#1
Biel Roig-Solvas, Lee Makowski
An alternate formulation of helical diffraction theory is used to generate cross-sectional shapes of fibrous structures from equatorial scattering. We demonstrate this approach with computationally generated scattering intensities and then apply it to scattering data from Tobacco Mosaic Virus (TMV) and in vitro assembled fibrils of Aβ40 peptides. Refining the cross-sectional shape of TMV from SAXS data collected on a 26 mg/ml solution resulted in a circular shape with outer diameter of ∼ 180Å and inner diameter of ∼ 40Å consistent with the known structure of TMV...

In 1955, Eugene Garfield (1925-1917) published a paper in Science where for the first time he advocated the necessity of introducing parameters to assess the quality of scientific journals. Underlying this necessity was an observation of a trend where the whole area of influence in academic publishing was dominated by a narrow group of large interdisciplinary research journals. For this reason, along with Irving H. Sher, they created the impact factor (IF), also called the Garfield impact factor, journal citation rate, journal influence, and journal impact factor...

Between 5 and 8 million people globally are infected with Trypanosoma cruzi, the causative parasitic agent of Chagas disease. The vast majority of incident infections originate in pockets of Latin America where domestic vector-borne transmission cycles are more common. Since 1955, when the first locally-acquired case was reported, fewer than 30 autochthonous cases have been documented in the United States. We describe the case of an 18-year-old US Air Force trainee, a native Texan with no travel history beyond the continental United States, who screened positive for T cruzi infection on blood donation and was subsequently found to have chronic Chagasic cardiomyopathy...

REVIEW
Klaas R Westerterp
The doubly labelled water method for the assessment of energy expenditure was first published in 1955, application in humans started in 1982, and it has become the gold standard for human energy requirement under daily living conditions. The method involves enriching the body water of a subject with heavy hydrogen ((2)H) and heavy oxygen ((18)O), and then determining the difference in washout kinetics between both isotopes, being a function of carbon dioxide production. In practice, subjects get a measured amount of doubly labelled water ((2)H 2(18) O) to increase background enrichment of body water for (18)O of 2000 ppm with at least 180 ppm and background enrichment of body water for (2)H of 150 ppm with 120 ppm...

BACKGROUND: The use of complementary and alternative medicine (CAM) is growing. However the factors contributing to changes over time and to birth cohort differences in CAM use are not well understood. SETTING: We used data from 10186 participants, who were aged 20-69 years at the first cycle of data collection in the longitudinal component of the Canadian National Population Health Survey (1994/95-2010/11). We examined chiropractic and other practitioner-based CAM use with a focus on five birth cohorts: pre-World War II (born 1925-1934); World War II (born 1935-1944); older baby boomers (born 1945-1954); younger baby boomers (born 1955-1964); and Gen Xers (born 1965-1974)...

Ulrike Enke, Aeka Ishihara
The heart of this article is the transmission of selected chapters from the Japanese bacteriologist Taichi Kitashima's (1870-1956) autobiographical memoirs (in Japanese, Jiden) published in 1955, in which Kitashima reports on his stay in Marburg in a very personal and subjective way. Like other Japanese physicians of his generation, Kitashima spent several years in Germany in order to work with the serum researcher Emil von Behring and continued his education there. The contact came through Kitashima's teacher Shibasaburô Kitasato, who had worked with Behring in Berlin on questions of immunology...

BACKGROUND: One potential concern with using mailed surveys containing trauma-related content is the possibility of re-traumatizing survivors without a trained mental health professional present. Prior research provides insufficient guidance regarding the prevalence and magnitude of this risk because the psychological harms of trauma-related surveys have typically been estimated using single post-test observations. Post-test observations cannot quantify magnitude of change in participants' emotional states and may over or under estimate associations between participants' characteristics (risk factors) and post-survey upset...

BACKGROUND: Survivors of childhood cancer are at increased risk for a wide range of late effects. However, no large population-based studies have included the whole range of somatic diagnoses including subgroup diagnoses and all main types of childhood cancers. Therefore, we aimed to provide the most detailed overview of the long-term risk of hospitalisation in survivors of childhood cancer. METHODS AND FINDINGS: From the national cancer registers of Denmark, Finland, Iceland, and Sweden, we identified 21,297 5-year survivors of childhood cancer diagnosed with cancer before the age of 20 years in the periods 1943-2008 in Denmark, 1971-2008 in Finland, 1955-2008 in Iceland, and 1958-2008 in Sweden...

Several noncardiac drugs have been linked to cardiac safety concerns, highlighting the importance of post-marketing surveillance and continued evaluation of the benefit-risk of long-established drugs. Here, we examine the risk of QT prolongation and/or torsade de pointes (TdP) associated with the use of hydroxyzine, a first generation sedating antihistamine. We have used a combined methodological approach to re-evaluate the cardiac safety profile of hydroxyzine, including: (1) a full review of the sponsor pharmacovigilance safety database to examine real-world data on the risk of QT prolongation and/or TdP associated with hydroxyzine use and (2) nonclinical electrophysiological studies to examine concentration-dependent effects of hydroxyzine on a range of human cardiac ion channels...

Thomas Mann (1875-1955), a Nobel Prize recipient rightly considered one of the great novelists of the twentieth century, was one of the most medically perceptive writers of recent times. His novels take place against the background of the different plagues (tuberculosis, cholera) that characterized the eighteenth and nineteenth centuries. One of Mann's later novels, Doctor Faustus, is set against a background of syphilis. In the 500-page book, which is subtitled The Life of the German Composer Adrian Leverkühn as told by a Friend, we see the theologian turned composer make a pact with the devil...

Viruses are the most abundant biological entities on Earth and can be found in a variety of environments. A high prevalence of viruses in marine and freshwater systems was initially reported by Spencer in 1955, but the ecological significance of viruses is insufficiently known even until the present day. Viruses are known to play a key role in the biology of freshwater bacteria: controlling the bacterial abundance, composition of species, and acting as intermediaries in the transfer of genes between bacterial populations...

Cognitive disorders common in the post-operative period, are the post-operative delirium (POD) and the post-operative cognitive dysfunction (POCD). The Diagnostic and Statistical Manual of Mental Disorders (DSM) does not mention POCD as a separate disease entity, and thus little is known about the pathogenesis of this disorder. The aim of this study was to review, detect and highlight the most important data cited, regarding pathogenesis mechanisms and treatment of the post-operative cognitive dysfunction (POCD)...

BACKGROUND: Brucellosis was a common human and livestock disease caused by Brucella strains, the category B priority pathogens by the US Center for Disease Control (CDC). Identified as a priority disease in human and livestock populations, the increasing incidence in recent years in China needs urgent control measures for this disease but the molecular background important for monitoring the epidemiology of Brucella strains at the national level is still lacking. METHODS: A total of 600 Brucella isolates collected during 60 years (from 1953 to 2013) in China were genotyped by multiple locus variable-number tandem repeat analysis (MLVA) and the variation degree of MLVA11 loci was calculated by the Hunter Gaston Diversity Index (HGDI) values...

Verbeekite, a monoclinic polymorph of PdSe2, was reported for the first time in 2002 by Roberts et al. The mineral has been discovered in the Musonoi Cu-Co-Mn-U mine, Democratic Republic of Congo, and was named after Dr. Théodore Verbeek, the first geoscientist who studied the palladium mineralization there (1955-1967). Until today, the crystal structure of this very rare mineral has been unknown. By syntheses via multianvil high-pressure/high-temperature methods at 11.5 GPa and 1300 °C, synthetic verbeekite could be obtained in a high degree of purity and comparatively good crystal quality, which made it possible to determine the full crystal structure for PdSe2 verbeekite from single-crystal X-ray diffractometer data: I2/a, a = 671...

In this study, we isolated a virus strain (YN12031) from specimens of Armigeres subalbatus collected in the China-Laos border. BHK-21 cells infected with YN12031 exhibited an evident cytopathic effect (CPE) 32 h post-infection. The virus particles were spherical, 70 nm in diameter, and enveloped; they also featured surface fibers. Molecular genetic analysis revealed that YN12031 was closely related to alpha viruses such as Chikungunya virus and Sindbis virus, and located in the same clade as MM2021, the prototype of Getahvirus (GETV) isolated in Malaysia in 1955...
