Relationship between Mothers' Diagnosis of Cervical Cancer and Attitudes toward Preventing Cervical Cancer in Their Pubertal Daughters

PURPOSE: This study was conducted to examine the relationship between a mother's diagnosis of cervical cancer and attitudes toward cervical cancer prevention in their daughters. Their intention to recommend human papillomavirus (HPV) vaccination for their daughters, their confidence in 8 methods for cervical cancer prevention with their daughters, and their negative emotions about the assumption of their daughter's HPV infection. METHODS: This study was a secondary analysis of data from the study of maternal health beliefs about preventing cervical cancer. The study sample were women who reported whether ever diagnosed with cervical cancer, who had pubertal daughters (n=1,578). Data were analyzed by cross-tabulation analysis, Spearman's rank correlation analysis, and logistic regression. RESULTS: Mothers diagnosed with cervical cancer were more confident in using methods to prevent cervical cancer in their daughters (Z=−4.42, p<.001) and were more likely to feel negative emotions about the assumption of their daughters' HPV infection (Z=−2.44, p=.015) than mothers who were not diagnosed. Significant factors influencing their intention to recommend the HPV vaccination to their daughters were the mother's confidence in preventing cervical cancer in their daughters (odds ratio [OR], 1.003; 95% confidence interval [CI], 1.002–1.004) and their negative emotions about the assumption of their daughters' HPV infection (OR,1.016; 95% CI, 1.004–1.028). CONCLUSION: For the early prevention of cervical cancer in pubertal daughters, the education of their mothers should include interventions to increase confidence in preventing cervical cancer in their daughters and sensitivity of HPV infection toward daughters

Individual mean-variance relation and stock-level investor sentiment

This research studies the effect of stock-level investor sentiment on individual stock returns’ mean-variance relation. Using unique buy and sell volume data of retail investors in Korean stock market, we find that a positive mean-variance relation is undermined among high-sentiment stocks, but holds among low-sentiment stocks. We adopt buy-sell imbalances of retail investors for individual stocks as a measure of stock-level investor sentiment. Further, our findings provide empirical evidence of a strong riskreturn trade-off among stocks with low retail concentration (e.g., large capitalization, high-priced, and growth stocks). Existing research only analyzes market-wide investor sentiment. However, we study the effect of stock-level investor sentiment on individual stock returns. Therefore, our findings suggest novel implications about the investment strategy that the stock-level investor sentiment is important when constructing portfolios based on variance

Enhanced Electrochemical Performances of Hollow-Structured N-Doped Carbon Derived from a Zeolitic Imidazole Framework (ZIF-8) Coated by Polydopamine as an Anode for Lithium-Ion Batteries

Doping heteroatoms such as nitrogen (N) and boron (B) into the framework of carbon materials is one of the most efficient methods to improve the electrical performance of carbon-based electrodes. In this study, N-doped carbon has been facilely synthesized using a ZIF-8/polydopamine precursor. The polyhedral structure of ZIF-8 and the effective surface-coating capability of dopamine enabled the formation of N-doped carbon with a hollow structure. The ZIF-8 polyhedron served as a sacrificial template for hollow structures, and dopamine participated as a donor of the nitrogen element. When compared to ZIF-8-derived carbon, the HSNC electrode showed an improved reversible capacity of approximately 1398 mAh·g−1 after 100 cycles, with excellent cycling retention at a voltage range of 0.01 to 3.0 V using a current density of 0.1 A·g−1

Acute respiratory distress after metofluthrin insecticide ingestion in a 19-month-old girl

Metofluthrin is a volatile pyrethroid insecticide. Despite being widely used as a safe household insecticide, it could cause severe systemic symptoms. A 19-month-old girl was taken to the emergency department after ingesting 1 mL of a mosquito repellent containing metofluthrin. After the arrival, the girl developed respiratory distress, which worsened progressively despite the administration of oxygen with nebulized salbutamol and budesonide. Additionally, she underwent application of high-flow nasal cannula, and administration of activated charcoal and systemic steroids. Her dyspnea gradually improved, and she was thus discharged on day 4 with oral prednisolone. All medications were discontinued 10 days after the discharge without any complication. Respiratory distress can develop after the ingestion of even a small amount of metofluthrin. Symptomatic and adjunctive steroid therapies can be effective therapeutic options

Proteomics-based dissection of biotic stress responsive proteins in bread wheat (Triticum aestivum L.)

Proteomic techniques that allow the identification and quantification of stress-related proteins, mapping dynamics of their expression and post translational modifications represent an important approach in the research of plant stresses. Biotic stress is one of the major stresses limiting crop productivity and the geographical distribution of many important crops worldwide. Two hundred and seventeen protein spots reproducibly were detected from six gels by using two-dimensional electrophoresis. After tryptic digestion, MALDI-TOF/MS analysis and database searching of some of the identified proteins indicated that the proteins are known to be involved in several biotic stress related functions as disease associate with pathogens. Mass spectrometry analysis allowed the identification of 185 differential expressed proteins with isoforms including well known biotic stress  esponsive proteins. Keumgang (13%), Jinpum (8%), China-108 (14%), Yeonnon-67 (11%), Norin-61 (22%) and Kantou-107 (32%) were identified as biotic stress responses proteins directly coupled to disease and pathogen infection on wheat. Nevertheless, our studies provides new insights into identification of biotic stress responses protein in disease infected wheat grain by natural condition, the post-translational modification in  protein sequences, verify eventual differences among the genotypes in relation to them, and demonstrates the advantages of proteomic analysis.Key words: Biotic stress, matrix-assisted laser desorption ionization-time of flight, proteomics, posttranslational modification, two-dimensional electrophoresis, wheat

Schisandrae Fructus ethanol extract ameliorates inflammatory responses and articular cartilage damage in monosodium iodoacetate-induced osteoarthritis in rats

Schisandrae Fructus, the fruit of Schisandra chinensis (Turcz.) Baill., is widely used in traditional medicine for the treatment of a number of chronic diseases. Although, Schisandrae Fructus was recently reported to attenuate the interleukin (IL)-1β-induced inflammatory response in chondrocytes in vitro, its protective and therapeutic potential against osteoarthritis (OA) in an animal model remains unclear. Therefore, we investigated the effects of the ethanol extract of Schisandrae Fructus (SF) on inflammatory responses and cartilage degradation in a monosodium iodoacetate (MIA)-induced OA rat model. Our results demonstrated that administration with SF had a tendency to attenuate MIA-induced damage of articular cartilage as determined by a histological grade of OA. SF significantly suppressed the production of pro-inflammatory cytokines such as interleukin (IL)-1β, IL-6, and tumor necrosis factor-α in MIA-induced OA rats. SF also effectively inhibited expression of inducible nitric oxide (NO) synthase and cyclooxygenase-2, thereby inhibiting the release of NO and prostaglandin E2. In addition, the elevated levels of matrix metalloproteinases-13 and two biomarkers for diagnosis and progression of OA, such as cartilage oligomeric matrix protein and C-telopeptide of type II collagen, were markedly ameliorated by SF administration. These findings indicate that SF could be a potential candidate for the treatment of OA

The combined clinical impact of red blood cell distribution width and vascular calcification on cardiovascular events and mortality in patients with end-stage kidney disease

Background Little is known about how the interaction between red blood cell distribution width (RDW) and vascular calcification (VC) affects cardiovascular (CV) events and mortality in end-stage kidney disease (ESKD) patients. This study investigated the combined prognostic effect of RDW and VC in ESKD patients starting dialysis. Methods A retrospective single-center study of 582 ESKD patients was conducted. VC was assessed by calculating the aortic calcification index (ACI) using computed tomography. Patients were divided into low ACI-low RDW, low ACI-high RDW, high ACI-low RDW, and high ACI-high RDW groups based on median ACI (17.12) and RDW (14.3) values. The association between RDW and VC and the composite endpoint of CV events and death was analyzed. Results During a median follow-up of 3.1 years (range, 1.5–5.5 years), 165 CV events (28.4%) and 124 deaths (21.4%) occurred. Cox regression showed that the low ACI-high RDW (adjusted hazard ratio [HR], 1.66; 95% confidence interval [CI], 1.04–2.66; p = 0.03) and high ACI-low RDW (adjusted HR, 1.95; 95% CI, 1.21–3.14; p = 0.006) groups had a greater risk of CV events and death than the low ACI-low RDW group. The high ACI-high RDW group had the greatest risk (adjusted HR, 2.23; 95% CI, 1.42–3.52; p = 0.001). The effect of the interaction between ACI and RDW on CV events and mortality was statistically significant (p = 0.005). Conclusion High RDW and VC interact to increase the risk of CV events and death in ESKD patients
