Effect of terahertz irradiation on DNA damage repair in living cells

FEBS Open Bio, EarlyView.
We investigated the effect of terahertz (THz) wave irradiation on DNA double‐strand break (DSB) repair in living cells. We found that THz irradiation enhanced DSB repair at specific frequencies, whereas heat treatment inhibited it, indicating that this effect is nonthermal and frequency‐specific.

From Fish Eggs to Fish Name: Caviar Species Discrimination by COIBar-RFLP, an Efficient Molecular Approach to Detect Fraud in the Caviar Trade

Molecules, 2019
The demand for caviar is growing as is its price on the market. Due to the decline of true caviar production from sturgeons, eggs from other fish species and other animals have been used as substitutes for caviar.

A 3D Human Neuron‐on‐Chip Platform to Monitor Neuronal Injury Responses

Advanced Healthcare Materials, EarlyView.
This study presents a novel 3D Neuron‐on‐Chip model that can maintain human PSC‐derived excitatory prefrontal cortex neurons in 3D hydrogels and can be used to monitor neuronal injury responses over time. Results show injury‐induced acute neuronal excitotoxicity, declining neuronal connectivity, and the activation of a neurodegenerative, SASP‐like ...

Collaborative Study of a Rapid Electrophoretic Method for Fish Species Identification. II. Authentic Flesh Standards

Journal of AOAC INTERNATIONAL, 1970
Abstract The cellulose acetate method of fish species identification was collaboratively studied a second time, using authentic flesh samples as standards. Eleven collaborators were asked to identify ten unknown fish samples from a set of nine standard flesh samples. The collaborators identified the unknown samples with 91% accuracy.

HOF‐Stabilized Apple EV Nanocargo in an NIR‐Responsive Hydrogel Enables On‐Demand Therapeutic Modulation for Transdermal Deep‐Joint Osteoarthritis Therapy

Advanced Healthcare Materials, EarlyView.
An NIR‐responsive transdermal hydrogel integrating apple EV nanocargo, berberine, piperine, HOFs, and graphene oxide enables localized osteoarthritis modulation. The platform supports enhanced transdermal delivery together with mild hyperthermia‐associated and redox‐related responses, leading to reduced inflammation and oxidative stress, improved ...

Genetic characterization of seven clownfish species from the Jatinegara ornamental fish market using 16S rRNA DNA barcoding

Egyptian Journal of Aquatic Research
Clownfish (Amphiprion spp.) are among Indonesia’s most valuable marine ornamental fishes, yet populations are declining due to illegal and destructive fishing. Reliable species identification is essential for conservation and management.

Gardiquimod Nanoemulsion Targets Cutaneous Leishmaniasis Lesions Reducing Systemic Toxicity and Parasite Burden

Advanced Healthcare Materials, EarlyView.
Nanoemulsion delivery of a TLR7 agonist enhances safety and promotes colocalization with Leishmania‐infected macrophages in skin lesions, enabling a ∼2‐log reduction in parasite burden. However, tissue‐level constraints and TLR‐driven regulatory feedback generate a mixed immune response that limits complete parasite clearance.

qPCR for Monitoring Fish Species Authenticity in Processed Seafood

Seafood mislabeling and species substitution pose significant challenges to food authenticity, consumer trust, and public health. qPCR (quantitative Polymerase Chain Reaction) offers a sensitive and specific approach for identifying fish species in raw, processed, and mixed seafood products. By targeting species-specific DNA sequences, qPCR can rapidly
