Female Athlete’s Heart

Background: Most of our knowledge on training-induced cardiac remodeling is derived from men, with the paucity of data from women representing an important gap in knowledge. The aim of the study was to define the electrocardiographic and morphological features of female athlete’s heart, with special attention to differences related to sex and sport. Methods: Seven hundred twenty Olympic athletes (360 females and 360 age- and sport-matched males, mean age: 23±5 years) were evaluated by clinical, resting, and exercise electrocardiography and echocardiography. Results: Anterior T-wave inversion was more common in females than males (P<0.05). Left ventricular (LV) wall thickness and LV mass were greater in men (P<0.001). Females had smaller absolute but greater indexed LV and right ventricular (RV) dimensions as compared to males. Most women had normal LV geometry (80.8%). A progressive increase in LV/RV dimensions was observed in women from those engaged in skill, power, to mixed and endurance disciplines, with the endurance ones demonstrating the greatest degree of RV dilatation. Women had a peculiar biventricular adaptation, with higher LV/RV (1.41±0.16 versus 1.36±0.15, P<0.0001) and lower RV inflow/outflow ratio (P<0.001), as compared to men. Conclusions: Sex significantly affects cardiac remodeling in athletes, with females presenting a different electrical and structural remodeling. Women maintain a normal LV geometry, with relative larger increase of cavity dimensions compared with men. Type of sport has a relevant impact, with endurance athletes exhibiting the greatest degree of RV and LV dimensional remodeling. The present study confirms the need for a sex-based approach for interpreting the complex features of athlete’s heart in women.
The Pretreatment Gut Microbiome Is Associated With Lack of Response to Methotrexate in New‐Onset Rheumatoid Arthritis

Although oral methotrexate (MTX) remains the anchor drug for rheumatoid arthritis (RA), up to 50% of patients do not achieve a clinically adequate outcome. In addition, there is a lack of prognostic tools for treatment response prior to drug initiation. This study was undertaken to investigate whether interindividual differences in the human gut microbiome can aid in the prediction of MTX efficacy in new‐onset RA.
Suppression of long noncoding RNA LINC00324 restricts cell proliferation and invasion of papillary thyroid carcinoma through downregulation of TRIM29 via upregulating microRNA-195-5p

Long noncoding RNAs (lncRNAs) are identified as novel regulators of carcinogenesis. To date, the precise functions of lncRNAs in papillary thyroid carcinoma (PTC) remains poorly understood. The purposes of this work were to explore the potential relevance of lncRNA 00324 (LINC00324) in PTC. Levels of LINC00324 were markedly up-regulated in PTC. Silencing of LINC00324 significantly repressed the proliferation and invasion of PTC cells. LINC00324 was documented as a sponge of microRNA-195-5p (miR-195-5p). Decreased levels of miR-195-5p were detected in PTC. The up-regulation of miR-195-5p suppressed PTC cellular proliferation and invasion. Suppression of miR-195-5p partially reversed the LINC00324-knockdown-mediated effects in PTC cells. We identified tripartite motif-containing 29 (TRIM29) as a target gene of miR-195-5p. TRIM29 overexpression partially reversed the LINC00324-knockdown- or miR-195-5p-overexpression-mediated effects in PTC cells. In short, this work demonstrates that LINC00324 knockdown inhibits the proliferation and invasion of PTC cells by decreasing TRIM29 expression via up-regulating miR-195-5p expression.
Burkholderia ubonensis High-Level Tetracycline Resistance Is Due to Efflux Pump Synergy Involving a Novel TetA(64) Resistance Determinant

Burkholderia ubonensis, a nonpathogenic soil bacterium belonging to the Burkholderia cepacia complex (Bcc), is highly resistant to some clinically significant antibiotics. The concern is that B. ubonensis may serve as a resistance reservoir for Bcc or B. pseudomallei complex (Bpc) organisms that are opportunistic human pathogens. ABSTRACT Burkholderia ubonensis, a nonpathogenic soil bacterium belonging to the Burkholderia cepacia complex (Bcc), is highly resistant to some clinically significant antibiotics. The concern is that B. ubonensis may serve as a resistance reservoir for Bcc or B. pseudomallei complex (Bpc) organisms that are opportunistic human pathogens. Using a B. ubonensis strain highly resistant to tetracycline (MIC, ≥256 µg/ml), we identified and characterized tetA(64) that encodes a novel tetracycline-specific efflux pump of the major facilitator superfamily. TetA(64) and associated TetR(64) regulator expression are induced by tetracyclines. Although TetA(64) is the primary tetracycline and doxycycline resistance determinant, maximum tetracycline and doxycycline resistance requires synergy between TetA(64) and the nonspecific AmrAB-OprA resistance nodulation cell division efflux pump. TetA(64) does not efflux minocycline, tigecycline, and eravacycline. Comprehensive screening of genome sequences showed that TetA(64) is unequally distributed in the Bcc and absent from the Bpc. It is present in some major cystic fibrosis pathogens, like Burkholderia cenocepacia, but absent from others like Burkholderia multivorans. The tetR(64)-tetA(64) genes are located in a region of chromosome 1 that is highly conserved in Burkholderia sp. Because there is no evidence for transposition, the tetR(64)-tetA(64) genes may have been acquired by homologous recombination after horizontal gene transfer. Although Burkholderia species contain a resident multicomponent efflux pump that allows them to respond to tetracyclines up to a certain concentration, the acquisition of the single-component TetA(64) by some species likely provides the synergy that these bacteria need to defend against high tetracycline concentrations in niche environments.
Poststroke acute dysexecutive syndrome, a disorder resulting from minor stroke due to disruption of network dynamics

Significance Patients with small infarcts often demonstrate a poststroke acute dysexecutive syndrome resulting in failure to successfully re-integrate into society. The mechanism is poorly understood given that lesions are small and do not typically involve areas classically associated with cognitive decline. This knowledge gap makes designing treatment strategies difficult. We used MEG to evaluate changes in cerebral processing in individuals with small strokes. MEG showed a decrease in the amplitude of activation and temporal dispersion of activation peaks in areas responsible for visual word processing, along with an inability to modulate activity in response to task difficulty. These changes suggest disruption of network dynamics resulting in inefficient processing. Functional connectivity studies to isolate affected networks are the critical next step. Stroke patients with small central nervous system infarcts often demonstrate an acute dysexecutive syndrome characterized by difficulty with attention, concentration, and processing speed, independent of lesion size or location. We use magnetoencephalography (MEG) to show that disruption of network dynamics may be responsible. Nine patients with recent minor strokes and eight age-similar controls underwent cognitive screening using the Montreal cognitive assessment (MoCA) and MEG to evaluate differences in cerebral activation patterns. During MEG, subjects participated in a visual picture–word matching task. Task complexity was increased as testing progressed. Cluster-based permutation tests determined differences in activation patterns within the visual cortex, fusiform gyrus, and lateral temporal lobe. At visit 1, MoCA scores were significantly lower for patients than controls (median [interquartile range] = 26.0 [4] versus 29.5 [3], P = 0.005), and patient reaction times were increased. The amplitude of activation was significantly lower after infarct and demonstrated a pattern of temporal dispersion independent of stroke location. Differences were prominent in the fusiform gyrus and lateral temporal lobe. The pattern suggests that distributed network dysfunction may be responsible. Additionally, controls were able to modulate their cerebral activity based on task difficulty. In contrast, stroke patients exhibited the same low-amplitude response to all stimuli. Group differences remained, to a lesser degree, 6 mo later; while MoCA scores and reaction times improved for patients. This study suggests that function is a globally distributed property beyond area-specific functionality and illustrates the need for longer-term follow-up studies to determine whether abnormal activation patterns ultimately resolve or another mechanism underlies continued recovery.
Shared Situational Awareness in a Professional Soccer Team: An Explorative Analysis of Post-Performance Interviews

Sport science research has done little to elaborate on the cognitive factors that turn a collection of individual players into a coordinated elite team. The purpose of this paper is to clarify if the players and coach of an elite soccer team express shared situational awareness. Ten players and one coach were exposed to twelve video pictures from a previous soccer match, and their statements for each picture were recorded and analyzed using a qualitative approach. Two of five game situations were with ball possession and three out of seven were without ball possession; the player statements are contradictory, with a high threat for inadequate coordination. In seven of the twelve game situations, the players’ statements coincided and expressed a shared situational awareness, with good opportunities for adequate defensive and offensive coordination. In two of the game situations, there was a high threat for inadequate coordination. There was consensus among 9 out of 10 players, but the player with the divergent statement was central in the situation. The procedure followed in the study could be used to elucidate if a team has shared situational awareness and clarify in which situations there exists discrepancies and data that can be used to improve team coordination on and off the field.
Modelling gas mixture adsorption in active carbons

We review recent progress made concerning the modelling of equilibrium gas mixture adsorption in activated carbons. Much of the discussion focuses on modern statistical mechanical methods, such as classical density functional theory and Monte-Carlo simulation, as well as the surface models employed, i.e. the surface characterisation, and we confine our attention to work that has been compared quantitatively with experiment. We will see that for less demanding scenarios, i.e. relatively simple gas mixtures adsorbed at supercritical temperatures, current methods are satisfactory. But further developments in our models and theories are probably needed to describe the adsorption of more complex adsorbates such as those involving water at room temperature.
Carbon‐13–fluorine‐19 coupling constants in benzotrifluorides

The carbon–fluorine coupling constants in 33 different substituted benzotrifluorides (trifluoromethyl-benzenes) have been determined. The 3J(CF) to the ortho aromatic ring carbons varied between 1.7 and 5.6 Hz and, in a given molecule, were always larger than the 5J(CF) to the para carbon, which ranged between 0.7 and 1.7 Hz. Coupling to the meta carbons, 4J(CF), was not observed and is under 0.3 Hz.
Pattern of thermal damage and tissue carbonisation from endovenous radiofrequency ablation catheter – Using an in vitro porcine liver model

Background Successful endovenous thermoablation relies on transmural vein wall ablation. We investigated the pattern of thermal spread and tissue carbonisation from RadioFrequency-induced ThermoTherapy (RFiTT) at different powers and pull back methods, using a porcine liver model. Methods We used a previously validated in-vitro porcine liver model. Different powers from 5–25 W were used to administer 150 J. We compared continuous and pulsed energy delivery. Length, lateral spread, and total area of thermal damage, together with any tissue carbonisation, was measured using digital analysis software. Results All experiments used 150 J total energy. Total thermal damage area was smaller with lower power and pulsed energy. Continuous energy caused more tissue carbonisation than pulsed except at 25 W. Conclusion Reduced thermal damage with lower power or pulsed energy results from cooling due to increased time of treatment. Increasing the power increases tissue carbonisation. Optimal treatment is determined by the highest power used continuously that does not cause tissue carbonisation.
Reduction of traditional food consumption in Brazilian diet: trends and forecasting of bean consumption (2007–2030)

Abstract Objective: To identify changes in traditional dietary behaviour through the evaluation of trends in bean consumption among adults in Brazil between 2007 and 2017 and to estimate its projections up to 2030. Design: Time-series analysis conducted with data from the Surveillance System for Protective and Risk Factors for Chronic Diseases by Telephone Survey (Vigitel) between 2007 and 2017. Weekly consumption of beans was analysed. Prais–Winsten regression evaluated trends for the entire period of study (2007–2017) and in two periods of analyses (2007–2011 and 2012–2017) for the complete set of the population and stratified by socio-demographic characteristics. Estimated prevalence projections were calculated up to the year 2030 using its tendency from 2012 to 2017. Setting: Brazil. Participants: A probabilistic sample of 572 675 Brazilian adults aged ≥ 18 years. Results: Changes in traditional dietary pattern were identified. Regular consumption of beans (≥ 5 d/week) presented a stable prevalence trend for the total population in the complete and the first analysed period, but a significant decrease in the second half (67·5 % to 59·5 %) among both genders, all age groups and educational levels (except for ≥12 years). The higher magnitude of regular consumption of beans will occur up to the year of 2025 for the total population (46·9 %), when it will be less frequent in the week. Conclusion: Reductions in the weekly consumption of beans may represent the weakness of a traditional food culture in a globalised food system. By 2025, regular consumption of beans will cease to be the predominant habit in the country.
Extended‐amygdala intrinsic functional connectivity networks: A population study

Pre‐clinical and human neuroimaging research implicates the extended‐amygdala (ExtA) (including the bed nucleus of the stria terminalis [BST] and central nucleus of the amygdala [CeA]) in networks mediating negative emotional states associated with stress and substance‐use behaviours. The extent to which individual ExtA structures form a functionally integrated unit is controversial. We utilised a large sample (n > 1,000 healthy young adult humans) to compare the intrinsic functional connectivity networks (ICNs) of the BST and CeA using task‐free functional magnetic resonance imaging (fMRI) data from the Human Connectome Project. We assessed whether inter‐individual differences within these ICNs were related to two principal components representing negative disposition and alcohol use. Building on recent primate evidence, we tested whether within BST‐CeA intrinsic functional connectivity (iFC) was heritable and further examined co‐heritability with our principal components. We demonstrate the BST and CeA to have discrete, but largely overlapping ICNs similar to previous findings. We found no evidence that within BST—CeA iFC was heritable; however, post hoc analyses found significant BST iFC heritability with the broader superficial and centromedial amygdala regions. There were no significant correlations or co‐heritability associations with our principal components either across the ICNs or for specific BST‐Amygdala iFC. Possible differences in phenotype associations across task‐free, task‐based, and clinical fMRI are discussed, along with suggestions for more causal investigative paradigms that make use of the now well‐established ExtA ICNs.
Age and growth of Gray Triggerfish Balistes capriscus from trans-Atlantic populations.

Anthropogenic factors that negatively impact reef fishes can include changes in life history patterns of fisheries-target species. Understanding these impacts on growth and population age structure is essential in the management of exploited populations of fishes. This is the first study to directly compare age and growth for a major fisheries species between east and west populations of a transatlantic reef fish. The main goal of this study was to document age and growth in gray triggerfish Balistes capriscus from coastal waters of Ghana in the Gulf of Guinea and compare those with previous growth studies from that research and with the western Atlantic population. A secondary objective of this study was to evaluate the use of otoliths to age triggerfish and to provide a preliminary comparison with spine-derived age estimates. Results from this study provided an updated understanding of the growth and age structure of the eastern B. capriscus population in Gulf of Guinea. We documented that shifts in population attributes occurred for B. capriscus after its major decline in abundance. The differences in physical and biotic characteristics of the east and west Atlantic regions and differences in collection methods of samples make direct comparisons of growth parameters difficult, however overall differences in maximum sizes and ages were apparent; the western Atlantic population had a larger maximum size and older maximum age. We also documented that sagittal otoliths can be used to provide age estimates for triggerfish species and compared to dorsal spines, otoliths as an ageing structure had better between reader precision compared to dorsal spines.

NPR1 is required for root colonization and the establishment of a mutualistic symbiosis between the beneficial bacterium Rhizobium radiobacter and barley.

Non-expressor of pathogenesis-related genes 1 (NPR1) is a key regulator of plant innate immunity and systemic disease resistance. The model for NPR1 function are based on experimental evidence obtained largely from dicots, however this model does not fit all aspects of Poaceae family, which includes major crops such as wheat, rice and barley. In addition, there is little scientific data on NPR1's role in mutualistic symbioses. We assessed barley (Hordeum vulgare) HvNPR1 requirement during establishment of mutualistic symbiosis between barley and beneficial Alphaproteobacterium Rhizobium radiobacter F4 (RrF4). Upon RrF4 root-inoculation, barley NPR1-knock down (KD-hvnpr1) plants lost the typical spatiotemporal colonization pattern and supported less bacterial multiplication. Following RrF4 colonization, expression of salicylic acid (SA) marker genes were strongly enhanced in wild type roots; whereas in comparison, KD-hvnpr1 roots exhibited little to no induction. Both basal and RrF4-induced root-initiated systemic resistance against virulent Blumeria graminis were impaired in leaves of KD-hvnpr1. Besides these immune-related differences, KD-hvnpr1 plants displayed higher root and shoot biomass than WT. However, RrF4-mediated growth promotion was largely compromised in KD-hvnpr1. Our results demonstrate a critical role for HvNPR1 in establishing a mutualistic symbiosis between a beneficial bacterium and a cereal crop. This article is protected by copyright.

An engineered extraplastidial pathway for carotenoid biofortification of leaves

Summary Carotenoids are lipophilic plastidial isoprenoids highly valued as nutrients and natural pigments. A correct balance of chlorophylls and carotenoids is required for photosynthesis and therefore highly regulated, making carotenoid enrichment of green tissues challenging. Here we show that leaf carotenoid levels can be boosted through engineering their biosynthesis outside the chloroplast. Transient expression experiments in Nicotiana benthamiana leaves indicated that high extraplastidial production of carotenoids requires an enhanced supply of their isoprenoid precursors in the cytosol, which was achieved using a deregulated form of the main rate‐determining enzyme of the mevalonic acid (MVA) pathway. Constructs encoding bacterial enzymes were used to convert these MVA‐derived precursors into carotenoid biosynthetic intermediates that do not normally accumulate in leaves, such as phytoene and lycopene. Cytosolic versions of these enzymes produced extraplastidial carotenoids at levels similar to those of total endogenous (i.e. chloroplast) carotenoids. Strategies to enhance the development of endomembrane structures and lipid bodies as potential extraplastidial carotenoid storage systems were not successful to further increase carotenoid contents. Phytoene was found to be more bioaccessible when accumulated outside plastids, whereas lycopene formed cytosolic crystalloids very similar to those found in the chromoplasts of ripe tomatoes. This extraplastidial production of phytoene and lycopene led to an increased antioxidant capacity of leaves. Finally, we demonstrate that our system can be adapted for the biofortification of leafy vegetables such as lettuce.
Genome-Wide Analysis Revealed Homozygosity and Demographic History of Five Chinese Sheep Breeds Adapted to Different Environments

Homozygosity of long sequence genotypes are a result of parents transmitting identical haplotypes, which can be used to estimate their auto-zygosity. Therefore, we used high-density SNP Chip data to characterize the auto-zygosity of each breed according to the occurrence and distribution of runs of homozygosity (ROH). Subsequently, we identified the genomic regions with high runs of homozygosity frequencies within individuals of each breed. We selected 96 sheep samples from five local Chinese sheep breeds belonging to different geographical locations. We identified 3046 ROHs within the study breed individuals, among which the longer segments (>1–5 Mb) were dominant. On average, ROH segments covered about 12% of the genomes; the coverage rate of OAR20 was the lowest and that of OAR2 was the highest. The distribution analysis of runs of homozygosity showed that the detected ROH mainly distributed between >26 and 28 Mb. The Hetian and Hu sheep showed the lowest ROH distribution. The estimation of homozygosity level reflects the history of modern and ancient inbreeding, which may affect the genomes of Chinese indigenous sheep breeds and indicate that some animals have experienced recent self-pollination events (Yabuyi, Karakul and Wadi). In these sheep breeds, the genomic regions were assumed to be under selection signatures frequently in line with long ROH. These regions included candidate genes associated with disease resistance traits (5S_rRNA), the innate and adaptive immune response (HERC2 and CYFIP1), digestion and metabolism (CENPJ), growth (SPP1), body size and developments (GJB2 and GJA3). This study highlighted new insights into the ROH patterns and provides a basis for future breeding and conservation strategies of Chinese sheep breeds.
