- 1. ヨード欠乏症iodine deficiency disorders [show details]
… Both insufficient and excessive iodine intake can result in thyroid disease. The term "iodine deficiency disorders" refers to all of the consequences of iodine deficiency, which depend on its severity …
- 2. 食物中の微量ミネラルの概要overview of dietary trace minerals [show details]
… epidemiology of iodine deficiency is described in greater detail in a separate topic review. Iodine is heterogeneously distributed in the environment, with soil and water varying greatly in their iodine content… Ceruloplasmin binds to its receptors on the cell surface; copper is then released from its binding protein and enters the cell.…
- 3. ヨード誘発性甲状腺機能異常症iodine induced thyroid dysfunction [show details]
… The central role of iodide in thyroid physiology has been known for many years. The four iodine atoms of thyroxine (T4) constitute 65 percent of its weight; the three iodine atoms of triiodothyronine …

- Phthalides serve as potent modulators to boost fetal hemoglobin induction therapy for β-hemoglobinopathies.
- Chen WR, Chou CC, Wang CC.
- Blood advances. 2019 May;3(9)1493-1498.
- Fetal hemoglobin (HbF) induction therapy has become the most promising strategy for treating β-hemoglobinopathies, including sickle-cell diseases and β-thalassemia. However, subtle but critical structural difference exists between HbF and normal adult hemoglobin (HbA), which inevitably leads to re

- Journal of proteomics. 2019 Feb;192()10-17.
- Thermal proteome profiling (TPP) is increasingly applied in eukaryotes to investigate protein-ligand binding through protein melting curve shifts induced by the presence of a ligand. In anaerobic bacteria, identification of protein-substrate interactions is a major challenge. We applied TPP to Sulfu
