Psoriasis And Its Interplay With Liver Diseases: Evidence, Mechanisms, And Clinical Implications, Rajaa Jaber Abdel Rasul, Noor Abdulhussain Naama, Sabaa Abd Jaber, Noor Faraj Kadhem

Muthanna Medical Journal

Psoriasis is a chronic inflammatory disease of immune-related origin. It is no longer classified solely as a localized skin disorder but is now recognized as a systemic disease associated with numerous complications and co-morbidities. Recent studies have demonstrated a strong link between psoriasis and several liver diseases, particularly non-alcoholic fatty liver disease (NAFLD), non-alcoholic steatohepatitis (NASH), and cirrhosis. This association is attributed to shared pathogenic mechanisms among these diseases, including metabolic disturbances, oxidative stress, and chronic inflammation, as well as the pivotal role of inflammatory cytokines such as tumor necrosis factor-alpha (TNF-α ), interleukin-6 (IL-6), and interleukin-17 (IL-17). Recent studies …

Effects Of Tongue Resistance And Strengthening Exercises In Elderly With Mci: A Double-Blind Rct, Kuei-Ru Chou

Rsv Can Infect The Human Nasal Epithelium Via The Basolateral Route And Shows Distinct Subgroup Infectivity And Basal Cell Tropism, Ashley Murray, Divya Nagaraj, Emily M Schultz, Gina Aloisio, Erin Nicholson, Sarah E Blutt, Vasanthi Avadhanula, Pedro A Piedra

Faculty, Staff and Students Publications

Respiratory syncytial virus (RSV) causes millions of lower respiratory tract infections (LRTIs) in young children, older adults, and immunocompromised populations every year. RSV infection initiates in the upper respiratory tract and can progress to the lower airways, resulting in bronchiolitis, pneumonia, and even death. RSV primarily infects epithelial cells apically, but we hypothesized that basolateral exposure of the respiratory epithelium could provide an alternative mechanism of infection that contributes to LRTI development. Using a human nose organoid-air-liquid interface (HNO-ALI) model, we performed apical and basolateral inoculations with contemporaneous RSV strains (RSV/A/Ontario [RSV/A/ON] and RSV/B/Buenos Aires [RSV/B/BA]) representing the two RSV …

Development Of Novel Plasminogen Activators From Fragments Of Streptokinase Enzyme, Vijay G Mr

Theses and Dissertations

Thrombotic disorders such as myocardial infarction, ischemic stroke, pulmonary embolism and deep vein thrombosis remain major causes of mortality and disability worldwide, creating a continuing need for effective, safe and affordable thrombolytic therapy. Streptokinase is one of the most widely used plasminogen activators because of its activity, low cost and broad availability. However, its wider clinical utility is limited by high immunogenicity, allergic reactions, neutralizing antibody formation and poor suitability for repeat administration. This thesis aimed to develop novel streptokinase-derived plasminogen activators by identifying smaller functional fragments that retain thrombolytic activity while potentially reducing immunogenicity.

A literature-guided fragment-based strategy was …

What We Should Know About The Reliability Of Empirical Legal Studies, Kathryn Zeiler

DePaul Law Review

The findings of replication studies conducted in the early 2010s

led many to declare that science was in the midst of a “replication

crisis.” Since then, a growing number of reforms have been

proposed and tested. The field of empirical legal studies seems

behind other fields such as psychology, economics, political science,

medicine, biology, and others that have taken significant steps

toward uncovering the general reliability of the field’s empirical

work, investigating the causes of observed unreliability, and

instituting and testing the effects of various reforms. The purpose of

this Article is to summarize what we know about the reliability …
