The objective of the research was to control the oxidative stability of lamb burgers by applying gelatin-starch active film containing java plum (Syzygium cumini) and oregano (Origanum vulgare). The films were prepared from four formulations: without extract addition (FC), with the addition of java plum extract (FJ), with the addition of oregano extract (FO) and with the addition of java plum and oregano extract (FJO). Films were characterized in terms of the physical, barrier, mechanical and antioxidant properties. The burgers were analyzed for 90 days by the physicochemical variables, lipid oxidation, and fatty acid profile. The addition of extracts in the films did not affect the tensile strength but showed low water vapor permeability. Antioxidant films with oregano extract and the blend of plant extracts were significantly more efficient than the film with java plum extract. Therefore, the active film resulted in enhanced oxidative stability of lamb burgers and may be used as primary packaging for foods.

The aim of this study was to examine the antioxidant and immunomodulatory activities of ethanol extracts from (EESC) and (EEPC). Reflux extraction was carried out using 96% ethanol on the collected plant specimens to produce EESC and EEPC.

Nanotechnology has experienced significant advancements, attracting considerable attention in various biomedical applications. This innovative study synthesizes and characterizes Ge/PLA/AuNCs (gelatin/PLA/gold nanocomposites) using Syzygium cumini extract to evaluate their various biomedical applications. The UV-Visible spectroscopy results in an absorption peak at 534 nm were primarily confirmed by Ge/PLA/AuNCs synthesis.

The aim of our research was to understand the impact of ochratoxin A (OTA) exposure on various physiological and behavioral aspects in adult Wistar rats, and to evaluate the efficacy of a essential oil (EOC) treatment in restoring the damage caused by this toxin. The essential oils were extracted by hydrodistillation, a yield of 12.70% was obtained for EOC, and the GC-MS characterization of this essential oil revealed that its principal major components are eugenol (80.

Eugenol has pharmacological properties, but its impact on renal function is limitedly studied. Thus, this study evaluated the effects of eugenol at 10, 20, and 40 mg kg, administered via gavage for 60 days, on histological, biochemical, oxidative, and proteomic parameters in rat kidneys. Adult Wistar rats treated with 10 mg kg of eugenol had kidneys with low total antioxidant capacity, high nitric oxide content, and high percentual of blood vessels, with no damage to renal function or morphology.

The Ralstonia solanacearum Species Complex (RSSC) is the most significant plant pathogen group with a wide host range. It is genetically related but displays distinct biological features, such as restrictive geography occurrence. The RSSC comprises three species: Ralstonia pseudosolanacearum (phylotype I and III), Ralstonia solanacearum (phylotype IIA and IIB), and Ralstonia syzygii (phylotype IV) (Fegan and Prior 2005).
