is modulated by the cerebral cortex. Lewy body disease is associated with decreased cough reflex sensitivity and central respiratory chemosensitivity. Additionally, the insula, associated with
An initial transient hyperglycemia was seen in mice injected with asparagine, fluoroacetate, hydroxylamine, or malonate plus methionine, whereas an initial triphasic blood glucose response and a transient "secondary" hyperglycemia were exhibited in those injected with hydroxylamine plus arsenite,
To explore the effect of citric acid (CA)-1-ethyl-3-(3-dimethylaminopropyl)carbodiimide (EDC)/N-hydroxysuccinimide (NHS) collagen gel on repairing annular defects.
Type I collagen was extracted from the rat-tail tendon and crosslinked with CA at different mass ratio using EDC and NHS as crosslinking
Recent studies showed that sodium acid sulfate (SAS) and levulinic acid (LA) in combination with sodium dodecyl sulfate (SDS) was effective in inactivating human pathogens on Romaine lettuce. The present study investigated the effects of LA and SAS in combination with SDS (as compared with citric
Ternary blend films were prepared with different ratios of starch/polyvinyl alcohol (PVA)/citric acid. The films were characterized by field emission scanning electron microscopy (FE-SEM), thermogravimetric analysis, as well as Fourier transform infrared (FTIR) analysis. The influence of different
The bond strength of resins (MMA-TBB resin system), containing 2-hydroxyethyl methacrylate (2-HEMA), 3-methacryloyloxypropionic acid (3MPA), 2-phenylethyl methacrylate (Py1EM) and 2-(1-naphthyl) ethyl methacrylate (NEM), to dentin treated with a solution of 10% citric acid and 3% ferric chloride was
Salivary characteristics are altered in gastrointestinal diseases and related to oral taste disorder. However, specific salivary biochemical characteristics and their relationships with oral taste disturbances in chronic non-atrophy gastritis (CNAG) remain We will present 8 children with progressive infantile or juvenile poliodystrophy (Alpers' disease), associated with a defect in pyruvate metabolism. Laboratory studies showed elevated levels of lactate in CSF and, in 4 children, elevated levels in serum. Histopathologic studies revealed lipid
BACKGROUND
Traumatic injury to the central nervous system results in damage to tissue beyond the primary injury, termed secondary degeneration. Key events thought to be associated with secondary degeneration involve aspects of mitochondrial function which may be modulated by red/near-infrared
The detrimental health implications of chemical preservatives in fruits have necessitated exploitation of safe and natural alternatives such as edible gums. This work studied shelf-life extension in grape (Pinot noir) under cold storage by xanthan gum (XAN) coatings enriched with ascorbic
A method has been elaborated by which degenerating axons can be selectively impregnated with silver. Based on reconsideration of the physicochemical mechanisms of the degeneration methods it takes advantage of physical developers over the chemical ones. The staining procedure is applied to frozen
OBJECTIVE
This study determined the effectiveness of G-coat plus surface protective agent over petroleum jelly on the surface texture of conventional Glass ionomer restorative materials.
METHODS
Three chemically cured conventional glass ionomer restorative materials type II, type IX and ketac molar
Background/Aims
The validity of
13C-urea breath test (
13C-UBT) for
Helicobacter pylori detection is influenced by atrophic gastritis. The aim of this study was to evaluate the effect of
citric acid on the accuracy of
13C-Urea breath test
