The assessment of surgical and non-surgical treatment of stage II medication-related osteonecrosis of the jaw

Non-surgical treatment has generally been recommended for stage II medication-related osteonecrosis of the jaw (MRONJ) in preference to surgery. However, non-surgical treatment is not empirically effective. The aim of this study was to evaluate whether surgical or non-surgical treatment leads to better outcomes for stage II MRONJ. In this retrospective study, surgery was performed in a total of 28 patients while 24 patients underwent non-surgical treatment. The outcomes of both treatment approaches after 6 months were evaluated and statistically compared. In addition, risk factors for surgical and non-surgical treatments were assessed for each. Surgical treatment in 25 patients (89.3%) resulted in success, with failure in 3 patients (10.7%). Non-surgical treatment was successful for 8 patients (33.3%) and failed in 16 patients (66.7%). There was therefore a significant difference between surgical and non-surgical treatment outcomes (P<0.01). Regarding risk factors, in non-surgical treatment primary diseases, medications, and drug holiday had a significant effect on outcomes (P<0.01). Risk factors for surgical treatment could not be clarified. Surgical treatment is more effective than non-surgical treatment for stage II MRONJ, and drug holiday, primary disease, and medication constitute risk factors in non-surgical treatment

Expression of human thromboxane synthase using a baculovirus system

AbstractHuman thromboxane (TX) synthase (EC 5.3.99.5) was produced by the baculovirus expression system using cDNA encoding human TX synthase [(1991) Biochem. Biophys. Res. Commun. 78, 1479-1484]. A recombinant baculovirus TXS7 was expressed in Spodoptera frugiperda Sf9 insect cells. The expressed protein was recognized by monoclonal antibody, Kon 7 raised against human TX synthase [(1990) Blood 76, 80-85]. The recombinant TX synthase catalyzed the conversion of prostaglandin (PG) H2 to TXA2 and 12-hydroxy-heptadecatrienoic acid (HHT). Both conversions of PGH2 to TXA2 and HHT by the expressed TX synthase were completely inhibited by a specific TX synthase inhibitor, OKY-046 (5 μM)

Towards a greater global understanding of wellbeing: A proposal for a more inclusive measure

The science of wellbeing has come a long way from the early days of measuring wellbeing via a nation’s GDP, and wellbeing measures and concepts continue to proliferate to capture its various elements. Yet, much of this activity has reflected concepts from Western cultures, despite the emphasis placed on wellbeing in all corners of the globe. To meet the challenges and opportunities arising from cross-disciplinary research worldwide, the Well-Being for Planet Earth Foundation and the Gallup World Poll have joined forces to add more culturally relevant constructs and questions to existing Gallup modules. In this white paper, we review the discussion from the international well-being summit in Kyoto, Japan (August 2019), where nine such additions were proposed and highlight why a more global view of wellbeing is needed. Overall, the new items reflect a richer view of wellbeing than life satisfaction alone and include hedonic and eudaimonic facets of wellbeing, social wellbeing, the role of culture, community, nature, and governance. These additions allow for the measurement of a broader conceptualization of wellbeing, more refined and nuanced cross-cultural comparisons, and facilitate a better examination of the causes of variation in global wellbeing. The new Gallup World Poll additions will be trialled in 2020, with additional inclusions from this summit to be made in 2021

A Clinical Trial Evaluating the Usefulness of Tailored Antimicrobial Prophylaxis Using Rectal-culture Screening Media Prior to Transrectal Prostate Biopsy: A Multicenter, Randomized Controlled Trial

The aim of this report is to introduce an on-going, multicenter, randomized controlled trial to evaluate whether tailored antimicrobial prophylaxis guided by rectal culture screening prevents acute bacterial prostatitis following transrectal prostate biopsy (TRPB). Patients will be randomized into an intervention or non-intervention group; tazobactam-piperacillin or levofloxacin will be prophylactically administered according to the results of rectal culture prior to TRPB in the intervention group whereas levofloxacin will be routinely given in the non-intervention group. The primary endpoint is the occurrence rate of acute bacterial prostatitis after TRPB. Recruitment begins in April, 2021 and the target total sample size is 5,100 participants

有機地球化学的分析手法を用いた先史時代の食性復元

金沢大学先端科学・イノベーション推進機構①土器付着炭化物の炭素年代測定や安定同位体分析による食性解析法，②土器残存有機物組成や分解生成物を同定するバイオマーカー分析，③土器から抽出した炭素数16，18の直鎖状飽和脂肪酸の炭素同位体比を現生生物と直接比較することにより，起源物質を推定する手法，これら三つの手法（①，②，③）を法補的に組み合わせることにより，土器付着炭化物と土器胎土吸着物を用いて，土器で調理された食材を復元することができた。つまり，新しい縄文土器を用いた古食性研究手法を確立した。We studied radiocarbon dates and stable isotope composition in archaeological remains and lipids in pottery from a few archaeological site, Japan. These results of radiocarbon dating, stable isotope and lipid analysis are consistent with archaeological context. Therefore we have reconstructed paleodiet using Jomon pottery from a few archaeological site.研究課題/領域番号:25282072, 研究期間(年度):2013-04-01 – 2016-03-3
