Inbreeding depression in castor bean (Ricinus communis L.) progenies

O objetivo do trabalho foi investigar a depressão endogâmica (DE) na mamoneira, espécie de reprodução sexuada mista. de uma população derivada da cultivar Guarani, amostraram-se 60 plantas-mãe. de cada uma foram obtidos três tipos de progênies: de autofecundação (AU), de cruzamentos obrigatórios (CR) e de polinização livre (PL). A produtividade de grãos das progênies for avaliada por meio de experimentos em blocos incompletos em dois locais. Houve forte interação de progênies x locais o que levou a obter estimativas dentro de cada local. Verificou-se ampla variação na depressão endogâmica, com médias de 6,7% e 13,4%, comparando-se as progênies AU com as PL. Verificou-se que a população tem alto potencial para selecionar linhagens promissoras. Foi baixa a freqüência de plantas-mãe gerando progênies com alta capacidade geral de combinação e baixa depressão endogâmica, simultaneamente. Seleção recorrente aumentará a ocorrência de genitoras associando essas duas propriedades, necessárias para obtenção de variedades sintéticas superiores.

Depression in patients with Parkinson's disease: Impact on functioning

Depression is a frequently observed neuropsychiatric phenomenon in Parkinson's disease (PD) and it has been lately considered as a manifestation of such disease. The aim of the study was to investigate the relationship between depression and clinical aspects of PD and to assess the impact of the co-occurrence of such condition on the burden imposed by PD. Fifty Outpatients diagnosed with idiopathic PD according to the London Brain Bank criteria were examined. PD was evaluated using Hoehn & Yahr staging (H&Y), United Parkinson's Disease Rating Scale (UPDRS) and Schwab & England (S&E) functional capacity evaluation. A semi-structured clinical interview was used. The diagnosis of PD was made by neurologist experts on movement disorders, and the diagnosis of depression was trade by a psychiatrist, according to the ICD-10 diagnostic criteria. Depressive symptoms were additionally measured using the Montgomery-Asberg Depression Scale. The analysis of quantitative data was performed using descriptive statistics, Univariate linear regression, T-Student Test and ANOVA. Seventeen (34%) patients were diagnosed as clinically depressed and, when compared to the non-depressed ones, presented the following results: H&Y: 3.2 vs. 2.8; UPDRS total: 75.7 vs. 65.3; S&E: 53.5% vs. 65.8% and PD duration: 114.4 months vs. 125.8 months. Depressed patients showed more advanced staging (H&Y), a more severe global clinical condition (UPDRS) and also a greater decrease in their functional capacity (S&E). These data reinforce the hypothesis that depression is associated to poorer functioning in patients with PD. (C) 2008 Elsevier B.V All rights reserved.

Dynamics of follicle populations and gonadotropin concentrations in fillies age two to ten months

Follicle populations and concentrations of circulating gonadotropins were studied during age 2-10 months in 10 spring-born pony fillies. Blood sampling and ultrasound scanning were done every 4 days and daily for four 30 day periods. During 5-12 weeks, FSH concentrations were lower in 6 fillies with follicles greater than or equal to 6 mm (mean +/- s.e. 1.4 +/- 0.1 ng/ml) than in 4 fillies with follicles <6 mm (2.8 + 0.3 ng/ml). The diameters and numbers of follicles and gonadotropin concentrations increased progressively during age 2-4 months. A plateau in follicle activity and reduced levels of gonadotropins occurred during 5-7 months. During 8-10 months, follicles grew to >10 mm and gonadotropin concentrations increased. Waves of follicular growth were identified during the 30 day periods by significant increases in the diameter of the 10 largest follicles. The waves did not partition into dominant and subordinate follicles. Results indicated an initial postnatal period of negative ovarian feedback, temporally related changes in gonadotropins and follicles for months 3-10, and development of follicles in waves.

Comorbid major depression in obsessive-compulsive disorder patients

Although major depressive disorder (MDD) has been consistently considered the most frequent complication of obsessive-compulsive disorder (OCD), little is known about the clinical characteristics of patients with both disorders. This study assessed 815 Brazilian OCD patients using a comprehensive psychiatric evaluation. Clinical and demographic variables, including OCD symptom dimensions, were compared among OCD patients with and without MDD. Our findings showed that prevalence rates of current MDD (32%) and lifetime MDD (67.5%) were similar for both sexes in this study. In addition, patients with comorbid MDD had higher severity scores of OCD symptoms. There was no preferential association of MDD with any particular OCD symptom dimension. This study supports the notion that depressed OCD patients present more severe general psychopathology. © 2011 Elsevier Inc. All rights reserved.

Health-related quality of life and depression in patients with dentofacial deformity

Introduction: Patients with dentofacial deformities present difficulties at work and in social adaptation. At the same time, they often appear depressed, and as a consequence, the psychosocial aspects of surgery play an important role. The aim of this study was to investigate the effects that depression causes in the quality of life of patients with dentofacial deformity. Material and methods: Filthy patients were recruited 1 year before undergoing orthognathic surgery and correlated oral and general health with the presence and absence of depression. In order to accomplish this, these patients received an adapted questionnaires of quality of life and Beck Depression Inventory to fill out. Fisher's test was applied, with a significance level of 5 %. Intercooled Stata version 9.0 was used to analyze data. Results: Among the eight domains of quality of life, there were three associated with depression status: vitality (p < 0.001), social aspects (p = 0.011), and mental health (p = 0.008). Discussion: There is growing interest in the impact of dentofacial deformity conditions on patients' quality of life. The scientific literature has discussed the social aspects of these deformities and showed that untreated patients had low self-esteem and suffered social restrictions before making the orthodontic and surgical treatments. This study concluded that the depression interferes significantly in vitality, social aspects of the individual, and mental health and, at the same time, emphasizes that the orthognathic surgery aims to not only restore esthetics and function to the patient but also improve the quality of life. © 2012 Springer-Verlag.

Anxiety and depression in brazilian undergraduate students: the role of sociodemographic variables, undergraduate course characteristics and social skills

The prevalence of anxiety and depression disorders in undergraduate students is high and several variables can be influential. The aim is to verify the predictive value of social skills, sociodemographic variables, and course characteristics for depression and anxiety. A total of 1282 students of a public university, of both sexes and from different years and courses, participated in this study. Screening instruments for depression and anxiety were applied, as well as an instrument investigating social skills and a questionnaire covering socio demographic indicators and course characteristics. The data were analyzed using univariate analysis followed by multiple binary regression analysis in order to define the relevance of these depression and anxiety measures. The rates of anxiety and depression were 19.4% and 3.8%, respectively. The social skills and living situation were predictive of depression, with the social skills and course area (with higher prevalence for the exact and human sciences) remaining in the final model for anxiety. Such data have implications for psychological prevention and intervention with this population.
