Article Synopsis
- Understanding the changes in cell wall components during xylem differentiation is crucial for grasping the structure of wood, especially at the secondary cell wall layer level.
- In the study of Pinus bungeana, it was found that crystalline cellulose and glucomannan were deposited before xylan and lignin, with lignification starting in the primary cell wall corners as the S layer developed.
- Immunofluorescence results showed that glucomannan was deposited earlier than xylan, and while pectins were concentrated in the primary walls, they decreased as tracheid walls differentiated, with ray cells lagging behind axial tracheids in their development.
Micromorphology and native extractive behaviour of wood powder.

Article Synopsis
- * This study examines how different milling methods and moisture levels in wood affect the microstructure and distribution of extractives in the wood powders.
- * Results indicate that wood powders from multi-blade shaft milling maintain a smoother and more intact structure, while hammer mill powders show rougher surfaces and more damage, affecting their potential use in future applications.
Factors Associated with Hypersensitivity, Management, and Treatment Options for Teeth with Molar Incisor Hypomineralisation.

Tooth hypersensitivity is a common symptom in molar incisor hypomineralisation (MIH) patients and can affect children's quality of life. During daily routine, children with MIH often report sensitivity to various thermal and mechanical stimuli, and difficulty in achieving effective analgesia is a common issue becoming a challenge for dentists. Research has focused on the possible pathophysiological mechanisms behind this phenomenon, which, in turn, have not been determined.

d-Limonene is the predominant component of essential oil from Exocarpium Citri Grandis, known for its antibacterial, antioxidant, insecticidal, and anti-inflammatory properties. The synthesis, transport, and accumulation of d-limonene in Citrus grandis 'Tomentosa' fruits are regulated by limonene synthase (LS) and its associated regulatory genes. This study addresses the gap in understanding the spatiotemporal cytological changes of LS and its regulatory genes.
