Melatonin, a hormone known for its effects on free radical scavenging and antioxidant activity, can reduce lead toxicity in vivo and in vitro.We examined the effects of melatonin on lead bio-distribution. Rats were intraperitoneally injected with lead acetate (10, 15 or 20 mg/kg/day) with or without melatonin (10 mg/kg/day) daily for 10 days. In rats intoxicated with the highest lead doses, those treated with melatonin had lower lead levels in blood and higher levels in urine and feces than those ...

Age estimation is one of the main biological parameters to be determined for constructing an individual biological profile. In contexts where bones are poorly preserved, the use of teeth becomes relevant. Translucency of dentine has become relevant in recent decades, since the publication of the method proposed by Lamendin et al. (1992). In the local context, studies validating age-estimation methods from the permanent dentition are lacking. For this reason, it was decided to evaluate the performance ...

AbstractRecent research into settlement patterns in the Valle de la Plata SW Colombia, has provided information on the regional social context of the long-famous statues and tombs of the Alto Magdalena (the "San Agustín Culture"). The region witnessed the development, soon after the time of Christ, of a series of small-scale chiefdoms, each consisting of a few thousand people and centered on the elaborate burial place of its chiefs. These burial places themselves were not used residentially, but were ...

Lung-function decline is one of the possible mechanisms leading to Chronic Obstructive Pulmonary Disease (COPD).We analyzed data obtained from two population-based surveys of adults (n = 2026) conducted in the same individuals 5-9 years (y) after their baseline examination in three Latin-American cities. Post BronchoDilator (postBD) FEV1 decline in mL/y, as %predicted/y (%P/y) and % of baseline/y (%B/y) was calculated and the influence of age, gender, BMI, baseline lung function, BD response, exacerbations rate ...

This study describes the reproductive period, spawning type, the size at first gonadal maturation and the length-weight relationship of individuals sampled from landings of the artisanal and commercial fishing fleets in Rio Grande that operate along the coast of Rio Grande do Sul state, southern Brazil (~ 32ºS) to the Uruguayan border (~ 34ºS).

Although the Río de la Plata craton is exposed over a relatively large area in Uruguay, eastern Argentina, and southernmost Brazil, its geological evolution is poorly known because of great geological complexity and paucity of data. We report here U–Pb ages of detrital zircons from samples of five Neoproterozoic sandstone units deposited on the Río de la Plata Craton (RPC) in Uruguay and Argentina. The zircon ages provide definitive evidence of a great range of ages of rocks composing the craton— ...

The Río de la Plata Grasslands (RPG) are one of the largest areas of open ecosystems (grasslands, shrublands and savannas) in the world. Historically, these systems have experienced, and continue to experience, an enormous loss of natural habitats. Moreover, their importance has been largely invisible in comparison to forested systems. The remaining area of open ecosystems in the RPG region varies according to the source from 38 to 58% of the original area. Open Ecosystems (OE) are a special case of ...

This work concerned uncertainty analysis for constructing stage-discharge rating curves to estimate error or uncertainty regarding calculated discharges, considering different discharge measurement availability scenarios. A methodology was used for creating artificial samples of discharge measurements from real data observed in the field and the effect of variation on measurement quantity and distribution concerning instantaneous discharge uncertainty was then studied. The results indicated that ...

A total number of 4824 Mustelus schmitti was sampled. Females ranged from 25 to 93 cm in spring and from 28 to 90 cm in summer. Males ranged from 34 to 82 and from 28 to 77 cm, respectively. Length composition of the population showed significant differences between spring and summer being females larger than males. Total length distribution did not show significant differences between cruises. Males density varied significantly between cruises while for the females no significant variation was ...

Institutional repositories play a central role as preservation and dissemination hubs for academic institutions. They are useful to increase knowledge access, measure science production and to make public institutions transparent. Repositories must ensure a back-and-forth collaboration with many institution parties, by setting up transparent workflows and offering services to encourage its use. This article presents the case of Universidad Nacional de La Plata, where a combination of policies, workflows ...

Se analizan el documento crítico, el manifiesto disidente y la contestación de la dirigencia de la organización. A partir de estas intervenciones se interrogan las inquietudes que tuvieron los montoneros para finales de la década de 1970, con la Contraofensiva ...

The geochemistry of two metavolcano-sedimentary sequences deposited in the Piedra Alta Terrane is compared, and their geotectonic evolution is discussed. The Ojosmín Unit (OU) comprises MORB-like basic rocks at the base and a fine-grained siliciclastic sequence interpreted as marine turbidites towards the top. The succession was later obducted during the Orosirian. Whole-rock geochemistry of the metasedimentary rocks of the OU indicates the lack of source rock alteration during deposition (Chemical ...

The Río de la Plata estuary (RdlP) and adjacent continental shelf exhibit complex hydrological processes as a result of a highly variable fluvial discharge and associated terrigenous supply, which are primarily controlled by regional climatic forcing in interaction with the oceanographic system. Previous hydrological studies indicate that Little Ice Age and Medieval Climate Anomaly resulted in increased/decreased river runoff due to an enhanced/weakened precipitation regime. This study aims to analyze ...

The present study evaluated the efficacy of an Italian school-based intervention programme adapted in three Colombian sites (Medellín, Manizales, and Santa Marta) in promoting prosocial behaviour among adolescents. Using a pre-test-post-test design with a multi-informant approach, the present study assessed 451 students (Mage = 12.77, SD = 1.06) of the intervention group and 428 students (Mage = 12.64, SD = 1.01) by using self-report and peer rating measures of prosocial behaviour. After establishing the measurement ...
