Turicibacter and Catenibacterium as potential biomarkers in autism spectrum disorders.

Autism spectrum disorders (ASD) are neurodevelopmental disorders characterized by social, behavioral, and cognitive impairments. Several comorbidities, including gastrointestinal (GI) dysregulations, are frequently reported in ASD children. Although studies in animals have shown the crucial role of the microbiota in key aspects of neurodevelopment, there is currently no consensus on how the alteration of microbial composition affects the pathogenesis of ASD.

Correlational Insights into Attention-Deficit/Hyperactivity Disorder in Lebanon.

Attention-Deficit/Hyperactivity Disorder (ADHD), a prevalent childhood neurodevelopmental disorder with complex etiology involving genetic and environmental factors, causes impairments across various life domains and substantial social and economic burden. Identifying correlates to prevent its onset and decrease its incidence is crucial. To our knowledge, our study represents the first case-control investigation of Lebanese ADHD patients to explore potential correlations between familial, maternal, and child health variables and ADHD to enhance understanding of its etiology and aid in prevention efforts.

Systems Biology Modeling of Cancer Nonlinear Dynamics.

Not unlike the climate or what holds the galaxies and planetary motions together, cancer biology has an intrinsic nonlinear dynamic. In this overview we will outline how to connect temporal measurements of a nonlinear dynamical and unstable complex system, such as cancer, with well-established engineering methods, old and new, that are applied in linear dynamical systems.This proof-of-concept is therapeutically relevant in the development of new means to treat or control human cancer by either adding an appropriate external "damping" or a "forcing" term, or by a "control" actuator such that its nonlinear dynamic is steered to a spiral stably into zero forever as a sink attractor.

Letter and Category Fluency: Normative Data for Lebanese Older Adults.

Background: Verbal fluency tasks are frequently used for neuropsychological assessment in clinical practice and research. It consists of two tasks namely category and letter fluency tests.

Objective: To determine normative values in category (animals, vegetables, fruits) and letter fluency [Mim () "M", Alif () "A", Baa () "B"] tasks in Arabic language in 60 s.
