Aromatic hydrocarbons are rightly considered to belong to most active synthetic interferon inducers among low molecular compounds. A comparative evaluation of L-1 (acridanon) and amixin (fluorenon) showed L-1 to have more marked interferon-inducing properties. Both compounds differed not only in the dynamics and levels of interferon synthesis in different organs which suggests the possibility of their employment in different diseases, but also in the efficacy of the modes of application. L-1 induced IF synthesis most actively after subcutaneous inoculation, amixin after oral administration.

Background: Pharmacoepidemiologic studies assessing drug effectiveness for Alzheimer's disease and related dementias (ADRD) are increasingly popular given the critical need for effective therapies for ADRD. To meet the urgent need for robust dementia ascertainment from real-world data, we aimed to develop a novel algorithm for identifying incident and prevalent dementia in claims.

Method: We developed algorithm candidates by different timing/frequency of dementia diagnosis/treatment to identify dementia from inpatient/outpatient/prescription claims for 6,515 and 3,997 participants from Visits 5 (2011-2013; mean age 75.

Background: The vicious cycle between depression and dementia increases the risk of Alzheimer's Disease (AD) pathogenesis and pathology. This study investigates therapeutic effectiveness versus side effects and the underlying mechanisms of intranasal dantrolene nanoparticles (IDNs) to treat depression behavior and memory loss in 5XFAD mice.

Method: 5XFAD and wild-type B6SJLF1/J mice were treated with IDNs (IDN, 5 mg/kg) in Ryanodex formulation for a duration of 12 weeks.

Background: In Alzheimer's Disease trials, the Mini-Mental State Examination (MMSE) and Clinical Dementia Rating (CDR) are commonly utilized as inclusionary criteria at screening. These measures, however, do not always reaffirm inclusionary status at baseline. Score changes between screening and baseline visits may imply potential score inflation at screening leading to inappropriate participant enrollment.

Background: Glucagon-like peptide 1 (GLP-1) is a peptide hormone that plays several physiological roles in treating diabetes and in protecting the brain. Recent clinical trials testing 4 different GLP-1 class drugs in phase 2 trials showed a clear correlation between neuroprotection and the ability to cross the BBB. Exenatide and Lixisenatide both showed excellent protective effects in patients Parkinson's disease (PD) and both drugs can readily cross the BBB.

Background: Vaxxinity is developing an active immunotherapy targeting Tau for Alzheimer's disease (AD) and other tauopathies. VXX-301 is a multi-epitope vaccine designed to target the N-terminal and repeat domains of Tau. This design enables targeting multiple forms of Tau thought to contribute to Tau associated pathologies.
