Case Presentation:
A 40-year-old male subject employed as a grocery store manager presented to a pulmonary clinic with a dry cough and progressive dyspnea of 1 year duration. The patient was previously an avid cyclist and first noted his dyspnea when he was unable to bike as far as before. Bilateral interstitial lung infiltrates were recently noted on chest radiography. At the time of presentation, he could no longer cycle due to dyspnea. The patient's medical history was significant for albinism and severe visual impairment. He had no family history of albinism or pulmonary disorders. He had never smoked, drank alcohol only occasionally, and had no significant environmental exposures.

Tumor Progression
Colon cancer is one of the best-documented examples of tumor progression. Early mutation in the APC gene in colon cells causes a small growth on the colon wall called a polyp. With time, this polyp grows into a benign, pre-cancerous tumor. Further...

Voltaic/Galvanic Cells
Spontaneous redox reactions occur abundantly in nature. The chemical reaction occurring in a disposable AA battery powering our remote controls is one such example of a spontaneous redox reaction. Another example is the immersion of coiled copper wire into an aqueous silver nitrate solution. The reaction shows a gradual, visually impressive color change from colorless to bright blue and the formation of a grey precipitate on the copper wire. In this experiment,...
