Zou, Jun Techno-Press 2022 Ocean systems engineering Vol.12 No.2

In oil and gas industry, FPSO concept is the most popular hull form and ship shaped hull form dominants the FPSO market. Only a non-ship-shaped hull in operations with minor market shares is the cylindrical FPSO hull with medium to small storage capability. To add contracting options and competitions to reduce field development costs, an innovative turretless low motion hull, eco-FPSO, with 1MM bbls oil storage capacity and suitable for installing topsides modulars and equipping with regular SCRs, was first introduced in Zou (2020a). Dynamic characteristic responses of the eco-FPSO compared to the traditional SS-FPSO hull and DD-Semi platform are presented and discussed in this paper, suitability and feasibility of the proposed hull have been demonstrated and validated through extensive analyses in 10-yrp, 100-yrp and 1,000-yrp hurricanes in ultra-deepwater central GoM.

Bingshuang Zou,김태우,최순철 대한치과교정학회 2005 대한치과교정학회지 Vol.35 No.5

본 연구는 안면비대칭이 있는 환자의 측두하악관절원반 형태와 위치를 평가하고 악관절내장증과 안명비대칭 간의 관계를 규명하기 위하여 시행되었다. 남자 10명 및 여자 27명으로 구성된 안명비대칭 환자 37명의 74개의 TMJ MRI를 사용하였으며, 대상 집단의 연령은 12세에서 44세까지의 범위로 평균 21.4세였다. 시상 및 두정 TMJ MRI를 최대감합위 및 최대개구위에서 채득한 후 부분전방변위, 전방변위, 회전 또는 측방 원반변위 등 원반변위의 종류를 기록하였으며, 원반의 모양, 위치, 그리고 원반의 변위 및 회전을 MRI tracing 상에서 판독하였다. 악관절내장증의 증상은 정상, 정복성 전방원반변위 (ADDR). 그리고 비정복성 전방원반변위(ADDNR)집단으로 분류하였으며, 환자는 양측성 정상. 편측 혹은 양측 내장증 집단으로 분류하였다. 약 70%의 환자에서 편측성 또는 양측성 내장증을 보였으며, 통계분석 결과 ADD. 특히 회전성 ADD가 변위측에서 더 높은 빈도로 나타났으나 반대측에서는 원반의 위치가 정상인 경우가 많았다 (p<0.01).변위측의 원반은 모양의 변형 및 하전방 변위를 유의하게 더 나타냈다. 그러나 반대쪽은 개구시 원반이 수직방향으로 과운동성이 관찰되었다. 이 연구는 안면비대칭 환자에서 ADD의 종류가 원반의 모양,경사,변위 각도,변위의 수직거리 및 회전각도와 연관이 있다는 것을 제시한다. The present study was conducted to examine the morphometrics and function of the disk on both sides among patients with facial asymmetry (FA) and to elucidate plausible correlations between internal derangement (ID) and FA. The sample was composed of 10 males and 27 females with FA. The disk status of all subjects was evaluated by biateral high resolution magnetic resonance scans in the sagittal (closed and open) and coronal (closed) planes. Five types of disk displacement were identified accordingly. The disk function was diagnosed as normal disk function, disk displacement with reduction, and disk displacement without reduction. The disk shape on sagittal MRI in closed position was classified as bi-concave, biplanar, funnel/hemiconvex, and deformed. The disk position, translation and rotation were also measured. The difference between the shifted side and non-shifted side was analyzed by statistical analysis. Approximately 70% of the patients in the present study showed unilateral or bilateral ID. It was found that anterior disk displacements (ADD), especially rotational ADD, occurred more frequently in the shifted side, while normal disk position was observed mainly in the non-shifted side(p<0.01). The disk of the shifted side showed significantly deformed configuration and inferior-anterior disk position. However, the disk of the non-deviated side showed hyper-mobility during jaw opening movement. These results demonstrate that in FA patients, the disks status of the shifted side is different from that of the non-shifted side, a phenomenon that could be correlated to facial asymmetry.

Substituting oat hay or maize silage for portion of alfalfa hay affects growth performance, ruminal fermentation, and nutrient digestibility of weaned calves

Yang Zou,XinPing Zou,XiZhi Li,Gang Guo,Peng Ji,Yan Wang,ShengLi Li,YaJing Wang,ZhiJun Cao 아세아·태평양축산학회 2018 Animal Bioscience Vol.31 No.3

Objective: The impact of forage feeding strategy on growth performance, ruminal fermentation and nutrient digestibility in post-weaning calves was investigated. Methods: Forty-five female Holstein calves (body weight [BW] = 79.79±0.38 kg) were enrolled in the 35-d study at one week after weaning and randomly assigned to one of three dietary treatments. All diets were fed as total mixed ration containing 60% (dry matter [DM] basis) of basal starter feed and 40% (DM basis) of forage, but varied in composition of forage source including i) alfalfa (40% DM, AH); ii) alfalfa hay (26.7% DM)+oat hay (13.3% DM; OH); iii) alfalfa hay (26.7% DM)+corn silage (13.3% DM; WS). Results: Dry matter intake was not different among treatment groups (p>0.05). However, BW (p<0.05) and average daily gain (p<0.05) of calves fed AH and OH were greater than WS-fed calves, whereas heart girth was greater in OH-fed calves than those fed AH and WS (p<0.05). Ruminal fermentation parameters including proportion of butyric acid, acetated-to-propionate ratio, concentration of total volatile fatty acid, protozoal protein, bacterial protein, and microbial protein in rumen were the highest in OH (p<0.05) and the lowest in WS. Compared with the AH and WS, feeding oat hay to postweaning calves increased crude protein digestibility (p<0.05), and decreased duration of diarrhea (p<0.05) and fecal index (p<0.05). Conclusion: Our results suggested that partially replacing alfalfa hay with oat hay improved ruminal fermentation, nitrogen utilization, and reduced incidence of diarrhea in post-weaning dairy calves.

Prediction Role of Seven SNPs of DNA Repair Genes for Survival of Gastric Cancer Patients Receiving Chemotherapy

Zou, Hong-Zhi,Yang, Shu-Juan Asian Pacific Journal of Cancer Prevention 2012 Asian Pacific journal of cancer prevention Vol.13 No.12

We aimed to investigate DNA repair gene expression of response to chemotherapy among gastric patients, and roles in the prognosis of gastric cancer. A total of 209 gastric cancer patients were included in this study between January 2007 and December 2008, all treated with chemotherapy. Polymorphisms were detected by real time PCR with TaqMan probes, and genomic DNA was extracted from peripheral blood samples. The overall response rate was 61.2%. The median progression and overall survivals were 8.5 and 18.7 months, respectively. A significant increased treatment response was found among patients with XPG C/T+T/T or XRCC1 399G/A+A/A genotypes, with the OR (95% CI) of 2.14 (1.15-4.01) and 1.75 (1.04-3.35) respectively. We found XPG C/T+T/T and XRCC1 399 G/A+A/A were associated with a longer survival among gastric cancer patients when compared with their wide type genotypes, with HRs and 95% CIs of 0.49 (0.27-0.89) and 0.56 (0.29-0.98) respectively. Selecting specific chemotherapy based on pretreatment genotyping may be an innovative strategy for further studies.

Photocatalytic Generated Oxygen Species Properties by Fullerene Modified Two-Dimensional MoS₂ and Degradation of Ammonia Under Visible Light

Zou, Cong-Yang,Meng, Ze-Da,Zhao, Wei,Oh, Won-Chun Materials Research Society of Korea 2021 한국재료학회지 Vol.31 No.6

In this study, photocatalytic degradation of ammonia in petrochemical wastewater is investigated by solar light photocatalysis. Two-dimensional ultra-thin atomic layer structured MoS₂ are synthesized via a simple hydrothermal method. We examine all prepared samples by means of physical techniques, such as SEM-EDX, HRTEM, FT-IR, BET, XRD, XPS, DRS and PL. And, we use fullerene modified MoS₂ nanosheets to enhance the activity of photochemically generated oxygen (PGO) species. Surface area and pore volumes of the MoS₂-fullerene samples significantly increase due to the existence of MoS₂. And, PGO oxidation of MB, TBA and TMST, causing its concentration in aqueous solution to decrease, is confirmed by the results of PL. The generation of reactive oxygen species is detected through the oxidation reaction from 1,5-diphenyl carbazide (DPCI) to 1,5-diphenyl carbazone (DPCO). It is found that the photocurrent density and the PGO effect increase in the case with modified fullerene. The experimental results show that this heterogeneous catalyst has a degradation of 88.43% achieved through visible light irradiation. The product for the degradation of NH₃ is identified as N₂, but not NO^2- or NO^3-.

Theoretical Solutions for a Circular Opening in an Elastic–brittle–plastic Rock Mass Incorporating the Out-of-plane Stress and Seepage Force

Zou Jin-feng,Li Shuai-shuai,Xu Yuan,Dan Han-cheng,Zhao Lian-heng 대한토목학회 2016 KSCE JOURNAL OF CIVIL ENGINEERING Vol.20 No.2

Seepage force is simplified as seepage volumetric force in the stress field along the radial direction. Out-of-plane stress and seepage force are incorporated, and the theoretical solutions for stress, displacement, and plastic radius of a circular opening for the elastic-brittle-plastic and elastic-plastic rock mass are proposed based on the Mohr–Coulomb (MC) and generalized Hoek-Brown (HB) failure criteria. The presented solution and Wang’s solution (2012) are compared, and the corrected version of the proposed method is validated. Numerical examples of the proposed method based on the MC and generalized HB failure criteria reveal that the distributions of stress and displacement in the surrounding rock of the tunnel are significantly influenced by seepage force and out-ofplane stress. Displacement and plastic radius when seepage force and out-of-plane stress are considered are larger than those when the seepage force is not considered; the regulations of stress, however, run opposite. The results of displacement and plastic radius based on the generalized HB failure criterion are larger than those based on the MC failure criterion.

SIRT3-Mediated Dimerization of IDH2 Directs Cancer Cell Metabolism and Tumor Growth

Zou, Xianghui,Zhu, Yueming,Park, Seong-Hoon,Liu, Guoxiang,O'Brien, Joseph,Jiang, Haiyan,Gius, David American Association for Cancer Research 2017 Cancer research Vol.77 No.15

<P>These findings identify SIRT3 as a potential tumor suppressor, mediating its effects by limiting the ability of IDH2 to drive cancer cell metabolism and malignant progression.</P><P>The isocitrate dehydrogenase IDH2 produces α-ketoglutarate by oxidizing isocitrate, linking glucose metabolism to oxidative phosphorylation. In this study, we report that loss of SIRT3 increases acetylation of IDH2 at lysine 413 (IDH2-K413-Ac), thereby decreasing its enzymatic activity by reducing IDH2 dimer formation. Expressing a genetic acetylation mimetic IDH2 mutant (IDH2<SUP>K413Q</SUP>) in cancer cells decreased IDH2 dimerization and enzymatic activity and increased cellular reactive oxygen species and glycolysis, suggesting a shift in mitochondrial metabolism. Concurrently, overexpression of IDH2<SUP>K413Q</SUP> promoted cell transformation and tumorigenesis in nude mice, resulting in a tumor-permissive phenotype. IHC staining showed that IDH2 acetylation was elevated in high-risk luminal B patients relative to low-risk luminal A patients. Overall, these results suggest a potential relationship between SIRT3 enzymatic activity, IDH2-K413 acetylation-determined dimerization, and a cancer-permissive phenotype. <I>Cancer Res; 77(15); 3990–9. ©2017 AACR</I>.</P>
