Breast cancer, a leading cause of mortality among women, has been recognized as requiring improved diagnostic methods. Exosome proteins, found in small extracellular vesicles, have emerged as a promising solution, reflecting the state of their cell of origin and playing key roles in cancer progression. This review examines their potential in breast cancer diagnosis, discussing advanced isolation and characterization techniques such as ultracentrifugation and microfluidic-based approaches.

Evans syndrome is a rare autoimmune disorder characterized by autoimmune hemolytic anemia (AIHA) and immune thrombocytopenia (ITP), often linked with systemic lupus erythematosus (SLE). We present a case of a 25-year-old female with a history of rheumatoid arthritis (RA) who presented with new SLE symptoms, including left-sided weakness, pallor, and a photosensitive rash. Laboratory tests confirmed Evans syndrome, and MRI showed a cerebral infarction.

Background: Crohn's disease is a chronic, relapsing form of inflammatory bowel disease marked by severe gastrointestinal inflammation and a broad range of debilitating symptoms. Despite advances in medical treatments, achieving sustained remission remains challenging for many patients. This umbrella review aims to consolidate evidence from various systematic reviews to evaluate the efficacy and safety of stem cell therapies in treating Crohn's disease.

Article Synopsis
  • The study introduces a new sensor made from a combination of zinc oxide and cobalt oxide (ZnO/CoO) designed for detecting levodopa, a medication used for Parkinson's disease.
  • This sensor, modified with a specific type of screen-printed electrode, shows clear and enhanced signals for levodopa in a phosphate buffer solution at a pH of 6.0, making it effective for measurements.
  • Using a technique called differential pulse voltammetry, the sensor demonstrated a wide detection range (0.001-800.0 μM) and a very low limit of detection (0.81 nM), while also being unaffected by the presence of other substances, indicating high selectivity in real sample analysis.
