DOTA‐grafted Cationic Polymers Behaving as Powerful Macromolecular Resistance‐reversal Agents (MRRAs) Combating Against New Delhi Metallo‐β‐lactamase (NDM)‐producing Bacteria

open access: yesAdvanced Science, EarlyView.
Two macromolecular resistance‐reversal agents (MRRAs)—linear (MRRAL) and nanostructured (MRRAN) polymers were fabricated by integrating DOTA motifs into tunable polycationic scaffolds. MRRAs exhibit superior antibacterial potency once combined with meropenem (MEM) through (i) bacterial membrane disruption via localized cationic charge and ...

Field notes on findings of threatened amphibian species in the central mountain range of western Panama [PDF]

open access: yes, 2012
During field work along a transect in the Cordillera Central of western Panama between 2008 and 2010, we detected several populations of amphibian species which are considered as “Endangered” or “Critically Endangered” by the IUCN.

Nanotherapeutic Macrophage‐Neuro Reprogramming Through Immunometabolic Crosstalk Mitigates Sepsis‐Induced Lung Injury and Neurologic Damage

open access: yesAdvanced Science, EarlyView.
SJNPs co‐deliver JHU083 and spermine to reprogram macrophage–neuron immunometabolic crosstalk in sepsis. By suppressing pro‐inflammatory M1 polarization and promoting NGF‐mediated neurotrophic signaling, SJNPs preserve pulmonary neuronal integrity, alleviate lung injury, and improve survival in murine sepsis models.

Sonneratia ovata Backer (Lythraceae): status and distribution of a Near Threatened mangrove species in tsunami impacted mangrove habitats of Nicobar Islands, India

open access: yesJournal of Threatened Taxa, 2012
The world’s most productive ecosystem, the mangrove forest, is under immense pressure due to natural and human induced disturbances. The Indian Ocean tsunami on 26 December 2004 had an adverse effect on these habitats by breaking and uprooting the mangrove trees.

Neutrophil‐Mimetic Nanoscavengers Target the Inflammatory Microenvironment to Eliminate NETs/ROS and Immunomodulate cGAS‐STING Signaling in Septic AKI

open access: yesAdvanced Science, EarlyView.
Sepsis‐associated acute kidney injury is driven by oxidative stress, NETs overproduction, and dysregulated innate immunity. Here, we develop neutrophil‐mimetic nanoscavengers that integrate ROS‐scavenging Mn3O4 nanozymes with DNase‐1‐mediated NETs degradation to suppress cGAS‐STING signaling, reprogram macrophage polarization, and effectively alleviate

The threatened status of restricted-range coral reef fish species [PDF]

open access: yes, 2000
Coral reefs are the most diverse ecosystem in the sea. Throughout the world they are being overfished, polluted and destroyed, placing biodiversity at risk.

Optimal Grazing Exclusion Duration to Enhance Soil Carbon Sequestration in Degraded Grasslands

open access: yesAdvanced Science, EarlyView.
Across China, grazing exclusion reaches the national mean soil organic carbon recovery benchmark sooner in high‐MAP regions (> 500 mm), but recovery is much slower where MAP < 300 mm. Scaling this strategy to 70% of China's degraded grasslands would sequester about 1.52 Pg of soil carbon over 10 years—roughly 17% of annual global fossil‐fuel emissions.
