- Essential oils are important compounds for the prevention and/or treatment of various diseases in which solubility and bio-accessibility can be improved by nanoemulsion systems. Heracleum persicum oil nanoemulsion (HAE-NE) was prepared and biological properties were investigated against human breast cancer cells and normal human fibroblasts foreskin. Particle size, zeta potential and poly dispersity index were 153 nm, −47.9 mV and 0.35, respectively. (E)anethole (57.9%), terpinolene (13.8%), G-terpinene (8.1%), myrcene (6.8%), hexyl butyrate (5.2%), octyl bu-tanoate (4.5%) and octyl acetate (3.7%) was detected in nanoemulsion. Proliferation of cancer cells at IC50 = 2.32 µg/mL was significantly (p < 0.05) inhibited, and cell migration occurred at 1.5 µL/mL. The HAE-NE at 1.5, 2.5 and 3.5 µg/concentration up-regulated caspase 3 and enhanced sub-G1 peak of cell cycle with nil cytotoxic effects in the liver, kidney and jejunum of mice. Villus height, villus width, crypt depth and goblet cells in mice group fed with 10 and 20 mg/kg body weight of HAE-NE improved. Cellular redox state in the liver indicated 10 and 20 mg/kg body weight of nanoemulsion significantly up-regulated the expression of SOD, CAT and GPx genes. Heracleum persicum oil na-noemulsion could be an eco-friendly nanotherapeutic option for pharmaceutical, cosmetological and food applications.

- Salmonella infection is a major public health issue worldwide. Given the alarming increase in infections with antibiotic-resistant microorganisms and side effects of synthetic antibiotics, there is an increasing interest in medicinal plants as natural alternatives to synthetic drugs to combat antibiotic-resistant microorganisms. The present study investigated the biological properties and health-promoting effects of microencapsulated phenolic compounds of Teucrium polium leaves as a dietary phytobiotic in mice challenged by Salmonella enteritidis. Microcapsules showed a capsulation efficiency of 93.6% with a particle size of 1261.8 nm with antioxidant and antibacterial activities in-vitro. The phytochemical analysis confirmed the presence of various phenolic compounds, i.e., ferulic acid, cinnamic acid, gallic acid, caffeic acid, salicylic acid, catechin, ellagic acid, and chrysin ranged between 121.6 and 975.3 µg/g DW. The microencapsulated phenolics exhibited improvement in the growth, liver function, morphometric parameters of ileum, antioxidant- and inflammation-related gene expression and inhibited the ileal population of S. enteritidis in mice challenged by S. enteritidis infection. The microencapsulated phenolics from T. polium leaves could be a promising phytobiotic approach to combat S. enteritidis infections.

- The present study synthesized and evaluated the effects of nanoliposomes loaded daidzein (NLD) in diabetic mice induced by alloxan. Five groups of Balb-c mice were treated for 5 weeks (Group 1 and 2 referred to as normal and diabetic control receiving normal feed). Group 3 and 4 were diabetic mice receiving 50 and 100 mg/kg/BW NLD respectively. Group 5, diabetic mice, received the standard drug, Metformin, 250 mg/kg/BW per day orally. Results indicated that NLD significantly (p < 0.05) improved the final body weight, triglyceride (TG), total cholesterol (TC) concentrations, low-density lipoprotein cholesterol and malondialdehyde (MDA) levels and enhanced the high-density lipoprotein. Furthermore, NLD enhanced the expression of CAT and suppressed iNOS gene in the pancreas. The mRNA expression of GLUT2 and GLUT4 also showed increase in the diabetic mice. Findings demonstrated the potential of NLD as a nutraceutical for the prevention and/or treatment of diabetes without toxic side effects.

- Cadmium is a poisonous trace element which induces oxidative stress and pollutes the environment. Nanoemulsions are recognized as a new drug delivery system with enhanced therapeutic efficacy. In the present study, nanoemulsion of Thymus vulgaris essential oil was prepared and characterized. The effects of the essential oil on body weight gain, liver mineral content, histopathology, lipid peroxidation, antioxidant- and inflammatory-related gene expressions were also investigated in mice challenged by cadmium-induced oxidative stress. Characterization of nanoemulsion (e.g., polydispersity index, particle size, and ζ-potential) indicated a good stability degree of T. vulgaris essential oil. Phytochemical analysis by GC–MS also demonstrated T. vulgaris essential oil contained phenolic compounds i.e., thymol, p-cymene, ɣ-teripinene, carvacrol, caryophyllene and linalool. The treatment of mice with T. vulgaris essential oil significantly (p < 0.05) improved body weight changes, reduced cadmium deposition in the liver and decreased lipid peroxidation compared to control group. Also, the antioxidative potential was enhanced whereas inflammation in the tissues were suppressed. The GPx gene was up regulated whereas iNOS genes were significantly (p < 0.05) downregulated in kidney, liver and brain tissues. Our findings suggest T.vulgaris essential oil can be a promising protective agent against cadmium-induced oxidative stress.

- The application of nano drug delivery systems, particularly those utilizing natural bioactive compounds with anticancer properties, has gained significant attention. In this study, a novel nano-phytosome-loaded phenolic rich fraction (PRF) derived from Allium ampeloprasum L. was developed. The antitumor activity of the formulation was evaluated in BALB/c mice with TUBO colon carcinoma. The PRF-loaded nano-phytosome (PRF-NPs) exhibited a sphere-shaped structure (226 nm) and contained a diverse range of phenolic compounds. Animal trials conducted on TUBO tumor-bearing mice demonstrated that treatment with PRF-NPs at a dosage of 50 mg TPC/Kg/BW resulted in significant improvements in body weight and food intake, while reducing liver enzymes and lipid peroxidation. The expression of apoptosis-related genes, such as Bax and caspase-3, was upregulated, whereas Bcl2 was significantly downregulated (p < 0.05). Furthermore, the expression of GPx and SOD genes in the liver was notably increased compared to the control group. The findings suggest that the phytosomal encapsulation of the phenolic rich fraction derived from Allium ampeloprasum L. can enhance the bioavailability of natural phytochemicals and improve their antitumor properties. The development of PRF-NPs as a nano drug delivery system holds promise for effective breast cancer treatment.

- The present study aimed to develop a fermented food (idli) with enhanced gamma-aminobutyric acid (GABA) and angiotensin I-converting enzyme (ACE) inhibitory properties using a GABA-producing fungus. Aspergillus oryzae NSK fermented idli batter and GABA was maximized (451.7 mg kg(-1)) in 120 h. The ACE inhibitory, 2,2-diphenyl-1-picryl-hydrazyl-hydrate (DPPH) free radical scavenging and nitric oxide radical scavenging activities increased to 41.8%, 1.9 and 0.6 mu mol trolox equivalent antioxidant capacity (TEAC) per gram in 120 h, respectively. In contrast, phytic acid and trypsin inhibitor activities decreased to 3.01 g kg(-1) and 30.8 mg kg(-1), respectively. The systolic blood pressure of spontaneously hypertensive rats in the fermented idli diet group was lower than those fed a plain idli diet. Lipid peroxidation in the plain idli diet group was significantly higher, whereas superoxide dismutase and glutathione reductase activities were significantly lower. The expression of genes ET-1, HSP70, NF-kappa B and iNOS in the aorta of SHRs that received GABA-containing diets was down-regulated between 2.2 and 3.8 fold. The production of GABA-enriched foods can be a promising approach to lower the blood pressure of spontaneously hypertensive rats.
