$The Raf/MEK/ERK (MAPK) propagates growth signals in the cell. Misregulation can lead to cancer.\nThe red dots on the active EGFR are phosphorylated tyrosines. PDB entries: 1egf, 1nql, 1m17, 2jwa, 3njp, 2gs6, 1gri, 1xd2, 3ksy, 5p21, 6xi7, 6q0j, 2y4i,$

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.

Squash preparation of onion root tip cells stained to reveal chromosomes, Bright field illumination, light microscopy. This image was taken with the X40 objective lens. Depth of focus is extremely low at this magnification. Smaller apertures give greater depth of focus, but image quality deteriorates and resolution is greatly reduced. The aperture in this image was optimised for contrast and resolution. Chromatic abberation is inevitable in light microscopy, but has been kept to a minimum in this image.

Photomicrograph of two rotifers. Rapidly rotating cilia at top of heads, internal organs visible. Live specimen. Wet mount, 10X objective, transmitted brightfield illumination.

Epidermis. Electron microscope micrograph showing a keratinocyte of spinous layer. The epithelial cell has a polygonal shape, central nucleus with nucleolus, cytoplasm full of keratin filament bundles, and numerous dark desmosomes crossing the intercellular spaces.

Different types in cell development glass dishes on desk. Group of Petri dishes with different culture media and micro organisms grown.

Epidermal growth factor (EGF) activates the EGF receptor (EGFR), that dimerizes. Red dots are phosphorylated tyrosines. The signal transduction continues through GRB2/SOS, Ras, Raf/MEK and ERK, that will activate many processes in the cell.

Bone marrow plasma cells .Plasma cell neoplasms are diseases in which the body makes too many plasma cells. Plasma cell neoplasms can be benign or malignant. Diagnosed with Immunostain CD138 positive.
