Abstract
The present study provides the fatty acid, tocopherol, phytosterol, and polyphenol profiles of some Mediterranean oils extracted from pumpkin, melon, and black cumin seed oils and those of dietary argan seed oil. Gas chromatography analysis revealed that oleic and linoleic acids were the most abundant fatty acids. Argan and melon seed oils exhibited the highest levels of oleic acid (47.32±0.02%) and linoleic acid (58.35±0.26%), respectively. In terms of tocopherols, melon seed oil showed the highest amount (652.1±3.26 mg/kg) with a predominance of γ-tocopherol (633.1±18.81 mg/kg). The phytosterol content varied between 2237.00±37.55 µg/g for argan oil to 6995.55±224.01 µg/g for melon seed oil. High Performance Liquid Chromatography analysis also revealed the presence of several polyphenols: vanillin (0.59 mg equivalents Quercetin/100 g) for melon seed oil, and p-hydroxycinnamic acid (0.04 mg equivalents Quercetin/100 g), coumarine (0.05 mg equivalents Quercetin/100 g), and thymoquinone (1.2 mg equivalents Quercetin/100 g) for black cumin seed oil. The "Kit Radicaux Libres" (KRL) assay used to evaluate the scavenging properties of the oils showed that black cumin seed oil was the most efficient. On the light of the richness of all Mediterranean oil samples in bioactive compounds, the seed oils studied can be considered as important sources of nutrients endowed with cytoprotective properties which benefits in preventing age-related diseases which are characterized by an enhanced oxidative stress.

Abstract
Parkinson's disease (PD) is the second most common devastating neurodegenerative disorder. Presently used therapies for PD have severe side effects and are limited to only temporary improvement. Therefore, a new therapeutic approach to treat PD urgently needs to be developed. α-Lactalbumin, the most abundant milk protein in camel milk, has been attributed to various medicinal properties. This study intended to investigate the neuroprotective efficacy of the camel α-lactalbumin and oleic acid (CLOA) complex. One mechanism postulated to underlie neuroprotection by the CLOA complex is the induction of silent information regulatory protein (SIRT1). SIRT1 is known to be involved in several pathological and physiological processes, and it has been suggested that SIRT1 plays a protective role in PD. Oxidative stress, inflammation, mitochondrial dysfunction, and apoptosis are involved in PD pathogenesis. Our results revealed that SIRT1 inhibits oxidative stress by maintaining HIF-1α in a deacetylated state. SIRT1 upregulates the expression of FOXO3a and HSF-1, thus inhibiting apoptosis and maintaining the homeostasis of cellular proteins. Increased SIRT1 expression reduces the levels of TNF-α, IL-6, and IL-8, which in turn inhibits neuroinflammation. In addition to SIRT1, the CLOA complex also enhances the expression of survivin and leptin and promotes the survival of neuroblastoma cells. Altogether, our results suggest that the CLOA complex might be a novel therapeutic molecule that could ameliorate neuronal cell damage in PD.
