Abstract
OBJECTIVE To sum up experience in unibody bifurcation stent graft in the treatment of abdominal aortic aneurysm with aortic bifurcation stenosis. METHODS Clinical data of 19 cases of abdominal aortic aneurysm and aortic bifurcation stenosis received endovascular treatment using unibody bifurcation stent graft in Zhejiang Provincial People's Hospital during March 2009 and March 2018 were collected. The clinical characteristics, surgery procedure and follow-up results were reviewed. RESULTS Stent graft was successful in all patients, and the average operation time was (70.0±2.3) min. Leakage was found in 3 patients, in which 2 patients with type Ⅰ leakage and 1 patient with type Ⅱ leakage. All leakage disappeared 15 days after surgery. The 19 cases were followed-up for 9-48 months with the median follow-up time of 27 months, and no displacement, leakage and lower limb ischemia was observed. CONCLUSIONS Unibody bifurcation stent graft is of satisfactory long-term effect for patients with abdominal aortic aneurysm and aortic bifurcation stenosis, and can avoid displacement of stent graft after operation.

Abstract
Alloy design based on single–principal-element systems has approached its limit for performance enhancements. A substantial increase in strength up to gigapascal levels typically causes the premature failure of materials with reduced ductility. Here, we report a strategy to break this trade-off by controllably introducing high-density ductile multicomponent intermetallic nanoparticles (MCINPs) in complex alloy systems. Distinct from the intermetallic-induced embrittlement under conventional wisdom, such MCINP-strengthened alloys exhibit superior strengths of 1.5 gigapascals and ductility as high as 50% in tension at ambient temperature. The plastic instability, a major concern for high-strength materials, can be completely eliminated by generating a distinctive multistage work-hardening behavior, resulting from pronounced dislocation activities and deformation-induced microbands. This MCINP strategy offers a paradigm to develop next-generation materials for structural applications.

Abstract
OBJECTIVE The role of routine central lymph node dissection (CLND) for clinically central lymph node negative (CN0) papillary thyroid microcarcinoma (PTMC) remains uncertain. We aim to determine the predictive factors for central lymph node metastasis (CLNM) in papillary thyroid microcarcinoma. PATIENTS AND METHODS A total of 273 patients diagnosed with clinically central lymph node negative PTMC from 2014 to 2016 were included. The predictive risk factors for CLNM were analyzed with respect to age, sex, tumor size, tumor multifocal, lymphadenectasis of lateral neck, capsular invasion, extra capsular spread (ECS), coexistence of chronic lymphocytic thyroiditis (Hashimoto thyroiditis, HT) and nodular goiter (NG), BRAFV600E mutation and subtype of papillary thyroid carcinoma (PTC). Univariate and multivariate analyses were performed to identify the risk factors for CLNM. RESULTS Among the 273 patients, the CLNM occurred in 80 patients (29.3%). By univariate and multivariate analyses, tumor size (OR 2.07; p<0.001), multifocal (OR 2.67; p<0.004), lymphadenectasis of lateral neck (OR 9.28; p<0.001), tumor extent (OR 42.01; p<0.001) were independently correlated with CLNM. In further study, dorsal part of solitary lesion (OR: 16.312, 95%CI: 3.349-79.455, p=0.001), capsular invasion (OR: 42.012, 95% CI: 5.209-338.861, p<0.001), 6<D≤9 (OR: 8.400, 95% CI: 1.866-37.807, p=0.006) and D=1 (OR: 11.455, 95% CI: 2.500-52.480, p=0.002) were more tended to have CLNM. CONCLUSIONS A prophylactic central lymph node dissection should be considered particularly to PTMC patients with each of tumor size > 6 mm, dorsal part of solitary lesion, multifocal, lymphadenectasis of lateral neck and capsular invasion.

Abstract
Until now, there are no completely effective parasite-specific pharmaceuticals or immunotherapies for treatment against the zoonotic cryptosporidiosis. Sushi domain (CpSushi) is an important functional domain in Cryptosporidium parvum putative rhoptry protein-1 (CpPRP1), which is the only reported C. parvum rhoptry protein and may play key role in the course of invasion. Here, a 708-bp fragment encoding the CpSushi domain was amplified and expressed in E. coli. Immunofluorescence detection showed that CpSushi was located on the surface of C. parvum oocysts and the apical pole to the sporozoites that belonged to the position of rhoptry. Three-week-old female ICR mice were used for detecting the immunoreactions and immunoprotection of recombinant CpSushi (rCpSushi) to artificial C. tyzzeri infection. The results indicated that a significant increase of anti-CpSushi antibody response was induced by the recombinant protein. Compared to blank, Tris-EDTA (TE) buffer and adjuvant controls mice, rCpSushi-immunized mice produced specific spleen cell proliferation as well as enhanced IL4, IL5, IL12p70 and TNF-α production in vitro. The reduction rate of parasites shedding in stool in mice immunized with rCpSushi was 68.91% after challenging with C. tyzzeri. These results suggest that CpSushi could be a new promising cryptosporidiosis vaccine candidate antigen composition.

Abstract
Abstract
The standard paradigm for cancer susceptibility genetic testing has been for patients to 1) be identified by their provider as being at high risk due to extensive family history or another diagnosis (e.g., breast cancer for ovarian risk testing), and 2) attend in–person pre and post– genetic test sessions with a genetic counselor to prepare for testing and learn about the results. This arrangement places boundaries around the types of women willing to spend this time and effort receiving testing, as providers are required to act as gatekeepers to the testing process. More open methods of accessing genetic testing and providing support need to be evaluated.
We propose to deliver personal, risk–based genetic testing and results to women from the general public using the Internet. Internet–based services offer several advantages over either in–person or telephone interventions. First, information can be accessed by participants and providers on their own schedules, at any location with internet access, and can be consumed at the pace and style that is best for individual tastes and styles. If necessary, information and support can be re–reviewed if the patient does not remember the initial counseling session. Second, delivery of information through the internet can be performed in a more efficient and cost–effective manner, reserving the limited in–person genetic counseling for individuals who need it the most, while providing support to the general public about basic medical and risk–based information. Recruitment via social media outlets can directly link potential participants to the Internet systems that screen for eligibility and provide testing support. Finally, Internet delivery can bring genetic testing to the patient in their home, eliminating a major barrier to testing (multiple visits to the provider)
The main objective of MAGENTA is to test the effects of on–line genetic education versus telephone genetic counseling on cancer distress and other psychological outcomes. We will recruit women using social media and other eHealth methods to participate in a randomized trial of ovarian cancer counseling and testing that is conducted online and using the telephone. We will conduct a (2x2 factorial design) randomized trial to test online versus telephone pre– and post–test genetic counseling for ovarian cancer risk among women at higher than average risk for ovarian cancer. We expect to enroll 3000 women through our media contacts to participate in MAGENTA. For genetic risk assessment, we will evaluate and provide feedback on 19 breast and ovarian cancer (OC) genes that have a clear relationship to cancer risk in collaboration with Color Genomics. Variants include ATM, BARD1, BRCA1, BRCA2, BRIP1, CDH1, CHEK2, EPCAM, MSH2, MSH6, MLH1, NBN, PALB2, PMS2, PTEN, RAD51C, RAD51D, TP53, and STK1. We will follow women for main psychological outcomes at 3 months post testing and longer for other outcomes.

Abstract
Essentials Ovarian vein thrombosis (OVT) is a rare but potentially serious condition. OVT is associated with postpartum, pelvic disease, surgeries, and other thrombophilic states. We report a case of idiopathic OVT in a healthy, premenopausal woman. OVT should be considered for abdominal pain in women even outside the postpartum range. SUMMARY Ovarian vein thrombosis (OVT) is a rare condition most often seen in the immediate postpartum period. We report a 40-year-old woman with no significant past medical or surgical history who presented to the emergency room for acute right lower quadrant pain of 1 day duration. A computed tomography (CT) scan showed a normal appendix but a new finding of right ovarian venous thrombosis. To date, only nine cases of idiopathic OVT have been reported. In this case report, we present a summary of these cases and review of literature regarding management of OVT.

Abstract
The coefficient of friction (COF) of metals is usually high, primarily because frictional contacts induce plastic deformation underneath the wear surface, resulting in surface roughening and formation of delaminating tribolayers. Lowering the COF of metals is crucial for improving the reliability and efficiency of metal contacts in engineering applications but is technically challenging. Refining the metals' grains to nanoscale cannot reduce dry-sliding COFs, although their hardness may be elevated many times. We report that a submillimeter-thick stable gradient nanograined surface layer enables a significant reduction in the COF of a Cu alloy under high-load dry sliding, from 0.64 (coarse-grained samples) to 0.29, which is smaller than the COFs of many ceramics. The unprecedented stable low COF stems from effective suppression of sliding-induced surface roughening and formation of delaminating tribolayer, owing to the stable gradient nanostructures that can accommodate large plastic strains under repeated sliding for more than 30,000 cycles.

Abstract
BACKGROUND Next-generation sequencing in cancer research may reveal germline variants of clinical significance. We report patient preferences for return of results and the prevalence of incidental pathogenic germline variants (PGVs). PATIENTS AND METHODS Targeted exome sequencing of 202 genes was carried out in 1000 advanced cancers using tumor and normal DNA in a research laboratory. Pathogenic variants in 18 genes, recommended for return by The American College of Medical Genetics and Genomics, as well as PALB2, were considered actionable. Patient preferences of return of incidental germline results were collected. Return of results was initiated with genetic counseling and repeat CLIA testing. RESULTS Of the 1000 patients who underwent sequencing, 43 had likely PGVs: APC (1), BRCA1 (11), BRCA2 (10), TP53 (10), MSH2 (1), MSH6 (4), PALB2 (2), PTEN (2), TSC2 (1), and RB1 (1). Twenty (47%) of 43 variants were previously known based on clinical genetic testing. Of the 1167 patients who consented for a germline testing protocol, 1157 (99%) desired to be informed of incidental results. Twenty-three previously unrecognized mutations identified in the research environment were confirmed with an orthogonal CLIA platform. All patients approached decided to proceed with formal genetic counseling; in all cases where formal genetic testing was carried out, the germline variant of concern validated with clinical genetic testing. CONCLUSIONS In this series, 2.3% patients had previously unrecognized pathogenic germline mutations in 19 cancer-related genes. Thus, genomic sequencing must be accompanied by a plan for return of germline results, in partnership with genetic counseling.
