Generalidades de la farmacovigilancia
A través de los últimos años, el uso de medicamentos se volvió algo cotidiano, por lo mismo se crearon diferentes programas, actividades y procesos, para mitigar aquellos sucesos que atentaban contra la calidad de vida de las personas.
Entender la importancia de realizar la una serie de mecanismos que lograran comprobar la efectividad y seguridad de los medicamentos, dio origen a la farmacovigilancia, la cual se encarga de detección, prevención y evaluación de los efectos adversos que se pueden presentar a lo largo del tratamiento farmacológico.Over the last few years, the use of medicines has become a daily occurrence, and different programs, activities and processes have been created to mitigate those events that threaten the quality of life of people.
Understanding the importance of carrying out a series of mechanisms to verify the effectiveness and safety of medicines, gave rise to pharmacovigilance, which is responsible for detection, prevention and evaluation of adverse effects that may occur during pharmacological treatment
Factors Determining Seagrass Blue Carbon Across Bioregions and Geomorphologies
Este artículo contiene 15 páginas, 6 figuras, 1 tabla.Seagrass meadows rank among the most significant organic carbon (Corg) sinks on earth.
We examined the variability in seagrass soil Corg stocks and composition across Australia and identified
the main drivers of variability, applying a spatially hierarchical approach that incorporates bioregions and
geomorphic settings. Top 30 cm soil Corg stocks were similar across bioregions and geomorphic settings
(min-max: 20–26 Mg Corg ha−1), but meadows formed by large species (i.e., Amphibolis spp. and Posidonia
spp.) showed higher stocks (24–29 Mg Corg ha−1) than those formed by smaller species (e.g., Halodule,
Halophila, Ruppia, Zostera, Cymodocea, and Syringodium; 12–21 Mg Corg ha−1). In temperate coastal
meadows dominated by large species, soil Corg stocks mainly derived from seagrass Corg (72 ± 2%), while
allochthonous Corg dominated soil Corg stocks in meadows formed by small species in temperate and
tropical estuarine meadows (64 ± 5%). In temperate coastal meadows, soil Corg stocks were enhanced by
low hydrodynamic exposure associated with high mud and seagrass Corg contents. In temperate estuarine
meadows, soil Corg stocks were enhanced by high contributions of seagrass Corg, low to moderate solar
radiation, and low human pressure. In tropical estuarine meadows formed by small species, large soil Corg
stocks were mainly associated with low hydrodynamic energy, low rainfall, and high solar radiation. These
results showcase that bioregion and geomorphic setting are not necessarily good predictors of soil Corg
stocks and that site-specific estimates based on local environmental factors are needed for Blue Carbon
projects and greenhouse gases accounting purposes.This study was delivered as part of the Pilot Projects program of the

Comparing tropical forest tree size distributions with the predictions of metabolic ecology and equilibrium models
Tropical forests vary substantially in the densities of trees of different sizes and thus in above-ground biomass and carbon stores. However, these tree size distributions show fundamental similarities suggestive of underlying general principles. The theory of metabolic ecology predicts that tree abundances will scale as the -2 power of diameter. Demographic equilibrium theory explains tree abundances in terms of the scaling of growth and mortality. We use demographic equilibrium theory to derive analytic predictions for tree size distributions corresponding to different growth and mortality functions. We test both sets of predictions using data from 14 large-scale tropical forest plots encompassing censuses of 473 ha and \u3e 2 million trees. The data are uniformly inconsistent with the predictions of metabolic ecology. In most forests, size distributions are much closer to the predictions of demographic equilibrium, and thus, intersite variation in size distributions is explained partly by intersite variation in growth and mortality. © 2006 Blackwell Publishing Ltd/CNRS
Australian vegetated coastal ecosystems as global hotspots for climate change mitigation
Policies aiming to preserve vegetated coastal ecosystems (VCE; tidal marshes, mangroves and seagrasses) to mitigate greenhouse gas emissions require national assessments of blue carbon resources. Here, we present organic carbon (C) storage in VCE across Australian climate regions and estimate potential annual CO2 emission benefits of VCE conservation and restoration. Australia contributes 5–11% of the C stored in VCE globally (70–185 Tg C in aboveground biomass, and 1,055–1,540 Tg C in the upper 1 m of soils). Potential CO2 emissions from current VCE losses are estimated at 2.1–3.1 Tg CO2-e yr-1, increasing annual CO2 emissions from land use change in Australia by 12–21%. This assessment, the most comprehensive for any nation to-date, demonstrates the potential of conservation and restoration of VCE to underpin national policy development for reducing greenhouse gas emissions

Biodiversity, Nature and Food Security: A Global Perspective
Biodiversity is the basis for agriculture and for a
sustainable future. More than 1.9 million living
species have been described; millions more have
gone extinct, including major branches of the tree
of life. The distribution of this biological diversity is
variable in space and time, although it is becoming
more homogeneous as a result of
globalisation. Only a few hundred species of
plants and animals have been domesticated over
the past 10 000 years, yet they are essential for
the livelihoods of people worldwide. New tools are
giving us insights into the origins of agriculture, as
well as opening new possibilities for using and
changing the genetic diversity of these crops and
races. This can have a major impact on the wellbeing
of present and future generations. Agriculture
is also having major impacts on natural
ecosystems. An estimated 25% of terrestrial
ecosystems have been transformed into production
systems, mostly in the past 50 years. Habitat
loss and fragmentation, pollution and invasions
are some of the impacts. Climate change is likely
to have additional impacts that will alter the distribution
and abundance of biodiversity, as well as
the interactions among species. It is time to bring
together knowledge from biodiversity science and
agriculture through a whole-system approach. A
better understanding of the diversity, distribution,
evolution and ecology of life is essential for a
sustainable future. It can also open new avenues
for agriculture and food security
