Suiçmez Eylem,Tural Egemen,Dayan Akın 대한수면학회 2024 sleep medicine research Vol.15 No.1

Background and Objective The study aimed to investigate the sleep quality of type 2 diabetic patients with and without foot ulcers, to determine whether there was a difference in sleep quality between them, and to examine the effect of diabetic foot ulcers on sleep quality.Methods Our prospective cross-sectional study was conducted between April and September 2021 at the Family Medicine Diabetes Clinic and Diabetic Foot Clinic of the hospital. A total of 146 patients were included in the study, of whom 64 had foot ulcers and 82 did not, and met the inclusion criteria. The patients were administered a patient information questionnaire that included sociodemographic data, waist circumference, HbA1c, diabetes duration, diabetes complication information, as well as the Pittsburgh Sleep Quality Index.Results The mean age of the individuals participating in the study was 61.94 ± 10.34 years. According to the Pittsburgh Sleep Quality Index classification, 25.0% (n = 16) of individuals with diabetic foot ulcers had good sleep quality while 42.7% (n = 35) of individuals without diabetic foot ulcers had good sleep quality. A statistically significant relationship was found between diabetic foot ulcers and Pittsburgh Sleep Quality Index classification (p = 0.026). According to the multivariate logistic regression model, diabetic foot ulcers increased the risk of poor sleep quality by 2.64 times.Conclusions Our study showed that the presence of diabetic foot ulcers adversely affects sleep quality. Good sleep quality contributes to quality of life, wound healing, and diabetes control. Therefore, improving sleep quality in diabetic foot patients is important.

Irreversibly Adsorbed Tri-metallic PtBiPd/C Electrocatalyst for the Efficient Formic Acid Oxidation Reaction

Sui, Lijun,An, Wei,Rhee, Choong Kyun,Hur, Seung Hyun The Korean Electrochemical Society 2020 Journal of electrochemical science and technology Vol.11 No.1

The PtBi/C and PtBiPd/C electrocatalysts were synthesized via the irreversible adsorption of Pd and Bi ions precursors on commercial Pt/C catalysts. XRD and XPS revealed the formation of an alloy structure among Pt, Bi, and Pd atoms. The current of direct formic acid oxidation (I_d) increased ~ 8 and 16 times for the PtBi/C and PtBiPd/C catalysts, respectively, than that of commercial Pt/C because of the electronic, geometric, and third body effects. In addition, the increased ratio between the current of direct formic acid oxidation (I_d) and the current of indirect formic acid oxidation (I_ind) for the PtBi/C and PtBiPd/C catalysts suggest that the dehydrogenation pathway is dominant with less CO formation on these catalysts.

Mean value first principle engine model for predicting dynamic behaviour of two-stroke marine diesel engine in various ship propulsion operations

Sui Congbiao,de Vos Peter,Stapersma Douwe,Visser Klaas,Hopman Hans,Ding Yu 대한조선학회 2022 International Journal of Naval Architecture and Oc Vol.14 No.1

Analysis of ship propulsion system performance is often performed using detailed hydrodynamic models to assess load changes, which are subsequently compared to static engine limits, or by detailed engine models that are rarely integrated with sufficiently detailed propulsion models for load change estimation. To investigate the dynamic engine (overloading) behaviour and ship propulsion performance under various heavy operating conditions, a Mean Value First Principle Parametric (MVFPP) engine model is integrated into a ship propulsion system model in this paper. An upgraded thermodynamic-based MVFPP model for two-stroke marine diesel engines is presented, in particular a newly developed MVFPP gas exchange model. Based on the integrated propulsion system model of a benchmark ocean-going chemical tanker, the engine dynamic behaviour during ship acceleration, deceleration and crash stop has been investigated. Results show that, during dynamic processes, the engine could be thermally overloaded even if the engine power trajectory is inside the static engine operating envelope. The paper contributes to finding proper indicators for thermal overloading of modern two-stroke marine diesel engines. It is demonstrated that when matching the engine with the propeller and designing the ship propulsion control system, not only the static engine operating envelope, but also the dynamic engine behaviour should be considered.

An Improved Modulation Scheme for Voltage Balancing in Modular Multilevel Converter

Sui, Shunke,Yang, Rongfeng,Xu, Dianguo The Korean Institute of Electrical Engineers 2014 The Journal of International Council on Electrical Vol.4 No.2

With the continuous development of power electronic technology toward the high voltage and high-power conversion, the Modular Multilevel Converter (MMC) has attracted research attention. Since a large number of capacitors, voltage balancing problem becomes one of the key technologies of the MMC. To resolve the voltage balancing problem, this paper presents a novel voltage balancing modulation scheme, which control the instantaneous power of each sub-module timely by adjusting carriers offset in PWM, and the respective capacitor voltage could be stabilized at a set value. Simulation results based on MATLAB / SIMULINK environment are provided to testify to the effectiveness of the proposed method.

Temperature-Dependent Structural and Transport Properties of Liquid Transition Metals

Sui Yang,Xuping Su,Jianhua Wang,Nai-Yong Tang 대한금속·재료학회 2010 METALS AND MATERIALS International Vol.16 No.6

The evolution of the atomic structures and diffusivity of liquid transition metals with increasing temperature has been studied here using molecular dynamics. An analysis of Honeycutt and Andersen (HA) Indices indicates that relatively low order atomic clusters of rhombohedra-related structures increase with an increase in temperature. The results illustrate that the distortion in the local structural order with a predominant rhombohedra character enhances the diffusivity in liquid metals. The excess entropy approximated by the two-body contribution increases with the distortion of the local structural order traced by the HA Indices. The relationship between the excess entropy and the reduced diffusion coefficient supports the universal scaling law proposed by M. Dzugutov. The calculated diffusivities were compared with predictions of four diffusion models. The temperature dependence of the diffusivity cannot be described by the Arrhenius Law, the moving oscillator model or the free volume model but rather by the density fluctuation model with the square proportionality of temperature.

Emodin Inhibits Breast Cancer Cell Proliferation through the ERα-MAPK/Akt-Cyclin D1/Bcl-2 Signaling Pathway

Sui, Jia-Qi,Xie, Kun-Peng,Zou, Wei,Xie, Ming-Jie Asian Pacific Journal of Cancer Prevention 2014 Asian Pacific journal of cancer prevention Vol.15 No.15

Background: The aim of the present study was to investigate the involvement of emodin on the growth of human breast cancer MCF-7 and MDA-MB-231 cells and the estrogen (E2) signal pathway in vitro. Materials and Methods: MTT assays were used to detect the effects of emodin on E2 induced proliferation of MCF-7 and MDA-MB-231 cells. Flow cytometry (FCM) was applied to determine the effect of emodin on E2-induced apoptosis of MCF-7 cells. Western blotting allowed detection of the effects of emodin on the expression of estrogen receptor ${\alpha}$, cyclin D1 and B-cell lymphoma-2 (Bcl-2), mitogen-activated protein kinases (MAPK) and phosphatidylinostiol 3-kinases (PI3K). Luciferase assays were emplyed to assess transcriptional activity of $ER{\alpha}$. Results: Emodin could inhibit E2-induced MCF-7 cell proliferation and anti-apoptosis effects, and arrest the cell cycle in G0/G1 phase, further blocking the effect of E2 on expression and transcriptional activity of $ER{\alpha}$. Moreover, Emodin influenced the ER ${\alpha}$ genomic pathway via downregulation of cyclin D1 and Bcl-2 protein expression, and influenced the non-genomic pathway via decreased PI3K/Akt protein expression. Conclusions: These findings indicate that emodin exerts inhibitory effects on MCF-7 cell proliferation via inhibiting both non-genomic and genomic pathways.

Sui, Shuang,Jiao, Zhen,Niyazi, Mayinuer,Sulaiya, Sulaiya,Lu, Ping,Qiao, You-Lin Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.10

We investigated the distribution of HPV genotypes in Uyghur women in Xinjiang region of China, and behavioral factors which could predispose them to HPV infection. In this cross-sectional study, women aged 15-59 years were recruited by cluster sampling method in Yutian region in 2009. Liquid-based cytology samples were analyzed centrally for HPV genotype with a linear array detector. Univariate and multivariate logistic regression analyses were performed to identify behavioral risk factors for HPV infection. A total of 883 Uyghur women were recruited successfully. The prevalence of high-risk HPV and low-risk HPV were 7.25% and 1.58%, respectively; the most common HPVs were HPV16, 51, 31, 39 and 58. We found that age of first sexual intercourse was a strong predictor for HPV infection (odds ratio of 4.01 for ${\leq}15$ years versus ${\geq}25$). Having sexual partners ${\geq}3$ was the second predictor (OR 3.69, 95% CI 2.24-7.16). Cleaning the vagina after sex showed an increased risk of HPV infection (OR 2.72; 95% CI 1.98-5.13); Using the condom showed protective factors for HPV infection (OR 0.36; 95%CI0.12-0.53). HPV16, 51, 31, 39 and 58 were the priority types; the age of first sexual intercourse was identified as a major risk factor for HPV infection. Other notable risks were number of sexual partners and cleaning the vagina after sex. Changing these behavioral risk factors could help to reduce the occurrence of cervical cancer in this population.
