Background: The E2F members have been divided into transcription activators (E2F1-E2F3) and repressors (E2F4-E2F8). E2F8 with E2F7 has been known to play an important physiologic role in embryonic development and cell cycle regulation by repressing E2F1. However, the function of E2F8 in cancer cells is unknown. Methods: E2F8 expression was assessed by immunoblotting or immunofluorescence staining in human lung cancer (LC) cells and tissues from LC patients (n = 45). Cell proliferation, colony formation, and invasion analysis were performed to evaluate the role of E2F8 in LC. Microarray analysis was used to determine the target genes of E2F8. The regulation of E2F8 on the expression of ubiquitin-like PHD and RING domain-containing 1 (UHRF1), one of E2F8 target genes, was determined using chromatin immunoprecipitation and promoter activity assays. Human LC xenograft models were used to determine the effects of inhibiting E2F8 by siRNAs (n = 7 per group) or antisense morpholino (n = 8 per group) on tumor growth. Survival was analyzed using the Kaplan-Meier method and group differences by the Student’s t test. All statistical tests were two-sided. Results: LC tumors overexpressed E2F8 compared with normal lung tissues. Depletion of E2F8 inhibited cell proliferation and tumor growth. E2F8 knockdown statistically significantly reduced the expression of UHRF1 (~60%-70%, P < .001), and the direct binding of E2F8 on the promoter of UHRF1 was identified. Kaplan-Meier analysis with a public database showed prognostic significance of aberrant E2F8 expression in LC (HR = 1.91 95% CI = 1.21 to 3.01 in chemo-naïve patients, P = .0047). Conclusions: We demonstrated that E2F8 is overexpressed in LC and is required for the growth of LC cells. These findings implicate E2F8 as a novel therapeutic target for LC treatment. PMID:26089541

Melanoma is the most common primary malignant neoplasm in adults, causing more deaths than any other skin cancer, necessitating the development of new target-based approaches. Current evidence suggests SIRT1, the mammalian nicotinamide adenine dinucleotide (NAD + )-dependent protein deacetylase, and nicotinamide phosphoribosyltransferase (NAMPT), the rate-limiting NAD + biosynthetic enzyme, together comprise a novel systemic regulatory network to play a pivotal role in cell proliferation and apoptosis. Nevertheless, how the regulation of this cofactor interfaces with signal transduction network remains poorly understood in melanoma. Here, we report NAMPT is highly expressed in melanomaassociated with poor overall survival in patients. Pharmacological and genetic inhibition of NAMPT decreased NAD + levels and melanoma cell proliferation capacity, and NAMPT knockdown induced apoptosis through the activity of the tumor suppressor p53. Next, we demonstrate NAMPT regulates the transcription factor E2F family member 2 (E2F2) in the apoptosis process. Downstream, E2F2 control the mRNA and protein levels of SIRT1. Finally, we find NAMPT mediates the apoptosis resistance of melanoma cells through NAMPT-E2F2-SIRT1 axis, more than NAD + -driven transcriptional program. Accordingly, our results demonstrated that NAMPT is a prognostic marker in melanoma, and the identificationofNAMPT-E2F2-SIRT1 pathway establishes another link between NAMPT and apoptosis events in melanoma, with therapeutic implications for this deadly cancer.

Attacking Cancer’s Achilles Heel: Antagonism of Anti-Apoptotic BCL-2 Family Members

PubMed Central

Opferman, Joseph T.

2015-01-01

Malignant cells routinely violate cellular checkpoints that should initiate cell death in normal cells by triggering pro-apoptotic members of the BCL-2 family of proteins. To escape such death inducing signals, cancer cells often select for up regulation of anti-apoptotic BCL-2 family members including BCL-2, BCL-XL, BFL-1, BCL-W, and MCL-1. These family members prevent death by sequestering pro-apoptotic molecules. To counter this resistance mechanism, small molecule inhibitors of anti-apoptotic BCL-2 family members have been under development. These molecules have shown promise in pre-clinical and clinical testing to overcome apoptotic resistance, prompting cancer cells to undergo apoptosis. Alternatively, other strategies have taken advantage of the normal regulatory machinery controlling anti-apoptotic molecules and have used inhibitors of signaling pathways to down-modulate the expression of anti-apoptotic molecules thus tilting the balance in cancer cells to cell death. This review explores recent developments and strategies aimed at antagonizing anti-apoptotic BCL-2 family member action to promote the induction of cell death in cancer therapy. PMID:26293580

E2F1 and E2F2 prevent replicative stress and subsequent p53-dependent organ involution.

Tissue homeostasis requires tight regulation of cellular proliferation, differentiation and apoptosis. E2F1 and E2F2 transcription factors share a critical role in tissue homeostasis, since their combined inactivation results in overall organ involution, specially affecting the pancreatic gland, which subsequently triggers diabetes. We have examined the mechanism by which these E2Fs regulate tissue homeostasis. We show that pancreas atrophy in E2F1/E2F2 double-knockout (DKO) mice is associated with mitochondrial apoptosis and activation of the p53 pathway in young animals, before the development of diabetes. A deregulated expression of E2F target genes was detected in pancreatic cells of young DKO animals, along with unscheduled DNA replication and activation of a DNA damage response. Importantly, suppression of DNA replication in vivo with aphidicolin led to a significant inhibition of the p53 pathway in DKO pancreas, implying a causal link between DNA replication stress and p53 activation in this model. We further show that activation of the p53 pathway has a key role in the aberrant phenotype of DKO mice, since targeted inactivation of p53 gene abrogated cellular apoptosis and prevented organ involution and insulin-dependent diabetes in mice lacking E2F1/E2F2. Unexpectedly, p53 inactivation unmasked oncogenic features of E2F1/E2F2-depleted cells, as evidenced by an accelerated tumor development in triple-knockout mice compared with p53(-/-) mice. Collectively, our data reveal a role for E2F1 and E2F2 as suppressors of replicative stress in differentiating cells, and uncover the existence of a robust E2F-p53 regulatory axis to enable tissue homeostasis and prevent tumorigenesis. These findings have implications in the design of approaches targeting E2F for cancer therapy.

Tandem E2F Binding Sites in the Promoter of the p107 Cell Cycle Regulator Control p107 Expression and Its Cellular Functions

The retinoblastoma tumor suppressor (Rb) is a potent and ubiquitously expressed cell cycle regulator, but patients with a germline Rb mutation develop a very specific tumor spectrum. This surprising observation raises the possibility that mechanisms that compensate for loss of Rb function are present or activated in many cell types. In particular, p107, a protein related to Rb, has been shown to functionally overlap for loss of Rb in several cellular contexts. To investigate the mechanisms underlying this functional redundancy between Rb and p107 in vivo, we used gene targeting in embryonic stem cells to engineer point mutations in two consensus E2F binding sites in the endogenous p107 promoter. Analysis of normal and mutant cells by gene expression and chromatin immunoprecipitation assays showed that members of the Rb and E2F families directly bound these two sites. Furthermore, we found that these two E2F sites controlled both the repression of p107 in quiescent cells and also its activation in cycling cells, as well as in Rb mutant cells. Cell cycle assays further indicated that activation of p107 transcription during S phase through the two E2F binding sites was critical for controlled cell cycle progression, uncovering a specific role for p107 to slow proliferation in mammalian cells. Direct transcriptional repression of p107 by Rb and E2F family members provides a molecular mechanism for a critical negative feedback loop during cell cycle progression and tumorigenesis. These experiments also suggest novel therapeutic strategies to increase the p107 levels in tumor cells. PMID:20585628

Sleep, anxiety and fatigue in family members of patients admitted to the intensive care unit: a questionnaire study

PubMed Central

2013-01-01

Introduction Family members of critically ill patients often experience increased incidence of physical and mental health issues. One of the first ways family members suffer is by losing sleep. The purpose of this study is to understand sleep quality, levels of fatigue and anxiety, and factors contributing to poor sleep in adult family members of critically ill patients. Methods A questionnaire was designed to evaluate sleep, fatigue and anxiety during the intensive care unit (ICU) admission. We incorporated three validated instruments: General Sleep Disturbance Scale (GSDS), Beck Anxiety Index (BAI) and Lee Fatigue Scale (NRS-F). Adult family members of patients in ICU for more than 24 hours were approached for questionnaire completion. Patient demographics were recorded. Results The study population consisted of 94 respondents, (49.1 ± 12.9 years, 52.7% male); 43.6% were children and 21.3% were spouses of ICU patients. Sleep quality was rated as poor/very poor by 43.5% of respondents, and good/very good by 15.2%. The most common factors contributing to poor sleep were anxiety (43.6%), tension (28.7%) and fear (24.5%). Respondents' most common suggestions to improve sleep were more information regarding the patient's health (24.5%) and relaxation techniques (21.3%). Mean GSDS score was 38.2 ± 19.3, with 58.1% of respondents experiencing moderate to severe sleep disturbance. Mean BAI was 12.3 ± 10.2, with 20.7% of respondents experiencing moderate to severe anxiety. Mean NRS-F was 3.8 ± 2.5, with 57.6% of respondents experiencing moderate to high fatigue. Family members who spent one or more nights in the hospital had significantly higher GSDS, BAI and NRS-F scores. The patient's Acute Physiology and Chronic Health Evaluation (APACHE) II score at survey completion correlated significantly with family members' GSDS, BAI and NRS-F. Conclusion The majority of family members of ICU patients experience moderate to severe sleep disturbance and fatigue, and mild

A novel IL-1 family member (nIL-1F) has been discovered in fish, adding a further member to this cytokine family. The unique gene organization of nIL-1F, together with its location in the genome and low homology to known family members, suggests that this molecule is not homologous to known IL-1F. Nevertheless, it contains a predicted C-terminal beta-trefoil structure, an IL-1F signature region within the final exon, a potential IL-1 converting enzyme cut site, and its expression level is clearly increased following infection, or stimulation of macrophages with LPS or IL-1beta. A thrombin cut site is also present and may have functional relevance. The C-terminal recombinant protein antagonized the effects of rainbow trout rIL-1beta on inflammatory gene expression in a trout macrophage cell line, suggesting it is an IL-1beta antagonist. Modeling studies confirmed that nIL-1F has the potential to bind to the trout IL-1RI receptor protein, and may be a novel IL-1 receptor antagonist.

Deployment affects not just the service members, but also their family members back home. Accordingly, this study examined how resilient family processes during a deployment (i.e., frequency of communication and household management) were related to the personal reintegration of each family member (i.e., how well each family member begins to "feel like oneself again" after a deployment), as well as several indicators of subjective well-being. Drawing from the family attachment network model (Riggs & Riggs, 2011), the present study collected survey data from 273 service members, their partners, and their adolescent children. Resilient family processes during the deployment itself (i.e., frequency of communication, household management), postdeployment positive and negative personal reintegration, and several indicators of well-being were assessed. Frequency of communication was related to personal reintegration for service members, while household management was related to personal reintegration for nondeployed partners; both factors were related to personal reintegration for adolescents. Negative and positive personal reintegration related to a variety of subjective well-being outcomes for each individual family member. Interindividual (i.e., crossover) effects were also found, particularly between adolescents and nondeployed partners. (PsycINFO Database Record (c) 2018 APA, all rights reserved).

E2F function in muscle growth is necessary and sufficient for viability in Drosophila

2016-01-01

The E2F transcription factor is a key cell cycle regulator. However, the inactivation of the entire E2F family in Drosophila is permissive throughout most of animal development until pupation when lethality occurs. Here we show that E2F function in the adult skeletal muscle is essential for animal viability since providing E2F function in muscles rescues the lethality of the whole-body E2F-deficient animals. Muscle-specific loss of E2F results in a significant reduction in muscle mass and thinner myofibrils. We demonstrate that E2F is dispensable for proliferation of muscle progenitor cells, but is required during late myogenesis to directly control the expression of a set of muscle-specific genes. Interestingly, E2f1 provides a major contribution to the regulation of myogenic function, while E2f2 appears to be less important. These findings identify a key function of E2F in skeletal muscle required for animal viability, and illustrate how the cell cycle regulator is repurposed in post-mitotic cells. PMID:26823289

The Aryl Hydrocarbon Receptor Binds to E2F1 and Inhibits E2F1-induced Apoptosis

Cellular stress by DNA damage induces checkpoint kinase-2 (CHK2)-mediated phosphorylation and stabilization of the E2F1 transcription factor, leading to induction of apoptosis by activation of a subset of proapoptotic E2F1 target genes, including Apaf1 and p73. This report characterizes an interaction between the aryl hydrocarbon (Ah) receptor (AHR), a ligand-activated transcription factor, and E2F1 that results in the attenuation of E2F1-mediated apoptosis. In Ahr−/− fibroblasts stably transfected with a doxycycline-regulated AHR expression vector, inhibition of AHR expression causes a significant elevation of oxidative stress, γH2A.X histone phosphorylation, and E2F1-dependent apoptosis, which can be blocked by small interfering RNA-mediated knockdown of E2F1 expression. In contrast, ligand-dependent AHR activation protects these cells from etoposide-induced cell death. In cells expressing both proteins, AHR and E2F1 interact independently of the retinoblastoma protein (RB), because AHR and E2F1 coimmunoprecipitate from extracts of RB-negative cells. Additionally, chromatin immunoprecipitation assays indicate that AHR and E2F1 bind to the Apaf1 promoter at a region containing a consensus E2F1 binding site but no AHR binding sites. AHR activation represses Apaf1 and TAp73 mRNA induction by a constitutively active CHK2 expression vector. Furthermore, AHR overexpression blocks the transcriptional induction of Apaf1 and p73 and the accumulation of sub-G0/G1 cells resulting from ectopic overexpression of E2F1. These results point to a proproliferative, antiapoptotic function of the Ah receptor that likely plays a role in tumor progression. PMID:18524851

he pure rotational spectra of the n = 5, 6, 7, and 8 members of the 1-fluoroalkane family have been recorded between 7 GHz and 14 GHz using chirped pulse Fourier transform microwave spectroscopy. The spectra have been analyzed and results will be presented and compared with previous work on the n= 2, 3, and 4 members. The lowest energy conformer for all family members has the common feature that the fluorine is in a gauche position relative to the alkyl tail for which all other heavy atom dihedral angles, where appropriate, are 180 degrees. For the n = 3 and higher family members the second lowest energy conformer has all heavy atom dihedral angles equal to 180 degrees. For each family member transitions carried by both low energy conformers were observed in the collected rotational spectra. Quantum chemical calculations were performed and trends in the energy separations between these two common conformers will be presented as a function of chain length. Furthermore, longer chain lengths have been examined using only quantum chemical calculations and results will be presented. M. Hayashi, M. Fujitake, T. Inagusa, S.

Thirty-three families (71 subjects) were screened for the presence of Candida albicans in mouthwash or stool specimens; 12 families (28 subjects) were culture-positive for this yeast. An enrichment procedure provided a twofold increase in the recovery of C. albicans from mouthwash specimens. Nine of the twelve culture-positive families had two positive members each, two families had three positive members each, and one family had four positive members. Genetic profiles were obtained by three methods: pulsed-field gel electrophoresis; restriction endonuclease analysis, and random amplification of polymorphic DNA analysis. DNA fingerprinting of C. albicans isolated from one body site three consecutive times revealed that each of the 12 families carried a distinct genotype. No two families shared the same strain, and two or more members of a family commonly shared the same strain. Intrafamily genotypic identity (i.e., each member within the family harbored the same strain) was demonstrated in six families. Genotypes of isolates from husband and wife differed from one another in five families. All three methods were satisfactory in determining genotypes; however, we concluded that restriction endonuclease analysis provided adequate resolving power.

Arabidopsis thaliana BTB/ POZ-MATH proteins interact with members of the ERF/AP2 transcription factor family.

2009-11-01

In Arabidopsis thaliana, the BTB/POZ-MATH (BPM) proteins comprise a small family of six members. They have been described previously to use their broad complex, tram track, bric-a-brac/POX virus and zinc finger (BTB/POZ) domain to assemble with CUL3a and CUL3b and potentially to serve as substrate adaptors to cullin-based E3-ligases in plants. In this article, we show that BPMs can also assemble with members of the ethylene response factor/Apetala2 transcription factor family, and that this is mediated by their meprin and TRAF (tumor necrosis factor receptor-associated factor) homology (MATH) domain. In addition, we provide a detailed description of BPM gene expression patterns in different tissues and on abiotic stress treatments, as well as their subcellular localization. This work connects, for the first time, BPM proteins with ethylene response factor/Apetala2 family members, which is likely to represent a novel regulatory mechanism of transcriptional control.

EBP1 is a novel E2F target gene regulated by transforming growth factor-β.

PubMed

2010-11-10

Regulation of gene expression requires transcription factor binding to specific DNA elements, and a large body of work has focused on the identification of such sequences. However, it is becoming increasingly clear that eukaryotic transcription factors can exhibit widespread, nonfunctional binding to genomic DNA sites. Conversely, some of these proteins, such as E2F, can also modulate gene expression by binding to non-consensus elements. E2F comprises a family of transcription factors that play key roles in a wide variety of cellular functions, including survival, differentiation, activation during tissue regeneration, metabolism, and proliferation. E2F factors bind to the Erb3-binding protein 1 (EBP1) promoter in live cells. We now show that E2F binding to the EBP1 promoter occurs through two tandem DNA elements that do not conform to typical consensus E2F motifs. Exogenously expressed E2F1 activates EBP1 reporters lacking one, but not both sites, suggesting a degree of redundancy under certain conditions. E2F1 increases the levels of endogenous EBP1 mRNA in breast carcinoma and other transformed cell lines. In contrast, in non-transformed primary epidermal keratinocytes, E2F, together with the retinoblastoma family of proteins, appears to be involved in decreasing EBP1 mRNA abundance in response to growth inhibition by transforming growth factor-β1. Thus, E2F is likely a central coordinator of multiple responses that culminate in regulation of EBP1 gene expression, and which may vary depending on cell type and context.

The present study aimed to investigate the stress and coping strategies of Hong Kong Chinese families during a critical illness and to examine the relationships between stress and coping. Admissions to intensive care unit are usually an unanticipated event, which imposes stress on the family. Family's wellness is one of the significant factors affecting patient's well-beings. Much work has been conducted in Western societies. Stress and coping in Chinese families of critically ill patients have rarely been discussed. Structured face-to-face interviews were conducted, using the Impact of Events Scale and the Family Crisis Oriented Personal Evaluation Scales. A convenience sample of 133 participants was recruited from a regional hospital in Hong Kong. Many were patients' children with age between 30 and 49. A total of 39.1% (n = 52) of the participants were males and 60.9% (n = 81) were females. The participants experienced high level of stress (mean = 25.1, SD = 8.3). Higher level of stress were experienced by female (t = -4.6; d.f. = 1, 131; P = 0.00), those with lower educational attainment (F = 3.0; d.f. = 2, 130; P = 0.05) and those whose relatives were admitted to the intensive care unit unexpectedly (t = -2.2; d.f. = 1; P = 0.03). Patients' length of stay in the unit was significantly correlated with levels of stress (r = 0.5, P < 0.00). Level of stress had significant correlation with coping strategies utilization (r = 0.5, P < 0.00). Reframing strategies were frequently used whereas the passive appraisal strategies were least used. Family members used positive-coping strategies, which concurred with the Chinese stress-coping pattern 'fatalistic voluntarism'. This study contributes to the understanding of Hong Kong Chinese families' stress and coping during a critical illness. Comprehensive assessments of family members' psychosocial needs are important to plan appropriate interventions to alleviate their stress and strengthen their coping skills. The

E2fl1 is a meiosis-specific transcription factor in the protist Tetrahymena thermophila

2017-01-01

ABSTRACT Members of the E2F family of transcription factors have been reported to regulate the expression of genes involved in cell cycle control, DNA replication, and DNA repair in multicellular eukaryotes. Here, E2FL1, a meiosis-specific E2F transcription factor gene, was identified in the model ciliate Tetrahymena thermophila. Loss of this gene resulted in meiotic arrest prior to anaphase I. The cytological experiments revealed that the meiotic homologous pairing was not affected in the absence of E2FL1, but the paired homologous chromosomes did not separate and assumed a peculiar tandem arrangement. This is the first time that an E2F family member has been shown to regulate meiotic events. Moreover, BrdU incorporation showed that DSB processing during meiosis was abnormal upon the deletion of E2FL1. Transcriptome sequencing analysis revealed that E2FL1 knockout decreased the expression of genes involved in DNA replication and DNA repair in T. thermophila, suggesting that the function of E2F is highly conserved in eukaryotes. In addition, E2FL1 deletion inhibited the expression of related homologous chromosome segregation genes in T. thermophila. The result may explain the meiotic arrest phenotype at anaphase I. Finally, by searching for E2F DNA-binding motifs in the entire T. thermophila genome, we identified 714 genes containing at least one E2F DNA-binding motif; of these, 235 downregulated represent putative E2FL1 target genes.

E2F transcription factors are central to epidermal morphogenesis and regeneration after injury. The precise nature of E2F target genes involved in epidermal formation and repair has yet to be determined. Identification of these genes is essential to understand how E2F proteins regulate fundamental aspects of epidermal homeostasis and transformation. We have conducted a genome-wide screen using CpG island microarray analysis to identify novel promoters bound by E2F3 and E2F5 in human keratinocytes. We further characterized several of these genes, and determined that multiple E2F and retinoblastoma (pRb) family proteins associate with them in exponentially proliferating cells. We also assessed the effect on E2F and pRb binding to those genes in response to differentiation induced by bone morphogenetic protein-6 (BMP-6), or to activation of repair mechanisms induced by transforming growth factor-beta (TGF-beta). These studies demonstrate promoter- and cytokine-specific changes in binding profiles of E2F and/or pRb family proteins. For example, E2F1, 3, 4 and p107 were recruited to the N-myc promoter in cells treated with BMP-6, whereas E2F1, 3, 4, 5, p107 and p130 were bound to this promoter in the presence of TGF-beta. Functionally, these different interactions resulted in transcriptional repression by BMP-6 and TGF-beta of the N-myc gene, via mechanisms that involved E2F binding to the promoter and association with pRb-family proteins. Thus, multiple combinations of E2F and pRb family proteins may associate with and transcriptionally regulate a given target promoter in response to differentiation and injury-repair stimuli in epidermal keratinocytes.

Purpose To identify genes underlying autosomal recessive retinitis pigmentosa (ARRP) by homozygosity mapping. Methods Families with ARRP were recruited after complete ophthalmic evaluation of all members and diagnosis of RP by predefined criteria. Genomic DNA from affected members of 26 families was genotyped on Illumina single nucleotide polymorphism (SNP) 6.0 K arrays with standard procedures. Genotypes were evaluated for homozygous regions that were common and concordant between affected members of each family. The genes mapping to homozygous intervals within these families were screened for pathogenic changes with PCR amplification and sequencing of coding regions. Cosegegration of sequence changes with disease was determined within each pedigree, and each variation was tested for presence in 100 unrelated normal controls. Results A genome-wide scan for homozygosity showed homozygous regions harboring the tubby like protein 1 gene (TULP1; chromosome 6) in one family, the nuclear receptor subfamily 2, group E, member 3 gene (NR2E3; chromosome 15) in three families, and the membrane frizzled-related protein gene (MFRP; chromosome 11) in one family. Screening of the three genes in the respective families revealed homozygous disease-causing mutations in three families. These included a missense mutation in TULP1, a deletion-cum-insertion in NR2E3, and a single base deletion in MFRP. Patients from all three families had a rod-cone type of dystrophy with night blindness initially. The NR2E3 and MFRP genes were associated with fundus features atypical of RP. Conclusions This study shows involvement of the TULP1, NR2E3, and MFRP genes in ARRP in Indian cases. Genome-wide screening with SNP arrays followed by a prioritized candidate gene evaluation is useful in identifying genes in these patients. PMID:22605927

Familial Papillary Thyroid Carcinoma (PTC) has been described as a hereditary predisposition cancer syndrome associated with mutations in candidate genes including HABP2. Two of 20 probands from families with history of PTC and breast carcinoma (BC) were evaluated by whole exome sequencing (WES) revealing HABP2 p.G534E. Sanger sequencing was used to confirm the involvement of this variant in three families (F1: 7 relatives; F2: 3 and F3: 3). The proband and his sister (with no malignant tumor so far) from F1 were homozygous for the variant whereas one relative with PTC from F2 was negative for the variant. Although the proband of the F3 with PTC was HABP2 wild type, three relatives presented the variant. Five of 170 healthy Brazilian individuals with no family history of BC or PTC and three of 50 sporadic PTC presented the p.G534E. These findings suggested no association of this variant with our familial PTC cases. Genes potentially associated with deregulation of the extracellular matrix organization pathway (CTSB, TNXB, COL4A3, COL16A1, COL24A1, COL5A2, NID1, LOXL2, MMP11, TRIM24 and MUSK) and DNA repair function (NBN and MSH2) were detected by WES, suggesting that other cancer-associated genes have pathogenic effects in the risk of familial PTC development.

The cellular basis of liver regeneration has been intensely investigated for many years. However, the mechanisms initiating hepatocyte "plasticity" and priming for proliferation are not yet fully clear. We investigated alterations in gene expression patterns during the first 72 hours of C57BL/6N mouse hepatocyte culture on collagen monolayers (CM), which display a high basal frequency of proliferation in the absence of cytokines. Although many metabolic genes were down-regulated, genes related to mitogen-activated protein kinase (MAPK) signaling and cell cycle were up-regulated. The latter genes showed an overrepresentation of transcription factor binding sites (TFBS) for ETF (TEA domain family member 2), E2F1 (E2F transcription factor 1), and SP-1 (Sp1 transcription factor) (P < 0.001), all depending on MAPK signaling. Time-dependent increase of ERK1/2 phosphorylation occurred during the first 48 hours (and beyond) in the absence of cytokines, accompanied by an enhanced bromodeoxyuridine labeling index of 20%. The MEK inhibitor PD98059 blunted these effects indicating MAPK signaling as major trigger for this cytokine-independent proliferative response. In line with these in vitro findings, liver tissue of mice challenged with CCl(4) displayed hepatocytes with intense p-ERK1/2 staining and nuclear SP-1 and E2F1 expression. Furthermore, differentially expressed genes in mice after partial hepatectomy contained overrepresented TFBS for ETF, E2F1, and SP-1 and displayed increased expression of E2F1. Cultivation of murine hepatocytes on CM primes cells for proliferation through cytokine-independent activation of MAPK signaling. The transcription factors ETF, E2F1, and SP-1 seem to play a pronounced role in mediating proliferation-dependent differential gene expression. Similar events, but on a shorter time-scale, occur very early after liver damage in vivo. Copyright © 2010 American Association for the Study of Liver Diseases.

Studies have shown an association between intensive care unit environments and symptoms of psychological distress in family members of critically ill patients. To investigate levels of cardiac anxiety in family members of intensive care unit patients. From March 2012 to July 2013, on the third day after the patient's admission, 223 family members of 147 patients completed the Cardiac Anxiety Questionnaire. A total score was calculated from 3 subscales: fear and worry about heart sensations, avoidance of activities reproducing cardiac symptoms, and heart-focused attention and monitoring of cardiac activity. Among the family members, 142 were women (63.7%) and 81 (36.3%) were men, 150 (67.3%) were married, and 37 (16.6%) were unemployed. Their mean score for overall cardiac anxiety was 1.11 (SD, 0.64), significantly higher (P < .001) than for the general Greek population. Although all 3 subscales scores were significantly higher than for the general population, the highest score was recorded for the avoidance subscale (mean, 1.77; SD, 0.68). The relationship to the patient had a significant effect on heart-focused attention (F5 = 3.51; P = .03). The mean score for patients' siblings (2.0; SD, 0.01) differed significantly (P = .02) from the mean for other family member groups. Older adults (P = .02) and married participants (P = .05) reported higher levels of fear and worry related to cardiac stimuli, and women further reported higher levels of cardioprotective avoidance behavior (P = .02). A noticeable number of family members of critical care patients had moderate to severe cardiac anxiety during the hospitalization of their relatives. ©2016 American Association of Critical-Care Nurses.

Interventions to improve communication among family members may facilitate information flow about familial risk and preventive health behaviors. This is a secondary analysis of the effects of an interactive website intervention aimed at increasing communication frequency and agreement about health risk among melanoma families. Participants were family units, consisting of one family member with melanoma identified from a previous research study (the Case) and an additional first degree relative and a parent of a child 0-17. Family triads were randomized to receive access to the website intervention or to serve as control families. Family communication frequency and agreement about melanoma prevention behaviors and beliefs were measured at baseline and again at 1 year post randomization. Intervention participants of all three types significantly increased the frequency of communication to their first degree relatives (Parents, siblings, children; range = 14-18 percentage points; all p < .05). At baseline, approximately two-thirds of all three family members talked with at least some member of the family about cancer risk. Agreement between Cases and First Degree Relatives and between Cases and Parents increased from pre to post intervention in the intervention participants compared to the control participants (p < .05). These findings provide support for interventions to improve family communication about cancer risk.

An interval on barley (Hordeum vulgare L.) chromosome 7 accounting for significant quantitative trait locus effects for winter hardiness were detected in a winter (Dicktoo) x spring (Morex) barley population (P.M. Hayes, T. Blake, T.H.H. Chen, S. Tragoonrung, F. Chen, A. Pan, and B. Liu [1993] Genome 36: 66-71). Two members of the barley dehydrin gene family, Dhn1 and Dhn2, were located within the region defining the winter hardiness quantitative trait locus effect (A. Pan, P.M. Hayes, F. Chen, T. Blake, T.H.H. Chen, T.T.S. Wright, I. Karsai, Z. Bedo [1994] Theor Appl Genet 89: 900-910). To investigate the possible role of Dhn1 and Dhn2 in winter hardiness, we examined the expression pattern of six barley dehydrin gene family members in shoot tissue in response to cold temperature. Incubation of 3-week-old barley plants at 2[deg]C resulted in a rapid induction of a single 86-kD polypeptide that was recognized by an antiserum against a peptide conserved in the dehydrin gene family. Northern blot analysis confirmed the induction of an mRNA corresponding to Dhn5. The expression patterns of cold-induced dehydrins in shoot tissue for Dicktoo and Morex were identical under the conditions studied, in spite of the known phenotypic differences in their winter hardiness. These results, together with the allelic structure of selected high- and low-survival lines, suggest that the Dicktoo alleles at the Dhn1 and Dhn2 may not be the primary determinants of winter hardiness in barley.

The yabJ gene in Bacillus subtilis is required for adenine-mediated repression of purine biosynthetic genes in vivo and codes for an acid-soluble, 14-kDa protein. The molecular mechanism of YabJ is unknown. YabJ is a member of a large, widely distributed family of proteins of unknown biochemical function. The 1.7-Å crystal structure of YabJ reveals a trimeric organization with extensive buried hydrophobic surface and an internal water-filled cavity. The most important finding in the structure is a deep, narrow cleft between subunits lined with nine side chains that are invariant among the 25 most similar homologs. This conserved site is proposed to be a binding or catalytic site for a ligand or substrate that is common to YabJ and other members of the YER057c/YjgF/UK114 family of proteins. PMID:10557275

Functional synergy between DP-1 and E2F-1 in the cell cycle-regulating transcription factor DRTF1/E2F.

It is widely believed that the cellular transcription factor DRTF1/E2F integrates cell cycle events with the transcription apparatus because during cell cycle progression in mammalian cells it interacts with molecules that are important regulators of cellular proliferation, such as the retinoblastoma tumour suppressor gene product (pRb), p107, cyclins and cyclin-dependent kinases. Thus, pRb, which negatively regulates early cell cycle progression and is frequently mutated in tumour cells, and the Rb-related protein p107, bind to and repress the transcriptional activity of DRTF1/E2F. Viral oncoproteins, such as adenovirus E1a and SV40 large T antigen, overcome such repression by sequestering pRb and p107 and in so doing are likely to activate genes regulated by DRTF1/E2F, such as cdc2, c-myc and DHFR. Two sequence-specific DNA binding proteins, E2F-1 and DP-1, which bind to the E2F site, contain a small region of similarity. The functional relationship between them has, however, been unclear. We report here that DP-1 and E2F-1 exist in a DNA binding complex in vivo and that they bind efficiently and preferentially as a heterodimer to the E2F site. Moreover, studies in yeast and Drosophila cells indicate that DP-1 and E2F-1 interact synergistically in E2F site-dependent transcriptional activation. Images PMID:8223441

miR-30 Family Members Negatively Regulate Osteoblast Differentiation*

miRNAs are endogenously expressed 18- to 25-nucleotide RNAs that regulate gene expression through translational repression by binding to a target mRNA. Recently, it has been indicated that miRNAs are closely related to osteogenesis. Our previous data suggested that miR-30 family members might be important regulators during the biomineralization process. However, whether and how they modulate osteogenic differentiation have not been explored. In this study, we demonstrated that miR-30 family members negatively regulate BMP-2-induced osteoblast differentiation by targeting Smad1 and Runx2. Evidentially, overexpression of miR-30 family members led to a decrease of alkaline phosphatase activity, whereas knockdown of them increased the activity. Then bioinformatic analysis identified potential target sites of the miR-30 family located in the 3′ untranslated regions of Smad1 and Runx2. Western blot analysis and quantitative RT-PCR assays demonstrated that miR-30 family members inhibit Smad1 gene expression on the basis of repressing its translation. Furthermore, dual-luciferase reporter assays confirmed that Smad1 is a direct target of miR-30 family members. Rescue experiments that overexpress Smad1 and Runx2 significantly eliminated the inhibitory effect of miR-30 on osteogenic differentiation and provided strong evidence that miR-30 mediates the inhibition of osteogenesis by targeting Smad1 and Runx2. Also, the inhibitory effects of the miR-30 family were validated in mouse bone marrow mesenchymal stem cells. Therefore, our study uncovered that miR-30 family members are key negative regulators of BMP-2-mediated osteogenic differentiation. PMID:22253433

THE ROLE OF THE RETINOBLASTOMA/E2F1 TUMOR SUPPRESSOR PATHWAY IN THE LESION RECOGNITION STEP OF NUCLEOTIDE EXCISION REPAIR

2009-01-01

The retinoblastoma Rb/E2F tumor suppressor pathway plays a major role in the regulation of mammalian cell cycle progression. The pRb protein, along with closely related proteins p107 and p130, exerts its anti-proliferative effects by binding to the E2F family of transcription factors known to regulate essential genes throughout the cell cycle. We sought to investigate the role of the Rb/E2F1 pathway in the lesion recognition step of nucleotide excision repair (NER) in mouse embryonic fibroblasts (MEFs). Rb−/−;p107−/−;p130−/− MEFs repaired both cyclobutane pyrimidine dimers (CPD) and 6-4 photoproducts (6-4PPs) at higher efficiency than did wildtype cells following UV-C irradiation. The expression of damaged DNA binding gene DDB2 involved in the DNA lesion recognition step was elevated in the Rb family-deficient MEFs. To determine if the enhanced DNA repair in the absence of the Rb gene family is due to the derepression of E2F1, we assayed the ability of E2F1-deficient cells to repair damaged DNA and demonstrated that E2F1−/− MEFs are impaired for the removal of both CPDs and 6-4PPs. Furthermore, wildtype cells induced a higher expression of DDB2 and xeroderma pigmentosum gene XPC transcript levels than did E2F1−/− cells following UV-C irradiation. Using an E2F SiteScan algorithm, we uncovered a putative E2F-responsive element in the XPC promoter upstream of the transcription start site. We showed with chromatin immunoprecipitation assays the binding of E2F1 to the XPC promoter in a UV-dependent manner, suggesting that E2F1 is a transcriptional regulator of XPC. Our study identifies a novel E2F1 gene target and further supports the growing body of evidence that the Rb/E2F1 tumor suppressor pathway is involved in the regulation of the DNA lesion recognition step of nucleotide excision repair.

Genetically engineered mouse models for functional studies of SKP1-CUL1-F-box-protein (SCF) E3 ubiquitin ligases.

PubMed

Zhou, Weihua; Wei, Wenyi; Sun, Yi

2013-05-01

The SCF (SKP1 (S-phase-kinase-associated protein 1), Cullin-1, F-box protein) E3 ubiquitin ligases, the founding member of Cullin-RING ligases (CRLs), are the largest family of E3 ubiquitin ligases in mammals. Each individual SCF E3 ligase consists of one adaptor protein SKP1, one scaffold protein cullin-1 (the first family member of the eight cullins), one F-box protein out of 69 family members, and one out of two RING (Really Interesting New Gene) family proteins RBX1/ROC1 or RBX2/ROC2/SAG/RNF7. Various combinations of these four components construct a large number of SCF E3s that promote the degradation of many key regulatory proteins in cell-context, temporally, and spatially dependent manners, thus controlling precisely numerous important cellular processes, including cell cycle progression, apoptosis, gene transcription, signal transduction, DNA replication, maintenance of genome integrity, and tumorigenesis. To understand how the SCF E3 ligases regulate these cellular processes and embryonic development under in vivo physiological conditions, a number of mouse models with transgenic (Tg) expression or targeted deletion of components of SCF have been established and characterized. In this review, we will provide a brief introduction to the ubiquitin-proteasome system (UPS) and the SCF E3 ubiquitin ligases, followed by a comprehensive overview on the existing Tg and knockout (KO) mouse models of the SCF E3s, and discuss the role of each component in mouse embryogenesis, cell proliferation, apoptosis, carcinogenesis, as well as other pathogenic processes associated with human diseases. We will end with a brief discussion on the future directions of this research area and the potential applications of the knowledge gained to more effective therapeutic interventions of human diseases.

Constraining the Formation of Haumea using the Distribution of Haumea Family Members

NASA Astrophysics Data System (ADS)

Proudfoot, Benjamin; Ragozzine, Darin

2017-10-01

Collisions are a central component of the formation and evolution of the outer Solar System. The dwarf planet Haumea and its compact collisional family provide a unique empirical view into how collisions take place in the outer Solar System. Although there have been many publications dedicated to understanding Haumea, there have yet to be any fully self-consistent models for the formation of Haumea and its family. In particular, it is a challenge to explain why the relative velocities of family members ("Delta v") is several times smaller than would be expected. Using a much larger number of Haumea family members (see Maggard & Ragozzine, this meeting), we focus on finding the best empirical model for the three-dimensional "Delta v" distribution of Haumea family members. We consider an isotropic ejection from Haumea, a planar ejection resulting from a graze and merge type impact (e.g., Leinhardt et al. 2010), and an isotropic ejection from a satellite of Haumea (e.g., Schlichting & Sari 2009). These models create a large simulated family with tunable parameters that result in a unique distribution in a-e-i-Deltav-H space. Preliminary results indicated that the graze-and-merge impact is inconsistent with the observed distribution of family members (Ragozzine & Proudfoot, DDA 2017). We explore this more rigorously here by including tunable parameters, a Bayesian methodology, and the influence of background interlopers.

Crystal structure and potential physiological role of zebra fish thioesterase superfamily member 2 (fTHEM2)

Yu, Shanshan; Li, Han; Gao, Feng

2015-08-07

Thioesterase superfamily member 2 (THEM2) is an essential protein for mammalian cell proliferation. It belongs to the hotdog-fold thioesterase superfamily and catalyzes hydrolysis of thioester bonds of acyl-CoA in vitro, while its in vivo function remains unrevealed. In this study, Zebra fish was selected as a model organism to facilitate the investigations on THEM2. First, we solved the crystal structure of recombinant fTHEM2 at the resolution of 1.80 Å, which displayed a similar scaffolding as hTHEM2. Second, functional studies demonstrated that fTHEM2 is capable of hydrolyzing palmitoyl-CoA in vitro. In addition, injection of morpholino against fTHEM2 at one-cell stage resulted in distorted early embryomore » development, including delayed cell division, retarded development and increased death rate. The above findings validated our hypothesis that fTHEM2 could serve as an ideal surrogate for studying the physiological functions of THEM2. - Highlights: • The crystal structure of recombinant fTHEM2 is presented. • fTHEM2 is capable of hydrolyzing palmitoyl-CoA. • The influence of fTHEM2 on early embryo development is demonstrated.« less

Unrecognized pediatric and adult family members of children with acute brucellosis.

PubMed

Çiftdoğan, Dilek Yılmaz; Aslan, Selda

Brucellosis is an infectious, contagious and zoonotic disease that occurs worldwide. The family members of an index case of brucellosis may be especially susceptible, due to sharing the same source of infection and similar risk factors for brucellosis. In this study, we propose to screen pediatric and adult family members of brucellosis index cases for detecting additional unrecognized infected family members. 114 family members of 41 pediatric patients with brucellosis were evaluated. All family members completed a brief questionnaire and were tested by a standard tube agglutination test (STA). The majority of family members (n=96, 84.2%) were children. Among the 114 family members, 42 (36.8%) were seropositive, and 15 (35.7%) were symptomatic. The majority of the symptomatic seropositive family members (n=12, 80%) had STA titers (≥1:640) higher than asymptomatic seropositive family members (n=9, 33%; p=0.004). The routine screening of both pediatric and adult family members of index cases is a priority in endemic areas. Using this screening approach, unrecognized family members who are seropositive for brucellosis will be identified earlier and be able to receive prompt treatment.

Using the Family Assessment Device (FAD; Epstein, Baldwin, & Bishop, 1983) and incorporating the perspectives of adolescent, mother, and father, this study examined each family member's “unique perspective” or non-shared, idiosyncratic view of the family. To do so we used a modified multitrait-multimethod confirmatory factor analysis that (1) isolated for each family member's six reports of family dysfunction the non-shared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by one or more family members and (2) extracted common variance across each family member's set of non-shared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. Additionally, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these “unique perspectives” reflect about the family are discussed. PMID:22545933

TFDP3 has been previously identified as an inhibitor of E2F molecules. It has been shown to suppress E2F1-induced apoptosis dependent P53 and to play a potential role in carcinogenesis. However, whether it indeed helps cancer cells tolerate apoptosis stress in cancer tissues remains unknown. TFDP3 expression was assessed by RT-PCR, in situ hybridization and immunohistochemistry in normal human tissues, cancer tissues and prostate cancer tissues. The association between TFDP3 and E2F1 in prostate cancer development was analyzed in various stages. Apoptosis was evaluated with annexin-V and propidium iodide staining and flow-cytometry. The results show that, in 96 samples of normal human tissues, TFDP3 could be detected in the cerebrum, esophagus, stomach, small intestine, bronchus, breast, ovary, uterus, and skin, but seldom in the lung, muscles, prostate, and liver. In addition, TFDP3 was highly expressed in numerous cancer tissues, such as brain-keratinous, lung squamous cell carcinoma, testicular seminoma, cervical carcinoma, skin squamous cell carcinoma, gastric adenocarcinoma, liver cancer, and prostate cancer. Moreover, TFDP3 was positive in 23 (62.2%) of 37 prostate cancer samples regardless of stage. Furthermore, immunohistochemistry results show that TFDP3 was always expressed in coordination with E2F1 at equivalent expression levels in prostate cancer tissues, and was highly expressed particularly in samples of high stage. When E2F1 was extrogenously expressed in LNCap cells, TFDP3 could be induced, and the apoptosis induced by E2F1 was significantly decreased. It was demonstrated that TFDP3 was a broadly expressed protein corresponding to E2F1 in human tissues, and suggested that TFDP3 is involved in prostate cancer cell survival by suppressing apoptosis induced by E2F1.

The Massachusetts Department of Public Health Overdose Education and Naloxone Distribution Program provides overdose education and naloxone rescue kits to people at risk for overdose and bystanders, including family members. Using Massachusetts Department of Public Health data, the aims are to: (i) describe characteristics of family members who receive naloxone; (ii) identify where family members obtain naloxone; and (iii) describe characteristics of rescues by family members. We conducted a retrospective review using program enrollee information collected on a standardised form between 2008 and 2015. We calculated descriptive statistics, including demographics, current substance use, enrolment location, history of witnessed overdoses and rescue attempt characteristics. We conducted a stratified analysis comparing family members who used drugs with those who did not. Family members were 27% of total program enrollees (n = 10 883/40 801). Family members who reported substance use (n = 4679) were 35.6 years (mean), 50.6% female, 76.3% non-Hispanic white, 75.6% had witnessed an overdose, and they obtained naloxone most frequently at HIV prevention programs. Family members who did not report substance use (n = 6148) were 49.2 years (mean), 73.8% female, 87.9% non-Hispanic white, 35.3% had witnessed an overdose, and they obtained naloxone most frequently at community meetings. Family members were responsible for 20% (n = 860/4373) of the total rescue attempts. The Massachusetts experience demonstrates that family members can be active participants in responding to the overdose epidemic by rescuing family members and others. Targeted intervention strategies for families should be included in efforts to expand overdose education and naloxone in Massachusetts. © 2017 Australasian Professional Society on Alcohol and other Drugs.

Dignity Therapy is a novel therapeutic intervention designed to address psychosocial and existential distress among the terminally ill. This brief, individualized approach to end-of-life care invites patients to discuss issues that are most important to them and to articulate things they would most want remembered as death draws near. These discussions and recollections are recorded, transcribed, and edited into a generativity document, which are usually given to family or loved ones. While the marked benefits of Dignity Therapy on patients' psychosocial and existential distress have been reported elsewhere, this paper presents data on bereft family members' perspectives regarding the impact of dignity therapy on patients and themselves. Sixty family members of deceased terminally ill patients who previously took part in Dignity Therapy completed a questionnaire to elicit feedback about the impact of Dignity Therapy on both the dying patient and themselves. Ninety-five percent of participants reported that Dignity Therapy helped the patient; 78% reported that it heightened the patient's sense of dignity; 72% reported that it heightened the patient's sense of purpose; 65% reported that it helped the patient prepare for death; 65% reported that it was as important as any other aspect of the patient's care; and 43% reported that Dignity Therapy reduced the patient's suffering. Regarding family members, 78% reported that the generativity document helped them during their time of grief; 77% reported that the document would continue to be a source of comfort for their families and themselves; and 95% reported they would recommend Dignity Therapy to other patients of family members confronting a terminal illness. Family members endorse Dignity Therapy as a therapeutic intervention that moderates their bereavement experiences and lessens suffering and distress in terminally ill relatives.

Managing patients whose family members are physicians.

PubMed

Bramstedt, K A; Popovich, M

2012-01-01

The ethical complexities involving physicians who treat their own family members are well known and it is generally accepted that such practice should not occur. We present three anonymous cases in which patient family members who worked as physicians complicated the medical care of their hospitalized relatives. When a health care worker's family member becomes a hospital patient, the situation can be emotionally charged due to the medical insight the multiple parties have, as well as the desire of relatives to be protective of their family members. Clinician-relatives need to allow the medical team to assume the role of caretaker when their family members are hospitalized. Teams may need to employ limit setting in order to ensure fair and consistent care for all patients on the ward, and to prevent escalation of emotionally charged situations.

E2f1–3 Are Critical for Myeloid Development*

Hematopoietic development involves the coordinated activity of differentiation and cell cycle regulators. In current models of mammalian cell cycle control, E2f activators (E2f1, E2f2, and E2f3) are portrayed as the ultimate transcriptional effectors that commit cells to enter and progress through S phase. Using conditional gene knock-out strategies, we show that E2f1–3 are not required for the proliferation of early myeloid progenitors. Rather, these E2fs are critical for cell survival and proliferation at two distinct steps of myeloid development. First, E2f1–3 are required as transcriptional repressors for the survival of CD11b+ myeloid progenitors, and then they are required as activators for the proliferation of CD11b+ macrophages. In bone marrow macrophages, we show that E2f1–3 respond to CSF1-Myc mitogenic signals and serve to activate E2f target genes and promote their proliferation. Together, these findings expose dual functions for E2f1–3 at distinct stages of myeloid development in vivo, first as repressors in cell survival and then as activators in cell proliferation. In summary, this work places E2f1–3 in a specific signaling cascade that is critical for myeloid development in vivo. PMID:21115501

A central aspect of development and disease is the control of cell proliferation through regulation of the mitotic cycle. Cell cycle progression and directionality requires an appropriate balance of positive and negative regulators whose expression must fluctuate in a coordinated manner. p19INK4d, a member of the INK4 family of CDK inhibitors, has a unique feature that distinguishes it from the remaining INK4 and makes it a likely candidate for contributing to the directionality of the cell cycle. p19INK4d mRNA and protein levels accumulate periodically during the cell cycle under normal conditions, a feature reminiscent of cyclins. In this paper, we demonstrate that p19INK4d is transcriptionally regulated by E2F1 through two response elements present in the p19INK4d promoter. Ablation of this regulation reduced p19 levels and restricted its expression during the cell cycle, reflecting the contribution of a transcriptional effect of E2F1 on p19 periodicity. The induction of p19INK4d is delayed during the cell cycle compared to that of cyclin E, temporally separating the induction of these proliferative and antiproliferative target genes. Specific inhibition of the E2F1-p19INK4d pathway using triplex-forming oligonucleotides that block E2F1 binding on p19 promoter, stimulated cell proliferation and increased the fraction of cells in S phase. The results described here support a model of normal cell cycle progression in which, following phosphorylation of pRb, free E2F induces cyclin E, among other target genes. Once cyclinE/CDK2 takes over as the cell cycle driving kinase activity, the induction of p19 mediated by E2F1 leads to inhibition of the CDK4,6-containing complexes, bringing the G1 phase to an end. This regulatory mechanism constitutes a new negative feedback loop that terminates the G1 phase proliferative signal, contributing to the proper coordination of the cell cycle and provides an additional mechanism to limit E2F activity.

Research has documented numerous benefits and challenges associated with receipt of hospice care in nursing homes; however, study of this partnership from the perspective of residents' family members has been limited. The purpose of this qualitative investigation was to explore family members' experience with hospice services received in the nursing home setting. Researchers conducted a secondary data analysis of 175 family member interviews using a thematic analytic approach. Findings highlighted the critical role of communication in supporting residents and their family members. Care coordination, support and oversight, and role confusion also impacted family members' experience of hospice care in the nursing home. Efforts directed at enhancing communication and more clearly articulating the roles of members of the health care team are indicated. © The Author(s) 2014.

Many members of the Themis family show evidence of hydration in the form of oxidized iron in phyllosilicates (Florczak, M. et al. [1999]. Astron. Astrophys. Suppl. Ser. 134, 463-471), and OH-bearing minerals (Takir, D., Emery, J.P. [2012]. Icarus 219, 641-654). The largest member, (24) Themis, has H2O ice covering its surface (Campins, H. et al. [2010]. Nature 464, 1320-1321; Rivkin, A.S., Emery, J.P. [2010]. Nature 464, 1322-1323). We have investigated the second largest Themis-family asteroid, (90) Antiope, which Castillo-Rogez and Schmidt (Castillo-Rogez, J.C., Schmidt, B.E. [2010]. Geophys. Res. Lett. 37, L10202) predict to have a composition that includes water ice and organics. We obtained 2-4-μm spectroscopy of (90) Antiope in 2006 and 2008, and we find an absorption in the 3-μm region clearly present in our 2008 spectrum and likely in our 2006 spectrum. Both spectra have rounded, bowl-shaped absorptions consistent with those ascribed to water ice as in the spectrum of Asteroid (24) Themis. We also present and compare Spitzer 8-12-μm mid-infrared spectra of (24) Themis and (90) Antiope. We find that (90) Antiope is lacking a "fairy castle" dusty surface, which is in contrast to (24) Themis, other Themis family members (Licandro, J. et al. [2012]. Astron. Astrophys. 537, A73), and Jupiter Trojans (e.g. Emery, J.P., Cruikshank, D.P., Van Cleve, J. [2006]. Icarus 182, 496-512). We conclude that the surface structure of (90) Antiope is most similar to Cybele Asteroid (121) Hermione (Hargrove, K.D. et al. [2012]. Icarus 221, 453-455).

Family presence during resuscitation (FPDR) has advantages for the patients' family member to be present at the bedside. However, FPDR is not regularly practiced by nurses, especially in low to middle income countries. The purpose of this study was to determine Iranian nurses' and family members' attitudes towards FPDR. In a descriptive study, data was collected from the random sample of 178 nurses and 136 family members in four hospitals located in Iran. A 27-item questionnaire was used to collect data on attitudes towards FPDR, and descriptive and correlational analyses were conducted. Of family members, particularly the women, 57.2% (n=78) felt it is their right to experience FPDR and that it has many advantages for the family; including the ability to see that everything was done and worry less. However, 62.5% (n=111) of the nurses disagreed with an adult implementation of FPDR. Nurses perceived FPDR to have many disadvantages. Family members becoming distressed and interfering with the patient which may prolong the resuscitation effort. Nurses with prior education on FPDR were more willing to implement it. FPDR was desired by the majority of family members. To meet their needs, it is important to improve Iranian nurses' views about the advantages of the implementation of FPDR. Education on FPDR is recommended to improve Iranian nurses' views about the advantages of the implementation of FPDR. Copyright © 2017 Elsevier Ltd. All rights reserved.

Mixed methods phenomenological research approach. Semi-structured interviews and health-related quality of life questionnaires were conducted with 15 family members of individuals with ABI (early group: 1-12 months post-injury, n = 6; later group: >1 year post-injury, n = 9). Two main themes were identified: Different for everyone: how driving disruption affects families, and Making it harder: context of driving disruption. The challenges of driving disruption were reported more frequently and with a more intense focus by family members who were caring for their relative for more than 1 year post-injury. This group also reported higher caregiver strain and poorer health-related quality of life. Reduced satisfaction with life, poor mental health and affected family functioning were reported by both groups. Driving disruption impacts on family members and has long-lasting consequences. It is important for clinicians to work with family members to manage these challenges even years after ABI and consider individual contextual factors.

Polyploidization is observed in all mammalian species and is a characteristic feature of hepatocytes, but its molecular mechanism and biological significance are unknown. Hepatocyte polyploidization in rodents occurs through incomplete cytokinesis, starts after weaning and increases with age. Here, we show in mice that atypical E2F8 is induced after weaning and required for hepatocyte binucleation and polyploidization. A deficiency in E2f8 led to an increase in the expression level of E2F target genes promoting cytokinesis and thereby preventing polyploidization. In contrast, loss of E2f1 enhanced polyploidization and suppressed the polyploidization defect of hepatocytes deficient for atypical E2Fs. In addition, E2F8 and E2F1 were found on the same subset of target promoters. Contrary to the long-standing hypothesis that polyploidization indicates terminal differentiation and senescence, we show that prevention of polyploidization through inactivation of atypical E2Fs has, surprisingly, no impact on liver differentiation, zonation, metabolism and regeneration. Together, these results identify E2F8 as a repressor and E2F1 as an activator of a transcriptional network controlling polyploidization in mammalian cells.

Pseudouridine synthases catalyze the isomerization of uridine to pseudouridine ({psi}) in rRNA and tRNA. The pseudouridine synthase RluF from Escherichia coli (E.C. 4.2.1.70) modifies U2604 in 23S rRNA, and belongs to a large family of pseudouridine synthases present in all kingdoms of life. Here we report the domain architecture and crystal structure of the catalytic domain of E. coli RluF at 2.6 Angstroms resolution. Limited proteolysis, mass spectrometry and N-terminal sequencing indicate that RluF has a distinct domain architecture, with the catalytic domain flanked at the N and C termini by additional domains connected to it by flexible linkers. Themore » structure of the catalytic domain of RluF is similar to those of RsuA and TruB. RluF is a member of the RsuA sequence family of {psi}-synthases, along with RluB and RluE.

Salmond, Susan W

2011-02-01

The aim of this study was to explore the experience of being a nurse family member of a relative hospitalised for a critical illness. This paper will describe how nurse family members viewed the challenges of the illness experience and the strategies used to manage the challenges and cope with their loved one's critical illness. A qualitative approach using open-ended, focused exploratory interviews was used. Theoretical sampling was used to obtain a total of 22 participants. The knowledge base of the nurse filtered the experience for the nurse family member and their nurse role identity infused each component of the experience. Nurse family members identified their primary role as maintaining guard to protect the patient and family. To accomplish this, six challenges were identified: masking heightened emotional turmoil; assuming the in-charge role; assessing and monitoring; seeking information and meaning; advocating; and, "letting go to assume family and self roles". Strategies to facilitate meeting these challenges are described. In order to provide family-centered care, the critical care nurse must recognise the unique needs of the "nurse family member." By empathising with the emotional experience, allowing the "in-charge" nurse family member to be part of the team, facilitating ongoing observation and monitoring by the nurse family member, seeking out and clarifying information for the nurse family member and partnering to advocate for the patient, the critical care nurse builds a relationship of trust that allows the nurse family member to assume their family role.

PubMed

2008-08-12

This final rule implements sections 704 and 705 of the Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005. These provisions apply to eligible family members who become eligible for TRICARE as a result of their Reserve Component (RC) sponsor (including those with delayed effective date orders up to 90 days) being called or ordered to active duty for more than 30 days in support of a federal/contingency operation and choose to participate in TRICARE Standard or Extra, rather than enroll in TRICARE Prime. The first provision gives the Secretary the authority to waive the annual TRICARE Standard (or Extra) deductible, which is set by law (10 U.S.C. 1079(b)) at $150 per individual and $300 per family ($50/$100 for families of members in pay grades E-4 and below). The second provision gives the Secretary the authority to increase TRICARE payments up to 115 percent of the TRICARE maximum allowable charge, less the applicable patient cost share if not previously waived under the first provision, for covered inpatient and outpatient health services received from a provider that does not participate (accept assignment) with TRICARE. These provisions help ensure timely access to health care and maintain clinically appropriate continuity of health care to family members of Reservists and Guardsmen activated in support of a federal/contingency operation; limit the out-of-pocket health care expenses for those family members; and remove potential barriers to health care access by Guard and Reserve families.

Research in crisis areas indicate that survivors' responses to the forced disappearance of family members are similar to reactions to other traumatic events. The aim of this study was to determine the presence of symptoms of posttraumatic stress disorder (PTSD) in women with war missing family members in Bosnia and Herzegovina 18 years after the war in this region (1992-1995). The study included 160 women aged 47.1±14.0 from three regions of Bosnia and Herzegovina. It was carried out in the period from April 2010 to May 2011. Of the 160 participants, 120 women had a war missing family member and 40 women had no war missing family members. The Harvard Trauma Questionnaire (HTQ), the Beck Depression Inventory (BDI) and the Hamilton Anxiety Rating Scale (HAMA) were used for data collection. Basic socio-demographic data and data concerning the missing family members were also collected. Women with war missing family members experienced significantly more traumatic war experiences (18.43±5.27 vs 6.57±4.34, p<0.001). There was a significant difference between the two groups in the total PTSD score (2.48±0.59 vs 1.79±0.53, p<0.001), as well as in the intensity of depression (26.63±13.05 vs 10.32±6.58, p<0.001) and anxiety (21.0±10.69 vs 11.27±7.93, p<0.001). Anxiety and traumatic war experiences were significant predictors of PTSD in the group with war missing family members. Women with war missing family members showed significantly more severe PTSD symptoms. Based on the results of this study, it was determined that the forced disappearance of a family member is an ambiguous situation that can be characterized as a traumatic experience.

Central to the maintenance of genomic integrity is the cellular DNA damage response. Depending on the type of genotoxic stress and through the activation of multiple signaling cascades, it can lead to cell cycle arrest, DNA repair, senescence, and apoptosis. p19INK4d, a member of the INK4 family of CDK inhibitors, plays a dual role in the DNA damage response, inhibiting cell proliferation and promoting DNA repair. Consistently, p19INK4d has been reported to become upregulated in response to UV irradiation and a great variety of genotoxic agents. Here, this induction is shown to result from a transcriptional stimulatory mechanism that can occur at every phase of the cell cycle except during mitosis. Moreover, evidence is presented that demonstrates that E2F1 is involved in the induction of p19INK4d following UV treatment, as it is prevented by E2F1 protein ablation and DNA-binding inhibition. Specific inhibition of this regulation using triplex-forming oligonucleotides that target the E2F response elements present in the p19INK4d promoter also block p19INK4d upregulation and sensitize cells to DNA damage. These results constitute the first description of a mechanism for the induction of p19INK4d in response to UV irradiation and demonstrate the physiological relevance of this regulation following DNA damage.

From the Fifth Korea National Health and Nutrition Examination Survey dataset (KNHANES V) (2010-2012), we identified 363 RA patients and selected family members of these patients who were aged 20 years or older (n = 367). The control group was randomly sampled from members of families without RA patients and matched for sex and age (n = 1101). We compared the psychosocial characteristics of family members of RA patients with the control group. Additionally, serial conditional logistic regression models were performed to evaluate the factors that affect psychosocial status of the RA family members, after adjusting for covariates. No significant differences were found in socioeconomic status between the two groups. For psychological factors, stress (85.8 vs 74.7 %, p < 0.001) and depression (7.9 vs 3.3 %, p < 0.001) were more common in the family members of RA patients. The presence of a RA patient in the family showed a positive association with stress [odds ratio (OR) 2.07; 95 % confidence interval (CI) 1.48-2.88, p < 0.001] and depression (OR 2.59, CI 1.55-4.32, p < 0.001), after adjusting for socioeconomic status. Our data show that the family members of RA patients have an increased prevalence of stress and depression. Physicians who treat RA patients should also consider the needs and the burden of family members.

Aims The purpose of this quasi-experimental one group longitudinal study is to examine the effects of a family-based intervention program on diabetes self-management behaviors, HbA1c, other biomarkers, psychosocial factors and health-related quality of life in Hispanics with diabetes. Methods Adult patients with diabetes (n = 36) and family members (n = 37) were recruited from a community clinic in rural central North Carolina. Patients and family members attended an 8-week culturally tailored diabetes educational program taught in Spanish. Data was collected pre and post intervention for both patients and family members, with an additional data collection for patients 1 month post intervention. Results Most patients and family members were female and almost all were immigrants. HbA1c dropped by 0.41% on average among patients from pre-intervention to 1 month post intervention. Patients showed significant improvements in systolic blood pressure, diabetes self-efficacy diabetes knowledge, and physical and mental components of health-related quality of life. Higher levels of intake of healthy foods and performance of blood sugar tests and foot inspections were reported. Family members significantly lowered BMI and improved diabetes knowledge from pre- to immediate post-intervention. No significant changes in levels of physical activity were found among patients with diabetes or family members. Conclusions Findings suggest that including family members in educational interventions may provide emotional and psychological support to patients with diabetes, help to develop healthy family behaviors, and promote diabetes self-management.

Objectives To describe pre-loss and post-loss grief symptoms among family members of nursing home (NH) residents with advanced dementia, and to identify predictors of greater post-loss grief symptoms. Design Prospective cohort study. Setting 22 NHs in the greater Boston area. Participants 123 family members of NH residents who died with advanced dementia. Measurements Pre-loss grief was measured at baseline, and post-loss grief was measured 2 and 7 months post-loss using the Prolonged Grief Disorder scale. Independent variables included resident and family member sociodemographic characteristics, resident comfort, acute illness, acute care prior to death, family member depression, and family member understanding of dementia and of resident’s prognosis. Results Levels of pre-loss and post-loss grief were relatively stable from baseline to 7 months post-loss. Feelings of separation and yearning were the most prominent grief symptoms. After multivariable adjustment, greater pre-loss grief and the family member having lived with the resident prior to NH admission were the only factors independently associated with greater post-loss grief 7 months after resident death. Conclusions The pattern of grieving for some family members of NH residents with advanced dementia is prolonged and begins before resident death. Identification of family members at risk for post-loss grief during the pre-loss period may help guide interventions aimed at lessening post-loss grief. PMID:21606897

The presence of polyploid cells in the endocrine and exocrine pancreas has been reported for four decades. In rodents, pancreatic polyploidization is initiated after weaning and the number of polyploid cells increases with age. Surprisingly the molecular regulators and biological functions of polyploidization in the pancreas are still unknown. We discovered that atypical E2f activity is essential for polyploidization in the pancreas, using an inducible Cre/LoxP approach in new-born mice to delete ubiquitously the atypical E2f transcription factors, E2f7 and E2f8. In contrast to its critical role in embryonic survival, conditional deletion of both of both atypical E2fs in newborn mice had no impact on postnatal survival and mice lived until old age. However, deficiency of E2f7 or E2f8 alone was sufficient to suppress polyploidization in the pancreas and associated with only a minor decrease in blood serum levels of glucose, insulin, amylase and lipase under 4 hours starvation condition compared to wildtype littermates. In mice with fewer pancreatic polyploid cells that were fed ad libitum, no major impact on hormones or enzymes levels was observed. In summary, we identified atypical E2fs to be essential for polyploidization in the pancreas and discovered that postnatal induced loss of both atypical E2fs in many organs is compatible with life until old age.

We report a systematic study of the electronic structure of two members of the transition metal dihalide family, TiF 2 and TiCl 2. Using the configuration interaction method in large basis sets we investigated the lowest 15 states of TiF 2 and TiCl 2. We report bond lengths, frequencies and dissociation energies of both molecules. For TiF 2 we found a near degeneracy of the ground and the first excited state with a possible breakdown of the Born-Oppenheimer approximation.

ATAR, a novel tumor necrosis factor receptor family member, signals through TRAF2 and TRAF5.

Members of tumor necrosis factor receptor (TNFR) family signal largely through interactions with death domain proteins and TRAF proteins. Here we report the identification of a novel TNFR family member ATAR. Human and mouse ATAR contain 283 and 276 amino acids, respectively, making them the shortest known members of the TNFR superfamily. The receptor is expressed mainly in spleen, thymus, bone marrow, lung, and small intestine. The intracellular domains of human and mouse ATAR share only 25% identity, yet both interact with TRAF5 and TRAF2. This TRAF interaction domain resides at the C-terminal 20 amino acids. Like most other TRAF-interacting receptors, overexpression of ATAR activates the transcription factor NF-kappaB. Co-expression of ATAR with TRAF5, but not TRAF2, results in synergistic activation of NF-kappaB, suggesting potentially different roles for TRAF2 and TRAF5 in post-receptor signaling.

1991-01-01

Patients in a persistent vegetative state (PVS) constituted approximately 3% of the population in four Milwaukee nursing homes. In order to understand family members' attitudes and reactions toward such patients, 33 (92%) of 36 family members of patients in PVS contacted were studied. The age of the patients ranged from 19 to 95 with a mean age of 73.4 +/- 17.2 years, and family members' ages ranged from 41 to 89 with a mean age of 61.8 +/- 3.3 years. The etiology of the PVS varied from dementia to cerebral trauma. The mean duration of the PVS was 54 +/- 8.4 months (range 12 to 204). Family members reported that they visited patients 260 times during the first year following the onset of the PVS and were still visiting at a rate of 209 visits yearly at the time of the interview. There was no significant correlation between the frequency of the family members visits and the duration of the PVS, the patient's or family member's age, or the family member's relationship to the patient. Ninety percent of patients were considered by family members to have some awareness of pain, light or darkness, environment, taste, verbal conversation, or the family member's presence. Most family members thought they understood the patient's medical condition, and the majority did not expect the patient to improve. Nevertheless, the majority of family members wanted the patient to undergo therapeutic interventions, including transfer to the acute hospital and surgery.(ABSTRACT TRUNCATED AT 250 WORDS)

Export of l-Isoleucine from Corynebacterium glutamicum: a Two-Gene-Encoded Member of a New Translocator Family

Bacteria possess amino acid export systems, and Corynebacterium glutamicum excretes l-isoleucine in a process dependent on the proton motive force. In order to identify the system responsible for l-isoleucine export, we have used transposon mutagenesis to isolate mutants of C. glutamicum sensitive to the peptide isoleucyl-isoleucine. In one such mutant, strong peptide sensitivity resulted from insertion into a gene designated brnF encoding a hydrophobic protein predicted to possess seven transmembrane spanning helices. brnE is located downstream of brnF and encodes a second hydrophobic protein with four putative membrane-spanning helices. A mutant deleted of both genes no longer exports l-isoleucine, whereas an overexpressing strain exports this amino acid at an increased rate. BrnF and BrnE together are also required for the export of l-leucine and l-valine. BrnFE is thus a two-component export permease specific for aliphatic hydrophobic amino acids. Upstream of brnFE and transcribed divergently is an Lrp-like regulatory gene required for active export. Searches for homologues of BrnFE show that this type of exporter is widespread in prokaryotes but lacking in eukaryotes and that both gene products which together comprise the members of a novel family, the LIV-E family, generally map together within a single operon. Comparisons of the BrnF and BrnE phylogenetic trees show that gene duplication events in the early bacterial lineage gave rise to multiple paralogues that have been retained in α-proteobacteria but not in other prokaryotes analyzed.

Although most patients express a preference to die at home, many (over 30 percent) still die in hospital. This study's purpose was to explore the experience of hospital death from the perspective of patients' family members. interviews were conducted with family members of patients who had died at hospitals affiliated with a large tertiary referral centre in the United States. Content analysis was used to analyze findings. We interviewed 30 family members by phone. Themes were arranged by time frame: before death, time of death, and after death. Families do not interpret clinical cues leading up to death in the same way healthcare providers do; families need clear and direct explanations from providers. Clinicians should assess patient and family understandings of prognosis and communicate clearly and directly. Family members value being with their loved one at the time of death, and they value spending time with the body after death; this should be facilitated in clinical practice.

Two main mechanisms of protein turnover exist in eukaryotic cells: the ubiquitin-proteasome system and the autophagy-lysosomal pathway. Autophagy is an emerging important constituent of many physiological and pathological processes, such as response to nutrient deficiency, programmed cell death and innate immune response. In mammalian cells the selectivity of autophagy is ensured by the presence of cargo receptors, such as p62/SQSTM1 and NBR1, responsible for sequestration of the ubiquitinated proteins. In plants no selective cargo receptors have been identified yet. The present report indicates that structural and functional homologs of p62 and NBR1 proteins exist in plants. The tobacco protein, named Joka2, has been identified in yeast two-hybrid search as a binding partner of a small coiled-coil protein, a member of UP9/LSU family of unknown function, encoded by the UP9C gene strongly and specifically induced during sulfur deficiency. The typical domains of p62 and NBR1 are conserved in Joka2. Similarly to p62, Joka2-YFP has dual localization (cytosolic speckles and the nucleus); it forms homodimers and interacts with a member of the ATG8 family. Increased expression of Joka2 and ATG8f was observed in roots of tobacco plants grown for two days in nutrient-deficient conditions. Constitutive ectopic expression of Joka2-YFP in tobacco resulted in attenuated response (manifested by lesser yellowing of the leaves) to nutrient deficiency. In conclusion, Joka2, and presumably the process of selective autophagy, might constitute an important part of plant response to environmental stresses. PMID:21670587

Family members are often the primary caregiver for autistic adults and this responsibility may impact on the carer's wellbeing and quality of life. 109 family members of autistic adults completed an online survey assessing their wellbeing relating to their caring role for their autistic relative. Family members who were supporting an autistic relative with co-occurring mental health difficulties and who they reported as unprepared for the future, self-reported higher levels of worry, depression, anxiety and stress, and poorer quality of life. These findings emphasise the importance of support for family members of autistic adults, whether through external services to support their relative or individual mental health support for the carer.

E2F4 is required for early eye patterning.

Increasingly, studies reveal novel functions for cell cycle proteins during development. Here, we investigated the role of E2F4 in eye development. E2F4-deficient mouse embryos exhibit severe early eye patterning defects, which are evident from embryonic day 11.5 and characterized by aberrant shape of the optic cup, coloboma as well as abnormal eye pigmentation. Loss of E2F4 is associated with proximal-distal patterning defects in the optic vesicle. These defects are characterized by the expansion of optic stalk marker gene expression to the optic cup and reduced expression of ventral optic cup markers. These defects are associated with a split of Shh expression domain at the ventral midline of the forebrain and expansion of the Shh activity into the ventral optic cup. Despite these patterning defects, early neuronal differentiation and Shh expression in the retina are not affected by E2F4 deletion. Overall, the results of our studies show a novel role of E2F4 in the early eye development. 2009 S. Karger AG, Basel.

Expression of the F-Box protein Leaf Curling Responsiveness (LCR) is regulated by microRNA, miR394, and alterations to this interplay in Arabidopsis thaliana produce defects in leaf polarity and shoot apical meristem organization. Although the miR394-LCR node has been documented in Arabidopsis, the identification of proteins targeted by LCR F-box itself has proven problematic. Here, a proteomic analysis of shoot apices from plants with altered LCR levels identified a member of the Latex Protein (MLP) family gene as a potential LCR F-box target. Bioinformatic and molecular analyses also suggested that other MLP family members are likely to be targets for this post-translational regulation. Direct interaction between LCR F-Box and MLP423 was validated. Additional MLP members had reduction in protein accumulation, in varying degrees, mediated by LCR F-Box. Transgenic Arabidopsis lines, in which MLP28 expression was reduced through an artificial miRNA technology, displayed severe developmental defects, including changes in leaf patterning and morphology, shoot apex defects, and eventual premature death. These phenotypic characteristics resemble those of Arabidopsis plants modified to over-express LCR Taken together, the results demonstrate that MLPs are driven to degradation by LCR, and indicate that MLP gene family is target of miR394-LCR regulatory node, representing potential targets for directly post-translational regulation mediated by LCR F-Box. In addition, MLP28 family member is associated with the LCR regulation that is critical for normal Arabidopsis development. © 2016 by The American Society for Biochemistry and Molecular Biology, Inc.

This study evaluates the role of older family members as providers of social resources within familial network systems affected by an inherited cancer susceptibility syndrome.  Respondents who previously participated in a study that involved genetic counseling and testing for Lynch syndrome and their family network members were invited to participate in a onetime telephone interview about family communication. A total of 206 respondents from 33 families identified 2,051 social relationships (dyads). Nineteen percent of the respondents and 25% of the network members were older (≥60 years). Younger respondents (≤59 years) were more likely to nominate older network members as providers of social resources than younger members: instrumental support (odds ratio [OR] = 1.68), emotional support (OR = 1.71), help in crisis situation (OR = 2.04), and dependability when needed (OR = 2.15). Compared with younger network members, older members were more likely to be listed as encouragers of colon cancer screening by both younger (OR = 3.40) and older respondents (OR = 1.90) independent of whether support exchange occurred in the relationship. Engaging older network members in health interventions to facilitate screening behaviors and emotional well-being of younger members within families affected by inherited conditions may be beneficial. Findings can be used to empower older individuals about their important social roles in enhancing the well-being of their family members and to inform younger individuals about their older relatives' resourcefulness to facilitate positive social interactions.

Silencing of E2F3 suppresses tumor growth of Her2+ breast cancer cells by restricting mitosis.

2015-11-10

The E2F transcriptional activators E2F1, E2F2 and E2F3a regulate many important cellular processes, including DNA replication, apoptosis and centrosome duplication. Previously, we demonstrated that silencing E2F1 or E2F3 suppresses centrosome amplification (CA) and chromosome instability (CIN) in Her2+ breast cancer cells without markedly altering proliferation. However, it is unknown whether and how silencing a single E2F activator, E2F3, affects malignancy of human breast cancer cells. Thus, we injected HCC1954 Her2+ breast cancer cells silenced for E2F3 into mammary fat pads of immunodeficient mice and demonstrated that loss of E2F3 retards tumor growth. Surprisingly, silencing of E2F3 led to significant reductions in mitotic indices relative to vector controls, while the percentage of cells undergoing S phase were not affected. Nek2 is a mitotic kinase commonly upregulated in breast cancers and a critical regulator of Cdk4- or E2F-mediated CA. In this report, we found that Nek2 overexpression rescued back the CA caused by silencing of shE2F3. However, the effects of Nek2 overexpression in affecting tumor growth rates of shE2F3 and shE2F3; GFP cells were inconclusive. Taken together, our results indicate that E2F3 silencing decreases mammary tumor growth by reducing percentage of cells undergoing mitosis.

Objective Characterize the process of family vegetable selection (especially cruciferous, deep orange, and dark green leafy vegetables); demonstrate the usefulness of Exchange Theory (how family norms and past experiences interact with rewards and costs) for interpreting the data. Design Eight focus groups, two with each segment (men/women vegetable-likers/dislikers based on a screening form). Participants completed a vegetable intake form. Setting Rural Appalachian Pennsylvania. Participants 61 low-income, married/cohabiting men (n=28) and women (n=33). Analysis Thematic analysis within Exchange Theory framework for qualitative data. Descriptive analysis, t-tests and chi-square tests for quantitative data. Results Exchange Theory proved useful for understanding that regardless of sex or vegetable-liker/disliker status, meal preparers see more costs than rewards to serving vegetables. Past experience plus expectations of food preparer role and of deference to family member preferences supported a family norm of serving only vegetables acceptable to everyone. Emphasized vegetables are largely ignored due to unfamiliarity; family norms prevented experimentation and learning through exposure. Conclusions and Implications Interventions to increase vegetable consumption of this audience could 1) alter family norms about vegetables served, 2) change perceptions of past experiences, 3) reduce social and personal costs of serving vegetables and 4) increase tangible and social rewards of serving vegetables.

E2F Activators Signal and Maintain Centrosome Amplification in Breast Cancer Cells

Centrosomes ensure accurate chromosome segregation by directing spindle bipolarity. Loss of centrosome regulation results in centrosome amplification, multipolar mitosis and aneuploidy. Since centrosome amplification is common in premalignant lesions and breast tumors, it is proposed to play a central role in breast tumorigenesis, a hypothesis that remains to be tested. The coordination between the cell and centrosome cycles is of paramount importance to maintain normal centrosome numbers, and the E2Fs may be responsible for regulating these cycles. However, the role of E2F activators in centrosome amplification is unclear. Because E2Fs are deregulated in Her2+ cells displaying centrosome amplification, we addressed whether they signal this abnormal process. Knockdown of E2F1 or E2F3 in Her2+ cells decreased centrosome amplification without significantly affecting cell cycle progression, whereas the overexpression of E2F1, E2F2, or E2F3 increased centrosome amplification in MCF10A mammary epithelial cells. Our results revealed that E2Fs affect the expression of proteins, including Nek2 and Plk4, known to influence the cell/centrosome cycles and mitosis. Downregulation of E2F3 resulted in cell death and delays/blocks in cytokinesis, which was reversed by Nek2 overexpression. Nek2 overexpression enhanced centrosome amplification in Her2+ breast cancer cells silenced for E2F3, revealing a role for the E2F activators in maintaining centrosome amplification in part through Nek2.

We used a modified multitrait-multimethod confirmatory factor analysis that (a) isolated for each family member's 6 reports of family dysfunction the nonshared variance (a combination of variance idiosyncratic to the individual and measurement error) from variance shared by 1 or more family members and (b) extracted common variance across each family member's set of nonshared variances. The sample included 128 families from a U.S. East Coast metropolitan area. Each family member's unique perspective generalized across his or her different reports of family dysfunction and accounted for a sizable proportion of his or her own variance in reports of family dysfunction. In addition, after holding level of dysfunction constant across families and controlling for a family's shared variance (agreement regarding family dysfunction), each family member's unique perspective was associated with his or her own adjustment. Future applications and competing alternatives for what these "unique perspectives" reflect about the family are discussed. PsycINFO Database Record (c) 2012 APA, all rights reserved.

The mechanisms underlying cell death during oxygen deprivation are unknown. We report here a model for oxygen deprivation-induced apoptosis. The death observed during oxygen deprivation involves a decrease in the mitochondrial membrane potential, followed by the release of cytochrome c and the activation of caspase-9. Bcl-XL prevented oxygen deprivation-induced cell death by inhibiting the release of cytochrome c and caspase-9 activation. The ability of Bcl-XL to prevent cell death was dependent on allowing the import of glycolytic ATP into the mitochondria to generate an inner mitochondrial membrane potential through the F1F0-ATP synthase. In contrast, although activated Akt has been shown to inhibit apoptosis induced by a variety of apoptotic stimuli, it did not prevent cell death during oxygen deprivation. In addition to Bcl-XL, cells devoid of mitochondrial DNA (ρ° cells) that lack a functional electron transport chain were resistant to oxygen deprivation. Further, murine embryonic fibroblasts from bax−/− bak−/− mice did not die in response to oxygen deprivation. These data suggest that when subjected to oxygen deprivation, cells die as a result of an inability to maintain a mitochondrial membrane potential through the import of glycolytic ATP. Proapoptotic Bcl-2 family members and a functional electron transport chain are required to initiate cell death in response to oxygen deprivation. PMID:11739725

To describe the impact of the cancer experience on the health behaviors of survivors' family members and to determine factors associated with family members' intentions for health behavior change. Descriptive, cross-sectional, correlational. A National Cancer Institute-designated comprehensive cancer center in the midwestern United States. 39 family members and 50 patients with diagnoses of breast, colorectal, head and neck, lung, or prostate cancer who were completing definitive cancer treatment. Patients and family members were approached in the clinic at three weeks or fewer before the completion of their course of treatment. Family members completed surveys and a structured interview in person or via telephone. Intention, perceived benefit, and confidence about eating a healthful diet, physical activity, and smoking cessation; emotional distress; and family cohesion, conflict, and expressiveness. Family members had high ratings for intention, perceived benefit, and confidence related to the behaviors of eating a healthful diet and performing 30 minutes of daily moderate-intensity physical activity. They also had high ratings for the extent to which the cancer experience had raised awareness of their cancer risk and made them consider undergoing screening tests for cancer; ratings were lower for making changes in their health behaviors. Family members expressed strong intentions to engage in health-promoting behaviors related to physical activity and nutrition at the post-treatment transition. Oncology nurses are in a key position to engage family members and patients in behavior change. Nurses should assess family members at the completion of treatment for distress and provide interventions to influence the trajectory of distress in survivorship.

To provide high-quality and effective cancer care, problems and unmet needs of family members during their relatives' hospitalisation have to be identified as well. The aims were to determine how needs of family members of patients with terminal cancer are met and to analyse factors that influence them. The needs were assessed with the Family Inventory of Needs. Each item (n = 20) represents one need of family members, for which the importance and satisfaction are rated. The study comprised 270 family members of hospitalised advanced cancer patients staying in the University Hospital Ostrava who were receiving palliative care. The family members preferred sufficient basic information and patient comfort. The unmet needs were support of hope (73%) and provision of information (65%). The unmet needs were more frequently identified by women, individuals with lower education, younger persons, unemployed, patients' children and family members of patients with generally unfavourable health status (P < 0.05). There was a correlation between lower quality of life and higher numbers of unmet needs. Targeted interventions aimed at meeting important needs of the family members may improve their quality of life. © 2016 John Wiley & Sons Ltd.

The purpose of this study was to examine the reliability and validity of the Toolkit After-Death Bereaved Family Member Interview to measure quality of care at the end of life from the unique perspective of family members. The survey included proposed problem scores (a count of the opportunity to improve the quality of care) and scales. Data were collected through a retrospective telephone survey with a family member who was interviewed between 3 and 6 months after the death of the patient. The setting was an outpatient hospice service, a consortium of nursing homes, and a hospital in New England. One hundred fifty-six family members from across these settings participated. The 8 proposed domains of care, as represented by problem scores or scales, were based on a conceptual model of patient-focused, family-centered medical care. The survey design emphasized face validity in order to provide actionable information to health care providers. A correlational and factor analysis was undertaken of the 8 proposed problem scores or scales. Cronbach's alpha scores varied from 0.58 to 0.87, with two problem scores (each of which had only 3 survey items) having a low alpha of 0.58. The mean item-to-total correlations for the other problem scores varied from 0.36 to 0.69, and the mean item-to-item correlations were between 0.32 and 0.70. The proposed problem scores or scales, with the exception of closure and advance care planning, demonstrated a moderate correlation (i.e., from 0.44 to 0.52) with the overall rating of satisfaction (as measured by a five-point, "excellent" to "poor" scale). Family members of persons who died with hospice service reported fewer problems in each of the six domains of medical care, gave a higher rating of the quality of care, and reported higher self-efficacy in caring for their loved ones. These results indicate that 7 of the 8 proposed problem scores or scales demonstrated psychometric properties that warrant further testing. The domain of

In this study, we explored stigma by association, family burden, and their impact on the family members of people with mental illness. We also studied the ways in which family members coped with these phenomena. We conducted semistructured interviews with 23 immediate family members of people with mental illness. Participants reported various experiences of stigma by association and family burden. Social exclusion, being blamed, not being taken seriously, time-consuming caregiving activities, and exhaustion appeared to be the predominant forms of stigma by association and family burden experienced by the participants. The participants used problem-focused and emotion-focused coping strategies, separately or simultaneously, to cope with the negative impact of stigma by association and family burden. The results suggest that family members should have access to services to address these problems. Social, instrumental, and emotional support should be given to family members by community members and mental health professionals.

The characteristics of the F2 layer parameters NmF2 and hmF2 over Dibrugarh (27.5° N, 95° E, 17° N geomagnetic, 43° dip) measured by a Canadian Advanced Digital Ionosonde (CADI) for the period of August 2010 to July 2014 are reported for the first time from this low mid-latitude station lying within the daytime peak of the longitudinal wave number 4 structure of equatorial anomaly (EIA) around the northern edge of anomaly crest. Equinoctial asymmetry is clearly observed at all solar activity levels whereas the midday winter anomaly is observed only during high solar activity years and disappears during the temporary dip in solar activity in 2013 but forenoon winter anomaly can be observed even at moderate solar activity. The NmF2/hmF2 variations over Dibrugarh are compared with that of Okinawa (26.5° N, 127° E, 17° N geomagnetic), and the eastward propagation speed of the wave number 4 longitudinal structure from 95° E to 127° E is estimated. The speed is found to be close to the theoretical speed of the wave number 4 (WN4) structure. The correlation of daily NmF2 over Dibrugarh and Okinawa with solar activity exhibits diurnal and seasonal variations. The highest correlation in daytime is observed during the forenoon hours in equinox. The correlation of daily NmF2 (linear or non-linear) with solar activity exhibits diurnal variation. A tendency for amplification with solar activity is observed in the forenoon and late evening period of March equinox and the postsunset period of December solstice. NmF2 saturation effect is observed only in the midday period of equinox. Non-linear variation of neutral composition at higher altitudes and variation of recombination rates with solar activity via temperature dependence may be related to the non-linear trend. The noon time maximum NmF2 over Dibrugarh exhibits better correlation with equatorial electrojet (EEJ) than with solar activity and, therefore, new low-latitude NmF2 index is proposed taking both solar

Denomme, William James; Benhanoh, Orry

2017-08-01

There is a growing body of research demonstrating that families of individuals with substance use and concurrent disorders (SUCD) experience a wide range of biopsychosocial problems that significantly impedes their quality of life and health. However, there has been a relative lack of treatment programs primarily focused on improving the well-being and quality of life of these family members. The current study assessed the efficacy of such a program at reducing stress, increasing perceived social support from family and friends, and increasing general, dyadic, and self-rated family functioning within these concerned family members. A sample of 125 family members of individuals with SUCDs was recruited, of which 97 participated in the treatment program and 28 were used as the comparison group. Results indicated that the treatment program significantly reduced stress, increased perceived social support from family and friends, and increased general, dyadic and self-rated family functioning. A perceived personal benefits questionnaire demonstrated that participants had a better understanding of SUCDs, better coping capabilities in regard to emotional difficulties, adopted stronger coping methods, participated in more leisure activities, and improved their relationship with the individual with a SUCD. The results of the current study further demonstrate the need to implement more of these family-member oriented psycho-educational treatment programs. Copyright © 2017 Elsevier Inc.

Studies have consistently shown that both the subjective and objective dimensions of burden among family members of schizophrenia patients and other psychiatric disorders are prevalent. However, as most of these reports were from western societies, we lack information on the subject in developing countries. The study was conducted within the framework of the ongoing epidemiological study of course and outcome of schizophrenia and bipolar disorders in a rural population of 15-49 years of age. Three hundred and one cases of schizophrenia and their close relatives participated in the study. Family burden is a common problem of relatives of cases with schizophrenia. Financial difficulty is the most frequently endorsed problem among the family burden domains (74.4 %). Relatives of female cases suffered significantly higher social burden (Z = 2.103; p = 0.036). Work (Z = 2.180; p = 0.029) and financial (Z = 2.088; p = 0.037) burdens affected female relatives more often than males. Disorganised symptoms were the most important factors affecting the family members in all family burden domains. Prayer was found to be the most frequently used coping strategy in work burden (adj. OR = 1.99; 95 % CI = 1.08-3.67; p = 0.026). Negative impact of schizophrenia on family members is substantial even in traditional societies such as those in Ethiopia where family network is strong and important. The scarce existing services in the developing countries should include family interventions and support at least in the form of educating the family members about the nature of schizophrenia illness and dealing with its stigma and family burden.

This article explores the association of people who inject drugs and their family members in terms of mental health and family relations. The objective was to understand the family context and its impact on people who inject drugs in a family-oriented culture in Vietnam. Cross-sectional assessment data were gathered from 83 people who inject drugs and 83 of their family members recruited from four communes in Phú Thọ province, Vietnam. Depressive symptoms and family relations were measured for both people who inject drugs and family members. Internalized shame and drug-using behavior were reported by people who inject drugs, and caregiver burden was reported by family members. We found that higher level of drug using behavior of people who inject drugs was significantly associated with higher depressive symptoms and lower family relations reported by themselves as well as their family members. Family relations reported by people who inject drugs and their family members were positively correlated. The findings highlight the need for interventions that address psychological distress and the related challenges faced by family members of people who inject drugs. The article has policy implication which concludes with an argument for developing strategies that enhance the role of families in supporting behavioral change among people who inject drugs.

In the Pseudomonas bacterial genomes, the PhzF proteins are involved in the production of phenazine derivative antibiotic and antifungal compounds. The PhzF superfamily however also encompasses proteins in all genomes from bacteria to eukaryotes, for which no function has been assigned. We have determined the three dimensional crystal structure at 2.05 A resolution of YHI9, the yeast member of the PhzF family. YHI9 has a fold similar to bacterial diaminopimelate epimerase, revealing a bimodular structure with an internal symmetry. Residue conservation identifies a putative active site at the interface between the two domains. Evolution of this protein by gene duplication, gene fusion and domain swapping from an ancestral gene containing the "hot dog" fold, identifies the protein as a "kinked double hot dog" fold.

Objective Protein disulfide isomerase (PDI) is an oxidoreductase that is overexpressed in several cancers. PDI family members (PDIs) play a role in various diseases including cancer. Select PDIs were reported as useful markers in other cancers but their expression in ovarian cancer has not been thoroughly assessed. We sought to evaluate the expression of PDI, PDIA6, PDIR, ERp57, ERp72 and AGR3 in ovarian cancer patient samples and examine their prognostic significance. Methods TMA samples from 415 tissues collected from three cancer centers (UM, USC, and KCCRI) were used to assess the expression levels of PDI family proteins using IHC. Results We observed significant increases in PDI (p = 9.16E-36), PDIA6 (p = 5.51E-33), PDIR (p = 1.81E-12), ERp57 (p = 9.13E-07), ERp72 (p = 3.65E-22), and AGR3 (p = 4.56E-24) expression in ovarian cancers compared to normal tissues. Expression of PDI family members also increases during disease progression (p <0.001). All PDI family members are overexpressed in serous ovarian cancer (p<0.001). However, PDI, PDIA6, PDIR, ERp72 and AGR3 are more significantly overexpressed (p<0.001) than ERp57 (p<0.05) in clear cell ovarian carcinoma. Importantly, overexpression of PDI family members is associated with poor survival in ovarian cancer (p = 0.045 for PDI, p = 0.047 for PDIR, p = 0.037 for ERp57, p = 0.046 for ERp72, p = 0.040 for AGR3) with the exception of PDIA6 (p = 0.381). Conclusions Our findings demonstrate that select PDI family members (PDI, PDIR, ERp72, ERp57 and AGR3) are potential prognostic markers for ovarian cancer. PMID:29262583

To understand technical nursing students' meaning of interacting with family members of hospitalized children. Symbolic Interactionism was used as the theoretical framework and Qualitative Content Analysis was the methodological procedure. A total of eight graduates from an institution situated in the city of Osasco, Sao Paulo state, participated in this study. Data were collected through semi-structured interviews. A total of five representative themes were revealed: Dealing with difficult situations with family members; Perceiving oneself to be unprepared to interact with family members; Family members being a helpful tool; Developing strategies to obtain a good interaction with family members; and Teachers being facilitators of the interaction with family members. To be acquainted with this experience has led to the understanding of the need to include the theme of family care in the curriculum of the Technical Nursing Course. Additionally, the present study contributed to reflections on the importance of such knowledge for this population and to the development of future studies, as this theme has been scarcely explored in the literature.

PROBLEM The family members of adolescents diagnosed with Disruptive Behavior Disorders (DBD) experience profound stress and burden. Despite the need for empirically supported interventions that address the challenges faced by these family members, few such interventions are available. METHODS In this qualitative descriptive study, we conducted in-depth interviews with 15 families of adolescents diagnosed with DBD. We asked the family members to identify what types of mental health services they needed and to describe the ‘ideal” program that would best address their concerns. FINDINGS Family members identified several intervention modalities that would fit their needs including multi-family groups, family therapy, individual therapy, and community-based hotlines. They indicated that programs should address the following topics: family communication, conflict resolution, education about DBD, and strategies to improve interactions with child service agencies. CONCLUSIONS Clinicians should recognize that all family members may need support to manage the stressors associated with caring for or living with adolescents with DBD. When working with families, clinicians should provide information about the etiology and management of DBD, help navigate interactions with child service agencies, and employ strategies to improve family communication and functioning.

Silent saviours: family members in a Bangladeshi hospital.

Zaman, Shahaduz

2013-01-01

This paper is based on a larger ethnographic study that was conducted in a public hospital in Bangladesh and explores the experiences of family members who have kin in the hospital. The paper shows that family members are an integral part of the informal organisation of the Bangladeshi hospital. The obvious presence of family members in the ward has both structural and cultural dimensions. On one hand, it demonstrates the scarcity of manpower in the hospital, which is a result of general poverty in the country, and on the other hand, it manifests the deep cultural value of family in Bangladeshi life. The paper also shows how the hospital is an ambiguous space where both biomedical and domestic practices function simultaneously.

The frequency and extent of the existence of a familial suicide prevention plan may differ across cultures. The aim of this work was, therefore, to determine how common it was for families to develop a suicide prevention plan and to compare the main measures used by families with and without such a plan, after an attempt to commit suicide was made by a member of a family living in a rural area of Korea. On the basis of the presence or absence of a familial suicide prevention plan, we compared 50 recruited families that were divided into 2 groups, with Group A (31 families) employing a familial suicide prevention plan after a suicide attempt by a family member, and Group B (19 families) not doing so. The strategy that was employed most frequently to prevent a reoccurrence among both populations was promoting communication among family members, followed by seeking psychological counseling and/or psychiatric treatment. Contrary to our expectation, the economic burden from medical treatment after a suicide attempt did not influence the establishment of a familial suicide prevention plan. It is a pressing social issue that 38% (19 of 50) of families in this study did not employ a familial suicide prevention plan, even after a family member had attempted suicide. Regional suicide prevention centers and/or health authorities should pay particular attention to these patients and their families.

Anxiety is shared by patients and family members (FMs) and can increase throughout the FMs waiting during invasive cardiac procedures (ICP). The purpose of this study was to measure the effects of an informational report (IR) and a postprocedure visit (PPV), on the anxiety of waiting FMs. There were 151 FMs assigned to 3 groups; Group 1 (50 FMs: standard of care [SOC]), Group 2 (50 FMs: SOC + IR), and Group 3 (51 FMs: SOC + IR + PPV). Pre/ postvariables measured were: blood pressure (BP), heart rate (HR), skin temperature (ST), and anxiety. When comparing the BP, HR, ST, and anxiety there were no differences between groups with either SOC or IR. There was a significant reduction in anxiety, from baseline to the PPV in Group 3 (F = 10.1; p < .000). A PPV had an impact on FMs and a PPV should be incorporated as a nursing intervention during ICP.

Purpose/Objectives To describe the impact of the cancer experience on the health behaviors of survivors’ family members and to determine factors associated with family members’ intentions for health behavior change. Design Descriptive, cross-sectional, correlational study. Setting A National Cancer Institute-designated comprehensive cancer center in the Midwestern United States. Sample 39 family members and 50 patients with diagnoses of breast, colon, head and neck, lung, or prostate cancer who were completing definitive cancer treatment. Methods Patients and family members were approached in the clinic at 3 weeks or less before the completion of their course of treatment. Family members completed surveys and a structured interview in-person or via telephone. Main Research Variables Intention, perceived benefit, and confidence for eating a healthy diet, physical activity, and smoking cessation; emotional distress; and family cohesiveness, conflict, and expressiveness. Findings Family members had, on average, high ratings for intention, perceived benefit, and confidence related to behaviors of eating a healthy diet and doing 30 minutes of daily moderate physical activity. They also had high ratings for the extent to which the cancer experience raised their awareness of their own cancer risk and made them think about having screening tests; ratings were lower for making changes in their health behaviors. Distress scores of family members were high at the completion of cancer treatment. Greater intention for physical activity and nutrition was associated with greater perceived benefit and confidence. Higher scores for family expressiveness was associated with intention for nutrition. Greater intention for smoking cessation was associated only with confidence. Conclusions Family members expressed strong intentions to engage in health-promoting behaviors related to physical activity and nutrition at the transition to post-treatment survivorship.

Providing recognition and simple information can be powerful and reassure a family member who is anxious and worried about an ill relative. While "answers" concerning the procedure are often not available, providing information that is available--the locations of the rest rooms and coffee shop; approximately how long the procedure will take; where to wait; and the process involved in the radiological procedure, reading and getting the results--can give some feeling of control, and thus reduce feelings of powerlessness. Most importantly, family members who are recognized and included with the patient in the treatment process will be reassured of the competency of the staff and gain hopefulness about the outcome of the diagnostic and treatment experience. And providing hope in the healthcare setting is a radiology professional's most important job.

A number of advanced cancer patients are suffering from physical and psychosocial burdens because of cancer cachexia, and these burdens also greatly impact on their family members and relationships between patients and family members. It is necessary to consider the psychosocial impact of cancer cachexia on family members of advanced cancer patients. A cross-sectional anonymous nationwide survey was conducted involving 925 bereaved family members of cancer patients who had been admitted to 133 inpatient hospices throughout Japan. A total of 702 bereaved family members returned the questionnaires (response rate, 75.9%). Concerning eating-related distress, 'I served what the patient wanted without consideration of calories and nutritional composition' was highest (75.1%), and 'I tried making many kinds of meals for the patient' and 'I was concerned about planning meals for the patient every day' followed (63.0% and 59.4%, respectively). The top 5 of the 19 items were categorized as 'fighting back'. Need for nutritional support was high (72.2%), and need for explanations about the reasons for anorexia and weight loss of patients was moderate (41.4%). Explanatory factor analysis of eating-related distress identified the following four domains: (factor 1) feeling that family members forced the patient to eat to avoid death, (factor 2) feeling that family members made great efforts to help the patient eat, (factor 3) feeling that eating was a cause of conflicts between the patient and family members, and (factor 4) feeling that correct information was insufficient. Results of multiple logistic regression analysis showed that spouse, fair/poor mental status, factors 1, and 4 were identified as independent determinants of major depression {odds ratio [OR] 3.27 [95% confidence interval (CI) 1.24-8.60], P  = 0.02; OR 4.50 [95% CI 2.46-8.25], P  < 0.001; OR 2.51 [95% CI 1.16-5.45], P  = 0.02; OR 2.33 [95% CI 1.13-4.80], P  = 0.02, respectively}.

Summary The mechanisms that underlie and dictate the different biological outcomes of E2F-1 activity have yet to be elucidated. We describe the residue-specific methylation of E2F-1 by the asymmetric dimethylating protein arginine methyltransferase (PRMT) 1 and symmetric dimethylating PRMT5, and relate the marks to different functional consequences of E2F-1 activity. Methylation by PRMT1 hinders methylation by PRMT5, which augments E2F-1-dependent apoptosis, whereas PRMT5-dependent methylation favours proliferation by antagonising methylation by PRMT1. The ability of E2F-1 to prompt apoptosis in DNA damaged cells coincides with enhanced PRMT1 methylation. In contrast, cyclin A binding to E2F-1 impedes PRMT1 methylation and augments PRMT5 methylation, thus ensuring that E2F-1 is locked into its cell cycle progression mode. The Tudor domain protein p100-TSN reads the symmetric methylation mark, and binding of p100-TSN down-regulates E2F-1 apoptotic activity. Our results define an exquisite level of precision in the reader-writer interplay that governs the biological outcome of E2F-1 activity. PMID:24076217

Among Hispanics, the family is viewed as the primary care giver for seriously mentally ill family members. This paper reports on a study of minority families' conceptions of serious mental illness, of their interaction with mental health resources, and on the burdens experienced by families in caring for a seriously mentally ill family member. The focus of this paper is on Hispanic families in New Jersey, with some comparative data from other ethnic group families. Families' conceptions of serious mental illness are explored and analyzed to demonstrate the importance of concepts of nervios and fallo mental in shaping families' responses to their ill family member. Social support systems for families are also explored with particular attention to the role of religious institutions and religious healing as a major source of solace.

The frequency and extent of the existence of a familial suicide prevention plan may differ across cultures. The aim of this work was, therefore, to determine how common it was for families to develop a suicide prevention plan and to compare the main measures used by families with and without such a plan, after an attempt to commit suicide was made by a member of a family living in a rural area of Korea. On the basis of the presence or absence of a familial suicide prevention plan, we compared 50 recruited families that were divided into 2 groups, with Group A (31 families) employing a familial suicide prevention plan after a suicide attempt by a family member, and Group B (19 families) not doing so. The strategy that was employed most frequently to prevent a reoccurrence among both populations was promoting communication among family members, followed by seeking psychological counseling and/or psychiatric treatment. Contrary to our expectation, the economic burden from medical treatment after a suicide attempt did not influence the establishment of a familial suicide prevention plan. It is a pressing social issue that 38% (19 of 50) of families in this study did not employ a familial suicide prevention plan, even after a family member had attempted suicide. Regional suicide prevention centers and/or health authorities should pay particular attention to these patients and their families. PMID:26130963

In intensive care environments, patients' families are often encouraged to participate in their loved one's care; however, many family members feel anxious, depressed, and unsure about how to help patients. To determine (1) the feasibility of teaching family members a simple intervention combining hand massage with essential oils in a trauma intensive care unit and (2) an effect size for use in designing a more powerful trial. A quasi-experimental pilot study of the effect of a family-delivered touch treatment on anxiety and depression of family members of patients. Fifteen family members were assigned to a treatment group, and 15 family members were assigned to a control group. The treatment consisted of the application of hand massage with essential oils for 6 sessions. Each session lasted 5 minutes and was presented twice a day for 3 days. The 5-minute intervention was associated with positive change in anxiety and depression scores on the Hospital Anxiety and Depression Scale (HADS) among family members visiting patients. The magnitude of change (improvement) in anxiety scores within the group of treated family members was significantly greater than within family members in the control group. Administering a brief hand massage using pleasant-smelling oils to patients in an intensive care unit may reduce anxiety of family members who administer the treatment. ©2015 American Association of Critical-Care Nurses.

Introduction: During the war circumstances, women and children are exposed to multiple traumatic experiences, one of which is an violent disappearance of a family member. Goal: The aim of this research was to establish the presence of symptoms of depression, anxiety and somatization in women in Bosnia and Herzegovina who have sought their war missing family members for 15 to 18 years. Subjects and Methods: The research was based on a sample of 120 women with war missing family member and 40 women without a war missing family member as a control group. For assessment of depression, anxiety and symptoms of somatization the self-rating Beck Depression Inventory (BDI), Hamilton Anxiety Rating Scale (HAM-A), Somatic Symptoms Index (SSI) questionnaire and a general questionnaire on the sociodemographic data and data on war missing family members were used. Results: A significantly higher intensity of symptoms of depression (p<0.001), anxiety (p<0.001) and somatization (p = 0.013) was present in women with, in comparison to women without a missing family member. In comparison of the kinship with the missing family members, statistically significantly higher intensity of symptoms of depression, anxiety and somatization was in women with a missing child (p<0.001) in comparison to other missing family members. Conclusion: A prolonged period of seeking, waiting and uncertainty of what happened in the war with the missing family member presents for those women a prolonged suffering manifested through depression, anxiety and symptoms of somatization.

Anti-E2, syn-E2, inv-, and ret-S N 2 reaction channels for the gas-phase reaction of F - + CH 3 CH 2 I were characterized with a variety of electronic structure calculations. Geometrical analysis confirmed synchronous E2-type transition states for the elimination of the current reaction, instead of nonconcerted processes through E1cb-like and E1-like mechanisms. Importantly, the controversy concerning the reactant complex for anti-E2 and inv-S N 2 paths has been clarified in the present work. A positive barrier of +19.2 kcal/mol for ret-S N 2 shows the least feasibility to occur at room temperature. Negative activation energies (-16.9, -16.0, and -4.9 kcal/mol, respectively) for inv-S N 2, anti-E2, and syn-E2 indicate that inv-S N 2 and anti-E2 mechanisms significantly prevail over the eclipsed elimination. Varying the leaving group for a series of reactions F - + CH 3 CH 2 Y (Y = F, Cl, Br, and I) leads to monotonically decreasing barriers, which relates to the gradually looser TS structures following the order F > Cl > Br > I. The reactivity of each channel nearly holds unchanged except for the perturbation between anti-E2 and inv-S N 2. RRKM calculation reveals that the reaction of the fluorine ion with ethyl iodide occurs predominately via anti-E2 elimination, and the inv-S N 2 pathway is suppressed, although it is energetically favored. This phenomenon indicates that, in evaluating the competition between E2 and S N 2 processes, the kinetic or dynamical factors may play a significant role. By comparison with benchmark CCSD(T) energies, MP2, CAM-B3LYP, and M06 methods are recommended to perform dynamics simulations of the title reaction.

We have designed new compounds within the homologous series Ae2F2M(1+n)X(3+n) (Ae = Sr, Ba; M = main group metal; n = integer) built up from the stacking of 2D building blocks of rock salt and fluorite types. By incrementally increasing the size of the rock salt 2D building blocks, we have obtained two new n = 1 members of this homologous series, namely, Sr2F2Sb2Se4 and Ba2F2Sb2Se4. We then succeeded in synthesizing these compounds using a high-temperature ceramic method. The structure refinements from the powder or single-crystal X-ray diffraction data confirmed presence of the expected alternating stacking of fluorite [Ae2F2] (Ae = Sr, Ba) and rock salt [Sb2Se4] 2D building blocks. However the Ba derivative shows a strong distortion of the [Sb2Se4] block and a concomitant change of the Sb atom coordination likely related to the lone-pair activity.

to identify the coping strategies of family members of patients with mental disorders and relate them to family member sociodemographic variables and to the patient's clinical variables. this was a descriptive study conducted at a psychiatric hospital in the interior of the state of São Paulo, with 40 family members of hospitalized patients over the age of 18, and who followed the patient before and during hospitalization. We used tools to characterize the subjects and the Folkman and Lazarus Inventory of Coping Strategies. the coping strategies most often used by family members were social support and problem solving. Mothers and fathers used more functional strategies (self-control p=0.037, positive reappraisal p=0.037, and social support p=0,021). We found no significant differences between the strategies and other variables examined. despite the suffering resulting from the illness of a dear one, family members make more use of functional strategies, allowing them to cope with adversities in a more well-adjusted way. identificar as estratégias de enfrentamento de familiares de pacientes com transtornos mentais e relacioná-las com as variáveis sociodemográficas do familiar e clínicas do paciente. estudo descritivo, desenvolvido em hospital psiquiátrico do interior do estado de São Paulo, com 40 familiares de pacientes internados, maiores de 18 anos e que acompanhavam o paciente antes e durante a internação.

2015-01-01

Protein degradation via the multistep ubiquitin/26S proteasome pathway is a rapid way to alter the protein profile and drive cell processes and developmental changes. Many key regulators of embryonic development are targeted for degradation by E3 ubiquitin ligases. The most studied family of E3 ubiquitin ligases is the SCF ubiquitin ligases, which use F-box adaptor proteins to recognize and recruit target proteins. Here, we used a bioinformatics screen and phylogenetic analysis to identify and annotate the family of F-box proteins in the Xenopus tropicalis genome. To shed light on the function of the F-box proteins, we analyzed expression of F-box genes during early stages of Xenopus development. Many F-box genes are broadly expressed with expression domains localized to diverse tissues including brain, spinal cord, eye, neural crest derivatives, somites, kidneys, and heart. All together, our genome-wide identification and expression profiling of the Xenopus F-box family of proteins provide a foundation for future research aimed to identify the precise role of F-box dependent E3 ubiquitin ligases and their targets in the regulatory circuits of development.

In this study of 20 patients in the 13th-17th week of pregnancy abortion was induced with intrauterine, extraamniotic application of prostaglandins (PG) E2 or F2 in gel form. The gel composition was as follows: 4% tylose MH 300, 2% glycerine, 1% chlorhexidine digluconate, 83% sterile distilled water and 10% PG stock solution. Both PGE2 and PGF2 gels were used. Final concentration was 2.5 mg E2 or 2.5 mg F2 per g of gel. Gel was applied via transcervical, extraamniotic polyethylene catheter every 2-3 hours. Results: PGE2-gel was used in 14 cases. After 3-4 applications both fetus and placenta were expelled. Average dose used was 4.6 mg E2/patient. First contractions started in 30 minutes; induction to expulsion time was 11 hours 35 minutes. F2-gel given to 6 patients resulted in expulsion of the fetus in all cases but placenta needed removal by curettage in 4 patients. Average dose per patient was 17.7 mg of F2; first contractions in 30 minutes, average expulsion time 17 hours 38 minutes. With both PGs there were painful contractions which were controlled with a combination of pentazocine and Valium. PGE2 caused vomiting in 5 patients. No increased bleeding or postabortion infection occurred. Follow-up curettage was done in all patients to ensure removal of all tissues. Overall evaluation of the PG-gels was considered good. PG stability in gel form is good; during 8 months of preservation in sterile aluminum tubes at -25 degrees Celsius no decline in clinical effectiveness was noted. The gel application is less expensive than the slow-injection pump method.

The aim of this study was to describe aged home care clients' and their family members' experiences of their family functioning, family health and social support received. An additional purpose was to determine which factors are connected with social support. Increasing life expectancy and ageing of the population require consideration of the adequacy of home care services and the role of family members as care providers. The older population is a very heterogeneous group because of their variable needs and several disabilities. To ensure the quality of home care, experimental information is needed from clients and their family members. A survey design with convenience sampling. The home care client and a family member of his/her answered a questionnaire together, including background questions, the Family Functioning, Health and Social Support instrument and an open question about support received from home care. Statistical methods were used to describe quantitative data, and content analysis was used in analysing the replies to the open question. Family health was noted as good, and family functioning and overall social support fairly good. An older person's higher basic education, higher age of the family member, better family health and male gender were connected with better social support received. The relationship of the older person and the family member as well as the duration of home care service use had an effect on social support received. The content analysis raised expectations related to time, planning of service, organisational factors and caring practise. Home care clients' and families' needs for support vary, and therefore, the assessment of needs, care planning and updating are important. The variable support needs of older people and their family members require flexible and adaptable home services. Cooperation between all participants involved in care would promote the well-being of the older person and the entire family. © 2012 Blackwell

In cancer cells, the retinoblastoma tumor suppressor RB is directly inactivated by mutation in the RB gene or functionally inhibited by abnormal activation of cyclin-dependent kinase activity. While variations in RB levels may also provide an important means of controlling RB function in both normal and cancer cells, little is known about the mechanisms regulating RB transcription. Here we show that members of the RB and E2F families bind directly to the RB promoter. To investigate how the RB/E2F pathway may regulate Rb transcription, we generated reporter mice carrying an eGFP transgene inserted into a bacterial artificial chromosome containing most of the Rb gene. Expression of eGFP largely parallels that of Rb in transgenic embryos and adult mice. Using these reporter mice and mutant alleles for Rb, p107, and p130, we found that RB family members modulate Rb transcription in specific cell populations in vivo and in culture. Interestingly, while Rb is a target of the RB/E2F pathway in mouse and human cells, Rb expression does not strictly correlate with the cell cycle status of these cells. These experiments identify novel regulatory feedback mechanisms within the RB pathway in mammalian cells. PMID:20100864

Family members (FMs) often provide support to patients, regularly attend cancer consultations and are often involved in medical decision-making. Limited research has been conducted to date to understand patients' and FMs' perceptions about family involvement in cancer consultations. Therefore, this study aimed to qualitatively explore the attitudes and experiences of Australian cancer patients and FMs regarding (1) family attendance at consultations, (2) family roles in consultations and (3) the challenges of family involvement. Thirty patients and 33 FMs, recruited through either a tertiary metropolitan oncology clinic or national cancer patient advocacy group, participated in semi-structured interviews. Interviews were transcribed and qualitatively analysed using Framework analysis methods. Four relevant themes were identified: (1) negotiating family involvement, (2) attitudes towards the roles FMs assume, (3) challenges of family involvement and (4) family-clinician interactions. Overall, patients appreciated family involvement and valued FMs' provision of emotional and informational support, and FMs also found benefit from participating in consultations. Some patients appreciated their FM assuming the role of 'messenger' between the consultation and extended family. However, a number of challenges were also reported by patients (e.g. maintaining privacy, mismatched patient-family information needs) and FMs (e.g. emotional toll of supportive roles, negative behaviours of clinicians towards FMs). FMs appear to make valuable contributions to cancer consultations, and their presence can benefit both the patient and the FM themselves in many ways. However, for some FMs, attending consultations can be challenging. Study findings point to the need for psychosocial support addressing FMs' needs and the development of communication strategies for oncology clinicians to positively engage with FMs. Further research is needed in these areas.

To compare the health conditions and health care costs of family members of patients diagnosed with a Major Depressive Disorder (MDD) to family members of patients without an MDD diagnosis. Using electronic health record data, we identified family members (n=201,914) of adult index patients (n=92,399) diagnosed with MDD between 2009 and 2014 and family members (n=187,011) of matched patients without MDD. Diagnoses, health care utilization and costs were extracted for each family member. Logistic regression and multivariate models were used to compare diagnosed health conditions, health services cost, and utilization of MDD and non-MDD family members. Analyses covered the 5years before and after the index patient's MDD diagnosis. MDD family members were more likely than non-MDD family members to be diagnosed with mood disorders, anxiety, substance use disorder, and numerous other conditions. MDD family members had higher health care costs than non-MDD family members in every period analyzed, with the highest difference being in the year before the index patient's MDD diagnosis. Family members of patients with MDD are more likely to have a number of health conditions compared to non-MDD family members, and to have higher health care cost and utilization. Copyright © 2017.

This article presents emerging findings from the first year of a two-year study, which employed ethnographic methods to explore the culture of interprofessional collaboration (IPC) and family member involvement in eight North American intensive care units (ICUs). The study utilized a comparative ethnographic approach - gathering observation, interview and documentary data relating to the behaviors and attitudes of healthcare providers and family members across several sites. In total, 504 hours of ICU-based observational data were gathered over a 12-month period in four ICUs based in two US cities. In addition, 56 semi-structured interviews were undertaken with a range of ICU staff (e.g. nurses, doctors and pharmacists) and family members. Documentary data (e.g. clinical guidelines and unit policies) were also collected to help develop an insight into how the different sites engaged organizationally with IPC and family member involvement. Directed content analysis enabled the identification and categorization of major themes within the data. An interprofessional conceptual framework was utilized to help frame the coding for the analysis. The preliminary findings presented in this paper illuminate a number of issues related to the nature of IPC and family member involvement within an ICU context. These findings are discussed in relation to the wider interprofessional and health services literature.

Temperature sensing in Yersinia pestis: regulation of yopE transcription by lcrF.

PubMed Central

Hoe, N P; Minion, F C; Goguen, J D

1992-01-01

In Escherichia coli, a yopE::lacZ fusion was found to be regulated by temperature in the presence of the cloned BamHI G fragment of Yersinia pestis plasmid pCD1, which contains the lcrF locus. Increasing the copy number of lcrF relative to that of the yopE reporter had a negligible effect on the induction ratio (26 versus 37 degrees C) but caused large reductions in the absolute levels of yopE transcription. We localized the lcrF gene by monitoring the induction phenotype of BamHI G deletion derivatives. Sequencing revealed an open reading frame capable of encoding a protein of 30.8 kDa. A protein product of this size was detected in a T7 expression system, and LcrF-dependent yopE-specific DNA binding activity was observed. As expected, LcrF exhibited 98% homology to VirF of Yersinia enterocolitica and significant homology to the carboxy termini of other members of the AraC family of transcriptional regulatory proteins. These proteins could be divided into two classes according to function: those regulating operons involved in catabolism of carbon and energy sources and those involved in regulating virulence genes. lcrF::lacZ transcriptional fusions were constructed and analyzed in Y. pestis and E. coli. The activity of the fusions was not affected by the native pCD1 virulence plasmid, an intact lcrF gene, or temperature. Thus, induction of lcrF transcription is not essential for temperature-dependent activation of yopE transcription. A portion of LcrF was found associated with the membrane fraction in E. coli; however, pulse-chase experiments indicated that this result is an artifact of fractionation. Images PMID:1624422

The family has a primary role in caring for family members who are suicidal and in the prevention of future suicide. However, the impact that suicidal behaviour has on these family members is poorly understood. To explore the lived experiences of participants who cared for suicidal family members. Eighteen participants were interviewed using a short topic guide. Responses were digitally recorded and transcripts were analysed using thematic analysis. One overarching theme: "Hard work for the whole family" and four sub-themes: (i) Family burden, (ii) competing pressures, (iii) secrecy and shame and (iv) helplessness and guilt. Caring for a suicidal family member may be euphemistically summarised as "hard work" that impacts heavily on the day-to-day tasks of other family members. Participants spent much time worrying and ruminating about the risk of suicide in their family member. Mental health care professionals ought to acknowledge and address the impact that suicidal behaviour has on family carers.

Even though more than 25% of Americans die in nursing homes, end-of-life care has consistently been found to be less than adequate in this setting. Even for those residents on hospice, end-of-life care has been found to be problematic. This study had 2 research questions; (1) How do family members of hospice nursing home residents differ in their anxiety, depression, quality of life, social networks, perceptions of pain medication, and health compared with family members of community dwelling hospice patients? (2) What are family members' perceptions of and experiences with end-of-life care in the nursing home setting? This study is a secondary mixed methods analysis of interviews with family members of hospice nursing home residents and a comparative statistical analysis of standard outcome measures between family members of hospice patients in the nursing home and family members of hospice patients residing in the community. Outcome measures for family members of nursing home residents were compared (n = 176) with family members of community-dwelling hospice patients (n = 267). The family members of nursing home residents reported higher quality of life; however, levels of anxiety, depression, perceptions of pain medicine, and health were similar for hospice family members in the nursing home and in the community. Lending an understanding to the stress for hospice family members of nursing home residents, concerns were found with collaboration between the nursing home and the hospice, nursing home care that did not meet family expectations, communication problems, and resident care concerns including pain management. Some family members reported positive end-of-life care experiences in the nursing home setting. These interviews identify a multitude of barriers to quality end-of-life care in the nursing home setting, and demonstrate that support for family members is an essential part of quality end-of-life care for residents.

Transcription factor E2F-2 is a regulator of cell cycle. Researchers identified E2F-2 genes from yeasts to humans, but few reports investigated E2F-2 gene from black tiger shrimp. In the present study, we cloned E2F-2 gene from black tiger shrimp (Penaeus monodon). Full-length PmE2F-2 complementary DNA sequence measures 3,189 bp with an open reading frame of 1,371 bp. Complete PmE2F-2 genomic sequence (17,305 bp) of P. monodon contains nine exons, which are separated by eight introns. Quantitative real-time polymerase chain reaction (qRT-PCR) analysis indicated that PmE2F-2 is highly expressed in hepatopancreas and ovaries of P. monodon. Highest PmE2F-2 expression levels were observed in stage III ovarian development of P. monodon. PmE2F-2 expression levels were significantly augmented in ovaries of P. monodon after 5-hydroxytryptamine injection and eyestalk ablation. RNA interference experiments were conducted to examine PmE2F-2, PmCDK2, and PmCyclin E expression profiles. PmE2F-2 was successfully knocked down in ovaries and hepatopancreas via double-stranded RNA (dsRNA)–E2F-2 injection. In the same organs, PmE2F-2 expression localization and level were investigated through in situ hybridization, which revealed consistent results with those of qRT-PCR. After dsRNA—E2F-2 injection, gonadosomatic index of shrimp was significantly lower than those following dsRNA—GFP and phosphate-buffered solution injections. Therefore, PmE2F-2 may be involved in ovarian maturation in P. monodon. PMID:28558060

CDH1 regulates E2F1 degradation in response to differentiation signals in keratinocytes

The E2F1 transcription factor plays key roles in skin homeostasis. In the epidermis, E2F1 expression is essential for normal proliferation of undifferentiated keratinocytes, regeneration after injury and DNA repair following UV radiation-induced photodamage. Abnormal E2F1 expression promotes nonmelanoma skin carcinoma. In addition, E2F1 must be downregulated for proper keratinocyte differentiation, but the relevant mechanisms involved remain poorly understood. We show that differentiation signals induce a series of post-translational modifications in E2F1 that are jointly required for its downregulation. Analysis of the structural determinants that govern these processes revealed a central role for S403 and T433. In particular, substitution of these two amino acid residues with non-phosphorylatable alanine (E2F1 ST/A) interferes with E2F1 nuclear export, K11- and K48-linked polyubiquitylation and degradation in differentiated keratinocytes. In contrast, replacement of S403 and T433 with phosphomimetic aspartic acid to generate a pseudophosphorylated E2F1 mutant protein (E2F1 ST/D) generates a protein that is regulated in a manner indistinguishable from that of wild type E2F1. Cdh1 is an activating cofactor that interacts with the anaphase-promoting complex/cyclosome (APC/C) ubiquitin E3 ligase, promoting proteasomal degradation of various substrates. We found that Cdh1 associates with E2F1 in keratinocytes. Inhibition or RNAi-mediated silencing of Cdh1 prevents E2F1 degradation in response to differentiation signals. Our results reveal novel regulatory mechanisms that jointly modulate post-translational modifications and downregulation of E2F1, which are necessary for proper epidermal keratinocyte differentiation.

Studies were performed to determine how frequently acute infections with Toxoplasma gondii occur among family members of patients with acute acquired lymphadenopathic toxoplasmosis. In five of the nine families studied, more than one family member had serologic evidence of recent acute infection with T gondii. In three of the families, the immunoglobulin M and immunoglobulin G antibody titers to T gondii among infected family members were similar irrespective of whether lymphadenopathy was present. Lymphadenopathy developed in one family member in each of two families (families VIII and IX) three and eight months after lymphadenopathy had developed in the index case (proband). These results suggest that common-source outbreaks occur with surprising frequency among family members of patients with lymphadenopathic toxoplasmosis and that the humoral response is similar with different manifestations of the infection.

The B-subunits of replicative DNA polymerases from Archaea to humans belong to the same protein family, suggesting that they share a common fundamental function. We report here the gene structure for the B-subunit of human DNA polymerase ɛ (POLE2), whose expression and transcriptional regulation is typical for replication proteins with some unique features. The 75 bp core promoter region, located within exon 1, contains an Sp1 element that is a critical determinant of promoter activity as shown by the luciferase reporter, electrophoretic mobility shift and DNase I footprinting assays. Two overlapping E2F elements adjacent to the Sp1 element are essential for full promoter activity and serum response. Binding sites for E2F1 and NF-1 reside immediately downstream from the core promoter region. Our results suggest that human POLE2 is regulated by two E2F–pocket protein complexes, one associated with Sp1 and the other with NF-1. So far, only one replicative DNA polymerase B-subunit gene promoter, POLA2 encoding the B-subunit of DNA polymerase α, has been characterized. Mitogenic activation of the POLE2 promoter by an E2F-mediated mechanism resembles that of POLA2, but the regulation of basal promoter activity is different between these two genes. PMID:11433027

Although family members of patients with aortic dissection (AoD) are believed to be at higher risk of AoD, the prognostic value of family history (FH) of aortic dissection (FHAD) in family members of patients with AoD has not been studied rigorously. We seek examine how much a positive FHAD increases the risk of developing new aortic dissection (AoD) among first-degree relatives. Patients with AoD at our institution were analyzed for information of FHAD. Positive FHAD referred to that AoD occurred in index patient and one or more first-degree relatives. Negative FHAD was defined as the condition in which only one case of AoD (the index patient) occurred in the family. The age at AoD, exposure years in adulthood before AoD, and annual probability of AoD among first-degree relatives were compared between patients with negative and positive FHADs. FHAD was positive in 32 and negative in 68 among the 100 AoD patients with detailed family history information. Mean age at dissection was 59.9±14.7years. Compared to negative FHAD, patients with positive FHAD dissected at significantly younger age (54.7±16.8 vs 62.4±13.0years, p=0.013), had more AoD events in first-degree relatives (2.3±0.6 vs 1.0±0.0, p<0.001), and shorter exposure years per AoD event (18.3±6.7 vs 43.1±8.5, p<0.001). Annual probability of AoD per first-degree relative was 2.77 times higher in patients with positive than negative FHADs (0.0100±0.0057 vs 0.0036±0.0014, p<0.001). A positive FHAD confers a significantly increased risk of developing aortic dissection on family members, with a higher annual probability of aortic dissection, a shorter duration of "exposure time" before dissection occurs and a lower mean age at time of dissection.

The purpose of this study was to evaluate the effective dose to family members of thyroid cancer and hyperthyroid patients treated with radioiodine-131, and also to compare the results with dose constraints proposed by the International Commission of Radiological Protection (ICRP) and the Basic Safety Standards (BSS) of the International Atomic Energy Agency (IAEA). For the estimation of the effective doses, sixty family members of sixty patients, treated with radioiodine-131, and thermoluminiscent dosimeters (Model TLD 100) were used. Thyroid cancer patients were hospitalized for three days, while hyperthyroid patients were treated on out-patient basis. The family members wore TLD in front of the torso for seven days. The radiation doses to family members of thyroid cancer patients were well below the recommended dose constraint of 1 mSv. The mean value of effective dose was 0.21 mSv (min 0.02 - max 0.51 mSv). Effective doses, higher than 1 mSv, were detected for 11 family members of hyperthyroid patients. The mean value of effective dose of family members of hyperthyroid patients was 0.87 mSv (min 0.12 - max 6.79). The estimated effective doses to family members of hyperthyroid patients were higher than the effective doses to family members of thyroid carcinoma patients. These findings may be considered when establishing new national guidelines concerning radiation protection and release of patients after a treatment with radioiodine therapy.

Hispanics show poorer self-management of type 2 diabetes than non-Hispanic whites. Although previous studies have reported socioeconomic and cultural barriers to diabetes self-management by Hispanics, little is known about perceived barriers to diabetes self-management from the perspectives of both Hispanics and their family members. The purpose of the study was to explore perceived barriers among Hispanic immigrants with diabetes and their family members. A qualitative study using 5 focus groups was conducted. A total of 73 Hispanic immigrants with type 2 diabetes (n = 36) and family members (n = 37) were recruited in the southeastern United States for a family-based intervention study of diabetes-self management. Participants were asked to describe their perceptions of barriers to self-management. The 5 sessions were audiotaped and transcribed, translated from Spanish into English, and analyzed using standard content analysis. Demographics, hemoglobin A1C levels, blood pressure, and body mass index (BMI) were obtained both for participants with diabetes and for their family members. Barriers to diabetes self-management identified by participants with diabetes were in 3 major themes categorized as: suffering from diabetes, difficulties in managing the disease, and lack of resources/support. Two key themes emerged pertaining to family members: we can provide support and we lack knowledge. Perceived barriers to diabetes self-management described by Hispanic immigrants with diabetes and family members indicate a lack of intervention strategies to meet their needs. Interventions should include culturally relevant resources, family support, and diabetes self-management skills education.

Increasing family members' appreciation of family caregiving stress.

Participants read a message discussing the duties of a typical family caregiver (for example, a woman taking care of her elderly mother) and the associated psychological, physical, social, and financial stresses. The message was accompanied by an appeal that was either a control or was altruistic (other-oriented: focusing on the mother/caregiver's well-being) or egoistic (self-oriented: focusing on the child of the caregiver's needs and feelings). Participants who received an altruistic appeal were more appreciative of caregiving stresses than were those given an egoistic or a control appeal. Increasing family members' awareness of the stress involved in family caregiving is a first step in encouraging them to personally intervene on behalf of the caregiver.

E2F1 transcription factor and its impact on growth factor and cytokine signaling.

E2F1 is a transcription factor involved in cell cycle regulation and apoptosis. The transactivation capacity of E2F1 is regulated by pRb. In its hypophosphorylated form, pRb binds and inactivates DNA binding and transactivating functions of E2F1. The growth factor stimulation of cells leads to activation of CDKs (cyclin dependent kinases), which in turn phosphorylate Rb and hyperphosphorylated Rb is released from E2F1 or E2F1/DP complex, and free E2F1 can induce transcription of several genes involved in cell cycle entry, induction or inhibition of apoptosis. Thus, growth factors and cytokines generally utilize E2F1 to direct cells to either fate. Furthermore, E2F1 regulates expressions of various cytokines and growth factor receptors, establishing positive or negative feedback mechanisms. This review focuses on the relationship between E2F1 transcription factor and cytokines (IL-1, IL-2, IL-3, IL-6, TGF-beta, G-CSF, LIF), growth factors (EGF, KGF, VEGF, IGF, FGF, PDGF, HGF, NGF), and interferons (IFN-α, IFN-β and IFN-γ).

Background This article explores the association of people who inject drugs and their family members in terms of mental health and family relations. The objective was to understand the family context and its impact on people who inject drugs in a family-oriented culture in Vietnam. Methods Cross-sectional assessment data were gathered from 83 people who inject drugs and 83 of their family members recruited from four communes in Phú Thọ province, Vietnam. Depressive symptoms and family relations were measured for both people who inject drugs and family members. Internalized shame and drug-using behavior were reported by people who inject drugs, and caregiver burden was reported by family members. Results We found that higher level of drug using behavior of people who inject drugs was significantly associated with higher depressive symptoms and lower family relations reported by themselves as well as their family members. Family relations reported by people who inject drugs and their family members were positively correlated. Conclusion The findings highlight the need for interventions that address psychological distress and the related challenges faced by family members of people who inject drugs. The article has policy implication which concludes with an argument for developing strategies that enhance the role of families in supporting behavioral change of people who inject drugs.

The heterodimeric assembly of the CD94-NKG2 receptor family and implications for human leukocyte antigen-E recognition.

The CD94-NKG2 receptor family that regulates NK and T cells is unique among the lectin-like receptors encoded within the natural killer cell complex. The function of the CD94-NKG2 receptors is dictated by the pairing of the invariant CD94 polypeptide with specific NKG2 isoforms to form a family of functionally distinct heterodimeric receptors. However, the structural basis for this selective pairing and how they interact with their ligand, HLA-E, is unknown. We describe the 2.5 A resolution crystal structure of CD94-NKG2A in which the mode of dimerization contrasts with that of other homodimeric NK receptors. Despite structural homology between the CD94 and NKG2A subunits, the dimer interface is asymmetric, thereby providing a structural basis for the preferred heterodimeric assembly. Structure-based sequence comparisons of other CD94-NKG2 family members, combined with extensive mutagenesis studies on HLA-E and CD94-NKG2A, allows a model of the interaction between CD94-NKG2A and HLA-E to be established, in which the invariant CD94 chain plays a more dominant role in interacting with HLA-E in comparison to the variable NKG2 chain.

Cushing's syndrome is caused by excessive adrenocorticotropic hormone (ACTH) secretion derived from pituitary corticotroph tumors (Cushing disease) or from non-pituitary tumors (ectopic Cushing's syndrome). Hypercortisolemic features of ectopic Cushing's syndrome are severe, and no definitive treatment for paraneoplastic ACTH excess is available. We aimed to identify subcellular therapeutic targets by elucidating transcriptional regulation of the human ACTH precursor POMC (proopiomelanocortin) and ACTH production in non-pituitary tumor cells and in cell lines derived from patients with ectopic Cushing's syndrome. We show that ectopic hPOMC transcription proceeds independently of pituitary-specific Tpit/Pitx1 and demonstrate a novel E2F1-mediated transcriptional mechanism regulating hPOMC We identify an E2F1 cluster binding to the proximal hPOMC promoter region (-42 to +68), with DNA-binding activity determined by the phosphorylation at Ser-337. hPOMC mRNA expression in cancer cells was upregulated (up to 40-fold) by the co-expression of E2F1 and its heterodimer partner DP1. Direct and indirect inhibitors of E2F1 activity suppressed hPOMC gene expression and ACTH by modifying E2F1 DNA-binding activity in ectopic Cushing's cell lines and primary tumor cells, and also suppressed paraneoplastic ACTH and cortisol levels in xenografted mice. E2F1-mediated hPOMC transcription is a potential target for suppressing ACTH production in ectopic Cushing's syndrome. © 2016 Society for Endocrinology.

We examined (a) the demographic and clinical correlates of worries about hypoglycemia in adult family members of adults with diabetes, and (b) the association of these worries with measures of diabetes support. The second multinational Diabetes Attitudes, Wishes and Needs (DAWN2) study cross-sectionally surveyed 2057 family members from 17 countries. Participants completed questions about demographics, diabetes, and psychosocial functioning, including worry about overall and nocturnal hypoglycemia. Analyses included hierarchical ordinal and linear regression. Eighty-five percent of family members (n=1661) were at least occasionally very worried about the risk of hypoglycemic events overall. Correlates of worries about hypoglycemia included female gender, higher age and lower education in the family member, younger age of the person with diabetes and this person being a parent or another adult (versus spouse or partner), insulin or non-insulin injectable treatment, severe or non-severe hypoglycemia in the past 12months, and family member recognition of hypoglycemia. Elevated worries about hypoglycemia had a significant independent association with increased odds of diabetes-related family arguments and family member frustration in providing helpful support (OR range 1.60-3.72). High levels of worries about hypoglycemia were associated with increased odds of attending diabetes-related health-care visits. Worries about hypoglycemia were not associated with family member involvement in diabetes care. Similar results were found for worries about nocturnal events. Worries about hypoglycemia were common in family members and were associated with suboptimal diabetes support. This issue therefore deserves increased clinician attention.

The aim of the study was to reach a more profound understanding, through looking at nurses' working situation, of those factors that influence how nurses are able to work together with family members of older people living in nursing homes or similar facilities. Working with the care of older people as a Registered Nurse provides a varied job with many challenges. Nurses have to co-operate with family members of those in community health care. Co-operation is important and necessary for all involved. Nurses working in elder care in a geographically defined area received a questionnaire with three open-ended questions, on the difficulties and/or problems involved with working together with family members, and the positive or negative aspects of this co-operation. Analysis was carried out using the latent content analysis method. Three themes, problems within the system, interaction with families and caring in nursing work, are presented with categories and their subcategories. The nurses wanted their superior to be a nurse so that their working situation would be better understood. Appreciation from their superior and family members was also a very important part of their work as nurses in community health care. The frequent changes and the lack of time in the work of elder care often put nurses under considerable psychological pressure. For the most part family members are a resource for the elder, but sometimes they will avoid contact, which will make co-operating difficult. Registered Nurses and family members are dependent on each other in their care of the elder. Relevance to clinical practice. More attention should be paid to the working situation of Registered Nurses in community health care, and their ability to work together with family members of older people.

To investigate how family members' attitudes toward functional regain, and patients' knowledge and intention of independence influence poststroke rehabilitation. Cross-sectional study. Three rehabilitation inpatient settings. Younger (n=79) and older (n=84) poststroke patients, along with their family members (spouses, n=104; children, n=59). Not applicable. Custom-designed questionnaires were used to tap into the patients' knowledge about rehabilitation (Patient's Rehabilitation Questionnaire-Knowledge About Rehabilitation) and intention of independence (Patient's Rehabilitation Questionnaire-Intention of Independence), and family members' attitudes toward patients in performing basic activities of daily living (BADL) (Family Member Attitudes Questionnaire-BADL) and instrumental activities of daily living (Family Member Attitudes Questionnaire-instrumental activities of daily living). The rehabilitation outcomes included gains in motor, cognitive, and emotional functions, and self-care independence, measured with common clinical instruments. The Family Member Attitudes Questionnaire-BADL predicted cognitive outcome and the Patient's Rehabilitation Questionnaire-Intention of Independence predicted motor outcome for both groups. Differential age-related effects were revealed for the Patient's Rehabilitation Questionnaire-Intention of Independence in predicting emotional outcome only for the younger group, and self-care independence only for the older group. Patients' intention of independence positively affected motor recovery, while family members' positive attitudes promoted cognitive regain. The findings suggested plausible age-related differences in how patients' intentions affect emotion versus self-care independence outcomes. Future studies should explore strategies for promoting positive attitudes toward independence among patients and family members during poststroke rehabilitation.

Haumea is one of the most interesting and intriguing trans-Neptunian objects (TNOs). It is a large, bright, fast rotator, and its spectrum indicates nearly pure water ice on the surface. It has at least two satellites and a dynamically related family of more than 10 TNOs with very similar proper orbital parameters and similar surface properties. The Haumean family is the only one currently known in the trans-Neptunian belt. Various models have been proposed, but the formation of the family remains poorly understood. In this work, we have investigated the rotational properties of the family members and unconfirmed family candidates with short-term variability studies, and report the most complete review to date. We present results based on five years of observations and report the short-term variability of five family members, and seven candidates. The mean rotational periods, from Maxwellian fits to the frequency distributions, are 6.27 +/- 1.19 hr for the confirmed family members, 6.44 +/- 1.16 hr for the candidates, and 7.65 +/- 0.54 hr for other TNOs (without relation to the family). According to our study, there is a possibility that Haumea family members rotate faster than other TNOs, however, the sample of family member is still too limited for a secure conclusion. We also highlight the fast rotation of 2002 GH(sub 32). This object has a 0.36 +/- 0.02 mag amplitude lightcurve and a rotational period of about 3.98 hr. Assuming 2002 GH(sub 32) is a triaxial object in hydrostatic equilibrium, we derive a lower limit to the density of 2.56 g cm(exp -3). This density is similar to Haumea's and much more dense than other small TNO densities.

An important component of barley cell walls, particularly in the endosperm, is (1,3;1,4)-β- glucan, a polymer that has proven health benefits in humans and that influences processability in the brewing industry. Genes of the cellulose synthase-like (Csl) F gene family have been shown to be involved in (1,3;1,4)-β-glucan synthesis but many aspects of the biosynthesis are still unclear. Examination of the sequence assembly of the barley genome has revealed the presence of an additional three HvCslF genes (HvCslF11, HvCslF12 and HvCslF13) which may be involved in (1,3;1,4)-β-glucan synthesis. Transcripts of HvCslF11 and HvCslF12 mRNA were found in roots and young leaves, respectively. Transient expression of these genes in Nicotiana benthamiana resulted in phenotypic changes in the infiltrated leaves, although no authentic (1,3;1,4)-β-glucan was detected. Comparisons of the CslF gene families in cereals revealed evidence of intergenic recombination, gene duplications and translocation events. This significant divergence within the gene family might be related to multiple functions of (1,3;1,4)-β-glucans in the Poaceae. Emerging genomic and global expression data for barley and other cereals is a powerful resource for characterising the evolution and dynamics of complete gene families. In the case of the CslF gene family, the results will contribute to a more thorough understanding of carbohydrate metabolism in grass cell walls. PMID:24595438

The hadronic part of the electron structure function F2e has been measured for the first time, using e+e- data collected by the DELPHI experiment at LEP, at centre-of-mass energies of √{ s} = 91.2- 209.5 GeV. The data analysis is simpler than that of the measurement of the photon structure function. The electron structure function F2e data are compared to predictions of phenomenological models based on the photon structure function. It is shown that the contribution of large target photon virtualities is significant. The data presented can serve as a cross-check of the photon structure function F2γ analyses and help in refining existing parameterisations.

Fang, Zejun; Gong, Chaoju; Liu, Hong

2015-08-21

As the ribonucleotide reductase small subunit, the high expression of ribonucleotide reductase small subunit M2 (RRM2) induces cancer and contributes to tumor growth and invasion. In several colorectal cancer (CRC) cell lines, we found that the expression levels of RRM2 were closely related to the transcription factor E2F1. Mechanistic studies were conducted to determine the molecular basis. Ectopic overexpression of E2F1 promoted RRM2 transactivation while knockdown of E2F1 reduced the levels of RRM2 mRNA and protein. To further investigate the roles of RRM2 which was activated by E2F1 in CRC, CCK-8 assay and EdU incorporation assay were performed. Overexpression ofmore » E2F1 promoted cell proliferation in CRC cells, which was blocked by RRM2 knockdown attenuation. In the migration and invasion tests, overexpression of E2F1 enhanced the migration and invasion of CRC cells which was abrogated by silencing RRM2. Besides, overexpression of RRM2 reversed the effects of E2F1 knockdown partially in CRC cells. Examination of clinical CRC specimens demonstrated that both RRM2 and E2F1 were elevated in most cancer tissues compared to the paired normal tissues. Further analysis showed that the protein expression levels of E2F1 and RRM2 were parallel with each other and positively correlated with lymph node metastasis (LNM), TNM stage and distant metastasis. Consistently, the patients with low E2F1 and RRM2 levels have a better prognosis than those with high levels. Therefore, we suggest that E2F1 can promote CRC proliferation, migration, invasion and metastasis by regulating RRM2 transactivation. Understanding the role of E2F1 in activating RRM2 transcription will help to explain the relationship between E2F1 and RRM2 in CRC and provide a novel predictive marker for diagnosis and prognosis of the disease. - Highlights: • E2F1 promotes RRM2 transactivation in CRC cells. • E2F1 promotes the proliferation of CRC cells by activating RRM2. • E2F1 promotes the migration

The dying child and surviving family members.

This overview of death and dying focuses on the dying child and surviving family members. Children's concepts of death at different developmental stages are reviewed. These range from an inability to distinguish death from other forms of separation prior to age 3, through partial concepts of death until, by age 10 to 15 years, children are able to conceptualize death as universal, inevitable and final. The importance of adults assisting in the child's growing comprehension of death is stressed. The stages of grief and mourning, as outlined by Kubler-Ross, are reviewed from the perspective of the child and family: denial, anger, bargaining, depression and acceptance. Recognition is given to the variations in coping styles among different family members. The special circumstances related to the death of an infant and the impact of the death of a child on the surviving siblings are discussed. Specific helpful interventions to assist families in coping with mourning are described. The death of a child remains one of the most painful and difficult events for a family and its physician to accept.

Repression of transcriptional activity of C/EBPalpha by E2F-dimerization partner complexes.

PubMed

Zaragoza, Katrin; Bégay, Valérie; Schuetz, Anja; Heinemann, Udo; Leutz, Achim

2010-05-01

The transcription factor CCAAT/enhancer-binding protein alpha (C/EBPalpha) coordinates proliferation arrest and the differentiation of myeloid progenitors, adipocytes, hepatocytes, keratinocytes, and cells of the lung and placenta. C/EBPalpha transactivates lineage-specific differentiation genes and inhibits proliferation by repressing E2F-regulated genes. The myeloproliferative C/EBPalpha BRM2 mutant serves as a paradigm for recurrent human C-terminal bZIP C/EBPalpha mutations that are involved in acute myeloid leukemogenesis. BRM2 fails to repress E2F and to induce adipogenesis and granulopoiesis. The data presented here show that, independently of pocket proteins, C/EBPalpha interacts with the dimerization partner (DP) of E2F and that C/EBPalpha-E2F/DP interaction prevents both binding of C/EBPalpha to its cognate sites on DNA and transactivation of C/EBP target genes. The BRM2 mutant, in addition, exhibits enhanced interaction with E2F-DP and reduced affinity toward DNA and yet retains transactivation potential and differentiation competence that becomes exposed when E2F/DP levels are low. Our data suggest a tripartite balance between C/EBPalpha, E2F/DP, and pocket proteins in the control of proliferation, differentiation, and tumorigenesis.

Geraniol, an acyclic dietary monoterpene, has been found to suppress cancer survival and growth. However, the molecular mechanism underlying the antitumor action of geraniol has not been investigated at the genome-wide level. In this study, we analyzed the microarray data obtained from geraniol-treated prostate cancer cells. Geraniol potently altered a gene expression profile and primarily down-regulated cell cycle-related gene signatures, compared to linalool, another structurally similar monoterpene that induces no apparent phenotypic changes. Master regulator analysis using the prostate cancer-specific regulatory interactome identified that the transcription factor E2F8 as a specific target molecule regulates geraniol-specific cell cycle signatures. Subsequent experiments confirmed that geraniol down-regulated E2F8 expression and the knockdown of E2F8 was sufficient to suppress cell growth by inducing G 2 /M arrest. Epidemiological analysis showed that E2F8 is up-regulated in metastatic prostate cancer and associated with poor prognosis. These results indicate that E2F8 is a crucial transcription regulator controlling cell cycle and survival in prostate cancer cells. Therefore, our study provides insight into the role of E2F8 in prostate cancer biology and therapeutics. © 2016 The Authors. Cancer Medicine published by John Wiley & Sons Ltd.

Oliveira, Carla Roma; Mendes, Álvaro; Sousa, Liliana

2017-06-12

Citizens are now partners in the formal health promotion system. In the management of hereditary diseases, the role of family members is a vital source of support. Elders play a crucial role due to their long relationship with the disease and with patients in the family. However, this role has still been insufficiently explored, particularly in genetic disorders like paramyloidosis. This exploratory qualitative study analyzes the role of elders in families with paramyloidosis, in health promotion for younger members. The critical incidents technique was applied using a semi-structured interview. The study involved 18 participants who reported 76 critical incidents. The interviews were taped and submitted to content analysis. The principal results suggest the following roles for elders with younger family members: act as role models (in behaviors), encourage, inform, and support. The older generations can be mobilized by health professionals as partners to support younger generations in families with paramyloidosis.

The aim of this study was to characterize certain prostaglandin family members in the bovine corpus luteum (CL) during the oestrous cycle and pregnancy. The CL tissue was assigned to the following stages of the oestrous cycle: 1-2, 3-4, 5-7, 8-12, 13-16, >18 days (after regression) and of pregnancy: 1-2, 3-4, 6-7 and >8 months. In these samples, we investigated prostaglandin F2alpha (PTGF), prostaglandin E2 (PTGE) and their receptors (PTGFR, PTGER2, PTGER4), cyclooxygenase 2 (COX-2), PTGF synthase (PTGFS) and PTGE synthase (PTGES). The expression of mRNA was measured by RT-qPCR, hormones by EIA and localization by immunohistochemistry. The mRNA expression of COX-2, PTGFS and PTGES in CL during the early luteal phase was high followed by a continuous and significant downregulation afterwards, as well as during all phases of pregnancy. The concentration of PTGF in CL tissue was high during the early luteal phase, decreased significantly in the mid-luteal phase, and increased again afterwards. In contrast, the concentration of PTGE increased significantly during late luteal phase followed by a decrease during regression. The PTGE level increased again during late pregnancy. Immunohistochemically, the large granulose-luteal cells show strong staining for COX-2 and PTGES during the early luteal stage followed by lower activity afterwards. During pregnancy, most of the luteal cells were only weakly positive or negative. In conclusion, our results indicate that the examined prostaglandin family members are involved in the local mechanisms that regulate luteal function, specifically during CL formation, function and regression and during pregnancy in the cow.

This study examines the influence of race on perceived similarity and conflict between nursing home staff and family members of residents. Despite evidence that the caregiving experience varies by race for both family and professional caregivers, little is known about how race plays a role in staff conflict with residents' family members. We used a representative sample of Certified Nursing Assistants (CNAs) to test relationships between race, treatment from family members, similarity to family members in expectations for care by CNAs, and conflicts with family members concerning aspects of resident care. Results of structural equation modeling indicated that race was not a predictor of staff perception of conflict with family members or of poor treatment from residents' families. However, Black nursing assistants were more likely to perceive that their own expectations of nursing care are dissimilar from those of residents' family members. Dissimilarity predicted reports of poor treatment from family members, and poor treatment was a positive predictor of perception of conflict. The personal long-term nature of nursing home care necessitates a high level of connectedness between family caregivers and nursing home staff. Results highlight the importance of establishing organizational pathways for communication of expectations between nursing staff and residents' families.

INTRODUCTIONS AND AIMS: Research from western countries indicates that family members of addiction patients report heightened stress and psychological morbidity. This current study aimed to examine stress, coping behaviours, related morbidity and subsequent resource utilisation among family members of patients attending a national treatment program in Singapore. The study used a matched case-control design. One hundred family members of addiction patients attending treatment and 100 matched controls completed a semi-structured interview with a researcher. This included the Beck Depression Inventory-II, Short-Form Health Survey-36, General Health Questionnaire-28, Perceived Stress Scale, Family Member Impact Scale and Coping Questionnaire, and also assessed service utilisation. T-tests revealed significantly greater depression, stress and psychiatric morbidity and poorer overall well-being (Short-Form Health Survey-36) among family members compared with controls. Despite the apparent negative impact on mental health, their physical morbidity did not differ from controls and services utilisation was low. Tolerant-inactive coping was found to be most strongly correlated with psychological well-being. Multivariate analysis indicated that perceived stress was the strongest predictor of overall strain (General Health Questionnaire), but this was not moderated by coping style. Subjective appraisal of stress and coping responses are essential factors affecting the morbidity of family members. Family members demonstrated a need and willingness to engage in formal treatment/counselling for their own problems that were attributed to living with an addiction patient. This provides an opportunity for stress management and brief interventions to modify coping styles, thereby minimizing the potential negative mental health impact on family members. © 2011 Australasian Professional Society on Alcohol and other Drugs.

To investigate the levels of internal and external shame among family members of critically ill patients. This prospective study was conducted in 2012/2013 on family members of Intensive Care Unit patients using the Others As Shamer Scale and the Experiential Shame Scale questionnaires. Greek university hospital. Two hundred and twenty-three family members mean-aged (41.5±11.9) were studied, corresponding to 147 ICU patients. Out of these 223, 81 (36.3%) were men and 142 (63.7%) were women, while 79 (35.4%) lived with the patient. Family members who lived with the patient experienced higher internal and external shame compared to those who did not live with the patient (p=0.046 and p=0.028 respectively). Elementary and Junior High School graduates scored significantly higher than the other grades graduates in total Others As Shamer Scale, inferiority and emptiness scale (p<0.001). Intensive Care Unit patients' family members are prone to shame feelings, especially when being of low educational level. Health professionals have to take into consideration the possible implications for the patients and their care. Copyright © 2017 Elsevier Ltd. All rights reserved.

To clarify the verbal communication of feelings between families and patients in Japanese palliative care units from the perspective of bereaved family members by examining (1) proportions of families' and patients' verbalization of six feelings (gratitude, love, seeking forgiveness, giving forgiveness, wishes after death, and continuing bonds), (2) recognition of receiving these feelings through verbalization from the family's perspective, and (3) the specific attitudes of family members that influence their verbalizations. In 2010, a cross-sectional survey was conducted with 968 bereaved families of cancer patients in palliative care units across Japan. Five hundred thirty-seven responses were analyzed. (1) "Gratitude" was verbalized most often (families: 47%; patients: 61%), and "expressing forgiveness" least often (families: 16%; patients: 11%). (2) Even if the words were not used, 81.2% to 88.2% of families answered that they had received the patient's feelings, and 71.8% to 85.4% of families felt the patient had received their feelings. (3) Multiple logistic regression analyses indicated that the strongest attitudes determining verbalizing were "not wanting to say farewell without conveying feelings," "a daily basis of expressing," and "heart-to-heart communication" (ishin-denshin). For both families and patients, verbalizing feelings was difficult. Our results showed that families' and patients' verbalizing and receiving of feelings must be aligned to understand their communication at the end of life in Japan. Future research is needed to verify how attitude helps promote or inhibit verbalization. Copyright © 2017 John Wiley & Sons, Ltd.

Highlights: • MDM2 is a novel positive regulator of TAp73 transcriptional activity. • MDM2 colocalizes together and physically interacts with E2F1. • Synergistic cooperation of MDM2 and E2F1 is crucial for TAp73 transcription. • MDM2 regulates TAp73 transcriptional activity in a p53-independent manner. - Abstract: TAp73, a structural homologue of p53, plays an important role in tumorigenesis. E2F1 had been reported as a transcriptional regulator of TAp73, however, the detailed mechanism remains to be elucidated. Here we reported that MDM2-silencing reduced the activities of the TAp73 promoters and the endogenous TAp73 expression level significantly; while MDM2 overexpression upregulated them. Wemore » further revealed that the regulation of TAp73 transcriptional activity occurs as a synergistic effect of MDM2 and E2F1, most probably through their physical interaction in the nuclei. Furthermore, we also suggested that MDM2 might be involved in DNA damage-induced TAp73 transcriptional activity. Finally, we elucidated that MDM2-silencing reduced the proliferation rate of colon carcinoma cells regardless of the p53 status. Our data show a synergistic effect of MDM2 and E2F1 on TAp73 transcriptional activity, suggesting a novel regulation pathway of TAp73.« less

Knowledge of Dementia: Do family members understand dementia as a terminal condition?

2017-07-01

Current research identifies advanced dementia to be the terminal phase of this progressive and incurable condition. However, there has been relatively little investigation into how family members of people with advanced dementia understand their relative's condition. In this article, we report on semi-structured interviews with 10 family members of people with advanced dementia, in a residential aged care facility. Using a qualitative, descriptive design, we explored family members' understandings of dementia, whether they were aware that it was a terminal condition, and the ways they developed their understandings. Findings revealed that the majority of family members could not recognize the terminal nature of dementia. Relying on predominantly lay understandings, they had little access to formal information and most failed to conceptualize a connection between dementia and death. Moreover, family members engaged in limited dialogue with aged care staff about such issues, despite their relatives being in an advanced stage of the disease. Findings from our study suggest that how family members understand their relative's condition requires greater attention. The development of staff/family partnerships that promote shared communication about dementia and dying may enhance family members' understandings of the dementia trajectory and the types of decisions they may be faced with during the more advanced stages of the disease.

Although many critical care experts and national organizations support open visitation in intensive care units (ICUs), most ICU visiting policies do not allow unrestricted presence of patients' family members. To describe how well the needs of family members were met in an adult neuroscience ICU with a continuous visitation policy and an adjoining private suite for patients' family members. An exploratory, descriptive study design was used to identify the effects of continuous family visitation in the neuroscience ICU on patients' family members and their needs and experiences during their time in the unit. A convenience sample of consenting family members completed a survey of family need items 72 hours after the patient was admitted to the unit. The most important needs identified by the 45 family members surveyed were items relating to information about the patient, visiting the patient, being given hope, talking with a doctor each day, and being assured that the best care is being given to the patient. Least important items were related to physical comforts for the family members. The vast majority of family members rated their needs as being met for all of the items in the survey and reported a high level of satisfaction with care. In a neuroscience ICU with an open visitation policy and a private suite for patients' family members, family members rated their needs as being met at a high level, unlike in prior studies in units with limitations on family visitation. The rank order of the importance of each need in the survey was similar to rankings in prior studies in a variety of critical care units. ©2016 American Association of Critical-Care Nurses.

2015-09-01

Due to the extensive focus of the literature on the burden placed on families in which a member has been diagnosed with a mental illness such as schizophrenia, there is a need to identify factors that may help these families to be resilient and adapt to their crisis. The aim of this study was to identify family resilience qualities in families in which a member has been diagnosed with schizophrenia. The study comprised 42 families, represented by 33 parents and 9 siblings of the diagnosed family member. Families were recruited from three support groups within the Cape Metropolitan area, Western Cape, South Africa. Qualitative data were obtained through an open-ended question and quantitative data were collected with seven self-report questionnaires. The following family resilience qualities were identified: family income; finding support in their community; family togetherness; family communication style during crises; affirming and supportive communication patterns; family hardiness; commitment to the family; reframing crises as a challenge; and an internal locus of control within the family. The findings may be used by professionals and support group facilitators to enhance the resilience and functioning of families living with a member with schizophrenia. With approximately 1% of the world's population diagnosed with schizophrenia, it is clear that many families are affected when a member has been diagnosed. There is a need to identify factors that may help these families to be resilient. The aim of this study was to identify family resilience qualities in families in which a member has been diagnosed with schizophrenia. The following family resilience qualities were identified as resources that helped them to adapt to the many challenges put to them: family income, finding support in their community, the availability of hospitals, churches and professionals, family togetherness, family communication, family hardiness, commitment to the family, reframing crises

Identifying family members who may struggle in the role of surrogate decision maker.

Although acting as a surrogate decision maker can be highly distressing for some family members of intensive care unit patients, little is known about whether there are modifiable risk factors for the occurrence of such difficulties. To identify: 1) factors associated with lower levels of confidence among family members to function as surrogates and 2) whether the quality of clinician-family communication is associated with the timing of decisions to forego life support. We conducted a prospective study of 230 surrogate decision makers for incapacitated, mechanically ventilated patients at high risk of death in four intensive care units at University of California San Francisco Medical Center from 2006 to 2007. Surrogates completed a questionnaire addressing their perceived ability to act as a surrogate and the quality of their communication with physicians. We used clustered multivariate logistic regression to identify predictors of low levels of perceived ability to act as a surrogate and a Cox proportional hazard model to determine whether quality of communication was associated with the timing of decisions to withdraw life support. There was substantial variability in family members' confidence to act as surrogate decision makers, with 27% rating their perceived ability as 7 or lower on a 10-point scale. Independent predictors of lower role confidence were the lack of prior experience as a surrogate (odds ratio 2.2, 95% confidence interval [1.04-4.46], p=.04), no prior discussions with the patient about treatment preferences (odds ratio 3.7, 95% confidence interval [1.79-7.76], p<.001), and poor quality of communication with the ICU physician (odds ratio 1.2, 95% confidence interval [1.09-1.35] p<.001). Higher quality physician-family communication was associated with a significantly shorter duration of life-sustaining treatment among patients who died (β=0.11, p=.001).

The variability, VR, of critical frequency of E-layer, foE, and ionospheric propagation factor, M(3000)F2 at Ibadan (7.4°N, 3.9°E, 6°S dip) is investigated for local time, seasonal and solar cycle variations. Latitudinal influence of these characteristics is sought by comparison with foE VR and M(3000)F2 VR of Slough ( 51.5°N, 359.4°E, 66.5°N dip) in the European sector, and Singapore (1.3°N,103.8°E, 17.6°S dip) in the Asian sector. While the pattern of foE VR is similar to those of other F2 characteristics with characteristic peaks around dawn and dusk, M(3000)F2 VR shows no clear diurnal trend.A lower bound of foE VR is usually 3% while the maximum VR ranges between 8% and13% at post-sunrise and pre-sunset hours at all the epochs, M(3000)F2 VR is however lower during MSA (about 9%) than during LSA and HSA when it is 4% to about 12-14%. Generally, daytime M(3000)F2 VR is greater than that of foE VR by between 5% and 10%. Furthermore, no latitudinal difference is observed in both characteristics during both HSA and MSA. While nighttime M(3000)F2 VR is about half that of nighttime foF2 VR (the critical frequency of F2-layer ) VR, daytime VR of both characteristics are about equal during the three epochs at Ibadan. For Slough, nighttime M(3000)F2 VR and nighttime foF2 VR as well as the daytime VR of both characteristics are about equal. This difference is most likely due to latitudinal effect.

Bereavement following disasters is a devastating experience for family members. The aim of this study was to examine the long-term mental health effects of losing a loved one in a natural disaster. Ninety-four Norwegians aged 18-80 years who lost close family members in the 2004 Southeast Asian tsunami were evaluated 2 and 6 years after the disaster. The participants were either staying in an affected area at the time of the disaster (i.e., directly exposed) or not (i.e., not directly exposed). The prevalence of psychiatric disorders was assessed by the MINI International Neuropsychiatric Interview (M.I.N.I). Prolonged grief disorder (PGD) was self-reported using the Inventory of Complicated Grief (ICG), and functional impairment was self-reported using the Work and Social Adjustment Scale (WSAS). We did not identify a significant decrease in the prevalence of PGD, posttraumatic stress disorder (PTSD), or major depressive disorder (MDD) from 2 to 6 years. Approximately, one-third of the bereaved (36%) had a psychiatric disorder 6 years after the tsunami. The most common disorder was PGD (12%) followed by general anxiety disorder (GAD, 11%), agoraphobia (11%), and MDD (10%). The prevalence of PTSD and MDD was higher among family members who were directly exposed to the disaster compared to those who were not (21 vs. 0%, and 25 vs. 3%). PGD was associated with functional impairment independent of other disorders. Loss of a close family member in a natural disaster can have a substantial adverse long-term effect on mental health and everyday functioning. © 2014 Wiley Periodicals, Inc.

To examine the caregiving impact of those who support a family member with intellectual disability and epilepsy. An online, qualitative international survey was conducted via the auspices of the International Bureau of Epilepsy with various stakeholders who support individuals who have intellectual disability and epilepsy. Qualitative comments were analyzed from respondents who identified themselves as family members (n=48; 36%) who referred specifically to the impact of supporting a family member with these combined disabilities. Four main domains, which were comprised of ten themes, were derived from the qualitative data using Braun and Clarke's qualitative framework. These domains comprised (1) practical concerns, (2) disrupted family dynamics, (3) emotional burden and (4) positive experiences. In combination these themes illustrate the pervasive impact on family life for those supporting an individual with complex needs. Financial concerns, coordination and responsibility of care, diverted attention from other family members and social isolation all contributed a significant burden of care for family members. Positive aspects were, however, also cited including the closeness of the family unit and a fostering of altruistic behavior. The study provides an insight into an under-researched area. The burden of caring for a family member across the lifespan has a largely negative and pervasive impact. Targeted service provision could contribute to an amelioration of the challenges faced by these families. Copyright © 2014 British Epilepsy Association. Published by Elsevier Ltd.

2016-07-01

A secondary analysis of data from adult female prison inmates in the mid-Atlantic United States defined relationships between having incarcerated adult family members during childhood and neurological outcomes. Of 135 inmates, 99 (60%) had one or more incarcerated adult family members during childhood. Regression analyses revealed that having incarcerated adult family members was related to greater frequency and severity of childhood abuse and higher incidence of neurological deficits in adulthood, especially related to traumatic brain injuries, compared to those without incarcerated adult family members. Along with being role models, adult family members impact the neurological health of children throughout their life-span.

Despite increased functionality for obtaining family history in a structured format within electronic health record systems, clinical notes often still contain this information. We developed and evaluated an Unstructured Information Management Application (UIMA)-based natural language processing (NLP) module for automated extraction of family history information with functionality for identifying statements, observations (e.g., disease or procedure), relative or side of family with attributes (i.e., vital status, age of diagnosis, certainty, and negation), and predication ("indicator phrases"), the latter of which was used to establish relationships between observations and family member. The family history NLP system demonstrated F-scores of 66.9, 92.4, 82.9, 57.3, 97.7, and 61.9 for detection of family history statements, family member identification, observation identification, negation identification, vital status, and overall extraction of the predications between family members and observations, respectively. While the system performed well for detection of family history statements and predication constituents, further work is needed to improve extraction of certainty and temporal modifications.

This study examined the prevalence of perceived stress and depressive symptoms in cancer survivors and their family members compared with subjects without cancer and without family members with cancer. The subjects of this cross-sectional study were adults ≥19 years old who participated in the 2012 Korea Community Health Survey. Stress and depressive symptoms in cancer survivors and their family members were assessed and compared to symptoms in control groups by chi-square tests and multiple logistic regression analyses. Of the 6783 cancer survivors, 26.9% and 8.7% reported having stress and depressive symptoms, respectively, and 27.7% and 5.9% of family members of cancer survivors reported having stress and depressive symptoms, respectively. Cancer survivors showed higher adjusted odds ratio (aOR) for stress (aOR = 1.26, 95% confidence interval (CI) = 1.16-1.37) and depressive symptoms (aOR = 1.82, 95% CI = 1.57-2.11) than subjects without cancer history. Family members of cancer survivors showed a higher OR for stress and depressive symptoms than subjects without a family member who survived cancer. Cancer survivors and family members of cancer survivors had more stress and depressive symptoms than controls. Careful management for cancer patients and their family members should include screening for stress and depression to improve mental health associated with cancer survivorship.

The World Health Organization recommends direct observation of treatment (DOT) to support patients with tuberculosis (TB) and to ensure treatment completion. As per national programme guidelines in India, a DOT provider can be anyone who is acceptable and accessible to the patient and accountable to the health system, except a family member. This poses challenges among children with TB who may be more comfortable receiving medicines from their parents or family members than from unfamiliar DOT providers. We conducted a non-inferiority trial to assess the effect of family DOT on treatment success rates among children with newly diagnosed TB registered for treatment during June-September 2012. We randomly assigned all districts (n = 30) in Gujarat to the intervention (n = 15) or usual-practice group (n = 15). Adult family members in the intervention districts were given the choice to become their child's DOT provider. DOT was provided by a non-family member in the usual-practice districts. Using routinely collected clinic-based TB treatment cards, we compared treatment success rates (cured and treatment completed) between the two groups and the non-inferiority limit was kept at 5%. Of 624 children with newly diagnosed TB, 359 (58%) were from intervention districts and 265 (42%) were from usual-practice districts. The two groups were similar with respect to baseline characteristics including age, sex, type of TB, and initial body weight. The treatment success rates were 344 (95.8%) and 247 (93.2%) (p = 0.11) among the intervention and usual-practice groups respectively. DOT provided by a family member is not inferior to DOT provided by a non-family member among new TB cases in children and can attain international targets for treatment success.

Surgical residents often need to break bad news (BBN) to patients and family members. While communication skills are a core competency in residency training, these specific skills are rarely formally taught. We piloted a simulation training to teach pediatric surgical residents how to compassionately BBN of an unexpected, traumatic pediatric death to surviving family members. This training was unique in that it was influenced by family systems theory and was a collaborative effort between our institution's surgery residency and medical family therapy (MedFT) programs. This study provides outcomes of surgery residents' communication skills, attitudes, and self-perceptions after a BBN simulation activity with standardized family members at a major academic teaching hospital. Each resident participated in two 30-min simulations and received feedback from observers. Outcome data were collected through self-assessments completed before, immediately after, and 6 months after the simulation. Participants were 15 surgery residents, and MedFT students served as simulated family members and trainers. A statistically significant change with medium to large effect sizes in participant self-reported perceptions of skill and confidence were documented and maintained over 6 months. Responses to open-ended questions supported practice changes in response to the training. This collaborative training promoted significant improvement in resident compassionate communication skills. The curriculum was highly valued by the learners and resulted in sustained application of learned skills with patients and families. Our novel approach was feasible with promising results that warrant further investigation and could be reproduced in other institutions with similar programs.

In winegrapes (Vitis spp.), fruit quality traits such as berry color, total soluble solids content (SS), malic acid content (MA), and yeast assimilable nitrogen (YAN) affect fermentation or wine quality, and are important traits in selecting new hybrid winegrape cultivars. Given the high genetic diversity and heterozygosity of Vitis species and their tendency to exhibit inbreeding depression, linkage map construction and quantitative trait locus (QTL) mapping has relied on F1 families with the use of simple sequence repeat (SSR) and other markers. This study presents the construction of a genetic map by single nucleotide polymorphisms identified through genotyping-by-sequencing (GBS) technology in an F2 mapping family of 424 progeny derived from a cross between the wild species V. riparia Michx. and the interspecific hybrid winegrape cultivar, ‘Seyval’. The resulting map has 1449 markers spanning 2424 cM in genetic length across 19 linkage groups, covering 95% of the genome with an average distance between markers of 1.67 cM. Compared to an SSR map previously developed for this F2 family, these results represent an improved map covering a greater portion of the genome with higher marker density. The accuracy of the map was validated using the well-studied trait berry color. QTL affecting YAN, MA and SS related traits were detected. A joint MA and SS QTL spans a region with candidate genes involved in the malate metabolism pathway. We present an analytical pipeline for calling intercross GBS markers and a high-density linkage map for a large F2 family of the highly heterozygous Vitis genus. This study serves as a model for further genetic investigations of the molecular basis of additional unique characters of North American hybrid wine cultivars and to enhance the breeding process by marker-assisted selection. The GBS protocols for identifying intercross markers developed in this study can be adapted for other heterozygous species. PMID:26974672

We developed a hospital-based cardiopulmonary resuscitation (CPR) training model focused on the target population (family members of patients with potential risks for cardiac arrest) and compared the outcome of CPR training between target and non-target populations for validity. Family members of patients in training were divided into three groups on the basis of patients' diseases, as follows: 1) the cardio-specific (CS) risk group, including family members of patients with cardiac disease at risk of cardiac arrest; 2) the cardiovascular (CV) risk group, including family members of patients with risk factors for cardiovascular disease; and 3) the no-risk group. Pre- and posttraining surveys and skill tests as well as a post-training 3-month telephone survey were conducted. Educational outcomes were analyzed. A total of 203 family members were enrolled into 21 CPR training classes. The CS group (n=88) included elderly persons and housewives with a lower level of education compared with the CV (n=79) and no-risk groups (n=36). The CS group was motivated by healthcare professionals and participated in the training course. The CS, CV, and no-risk groups showed improvements in knowledge, willingness to perform CPR, and skills. Despite the older age and lower level of education in the CS group, the effects of education were similar to those in the other groups. A high rate of response and secondary propagation of CPR training were observed in the CS group. Family members of patients with heart disease could be an appropriate target population for CPR training, particularly in terms of recruitment and secondary propagation. Targeted intervention may be an effective training strategy to improve bystander CPR rates.

Conservation and divergence of C-terminal domain structure in the retinoblastoma protein family

DOE Office of Scientific and Technical Information (OSTI.GOV)

Liban, Tyler J.; Medina, Edgar M.; Tripathi, Sarvind

The retinoblastoma protein (Rb) and the homologous pocket proteins p107 and p130 negatively regulate cell proliferation by binding and inhibiting members of the E2F transcription factor family. The structural features that distinguish Rb from other pocket proteins have been unclear but are critical for understanding their functional diversity and determining why Rb has unique tumor suppressor activities. We describe here important differences in how the Rb and p107 C-terminal domains (CTDs) associate with the coiled-coil and marked-box domains (CMs) of E2Fs. We find that although CTD–CM binding is conserved across protein families, Rb and p107 CTDs show clear preferences formore » different E2Fs. A crystal structure of the p107 CTD bound to E2F5 and its dimer partner DP1 reveals the molecular basis for pocket protein–E2F binding specificity and how cyclin-dependent kinases differentially regulate pocket proteins through CTD phosphorylation. Our structural and biochemical data together with phylogenetic analyses of Rb and E2F proteins support the conclusion that Rb evolved specific structural motifs that confer its unique capacity to bind with high affinity those E2Fs that are the most potent activators of the cell cycle.« less

We previously identified two distinct molecular subtypes of osteosarcoma through gene expression profiling. These subtypes are associated with distinct tumor behavior and clinical outcomes. Here, we describe mechanisms that give rise to these molecular subtypes. Using bioinformatic analyses, we identified a significant association between deregulation of the retinoblastoma (RB)-E2F pathway and the molecular subtype with worse clinical outcomes. Xenotransplantation models recapitulated the corresponding behavior for each osteosarcoma subtype; thus, we used cell lines to validate the role of the RB-E2F pathway in regulating the prognostic gene signature. Ectopic RB resets the patterns of E2F regulated gene expression in cells derived from tumors with worse clinical outcomes (molecular phenotype 2) to those comparable with those observed in cells derived from tumors with less aggressive outcomes (molecular phenotype 1), providing a functional association between RB-E2F dysfunction and altered gene expression in osteosarcoma. DNA methyltransferase and histone deacetylase inhibitors similarly reset the transcriptional state of the molecular phenotype 2 cells from a state associated with RB deficiency to one seen with RB sufficiency. Our data indicate that deregulation of RB-E2F pathway alters the epigenetic landscape and biological behavior of osteosarcoma. PMID:26378234

We have identified a close homologue of L1 (CHL1) in the mouse. CHL1 comprises an N-terminal signal sequence, six immunoglobulin (Ig)-like domains, 4.5 fibronectin type III (FN)-like repeats, a transmembrane domain and a C-terminal, most likely intracellular domain of approximately 100 amino acids. CHL1 is most similar in its extracellular domain to chicken Ng-CAM (approximately 40% amino acid identity), followed by mouse L1, chicken neurofascin, chicken Nr-CAM, Drosophila neuroglian and zebrafish L1.1 (37-28% amino acid identity), and mouse F3, rat TAG-1 and rat BIG-1 (approximately 27% amino acid identity). The similarity with other members of the Ig superfamily [e.g. neural cell adhesion molecule (N-CAM), DCC, HLAR, rse] is 16-11%. The intracellular domain is most similar to mouse and chicken Nr-CAM, mouse and rat neurofascin (approximately 60% amino acid identity) followed by chicken neurofascin and Ng-CAM, Drosophila neuroglian and zebrafish L1.1 and L1.2 (approximately 40% amino acid identity). Besides the high overall homology and conserved modular structure among previously recognized members of the L1 family (mouse/human L1/rat NILE; chicken Ng-CAM; chicken/mouse Nr-CAM; Drosophila neuroglian; zebrafish L1.1 and L1.2; chicken/mouse neurofascin/rat ankyrin-binding glycoprotein), criteria characteristic of L1 were identified with regard to the number of amino acids between positions of conserved amino acid residues defining distances within and between two adjacent Ig-like domains and FN-like repeats. These show a collinearity in the six Ig-like domains and four adjacent FN-like repeats that is remarkably conserved between L1 and molecules containing these modules (designated the L1 family cassette), including the GPI-linked forms of the F3 subgroup (mouse F3/chicken F11/human CNTN1; rat BIG-1/mouse PANG; rat TAG-1/mouse TAX-1/chicken axonin-1). The colorectal cancer molecule (DCC), previously introduced as an N-CAM-like molecule, conforms to the L1 family

The crystal structure, magnetic ordering, and electrical resistivity of TlF e1.6S e2 were studied at high pressures. Below ˜7 GPa , TlF e1.6S e2 is an antiferromagnetically ordered semiconductor with a ThC r2S i2 -type structure. The insulator-to-metal transformation observed at a pressure of ˜7 GPa is accompanied by a loss of magnetic ordering and an isostructural phase transition. In the pressure range ˜7.5 -11 GPa a remarkable downturn in resistivity, which resembles a superconducting transition, is observed below 15 K. We discuss this feature as the possible onset of superconductivity originating from a phase separation in a small fraction of the sample in the vicinity of the magnetic transition.

Stochastic E2F activation and reconciliation of phenomenological cell-cycle models.

Lee, Tae J; Yao, Guang; Bennett, Dorothy C; Nevins, Joseph R; You, Lingchong

2010-09-21

The transition of the mammalian cell from quiescence to proliferation is a highly variable process. Over the last four decades, two lines of apparently contradictory, phenomenological models have been proposed to account for such temporal variability. These include various forms of the transition probability (TP) model and the growth control (GC) model, which lack mechanistic details. The GC model was further proposed as an alternative explanation for the concept of the restriction point, which we recently demonstrated as being controlled by a bistable Rb-E2F switch. Here, through a combination of modeling and experiments, we show that these different lines of models in essence reflect different aspects of stochastic dynamics in cell cycle entry. In particular, we show that the variable activation of E2F can be described by stochastic activation of the bistable Rb-E2F switch, which in turn may account for the temporal variability in cell cycle entry. Moreover, we show that temporal dynamics of E2F activation can be recast into the frameworks of both the TP model and the GC model via parameter mapping. This mapping suggests that the two lines of phenomenological models can be reconciled through the stochastic dynamics of the Rb-E2F switch. It also suggests a potential utility of the TP or GC models in defining concise, quantitative phenotypes of cell physiology. This may have implications in classifying cell types or states.

Objective This study examines the impact of Family Healthware™ on communication behaviors; specifically, communication with family members and health care providers about family health history. Methods A total of 3786 participants were enrolled in the Family Healthware™ Impact Trial (FHITr) in the United States from 2005-7. The trial employed a two-arm cluster-randomized design, with primary care practices serving as the unit of randomization. Using generalized estimating equations (GEE), analyses focused on communication behaviors at 6 month follow-up, adjusting for age, site and practice clustering. Results A significant interaction was observed between study arm and baseline communication status for the family communication outcomes (ps<.01), indicating that intervention had effects of different magnitude between those already communicating at baseline and those who were not. Among participants who were not communicating at baseline, intervention participants had higher odds of communicating with family members about family history risk (OR=1.24, p=0.042) and actively collecting family history information at follow-up (OR=2.67, p=0.026). Family Healthware™ did not have a significant effect on family communication among those already communicating at baseline, or on provider communication, regardless of baseline communication status. Greater communication was observed among those at increased familial risk for a greater number of diseases. Conclusion Family Healthware™ prompted more communication about family history with family members, among those who were not previously communicating. Efforts are needed to identify approaches to encourage greater sharing of family history information, particularly with health care providers. PMID:25901453

Members of the bcl-2 and caspase families regulate nuclear degeneration during chick lens fibre differentiation.

Wride, M A; Parker, E; Sanders, E J

1999-09-01

The optical clarity of the lens is ensured by the programmed removal of nuclei and other organelles from the lens fibre cells during development. The morphology of the degenerating nuclei is similar to that observed during apoptosis and is accompanied by DNA fragmentation. Proteins encoded by the bcl-2 proto-oncogene family are important in either promoting or inhibiting apoptosis, and caspases are involved in downstream proteolytic events. Here, the expression of bcl-2 family members (bcl-2, bax, bad, and bcl-x(s/l)) and caspases-1, -2, -3, -4, and -6 was investigated through a range of stages of chick lens development using immunocytochemistry, Western blotting, and affinity labelling for caspases using biotinylated caspase inhibitors. Using differentiating lens epithelial cell cultures, it was demonstrated that the addition to cultures of synthetic peptide inhibitors of caspases -1, -2, -4, -6, and -9 brought about a 50-70% reduction in the number of degenerating nuclei per unit area of culture, as assessed by image analysis. These effects were comparable to those seen when general inhibitors of caspases were added to cultures. On the other hand, inhibitors of caspases-3 and -8 were not effective in significantly reducing the number of TUNEL-labelled nuclei. Expression of the caspase substrates poly(ADP-ribose) polymerase (PARP) and the 45-kDa subunit of DNA fragmentation factor (DFF 45) was also observed in the developing lens. Western blots of cultures to which caspase inhibitors were added revealed alterations in the PARP cleavage pattern, but not in that of DFF. These results demonstrate a role for members of the bcl-2 family and caspases in the degeneration of lens fibre cell nuclei during chick secondary lens fibre development and support the proposal that this process has many characteristics in common with apoptosis.

To characterize illness perceptions among persons with mild cognitive impairment (PWMCI) and their family care partners, and to examine whether PWMCI's and their family care partners' illness perceptions were associated with their own, as well as the other member of the dyad's, emotional reactions to MCI. This cross-sectional study of PWMCI and their family care partners (n = 60 dyads) used patient and relative versions of the Revised Illness Perception Questionnaire (IPQ-R) to assess metacognitive and emotional features of illness perception in MCI along 5 dimensions of perceived: seriousness of potential consequences, personal controllability, timeline, fluctuation (cycling) of symptoms, and illness coherence (clear vs. confusing). As compared to family members, PWMCI perceived MCI to be less potentially serious and to be more within their personal control, but dyads otherwise shared similar perceptions of MCI. Among PWMCI, perceived seriousness of the potential consequences of MCI was the only dimension to be significantly correlated with emotional distress. For family members, increased MCI-related emotional distress was significantly associated with perceptions of MCI as potentially serious, permanent, or confusing. A dyadic analysis using APIM showed that MCI-related emotional distress, in both PWMCI and family members, was linked to the PWMCI's perception of the seriousness of MCI. MCI-related education and support should be tailored for both the PWMCI and family member audiences, while acknowledging interdependence of illness perceptions within family units. Tailored information and support will be critical in managing MCI going forward, as illness perceptions are likely key factors on which individuals will plan for the future or base medical decisions. © The Author 2015.

Normal cell growth is governed by a complicated biological system, featuring multiple levels of control, often deregulated in cancers. The role of microRNAs (miRNAs) in the control of gene expression is now increasingly appreciated, yet their involvement in controlling cell proliferation is still not well understood. Here we investigated the mammalian cell proliferation control network consisting of transcriptional regulators, E2F and p53, their targets and a family of 15 miRNAs. Indicative of their significance, expression of these miRNAs is downregulated in senescent cells and in breast cancers harboring wild-type p53. These miRNAs are repressed by p53 in an E2F1-mediated manner. Furthermore, we show that these miRNAs silence antiproliferative genes, which themselves are E2F1 targets. Thus, miRNAs and transcriptional regulators appear to cooperate in the framework of a multi-gene transcriptional and post-transcriptional feed-forward loop. Finally, we show that, similarly to p53 inactivation, overexpression of representative miRNAs promotes proliferation and delays senescence, manifesting the detrimental phenotypic consequence of perturbations in this circuit. Taken together, these findings position miRNAs as novel key players in the mammalian cellular proliferation network. PMID:19034270

Borrelia burgdorferi is the causative agent of Lyme disease, which can be acquired after the bite of an infected Ixodes tick. As a strategy to resist the innate immunity and to successfully spread and proliferate, B. burgdorferi expresses a set of outer membrane proteins that are capable of binding complement regulator factor H (CFH), factor H-like protein 1 (CFHL-1) and factor H-related proteins (CFHR) to avoid complement-mediated killing. B. burgdorferi B31 contains three proteins that belong to the Erp (OspE/F-related) protein family and are capable of binding CFH and some CFHRs, namely ErpA, ErpC and ErpP. We have determined the crystal structure of ErpP at 2.53Å resolution and the crystal structure of ErpC at 2.15Å resolution. Recently, the crystal structure of the Erp family member OspE from B. burgdorferi N40 was determined in complex with CFH domains 19-20, revealing the residues involved in the complex formation. Despite the high sequence conservation between ErpA, ErpC, ErpP and the homologous protein OspE (78-80%), the affinity for CFH and CFHRs differs markedly among the Erp family members, suggesting that ErpC may bind only CFHRs but not CFH. A comparison of the binding site in OspE with those of ErpC and ErpP revealed that the extended loop region, which is only observed in the potential binding site of ErpC, plays an important role by preventing the binding of CFH. These results can explain the inability of ErpC to bind CFH, whereas ErpP and ErpA still possess the ability to bind CFH. Copyright © 2015 Elsevier B.V. All rights reserved.

Solving the dilemma of the organ shortage in Malaysia requires educating Malaysians about organ donation and transplantation. This paper aims at exploring the average Malaysian households ' preferred channels of campaigns and the preferred campaigners in a family setting, targeting at the dialysis family members. We analyzed the responses of 350 respondents regarding organ donation campaigns. The respondents are 2 family members of 175 dialysis patients from 3 different institutions. The information on respondents' willingness to donate and preferred method and channel of organ donation campaign were collected through questionnaire. Malaysian families have a good tendency to welcome campaigns in both the public and private (their homes) spheres. We also found that campaigns facilitated by the electronic media (Television and Radio) and executed by experienced doctors are expected to optimize the outcomes of organ donation, in general. Chi-square tests show that there are no significant differences in welcoming campaigns among ethnics. However, ethnics preferences over the campaign methods and campaigners are significantly different (P <0.05). Ethnic differences imply that necessary modifications on the campaign channels and campaigners should also be taken under consideration. By identifying the preferred channel and campaigners, this study hopes to shed some light on the ways to overcome the problem of organ shortage in Malaysia.

To study E2F3a expression and its clinical significance in children with acute lymphoblastic leukemia (ALL). We quantified E2F3a expression at diagnosis in 148 children with ALL by real-time PCR. In the test cohort (n = 48), receiver operating characteristic (ROC) curve was used to find the best cut-off point to divide the patients into E2F3a low- and high-expression groups. The prognostic significance of E2F3a expression was investigated in the test cohort and confirmed in the validation cohort (n = 100). The correlations of E2F3a expression with the clinical features and treatment outcome of these patients were analyzed. ROC curve analysis indicated that the best cut-off point of E2F3a expression was 0.3780. In the test cohort, leukemia-free survival (LFS) and event-free survival (EFS) of the low-expression group were lower than those of the high-expression group (log rank: P = 0.026 for both). This finding was verified in the validation cohort. LFS, EFS, and overall survival were also lower in the low-expression group than in the high-expression group (log rank, P = 0.015, 0.008, and 0.002 respectively). E2F3a low expression was correlated with the existence of BCR-ABL fusion. An algorithm composed of E2F3a expression and minimal residual disease (MRD) could predict relapse or induction failure more precisely than current risk stratification. These results were still significant in the ALL patients without BCR-ABL fusion. Low expression of E2F3a was associated with inferior prognosis in childhood ALL. An algorithm composed of E2F3a expression and MRD could predict relapse or induction failure more precisely than that of the current risk stratification. © 2014 John Wiley & Sons A/S.

The aim of this study was to determine the effects of the psychoeducation received by the family members of the patients with first-episode schizophrenia on the expressed emotion (EE) and the family functioning of the family members. This study has a quasi-experimental design with a control group. The sample of the study was 60 family members (30 experimental -30 control) of the patients with first-episode schizophrenia. The experimental group received 9 weeks of psychoeducation as a group. EE and family functioning were assessed at the beginning and at the end of the psychoeducation program. EE criticism/hostility and over involvement-protecting-intervention levels of the family members have decreased at the end of the psychoeducation (p < 0.05). Family functioning has changed too at the end of the psychoeducation (p < 0.05), and assessed as more healthy. Consequently, early psychoeducational groups may be effective in decreasing EE level and improving the family functioning for a family member of patient with first-episode schizophrenia.

Community-based mental health care requires the involvement of staff, patients, and their family members when both planning intervention programmes and evaluating mental health outcomes. The present study aimed to compare the perceptions of these three groups on two important subjective mental health outcome measures--needs for care and service satisfaction--to identify potential areas of discrepancy. The sample consisted of patients with a DSM diagnosis of psychosis and attending either outpatient or day centres operating in a community-based care system. Staff, patients and family members were assessed by using the CAN and the VSSS to evaluate, respectively, needs for care and service satisfaction. Kappa statistics were computed to assess agreement in the three groups. Patients identified significantly fewer basic (e.g. daytime activities, food, accommodation) and functioning needs (e.g. self-care, looking after home, etc.) than staff or family members. Only fair levels of agreement were found in the three groups (average kappa was 0.48 for staff and patients, 0.54 for staff and family members, and 0.45 for patients and relatives), with patients and family members showing more areas of discrepancies in both needs and service satisfaction. These findings provide further support for the idea that mental health services should routinely involve patients and their relatives when planning and evaluating psychiatric intervention and that this policy is a premise for developing a partnership care model.

Mandolin Family Instruments

NASA Astrophysics Data System (ADS)

Cohen, David J.; Rossing, Thomas D.

The mandolin family of instruments consists of plucked chordophones, each having eight strings in four double courses. With the exception of the mandobass, the courses are tuned in intervals of fifths, as are the strings in violin family instruments. The soprano member of the family is the mandolin, tuned G3-D4-A4-E5. The alto member of the family is the mandola, tuned C3-G3-D4-A4. The mandola is usually referred to simply as the mandola in the USA, but is called the tenor mandola in Europe. The tenor member of the family is the octave mandolin, tuned G2-D3-A3-E4. It is referred to as the octave mandolin in the USA, and as the octave mandola in Europe. The baritone member of the family is the mandocello, or mandoloncello, tuned C2-G2-D3-A3. A variant of the mandocello not common in the USA is the five-course liuto moderno, or simply liuto, designed for solo repertoire. Its courses are tuned C2-G2-D3-A3-E4. A mandobass was also made by more than one manufacturer during the early twentieth century, though none are manufactured today. They were fretted instruments with single string courses tuned E1-A1-D2-G2. There are currently a few luthiers making piccolo mandolins, tuned C4-G4-D5-A5.

Research has infrequently looked beyond the injured worker when gauging the burden of occupational injury. We explored the relationship between occupational injury and musculoskeletal disorders (MSDs) among family members of injured workers. We used 2005 and 2006 Truven Health Analytics databases, which contain information on workers' compensation and family healthcare claims. We used descriptive analyses, and negative binomial and two-part models. Family members of severely injured workers had a 15% increase in the total number of MSD outpatient claims and a 34% increase in the mean cost of MSD claims compared to family members of non-severely injured workers within 3 months after injury. Extrapolating cost results to the national level implies that severe occupational injury would be associated with between $29 and $33 million additional cost of family member outpatient MSD claims. Occupational injury can impose a formerly unrecognized health burden on family members of injured workers. Published 2015.

The objective of our study was to determine the satisfaction levels of family members of patients with advanced-stage cancer. This descriptive study was conducted in the palliative care and medical oncology clinics of a university hospital in the province of Izmir between April of 2011 and January of 2012. The study sample consisted of a total of 145 family members, who were selected from among the family members of patients with advanced-stage cancer receiving palliative treatment. The study data were obtained using the Patient Description Form and Family Satisfaction Scale during face-to-face interviews with patients. Some 67% of patients were female and 33% male, 70% were married, 35% were high school graduates, and 34.5% were housewives. The average total family satisfaction score was 76.87 ± 1.14, and the average scores for the component variables were as follows: information giving 74.37 ± 1.28, availability of care 78.40 ± 1.17, physical care 78.99 ± 1.09, and psychosocial care 74.52 ± 1.30. We found a relationship between the level of satisfaction of family members and (1) gender, (2) occupation, (3) presence of someone supporting the care, and (4) possession of sufficient information about the patient (p < 0.05). Satisfaction levels of participants were determined to be high. We found that family member satisfaction levels were affected by gender and occupation, the existence of someone supporting the care, and possession of sufficient information about the patient.

Background Y-box binding factor 1 (YB-1) has been associated with prognosis in many tumor types. Reduced YB-1 expression inhibits tumor cell growth, but the mechanism is unclear. Methods YB-1 mRNA levels were compared with tumor grade and histology using microarray data from 771 breast cancer patients and with disease-free survival and distant metastasis–free survival using data from 375 of those patients who did not receive adjuvant therapy. Microarrays were further searched for genes that had correlated expression with YB-1 mRNA. Small interfering RNA (siRNA) was used to study the effects of reduced YB-1 expression on growth of three tumor cell lines (MCF-7 breast, HCT116 colon, and A549 lung cancer cells), on tumorigenesis by A549 cells in nude mice, and on global transcription in the three cancer cell lines. Reporter gene assays were used to determine whether YB-1 siRNAs affected the expression of E2F1, and chromatin immunoprecipitation was used to determine whether YB-1 bound to various E2F promoters as well as E2F1-regulated promoters. All P values were from two-sided tests. Results YB-1 levels were elevated in more aggressive tumors and were strongly associated with poor disease-free survival and distant metastasis–free survival. YB-1 expression was often associated with the expression of genes with E2F sites in their promoters. Cells expressing YB-1 siRNA grew substantially more slowly than control cells and formed tumors less readily in nude mice. Transcripts that were altered in cancer cell lines with YB-1 siRNA included 32 genes that are components of prognostic gene expression signatures. YB-1 regulated expression of an E2F1 promoter–reporter construct in A549 cells (eg, relative E2F1 promoter activity with control siRNA = 4.04; with YB-1 siRNA = 1.40, difference= −2.64, 95% confidence interval = −3.57 to −1.71, P < .001) and bound to the promoters of several well-defined E2F1 target genes. Conclusion YB-1 expression is associated with the

Introduction: The overwhelming effects of cancer could be catastrophic for the patients and their family members, putting them at risk of experiencing uncertainty, loss, and an interruption in life. Also, it can influence their sense of meaning, a fundamental need equated with the purpose in life. Accordingly, this study aimed to compare the meaning in life (MiL) of patients with cancer and their family members. Methods: This descriptive comparative study was conducted on 400 patients with cancer and their family members admitted to university hospitals in Tabriz and Ardebil provinces, Iran. The participants were sampled conveniently and the Life Evaluation Questionnaire (LEQ) were used for collecting data analyzed through descriptive and inferential statistics in SPSS ver. 13 Software. Results: The mean score for the MiL of the patients with cancer and their family members was 119 (16.92) and 146.2 (17.07), respectively. There was a significant difference between patients with cancer and their family members in terms of MiL. Conclusion: The MiL of patients with cancer is lower than that of their family members, which indicates the need for further attention to the psychological processes and their modification in Iranian healthcare systems.

Family members' experiences of personal assistance given to a relative with disabilities.

Personal assistance is a type of home care common to many countries even though entitlement and legislative framework may vary from country to country. At present, there exists no knowledge about the family members' experiences of such assistance; therefore, the aim of this study was to investigate family members' experiences of personal assistance given to a relative of working age with a functional disability. Twenty-five family members who had a relative with a severe neurological disease in Sweden were interviewed about the significance of personal assistance, and the qualitative interviews were subjected to qualitative latent content analysis. The overall findings verify the close connection between the family members' experiences and their perception of the quality of the caring relationship between the personal assistant and the person with disability. The main finding was an appreciation of the personal assistance on the part of the family members. However, in situations where the encounter between the assistant and the relative with disability was perceived negatively, the family members experienced great anxiety. The shortcomings were the inability to maintain a private life with assistance and the limitation of choice because of the shortage of personal assistants. Beyond these general findings, this study found that personal assistance was experienced by the family members in terms of dignity and empowering care. This theme was generated from seven subthemes: Insight into private life, Security through the close relation, Social life through freedom of movement, Influence over the organisation of assistance, Self-determination and understanding, Friendship and mutual respect and Adaption to the dependency on assistance. The findings indicate that responsible officials, work leaders and assistants need constantly to improve the implementation of the law. In such efforts, the experiences of family members described in this study are a source of knowledge

Sodium reduction is very important in preventing cardiovascular diseases, especially in regions with high salt intake such as Japan. One strategy for salt reduction is to raise consumer awareness of the need to reduce daily salt intake. We investigated whether cooking classes given to housewives focussing on salt reduction would influence not only their own consumption behaviour but also that of their family members. Single-blinded, cluster randomized trial. We randomly assigned housewives to participate in cooking classes focussing on salt reduction (intervention group) or lectures about a healthy lifestyle (control group). The main outcome measure was the difference in estimated daily salt intake by spot urine sampling of housewives and their family members 2 months after intervention between the groups. A total of 35 housewives and 33 family members were randomized. The mean daily salt intake was 10.00 (standard deviation [SD] 1.75) g/day in the control group (17 housewives and 15 family members) and 9.57 (SD 2.45) g/day in the intervention group (18 housewives and 18 family members) at baseline. Two months after the intervention, the mean salt intake was 10.30 (SD 1.78) g/day in the control group and 8.95 (SD 2.45) g/day in the intervention group. The mean difference was -1.19 g/day (95% confidence interval -2.29, -0.09; P = 0.034). A similar tendency was observed in the subgroups of housewives and family members. Our trial suggested that the effects of cooking classes focussing on salt reduction for housewives could be transferred to family members (UMIN-CTR: 000018870).

When a woman is diagnosed with breast cancer, it affects all family members. Therefore, the aim of this study was to elucidate family members lived experience when a family member is diagnosed with breast cancer. The study had a hermeneutic phenomenological design including individual conversational interviews conducted face-to-face with six women with breast cancer and their family members at two different points of time, in order to elucidate families' lived experience, both as individuals and as a unit, from each family member's perspective. Living as a family in the presence of breast cancer is a challenging endeavour to regain an ordinary, safe life, hoping to reach a safe haven. The families felt that life as they knew it had disappeared and they were fumbling in the dark, trying to find support and guidance on their path to ordinary life. The family members were pursuing balance by attempting to keep the family together and maintaining a positive attitude while battling against fear and treatment-related side effects. Finally, the families were struggling with guilt and inadequacy, due to their difficulties in communicating the emotional distress that the illness brought upon them, at the same time as they felt abandoned by the healthcare professionals. Families experience an unmet need of information and support, which implies that healthcare professionals may want to acknowledge and include the family already at the time of diagnosis in order to help them endure and cope with the distressing experience and thus increase their wellbeing.

Communication with families about mechanical ventilation may be more effective once we gain a better understanding of what families experience and understand about this life support technology when their loved ones are admitted to the intensive care unit (ICU). We conducted in-depth interviews with family members of 27 critically ill patients who required mechanical ventilation for > or = 7 days and had an estimated ICU mortality of > or = 50%. Team members reviewed transcripts independently and used grounded theory analysis. The central theme of family members' experience with mechanical ventilation was "living with dying." Initial reactions to the ventilator were of shock and surprise. Family members perceived no option except mechanical ventilation. Although the ventilator kept the patient alive, it also symbolized proximity to death. In time, families became accustomed to images of the ICU as ventilation became more familiar and routine. Their shock and horror were replaced by hope that the ventilator would allow the body to rest, heal, and recover. However, ongoing exposure to their loved one's critical illness and the new role as family spokesperson were traumatizing. Family members' experiences and their understanding of mechanical ventilation change over time, influenced by their habituation to the ICU environment and its routines. They face uncertainty about death, but maintain hope. Understanding these experiences may engender more respectful, meaningful communication about life support with families.

Structural Basis of Substrate Specificity and Regiochemistry in the MycF/TylF Family of Sugar O -Methyltransferases.

Bernard, Steffen M.; Akey, David L.; Tripathi, Ashootosh

Sugar moieties in natural products are frequently modified by O-methylation. In the biosynthesis of the macrolide antibiotic mycinamicin, methylation of a 6'-deoxyallose substituent occurs in a stepwise manner first at the 2'- and then the 3'-hydroxyl groups to produce the mycinose moiety in the final product. The timing and placement of the O-methylations impact final stage C-H functionalization reactions mediated by the P450 monooxygenase MycG. The structural basis of pathway ordering and substrate specificity is unknown. A series of crystal structures of MycF, the 3'-O-methyltransferase, including the free enzyme and complexes with S-adenosyl homocysteine (SAH), substrate, product, and unnatural substrates,more » show that SAM binding induces substantial ordering that creates the binding site for the natural substrate, and a bound metal ion positions the substrate for catalysis. A single amino acid substitution relaxed the 2'-methoxy specificity but retained regiospecificity. The engineered variant produced a new mycinamicin analog, demonstrating the utility of structural information to facilitate bioengineering approaches for the chemoenzymatic synthesis of complex small molecules containing modified sugars. Using the MycF substrate complex and the modeled substrate complex of a 4'-specific homolog, active site residues were identified that correlate with the 3'- or 4'- specificity of MycF family members and define the protein and substrate features that direct the regiochemistry of methyltransfer.

The early transcribed membrane proteins ETRAMPs belong to a family of small, transmembrane molecules unique to Plasmodium parasite, which share a signal peptide followed by a short lysine-rich stretch, a transmembrane domain and a variable, highly charged C-terminal region. ETRAMPs are usually expressed in a stage-specific manner. In the blood stages they localize to the parasitophorous vacuole membrane and, in described cases, to vesicle-like structures exported to the host erythrocyte cytosol. Two family members of the rodent parasite Plasmodium berghei, uis3 and uis4, localize to secretory organelles of sporozoites and to the parasitophorous membrane vacuole of the liver stages. By the use of specific antibodies and the generation of transgenic lines, we showed that the P. berghei ETRAMP family member SEP2 is abundantly expressed in gametocytes as well as in mosquito and liver stages. In intracellular parasite stages, SEP2 is routed to the parasitophorous vacuole membrane while, in invasive ookinete and sporozoite stages, it localizes to the parasite surface. To date SEP2 is the only ETRAMP protein detected throughout the parasite life cycle. Furthermore, SEP2 is also released during gliding motility of salivary gland sporozoites. A limited number of proteins are known to be involved in this key function and the best characterized, the CSP and TRAP, are both promising transmission-blocking candidates. Our results suggest that ETRAMP members may be viewed as new potential candidates for malaria control.

Compreender o relacionamento no quotidiano dos familiares acompanhantes nos cenários de cuidado que se aproximam da metáfora da tribo no ambiente hospitalar. Estudo qualitativo com dados coletados a partir de entrevistas semiestruturadas e observação com 16 familiares acompanhantes de pessoas hospitalizadas com dependência para o autocuidado. Os dados foram submetidos à análise temática e analisados através da metáfora da tribo proposta pela sociologia compreensiva. Os familiares formam um agrupamento social em torno do cuidado onde encontramos as características das tribos: a ambiência emocional; a solidariedade baseada nos vínculos de simpatia e ajuda mútua; a nebulosa afetual no processo interacional; a lógica da fusão nas relações tácteis e a comunhão/religiosidade no processo de ligação numa identidade coletiva. Os familiares na presença do trágico criam agrupamentos sociais que se assemelham a tribos cujo totem é o cuidado. Understand the quotidian relationships of accompanying family members in an environment of care, which are close to the metaphor of a tribe in hospital environment. METHODQualitative study with data gathered from semi-structured interviews and observations with 16 family members accompanying hospitalized individuals with dependence on self-care. Data were submitted to thematic analysis, and analyzed through the metaphor of "tribe" proposed by comprehensive sociology. Family members build up social clusters around caring, where we find traits typical of tribes: emotional ambience; solidarity based on links of sympathy and mutual assistance; an affectual nebula in the process of interaction; a logic of fusion in tactile relations; and communion/religiosity in the process of connecting in a collective identity. In the presence of tragedy, families build social clusters similar to tribes having care as a totem.

Peroxisome proliferators-activated receptor (PPAR) gene family members exhibit distinct patterns of distribution in tissues and differ in functions. The purpose of this study is to investigate the evolutionary impacts on diversity functions of PPAR members and the regulatory differences on gene expression patterns. 63 homology sequences of PPAR genes from 31 species were collected and analyzed. The results showed that three isolated types of PPAR gene family may emerge from twice times of gene duplication events. The conserved domains of HOLI (ligand binding domain of hormone receptors) domain and ZnF_C4 (C4 zinc finger in nuclear in hormone receptors) are essential for keeping basic roles of PPAR gene family, and the variant domains of LCRs may be responsible for their divergence in functions. The positive selection sites in HOLI domain are benefit for PPARs to evolve towards diversity functions. The evolutionary variants in the promoter regions and 3′ UTR regions of PPARs result into differential transcription factors and miRNAs involved in regulating PPAR members, which may eventually affect their expressions and tissues distributions. These results indicate that gene duplication event, selection pressure on HOLI domain, and the variants on promoter and 3′ UTR are essential for PPARs evolution and diversity functions acquired.

Little is known about communication between patients and their family members during critical illness and mechanical ventilation in the intensive care unit, including use of augmentative and alternative communication tools and strategies. To identify (1) which augmentative and alternative communication tools families use with nonspeaking intensive care patients and how they are used, and (2) what families and nurses say about communication of family members with nonspeaking intensive care patients. A qualitative secondary analysis was conducted of existing data from a clinical trial testing interventions to improve communication between nurses and intensive care patients. Narrative study data (field notes, intervention logs, nurses' interviews) from 127 critically ill adults were reviewed for evidence of family involvement with augmentative and alternative communication tools. Qualitative content analysis was applied for thematic description of family members' and nurses' accounts of patient-family communication. Family involvement with augmentative and alternative communication tools was evident in 44% of the 93 patients who completed the parent study protocol. Spouses or significant others communicated with patients most often. Main themes describing patient-family communication included (1) families being unprepared and unaware, (2) families' perceptions of communication effectiveness, (3) nurses deferring to or guiding patient-family communication, (4) patients' communication characteristics, and (5) families' experience with and interest in augmentative and alternative communication tools. Assessment by skilled bedside clinicians can reveal patients' communication potential and facilitate useful augmentative and alternative communication tools and strategies for patients and their families.

The objective of this study was to better understand the experiences of family members in the nursing home to hospital transfer decision making process. Semi-structured interviews were conducted with 20 family members who had recently been involved in a nursing home to hospital transfer decision. Family members perceived themselves to play an advocacy role in their resident's care and interview themes clustered within three over-arching categories: Family perception of the nursing home's capacity to provide medical care: Resident and family choices; and issues at 'hand-off' and the hospital. Multiple sub-themes were also identified. Findings from this study contribute to knowledge surrounding the nursing home transfer decision by illuminating the experiences of family members in the transfer decision process.

An HIV-infected patient was diagnosed with acute hepatitis E infection in our hospital. An epidemiological inquiry was performed to collect demographic, food and animal exposure variables in order to identify the potential route of transmission. The patient reported that his family traditionally hunted wild boar for food. All family members were analysed for hepatitis E virus infection. Additionally, route of transmission by wild boar meat consumption and prevalence of HEV infection among wild boar from the same hunting area were investigated. In all-family members (n = 8), HEV-RNA was amplified. Two wild boar meat slices consumed was analysed, showing the presence of HEV. The virus isolated was consistent with genotype 3, revealing 100% homology between family members and meat. Additionally, we tested nine wild boar hunted in the same hunting area. All of them were RNA-HEV positive, isolating the same HEV genotype 3 viral strain. We demonstrated by phylogenetic analysis zoonotic transmission of HEV by wild boar meat consumption. The prevalence of HEV infection among wild boar found in our study suggests that this species is an important route of transmission to human. © 2017 Blackwell Verlag GmbH.

Despite increased functionality for obtaining family history in a structured format within electronic health record systems, clinical notes often still contain this information. We developed and evaluated an Unstructured Information Management Application (UIMA)-based natural language processing (NLP) module for automated extraction of family history information with functionality for identifying statements, observations (e.g., disease or procedure), relative or side of family with attributes (i.e., vital status, age of diagnosis, certainty, and negation), and predication (“indicator phrases”), the latter of which was used to establish relationships between observations and family member. The family history NLP system demonstrated F-scores of 66.9, 92.4, 82.9, 57.3, 97.7, and 61.9 for detection of family history statements, family member identification, observation identification, negation identification, vital status, and overall extraction of the predications between family members and observations, respectively. While the system performed well for detection of family history statements and predication constituents, further work is needed to improve extraction of certainty and temporal modifications.

The Empirical Canadian High Arctic Ionospheric Model (E-CHAIM): NmF2 and hmF2 specification

It is well known that the International Reference Ionosphere (IRI) suffers reduced accuracy in its representation of monthly median ionospheric electron density at high latitudes (Themens et al. 2014, Themens et al. 2016). These inaccuracies are believed to stem from a historical lack of data from these regions. Now, roughly thirty and forty years after the development of the original URSI and CCIR foF2 maps, respectively, there exists a much larger dataset of high latitude observations of ionospheric electron density. These new measurements come in the form of new ionosonde deployments, such as those of the Canadian High Arctic Ionospheric Network, the CHAMP, GRACE, and COSMIC radio occultation missions, and the construction of the Poker Flat, Resolute, and EISCAT Incoherent Scatter Radar systems. These new datasets afford an opportunity to revise the IRI's representation of the high latitude ionosphere. For this purpose, we here introduce the Empirical Canadian High Arctic Ionospheric Model (E-CHAIM), which incorporates all of the above datasets, as well as the older observation records, into a new climatological representation of the high latitude ionosphere. In this presentation, we introduce the NmF2 and hmF2 portions of the model, focusing on both climatological and storm-time representations, and present a validation of the new model with respect to ionosonde observations from four high latitude stations. A comparison with respect to IRI performance is also presented, where we see improvements by up to 70% in the representation of peak electron density through using the new E-CHAIM model. In terms of RMS errors, the E-CHAIM model is shown to represent a near-universal improvement over the IRI, sometimes by more than 1 MHz in foF2. For peak height, the E-CHAIM model demonstrates overall RMS errors of 13km at each test site compared to values of 18-35km for the IRI, depending on location. Themens, D.R., P. T.

Structural and cultural changes in the care of older people have influenced nursing practice, creating a need to identify current competency requirements for nurses working in care homes. Family members have an important role in ensuring the well-being of older people living in care homes, and family members' can provide valuable information about competence requirements. To explore the expectations of the care home residents' family members regarding the competence of nurses in care homes for older people. A qualitative descriptive design was used. Semi-structured interviews were conducted with 18 care home residents' family members between March and September 2016. Participants were recruited with help from regional associations and member associations of The Central Association of Carers in Finland and from regional associations of The Alzheimer's Society of Finland. The snowball technique was also used. The data were analysed using inductive content analysis. Ethics committee approval was obtained from the university committee on research ethics, and written informed consent was obtained from participants. The care home residents' family members expected that nurses would be able to interact with and treat people respectfully. Reflective collaboration between the nurse and a family member was also emphasised. Family members expected nurses to provide high-quality basic care and nursing and support residents' well-being individually and holistically. Family members' expectations reflect the need for ethical and interactional competence in the care home. In addition, evidence-based practice competencies are required to provide high-quality care. Nurses' ability to provide person-centred, individual and holistic care is vital to ensure care home residents' well-being. © 2017 Nordic College of Caring Science.

Personal attributions for cancer risk involve factors that individuals believe contribute to their risk for developing cancer. Understanding personal risk attributions for melanoma may dictate gene-environment melanoma risk communication strategies. We examined attributions for melanoma risk in a population-based sample of melanoma survivors, first degree family members, and family members who are also parents (N=939). We conducted qualitative examination of open-ended risk attributions and logistic regression examining predictors (demographics, family member type, perceived risk) of the attributions reported (ultraviolet radiation [UVR] exposure, heredity/genetics, phenotype, personal melanoma history, miscellaneous). We found a predominance of risk attributions to UVR and heredity/genetics (80% and 45% of the sample, respectively). Those reporting higher education levels were more likely to endorse attributions to heredity/genetics, as well as to phenotype, than those of lower education levels. First-degree relatives and parent family members were more likely to endorse heredity/genetic attributions than melanoma survivors; melanoma survivors were more likely to endorse personal history of melanoma attributions compared to first-degree relatives and parent family members. These findings inform the development of risk communication interventions for melanoma families. PMID:20809355

Ternary complex (TC) and eIF4F complex assembly are the two major rate-limiting steps in translation initiation regulated by eIF2α phosphorylation and the mTOR/4E-BP pathway, respectively. How TC and eIF4F assembly are coordinated, however, remains largely unknown. We show that mTOR suppresses translation of mRNAs activated under short-term stress wherein TC recycling is attenuated by eIF2α phosphorylation. During acute nutrient or growth factor stimulation, mTORC1 induces eIF2β phosphorylation and recruitment of NCK1 to eIF2, decreases eIF2α phosphorylation and bolsters TC recycling. Accordingly, eIF2β mediates the effect of mTORC1 on protein synthesis and proliferation. In addition, we demonstrate a formerly undocumented role for CK2 in regulation of translation initiation, whereby CK2 stimulates phosphorylation of eIF2β and simultaneously bolsters eIF4F complex assembly via the mTORC1/4E-BP pathway. These findings imply a previously unrecognized mode of translation regulation, whereby mTORC1 and CK2 coordinate TC and eIF4F complex assembly to stimulate cell proliferation. PMID:27040916

Enzymes catalyzing the biosynthesis of bacterial peptidoglycan represent traditionally a collection of highly selective targets for novel antibacterial drug design. Four members of the bacterial Mur ligase family-MurC, MurD, MurE and MurF-are involved in the intracellular steps of peptidoglycan biosynthesis, catalyzing the synthesis of the peptide moiety of the Park's nucleotide. In our previous virtual screening campaign, a chemical class of benzene-1,3-dicarboxylic acid 2,5-dimethylpyrrole derivatives exhibiting dual MurD/MurE inhibition properties was discovered. In the present study we further investigated this class of compounds by performing inhibition assays on all four Mur ligases (MurC-MurF). Furthermore, molecular dynamics (MD) simulation studies of one of the initially discovered compound 1 were performed to explore its geometry as well as its energetic behavior based on the Linear Interaction Energy (LIE) method. Further in silico virtual screening (VS) experiments based on the parent active compound 1 were conducted to optimize the discovered series. Selected hits were assayed against all Escherichia coli MurC-MurF enzymes in biochemical inhibition assays and molecules 10-14 containing benzene-1,3-dicarboxylic acid 2,5-dimethylpyrrole coupled with five member-ring rhodanine moiety were found to be multiple inhibitors of the whole MurC-MurF cascade of bacterial enzymes in the micromolar range. Steady-state kinetics studies suggested this class to act as competitive inhibitors of the MurD enzyme towards d-Glu. These compounds represent novel valuable starting point in the development of novel antibacterial agents. Copyright © 2014 Elsevier Ltd. All rights reserved.
