In the present study, the physicochemical, mechanical, and functional properties of biodegradable pectin/cudlan gum polysaccharide films with CBG oil were evaluated. In these studies, the TS values for the films ranged from 8.50 MPa to 14.80 MPa. The EB values ranged from 33.06% to 39.07%. The WVTR ranged from 13.7 to 9.51 g/m2 d. In all the films tested, the change in the L* parameter did not change significantly statistically (p ≥ 0.05). In films with low CBG content (0.125F, 0.25F, 0.35F), L* remained stable, which indicated their resistance to darkening. However, film 0.5F was an exception, as it showed a decrease in L*, suggesting darkening or photodegradation processes. CBG films reduced mold growth, water loss, color degradation, and anthocyanin content in stored fruit, especially films with a content of 0.125F–0.35F, while higher concentrations (0.5F–0.75F) could cause pro-oxidative effects. Soil application of the film showed that moderate CBG concentrations (0.25F–0.35F) increased the content of chlorophyll, carotenoids, and phenols, indicating biostimulating potential, while the highest concentrations could cause oxidative stress. At the highest CBG concentration (0.75F), the carotenoid content decreased to 0.054–0.113 mg·g−1 FW. At higher concentrations of active substances in the film (0.5F and 0.75F), stabilization or a decrease in O2•− levels was observed, which may indicate the effective activation of protective mechanisms leading to the neutralization of excess free radicals.

For centuries, mushrooms have been used as a component of skincare formulations. Environmental stresses and a modern lifestyle expose the skin to accelerated aging. To slow down this process, natural anti-aging skincare ingredients are being sought. In this review, 52 scientific publications about the effects of chemical compounds extracted from the fruiting bodies of macrofungi on skin cells were selected. The effects of extracts from nine species that are tested for anti-aging effects have been described. According to available literature data, macrofungi contain many polysaccharides, phenolic compounds, polysaccharide peptides, free amino acids, sterols, proteins, glycosides, triterpenes, alkaloids, which can have an anti-aging effect on the skin by acting as antioxidants, photoprotective, skin whitening, moisturizing, anti-inflammatory and stabilizing collagen, elastin and hyaluronic acid levels in the skin.

Streszczenie          Algi są różnorodną grupą organizmów, występującą najczęściej w środowisku wodnym. Wśród nich wyróżniamy różne typy filogenetyczne, między innymi: sinice, zielenice, brunatnice i krasnorosty. Algi stanowią naturalne źródło wielu substancji odżywczych, w tym białek, witamin, kwasów tłuszczowych, mikro- i makroelementów. Ich metabolity cechuje wielokierunkowa aktywność biologiczna: przeciwzapalna, antyoksydacyjna, antybakteryjna a także, według niektórych badań przeciwnowotworowa. Potwierdzają to wyniki badań o charakterze in vitro oraz in vivo. Ze względu na wysoką wartość odżywczą oraz potencjał prozdrowotny, niektóre algi otrzymały status żywności funkcjonalnej. Algi stosowane są również jako dodatki do żywności i w przemyśle biopaliwowym. Znalazły zastosowanie w lecznictwie między innymi jako składnik opatrunków. Do produktów kosmetycznych algi dodawane są ze względu na działanie przeciwstarzeniowe, a także fotoprotekcyjne. Niniejsza praca omawia pozycję systematyczną alg, ich budowę i wytwarzane związki chemiczne, a także charakteryzuje algi jako grupę organizmów o interesującym potencjale biologicznym oraz wysokiej przydatności do wykorzystania w różnych gałęziach przemysłu.

Mushrooms are rich in bioactive compounds with antiaging properties. This study focused on three species: Hericium erinaceus, Ganoderma lucidum, and Coprinus comatus. Their antioxidant and anti-tyrosinase activities were evaluated using ABTS, CUPRAC, and DPPH assays. Ganoderma lucidum showed the highest ABTS activity (97.09%), followed by Coprinus comatus (83.35%) and Hericium erinaceus (60.53%). In the CUPRAC assay, Ganoderma lucidum demonstrated the greatest Cu2+ reduction at 3.0 mg/mL, while Hericium erinaceus and Coprinus comatus showed similar reduction levels at higher concentrations. The DPPH assay revealed Ganoderma lucidum as the most potent antioxidant (90.83%), with the other two species exhibiting around 45% lower activity. Ganoderma lucidum also had the highest tyrosinase inhibition. Among the extracts, Coprinus comatus ethanol extract was most toxic, especially to Daphnia pulex and Chironomus aprilinus, with 50% mortality occurring within approximately 8 hours and 40 minutes, respectively. Hericium erinaceus ethanol extract was the least toxic, affecting only Daphnia pulex with four deaths after 24 hours. Aqueous extracts from all fungi showed no toxicity. These findings suggest that mushroom extracts, particularly Ganoderma lucidum, have potential for use in antiaging

The invasive pest Cameraria ohridella annually colonizes trees of the genus Aesculus across Europe, causing dark brown damage called mines that gradually cover the leaf surface. This study aimed to compare the VOC profiles emitted by chestnut tree leaves with varying susceptibility to the pest and assess whether these profiles change due to larval feeding. The research involved a susceptible tree (Ae. turbinata) and resistant trees (Ae. glabra and Ae. parviflora). Over three growing seasons (2014, 2015, 2016), leaf damage and the profile of VOCs were analyzed biweekly from May to September. Leaf damage increased progressively in Ae. turbinata during all seasons. The VOC profiles differed both qualitatively and quantitatively among the trees and across years. More VOCs were identified in 2014 and 2015 than in 2016. The susceptible Ae. turbinata exhibited the highest VOC diversity in 2014, aligning with severe leaf damage—profiles of VOCs in Ae. turbinata were different from resistant trees. Statistical analysis revealed that in 2014 and 2015, differences in the profile of VOCs between susceptible and resistant trees were apparent near pest-feeding dates. In 2016, VOCs significantly distinguished the profile of susceptible trees that were present before the appearance of the first generation of the pest.
