The room-temperature X-ray powder diffraction data for bosentan monohydrate, an API used in the treatment of pulmonary arterial hypertension, is presented. Bosentan monohydrate is monoclinic, P21/c (No. 14), with unit cell parameters a = 12.4520(7) Å, b = 15.110(1) Å, c = 15.0849(9) Å, β = 95.119(5)°, V = 2827.0(3) Å3, Z = 4. All the diffraction maxima recorded were indexed and are consistent with the P21/c space group. The crystal structure of this material corresponds to the phase associated with Cambridge Structural Database entry NEQHEY, which was determined at 123 K. The successful Rietveld refinement, carried out with TOPAS-Academic, showed the single-phase nature of the material and the good quality of the data. A comprehensive analysis of intra- and intermolecular interactions corroborates that the structure is dominated by extensive hydrogen bonding, accompanied by C▬H⋯π and π⋯π interactions. Hirshfeld surface analysis and fingerprint plots indicate that the most important interactions are H⋯H and O⋯H/H⋯O in bosentan and the water molecule and C⋯H/H⋯C interactions in bosentan.
The modern marine megafauna is known to play important ecological roles and includes many charismatic species that have drawn the attention of both the scientific community and the public. However, the extinct marine megafauna has never been assessed as a whole, nor has it been defined in deep time. Here, we review the literature to define and list the species that constitute the extinct marine megafauna, and to explore biological and ecological patterns throughout the Phanerozoic. We propose a size cut-off of 1 m of length to define the extinct marine megafauna. Based on this definition, we list 706 taxa belonging to eight main groups. We found that the extinct marine megafauna was conspicuous over the Phanerozoic and ubiquitous across all geological eras and periods, with the Mesozoic, especially the Cretaceous, having the greatest number of taxa. Marine reptiles include the largest size recorded (21 m; Shonisaurus sikanniensis) and contain the highest number of extinct marine megafaunal taxa. This contrasts with today’s assemblage, where marine animals achieve sizes of >30 m. The extinct marine megafaunal taxa were found to be well-represented in the Paleobiology Database, but not better sampled than their smaller counterparts. Among the extinct marine megafauna, there appears to be an overall increase in body size through time. Most extinct megafaunal taxa were inferred to be macropredators preferentially living in coastal environments. Across the Phanerozoic, megafaunal species had similar extinction risks as smaller species, in stark contrast to modern oceans where the large species are most affected by human perturbations. Our work represents a first step towards a better understanding of the marine megafauna that lived in the geological past. However, more work is required to expand our list of taxa and their traits so that we can obtain a more complete picture of their ecology and evolution.
The COVID-19 pandemic has posed an enormous challenge to the mental health of the population with probable differentiated profiles for men and women, although not all studies are consistent. While women are likely to have endured greater loads of stress associated with an increased incidence of mental disorders such as depression, men have been able to abuse alcohol and other drugs more, in addition to complying with prevention recommendations to a lesser extent. As soon as the COVID pandemic began, we began a clinical trial to enhance first-line treatments with three complementary interventions with patients with Major Depression (MD), which has allowed us to analyze differences in response according to gender.
Objectives
As a secondary analysis of a clinical trial, the aim of the current study was to address the relative different efficacy between genders of three psychotherapeutic approaches in the context of MD.
Methods
This study was a secondary analysis of a pragmatic parallel randomized controlled clinical trial that was composed of three arms (Minimal Lifestyle Intervention, Mindfulness-Based Cognitive Therapy, and Lifestyle Modification Program). We recruited 94 individuals (24 men and 70 women) from the Primary Healthcare Centers of the Balearic Islands region in Spain who were currently experiencing an episode of MD. Descriptive and univariate analyses were used to examine between-group differences in sociodemographic and clinical data between the two genders. General Linear Modelling (specifically, repeated measures ANOVA) was performed to compare the effect of gender on the evolution of depressive symptoms (measured by BDI-II).
Results
Significant between-group differences were observed for the evolution of depressive symptoms after controlling for the intervention group and age. These results suggested that being a woman was significantly related to a worse evolution of depressive symptoms. This association implies a large effect size.
Conclusions
The COVID 19 pandemic has not only been able to predispose women to Depression to a greater extent, but it is also possible that it has negatively conditioned their response to antidepressant therapies compared to men. However, our data suggest the possibility that greater psychological support could help prevent this situation.
The SARS-CoV-2 Omicron variant has increased infectivity and immune escape compared with previous variants, and caused the surge of massive COVID-19 waves globally. Despite a vast majority (~90%) of the population of Santa Fe city, Argentina had been vaccinated and/or had been infected by SARS-CoV-2 when Omicron emerged, the epidemic wave that followed its arrival was by far the largest one experienced in the city. A serosurvey conducted prior to the arrival of Omicron allowed to assess the acquired humoral defences preceding the wave and to conduct a longitudinal study to provide individual-level real-world data linking antibody levels and protection against COVID-19 during the wave. A very large proportion of 1455 sampled individuals had immunological memory against COVID-19 at the arrival of Omicron (almost 90%), and about half (48.9%) had high anti-spike immunoglobulin G levels (>200 UI/ml). However, the antibody titres varied greatly among the participants, and such variability depended mainly on the vaccine platform received, on having had COVID-19 previously and on the number of days elapsed since last antigen exposure (vaccine shot or natural infection). A follow-up of 514 participants provided real-world evidence of antibody-mediated protection against COVID-19 during a period of high risk of exposure to an immune-escaping highly transmissible variant. Pre-wave antibody titres were strongly negatively associated with COVID-19 incidence and severity of symptoms during the wave. Also, receiving a vaccine shot during the follow-up period reduced the COVID-19 risk drastically (15-fold). These results highlight the importance of maintaining high defences through vaccination at times of high risk of exposure to immune-escaping variants.
Early COVID-19 research suggests a detrimental impact of the initial lockdown on young people's mental health.
Aims
We investigated mental health among university students and young adults after the first UK lockdown and changes in symptoms over 6 months.
Method
In total, 895 university students and 547 young adults not in higher education completed an online survey at T1 (July–September 2020). A subset of 201 university students also completed a 6 month follow-up survey at T2 (January–March 2021). Anxiety, depression, insomnia, substance misuse and suicide risk were assessed.
Results
At T1, approximately 40%, 25% and 33% of the participants reported moderate to severe anxiety and depression and substance misuse risk, clinically significant insomnia and suicidal risk. In participants reassessed at T2, reductions were observed in anxiety and depression but not in insomnia, substance misuse or suicidality. Student and non-student participants reported similar levels of mental health symptoms. Student status was not a significant marker of mental health symptoms, except for lower substance misuse risk.
Cross-sectionally, greater symptoms across measures were consistently associated with younger age, pre-existing mental health conditions, being a carer, worse financial status, increased sleep irregularity and difficulty since lockdown. Longitudinally, T2 symptoms were consistently associated with worse financial status and increased difficulty sleeping at T1. However, these associations were attenuated when baseline mental health symptoms were adjusted for in the models.
Conclusions
Mental health symptoms were prevalent in a large proportion of young people after the first UK lockdown. Risk factors identified may help characterise high-risk groups for enhanced support and inform interventions.
Integrated pest management (IPM) seeks to minimize the environmental impact of pesticide application, and reduce risks to human and animal health. IPM is based on two important aspects – prevention and monitoring of diseases and insect pests – which today are being assisted by sensing and artificial-intelligence (AI) techniques. In this paper, we surveyed the detection and diagnosis, with AI, of diseases and insect pests, in cotton, which have been published between 2014 and 2021. This research is a systematic literature review. The results show that AI techniques were employed – mainly – in the context of (i) classification, (ii) image segmentation and (iii) feature extraction. The most used algorithms, in classification, were support vector machines, fuzzy inference, back-propagation neural-networks and recently, convolutional neural networks; in image segmentation, k-means was the most used; and, in feature extraction, histogram of oriented gradients, partial least-square regression, discrete wavelet transform and enhanced particle-swarm optimization were equally used. The most used sensing techniques were cameras, and field sensors such as temperature and humidity sensors. The most investigated insect pest was the whitefly, and the disease was root rot. Finally, this paper presents future works related to the use of AI and sensing techniques, to manage diseases and insect pests, in cotton; for instance, implement diagnostic, predictive and prescriptive models to know when and where the diseases and insect pests will attack and make strategies to control them.
Looking for a substantial increase in the reliability and validity of voice analysis measurements in depression, we have developed a new experimental paradigm. The paradigm is based on two vocal tasks with different levels of cognitive processing and a baseline verbal task. It has been applied to 40 subjects, 20 patients with affective disorders and 20 normal individuals. We have found that an important set of vocal parameters, at different intervals, discriminates patients from normal subjects. Here, we discuss four of them – those that have been especially consistent; the patients had longer reaction times, a higher proportion of relative spectral energy (at a very low frequency band), narrower fundamental frequency range and higher proportion of omissions. Under the proposed paradigm, the acoustic analysis could be a promising instrument for the development of quantitative indicators of depression.
Depression is the most prevalent mental disorder in Primary Care (PC), with 60% of depressed patients receiving treatment in PC Units. Suicide is the most serious consequence of depression. The European Commission funded the European Alliance Against Depression (EAAD), a preventive program on depression and suicide that has been applied in 18 European countries. In Spain, this program has been implemented in Catalonia and the Balearic Islands (Majorca and Menorca).
Objectives:
To present the results obtained in the program implementation in Majorca.
Methods:
This program was applied in June 2009 within the urban area of Palma (222,100 inhabitants). Phase 1 entailed data collection of suicide, suicide attempts and antidepressant consumption since 2006. Phase 2 implied the development of specific training courses for General Practitioners on suicide prevention in high-risk population, and the launch of a public advertising campaign with the collaboration of mass media.
Results:
Based on data collected since 2006, there are nearly 300 suicide attempts in the Balearic Islands every year. Within the area of intervention suicide attempts decreased a 24.8% between 2009 and 2010. Conversely, antidepressant prescription and consumption increased from a frequent 2–3% per year to a 5%.
Conclusions:
Obtained results are consistent with findings in other areas where this program has been applied. Data available next years about number of suicides will help to assess the final impact of this program. It is important to continue designing and implementing preventive programs aimed to reduce suicide risk including specific training for health care providers.
Autism spectrum disorders (ASD) are characterized by deficits in social interaction and behavioral impairments. Several studies have reported differences in white matter generalized Fractional Anisotropy (gFA) in ASD.
Objectives
We studied white matter microstructural integrity in individuals with ASD.
Aims
We conducted the first DWI-based whole brain tractography study to compare gFA in 22 deep white matter tracts in first-degree relatives of individuals with ASD to controls and individuals with ASD. Futhermore, we replicated our significants results in an independant sample.
Methods
Fifty-one first-degree relatives of individuals with ASD, 29 controls and 14 individuals with ASD participated.
We performed q-ball imaging whole-brain tractography based on 1.5 T diffusion weighted MRI over 32 non-colinear directions. Then, we computed mean gFA along 22 main deep white matter tracts. A linear mixed model using group, gender, age and IQ as fixed effects and family as a random effect was used and Bonferroni correction applied. We also recruited a replication sample comprising 23 individuals with ASD and 32 controls.
Results
We demonstrated a significantly reduced mean gFA along the left IFOF in first-degree relatives of individuals with ASD and individuals with ASD compared with controls and replicated this finding in an independant sample of patients. A decrease in mean gFA was also observed in the left CST when we compared first-degree relatives of individuals with ASD to controls (no such decrease was present in patients).
Conclusion
Our work suggests that structural fronto-occipital disconnectivity may be an endophenotype of ASD.
Chronic non-malignant pain (CNMP) is defined as pain lasting a minimum of three months. In general, chronic pain affects 20% adult worldwide population. Moreover, pain is more common in patients with depression, anxiety, and substance-use disorders and with low socioeconomic status. We aimed to better understand the influence of pain on substance use and treatment use patterns of individuals who experienced clinically recognized pain and have substance use disorder.
Methods
Patients with pain disturbances were identified in Electronic Health Records (EHR) through ICD-9 code 338*, medical written diagnoses, or diagnoses of fibromyalgia. A patient was considered to have a substance use disorder if he received treatment for illicit drug or alcohol abuse or dependence. We combined 2010–2012 (EHR) data from primary care and specialty mental health setting in a Boston healthcare system (n = 131,966 person-years) and a specialty mental health care setting in Madrid, Spain (n = 43,309 person-years).
Results
We identified that 35.3% of individuals with clinically recognized pain also report substance use disorder, compared to only 10.6% of individuals without clinically recognized pain (P < 0.01). Those with co-morbid pain and substance use disorder were significantly more likely than their specialty care counterparts without co-morbid pain and substance disorders to be seen in the emergency room (56.5% vs. 36.6%, respectively, P < 0.01).
Conclusion
The findings suggest that CNMP is associated with an increase risk of substance abuse disorder.

Ducks are waterfowl belonging to the Anatidae family of cosmopolitan distribution. In duck production systems, obtaining ducklings at one-day-old is determinant for the productive chain. The egg production in some species of ducks reaches about 250 to 300 eggs per year. Obtaining one-day-old ducklings can be done by natural incubation with a broody female duck or artificially in an incubator. During artificial incubation, fertility and hatchability are the most important indicators that must be controlled, because they influence the supply of ducklings to the farm. Many factors are related to fertility and hatching, such as environmental conditions, production system, season, nutrition, management of broodstock, storage time of egg and cleaning of eggs before the incubation. According to some reports, Pekin eggs have greater hatchability than Muscovy eggs. The eggs of Muscovy have presented values lower than 22.7% of hatchability. The hatchability of Pekin duck eggs was 78.0% in the spring, while in summer it was around 46.5%. The best hatchability is observed during the winter (57.68%), as in the summer it decreases to 54.14%. The reproductive characteristics of flocks, age, external and internal quality of the egg, male female relation, and presence of lethal genes are factors that directly involve breeders. Larger sexual ratios between males and females of 1:4.3 to 1: 10 cause reduced egg fertility from 75.9% down to 49.6%. Successful production of day-old ducklings starts with the proper selection and management of breeding stock, proper post-lay handling of fertile eggs and the correct incubation process. There are different methods used to improve the hatchability such as dipping eggs in nutrients during the incubation period.
Neighbourhood greenness or vegetative presence has been associated with indicators of health and well-being, but its relationship to depression in older adults has been less studied. Understanding the role of environmental factors in depression may inform and complement traditional depression interventions, including both prevention and treatment.
Aims
This study examines the relationship between neighbourhood greenness and depression diagnoses among older adults in Miami-Dade County, Florida, USA.
Method
Analyses examined 249 405 beneficiaries enrolled in Medicare, a USA federal health insurance programme for older adults. Participants were 65 years and older, living in the same Miami location across 2 years (2010–2011). Multilevel analyses assessed the relationship between neighbourhood greenness, assessed by average block-level normalised difference vegetative index via satellite imagery, and depression diagnosis using USA Medicare claims data. Covariates were individual age, gender, race/ethnicity, number of comorbid health conditions and neighbourhood median household income.
Results
Over 9% of beneficiaries had a depression diagnosis. Higher levels of greenness were associated with lower odds of depression, even after adjusting for demographics and health comorbidities. When compared with individuals residing in the lowest tertile of greenness, individuals from the middle tertile (medium greenness) had 8% lower odds of depression (odds ratio 0.92; 95% CI 0.88, 0.96; P = 0.0004) and those from the high tertile (high greenness) had 16% lower odds of depression (odds ratio 0.84; 95% CI 0.79, 0.88; P < 0.0001).
Conclusions
Higher levels of greenness may reduce depression odds among older adults. Increasing greenery – even to moderate levels – may enhance individual-level approaches to promoting wellness.
The Centro de Laseres Pulsados in Salamanca, Spain has recently started operation phase and the first user access period on the 6 J 30 fs 200 TW system (VEGA 2) already started at the beginning of 2018. In this paper we report on two commissioning experiments recently performed on the VEGA 2 system in preparation for the user campaign. VEGA 2 system has been tested in different configurations depending on the focusing optics and targets used. One configuration (long focal length $F=130$ cm) is for underdense laser–matter interaction where VEGA 2 is focused onto a low density gas-jet generating electron beams (via laser wake field acceleration mechanism) with maximum energy up to 500 MeV and an X-ray betatron source with a 10 keV critical energy. A second configuration (short focal length $F=40$ cm) is for overdense laser–matter interaction where VEGA 2 is focused onto a $5~\unicode[STIX]{x03BC}\text{m}$ thick Al target generating a proton beam with a maximum energy of 10 MeV and temperature of 2.5 MeV. In this paper we present preliminary experimental results.
Assessing metal contamination of soils has been a difficult task because the metal concentration in soil is not directly correlated to its potential effects. We review an approach, termed the Terrestrial Biotic Ligand Model (TBLM), in which partitioning of metal from soil to soil solution is modelled and the metal in solution interacts with an organism, the biotic ligand, to cause toxicity. The toxicity is modulated by other cations in the soil solution, principally H+, Ca2+, and Mg2+. New results for the model using Ni as the toxic species and barley root elongation as the biological response are presented.
Pigeon pea (PP), Cajanus cajan, is a plant that is cultivated for human food and animal feed. It exists as a wide range of cultivars, and their flexibility for use in animal rearing systems have made PP popular, especially for small-scale farmers. PP is grown widely in India and in parts of Africa and Central America. The main producers of PP in the world are India, Uganda, Tanzania, Kenya, Malawi, Ethiopia, Mozambique, the Dominican Republic, Puerto Rico, the West Indies in the Caribbean and Latin America region, Indonesia and the Philippines and Australia. Analysis has shown that PP contains 17.9-24.3% crude protein (CP) in whole grain, and 21.1-28.1% in split seeds, and high protein genotypes contain 32.5%. Optimal levels of utilisation have been shown to improve broiler performance and may reduce daily feed cost. However, PP contains anti-nutritional factors that negatively affect feed efficiency. The use of processing methods such as fermentation, boiling, milling, soaking, and roasting can minimise any harmful effects and improve its nutritive quality, positively enhancing performance parameters. Studies on the use of PP suggested that it can be included at 7.5% of the diet or as 50% substitution for soybean meal in broiler diets.
In the foothills of the Cumberland Mountains, in central Appalachia (a region that spans 13 states in the US), sits an economically distressed and rural community of the United States. Once a thriving coal-mining area, this region now is reported as one of the hardest places to live in the US. Southeastern Kentucky, located in a remote, rocky, mountainous area surrounded by rivers and valleys and prone to flooding, experienced a major flood in Spring 2013 causing significant damage to homes and critical infrastructure.
Purpose
Aims of the study were to: (1) identify and better understand the contextual variables compounding the impact of a disaster event that occurred in Spring 2013; (2) identify ways participants managed antecedent circumstances, risk, and protective factors to cope with disaster up to 12 months post-event; and (3) further determine implications for community-focused interventions that may enhance recovery for vulnerable populations to promote greater outcomes of adaptation, wellness, and readiness.
Methods
Using an ethnographic mixed-methods approach, an inter-collaborative team conducted face-to-face interviews with (N=12) Appalachian residents about their disaster experience, documented observations and visual assessment of need on an observation tool, and used photography depicting structural and environmental conditions. A Health and Emergency Preparedness Assessment Survey Tool was used to collect demographic, health, housing, environment, and disaster readiness assessment data. Community stakeholders facilitated purposeful sampling through coordination of scheduled home visits.
Results
Triangulation of all data sources provided evidence that the community had unique coping strategies related to faith and spirituality, cultural values and heritage, and social support to manage antecedent circumstances, risk, and protective factors during times of adversity that, in turn, enhanced resilience up to 12 months post-disaster. The community was found to have an innate capacity to persevere and utilize resources to manage and transcend adversity and restore equilibrium, which reflected components of resilience that deserve greater recognition and appreciation.
Conclusion
Resilience is a foundational concept for disaster science. A model of resilience for the rural Appalachia community was developed to visually depict the encompassing element of community-based interventions that may enhance coping strategies, mitigate risk factors, integrate protective factors, and strengthen access. Community-based interventions are recommended to strengthen resilience, yielding improved outcomes of adaptation, health and wellness, and disaster readiness.

Silurian and Devonian bivalves recovered from the Los Espejos (Silurian to Lower Devonian) and Talacasto (Devonian) Formations of the Northern Precordillera Mountain belt are described and illustrated. The fauna comprises some new nuculoids Deceptrix (Devonodeceptrix) jachalensis n. subgen. and n. sp., Nuculites argentinum n. sp., and Anthracoleda (Pseudoleda) minuta n. subgen. and n. sp., as well as the new pterioid Actinopteria modesta n. sp. Additionally, many poorly known South American bivalves are redescribed and figured. Silurian–Devonian pelecypod faunas from some South American localities show differences both in diversity and in faunal composition. Causes for these differences are briefly discussed. Controls other than latitude are suggested in order to explain biogeographical affinities of the studied fauna.
