Article Abstract

YKL-40 (CHI3L1) is a glycoprotein predominantly produced by reactive astrocytes in chronic active MS lesions, which are common in secondary progressive MS. In this study, YKL-40 was investigated in different stages of MS and in relation to MRI findings. YKL-40 levels in CSF samples from two independent patient cohorts of MS patients were determined with ELISA. CSF YKL-40 was increased in patients with active relapsing-remitting MS and correlated with the number of gadolinium enhancing lesions. Patients with secondary progressive MS had similar high levels of YKL-40, whereas not active relapsing-remitting MS patients had YKL-40 levels comparable to healthy controls.

Background: Early identification of pathological α-synuclein deposition (αSynD) may improve understanding of Lewy body disorder (LBD) progression and enable timely disease-modifying treatments.

Objectives: We investigated αSynD using a seed amplification assay and assessed prodromal LBD symptoms in individuals with idiopathic olfactory dysfunction (iOD).

Methods: In this cross-sectional, case-control study, we included iOD participants and normosmic healthy controls (HC) aged 55 to 75 years without diagnoses of dementia with Lewy bodies, Parkinson's disease (PD), or other major neurological disorders.

Objectives: Increasing detection of low-risk papillary thyroid carcinoma (PTC) is associated with overdiagnosis and overtreatment. N6-methyladenosine (mA)-mediated microRNA (miRNA) dysregulation plays a critical role in tumor metastasis and progression. However, the functional role of mA-miRNAs in PTC remains unclear.

Background: Cancer of unknown primary (CUP) is a challenging malignancy characterized by metastatic tumors with an unidentified primary site, even after extensive pathological and radiographic evaluation. Recent advancements in gene expression profiling and comprehensive genomic profiling (CGP) using next-generation sequencing (NGS) have enabled the identification of potential tissue origins, thereby facilitating personalized treatment strategies. Although most cases of CUP present as adenocarcinomas or poorly differentiated tumors, the treatment remains largely empirical, with limited success from molecularly tailored therapies.

Background: Ovarian cancer has the highest mortality among gynecologic malignancies. Despite cytoreductive surgery (CRS) and systemic therapy, peritoneal recurrence remains common. Hyperthermic intraperitoneal chemotherapy (HIPEC) delivers heated chemotherapy directly to the peritoneal cavity, enhancing local cytotoxicity and offering a potential therapeutic strategy.
