Abstract
Granulosa cells are somatic cells located inside follicles that play a crucial role in the growth and development of follicles. Quercetin and tanshinone are two key monomers in traditional Chinese medicine that have antioxidant and anti-aging properties. The KGN cell apoptosis model caused by triptolide (TP) was employed in this work to investigate granulosa cell death and medication rescue. Quercetin and tanshinone therapy suppressed KGN cell death and oxidation while also regulating the expression of critical apoptosis and oxidation-related markers such as B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X protein (Bax). Further research revealed that the effects of Quercetin and Tanshinone were accomplished via deacetylation of FOXO3A in the cytoplasm and mitochondria via the SIRT1/SIRT3-FOXO3a axis. In summary, Quercetin and tanshinone protect KGN cells from apoptosis by reducing mitochondrial apoptosis and oxidation via the SIRT1/SIRT3-FOXO3a axis.

Abstract
We investigated the high energy spin excitations in electron-doped La_{2-x}Ce_{x}CuO_{4}, a cuprate superconductor, by resonant inelastic x-ray scattering (RIXS) measurements. Efforts were paid to disentangle the paramagnon signal from non-spin-flip spectral weight mixing in the RIXS spectrum at Q_{∥}=(0.6π,0) and (0.9π,0) along the (1 0) direction. Our results show that, for doping level x from 0.07 to 0.185, the variation of the paramagnon excitation energy is marginal. We discuss the implication of our results in connection with the evolution of the electron correlation strength in this system.

Abstract
AIM To review the imaging characteristics of granular cell tumours in the head and neck and assess their associations with pathological findings. MATERIALS AND METHODS Eleven patients (10 [91%] women, mean age 43 years) with histopathologically confirmed granular cell tumours were included in this study. Preoperative imaging studies were performed, including computed tomography (CT), magnetic resonance imaging (MRI), or ultrasound. The location of the tumours, their imaging features, and histopathological findings were analysed. RESULTS Among the 11 granular cell tumours, four (36%), three (27%), and two (18%) tumours were found in the submucosal layer, subcutaneous layer, and intramuscular area, respectively. On CT, all tumours exhibited homogeneous iso-attenuating enhancement compared with adjacent muscle, and nine out of the 11 tumours (81%) demonstrated well-defined margins. On T2-weighted imaging (T2WI), four out of five tumours (80%) demonstrated iso-signal intensity compared with adjacent muscles, and four tumours (80%) exhibited homogeneous signal intensity. The apparent diffusion coefficient (ADC) values ranged from 0.68-0.81 × 10-3 mm2/s. Histopathological examination revealed densely packed tumour cells with variable amounts of fibrous stroma. CONCLUSION Granular cell tumours were characterised by well-defined and iso-signals on T2WI and low mean ADC values, and were predominantly located in the submucosal, subcutaneous, or intramuscular areas in middle-aged women. The characteristic locations, demographic characteristics, and imaging findings can help to differentiate granular cell tumours from other soft-tissue tumours in the head and neck.

Abstract
Light intensity, wavelength, and photoperiod have a combined effect on chicken incubation. This study was conducted to evaluate the effect of 12-h light, 12-h dark (12L:12D) photoperiod of white light (380-780 nm, WL), blue light (455/447.5-462.5 nm, BL), and green light (525/515-535 nm, GL) in chicken perceived light intensity during layer incubation on hatching performance, embryo development, eye structure, and melatonin concentration. Three batches of eggs from Jinghong No. 1 layer breeder were used in this experiment. Light stimulation had no effect on hatchability, and no consistent effect on embryo weight and newly hatched chick weight. However, the average hatching time of white light group and green light group was 7.3 h and 5.5 h later than that of the control group. Therefore, the holding period of chicks was significantly shortened (P = 0.001) in these 2 light groups. Light stimulation had a significant effect on the thickness of retinal layers (P < 0.05), retinal layers of white light group was thicker than that of the other 3 groups. Melatonin levels of chicks hatched in the green light and blue light were significantly higher than that of chicks hatched in the white light and darkness (P < 0.05). It indicated that the monochrome green and blue light promoted the expression of melatonin in chicken embryos. No significant diurnal rhythms were found at the level of plasma melatonin in 4 groups on d 21 using cosine analysis. It was concluded that green light has a positive effect on embryo development and melatonin secretion, while white light probably has positive effect on eye development. Furthermore, both green and white light stimulation resulted in late hatch for layer egg incubation. The obtained results are important in determining the light protocol for chicken incubation.

Abstract
Currently, there is a limited amount of research on PEDOT:LS (poly(3,4-ethylenedioxythiophene):sulfonated lignin)-based hydrogels. While the addition of PEDOT:LS can enhance the conductivity of the gel, it unavoidably disrupts the gel network and negatively affects its mechanical properties. The preparation process and freezing resistance of the hydrogels also pose significant challenges for their practical applications. In this study, we have developed a novel self-catalytic system, PEDOT:LS-Fe3+, for the rapid fabrication of conductive hydrogels. These hydrogels are further transformed into eutectogels by immersing them in a deep eutectic solvent. Compared with conventional hydrogels, the eutectogels exhibit improved elongation, mechanical strength, and resistance to freezing. Specifically, the eutectogels containing 2 wt % PEDOT:LS as conductive fillers and catalysts demonstrate exceptional stretchability (∼460%), self-adhesion (∼14.6 kPa on paper), UV-blocking capability (∼99.9%), and ionic conductivity (∼1.2 mS cm-1) even at extremely low temperatures (-60 °C). Moreover, the eutectogels exhibit high stability and sensitivity in flexible sensing, successfully detecting various human motions. This study presents a novel approach for the rapid preparation of the hydrogels by utilizing lignin in the conductive PEDOT polymerization process and forming a self-catalytic system with metal ions. These advancements make the eutectogels a promising candidate material for flexible wearable electronics.

Abstract
In this work, an ethanol/water/glycerol ternary coagulation bath system was used to fabricate a hydrophobic PVDF membrane, which will have a considerable impact on the micromorphology. This change will further affect the performance of the membrane. After introducing glycerol into the coagulation bath, the precipitation process was finely regulated. The obtained results implied that glycerol could inhibit solid-liquid separation and promoted liquid-liquid separation. A pleasant discovery was that the mechanical properties of the membrane were improved because of the more fibrous polymers formed by liquid-liquid separation. Besides, a more uniform pore size can be achieved. A fascinating symmetrical interconnected fibrous and spherulitic structure was depicted by membranes fabricated with a coagulation bath consisting of 6% water, 34% ethanol, and 60% glycerol. This membrane had a high water contact angle of 146.6° and a small mean pore size of 0.46 μm. Enhanced tensile strength and elongation at break evidenced that the membrane enjoyed good robustness and flexibility. This facile approach provided the possibility to prepare membranes with tailored pore size and the required strength.

Abstract
The sample temperature in an externally heated diamond anvil cell (EHDAC) is generally measured by a thermocouple fixed to the pavilions of diamond anvils, ignoring the temperature difference between the thermocouple and the sample. However, the measured temperature depends strongly on the placement of the thermocouple, thus seriously reducing the accuracy of the temperature measurement and hindering the use of EHDAC in experiments requiring precise temperature measurements, such as high-pressure melting and phase-diagram investigations. In this study, the full width at half maximum (FWHM) of the 0-0 fluorescence line of strontium borate doped with bivalent samarium ions (SrBO4:Sm2+, SBO) is found to be highly sensitive to temperature and responds extremely rapidly to small temperature fluctuations, which makes it an excellent temperature indicator. We propose herein a precise method to measure temperature that involves measuring the FWHM of the 0-0 fluorescence line of SBO. This method is used to correct the temperature discrepancy between the thermocouple and the sample in an EHDAC. These corrections significantly improve the accuracy of temperature measurements in EHDACs. The accuracy of this method is verified by measuring the melting point of tin at ambient pressure. We also use this method to produce a tentative elementary phase diagram of tin up to 109 GPa and 495 K. This method facilitates high-pressure, high-temperature experiments demanding accurate temperature measurements in various disciplines. The study also discusses, in general, the experimental approach to measuring temperature.

Abstract
We report high-precision measurements of the deeply virtual Compton scattering (DVCS) cross section at high values of the Bjorken variable x_{B}. DVCS is sensitive to the generalized parton distributions of the nucleon, which provide a three-dimensional description of its internal constituents. Using the exact analytic expression of the DVCS cross section for all possible polarization states of the initial and final electron and nucleon, and final state photon, we present the first experimental extraction of all four helicity-conserving Compton form factors (CFFs) of the nucleon as a function of x_{B}, while systematically including helicity flip amplitudes. In particular, the high accuracy of the present data demonstrates sensitivity to some very poorly known CFFs.

Abstract
We present new precision measurements of the elastic electron-proton scattering cross section for momentum transfer (Q^{2}) up to 15.75 (GeV/c)^{2}. Combined with existing data, these provide an improved extraction of the proton magnetic form factor at high Q^{2} and double the range over which a longitudinal or transverse separation of the cross section can be performed. The difference between our results and polarization data agrees with that observed at lower Q^{2} and attributed to hard two-photon exchange (TPE) effects, extending to 8 (GeV/c)^{2} the range of Q^{2} for which a discrepancy is established at >95% confidence. We use the discrepancy to quantify the size of TPE contributions needed to explain the cross section at high Q^{2}.

Abstract
We report measurements of the exclusive neutral pion electroproduction cross section off protons at large values of x_{B} (0.36, 0.48, and 0.60) and Q^{2} (3.1 to 8.4 GeV^{2}) obtained from Jefferson Lab Hall A experiment E12-06-014. The corresponding structure functions dσ_{T}/dt+εdσ_{L}/dt, dσ_{TT}/dt, dσ_{LT}/dt, and dσ_{LT^{'}}/dt are extracted as a function of the proton momentum transfer t-t_{min}. The results suggest the amplitude for transversely polarized virtual photons continues to dominate the cross section throughout this kinematic range. The data are well described by calculations based on transversity generalized parton distributions coupled to a helicity flip distribution amplitude of the pion, thus providing a unique way to probe the structure of the nucleon.

Abstract
Except the good separation performance, the membranes used for oil-water mixture separation should be fabricated with as little wastewater produced as possible. Thus, we proposed a green tactic--water vapor induced phase inversion to prepare the high-strength and superhydrophilic/underwater superoleophobic nonwoven fabric-based cotton/PA6/PAN membranes which is based on the polymer/solvent/nonsolvent ternary system analysis. Differing from adding additives in polymer solution or coagulation bath, above proposed strategy has an "subtractive effect" with the advantages of constructing three-dimensional porous structure and greatly reducing the organic wastewater produced during preparation process. Moreover, the obtained cotton/PA6/PAN membranes exhibited unexpected performances for separating oil-in-water emulsions. An ultrahigh permeation flux of up to 478,000 L m-2 h-1 bar-1 with a separation efficiency of > 99.9% was obtained under the driving pressure of 1.6 KPa, which was one order of magnitude higher than the conventional separation membranes with similar properties. In addition, it is surprising that the cotton/PA6/PAN membranes can also extract water from the slick oil/water immiscible mixture. Therefore, it is expected that the cotton/PA6/PAN membranes can be used in practical oily wastewater purification.

Abstract
OBJECTIVE The aim of this study was to observe the protective effect of Ulinastatin on myocardial injury induced by doxorubicin (DOX) in rats. MATERIALS AND METHODS 30 male Sprague Dawley (SD) rats were divided into control group, DOX group, and Ulinastatin group by random number table method. The control group was intraperitoneally injected with saline, while the DOX group and the Ulinastatin group were injected intraperitoneally with DOX (2 mg/kg) once every other day to establish an acute myocardial injury (AMI) model. In the Ulinastatin group, Ulinastatin (1500 IU/100 mg) was injected intraperitoneally once a day for 2 weeks after the model was established. The changes in cardiac structure were observed with a light microscope, the changes in cardiac function in rats were detected with biochemical kits, and expression of oxidative stress and inflammatory response-related factors were detected by Western blotting, enzyme-linked immunosorbent assay (ELISA), and quantitative Real Time-Polymerase Chain Reaction (qRT-PCR). RESULTS Myocardial tissues in the control group were neatly arranged and dense, with complete and clear structure. The myocardial tissues in the DOX group were disorderly arranged, the interstitial fibrosis was evident, and the myocardial transverse striations broke and disappeared. The structure of tissues in Ulinastatin group was dramatically relieved compared with DOX group. The serum SOD and GSH-Px levels of the DOX groups were significantly lower than those of the control group, while the levels of MDA and ROS were dramatically higher than those of the control group. The serum SOD and GSH-Px level of Ulinastatin group were higher than that of DOX group, and the levels of MDA and ROS were lower than those of DOX group. LDH, AST, ALT, and CK levels were dramatically higher than those in the control group, while the above-mentioned serum myocardial zymogram levels in the Ulinastatin group were decreased. The expressions of IL-1β, IL-6, TNF-α, and iNOS in the DOX and Ulinastatin groups were dramatically higher than those in the control group, while the expressions of the above inflammatory factors in the Ulinastatin group were all inhibited. CONCLUSIONS Ulinastatin intervention can reduce myocardial injury in rats with DOX. The protective effect may be due to the elimination of oxygen free radicals, enhanced antioxidant enzyme activity, reduced lipid peroxidation and inflammatory responses, and thus repaired myocardial injury.

Abstract
The composite material composed of zinc sulfide, copper sulfide and porous carbon is prepared in this study, exhibiting excellent performances in the field of supercapacitor electrode and photocatalysts. In the degradation process of organic pollutants, zinc sulfide/copper sulfide with heterostructure effectively reduce the recombination rate of photo-generated electron-hole pairs. And the porous carbon substrate can not only accelerate the separation of photo-carriers but also provide numerous active sites. Furthermore, the sample can be easily separated after decomposing the organic pollutants. As a supercapacitor electrode, the combination of zinc sulfide/copper sulfide with large pseudo-capacitance and porous carbon material with excellent double-layercapacitance results in superior electrochemical performances. The composite electrode shows a high specific capacitance of 1925 mF cm-2/0.53 mAh cm-2 at 4 mA cm-2. And the symmetric flexible supercapacitor based on the composite electrode achieves an outstanding energy density (0.39 Wh cm-2 at the power density of 4.32 W cm-2). Therefore, the zinc sulfide/copper sulfide/porous carbonized cotton nanocomposites (pCZCS) prepared herein exhibit dual functions of photocatalysts with high efficiency as well as energy storage materials with high energy density, which is interesting and important for expanding the practical applications in cross fields.

Abstract
Objective: To analyze the epidemiological characteristics of a cluster of 5 confirmed COVID⁃19 cases related with the transmission in incubation period of initial case, and find out the infection source and transmission chain.. Methods: According to "The Prevention and Control Protocol for Coronavirus Disease 2019 (Third Edition)" issued by the National Health Commission, a field epidemiological survey was conducted for the 5 cases in January 2020. Nasopharyngeal swabs and sputum samples were collected from them for the detection of 2019-nCoV by real time RT-PCR. Multi prevention and control measures were taken, such as tracking and screening close contacts, medical isolation observation, investigating the epidemiological link, analyzing transmission chain. Results: Case 1, who had common environmental exposure with other COVID⁃19 cases, got sick on 20 January, 2020 and was confirmed on 1 February. Case 2 became symptomatic on 22 January and was confirmed on 27 January. Case 3 got sick on 25 January and was confirmed on 30 January. Case 4 had illness onset on 20 January and was confirmed on 1 February. Case 5 got sick on 23 January and was confirmed on 31 January. Among the 5 cases, case 2 died and the illness of other cases were effectively controlled. After exclusion of other common exposure factors, case 1 had a 6-hour meeting with case 2 and case 3 on 19 January. Case 2 and case 3 might be infected by case 1 during the incubation period. It is the key point for epidemiological investigation. Conclusion: The epidemiological investigation indicates that the transmission might occur in the incubation period of COVID-19 case, close attention should be paid to it in future COVID-19 prevention and control.

Abstract
OBJECTIVE Long non-coding RNAs (lncRNAs) have recently been identified as crucial regulators in colorectal cancer (CRC) progression. The aim of the study is to investigate the clinical role and biological effects of long non-coding RNA EWSAT1 in CRC. PATIENTS AND METHODS The expression of lncRNA EWSAT1 was detected in 106 cases of fresh CRC tissues and matched adjacent normal tissues by qRT-PCR analyses. The Kaplan-Meier analysis and log-rank test were used to assess the association between lncRNA EWSAT1 expression and overall survival (OS) rate of CRC patients. Cell proliferation and invasion capacity were evaluated by CCK8 assay, colony formation, and transwell invasion assays. The protein expression was detected using western blot analysis. RESULTS LncRNA EWSAT1 expression was abnormally higher in CRC tissues compared to matched adjacent normal tissues. Higher lncRNA EWSAT1 expression significantly associated with depth of invasion, lymph node metastasis, and advanced tumor-node-metastasis (TNM) stage in CRC patients. Patients with higher EWSAT1 expression exhibited shorter OS compared with patients with lower EWSAT1 expression. Furthermore, lncRNA EWSAT1 knockdown significantly suppressed cell proliferation and invasion in CRC. In addition, lncRNA EWSAT1 knockdown suppressed cell epithelial-mesenchymal transition (EMT) through reducing Snail1, Snail2, and N-cadherin expression, but increasing E-cadherin expression in CRC cells. CONCLUSIONS Downregulation of lncRNA EWSAT1 suppressed cell proliferation and invasion of CRC, which indicated that EWSAT1 may be a potential target of CRC treatment.

Abstract
OBJECTIVE The aim of this study was to investigate the effect of micro ribonucleic acid (miR)-497 on myocardial cell apoptosis in rats with myocardial ischemia/reperfusion (I/R) through the mitogen-activated protein kinase (MAPK)/extracellular regulated protein kinase (ERK) signaling pathway. MATERIALS AND METHODS A rat model of myocardial I/R was established, myocardial cells were extracted, and miR-497 was inhibited by inhibitors and overexpressed using miRNA mimics. The cell apoptosis rate was detected by flow cytometry and terminal deoxynucleotidyl transferase dUTP nick end labeling (TUNEL) assay. The interaction between miR-497 and ERK was determined by dual-luciferase reporter gene assay. The change in the protein level was measured via Western blotting (WB). RESULTS Up-regulation of miR-497 promoted myocardial cell apoptosis, and the 3'-untranslated region (3'-UTR) of ERK was highly conserved to combine with miR-497. The luciferase reporter gene assay showed that the transfection of miR-497 could significantly inhibit the relative luciferase activity in cells. CONCLUSIONS MiR-497 overexpression significantly down-regulated the ERK expression at messenger RNA (mRNA) and protein levels in cells. MiR-497 plays an important role in regulating I/R injury-induced myocardial cell apoptosis by targeting the ERK-induced apoptosis pathway.

Abstract
Previous studies have reported that miR-107 could be utilized as a potential peripheral biomarker in prostate cancer (PCa). However, the specific functions of miR-107 in prostate cancer and its relevant mechanisms are still unknown. The aim of this research was to investigate the cellular functions of miR-107 in PCa and reveal the relevant mechanisms. MicroRNA tailing quantitative real-time PCR (qRT-PCR) was adopted to measure the expression of miR-107 in PCa cell line DU145 and PC3, as well as in normal prostate cell line RWPE-1. The miR-107 expression pattern in PCa tissues and paired peritumoral tissues were determined by Chromogenic In Situ Hybridization (CISH). Cell viability, colony formation, flow cytometry cell cycle and apoptosis, wound healing and Transwell migration assays were performed to study the miR-107 functions in PCa cells. Further, qRT-PCR, western blot analysis and dual-luciferase reporter assays were conducted to verify the target of miR-107 in PCa. Results demonstrated that miR-107 was downregulated in PCa cells and tissues in comparison with normal prostate cells and peritumoral tissues, and the over-expression of miR-107 suppressed proliferation and induced G1/S arrest of PCa cells but had no effects on apoptosis or cell motility of PCa cells. MiR-107 was found to target cyclin E1 (CCNE1) in PCa cells by directly binding to its 3'-UTR. In conclusion, miR-107 could be a potential tumor suppressor in PCa, and the restoration of miR-107 might provide a new therapeutic option for PCa.

Abstract
OBJECTIVE We previously reported that genetic ablation of (Fibroblast Growth Factors Receptors) FGFR1 in knee cartilage attenuates the degeneration of articular cartilage in adult mice, which suggests that FGFR1 is a potential targeting molecule for osteoarthritis (OA). Here, we identified R1-P1, an inhibitory peptide for FGFR1 and investigated its effect on the pathogenesis of OA in mice induced by destabilization of medial meniscus (DMM). DESIGN Binding ability between R1-P1 and FGFR1 protein was evaluated by enzyme-linked immuno sorbent assay (ELISA) and molecular docking. Alterations in cartilage were evaluated histologically. The expression levels of molecules associated with articular cartilage homeostasis and FGFR1 signaling were analyzed by quantitative real-time polymerase chain reaction (qRT-PCR), Western blotting and immunohistochemistry (IHC). The chondrocyte apoptosis was detected by terminal-deoxynucleoitidyl transferase mediated nick end labeling (TUNEL) assay. RESULTS R1-P1 had highly binding affinities to human FGFR1 protein, and efficiently inhibited extracellular signal-regulated kinase (ERK)1/2 pathway in mouse primary chondrocytes. In addition, R1-P1 attenuated the IL-1β induced significant loss of proteoglycan in full-thickness cartilage tissue from human femur head. Moreover, this peptide can significantly restore the IL-1β mediated loss of proteoglycan and type II collagen (Col II) and attenuate the expression of matrix metalloproteinase-13 (MMP13) in mouse primary chondrocytes. Finally, intra-articular injection of R1-P1 remarkably attenuated the loss of proteoglycan and the destruction of articular cartilage and decreased the expressions of extracellular matrix (ECM) degrading enzymes and apoptosis in articular chondrocytes of mice underwent DMM surgery. CONCLUSIONS R1-P1, a novel inhibitory peptide for FGFR1, attenuates the degeneration of articular cartilage in adult mice, which is a potential leading molecule for the treatment of OA.

Abstract
BACKGROUND Although the hospitalization rate at early period of kidney transplantation (KT) is still high, the association between the hospitalization within 1 year after KT and graft survival is unclear. We investigated the incidence and causes of hospitalization and clinical outcome of the patients hospitalized within 1 year after KT. METHODS We retrospectively analyzed 174 KT recipients (KTRs) hospitalized within 1 year after KT between 2013 and 2015. RESULTS Among them, 84 (48%) KTRs were admitted within 1 year after KT, and the number of hospitalizations was 116. The mean time from KT to first hospitalization was 4.2 months. Seventy-eight percent of the patients were hospitalized for medical causes and 22% for surgical causes. The most common cause was cytomegalovirus infection (CMV) (23.3%), followed by acute rejection (11.2%) and urinary tract infection (10.3%). Recipients and donors in the hospitalized group were significantly older than the nonhospitalized group. The proportions of deceased donor KT, acute rejection, more than 50% panel-reactive antibody, and positive donor-specific antibody were significantly higher in the hospitalized group than in the nonhospitalized group. Graft and patient survivals were lower in the hospitalized group than in the nonhospitalized group. Deceased donor KT and acute rejection were independent risk factors for hospitalization. CONCLUSION The incidence of KTRs hospitalized within 1 year after KT was high. Most causes of hospitalization were CMV infection, acute rejection, and urinary tract infection. Therefore, the immunosuppression status of these patients should be closely monitored to reduce the hospitalization rate.

Abstract
OBJECTIVE To investigate the effect of decellularized osteochondral extracellular matrix (ECM) scaffold for osteochondral defect regeneration. DESIGN We compared the histological features and microstructure of degenerated cartilage to normal articular cartilage. We also generated and evaluated osteochondral ECM scaffolds through decellularization technology. Then scaffolds were implanted to osteochondral defect in rabbit model. After 12 weeks surgery, regeneration tissues were analyzed by histology, immunohistochemistry evaluation. And possible mechanisms of angiogenesis and cell migration were explored. RESULTS We demonstrated decreased cell numbers, formation of fibrous cartilage, lost microstructure and worse permeability in degenerated cartilage compared to normal cartilage. We also generated an osteochondral ECM scaffold with a hierarchical structure that exhibited low immunogenicity, high bioactivity, and well biocompatibility. We found that the ECM scaffold promoted tissue regeneration in osteochondral defects, which was dependent on the scaffold constituents and stratified three-dimensional microstructure as well as on its ability to inhibit angiogenesis and stimulate cell migration. CONCLUSIONS Our findings demonstrated that the biphasic hierarchical ECM scaffold represents a novel and effective biomaterial that can be used in the treatment of osteochondral defect.

Abstract
BACKGROUND The mean age of patients starting dialysis in Korea has increased to older than 60 years and the proportion of patients aged 65 and older exceeded 40% in 2014. Although the number of elderly dialysis patients is increasing rapidly, percentages of elderly patients undergoing kidney transplantation (KT) are very low. METHODS We retrospectively reviewed the medical records of patients who underwent KT at Keimyung University Dongsan Medical Center between 1982 and 2016. Elderly patients (≥65 years old) were compared with the control group of patients in their early sixties (60-64 years old). RESULTS Among a total of 1209 KT patients, those in their early sixties totaled 34 (2.8%) and the elderly totaled only 18 (1.5%). Patient and allograft survival rate showed no significant differences between the elderly and those in their early sixties. Death with a functioning graft accounted for 50% in both groups. However, occurrences of bacterial infection and tuberculosis were higher in the elderly (P = .011 and .047, respectively). In a multivariate analysis, longer duration of renal replacement therapy before KT and the occurrence of malignancy were independent risk factors for patient death (hazard ratio [HR], 1.027; P = .014; HR, 31.934; P = .016, respectively). Also, albuminuria at 6 months after KT was an independent risk factor for allograft loss (HR, 51.155; P = .016). CONCLUSION The overall survival rate of the elderly was not significantly lower than those in their early sixties. Even in the elderly, KT should not be delayed. In addition, careful surveillance for malignancy and measures to decrease the risk of infection are necessary.

Abstract
BACKGROUND Kidney re-transplantation is commonly considered to have a higher immunological risk than first kidney transplantation. Because of the organ shortage and increasing waiting lists, long-term outcomes of kidney re-transplantation are being studied. However, reports of re-transplantation outcomes are not common. We have reported our 30 years of experience with second kidney transplantations. METHODS Of 1210 kidney transplantations between November 1982 and August 2016 performed in our hospital, 105 were second kidney transplantations (2nd KT). Living donor KT was 44; deceased donor KT was 61. RESULTS Patient survival rates at 1, 5, and 10 years were 100%, 97.2%, and 90.7%, and graft survival rates were 97.0%, 94.6%, and 71.5%, respectively. The leading cause of graft failure in the 2nd KT was chronic rejection (60%). In addition, induction immunosuppressant, maintenance immunosuppressant, delayed graft function, and graft survival time at the 1st KT had a significant impact on graft survival time at the 2nd KT. CONCLUSIONS Reasonable results in both patient survival and graft survival rates were found in the 2nd KT. Careful monitoring of immunologic risk is needed.

Abstract
INTRODUCTION Although CA125 and the tumor immune response have been reported to be associated with pancreatic cancer, their prognostic value for advanced pancreatic cancer patients undergoing chemotherapy remain uncertain. We thus studied the prognostic value of the combination of the CA125 level with the CD4/CD8 ratio. METHODS After excluding patients who were lost to follow-up or for whom complete clinical data were missing, 369 participants were ultimately examined. Univariate and multivariate analyses were performed using the Cox hazards model, and Kaplan-Meier methods and log-rank tests were used for the comparison of survival rates. RESULTS Univariate and multivariate analyses showed that a high CA125 level and a high CD4/CD8 ratio were independent prognostic factors (CA125 ≥ 35 U/ml, Hazard Ratio (HR) = 1.90, p < 0.001; CD4/CD8 ≥ 1.8, HR = 1.37, p = 0.004). Moreover, after combining the CA125 level and CD4/CD8 ratio to form a new scoring system, the HR was substantially elevated (CA125 ≥ 35 U/ml and CD4/CD8 ≥ 1.8, score 2, HR = 2.76, 95% confidence interval: 2.04 to 3.74, p < 0.001). CONCLUSIONS A new scoring system based on the combination of the CA125 level with the CD4/CD8 ratio could further predict the prognosis of patients with advanced pancreatic cancer.

Abstract
Abstract
Triple negative breast cancer (TNBC) as a metastatic disease is currently incurable. Unfortunately reliable and reproducible methods for testing drugs against metastasis are not available. We have previously developed a robust metastatic model in which mice are pretreated with tumor cell-conditioned media (TCM) from human TNBC cells (MDA-MB-231 and SUM149) for 2 weeks prior to tumor cell inoculation. In this model we found reproducible metastases in lymph nodes (LN) and lungs within 4-5 weeks after orthotopic tumor inoculation [1]. We have discovered that the TNBC cells secrete large amounts of interleukin-6 (IL-6) that “educates” lymphatic endothelial cells (LEC) in the LN and lungs. Stat3, a transcription factor, gets activated and induces the synthesis of CCL5 and VEGF among other factors. CCL5 recruits the tumor cells to the LN and lungs; VEGF helps build blood vessels in the LN to facilitate tumor cell survival; VEGF produced in the lung helps the tumor cells extravasate into the lung. We have confirmed the importance of these factors by showing that inhibitors of these factors significantly inhibit metastasis.
In this report, using Maraviroc (CCR5 inhibitor) and cMR16-1 Ab (murine surrogate of the anti-IL-6R antibody), we investigated the effect of the combination treatment on the tumor growth and metastasis of orthotopic tumor xenografts generated from MDA-MB-231-Luc-D3H2LN cells. 2x106 TNBC cells tagged with luciferase were suspended in 100 μl PBS/Matrigel (1:1) and injected s.c. into female 3- to 4-week-old BALB/c nu/nu athymic mice pretreated with tumor cell-conditioned media (TCM) from TNBC cells for 2 weeks. We administered the Maraviroc (8 mg/kg Maraviroc, orally daily) and cMR16-1 Ab (i.p. 3-days per week) for 5 weeks. Our data show that tumor growth was dramatically inhibited by cMR16-1 Ab. Further, the drug combination of Maraviroc with cMR16-1 Ab caused significant reduction of TNBC tumor growth in mice compared to single agents. In addition, we measured thoracic metastases by adding luciferin to mice and measuring luminescence ex-vivo in the IVIS imager. Significantly, both single treatment of Maraviroc and the combination of Maraviroc with cMR16-1 abrogated the thoracic metastasis compared to control and single treatment of cMR16-1.
These findings implicate IL-6 and CCL5 signaling as a critical event in TNBC tumor growth and metastasis via crosstalk between cancer cells and stromal components. Further, these studies suggest that IL-6 and CCL5 act as key regulators orchestrating TNBC metastatic breast cancer. Therefore, we have provided evidence that supports the hypothesis that functional inhibition of the IL-6 and CCL-5 signaling pathway has the potential to circumvent TNBC growth and metastasis.

Abstract
BACKGROUND Vascular endothelial growth factor (VEGF) is highly expressed in many types of tumors, including pancreatic cancer. Tumor cellderived VEGF promotes angiogenesis and tumor progression. However, the role of VEGF in glucose metabolism remains unclear. OBJECTIVE We investigated the role and the underlying mechanism of VEGF in the glucose metabolism of pancreatic cancer cells. METHOD Pancreatic cancer cells were stimulated with VEGF165 for 1 or 2 h. The oxygen consumption rates (OCR) and extracellular acidification rates (ECAR) were measured using the Seahorse XF96 Extracellular Flux Analyzer. Glycolytic enzymes were detected by quantitative real-time PCR. Neuropilin 1 (NRP1) was silenced by shRNA in order to investigate its role in VEGF-induced glycolysis. Immunohistochemistry (IHC) was performed to identify the correlation among VEGF, NRP1 and hypoxia inducible factor 1α (HIF1α) in pancreatic cancer tissues. RESULTS VEGF stimulation led to a metabolic transition from mitochondrial oxidative phosphorylation to glycolysis in pancreatic cancer. HIF1α and NRP1 protein levels were both increased after VEGF stimulation. The down-regulation of NRP1 reduced glycolysis in pancreatic cancer cells. NRP1 and VEGF levels both correlated with HIF1α expression in pancreatic tumor tissues. CONCLUSION VEGF enhances glycolysis in pancreatic cancer via HIF1α up-regulation. NRP1 plays a key role in VEGF-induced glycolysis.

Abstract
Regulation of crucial lncRNAs involved in differentiation of chicken embryonic stem cells (ESCs) to spermatogonia stem cells (SSCs) was explored by sequencing the transcriptome of ESCs, primordial germ cells (PGCs) and SSCs with RNA-Seq; analytical bioinformatic methods were used to excavate candidate lncRNAs. We detected expression of candidate lncRNAs in ESCs, PGCs and SSCs and forecasted related target genes. Utilizing wego, david and string, function and protein-protein interactions of target genes were analyzed. Finally, based on string analysis, interaction diagrams and relevant signaling pathways were established. Our results indicate a total of 9657 lncRNAs in ESCs, PGCs and SSCs, with 3549 defined as significantly different. We screened 20 candidate lncRNAs, each demonstrating a greater than eight-fold difference in |logFC| value between groups (ESCs vs. PGCs, ESCs vs. SSCs and PGCs vs. SSCs) or specifically expressed in an individual cell type. qRT-PCR results indicated that expression tendencies of candidate lncRNAs were consistent with RNA-Seq. Fifteen cis and four trans target genes were forecasted. Based on wego and string analyses, we found lnc-SSC1, lnc-SSC5, lnc-SSC2 and lnc-ESC2 negatively regulated target genes SUFU, EPHA3, KLF3, ARL3 and TRIM8, whereas SHH, NOTCH, TGF-β, cAMP/cGMP and JAK/STAT signaling pathways were promoted, causing differentiation of ESCs into SSCs. Our findings represent a preliminary unveiling of lncRNA-associated regulatory mechanisms during differentiation of chicken ESCs into SSCs, filling a research void in male germ cell differentiation related to lncRNA. Our results also provide basic information for improving in vitro induction systems for differentiation of chicken ESCs into SSCs.

Abstract
In this opinion article we examine the relationship between penetrometer resistance and soil depth in the field. Assuming that root growth is inhibited at penetrometer resistances > 2.5 MPa, we conclude that in most circumstances the increases in penetrometer resistance with depth are sufficiently great to confine most deep roots to elongating in existing structural pores. We suggest that deep rooting is more likely related to the interaction between root architecture and soil structure than it is to the ability of a root to deform strong soil. Although the ability of roots to deform strong soil is an important trait, we propose it is more closely related to root exploration of surface layers than deep rooting.

Abstract
Recently a new class of metal alloys, of single-phase multicomponent composition at roughly equal atomic concentrations ("equiatomic"), have been shown to exhibit promising mechanical, magnetic, and corrosion resistance properties, in particular, at high temperatures. These features make them potential candidates for components of next-generation nuclear reactors and other high-radiation environments that will involve high temperatures combined with corrosive environments and extreme radiation exposure. In spite of a wide range of recent studies of many important properties of these alloys, their radiation tolerance at high doses remains unexplored. In this work, a combination of experimental and modeling efforts reveals a substantial reduction of damage accumulation under prolonged irradiation in single-phase NiFe and NiCoCr alloys compared to elemental Ni. This effect is explained by reduced dislocation mobility, which leads to slower growth of large dislocation structures. Moreover, there is no observable phase separation, ordering, or amorphization, pointing to a high phase stability of this class of alloys.

Abstract
Lipoic acid (LA) is a naturally existing substance which widely distributed in the cellular membranes and cytosol of animal cells. Its intracellular functions include quenching of free radicals and repairing oxidized proteins. The purpose of this study was to evaluate the effects of LA on post-weaning diarrhoea using a rat model. Sixty weaned rats were fed either a basal diet or a LA-supplemented diet, or a zinc oxide (ZnO)-supplemented diet as a positive control. Rats in the LA and ZnO groups had better performance and reduced incidence of diarrhoea (p < 0.05). Both LA and ZnO treatments enhanced intestinal homeostatic and architecture, significantly decreased urinary lactulose to mannitol ratios (p < 0.05) and increased the expression of the intestinal mucosal tight junction proteins occludin (OCLN) and zonula occludens protein-1 (ZO-1) (p < 0.05). LA significantly increased the activities of antioxidant enzymes, and reduced glutathione while decreasing the levels of oxidative glutathione and malondialdehyde in the intestinal mucosa (p < 0.05). Furthermore, an in vitro study indicated that supplementation with LA in IEC-6 intestinal epithelial cells significantly enhanced the expression of OCLN and ZO-1 under hydrogen peroxide-induced oxidative stress. Collectively, these results suggest that LA relieves post-weaning diarrhoea by reducing intestinal permeability and improving antioxidant indices.
