Assisted natural regeneration: a tool for degraded tropical forests [PDF]

, 2011
A major part of anthropic impacts on natural tropical forests in central Africa is related to unmanaged shifting agriculture and fuelwood extraction by local communities, mainly along access tracks (roads, rivers,...)and at the edge of forests.

Climate Change Threatens Micronutrient Density of European Winter Wheat

Advanced Science, EarlyView.
Micronutrients are vital for human health. Wheat is a major staple crop and a significant source of minerals and B‐vitamins. The impact of climate change on their content remains largely unknown. We evaluated micronutrient levels in European winter wheat grown under historical and projected climate conditions. Our findings indicate that future climates

Unraveling the Molecular Mechanisms Underlying Spontaneous Multipolar Mitosis Through CIN‐seq

Advanced Science, EarlyView.
Multipolar mitosis, a hallmark of chromosomal instability (CIN), drives tumor heterogeneity but is challenging to study in live cells. Using CIN‐seq, a single‐cell multiomics method, we profiled rare CIN events and identified mechanisms associated with viable multipolar mitosis, including PTEN attenuation, Rho GTPase‐driven cytokinesis failure, and ...

SEED REMOVAL IN AN ATLANTIC FOREST FRAGMENT AND A RESTORATION SITE IN SOUTHERN BRAZIL

Revista do Instituto Florestal, 2012
In ecological restoration, the loss of seeds can be a major constraint to the establishment of seedlings and thus for the continuity of the forest succession process.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...

Improvement of seed germination of Fagus orientalis Lipsky [PDF]

, 2003
This thesis was seeking two main approaches for improvement of seed germination of oriental beech, a timber producing species in Hyrcanian forests in northern Iran. Germination behavior of beechnuts was enhanced either by decreasing the dormancy breakage

A seed-diffusion model for tropical tree diversity patterns

, 2012
Diversity patterns of tree species in a tropical forest community are approached by a simple lattice model and investigated by Monte Carlo simulations using a backtracking method.

Endogenous “Time Bomb” – Mislocalized Phospholipase A2 as a Critical Mediator of Ultra‐Rapid Mortality in Sepsis and Acute Lung Injury

Advanced Science, EarlyView.
Phospholipase A2 (PLA2), a dormant enzyme, becomes lethal when activated—collapsing lungs in minutes. Our dual therapy (DOPS + varespladib) boosts survival from 0% to >90% in sepsis/ALI. A breakthrough for acute lung injury treatment. ABSTRACT This study reveals that phospholipase A2 (PLA2), normally stable and nontoxic, can be activated specifically ...
