Abstract: nesting and use of pollen resources by tetrapedia diversipes klug (apidae) in atlantic forest areas (rio de janeiro, brazil) in different stages of regeneration. the nesting in trap-nests and use of pollen sources in larval food by tetrapedia diversipes klug, 1810 (apidae) was compared between regenerating areas of atlantic forest. the study was conducted between april 2008 and october 2009 at uni?o biological reserve, rio de janeiro, brazil. t. diversipes nested in 66 trap-nests and showed a peak of nesting during the months of highest rainfall. the most frequent pollen type in brood cells during the wet season was dalechampia sp. 1. during the dry season, the type ludwigia sp. was the most frequent, followed by dalechampia sp. 2. the high frequency of dalechampia and ludwigia species in the larval food, observed in both habitats and in the two seasons could be considered relevant for t. diversipes, suggesting highly selective diet based primarily on two plant species unrelated, but similar in size of pollen grains.
In the Shadow of the Serbian Paramilitary Units: Narrative Patterns about the Role of Paramilitary Units in Former Yugoslav Conflict  [PDF]
Maria Vivod
Advances in Anthropology (AA) , 2013, DOI: 10.4236/aa.2013.31004
Abstract:
This article1 offers several basic data about Serbian paramilitary units employed in the armed conflict of the 1990’s during the decomposition of the former Yugoslavia, with the goal to depict the transformation of the representation of the paramilitary unit members and their leaders essentially through Serbian media. Once, at the beginning of the conflicts, represented as the saviors, protectors of the Serbian nation, ever present as main figures of the public life of the 90s—they have fallen into oblivion after a decade. Their most notorious leaders are either dead or in prison. After the fall of the Milo?evi? regime (2000) their involvement in war crimes, looting and genocide reached Serbia. From being divinized gradually they become diabolized. The contemporary events and happenings in Serbia are explained in the light of the past of these paramilitary units.
The Future Human Lifespan: A Study on Italian Population  [PDF]
Maria Russolillo
Applied Mathematics (AM) , 2014, DOI: 10.4236/am.2014.511158
Abstract:

In the latter part of the 20th century, continued improvements in living standards, health behaviors, and medical care reduced mortality and produced amazing advances in life expectancy. These trends, followed by all industrial nations, decidedly affect the financial position of an insurance company, interested in the construction of updated life tables. The approach to this problem is faced in this paper by using the Lee-Carter methodology. In particular, in the present work, we are interested in modeling and forecasting mortality and life expectancy on a period basis through the use of a stochastic forecasting method which uses time-series models to make long-term forecasts.

Assessment of strategic management practice of malaria control in the dangme west district, GhanaArticle submitted to the west african college of nursing for the award of a fellow  [PDF]

Health (Health) , 2011, DOI: 10.4236/health.2011.36059
Abstract: Strategic management (SM) practice was as-sessed in all HCFs both in the public and private and some chemical shops within the Dangme West district using semi-structured question-naires. In-depth interviews were carried out with healthcare managers in their clinical setting. The study utilized both qualitative and quantitative methods in describing the SM practice. Healthcare managers were using all the elements of SM in the management of malaria but these were not holistically coordinated. Present were short ranged informal planning based on the objectives of NMCP and day-to-day operation of the HCFs especially with Ghana Health Service facilities. Due to homogenous nature of Dangme West district, management of culture wasn’t given much attention by healthcare managers though healthcare providers were acutely aware of its importance to quality service delivery. Competition was woefully absent in the healthcare environment. No formal structure has been created for the management of malaria control activities with the exception of the involvement of Community Based agents. The district was widely implementing all the strategies of the NMCP with favourable outcomes.
A Fatal Case of Treatment-Related Adverse Effects in Granulomatosis with Polyangiitis (Wegener’s Granulomatosis)  [PDF]
Marina Magrey, Maria Antonelli
Open Journal of Rheumatology and Autoimmune Diseases (OJRA) , 2011, DOI: 10.4236/ojra.2011.12002
Abstract: Well-studied therapies have proven to be effective in treating Granulomatosis with polyangiitis (formerly Wegener’s granulomatosis) (GPA). There has been considerable improvement in survival of patients with GPA but treatment related morbidity and mortality remains still high, particularly in patients with renal disease. We describe a case of 64-year old woman with recent onset GPA, who responds well to the initial cyclophosphamide based therapy but latter develops a fatal stroke. Infectious complications should be considered in patients with GPA who are on adequate immunosuppression but develop symptoms that may mimic a relapse. Aggressive diagnostic interventions should be undertaken to discriminate between an infection and a relapse of GPA.
Can Purified Omega-3 Polyunsaturated Fatty Acids Supplementation Act Blood Pressure Levels in Untreated Normal-High Blood Pressure Subjects with Hypertriglyceridemia?  [PDF]
Maria Leonarda De Rosa
Pharmacology & Pharmacy (PP) , 2012, DOI: 10.4236/pp.2012.32031
Abstract: Omega-3 (ω-3) polyunsaturated fatty acids (PUFAs) from fish and fish oils appear to protect against coronary heart disease: their dietary intake is in fact inversely associated with cardiovascular disease morbidity/mortality in population studies. Recent evidence suggests that at least a part of this protective effect is mediated by a relatively small but significant decrease in blood pressure (BP) level. In fact, omega-3 PUFAs exhibit wide-ranging biological actions that include regulating both vasomotor tone and renal sodium excretion, partly competing with omega-6 PUFAs for common metabolic enzymes and thereby decreasing the production of vasoconstrictor rather than vasodilator and anti-inflammatory eicosanoids. PUFAs also reduce angiotensin-converting enzyme (ACE) activity, angiotensin II formation. We retrospectively evaluated the long-term effect of a omega-3 PUFAs supplementation on the blood pressure level of 91 hypertriglyceridemic subjects with untreated normal-high blood pressure that were prescribed a 3 grams omega-3 PUFAs supplementation in order to improve their plasma lipid pattern. After 24 months of treatment, systolic blood pressure (SBP) meanly decreased by 2.6 +/- 2.5 mmHg (p = 0.001) and diastolic blood pressure (DBP) by 1.4 +/- 3.1 mmHg (p < 0.001), while basal heart rate decreased by 4.1 +/- 4.6 bpm (p < 0.001). Both SBP and DBP reduction were significantly related to the baseline SBP (p < 0.001) and DBP (p < 0.001), respectively. Diastolic blood pressure change was also inversely related to the patient’s age (p = 0.004). No significant difference was perceived in the metabolic syndrome subgroup. In our retrospective study, highly purified omega-3 PUFAs long-term supplementation is associated with a significant reduction in SBP, DBP, and basal heart rate in hypertriglyceridemic patients with normal-high blood pressure. The main determinants of the omega-3 PUFAs anti-hypertensive effect appear to be the basal blood pressure level and age. Future research will clarify if omega-3 PUFAs supplementation could improve the antihypertensive action of specific blood pressure lowering drug classes and of statins.

Presentation of a Rare Case of Bilateral Lumbar Synovial Cysts  [PDF]
Konstantinos Violaris, Maria Karakyriou
Open Journal of Modern Neurosurgery (OJMN) , 2012, DOI: 10.4236/ojmn.2012.22006
Abstract: Purpose: To report a quite rare case of bilateral symptomatic synovial cysts of the lumbar spine. Surgical resection is usually the cure for this condition. Methods: A 65 year old female patient came to our department, complaining for severe lumbar and sciatic pain. MRI and CT were used to diagnose bilateral synovial cysts. Because of the intensity of symptoms, she was subjected to surgery. Laminectomy and cyst resection were performed. Results: The patient showed complete resolution of pain after the resection of the cysts. Conclusion: Although rare, bilateral synovial cysts may be the cause of severe lumbar pain. In cases of failure of conservative treatment, surgical resection offers good results.
Benefits and Costs of the Informal Sector: The Case of Brick Kilns in Bangladesh  [PDF]
Lelia Croitoru, Maria Sarraf
Journal of Environmental Protection (JEP) , 2012, DOI: 10.4236/jep.2012.36058
Abstract: In developing countries, the informal sector—brick kilns, leather tanning, food processing factories—is often highly polluting, causing countless deaths and illnesses. This paper presents the case of brick kilns in Dhaka, one of the most polluted cities in Asia. Five months per year, brick kilns are the city’s main source of fine particulate pollution, accounting for 38 percent of total fine particulate mass. The paper values the impacts of existing and alternative brick kiln technologies in Dhaka city. Through a Cost-Benefit Analysis, it estimates the net returns for the entrepreneur, and the social costs, such as health impacts from air pollution and damages due to carbon emissions from kilns. It shows that cleaner technologies are more attractive than traditional technologies both from the private and social perspective, and provides concrete recommendations for a cleaner brick sector in Bangladesh.
Graphic Organizers as a Reading Strategy: Research Findings and Issues  [PDF]
Polyxeni Manoli, Maria Papadopoulou
Creative Education (CE) , 2012, DOI: 10.4236/ce.2012.33055
Abstract: The present article extends prior research on graphic organizers mainly used as a reading strategy. Graphic strategies, visual representation of information in a text, refer to different approaches to reading from the traditional, linear text representation. This study constitutes an attempt to shed light on the research evidence regarding the effectiveness of GOs on text learning and the various types of graphic organizers, which use different conventions to communicate information and are classified in various ways. As such, it highlights key concepts, the theoretical and historical foundations of graphic organizers, includes the major types of graphic organizers, summarizes research findings, recommends ways of integrating them in reading lessons, touches on the issue of strategy instruction and its effects on language learning and leaves room for further exploration.
