Predicting seasonal movements and distribution of the sperm whale using machine learning algorithms

Abstract Implementation of effective conservation planning relies on a robust understanding of the spatiotemporal distribution of the target species. In the marine realm, this is even more challenging for species rarely seen at the sea surface due to their extreme diving behavior like the sperm whales. Our study aims at (a) investigating the seasonal movements, (b) predicting the potential distribution, and (c) assessing the diel vertical behavior of this species in the Mascarene Archipelago in the south‐west Indian Ocean. Using 21 satellite tracks of sperm whales and eight environmental predictors, 14 supervised machine learning algorithms were tested and compared to predict the whales' potential distribution during the wet and dry season, separately. Fourteen of the whales remained in close proximity to Mauritius, while a migratory pattern was evidenced with a synchronized departure for eight females that headed towards Rodrigues Island. The best performing algorithm was the random forest, showing a strong affinity of the whales for sea surface height during the wet season and for bottom temperature during the dry season. A more dispersed distribution was predicted during the wet season, whereas a more restricted distribution to Mauritius and Reunion waters was found during the dry season, probably related to the breeding period. A diel pattern was observed in the diving behavior, likely following the vertical migration of squids. The results of our study fill a knowledge gap regarding seasonal movements and habitat affinities of this vulnerable species, for which a regional IUCN assessment is still missing in the Indian Ocean. Our findings also confirm the great potential of machine learning algorithms in conservation planning and provide highly reproductible tools to support dynamic ocean management.
How strong is the evidence that it is possible to get SARS‐CoV‐2 twice? A systematic review

With a large number of coronavirus disease 2019 (Covid‐19) patients being discharged from hospital with negative test results for SARS‐CoV‐2, it has been reported that several recovered cases tested positive after discharge (re‐positive, RP). This finding has raised several important questions for this novel coronavirus and Covid‐19 disease. In this review, we have discussed several important questions, including: (1) Can the virus re‐infect recovered individuals? (2) What are the possible causes of the re‐positive reverse transcriptase‐polymerase chain reaction (RT‐PCR) test in recovered patients? (3) What are the implications of these re‐positive cases concerning the spread of the virus? Understanding how recovery from Covid‐19 confers immunity to decrease the risk of re‐infection is needed to inform current efforts to safely scale back population‐based interventions, such as physical distancing. We have also described what is currently known about the immune response to Covid‐19, highlighted key gaps in knowledge, and identified opportunities for future research. Overall, the quality of the evidence is poor and we describe the features that should be described for future cases.
From breast cancer surgery to survivorship: Insecure attachment tendencies predict negative psychological outcomes

Little is known about the variables explaining individual variability in the long-term adaptation of breast cancer survivors. Attachment tendencies have, however, been shown to explain negative psychological outcomes in the postsurgical period. The present study aimed to assess the continuing influence of attachment tendencies in the survivorship period. A sample of 28 women were surveyed 2 weeks, 3 months, 12 months, and 5 to 7 years after surgery. Attachment tendencies and psychological outcomes (distress, body image, sexuality) were assessed through questionnaires, and medical and sociodemographic data collected. Results show that insecure attachment tendencies predict negative body image and elevated distress.

Depression and its associated factors among pregnant women in central Vietnam

To date, little attention has been given to prenatal depression, especially in low and middle-income countries. The aim of this research was to assess the prevalence of depression and its associated factors amongst pregnant women in a central Vietnamese city. This cross-sectional study included 150 pregnant women from 29 to 40 weeks of gestation, from eight wards of Hue city, via quota sampling from February to May 2019. We employed the Patient Health Questionnaire (PHQ-9) to assess depression. Findings suggest the need to provide routine screening of pregnant women in primary care for depressive symptoms and other mental health problems.
Coexistence of Small Threshold Voltage Instability and High Channel Mobility in 4H-SiC(0001) Metal–Oxide–Semiconductor Field-Effect Transistors

The instability in the electrical properties of 4H-SiC(0001) C-face metal–oxide–semiconductor (MOS) systems processed by wet gate oxidation with H2 postoxidation annealing (POA) was characterized. Wet-oxidized 4H-SiC C-face MOS capacitors indicated a large flat-band voltage (Vfb) shift owing to gate-bias stressing, but a H2 POA process improved the Vfb shift significantly. The threshold voltage (Vth) shift of wet-oxidized 4H-SiC C-face MOS field-effect transistors was reduced greatly to one-tenth by using an appropriate H2 POA process. These samples also indicated a high channel mobility (µfe) of 70 cm2/(V·s). The coexistence of small Vth instability and high µfe was achieved.
Long‐term dynamics of a cladoceran community from an early stage of lake formation in Lake Fukami‐ike, Japan

Abstract An increase in nutrient levels due to eutrophication has considerable effects on lake ecosystems. Cladocerans are intermediate consumers in lake ecosystems; thus, they are influenced by both the bottom‐up and top‐down effects that occur as eutrophication progresses. The long‐term community succession of cladocerans and the effects cladocerans experience through the various eutrophication stages have rarely been investigated from the perspective of the early‐stage cladoceran community assemblage during lake formation. In our research, long‐term cladoceran community succession was examined via paleolimnological analysis in the currently eutrophic Lake Fukami‐ike, Japan. We measured the concentration of total phosphorus and phytoplankton pigments and counted cladoceran and other invertebrate subfossils in all layers of collected sediment cores, and then assessed changes in the factors controlling the cladoceran community over a 354‐year period from lake formation to the present. The cladoceran community consisted only of benthic taxa at the time of lake formation. When rapid eutrophication occurred and phytoplankton increased, the benthic community was replaced by a pelagic community. After further eutrophication, large Daphnia and high‐order consumers became established. The statistical analysis suggested that bottom‐up effects mainly controlled the cladoceran community in the lake's early stages, and the importance of top‐down effects increased after eutrophication occurred. Total phosphorus and phytoplankton pigments had positive effects on pelagic Bosmina, leading to the replacement of the benthic cladoceran community by the pelagic one. In contrast, the taxa established posteutrophication were affected more by predators than by nutrient levels. A decrease in planktivorous fish possibly allowed large Daphnia to establish, and the subsequent increase in planktivorous fish reduced the body size of the cladoceran community.
Electrochemical determination of T2 toxin by graphite/polyacrylonitrile nanofiber electrode

Abstract Fabricating graphite electrode corrected with nanofiber by electrospinning as a considerable procedure for utilization in the fluid materials, milk, and syrup for detection of T2 mycotoxin is a significant technique. The modern biosensor was fabricated at normal degrees of room and utilized via buffer Britton–Robinson (B‐R) in pH = 5 to refine the chemico‐mechanical specifications. The electrochemical manner of the modified surface was surveyed using the scanning electron microscopy (SEM), cyclic voltammetry (CV), square wave voltammetry (SQWV), electrochemical impedance spectroscopy (EIS), and differential pulse voltammetry (DPV). The corrected electrode displayed a linear reply to T2 toxin in two distinct concentration ranges of 30–100 nM with correlation coefficients of 0.99. The greatest signals in the square wave spectrums for the B‐R buffer created on the uttermost signals of the obtained streams were pH = 5 and 0.5 M of KNO3 for T2 toxin. The modified electrode has a big signal, broad dynamic concentration and high sensitivity and selectivity.
Hypolipidemic, anti‐inflammatory, and anti‐atherosclerotic effects of tea before and after microbial fermentation

Abstract Background Microbial fermentation significantly affects the flavor and efficacy of tea. It is generally believed that fermented tea is more effective in lowering lipids, while unfermented tea can more effectively inhibit inflammation. However, there is not sufficient evidence to support this claim. To systematically compare the hypolipidemic, anti‐inflammatory, and anti‐atherosclerotic effects of tea before and after microbial fermentation, hyperlipidemic rats and inflammatory injury cells were treated with Monascus purpureus‐fermented pu‐erh tea water extract (MPT) and sun‐dried green tea water extract (SGT), respectively. Results MPT, with higher levels of theabrownins, flavonoids, gallic acid (GA), and lovastatin, was more effective in reducing serum triglyceride (TG), total cholesterol (TC), low‐density lipoprotein cholesterol (LDL‐C), and inflammatory cytokines (TNF‐α, IL‐1β, and IL‐6), while SGT, with higher levels of tea polyphenols, amino acids, (‐)‐epigallocatechin gallate (EGCG), and theaflavins, was more effective in increasing serum high‐density lipoprotein cholesterol (HDL‐C) in hyperlipidemic rats. The foam cells on the arterial wall of the rats in the MPT group were visibly less, and the thrombosis time was longer than that in the SGT group. Cell experiments showed that MPT was more effective in protecting endothelial cells from damage than SGT. Conclusion Surprisingly, Monascus purpureus‐fermented pu‐erh tea not only had better hypolipidemic and anti‐atherosclerotic effects than its raw material (sun‐dried green tea), but also was superior in anti‐inflammatory effects to the latter, which was possibly attributable to the great changes in functional ingredients during microbial fermentation.

Development and Validation of Three Regional Microsimulation Models for Predicting Colorectal Cancer Screening Benefits in Europe

Background. Validated microsimulation models have been shown to be useful tools in providing support for colorectal cancer (CRC) screening decisions. Aiming to assist European countries in reducing CRC mortality, we developed and validated three regional models for evaluating CRC screening in Europe. Methods. Microsimulation Screening Analysis–Colon (MISCAN-Colon) model versions for Italy, Slovenia, and Finland were quantified using data from different national institutions. These models were validated against the best available evidence for the effectiveness of screening from their region (when available): the Screening for COlon REctum (SCORE) trial and the Florentine fecal immunochemical test (FIT) screening study for Italy; the Norwegian Colorectal Cancer Prevention (NORCCAP) trial and the guaiac fecal occult blood test (gFOBT) Finnish population-based study for Finland. When published evidence was not available (Slovenia), the model was validated using cancer registry data. Results. Our three models reproduced age-specific CRC incidence rates and stage distributions in the prescreening period. Moreover, the Italian and Finnish models replicated CRC mortality reductions (reasonably) well against the best available evidence. CRC mortality reductions were predicted slightly larger than those observed (except for the Florentine FIT study), but consistently within the corresponding 95% confidence intervals. Conclusions. Our findings corroborate the MISCAN-Colon reliability in supporting decision making on CRC screening. Furthermore, our study provides the model structure for an additional tool (EU-TOPIA CRC evaluation tool: http://miscan.eu-topia.org) that aims to help policymakers and researchers monitoring or improving CRC screening in Europe.
Household finances, financial planning, and COVID‐19

Abstract This article provides a brief summary and review of the impact of the COVID‐19 pandemic on household finances. The stressors related to the pandemic are evaluated as either transitory or permanent shocks to both the practice of financial planning and client financial concerns. Based on qualitative responses from practicing financial planners, changes in practice and client concerns as a result of the pandemic are outlined. At the global level, respondents shared that the practice of financial planning has accelerated its adoption of communication technology while clients are experiencing unprecedented levels of stress related to changes in health, the economy, and the political landscape in the United States. Insights and observations from the sample of practicing financial planners are used to inform recommendations for practice.
Current Endovascular Treatment Options in Acute Pulmonary Embolism

Acute pulmonary embolism (PE) is a significant cause of mortality and morbidity across the globe. Over the last few decades, there have been major therapeutic advances in acute PE management, including catheter-based therapy. However, the effectiveness of catheter-based therapy in acute PE is not supported by Level I evidence, making the use of this promising treatment rather controversial and ambiguous. In this paper, we discuss the risk stratification of acute PE and review the medical and endovascular treatment options. We also summarize and review the data supporting the use of endovascular treatment options in acute PE and describe the potential role of the PE response team.
Bringing function to structure: Root–soil interactions shaping phosphatase activity throughout a soil profile in Puerto Rico

Abstract Large areas of highly productive tropical forests occur on weathered soils with low concentrations of available phosphorus (P). In such forests, root and microbial production of acid phosphatase enzymes capable of mineralizing organic phosphorus is considered vital to increasing available P for plant uptake. We measured both root and soil phosphatase throughout depth and alongside a variety of root and soil factors to better understand the potential of roots and soil biota to increase P availability and to constrain estimates of the biochemical mineralization within ecosystem models. We measured soil phosphatase down to 1 m, root phosphatase to 30 cm, and collected data on fine‐root mass density, specific root length, soil P, bulk density, and soil texture using soil cores in four tropical forests within the Luquillo Experimental Forest in Puerto Rico. We found that soil phosphatase decreased with soil depth, but not root phosphatase. Furthermore, when both soil and root phosphatase were expressed per soil volume, soil phosphatase was 100‐fold higher that root phosphatase. Both root and soil factors influenced soil and root phosphatase. Soil phosphatase increased with fine‐root mass density and organic P, which together explained over 50% of the variation in soil phosphatase. Over 80% of the variation in root phosphatase per unit root mass was attributed to specific root length (positive correlation) and available (resin) P (negative correlation). Synthesis: Fine‐root traits and soil P data are necessary to understand and represent soil and root phosphatase activity throughout the soil column and across sites with different soil conditions and tree species. These findings can be used to parameterize or benchmark estimates of biochemical mineralization in ecosystem models that contain fine‐root biomass and soil P distributions throughout depth.
Human polyomaviruses genomes in clinical specimens of colon cancer patients

Colon cancer is the third cause of cancer death in the developed countries. Some environmental factors are involved in its pathogenesis, including viral infections. The possible involvement of human polyomaviruses (HPyVs) in colon cancer pathogenesis has been previously reported, leading to inconsistent conclusions. Clinical specimens were collected from 125 colon cancer patients. Specifically, 110 tumor tissues, 55 negative surgical margins, and 39 peripheral blood samples were analyzed for the presence of six HPyVs: JC polyomavirus (JCPyV), BK polyomavirus (BKPyV), Merkel cell PyV (MCPyV), HPyV −6, −7, and −9 by means of DNA isolation and subsequent duplex Real Time quantitative polymerase chain reaction. HPyVs genome was detected in 33/204 samples (16.2%): the significant higher positivity was found in tumor tissues (26/110, 23.6%), followed by negative surgical margins (3/55, 5.5%, p < .05), and peripheral blood mononuclear cells (PBMCs) (4/39; 10.3%). HPyVs load was statistically higher only in the tumor tissues compared to negative surgical margins (p < .05). Specifically, MCPyV was detected in 19.1% (21/110) of tumor tissues, 3.6% (2/55) of negative surgical margins (p < .05), and 7.7% (3/39) of PBMCs; HPyV‐6 in 2.7% (3/110) of tumor tissues, and 1.8% (1/55) of negative surgical margins; one tumor tissue (1/110, 0.9%) and one PBMCs sample (1/39, 2.6%) were positive for BKPyV; JCPyV was present in 0.9% (1/110) of tumor tissues. HPyV‐7 and 9 were not detected in any sample. High prevalence and load of MCPyV genome in the tumor tissues might be indicative of a relevant rather than bystander role of the virus in the colon tumorigenesis.
Clubroot Disease Stimulates Early Steps of Phloem Differentiation and Recruits SWEET Sucrose Transporters within Developing Galls[CC-BY]

Plasmodiophora brassicae stimulates phloem differentiation and expression of phloem-specific SWEET transporters to hijack host metabolism. Successful biotrophic plant pathogens can divert host nutrition toward infection sites. Here we describe how the protist Plasmodiophora brassicae establishes a long-term feeding relationship with its host by stimulating phloem differentiation and phloem-specific expression of sugar transporters within developing galls. Development of galls in infected Arabidopsis (Arabidopsis thaliana) plants is accompanied by stimulation of host BREVIS RADIX, COTYLEDON VASCULAR PATTERN, and OCTOPUS gene expression leading to an increase in phloem complexity. We characterized how the arrest of this developmental reprogramming influences both the host and the invading pathogen. Furthermore, we found that infection leads to phloem-specific accumulation of SUGARS WILL EVENTUALLY BE EXPORTED TRANSPORTERS11 and 12 facilitating local distribution of sugars toward the pathogen. Utilizing Fourier-transform infrared microspectroscopy to monitor spatial distribution of carbohydrates, we found that infection leads to the formation of a strong physiological sink at the site of infection. High resolution metabolic and structural imaging of sucrose distributions revealed that sweet11 sweet12 double mutants are impaired in sugar transport toward the pathogen, delaying disease progression. This work highlights the importance of precise regulation of sugar partitioning for plant–pathogen interactions and the dependence of P. brassicae’s performance on its capacity to induce a phloem sink at the feeding site.
Ribonucleoprotein Capture by in Vivo Expression of a Designer Pentatricopeptide Repeat Protein in Arabidopsis[OPEN]

Artificial proteins built from consensus PPR motifs bind the intended RNA in vivo and can be used as RNA affinity tags to purify endogenous RNPs and identify the bound proteins. Pentatricopeptide repeat (PPR) proteins bind RNA via a mechanism that facilitates the customization of sequence specificity. However, natural PPR proteins have irregular features that limit the degree to which their specificity can be predicted and customized. We demonstrate here that artificial PPR proteins built from consensus PPR motifs selectively bind the intended RNA in vivo, and we use this property to develop a new tool for ribonucleoprotein characterization. We show by RNA coimmunoprecipitation sequencing (RIP-seq) that artificial PPR proteins designed to bind the Arabidopsis (Arabidopsis thaliana) chloroplast psbA mRNA bind with high specificity to psbA mRNA in vivo. Analysis of coimmunoprecipitating proteins by mass spectrometry showed the psbA translational activator HCF173 and two RNA binding proteins of unknown function (CP33C and SRRP1) to be highly enriched. RIP-seq revealed that these proteins are bound primarily to psbA RNA in vivo, and precise mapping of the HCF173 and CP33C binding sites placed them in different locations on psbA mRNA. These results demonstrate that artificial PPR proteins can be tailored to bind specific endogenous RNAs in vivo, add to the toolkit for characterizing native ribonucleoproteins, and open the door to other applications that rely on the ability to target a protein to a specified RNA sequence.
