Chronic infection with hcv may progress to hepatic cancer.
<h3>What are chronic infections?</h3>
Chronic infection is infections which usually and frequently last for three months or longer.
They involve the presence of pathogenic virus following the primary infection and may include chronic disease. Slow infection is characterized by a prolonged incubation period followed by progressive disease.
Examples of chronic infections are as follows:
- Tuberculosis: An infectious disease of humans and animals caused by a species of mycobacterium, usually Mycobacterium tuberculosis, mainly infecting the lungs where it causes tubercles characterized by the expectoration of mucus and sputum, fever, weight loss, and chest pain, and transmitted through inhalation or ingestion of bacteria.
- Nephritis: Inflammation of the kidney.
- Cancer: A disease in which the cells of a tissue undergo uncontrolled (and often rapid) proliferation.
So therefore, chronic infection with hcv may progress to hepatic cancer. Option A

I know this is very late but the actual answer is C) Both or stage theorists
A is wrong because Piaget studied intellectual development of children and Erikson studied human development.
B is wrong because only Erikson relied on Freud's foundational work.
D is wrong because A and B are wrong.
1) Make sure the temperature is right 2) You cook it long enough. With these two factors, it can kill every bacteria in the raw meat
They are not warning the viewers about the possible effects of alcohol. They don't tell them that drinking too much is bad for your body and can cause you to pass out or even die from alcohol poisoning. Alcohol can alter your brain and cause you to make decisions that you normally wouldn't make, which can greatly affect your life.
Epithelial tissues undergo turn-over throughout adult life: cells die and are replaced. Consequently,most if not all epithelia contain stem cells that
<span>(i) are competent for cell division, </span>
<span>(ii) self renew:regeneration of a "mother" stem cell with each division, and </span>
(iii) produce differentiated cell types specific to each epithelia.
-Stem cells produce differentiated cell types by cell division coupled with specific pathways of cell specification imposed on some of their daughter cells. In most stem cell-tissue systems, cell division and specification goes through several steps. Many stem cells produce daughters that also proliferate themselves (undergo cell division cycles), often at faster rates; these transitional intermediates are called transit amplifying cells. These transit amplifying cells then produce differentiated cells, either directly or through several steps of specification. At each step,specific changes in protein expression patterns and activities occur.
-Stem cell in gland crypt bottom (tightly control stem cell, have to divide longutdinal)
<span>-Stem cell in skin basal lamina (divide in apical direction (change in phenotype) form squamous layer at apical, highly control (reactivate/reuse), secrete ligand that core signaling molecule (WINKS) in early develop than reuse and reactivate for stem cell in skin... also use in cancer cell (lost of control=tumor))</span>
