Summary: There are significant differences in leaf epidermal structure between young and mature plants of Solanum rostratum, including stomata density, trichome density, and wax content. These differences lead to variations in herbicide permeability, water loss, and herbivory.

Summary: This study explored the native cuticle and epidermal layer of Norway spruce needles using Raman imaging and polarization experiments. Results showed a waxy, crystalline layer on top and strong signals of coumaric acid and flavonoids in the lipidic amorphous cuticle beneath. Non-negative matrix factorization provided the purest component spectra and promoted band assignments, enhancing our understanding of plant cuticle structure and composition.

Summary: High-melting hydrocarbon waxes have unique features and find applications in various industries. However, their supply is insufficient in the current market. Research in this field focuses on the synthesis techniques of PE waxes, FTS waxes, and biomass-derived waxes, as well as catalysts and reaction mechanisms involved in their synthesis.

Summary: This study demonstrated that paclitaxel affects healthy human epidermal cells, impairing various cellular processes such as inflammation, oxidative stress, apoptosis, and reduced vascular tube formation. Toll-like receptor 4 activation is involved in mediating some of these adverse effects on skin.

Summary: Inspired by the biological self-recovery mechanism of superhydrophobicity, a new class of waxgel material has been reported, which features sustainable hierarchical surface micro-structures and the ability to self-reconstruct its surface layer after damage or removal. This material does not require external input for self-recovery and exhibits durability and non-fluorinated composition.

Summary: The regeneration capacity of Amelanchier alnifolia var. cusickii and Lonicera kamtschatica cv. 'Jugana' is influenced by the concentrations of plant growth regulators and types of explants. Both species can regenerate shoots from internodal segments and petioles.

Summary: The study found that the cuticle can reversibly modify its transpiration barrier under prolonged drought and rehydration treatments by selectively depositing specific wax compounds; these modifications are achieved through multiple mechanisms, helping to strengthen or maintain the protective function of the cuticle.

Summary: Skin toxicity caused by paclitaxel could be underestimated as the adverse events may appear asymptomatic. This study found that paclitaxel alters gene and protein expression related to skin markers, and impairs the physical, physiological, and biomechanical properties of the skin in gynecological cancer patients. Prophylactic measures should be taken to prevent these subclinical alterations and potential adverse reactions.

Summary: The study on tea trees found that the epicuticular wax coverage on the leaf surface is positively correlated with resistance, and different tea trees may be affected by different cuticular factors under different conditions.

Summary: This study investigates the melting and crystallization behavior of a blend of Fischer-Tropsch wax and high-flow linear low-density polyethylene. The results show that increasing the wax content delays crystallization, reduces overall crystallinity, and decreases the size of the polyethylene-rich phase crystallites. The variation of zero-shear viscosity with blend composition indicates that the chains are in an entangled state in a homogeneous melt, suggesting that the wax and LLDPE are miscible in the melt and partially compatible in the solid state.

Summary: This study demonstrates the expression of functional protease-activated receptor 2 (PAR2) in human induced pluripotent stem cell-derived keratinocyte-like cells (iKera). Activation of PAR2 in iKera leads to calcium release and the release of proinflammatory cytokine tumor necrosis factor alpha. The study also indicates crosstalk between the PAR2 and IL-4 inflammatory axes in iKera, suggesting its potential as a drug screening platform for atopic dermatitis.

Summary: The aim of this paper is to present edible coatings based on lipids and their application in the food industry. The paper discusses different types of plant waxes, the advantages and disadvantages of edible coatings based on plant waxes, and the application of edible coatings based on lipids in the food industry. It also introduces the use of popular plant waxes such as Carnauba wax and Candelilla Wax in the composition of edible coatings. The paper proposes an effective method for the industrial extraction/separation of plant wax from the cuticle and waste peels of fresh fruits and vegetables.

Summary: This study aims to enhance the use of agricultural byproducts for the production of bio-composites through melt extrusion. The adhesion between a polylactic acid/poly(butylene succinate) blend and rice and wheat bran platelets was improved by treating the fillers with beeswax. The coupling action of beeswax and inorganic fillers was also investigated for improving the thermo-mechanical properties of the composites. The optimal formulation was selected based on various characterizations and analytical models.
