Editorial: Carbon allocation, volume II
No full textThe foundational elements of cellular architecture and metabolism in all living organisms are woven from carbon building blocks, underscoring the pivotal role of efficient carbon allocation in the survival and growth of all organisms. For photosynthetic entities, the intricacies of maintaining carbon flux introduce additional layers of complexity. To unravel the underlying mechanisms governing carbon storage and transfer in plants, a thorough comprehension of carbon allocation regulation becomes paramount. This is key in deciphering the multifaceted impact of carbon allocation on various aspects of plant biology, such as growth, development, reproduction, defense mechanisms, yield, biomass production, and numerous other traits (Qi et al., 2019; Hartmann et al., 2020; O’Conner et al., 2021; Boatwright et al., 2022; Tanvir et al., 2022a; Tanvir et al., 2022b; Wang et al., 2023). Despite significant strides in our comprehension of plant carbon metabolism in recent decades, the regulatory mechanisms governing carbon allocation remain elusive, primarily due to the sophisticated nature of key components involved in carbon fluxes.This editorial is published as Tanvir R, Gibson SI, Wurtele ES and Li L (2023) Editorial: Carbon allocation, volume II.

Prevotella intermedia ジペプチダーゼAの基質特異性の決定と新規オートプロセシング機構
No full textPrevotella intermedia, a gram-negative anaerobic rod, is frequently observed in subgingival polymicrobial biofilm from adults with chronic periodontitis. Peptidases in periodontopathic bacteria are considered to function as etiological reagents. Pre. intermedia OMA14 cells abundantly express an unidentified cysteine peptidase specific for Arg-4-methycoumaryl-7- amide (MCA). BAU17746 (locus tag, PIOMA14_I_1238) and BAU18827 (locus tag, PIOMA14_II_0322) emerged as candidates of this peptidase from the substrate specificity and sequence similarity with C69-family Streptococcus gordonii Arg-aminopeptidase. The recombinant form of the former solely exhibited hydrolyzing activity toward Arg-MCA, and BAU17746 possesses a 26.6% amino acid identity with the C69-family Lactobacillus helveticus dipeptidase A. It was found that BAU17746 as well as L. helveticus dipeptidase A was a P1-position Arg-specific dipeptidase A, although the L. helveticus entity, a representative of the C69 family, had been reported to be specific for Leu and Phe. The fulllength form of BAU17746 was intramolecularly processed to a mature form carrying the N-terminus of Cys15. In conclusion, the marked Arg-MCA-hydrolyzing activity in Pre. intermedia was mediated by BAU17746 belonging to the C69-family dipeptidase A, in which the mature form carries an essential cysteine at the N-terminus.長崎大学学位論文 学位記番号:博(医歯薬)甲第1215号 学位授与年月日:令和2年3月19日Author: Mohammad Tanvir Sarwar, Yuko Ohara-Nemoto, Takeshi Kobayakawa, Mariko Naito and Takayuki K.

Characterization and modification of optical properties of graphene oxide and reduced graphene oxide
No full textIn this work, we focus on finding controlled methods to tune the optical properties of reduced graphene oxide (RGO) and graphene oxide (GO). This is accomplished by ozone treatment transforming RGO into GO or altering electronic properties of GO. This approach can yield drastic color (visible absorption) change and controlled increase in fluorescence intensity, optical band gap, fluorescence lifetime, and quantum yield. A reverse process: controllable quenching of this fluorescence is achieved by thermal treatment of GO. We attribute observed optical changes to the introduction/rearrangement of oxygen-containing functional groups on the graphitic platform. Following this scenario, we model the band structure of GO subject to ozone treatment via semi-empirical PM3 calculations, which, supported by our experimental data, helps in describing the origins of GO emission. This work also shows the feasibility of ozone and thermal treatments for controllable variation of GO optical properties desirable for a variety of applications in optoelectronics and biomedicine
Effects of Priming on Self-Reported COVID-19 Vaccination Intention
No full textThis study was designed to examine the effects of priming on vaccination intention. Participants were first primed with global COVID-19 data and then with specifically tailored vaccination information: “No information,” “benefit only,” “balanced benefits and risks,” or “risks only.” We hypothesized that participants in the benefit vaccine information group, (n = 16) and the balanced vaccine information group (n = 16) would show increased intention to receive the COVID-19 vaccine compared to the vaccine risk information group (n = 17) and the control, no vaccine information group (n = 16). Further, that the risk information group would have a decreased intention to receive the vaccine compared with the control group. A general COVID-19 knowledge and experience survey was completed after presentation of the vaccination information and vaccination intention measure. The results from the one-way ANOVA did not show any statistically significant differences (p = .136). However, a medium effect size was detected (η2 = .08). Tukey’s test results show no statistically significant differences between the groups. Medium effects sizes were detected which may indicate that something was happening between the groups, but our study did not have enough power to detect it
Societal impacts and vulnerability to floods in Bangladesh and Nepal
No full textAbstractBangladesh and Nepal lie between the Himalayas and low-lying coasts of the Bay of Bengal and are traversed by hundreds of rivers and tributaries. Historical data shows that, since 1970, the scale, intensity and duration of floods have increased in Bangladesh and Nepal, causing grave human suffering; disruptions in normal life and activity, damages of infrastructure, crops and agricultural land with severe impacts on the economy. Bangladesh is affected by torrential rain, glacier melt, upstream water flow and tidal surges. In 1988, Bangladesh experienced one of the most severe floods of the twentieth century which aroused significant concern internationally and triggered the Bangladesh Action Plan for Flood Control. The Government of Bangladesh (GOB) has so far constructed a number of flood shelters and carried out 482 water and flood control projects involving flood protection embankments, drainage channels, sluice gates and regulators on different rivers and canals. These also provided safety measures against inundation by tidal waves, storm-surges and flooding. The Terai region of Nepal is highly prone to hydrological risks including torrential rain, floods, glaciers resulting in erosion and landslides. The Government of Nepal (GON) has implemented different mitigation measures mainly early warning awareness, rescue measure, relief, and post-flood rehabilitation programs etc. Disaster Management Bureaus of both the countries have already conducted many trainings, workshops and seminars to disseminate scientific knowledge and coping up practices to disaster managers and to create public awareness. Besides the contemporary approaches to mitigating flood effects, people of these countries have coped with floods through generations relying on traditional/indigenous knowledge and other local adaptation practices. It is crucial that along with scientific process, indigenous, traditional and conventional practices are to be integrated for a national and regional policy and this should be achieved through a participatory process that engages policy makers and relevant stakeholders. This paper has analyzed the vulnerability to floods, impacts and the coping strategies in Bangladesh and Nepal and focused on recommending a long-term mitigation policy
Measurement Error of Cardiac Output Determined by Nitrous Oxide Rebreathing and Impedance Cardiography in Healthy Adults
No full textCardiac output (Q̇) is a fundamental physiological variable but remains challenging to measure. Exercise Q̇ is commonly measured by inert gas rebreathing using acetylene or nitrous oxide (Q̇N2O-IGR) and impedance cardiography (Q̇IC), but device measurement error has not been assessed at different workloads, or in females. This study determined the precision of Q̇N2O-IGR (Innocor, COSMED Inc., USA) and Q̇IC (Physioflow Enduro, Manatec Biomedical, France) in duplicate in sixty adults (30 females; 22±5 years; V̇O2max: 41.2±8.6 mL.kg-1.min-1) during upright rest and cycling at 50W and 90% peak power output (PPO) (277±71W). Measurement variance was higher for Q̇N2O-IGR vs. Q̇IC (pThe presentation of the authors' names and (or) special characters in the title of the pdf file of the accepted manuscript may differ slightly from what is displayed on the item page.

Testing the randomness in the sky-distribution of gamma-ray bursts
No full textWe have studied the complete randomness of the angular distribution of gamma-ray bursts (GRBs) detected by the Burst and Transient Source Experiment (BATSE). Because GRBs seem to be a mixture of objects of different physical nature, we divided the BATSE sample into five subsamples (short1, short2, intermediate, long1, long2) based on their durations and peak fluxes, and we studied the angular distributions separately. We used three methods, Voronoi tesselation, minimal spanning tree and multifractal spectra, to search for non-randomness in the subsamples. To investigate the eventual non-randomness in the subsamples, we defined 13 test variables (nine from the Voronoi tesselation, three from the minimal spanning tree and one from the multifractal spectrum). Assuming that the point patterns obtained from the BATSE subsamples are fully random, we made Monte Carlo simulations taking into account the BATSE's sky-exposure function. The Monte Carlo simulations enabled us to test the null hypothesis (i.e. that the angular distributions are fully random). We tested the randomness using a binomial test and by introducing squared Euclidean distances in the parameter space of the test variables. We concluded that the short1 and short2 groups deviate significantly (99.90 and 99.98 per cent, respectively) from the full randomness in the distribution of the squared Euclidean distances; however, this is not the case for the long samples. For the intermediate group, the squared Euclidean distances also give a significant deviation (98.51 per cent)
