Abstract
Observational studies in adults suggest nasal methicillin-resistant Staphylococcus aureus (MRSA) swabs have a high negative predictive value (NPV) for ruling out MRSA pneumonia, however, pediatric data are limited. This retrospective study of 505 pediatric patients found a 99.8% NPV among children with suspected respiratory infections.

Abstract
To compare different rat models of sepsis at different time points, based on pulmonary or extrapulmonary injury mechanisms, to identify a model which is more stable and reproducible to cause sepsis-associated acute lung injury (ALI). Adult male Sprague-Dawley rats were subjected to (1) cecal ligation and puncture (CLP) with single (CLP1 group) or two repeated through-and-through punctures (CLP2 group); (2) tail vein injection with lipopolysaccharide (LPS) of 10mg/kg (IV-LPS10 group) or 20 mg/kg (IV-LPS20 group); (3) intratracheal instillation with LPS of 10mg/kg (IT-LPS10 group) or 20mg/kg (IT-LPS20 group). Each of the model groups had a sham group. 7-day survival rates of each group were observed (n=15 for each group). Moreover, three time points were set for additional experimental studying in each model group: 4 hours, 24 hours and 48 hours after modeling (every time point, n=8 for each group). Rats were sacrificed to collect BALF and lung tissue samples at different time points for detection of IL-6, TNF-alpha, total protein concentration in BALF and MPO activity, HMGB1 protein expression in lung tissues, as well as the histopathological changes of lung tissues. More than 50 % of the rats died within 7 days in each model group, except for the IT-LPS10 group. In contrast, the mortality rates in the two IV-LPS groups as well as the IT-LPS20 group were significantly higher than that in IT-LPS10 group. Rats received LPS by intratracheal instillation exhibited evident histopathological changes and inflammatory exudation in the lung, but there was no evidence of lung injury in CLP and IV-LPS groups. Rat model of intratracheal instillation with LPS proved to be a more stable and reproducible animal model to cause sepsis-associated ALI than the extrapulmonary models of sepsis.

Abstract
PURPOSE Radiation dermatitis (RD) is a frequently occurring adverse reaction during radiotherapy in cancer patients. While the use of topical corticosteroids (TCs) is common for the treatment of RD, its role in preventing severe reactions remains unclear. This systematic review and meta-analysis aim to evaluate the evidence on the use of TCs as prophylaxis of RD. METHODS A systematic search was conducted using OVID MedLine, Embase, and Cochrane databases (between 1946 and 2023) to identify studies examining TC use in the prevention of severe RD. Statistical analysis was completed using RevMan 5.4 to calculate pooled effect sizes and 95% confidence intervals. Forest plots were then developed using a random effects model. RESULTS Ten RCTs with a total of 1041 patients met the inclusion criteria. Six studies reported on mometasone furoate (MF) and four studies reported on betamethasone. Both TCs were associated with a significant improvement in the prevention of moist desquamation [OR = 0.34, 95% CI [0.25, 0.47], p < 0.00001], but betamethasone was found to be more effective than MF [OR = 0.29, 95% CI [0.18, 0.46], p < 0.00001 and OR = 0.39, 95% CI [0.25, 0.61], p < 0.0001, respectively]. A similar finding was seen in reducing the development of grade 2 or higher RD according to the Radiation Therapy Oncology Group scale. CONCLUSIONS The current evidence supports the use of TCs in preventing severe reactions of RD. Both MF and betamethasone were found to be effective; however, betamethasone, a higher potency TC, is more effective despite MF being more commonly reported in literature.

Abstract
DNA polymerases are the enzymatic catalysts that synthesize DNA during DNA replication and repair. Kinetic studies and x-ray crystallography have uncovered the overall kinetic pathway and led to a two-metal-ion dependent catalytic mechanism. Diffusion-based time-resolved crystallography has permitted the visualization of the catalytic reaction at atomic resolution and made it possible to capture transient events and metal ion binding that have eluded static polymerase structures. This review discusses past static structures and recent time-resolved structures that emphasize the crucial importance of primer alignment and different metal ions binding during catalysis and substrate discrimination.

Abstract
Abstract
Background: Chimeric antigen receptor (CAR) T cell therapy has achieved unprecedented success in treating hematologic malignancies but still struggles in the context of solid tumors. The challenges of effective CAR-T cell therapy for solid tumors are multifaceted including 1) physical barriers that limit T cell infiltration; 2) tumor heterogeneity and antigen escape leading to resistance to therapy; 3) immunosuppressive tumor microenvironment (TME) dampening T cell function. As a novel modality for cancer therapy, oncolytic virus (OV) can be engineered to overcome the limitations of CAR-T therapy in solid tumor. Here we developed a new-generation of oncolytic herpes simplex virus (oHSV) to enable clinically approved CD19 CAR-T for solid tumor therapy.
Methods: oHSV MVR-T7011 (T7011) was genetically engineered to drive ectopic expression of the extracellular domain of CD19, the blood tumor antigen, on solid tumor cell surface upon viral infection. In addition, multiple payloads, CCL5, IL-12, and anti-PD-1 antibody were introduced into T7011 to modulate the TME. Payload expression was detected both in vitro and in vivo. Co-culture studies were performed to test the cell-killing activity of CD19 CAR-T combined with T7011. Antitumor activities of T7011 administrated via intratumoral (IT) or intraperitoneal (IP) in combination with CD19 CAR-T cells were assessed in immunodeficient and immunocompetent mice.
Results: The in vitro studies indicated that the expression of CD19 on tumor cell surface was detected as early as 4 hours post infection (hpi) and retained for at least 96 hours in the T7011-infected cells. In mouse study showed that the CD19 expression on tumor cells was detected as early as 8 hpi and lasted for 20 days when T7011 was injected via IT in immunodeficient mice. The payload of CCL5, IL-12, and anti-PD-1 antibody showed a similar expression pattern as CD19. Co-culture studies showed that T7011 infection enhanced cell-killing activity of CD19 CAR-T but the virus had no effect on viability and proliferation of CAR-T cell itself, which concludes that T7011 does not dampen the CAR-T function as its combination treatment. The in vivo efficacy studies demonstrated that IT and IP administration of T7011, rather than MVR-T3011 virus which lacks CD19, specifically promoted CD19 CAR-T anti-solid tumor activities in both immunodeficient and immunocompetent mice.
Conclusions: The new-generation of HSV oncolytic virus T7011 expressing the targetable CD19 antigen on tumor surface enables the CD19 CAR-T for solid tumor cell treatment as a combination therapy. In addition, T7011 also carries multi-immunomodulators further to enhance antitumor efficacy by reinvigorating the infiltrated CAR-T cells and reversing the immunosuppressive TME. T7011 is expected to be a promising combinational therapy with CD19-specific CAR-T cells enabling effective cell therapy against multiple solid tumors.

Abstract
BACKGROUND Youth with cystic fibrosis (CF) and pulmonary exacerbation (PEx) often experience weight loss, then rapid weight gain. Little is known about body composition and its relationship to functional outcomes during this critical period. METHODS Twenty CF youth experiencing PEx were assessed on the day following admission and 7-17 days later at discharge for body mass index (BMI), fat mass index (FMI), lean mass index (LMI), skeletal muscle mass index (SMMI), and functional measures: percent predicted forced expiratory volume in 1 second (FEV1) (ppFEV1), maximal inspiratory and expiratory pressures (MIPs and MEPs), and handgrip strength (HGS). Changes from admission to discharge and correlations among body composition indices and functional measures at both times are reported. RESULTS Upon admission, participant BMI percentile and ppFEV1 varied from 2 to 97 and 29 to 113, respectively. Thirteen had an LMI below the 25th percentile and nine had a percent body fat above the 75th percentile. BMI and FMI increased significantly (p = 0.03, 0.003) during hospitalization. LMI and SMMI did not change. FEV1 and MIPS increased (p = 0.0003, 0.007), independent of weight gain, during treatment. HGS did not improve. CONCLUSIONS Many youth with CF, independent of BMI, frequently carried a small muscle mass and disproportionate fat at the time of PEx. During hospital treatment, weight gain largely represented fat deposition; muscle mass and strength did not improve. A need for trials of interventions designed to augment muscle mass and function, and limit fat mass accretion, at the time of PEx is suggested by these observations.

Abstract
BACKGROUND Chronic obstructive pulmonary disease (COPD) is a complex disease characterized by limited airflow and is influenced by genetic and environmental factors. The purpose of this study was to investigate the effects of gene polymorphisms in MIR5708 and MIR1208 on COPD risk. METHODS Four single nucleotide polymorphisms (SNPs) in MIR5708 (rs6473227 and rs16907751) and MIR1208 (rs2608029 and rs13280095) were selected and genotyped among 315 COPD patients and 314 healthy controls using the Agena MassARRAY platform. SPSS 18.0 was used for statistical analysis and data processing. Odds ratios (ORs) and 95% confidence intervals (CIs) were calculated to assess the association between genetic variants of MIR1208 and MIR5708 and COPD risk. RESULTS The results suggested that rs16907751 variants in MIR5708 contributed to an increased susceptibility to COPD in the allelic (P = 0.001), co-dominant (homozygous) (P = 0.001), dominant (P = 0.017), recessive (P = 0.002), and additive (P = 0.002) models. The effects of MIR5708 and MIR1208 gene polymorphisms on the risk of COPD were age-, sex-, smoking status-, and BMI-related. Furthermore, the C-A and G-A haplotypes of rs2608029 and rs13280095 in MIR1208 were identified as risk factors for COPD in the population over 70 years (P = 0.029) and in women (P = 0.049), respectively. Finally, significant associations between rs16907751genotypes with pulse rate and forced expiratory volume in 1 s were found among COPD patients. CONCLUSION Genetic polymorphisms in MIR5708 and MIR1208 are associated with increased risk of COPD in China.

Abstract
Postoperative opioid use following gynecologic surgery may be necessary for effective treatment of pain; however, it can result in significant side effects, adverse reactions, and negative health consequences, including prolonged problematic use. Surgeons and healthcare providers of patients recovering from gynecologic procedures should be aware of effective strategies that can decrease the need for opioid use, while providing high-quality pain management. These include adherence to Enhanced Recovery After Surgery Protocols, particularly the use of multimodal analgesia management. When prescribing opioids, providers should adhere to responsible prescribing practices to minimize the risk of inappropriate and/or long-term opioid use.

Abstract
Abstract
BACKGROUND
Medulloblastoma (MB) is the most common pediatric brain tumor. MB can be dividing into 4 genetically distinct subgroups (Sonic Hedgehog (SHH), Wingless (WNT), Group 3, and Group 4). Most patients receive radiation and cisplatin backbone therapy. SHH and Group3 patients demonstrate poor prognosis, especially in cases of MYC amplification or p53 mutation. Given the continued reliance on DNA damage therapies, and our groups previous findings that YB1 regulates IGF2 transcription in SHH MB, we chose to investigate the role of YB1 in the DNA damage response and we performed RIPseq to understand mRNAs regulated by YB1 that may be targeted as novel therapeutics.
METHODS
Cell lines include primary MBCs derived from NeuroD2-SmoA1 SHH mice, ONS-76 human SHH, Daoy human SHH, D341 and D425 Human Group 3. YB1 overexpression or knockdown followed by radiation and assessment of yH2AX (a marker of DNA de-condensation following damage), Comet assay (a marker of physical damage), and proliferation time courses were used to assess effects of YB1 modulation on radiation response. RIPseq and YB1 knockdown were used to assess the effects of YB1 on PLXND1 levels. Scratch assay and western blotting of EMT markers were used to assess effects of PLXND1 silencing on migration.
RESULTS
(Radiation Studies) Overexpression of YB1 in primary MBCs followed by allograft into BL6 mice results in decreased overall survival. YB1 silencing followed by radiation results in faster resolution of yH2AX, faster resolution of damage, and lack of pRPA32 accumulation. YB1 silencing sensitizes cells to radiation resulting in substantial decreases in proliferation. (RNA Binding Protein Studies) YB1 binds and positively regulates PLXND1 translation. Silencing PLXND1 results in decreased migration and EMT mark expression.
CONCLUSIONS
YB1 drives a more error prone non-homologous End-Joining based mechanism of repair and binds and regulates PLXND1 post-transcriptionally. PLXND1 drives a migratory phenotype in SHH MB.

Abstract
Objective: To explore the influencing factors of health-related quality of life (HRQoL) in patients with knee osteoarthritis, and to analyze the non-surgical treatment of knee osteoarthritis. Methods: Demographic variables, treatment modalities, imaging data, and 12-item short form health survey (SF-12) scores of patients with knee osteoarthritis in orthopedic outpatient departments of five hospitals in Beijing from December 2017 to November 2018 were collected to analyze influencing factors of HRQoL and non-surgical treatment. Results: A total of 2 034 patients were included. There were 530 males (26.1%) and 1 504 females (73.9%), with a mean age of (59.17±10.22) years. In terms of physical quality of life, female patients with knee osteoarthritis had lower physical components summary (PCS) compared with male patients (β=-0.521, P=0.036); patients aged ≥64 years had lower PCS than those aged<55 years (β=-0.636, P=0.026). Patients with an education of more than 12 years had higher PCS than those with less than 10 years (β=1.063, P<0.001). Compared to patients with mild clinical symptoms, the PCS of patients with moderate clinical symptoms was lower (β=-0.860, P=0.002), while the PCS of those with severe clinical symptoms was much lower (β=-1.126, P<0.001). Patients treated with combination therapy had higher PCS than untreated patients (β=0.731, P=0.005). In terms of mental quality of life, compared to patients engaged in sedentary work, the mental components summary (MCS) of patients engaged in mild manual labor jobs was lower (β=-0.712, P=0.015); Compared to patients with a Charson comorbidity index of 0, patients with a Charlson comorbidity index ≥ 2 had lower MCS (β=-1.183, P=0.007). In the past 12 months, 648 (31.9%), 143 (7.0%), 406 (20.0%), 680 (33.4%), 343 (16.9%), 681 (33.5%), 170 (8.4%) patients had used non-steroid anti-inflammatory drugs (NSAIDs), acetaminophen, glucosamine/chondroitin formulations, physical therapy, articular cavity puncture injection, traditional Chinese medicine treatment and exercise therapy, respectively. Total of 451 patients (22.2%) received monotherapy and 889 patients (43.7%) received combination therapy. Conclusions: The major non-surgical treatment methods for patients with knee osteoarthritis in Beijing are NSAIDs, physiotherapy and traditional Chinese medicine. Combination therapy is used more frequently than monotherapy. Physical quality of life is related to gender, age, education, severity of symptoms and treatment, while mental quality of life is related to occupational labor and comorbidities.

Abstract
Two different types of desaturations are employed by iron- and 2-oxoglutarate-dependent (Fe/2OG) enzymes to construct vinyl isonitrile and isocyanoacrylate moieties found in isonitrile-containing natural products. A substrate-bound protein structure reveals a plausible strategy to affect desaturation and hints at substrate promiscuity of these enzymes. Analogs are synthesized and used as mechanistic probes to validate structural observations. Instead of proceeding through hydroxylated intermediate as previously proposed, a plausible carbocation species is utilized to trigger C=C bond installation. These Fe/2OG enzymes can also accommodate analogs with opposite chirality and different functional groups including isonitrile-(D)-tyrosine, N-formyl tyrosine, and phloretic acid, while maintaining the reaction selectivity. While canonical oxygen-rebound pathway has been utilized by several Fe/2OG enzymes, insights into the desaturation process remain to be elucidated. Here, the authors suggest that a carbocation might be deployed to enable chemically divergent desaturations through decarboxylation and deprotonation.

Abstract
This article has been retracted: please see Elsevier Policy on Article Withdrawal (https://www.elsevier.com/about/our-business/policies/article-withdrawal). The article is a duplicate of a paper that has already been published in Medicine, 97 (2018) e11849 https://doi.org/10.1097/MD.0000000000011849. Redundant publications overweigh the relative importance of published findings and distort the academic record of the authors. One of the conditions of submission of a paper for publication is therefore that authors declare explicitly that the paper has not been previously published and is not under consideration for publication elsewhere. As such this article represents a misuse of the scientific publishing system. The scientific community takes a very strong view on this matter and apologies are offered to readers of the journal that this was not detected during the submission process.

Abstract
Piglet mortality is an economically important complex trait that impacts sow prolificacy. Genetic analyses for piglet mortality at weaning have been reported in dozens of studies, but not for piglet mortality at birth. In this study, we used multi-breed data sets from Yorkshire, Landrace, and Duroc sows to characterize the genetic fundamentals of piglet mortality at birth. The heritabilities from parity I to III were estimated to be 0.0630, 0.1031, and 0.1140 respectively. By using a combined strategy, a total of 21 SNPs were detected in three parities, of which six were observed in parity I, five in parity II and 10 in parity III. Genome annotation revealed that these SNPs were harbored within or close to 19 candidate genes. The candidate genes were found to associate with the reproductive system and embryonic development in the tissue expression database, which are reasonably related to piglet mortality. These findings are expected to provide much information for understanding the genetic and genomic fundamentals of farrowing mortality.

Abstract
Context The increased number of male dairy origin calves in Ireland due to the abolition of European Union milk quotas is a potential resource for the beef industry. Rearing these animals as bulls rather than steers is more efficient from a production perspective. Ensuring satisfactory quality of bull beef from dairy origin is essential. Aim To determine the effect of two production systems and three muscle types on physico-chemical characteristics and fatty acid (FA) profile of beef from Holstein-Friesian (HF) bulls. Methods Thirty HF bulls were equally assigned to two production systems, namely, slaughter at under 16 months of age or slaughter at 19 months of age. Longissimus thoracis (LT), Semitendinosus (ST) and Gluteus medius (GM) muscles were excised post-slaughter for determination of pH, colour, Warner–Bratzler (WB) variables, cook loss, chemical composition [intramuscular fat (IMF), moisture, protein, ash], collagen characteristics and FA profile. Results WB variables and cook loss after 14 days postmortem ageing, and insoluble and total collagen contents were higher, while IMF content, redness and saturation at 24 h post-blooming were lower for muscles from the 19-month production system. Muscles from the under 16-month production system had a higher saturated fatty acid (SFA) proportion and n-6:n-3 polyunsaturated fatty acid (PUFA) ratio, while muscle from the 19-month production system had a higher PUFA proportion, n-3 PUFA proportion and PUFA:SFA ratio. The GM muscle had the lowest L* value, followed by LT and ST. Yellowness, saturation and hue angle were greater in ST. LT had lower WB variables, cook loss, moisture, and a higher IMF content than ST and GM. The PUFA proportion and PUFA:SFA ratio were highest in ST, followed by GM and LT. IMF, total FA, SFA and monounsaturated fatty acid (MUFA) concentrations were higher in LT from the under 16-month production system bulls (the interaction). Conclusions Beef from the under 16-month production system compared with beef from the 19-month production system, and LT compared with ST and GM muscles had better quality characteristics. Implications Dairy bulls can produce beef of acceptable quality. The findings will guide selection of the combination of production system and muscle type most appropriate to specific market requirements.

Abstract
Purpose: Parental education regarding the importance of toothbrushing and how to brush children's teeth is a key factor influencing pediatric oral health and You Tube videos have become a popular source of health information. The purpose of this study was to examine the descriptive features of the 100 most frequently viewed English-language YouTube toothbrushing videos and evaluate their usefulness relative to professional guidelines.Methods: A structured YouTube web search identified the 100 most frequently viewed toothbrushing videos during a six-month period (10/1/17 - 4/30/18). Two independent evaluators assessed each video for consistency with professional recommendations using a priori criteria. Each video was also assessed for descriptive characteristics, user engagement, and content. Comparative analyses by video source (health care professionals, commercial, and independent media) were performed, and an exploratory regression model was used to test the relationship between video characteristics and usefulness for parent education.Results: The top 100 YouTube videos were most often posted by independent media outlets (78%), targeted toward children (70%), and less than 2 minutes long (56%). Few videos aligned with professional recommendations regarding toothbrushing frequency (38%), toothbrushing duration (24%), amount of toothpaste (21%), fluoride toothpaste use (19%), post-brushing behavior (10%), toothbrush selection (4%), and toothbrush replacement (3%). A stepwise bidirectional regression model found that videos posted by health care professionals were significantly more likely to contain recommendations consistent with professional recommendations compared with other upload sources.Conclusion: The most frequently viewed toothbrushing videos were not uploaded to the Internet by health care professionals. Videos uploaded by health care professionals contained significantly higher counts of professional recommendations however, they differed in audio and visual format and production style compared to those from commercial and independent media sources.

Abstract
Climatic factors play an essential role in the growth of tree ring width. In this study, we aimed to evaluate the correlation between climatic variables and tree-ring growth characteristics of Pinus sibirica in Altai mountains, northwestern China. This study being is first of its kind on climate growth analysis of Pinus sibirica in northwestern China. The study showed great potential to understand the species growing under the specific climatic conditions. Total of 70 tree cores collected from three sites in the sampling area, out of which 63 tree cores considered for this study. The effect of climatic variables which was studied include precipitation, temperature and PDSI. Our results showed that Tree Ring Width chronology has a significantly positive correlation with the late winter (March) temperature and significant negative correlation with the July temperatures. A significant correlation was observed with the late summer precipitation whereas no significant relation found with the Palmer Drought Severity Index. These significant correlations with temperature and precipitation suggested that this tree species had the potential for the reconstruction of the past climate in the area.

Abstract
The mutations are genetic changes in the genome sequences and have a significant role in biotechnology, genetics, and molecular biology even to find out the genome sequences of a cell DNA along with the viral RNA sequencing. The mutations are the alterations in DNA that may be natural or spontaneous and induced due to biochemical reactions or radiations which damage cell DNA. There is another cause of mutations which is known as transposons or jumping genes which can change their position in the genome during meiosis or DNA replication. The transposable elements can induce by self in the genome due to cellular and molecular mechanisms including hypermutation which caused the localization of transposable elements to move within the genome. The use of induced mutations for studying the mutagenesis in crop plants is very common as well as a promising method for screening crop plants with new and enhanced traits for the improvement of yield and production. The utilization of insertional mutations through transposons or jumping genes usually generates stable mutant alleles which are mostly tagged for the presence or absence of jumping genes or transposable elements. The transposable elements may be used for the identification of mutated genes in crop plants and even for the stable insertion of transposable elements in mutated crop plants. The guanine nucleotide-binding (GTP) proteins have an important role in inducing tolerance in rice plants to combat abiotic stress conditions.

Abstract
Abstract
Background: Limited success has been reported with intravenous delivery of oncolytic viruses because of dilution of viruses in the blood volume, rapid clearance of viral particles and sequestration in non-target organs. We have reported construction of MVR-T3011, a recombinant oncolytic herpes virus embodies immunotherapeutic genes encoding IL-12 and anti-PD-1 antibody. Intratumoral Injection of MVR-T3011 has entered into clinical stage for the study of its safety and preliminary efficacy. Here we propose systemic delivery of MVR-T3011 by intravenous (IV) injection to treat tumor types that are not easily accessible by local injection.
Methods: The pharmacological activity, safety and biodistribution of MVR-T3011 by intravenous injection have been studied in immune deficient and competent mouse model.
Results: (i) In immune deficient mice, MVR-T3011 is enriched in tumor following tail vein injection. MVR-T3011 inhibits tumor growth of A549 xenograft. (ii) In immune competent mice, MVR-T1013L, the virus backbone carries a reporter gene encodes luciferase was enriched in upper abdomen and thorax 24hr following IV injection. (iii) IV administration of mouse surrogate oncolytic virus MVR-T3855 extended survival of mice in B16-F10 mouse melanoma lung metastasis model, LLC mouse orthotopic lung cancer model and H22 mouse orthotopic hepatocarcinoma model significantly. (iv) IV administration of MVR-T3855 delayed the onset of peritoneal effusion in H22 mouse hepatocarcinoma model significantly. (v) The biodistribution studies showed: following IV injection, tumor viral DNA reached peak level at 24hr, and dropped to baseline at 48hr; Subsequent injection showed similar patterns with lower peak levels. Consistent virus DNA level in the blood was detected without spike of viral DNA in other tissues probably due to non-complete virus genome circulating following virus clearance. Both IL-12 and anti-PD-1 antibody were detected in tissue and/or blood with low level 24hr following injection.
Conclusions: MVR-T3011 is a suitable herpes oncolytic virus agent for intravenous injection through studies of pharmacological activity, safety and biodistribution. The significant finding reported in this article is clinical potential of herpes oncolytic virus for extensive metastatic tumors.

Abstract
AIM Colorectal cancer is predominantly a disease of the elderly and up to 30% of these patients will present as an emergency. We compared the outcomes of 'elderly' patients presenting to our unit with a colorectal cancer emergency over a 10-year period with those of a 'younger' cohort. METHODS A single centre retrospective review of colorectal cancer emergencies between 1 April 2007 and 1 April 2017 was performed. Patients were separated into two cohorts: 'young' (< 75 years) and 'elderly' (≥ 75 years). Data collected included demographics, disease status, treatment and outcomes. RESULTS A total of 341 patients (< 75 years: n = 154; ≥ 75 years: n = 187) presented as a colorectal cancer emergency. Significantly fewer 'elderly' patients underwent curative surgical procedures (72% vs 49%, P < 0.0001) or received adjuvant chemotherapy (56% vs 21%, P < 0.0001). 'Elderly' patients had significantly more postoperative cardio-respiratory complications (7% vs 36%, P < 0.0001), but despite this there was no significant difference in 30-day mortality (7% vs 12%) and survival rates at 1 year (75% vs 74%) or 3 years (56% vs 49%). Elderly patients treated with best supportive care had a median overall survival of just 62 (range 1-955) days. CONCLUSION Patients ≥ 75 years presenting as a colorectal cancer emergency were significantly less likely to undergo emergency curative surgery or receive adjuvant chemotherapy than those < 75 years. However, the 30-day mortality, 1- and 3-year survival rates for patients undergoing curative surgery were comparable.

Abstract
Abstract
Background
With demographic and epidemiologic transitions, China has become home to the greatest number of obese individuals in the world. Effective policy intervention requires a contemporary assessment of obesity across broad socio-demographic subgroups.
Purpose
We aim to assess the prevalence of overall and abdominal obesity by socio-demographic characteristics and the associations of these characteristics with obesity in China.
Methods
Using the data of 2.7-million community-dwelling participants aged 35–75 years in the China PEACE Million Persons Project, a nationwide cross-sectional screening project from 2014 to 2018, we calculated the prevalence of overall and abdominal obesity based on national guideline definitions (body mass index ≥28 kg/m2, waist circumference ≥85/90 cm for women/men). We examined 12 available socio-demographic variables that are potentially associated with obesity, in addition to self-reported co-morbidities, and quantified the associations of these socio-demographic characteristics with obesity using multivariable mixed models.
Results
The prevalence of overall and abdominal obesity were 15.8% and 37.6% in women and 15.0% and 36.3% in men (Figure). Compared to individuals with normal weight, those with overall obesity had a higher prevalence of hypertension, dyslipidemia, and diabetes (in women: by 30.4, 16.1, and 6.0 percent points; in men, by 29.9, 31.2, and 5.8 percent points). A similar pattern was observed with abdominal obesity. In women, those aged 55–64 years constituted the largest age group with overall and abdominal obesity (33.7% and 35.0%), while in men, those aged 45–54 and 55–64 years constituted the largest age group with overall obesity (30.4%) and abdominal obesity (30.5%), respectively. Older women were at substantially higher risk for obesity (e.g., adjusted relative risk [95% CI] of women aged 65–75 vs. 35–44 years: 1.29 [1.27–1.31] for overall obesity and 1.76 [1.74–1.77] for abdominal obesity) while older men were not. Higher education was associated with lower risk in women (e.g., those with college or university education vs. less than primary school: 0.47 [0.46–0.48] for overall obesity and 0.61 [0.60–0.62] for abdominal obesity) but higher risk in men (1.07 [1.05–1.10] and 1.17 [1.16–1.19]). In both women and men, current smoking was associated with lower risk for obesity, and current drinking was associated with higher risk, but the magnitude of associations was smaller in women than men.
Conclusions
In China, over one in seven individuals meet criteria for overall obesity, and one in three for abdominal obesity. Wide variation exists across socio-demographic subgroups. The associations of age and education with obesity are significant and differ by sex. Understanding obesity in contemporary China has broad domestic policy implications and provides a valuable international reference.

Abstract
Manned space exploration was initiated in China in 1992, and substantial progress has been made. The next step is to build the Chinese Space Station (CSS), which is planned to be launched in 2020. The CSS will provide an on-orbit laboratory for experimental studies including space radiation research. The health risk of space radiation, especially carcinogenesis, is a major concern for long-term space exploration. Establishing a risk assessment system suitable for Chinese astronauts and developing effective countermeasures are major tasks for Chinese space radiobiologists. The Institute of Space Life Sciences, Soochow University has focused on these topics for years. We established cancer models with low-dose-rate exposure of alpha particles, and elucidated a microRNA-TGFβ network regulating bystander effects and a lncRNA-cytoskeleton network regulating genomic instability induced by ionising radiation. We also confirmed the radioresistance of quiescent cells, which inspires a potential strategy to improve individual radioresistance during long-term space travel. However, we believe that a multi-disciplinary strategy must be developed to protect astronauts from highly energised space radiation.

Abstract
Appropriate cell sources, bioactive factors and biomaterials for generation of functional and integrated annulus fibrosus (AF) tissue analogues are still an unmet need. In the present study, the AF cell markers, collagen type I, cluster of differentiation 146 (CD146), mohawk (MKX) and smooth muscle protein 22α (SM22α) were found to be suitable indicators of functional AF cell induction. In vitro 2D culture of human AF cells showed that transforming growth factor β1 (TGF-β1) upregulated the expression of the functional AF markers and increased cell contractility, indicating that TGF-β1-pre-treated AF cells were an appropriate cell source for AF tissue regeneration. Furthermore, a tissue engineered construct, composed of polyurethane (PU) scaffold with a TGF-β1-supplemented collagen type I hydrogel and human AF cells, was evaluated with in vitro 3D culture and ex vivo preclinical bioreactor-loaded organ culture models. The collagen type I hydrogel helped maintaining the AF functional phenotype. TGF-β1 supplement within the collagen I hydrogel further promoted cell proliferation and matrix production of AF cells within in vitro 3D culture. In the ex vivo IVD organ culture model with physiologically relevant mechanical loading, TGF-β1 supplement in the transplanted constructs induced the functional AF cell phenotype and enhanced collagen matrix synthesis. In conclusion, TGF-β1-containing collagen-PU constructs can induce the functional cell phenotype of human AF cells in vitro and in situ. This combined cellular, biomaterial and bioactive agent therapy has a great potential for AF tissue regeneration and rupture repair.

Abstract
BACKGROUND Inflammatory bowel disease is a chronic immunoinflammatory disease of the gastrointestinal tract. Piperine, an alkaloid, has been reported to possess antioxidant, anti-inflammatory, antiapoptotic, and antiulcer potential. AIM To elucidate the plausible mechanisms of action of piperine on experimental trinitrobenzenesufonic acid (TNBS)-induced colitis by assessing various biochemical, molecular, histological, and ultrastructural modifications. METHODS Colitis was induced in male Sprague-Dawley rats via intrarectal instillation of TNBS. Then, the rats were treated with piperine (10, 20, and 40 mg/kg, p.o.) for 14 days. RESULTS TNBS induced significant (p < 0.05) colonic damage, which was assessed by disease activity index, macroscopic score, and stool consistency. The administration of piperine (20 and 40 mg/kg) significantly inhibited (p < 0.05) these damages. Treatments with piperine (20 and 40 mg/kg) notably inhibited (p < 0.05) the TNBS-induced elevation of oxido-nitrosative stress (superoxide dismutase, glutathione, malondialdehyde, and nitric oxide), 5-hydroxytryptamine, and hydroxyproline content in the colon. Furthermore, colonic inducible nitric oxide synthase (iNOs), tumor necrosis factor-alpha (TNF-α), interleukin (IL)-1β, IL-6, interferon-gamma, and cyclooxygenase-2 (COX-2) messenger RNA (mRNA) expressions were upregulated after TNBS instillation and piperine (20 and 40 mg/kg) significantly attenuated (p < 0.05) these elevated mRNA expressions. TNBS decreased the expressions of tight junction (TJ) protein (claudin-1, occludin, and zonula occludens-1 (ZO-1)) and increased the expressions of proapoptotic (caspase-1) protein. These expressions were markedly inhibited (p < 0.05) by piperine treatment. Histological and ultrastructural studies of transmission electron microscopy suggested that piperine significantly ameliorated (p < 0.05) TNBS-induced colonic aberrations. CONCLUSION Piperine ameliorated the progression of TNBS-induced colitis by modulating the nuclear factor of kappa light polypeptide gene enhancer in B-cells inhibitor-alpha/nuclear factor-kappa B signaling pathway, thus inhibiting the overexpression of proinflammatory cytokines (TNF-α and IL's), COX-2, iNOs, oxido-nitrosative stress, and proapoptotic proteins (caspase-1) that may improve the expression of TJ protein (claudin-1, occludin, and ZO-1).

Abstract
92 Background: Systemic administration of checkpoint inhibitors alone and especially concurrent with intratumoral administration of oncolytic herpes simplex viruses (oHSV) have a major impact on cancer therapy marred by rare failures of healthy organs. Methods: We constructed 3 recombinant oHSVs expressing no immunomodulatory genes (T1 series), murine or human IL-12 (T2 series) and murine or human IL-12 and anti-PD-1 antibody (T3 series). We compared 1) the oncolytic effects of a single or multiple intratumoral injection(s) of T1, T2 and T3 series oHSVs, 2) the effectiveness of intratumoral injection of T3 oHSV with systemic administration of anti PD-1 ab and IL12 alone or in combinations with T1. Results: Insertion of gene encoding PD-1 Ab significantly augmented the oncolytic activity of oHSV bereft of immunostimulatory genes (T1 series) or expressing IL-12 alone (T2 series). In syngeneic mice the T3 series oHSV expressing murine IL-12 and PD-1 Ab was effective against a variety of murine tumors. Concurrent with enhanced cytolytic activity the T3 induced significant intratumoral accumulation of IL-12, PD-1 Ab and IFN-γ. Consistent with an earlier report of an inverse correlation between the volume of the tumor and the quantity of retained IFN-γ. The most effective oncolytic effect resulted from the administration of T3855 expressing both IL12 and anti PD-1 antibody or T2850 concurrently with intraperitoneal administration of anti PD-1 antibody alone. The least effective were single intraperitoneal administration of IL12 or PD-1 antibody. Intratumoral injection of T3 oHSV was most effective against murine tumors in comparison of either systemic administration of anti PD-1 ab and IL12 or intratumoral injection of T1 in combinations of systemic administration of anti PD-1 ab and IL12. Conclusions: We report the marriage in a single therapeutic agent of three distinct cancer therapies: the targeting of cancer cells by oncolytic viruses, the stimulation of immune system by IL12, and the production of immunotherapeutic antibodies against PD-1. The significant finding reported in this article is that the anti-tumor responses remain concentrated in the tumor environment.

Abstract
Increased concentrations of atmospheric greenhouse gases have led to a global mean surface temperature 1.0°C higher than during the pre-industrial period. We expand on the recent IPCC Special Report on global warming of 1.5°C and review the additional risks associated with higher levels of warming, each having major implications for multiple geographies, climates, and ecosystems. Limiting warming to 1.5°C rather than 2.0°C would be required to maintain substantial proportions of ecosystems and would have clear benefits for human health and economies. These conclusions are relevant for people everywhere, particularly in low- and middle-income countries, where the escalation of climate-related risks may prevent the achievement of the United Nations Sustainable Development Goals.
