    Behavioral and Epidemiological factors behind Vaccine Hesitancy in The United States

    Get PDF
    Vaccines are by far the most significant achievement in public health over the last century, saving millions of lives. Vaccination provides immunity as well as protection against certain infectious diseases, and the majority of vaccines contain a weakened version of a disease-causing microorganism. But why do people continue to be skeptical of vaccines and what they can do to improve their health? Vaccines, in general, can evoke strong biological, cultural, social, and political reactions all over the world, not just in the United States. Vaccine history is extremely complex, and it is still ongoing today as new diseases emerge. The anti-vaccine movement has existed since the development of vaccines by Edward Jenner in 1796. It is critical to understand the past and continue building on what we know today through new vaccine research & technology. Diseases today are far more complex than in the past, but advances in technology have enabled us to combat diseases in ways we could never have imagined. The war on diseases is never-ending and will continue as long as humans exist. But why are people becoming more hesitant to get vaccinated than ever before, or refusing to get vaccinated at all? Today, the ongoing pandemic and the new COVID-19 vaccine are the main topics on which vaccines are being discussed in major news outlets. Many people have turned to the vaccine to protect themselves from the virus, but many are still skeptical that the vaccine is safe or effective. This has pushed vaccine hesitancy to the forefront of the pandemic, and it has become a hot topic not only in the United States but in countries all over the world

    Effect of Combined Drug Therapy and Genetic Modifiers on Hepatosteatosis and Fibrosis in a Mouse Model for Alström Syndrome

    Alström Syndrome (ALMS) is a genetic disorder characterized by obesity, progressive hearing and vision loss, and insulin resistance in humans. Variability of additional phenotypes exists among patients, often complicating diagnosis of ALMS (Marshall et al., 2011). Postmortem studies of patients with ALMS revealed severe fibrosis in multiple organs (Marshall et al., 2011). Currently, there are no known treatments for the fibrosis observed in ALMS patients. The purpose of the studies described herein was to examine the effects of losartan, an antifibrotic drug, on fibrogenesis and to identify genomic loci that modify ALMS phenotypes in a mouse model for ALMS (Alms1Gt/Gt). A genome wide screen performed in two backcrosses to C57BL/6Ei and Balb/cJ mouse strains identified two genetic modifiers in Alms1Gt/Gt mice. A significant quantitative trait locus (QTL) for high density lipoproteins (HDL) was identified on chromosome 5 in the backcross to C57BL/6Ei while significant modifying loci for retinal degeneration was identified on chromosome 2 in the backcross to Balb/cJ. Further analysis with additional progeny may reveal other significant modifiers. Histological and chemical analyses of samples from 24-week-old mutant and control mice treated with losartan were initiated in this study. The results of this study may help future therapeutic strategies for treating human patients with ALMS

    On a non-referential theory of meaning for simple names based on Ajdukiewicz's theory of meaning

    Get PDF
    In 1931-1934 Kazimierz Ajdukiewicz formulated two versions of the theory of meaning (A1 and A2). Tarski showed that A2 allows for synonymous names existing with different denotations. Tarski and Ajdukiewicz found that this feature disparages the theory. The force of Tarski's argument rests on the assumption that none of an adequate theory of meaning allows for synonymous names existing with different denotations. In the first part of this paper we present an appropriate fragment of A2 and Tarski's argument. In the second part we consider an elementary, interpreted language in which individual constants occur, but not functional symbols. For such a language we define semantically a relation of synonymity for simple names and show that it fulfills syntactical conditions formulated by Ajdukiewicz in A2 and allows for synonymous names with different denotations

    The title mol­ecule, C13H17ClN3OS+·Br−, consists of benzene and pyrrolidine rings and an S–C(NHCH3)2 group. The central C—N bond lengths in the S–C(NHCH3)2 fragment indicate partial double-bond character. Mol­ecules are inter­connected into chains by N—H⋯Br hydrogen bonds and the chains are linked into pairs by weak C—H⋯Br hydrogen bonds

    In the title molecular salt, C11H13ClN3OS+·Br−, the C—N bond lengths in the –S–C(NH2)2 fragment indicate partial double-bond character of these bonds. The constituent ions are connected by N—H⋯Br bridges into Z-shaped chains. The supra­molecular architecture of the structure can be described by being composed of these chains inter­locked by additional C—H⋯Br short contacts. An intra­molecular N—H⋯O=C bridge, as well as weak C—H⋯O hydrogen bonds, are also present in the structure
