Published: October 2020

Abstract
Background: Non-professional phagocytosis is usually triggered by stimuli such as necrotic cell death. In tumor therapy, the tumors often disappear slowly and only long time after the end of therapy. Here, tumor therapy inactivates the cells by inducing senescence. Therefore, study focused whether senescence is a stimulus for non-professional phagocytosis or whether senescent cells themselves phagocytize non-professionally.Results: Senescence was induced in cell lines by camptothecin and a phagocytosis assay was performed. In tissue of a cohort of 192 rectal cancer patients senescence and non-professional phagocytosis was studied by anti-histone H3K9me3 and anti-E-cadherin staining. Senescent fibroblasts and pancreas carcinoma cells phagocytize necrotic cells but are not phagocytized. In the tissue of rectal carcinoma, senescent cells can phagocytize and can be phagocytized. A high number of senescent cells and, at the same time, high numbers of non-professional phagocytizing cells in the rectal carcinoma tissue lead to an extremely unfavorable prognosis regarding overall survival.Conclusion: Senescent cells can be non-professionally phagocytized and at the same time they can non-professionally phagocytize in vivo. In vitro experiments indicate that it is unlikely that senescence is a strong trigger for non-professional phagocytosis. Combined high rates of non-professional phagocytosis and high rates of senescence are an extremely poor prognostic factor for overall survival.

Abstract
Background: Previous study has reported that circulating tumor cells (CTCs) could be served as a diagnostic biomarker in breast cancer (BC) screening. However, the differential efficacy of routine examination including ultrasound (US), mammogram (MG), magnetic resonance imaging (MR), and breast-specific gamma imaging (BSGI) and CTCs is unknown. This study aimed to compare CTCs with common used BC screening imaging modalities and to evaluate whether their combination would enhance the diagnostic potency in non-metastatic BC patients.Methods: 102 treatment-naive non-metastatic BC patients, 177 patients with breast benign diseases (BBD) and 64 healthy females, who had CTC detection and at least one of the following medical imaging examinations, US, MG or MR between December 2017 and November 2018, were enrolled in this study.Correlations of CTC enumeration with patients’ clinicopathological characteristics and medical imaging examinations were evaluated. Results: CTC detection rates (average CTC counts) in stage I-III BC patients were 92.9% (2.1), 87.2% (2.4) and 100% (4.2), respectively. CTCs counts were positively associated with cancer stage (p = 0.0084) and tumor size (p = 0.0301). CTC counts were more correlated with US than MR or MG. CTC counts were not associated with molecular subtypes of BC nor breast-specific gamma imaging (BSGI) results, indicating that CTC enumeration cannot be used to predict molecular signatures of BC. CTCs and medical imaging examinations would have the best diagnostic performance for BC when CTC cut-off was set to 2 and imaging Breast Imaging-Reporting and Data System (BI-RADS) was set to 4b. Combination of CTC with US, MG or MR increased the sensitivity for BC diagnosis, especially for MG. Sensitivity of MG increased from 0.694 to 0.917, even more than in conjugation with US (0.901). Conclusion: CTCs counts can be used as a diagnostic aid in BC screening and early diagnosis. CTCs counts were more relevant to US than MR or MG. Conjugation of CTCs counts would improve the diagnostic potency of medical imaging examinations for diagnosing BC, especially for MG in Chinese women.

Published: October 2020

Abstract
Background: Refaunation/rewilding by large ungulates represents a cost-efficient approach to managing natural biotopes and may be particularly useful for areas, whose biodiversity depends on disturbance dynamics and is imperilled by successional changes. To study impacts of refaunation on invertebrates, we focused on butterflies inhabiting the former military training range Milovice, Czech Republic, refaunated since 2015 by a combination of Exmoor pony (“wild” horse), Tauros cattle (“aurochs”) and European wisent.Methods: We compared butterfly presence-absence patterns immediately after the military use termination (early 1990s), prior to the refaunation (2009) and after it (2016–19); and quantitative data gained by monitoring butterflies at refaunated and neglected plots. We used the correspondence analysis for the presence-absence comparison and the canonical correspondence analysis for the quantitative data, and related results of both ordination methods to the life history, climatic and conservation-related traits of recorded butterflies. Results: Following the termination of military use, several poorly mobile species inclining towards oceanic climates were lost. Newly gained species are more mobile and prefer warmer continental conditions. The numbers of butterfly species did not differ between refaunated and neglected plots, but the former hosted higher abundances. Butterflies developing on coarse grasses and shrubs inclined towards neglected plots, whereas refaunated plots supported species developing on small forbs. Conclusion: The changes in species composition following the cessation of military use were attributable to successional change, coupled with climate-driven changes in species pool. By blocking succession, large ungulates support butterflies depending on competitively poor plants. Restoring large ungulates populations represents a great hope for conserving specialised insects, provided that settings of the projects, and locally adapted ungulate densities, do not deplete resources for species with often contrasting requirements.

Abstract
Background: Reproduction is a basic prerequisite to efficient livestock production. Reproductive performance depends upon the normal structure and function of genital organs. Methods: A cross-sectional study was conducted from November 2016 to May 2017 to identify and compare the frequency of pathological lesions in the reproductive tract and to isolate bacteria associated to uterine lesions in female dromedary camels and cows slaughtered at Akaki camel slaughter house and Addis Ababa and Adama municipal abattoirs. Abattoirs were visited once per week for 28 weeks during which three to seven animals on average were slaughtered per day. A purposive sampling technique was employed to examine reproductive tracts of all slaughtered animals (280; 140 cows and 140 camels). Following gross inspection at abattoirs, tissue samples with lesion were collected for histopathological and bacteriological investigation. Result: Various pathological lesions with different degrees of severity were observed in 48 (34.2%) and 51 (36.4%) of dromedary camels and cows, respectively. Uterine lesions were the most prevalent 21.4% lesions observed in dromedary camels followed by ovarian lesions 7.14%; while in cows, ovarian lesions were the major prevalent 16.4% lesions followed by uterine lesion 14.2%. The result showed that there were 56 bacteria isolated from cows uterine lesion with Staphylococcus species 28.5%, Streptococci species 19.6%, Coynebacterium species 8.9%, Escherichia coli 26.78%, Salmonella species 10.7% and Klebsiella species 5.35% being the prominent isolates; while in camels, there were 45 bacteria isolated with Escherichia coli 35.5%, Staphylococcus species 26.6%, Streptococcus species 13.3%, Pseudomonas species 6.6 %, Proteus species 4.4%, Salmonella species 8.8% and Klebsiella species 4.4% being the most frequently isolated. The result showed that the major isolates were similar with slightly higher in cows. Histopathologically, endometrial glands degeneration, sloughing of epithelium, peri-glandular cuffing and infiltrations of inflammatory cell were some of characteristic changes observed in uterus. Conclusions: Pathological lesions in reproductive organs in female dromedary camels and cows showed great prevalence, with similarity in bacterial isolates between the two species. The role of each reproductive lesions and bacterial isolates incriminated as causes of reproductive failures in this livestock species needs further investigation.

Published: October 2020

Abstract
Background: Legumes comprise important crops that offer major agronomic benefits, including the capacity of establishing symbiosis with rhizobia, fixing atmospheric N2. It has been proven that legumes are particularly susceptible to boron (B) stress, which leads to important yield penalties. Boron (B) deficiency or toxicity in plants causes the inhibition of growth and an altered development. Under such conditions, the participation of two distinct protein families (the major intrinsic protein family MIP and the Boron transporter family BOR) is required to minimize detrimental effects caused by B stress. However, in legumes, little is known about the transport mechanisms responsible for B uptake and distribution, especially under deficiency. Results: A Medicago truncatula protein, MtNIP5;1 (Medtr1g097840) (homologous to the Arabidopsis thaliana AtNIP5;1) was identified as a novel legume B transporter involved in B uptake under deficiency. Further analyses revealed that this M. truncatula aquaporin expression was boron-regulated in roots, being induced under deficiency and repressed under toxicity. It localizes at the plasma membrane of root epidermal cells and in nodules, where B plays pivotal roles in symbiosis. Furthermore, the partial complementation of the nip5;1-1 A. thaliana mutant phenotype under B deficiency supports a functional role of MtNIP5;1 as a B transporter in this legume model plant. Conclusions: The results here presented support a functional role of MtNIP5;1 in B uptake under deficiency and provides new insights into B transport mechanisms in legume species.

Abstract
The restoration of incomplete artifacts is important for presenting the value of artifacts. Even though the existing methods provide rich solutions for the restoration of artifacts, they may not be the ultimate and perfect methods. The innovation of restoration methods may provide better restoration effects in some aspects or bring people a different visiting experience, which motivates people to explore new restoration methods. In this paper, based on virtual imaging technology, a virtual imaging restoration method for incomplete artifacts were proposed. In order to examine the effects and potential of the virtual imaging restoration, a bronze mirror and a mural were restored through our newly invented virtual imaging restoration device. The effects of the restorations were evaluated through the illumination test and the questionnaire surveys. The results proved that the virtual imaging restoration can visually achieve in-situ restoration, and it is completely reversible. Virtual imaging restoration also performed well in terms of visiting experience, authenticity, discernibility, and economy. Limitations of this restoration method are related to the scope of application, the viewing angle, and the imaging effects. Overall, virtual imaging restoration is worth recommending and the potential of this method and its encouraging results may provide a choice or pretest tool for the restoration of some incomplete artifacts in the near future.

Abstract
Background: Neonatal jaundice is one of the most common problems in newborns. Effective treatment of jaundice requires therapeutic intervention with phototherapy. Over recent years, several studies reported fiberoptic phototherapy to be less effective than conventional phototherapy in term neonates. Our study aimed to compare the effectiveness of fiberoptic phototherapy with a larger illuminated area and higher irradiance to conventional phototherapy methods.
Methods: This was a randomized controlled trial conducted at Kilimanjaro Christian Medical Centre (KCMC). A total of 41 term neonates, less than 7 days of age with unconjugated hyperbilirubinemia were randomized. Thirteen (13) newborns were allocated to receive fiberoptic phototherapy, 13 to blue light conventional phototherapy and 15 to white light conventional phototherapy. Effectiveness was assessed by comparing the duration of phototherapy, bilirubin reduction rate and side effects of treatment. The data was analyzed with the independent t-test.
Results: The mean overall bilirubin reduction rate was comparable in the fiberoptic phototherapy group (0.74%/h) and the blue light conventional phototherapy group (0.84%/h), with no statistically significant difference ( p -value 0.124). However, white light conventional phototherapy had a significantly lower mean overall bilirubin reduction rate (0.29%/h) as compared to fiberoptic phototherapy ( p -value <0.001). The mean treatment duration of phototherapy was 69 h, 68 h and 90 h in the fiberoptic, blue light conventional and white light conventional phototherapy groups respectively. Side effects such as loose stool and skin rash were noted in some participants who received conventional phototherapy. No side effects of treatment were noted in the fiberoptic phototherapy group.
Conclusion: The effectiveness of fiberoptic PT and blue light conventional PT were comparable in terms of bilirubin reduction rate and treatment duration, whereas fiberoptic phototherapy was more effective than white light conventional PT, with a significantly lower bilirubin reduction rate and treatment duration. Fiberoptic phototherapy may mitigate side effects caused by conventional phototherapy.

Abstract
Malaria is a disease affecting hundreds of millions of people across the world, mainly in developing countries and especially in Sub-Saharan Africa. It is the cause of hundreds of thousands of deaths each year and there is an ever-present need to identify and develop effective new therapies to tackle the disease and overcome increasing drug resistance. Here, we extend a previous study in which a number of partners collaborated to develop a consensus in silico model that can be used to identify novel molecules that may have antimalarial properties. The performance of machine learning methods generally improves with the number of data points available for training. One practical challenge in building large training sets is that the data are often proprietary and cannot be straightforwardly integrated. Here, this was addressed by sharing QSAR models, each built on a private data set. We describe the development of an open-source software platform for creating such models, a comprehensive evaluation of methods to create a single consensus model and a web platform called MAIP available at https://www.ebi.ac.uk/chembl/maip/. MAIP is freely available for the wider community to make large-scale predictions of potential malaria inhibiting compounds. This project also highlights some of the practical challenges in reproducing published computational methods and the opportunities that open-source software can offer to the community.

Published: October 2020

Abstract
Background: Breast cancer may impair health-related quality of life (HRQoL). We examined the mediating roles of perceived social support (PSS) and coping style (CS) in the relationship between resilience and HRQoL in newly diagnosed breast cancer patients.

Methods: Four-hundred thirty-one patients completed a survey at two hospitals in Shaanxi Province, China, using self-report measures assessing HRQoL, resilience, PSS, and CS. A one-sample t-test analyzed differences between resilience, PSS, and CS in breast cancer patients and the corresponding norm. Multivariate linear regression analyzed the independent predictors of HRQoL. The mediating roles of PSS and CS between resilience and HRQoL were investigated using structural equation modeling (SEM).

Results: Participants had significantly lower scores for resilience and PSS and higher scores for the avoidance and resignation CSs than their corresponding norm. SEM analysis showed resilience had significant direct effects on PSS (B = 0.59, 95% CI [0.49, 0.68], P = 0.003), CS (confrontation: B = 0.53, 95% CI [0.44, 0.62], P = 0.001; resignation: B = -0.66, 95% CI [-0.74, -0.57], P = 0.002), and HRQoL (B range from 0.54–0.58). Resilience had significant indirect effects (B range from 0.09–0.27), and PSS and CS had significant direct effects on HRQoL (P < 0.05).

Conclusions: Newly diagnosed breast cancer patients had lower resilience and PSS and higher negative CSs. PSS and CS appeared to mediate the influence of resilience on HRQoL. Multimodal intervention programs focusing on PSS and CS might increase the influence of resilience on HRQoL in breast cancer patients.

Abstract
Background: The northeastern part of the Qinghai-Tibet Plateau (QTP) presents a high number of plateau loach species. As one of the three major groups of fishes distributed on the QTP, plateau loach has high ecological value. However, the taxonomy and systematics of these fish are still controversial, and a large number of new species have been reported. The reason for this phenomenon is that the degree of morphological variation is low, the phylogenetic information provided by morphological and anatomical features used for species identification is relatively poor, and many cryptic species are observed. Based on the high-density sampling points from the biodiversity hotspots surveyed, this study aims to evaluate the biodiversity of plateau loach in the northeastern part of the QTP and reveal the hidden diversity by comparing morphological species with molecular operational taxonomic units (MOTUs).Results: After careful identification and comparison of the morphology and DNA barcoding of 1,630 specimens, 22 species were identified, with 20 considered valid local species and two identified as new species that had not been previously described. Based on the combination of morphological and molecular methods, a total of 24 native species were found, two of which were cryptic species: Triplophysa robusta sp1 and Triplophysa minxianensis sp1. Fourteen of the 24 species form clusters of barcodes that allow them to be reliably identified. The remaining cases involved 10 closely related species, including rapidly differentiated species and species that seemed to have experienced incomplete lineage sorting or showed introgressions.Conclusions: The results highlight the need to combine traditional taxonomies with molecular methods to correctly identify species, especially closely related species, such as the plateau loach. This study provides a basis for protecting the biodiversity of plateau loach.
Protein over-expression in Escherichia coli triggers adaptation analogous to antimicrobial resistance

Published: October 2020

Abstract
Background: The E. coli pET system is the most widely used protein over-expression system worldwide. It relies on the assumption that all cells produce target protein and it is generally believed that integral membrane protein (IMP) over-expression is more toxic than their soluble counterparts. Results: Using GFP-tagged proteins, high level over-expression of either soluble or IMP targets results in > 99.9 % cell loss with survival rate of only < 0.03 %. Selective pressure generates three phenotypes: large green, large white and small colony variants. As a result, in overnight cultures, ~50 % of the overall cell mass produces no protein. Genome sequencing of the phenotypes revealed genomic mutations that causes either the loss of T7 RNAP activity or its transcriptional downregulation. The over-expression process is bactericidal and is observed for both soluble and membrane proteins.Conclusions: We demonstrate that it is the act of high-level over-expression of exogenous proteins in E. coli that sets in motion a chain of events leading to > 99.9 % cell death. These results redefine our understanding of protein over-production and link it to the adaptive survival response seen in the development of antimicrobial resistance.
