Antimicrobial photodynamic therapy in Candida spp. biofilms: In vitro and in vivo protocols

Photochemistry and Photobiology, EarlyView.
This review addresses the critical challenges in translating in vitro antimicrobial photodynamic therapy protocols to in vivo models, with a particular focus on the hurdles of standardization. The vast diversity in photosensitizers and light parameters across different target cells and models requires a rigorous optimization process.

PheophorbideaContent and Chlorophyllase Activity in Green Tea [PDF]

Bioscience, Biotechnology, and Biochemistry, 1998
We investigated the total content of pheophorbide a (PB a), which is sum of the contents of newly produced PB a, including PB a initially present and that converted from chlorophyllide a (Chd a) by the chlorophyllase reaction during incubation, in green tea samples, and found that the total content of PB a markedly increased in both Sencha and Matcha ...

The effect of photodynamic therapy in head and neck cancer: A comprehensive review of in vivo models

Photochemistry and Photobiology, EarlyView.
This review evaluates Photodynamic Therapy (PDT) in in vivo head and neck cancer models. PDT effectively generates ROS, reducing tumor growth, cell proliferation and angiogenesis while enhancing survival and immune responses. However, methodological heterogeneity highlights the urgent need for standardized dosimetric protocols to ensure reproducibility

Chitosan‐Carbon Dot Composite Materials Form a Leaf Surface Barrier to Mitigate the Enrichment and Invasion of Nanoplastics: From Leaf Interface to Systemic Response

Advanced Science, Volume 13, Issue 39, 13 July 2026.
Foliar spraying of CS‐CDs can form a film on the leaves of Brassica rapa, effectively reducing the enrichment and absorption of PS in the leaves, while increasing the biomass and nutrient content of the plants. In addition, CS‐CDs can also enrich the interfoliar microbial community and activate the plant's own defense metabolic pathways.

Photodynamic Therapy Using Pheophorbide a and Nd:YAG Laser

Neurologia medico-chirurgica, 1991
The authors describe a new photodynamic therapy (PDT) method for malignant brain tumors. Pheophorbide a (Ph-a), the photosensitizer, has low toxicity, causes no skin sensitization and is activated with an acoustic Q switched neodymium yttrium-argon-garnet (Nd:YAG) laser which achieves deep tissue penetration.

Propagation of cell death in dropdead1, a sorghum ortholog of the maize lls1 mutant. [PDF]

PLoS ONE, 2018
We describe dropdead1-1 (ded1), an EMS-induced recessive lesion mimic mutant of sorghum. It is characterized by the formation of spreading necrotic lesions that share many attributes with those associated with the maize lethal leaf spot1 (lls1) and ...

Ulva lactuca Extract in Confectionery Systems: A Sustainable Approach to Natural Pigmentation, Antioxidant Enrichment, and Sensory Optimization in Fondant and Meringue Matrices

Food Science &Nutrition, Volume 14, Issue 7, July 2026.
This study evaluated the functional potential of Ulva lactuca extract as a natural colorant and antioxidant incorporated into sugar‐based (fondant) and aerated (meringue) confectionery matrices. Extract incorporation significantly enriched total phenolic content—achieving up to 150.95 mg GAE/100 g dry matter in meringues—and surged antioxidant ...

Mechanistic Insights Into Color and Texture Stability of Frozen Tropical Vegetables: Processing, Modeling, and Preservation Strategies

Food Science &Nutrition, Volume 14, Issue 6, June 2026.
This review elucidates the mechanistic pathways governing color and texture degradation in frozen tropical vegetables, emphasizing pigment oxidation, enzymatic softening, and ice crystal‐induced structural damage. It integrates kinetic, Arrhenius, RSM, and machine‐learning models with advanced preservation strategies to optimize freezing processes ...

A naturally occurring epiallele associates with leaf senescence and local climate adaptation in Arabidopsis accessions

Nature Communications, 2018
Epigenetic variation underlies various aspects of phenotypic diversity of plants. Here, He et al show a naturally occurring epiallele controls Arabidopsis leaf senescence by regulating the expression of PHEOPHYTIN PHEOPHORBIDE HYDROLASE (PPH), and is ...

Vacuolization as a Novel Approach to Cancer Therapy

Journal of Biochemical and Molecular Toxicology, Volume 40, Issue 6, June 2026.
This review discusses the novel strategy of inducing vacuole formation in cancer cells using small molecules, that induce nonapoptotic cell death mechanisms, such as paraptosis, oncosis, autophagy, and methuosis, and its potential in overcoming resistance to apoptosis‐based cancer therapies.
