Purpose: We aimed to investigate the role of gallic acid treatment on spinal cord tissues after spinal cord injury (SCI) and its relationship with endoplasmic reticulum (ER) stress by histochemical, immunohistochemical, and in-silico techniques.
Methods: Thirty female Wistar albino rats were divided into three groups: sham, SCI, and SCI+gallic acid. SCI was induced by dropping a 15-g weight onto the exposed T10-T11 spinal cord segment.
Diagnostic value of glypican-1; a new marker differentiating pulmonary squamous cell carcinoma from adenocarcinoma: immunohistochemical study on Egyptian series.

Lung cancer is one of the major causes of cancer morbidity and mortality. Subtyping of non-small cell lung cancer is necessary owing to different treatment options. This study is to evaluate the value of immunohistochemical expression of glypican-1 in the diagnosis of lung squamous cell carcinoma (SCC).

Background: Considering the significant participation of the microenvironment in the local aggressiveness of odontogenic keratocysts, this study aims to evaluate the expression of ADAMTS-1 and its substrates, versican, aggrecan and brevican in this locally invasive odontogenic cyst.
Methods: Immunohistochemistry and polymerase chain reaction (PCR) were conducted on 30 cases of odontogenic keratocysts (OKCs) and 20 dental follicles (DFs).
Results: The immunohistochemical expression of these proteins was predominantly cytoplasmic and granular across all samples.
Clinical impacts of Artocarpus lakoocha agglutinin-binding glycans for prognosis and treatment of cholangiocarcinoma.

Department of Biochemistry, Faculty of Medicine, Khon Kaen University, Khon Kaen, 40002, Thailand.
Artocarpus lakoocha agglutinin (ALA), which specifically targets the Gal/GalNAc components of complex glycans, was isolated from the seeds of Artocarpus lakoocha. This study is the first to explore the role of ALA in identifying aberrant glycans, designated ALA-binding glycans (ALAG), and its implications in cholangiocarcinoma (CCA). ALA-histochemistry was used to evaluate ALAG expression in liver fluke-induced CCA tissues from hamsters (n = 60).

A20, an ubiquitin-editing enzyme, plays a pivotal role in regulating cell signaling and immune responses. Dysregulated A20 expression has been associated with various pathological conditions, including inflammatory diseases and malignancies, where its expression levels often correlate with differing prognoses in solid tumors. This study aimed to explore the expression and cellular localization of A20 in both nonpathological and diseased human gastric tissues to gain deeper insights into its involvement in gastric pathologies.
