Impact of hydration state and molecular oxygen on the chemical stability of levothyroxine sodium.
Pharm. Dev. Technol. 20(3) , 314-9, (2015) Levothyroxine sodium is an important medication used primarily for treating patients with hypothyroidism. Levothyroxine sodium tablets have been recalled many times since their 1955 introduction to the US market. These recalls resulted from the failure of lot... |

Immunoexpressions of embryonic and nonembryonic stem cell markers (Nanog, Thy-1, c-kit) and cellular connections (connexin 43 and occludin) on testicular tissue in thyrotoxicosis rat model.
Hum. Exp. Toxicol. 34 , 601-11, (2015) In this study, possible thyrotoxicosis-related histological changes in testicular tissues of rats with experimentally induced thyrotoxicosis model were evaluated on cellular connections and stem cell markers. Two experimental groups, thyrotoxicosis and contro... |

A Convenient and Efficient Method to Enrich and Maintain Highly Proliferative Human Fetal Liver Stem Cells.
Rejuvenation Res. 18 , 211-24, (2015) Pluripotent human hepatic stem cells have broad research and clinical applications, which are, however, restricted by both limited resources and technical difficulties with respect to isolation of stem cells from the adult or fetal liver. In this study, we de... |

A radioimmunoassay for measurement of thyroxine sulfate.
J. Clin. Endocrinol. Metab. 76(1) , 145-50, (1993) A highly sensitive, specific, and reproducible RIA has been developed to measure T4 sulfate (T4S) in ethanol extracts of serum. rT3 sulfate (rT3S) cross-reacted 7.1%, and T3S cross-reacted 0.59% in the RIA; T4, T3, rT3, and 3,3'-diiodothyronine cross-reacted ... |

Characterization of the regulatory mechanisms of activating transcription factor 3 by hypertrophic stimuli in rat cardiomyocytes.
PLoS ONE 9(8) , e105168, (2014) Activating transcription factor 3 (ATF3) is a stress-activated immediate early gene suggested to have both detrimental and cardioprotective role in the heart. Here we studied the mechanisms of ATF3 activation by hypertrophic stimuli and ATF3 downstream target... |

Increased levels of the pro-inflammatory prostaglandin PGE2 in CSF from ALS patients.
Neurology 58(8) , 1277-9, (2002) Levels of the potent pro-inflammatory prostaglandin E(2) (PGE(2)) are elevated in postmortem spinal cords from patients with ALS, and inhibition of a key PGE(2)-synthesizing enzyme, cylcooxygenase-2, is neuroprotective in an in vitro model of ALS. The authors... |

T4, T3 and rT3 levels in serum and cerebrospinal fluid of patients with amyotrophic lateral sclerosis.
J. Neurol. 236(1) , 57-9, (1989) Thyronine (T4), triiodothyronine (T3), and reverse-triiodothyronine (rT3) levels were evaluated in cerebrospinal fluid (CSF) and in serum of 12 patients with definite amyotrophic lateral sclerosis (ALS) by specific radioimmunoassays. Circulating microsomal an... |

Raised nitrate concentration and low SOD activity in the CSF of sporadic ALS patients.
Neurochem. Res. 28(5) , 699-703, (2003) To determine whether or not the occurrence of sporadic amyotrophic lateral sclerosis (sALS) is associated with both excess nitric oxide (NO) metabolites and decreased protective superoxide dismutase (SOD) activity in the cerebrospinal fluid (CSF), we measured... |

Organ-specific matrix self-assembled by mesenchymal cells improves the normal urothelial differentiation in vitro.
World J. Urol. 34 , 121-30, (2016) Enterocystoplasty is the gold standard to perform bladder reconstruction. Since this technique has a high morbidity rate, several matrix scaffolds have been proposed to support the urothelial maturation. Unfortunately, epithelial cells failed to fully integra... |

Measurement of triiodothyronine in urine.
Tohoku J. Exp. Med. 132(4) , 389-95, (1980) A radioimmunoassay procedure to measure triiodothyronine (T3) in unextracted urine is described. One hundred microliter of T3 standards or samples were incubated with 100 microliter of T3 antiserum (1:40,000), 100 microliter of tracer 125I-T3 and 700 microlit... |
