Abstract
This article provides comprehensive experimental data of two water-swelling materials, water swelling rubber (WSR) and water-swelling polyurethane (WSP). Swelling tests, Dynamic Mechanical Analyzer (DMA) and Scanning Electron Microscope (SEM) were performed. Sealing properties of WSR and WSP were characterized by the data of swelling ratios (Sw and Sa), storage moduli (E') and images of micro-damage morphologies. These data can be useful for the prediction of the long-term waterproof performance of water-swelling materials and provide reference for material selection. The data presented herein was used for the article, titled "Laboratory evaluation of long-term sealing behaviors of two water-swelling materials for shield tunnel gasket" [1].

Abstract
While knowledge of early embryo development and viability has continually increased, there is still a need for noninvasive methods to identify embryos with the highest chances of development to term when transferred. The most widely used technique, morphological assessment, is highly subjective and limited by personnel experience. Spent media from invitro culture could be used as a valuable noninvasive marker for embryo quality assessment. Raman spectroscopy has proven to be a powerful tool for identifying the molecular characteristics of spent culture media by measuring vibration of chemical bonds, allowing for metabolomic profiling of varying stages and quality of embryos. It is well documented that embryos produced through somatic cell nuclear transfer (SCNT) result in lower pregnancy rates and higher incidences of pregnancy loss when compared with embryos produced through IVF (Heyman et al. 2002 Biol. Reprod. 66, 1-13). This study was designed to examine differences in spent media between bovine embryos produced by IVF and SCNT. The SCNT embryos with a metabolomic profile more similar to IVF embryos may have a higher developmental competence. Bovine cumulus-oocyte complexes (COCs) were retrieved from abattoir-derived ovaries and matured for 21h in maturation medium. After IVM, COCs were either used for IVF or SCNT and cultured in 50μL droplets of synthetic oviductal fluid medium + fetal bovine serum in groups of 45 from Day 0-5. On Day 5, embryos that had reached morula stage were placed in individual droplets of 13μL of synthetic oviductal fluid + bovine serum albumin until Day 7. All embryos were cultured at 38.5°C and 5% CO2. On Day 7 embryos were assessed for developmental stage and quality and 10μL of medium from individual culture drops was collected for Raman spectroscopy. Samples were loaded on an MgF2 optical window, dried, and analysed using a 785nm near-infrared laser in the spectral range of 600 to 1800cm−1. Raw Raman data were first pre-processed by baseline correction (asymmetric least-squares smoothing) and normalization. Principal component analysis and partial least squares were then applied to reduce data dimensions. The score of the most significant principal components from principal component analysis and the optimum number of scores from partial least squares were used for linear discriminant analysis. Spent media samples from 4 SCNT embryos, 3 IVF embryos, and 3 empty media samples were analysed, with 50 spectra obtained from each sample. Preliminary data showed grouping of medium containing embryos developed to blastocyst from medium containing embryos arrested at morula or empty medium. We also saw grouping of medium containing SCNT embryos from medium containing IVF embryos within both the morula and blastocyst stage from empty medium. This shows evidence of metabolomic differences between embryos of different developmental potential and embryos produced by IVF and SCNT. Further investigation of the Raman profile of these groups can display specific differences in chemical components and help to identify candidate genes causing differing metabolism of these groups.

Abstract
UNLABELLED We conducted a phenome-wide Mendelian randomization analysis (MR-PheWAS) to survey health effects associated with high normal serum calcium. We found causal evidence for conditions related to renal function, bone and joint health, and cardiovascular risk. These conditions collectively suggest that tissue calcification may be a key mechanism through which serum calcium influences health. INTRODUCTION Calcium is essential for the normal functioning of the cardiovascular system, muscles, and nerves. In this MR-PheWAS study, we sought to capture the totality of health effects associated with high normal serum calcium. METHODS We used data from up to 337,535 UK Biobank participants, and tested for associations between calcium genetic score (calcium-GS) and 925 disease outcomes, with follow-up analyses using complementary MR methods. RESULTS Calcium-GS was robustly associated with serum calcium concentration (F statistics = 349). After multiple testing correction (P < 1.62E-4), we saw genetic evidence for an association between high serum calcium and urinary calculus (OR per 1 mg/dl 3.5, 95%CI 1.3-9.2), renal colic (9.1, 95%CI 2.5-33.5), and allergy/adverse effect of penicillin (2.2, 95%CI 1.5-3.3). Secondary analyses with independent replication from consortia meta-analyses suggested further effects on myocardial infarction and osteoarthrosis. CONCLUSION We found causal evidence for effects of high normal serum calcium with conditions related to renal function, bone and joint health, and cardiovascular risk, which may collectively reflect influences on tissue calcification and immune function.

Abstract
Abstract
Tumors that overexpress the MYC oncogene, including most receptor triple-negative breast cancers, frequently demonstrate aneuploidy, numerical chromosome alterations associated with highly aggressive cancers. Aneuploidy is also associated with rapid tumor evolution and poor patient outcome. We identify that MYC overexpression induces reversible defects in microtubule nucleation and mitotic spindle assembly, in TNBCs and other epithelial cells, promoting chromosome segregation defects, micronuclei and chromosomal instability (CIN). High TPX2 expression is permissive for mitotic spindle assembly and chromosome segregation in cells with MYC overexpression; whereas TPX2 depletion blocks mitotic progression, induces cell death and prevents tumor growth. Attenuating MYC expression reverses mitotic defects, even in established breast tumor cell lines, implicating an ongoing role for high MYC in the persistence of CIN in cancers. Our studies implicate the MYC oncogene as a regulator of spindle assembly and identify a new MYC-TPX2 synthetic-lethal interaction in TNBC that could represent a future therapeutic strategy in MYC-overexpressing cancers. Moreover, our studies suggest that blocking MYC activity can attenuate the emergence of CIN and tumor evolution.

Abstract
A single-multi-single mode (SMS) fiber structure with spiral microgroove, fabricated by femtosecond laser inscription has been proposed and successfully employed for refractive index (RI) sensing. The multimode interference in the SMS structure is effectively affected by the external perturbation due to the microgroove, which goes deep into the core of the multimode fiber (MMF). Experimental results show that this femtosecond-induced spiral micro-structured SMS (FISM-SMS) fiber structure exhibits a linear response to eternal liquid refractive index in a large RI range of 1.3373-1.4345. The maximum sensitivity of the structure can reach to 2144 nm/RIU and can be further improved by increasing the depth of the spiral micro-grooves.

Abstract
Background & aims Prophylactic injections of factor VIII reduce the incidence of bleeds and slow the development of joint damage in people with hemophilia. The aim of this study was to identify optimal person-specific prophylaxis regimens for children with hemophilia A. Methods Analytic and numerical methods were used to identify prophylaxis regimens which maximize the time for which plasma factor VIII concentrations exceed a threshold, maximize the lowest plasma factor VIII concentrations, and minimize risk of bleeds. Results It was demonstrated analytically that, for any injection schedule, the regimen that maximizes the lowest factor VIII concentration involves sharing doses between injections so that all of the trough concentrations in a prophylaxis cycle are equal. Numerical methods were used to identify optimal prophylaxis schedules and explore the trade-offs between efficacy and acceptability of different prophylaxis regimens. The prophylaxis regimen which minimizes risk of bleeds depends on the person’s pattern of physical activity and may differ greatly from prophylaxis regimens that optimize pharmacokinetic parameters. Prophylaxis regimens which minimize risk of bleeds also differ from prophylaxis regimens that are typically prescribed. Predictions about which regimen is optimal are sensitive to estimates of the effects on risk of bleeds of factor VIII concentration and physical activity. Conclusion The methods described here can be used to identify optimal, person-specific prophylaxis regimens for children with hemophilia A.

Abstract
OBJECTIVE To evaluate the clinical validity of a new ultrahigh-throughput non-invasive prenatal test (NIPT) based on combinatorial probe-anchor ligation (cPAL) sequencing of cell-free fetal DNA (cffDNA) using centralized testing. METHODS Maternal plasma samples were obtained from 10 594 singleton pregnancies in high-risk populations at 20 centers in China, including 8155 that were collected retrospectively and 2439 prospectively. Fetal outcome data and karyotyping results were documented as gold standard and were double blinded during NIPT. The clinical performance of the ultrahigh-throughput sequencing method, cPAL, for NIPT was validated by evaluating its sensitivity, specificity and positive predictive value (PPV) in detecting trisomies 21, 18 and 13 as the centralized testing mode in the reference laboratory. To ensure stable and reproducible performance of centralized cPAL-based NIPT in detecting trisomies, a series of quality-control systems, including sequencing of two sets of artificial samples, were employed and evaluated. RESULTS Ten prospective cases were excluded from the study because of incomplete clinical data. Four prospective samples failed to generate a NIPT result due to assay failure, presenting a failure rate of 0.16% (4/2429). A total of 168 retrospective cases and 47 prospective cases had a positive NIPT result for trisomy, giving respective positive rates of 2.06% and 1.94%. Four false-positive and no false-positive cases were observed in the retrospective and prospective groups, respectively, resulting in PPV of 97.62% (95% CI, 94.02-99.35%) and 100% (95% CI, 92.45-100%), respectively. In the retrospective group, sensitivity and specificity were, respectively, 100% (95% CI, 97.07-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 21, 100% (95% CI, 97.75-100%) and 99.98% (95% CI, 99.94-100%) for trisomy 18, and 100% (95% CI, 15.81-100%) and 100% (95% CI, 99.95-100%) for trisomy 13. In the prospective group, sensitivity and specificity were, respectively, 100% (95% CI, 90.75-100%) and 100% (95% CI, 99.85-100%) for trisomy 21, 100% (95% CI, 63.06-100%) and 100% (95% CI, 99.85-100%) for trisomy 18, and 100% (95% CI, 2.50-100%) and 100% (95% CI, 99.85-100%) for trisomy 13. CONCLUSION In this multicenter study with a full quality-control system, NIPT by centralized cPAL-based testing showed high stability and performance comparable to those of previous validation studies in high-risk populations.

Abstract
This study aimed to determine whether psychological factors affect health-related
quality of life (HRQL) and recovery of knee function in total knee replacement (TKR)
patients. A total of 119 TKR patients (male: 38; female: 81) completed the Beck
Anxiety Inventory (BAI), Beck Depression Inventory (BDI), State Trait Anxiety
Inventory (STAI), Eysenck Personality Questionnaire-revised (EPQR-S), Knee Society
Score (KSS), and HRQL (SF-36). At 1 and 6 months after surgery, anxiety, depression,
and KSS scores in TKR patients were significantly better compared with those
preoperatively (P<0.05). SF-36 scores at the sixth month after surgery were
significantly improved compared with preoperative scores (P<0.001). Preoperative
Physical Component Summary Scale (PCS) and Mental Component Summary Scale (MCS)
scores were negatively associated with extraversion (E score) (B=-0.986 and -0.967,
respectively, both P<0.05). Postoperative PCS and State Anxiety Inventory (SAI)
scores were negatively associated with neuroticism (N score; B=-0.137 and -0.991,
respectively, both P<0.05). Postoperative MCS, SAI, Trait Anxiety Inventory (TAI),
and BAI scores were also negatively associated with the N score (B=-0.367, -0.107,
-0.281, and -0.851, respectively, all P<0.05). The KSS function score at the sixth
month after surgery was negatively associated with TAI and N scores (B=-0.315 and
-0.532, respectively, both P<0.05), but positively associated with the E score
(B=0.215, P<0.05). The postoperative KSS joint score was positively associated
with postoperative PCS (B=0.356, P<0.05). In conclusion, for TKR patients, the
scores used for evaluating recovery of knee function and HRQL after 6 months are
inversely associated with the presence of negative emotions.

Abstract
Transition dynamics and mean shear flow generation in plasma interchange turbulence are explored in a flux-driven system that resembles the plasma edge region. The nonlinear evolution of the interchange mode shows two confinement regimes with different transport levels. Large amplitude oscillations in the phase space of turbulence intensity and mean flow energy are observed and investigated. Both clockwise and counterclockwise oscillations occur during the transition between the two regimes. The Reynolds stress gradients are shown to play a critical role in the generation of mean sheared flows in the edge region. Both the forward and back transitions are simulated self-consistently and a significant hysteresis is found.
