התחבר הרשם

Differences in tissue concentrations of N1- and N8-acetylspermidine and cadaverine in squamous cell carcinoma of the oral cavity compared to the surrounding healthy tissue, as well as to epulides and other benign oral lesions (papillomas, lipomas, and fibromas) are assessed. The results indicate

Deactivation of the E. coli pH stress sensor CadC by cadaverine.

התחבר הרשם

At acidic pH and in the presence of lysine, the pH sensor CadC activates transcription of the cadBA operon encoding the lysine/cadaverine antiporter CadB and the lysine decarboxylase CadA. In effect, these proteins contribute to acid stress adaptation in Escherichia coli. cadBA expression is

Identification of the cadaverine recognition site on the cadaverine-lysine antiporter CadB.

התחבר הרשם

Amino acid residues involved in cadaverine uptake and cadaverine-lysine antiporter activity were identified by site-directed mutagenesis of the CadB protein. It was found that Tyr(73), Tyr(89), Tyr(90), Glu(204), Tyr(235), Asp(303), and Tyr(423) were strongly involved in both uptake and excretion

Polyamines of dental plaque in caries-resistant vs. caries-susceptible adults.

התחבר הרשם

Utilizing a sensitive liquid chromatographic system, polyamines were quantitated in three-day plaque from 13 caries-resistant (CR) and 35 caries-susceptible (CS) adults after they had fasted for 12 hours. The values for putrescine and cadaverine were significantly higher in the CR group. This may be

Cadaverine as a putative component of oral malodor.

התחבר הרשם

Whereas previous studies have shown correlations between volatile sulphur compounds (VSC) and bad breath levels, it is probable that other compounds found in the oral cavity may contribute to oral malodor. In the present investigation, the possibility that diamines (cadaverine and putrescine) are

Active site geometry of a novel aminopropyltransferase for biosynthesis of hyperthermophile-specific branched-chain polyamine.

התחבר הרשם

Branched-chain polyamines are found exclusively in thermophilic bacteria and Euryarchaeota and play essential roles in survival at high temperatures. In the present study, kinetic analyses of a branched-chain polyamine synthase from the hyperthermophilic archaeon Thermococcus kodakarensis (Tk-BpsA)

Peritoneal accumulation of infused stroma-free hemoglobin. Potential toxicity of an oxygen-carrying substitute.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

The efficacy of stroma-free hemoglobin (SFH) as an oxygen-carrying red blood cell substitute in shock and trauma remains inconclusive. A major problem is the retention of sufficient intravascular persistence. The sites and mechanisms for clearance of SFH or its chemically modified variants are not

Mapping of transglutaminase 2 sites of human salivary small basic proline-rich proteins by HPLC high resolution ESI-MS/MS.

התחבר הרשם

Due to the distinctive features of oral cavity, determination of the proteins involved in the formation of "oral protein pellicle" is demanding. The present study investigated the susceptibility of several human basic proline-rich peptides, named P-H, P-D, P-F, P-J, and II-2 as substrates

Pellicle precursor proteins: acidic proline-rich proteins, statherin, and histatins, and their crosslinking reaction by oral transglutaminase.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

Previous studies have demonstrated that whole saliva and pellicle formed in vitro from oral fluid contain covalently crosslinked salivary proteins. The purpose of this study was to determine which salivary proteins can act as substrates for transglutaminase, an enzyme responsible for the covalent

The interaction of xenon with copper/6-hydroxydopa (2,4,5-trihydroxyphenethylamine) quinone (TPQ) amine oxidases from the plant pulses lentil (Lens esculenta) and pea (Pisum sativum) (seedlings), the perennial Mediterranean shrub Euphorbia characias (latex), and the mammals cattle (serum) and pigs

Host-guest complexes of imazalil with cucurbit[8]uril and β-cyclodextrin and their effect on plant pathogenic fungi.

התחבר הרשם

We report the control of imazalil (IMZ) antifungal activity utilizing its non-covalent assembly with β-cyclodextrins (β-CD) and cucurbit[8]uril (CB8) macrocycles, as well as its stimuli-responsive disassembly with cadaverine. The NMR results are consistent with inclusion of a single IMZ molecule

Crystal structure of the sensory domain of Escherichia coli CadC, a member of the ToxR-like protein family.

רק משתמשים רשומים יכולים לתרגם מאמרים

התחבר הרשם

The membrane-integral transcriptional activator CadC comprises sensory and transcriptional regulatory functions within one polypeptide chain. Its C-terminal periplasmic domain, CadC(pd), is responsible for sensing of environmental pH as well as for binding of the feedback inhibitor cadaverine. Here

Reduction of oral malodor by oxidizing lozenges.

התחבר הרשם

The main purpose of the study was to examine the anti-malodor properties of oxidizing lozenges, as compared to breath mints and chewing gum. Healthy, young adult volunteers (N = 123; mean age 24.5 years) were measured for oral malodor-related parameters (whole mouth odor measured by 2 judges; tongue

Role of biogenic amines in the post-mortem migration of Anisakis pegreffii (Nematoda: Anisakidae Dujardin, 1845) larvae into fish fillets.

Infective third-stage larvae (L3) of nematode Anisakis spp. have been recognized as one of the major food-borne threats in lightly processed fish products in Europe, particularly in the Mediterranean region. Therefore, the effect of different storage temperatures of fish on larval post-mortem

Structural Investigations of N-carbamoylputrescine Amidohydrolase from Medicago truncatula: Insights into the Ultimate Step of Putrescine Biosynthesis in Plants.

התחבר הרשם

Putrescine, 1,4-diaminobutane, is an intermediate in the biosynthesis of more complexed polyamines, spermidine and spermine. Unlike other eukaryotes, plants have evolved a multistep pathway for putrescine biosynthesis that utilizes arginine. In the final reaction, N-carbamoylputrescine is hydrolyzed
