Comparative Efficacy of Extracorporeal Versus Conventional Cardiopulmonary Resuscitation in Adult Refractory Out-of-Hospital Cardiac Arrest: A Retrospective Study at a Single Center.

Extracorporeal cardiopulmonary resuscitation (ECPR) has the potential to improve neurological outcomes in patients with refractory out-of-hospital cardiac arrest (OHCA), offering an alternative to conventional cardiopulmonary resuscitation (CCPR). However, its effectiveness in OHCA remains controversial despite advancements in resuscitation techniques. This retrospective single-center study compared neurological outcomes and 30-day survival between ECPR and CCPR patients from January 2014 to January 2022.

The Development of a One-Step PCR Assay for Rapid Detection of an Attenuated Vaccine Strain of Duck Hepatitis Virus Type 3 in Korea.

Duck hepatitis A virus type 3 (DHAV-3) is a viral pathogen that causes acute, high-mortality hepatitis in ducklings, and vaccination with attenuated live vaccines is currently the main preventive measure against it. However, differentiating infected from vaccinated animals (DIVA) is crucial for clinical diagnosis and effective disease control. This study aimed to develop a rapid mismatch amplification mutation assay PCR (MAMA-PCR) diagnostic method to simultaneously detect and differentiate between wild-type and vaccine strains.

Polydiacetylene (PDA) Embedded Polymer-Based Network Structure for Biosensor Applications.

Biosensors, which combine physical transducers with biorecognition elements, have seen significant advancement due to the heightened interest in rapid diagnostic technologies across a number of fields, including medical diagnostics, environmental monitoring, and food safety. In particular, polydiacetylene (PDA) is gaining attention as an ideal material for label-free colorimetric biosensor development due to its unique color-changing properties in response to external stimuli. PDA forms through the self-assembly of diacetylene monomers, with color change occurring as its conjugated backbone twists in response to stimuli such as temperature, pH, and chemical interactions.

Suppression of dopamine receptor 2 inhibits the formation of human prostate cancer PC‑3‑derived cancer stem cell‑like cells through AMPK inhibition.

Cancer stem cells (CSCs) contribute to the resistance of intractable prostate cancer, and dopamine receptor (DR)D2 antagonists exhibit anticancer activity against prostate cancer and CSCs. Human prostate cancer PC-3 cells were used to generate CSC-like cells, serving as a surrogate system to identify the specific DR subtype the inhibition of which significantly affects prostate-derived CSCs. Additionally, the present study aimed to determine the downstream signaling molecules of this DR subtype that exert more profound effects compared with other DR subtypes.

Clinical consequence of hypophosphatemia during antiviral therapy for chronic hepatitis B.

Background: Antiviral therapy is an essential treatment for chronic hepatitis B (CHB) infection. Although hypophosphatemia is an important adverse effect of antiviral agents, its clinical significance remains unclear. We investigated the incidence and clinical consequences of hypophosphatemia in a large cohort of CHB patients.
