Abstract
Background: The aim of this study was to establish a computer-aided automated method for cephalometric superimposition and to evaluate the accuracy of this method based on free-hand tracing.
Methods: Twenty-eight pairs of pre-treatment (T 1 ) and post-treatment (T 2 ) cephalograms were selected. Structural superimpositions of the cranial base, maxilla and mandible were independently completed by three operators performing traditional hand tracing methods and by computerized automation using the feature matching algorithm. To quantitatively evaluate the differences between the two methods, the hand superimposed patterns were digitized. After automated and hand superimposition of T 2 cephalograms to T 1 cephalometric templates, landmark distances between paired automated and hand T 2 cephalometric landmarks were measured. Differences in hand superimposition among the operators were also calculated.
Results: The T 2 landmark differences in hand tracing between the operators ranged from 0.61 mm to 1.65 mm for the three types of superimposition. There were no significant differences in accuracy between hand and automated superimposition (p > 0.05).
Conclusions: Computer-aided cephalometric superimposition provides comparably accurate results to those of traditional hand tracing and will provide a powerful tool for academic research.
Trial registration: The clinical trial was registered on April 1 st 2016. The registration number is ChiCTR1800017694, and URL is: http://www.chictr.org.cn/showproj.aspx?proj=29144

Abstract
Background: Unravelling the genetic architecture of agronomic traits in walnut such as budbreak date and bearing habit, is crucial for climate change adaptation and yield improvement. A Genome-Wide Association Study (GWAS) using multi-locus models was conducted in a panel of 170 walnut accessions genotyped using the Axiom™ J. regia 700K SNP array, with phenological data from 2018, 2019 and legacy data. These accessions come from the INRAE walnut germplasm collection which is the result of important prospecting work performed in many countries around the world. In parallel, an F 1 progeny of 78 individuals segregating for phenology-related traits, was genotyped with the same array and phenotyped for the same traits, to construct linkage maps and perform Quantitative Trait Loci (QTLs) detection. Results: Using GWAS, we found strong associations of SNPs located at the beginning of chromosome 1 with both budbreak and female flowering dates. These findings were supported by QTLs detected in the same genomic region. Highly significant associated SNPs were also detected using GWAS for heterodichogamy and lateral bearing habit, both on chromosome 11. We developed a Kompetitive Allele Specific PCR (KASP) marker for budbreak date in walnut, and validated it using plant material from the Walnut Improvement Program of the University of California, Davis, demonstrating its effectiveness for marker-assisted selection in Persian walnut. We found several candidate genes involved in flowering events in walnut, including a gene related to heterodichogamy encoding a sugar catabolism enzyme and a cell division related gene linked to female flowering date. Conclusions: This study enhances knowledge of the genetic architecture of important agronomic traits related to male and female flowering processes and lateral bearing in walnut. The new marker available for budbreak date, one of the most important traits for good fruiting, will facilitate the selection and development of new walnut cultivars suitable for specific climates.

Published: February 2020

Abstract
Background: Sports participants are faced with the decision to continue or cease play when injured. The implications of playing sport while injured on joint health and health-related quality of life (HRQoL) has not been investigated. The purpose of this study was to investigate the relationship between having played sport while injured and HRQoL, osteoarthritis, and persistent joint pain; and compare findings in elite and recreational cricketers.

Methods: The Cricket Health and Wellbeing Study cohort was used for this study. Inclusion criteria were: age ≥18 years, played ≥1 cricket season. Questionnaire data collected included a history of playing sport injured, SF-8 (physical (PCS) and mental (MCS) component scores), physician-diagnosed osteoarthritis, and persistent joint pain (most days of the last month). Multivariable linear regressions and logistic regressions were performed. Continuous covariates were handled using fractional polynomials. Models were adjusted for age, sex, cricket-seasons played, playing status, joint injury, and orthopaedic surgery. All participants (n=2,233) were included in HRQoL analyses, only participants aged ≥30 years (n=2,071) were included in osteoarthritis/pain analyses.

Results: Of the 2,233 current and former cricketers (mean age: 51.7 SD 14.7, played 30 IQR 24 cricket seasons, 60% were current cricketers, 62% played recreationally; median PCS: 51.4 IQR 9.0; MCS: 54.3 IQR 8.6) 1719 (77%) had played sport while injured. People who had played sport injured reported worse adjusted PCS (Effect(95% CI): -1.78(-2.62, -0.93) and MCS (-1.40(-2.25, -0.54), had greater odds of osteoarthritis (adjusted OR(95% CI): 1.86(1.39, 2.51) and persistent joint pain (2.34(1.85, 2.96)), compared to people who had not played sport injured. Similar relationships were observed regarding PCS, osteoarthritis and pain in elite and recreational subgroups. Playing injured was only related to worse MCS scores for elite cricketers (-2.07(-3.52, -0.63)); no relationship was observed in recreational cricketers (-0.70(-1.79, 0.39)).

Conclusion: Cricketers that had played sport injured had impaired HRQoL, increased odds of osteoarthritis and persistent joint pain, compared to those who had not played sport injured. Playing sport injured was only related to impaired mental-components of HRQoL in elite cricketers. The long-term impact of playing injured, should be considered when advising athletes on their ability to compete.

Abstract
Background A consensus has been reached that carbapenem-resistant Enterobacteriaceae (CRE) screening in immunosuppressed individuals can reduce the incidence of CRE bloodstream infection (BSI).
Methods We retrospectively studied the clinical data of 395 consecutive HSCT patients from September 2017 to April 2019. From September 2017 to June 2018 (period 1), 200 patients received single CRE screening before transplantation. From July 2018 to April 2019 (period 2), 195 patients received continuous weekly CRE screening after admission. For patients colonized with CRE, targeted managements were received: (1) contact precautions and (2) preemptive CRE-targeted treatment if necessary.
Results During period 1, 3 patients with CRE colonization were detected (1.5%). The CRE BSI rate was 2.0% (4 patients), and the related 30-day mortality was 50.0% (2 out of 4 patients). During period 2, 21 patients with CRE colonization were detected, and the detection rate was significantly higher than that in period 1 (P<0.001). Of the 21 colonized patients, 4 (19.0%) patients were identified as positive for CRE at the first screening, 5 (23.8%) were identified at the second screening, and the remaining 12 (57.1%) were identified at the third or later screening. The CRE BSI rate decreased to 0.5% (1/195), and there were no CRE-related death.
Fifteen colonized patients developed neutropenic fever. Thirteen colonizers were preemptively treated with tigecycline within 24 hours of fever onset, and they achieved rapid temperature control. One colonizer received tigecycline later than 48 hours after fever onset and ultimately survived due to the addition of polymyxin. The other received tigecycline later than 72 hours after fever onset and died of septic shock.
Conclusion The increase in screening frequency contributed to the detection of patients with CRE colonization. Targeted managements for these colonized patients may contribute to reducing the incidence and mortality of CRE BSI, therefore improving the prognosis of patients.

Abstract
Background: Detox diet are known as a popular dieting strategies that helps toxins elimination and weight manage but there is very little clinical evidence. Methods: To evaluate the effects of 4 week intake of the Wellnessup diet (WD) on toxic trace element detoxification, body fat reduction, and safety parameters. Forty-five women with body mass index (BMI) of 23.5-30 kg/m 2 were recruited. Thirty of them were assigned 1:1 to the test group (WD, 15 subjects) and control group 1 (calorie-restricted diet, CRD, 15 subjects) in a single blind and randomized, and the remaining 15 subjects were assigned to control group 2 (maintaining regular diet, MRD). The primary outcome were toxic trace element levels in hair (29 types of heavy metals), and the secondary outcomes were changes in anthropometric and urinary organic acids. Results: The levels of four toxic trace elements in hair decreased in the WD group after the diet compared to before the diet. Ni, Rh, Sn, and Ga were significantly lower in the WD group than in the CRD or MRD group (p<0.05). A significant weight loss in both groups (WRD:-1.88±0.95kg; p<0.013, CRD:-3.22±0.48kg; p<0.01). The BMI, fat free mass and hip circumference (HC) of the CRD group were not only significantly decreased compared to the WD group but also Weight, BMI. Body fat mass, fat free mass, waist circumference, and HC were significantly decreased (p<0.05) compared to the MRD group, and the weight loss was a greater decrease was observed in the CRD group. No significant changes in any safety parameter were observed. Conclusions: Use of WD might have several beneficial effects and safety such as body fat reduction and improving some the element detoxification through caloric restriction but did not reducing body fat mass more than calorie-restricted diet.

Abstract
Objectives Physical frailty is geriatric syndrome and can increase the risk of adverse outcome in the older population. Heart diseases are associated with physical frailty but a few studies in community-dwelling old population. Therefore the aim of this study was to examine the association between heart diseases, social factors, and physical frailty in community-dwelling older populations including the oldest old people. Methods The cross-sectional study included 1882 participants in community-dwelling older and oldest-old people in three age groups: 73 (±1), 83 (±1), and 93(±1) from both urban and rural areas of Japan. Questionnaires on medical history, psycho-social factors, blood samples, physical examinations, the hand grip strength test, and gait speed were measured at the venue. Physical frailty was defined based on a slow gait speed or weak grip strength. Heart diseases were assessed by self-reported questionnaires. Social interaction was based on the frequency of going outdoors and direct social contact. Analyses were conducted mainly using multiple logistic regression with adjustments for physical frailty risk factors. Results Heart disease subjects had a higher prevalence of physical frailty than those without heart disease (slow gait speed: 69.6 vs. 56.2%, p<.001; slow gait speed or weak grip strength: 80 vs. 69.6%, p=.002). After adjusting the covariate factors, heart diseases were associated with a slow gait speed (OR=1.5; 95%CI: 1.03-2.20, p=.035). Social interaction was associated with a slow gait speed (frequency of going outdoors: OR=0.87, 95%CI 0.79-0.9, p=.008; frequency of direct social contact: OR=0.88, 95%CI 0.82-0.95, p=.001), a weak grip strength (frequency of going outdoors: OR=0.86, 95%CI 0.77-0.96, p=.005), and with physical frailty (frequency of going outdoors: OR=0.84, 95%CI 0.75-0.94, p=.002; frequency of direct social contact: OR=0.89, 95%CI 0.82-0.97, p=.007). Living alone and frequency of direct social contact were associated with physical frailty among heart disease patients. Conclusions Our findings indicate that in community-dwelling older people, heart diseases and social interaction were associated with physical frailty. Older people with heart disease, those living alone and the frequency of direct social contact were associated with physical frailty. Future research must involve a longitudinal study to clarify the causal relationship.

Abstract
Objective High expression of VEGF in ovarian tissue, serum and follicular fluid of PCOS women is involved in the physiological and pathogenesis processes of PCOS. Our objective was to investigate the effect of sRAGE on VEGF expression and EGF-like growth factor in PCOS ovarian granulosa cells. Methods We collected ovarian granulosa cells of PCOS patients who underwent in vitro fertilization (IVF). Then treatment ovarian granulosa cells with different concentrations of sRAGE. Levels of VEGF, AREG, BTC and EREG mRNA were examined by quantitative RT-PCR. The protein levels of VEGF, AREG, BTC and EREG were measured by ELISA. Results Treatment with sRAGE decrease the production of VEGF, and the effects were dependent on the concentrations of sRAGE ( P <0.05). Simultaneously, the expression of the EGF-like growth factors AREG, BTC and EREG were decreased, and the expression were dependent on the concentrations of sRAGE ( P <0.05). Conclusions sRAGE may downregulate VEGF expression via EGF-like growth factor pathway in PCOS ovarian granulosa cells.

Published: February 2020

Abstract
Background Diabetes mellitus (DM) is an important risk factor in the long-term outcomes of surgical revascularization. However, few studies have focused on patients with left ventricular dysfunction (LVD) and DM, and the results are controversial. This study aimed to evaluate the effect of DM on the long-term outcomes of patients with ischemic heart disease (IHD) and LVD undergoing coronary artery bypass grafting(CABG). Methods In this propensity-matched study, patients with IHD and LVD who underwent CABG in our hospital from January 2007 to December 2017 were enrolled. The patients were divided into two groups according to whether they had DM. The primary endpoint was all-cause death, and the secondary endpoint was a composite of all-cause death, stroke, recurrent myocardial infarction, and re-revascularization. Results There was no significant difference in all-cause mortality between the two groups(5.78%vs.4.05%,P=0.216). The incidence of main adverse cardiovascular and cerebrovascular events(MACCE) in the secondary endpoint was significantly higher in the DM group than in the non-DM group (10.40% vs. 8.09%, P=0.023).Conclusions DM can negatively affect the long-term outcome of patients with IHD and LVD undergoing CABG by significantly increasing the overall incidence of MACCE, though the long-term survival doesn’t show significant difference between the DM and non-DM patients.
Prediction of mechanical properties and fatigue life of nano silver paste in chip interconnection
Authors: YANG Hui , Wu Jihui 
Published: February 2020

Abstract
The simulation of nano-silver solder joints in flip-chips is performed by the finite element software ANSYS, and the stress-strain distribution results of the solder joints are displayed. In this simulation, the solder joints use Anand viscoplastic constitutive model, which can reasonably simulate the stress and strain of solder joints under thermal cycling load. At the same time this model has been embedded in ANSYS software, so it is more convenient to use. The final simulation results show that the areas where the maximum stresses and strains occur at the solder joints are mostly distributed in the contact areas between the solder joints and the copper pillars and at the solder joints. During the entire thermal cycling load process, the area where the maximum change in stress and strain occurs is always at the solder joint, and when the temperature changes, the temperature at the solder joint changes significantly. Based on comprehensive analysis, the relevant empirical correction calculation equation is used to calculate and predict the thermal fatigue life of nano-silver solder joints. The analysis results provide a reference for the application of nano-silver solder in the electronic packaging industry.

Abstract
Background

Several studies have previously reported that propolis and its ingredients inhibit glioma cancer cell lines. The chemical composition and antiproliferative activity of propolis from Poland (PPE) and propolis from New Zealand (MPE) were compared in this study.

Methods

The chemical composition was investigated by gas chromatography-mass spectrometry. Antiproliferative activity of PPE and MPE was determined by a cytotoxicity test and DNA binding by [ 3 H]-thymidine incorporation on Human Diffuse Astrocytoma cell line (DASC) derived from a patient with a Grade II glioma and glioblastoma multiforme T98G and LN-18 cell lines from American Type Culture Collection.

Results

The chemical composition of both propolis was comparable, with marginal differences in the amount of some compounds. Flavonoids and chalcones, of which pinocembrin, pinobanksin, pinobanksin 3-acetate, chrysin and galangin showed the highest level, were the main components of both examined propolis (PPE–49.4% and MPE–52.1%). The performed cytotoxicity test showed powerful activity of PPE and MPE propolis on DASC, T98G and LN-18 cells. The degree of the antiproliferative activity was similar in the case of both propolis (viability after 72 h for 30 µg/mL ranged from 22.0% to 51.6% and proliferation inhibition after 72 h approximately was from 18.6% to 75.6%).

Conclusions

These results are the first to show that propolis from Poland and propolis from New Zealand have a strong cytotoxic and antiproliferative effect on DASC (Grade II glioma) derived from a patient and glioblastoma multiforme T98G and LN-18 cell lines. This activity may be associated with the high content of polyphenolic compounds in both propolis. These findings suggest that Polish and New Zealand propolis shows promising anticancer activity in the treatment of glioblastoma. However, further studies are required.

Abstract
Background: Nowadays, Ehrlichia canis receives more attention because of its great morbidity and mortality in animals. Dogs in the subclinical and chronic phases can be asymptomatic, and serologic tests show cross-reactivity and fail to differentiate between current and past infections. Moreover, there could be low parasitaemia, and E. canis might be found only in target organs, hence negative by PCR in blood. Methods: We evaluated by PCR the prevalence of E. canis in blood, liver, spleen, lymphatic nodules, and bone marrow in 59 recently euthanized dogs that had ticks but were clinically healthy. Results: In total, 52.55% of the blood PCRs for E. canis were negative, yet 61.30% yield positive results in tissue biopsies as follows: 63.15% from bone marrow, 52.63% from liver, 47.36% from spleen and 15.78% from lymphatic nodules. In addition, 33% had infection in three tissues (spleen, liver and bone marrow). Conclusions: Our results show prevalence of E. canis in tissue from dogs that were negative by PCR in blood. E. canis DNA in tissue was 30% lower in dogs that tested negative in blood samples by PCR, compared to those that were positive. However, it must be taken into account that some dogs with negative results were positive for E. canis in others tissues.
