Cross-Modal Facilitation of Episodic Memory by Sequential Action Execution

Throughout our lives, the actions we produce are often highly familiar and repetitive (e.g., commuting to work). However, layered upon these routine actions are novel, episodic experiences. Substantial research has shown that prior knowledge can facilitate learning of conceptually related new information. But despite the central role our behavior plays in real-world experience, it remains unclear how engagement in a familiar sequence of actions influences memory for unrelated, nonmotor information coincident with those actions. To investigate this, we had healthy young adults encode novel items while simultaneously following a sequence of actions (key presses) that was either predictable and well-learned or random. Across three experiments (N = 80 each), we found that temporal order memory, but not item memory, was significantly enhanced for novel items encoded while participants executed predictable compared with random action sequences. These results suggest that engaging in familiar behaviors during novel learning scaffolds within-event temporal memory, an essential feature of episodic experiences.
Engagement in an mHealth-Guided Exercise Therapy Program Is Associated With Reductions in Chronic Musculoskeletal Pain

Users of an exercise therapy app reported reductions of pain and increases in quality of life and work per exercise session completed. These findings serve as preliminary understandings for the potential of mHeath exercise interventions to be deployed at scale to address current barriers to access to guided exercise therapy. Context Chronic musculoskeletal pain costs the US $980 billion annually. Conservative treatments are the criterion standard, but scalable methods of treatment remain to be evaluated. Objective The aim of the study is to determine the effects of pain reduction and the perceived benefits of an mHealth exercise therapy program. Design This is a retrospective observational study on data from 3109 people (18–98, 49% female) with musculoskeletal pain in an mHealth exercise program. Presession pain was measured via 11-point numeric rating scale and nonstandardized single-item questions for work and quality of life; all were analyzed using mixed-effects models. Results By 11 sessions, there was an estimated a 2.09-point decrease in average numeric rating scale pain levels. There was an average percent increase of approximately 0.7 points for work life and quality of life (tdf=6,632 = 12.06, P < 0.001). User engagement was high; 46% of participants were performing more than one session per day, and 88% were engaging within a week, indicating the feasibility of the deployment of an mHealth exercise app. Conclusions An mHealth exercise program was associated with significant decrease in pain and increased perceived benefits in a large population. These findings serve as preliminary findings of the feasibility for mHealth exercise interventions as scalable tools to improve chronic musculoskeletal pain outcomes.
Biological activity of a chitosan-carboxymethylcellulose-zinc oxide and calcium carbonate in 3D scaffolds stabilized by physical links for bone tissue engineering

Today, regenerative osteogenesis represents a clinical need, due to the incidence of bone defects that involve groups of pathologies ranging from congenital anomalies to traumatic injuries, as well as problems presented surgically. This is why the design of a polymeric biomaterial (scaffold) of chitosan, carboxymethylcellulose, zinc oxide, and calcium carbonate with similar characteristics in terms of composition and bone structure offers high potential to help address this health problem. The technique for obtaining the scaffolds of this research was to develop a physical hydrogel to have the biofunctionality of the active groups of the polymer chains used, then make use of the lyophilization process to obtain three-dimensional (3D) porous scaffolds. The physicochemical and biological properties of the scaffolds were evaluated. The scaffolds presented morphology with pore size and interconnectivity that favor the need for cell proliferation and viability. The biocompatibility tests confirm that the designed scaffolds do not present cytotoxicity and the analyzes with alizarin red staining show calcium deposits in the materials with CaCO3 and ZnO. Osteoinduction assays to osteogenic lineage using runt-related transcription factor type 2 (RUNX2) and collagen type 1 (COL-1) antibodies allowed expression in differentiated cells. Therefore, the calcium carbonate-containing scaffolds stabilized by physical bonds have characteristics of being non-cytotoxic, bioactive, and osteoinductive, which motivate their use in future tests to evaluate their demeanor with rat models for bone engineering studies.

High-Resolution Magnetic Resonance Imaging in Endovascular Treatment of Vertebrobasilar Junction Stenosis

Introduction: Vertebrobasilar junction (VBJ) stenosis is a challenge in endovascular treatment due to structural variants and complexities. The role of high-resolution magnetic resonance imaging (HRMRI) in endovascular treatment for patients with severe VBJ stenosis is uncertain. Case Report: Four patients with symptomatic VBJ stenosis underwent HRMRI of the vessel wall before endovascular treatment. In 3 patients, the VBJ could not be visualized on luminal imaging. One of them had a hypoplastic artery and 2 of them had severe stenotic arteries on HRMRI. HRMRI showed an artery with a negative remodeling in a patient with a hypoplastic vertebral artery. One patient had intraplaque hemorrhage and calcification, and 2 patients had calcification in VBJ lesions. Endovascular treatment was performed utilizing HRMRI findings to guide the decision-making process. Conclusion: HRMRI provides additional information about the structure and angle of the VBJ, the characteristics and vulnerability of the plaques, and the lesion size, thus helping to improve the operation process and reduce the risk of complications.
Phytoplankton life strategies, phenological shifts and climate change in the North Atlantic Ocean from 1850 to 2100

Significant phenological shifts induced by climate change are projected within the phytoplankton community. However, projections from current Earth System Models (ESMs) understandably rely on simplified community responses that do not consider evolutionary strategies manifested as various phenotypes and trait groups. Here, we use a species‐based modelling approach, combined with large‐scale plankton observations, to investigate past, contemporary and future phenological shifts in diatoms (grouped by their morphological traits) and dinoflagellates in three key areas of the North Atlantic Ocean (North Sea, North‐East Atlantic and Labrador Sea) from 1850 to 2100. Our study reveals that the three phytoplanktonic groups exhibit coherent and different shifts in phenology and abundance throughout the North Atlantic Ocean. The seasonal duration of large flattened (i.e. oblate) diatoms is predicted to shrink and their abundance to decline, whereas the phenology of slow‐sinking elongated (i.e. prolate) diatoms and of dinoflagellates is expected to expand and their abundance to rise, which may alter carbon export in this important sink region. The increase in prolates and dinoflagellates, two groups currently not considered in ESMs, may alleviate the negative influence of global climate change on oblates, which are responsible of massive peaks of biomass and carbon export in spring. We suggest that including prolates and dinoflagellates in models may improve our understanding of the influence of global climate change on the biological carbon cycle in the oceans.
Determination of lower radiation dose limit for automatic measurement of adipose tissue

Abstract The purpose of this study was to determine the lower limit of radiation dose required to measure visceral adipose tissue (VAT) and subcutaneous adipose tissue (SAT) volumes when a fat quantification and noise reduction techniques (NRTs) are combined. For this purpose, we utilized CT colonography (CTC) images taken at low doses and manually segmented VAT and SAT fat volumes as ground truth. In order to derive the acceptable precision of the measurements needed to estimate the lower limit of radiation dose, we estimated the effect of different positioning during CT scanning on fat measurements using manually segmented VAT and SAT against normal dose. As a result, the acceptable accuracy of SAT and VAT was found to be 94.5% and 85.2%, respectively. Using these thresholds, the lower radiation dose limit required to accurately measure SAT using 5.25‐mm slice‐thick images was 1.5 mGy of size‐specific dose estimates (SSDE), while the lower radiation dose limit required to accurately measure VAT was 0.4 mGy of SSDE. The lower dose limit for SAT and VAT combined was 1.5 mGy, which was equivalent to an estimated effective dose of 0.38 mSv. Alternatively, without noise reduction, SAT could not achieve acceptable accuracy even for images with a slice thickness of 5.25 mm, while VAT required noise reduction for images with a slice thickness of 1.25 mm, but could achieve acceptable accuracy without noise reduction for images with a slice thickness of 5.25 mm.
Three Aedes species infested by mermithids in France

Mermithid nematodes (Nematoda, Mermithidae) parasitising mosquitoes could be useful as biological agents for the control of host populations. Nine female mosquitoes belonging to the species Aedes cantans, Ae. communis, and Ae. rusticus were found parasitised by mermithids in Northern France. Sequencing of partial 18S rDNA showed 100% sequence homology for all processed specimens. The mermithid sequences were closely related to specimens previously recorded from Anopheles gambiae in Senegal. However, 18S sequences do not allow for identification of nematodes at the genus or species level. Our specimens could also be related to Strelkovimermis spiculatus, or belong to other genera not yet sequenced such as Empidomermis, the only mermithid genus recorded from mosquitoes in France.
Three‐dimensional lab‐on‐a‐foil device for dielectrophoretic separation of cancer cells

A simple, low‐cost, three‐dimensional (3D) lab‐on‐a‐foil microfluidic device for dielectrophoretic separation of circulating tumor cells (CTCs) is designed and constructed. Disposable thin films are cut by xurography and microelectrode array are made with rapid inkjet printing. The multilayer device design allows the studying of spatial movements of CTCs and red blood cells (RBCs) under dielectrophoresis (DEP). A numerical simulation was performed to find the optimum driving frequency of RBCs and the crossover frequency for CTCs. At the optimum frequency, RBCs were lifted 120 µm in z‐axis direction by DEP force, and CTCs were not affected due to negligible DEP force. By utilizing the displacement difference, the separation of CTCs (modeled with A549 lung carcinoma cells) from RBCs in z‐axis direction was achieved. With the nonuniform electric field at optimized driving frequency, the RBCs were trapped in the cavities above the microchannel, whereas the A549 cells were separated with a high capture rate of 86.3% ± 0.2%. The device opens not only the possibility for 3D high‐throughput cell separation but also for future developments in 3D cell manipulation through rapid and low‐cost fabrication.
Cure of Disseminated Human Lymphoma with [225Ac]Ac-Ofatumumab in a Preclinical Model

Visual Abstract Immunotherapies that target the CD20 protein expressed on most non-Hodgkin lymphoma cells have improved clinical outcomes, but relapse is common. We prepared 225Ac-labeled anti-CD20 ofatumumab and evaluated its in vitro characteristics and therapeutic efficacy in a murine model of disseminated human lymphoma. Methods: 225Ac was chelated by DOTA-ofatumumab, and radiochemical yield, purity, immunoreactivity, stability, and chelate number were determined. In vitro cell killing of CD20-positive, human B-cell lymphoma Raji-Luc cells was assayed. Biodistribution was determined as percentage injected activity per gram (%IA/g) in mice with subcutaneous Raji-cell tumors (n = 4). [225Ac]Ac-ofatumumab biodistribution in C57BL/6N mice was performed to estimate projected human dosimetry. Therapeutic efficacy was tested in mice with systemically disseminated Raji-Luc cells, tracking survival, bioluminescence, and animal weight for a targeted 200 d, with single-dose therapy initiated 8, 12, or 16 d after cell injection, comparing no treatment, ofatumumab, and low (3.7 kBq/mouse) and high (9.25 kBq/mouse) doses of [225Ac]Ac-IgG and [225Ac]Ac-ofatumumab (n = 8–10/cohort). Results: Radiochemical yield and purity were 32% ± 9% and more than 95%, respectively. Specific activity was more than 5 MBq/mg. Immunoreactivity was preserved, and more than 90% of the 225Ac remained chelated after 10 d in serum. Raji-Luc cell killing in vitro was significant, specific, and dose-dependent. In tumor-bearing mice, [225Ac]Ac-ofatumumab displayed low liver (7 %IA/g) and high tumor (28 %IA/g) uptake. Dosimetry estimates indicated that bone marrow is likely the dose-limiting organ. When therapy was initiated 8 d after cell injection, untreated mice and mice treated with cold ofatumumab or low- or high-dose [225Ac]Ac-IgG showed indistinguishable median survivals of 20–24 d, with extensive cancer-cell burden before death. Low- and high-dose [225Ac]Ac-ofatumumab profoundly (P < 0.05) extended median survival to 190 d and more than 200 d (median not determinable), with 5 and 9 of 10 mice, respectively, surviving at study termination with no detectable cancer cells. Surviving mice treated with high-dose [225Ac]Ac-ofatumumab showed reduced weight gain versus naïve mice. When therapy was initiated 12 d, but not 16 d, after cell injection, high-dose [225Ac]Ac-ofatumumab significantly extended median survival to 40 d but was not curative. Conclusion: In an aggressive disseminated tumor model, [225Ac]Ac-ofatumumab was effective at cancer-cell killing and curative when administered 8 d after cell injection. [225Ac]Ac-ofatumumab has substantial potential for clinical translation as a next-generation therapeutic for treatment of patients with non-Hodgkin lymphoma.
The language of vaccination campaigns during COVID-19

Understanding what makes communication effective when designing public health messages is of key importance. This applies in particular to vaccination campaigns, which aim to encourage vaccine uptake and respond to vaccine hesitancy and dispel any myth or misinformation. This paper explores the ways in which the governments of Great Britain (England, Scotland and Wales) promoted COVID-19 vaccination as a first-line strategy and studies health message effectiveness by examining the language of official vaccination campaigns, vaccine uptake across the different nations and the health message preferences of unvaccinated and vaccine sceptic individuals. The study considers communications beginning at the first lockdown until the point when daily COVID-19 updates ended for each nation. A corpus linguistic analysis of official government COVID-19 updates is combined with a qualitative examination of the expression of evaluation in governmental discourses, feedback from a Public Involvement Panel and insights from a nationally representative survey of adults in Great Britain to explore message production and reception. Fully vaccinated, unvaccinated and sceptic respondents showed similar health messaging preferences and perceptions of health communication efficacy, but unvaccinated and sceptic participants reported lower levels of compliance for all health messages considered. These results suggest that issues in health communication are not limited to vaccination hesitancy, and that in the future, successful vaccination campaigns need to address the determining factors of public attitudes and beliefs besides communication strategies.
Gastric schwannoma coexisting with tubular adenoma of the gallbladder: a rare combination

We report a case of a man in his early 50 s who was admitted to our hospital for anorexia. An imaging examination led to a preoperative diagnosis of a gastrointestinal stromal tumor and gallbladder stones. He underwent treatment by laparoscopic cholecystectomy and distal partial gastrectomy with lymph node dissection. The final histopathological diagnosis was gastric schwannoma and tubular adenoma of the gallbladder. Gastric schwannoma accounts for only 0.2% of all gastric tumors, and tubular adenoma constitutes only 2.2% of gallbladder tumors. This report describes the diagnosis and treatment process for this combination of tumors, thus providing a reference for similar cases.
ACCRETION MECHANISMS ONTO PRIMORDIAL BLACK HOLES

We study the evolution of a primordial black hole (PBH) taking into account the presence of dark energy modeled by a general perfect fluid. In the specific case of a stationary non-self-gravitating test fluid, the competition between radiation accretion, Hawking evaporation and the accretion of such a fluid has been studied in detail. The evaporation of PBHs is quite modified at late times by these effects. We address further generalizations of this scenario to consider other types of fluids, and point out early developments of a nonstationary accretion model.
Bacteremia caused by Aeromonas species in patients with cancer: Clinical manifestations and outcomes.

INTRODUCTION Oncologic patients can have severe infections due to Aeromonas. This study aims to investigate the clinical characteristics and outcomes of cancer patients with bloodstream infections (BSI) caused by Aeromonas. METHODOLOGY We included patients with bacteremia caused by Aeromonas species from 2011 to 2018. RESULTS Seventy-five BSI events in the same number of patients were identified. Forty patients were men (53.3%); the mean age was 49 years (IQR 28-61). A. caviae was the most frequent isolate (n = 29, 38.6%), followed by A. hydrophila (n = 23, 30.6%), A. sobria (n = 15, 20%), and A. veronii (n = 8, 10.6%). The most frequent underlying diagnosis was hematologic malignancy (n = 33, 44%), followed by breast cancer (n = 12, 16%) and gastrointestinal tract cancer (n = 8, 10.6%). The most frequent type of bacteremia was CRBSI in 32 cases (42.6%), followed by mucosal barrier injury-laboratory confirmed BSI (n = 20, 26.7%). Sixteen (26.2%) were hospital-acquired BSI. Attributable mortality occurred in 11 patients (14.6%). In univariate analysis A. hydrophila bacteremia, liver failure, skin/soft tissue infection, septic shock, inappropriate antimicrobial treatment, and relapse or cancer progression were associated with 30-day mortality. In multivariate analysis, only septic shock, inappropriate antimicrobial treatment, and relapse or cancer progression were associated with 30-day mortality. CONCLUSIONS Aeromonas species should be considered one of the causative pathogens of healthcare-associated bacteremia, especially in immunocompromised patients. In addition, it can be associated with high fatality, particularly in patients with severe clinical infections.
Experimental study on the effect of luteolin on the proliferation, apoptosis and expression of inflammation-related mediators in lipopolysaccharide-induced keratinocytes

Objective This study aimed at exploring the effects of luteolin on psoriasis-like cell model proliferation, apoptosis regulation and the expression of inflammation-related mediators. Methods A Cell Counting Kit-8 (CCK-8) assay was used to determine the survival rate of human immortalized keratinocytes (HaCaT cells) and normal human epidermal keratinocytes (NHEK cells) following stimulation with luteolin and lipopolysaccharide (LPS). Western blot and reverse transcription-quantitative polymerase chain reaction (RT-qPCR) analysis were used to detect the protein and mRNA expressions of nuclear factor (NF)-κB p65 and interleukin (IL)-6 after LPS stimulation. Then a luteolin stimulation protocol (10 μmol/L, 24 h) was determined and a reasonable LPS stimulation concentration (20 μg/mL, 24 h) was chosen to establish the psoriasis cell model. Keratinocytes in luteolin pre-treatment and control groups were stimulated with 20 μg/mL LPS for 24 h, and the expressions of NF-κB p65 and IL-6 were detected by western blot and RT-qPCR. The apoptosis of HaCaT cells was detected by flow cytometry, and the enzyme-linked immunosorbent assay (ELISA) was used to detect the expression of psoriasis-related inflammatory factors. Results CCK-8 assay indicated that luteolin inhibited the proliferation of keratinocytes. LPS stimulated the proliferation of keratinocytes and upregulated the expression of NF-κB p65 and IL-6 in a concentration-dependent manner, and induced psoriasis-like changes. Furthermore, the protein and mRNA expression levels of NF-κB p65 and IL-6 were decreased in the luteolin pre-stimulation group (p < 0.05). Treatment with luteolin downregulated the expression of the LPS-induced inflammatory mediators in keratinocytes (p < 0.05). The flow cytometry results showed that luteolin induced HaCaT cells apoptosis. Finally, ELISA results demonstrated that luteolin inhibited the release of the IL-17, IL-23 and tumor necrosis factor α (TNF-α) in the pre-stimulation group (p < 0.05). Conclusion This study confirmed that luteolin can effectively relieve inflammatory mediators in LPS-induced keratinocyte models of psoriasis, which suggested the potential of luteolin in treating psoriasis.
Surface plasmon enhanced cell microscopy with blocked random spatial activation

We present surface plasmon enhanced fluorescence microscopy with random spatial sampling using patterned block of silver nanoislands. Rigorous coupled wave analysis was performed to confirm near-field localization on nanoislands. Random nanoislands were fabricated in silver by temperature annealing. By analyzing random near-field distribution, average size of localized fields was found to be on the order of 135 nm. Randomly localized near-fields were used to spatially sample F-actin of J774 cells (mouse macrophage cell-line). Image deconvolution algorithm based on linear imaging theory was established for stochastic estimation of fluorescent molecular distribution. The alignment between near-field distribution and raw image was performed by the patterned block. The achieved resolution is dependent upon factors including the size of localized fields and estimated to be 100-150 nm.
