Observing dynamical phases of BCS superconductors in a cavity QED simulator.

In conventional Bardeen-Cooper-Schrieffer superconductors1, electrons with opposite momenta bind into Cooper pairs due to an attractive interaction mediated by phonons in the material. Although superconductivity naturally emerges at thermal equilibrium, it can also emerge out of equilibrium when the system parameters are abruptly changed2-8. The resulting out-of-equilibrium phases are predicted to occur in real materials and ultracold fermionic atoms, but not all have yet been directly observed. Here we realize an alternative way to generate the proposed dynamical phases using cavity quantum electrodynamics (QED). Our system encodes the presence or absence of a Cooper pair in a long-lived electronic transition in 88Sr atoms coupled to an optical cavity and represents interactions between electrons as photon-mediated interactions through the cavity9,10. To fully explore the phase diagram, we manipulate the ratio between the single-particle dispersion and the interactions after a quench and perform real-time tracking of the subsequent dynamics of the superconducting order parameter using nondestructive measurements. We observe regimes in which the order parameter decays to zero (phase I)3,4, assumes a non-equilibrium steady-state value (phase II)2,3 or exhibits persistent oscillations (phase III)2,3. This opens up exciting prospects for quantum simulation, including the potential to engineer unconventional superconductors and to probe beyond mean-field effects like the spectral form factor11,12, and for increasing the coherence time for quantum sensing.

Unearthing the soil-borne microbiome of land plants.

Plant-soil biodiversity interactions are fundamental for the functioning of terrestrial ecosystems. Yet, the existence of a set of globally distributed topsoil microbial and small invertebrate organisms consistently associated with land plants (i.e., their consistent soil-borne microbiome), together with the environmental preferences and functional capabilities of these organisms, remains unknown. We conducted a standardized field survey under 150 species of land plants, including 58 species of bryophytes and 92 of vascular plants, across 124 locations from all continents. We found that, despite the immense biodiversity of soil organisms, the land plants evaluated only shared a small fraction (less than 1%) of all microbial and invertebrate taxa that were present across contrasting climatic and soil conditions and vegetation types. These consistent taxa were dominated by generalist decomposers and phagotrophs and their presence was positively correlated with the abundance of functional genes linked to mineralization. Finally, we showed that crossing environmental thresholds in aridity (aridity index of 0.65, i.e., the transition from mesic to dry ecosystems), soil pH (5.5; i.e., the transition from acidic to strongly acidic soils), and carbon (less than 2%, the lower limit of fertile soils) can result in drastic disruptions in the associations between land plants and soil organisms, with potential implications for the delivery of soil ecosystem processes under ongoing global environmental change.

Squeezing Multilevel Atoms in Dark States via Cavity Superradiance.

We describe a method to create and store scalable and long-lived entangled spin-squeezed states within a manifold of many-body cavity dark states using collective emission of light from multilevel atoms inside an optical cavity. We show that the system can be tuned to generate squeezing in a dark state where it will be immune to superradiance. We also show more generically that squeezing can be generated using a combination of superradiance and coherent driving in a bright state, and subsequently be transferred via single-particle rotations to a dark state where squeezing can be stored. Our findings, readily testable in current optical cavity experiments with alkaline-earth-like atoms, can open a path for dissipative generation and storage of metrologically useful states in optical transitions.

Synthesis of a [18F]F Estradiol Derivative via Click Chemistry Using an Automated Synthesis Module: In Vitro Evaluation as Potential Radiopharmaceutical for Breast Cancer Imaging.

"Click reactions" are a very useful tool for the selective conjugation of different molecular subunits to produce complex structures in a simple way. In this paper, we present the application of Cu(I)-catalyzed biorthogonal reactions between alkynes and azides to the indirect radiofluorination of an estradiol derivative with potential applications in estrogen receptor imaging. The procedure was fully developed on an automated synthesis platform, and conditions were optimized to achieve the desired product with a reasonable yield without precipitation. Although the biological results were not adequate for a potential radiopharmaceutical, the outcome of this work is valuable since the use of automated platforms is required for the reliable and reproducible preparation of PET radiopharmaceuticals in GMP conditions while limiting the radiation dose rates to the personnel.

Faecal Short-Chain, Long-Chain, and Branched-Chain Fatty Acids as Markers of Different Chronic Inflammatory Enteropathies in Dogs.

Chronic inflammatory enteropathies (CIEs) are classified based on treatment trials, and new methods are being sought for earlier differentiation and characterization. Giardia infection (GIA) is one of the first differential diagnoses and may be present in CIE-affected dogs. The aim of this study was to evaluate the faecal characteristics and faecal fatty acid profile (short, medium, long, and branched-chain fatty acids) in dogs with food-responsive enteropathy (FRE), immunosuppressant-responsive enteropathy (IRE), and dogs infected with Giardia compared to healthy control (HC) animals as a potential non-invasive indicator of intestinal health that helps in the differentiation of CIEs. The C16:1n-7 percentage (p = 0.0001) and C16:1n-7/C16:0 ratio (p = 0.0001) served to differentiate between HC, FRE, and IRE. IRE dogs presented lower levels of short-chain fatty acids (∑SCFAs) (p = 0.0008) and acetic acid (C2) (p = 0.0007) compared to the other three groups and lower propionic acid (C3) (p = 0.0022) compared to HCs. IRE and GIA presented higher faecal fat content (p = 0.0080) and ratio of iso/anteiso branched-chain fatty acids (BCFAs) compared to HC and FRE. Correlations between some fatty acids and desaturation indices with the canine inflammatory bowel disease activity index and faecal characteristics were observed, suggesting that these compounds could play an important role in the pathogenesis of these diseases.

Momentum-exchange interactions in a Bragg atom interferometer suppress Doppler dephasing.

Large ensembles of laser-cooled atoms interacting through infinite-range photon-mediated interactions are powerful platforms for quantum simulation and sensing. Here we realize momentum-exchange interactions in which pairs of atoms exchange their momentum states by collective emission and absorption of photons from a common cavity mode, a process equivalent to a spin-exchange or XX collective Heisenberg interaction. The momentum-exchange interaction leads to an observed all-to-all Ising-like interaction in a matter-wave interferometer. A many-body energy gap also emerges, effectively binding interferometer matter-wave packets together to suppress Doppler dephasing in analogy to Mössbauer spectroscopy. The tunable momentum-exchange interaction expands the capabilities of quantum interaction-enhanced matter-wave interferometry and may enable the realization of exotic behaviors, including simulations of superconductors and dynamical gauge fields.

Long-Term Effect of Maternal Antioxidant Supplementation on the Lipid Profile of the Progeny According to the Sow's Parity Number.

Pig feeding prior to the extensive fattening phase might affect the final lipid profile and product quality. This study evaluates how maternal supplementation with vitamin E (VITE) (100 mg/kg), hydroxytyrosol (HXT) (1.5 mg/kg), or combined administration (VE + HXT) affects the piglet's plasma and tissues' fatty acid profiles and lipid stability according to the sow's parity number (PN), as well as the possible changes to the lipid profile after extensive feeding. The sows' PN affected the total fatty acid profile of plasma, muscle, and liver of piglets, with lower Δ-9 and Δ-6 desaturase indices but higher Δ-5 in those from primiparous (P) than multiparous (M) sows. Dietary VITE was more effective at decreasing C16:0 and saturated fatty acids in the muscle of piglets born from M than P sows, and modified the liver phospholipids in a different way. Sows' supplementation with HXT increased C18:2n-6 in triglycerides and polyunsaturated fatty acids (PUFA) in muscle phospholipids. In the liver, HXT supplementation also increased free-PUFA and free-n-3 fatty acids. However, lipid oxidation of piglets' tissues was not affected by the antioxidant supplementation, and it was higher in the livers of piglets born from M sows. The fatty acid profile in the muscle of pigs after extensive feeding was not affected by the PN, but it was by the sows' antioxidant supplementation, with positive effects on quality by both compounds.

Prenylated Flavanone Isolated from Dalea Species as a Potential Multitarget-Neuroprotector in an In Vitro Alzheimer's Disease Mice Model.

Alzheimer's disease (AD) involves a neurodegenerative process that has not yet been prevented, reversed, or stopped. Continuing with the search for natural pharmacological treatments, flavonoids are a family of compounds with proven neuroprotective effects and multi-targeting behavior. The American genus Dalea L. (Fabaceae) is an important source of bioactive flavonoids. In this opportunity, we tested the neuroprotective potential of three prenylated flavanones isolated from Dalea species in a new in vitro pre-clinical AD model previously developed by us. Our approach consisted in exposing neural cells to conditioned media (3xTg-AD ACM) from neurotoxic astrocytes derived from hippocampi and cortices of old 3xTg-AD mice, mimicking a local neurodegenerative microenvironment. Flavanone 1 and 3 showed a neuroprotective effect against 3xTg-AD ACM, being 1 more active than 3. The structural requirements to afford neuroprotective activity in this model are a 5'-dimethylallyl and 4'-hydroxy at the B ring. In order to search the mechanistic performance of the most active flavanone, we focus on the flavonoid-mediated regulation of GSK-3ß-mediated tau phosphorylation previously reported. Flavanone 1 treatment decreased the rise of hyperphosphorylated tau protein neuronal levels induced after 3xTg-AD ACM exposure and inhibited the activity of GSK-3ß. Finally, direct exposure of these neurotoxic 3xTg-AD astrocytes to flavanone 1 resulted in toxicity to these cells and reduced the neurotoxicity of 3xTg-AD ACM as well. Our results allow us to present compound 1 as a natural prenylated flavanone that could be used as a precursor to development and design of future drug therapies for AD.

Therapeutic role of voltage-gated potassium channels in age-related neurodegenerative diseases.

Voltage-gated ion channels are essential for membrane potential maintenance, homeostasis, electrical signal production and controlling the Ca2+ flow through the membrane. Among all ion channels, the key regulators of neuronal excitability are the voltage-gated potassium channels (KV), the largest family of K+ channels. Due to the ROS high levels in the aging brain, K+ channels might be affected by oxidative agents and be key in aging and neurodegeneration processes. This review provides new insight about channelopathies in the most studied neurodegenerative disorders, such as Alzheimer Disease, Parkinson's Disease, Huntington Disease or Spinocerebellar Ataxia. The main affected KV channels in these neurodegenerative diseases are the KV1, KV2.1, KV3, KV4 and KV7. Moreover, in order to prevent or repair the development of these neurodegenerative diseases, previous KV channel modulators have been proposed as therapeutic targets.

Developing technologies to assess vascular ageing: a roadmap from VascAgeNet.

Vascular ageing is the deterioration of arterial structure and function which occurs naturally with age, and which can be accelerated with disease. Measurements of vascular ageing are emerging as markers of cardiovascular risk, with potential applications in disease diagnosis and prognosis, and for guiding treatments. However, vascular ageing is not yet routinely assessed in clinical practice. A key step towards this is the development of technologies to assess vascular ageing. In this Roadmap, experts discuss several aspects of this process, including: measurement technologies; the development pipeline; clinical applications; and future research directions. The Roadmap summarises the state of the art, outlines the major challenges to overcome, and identifies potential future research directions to address these challenges.

RESUMEN Fundamento: el parto pretérmino es un problema de salud pública por las repercusiones sobre la vida del niño al causar el 75 % de la morbilidad y mortalidad neonatales. Objetivo: identificar factores de riesgo asociados al parto pretérmino. Métodos: estudio descriptivo, correlacional, de corte transversal de dos series de casos que incluyó 678 gestantes de la provincia de Cienfuegos durante el año 2012; de ellas un grupo de 226 con parto entre 28 y 36,6 s semanas y otro grupo de 452 con parto después de las 37 semanas. Se analizó la edad gestacional al ingreso, factores de riesgo de prematuridad, presencia de modificaciones cervicales al examen clínico y por ultrasonido transvaginal. Se calculó Chi cuadrado con una confiabilidad del 95 % y el cociente de posibilidades. Resultados: las edades extremas y el nivel de escolaridad entre séptimo y noveno grados influyeron de manera significativa a favor de las gestantes con parto pretérmino. Otros factores como el hábito de fumar, la ingestión de bebidas alcohólicas, embarazo pretérmino anterior (OR=2,32), pre-eclampsia (OR=6,31), crecimiento intrauterino retardado (OR=3,77), infecciones urinarias (OR=3, 41), y vaginales, la rotura prematura de membranas y las modificaciones cervicales (OR>2), mostraron diferencias altamente significativas en las gestantes con parto pretérmino. Conclusiones: la pre-eclampsia, el crecimiento intrauterino retardado y las infecciones urinarias fueron los factores de riesgo con mayor cociente de posibilidad para parto pretérmino, no obstante existen otros que también lo potencian. La modificación de estos factores constituye pilar para la disminución del parto pretérmino.

ABSTRACT Foundation: preterm delivery is a public health problem due to the repercussions on the child´s life, causing 75% of neonatal morbidity and mortality. Objective: to identify risk factors associated with preterm delivery. Methods: descriptive, correlational, cross-sectional study of two case series that included 678 pregnant women from the Cienfuegos province during 2012; out of them a group of 226 who had deliveries between 28 and 36.6 s weeks and another group of 452 with delivery after 37 weeks. Gestational age at admission, risk factors for prematurity, presence of cervical changes to clinical examination and trans-vaginal ultrasound were analyzed. Chi- square was calculated with 95% reliability and the quotient of possibilities. Results: extreme ages and schooling level of between seventh and ninth grades influenced significantly in favor of pregnant women with preterm delivery. Other factors such as smoking, alcohol ingestion, previous preterm pregnancy (OR = 2.32), pre-eclampsia (OR = 6.31), delayed intrauterine growth (OR = 3.77), urinary infections ( OR = 3, 41), and vaginal, premature rupture of membranes and cervical changes (OR> 2), showed highly significant differences in pregnant women with preterm delivery. Conclusions: pre-eclampsia, delayed intrauterine growth and urinary tract infections were the risk factors with the highest possibility ratio for preterm delivery, however there are others that also enhance it. Modifying these factors is determinant for decreasing preterm deliveries.

Marcación de un derivado de glucosa con 99mTc mediante la formación de un complejo Tc(V)-nitruro: estudios preliminares / Labelling of a glucose derivative with 99mTc through the formation of a Tc(V)-nitride symmetrical complex: preliminary studies

La preparación de derivados de glucosa marcados con 99mTc reviste gran interés para la evaluación del consumo de glucosa in vivo en oncología y cardiología nuclear. Este trabajo presenta la marcación de un análogo de glucosa (GLU-DTC) mediante la formación de un complejo Tc(V)-nitruro simétrico. Para ello se incorporó a la biomolécula un grupo ditiocarbamato capaz de coordinar al metal. La marcación fue realizada mediante sustitución de ligandos, obteniéndose una única especie con pureza radioquímica superior al 90 por cientp, la que se mantuvo durante al menos 4 hs. La caracterización fisicoquímica y biológica muestra que el complejo 99mTc(V)-nitruro(GLU-DTC)2 es un compuesto estable y altamente hidrofílico, aunque su unión a proteínas plasmáticas es mayor a la esperada, hecho que justificaría la alta actividad retenida en sangre y en hígado durante la evaluación biológica en ratones CD1 normales. Estos resultados indican que la marcación con 99mTc de este derivado de glucosa produce una alteración significativa de su comportamiento biológico.

The preparation of 99mTc-labeled glucose derivatives is of great interest to evaluate the in vivo glucose uptake in nuclear oncology and cardiology. This paper presents the labelling of a glucose analogue (GLU-DTC) through the formation of a Tc(V)-nitride symmetrical complex. For this purpose, a dithiocarbamate group was incorporated to the biomolecule, in order to coordinate the metal. The labelling reaction was carried out by substitution yielding a single complex with radiochemical purity above 90 percent. This complex was stable for at least 4 hours. The physicochemical and biological characterization shows that the 99mTc(V)-nitride(GLU-DTC)2 complex is a stable and highly hydrophilic compound, although its plasma protein binding is greater than expected, a fact which justifies the high activity retained in blood and liver during the biological evaluation in normal CD1 mice. These results indicate that 99mTc labelling of this glucose derivate alters significantly its biological behaviour.

A adesão a medidas preventivas em saúde bucal em crianças e adolescentes portadores de fissura labiopalatina / Adherence to preventive oral health measures in children and adolescents with cleft lip and palate

O objetivo deste estudo foi o de avaliar a adesão a medidas preventivas em saúde bucal de crianças e adolescentes portadores de fissuras labiopalatinas. A amostra foi composta por crianças e adolescentes com idade entre 5 e 18 anos, portadores de fissura labiopalatina isolada, em tratamento em um hospital de referência para reabilitação de malformações craniofaciais no Rio de Janeiro, entre os meses de agosto e novembro de 2009. O responsável/paciente respondeu a um questionário composto por dados sócio-demográficos e hábitos de higiene bucal e dieta. Através do exame clínico e dos prontuários médico/odontológico, foi possível identificar o tipo de fissura oral: fissura de lábio isolada (FL); fissura de lábio associada ao palato (FLP) e fissura de palato isolada (FP). Cento e oito questionários foram respondidos, e a amostra final foi composta por 100 questionários correspondentes a 53 crianças e 47 adolescentes com a maior prevalência do gênero masculino (55,0%) e indivíduos caucasianos (46%). O tipo de fissura oral mais frequente foi a FLP (63%,0), seguida da fl(19,0%) e da FP (18,0%). A maioria dos participantes do estudo relatou que realizava a escovação dos dentes três vezes ao dia, não fazia uso do fio dental e do enxaguatório bucal. A ingestão de doces entre as refeições foi mais relatada pelas crianças (66,0%), sem diferença estatística entre crianças e adolescentes (p=0,08). Observou-se que 15 (27,3%) meninos e 19 (42,2%) meninas relataram usar fio dental, sem diferença entre os gêneros (p=0,11). De acordo com os resultados observados, a adesão de medidas preventivas em saúde bucal na população foi considerada parcial. Embora a maioria dos participantes realizasse a escovação dentária três vezes ao dia, o uso do fio dental foi negligenciado, e a ingestão de doces entre as refeições foi relatada por um grande número de participantes do estudo.

The aim of this study was to assess the adherence to preventive oral health measures of children and adolescents with cleft lip and palate. The sample was composed of children and adolescents aged varied 5 to 18 years, with isolated cleft lip and palate in treatment at a referral hospital for rehabilitation of craniofacial malformations in Rio de Janeiro, between August and November 2009. The guardian/patient answered a questionnaire comprising socio-demographic data and oral hygiene habits and diet. Through clinical records and medical/dental care, it was possible to identify the type of oral clefts: cleft lip (CL), cleft lip with cleft palate (CLP) and cleft palate alone (CP). One hundred and eight questionnaires were completed and the final sample consisted of 100 questionnaires corresponding to 53 children and 47 adolescents with a higher prevalence of males (55%) and caucasians (46%). The most common type of oral cleft was CLP (63.0%), followed by CL (19.0%) and CP (18.0%). Almost all participants reported that they brushed their teeth three times a day; on the other hand, they did not use dental floss and mouthwash. The intake of sweets between meals was reported more frequently by children (66.0%), no statistical diff erence between children and adolescents (p=0.08) was observed. It was observed that 15 (27.3%) boys and 19 (42.2%) girls reported using dental floss, there was no diff erence between genders (p=0.11). According to the results, adherence to preventive measures in oral health in this population was considered partial. Although most participants to perform the tooth brushing three time a day, flossing has been neglected and eating sweets between meals was reported by a large number of study participants.
