Relationship Between Down Syndrome And Attention Deficit Hyperactivity Disorder And The Role Of Fkbp5 Gene: A Review Of Current Evidence, Israa A. Elsawi, Dina Salama Abd-Elmagid, Doaa Shahin, Mohamed Rizk Khodair, Sohier Yahia

Mansoura Medical Journal

The most prevalent chromosomal disorder is Down syndrome (DS). Neurodevelopmental disorders are highly associated with Down syndrome, such as attention deficit hyperactivity disorder (ADHD). Down syndrome is also distinguished by intellectual disability and developmental delays, with many affected individuals presenting manifestations of ADHD like inattention or hyperactivity. Differentiating ADHD from overlapping DS-related cognitive deficits remains a diagnostic dilemma. The FKBP5 gene, particularly the rs7748266 polymorphism, has been implicated in modulating stress response pathways linked to ADHD susceptibility. This review summarizes the relationship between DS and ADHD and explores the emerging role of FKBP5 rs7748266 in this context. This may later …

Conversion Of Orange Waste To Chemically Modified Activated Carbon Adsorbent Materials For Aqueous Phase Phosphate Removal, Sierra Mugan

Electronic Theses and Dissertations 2020 - Present

Phosphorus pollution in surface waters drives harmful algal blooms, creating ecological, public health, and economic risks. This study examined citrus processing waste as a sustainable, low-cost precursor for producing chemically modified adsorbents for phosphorus removal. Orange waste was pyrolyzed, resulting in a carbon-rich material with low ash content, as confirmed by thermogravimetric analysis. The material was modified using lanthanum chloride, iron (III) chloride, and calcium chloride at varying mass ratios and screened under standard conditions (1 mg P/L, 1 g/L dosage, 24-hour contact time). Lanthanum- and iron-modified samples demonstrated the best removal efficiencies and underwent further evaluation. The lanthanum-modified sample …

Veterans In Times Of Crisis: The Impact Of Veteran Status On Unemployment, Lubor Olsovsky

Electronic Theses and Dissertations 2020 - Present

The purpose of this research is to investigate the impact of veteran status on unemployment in times of crisis. Driven by the social identity theory, we argue that people’s identity deriving from his or her military background makes them more valuable assets in the work environment, specifically in times of crisis, because of their human capital. We utilize the coronavirus pandemic as the exogenous shock in the labor marketplace, capturing the crisis environment. Due to the veterans’ human capital driven by their leadership and entrepreneurial characteristics from their military experience, we argue that individuals with veteran backgrounds have stronger labor …
