Squash preparation of stained onion root tip cells showing various stages of mitosis. Differential interference contrast optics on a Leica microscope, Image taken with the X40 objective lens.  Depth of focus is extremely shallow (just a few microns).  Differential interference contrast results in an optical slice horizontally through the specimen providing maximum possible resolution at this magnification and good contrast. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Cirrhosis is a complication of liver disease which involves loss of liver cells and irreversible scarring of the liver. Typically, the disease comes on slowly over months or years. Early on, there are often no symptoms.  As the disease worsens, a person may become tired, weak, itchy, have swelling in the lower legs, develop yellow skin, bruise easily, have fluid build up in the abdomen, or develop spider-like blood vessels on the skin. Cirrhosis is most commonly caused by alcohol, hepatitis B, hepatitis C, and non-alcoholic fatty liver disease. Non-alcoholic fatty liver disease is due to a number of reasons, including being overweight, diabetes, high blood fats, and high blood pressure.  Cirrhosis is characterized by the replacement of normal liver tissue by scar tissue. These changes lead to loss of liver function. Diagnosis is based on blood testing, medical imaging, and liver biopsy.  Image illustrates hepatic steatosis and chronic hepatitis.  Trichrome stain

Blastomycosis is a fungal infection caused by inhaling Blastomyces dermatitidis spores. If it involves only the lungs, it is called pulmonary blastomycosis. Only about half of people with the disease have symptoms, which can include fever, cough, night sweats, muscle pains, weight loss, chest pain, and feeling tired.
