Abstract: The use of the extraordinary hydroelectric potential of the Amazon Basin originated an increase in the offer of renewable energy in Brazil, which, in its turn, leads to conflicts and a lack of consensus among different players owing to the potential negative impacts related to the construction and operation of large hydroelectric power plants in relatively well preserved areas. In this context, environmental licensing is one of the national environmental policy’s main instruments for making decisions regarding the use of the hydroelectric potential, especially the rivers of the Amazon Basin. Nevertheless, this significant instrument has its limitations and requires adjustments in order to better aid the decision making process regarding the use of water resources and land with the goal of increasing the offer of electric energy.

Abstract: The major objective of this work was to identify and quantify forest fragments suitable to be used as private protected land in rural properties located in the S o Bartolomeu creek watershed, State of Minas Gerais, Brazil. The methodological procedures included: mapping of 78 forest fragments through the visual interpretation of an Ikonos II satellite image; delineation of Permanent Preservation Areas (PPAs) from a hydrographically conditioned digital elevation model and mapping of 292 rural properties through interviews with owners, with the aid of a printed Ikonos II image. The generated maps were overlapped (crossed), allowing the identification of forest fragments that could be used as private protected land in rural property. The result indicated that, from the total of properties evaluated, only 41 (14.04%) have more than 20% of forest cover, and therefore, are in condition to attend the environmental law for private protected land.

Abstract: Objective. To evaluate the prevalence of HSV-1 and HSV-2 in pregnant and nonpregnant women, testing the correlation between DNA of the viruses with colposcopic and/or cytological changes, and evaluate association with sociodemographic characteristics and sexual activity. Methods. Included in this study were 106 pregnant and 130 nonpregnant women treated at primary health care units of Natal, Brazil, in the period 2010-2011. The patients were examined by colposcopy, and two cervical specimens were collected: one for cytology examination and another for analysis by PCR for detection of HSV-1 and HSV-2. Results. HSV-1 alone was detected in 16.0% of pregnant and 30.0% of nonpregnant women. For HSV-2, these rates were 12.3% and 15.5%, respectively. HSV-2 had a higher correlation with cytology and/or colposcopy changes than HSV-1 did. Genital HSV-1 infection was not associated with any of the variables tested, whereas HSV-2 infection was associated with ethnicity, marital status, and number of sexual partners. Conclusions. The prevalence of HSV-1 was higher than that observed for HSV-2 in both pregnant and nonpregnant women. The genital infection by HSV-2 was higher in women with changed colposcopy and/or cytology, and it was associated with ethnicity, marital status, and number of sexual partners. 1. Introduction Herpes simplex virus (HSV) is a neurotropic virus that has a large linear, double-stranded DNA genome protected by a capsid with icosahedral symmetry surrounded by an envelope consisting of a lipid bilayer with embedded glycoproteins, having yet a proteinaceous region between the capsid and envelope called tegument [1]. The HSV belongs to the family of Herpesviridae, subfamily Alphaherpesvirinae, and genus Simplex virus [2, 3]. It is a virus that has a very complex life cycle and stands out as one of the most common pathogens in the etiology of sexually transmitted diseases worldwide [4]. HSV infects the mucosa of the mouth, eyes, and the human anogenital tract. After primary infection, the virus replicates productively within mucosal epithelial cells and enters sensory neurons via nerve termini. The virus is then transported to neuronal cell bodies where latency is established. The virus can remain in this latent state indefinitely but can be reactivated at any time during the lifetime of the host [4, 5]. During latent infection, no infectious virus is produced from infected cells, symptoms are absent in the host, and the transmission does not occur. However, reactivation can occur only in some cells, in the absence of symptoms, enabling the

Abstract: Objective. The purpose of this study was to assess the knowledge level about HPV and screening of cervical cancer in women from the metropolitan region of Natal, Brazil. Materials and Methods. A descriptive cross-sectional study involving sexually active women was conducted. The participants were submitted to a face-to-face interview, using a structured questionnaire that permitted the quantification of data and opinions of the respondents. Results. Most participants (70.9%) had poor knowledge about HPV and also the Pap test (53.0%). The high level of knowledge about HPV was associated with age, education, marital status, household income, and pregnancy, while the high level of knowledge about the Pap test proved to be associated only with education and household income. Conclusion. The results highlight the need for performing educational campaigns emphasizing the role of HPV in the etiology of cervical lesions of different degrees, including cervical cancer, as well as the importance of having a Pap test regularly to prevent these diseases. 1. Introduction Cervical cancer is the third most common cancer affecting women, after nonmelanoma skin cancer and breast cancer, and is the third leading cause of death by cancer among women worldwide, with higher incidence in developing countries [1, 2]. It is estimated that about 500,000 new cases are reported every year, with approximately 230,000 deaths worldwide. In Brazil, the crude incidence rates per 100,000 women, estimated for the year 2012, were 17 for the country and 14 for the Rio Grande do Norte State. The incidence of the disease starts from the age of 20 and the risk gradually increases with age, reaching its peak generally at age 50 to 60 [3]. The natural history of cervical cancer reveals that, despite its high incidence, this malignant neoplasm stands out among those with the greatest potential for prevention and cure in view of their infectious nature [4]. Cervical cytology is one of the most efficient methods for the screening of cervical cancer and is the most commonly used method worldwide [5]. Despite its benefits, many women in developing countries have never been screened or are not screened at regular intervals, so that this screening program does not have the desired impact on women’s health [6]. Reasons for the lack of effectiveness of these screening programs in developing countries include low screening coverage and participation rates among women, lack of quality control, poor ability of the health care system to offer proper followup and access to colposcopy, and inappropriate

Abstract: the objective of this work was to characterize iron oxides from b-horizons of three soil profiles developing on gneiss of the ba??o complex geodomain in the quadrilátero ferrífero, minas gerais, brazil. samples were collected from the uppest, middle and lowest segments along the slope. the earth fine fractions (mean diameter, f = 2 mm) were separated for all samples. the chemical composition of the major elements was determined with the x-ray fluorescence technique; the mineralogical analysis was performed with powder x-ray diffractomer and m?ssbauer spectroscopy. all samples have similar mineralogical composition, with a general occurrence corresponding to the sequence quartz >> gibbsite > kaolinite > goethite. from the 4.2 k-m?ssbauer results, the coexistence of goethite (major) and hematite is confirmed. the isomorphic aluminum contents, as they were deduced from the hyperfine fields, lead to the following chemical formulas for goethites: afe0.79al0.21ooh (upslope), afe0.75al0.25ooh (midslope) and afe0.78al0.22ooh (downslope). the iron oxides transformation dynamics in b horizons along the slope is a useful indicator of the paleo-climatic oscillations in this area: aluminous goethite is an indicator of humid paleo-environments, whereas aluminous-poorer goethite reveals drier pedogenic conditions.

Abstract: objectives: critically ill cancer patients are at increased risk for acute kidney injury, but studies on these patients are scarce and were all single centered conducted in specialized intensive care units. the objective was to evaluate the characteristics and outcomes in a prospective cohort of cancer patients admitted to several intensive care units with acute kidney injury. methods: prospective multicenter cohort study conducted in intensive care units from 28 hospitals in brazil over a two-month period. univariate and multivariate logistic regression were used to identify factors associated with hospital mortality. results: out of all 717 intensive care unit admissions, 87 (12%) had acute kidney injury and 36% of them received renal replacement therapy. kidney injury developed more frequently in patients with hematological malignancies than in patients with solid tumors (26% vs. 11%, p=0.003). ischemia/shock (76%) and sepsis (67%) were the main contributing factor for and kidney injury was multifactorial in 79% of the patients. hospital mortality was 71%. general and renal-specific severity-of-illness scores were inaccurate in predicting outcomes for these patients. in a multivariate analysis, length of hospital stay prior to intensive care unit, acute organ dysfunctions, need for mechanical ventilation and a poor performance status were associated with increased mortality. moreover, cancer-related characteristics were not associated with outcomes. conclusions: the present study demonstrates that intensive care units admission and advanced life-support should be considered in selected critically ill cancer patients with kidney injury.
