Summary: This study investigated the effects of different concentrations of zinc and copper on the growth and biochemical indices of summer squash. High concentrations of copper intensified oxidative stress and decreased plant yield and productivity. However, the co-application of copper and zinc alleviated stress intensity and improved the plant's economic yield and physiological parameters.

Summary: To address the issue of natural dyes' susceptibility to photofading, researchers developed a durable SiO2@PVP layer on a sodium copper chlorophyllin (SCC) dyed fabric pre-coated with polyvinyl pyrrolidone (PVP). This layer, formed by in-situ growing SiO2 nanoparticles (NPs) with a diameter of 50 nm, successfully inhibited the photofading of the dye.

Summary: Cancer remains a major cause of death worldwide, and early diagnosis is critical for improved survival rates and treatment success. Studies have shown that cancer patients generally have elevated serum copper levels and diminished zinc levels, with inconsistent changes in selenium and iron levels depending on the type of cancer. Further research is needed to investigate whether these element concentrations can predict the survival probability of cancer patients.

Summary: This study investigates the evolution of functionalities and structure of activated carbon (AC) generated from pine needles activated with ZnCl2 at different temperatures. The results show that ZnCl2 can catalyze the dehydration, condensation, and aromatization reactions of sugary structures, leading to a significant increase in the yield of solid product (AC), and the resulting AC exhibits a high sensitivity to temperature. Furthermore, ZnCl2 can also catalyze the dehydration of hydroxyl group and the conversion of carbonyls in aldehydes/ketones. However, above 500 degrees C, the transformation of ZnCl2 to ZnO leads to the loss of catalytic activity.

Summary: Effective delivery of the biostimulant sodium copper chlorophyllin (Cu-chl) into plants was achieved using hybrid nanovesicles based on sodium dodecylbenzenesulfonate (SDBS) and cetyltrimethylammonium bromide (CTAB). These nanovesicles exhibited small particle size, good colloidal stability, controllable release rate, improved photostability of Cu-chl, and significant penetration into the plant root without causing significant phytotoxicity.

Summary: This article reviews various efforts made to tackle the issue of pine needle waste. Pine needles have been utilized in composite materials, water purification, electronic devices, etc. Gasification, pyrolysis, saccharification combined with fermentation, and catalyst-assisted pyrolysis are promising techniques for converting pine needles into bio-energy and water purification materials. Nano cellulose extracted from pine needles exhibits appealing thermal and mechanical strength. Studying the magnetic properties of pine needles provides insights into air quality in the surrounding environment, and packaging materials made from pine needles have exceptional ethylene scavenging abilities.

Summary: In this study, a novel thermally stable, strongly basic resin with a cross-link biguanide structure was synthesized and investigated. The resin showed optimal thermal stability and adsorption capacity for separating sodium copper chlorophyllin (SCC) from plant extract. Results indicated that the main adsorption affinity of the resin towards SCC was due to the synergistic effects of hydrophobic and ionic interactions. The rise in temperature benefited the adsorption equilibrium. A high-purity SCC extract was successfully prepared using this resin.

Summary: The study demonstrates that tobacco plants with reduced zinc levels exhibit accumulation of phosphorus, iron, manganese, and copper in their leaves, as well as stunted growth. Transcriptional analysis reveals local zinc deficiency and FIT1-mediated iron deficiency responses in leaves. Additionally, a phosphate-starvation response and upregulation of aquaporin genes are associated with the abnormal growth phenotype in affected plants.

Summary: The present study investigated the anti-tyrosinase activity, mechanism, and antioxidant capacity of proanthocyanidins (PAs) from Pinus thunbergii needles. Results showed that PAs primarily consisted of catechin/epicatechin and effectively inhibited the tyrosinase activity. Additionally, various experiments confirmed the strong antioxidant properties of PAs. Therefore, PAs from Pinus thunbergii needles have the potential to be utilized as a new tyrosinase inhibitor in the food, medicine, and cosmetics industries.

Summary: Moisture and amylose content play crucial roles in determining the quality of heat-treated starches. Increasing moisture content leads to higher paste transmittance, gelatinization temperature, and digestibility, while decreasing swelling power and enthalpy. Higher amylose content in rice starch decreases molecular order and gelatinization temperature, but increases resistant starch.

Summary: The present study examined the structure of acorn starch and how non-starch nutrients affect its physicochemical properties and digestibility. Results showed that the crystallinity of acorn flour decreased after various treatments, which also led to a decrease in gelation temperature and reduced interactions between starch granules. Endogenous proteins, fats, and beta-glucans played a key role in reducing the digestibility of acorn starch by forming complexes and inhibiting hydrolysis.

Summary: This study investigated the methods of production and storage of air-dried chestnut kernels. It was found that the browning of chestnut kernels could be inhibited by the use of 1.5% EDTA-2Na, 1% pullulan, and 1% L-cysteine. The study also revealed that different packaging and storage conditions affected the degree of browning and shelf life of the chestnut kernels. Through prediction models, the longest predicted shelf lives of the chestnut kernels under different storage conditions were determined to be 105.3 days (PB2), 19.5 days (PB3), and 10.8 days (PB1).
