Inadequate Folic Acid Intake Among Women Taking Antiepileptic Drugs During Pregnancy in Japan: A Cross-Sectional Study

This study aimed to assess characteristics of pregnant women taking antiepileptic drugs with inadequate folic acid intake. This cross-sectional study examined pregnant women taking antiepileptic drugs who were registered in the Japanese Drug Information Institute in Pregnancy (JDIIP) database between October 2005 and December 2016. Participants were classified into two groups according to when they started folic acid supplementation (before pregnancy: ‘adequate’, after pregnancy or never: ‘inadequate’). Logistic regression analysis was performed to investigate factors associated with inadequate folic acid intake. Of 12,794 registrants, 468 pregnant women were taking antiepileptics during the first trimester. Of these, we analysed data from 456 women who had no missing data. As a result, inadequate folic acid intake was noted among 83.3% of them, suggesting that the current level of folic acid intake is insufficient overall. Younger age, smoking, alcohol drinking, multiparity, unplanned pregnancy, and being prescribed AEDs by paediatric or psychiatric departments were independent factors associated with inadequate folic acid intake. As planned pregnancy was the strongest factor, healthcare professionals should ensure that childbearing women taking antiepileptics are informed of the importance of planned pregnancy. In addition, healthcare professionals must gain a better understanding of folic acid intake, as the prevalence of adequate intake differed according to which departments prescribed antiepileptic drugs

Inhibitory effects of RAGE-aptamer on development of monocrotaline-induced pulmonary arterial hypertension in rats

Background: The receptor for advanced glycation end products (RAGE), a transmembrane receptor belonging to the immunoglobulin superfamily, is overexpressed in pulmonary artery smooth muscle cells (PASMCs) in patients with pulmonary arterial hypertension (PAH) and is implicated in the etiology of PAH. Recently, we reported that RAGE-aptamer, a short and single-stranded DNA directed against RAGE, inhibited an inappropriate increase in cultured PASMCs in PAH. The aim of this study was to determine the efficacy of RAGEaptamer in monocrotaline-induced PAH in rats. Methods and Results: Rats were assigned to either an untreated control group, a group that received continuous subcutaneous administration of RAGE-aptamer immediately after monocrotaline injection, or a group that received control-aptamer immediately after monocrotaline injection. All rats survived 21 days after injection of monocrotaline and control-aptamer or RAGE-aptamer. Injection of monocrotaline with continuous subcutaneous delivery of control-aptamer resulted in higher right ventricular systolic pressure compared with controls. This increase was attenuated by continuous subcutaneous delivery of RAGE-aptamer. The proportion of small pulmonary arteries with full muscularization was greater in the monocrotaline and control-aptamer group than in the control group. Continuous subcutaneous delivery of RAGE-aptamer significantly reduced the percentage of small pulmonary arteries with full muscularization Conclusions: Continuous subcutaneous delivery of RAGE-aptamer suppresses development of monocrotaline-induced PAH in rats. Inhibition of RAGE ameliorates muscularization of 3 small pulmonary arteries. Treatment with RAGE-aptamer might be a new therapeutic option for PAH

Management of Natural History collections: criteria and parameters of evaluation

[ES] Las colecciones de historia natural son una herramienta básica para la investigación científica y el estudio de la distribución en el pasado de muchas especies, así como de la propia historia de la ciencia. Además del uso científico de estas colecciones, destacan otros como el histórico, el divulgativo-pedagógico y el estético. De ahí la importancia que tiene una gestión eficaz de las mismas, la cual implica diversos aspectos, que van desde la conservación y su mantenimiento, su inventario, ordenación y procesamiento informático hasta las múltiples tareas relacionadas con su uso en consultas, visitas, préstamos científicos y participación en actividades de carácter divulgativo. En este artículo se examinan los criterios para evaluar la gestión de las colecciones de historia natural y se definen una serie de parámetros, útiles para medir el estado de una colección y su evolución en el tiempo, tanto en su crecimiento como en su uso, principalmente. Se ejemplifica todo ello en el grupo de los poliquetos, del que el Museo Nacional de Ciencias Naturales de Madrid (MNCN) cuenta con una estimable colección, y se comparan los resultados, según varios parámetros seleccionados, con los de otras colecciones de poliquetos de diversas instituciones de todo el mundo.[EN] Natural History collections are a basic and essential tool for scientific research, the study of the distribution in the past of many species of animals and plants and the History of Science. As well as the scientific aspect of these collections, stand outs other uses as the historic one, the educational and the aesthetic. All these are reasons that show the importance of an effective management of the Natural History collections as well as the several tasks related to it, as consults, visits, scientific loans and educational activities. In this article various criteria and useful parameters are provided for evaluating the curatorial state of a Natural History collection and its evolution, both in growth and use mainly. Finally, an example based on the Polychaeta, an estimable group in the Invertebrates Collection of the Museo Nacional de Ciencias Naturales of Madrid (MNCN), is provided. The results of several selected parameters are compared with other Polychaeta collections from several institutions around the world.Peer reviewe

Development of a mugineic acid family phytosiderophore analog as an iron fertilizer

Iron (Fe) is an essential nutrient, but is poorly bioavailable because of its low solubility in alkaline soils; this leads to reduced agricultural productivity. To overcome this problem, we first showed that the soil application of synthetic 2′-deoxymugineic acid, a natural phytosiderophore from the Poaceae, can recover Fe deficiency in rice grown in calcareous soil. However, the high cost and poor stability of synthetic 2′-deoxymugineic acid preclude its agricultural use. In this work, we develop a more stable and less expensive analog, proline-2′-deoxymugineic acid, and demonstrate its practical synthesis and transport of its Fe-chelated form across the plasma membrane by Fe(III)•2’-deoxymugineic acid transporters. Possibility of its use as an iron fertilizer on alkaline soils is supported by promotion of rice growth in a calcareous soil by soil application of metal free proline-2’-deoxymugineic acid

Bortezomib-cyclophosphamide-dexamethasone induction/consolidation and bortezomib maintenance for transplant-eligible newly diagnosed multiple myeloma: phase 2 multicenter trial

[Objectives:] We conducted a phase II trial to prospectively evaluate the efficacy and safety of bortezomib-cyclophosphamide-dexamethasone (VCD) induction, autologous stem cell transplantation (ASCT), VCD consolidation, and bortezomib maintenance in transplant-eligible newly diagnosed multiple myeloma (NDMM) patients in Japan (UMIN000010542). [Methods:] From 2013 to 2016, 42 patients with a median age of 58 (range 42–65) years with NDMM were enrolled in 15 centers. The primary endpoint was the complete response (CR) /stringent CR (sCR) rate after transplantation, and overall/progression-free survival rates were also evaluated. [Results:] Following induction therapy, the overall response rate was obtained in 71% of patients, including a CR/sCR of 10% and a very good partial response (VGPR) of 26%. Twenty-six of the 42 patients completed ASCT following the protocol and CR/sCR and VGPR rate 100 days after ASCT was 26% and 17%, respectively. During consolidation therapy, 3 of the 24 patients achieved deeper responses. Eight of the 18 patients completed 2-year bortezomib maintenance without disease progression and grade 3/4 toxicities. Five patients were VGPR or partial response after ASCT but maintained response with 2-year bortezomib maintenance. Two-year overall and progression-free survival rates were 92.5% (95% confidence interval [CI]: 78.5%−97.5%) and 62.6% (95% CI: 45.8%−75.5%), respectively. Grade 3/4 toxicities (≥ 10%) included neutropenia (19%) and anemia (17%) in induction, and thrombocytopenia (29%) in consolidation. [Conclusion:] VCD induction/consolidation and bortezomib maintenance with ASCT for NDMM resulted in a high CR/sCR rate and provided good overall/progression-free survival in Japan

静止衛星データの全球合成技術の開発

Mucopolysaccharidosis type II (MPS II, Hunter syndrome) is an X-linked genetic disorder caused by a deficiency of iduronate 2-sulfatase (IDS), and missense mutations comprising about 30% of the mutations responsible for MPS II result in heterogeneous phenotypes ranging from the severe to the attenuated form. To elucidate the basis of MPS II from the structural viewpoint, we built structural models of the wild type and mutant IDS proteins resulting from 131 missense mutations (phenotypes: 67 severe and 64 attenuated), and analyzed the influence of each amino acid substitution on the IDS structure by calculating the accessible surface area, the number of atoms affected and the root-mean-square distance. The results revealed that the amino acid substitutions causing MPS II were widely spread over the enzyme molecule and that the structural changes of the enzyme protein were generally larger in the severe group than in the attenuated one. Coloring of the atoms influenced by different amino acid substitutions at the same residue showed that the structural changes influenced the disease progression. Based on these data, we constructed a database of IDS mutations as to the structures of mutant IDS proteins
