Abstract
Background:Radiotherapy and chemoradiation are well-established therapies for patients with squamous cell carcinoma of the head and neck (SCCHN). In aging societies, also the incidence of SCCHN in elderly patients is rising. Because of the underrepresentation of elderly patients in scientific trials, we evaluated the feasibility of adjuvant radiotherapy and chemoradiation in patients with SCCHN aged >70 years. Methods:All patients had been >70 years at the time of diagnosis and received adjuvant radiotherapy or, if feasible, chemoradiation at the University Medical Centre Regensburg between 2004 and 2018.71 patients -most with SCCHN UICC stage IVa- with a median age of 75 years were included; 9 patients received concomitant chemoradiation. Median follow-up was 27 months (IQR 18 – 62 months).Results:Radiotherapy and chemoradiation was well tolerated. 62 patients (87.3%) underwent treatment without interruption, and 65 patients (91.5%) completed radiotherapy with 95% of the initially prescribed dose. Median dose for all patients was 64 Gy (IQR: 60 – 66 Gy). 6/9 patients received at least 75 % of the planned chemotherapy dose. 37 patients (52.1%) developed acute toxicity CTC grade III or IV.Overall survival was 87 % after 12 months, 67 % after 24 months and 41 % after 60 months. Median overall survival was 51 months (IQR: 19 - 99 months). Local tumour control was 99 % after 12 months, 88 % after 24 months and 76 % after 5 years.Conclusion:Feasibility of adjuvant radiotherapy and chemoradiation in our collective of elderly patients with SCCHN was good. Particularly local tumour control was satisfactory. Overall survival does not seem to differ between elderly and younger patients or patients unselected for age. De-intensification of treatment because of age does not seem justified.

Abstract
Background: The relationship between cancer and coagulation have been intensively studied in recent years, however, the effects of coagulation factors on oral squamous cell carcinoma (OSCC) had not been reported. This study aimed to investigate the relationship between preoperative D-dimer (DD), fibrinogen (FIB), platelet (PLT) and OSCC, as well as the prognostic value of them. Methods: We retrospectively investigate a total of 202 OSCC patients treated in Guanghua Hospital of Stomatology, Sun Yat-sen University. Baseline demographic and clinicopathological information as well as both preoperative and postoperative DD, FIB and PLT results were collected from each patient if available, all patients were follow-up to disease progression, death or end of study. The correlations between preoperative DD, FIB, PLT and other clinical features, therapeutic effect and PFS were analyzed statistically, postoperative DD and surgical parameters were also analyzed.Results: Preoperative DD were found significantly correlated with T stage, N stage, Clinical stage and relapse of OSCC (P=0.000, 0.001, 0.000 and 0.000, respectively). Univariate and multivariate Cox regression analysis showed that, high preoperative DD independently predict poor prognosis in patients with OSCC (r=2.1, P=0.033). While FIB and PLT showed no prognostic values. Postoperative DD were found significantly correlated with preoperative DD and surgical type, but not the time consuming of surgery (P=0.005, 0.001 and 0.244, respectively). Conclusion: In this study, for the first time, we reported that, preoperative plasma DD was an independent predictor for OSCC stage and patient survival.

Abstract
Background

The majority of patients with type 4 gastric cancer have distant metastases with extremely poor prognosis. Consequently, considering a therapeutic strategy that improves the prognosis of these patients is clinically important. The present study aimed to assess the clinical indication and prognostic impact of surgery in patients with type 4 gastric cancer who underwent chemotherapy.
Methods

A total of 67 patients with type 4 gastric cancer who underwent chemotherapy were retrospectively enrolled. All patients were grouped into progressive disease (PD) and non-PD groups by tumor response to chemotherapy.
Results

Distant metastases occurred in 58 patients. With regard to tumor response, 16 and 51 patients had PD and non-PD, respectively. The prognosis was significantly poorer in patients with PD than in those with non-PD (p < 0.0001). Among 23 patients who underwent surgery after chemotherapy, 21 had a R0 resection. The presence or absence of surgery was significantly correlated with age, first-line chemotherapeutic regimen, lymph node metastasis, clinical stage, number of distant metastatic sites, peritoneal dissemination, and tumor response (p = 0.0412, p = 0.0096, p = 0.0024, p = 0.0059, p = 0.0128, and p = 0.0020, and p = 0.0066, respectively). Multivariate analysis selected tumor response and surgery as an independent prognostic factor (p = 0.0001 and p = 0.0009, respectively). Moreover, multivariate analysis for the surgery group demonstrated that metastatic nodal status (N0-1 vs N2-3) and residual tumor status (R0 vs R1-2) were significant independent prognostic factors (p = 0.0258 and p = 0.0458, respectively).
Conclusion

Our retrospective study suggests that surgery after chemotherapy for type 4 gastric cancer may improve the prognosis of responders with N0-1 status and a curative R0 resection.

Published: July 2020

Abstract
BACKGROUND Protein synthesis is regulated by the availability of amino acids, the engagement of growth factor signaling pathways and ATP levels sufficient to support translation. Crosstalk between these inputs is extensive, yet other regulatory mechanisms remain to be characterized. For example, the translation initiation inhibitor Rocaglamide A (RocA) induces Thioredoxin Interacting Protein (TXNIP). TXNIP is a negative regulator of glucose uptake, thus its induction by RocA links translation to the availability of glucose. MondoA is the principal regulator of glucose-induced transcription and its activity is triggered by the glycolytic intermediate, glucose 6-phosphate (G6P). MondoA responds to G6P generated by cytoplasmic glucose and mitochondrial ATP (mtATP), suggesting a critical role in the cellular response to these energy sources. TXNIP expression is entirely dependent on MondoA, therefore, we investigated how protein synthesis inhibitors impact its transcriptional activity. METHODS We investigated how translation regulates MondoA activity using cell line models and loss-of-function approaches. We examined how protein synthesis inhibitors effect gene expression and metabolism using RNA-sequencing and metabolomics, respectively. The biological impact of RocA was evaluated using cell lines and Patient-Derived xenograft Organoid (PDxO) models. RESULTS We discovered that multiple protein synthesis inhibitors, including RocA, increase TXNIP expression in a manner that depends on MondoA, a functional electron transport chain and mtATP synthesis. Furthermore, RocA increases mtATP and G6P levels and TXNIP induction depends on interactions between the Voltage-Dependent Anion Channel (VDAC) and hexokinase, which generates G6P. RocA treatment impacts the regulation of ~1200 genes and ~250 of those genes are MondoA-dependent. RocA treatment is cytotoxic to Triple Negative Breast Cancer cell lines and shows preferential cytotoxicity against ER- PDxO breast cancer models. Finally, RocA-driven cytotoxicity is partially-dependent on MondoA or TXNIP. CONCLUSIONS Our data suggest that protein synthesis inhibitors rewire metabolism, resulting in an increase in mtATP and G6P, the latter driving MondoA-dependent transcriptional activity. Further, MondoA is a critical component of the cellular transcriptional response to RocA. Our functional assays suggest that RocA or similar translation inhibitors may show efficacy against ER- breast tumors and that the levels of MondoA and TXNIP should be considered when exploring these potential treatment options.

Abstract
Background: World Health Organization has declared Coronavirus disease (COVID-19) as a Public Health Emergency of International Concern. It has killed thousands and millions are infected worldwide. Though COVID-19 is supposed to be primarily a disease of respiratory system, it also has widespread implications on other systems as well. The aim of this systematic review is to summarize the cardiovascular implications of COVID-19. Methods: PubMed, PubMed Central, EMBASE, and Google Scholar were searched for peer-reviewed articles which aimed to delineate the cardiovascular implications of COVID-19.Results: A total of six articles (five original articles and one case report) were included. We found diverse cardiovascular implications of COVID-19 ranging from acute cardiac injury to death. New onset abnormalities in electrocardiogram or echocardiogragram, elevated plasma levels of cardiac troponin, NT-proBNP, and D-dimer have role in early identification of acute cardiac injury in such patients. Additionally, cardiac troponin and NT-proBNP can be used to evaluate prognosis and possible need for intensive care in these patients.Conclusion: Acute cardiac injury is common in patients with COVID-19. Aggressive supportive management based on prognostic indicators along with management of heart failure, arrhythmias, acute coronary syndrome and thrombosis can improve clinical outcomes in such patients.

Abstract
Background: Accumulating evidence has indicated the remarkable roles of long non-coding RNAs (lncRNAs) as oncogenes or tumor suppressors in many malignancies. The involvement of lncRNA GATA6-AS1 in cancers remains largely undiscovered. Herein, our research was aimed at elucidating the function and mechanism of GATA6-AS1 in lung adenocarcinoma (LUAD).Methods: Gene expression was measured through qRT-PCR and WB. Cell proliferation ratio was determined using CCK-8 and EdU assays. Cell apoptosis ratio was determined using TUNEL and flow cytometry assays. Molecular interactions were examined through RIP, RNA pull-down and luciferase reporter assays.Results: GATA6-AS1 expression was markedly down-regulated in LUAD cell lines. GATA6-AS1 could inhibit LUAD cell proliferation and promote cell apoptosis. Mechanistically, GATA6-AS1 was identified as the molecular sponge for miR-331-3p, whose knockdown in LUAD cells could reinforce the tumor-suppressing effects of GATA6-AS1 overexpression. Moreover, GATA6-AS1 functions as a competing endogenous RNA (ceRNA) through sequestering miR-331-3p to deregulate SOCS1, thus inhibiting JAK2/STAT3 signaling pathway and suppressing LUAD cell viability.Conclusions: These results demonstrate the tumor-suppressing function and mechanism of lncRNA GATA6-AS1 in LUAD cells. The axis of GATA6-AS1/miR-331-3p/SOCS1/JAK2/STAT3 can be adopted as a novel approach for LUAD treatment.

Authors: Xu Lei , Jin Yu , Qin Xing 
Published: July 2020

Abstract
Background: Head and neck squamous cell carcinoma (HNSCC) is one of the most prevalent malignancy worldwide with high incidence and mortality. Recently, it has been well established that tumor microenvironment (TME) is intimately associated with cancer progression, in which the infiltration of immune and stromal cells could be exploited as effective biomarkers for cancer diagnosis and prognosis. In this study, we aimed to investigate HNSCC microenvironment to identify significant genes involved in carcinogenesis.
Methods: The ESTIMATE algorithm was applied to calculate immune scores and stromal scores based on the gene expression profiles downloaded from The Cancer Genome Atlas (TCGA) database and the correlation of these scores with clinical parameters and prognosis was further analyzed. Differential expression analysis and functional enrichment analysis were performed by R software.
Results: Immune scores and stromal scores were calculated by ESTIMATE algorithm and their correlations with clinicopathological characteristics of HNSCC patients were identified. Differentially expressed genes (DEGs) based on two scores were identified and subjected to functional analysis, demonstrating their close associations with tumor immunity. Hub genes were selected from which CCR2, CCR4, CCR8 and P2RY14 were found to be significantly associated with the survival rate of HNSCC patients.
Conclusions: In summary, we made a comprehensive analysis of HNSCC microenvironment and illustrated several key immune-related genes, which may provide evidences for the development of precision immunotherapy.

Published: July 2020

Abstract
Background Hypoglycemic incidents in older people can cause severe health problems, enhance general age-related disabilities and cause frailty. Little is known about incidence of hypoglycemia in older home-dwelling people with diabetes. Thus, the aim of this study was to investigate the feasibility of using continuous glucose monitoring (CGM) and standardized questionnaires on issues associated with increased risk of hypoglycemia among older home dwelling individuals with diabetes type 2 receiving home care. Methods CGM with the Ipro2 blinded monitoring system were performed for five days in six home-dwelling individuals ≥ 75 years diagnosed with diabetes and receiving home care. Demographic (age, gender, living arrangements) and clinical data (diabetes diagnoses and duration, diabetes medication, documented treatment goal, available glycosylated hemoglobin (HbA1c),) were collected from electronic patient records in home care services. Feasibility (ease of use, quality of data, time spent) of standardized questionnaires to identify the risk of hypoglycemia (the McKellar Risk Assessment Tool), risk of malnutrition (the Mini Nutritional Assessment (MNA)), functional status (the Individual-based Statistics for Nursing and Care Services (IPLOS)) and cognitive status (the Mini Mental Status Exam (MMSE)) was also assessed. Questionnaire data were collected by a study nurse in the individuals’ home.Results The practical use of CGM was satisfactory, with no major remarks about discomfort or technical errors, except for one participant with skin reaction (redness). Collecting data with the McKellar Risk Assessment Tool, MNA and IPLOS worked well according to quality of data, time spent and ease of use. The MMSE survey required extensive training of personnel to be conducted. Conclusion The feasibility study inform an upcoming study on the incidence and risk factors of hypoglycemia in home dwelling older individuals, were we will reconsider the use of the MMSE questionnaire. The use of blinded CGM in this population was well tolerated and can be used ‘as is’ for future studies.
In Silico Assessment of 5-FU Therapy via A Mathematical Model with Fuzzy Uncertain Parameters
Authors: Shafiekhani Sajad , Jafari Amir. H. , Jafarzadeh L. , Gheibi N. 
Published: July 2020

Abstract
Background: Ordinary differential equation (ODE) models widely have been used in mathematical oncology to capture dynamics of tumor and immune cells and evaluate the efficacy of treatments. However, for dynamic models of tumor-immune system (TIS), some parameters are uncertain due to inaccurate, missing or incomplete data, which has hindered the application of ODEs that require accurate parameters. Methods: We extended an available ODE model of TIS interactions via fuzzy logic to illustrate the fuzzification procedure of an ODE model. Fuzzy ODE (FODE) models, in comparison with the stochastic differential equation (SDE) models, assigns a fuzzy number instead of a random number (from a specific probability density function) to the parameters, to capture parametric uncertainty. We used FODE model to predict tumor and immune cells dynamics and assess the efficacy of 5-FU. The present model is configurable for 5-FU chemotherapy injection timing and propose testable hypothesis in vitro/ in vivo experiments. Result: FODE model was used to explore the uncertainty of cells dynamics resulting from parametric uncertainty in presence and absence of 5-FU therapy. In silico experiments revealed that the frequent 5-FU injection created a beneficial tumor microenvironment that exerted detrimental effects on tumor cells by enhancing the infiltration of CD8+ T cells, and NK cells, and decreasing that of myeloid-derived suppressor (MDSC) cells. We investigate the effect of perturbation on model parameters on dynamics of cells through global sensitivity analysis (GSA) and compute correlation between model parameters and cell dynamics. Conclusion: ODE models with fuzzy uncertain kinetic parameters cope with insufficient experimental data in the field of mathematical oncology and can predict cells dynamics uncertainty band. In silico assessment of treatments considering parameter uncertainty and investigating the effect of the drugs on movement of cells dynamics uncertainty band may be more appropriate than in crisp setting.

Published: July 2020

Abstract
SDG711 is a histone H3K27me2/3 transmethylases in rice, homolog ofCLFin Arabidopsis, that plays key roles in regulating of flowering time and panicle development. In this work, we investigated that the role of SDG711 in rice seed development. Overexpression and down-regulation of SDG711lead to the decrease and increase of the expression level of genes related to starch accumulation, resulting in smaller seed or even seed abortion. ChIP assay showed that SDG711-mediated H3K27me3 changed significantly in genes related to endosperm development and SDG711 can directly bind to the gene body region of several starch synthesis genes and amylase genes. In addition, H3K4me3 and H3K9ac modifications also cooperate with H3K27me3 to regulate the development of endosperm. Our results suggested that the crosstalk of SDG711-mediated H3K27me3 with H3K4me3 and H3K9ac are involved in starch accumulation to control normal seed development.
A Rotor Coupling Fault Mechanism Modeling Based on the Deformation-Motion Vector Analysis Method
Authors: jun hu 
Published: July 2020

Abstract
In view of the limitation of the numerical method for coupling faults of rotating machinery, a modeling method for coupling faults of rotor, Deformation-Motion Vector Analysis Method, is purposed in order to explain the fault mechanism more thoroughly and universally. Firstly, the “Deformation-Motion” is defined by fault and the relationship between fault deformation and periodic signal is established by Fourier series. Secondly, the “Vector Analysis” analyzes the deformation-motion in the dynamic coordinate system, and establishes the relationship between the fault deformation-motion and the periodic excitation force by using the dynamic and static coordinate systems. Thirdly, the analytical solution is obtained by harmonic balance method, and the coriolis acceleration term is first found in the analytical solution of rotating machinery failure. Finally, the validity of the modeling method and the correctness of the analytical solution are verified by engineering practice.

Published: July 2020

Abstract
Background: Radiotherapy plays an important role in the treatment of hepatocellular carcinoma (HCC). Cyclin G1 was a novel member of the cyclin family, and it is abnormally expressed in HCC. The aim of this study was to investigate the role of cyclin G1 in the radiotherapy of HCC cells. Methods: The expression of cyclin G1 was silenced by transfection of cyclin G1-siRNA into HepG2 cells, and the expression of cyclin G1 mRNA and protein was measured by qRT-PCR and western blot analysis. The proliferation was analysed by MTT assay, and the radiosensitivity of HCC cells was detected by using a colony formation assay and a xenograft tumour model. The expression of apoptosis-related proteins (Bcl-2 and Bax) was detected by western blot analysis. Results: The expression of cyclin G1 mRNA and protein in HepG2-cyclin G1-siRNA cells is significantly decreased compared with that in HepG2 cells. Silencing the expression of cyclin G1 inhibits the proliferation of HCC cells and enhances the radiosensitivity of HepG2 cells in vitro and in vivo. HepG2-cyclin G1-siRNA significantly decreases Bcl-2 expression and increases Bax expression in cells.Conclusion: Silencing the expression of cyclin G1 enhances the radiosensitivity of HCC cells in vitro and in vivo, and the mechanism is probably related to the regulation of apoptosis-related proteins.
