Toxicological Profile of Ultrapure 2,29,3,4,49,5,59- Heptachlorbiphenyl (PCB 180) in Adult Rats
2014
Abstract: PCB 180 is a persistent non-dioxin-like polychlorinated biphenyl (NDL-PCB) abundantly present in food and the environment. Risk characterization of NDL-PCBs is confounded by the presence of highly potent dioxin-like impurities. We used ultrapure PCB 180 to characterize its toxicity profile in a 28-day repeat dose toxicity study in young adult rats extended to cover endocrine and behavioral effects. Using a loading dose/maintenance dose regimen, groups of 5 males and 5 females were given total doses of 0, 3, 10, 30, 100, 300, 1000 or 1700 mg PCB 180/kg body weight by gavage. Dose- responses were analyzed using benchmark dose modeling based on dose and adipose tissue PCB concentrati…
Safety of Tyrosine Kinase Inhibitors in Patients With Differentiated Thyroid Cancer: Real-World Use of Lenvatinib and Sorafenib in Korea
2019
Background: Thyroid cancer has become the most common cancer in Korea. Generally, thyroid cancer patients have a good prognosis; however, 15–20% of patients experience recurrence or distant metastasis or are refractory to standard treatment. We assessed the safety of sorafenib and lenvatinib in patients with advanced or metastatic radioactive iodine-refractory differentiated thyroid cancers (DTC) consecutively treated at a tertiary center in South Korea.Methods: We retrospectively reviewed the charts of all consecutive patients with DTC treated during ≥6 months with lenvatinib (February 2016–April 2018) and sorafenib (January 2014–April 2018) at Gangnam Severance Hospital. Patients were tre…
Population divergence in maternal investment and embryo energy use and allocation suggests adaptive responses to cool climates
2023
1. The thermal sensitivity of early life stages can play a fundamental role in constraining species distributions. For egg-laying ectotherms, cool temperatures often extend development time and exacerbate developmental energy cost. Despite these costs, egg laying is still observed at high latitudes and altitudes. How embryos overcome the developmental constraints posed by cool climates is crucial knowledge for explaining the persistence of oviparous species in such environments and for understanding thermal adaptation more broadly. 2. Here, we studied maternal investment and embryo energy use and allocation in wall lizards spanning altitudinal regions, as potential mechanisms that enable su…

ANAPLASTIC THYROID CANCER: A CASE SERIES WITH A WIDE SPECTRUM OF TREATMENT IN EMERGENCY
2019
Anaplastic thyroid carcinoma (ATC) is one of the most aggressive malignancies of the neck, and for the majority of these patients the cause of death is a compromised airway, metastatic disease, superior vena cava syndrome, asphyxiation, or exsanguination. In case of the airway being compromised, emergency treatment is mandatory but not well defined. We report 4 different kinds of acute presentation of complications. Anaplastic thyroid cancer; diagnostic, clinical and prognostic indication, evaluation of choice of treatment are discussed. The spectrum of treatment varies from observation and preservation of the airway from a tracheostomy to extensive surgery. When a potentially curative rese…
Burning mouth syndrome (BMS) : evaluation of thyroid and taste
2006
Background Burning mouth syndrome (BMS) is a chronic, intraoral burning sensation seen mainly in middle-aged and post-menopausal females, without identifiable oral lesions or abnormal laboratory findings, but often associated with psychogenic disorders such as depression. The latter can have a range of causes, including hormonal. Objective Since there may be connections between BMS, psychogenic changes, hormonal changes and taste abnormalities , we have examined aspects of taste and thyroid function.. Patients and methods We selected 50 patients with BMS (study group) and 50 healthy subjects (control group) and analysed their ability to taste bitter, acid and spicy substances and analysed t…
Prenatal thyroid hormones accelerate postnatal growth and telomere shortening in wild great tits
2021
AbstractEarly-life environment is known to affect later-life health and disease, which could be mediated by the early-life programming of telomere length, a key hallmark of ageing. According to thefetal programming of telomere biology hypothesis, variation in prenatal exposure to hormones is likely to influence telomere length. Yet the contribution of key metabolic hormones,i.e. thyroid hormones (THs), has been largely ignored. We recently showed that in contrast to predictions, exposure to elevated prenatal THs increased postnatal telomere length in wild collared flycatchers, but the generality of such effect, its underlying proximate mechanisms and consequences on survival have not been i…
