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

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.

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.

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 ...

Carbon Dot Self‐Assembly: Bottom‐Up Fabrication, Morphological Evolution, Luminescence Regulation, and Advanced Applications

Aggregate, Volume 7, Issue 5, May 2026.
The self‐assembly of carbon dots, which enables precise control over their macroscopic architectures and collective properties, profoundly enhances their functionality. This review systematically summarizes the field through four key aspects—morphology control, luminescence modulation, assembly mechanisms, and advanced applications—and thereby offers a

Photoacclimation of cryptophytes and diatoms to light variability in the Western Antarctic Peninsula

Journal of Phycology, Volume 62, Issue 2, Page 643-665, April 2026.
Abstract Meltwater stratification during austral summer along the rapidly warming Western Antarctic Peninsula (WAP) exposes coastal phytoplankton to sudden light shifts. Such variability is thought to modulate phytoplankton dynamics, yet the photoacclimation capacity of Antarctic phytoplankton, especially cryptophytes, remains unclear.

C132-Methylation of methyl pheophorbide a and stereoselective preparation of methyl (132R)-methylpyropheophorbide a

, 2014
The (132R)-methoxycarbonyl group of methyl pheophorbide a, one of the chlorophyll-a derivatives, was converted to a methyl group through methylation at the C132 position followed by removal of the methoxycarbonyl group.
