While motor impairments in PD are well-established, the impact of chronic circadian misalignment on both motor and cognitive dysfunctions remains underexplored. This study investigates the effect of prolonged exposure to different lighting conditions on MPTP-induced motor and cognitive deficits in a rat model. A total of 100 adult male Wistar rats were divided into five groups with different light-dark cycle conditions: standard 12-h light/12-h dark (12 L:12D), constant light (24 L), constant darkness (24D), 20-h light/4-h dark (20 L:4D), and 4-h light/20-h dark (20D:4 L). After 60 d of exposure to these conditions, each group was further divided into Parkinsonian (MPTP-treated) and non-Parkinsonian (saline-treated) subgroups. MPTP hydrochloride (25 µg/kg) was administered intranasally to induce Parkinsonism. Behavioral assessments, including the beam balance test, open field test, Y-maze test, and shuttle box test, were conducted to evaluate motor coordination and cognitive function. Immunohistochemical analyses of α-synuclein (α-syn) accumulation in the substantia nigra (SNc) and tyrosine hydroxylase (TH) expression in the suprachiasmatic nucleus (SCN) were performed. Data were analyzed using t test, one-way ANOVA and Tukey's post hoc test. MPTP administration significantly impaired motor function, as evidenced by increased crossing time in the beam balance test (<i>p</i> < 0.001) and reduced locomotor activity in the open field test (<i>p</i> < 0.01). Prolonged exposure to different lighting conditions further exacerbated these deficits, particularly in the 24 L and 20 L:4D groups (<i>p</i> < 0.0001). Cognitive assessments revealed that MPTP-treated rats exhibited marked deficits in working memory (Y-maze, <i>p</i> < 0.05) and associative learning (shuttle box, <i>p</i> < 0.01), with the most severe impairments observed in groups subjected to extreme light-dark alterations. Immunohistochemical analyses demonstrated significantly increased α-syn accumulation in the SNc (<i>p</i> < 0.0001) and decreased TH expression in the SCN (<i>p</i> < 0.001), particularly in MPTP-treated rats under photoperiod disruption. Chronic photoperiod disruption exacerbates MPTP-induced motor dysfunction, cognitive impairment, and neurodegeneration.

A population-based sample of 330 Arabic-speaking participants from Lebanon, comprising 67.3% females with a mean age of 21.75 ± 2.43 years (range: 18-33), were recruited for this study. The participants were asked to fill out an online questionnaire consisting of the Arabic versions of the rMEQ, Pittsburgh Sleep Quality Index (PSQI), and the Lebanese Anxiety Scale (LAS). Confirmatory factor analysis (CFA) indicated a modest fit for the one-factor model of the rMEQ. Internal reliability was good, with ω = .75 and α = .70. Additionally, cross-sex invariance analysis showed support for configural, metric, and scalar invariance, with no significant differences in rMEQ scores between males and females. Concurrent validity revealed significant moderate correlations between higher rMEQ scores and lower depression, better sleep quality, and lower anxiety. The Arabic version of the rMEQ demonstrated adequate psychometric properties in a Lebanese adult population. The CFA results support a one-factor model of the Arabic rMEQ, similarly as in the case of other language versions.

However, further genetic analysis will be required to clearly define the role of these proteins in the carp clock mechanism. We have found that the central oscillator function in carp is primarily performed by the retina, which is characterized by strong endogenous rhythmicity of activity.

The gut microbiome plays a crucial role in metabolic homeostasis by producing metabolites - such as short-chain fatty acids, secondary bile acids, and microbial-associated molecular patterns - that influence nutrient absorption, immune responses, and host metabolism in alignment with circadian rhythms. This review explores how circadian disruptors influence the human gut microbiome, focusing on changes in microbial composition, diversity, and functionality, and their implications for metabolic health. Preclinical studies demonstrate that circadian disruptions alter microbial composition, reduce rhythmicity, and impair functionality, contributing to metabolic disorders. However, human studies often report inconsistent findings, with microbial functionality appearing more sensitive to disruptions than composition. Eating patterns affect both the gut microbiome and circadian alignment; their optimization could realign microbial and host rhythms to promote metabolic homeostasis. Future research should focus on longitudinal and interventional studies using advanced methodologies, such as real-time intestinal gas measurements, to capture dynamic microbial activity in humans.
