A Modified Warthin-Starry Silver Impregnation Method to Detect Programmed Cell Death in the Interdigital Tissue of the Fetal Rat Limb

open access: yesJournal of Toxicologic Pathology, 2003
Previously we have shown that a modified Warthin-Starry (mWS) method, to which was added a minor change to prevent fading, is useful and convenient to detect chemically induced chromatin condensation during thymic apoptosis in rats treated with dexamethasone. In this study, we investigated the relationship between mWS-positive cells and programmed cell

A Study on the Inflammatory Response of the Brain in Neurosyphilis

open access: yesAdvanced Science, Volume 12, Issue 5, February 3, 2025.
This study reveals the mechanisms of inflammation and immune‐mediated brain injury in patients with Neurosyphilis (NS). By proteomic analysis of brain tissues and single‐cell sequencing of cerebrospinal fluid from NS patients, researchers identified Toll‐like/NF‐κB signaling as the key pathway involved in the damage of central nervous system in NS ...

H. Pylori‐Facilitated TERT/Wnt/β‐Catenin Triggers Spasmolytic Polypeptide‐Expressing Metaplasia and Oxyntic Atrophy

open access: yesAdvanced Science, Volume 12, Issue 3, January 20, 2025.
H. pylori infection leads repair program of the mucosa, like spasmolytic polypeptide‐expressing metaplasia (SPEM). The toxic factors of H. pylori, CagA, increased the level of TERT by disrupting the interaction between TERT and its E3 ligase, SYVN1. TERT activation of the Wnt signaling pathway leads to the occurrence of SPEM.

Isolated Positive Treponemal Test in Pregnancy and Placental Abnormalities Without Confirmed Syphilis Infection: A Case Report

open access: yesCase Reports in Infectious Diseases, Volume 2025, Issue 1, 2025.
Syphilis screening during pregnancy is essential to prevent congenital syphilis, yet diagnostic challenges arise when clinical presentation, serologic results, and pathologic examination are discordant. We report the case of a 39‐year‐old pregnant patient with a reactive enzyme immunoassay (EIA) at delivery, despite prior nonreactive syphilis ...
