Variations in Cardiovascular Structure, Function, and Geometry in Midlife Associated With a History of Hypertensive Pregnancy

Field: Medicine (Health Sciences)

Hypertensive pregnancy is associated with increased maternal cardiovascular risk in later life. A range of cardiovascular adaptations after pregnancy have been reported to partly explain this risk. We used multimodality imaging to identify whether, by midlife, any pregnancy-associated phenotypes were still identifiable and to what extent they could be explained by blood pressure. Participants were identified by review of hospital maternity records 5 to 10 years after pregnancy and invited to a single visit for detailed cardiovascular imaging phenotyping. One hundred seventy-three women (age, 42±5 years, 70 after normotensive and 103 after hypertensive pregnancy) underwent magnetic resonance imaging of the heart and aorta, echocardiography, and vascular assessment, including capillaroscopy. Women with a history of hypertensive pregnancy had a distinct cardiac geometry with higher left ventricular mass index (49.9±7.1 versus 46.0±6.5 g/m 2 ; P =0.001) and ejection fraction (65.6±5.4% versus 63.7±4.3%; P =0.03) but lower global longitudinal strain (−18.31±4.46% versus −19.94±3.59%; P =0.02). Left atrial volume index was also increased (40.4±9.2 versus 37.3±7.3 mL/m 2 ; P =0.03) and E:A reduced (1.34±0.35 versus 1.52±0.45; P =0.003). Aortic compliance (0.240±0.053 versus 0.258±0.063; P =0.046) and functional capillary density (105.4±23.0 versus 115.2±20.9 capillaries/mm 2 ; P =0.01) were reduced. Only differences in functional capillary density, left ventricular mass, and atrial volume indices remained after adjustment for blood pressure ( P <0.01, P =0.01, and P =0.04, respectively). Differences in cardiac structure and geometry, as well as microvascular rarefaction, are evident in midlife after a hypertensive pregnancy, independent of blood pressure. To what extent these phenotypic patterns contribute to cardiovascular disease progression or provide additional measures to improve risk stratification requires further study.
Covalently cross-linked hyaluronic acid/BSA/gelatine hydrogels as better surface for cell culture

Field: Materials Science (Physical Sciences)

The mechanical and biomechanical properties of the cell's extracellular matrix is a factor in their later development.In this regard, elastic biocompatible materials as a surface for cultivating cells are in recent years, becoming an exciting field of study.Hydrogels are a hydrophilic 3D network of synthetic polymers or biopolymers.They can have tunable mechanical properties, controllable degradability, or they can be designed for long-time release of treatments.Here, hydrogels from Hyaluronic acid (HA), Bovine serum albumin (BSA) and gelatin was prepared, via carbodiimide chemistry.Morphology and mechanical properties of these hydrogels was characterized via Atomic Force Microscopy (AFM).Young's modulus of HA/BSA and HA/BSA/gel were 124.7 ± 15.9 and 20.3 ± 0.5 kPa, respectively.Mouse embryonic fibroblasts were then cultivated on hydrogels and on the glass surface as a reference.Mechanical and morphological properties of fibroblasts were examined by AFM and via phalloidin-TRITC staying.Relationship between the structure of cells and the type of surface was seen.Cells grown on glass were more flattened with an evenly linear actin structure.On hydrogels, fibroblasts were more star-shaped with non-linear actin structures and many filopodia.Furthermore, height of cells was higher was lower compared to cells on both types of hydrogels (0.36 µm vs. 0.56 µm vs. 1.03 µm).Young's modulus of cells on fibroblast was highest, which relates to the whole range of structural changes linked with surface stiffness.In conclusion, this type of hydrogel might be utilized in the future as a better surface material for cell cultivation.
Příspěvek k chemickému složení minerálů skupiny tetraedritu z Val d´Anniviers (Švýcarsko)

Field: Earth and Planetary Sciences (Physical Sciences)

Historical samples of tetrahedrite from Val d´Anniviers in Switzerland traditionally have been considered as bismuth-rich. New quantitative chemical analyses (EPMA-WDS) of three samples (collections of National Museum, Prague) of the tetrahedrite group minerals from this area show the presence of tetrahedrite-(Fe) with various Bi contents. Significant Bi contents were verified only in one of sample (P1N9933), where tetrahedrite is associated with aikinite, in the range of 0.32 - 0.39 apfu (4.20 - 5.08 wt.% Bi). These contents are comparable to the historical analysis of Fellenberg (1854), who reported 0.42 apfu Bi (5.59 wt.%) in tennantite-(Fe) from this area. In the other two samples, the Bi contents are only minor and range from 0.04 to 0.07 apfu. The empirical formulae calculated on the base of 16 cations apfu are: (Cu5.91Ag0.07)Σ5.98[Cu4.00(Fe0.98Zn0.58Cu0.44)Σ2.00]Σ6.00(Sb1.89As1.76Bi0.36)Σ4.01S13.22 (sample P1N9933); (Cu5.64Ag0.31)Σ5.95[Cu4.00(Fe0.95Zn0.84Cu0.21)Σ2.00]Σ6.00(Sb2.68As1.31Bi0.06)Σ4.05S12.83 (sample P1N9934 large grains), (Cu5.77Ag0.09)Σ5.86[Cu4.00(Fe0.92 Zn0.89Cu0.19)Σ2.00]Σ6.00(Sb3.07As1.06)Σ4.13S12.89 (sample P1N9934 rare tiny grains) and (Cu5.66Ag0.29)Σ5.95[Cu4.00(Fe0.96Zn0.84Cu0.20)Σ2.00]Σ6.00(Sb2.71As1.29Bi0.05)Σ4.05S12.70 (sample P1N69320).
Association between genetically determined leptin and blood lipids considering alcohol consumption: a Mendelian randomisation study

Field: Medicine (Health Sciences)

Objectives The objective of this study was to evaluate the association of genetically determined leptin with lipids. Design We conducted a Mendelian randomisation study to assess a potential causal relationship between serum leptin and lipid levels. We also evaluated whether alcohol drinking modified the associations of genetically determined leptin with blood lipids. Setting and participants 3860 participants of the Framingham Heart Study third generation cohort. Results Both genetic risk scores (GRSs), the GRS generated using leptin loci independent of body mass index (BMI) and GRS generated using leptin loci dependent of BMI, were positively associated with log-transformed leptin (log-leptin). The BMI-independent leptin GRS was associated with log-transformed triglycerides (log-TG, β=−0.66, p=0.01), but not low-density lipoprotein cholesterol (LDL-C, p=0.99), high-density lipoprotein cholesterol (HDL-C, p=0.44) or total cholesterol (TC, p=0.49). Instrumental variable estimation showed that per unit increase in genetically determined log-leptin was associated with 0.55 (95% CI: 0.05 to 1.00) units decrease in log-TG. Besides significant association with log-TG (β=−0.59, p=0.009), the BMI-dependent GRS was nominally associated with HDL-C (β=−10.67, p=0.09) and TC (β=−28.05, p=0.08). When stratified by drinking status, the BMI-dependent GRS was associated with reduced levels of LDL-C (p=0.03), log-TG (p=0.004) and TC (p=0.003) among non-current drinkers only. Significant interactions between the BMI-dependent GRS and alcohol drinking were identified for LDL-C (p=0.03), log-TG (p=0.03) and TC (p=0.02). Conclusion These findings together indicated that genetically determined leptin was negatively associated with lipid levels and the association may be modified by alcohol consumption.
South Africa in a Post-Colonial World: Modernising or Eroding Apartheid?

Field: Social Sciences (Social Sciences)

A week after Verwoerd's assassination on 6 September 1966, the National Party parliamentary caucus chose the Minister of Justice, Police and Prisons, Balthazar Johannes Vorster, as his successor. He was unopposed. Vorster owed his election as Prime Minister to the role he had played in crushing African nationalist opposition to the government. Having been interned during the Second World War for pro-Nazi sympathies as a member of the Ossewa Brandwag (OB), he had a controversial past that added to his reputation as a tough, authoritarian leader. In fact, he was by no means as formidable a figure as his predecessor. He was far more collegial in the way he ran his government. A great deal of leeway was left to individual ministers. While operating with the broad ideological framework established by Verwoerd, Vorster was also more flexible in his interpretation of policy. At the same time, the need for adjustments to existing practices became more pressing during Vorster's premiership as the world moved further into a post-colonial era. He was in power for just over twelve years. That left its mark on both the implementation and interpretation of apartheid, which is reflected in the literature on the politics of South Africa that appeared during his premiership.KeywordsAfrican StateBlack WorkerProgressive PartyNational PartySouth African GovernmentThese keywords were added by machine and not by the authors.

Experimental constraints on fourth generation quark masses

Field: Physics and Astronomy (Physical Sciences)

The existing bounds from CDF on the masses of the fourth generation quarks, t' and b', are reexamined. The bound of 256 GeV on the t' mass assumes that the primary decay of the t' is into q+W, which is not the case for a substantial region of parameter space. The bound of 268 GeV on the b' mass assumes that the branching ratio for b' --> b+Z is very large, which is not only not true for much of parameter space, but is {\em never} true for b' masses above 255 GeV. In addition, it is assumed that the heavy quarks decay within the silicon vertex detector, and for small mixing angles this will not be the case. The experimental bounds, including all of these effects, are found as a function of the other heavy quark mass and the mixing angle.
Mass spectrometry of oxidation products of .DELTA.1- and .DELTA.6-tetrahydrocannabinols.

Field: Chemistry (Physical Sciences)

The mass spectra of Δ1-(Ia), Δ6-tetrahydrocannabinol (Δ6-THC) (IIa), 6α-(IIIa), 6β-hydroxy-(IVa), 7-hydroxy-Δ1-THC (Va), 7-hydroxy-(VIa), 7-oxo-Δ5-THC (VIIa), cannabinol (CBN, VIIIa), 6-hydroxy-(IXa), 7-hydroxy-(Xa), 7-oxo-CBN (XIa) and their acetyl derivatives were determined. Structure correlations and principal fragmentation pathways for these compounds were studied with the aid of the high resolution mass spectrometry and of d3-acetyl derivatives. A typical fragmentation pattern was observed in both spectra of Δ1-and Δ6-THC series. The structure of the essential fragment ion for the compound mentioned above was well characterized by reasonable interpretation.
Four new self-lensing binaries from Kepler: Radial velocity characterization and astrophysical implications

Field: Physics and Astronomy (Physical Sciences)

Abstarct In Kawahara et al. (2018) and Masuda et al. (2019), we reported the discovery of four self-lensing binaries consisting of F/G-type stars and (most likely) white dwarfs whose masses range from 0.2 to 0.6 solar masses. Here we present their updated system parameters based on new radial velocity data from the Tillinghast Reflector Echelle Spectrograph at the Fred Lawrence Whipple Observatory, and the Gaia parallaxes and spectroscopic parameters of the primary stars. We also briefly discuss the astrophysical implications of these findings.

Current Trends of Iridium‐Based Catalysts for Oxygen Evolution Reaction in Acidic Water Electrolysis

Field: Chemistry (Physical Sciences)

The proton exchange membrane water electrolysis (PEMWE) powered by renewable electricity offers a facile route for clean hydrogen production. The oxygen evolution reaction (OER) at the anode plays a major role in affecting the overall device efficiency due to its sluggish OER kinetics. Thus, it remains a challenge to develop robust and active catalysts for OER in acid media for efficient PEMWE. Currently, iridium (Ir)‐based materials, such as mono‐ and multimetallic Ir, Ir‐based oxides, pyrochlore iridate oxides, and Ir‐based perovskites, are the most promising OER catalysts in acid media for PEMWEs. Extensive research has been conducted to enhance the specific activity of Ir species to make cost‐effective. The present review aims to provide the recent progress on addressing the long‐term durability issue of Ir‐based catalyst for OER in acidic conditions, aspiring to inspire the researchers to design highly efficient and stable Ir‐based catalysts. Moreover, the detailed OER mechanism along with the dissolution nature of Ir species is discussed and summarized. Finally, the status, challenges, and prospects for the development of Ir‐based OER catalysts are discussed.

Modern server systems are usually composed in the form of cluster systems in order to serve not only as many users but also as many kinds of applications as possible. The progression of the cluster system architecture leads in a middleware approach based on the Java framework. The middleware approach alleviates the efforts for the construction and the management of a server system but still preserves its performance and applications on the server. In this research, we introduce a new clustering scheme for the easy construction and maintenance of a cluster server system with the Java Management Extensions. We first demonstrate the construction and configuration process. Our experiment sets can verify that it is easy to construct, expand and manage a middleware based cluster system as well as the applications which reside on it. In addition, we can achieve reasonable performance on our service oriented clustered system with the help of state-of-the-art middleware. The experimental results of performance demonstration contain the availability of a server, and the effectiveness of load balancing and scheduling mechanisms. Especially, our service oriented scheduling mechanism was shown to successfully manage load imbalance under the normal load and cope with the overloaded situations, compared with other known scheduling mechanisms.

Congenital brain anomalies and chromosomal aberrations from the Zagreb Collection of human brains

Field: Neuroscience (Life Sciences)

Abstract The Zagreb Collection of developing and adult human brains consists of approximately 1,300 brains of fetuses, children and adults that were collected following routine autopsies in the period from 1974 to 2014. The collection comprises brains of different normal developmental stages that may serve for investigation of normal human brain development. Previous studies on this material have led to several important contributions on human cortical development, such as the discovery of the transient fetal subplate zone. The Zagreb Collection, however, also contains approximately 100 brains with different anomalies including chromosomal aberrations such as Down syndrome. We have analyzed all the available material from the Zagreb Collection and identified 44 brains of fetuses and children with Down syndrome, 10 with Patau syndrome, 6 with Edwards syndrome as well as 7 holoprosencephalic, 7 hydrocephalic and 4 microcephalic brains. The largest part of the Collection is available for further research using modern genetic, immunocytochemical and imaging methods, especially magnetic resonance imaging. Furthermore, the histological slides from the Zagreb Collection are currently being digitally scanned and made available as virtual slides to general scientific audience. The Zagreb Collection represents unique and versatile resource for the future study of normal and abnormal human brain development.

Polyamine polymers from pyrrole, formalin, and amines by use of the mannich reaction

Field: Chemistry (Physical Sciences)

Abstract It was found that pyrrole, one of the active hydrogen compounds, easily condensed with formalin and amine in the presence of acid catalyst to yield a new type of polyamine polymer containing pyrrole nuclei in the main chain of the polymer. This polymerization method was also confirmed to be applicable to the other active hydrogen compounds, such as N ‐methylaniline, acetone, malononitrile, and hydroquinone. The structures of the polymers obtained were determined by infrared NMR and elementary analyses. We named this reaction a Mannich polymerization and the polymers obtained the Mannich base polymer.
Analysis of spermatogonial marker expression in non-human primate

Field: Biochemistry, Genetics and Molecular Biology (Life Sciences)

Human and non-human primate spermatogonia (SPG) share important similarities [1]. Recently, a new classification was proposed for the human SPG compartment based on protein markers such as, MAGEA4, GFRA1, KIT, etc. [2]. Even though, the kinetic of monkey SPG has been previously investigated [3], less is known about the expression profile of spermatogonial markers. Here we tested the hypothesis that SPG marker expression and progression in human and non-human primates is conserved. To this end, we analyzed the expression of human markers, in Macaca fascicularis SPG and their proliferation activity during the stages of the seminiferous epithelium cycle [4, 5].
NATIONAL PROGRAM OF CIVIC-MILITARY SCHOOLS AS A PUBLIC POLICY: A CRITICAL ANALYSIS

Field: Social Sciences (Social Sciences)

This article examines the public policy of the National Program of Civic-Military Schools (PECIM), contextualizing its pedagogical and legal implications within the Brazilian educational system. There is an intense process of mediation between the crisis of education and the non-appropriation in the school space of the management of excellence in educational, pedagogical and administrative processes and the strengthening of human and civic values (hierarchy, structured curriculum, efficiency and productivity, obedience, armed peace and codification), as these lead to the impossibility of understanding the epistemological tasks of education, placing on this expectations that do not belong to him, thus causing a discourse that reveals a posture of alienation in the face of society's broader problems. The objective is to analyze the influences of PECIM in education, focusing on the identities and freedoms of students. The methodology includes bibliographic research, analysis of educational legislation, reading of academic articles and examination of official documents related to the implementation of the program. The results indicate that PECIM may represent a setback by adopting an authoritarian, content-based and neo-technicist teaching model, where the centralization of the teacher's role is accompanied by a decrease in their autonomy. At the same time, public policy also reveals a distortion in investments, with educational resources being diverted to pay military personnel, which compromises the quality and democratic nature of public education. This diversion of resources contradicts the constitutional principles that defend a public, democratic and quality education, accessible to all.

Introduction — From ‘Tragic Mulatto’ to Black Magic Woman: Race, Sex and Religion in Film

Field: Arts and Humanities (Social Sciences)

This research is on representations of black women, sexuality and religion, specifically that of the 'tragic mulatto' character and African-based religions in black films of the 1990s. The objective of this work is to consider how race, sex and religion intersect in constructing a cultural identity for African Diasporas in the United States. Although this cinematic identity is intended for African Diasporas in the US, its implication is that of a wider New World identity.
