Chemical compound and disease context of THM

 

Biological context of THM

  • Heritable lympho-epithelial thymoma resulting from a transgene insertional mutation [15].
  • We studied a family bearing the constitutional chromosome translocation t(14;20)(q24;p12), 3 of whose members had a thymoma [1].
  • A thermally assisted hydrolysis and methylation (THM) reaction is described for the determination of delta(13)C fatty acid values using trimethylsulfonium hydroxide (TMSH) [16].
  • A collection of tannins extracted from various plant species was subjected to thermally assisted hydrolysis and methylation (THM) using tetramethylammonium hydroxide [17].
  • Statistical analyses of the THM products and 13C NMR data of the tannins showed good correlations between the B ring hydroxylation and the di- and trimethoxybenzenes observed [17].
 

Anatomical context of THM

  • Thymoma is the most common tumor of the anterior-superior mediastinum [15].
  • Compared with controls, however, microscopic analyses revealed accelerated damage of cellular structure in the aortic root in THM fed with the atherogenic diet [18].
  • This work supports the hypothesis that the local reflex response and the baroreceptor outflow entrain the THM frequency [19].
  • Ribbond THM used under composite restorations increased dentin bond strength in cavities with a high c-factor (p < 0.05) [20].
  • THM levels in drinking water samples from the same communities were compared but analysis of variance computations showed no significant correlation between the water and breast milk [21].
 

Associations of THM with chemical compounds

  • Tannins from species that contained both CT and hydrolyzable tannin (HT) produced mainly permethylated gallic acid moieties upon THM, and the products derived from CTs were less abundant [17].
  • We report on the synthesis of a series of polycationic telomers, polycationic diblock and random polyethylene glycol (PEG)-grafted (co)telomers, and polycationic random tris(hydroxymethyl)methyl (THM) cotelomers, and on their in vitro gene transfer capability [22].
  • Lipoprotein profiles of cholesterol in THM were fundamentally similar to those in C57BL/6J on either the atherogenic or normal diet [18].
  • The THMFP of HiF, normalized on a DOC basis, was found to be comparable to that of AHS (0.176 microM THM mg C(-1) vs. 0.195 microM THM mg C(-1), respectively) [23].
  • The results of this investigation reveal that enhanced coagulation with p-DADMAC was founded to be very effective for removing high-molecular-weight THM precursors, i.e., humic acid and tannic acid, and markedly reduced the alum dosages required for turbidity removal [24].
 

Physical interactions of THM

  • The present study characterizes in vivo and in vitro, functional SS-binding sites in a human thymoma [25].
  • By using immunofluorescence microscopy on stretched single myofibrils, we now report that approximately 40% of the sera from 18 MG/thymoma patients and 8 late-onset MG patients with thymus atrophy contain antibodies that bind to a more central I-band titin region [26].
 

Enzymatic interactions of THM

  • Cytologic findings were retrospectively analyzed in the Papanicolaou-stained stamp smears obtained from the cut surfaces of thymoma specimens [27].
 

Regulatory relationships of THM

  • cDNA clones which seem to represent the alleles of HLA-A and -B expressed by the thymoma MOLT-4 have been isolated and used as locus-specific probes to measure the corresponding mRNA levels in MOLT-4 and other human thymocyte lines, and the effect of interferon (IFN)-alpha and -gamma on these levels [28].
  • Cells of the EL4-6.1 thymoma express large numbers (approximately 20,000 per cell) of IL-1-R that have a Kd of approximately 300 pM for IL-1 [29].
  • However, it has been shown that there is an impairment of CD4+ T cell development in thymoma and that IFN-gamma-induced HLA-DR expression on cultured thymic epithelial cells (TEC) derived from thymoma is decreased when compared with the normal thymus [30].
  • In contrast to CD4+ single-positive cells, most of the CD8+ single-positive cells in the thymoma as well as in the normal thymus expressed CD69 and a high level of CD3 [31].
  • Six thymoma specimens that showed beta gene rearrangement expressed both CD4 and CD8 [32].
 

Other interactions of THM

  • Over a 12-month period, various chemical (THM, HAA, UV254, DOC, TOC, metals, nitrate, nitrites) and physical measurements (lamp voltage, current, sensor measurements) were monitored to define their impact (if any) on the operation of the reactor [33].
  • A continuous cell line (YT cells) with inducible receptor for T cell growth factor (TCGF)/interleukin 2 (IL 2) was established from a 15-yr-old boy with acute lymphoblastic lymphoma and thymoma [34].
  • In addition, the status of ER alpha immunoreactivity was significantly associated with a better clinical outcome in thymoma patients [35].
  • BACKGROUND: Abnormality of the V-akt murine thymoma viral oncogene homologue 1 (AKT1) may be a predisposing factor in schizophrenia [36].
  • A polymorphism in the 3' untranslated region of exon 3 of CDKN2 was detected in 5 cases of thymoma [37].
 

Analytical, diagnostic and therapeutic context of THM

  • Therefore, THM should be a useful animal model for the study on the pathogenesis of atherosclerosis [18].
  • Remarkably, the surface area of atherosclerotic lesion in THM was shown by quantitative image analysis to be 4 times larger than that in C57BL/6J on the same atherogenic diet [18].
  • Epidemiological studies using total THM levels should be taking this into account in the interpretation of their results, and regulatory authorities when setting water guidelines [38].
  • 2. Single oral administration of Val-Tyr (0.1 mg/g) to 11-week-old THM resulted in a prolonged reduction of blood pressure for up to 9 h [39].
  • In our study, we attempted to jointly consider THM concentration data collected from drinking waters and carcinogenic risk assessment derived from mathematical models commonly used in this field (multi-stage models for laboratory animal experimentation data, and 'unit risk' derived from the relative risk in the case of epidemiological data) [40].
