Oral care during cancer treatment constitutes essential supportive care. We aimed to identify factors associated with cancer patients informing their family dentists about their cancer diagnosis. Using the generated original questionnaire, we conducted a cross-sectional questionnaire study in 500 cancer patients (gastric, colorectal, lung, breast, and prostate cancer) through the Internet from September 10 to 13, 2019. The factors influencing patients' disclosure of their cancer diagnosis to their family dentist were identified by multivariable logistic regression analysis. Nearly half of the respondents (42.2%) informed their family dentist that they had cancer. The disclosing behavior of cancer patients was distinctively associated with their physician's advice (odds ratio [OR] 59.3; 95% confidence interval [CI] 7.7–456.3); 8.6% of all respondents were advised to inform their dentist about their cancer diagnosis. In the group without the physician's advice, good relationship with family dentist was associated with disclosing behavior. This study indicates the need for support for cancer patients to receive appropriate oral care; patients' perceptions of the physician's advice and communication with the family dentist should be motivators for disclosing the cancer diagnosis to dentists. Medical workers involved in cancer care should demonstrate the benefit of medical-dental collaboration in cancer care of patients. [ABSTRACT FROM AUTHOR]

Background: The aim of this study was to assess the incidence of lung cancer and comorbidities in Korea and analyze the lung cancer patient's characteristics and their comorbidities over the past 12 years. This study also aimed to investigate factors related to death as treatment outcome in discharged lung cancer patients. Methods: This study analyzed the data obtained from the Korean National Hospital Discharge In-depth Injury Survey from 2006 to 2017. The quantity of discharged lung cancer patients was assessed by year. Comorbidities were limited to those included in the Elixhauser Comorbidity Index (ECI). A Chi-square test was performed to determine statistically significant differences in the distributions of the ECI and ECI scores according to the presence or absence of metastatic cancer. Logistic regression analysis was used to analyze factors related to death as treatment outcome. Results: From 2006 to 2017, the number of discharged male and female patients with lung cancer increased from 31,720 to 42,016 and 10,897 to 18,197, respectively. The increase in the number of lung cancer patients was greater in women than in men (67.0% vs. 32.5%, respectively). The most common associated comorbidities were hypertension, diabetes, and chronic pulmonary disease. The factors related to death as treatment outcome were found to include sex, admission route, number of hospital beds, length of stay, presence or absence of metastatic cancer, and ECI score. Conclusion: The number of lung cancer patients in Korea has increased, and a high proportion of these patients have chronic diseases, which negatively would impact the treatment and outcome of lung cancer patients as well as their quality of life. Thus, the management of chronic diseases needs to be prioritized in patients with lung cancer. [ABSTRACT FROM AUTHOR]

This study examines the cumulative effects of poverty on children's socio-emotional outcomes from ages 5 to 12, using U.S. National Longitudinal Survey of Youth data (N = 6941). Two definitions of poverty were used: absolute poverty as defined by the federal poverty threshold, and relative poverty defined as income less than 50 percent of median household income. (1) Does cumulative poverty, measured in absolute and relative terms, have any impact on children's socio-emotional outcomes? (2) Does this association increase/decrease as children become older? Relative poverty had a stronger adverse effect on children's social-emotional development than absolute poverty, and the adverse effect of relative poverty was bigger when children were older. Child and maternal characteristics affected children's socio-emotional development. The income threshold for absolute poverty is lower than that for relative poverty; using a relative poverty threshold might better identify individuals with limited resources that are at risk of having adverse socio-emotional outcomes.

Selenoproteins containing selenium in the form of selenocysteine are critical for bone remodeling. However, their underlying mechanism of action is not fully understood. Herein, we report the identification of selenoprotein W (SELENOW) through large-scale mRNA profiling of receptor activator of nuclear factor (NF)-κΒ ligand (RANKL)-induced osteoclast differentiation, as a protein that is downregulated via RANKL/RANK/tumour necrosis factor receptor-associated factor 6/p38 signaling. RNA-sequencing analysis revealed that SELENOW regulates osteoclastogenic genes. SELENOW overexpression enhances osteoclastogenesis in vitro via nuclear translocation of NF-κB and nuclear factor of activated T-cells cytoplasmic 1 mediated by 14-3-3γ, whereas its deficiency suppresses osteoclast formation. SELENOW-deficient and SELENOW-overexpressing mice exhibit high bone mass phenotype and osteoporosis, respectively. Ectopic SELENOW expression stimulates cell-cell fusion critical for osteoclast maturation as well as bone resorption. Thus, RANKL-dependent repression of SELENOW regulates osteoclast differentiation and blocks osteoporosis caused by overactive osteoclasts. These findings demonstrate a biological link between selenium and bone metabolism. Selenoproteins containing selenium have a variety of physiological functions including redox homeostasis and thyroid hormone metabolism. Here, the authors show that RANKL-dependent repression of selenoprotein W regulates cell fusion during osteoclast differentiation and bone remodelling in mice. [ABSTRACT FROM AUTHOR]

- Abstract
Using the National Longitudinal Survey of Youth 1997 (NLSY97) data, this study examines racial disparities in arrests for drug offending. Of the total 8984 NLSY97 participants, the study sample was restricted to the 4868 respondents who had ever reported using drugs (black = 1191, Hispanic = 980, white = 2697). The study questions are as follows: (1) Are there racial disparities in arrests for drug use, after controlling for incidence of drug use as well as other socio-demographic variables? (2) Are there racial disparities in arrests for drug dealing, after controlling for incidence of drug dealing as well as other socio-demographic variables? Compared with whites, blacks were more likely to be arrested for drug offending, even after controlling for incidence and other socio-demographic variables. Several socio-demographic variables, particularly gender, were also associated with arrests for drug offending. Bans on racial profiling and other legislative and policy changes are considered as potential strategies to ameliorate drug enforcement disparities. [ABSTRACT FROM AUTHOR]

Using the Longitudinal Study of Australian Children, this study examines the experiences of material hardships among Australian families with children and the role of social support in their experiences. The study sample includes 3939 children in the B-cohort (6 years old) and 4030 children in the K-cohort (10 years old). Cohort differences were observed in all analyses. The odds of experiencing material hardships were predicted by various factors apart from income. For both cohorts, material hardships had significant negative effects on maternal depression, which was a significant predictor of child outcomes. Even after controlling for income and other covariates, material hardships had significant negative effects on all outcomes of K-cohort children, but only on emotional functioning of B-cohort children. Social support was associated with the reduced odds of experiencing material hardships. Social support was also a significant predictor of all parental and child outcomes. However, the interaction effects showed that positive effects of such informal support were limited for families who already experienced material hardships. These findings suggest the importance of preventing material hardships in the first place. There is a significant role for public assistance in fulfilling the unmet needs of these families.

Using Head Start Impact Study Data, this study examines Head Start's impact on socio-emotional outcomes for children who have experienced violence or crime. The children were divided into two groups: children who had ever experienced violence or crime and those who had not. The baseline characteristics for children, effects of violence on children, and the moderation effects of Head Start were examined. Child and family risk factors were associated with more experience of violence or crime, which negatively affected their socio-emotional outcomes. This was more prevalent for children living in rural areas and for White children. Enrollment in Head Start was positively associated with children's socio-emotional outcomes, with greater impact on those who had ever experienced violence or crime. [ABSTRACT FROM AUTHOR]

- Abstract
The discovery of the human genome and subsequent expansion of proteomics research combined with emerging technologies such as sophisticated computational biology are producing unprecedented changes in our understanding of the role of tumor suppressors in cell signaling. p53, a key tumor suppressor gene, is mutated in the majority of human cancers. Successful outcome of chemotherapy and radiotherapy, in many cases, depends on functional p53. Therefore, elucidation of the function, regulation, and molecular interactions of p53 with its targets is of great importance for developing successful cancer therapy. Because p53 is a transcription factor with an expanded repertoire of genes that are known to be directly or indirectly under its control, global analysis of gene expression profiles represents the best approach for studying the p53 response to chemotherapeutic agents. Our laboratory and others have used gene expression profiling with microarrays to isolate p53 target genes in an attempt to understand the molecular signaling of p53 and to determine the molecular consequences that follow from treatment of cancer cells with chemotherapeutic agents. Although these attempts have been successful in isolating novel genes, gene expression profiling alone at the transcription level is not sufficient. Most of pharmacological targets are proteins or DNA, not RNA. Therefore, we need an approach that focuses on the molecular profiling of cancer cells at the DNA, RNA, and proteins. In this chapter, key findings on the current genomics and proteomics approaches for isolating p53 targets and their functional analysis are reviewed, and perspective is provided on the potential of integrating both approaches in the molecular pharmacology of p53 signaling.

- Abstract
Ad hoc network is the network which can be considered without a pre-constructed infrastructure, and a mobile node can join the network freely. However, the participation of the mobile nodes to the ad hoc network brings up much burden of re-computation for new routes, because it leads to losing the connection frequently. Therefore, it needs authentication against the mobile nodes. To make that possible, we have two methods: single Certificate Authority(CA) and distributed CA. In the case of single CA method, the wireless network can be collapsed owing to expose the CA, but still the distributed CA method is a little safer than previous one because it needs attacks toward a lot of CAs to collapse the network. We can consider secret sharing scheme as the method that constructs the distributed CA system, but it is weak when the network size is too large. In this paper, we suggest hierarchical structure for the authentication method, and show the results of simulation. Keywords: Ad Hoc Network Security, Authentication, Certificate Issuing.

- Abstract
Though authentication using biometric techniques has conveniences for people, security problems like the leakage of personal bio-information would be serious. Even if cancelable biometric is a good solution for the problems, only a few biometric authentication scheme with cancelable feature has been published. In this paper, we suggest a face authentication scheme with two security factors: password and face image. Using matching algorithm in the permuted domain, our scheme is designed to be cancelable in the sense that templates that is composed of permutation and weight vector can be changed freely.

- Abstract
Home Server plays an important role to manage all home network devices and multimedia content services in the digital home. Multimedia collaboration over home networking devices is inhibited by several factors. The decision based on a single input agent to serve all the needs of the home users is to be enhanced to facilitate multi-modal inputs with multiple integrated User Agents working together to facilitate the new generation of dynamic home networking devices. Display has to be adaptive and context sensitive to adapt to the dynamic needs of the user. In this paper, we present a hybrid architectural framework as our recent efforts for extending the functionalities of Home Server in order to support multi-modal context-sensitive multimedia collaboration services.

Lee, Kyunghee, Kim, Youn, and Shin, Kyusoon
- Abstract
Here we present a simple process to synthesize artificial water-repellent leaf structures through the introduction of hierarchical nanostructures to the surface using anodized aluminum oxide templates. Unlike cylindrical nanopores fabricated by conventional anodization, biomimetic hierarchical structures were manufactured by multi-step anodization of nanoscopically pre-patterned Al. From the hierarchical anodized aluminum oxide templates, the perfluoropolyether nanostructures were simply replicated and repeatedly obtained by reusing the anodized aluminum oxide templates without anti-adhesion coating. Upon the investigation of the wettability of perfluoropolyether hierarchical surfaces, it was found that the surface became more hydrophobic (∼152°) with the increase of the structural complexity, and are comparable to water-repellent leaf surfaces found in nature.

Mitogen-activated protein kinases (MAPKs or MPKs) are one of the most important and conserved signaling molecules in plants. MPKs can directly modulate gene expression by the phosphorylation of transcription factors. However, only a few target substrates of MPKs have been isolated. Here, we identified a CH-type zinc finger transcription factor from Arabidopsis, ZAT10, as a substrate of MPKs. Using in vitro and in vivo protein-protein interaction analyses, we demonstrated that ZAT10 directly interacted with MPK3 and MPK6. ZAT10 was phosphorylated by recombinant Arabidopsis MPK3 and MPK6 in a kinase assay. Furthermore, ZAT10 was also phosphorylated by native MPK3 and MPK6 prepared from Arabidopsis plants in an in-gel kinase assay. Mass spectrometry analysis of phosphopeptides was used to determine two MPK phosphorylation sites in ZAT10. These sites were verified by site-directed mutagenesis and in vitro kinase assays.

- Abstract
To assess the recovery effect of water-soluble components of nacre on wound healing of burns, water-soluble nacre (WSN) was obtained from powdered nacre. Alterations to WSN-mediated wound healing characteristics were examined in porcine skin with deep second-degree burns; porcine skin was used as a proxy for human. When WSN was applied to a burned area, the burn-induced granulation sites were rapidly filled with collagen, and the damaged dermis and epidermis were restored to the appearance of normal skin. WSN enhanced wound healing recovery properties for burn-induced apoptotic and necrotic cellular damage and spurred angiogenesis. Additionally, WSN-treated murine fibroblast NIH3T3 cells showed increased proliferation and collagen synthesis. Collectively, the findings indicate that WSN improves the process of wound healing in burns by expeditiously restoring angiogenesis and fibroblast activity. WSN may be useful as a therapeutic agent, with superior biocompatibility to powdered nacre, and evoking less discomfort when applied to a wounded area. [ABSTRACT FROM AUTHOR]

idopsis MAP kinase phosphatase 1 (AtMKP1) is a member of the mitogen-activated protein kinase (MPK) phosphatase family, which negatively regulates AtMPKs. We have previously shown that AtMKP1 is regulated by calmodulin (CaM). Here, we examined the phosphorylation of AtMKP1 by its substrate AtMPK6. Intriguingly, AtMKP1 was phosphorylated by AtMPK6, one of AtMKP1 substrates. Four phosphorylation sites were identified by phosphoamino acid analysis, TiO chromatography and mass spectrometric analysis. Site-directed mutation of these residues in AtMKP1 abolished the phosphorylation by AtMPK6. In addition, AtMKP1 interacted with AtMPK6 as demonstrated by the yeast two-hybrid system. Finally, the phosphatase activity of AtMKP1 increased approximately twofold following phosphorylation by AtMPK6. By in-gel kinase assays, we showed that AtMKP1 could be rapidly phosphorylated by AtMPK6 in plants. Our results suggest that the catalytic activity of AtMKP1 in plants can be regulated not only by Ca/CaM, but also by its physiological substrate, AtMPK6. [ABSTRACT FROM AUTHOR]

- Abstract
Eight toluene-sensitive mutants were previously isolated from the toluene-tolerant bacterium Pseudomonas putida GM730. One of these mutants was TOS6, in which Tn5 had been inserted into phoU. Susceptibility to multiple antibiotics, as well as toluene sensitivity, was increased in the phoU mutant of P. putida GM730. We compared the outer membrane proteins from the phoU mutant and wild-type via two-dimensional gel electrophoresis. A 45 kDa protein was dramatically overexpressed as the result of phoU inactivation, and this protein was identified by peptide mass fingerprinting and microsequencing as a conserved hypothetical protein consisting of 414 amino acids. The protein, designated as OprT, harbors a signal sequence and extended β-sheets, both of which are features common to the bacterial porins. The rate of ethidium bromide accumulation in TOS6 was higher than in GM730, which indicates that the TOS6 membranes may be more permeable to ethidium bromide than are the membranes of GM730. We propose that the toluene sensitivity and increased antibiotic susceptibility observed in the phoU mutant may be attributable to increased membrane permeability. [ABSTRACT FROM AUTHOR]

- Abstract
We demonstrate that the nanoscopic block copolymer patterns on GaN can enhance light extraction efficiency of GaN-based light emitting diodes. Nanoporous patterns were fabricated on a bare GaN substrate via self-assembly of poly(styrene- b-methyl methacrylate) block copolymers from which PMMA microdomains were selectively removed later on. A bare GaN surface was treated with a photo-crosslinkable thin layer of poly(styrene- r-methyl methacrylate) random copolymers to tune the cylindrical microdomain orientations. The nanoporous block copolymer thin film was controlled to be thicker than its typical repeat period in bulk by incorporating PMMA homopolymer into block copolymer. Consequently, the light extraction efficiency in photoluminescence spectra could be tuned with the thickness of nanopatterned thin film on GaN. [ABSTRACT FROM AUTHOR]

In this study, I report secondary analyses using data from the Infant Health and Development Program (IHDP). The IHDP included parent-targeted as well as child-targeted components as an integral part of early intervention programs. I examined three questions: (1) Do the IHDP early intervention services enhance adaptive maternal coping skills? (2) Do maternal coping skills moderate the relationship between stressful life events and maternal depression? (3) Are maternal coping skills associated with children's behavioral scores? Mothers in the treatment group have more adaptive coping skills than follow-up only mothers, and these effects are moderated by maternal characteristics. Adaptive coping skills moderate the effects of negative life events on maternal depression. Adaptive maternal coping skills are significantly associated with fewer behavioral problems for children at age three. These effects are moderated by the intervention. Implications for early intervention programs are discussed. [ABSTRACT FROM AUTHOR]

The polyketide antibiotic 2,4-diacetylphloroglucinol (DAPG) is a phenolic secondary metabolite produced by
Pseudomonas spp. that serves as a biocontrol agent. DAPG is known to inhibit root growth and seed germination in plants. However, the effects of DAPG on leaf growth have not been elucidated yet. In this study, we found that applying DAPG at concentration above 30 µM suppresses the development ofArabidopsis leaves. Using an integrated proteomic analysis approach, we investigated the physio-molecular responses ofArabidopsis leaves under 10–100 µM DAPG treatment. Two-dimensional electrophoresis (2-DE)-based proteomic analysis identified 46 differentially expressed spots with at least a twofold change, corresponding to 37 proteins involved in stress and defense, metabolism, photosynthesis, and carbohydrate metabolism processes. Furthermore, we found that the expressions of stress and defense-related proteins were upregulated in response to DAPG, while those of photosynthesis-related proteins were downregulated. Additionally, RT-PCR result showed that the identified DAPG-responsive proteins in the proteomic analysis were similarly regulated at the transcriptional level. Collectively, our findings provide insights into the molecular mechanism of the response to DAPG inArabidopsis leaves. [ABSTRACT FROM AUTHOR]- Published
