Journal ArticleDOI
Clinical utility of cytokeratins as tumor markers.
TL;DR: The clinical value of determining soluble cytokeratins protein fragments in body fluids lies in the early detection of recurrence and the fast assessment of the efficacy of therapy response in epithelial cell carcinomas.
Journal ArticleDOI

TL;DR: Recommendations are presented for the routine clinical use of serum and tissue-based markers in the diagnosis and management of patients with breast cancer and recently validated prognostic markers for lymph node-negative breast cancer patients may be of value in selecting node- negative patients that do not require adjuvant chemotherapy.
Journal ArticleDOI
Cerebrospinal cytokine levels in patients with acute depression.
TL;DR: A positive correlation was found between serum IL-1β and the severity of depression and this results indicate a unique profile for CSF proinflammatory cytokines in acute depression.
Journal ArticleDOI

TL;DR: HPRL, hyperferritinemia, hypovitaminosis D, and TPA levels did not correlate with SLE activity elevated levels of rheumatoid factor or anti‐CCP antibodies in RA, and have different immunological implications in the pathogenesis of the autoimmune diseases.
