Records of thrips on bamboo, take and sasa (Poaceae: Bambusoideae) in the Kyoto Botanical Garden, with a special reference to ovoviviparity in Phlaeothripinae (Insecta: Thysanoptera)
Thrips on the bamboo, take, and sasa plants in the Kyoto Botanical Garden at Shimogamo in Kyoto City were collected in May and July of 2016. A total of 9 species was collected, five species were reported here for the first time from Kyoto Prefecture, and four of them seem to have close association with various bamboo, take, and sasa plants. Several species of thrips recorded here are predators of small arthropods. We mentioned that some predaceous or omnivorous tuburiferan thrips in Phlaeothrips-lineage and Haplothrips-lineage are likely to be ovoviviparous species
Exploration of new chemical materials using black-box optimization with the D-wave quantum annealer
In materials informatics, searching for chemical materials with desired
properties is challenging due to the vastness of the chemical space. Moreover,
the high cost of evaluating properties necessitates a search with a few clues.
In practice, there is also a demand for proposing compositions that are easily
synthesizable. In the real world, such as in the exploration of chemical
materials, it is common to encounter problems targeting black-box objective
functions where formalizing the objective function in explicit form is
challenging, and the evaluation cost is high. In recent research, a Bayesian
optimization method has been proposed to formulate the quadratic unconstrained
binary optimization (QUBO) problem as a surrogate model for black-box objective
functions with discrete variables. Regarding this method, studies have been
conducted using the D-Wave quantum annealer to optimize the acquisition
function, which is based on the surrogate model and determines the next
exploration point for the black-box objective function. In this paper, we
address optimizing a black-box objective function containing discrete variables
in the context of actual chemical material exploration. In this optimization
problem, we demonstrate results obtaining parameters of the acquisition
function by sampling from a probability distribution with variance can explore
the solution space more extensively than in the case of no variance. As a
result, we found combinations of substituents in compositions with the desired
properties, which could only be discovered when we set an appropriate variance.Comment: 14pages, 4figures, 4table
CVIT expert consensus document on primary percutaneous coronary intervention (PCI) for acute myocardial infarction (AMI) in 2018
While primary percutaneous coronary intervention (PCI) has significantly contributed to improve the mortality in patients with ST segment elevation myocardial infarction even in cardiogenic shock, primary PCI is a standard of care in most of Japanese institutions. Whereas there are high numbers of available facilities providing primary PCI in Japan, there are no clear guidelines focusing on procedural aspect of the standardized care. Whilst updated guidelines for the management of acute myocardial infarction were recently published by European Society of Cardiology, the following major changes are indicated; (1) radial access and drug-eluting stent over bare metal stent were recommended as Class I indication, and (2) complete revascularization before hospital discharge (either immediate or staged) is now considered as Class IIa recommendation. Although the primary PCI is consistently recommended in recent and previous guidelines, the device lag from Europe, the frequent usage of coronary imaging modalities in Japan, and the difference in available medical therapy or mechanical support may prevent direct application of European guidelines to Japanese population. The Task Force on Primary Percutaneous Coronary Intervention of the Japanese Association of Cardiovascular Intervention and Therapeutics (CVIT) has now proposed the expert consensus document for the management of acute myocardial infarction focusing on procedural aspect of primary PCI
Anti-myeloma Activity by Thiazolidine-2,4-dione compounds
Proviral Integrations of Moloney virus 2 (PIM2) kinase is overexpressed in multiple myeloma (MM) cells, and regarded as an important therapeutic target. Here, we aimed to validate the therapeutic efficacy of different types of PIM inhibitors against MM cells for their possible clinical application. Intriguingly, the thiazolidine 2,4 dione family compounds SMI 16a and SMI 4a reduced PIM2 protein levels and impaired MM cell survival preferentially in acidic conditions, in contrast to other types of PIM inhibitors, including AZD1208, CX 6258 and PIM447. SMI 16a also suppressed the drug efflux function of breast cancer resistance protein, minimized the sizes of side populations, and reduced in vitro colony forming capacity and in vivo tumorigenic activity in MM cells, suggesting impairment of their clonogenic capacity. PIM2 is known to be subject to ubiquitination-independent proteasomal degradation. Consistently, the proteasome inhibitors bortezomib and carfilzomib increased PIM2 protein levels in MM cells without affecting its mRNA levels. However, SMI 16a mitigated the PIM2 protein increase and cooperatively enhanced anti MM effects in combination with carfilzomib. Collectively, the thiazolidine 2,4 dione family compounds SMI 16a and SMI 4a uniquely reduce PIM2 protein in MM cells, which may contribute to their profound efficacy in addition to their immediate kinase inhibition. Their combination with proteasome inhibitors is envisioned
Genetic Variants of Human Granzyme B Predict Transplant Outcomes after HLA Matched Unrelated Bone Marrow Transplantation for Myeloid Malignancies
Serine protease granzyme B plays important roles in infections, autoimmunity, transplant rejection, and antitumor immunity. A triple-mutated granzyme B variant that encodes three amino substitutions (Q48R, P88A, and Y245H) has been reported to have altered biological functions. In the polymorphism rs8192917 (2364A>G), the A and G alleles represent wild type QPY and RAH mutant variants, respectively. In this study, we analyzed the impact of granzyme B polymorphisms on transplant outcomes in recipients undergoing unrelated HLA-fully matched T-cell-replete bone marrow transplantation (BMT) through the Japan Donor Marrow Program. The granzyme B genotypes were retrospectively analyzed in a cohort of 613 pairs of recipients with hematological malignancies and their unrelated donors. In patients with myeloid malignancies consisting of acute myeloid leukemia and myelodysplastic syndrome, the donor G/G or A/G genotype was associated with improved overall survival (OS; adjusted hazard ratio [HR], 0.60; 95% confidence interval [CI], 0.41–0.89; P = 0.01) as well as transplant related mortality (TRM; adjusted HR, 0.48; 95% CI, 0.27–0.86, P = 0.01). The recipient G/G or A/G genotype was associated with a better OS (adjusted HR, 0.68; 95% CI, 0.47–0.99; P = 0.05) and a trend toward a reduced TRM (adjusted HR, 0.61; 95% CI, 0.35–1.06; P = 0.08). Granzyme B polymorphism did not have any effect on the transplant outcomes in patients with lymphoid malignancies consisting of acute lymphoid leukemia and malignant lymphoma. These data suggest that there is an association between the granzyme B genotype and better clinical outcomes in patients with myeloid malignancies after unrelated BMT
