Waterlogging is one of the major environmental challenges that can adversely impact squash growth, development, and productivity. Nevertheless, studies on the physiological changes of squash to waterlogging stress are scarce. Previously, we reported that the Cucurbita moschata (Cmo) Early Price (Ep) cultivar showed higher chlorophyll content (CC) and spectral refl ectance compared to the Cucurbita maxima (Cma) OK-101 (Ok) cultivar after waterlogging. In the present work, we further examined more physiological parameters in eight cultivars of Cmo and Cma, and studied whether these non-destruc tive indices could effi ciently identify various waterlogging-tolerant genotypes and were consistent with visual evaluations. Moreover, we investigated the eff ects of waterlogging on the antioxidant system of cucurbit species, and evaluated dynamic changes occurring in these plants during varying waterlog periods by determining physiological characteristics. The activ ity of ascorbate peroxidase (APX) and superoxide dismutase (SOD) showed a signifi cant increase in Ep plant leaves and roots after 72 h and 6 h of waterlogging, respectively, compared to Ok plants. In addition, Ep exhibited a higher tolerance to waterlogging than Ok in terms of enhanced root length, values in CC, spectral refl ectance, and APX and SOD activity, plus decreased levels of electrolyte leakage, 2,2-diphenyl-1-picrylhydrazyl free radical scavenging, and hydrogen peroxide levels. This study provides a comprehensive understanding of the physiological variations in response to waterlogging stress and can potentially be used to breed cucurbit species with waterlogging tolerance for a wetter future climate.

Lin, Hui-Chen,Lin, Wen-Chuan,Lee, Tzu-Ying,Lin, Hung-Ru Asian Pacific Journal of Cancer Prevention 2013 Asian Pacific journal of cancer prevention Vol.14 No.1

Background: Cancer is the leading cause of death in Taiwan. Spouses are generally the main caregivers of affectyed patients but previous studies have seldom investigated the needs of male spouses of patients with metastatic cancer. Purpose: To explore the lived experiences of such male spouses. Methods: A qualitative design using in-depth interviewswasconducted with male spouses of patients with metastatic cancer being treated at the oncology outpatient department in a teaching hospital in northern Taiwan. Results: Nine participants aged 31-78 were interviewed. Content analysis of the interviews revealed five themes: suffering and struggling, difficulty in focusing on communication and interaction, shouldering responsibility, cherishing the love between husband and wife, and enabling each other to live better. This study demonstrated how male spousse experienced physical and psychological suffering when their wives suffered from metastatic cancer. They had to bear the pain of their wife's suffering, and also had to shoulder the responsibility for everything. All their efforts were put towards enabling each other to live a better life. They cherished the rest of the time they could spend with their wives, even though they had to live a hard life. As the male spouses of patients with metastatic cancer, the participants exhibited both the masculinity of men and the ability to express care and tenderness. Conclusions: The results showed that male spouses need more attention in terms of communication and bearing with suffering. Health care professionals should more actively understand the needs and provide assistance when facing the male spouse of patients with cancer, so as make sure that they possess the ability to take care of their wives. Health care professionals should also assist and properly act as a bridge of communication between husbands and wives.

Background: This study aimed to establish a nomogram by combining clinicopathologic factors with overall survival of stage IA-IIB cervical cancer patients after complete resection with pelvic lymphadenectomy. Materials and Methods: This nomogram was based on a retrospective study on 1,563 stage IA-IIB cervical cancer patients who underwent complete resection and lymphadenectomy from 2002 to 2008. The nomogram was constructed based on multivariate analysis using Cox proportional hazard regression. The accuracy and discriminative ability of the nomogram were measured by concordance index (C-index) and calibration curve. Results: Multivariate analysis identified lymph node metastasis (LNM), lymph-vascular space invasion (LVSI), stromal invasion, parametrial invasion, tumor diameter and histology as independent prognostic factors associated with cervical cancer survival. These factors were selected for construction of the nomogram. The C-index of the nomogram was 0.71 (95% CI, 0.65 to 0.77), and calibration of the nomogram showed good agreement between the 5-year predicted survival and the actual observation. Conclusions: We developed a nomogram predicting 5-year overall survival of surgically treated stage IA-IIB cervical cancer patients. More comprehensive information that is provided by this nomogram could provide further insight into personalized therapy selection.

Chung Mei-Hua,Hung Kuo-Hsiang,Ma Mi-Chia,Liu Mei-Yu,Lin Ru-Wei 한국산업안전보건공단 산업안전보건연구원 2024 Safety and health at work Vol.15 No.1

Numerous studies have indicated that organic fertilizers (OFer) might contain heavy metals (HMs) that present health risks to organic farmers (OFar). This study compared the concentrations of six HMs (Zn, Ni, Cd, Cu, Pb, Cr) in the blood of two distinct groups of farmers: 30 OFar from a designated organic area in eastern Taiwan, and 74 conventional farmers (CFar) from neighboring non-organic designated regions. The findings revealed that the OFar exhibited higher levels of Zn (1202.70 ± 188.74 μg/L), Cr (0.20 ± 0.09 μg/L), and Ni (2.14 ± 1.48 μg/L) in their blood compared to the CFar (988.40 ± 163.16 μg/L, 0.18 ± 0.15 μg/L, and 0.77 ± 1.23 μg/L), respectively. The disparities in Zn, Cr, and Ni levels were measured at 214.3 μg/L, 0.02 μg/L, and 1.37 μg/L, respectively. Furthermore, among the OFar, those who utilized green manures (GM) displayed significantly elevated blood levels of Zn (1279.93 ± 156.30 μg/L), Cr (0.24 ± 0.11 μg/L), and Ni (1.94 ± 1.38 μg/L) compared to individuals who exclusively employed chemical fertilizers (CFer) (975.42 ± 165.35 μg/L, 0.19 ± 0.16 μg/L, and 0.74 ± 1.20 μg/L), respectively. The differences in Zn, Cr, and Ni levels were measured at 304.51 μg/L, 0.05 μg/L, and 1.20 μg/L, respectively. As a result, OFar should be careful in choosing OFer and avoid those that may have heavy metal contamination.

Taiwanese Parents’ Experience of Making a “Do Not Resuscitate” Decision for Their Child in Pediatric Intensive Care Unit

Shu-Mei Liu,Hung-Ru Lin,Frank L. Lu,Tzu-Ying Lee 한국간호과학회 2014 Asian Nursing Research Vol.8 No.1

Purpose: The purpose of this project was to explore the parental experience of making a “do not resuscitate” (DNR) decision for their child who is or was cared for in a pediatric intensive care unit in Taiwan. Methods: A descriptive qualitative study was conducted following parental signing of a standard hospital DNR form on behalf of their critically ill child. Sixteen Taiwanese parents of 11 children aged 1 month to 18 years were interviewed. Interviews were recorded, transcribed, analyzed and sorted into themes by the sole interviewer plus other researchers. Results: Three major themes were identified: (a) “convincing points to sign”, (b) “feelings immediately after signing”, and (c) “postsigning relief or regret”. Feelings following signing the DNR form were mixed and included “frustration”, “guilt”, and “conflicting hope”. Parents adjusted their attitudes to thoughts such as “I have done my best,” and “the child’s life is beyond my control.” Some parents whose child had died before the time of the interview expressed among other things “regret not having enough time to be with and talk to my child”. Conclusion: Open family visiting hours plus staff sensitivity and communication skills training are needed. To help parents with this difficult signing process, nurses and other professionals in the pediatric intensive care unit need education on initiating the conversation, guiding the parents in expressing their fears, and providing continuing support to parents and children throughout the child’s end of life process.

Dynamics of rate of returns for postgraduate education in Taiwan: the impact of higher education expansion

Chih-Hai Yang,Chun-Hung A. Lin,Chien-Ru Lin 서울대학교 교육연구소 2011 Asia Pacific Education Review Vol.12 No.3

This paper analyzes the dynamics of rate of returns for postgraduate education and the determinants of wage premiums for postgraduate labor, especially for the impact of higher education expansions, in terms of quantity and quality, since the late 1990s in Taiwan. Utilizing quasi-panel data over the 1990-2004 period and employing the double fixed effect model, the empirical results first confirm the existence of wage premiums for workers with postgraduate degrees. However, the analysis on the dynamics of wage premiums finds that it ranged from only 1.40 to 11.67% and decreased sharply in 2004, indicating that the pecuniary reward for postgraduate qualification seems not to be as high as expected. Along with the rapid expansion of higher education, the concern about its negative impact on rate of returns to education is witnessed in this study. The sharp increase in the supply of postgraduate labors appears to have a negative impact on an individual's wage premium. Similarly, a decline in the postgraduate labor quality along with higher education expansion has contributed to a negative wage effect.

Han-Lu Gao,Xuan Wang,Hong-Ru Sun,Jun-De Zhou,Shang-Qun Lin,Yu-Hang Xing,Lin Zhu,Hai-Bo Zhou,Ya-Shuang Zhao,Qiang Chi,Yu-Peng Liu 거트앤리버 소화기연관학회협의회 2018 Gut and Liver Vol.12 No.2

Background/Aims: Methylation status plays a causal role in carcinogenesis in targeted tissues. However, the relationship between the DNA methylation status of multiple genes in blood leukocytes and colorectal cancer (CRC) susceptibility as well as interactions between dietary factors and CRC risks are unclear. Methods: We performed a case-control study with 466 CRC patients and 507 cancer-free controls to investigate the association among the methylation status of individual genes, multiple CpG site methylation (MCSM), multiple CpG site heterogeneous methylation and CRC susceptibility. Peripheral blood DNA methylation levels were detected by performing methylation-sensitive high-resolution melting. Results: Total heterogeneous methylation of CA10 and WT1 conferred a significantly higher risk of CRC (adjusted odds ratio [ORadjusted], 5.445; 95% confidence interval [CI], 3.075 to 9.643; ORadjusted, 1.831; 95% CI, 1.100 to 3.047; respectively). Subjects with high-level MCSM (MCSM-H) status demonstrated a higher risk of CRC (ORadjusted, 4.318; 95% CI, 1.529 to 12.197). Additionally, interactions between the high-level intake of fruit and CRH, WT1, and MCSM on CRC were statistically significant. Conclusions: The gene methylation status of blood leukocytes may be associated with CRC risk. MCSM-H of blood leukocytes was associated with CRC, especially in younger people. Some dietary factors may affect hypermethylation status and influence susceptibility to CRC.
