Health outcomes of children born after IVF/ICSI: a review of current expert opinion and literature
2014
The Sixth Evian Annual Reproduction (EVAR) Workshop Group Meeting was held to evaluate the impact of IVF/intracytoplasmic sperm injection on the health of assisted-conception children. Epidemiologists, reproductive endocrinologists, embryologists and geneticists presented data from published literature and ongoing research on the incidence of genetic and epigenetic abnormalities and congenital malformations in assisted-conception versus naturally conceived children to reach a consensus on the reasons for potential differences in outcomes between these two groups. IVF-conceived children have lower birthweights and higher peripheral fat, blood pressure and fasting glucose concentrations than …
Regional Susceptibility in VCD Spectra to Dynamic Molecular Motions
2018
Experimental and theoretical studies of the vibrational circular dichroism (VCD) spectrum of 3-methyl-1-(methyldiphenlsilyl)-1-phenylbutan-1-ol, whose absolute configuration is key to elucidating the Brook rearrangement of tertiary benzylic α-hydroxylsilanes, are presented. It is found that the entire OH-bending region in this spectrum—a region that provides important marker bands—cannot be reproduced at all by standard theoretical approaches even though other regions are well described. Using a novel approach to disentangle contributions to the rotational strength of these bands, internal coordinates are identified that critically influence the appearance of this part of the spectrum. We s…
Kristall‐ und Molekülstruktur sowie absolute Konfiguration des (+)‐Benzylmethyl‐α‐naphthylphenylphosphonium‐bromids
1975
(+)-Benzylmethyl-α-naphthylphenylphosphonium-bromid kristallisiert in der Raumgruppe P212121 mit den Gitterkonstanten a = 22.12 A, b = 9.89 A,c = 9.49A und mit vier Molekulen in der Elementarzelle. Die Struktur wurde nach der Schweratommethode aufgeklart und bis zu einem R-Wert von 5.8% verfeinert. Unter Berucksichtigung der anomalen Dispersion konnte die absolute Konfiguration ermittelt werden, es liegt R-Konfiguration vor. Crystal- and Molecular Structure of (+)-Benzylmethyl-α-naphthylphenylphosphonium Bromide (+)-Benzylmethyl-α-naphthylphenylphosphonium bromide crystallizes in the space group P212121 with four molecules in the unit cell of dimensions a = 22.12 A, b = 9.89 A, c = 9.49 A. …
A new result on impulsive differential equations involving non-absolutely convergent integrals
2009
AbstractIn this paper we obtain, as an application of a Darbo-type theorem, global solutions for differential equations with impulse effects, under the assumption that the function on the right-hand side is integrable in the Henstock sense. We thus generalize several previously given results in literature, for ordinary or impulsive equations.
A New Fitness Test of Estimating VO2max in Well-Trained Rowing Athletes
2021
BackgroundThis study was designed to investigate the validity of maximal oxygen consumption (VO2max) estimation through the Firstbeat fitness test (FFT) method when using submaximal rowing and running programs for well-trained athletes.MethodsWell-trained flatwater rowers (n = 45, 19.8 ± 3.0 years, 184 ± 8.7 cm, 76 ± 12.9 kg, and 58.7 ± 6.0 mL⋅kg–1⋅min–1) and paddlers (n = 45, 19.0 ± 2.5 years, 180 ± 7.7 cm, 74 ± 9.4 kg, and 59.9 ± 4.8 mL⋅kg–1⋅min–1) completed the FFT and maximal graded exercise test (GXT) programs of rowing and running, respectively. The estimated VO2max was calculated using the FFT system, and the measured VO2max was obtained from the GXT programs. Differences between the…
Secoiridoids and Iridoids from Morinda asteroscepa
2020
The new 2,3-secoiridoids morisecoiridoic acids A (1) and B (2), the new iridoid 8-acetoxyepishanzilactone (3), and four additional known iridoids (4–7) were isolated from the leaf and stem bark methanol extracts of Morinda asteroscepa using chromatographic methods. The structure of shanzilactone (4) was revised. The purified metabolites were identified using NMR spectroscopic and mass spectrometric techniques, with the absolute configuration of 1 having been established by single-crystal X-ray diffraction analysis. The crude leaf extract (10 μg/mL) and compounds 1–3 and 5 (10 μM) showed mild antiplasmodial activities against the chloroquine-sensitive malaria parasite Plasmodium falciparum (…
Determination of U-Pb ages of zircons by direct measurement of the 210Pb/206Pb ratio
1993
Abstract Precise measurements of the 210Pb/206Pb ratio in zircons permits, for the first time, the determination of complete U-Pb ages by measurement of Pb isotopes only, without determination of the U-Pb ratio by isotope dilution. The 238U daughter isotope 210Pb is generally in radioactive equilibrium with 238U; however, the very short half-life of 210Pb (22.3a) results in extremely low 210Pb/206Pb ratios of ∼ 10−8, especially for Archaean zircons. These ratios have been determined using a Finnigan MAT 262® mass spectrometer equipped with a high abundance sensitivity lens system (RPQ). The accuracy of the 210Pb method has been tested on nine different zircon samples with 207Pb/206Pb ages f…
El caso de los tiradores del Muro de Berlín. A vueltas con algunos debates clásicos de la Filosofía del Derecho del siglo XX
2011
RESUMEN Es artículo analiza el caso de los centinelas del muro de Berlín que disparaban y mataron a algunas personas –que querían pasar la frontera-, amparados por una interpretación del Derecho de la RDA. Algunos años después de la unificación alemana, el Tribunal Constitucional condenó aquellos soldados por asesinato con el argumento que se trataba de Derecho “extremadamente injusto”. Esta es una forma particular de aplicación de la fórmula de Radburch. El objetivo de este artículo es estudiar el caso de los centinelas del Muro de Berlín bajo la perspectiva del la Filosofía del Derecho, particularmente en la controversia entre positivismo y iusnaturalismo. En este sentido, se comparan l…
Who Persistently Creates Jobs? Absolute versus Relative High-Growth Firms
2017
This paper examines the economic contribution of high-growth firms after their high-growth event. While the central role of high-growth firms for job creation is well-established, little is known about their dynamic development in coming periods. We address this question for the first time by comparing absolute with relative growth measures and use data on private firms in Bulgaria for three consecutive 3-year periods (2001-2004, 2004-2007, and 2007-2010). Next to calculating transition probability matrices to investigate growth in employees in coming periods, we model future employment growth by means of a two-part model with separate equations for the probability of survival and exit as w…
The Myth of French Influence Over Spanish Codification: The General Part of the Criminal Codes of 1822 and 1848
2018
The chapter aims to explore the scope of the foreign influences, that of the French in particular, in the criminal codes of 1822 and 1848/50. In doing so, the author departs from the views of some 19th century criminal lawyers who, like J. F. Pacheco, stated that in the old criminal laws “nothing was worthy of respect, or conservation” and “there was only one legitimate and viable system, the system of codification, the system of absolute change,” and recognizing that drafters were fully acquainted with the case of France, a jurisdiction that managed to turn its old laws—including the criminal ones—into modern codes (1804–1811). The author briefly presents the status quaestionis of the dich…
