Artisanal fish fences pose broad and unexpected threats to the tropical coastal seascape

Nature Communications, 2019
Artisanal fish fences are used for fishing along many tropical coastlines. Here, Exton et al. examine the impact footprint of artisanal fish fences, showing that they are highly non-selective, cause direct harm across the tropical seascape, disrupt ...

Temperate functional niche availability not resident-invader competition shapes tropicalisation in reef fishes

Nature Communications, 2023
Temperate reefs are at the forefront of warming-induced community alterations resulting from poleward range shifts. This tropicalisation is exemplified and amplified by tropical species’ invasions of temperate herbivory functions.

Temporal Changes in a Tropical Nekton Assemblage and Performance of a Prawn Selective Gear [PDF]

, 1995
The temporal variation of components of a moderately diverse (H=1.46) tropical estuarine fish assemblage (long. 146°30'E, lat. 8°45'S) was directed by salinities that had been determined by local oceanographic and probably topographic conditions.

Testicular mRNA‐LNP Delivery: A Novel Therapy for Genetic Spermatogenic Disorders

Advanced Science, EarlyView.
In the current study, we developed a novel therapy for genetic spermatogenic disorders. It was revealed that in vivo delivery of mRNA LNP3 could restore spermatogenesis in Msh5D486Y/D486Y and Maps KO mouse models with meiotic arrest. Notably, the offspring without genomic integration was born using ICSI derived from the rescue of Msh5D486Y/D486Y mouse ...

Cinnamic‐Hydroxamic‐Acid Derivatives Exhibit Antibiotic, Anti‐Biofilm, and Supercoiling Relaxation Properties by Targeting Bacterial Nucleoid‐Associated Protein HU

Advanced Science, EarlyView.
Cinnamic‐hydroxamic‐acid derivatives (CHADs) are identified as novel inhibitors of the bacterial nucleoid‐associated protein HU, exhibiting potent antibacterial, anti‐biofilm (both inhibition and eradication), and DNA relaxation (anti‐supercoiling) activities. Moreover, CHADs demonstrate strong synergistic effects with multiple antibiotics.

Changes in Oxidation and Reduction Potential (Eh) and Ph of Tropical Fish During Storage [PDF]

, 2011
Four tropical fish species, Thunnus albacares (Yellowfin tuna), Ephinephelus striatus (Nassau Grouper), Cyprinus carpio (Carp), and Osphronemus gourami (Gouramy), were assayed for oxidation reduction potental (Eh) and pH in different temperature,i.e ...

The Osteoblastic Microenvironment Determines the Fate of Breast Cancer Cells Disseminated in the Bone Marrow

Advanced Science, EarlyView.
This study revealed how the osteoblastic microenvironment determines the fate of cancer cells disseminated in bone, with a focus on whether they colonize, reside in quiescence, or reactivate from dormancy. Targeting integrin signaling may offer promising strategies for preventing quiescent cancer cells reactivation and bone colonization.
