Characterization of enhancer elements in the long terminal repeat of Moloney murine sarcoma virus

A series of recombinant molecules were constructed which direct the expression of the easily assayed gene chloramphenicol acetyltransferase. We have used these recombinants to show that the 73/72-base-pair tandem repeat unit from the Moloney murine sarcoma virus long terminal repeat shares a number of properties with the prototypic enhancer element, the simian virus 40 72-base-pair repeat. Specifically, the Moloney murine sarcoma virus sequence significantly enhances the level of gene expression at both 5' and 3' locations and in either orientation relative to the test gene. It is able to enhance gene activity both from its own promoter and from a heterologous (simian virus 40) promoter. The 73/72-base-pair subunits of the Moloney murine sarcoma virus enhancer differ in sequence by four nucleotides and also in the strength of their enhancer function. The promoter distal A repeat is at least three times as active as the promoter proximal B repeat in enhancing chloramphenicol acetyltransferase expression. Results of these studies also show that the enhancer sequence alone is unable to induce gene activity but requires other promoter elements, including a proximal GC-rich sequence and the Goldberg-Hogness box.
Epidural catheterization in cardiac surgery: the 2012 risk assessment.

AIMS AND OBJECTIVES The risk assessment of epidural hematoma due to catheter placement in patients undergoing cardiac surgery is essential since its benefits have to be weighed against risks, such as the risk of paraplegia. We determined the risk of the catheter-related epidural hematoma in cardiac surgery based on the cases reported in the literature up to September 2012. MATERIALS AND METHODS We included all reported cases of epidural catheter placement for cardiac surgery in web and in literature from 1966 to September 2012. Risks of other medical and non-medical activities were retrieved from recent reviews or national statistical reports. RESULTS Based on our analysis the risk of catheter-related epidural hematoma is 1 in 5493 with a 95% confidence interval (CI) of 1/970-1/31114. The risk of catheter-related epidural hematoma in cardiac surgery is similar to the risk in the general surgery population at 1 in 6,628 (95% CI 1/1,170-1/37,552). CONCLUSIONS The present risk calculation does not justify not offering epidural analgesia as part of a multimodal analgesia protocol in cardiac surgery.
Anemia and blood transfusion in trauma patients admitted to the intensive care unit.

BACKGROUND Anemia is a common occurrence in the intensive care unit (ICU). Although resuscitation, including the use of blood, is a mainstay of early treatment of trauma victims, the safety and efficacy of red blood cell (RBC) transfusion has come under scrutiny recently. The issue of blood use in critically injured patients requires evaluation. METHODS This was a post hoc analysis of a subset of trauma patients (> or =18 years in age) from a prospective, multicenter, observational, cohort study in the United States. Patients were enrolled within 48 hours after ICU admission and followed for up to 30 days, or until hospital discharge or death. RESULTS Five hundred seventy-six patients from 111 ICUs in 100 hospitals were enrolled between August 2000 and April 2001. At baseline, mean age was 44.1 +/- 20.2 years, 73.6% were men, and mean APACHE II score was 16.9 +/- 8.2. Mean baseline hemoglobin was 11.1 +/- 2.4 g/dL and patients remained anemic throughout the study either with or without transfusion; 55.4% of patients were transfused (mean, 5.8 +/- 5.5 units) during the ICU stay and 43.8% of patients had an ICU length of stay > or = 7 days. Mean pretransfusion hemoglobin was 8.9 +/- 1.8 g/dL. Mean age of RBCs transfused was 20.1 +/- 11.4 days. As compared with the full study population, patients in the trauma subset were more likely to be transfused and received an average of 1 additional unit of blood. CONCLUSION Anemia is common in critically injured trauma patients and persists throughout the duration of critical illness. These patients receive a large number of RBC transfusions during their ICU course with aged blood.
Running head : STABILITY OF PERSONALITY Stability of Personality Traits in Adulthood : Mechanisms and Implications

Stability represents a fundamental concept in developmental theory and research. In this article we give an overview of recent work on personality traits and their stability in adulthood. First, we define personality traits and stability. Second, we present empirical evidence supporting change and stability of personality traits across the adult years with respect to conceptually and statistically different forms of stability. Third, we describe mechanisms and processes that enable trait stability. Finally, we discuss implications of trait stability for theory, research, and application.

The association between parental life history and offspring phenotype in Atlantic salmon

ABSTRACT In many taxa there is considerable intraspecific variation in life history strategies from within a single population, reflecting alternative routes through which organisms can achieve successful reproduction. Atlantic salmon Salmo salar (Linnaeus) show some of the greatest within-population variability in life history strategies amongst vertebrates, with multiple discrete male and female life histories co-existing and interbreeding on many spawning grounds, although the effect of the various combinations of life histories on offspring traits remains unknown. Using crosses of wild fish we show here that the life history strategy of both parents was significantly associated with a range of offspring traits. Mothers that had spent longer at sea (2 versus 1 year) produced offspring that were heavier, longer and in better condition at the time of first feeding. However, these relationships disappeared shortly after fry had begun feeding exogenously. At this stage, the juvenile rearing environment (i.e. time spent in fresh water as juveniles) of the mother was a better predictor of offspring traits, with mothers that were faster to develop in fresh water (migrating to sea after two rather than three years of age) producing offspring that had higher maximal metabolic rates, aerobic scopes, and that grew faster. Faster developing fathers (1 year old sneaker males) tended to produce offspring that had higher maximal metabolic rates, were in better body condition and grew faster. The results suggest that both genetic effects and those related to parental early and late life history contribute to offspring traits. Summary: The duration of early and later life stages of both parents (i.e. their life history) may have a significant influence on offspring traits in salmon.
Equine Infectious Anemia Virus Resists the Antiretroviral Activity of Equine APOBEC3 Proteins through a Packaging-Independent Mechanism

ABSTRACT Equine infectious anemia virus (EIAV), uniquely among lentiviruses, does not encode a vif gene product. Other lentiviruses, including human immunodeficiency virus type 1 (HIV-1), use Vif to neutralize members of the APOBEC3 (A3) family of intrinsic immunity factors that would otherwise inhibit viral infectivity. This suggests either that equine cells infected by EIAV in vivo do not express active A3 proteins or that EIAV has developed a novel mechanism to avoid inhibition by equine A3 (eA3). Here, we demonstrate that horses encode six distinct A3 proteins, four of which contain a single copy of the cytidine deaminase (CDA) consensus active site and two of which contain two CDA motifs. This represents a level of complexity previously seen only in primates. Phylogenetic analysis of equine single-CDA A3 proteins revealed two proteins related to human A3A (hA3A), one related to hA3C, and one related to hA3H. Both equine double-CDA proteins are similar to hA3F and were named eA3F1 and eA3F2. Analysis of eA3F1 and eA3F2 expression in vivo shows that the mRNAs encoding these proteins are widely expressed, including in cells that are natural EIAV targets. Both eA3F1 and eA3F2 inhibit retrotransposon mobility, while eA3F1 is a potent inhibitor of a Vif-deficient HIV-1 mutant and induces extensive editing of HIV-1 reverse transcripts. However, both eA3F1 and eA3F2 are weak inhibitors of EIAV. Surprisingly, eA3F1 and eA3F2 were packaged into EIAV and HIV-1 virions as effectively as hA3G, although only the latter inhibited EIAV infectivity. Moreover, all three proteins bound both the HIV-1 and EIAV nucleocapsid protein specifically in vitro. It therefore appears that EIAV has evolved a novel mechanism to specifically neutralize the biological activities of the cognate eA3F1 and eA3F2 proteins at a step subsequent to virion incorporation.
Exploring Impact of Macro Economic Variables on GDP of Pakistan

India gained her independence from British rule in August 1947, and her Constitution came into force in January 1950. These important events opened up a new page in the history of Indian state development, and also ushered onto the world stage a defining era of decolonization. Moreover, India was amongst the first colonies to endorse the so-called "civilized divorce" from her former colonial power, which promoted the smooth and gradual shift towards her sovereign status. Therefore, the events, which ultimately led to Indian independence and the formation of the post-colonial state, have been previously documented by historians of various schools of Indian history in different parts of the world. The present paper will discuss the formation process of Indian state sovereignty during 1947-1950, as it had been imagined, studied, and constructed by Soviet historians. It is important to study this issue in the light of Soviet historiography in order to recognize this interpretation of the past as an example of the relationship between history-writing the ruling government ideology. In addition to providing a detailed analysis of Soviet historiography on the status of post-colonial Indian state formation and sovereignty, this paper seeks to identify key moments in the development of Soviet history-writing in the post-war period, which can be useful in helping us to discern some of the main themes and intricacies of Indian state formation from a Soviet perspective.
Assessment of methods for measuring social support.

A rapidly expanding literature documents the effects of social support on physical and psychological well-being. Although definitions vary, most include both tangible components (e.g., financial assistance and physical aid) and intangible components (e.g., encouragement and guidance). Social support has been implicated in the mediation of stressful life events, recovery from illness, and increased program adherence. There are many inconsistent findings in the literature, however, and it is difficult to resolve discrepancies because measures of social support vary widely from study to study. To guide in the selection of measurement methods for research and applied work, 23 techniques for assessing social support are reviewed and evaluated. Criteria for favorable evaluation included reliability coefficients greater than . 8 and documentation of validity. Correlations between various social support and criterion measures are simulated in order to demonstrate the consequences of choosing a measure with low reliability. Scale developers reported reliability data for 19 of the reviewed measures. Internal consistency coefficients ranged from . 31 to . 98. Test-retest coefficients ranged from . 22 to . 96. At least some validity documentation was available for 13 of the scales. Discriminant validity evidence, however, is almost universally absent. Despite psychometric weaknesses and variability among the scales, researchers have several instruments available to them.
Party convergence and vote switching: Explaining mainstream party decline across Europe

How can one explain the significant vote losses of mainstream parties across Europe in recentyears? In this article, it is argued that mainstream party convergence is an important determinant of therecent political and electoral volatility in European party systems. More specifically, it is hypothesised thatas mainstream parties converge on the left-right scale,voters will switch from supporting a mainstream partyto a non-mainstream party in the next election as they look for an alternative that better represents theirideological views. To test these theoretical expectations, data is combined from the Comparative Studyof Electoral Systems and the Manifestos Project for nearly 15,000 vote choices of individual voters in30 elections in 16 West and East European countries from 2001 until 2013. The findings have importantimplications for understanding the recent rise of non-mainstream parties, the changing nature of partysystems and the increasing complexity of cabinet formation across Europe.
Lyophilization decreases the formation of dialyzable iron by extraction and digestion of chicken breast muscle

We studied the effect of lyophilization of chicken breast muscle on the formation of dialyzable iron from ferric iron. Chicken breast muscle was used chilled, frozen or lyophilized and was analyzed for sulfhydryl and histidine content. It was then homogenized and mixed with ferric iron. The mixture was extracted with acid or digested with pepsin and pancreatin. The extracts and digests were analyzed for dialyzable ferrous and dialyzable total iron and also for protein. In the chilled muscle, similar amounts of dialyzable iron were formed after acid extraction and after proteolytic digestion; however, digestion led to more dialyzable ferrous iron. Freezing had no effect but lyophilization of the homogenized muscle caused large decreases in dialyzable iron and dialyzable ferrous iron for both extraction and digestion processes. Lyophilization also resulted in decreased extraction of peptides, decreased digestion of muscle proteins and reduced levels of sulfhydryl and histidine residues. Our results demonstrate that dialyzable iron is produced both by acid-soluble low molecular weight muscle component(s) and also by peptides resulting from digestion of muscle proteins: both of which reduce and chelate iron. Reduced formation of dialyzable iron by both mechanisms following lyophilization could be explained by sulfhydryl oxidation and impaired digestion due to protein crosslinking.
A Skeptical Note on the Role of Constant Elasticity of Substitution in Labor Income Share Dynamics

The constancy of the elasticity of factor substitution (σ) makes its role as a driver of the labor income share exogenous. The constant elasticity of substitution (CES) production function has predominantly been used to support this causal relationship. We argue that (i) capital-labor ratio determines the value of σ, and (ii) both capital-labor ratio and σ vary over time. We use a variable elasticity of substitution (VES) production framework that allows both labor income share and σ to change over time. Statistically significant empirical support is provided using the Japanese industrial productivity data. This suggests that the CES model may not be an ideal choice to examine the factor income share dynamics.
TNF-alpha contributes to the development of allergic rhinitis in mice.

BACKGROUND Allergic rhinitis is an inflammation involving T(H)2-type cytokine production, with pathologic eosinophil infiltration in the nasal mucosa. Although TNF-alpha is thought to be a pro-inflammatory cytokine, the relationship between TNF-alpha and allergic rhinitis has not been clarified. OBJECTIVES The role of TNF-alpha in a murine model of ovalbumin (OVA)-sensitized allergic rhinitis was investigated by using mice deficient in the gene encoding TNF-alpha (TNF-alpha(-/-) mice). METHODS Both wild-type (TNF-alpha(+/+)) and TNF-alpha(-/-) mice were sensitized with OVA by means of intraperitoneal injection. They were then challenged with intranasal OVA, and various allergic responses were assessed. RESULTS The production of OVA-specific IgE in the serum (P <.05) and the frequency of sneezes (P <.05) and nasal rubs (P <.05) decreased significantly in TNF-alpha(-/-) mice after OVA sensitization compared with that in TNF-alpha(+/+) mice (P <.05). The mRNA expression of IL-4, IL-10, and eotaxin in nasal mucosa in TNF-alpha(-/-) mice was also significantly suppressed compared with that in TNF-alpha(+/+) mice after OVA sensitization (P <.05). Furthermore, the expression of both endothelial-leukocyte adhesion molecule 1 and vascular cell adhesion molecule 1 mRNA in the nasal mucosa was significantly suppressed (P <.05), although intercellular adhesion molecule 1 mRNA expression did not decrease significantly in TNF-alpha(-/-) mice compared with that in TNF-alpha(+/+) mice after OVA sensitization. In addition, the effect of TNF-alpha on endothelial-leukocyte adhesion molecule 1 and vascular cell adhesion molecule 1 expression by means of Western blot analysis was compatible with the mRNA results. Pathologically, eosinophil infiltration in nasal mucosa was significantly restricted in TNF-alpha(-/-) mice compared with in TNF-alpha(+/+) mice after OVA sensitization (P <.05). CONCLUSION TNF-alpha is necessary for antigen-specific IgE production and for the induction of T(H)2-type cytokines and chemokines. Furthermore, TNF-alpha might be important for the expression of adhesion molecules to recruit eosinophils to the allergic inflammatory site. We conclude that the lack of TNF-alpha inhibited the development of allergic rhinitis.
Characterization and Functional Analysis of 4-Coumarate:CoA Ligase Genes in Mulberry

A small, multigene family encodes 4-coumarate:CoA ligases (4CLs) that catalyze the ligation of CoA to hydroxycinnamic acids, a branch point directing metabolites to flavonoid or monolignol pathways. In this study, we characterized four 4CL genes from M. notabilis Genome Database, and cloned four Ma4CL genes from M. atropurpurea cv. Jialing No.40. A tissue-specific expression analysis indicated that Ma4CL3 was expressed at higher levels than the other genes, and that Ma4CL3 was strongly expressed in root bark, stem bark, and old leaves. Additionally, the expression pattern of Ma4CL3 was similar to the trend of the total flavonoid content throughout fruit development. A phylogenetic analysis suggested that Mn4CL1, Mn4CL2, and Mn4CL4 belong to class I 4CLs, and Mn4CL3 belongs to class II 4CLs. Ma4CL genes responded differently to a series of stresses. Ma4CL3 expression was higher than that of the other Ma4CL genes following wounding, salicylic acid, and ultraviolet treatments. An in vitro enzyme assay indicated that 4-coumarate acid was the best substrate among cinnamic acid, 4-coumarate acid, and caffeate acid, but no catalytic activity to sinapate acid and ferulate acid. The results of subcellular localization experiments showed that Ma4CL3 localized to the cytomembrane, where it activated transcription. We used different vectors and strategies to fuse Ma4CL3 with stilbene synthase (STS) to construct four Ma4CL-MaSTS co-expression systems to generate resveratrol. The results indicated that only a transcriptional fusion vector, pET-Ma4CL3-T-MaSTS, which utilized a T7 promoter and lac operator for the expression of MaSTS, could synthesize resveratrol.
Gene expression in peri‐implant crevicular fluid of smokers and nonsmokers. 1. The early phase of osseointegration

BACKGROUND Smoking is a risk factor for dental implants. The mechanisms behind the impact of smoking on osseointegration are not fully understood. PURPOSE To investigate the initial molecular and clinical course of osseointegration of different titanium implants in smokers and nonsmokers. MATERIALS AND METHODS Smoker (n = 16) and nonsmoker (n = 16) patients were included. Each patient received three implant types: machined, oxidized and laser-modified surfaces. After 1, 7, 14, and 28 days, the peri-implant crevicular fluid (PICF) was sampled for gene expression analysis of selected factors involved in early processes of osseointegration. Furthermore, pain-score (VAS), resonance frequency analysis (RFA) and baseline clinical assessments were performed. RESULTS Early failure of osseointegration, associated with a high and sustained perception of pain, was encountered in 3/32 patients. In general, high pain scores were reported during the first days after implantation, irrespective to smoking habit, which correlated to high levels of pro-inflammatory cytokines during the first days after implantation. Higher ISQ values were found in smokers compared to nonsmokers. In smokers exclusively, ISQ values correlated to harder and less atrophic bone quality and quantity, respectively. Smokers displayed a higher expression of osteocalcin (OC), but later peak and lower expression of bone morphogenetic protein (BMP-2) (at 7 days) compared to nonsmokers. In comparison to machined implants, surface-modified implants were associated with higher expression of alkaline phosphatase (ALP) and cathepsin K (CatK) at 28 days in nonsmokers. CONCLUSIONS During the early phase of osseointegration, postoperative pain is linked to the inflammatory cell response and, may tentatively serve as an indicator of biological complication and implant loss. The present study suggests that smokers have an altered bone composition and (ultra)structure based on the observations that ISQ values are higher and correlate to recipient bone quality and quantity in smokers.
Adult liver transplantation: An analysis of the early causes of death in 40 consecutive cases

One hundred twenty‐nine adult patients who received an orthotopic liver transplantation and survived at least 24 hr after surgery were evaluated. During the period of follow‐up, 48 of the 129 patients (37%) died. Only 40 of these 48 patients died at our institution and were included in this study. Seventeen of the 40 deaths (42.5%) occurred during the first month after orthotopic liver transplantation and 30 of the 40 deaths (75%) occurred during the first 60 days post‐orthotopic liver transplantation. Death was related to infection in 21 cases (52.5%), to multiorgan failure in 8 (20%) and to uncontrollable rejection in 3 (7.6%). The remaining eight deaths (20%) were attributed to a variety of other causes. Eleven of the 21 deaths related to infection (52%) occurred during the first month after orthotopic liver transplantation. Bacterial sepsis was the leading cause of death and accounted for 17 of the 21 deaths (81%) in which infection was present at the time of death. The most frequently isolated bacteria were Pseudomonas and other enteric Gram‐negative bacilli. Three patients had complete occlusion of the hepatic artery of the grafted liver. Six patients developed massive infarction of the liver despite patent vascular anastomoses. Histological signs of rejection were seen in 9 of the 31 patients autopsied (29%), but in only 3 of these (9.6%) was rejection the principal cause of death. The biliary anastomoses were patent in all 31 cases examined at autopsy.
