In vivo antitumor activity of PHT-427 inhibitor-loaded polymeric nanoparticles in head and neck squamous cell carcinoma.

Recent studies on head and neck squamous cell carcinoma (HNSCC) tumorigenesis have revealed several dysregulated molecular pathways. The phosphatidylinositol-3-kinase (PI3K) signaling pathway is frequently activated in HNSCC, making it an attractive target for therapies. PHT-427 is a dual inhibitor of PI3K and the mammalian target of AKT/PDK1.

Biomarkers.

Background: Changes in Amyloid-β (A) and hyperphosphorylated Tau (T) in the brain and cerebrospinal fluid (CSF) precedes AD symptoms, making the CSF proteome a potential avenue to understand disease pathophysiology and facilitate reliable diagnostics and therapies.

Method: We used the Somascan assay for measuring the protein levels of 7,029 analytes in CSF of 2,286 participants from four different cohorts. We employed a three-stage analytical approach (discovery, replication, and meta-analysis).

Developing Topics.

Background: Cerebrospinal fluid (CSF) is a valuable resource for the study and diagnosis of neurological diseases, but few studies have comprehensively characterized the genetic determinants of CSF protein levels that may contribute to the development of disease. These quantitative trait loci (QTL) have proven vital to identifying candidate genes for disease treatment and monitoring. Here, we utilize our largest-to-date CSF protein QTL atlas to prioritize potentially causal proteins for 14 neurological traits and examine the unique and overlapping disease mechanisms observed using CSF proteins.

A paired study comparing mononuclear cell collection using a new in-line system with an off-line extracorporeal photopheresis apheresis system.

Background: Extracorporeal photopheresis (ECP) product characteristics are not well established. The aim of this study was to compare mononuclear cells (MNCs) collection using the new Amicus blue (AB) In-line ECP system to our standard Off-line ECP system using the Optia apheresis device and the MacoGenic G2 inactivation system (OM).

Study Design And Methods: We assessed the ECP products and procedure parameters, patient characteristics, and adverse events for both AB and OM systems in paired patients.

Photodynamic antimicrobial therapy with Erythrosin B, Eosin Y, and Rose Bengal for the inhibition of fungal keratitis isolates: An in vitro study.

Introduction: Fungal keratitis is a leading cause of corneal blindness, with current antifungal treatments having limited efficacy. One promising treatment modality is Rose Bengal (RB) photodynamic antimicrobial therapy (PDAT) that has shown mixed success against fungal keratitis. Therefore, there is a need to explore the antimicrobial efficacy of other green-light activated photosensitizers that have deep penetration in the cornea to combat the deep fungal infections, such as Erythrosin B (EB) and Eosin Y (EY).
