Irradiação e atmosfera modificada passiva na qualidade pós-colheita de goiabas 'Pedro Sato'

The aim of this study was to evaluate the effect of gamma radiation associated with modified atmosphere on postharvest quality of guavas ‘Pedro Sato’. It was used guavas from the region of Vista Alegre do Alto/São Paulo/Brazil. After harvest, the fruits were immediately transported to the Fruit and Vegetables Laboratory from the Agroindustrial Management and Technology Department, Agronomic Sciences College - UNESP - Botucatu / SP, where they were kept at 10 ° C and 90-95% RH in cold storage, for 28 days. It was used the randomized design, with factorial scheme 5 x 5, three repetitions. The first factor consisted of the following effects: control 1 (without package or irradiation), control 2 (polystyrene package/PS + package low density polyethylene/LDPE and without irradiation), treatment 1 (PS + LDPE and 0.2 kGy ), treatment 2 (PS + LDPE and 0.6 kGy) and treatment 3 (PS + LDPE and 1.0 kGy). The second factor consisted of the evaluation periods: 0, 7, 14, 21 and 28 days. The analyses were: firmness, soluble solids (SS), titratable acidity (TA), maturity index, pH, respiration rate. Concluded that high doses of irradiation promoted a negative effect on physical-chemical characteristics of guava ‘Pedro Sato’, verifying that only the lowest dose associated with modified atmosphere provided fruits with higher quality and acceptability, due to higher maturation rate and soluble solids obtained. Regarding the days of analysis, there were no positive effect of the treatments during storage, where only the early days promoted better values for the variables studied.

Conservação de goiabas ‘Pedro Sato’ minimamente processadas e irradiadas

The aim of this study was to evaluate the effect of gamma irradiation associated with modified atmosphere in cold storage of guava ‘Pedro Sato’ minimally processed, checking their physical-chemical characteristics. Were used guavas from the region of Vista Alegre do Alto/São Paulo/Brazil. After harvest, fruits were immediately transported to the Fruit and Vegetables Laboratory from the Agroindustrial Management and Technology Department, Agronomic Sciences College - UNESP - Botucatu / SP, where they were kept at 10 ° C and 90-95% RH in cold storage, for 12 days. In the laboratory, fruits were selected by size and lack of defects in order to standardize the lot and then were cut into slices 0.5 cm thick. We used the completely randomized design, with factorial design 5 x 5, with three replications. The first factor consisted of the following effects: control 1 (without package or irradiation), control 2 (polystyrene package/PS + package low density polyethylene/LDPE and without irradiation), treatment 1 (PS + LDPE and 0.2 kGy ), treatment 2 (PS + LDPE and 0.6 kGy) and treatment 3 (PS + LDPE and 1.0 kGy). The second factor consisted of the evaluation periods: 0, 3, 6, 9 and 12 days. The analyses were: firmness, soluble solids (SS), titratable acidity (TA), maturity index, pH, breathing behavior. In the end of this work it was concluded that the lower dose of radiation associated with modified atmosphere promoted positive effect on physical-chemical characteristics of guava ‘Pedro Sato’, providing fruits with higher quality and durability, due to higher maintenance of pulp firmness, the highest pH and soluble solids obtained. Regarding the storage days, there were no beneficial effect of the treatments during storage, mainly due to the sensitivity of fruits submitted to gamma irradiation, where only the early days provided better values for the variables.

NONSPECIFIC INFECTIOUS DISEASES IN PREHISTORIC SAN PEDRO DE ATACAMA, NORTHERN CHILE

The region of San Pedro de Atacama, Northern Chile, has undergone several cultural and social changes after humans settled in Atacama Desert around 500 BC. The Atacameno people experienced the highest degree of social and cultural changes between 400 and 900 AD when they were assimilated into the Tiwanaku trade and political web that influenced most of the Central-Southern Andes. Under the influence of Tiwanaku, San Pedro de Atacama experienced its greatest economic development. Prior analyses of local human skeletal remains have shown a significant increase in the stature of the local population during the same period. In this paper, we investigate the impact of the Tiwanaku influence on the local epidemiological profile using the incidence of periostitis and osteomyelitis as indicators of biological stress. Surprisingly, the best epidemiological condition occurred during the final phase of influence of Tiwanaku (910-960 AD), and not during the apex influence (480-920 AD), as expected by the archaeological context. We suggest that population growth and aggregation may have counteracted the benefits of improved nutrition during the peak Tiwanaku influence. A severe drought occurred between 1,100 and 1,400 AD in Northern Chile. This could also explain the marked increase of bone infections in the post-Tiwanaku period (920-1,240 AD).

A New Species of Fissurella from Sao Pedro e Sao Paulo Archipelago, Brazil (Vetigastropoda, Fissurellidae)

Fissurella mesoatlantica n. sp. is endemic to the Saint Peter and Saint Paul Archipelago, Brazil, located approximately in the middle Atlantic (00 degrees 55N. 29 degrees 20W). The species is very similar to F. clenchi from the mainland Brazilian coast, differing in having a taller. more richly sculptured shell and by anatomical details. such its the papillae of mantle border and epipodial tentacles.

Trends in aortic aneurysm- and dissection-related mortality in the state of Sao Paulo, Brazil, 1985-2009: multiple-cause-of-death analysis

Background: Aortic aneurysm and dissection are important causes of death in older people. Ruptured aneurysms show catastrophic fatality rates reaching near 80%. Few population-based mortality studies have been published in the world and none in Brazil. The objective of the present study was to use multiple-cause-of-death methodology in the analysis of mortality trends related to aortic aneurysm and dissection in the state of Sao Paulo, between 1985 and 2009. Methods: We analyzed mortality data from the Sao Paulo State Data Analysis System, selecting all death certificates on which aortic aneurysm and dissection were listed as a cause-of-death. The variables sex, age, season of the year, and underlying, associated or total mentions of causes of death were studied using standardized mortality rates, proportions and historical trends. Statistical analyses were performed by chi-square goodness-of-fit and H Kruskal-Wallis tests, and variance analysis. The joinpoint regression model was used to evaluate changes in age-standardized rates trends. A p value less than 0.05 was regarded as significant. Results: Over a 25-year period, there were 42,615 deaths related to aortic aneurysm and dissection, of which 36,088 (84.7%) were identified as underlying cause and 6,527 (15.3%) as an associated cause-of-death. Dissection and ruptured aneurysms were considered as an underlying cause of death in 93% of the deaths. For the entire period, a significant increased trend of age-standardized death rates was observed in men and women, while certain non-significant decreases occurred from 1996/2004 until 2009. Abdominal aortic aneurysms and aortic dissections prevailed among men and aortic dissections and aortic aneurysms of unspecified site among women. In 1985 and 2009 death rates ratios of men to women were respectively 2.86 and 2.19, corresponding to a difference decrease between rates of 23.4%. For aortic dissection, ruptured and non-ruptured aneurysms, the overall mean ages at death were, respectively, 63.2, 68.4 and 71.6 years; while, as the underlying cause, the main associated causes of death were as follows: hemorrhages (in 43.8%/40.5%/13.9%); hypertensive diseases (in 49.2%/22.43%/24.5%) and atherosclerosis (in 14.8%/25.5%/15.3%); and, as associated causes, their principal overall underlying causes of death were diseases of the circulatory (55.7%), and respiratory (13.8%) systems and neoplasms (7.8%). A significant seasonal variation, with highest frequency in winter, occurred in deaths identified as underlying cause for aortic dissection, ruptured and non-ruptured aneurysms. Conclusions: This study introduces the methodology of multiple-causes-of-death to enhance epidemiologic knowledge of aortic aneurysm and dissection in Sao Paulo, Brazil. The results presented confer light to the importance of mortality statistics and the need for epidemiologic studies to understand unique trends in our own population.

In the first moment of concentration, key concepts and deliberative bioethics contents were developed. The second involved deliberation sessions on moral conflicts, which were selected and prepared during the dispersion interval. Participants evaluated the deliberation as an appropriate instrument to deal with the ethical issues they are faced with. Problem-based learning was an effective educational strategy for continuing education in deliberative bioethics.

Use of ground-penetrating radar to map subsurface features at the Lapa do Santo archaeological site (Brazil)

In this article we present some results of ground-penetrating radar (GPR) studies carried out at the Lapa do Santo archaeological site. This cave is within the Lagoa Santa karstic region, Minas Gerais State, Brazil. Results from 44 GPR profiles obtained with 400 MHz shielded antennas indicated anomalous hyperbolic reflections and areas with high sub-horizontal reflection amplitude suggesting archaeological and geological potential targets, respectively. These results were encouraging and were used to guide excavations at this site. Excavation of test units (metre by metre) allowed identifying an anthropogenic feature, e.g., a fire hearth structure and natural features, such as a stalagmite and top of bedrock. Results also indicated the importance of the GPR survey as a tool for orienting archaeological researches, increasing the probability of finding archaeological interest targets in an excavation program in an area of environmental protection.

Two new species of Tornidae (Caenogastropoda, Rissooidea) from Espirito Santo, Brazil

Two new species of shallow water Tornidae are found in Espirito Santo state, Brazil, formally described herein. They belong to a complex group of tiny gastropods, in such the taxonomy is very confused. Cyclostremiscus mohicanus sp. n. is characterized by three well-developed spiral, equidistant carinas, working as base of three series of tall, aligned periostracal rods. Episcinia itanhuna sp. n. has as single sculpture a series of pustules in periphery, but the periostracum bears three series of peripheral fringes with irregular rods. The new species are compared with the allies, showing a close relation with Caribbean fauna, but possessing worthy differences. These similarities have raised misidentifications.
