Trichoderma spp. decrease Fusarium root rot in common bean

The effectiveness of six Trichoderma-based commercial products (TCP) in controlling Fusarium root rot (FRR) in common bean was assessed under field conditions. Three TCP, used for seed treatment or applied in the furrow, increased seedling emergence as much as the fungicide fludioxonil. FRR incidence was not affected, but all TCP and fludioxonil reduced the disease severity, compared to control. Application of Trichoderma-based products was as effective as that of fludioxonil in FRR management.

Limitations in controlling white mold on common beans with Trichoderma spp. at the fall-winter season

We studied the effectiveness of application of Trichoderma spp. in controlling white mold on common beans at the fall-winter crop in the Zona da Mata region of the State of Minas Gerais, Brazil. There was no effect of the antagonist in reducing the disease severity, which could be explained by the low temperatures and the high inoculum pressure in the field. We concluded that Trichoderma applications are not recommended for control of white mold on common beans at the fall-winter season in regions with average temperature bellow 20 °C, since this condition favor more the pathogen than the antagonist.

Knowledge of common pediatric cancers among medical students in northeast Brazil

BACKGROUND: In recent decades, early diagnosis of childhood cancer has taken an important place on the international agenda. The authors of this study evaluated a group of medical students in Recife, Brazil, regarding knowledge and practices related to early diagnosis of common childhood cancers. METHODS: Cross-sectional study with a sample of 82 medical students, from a total of 86 eligible subjects. Data were collected using self-completed questionnaires. Subgroups were defined according to knowledge of the theme and students' perceptions of their own skills and interest in learning. RESULTS: 74.4% of the sample demonstrated a minimum level of knowledge. The group without minimum knowledge or self-perceived competence to identify suspected cases (23.3%) was in the worst position to perform early diagnosis. All subjects expressed interest in learning more about this topic. CONCLUSIONS: Despite acceptable levels of knowledge among these medical students, the definition of central aspects of the teaching and learning processes would be useful for training physicians with the skills for diagnosing and treating pediatric cancers

The Role of Knowledge Management in Developing Common Business Mindset in a Firm

Yrityksen yhteisellä liiketoimintanäkemyksellä tarkoitetaan organisaation kykyä ymmärtää liiketoiminnan olennaiset elementit, ja varmistaa, että työntekijöillä ja yrityksen asiakkailla on positiivinen ja yhdenmukainen kuva ja kokemus kyseisestä organisaatiosta. Tämän Pro-gradu – tutkielman tuloksena kehitettiin mittari, jolla yhteisen liiketoimintanäkemyksen tilaa voidaan yrityksessä mitata. Lisäksi tutkielma selvittää tietojohtamisen merkitystä yhteisen liiketoimintanäkemyksen kehityksessä. Tutkimusaineisto kerättiin Internet -kyselytutkimuksella, johon saatiin 158 vastausta. Aineisto analysoitiin tilastollisilla menetelmillä. Tutkimustulokset viittaavat vahvasti siihen, että tiedon jakamisella ja verkostoitumisella on tilastollisesti merkittävä vaikutus yhteisen liiketoimintanäkemyksen kehittymisessä. Tästä syystä yritysten tulisi integroida tietojohtamisen periaatteet strategioihinsa ja luoda systemaattinen malli, joka kannustaa organisaatiota tiedon jakamiseen ja verkostoitumiseen.

Crescimento e qualidade de mudas de Senna macranthera (collad.)irwin et barn. em resposta à calagem

Este trabalho foi desenvolvido com o objetivo de verificar a influência da saturação por bases do substrato no crescimento inicial e qualidade de mudas de Senna macranthera (fedegoso). O delineamento utilizado foi em blocos ao acaso com quatro repetições por tratamento. Como substrato foram empregados três diferentes solos, sendo para cada um deles a saturação por bases original elevada para os seguintes valores: Argissolo Vermelho-Amarelo 50, 60 e 70%, Latossolo Vermelho-Amarelo distrófico 30, 50 e 70% e Latossolo Vermelho-Amarelo álico 25, 45 e 65%. Foram avaliados os parâmetros morfológicos das mudas, suas relações e o índice de qualidade de Dickson. As mudas de fedegoso não apresentaram diferença significativa para nenhuma das características avaliadas no Argissolo Vermelho-Amarelo. Já no Latossolo Vermelho-Amarelo distrófico e no Latossolo Vermelho-Amarelo álico houve diferença significativa para todas as características avaliadas, exceto para a altura da parte aérea no primeiro e para o peso de matéria seca da parte aérea no segundo solo. As saturações por bases que forneceram as melhores mudas foram de 60% para Argissolo Vermelho-Amarelo, 70% para o Latossolo Vermelho-Amarelo distrófico e de 65% para Latossolo Vermelho-Amarelo álico.

White mold detection in common beans through leaf reflectance spectroscopy

ABSTRACT This study aimed to identify wavelengths based on leaf reflectance (400-1050 nm) to estimate white mold severity in common beans at different seasons. Two experiments were carried out, one during fall and another in winter. Partial Least Squares (PLS) regression was used to establish a set of wavelengths that better estimates the disease severity at a specific date. Therefore, observations were previously divided in two sub-groups. The first one (calibration) was used for model building and the second subgroup for model testing. Error measurements and correlation between measured and predicted values of disease severity index were employed to provide the best wavelengths in both seasons. The average indexes of each experiment were of 5.8% and 7.4%, which is considered low. Spectral bands ranged between blue and green, green and red, and red and infrared, being most sensitive for disease estimation. Beyond the transition ranges, other spectral regions also presented wavelengths with potential to determine the disease severity, such as red, green, and near infrared.

Evaluation of common mental disorders in women with polycystic ovary syndrome and its relationship with body mass index

PURPOSE: To evaluate the prevalence of common mental disorders in women diagnosed with polycystic ovary syndrome as compared with paired controls without this syndrome. METHODS: Cross-sectional study with a Control Group examining women between the ages of 18 and 30 who did not use antidepressants and who sought the Gynecology Service of the researched sites. For every woman diagnosed with the polycystic ovary syndrome, another with the same age, educational status and presence or absence of sexual partners was sought without this diagnosis. In total, 166 patients agreed to participate, consisting of 95 diagnosed with polycystic ovary syndrome and 71 in the Control Group. The diagnosis of polycystic ovary syndrome was made by the presence of two from three criteria: oligomenorrhea or amenorrhea, clinical or biochemical hyperandrogenism and polycystic ovaries on transvaginal ultrasound, following exclusion of patients with Cushing's syndrome, congenital adrenal hyperplasia, and androgen-secreting tumors. Weight and height were measured to calculate the body mass index. The Self-Reporting Questionnaire, which evaluated 20 items, was used as an indicator of common mental disorders. A χ² analysis stratified by the category of body mass index was used to compare the prevalence of common mental disorders, between the groups of women with and without the polycystic ovary syndrome. RESULTS: There were no significant differences in age, education, presence of sexual partners, ethnicity, socioeconomic status, use of psychiatric medication, and search for consultation in mental health between the studied groups. The prevalence of obese women with indications of common mental disorders was significantly higher in women with polycystic ovary syndrome than in the Control Group. In the group with healthy body mass index, the incidence of common mental disorders was statistically significant different between women with polycystic ovary syndrome and normal controls (p=0.008). CONCLUSIONS: Women with diagnosis of this disease have an almost three-fold increased likelihood of common mental disorders as compared with those without polycystic ovary syndrome. Although obesity is often observed in polycystic ovary syndrome, even women with a healthy body mass index have an increased risk of psychiatric comorbidity.
