Transient elevation of squamous cell carcinoma antigen levels with influenza virus infection
1Department of Thoracic Surgery Chigasaki Municipal Hospital Japan.
Abstract:
We report a case of squamous cell carcinoma antigen (SCCA) elevation due to influenza B infection. A 78-year-old male had undergone right middle lobectomy and lymphadenectomy for lung squamous cell carcinoma two years and four months previously. His SCCA level ranged from 0.8 ng/mL to 1.9 ng/mL after the surgery. He underwent blood testing, including SCCA, as part of a regular check-up three days after the diagnosis of the influenza B infection. His SCCA level was 17.1 ng/mL; no recurrences were found on computed tomography. One month later, his SCCA level had decreased to 1.6 ng/mL. We should keep in mind that influenza infection may cause transient elevations in SCCA levels.

Freezing Point Depression and Boiling Point Elevation
The boiling point of a liquid is the temperature at which its vapor pressure is equal to ambient atmospheric pressure. Since the vapor pressure of a solution is lowered due to the presence of nonvolatile solutes, it stands to reason that the solution’s boiling point will subsequently be increased. Vapor pressure increases with temperature, and so a solution will require a higher temperature than will pure solvent to achieve any given vapor pressure, including one...
Antigen Presenting Cells
T cells require the help of antigen-presenting cells (APCs), which process foreign antigens into smaller fragments that can be recognized by T cells. These APCs are highly specialized cells that efficiently internalize antigens...
