Early Modern English Scientific Manuscripts in the Hunterian Collection: A Physical Description of Gul, MS Hunter 135
2017
RESUMEN: El presente artículo ofrece un análisis codicológico y paleográfi co del manuscrito Hunter 135, un volumen del siglo XVI que contiene cinco tratados de los cuales el segundo y la mitad del tercero son objeto de estudio (chirvrgia libri, ff. 34r-73v; y medica qvaedam, ff. 74r-121v). La descripción física no solo ha permitido aportar la posible fecha de composición del manuscrito sino que también ha hecho posible el análisis de las técnicas en la producción de manuscritos en el Periodo moderno temprano (1500-1700).ABSTRACT: The present article provides a codicological and palaeographic analysis of MS Hunter 135, a sixteenth-century volume containing fi ve treatises, the second and appr…
Desire and its preternse: Analysis of Intersubjective relations in Frank Capra's It happened one night
2019
The following paper analyzes the plot of the 1934 film It Happened One Night, by Frank Capra, an authentic emblem within the film genre of romantic comedy. In it, the protagonists manage to overcome the obstacles that are offered in their way thanks to the pretense of a relationship, the marital one, which finally will end up becoming effective. Recalling a famous Lacanian sentence, according to which human beings “pretend to pretend”, the plot devised by Capra will be analyzed in order to go over the steps that sequence such pretenses. These give order to a process of maturity in which the characters will become what they represent, evidencing the sexual nature of the desire that had impel…
Data from: When earwig mothers do not care to share: parent-offspring competition and the evolution of family life
2018
1. Kin competition often reduces – and sometimes entirely negates – the benefits of cooperation among relatives, and hence is often regarded as central process in social evolution. Surprisingly, however, our understanding of the role of kin competition in the evolution of family life remains fragmentary, despite the close scrutiny it received in studies on sibling rivarly. This is because much less attention has been given to local competition between parents and their offspring, and its potential impact on the early evolution of parental care and family life. 2. Here, we examined mother-offspring competition over food access in the European earwig Forficula auricularia, an insect with facu…
MRI of inner ear fluids using modified GRASS sequences: a useful tool in the assessment of the normal and pathological labyrinth
1995
MRI is acquiring a progressively more important role in the investigation of petrous bone disease. Nevertheless, despite the extensive use of MRI in the detection of inflammatory or neoplastic involvement of the seventh and eighth cranial nerves, conventional spinecho images cannot be considered the modality of choice in inner ear imaging “Steady-state sequences” are known to be motion sensitive. By setting a very short repetition time, a large flip angle and a long echo time, one can obtain a sequence sufficiently sensitive to the slow movement of endo- and perilymph. We report our experience in MRI of normal and pathological inner ear with modified GRASS sequences.
Hapten Design and Antibody Generation for Immunoanalysis of Spirotetramat and Spirotetramat-enol
2018
Spirotetramat - a tetramic acid insecticide - is rapidly metabolized or degraded to give spirotetramat-enol; so, common residue definitions include the sum of both compounds. In the present study, two spirotetramat-functionalized derivatives (haptens) have been designed to generate immunoreagents to these molecules for rapid immunochemical analysis. Haptens have been synthesized with alternative linker tethering sites and, for the first time, high-affinity antibodies have been generated with different specificities to these active principles. Two sensitive assays have been developed using the same antibody in different formats, and by using linker-site heterologous haptens, the selectivity …
MRI of the inner ear: use of modified GRASS and fast spin-echo sequences
1996
We report our experience with MRI of the normal and pathological inner ear with fast spin-echo and modified gradient recalled at steady state sequences. Although earlier studies on temporal bone MRI were discouraging, improvements in MR technology combined with the use of paramagnetic contrast media can make MRI a useful diagnostic tool for the assessment of inner ear pathology. Conventional spin-echo imaging seems not to be the modality of choice because of the relatively thick slices and the long acquisition times.
Reliability of a decision-tree model in predicting occupational lead poisoning in a group of highly exposed workers
2016
Objective This study aimed to provide the toxicological profile of some lead-exposed workers and obtain a predictive model for lead poisoning. Methods Data regarding external and absorbed exposure were collected from 585 subjects employed in ten metallurgical production departments. Airborne lead concentration, blood lead level (BLL), cumulative blood lead index (CBLI), urine delta-aminolevulinic acid (DALA), age, workplace/section, exposure period, and whether reported lead poisoning as occupational disease were examined using ANOVA, and, post-ANOVA, Pearson correlation matrix, PCA (principal component analysis), decision-tree modeling, and logistic modeling. Results BLL was less sensitive…
In utero exposure to mixtures of xenoestrogens and child neuropsychological development.
2014
BACKGROUND: To date, no epidemiological studies have explored the impact and persistence of in utero exposure to mixtures of xenoestrogens on the developing brain. We aimed to assess whether the cumulative effect of xenoestrogens in the placenta is associated with altered infant neuropsychological functioning at two and at four years of age, and if associations differ among boys and girls. METHODS: Cumulative prenatal exposure to xenoestrogens was quantified in the placenta using the biomarker Total Effective Xenoestrogen Burden (TEXB-alpha) in 489 participants from the INMA (Childhood and the Environment) Project. TEXB-alpha was split in tertiles to test its association with the mental and…
Aerosol Health Effects from Molecular to Global Scales.
2017
Poor air quality is globally the largest environmental health risk. Epidemiological studies have uncovered clear relationships of gaseous pollutants and particulate matter (PM) with adverse health outcomes, including mortality by cardiovascular and respiratory diseases. Studies of health impacts by aerosols are highly multidisciplinary with a broad range of scales in space and time. We assess recent advances and future challenges regarding aerosol effects on health from molecular to global scales through epidemiological studies, field measurements, health-related properties of PM, and multiphase interactions of oxidants and PM upon respiratory deposition. Global modeling combined with epide…
Multigenerational study of the obesogen effects of bisphenol S after a perinatal exposure in C57BL6/J mice fed a high fat diet.
2021
International audience; Background : Bisphenol S is an endocrine disruptor exhibiting metabolic disturbances, especially following perinatal exposures. To date, no data are available on the obesogen effects of BPS in a mutligenerational issue.Objectives : We investigated obesogen effects of BPS in a multigenerational study by focusing on body weight, adipose tissue and plasma parameters in male and female mice.Methods : Pregnant C57BL6/J mice were exposed to BPS (1.5 μg/kg bw/day ie a human equivalent dose of 0.12 μg/kg bw/day) by drinking water from gestational day 0 to post natal day 21. All offsprings were fed with a high fat diet during 15 weeks. Body weight was monitored weekly and fat…
