The planarian Dugesia japonica can regenerate a complete individual from a head, trunk or tail fragment via activation of somatic pluripotent stem cells. About a century ago, Thomas Hunt Morgan attempted to explain the extraordinary regenerative ability of planarians by positing two opposing morphogenetic gradients of formative "head stuff" and "tail stuff"… (More)
Central nervous system (CNS) relapse is an uncommon devastating complication of diffuse large B-cell lymphoma (DLBCL) that usually occurs within 2 years from initial diagnosis. Its pathophysiology is poorly understood and there is no consensus on the definition of high-risk patients for CNS relapse. Consequently, an empirical and highly variable practice of… (More)
An increase in coronary flow-velocity reserve may be one of the important cardioprotective effects of red wine. Some polyphenols may have potent vasorelaxing effects on coronary microvessels during hyperaemia.
To test whether interferon can prevent acute non-A, non-B hepatitis from becoming chronic, a prospective controlled trial was conducted in 25 patients; 11 were treated for an average of 30 days with a mean of 52 megaunits of interferon and 14 acted as controls. 4 patients in the treatment group who continued to have raised serum aminotransferase… (More)
We established a laboratory clonal strain of freshwater planarian (Dugesia japonica) that was derived from a single individual and that continued to undergo autotomous asexual reproduction for more than 20 years, and we performed large-scale genome sequencing and transcriptome analysis on it. Despite the fact that a completely clonal strain of the planarian… (More)
The distribution curves of urinary red-blood-cell (RBC) size were obtained from automated blood-cell analysis in 146 patients with definite causes of haematuria. In 65 of 67 patients (97%) with haematuria and glomerulonephritis demonstrated by renal biopsy, urinary RBC had an irregular and asymmetrical distribution with RBC size showing a much smaller… (More)
An orphan medicinal product, eculizumab is approved in Japan and globally for treating paroxysmal nocturnal hemoglobinuria and atypical hemolytic uremic syndrome. Eculizumab therapy can cause late complement pathway deficiencies that predispose patients to meningococcal infections. Although meningococcal vaccinations are typically considered mandatory for… (More)
