The terminal web is a filamentous structure found at the apical surface of epithelial cells that possess microvilli. It is composed primarily of actin filaments stabilized by spectrin, which also anchors the terminal web to the apical cell membrane. The presence of myosin II and tropomyosin helps to explain the contractile ability of the ...
The most common cancer among women in the United States is breast cancer (123.7 per 100,000), followed by lung cancer (51.5 per 100,000) and colorectal cancer (33.6 per 100,000), but lung cancer surpasses breast cancer as the leading cause of cancer death among women. [13]
In the United States during 2013–2017, the age-adjusted mortality rate for all types of cancer was 189.5/100,000 for males, and 135.7/100,000 for females. [1] Below is an incomplete list of age-adjusted mortality rates for different types of cancer in the United States from the Surveillance, Epidemiology, and End Results program.
The plus ends of the actin filaments are located at the tip of the microvillus and are capped, possibly by capZ proteins, [2] while the minus ends are anchored in the terminal web composed of a complicated set of proteins including spectrin and myosin II. The space between microvilli at a cell's surface is called the intermicrovillous space.
Survival rate is a part of survival analysis. It is the proportion of people in a study or treatment group still alive at a given period of time after diagnosis. It is a method of describing prognosis in certain disease conditions, and can be used for the assessment of standards of therapy. The survival period is usually reckoned from date of ...
Katzenberger et al. graphs survival versus time for subsets of patients with varying Ki-67 indices. He shows median survival times of about one year for 61–90% Ki-67 and nearly 4 years for 5–20% Ki-67 index. [48] MCL cell types can aid in prognosis in a subjective way. Blastic is a larger cell type. Diffuse is spread through the node.

Prenatal screening in utero is currently offered by several medical centers since the gene(s) involved in the disease were recently discovered to be MYO5B; [6] [7] Diagnosis is typically made by biopsy of the small intestine.
