A 2-year follow-up of the effects of combined binge drinking and cannabis consumption on academic performance and adjustment in Spanish third-year university students.

Introduction: The study was based on 2-year follow-up of the effects of binge drinking and cannabis co-consumption on academic performance and adjustment in Spanish Third-Year University Students and to further explore the impact of academic adjustment on this relationship. Methods: A total of 144 students (aged 19-20 years) enrolled in the third year of university completed the study. The students were recruited during in first academic year (T1) via a survey that included items regarding the use of alcohol (AUDIT-C), cannabis and other drugs and demographic variables. Then, participants meeting the study criteria were then selected and invited by e-mail to a clinical (face-to face) structured interview. The participants completed a calendar of alcohol consumption during the 6 months prior to the interview (Alcohol Timeline Follow back), and recorded cannabis consumption in 3 months prior to the interview. To examine the effects of alcohol and cannabis co-consumption on the outcome variables, we categorized participants into three consumption groups (i.e., control, BD, and BDCA) based on the number of BD days and cannabis unit scores. Results: Binge drinking and cannabis co-consumption in first-year students was significantly associated with poor academic performance and adjustment after 2 years of undergraduate study. Relative to controls, co-consumers (BDCA) reported significantly lower academic and personal-emotional adjustment to university as well as poorer performance. Mediation analysis showed that academic adjustment explains the mechanism by which BDCAs perform less well, mediating the relationship between co-consumption and academic performance, with an indirect effect representing 64.61% of the total effect. Furthermore, the mediating effect of academic adjustment was maintained after controlling for academic adjustment and baseline grade point average (T1). Conclusion: This prospective follow-up study helps to further our knowledge of how combined binge drinking and cannabis consumption may affect university adjustment and academic success in Spanish university students Overall, the study results should encourage health professionals, educational psychologists and academic institutions to take ownership of the need for support and involvement in prevention, as well as for provision of guidelines for implementing appropriate intervention strategies.

Validation of the Spanish version of the student adaptation to college questionnaire (SACQ-50) with Peruvian students.

Objective: To evaluate the psychometric properties of the short version of the Spanish Student Adaptation to College Questionnaire (SACQ-50, Spanish version). Participants: 1513 students from 14 universities in Peru, mainly females (61.5%), aged between 18 and 30 years. Method: Cross-sectional study with the questionnaire administered in person. Confirmatory factorial analysis was conducted to confirm the scale validity. Results: adequate fits were obtained for the multidimensional structure and for the second order factor of the test. Alpha and omega coefficients indicated adequate test reliability. Conclusions: The Spanish version of the SACQ-50 is a multidimensional scale displaying adequate reliability and validity. The scale may be useful for researchers and other professionals working in the university context.

In vitro selection of blackberry (Rubus fruticosus 'Tupy') plants resistant to Botrytis cinerea using gamma ray-irradiated shoot tips.

Blackberry is an economically important crop in Mexico, and its yield is substantially reduced by gray mold, a disease caused by Botrytis cinerea. One of the means to obtain B. cinerea-resistant plants is gamma irradiation. Shoot tips of in vitro-micropropagated blackberry plants (Rubus fruticosus 'Tupy') were irradiated with five doses of Cobalt-60 gamma radiation (0, 15, 30, 45, and 60 Gy) and cultured on Murashige and Skoog basal medium containing 1.0 mg l-1 benzylaminopurine and 0.06 mg l-1 indole-3-butyric acid (MSB medium). After 28 days of culture, survival was evaluated to determine mean lethal dose (LD50), and 200 shoots were further irradiated at the determined LD50 (30.8 Gy). After 28 days, the surviving shoots were micropropagated on MSB medium for 60 days. Non-irradiated shoots were screened for the in vitro selection of resistant B. cinerea, exposing them to different concentrations of sterile culture filtrate of B. cinerea (0, 2, 4, 6, 8, and 10 g l-1) for 28 days to determine mean lethal concentration (LC50), and the irradiated surviving shoots were further exposed to the determined LC50 (4.6 g l-1). Three surviving lines (rfgum5, rfgum6, and rfgum17) that did not present changes compared with the control shoots were micropropagated to obtain plantlets, which were further subjected to in vitro resistance assays using detached leaves inoculated with B. cinerea (1×103 spores ml-1). Plants of rfgum5 and rfgum6 mutant lines were highly resistant and presented similar growth to control plants. Therefore, this methodology is useful to obtain B. cinerea-resistant blackberry plants.

Barriers and Solutions to Improve Therapeutic Adherence from the Perspective of Primary Care and Hospital-Based Physicians.

Purpose: To identify the barriers affecting treatment adherence in patients with chronic disease and to determine solutions through the physician's opinion of primary care and hospital settings. Methods: An observational study using the nominal group technique was performed to reach a consensus from experts. A structured face-to-face group discussion was carried out with physicians with more than 10 years of experience in the subject of treatment adherence/compliance in either the primary care setting or the hospital setting. The experts individually rated a list of questions using the Likert scale and prioritized the top 10 questions to identify barriers and seek solutions afterward. The top 10 questions that obtained the maximum score for both groups of experts were prioritized. During the final discussion group, participating experts analyzed the prioritized items and debated on each problem to reach consensual solutions for improvement. Results: A total of 17 professionals experts participated in the study, nine of them were from a primary care setting. In the expert group from the primary care setting, the proposed solution for the barrier identified as the highest priority was to simplify treatments, measure adherence and review medication. In the expert group from the hospital setting, the proposed solution for the barrier identified as the highest priority was training on motivational clinical interviews for healthcare workers undergraduate and postgraduate education. Finally, the expert participants proposed implementing an improvement plan with eight key ideas. Conclusion: A consensual improvement plan to facilitate the control of therapeutic adherence in patients with chronic disease was developed, taking into account expert physicians' opinions from primary care and hospital settings about barriers and solutions to address therapeutic adherence in patients with chronic disease.

A new animal model of atrophy-hypertrophy complex and liver damage following Yttrium-90 lobar selective internal radiation therapy in rabbits.

Lobar selective internal radiation therapy (SIRT) is widely used to treat liver tumors inducing atrophy of the treated lobe and contralateral hypertrophy. The lack of animal model has precluded further investigations to improve this treatment. We developed an animal model of liver damage and atrophy-hypertrophy complex after SIRT. Three groups of 5-8 rabbits received transportal SIRT with Yttrium 90 resin microspheres of the cranial lobes with different activities (0.3, 0.6 and 1.2 GBq), corresponding to predicted absorbed radiation dose of 200, 400 and 800 Gy, respectively. Another group received non-loaded microspheres (sham group). Cranial and caudal lobes volumes were assessed using CT volumetry before, 15 and 30 days after SIRT. Liver biochemistry, histopathology and gene expression were evaluated. Four untreated rabbits were used as controls for gene expression studies. All animals receiving 1.2 GBq were euthanized due to clinical deterioration. Cranial SIRT with 0.6 GBq induced caudal lobe hypertrophy after 15 days (median increase 34% -ns-) but produced significant toxicity. Cranial SIRT with 0.3 GBq induced caudal lobe hypertrophy after 30 days (median increase 82%, p = 0.04). No volumetric changes were detected in sham group. Transient increase in serum transaminases was detected in all treated groups returning to normal values at 15 days. There was dose-dependent liver dysfunction with bilirubin elevation and albumin decrease. Histologically, 1.2 GBq group developed permanent severe liver damage with massive necrosis, 0.6 and 0.3 GBq groups developed moderate damage with inflammation and portal fibrosis at 15 days, partially recovering at 30 days. There was no difference in the expression of hepatocyte function and differentiation genes between 0.3 GBq and control groups. Cranial SIRT with 0.3 GBq of 90Y resin microspheres in rabbits is a reliable animal model to analyse the atrophy-hypertrophy complex and liver damage without toxicity.

The Role of Arabinogalactan Type II Degradation in Plant-Microbe Interactions.

Arabinogalactans (AGs) are structural polysaccharides of the plant cell wall. A small proportion of the AGs are associated with hemicellulose and pectin. Furthermore, AGs are associated with proteins forming the so-called arabinogalactan proteins (AGPs), which can be found in the plant cell wall or attached through a glycosylphosphatidylinositol (GPI) anchor to the plasma membrane. AGPs are a family of highly glycosylated proteins grouped with cell wall proteins rich in hydroxyproline. These glycoproteins have important and diverse functions in plants, such as growth, cellular differentiation, signaling, and microbe-plant interactions, and several reports suggest that carbohydrate components are crucial for AGP functions. In beneficial plant-microbe interactions, AGPs attract symbiotic species of fungi or bacteria, promote the development of infectious structures and the colonization of root tips, and furthermore, these interactions can activate plant defense mechanisms. On the other hand, plants secrete and accumulate AGPs at infection sites, creating cross-links with pectin. As part of the plant cell wall degradation machinery, beneficial and pathogenic fungi and bacteria can produce the enzymes necessary for the complete depolymerization of AGs including endo-ß-(1,3), ß-(1,4) and ß-(1,6)-galactanases, ß-(1,3/1,6) galactanases, α-L-arabinofuranosidases, ß-L-arabinopyranosidases, and ß-D-glucuronidases. These hydrolytic enzymes are secreted during plant-pathogen interactions and could have implications for the function of AGPs. It has been proposed that AGPs could prevent infection by pathogenic microorganisms because their degradation products generated by hydrolytic enzymes of pathogens function as damage-associated molecular patterns (DAMPs) eliciting the plant defense response. In this review, we describe the structure and function of AGs and AGPs as components of the plant cell wall. Additionally, we describe the set of enzymes secreted by microorganisms to degrade AGs from AGPs and its possible implication for plant-microbe interactions.

Genealogical relationship inference to identify areas of intensive poaching of the Orange-fronted Parakeet (Eupsittula canicularis).

BACKGROUND: The Orange-fronted Parakeet (Eupsittula canicularis) is the Mexican psittacine that is most captured for the illegal pet trade. However, as for most wildlife exploited by illegal trade, the genetic diversity that is extracted from species and areas of intensive poaching is unknown. In this study, we analyzed the genetic diversity of 80 E. canicularis parakeets confiscated from the illegal trade and estimated the level of extraction of genetic diversity by poaching using the mitochondrial DNA sequences of cytochrome b (Cytb). In addition, we analyzed the genealogical and haplotypic relationships of the poached parakeets and sampled wild populations in Mexico, as a strategy for identifying the places of origin of poached parakeets. RESULTS: Poached parakeets showed high haplotype diversity (Hd = 0.842) and low nucleotide diversity (Pi = 0.00182). Among 22 haplotypes identified, 18 were found exclusively in 37 individuals, while four were detected in the remaining 43 individuals and shared with the wild populations. A rarefaction and extrapolation curve revealed that 240 poached individuals can include up to 47 haplotypes and suggested that the actual haplotype richness of poached parakeets is higher than our analyses indicate. The geographic locations of the four haplotypes shared between poached and wild parakeets ranged from Michoacan to Sinaloa, Mexico. However, the rare haplotypes detected in poached parakeets were derived from a recent genetic expansion of the species that has occurred between the northwest of Michoacan and the coastal region of Colima, Jalisco and southern Nayarit, Mexico. CONCLUSIONS: Poached parakeets showed high genetic diversity, suggesting high extraction of the genetic pool of the species in central Mexico. Rarefaction and extrapolation analyses suggest that the actual haplotype richness in poached parakeets is higher than reflected by our analyses. The poached parakeets belong mainly to a very diverse genetic group of the species, and their most likely origin is between northern Michoacan and southern Nayarit, Mexico. We found no evidence that poachers included individuals from Central American international trafficking with individuals from Mexico in the sample.

Experiences of pregnancy in adolescence of internally displaced women in Bogotá: an ethnographic approach.

BACKGROUND: Pregnancy in adolescence is higher among internally displaced women in Colombia than non-displaced women. It is defined as a problem with significant negative outcomes by both biomedical and epidemiological approaches. However, little is known about pregnancy during adolescence from the perspective of women who experienced this in the specific context of armed conflict and displacement. AIM: This article focuses on how internally displaced women understand their experiences of pregnancy in adolescence in the context of armed conflict through an ethnographic approach in a receptor community of internally displaced women in Bogotá, Colombia. METHODS: Based on 10 years of experience in the community, we conducted 1 year of fieldwork, using an ethnographic approach. We collected life stories of 20 internally displaced women through in-depth interviews and ran 8 workshops with them and other women from the community. We used thematic analysis to analyse the responses of internally-displaced women and understand how they made meaning around their experiences of adolescent pregnancy in the context of displacement. RESULTS: The main themes that emerged from participants' experiences include rural violence, early family life (characterized by violence and mistreatment at home), meanings of pregnancy at an early age (including being challenged and feelings of love), and reactions to their pregnancies during adolescence (such as stigmatization) from their families and partners. CONCLUSION: Our analysis of the in-depth interviews and the workshops suggests that adolescent pregnancy among women who are internally displaced has complex dynamics, characterized by the violent context of the rural areas, but primarily by the violence experienced during their childhood. The experience of pregnancy during adolescence brings feelings of ownership and also challenges, together with the forced displacement. This understanding will provide insights for policy makers and healthcare providers on how to work with this specific population who have experienced pregnancy in adolescence.

Rebound after discontinuation of teriflunomide in patients with multiple sclerosis: 2 case reports.

Teriflunomide is an oral first-line disease modifying treatment (DMT) for patients with relapsing-remitting multiple sclerosis (RRMS). It can take up to two years to achieve systemic clearance of teriflunomide to an acceptable level, but this washout period may be accelerated by administration of cholestyramine. Relapse of multiple sclerosis (MS) during washout of teriflunomide or other first-line DMT is not as common. We report two patients with RRMS who experienced a relapse after the accelerated elimination period (AEP) of teriflunomide and confirmation of negative plasmatic levels (<0.02 µg/ml). In cases of risk of MS activity, we should not wait for teriflunomide negative plasmatic levels confirmation before starting the next DMT to reduce the risk of relapse.

Binge Drinking, Cannabis Co-Consumption and Academic Achievement in First Year University Students in Spain: Academic Adjustment as a Mediator.

Little is known about how binge drinking or the combination of binge drinking and cannabis consumption affect academic achievement in students during the transition to university, or about the mechanisms that mediate this relationship. The purpose of this study was to evaluate the association between this pattern of alcohol/cannabis consumption and academic achievement, considering academic adjustment as a possible mediator. A total of 258 Spanish, first-year university students (145 females and 113 males), enrolled in undergraduate degree courses, were categorized into three groups on the basis of their patterns of alcohol/cannabis consumption: control, binge drinkers and co-consumers. The findings showed a significant effect of the combined binge drinking/cannabis consumption, but not of binge drinking alone, upon academic achievement and academic adjustment. Grade point average (GPA) and academic adjustment were lower in the co-consumers than in the other groups. Regarding the mediation effect, 34.33% of the impact of combined alcohol/cannabis use on GPA was mediated by academic adjustment. The combined consumption of alcohol and cannabis led to difficulties in adaptation to academic life, which in turn contributed to poorer performance at university. The implications of the findings are discussed.

Altered individual behavioral and EEG parameters are related to the EDSS score in relapsing-remitting multiple sclerosis patients.

Functional neuroanatomy of cognitive impairment in multiple sclerosis is currently still a challenge. During the progression of the disease, several cognitive mechanisms deteriorate thus diminishing the patient's quality of life. A primary objective in the cognitive assessment of multiple sclerosis (MS) patients is to find reliable measures utilizing diverse neuroimaging techniques. Moreover, especially relevant in the clinical environment is finding technical approaches that could be applied to individual participants and not only for group analysis. A 64-channel electroencephalographic recording (EEG) was made with thirty participants divided into three groups of equivalent size (N = 10) (healthy control, low-EDSS (1-2.5) and moderate-EDSS (4-6)). Correlation analysis was applied to multiple measures: behavior, neuropsychological tests (Paced Auditory Serial Addition Test, 3 seconds (PASAT-3s) and the Symbol Digit Modality Test (SDMT)), Expanded Disability Status Scale (EDSS), even-related potential (P3) and event-related desynchronization (ERD) parameters and the correlation scores between individual participant's P3/ERD maps and the healthy grand average P3/ERDmaps. Statistical analysis showed that diverse parameters exhibited significant correlations. A remarkable correlation was the moderate score found between SDMT and EDSS (r = -0.679, p = 0.0009). However, the strongest correlation was between the value of integrated measures (reaction time, P3 and ERD latency) and EDSS (r = 0.699, p = 0.0006). In regard to correlations for grand average maps between groups, the P3 component exhibited a lower score according to a more deteriorated condition (higher EDSS). In contrast, ERD maps remained stable with an increase of EDSS. Lastly, a Z-transformation of individual values of all variables included in the study exhibited heterogeneity in cognitive alterations in the multiple sclerosis participants.

'We just been forced to do it': exploring victimization and agency among internally displaced young mothers in Bogotá.

BACKGROUND: Armed conflict in Colombia has a history of 50 years that continues to this day. According to the Victims Record of Colombia, from 1985 to 2013 2.683.335 women have been victims of the armed conflict. Women have been described as the main victims of the armed conflict, especially in the Colombian cultural context that in some regions is still considered to be a 'machista' and patriarchal one. In contrast, some authors have explicitly stressed Colombian women's agency instead of positioning them only as victims. Some of them are described as 'survivors' of the war, emphasizing their impressive resistance to the outcomes of war and forced displacement. In contrast to the background of these scholarly discussions, our study focused on how displaced women living in Bogotá themselves articulate their experiences of agency and victimization. This paper will therefore explore how women, in reconstructing their life stories, expressed the tussles between victimization and agency. METHODS: We used qualitative methods conducted within an ethnographic approach. Based on ten years of experience in the neighborhood and one year of fieldwork, we collected the life stories of twenty internally displaced mothers, and ran eight workshops with them. We analyzed the narratives with a specific focus on how women expressed victimization and agency in four important periods in their life that related to the process of displacement: when they left home, when they became pregnant, when they were forced to leave their towns, and when they arrived in Bogotá. RESULTS: Participants' life stories showed how they struggled with agency during their lives. They were victims of abuse and violence during childhood and finally decided to leave their homes. They decided to have their babies despite the fact that they were abandoned by their partners and families, and after doubts about and attempts to have an abortion. Throughout the process of displacement the participants had been engaged in ambiguous relationships with armed groups. Finally they arrived in Bogotá and faced adverse circumstances but were looking for better opportunities for them and their children. CONCLUSION: The analysis of how internally displaced women narrated their life stories showed us that the concepts that dominate scholarly debates about agency, victimization and survivorship do not do justice to the life stories of the participants in our study. These stories show that changes with a major impact were loaded with ambiguity and were characterized by helplessness, lack of control and agency simultaneously. The reconstruction of these life stories goes beyond the stereotype of displaced women as only 'victims', but points also to their agency and courageous decisions they made in contexts that were not controlled by them and where support was often lacking. Instead of label them, it is important to understand the complexity of the life experiences of IDW, in order to build policies that offer them aids as victims, but also build policies and intervention programs that empower them as agents in order to support them during resettlement.

Consequences on economic outcomes of generic versus brand-name drugs used in routine clinical practice: the case of treating peripheral neuropathic pain or generalized anxiety disorder with pregabalin.

BACKGROUND: Discrepancies are seen between arguments in favor of and against prescribing generic versus brand-name drugs. OBJECTIVE: To provide real-world evidence on treatment persistence, economic and clinical outcomes of pregabalin, generic versus brand-name (Lyrica®, Pfizer), routinely used to treat neuropathic pain (NP) or generalized anxiety disorder (GAD). METHODS: Electronic medical records from subjects' first starting treatment with pregabalin between January-2015 and June-2016 were analyzed. Persistence, resources utilization, and costs were assessed, along with remitter and responder rates. RESULTS: A total of 4860 records were analyzed. Discontinuation was lower with brand-name than with generic in NP (adjusted hazard ratio [HR]: 0.70 [95% CI: 0.58-0.85], p < 0.001) and GAD patients (HR: 0.63 [0.45-0.84], p < 0.001). Adjusted mean total costs were lower with brand-name: €1500 [1428-1573] vs. €2003 [1864-2143] in NP and €1528 [1322-1734] vs. €2150 [1845-2454] in GAD (both p < 0.001). More patients were remitters/ responders with brand-name in NP (55.0% vs. 46.7% and 59.2% vs. 48.4%, respectively; p < 0.001) and GAD (58.6% vs. 48.7% and 64.6% vs. 47.2%, respectively; p < 0.001). CONCLUSIONS: As a consequence of higher persistence in routine practice, patients who first started therapy with pregabalin brand-name versus generic showed better pain or anxiety outcomes at a lower cost to payers in Spain.

El 56% de los participantes experimentaron angustia ante la ocurrencia de tales conductas o actitudes, el 50% tristeza y el 49% enojo. Se encontraron diferencias entre las emociones más experimentadas por los hombres y mujeres de la muestra; también en lo que respecta a las conductas o actitudes que refieren recibir de parte de sus parejas hacia ellas o ellos. Conclusiones: las conductas o actitudes de la violencia psicológica en las relaciones de noviazgo han afectado a los participantes;y este tipo de violencia es considerado, mayormente, problema social y en menor medida como un problema de pareja..(AU)

Objective: to describe the characteristics of psychological violence in university students ´ courtship, with respect to their perception, modalities, and response to it, in students of the Psychology Faculty of the Universidad del Aconcagua. Materials and methods: quantitative research, descriptive study, cross-sectional design with surveys. The intentional sample was integrated by 452 students from two careers: Psychology and Childhood, Adolescence and Family, of both sexes, with an average age of 22 years old, that had maintained or were maintaining a courtship. Instrument: The Psychological Violence Questionnaire in courtships (Marchiori, Lucientes de Funes,Puente de Camaño and Bordón, 2013). Results: presence, in a variety of frequencies that goes from occasionally to always, of twenty three attitudes or behaviors related to psychological violence. The most frequent behavior reported by the participants was oppositions (72,1%) and the less frequent was death threat (3,1%). The 56% of participants experienced anguish because of this kind of behaviors, 50% sadness and 49% anger. Remarkable differences were found between the emotions experienced by men and women of the sample; and also in respect to the behavior and attitudes they received from their partners. Conclusions: the behaviors or attitudes related to psychological violence have affected the participants, and this type of violence is considered, mostly, as a social problem, and in a lower rate as a courtships´problem..(AU)

Adipose-derived mesenchymal stem cells (AdMSC) for the treatment of secondary-progressive multiple sclerosis: A triple blinded, placebo controlled, randomized phase I/II safety and feasibility study.

BACKGROUND: Currently available treatments for secondary progressive multiple sclerosis(SPMS) have limited efficacy and/or safety concerns. Adipose-mesenchymal derived stem cells(AdMSCs) represent a promising option and can be readily obtained using minimally invasive procedures. PATIENTS AND METHODS: In this triple-blind, placebo-controlled study, cell samples were obtained from consenting patients by lipectomy and subsequently expanded. Patients were randomized to a single infusion of placebo, low-dose(1x106cells/kg) or high-dose(4x106cells/kg) autologous AdMSC product and followed for 12 months. Safety was monitored recording adverse events, laboratory parameters, vital signs and spirometry. Expanded disability status score (EDSS), magnetic-resonance-imaging, and other measures of possible treatment effects were also recorded. RESULTS: Thirty-four patients underwent lipectomy for AdMSCs collection, were randomized and thirty were infused (11 placebo, 10 low-dose and 9 high-dose); 4 randomized patients were not infused because of karyotype abnormalities in the cell product. Only one serious adverse event was observed in the treatment arms (urinary infection, considered not related to study treatment). No other safety parameters showed changes. Measures of treatment effect showed an inconclusive trend of efficacy. CONCLUSION: Infusion of autologous AdMSCs is safe and feasible in patients with SPMS. Larger studies and probably treatment at earlier phases would be needed to investigate the potential therapeutic benefit of this technique.

Cost of treating peripheral neuropathic pain with pregabalin or gabapentin at therapeutic doses in routine practice.

AIM: To analyze the cost of peripheral neuropathic pain (PNP) treatment with pregabalin or gabapentin at therapeutic doses in routine clinical practice. METHODS: Analysis of a retrospective, observational study of electronic medical records of patients treated for PNP with therapeutic doses of pregabalin or gabapentin, with 2 years' follow-up, considering PNP type, comorbidities, concomitant analgesia and resource use. RESULTS: The weighted total average cost/patient was lower for pregabalin than gabapentin (€2464 [2197-2730] vs €3142 [2670-3614]; p = 0.014) due to significantly lower both healthcare and non-healthcare costs. This is explained by a significantly lower use of concomitant analgesia, fewer primary care visits and fewer days of sick leave. CONCLUSION: At therapeutic doses, pregabalin was found to have lower healthcare and non-healthcare costs than gabapentin in routine practice.

Evolutionary history of Mexican domesticated and wild Meleagris gallopavo.

BACKGROUND: The distribution of the wild turkey (Meleagris gallopavo) extends from Mexico to southeastern Canada and to the eastern and southern regions of the USA. Six subspecies have been described based on morphological characteristics and/or geographical variations in wild and domesticated populations. In this paper, based on DNA sequence data from the mitochondrial D-loop, we investigated the genetic diversity and structure, genealogical relationships, divergence time and demographic history of M. gallopavo populations including domesticated individuals. RESULTS: Analyses of 612 wild and domesticated turkey mitochondrial D-loop sequences, including 187 that were collected for this study and 425 from databases, revealed 64 haplotypes with few mutations, some of which are shared between domesticated and wild turkeys. We found a high level of haplotype and nucleotide diversity, which suggests that the total population of this species is large and stable with an old evolutionary history. The results of genetic differentiation, haplotype network, and genealogical relationships analyses revealed three main genetic groups within the species: mexicana as a population relict (C1), merriami (C2), and mexicana/intermedia/silvestris/osceola (C3). Haplotypes detected in domesticated turkeys belong to group C3. Estimates of divergence times agree with range expansion and diversification events of the relict population of M. gallopavo in northwestern Mexico during the Pliocene-Pleistocene and Pleistocene-Holocene boundaries. Demographic reconstruction showed that an expansion of the population occurred 110,000 to 130,000 years ago (Kya), followed by a stable period 100 Kya and finally a decline ~ 10 Kya (Pleistocene-Holocene boundary). In Mexico, the Trans-Mexican Volcanic Belt may be responsible for the range expansion of the C3 group. Two haplotypes with different divergence times, MGMDgoB/MICH1 and MICH2, are dominant in domesticated and commercial turkeys. CONCLUSIONS: During the Pleistocene, a large and stable population of M. gallopavo covered a wide geographic distribution from the north to the center of America (USA and Mexico). The mexicana, merriami, and mexicana/intermedia/silvestris/osceola genetic groups originated after divergence and range expansion from northwestern Mexico during the Pliocene-Pleistocene and Pleistocene-Holocene boundaries. Old and new maternal lines of the mexicana/intermedia/silvestris/osceola genetic group were distributed within the Trans-Mexican Volcanic Belt where individuals were captured for domestication. Two haplotypes are the main founder maternal lines of domesticated turkeys.

Estudio de las actitudes hacia la ética profesional en estudiantes de grado y posgrado de psicología / Study of attitudes towards professional ethics in undergraduate and graduate students of psychology

El objetivo del estudio es realizar un relevamiento y estudio sobre las actitudes hacia la ética en estudiantes de grado y posgrado de psicología. A fin de comparar competencias más valoradas y menos valoradas en cuanto a ética profesional, se aplica a una muestra intencional (n=273) de estudiantes de grado (n=193) y posgrado (n=80) la Escala sobre Actitudes hacia la Ética Profesional (Hirsch Adler, 2005, adaptación de Ormart, Esteva y Navés, 2012), cuenta con 55 proposiciones que miden 4 competencias: cognitivo-técnicas, sociales, éticas y afectivo-emocionales. Los resultados obtenidos evidencian que, tanto para los estudiantes de grado como de posgrado, la competencia más valorada es la de ética y no se presentan grandes diferencias en el resto de las competencias.

The present investigation has as objective to make a survey and a study of the attitudes from grade and postgraduate students of the Faculty of Psychology at the University of Aconcagua (UDA), in what regards to professional ethic. With the purpose of being able to compare between the grade and postgraduate students, the most valued competences and those less valued towards professional ethic are weighted, it has been applied to an intentional sample: 193 volunteer students from grade and 80 from postgraduate level, The Ethical Attitudes Scale (Hirsch Adler, 2005, adaptation by Ormart, Esteva y Navés, 2012), which consists of 55 propositions relating to four skills: technical-cognitive, socials, ethics and affective-emotional. The results obtained in this research show that for both, grade and postgrad students, the most valued skill is Ethics and in the rest of the competences there are not major differences.

Evolutionary Analysis of Pectin Lyases of the Genus Colletotrichum.

Pectin lyases (PNLs) are important enzymes that are involved in plant cell wall degradation during the infection process. Colletotrichum is a diverse genus of fungi, which allows the study of the evolution of PNLs and their possible role in pathogen-host interactions and lifestyle adaptations. The phylogenetic reconstruction of PNLs from Colletotrichum and analysis of selection pressures showed the formation of protein lineages by groups of species with different selection pressures and specific patterns. The analysis of positive selection at individual sites using different methods allowed for the identification of three codons with evidence of positive selection in the oligosaccharide-binding region and two codons on the antiparallel sheet, which may influence the interaction with the substrate. Seven codons on the surface of the protein, mainly in the peripheral helices of the PNLs, could have an important function in evasion of plant defenses, as has been proposed in other enzymes. According to our results, it is possible that events of genetic duplication occurred in ancestral lines, followed by episodes of genetic diversification and gene loss, probably influenced by differences in the composition of the host cell wall. Additionally, different patterns of evolution in Colletotrichum appear to be molded by a strong purifying selection and positive selection episodes that forged the observed evolutionary patterns, possibly influenced by host interaction or substrate specificity. This work represents a starting point for the study of sites that may be important for evasion of plant defenses and biotechnological purposes.
