Abstract
Nowadays, breast cancer has become a major killer threatening women health. MET is a receptor tyrosine kinase that upon binding of its ligand, hepatocyte growth factor, activates downstream pathways with diverse cellular functions which are important in occurrence and development of breast cancer. Crizotinib (Cro) is multi-target tyrosine kinase inhibitor targeting ALK gene recombination, MET gene amplification and ROS gene. Although, Cro has ideal treatment of breast cancer, Cro has stronger hepatotoxicity and lacks targeting capacity to tumor cell, which limited Cro to effectively therapy breast cancer. In this study, we develop a novel prodrug micelle through polymerization reaction polymerizing Cro onto the chain to form POEG-b-PCro prodrug micelles, which the drug loading capacity of Cro was significantly increased to improve cumulant of tumor. Pharmacokinetic and biodistribution studies illustrated POEG-b-PCro prodrug micelles had significant effect through improving Cro content in tumor. Meanwhile, antitumor mechanism of POEG-b-PCro prodrug micelles proved POEG-b-PCro prodrug micelles had stronger effect through reducing negative regulatory proteins. POEG-b-PCro prodrug micelles had splendid safety through safety study in vivo to account for POEG-b-PCro prodrug micelles. Therefore, POEG-b-PCro prodrug micelles are a promising drug delivery strategy for reducing toxicity and enhancing efficacy of Cro.

Abstract
Spatially ordered arrangements of spherical colloids are known to exhibit structural colours. The intensity and brilliance of these structural colours typically improve with colloidal monodispersity, low concentrations of point and line defects and with increasing refractive index contrast between the colloids and the embedding medium. Here we show that suspensions of charge stabilised, fluorinated latex particles with low refractive-index contrast to their aqueous background form Wigner crystals with FCC symmetry for volume fractions between 13 and 40%. In reflection they exhibit both strong, almost angle-independent structural colours and sharp, more brilliant Bragg peaks despite the particle polydispersity and bimodal distribution. Simultaneously, these suspensions appear transparent in transmission. Furthermore, binary AB, A2B and A13B type mixtures of these fluorinated and similarly sized polystyrene particles appeared predominantly white but with clear Bragg peaks indicating a CsCl-like BCC structure and more complex crystals. We characterised the suspensions using a combination of reflectivity measurements and small-angle x-ray scattering, complemented by reflectivity modelling.

Abstract
The coronavirus disease 2019 (COVID-19) pandemic caused by severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) has resulted in catastrophic damage worldwide. Accordingly, the development of powerful, safe, easily accessible vaccines with long-term effectiveness is understood as an urgently needed countermeasure against this ongoing pandemic. Guided by this strong promise of using AAVs, we here designed, optimized, and developed an AAV-based vaccines (including AAV-RBD(max), AAV-RBD(wt), AAV-2xRBD, and AAV-3xRBD) that elicit strong immune responses against the RBD domain of the SARS-CoV-2 S protein. These immunogenic responses have proven long-lived, with near peak levels for at least six months in mice. Notably, the sera immunized with AAV-3xRBD vaccine contains powerful neutralizing antibodies against the SARS-CoV-2 pseudovirus. Further evidence proven that potent specific antibodies could also be elicited in canines after vaccination with AAV-3xRBD vaccine.

Abstract
Abstract
Background: Our previous study reported a good efficacy and safety of pyrotinib combined with trastuzumab neoadjuvant treatment in human epidermal growth factor receptor 2 (HER2)-positive breast cancer patients. We further explored the potential biomarkers for the efficacy of pyrotinib combined with trastuzumab neoadjuvant treatment in HER2-positive breast cancer patients. Methods:To date, a total of 162 patients with early-stage breast cancer were enrolled for the neoadjuvant pyrotinib combined with trastuzumab treatment clinical trial (ChiCTR1900022293). By the method of 425 genes next-generation sequencing (NGS), the genomic characteristics of them were evaluated for the potential correlation with postoperative pathological complete response (pCR). Results:. Among the cohort of 162 cases, a total of 43 patients have completed the whole therapy as well as final surgery and acquired qualified sequencing analysis report, and 25 of them achieved total pCR. The most frequently mutated driver genes were TP53 (80%), PIK3CA (46%), ERBB2 (10%), NF1 (8%), NBN (8%), ATRX (8%), respectively. In terms of somatic copy number alterations, the most frequent alterations are gain or amplification of ERBB2 (66%), MYC (24%), CKD12 (14%), CCND1 (12%) and ZNF217 (12%), respectively. The median tumor mutation burden (TMB) was 4.76 mut/Mb (0.00-29.61). Compared with pCR populations, non-pCR populations had higher median TMB but not statistically significant (5.29 vs 3.85 mut/Mb, P=0.141). In addition, the pCR rate of patients with wild-type PIK3CA is significantly higher than that of patients with mutated PIK3CA (80.0% vs 27.8%, P = 0.001), and those with amplified MYC are more likely to achieve pCR (22.2% vs 67.6%, P = 0.023). Conclusions:Preliminary results suggested that HER2-positive breast cancer patients with activating mutations in PIK3CA and amplified MYC are less likely to benefit from pyrotinib combined with trastuzumab neoadjuvant therapy, which need larger sample size to validate.

Abstract
PURPOSE OF REVIEW With cardiovascular disease (CVD) being the top cause of deaths worldwide, it is important to ensure healthy cardiovascular aging through enhanced understanding and prevention of adverse health effects exerted by external factors. This review aims to provide an updated understanding of environmental influences on cardiovascular aging, by summarizing epidemiological and mechanistic evidence for the cardiovascular health impact of major environmental stressors, including air pollution, endocrine-disrupting chemicals (EDCs), metals, and climate change. RECENT FINDINGS Recent studies generally support positive associations of exposure to multiple chemical environmental stressors (air pollution, EDCs, toxic metals) and extreme temperatures with increased risks of cardiovascular mortality and morbidity in the population. Environmental stressors have also been associated with a number of cardiovascular aging-related subclinical changes including biomarkers in the population, which are supported by evidence from relevant experimental studies. The elderly and patients are the most vulnerable demographic groups to majority environmental stressors. Future studies should account for the totality of individuals' exposome in addition to single chemical pollutants or environmental factors. Specific factors most responsible for the observed health effects related to cardiovascular aging remain to be elucidated.

Abstract
Engineering conventional hydrogels with muscle-like anisotropic structures can efficiently increase the fatigue threshold over 1000 J m-2 along the alignment direction; however, the fatigue threshold perpendicular to the alignment is still as low as ≈100-300 J m-2 , making them nonsuitable for those scenarios where isotropic properties are desired. Here, inspired by the distinct structure-properties relationship of heart valves, a simple yet general strategy to engineer conventional hydrogels with unprecedented yet isotropic fatigue resistance, with a record-high fatigue threshold over 1,500 J m-2 along two arbitrary in-plane directions is reported. The two-step process involves the formation of preferentially aligned lamellar micro/nanostructures through a bidirectional freeze-casting process, followed by compression annealing, synergistically contributing to extraordinary resistance to fatigue crack propagation. The study provides a viable means of fabricating soft materials with isotropically extreme properties, thereby unlocking paths to apply these advanced soft materials toward applications including soft robotics, flexible electronics, e-skins, and tissue patches.

Abstract
The introduction of N2 -fixing species into a Eucalyptus plantation resulted in a successful planting system. It is essential to understand the contribution of nitrogen (N) competition and photosynthetic efficiency to plant dry matter yield to shed more light on the growth mechanism of the Eucalyptus/legume system. We compared N competition, photosynthesis and dry matter yield of Eucalyptus urophylla × E. grandis and the N2 -fixing tree species Dalbergia odorifera in intercropping and monoculture systems under different N levels. The photosynthesis of E. urophylla × E. grandis was improved, while that of D. odorifera was inhibited in the intercropping system. Intercropped E. urophylla × E. grandis increased the N utilization and the dry matter yield by 6.57-48.46% and 7.59-97.26%, and decreased those of D. odorifera by 10.21-30.33% and 0.48-13.19%, respectively. Furthermore, N application enhanced the competitive ability of E. urophylla × E. grandis relative to D. odorifera and changed the N contents and chlorophyll synthesis to optimize the photosynthetic structure of both species. Our results reveal Eucalyptus for photosynthesis, N absorption and increasing the growth benefit from the introduction of N2 -fixing species, which hence can be considered to be an effective sustainable management option of Eucalyptus plantations.

Abstract
AIM To develop a nomogram based on computed tomography (CT) texture analysis for the preoperative prediction of visceral pleural invasion in patients with cT1N0M0 lung adenocarcinoma. MATERIALS AND METHODS A dataset of chest CT containing lung nodules was collected from two institutions, and all surgically resected nodules were classified pathologically based on the presence of visceral pleural invasion. Each nodule on the CT image was segmented automatically by artificial-intelligence software and its CT texture features were extracted. The dataset was divided into training and external validation cohorts according to the institution, and a nomogram for predicting visceral pleural invasion was developed and validated. RESULTS Of a total of 313 patients enrolled from two independent institutions, 63 were diagnosed with visceral pleural invasion. Three-dimensional (3D) CT long diameter, skewness, and sphericity, and chronic obstructive pulmonary disease were identified as independent predictors for visceral pleural invasion by multivariable logistic regression. The nomogram based on multivariable logistic regression showed great discriminative ability, as indicated by a C-index of 0.890 (95% confidence interval [CI]: 0.867-0.914) and 0.864 (95% CI: 0.817-0.911) for the training and external validation cohorts, respectively. Additionally, calibration of the nomogram revealed good predictive ability, as indicated by the Brier score (0.108 and 0.100 for the training and external validation cohorts, respectively). CONCLUSIONS A nomogram was developed that could compute the probability of visceral pleural invasion in patients with cT1N0M0 lung adenocarcinoma with good calibration and discrimination. The nomogram has potential as a reliable tool for clinical evaluation and decision-making.

Abstract
OBJECTIVE To analyze the clinical characteristics and factors affecting prognosis in children with severe aplastic anemia (SAA). METHODS Two hundred and five children with SAA treated in our department from January 2008 to April 2018 were selected, and the clinical characteristics and factors affecting prognosis were retrospectively analyzed. RESULTS Among 205 SAA children, the effective rate (CR+PR) at 3, 6 and 12 months after immunosuppressive therapy (IST) treatment was 50.9%, 59.0% and 73.9%, respectively, and 5-year overall survival rate was 93.1%±2.0%. Univariate analysis showed that 5-year overall survival rate of SAA children of spontaneous delivery was higher than that of cesarean section (P=0.039), while multivariate analysis showed that birth way had no significant influence on 5-year overall survival rate (P>0.05). The response rate at 3 months after IST of children with a recent history of decoration before SAA onset was higher than those without history of decoration (P<0.05). CONCLUSION Most of the SAA children can achieve high response rate and overall survival rate. Patients with recent history of home/school decoration may be the factor affecting hematological response after 3 months of IST, but have no influence on long-term overall survival.

Abstract
Hypoxia is a prominent feature of head and neck cancer. However, the oxygen element characteristics of proteins and how they adapt to hypoxia microenvironments of head and neck cancer are still unknown. Human genome sequences and proteins expressed data of head and neck cancer were retrieved from pathology atlas of Human Protein Atlas project. Then compared the oxygen and carbon element contents between proteomes of head and neck cancer and normal oral mucosa-squamous epithelial cells, genome locations, pathways, and functional dissection associated with head and neck cancer were also studied. A total of 902 differentially expressed proteins were observed where the average oxygen content is higher than that of the lowly expressed proteins in head and neck cancer proteins. Further, the average oxygen content of the up regulated proteins was 2.54% higher than other. None of their coding genes were distributed on the Y chromosome. The up regulated proteins were enriched in endocytosis, apoptosis and regulation of actin cytoskeleton. The increased oxygen contents of the highly expressed and the up regulated proteins might be caused by frequent activity of cytoskeleton and adapted to the rapid growth and fast division of the head and neck cancer cells. The oxygen usage bias and key proteins may help us to understand the mechanisms behind head and neck cancer in targeted therapy, which lays a foundation for the application of stoichioproteomics in targeted therapy and provides promise for potential treatments for head and neck cancer.

Abstract
High-accuracy mass measurements of neutron-deficient Yb isotopes have been performed at TRIUMF using TITAN's multiple-reflection time-of-flight mass spectrometer (MR-TOF-MS). For the first time, an MR-TOF-MS was used on line simultaneously as an isobar separator and as a mass spectrometer, extending the measurements to two isotopes further away from stability than otherwise possible. The ground state masses of ^{150,153}Yb and the excitation energy of ^{151}Yb^{m} were measured for the first time. As a result, the persistence of the N=82 shell with almost unmodified shell gap energies is established up to the proton drip line. Furthermore, the puzzling systematics of the h_{11/2}-excited isomeric states of the N=81 isotones are unraveled using state-of-the-art mean field calculations.

Abstract
Objective: To investigate the long-term characteristic changes of virus, immune status, and liver fibrosis markers in human immunodeficiency virus (HIV)/hepatitis C virus (HCV) co-infected patients after receiving direct-antiviral agents (DAAs). Methods: HIV/HCV co-infected patients who visited the Guangzhou Eighth People's Hospital, Guangzhou Medical University from May 2014 to December 2019 were selected as the research subjects. The changes of virological response rate, peripheral blood CD4(+)T lymphocyte level and serological markers of liver fibrosis (APRI score and FIB-4 index) were observed during 144 weeks of follow-up course after the end of DAAs treatment. Kruskal-Wallis test was used for statistical approach. Results: A total of 103 cases were included in the study. There were 87 males (87.5%), with a median age of 44 years. Sustained virological response rate at 12 weeks (SVR12) after DAAs treatment was 97.6%, and the SVR during the entire follow-up period was at least 95.9%. Compared with baseline, CD4(+)T lymphocyte count were significantly increased equally at 12 weeks (Z = -2.283, P = 0.022), 24 weeks (Z = -3.538, P < 0.001), 48 weeks (Z = -3.297, P = 0.001), 96 weeks (Z = -3.562, P < 0.001), and 144 weeks (Z = -2.842, P = 0.004). APRI score (Z = -6.394, P < 0.001) and FIB-4 index (Z = -2.528, P = 0.011) were significantly lower than baseline at week 4 of DAAs treatment, and thereafter remained at a low level, without further declination. Conclusion: HIV/HCV co-infected patients can maintain high SVR for a long time, acquire good immune reconstitution, and significantly improve liver fibrosis after DAAs treatment.

Abstract
The objective of this study was to investigate the impact of protein type (sodium caseinate and pea protein isolate) and protein to sugar beet pectin mixing ratio (5 : 1 and 2 : 1) on complex coacervate formation, as well as the impact of the finishing technology (freeze-drying and spray-drying) for improving the viability of encapsulated Lactobacillus rhamnosus GG (LGG) in complex coacervates during simulated sequential gastrointestinal (GI) digestion. The physicochemical properties of LGG encapsulated microcapsules in liquid and powder form were evaluated. The state diagram and ζ-potential results indicated that pH 3.0 was the optimum pH for coacervate formation in the current systems. Confocal laser scanning microscopy (CLSM), viscoelastic analysis, and Fourier transform infrared spectroscopy (FTIR) confirmed that the gel-like network structure of the complex coacervates was successfully formed between the protein and SBP at pH 3.0 through electrostatic interaction. In terms of physiochemical properties and viability of LGG encapsulated in the microcapsule powder, the drying method played a crucial role on particle size, microstructure and death rate of encapsulated LGG during simulated sequential GI digestion compared to protein type and biopolymer mixing ratio. For example, the microstructure of spray-dried microcapsules exhibited smaller spherical particles with some cavities, whereas the larger particle size of freeze-dried samples showed a porous sponge network structure with larger particle sizes. As a result, spray-dried LGG microcapsules generally had a lower death rate during simulated sequential gastrointestinal digestion compared to their freeze-dried counterparts. Among all samples, spray-dried PPI-SBP microcapsules demonstrated superior performance against cell loss and maintained more than 7.5 log CFU per g viable cells after digestion.

COSMOS next generation - A public knowledge base leveraging chemical and biological data to support the regulatory assessment of chemicals. COMPUTATIONAL TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2021; 19:100175.

Abstract
The COSMOS Database (DB) was originally established to provide reliable data for cosmetics-related chemicals within the COSMOS Project funded as part of the SEURAT-1 Research Initiative. The database has subsequently been maintained and developed further into COSMOS Next Generation (NG), a combination of database and in silico tools, essential components of a knowledge base. COSMOS DB provided a cosmetics inventory as well as other regulatory inventories, accompanied by assessment results and in vitro and in vivo toxicity data. In addition to data content curation, much effort was dedicated to data governance - data authorisation, characterisation of quality, documentation of meta information, and control of data use. Through this effort, COSMOS DB was able to merge and fuse data of various types from different sources. Building on the previous effort, the COSMOS Minimum Inclusion (MINIS) criteria for a toxicity database were further expanded to quantify the reliability of studies. COSMOS NG features multiple fingerprints for analysing structure similarity, and new tools to calculate molecular properties and screen chemicals with endpoint-related public profilers, such as DNA and protein binders, liver alerts and genotoxic alerts. The publicly available COSMOS NG enables users to compile information and execute analyses such as category formation and read-across. This paper provides a step-by-step guided workflow for a simple read-across case, starting from a target structure and culminating in an estimation of a NOAEL confidence interval. Given its strong technical foundation, inclusion of quality-reviewed data, and provision of tools designed to facilitate communication between users, COSMOS NG is a first step towards building a toxicological knowledge hub leveraging many public data systems for chemical safety evaluation. We continue to monitor the feedback from the user community at support@mn-am.com.

Abstract
Nature builds biological materials from limited ingredients, however, with unparalleled mechanical performances compared to artificial materials, by harnessing inherent structures across multi-length-scales. In contrast, synthetic material design overwhelmingly focuses on developing new compounds, and fails to reproduce the mechanical properties of natural counterparts, such as fatigue resistance. Here, a simple yet general strategy to engineer conventional hydrogels with a more than 100-fold increase in fatigue thresholds is reported. This strategy is proven to be universally applicable to various species of hydrogel materials, including polysaccharides (i.e., alginate, cellulose), proteins (i.e., gelatin), synthetic polymers (i.e., poly(vinyl alcohol)s), as well as corresponding polymer composites. These fatigue-resistant hydrogels exhibit a record-high fatigue threshold over most synthetic soft materials, making them low-cost, high-performance, and durable alternatives to soft materials used in those circumstances including robotics, artificial muscles, etc.

Abstract
BACKGROUND Craniocerebral trauma is a common neurosurgical disease. In recent years, there has been a significant increase in craniocerebral injuries caused by accidental injuries of construction workers. We aimed to analyze the effect of International Classification of functioning, disability and health (ICF) concept rehabilitation training on the recovery of patients (construction workers) with craniocerebral trauma. METHODS A total of 142 patients with craniocerebral trauma from construction sites were randomly divided into two groups. The control group (n=71) received routine rehabilitation training, and the ICF group (n=71) received ICF concept rehabilitation training. Before and after rehabilitation training, the NIHSS was used to evaluate neurological function, the MMSE was used to evaluate cognitive function, the FMA method was used to evaluate limb motor ability, the BI index was used to evaluate self-care ability, and the ICF scale was used to evaluate the rehabilitation outcome. RESULTS There were no significant differences in general information and NIHSS, MMSE, FMA, and BI scores before rehabilitation training between the control and ICF groups. After rehabilitation training, NIHSS scores decreased significantly, while MMSE, FMA, and BI scores increased significantly compared with the control group. CONCLUSIONS ICF concept rehabilitation training significantly improved neurological function and cognitive function, enhanced the motor function of limbs, improved self-care ability, and led to a better rehabilitation outcome of patients with craniocerebral trauma.
