Transmission electron microscopy characterisation of Spirulina bioplastics

Journal of Microscopy, Volume 303, Issue 1, Page 101-119, July 2026.
Abstract Plastic pollution is impacting global ecosystem health. Bioplastics made from unprocessed biomass, including whole or fragmented tissues, are one potential solution. They are biodegradable and exhibit competitive mechanical performance. Seaweed and microalgae have gained popularity over the last decade as bioplastic feedstocks due to their ...

Using Principal Components Analysis to Visualize Motion and Mitigate Artifacts in Dynamic Optical Coherence Tomography

Journal of Biophotonics, Volume 19, Issue 6, June 2026.
We demonstrate that Principal Component Analysis (PCA) can be used in dynamic OCT to substantially reduce artifacts from strong specular reflections, isolate movement within the sample, and create thin, histology‐like images, thereby avoiding the need for complex, time‐consuming techniques used in clinical histopathology.

Raman Microscopy at the Organic–Inorganic Interfaces in Human Calcified Aortic Valves Shows the Co‐Existence of Whitlockite Crystals and Carbonated Hydroxyapatite‐Mineralized Collagen Fibrils

Advanced Functional Materials, Volume 36, Issue 42, 26 May 2026.
This study advances our understanding of aortic valve stenosis by capturing spatially resolved chemical and structural changes at the nanoscale. The findings highlight the potential of combined Raman and electron microscopy for understanding calcification mechanisms across diverse tissue types.

Investigating the Therapeutic Potential of Tamarix aphylla Leaf Extract Against Toxicity Caused by Graphene Nanosheets in Cirrhinus mrigala

Veterinary Medicine and Science, Volume 12, Issue 3, May 2026.
Tamarix aphylla leaf extract significantly alleviated graphene nanosheet–induced toxicity in Cirrhinus mrigala, reducing oxidative tissue damage and restoring organ integrity. Rich in antioxidant compounds, the extract offers a promising natural strategy for mitigating the biological impacts of graphene‐related pollutants.

Pulp Fiber Bending Stiffness in Wet and Dry State Measured from Moment of Inertia and Modulus of Elasticity

BioResources, 2014
The bending stiffness of pulp fibers in both dry and wet states is of great importance with respect to many optical and physical paper properties. We introduce a method that evaluates fiber bending stiffness from the fibers’ Young’s modulus (E) and the ...

Therapeutic Effect of Photobiomodulation and Single Intratendinous Injection at the Lesion Site of Platelet‐Rich Fibrin in Inducted Tendinopathy

Journal of Biophotonics, Volume 19, Issue 4, April 2026.
Combined photobiomodulation and platelet‐rich fibrin accelerate early functional recovery and enhance collagen synthesis and angiogenesis in acute tendon injury, despite increased initial inflammation. PBM alone improves structural organization, while PRF promotes faster recovery, supporting stage‐specific therapeutic strategies for optimized tendon ...

Stem anatomy in Passiflora (Passifloraceae): from woody climbers to herbaceous vines [PDF]

Plant Ecology and Evolution
Background and aims – Tendril-climbing vines are widespread within the genus Passiflora, but in P. subg. Astrophea, the basal clade, different growth forms are observed, varying from trees to woody vines, in contrast to the herbaceous climbers of the ...
