Published: May 2023

Abstract

Background
Adverse childhood experiences (ACEs) are a risk factor for obesity; however, the causal mechanisms are not well understood. Objectives were to measure the impact of ACEs on adulthood obesity and to investigate whether the association was mediated by nutrition and stress.

Methods
A longitudinal study was conducted using adults aged 46–90 years (n = 26 615) from the Canadian Longitudinal Study on Aging. Participants were asked to recall ACEs from &lt;18 years of age. Body mass index (BMI), waist circumference and per cent body fat were measured (2015–18) and obesity was defined using standard cut points. Nutrition was measured using data from the Short Diet Questionnaire and stress was measured using allostatic load. Multinomial logistic regression was used to estimate odds ratios (ORs) and 95% CIs for each obesity measure. Causal mediation methods were used to determine whether nutrition and stress were mediators.

Results
There were 66% of adults who had experienced one or more ACE. The odds of obesity defined by BMI and waist circumference increased in a dose–response manner with increasing number of ACEs (P trend &lt;0.001). For instance, adults with four to eight ACEs, compared with none, had greater odds of obesity, defined by BMI (adjusted OR: 1.54; 95% CI: 1.28–1.75) and waist circumference (adjusted OR: 1.30; 95% CI: 1.15–1.47). There was no evidence of mediation by stress or nutrition.

Conclusions
Adversity experienced in early life is strongly associated with obesity among Canadian adults. Further research is needed to identify other mechanisms for this association to inform obesity prevention strategies.
Output feedback backstepping control for non-linear systems using an adaptive finite time sliding mode observer
Authors: Feng Jiehua , Zhao Dongya , Yan Xing-Gang , Spurgeon Sarah K 
Published: May 2023

Abstract
In this paper, a class of non-linear systems in normal form is considered, which is composed of internal and external dynamics. An adaptive finite time sliding mode observer is first designed so that the system states, unmatched uncertain parameters and matched uncertainties can all be observed in finite time. Then, the systematic backstepping design procedure is employed to develop a novel output feedback backstepping control (OFBC). The proposed OFBC method can stabilize the considered non-linear systems despite the presence of non-linear internal dynamics and unmatched uncertainties. A Lyapunov method is used to ensure that the closed-loop system is asymptotically stable. Two MATLAB simulation examples are used to demonstrate the method.

Abstract

Aims
Rotation is an effective strategy for controlling crop diseases and improving plant health. However, the effect of a mushroom-tobacco rotation on the composition and structure of microbial communities in continuous cropping soil is unclear.

Methods and results
This study analysed the structure and function of soil bacterial and fungal communities using Illumina MiSeq high-throughput 16S rRNA gene sequencing. The results showed that the physicochemical properties (organic matter, available nitrogen, available phosphorus, and available potassium) and enzymatic activity (phosphatase, catalase, urease and invertase activity) in the rotation treatments (Y1, M1, Y2 and M2) were significantly higher than those in the control (continuous cropping) treatment (CK) and reached peak values in the M2 treatment. PCA showed that the soil microbial community structure in each rotation treatment was different from that in the control. The dominant bacterial phyla of the different soil treatments were Proteobacteria and Actinobacteriota, and the dominant fungal phyla of the different soil treatments were Ascomycota and Basidiomycota. The M2 rotation significantly reduced the relative abundance of harmful fungi (Penicillium and Gibberella) compared to the other treatments. RDA showed that the most abundant bacterial taxa were negatively correlated with pH and positively correlated with physicochemical properties. However, the most abundant fungal taxa were positively correlated with pH and negatively correlated with physicochemical properties.

Conclusions
The mushroom-tobacco rotation can effectively maintain the ecological balance of the substrate microbial environment, and provide a more effective way to prevent the continuous cropping of tobacco.

Abstract
Dairy calves are highly susceptible to the negative effects of heat stress, which can cause organ hypoxia after blood redistribution, damage the intestinal barrier, and trigger intestinal oxidative stress. This study aimed to investigate the antioxidant effects of monoammonium glycyrrhizinate (MAG) on calf small intestinal epithelial cells under heat stress in vitro. Small intestinal epithelial cells were isolated from a 1-d-old healthy calf and purified by differential enzymatic detachment. The purified cells were divided into seven groups. The control group was cultured with DMEM/F-12 at 37 °C for 6 h, and the treatment groups were cultured with 0, 0.1, 0.25, 0.5, 1, or 5 μg/mL MAG at 42 °C for 6 h. Heat stress causes oxidative damage to cells. Adding MAG to the medium can significantly improve cell activity and reduce cellular oxidative stress. MAG significantly increased the total antioxidant capacity and superoxide dismutase activity caused by heat stress, and significantly decreased malondialdehyde and nitric oxide levels. The MAG treatment also reduced lactate dehydrogenase release, increased mitochondrial membrane potential, and decreased apoptosis under heat stress. MAG also upregulated the expression of the antioxidant-related genes, Nrf2 and GSTT1, in heat-stressed intestinal epithelial cells and significantly downregulated the expression of the heat shock response-related proteins, MAPK, HSP70, HSP90, and HSP27. From the above results, we conclude that 0.25 μg/mL MAG improves the capability of the antioxidant system in small intestinal epithelial cells to eliminate reactive oxygen species by activating antioxidant pathways, improving the oxidant/antioxidant balance, lowering excessive heat shock responses, and reducing intestinal oxidative stress.
Elimination of structural and tree infestations of the Asian subterranean termite, Coptotermes gestroi (Wasmann) (Blattodea: Rhinotermitidae) with noviflumuron baits in above-ground stations

Abstract
The traditional stake survey and in-ground (IG) monitoring stations have been ineffective in aggregating the Asian subterranean termite, Coptotermes gestroi (Wasmann) in southeastern Florida. In this study, we used both IG and above-ground (AG) Sentricon stations to monitor and bait C. gestroi, and as expected, none of the 83 IG stations was intercepted. Despite this, AG bait stations with 0.5% noviflumuron were successfully used to eliminate C. gestroi colonies. From 2 field experiments, the mean colony elimination time (±SD) using AG baits were 6.4 ± 3.8 wk (n = 4) and 8.0 ± 2.1 wk (n = 12), respectively. Such results were compatible with baiting studies against field colonies of C. gestroi elsewhere, that is, 4–9 wk. The successful rates in monitoring and baiting of C. gestroi with IG stations in other regions also varied, which may be due to the variabilities in tunnel geometry of this species in different environments. In areas with established C. gestroi populations, routine inspection for signs of activity in structures and surrounding trees can be a critical component for pest control providers for early detection of infestation and colony elimination with AG bait stations.

AbstractSince the early days of artificial intelligence (AI), many logics have been explored as tools for knowledge representation and reasoning. In the spirit of the Crossley Festscrift and recognizing John Crossley’s diverse interests and his legacy in both mathematical logic and computer science, I discuss examples from my own research that sit in the overlap of logic and AI, with a focus on supporting human–AI interactions.

Abstract

Background
Nivolumab and ipilimumab combination therapy is approved in Japan for unresectable or metastatic renal cell carcinoma. Because the clinical trials supporting the approval of nivolumab and ipilimumab combination therapy included relatively few Japanese patients, post-marketing surveillance was implemented to collate further safety data for nivolumab and ipilimumab combination therapy.

Methods
Patients with unresectable or metastatic renal cell carcinoma who started nivolumab and ipilimumab combination therapy between September 2018 and December 2019 were registered in this post-marketing surveillance. The observation period was 13 weeks. Safety data included treatment-related adverse events with a particular emphasis on the gastrointestinal-related (colitis, enteritis, diarrhoea and gastrointestinal perforation) and liver-related (hepatic failure, hepatic function abnormal, hepatitis and cholangitis sclerosing) treatment-related adverse events that are listed in the risk management plan for nivolumab and ipilimumab combination therapy.

Results
Of the 203 patients registered, safety data were available for 159 (119 males/40 females) with a median age of 67 years (range 22–88). Seventy-one patients received nivolumab and ipilimumab combination therapy four times per usual clinical therapy, and 33 continued nivolumab monotherapy thereafter. Any-grade treatment-related adverse events were reported in 102 (64.2%) patients and grade ≥ 3 in 63 (39.6%). Hepatic function abnormalities (13.2%), rash (8.8%) and interstitial lung disease (7.5%) were the most common treatment-related adverse events. Five patients died following treatment-related adverse events. Gastrointestinal-related and liver-related treatment-related adverse events occurred in 10 (6.3%; four with grade ≥ 3 treatment-related adverse events) and 27 (17.0%; 19 with grade ≥ 3 treatment-related adverse events) patients, respectively.

Conclusions
This post-marketing surveillance in patients with unresectable or metastatic renal cell carcinoma revealed a safety profile for nivolumab and ipilimumab combination therapy consistent with CheckMate 214. Furthermore, no new safety concerns were identified including gastrointestinal-related and liver-related treatment-related adverse events.
The various faces of vulnerability: offering neurointerventions to criminal offenders

Published: May 2023

Abstract
In recent years, we have witnessed considerable progress in neurotechnologies that visualize or alter a person’s brain and mental features. In the near future, some of these technologies could possibly be used to change neural parameters of high-risk behavior in criminal offenders, often referred to as neurointerventions. The idea of delivering neurointerventions to criminal justice populations has raised fundamental normative concerns, but some authors have argued that offering neurointerventions to convicted offenders could be permissible. However, such offers raise normative concerns too. One prominent worry that is often emphasized in the literature, relates to the vulnerability of convicted offenders in prison and forensic patients in mental health facilities. In this paper, we aim to show that as far as vulnerability is considered relevant within the context of offering medical interventions to offenders, it could contribute to arguments against as well as in favor of these offers.
Legionella pneumophila-mediated host posttranslational modifications
Authors: Yang Yi , Mei Ligang , Chen Jing , Chen Xiaorong , Wang Zhuolin , Liu Lu , Yang Aimin 
Published: May 2023

AbstractLegionella pneumophila is a Gram-negative bacterium ubiquitously present in freshwater environments and causes a serious type of pneumonia called Legionnaires’ disease. During infections, L. pneumophila releases over 300 effector proteins into host cells through an Icm/Dot type IV secretion system to manipulate the host defense system for survival within the host. Notably, certain effector proteins mediate posttranslational modifications (PTMs), serving as useful approaches exploited by L. pneumophila to modify host proteins. Some effectors catalyze the addition of host protein PTMs, while others mediate the removal of PTMs from host proteins. In this review, we summarize L. pneumophila effector-mediated PTMs of host proteins, including phosphorylation, ubiquitination, glycosylation, AMPylation, phosphocholination, methylation, and ADP-ribosylation, as well as dephosphorylation, deubiquitination, deAMPylation, deADP-ribosylation, dephosphocholination, and delipidation. We describe their molecular mechanisms and biological functions in the regulation of bacterial growth and Legionella-containing vacuole biosynthesis and in the disruption of host immune and defense machinery.
El Niño Southern Oscillation (ENSO) effects on local weather, arboviral diseases, and dynamics of managed and unmanaged populations of Aedes aegypti (Diptera: Culicidae) in Puerto Rico

Published: May 2023

Abstract
We investigated the effects of interannual El Niño Southern Oscillation (ENSO) events on local weather, Aedes aegypti populations, and combined cases of dengue (DENV), chikungunya (CHIKV), and Zika (ZIKV) viruses in 2 communities with mass mosquito trapping and 2 communities without mosquito control in southern Puerto Rico (2013–2019). Gravid adult Ae. aegypti populations were monitored weekly using Autocidal Gravid Ovitraps (AGO traps). Managing Ae. aegypti populations was done using 3 AGO traps per home in most homes. There were drought conditions in 2014–2015 concurrent with the emergence of a strong El Niño (2014–2016), wetter conditions during La Niña (2016–2018), a major hurricane (2017), and a weaker El Niño (2018–2019). The main factor explaining differences in Ae. aegypti abundance across sites was mass trapping. Populations of Ae. aegypti reached maximum seasonal values during the wetter and warmer months of the year when arbovirus epidemics occurred. El Niño was significantly associated with severe droughts that did not impact the populations of Ae. aegypti. Arbovirus cases at the municipality level were positively correlated with lagged values (5–12 mo.) of the Oceanic El Niño Index (ONI), droughts, and abundance of Ae. aegypti. The onset of strong El Niño conditions in Puerto Rico may be useful as an early warning signal for arboviral epidemics in areas where the abundance of Ae. aegypti exceeds the mosquito density threshold value.

Abstract
We investigated dose perturbations caused by 125I seeds in patients undergoing supplemental external beam radiotherapy (EBRT) for prostate cancer. We examined two types of nonradioactive seed models: model 6711 and model STM1251. All experiments were performed using a water-equivalent phantom. Radiochromic film was used to measure the dose distributions adjacent to the seeds upstream and downstream of the external beam source. Single and clusters of multiple seeds were placed in slots in a solid water (SW) slab to measure dose perturbations with separate versus dense seed placement at beam energies of 6 or 10 MV. Monte Carlo simulations (MCSs) were also performed to include the theoretical basis against film dosimetry. Distinct patterns of dose enhancement (buildup [BU]) were upstream, and dose reduction (builddown [BD]) were downstream of the radiation source. Model 6711 with lower photon beam energies produced larger dose perturbations of BU and BD than the model STM1251. The results showed the same tendency with different seed placements and beam energies. However, these differences were not observed in the rotational irradiation measurement, which replicated a clinical plan. Dose perturbations around seeds result in dose enhancement and dose reduction with varying impact depending on the photon beam energy and seed type. This has the potential to cancel out these perturbations using multiple beam direction fields.
MiR-588 acts as an oncogene in ovarian cancer and increases the radioresistance of ovarian cancer cells
Authors: Su Xiaojuan , Wang Binbin , Zhang Bo , Pan Shiwen 
Published: May 2023

Abstract
The therapeutic outcomes of ovarian cancer (OVCA) patients are majorly limited by the development of acquired chemo/radioresistance and the lack of targeted therapies. Accumulating studies demonstrate that microRNAs are involved in tumorigenesis and radioresistance. This study aims to illustrate the role of miR-588 in the radioresistance of OVCA cells. The levels of miR-588 and mRNAs were detected by reverse transcriptase quantitative polymerase chain reaction (RT-qPCR). OVCA cell viability, proliferative, migratory and invasive capacities were evaluated by the cell counting kit-8 (CCK-8) assay, colony formation assay, wound healing assay and transwell assay, respectively. The luciferase activities of plasmids containing wild -type and mutant serine/arginine-rich splicing factor 6 (SRSF6) 3'-untranslated region in miR-588 silenced OVCA cells were detected by a luciferase reporter assay. We found that miR-588 was overexpressed in OVCA tissues and cells. Knockdown of miR-588 exerted an inhibitory effect on the proliferation, migration and invasion and strengthened the radiosensitivity of OVCA cells, whereas overexpression of miR-588 increased the radioresistance of OVCA cells. SRSF6 was verified to be targeted by miR-588 in OVCA cells. In addition, the expression level of miR-588 was negatively correlated with that of SRSF6 in OVCA clinical samples. Rescue assays indicated that SRSF6 knockdown reversed the effect of miR-588 inhibition of OVCA cells under radiation. Overall, miR-588 acts as an oncogene in OVCA and increases the radioresistance of OVCA cells by targeting SRSF6.
Non-parametric inference about mean functionals of non-ignorable non-response data without identifying the joint distribution
Authors: Li Wei , Miao Wang , Tchetgen Tchetgen Eric 
Published: May 2023

Abstract
We consider identification and inference about mean functionals of observed covariates and an outcome variable subject to non-ignorable missingness. By leveraging a shadow variable, we establish a necessary and sufficient condition for identification of the mean functional even if the full data distribution is not identified. We further characterize a necessary condition for n-estimability of the mean functional. This condition naturally strengthens the identifying condition, and it requires the existence of a function as a solution to a representer equation that connects the shadow variable to the mean functional. Solutions to the representer equation may not be unique, which presents substantial challenges for non-parametric estimation, and standard theories for non-parametric sieve estimators are not applicable here. We construct a consistent estimator of the solution set and then adapt the theory of extremum estimators to find from the estimated set a consistent estimator of an appropriately chosen solution. The estimator is asymptotically normal, locally efficient and attains the semi-parametric efficiency bound under certain regularity conditions. We illustrate the proposed approach via simulations and a real data application on home pricing.
The phenomenon of autonomous endosperm in sexual and apomictic plants
Authors: Rojek Joanna , Ohad Nir 
Published: May 2023

Abstract
Endosperm is a key nutritive tissue that supports the developing embryo or seedling, and serves as a major nutritional source for human and livestock feed. In sexually-reproducing flowering plants, it generally develops after fertilization. However, autonomous endosperm (AE) formation (i.e. independent of fertilization) is also possible. Recent findings of AE loci/ genes and aberrant imprinting in native apomicts, together with a successful initiation of parthenogenesis in rice and lettuce, have enhanced our understanding of the mechanisms bridging sexual and apomictic seed formation. However, the mechanisms driving AE development are not well understood. This review presents novel aspects related to AE development in sexual and asexual plants underlying stress conditions as the primary trigger for AE. Both application of hormones to unfertilized ovules and mutations that impair epigenetic regulation lead to AE development in sexual Arabidopsis thaliana, which may point to a common pathway for both phenomena. Apomictic-like AE development under experimental conditions can take place due to auxin-dependent gene expression and/or DNA methylation.

Abstract
Acclimation to different light regimes is at the basis of survival for photosynthetic organisms, regardless of their evolutionary origin. Previous research efforts largely focused on acclimation events occurring at the level of the photosynthetic apparatus and often highlighted species-specific mechanisms. Here, we investigated the consequences of acclimation to different irradiances in Chlorella vulgaris, a green alga that is one of the most promising species for industrial application, focusing on both photosynthetic and mitochondrial activities. Moreover, proteomic analysis of cells acclimated to high light (HL) or low light (LL) allowed identification of the main targets of acclimation in terms of differentially expressed proteins. The results obtained demonstrate photosynthetic adaptation to HL versus LL that was only partially consistent with previous findings in Chlamydomonas reinhardtii, a model organism for green algae, but in many cases similar to vascular plant acclimation events. Increased mitochondrial respiration measured in HL-acclimated cells mainly relied on alternative oxidative pathway dissipating the excessive reducing power produced due to enhanced carbon flow. Finally, proteins involved in cell metabolism, intracellular transport, gene expression, and signaling—including a heliorhodopsin homolog—were identified as strongly differentially expressed in HL versus LL, suggesting their key roles in acclimation to different light regimes.
