Contrasting Responses to Ethenylbenzene (Styrene) and 2-Ethyl-1-hexanol Suggest their Role as Chemical Cues in Host Selection by the Seed Beetle Zabrotes subfasciatus (Coleoptera: Chrysomelidae: Bruchinae).

Seed beetles spend most of their lives within the seeds of host plants belonging to the Fabaceae family. Evidence suggests the cues that mediate pre-oviposition behaviour in Zabrotes subfasciatus (Boheman) are volatile organic compounds (VOCs) emitted by the seeds and suggests differential abilities in environment sensing between sexes. Here, we tested whether VOCs from different legume species trigger different levels of attraction, whether females and males differ in their ability to respond to VOCs, and whether the seeds promoting different behaviours feature singular VOCs.

Allelochemical Activity of Eugenol-Derived Coumarins on L.

Coumarins are widely distributed substances in plant species that promote phytotoxic effects, allowing them to be exploited as herbicides less harmful to the environment, since many invasive species have demonstrated resistance to commercially available products. The derived coumarins used in this study had not been tested in plant models and their effect on plants was unknown. The objective of this study was to evaluate the phytotoxic action of these coumarins in bioassays with L.

Statistical methods for identification of golden ratio.

Several biological systems such as the biomechanics of human heart, locomotion, and phyllotaxis of plants present a harmonic behavior because their fractal structure are associated to the golden ratio. The golden ratio (Φ = 1.618033988749…), also known as Phi, golden mean, golden section or divine proportion, is an irrational constant found in various forms in nature and recently has been used in many health areas.

Photodynamic therapy for Schistosoma mansoni: Promising outcomes.

The purpose of this study was to assess, for the very first time, the effects of photodynamic therapy (PDT) on Schistosoma mansoni in vitro by measuring reactive oxygen species (ROS) generation throughout the treatment, as well as the behavior of the parasites (mating, motility and contraction/shortening), and damage to their tegument and excretory systems. The parasites were divided into 4 groups: control, photosensitizer, laser and PDT. Light irradiation was delivered with an InGaAlP low-level laser device operating at 660nm, with 40mW and 100J/cm.

Analysis of the Environmental Management System based on ISO 14001 on the American continent.

The American continent is in broad economic and industrial development. Consequently, a more detailed discussion of the impacts generated by such development is needed. Moreover, there is an increase in the number of ISO 14001 certificates issued to this continent.

[Evaluation of depressive symptoms and resilience in patients on pharmacotherapeutic follow-up].

This study aimed to carry out the pharmacotherapeutic follow-up of patients with depression and to assess its impact on the resilience of the patients. Patients were followed-up for 8 months. The pharmacist evaluated depressive symptoms, resilience, and the need for pharmaceutical intervention.

Anthropogenic Matrices Favor Homogenization of Tree Reproductive Functions in a Highly Fragmented Landscape.

Species homogenization or floristic differentiation are two possible consequences of the fragmentation process in plant communities. Despite the few studies, it seems clear that fragments with low forest cover inserted in anthropogenic matrices are more likely to experience floristic homogenization. However, the homogenization process has two other components, genetic and functional, which have not been investigated.

Oral Paracoccidioidomycosis Granulomas are Predominantly Populated by CD163+ Multinucleated Giant Cells.

Multinucleated giant cells (MGC) are considered to be a hallmark of granulomatous inflammation; thus, they may play an essential role in the host response against pathogens, particularly Paracoccidioides brasiliensis. This study characterizes the MGC found in oral paracoccidioidomycosis and assesses the correlation of MGC with the amount of fungi within oral tissues. Twenty-six cases were included.

Ecotoxicity of raw and treated effluents generated by a veterinary pharmaceutical company: a comparison of the sensitivities of different standardized tests.

Pharmaceutical effluents have recently been recognized as an important contamination source to aquatic environments and the toxicity related to the presence of antibiotics in effluents has attracted great attention. Conventionally, these effluents have been treated using physico-chemical and aerobic biological processes, usually with low rates of pharmaceuticals removal. Due to the complexity of effluents, it is impossible to determine all pharmaceuticals and their degradation products using analytical methods.

Contamination from an affluent of Furnas reservoir by trace metals.

This study aims to determine concentrations and characterize trace metals distribution in an affluent of Furnas reservoir, Alfenas-MG. Water and sediment samples were taken monthly, 2010/10-2011/07 in five sites of Córrego do Pântano for subsequent determination of Pb, Cd and Zn levels by chemical analysis. The stream studied is in disagreement with Brazilian legislation for Class II water bodies (CONAMA 357).

Correlation between inflammatory infiltrate and epithelial lining in 214 cases of periapical cysts.

The aim of this study was to evaluate the prevalence of periapical cysts, identify their clinical and microscopic features and correlate their microscopic features with the inflammatory infiltrate present in the lesion site. A total of 214 cases were collected over a 10-year period. Clinical data, including gender, age, race, symptoms and location of the lesion, were recorded.

Assessment of the effectiveness of pharmacotherapy follow-up in patients treated for depression.

Background: Several studies have established the effectiveness of pharmaceutical care (PC) in patients with heart failure, diabetes, hypertension, and dyslipidemia. However, there are few studies using standardized methods, e.g.

Efficacy of different instruments for the identification of the nursing diagnosis spiritual distress.

The study aims to identify the nursing diagnosis Spiritual distress in 120 patients with Chronic Renal Insufficiency, using different instruments, and to evaluate the effectiveness of these instruments in support of this identification. Data were collected separately by two nurses using a questionnaire containing sociodemographic information and the defining characteristics of Spiritual distress, as well as direct questioning to the patient regarding the presence of the diagnosis and the instruments: the Spirituality Rating Scale; Pinto and Pais-Ribeiro's Spirituality Scale; and the Spiritual Well-being Scale. The study found that 25.

Leishmanicidal activity of benzophenones and extracts from Garcinia brasiliensis Mart. fruits.

Infections by protozoans of the genus Leishmania are the major worldwide health problem, with high endemicity in developing countries. The drugs of choice for the treatment of leishmaniasis are the pentavalent antimonials, which exert renal and cardiac toxicity. Thus, there is a strong need for safer and more effective treatments against leishmaniasis.
