Petty Passions, Nobler Actions, and Two Peculiar Institutions: Sectionalism, Partisanship, and the United States Senate, 1845-1850

The period from 1845-1850 was a critical moment in American history, as the question of the expansion of slavery into western territories battered the nation, turning a political system until then focused on issues of tariff and banking, to the decision of sectional and moral questions. Despite the emotion and danger of the time, the Senate, which ultimately decided the questions of slavery’s expansion, brokered the Compromise of 1850, a measure that stemmed the sectionalist fervor for a time. This was achieved only through the seasoned leadership and sacrifice of uniquely great American political leaders, overcoming complications of party and section. Nevertheless, the challenges to long-term national political health remained, leading to the Compromise’s undoing only four years later due to flaws evident during the period of its development and construction. The United States Senate, addressing the expansion of slavery from 1845-1850, failed to sufficiently resolve the growing moral, political, and ideological tension with the Compromise of 1850 because of the opposing sections, divided parties, separate generations, and conflicting leaders which characterized the body. This paper examines the institutional context of the Senate’s actions from 1845-1850, including the political party system, growing sectionalism, and the rise of a new generation of political leaders, from the perspective of the great Senators of the period, Henry Clay, Daniel Webster, John C. Calhoun, and Thomas Hart Benton. Quantitative analysis of voting patterns in the Senate during the period is mixed with qualitative research for insight into the Senate’s action and dynamics. Thus, a model of short-term sectionalism is arrived at illustrating why the Senate rejected some compromise plans and passed the Compromise if 1850, which was a short-term solution to the problem of slavery

Bridges and Bandits on the Road to the New Jerusalem: A Study of the Correlation Between Immigration and Terrorism

In late January of 2017, President Trump signed an executive order banning non-American citizens traveling into the United States from seven different countries. The title of the order was, “Protecting the Nation From Foreign Terrorist Entry Into the United States.” As implied, the stated purpose was to limit the number of immigrants in order to avoid future attacks. For the order to serve a purpose, immigration must play a role in terrorism. Thus, the essential point of disagreement is whether a connection exists between the influx of migrants—especially those from terror-prone nations—and the occurrence of terrorist activity in the receiving nation. In this study, we attempt to discover if a link exists between immigration from terror-prone nations and terrorism by examining the current literature and using data to analyze the levels of immigration as well as the incidents of terrorism in six countries. The hypothesis of this research project is that as countries receive increased levels of asylum seekers from terror-prone nations they will experience a corresponding increase in the numbers of terror attacks within the nation. Our basic premise is that immigrant flows form a social bridge, transplanting cultures, ideologies, as well as individuals between the sending and receiving nations. Thus, we are seeking to find out if there is a strong correlation between immigration and terrorism. The null hypothesis, then, is that there is no correlation between immigration from terror-prone nations and the occurrence of terror attacks within a particular nation. Our research shows that, as predicted in our hypothesis, increased terrorism is linked to increased migration from terror-prone nations and regions. The data from Germany and Turkey display a strong positive correlation between asylum-seeker migration and incidents of terrorism. It is worth noting that immigration alone is not enough to predict a rise in terrorist attacks. Rather, immigration is only one of many factors that may lead to increased terrorism. However, it is our contention that immigration from terror-producing regions is a significant predictor of increased terrorist activity

Veneziano Amplitudes, Spin Chains and String Models

In a series of recently published papers we reanalyzed the existing treatments of Veneziano and Veneziano-like amplitudes and the models associated with these amplitudes. In this work we demonstrate that the already obtained new partition function for these amplitudes can be exactly mapped into that for the Polychronakos-Frahm (P-F) spin chain model. This observation allows us to recover many of the existing string-theoretic models, including the most recent ones.Comment: 38 page

Effector cell mediated cytotoxicity measured by intracellular Granzyme B release in HIV infected subjects

CD8+ cytotoxic T lymphocyte (CTL) activity is currently believed to be one of the key immunologic mechanisms responsible for the prevention or attenuation of HIV-1 infection. The induction of CD8+ T cell activation may also result in the production of soluble or non-classical lytic factors that are associated with protection from infection or slower disease progression. Traditionally, CD8+ CTL responses have been measured by the classic chromium release assay, monitoring the ability of T cells (Effector cells) to lyse radiolabelled HLA – matched “target cells” that express the appropriate antigen-MHC complex. This method is not only labor intensive, semi quantitative assay at best, but also needs fresh, non-cryopreserved cells. Recently, cytokine specific ELISPOT assays or tetrameric MHC-I/ peptide complexes have utilized to directly quantitate circulating CD8+ effector cells, and these assays are more sensitive, quantitative and reproducible than the traditional CTL lysis assay and can also be performed on cryopreserved cells. Although these are reproducible assays for the assessment of soluble antiviral activity secreted by activated T cell populations they can be extremely expensive to perform. We have used FACS Analysis to measure Granzyme B release as a function of cell mediated cytotoxicity. This method helps quantitate the CTL activity and also identifies the phenotype of the cells elucidating this immune response. The method described not only monitors immunological response but also is also simple to perform, precise and extremely time efficient and is ideal for screening a large number of samples

Plasma proteome changes in cardiovascular disease patients: novel isoforms of apolipoprotein A1

<p>Abstract</p> <p>Background</p> <p>The aim of this proteomic study was to look for changes taking place in plasma proteomes of patients with acute myocardial infarction (AMI), unstable angina pectoris (UAP), and stable angina pectoris (SAP).</p> <p>Methods</p> <p>Depleted plasma proteins were separated by 2D SDS-PAGE (pI 4-7), and proteomes were compared using Progenesis SameSpots statistical software. Proteins were identified by nanoLC-MS/MS. Proteins were quantified using commercial kits. Apolipoprotein A1 was studied using 1D and 2D SDS-PAGE, together with western blotting.</p> <p>Results</p> <p>Reciprocal comparison revealed 46 unique, significantly different spots; proteins in 34 spots were successfully identified and corresponded to 38 different proteins. Discrete comparisons of patient groups showed 45, 41, and 8 significantly different spots when AMI, UAP, and SAP were compared with the control group. On the basis of our proteomic data, plasma levels of two of them, alpha-1 microglobulin and vitamin D-binding protein, were determined. The data, however, failed to prove the proteins to be suitable markers or risk factors in the studied groups. The plasma level and isoform representation of apolipoprotein A1 were also estimated. Using 1D and 2D SDS-PAGE, together with western blotting, we observed extra high-molecular weight apolipoprotein A1 fractions presented only in the patient groups, indicating that the novel high-molecular weight isoforms of apolipoprotein A1 may be potential new markers or possible risk factors of cardiovascular disease.</p> <p>Conclusion</p> <p>The reported data show plasma proteome changes in patients with AMI, UAP, and SAP. We propose some apolipoprotein A1 fractions as a possible new disease-associated marker of cardiovascular disorders.</p

Can We Really Prevent Suicide?

Every year, suicide is among the top 20 leading causes of death globally for all ages. Unfortunately, suicide is difficult to prevent, in large part because the prevalence of risk factors is high among the general population. In this review, clinical and psychological risk factors are examined and methods for suicide prevention are discussed. Prevention strategies found to be effective in suicide prevention include means restriction, responsible media coverage, and general public education, as well identification methods such as screening, gatekeeper training, and primary care physician education. Although the treatment for preventing suicide is difficult, follow-up that includes pharmacotherapy, psychotherapy, or both may be useful. However, prevention methods cannot be restricted to the individual. Community, social, and policy interventions will also be essentia

Results of soy-based meal replacement formula on weight, anthropometry, serum lipids & blood pressure during a 40-week clinical weight loss trial

BACKGROUND: To evaluate the intermediate-term health outcomes associated with a soy-based meal replacement, and to compare the weight loss efficacy of two distinct patterns of caloric restriction. METHODS: Ninety overweight/obese (28 < BMI ≤ 41 kg/m(2)) adults received a single session of dietary counseling and were randomized to either 12 weeks at 1200 kcal/day, 16 weeks at 1500 kcal/d and 12 weeks at 1800 kcal/d (i.e., the 12/15/18 diet group), or 28 weeks at 1500 kcal/d and 12 weeks at 1800 kcal/d (i.e., the 15/18 diet group). Weight, body fat, waist circumference, blood pressure and serum lipid concentrations were measured at 4-week intervals throughout the 40-week trial. RESULTS: Subjects in both treatments showed statistically significant improvements in outcomes. A regression model for weight change suggests that subjects with larger baseline weights tended to lose more weight and subjects in the 12/15/18 group tended to experience, on average, an additional 0.9 kg of weight loss compared with subjects in the 15/18 group. CONCLUSION: Both treatments using the soy-based meal replacement program were associated with significant and comparable weight loss and improvements on selected health variables

Applying unmixing to gene expression data for tumor phylogeny inference

<p>Abstract</p> <p>Background</p> <p>While in principle a seemingly infinite variety of combinations of mutations could result in tumor development, in practice it appears that most human cancers fall into a relatively small number of "sub-types," each characterized a roughly equivalent sequence of mutations by which it progresses in different patients. There is currently great interest in identifying the common sub-types and applying them to the development of diagnostics or therapeutics. Phylogenetic methods have shown great promise for inferring common patterns of tumor progression, but suffer from limits of the technologies available for assaying differences between and within tumors. One approach to tumor phylogenetics uses differences between single cells within tumors, gaining valuable information about intra-tumor heterogeneity but allowing only a few markers per cell. An alternative approach uses tissue-wide measures of whole tumors to provide a detailed picture of averaged tumor state but at the cost of losing information about intra-tumor heterogeneity.</p> <p>Results</p> <p>The present work applies "unmixing" methods, which separate complex data sets into combinations of simpler components, to attempt to gain advantages of both tissue-wide and single-cell approaches to cancer phylogenetics. We develop an unmixing method to infer recurring cell states from microarray measurements of tumor populations and use the inferred mixtures of states in individual tumors to identify possible evolutionary relationships among tumor cells. Validation on simulated data shows the method can accurately separate small numbers of cell states and infer phylogenetic relationships among them. Application to a lung cancer dataset shows that the method can identify cell states corresponding to common lung tumor types and suggest possible evolutionary relationships among them that show good correspondence with our current understanding of lung tumor development.</p> <p>Conclusions</p> <p>Unmixing methods provide a way to make use of both intra-tumor heterogeneity and large probe sets for tumor phylogeny inference, establishing a new avenue towards the construction of detailed, accurate portraits of common tumor sub-types and the mechanisms by which they develop. These reconstructions are likely to have future value in discovering and diagnosing novel cancer sub-types and in identifying targets for therapeutic development.</p
