Perilous refers to something that is very dangerous or hazardous; threatening to harm or cause harm.
Perilous
Péricolonic refers to the tissues that surround the colon, a part of the large intestine. The term "pericolonic" is often used in medical contexts to describe inflammation or diseases that affect these tissues, such as pericolonic inflammatory bowel disease.
A colostomy is a surgical opening made in the large intestine (colon) and attached to the abdominal wall, allowing waste to exit the body. A pericolostomy is a type of colostomy that is performed in patients with peritonitis, which is an inflammation of the lining of the abdominal cavity. The procedure involves creating an opening in the colon and suturing it to the abdominal wall, allowing the patient to pass stool through the stoma.
Periconceptional refers to the period of time just before and immediately after conception, typically spanning from a few weeks to a few months before pregnancy and extending into the early weeks of gestation. This period is crucial for fetal development and is often targeted in research and clinical practices aimed at improving pregnancy outcomes, such as preconception care and nutrition.
A pericope is a section or passage of a text, especially the Bible, that is marked by a quotation, a change of speaker, or a shift in scene.
Pericoronitis is a bacterial infection that occurs at the junction of the gum and the tooth, typically surrounding a partially erupted tooth, such as wisdom teeth.
The word "pericranial" refers to something that is related to or surrounding the skull or cranium. Specifically, it can refer to tissues or structures that surround or extend from the skull, such as the pericranial fascia, which is a layer of connective tissue that surrounds the brain and skull.
The pericranium is the external layer of the skull, including the scalp and the bony and cartilaginous structures that cover the cranium. It is a loose, fibro-fatty layer that adheres to the inner surface of the skull, separating it from the underlying tissue.
Periculum is a Latin word that means "danger" or "risk". It is often used in combination with other words to convey a sense of danger or hazard, such as "periculum vaccinale" which means "the risk of vaccination". In a more formal or technical context, it can also refer to the risk or hazard involved in a particular situation or activity, such as "periculum in mora" which means "the risk of delay" or "the danger of being delayed".
Pericyazine is a medication primarily used to treat symptoms of schizophrenia, a mental disorder characterized by impaired cognition, delusions, and disorganized behavior. It belongs to the phenothiazine class of antipsychotic medications. It is also used off-label to treat anxiety, insomnia, and restlessness. Pericyazine works by altering the levels of certain neurotransmitters in the brain, such as dopamine and serotonin, to reduce symptoms of psychosis. It is available in oral and injectable forms and is typically prescribed in combination with other medications or therapies.
Pericycle refers to the inner layer of the stem or root of a plant, located between the phloem and the xylem. It is a type of ground tissue that plays a role in transporting nutrients and hormones within the plant.
Pericyclic refers to a type of organic reaction in which a ring is formed or expanded by a sequence of cyclic movements of atoms or groups of atoms within a molecule, rather than through the addition of new parts or the elimination of parts. These reactions typically involve a continuous path of bonding and antibonding interactions, which can result in a stable product. Pericyclic reactions are an important class of organic reactions that are often used in synthetic chemistry to create complex molecules.
Pericystitis is a rare and serious medical condition characterized by inflammation of the connective tissue surrounding a cyst, usually a kidney calculus. The term "pericystitis" comes from the Greek words "peri," meaning "around," and "kystis," meaning "cyst."
Pericytes are a type of cell that surrounds blood vessels, particularly capillaries and post-capillary venules. They are a key component of the blood-brain barrier and play a crucial role in maintaining the integrity of the vessel wall and regulating blood flow. Pericytes also have been implicated in the pathogenesis of various diseases, including cancer, atherosclerosis, and neurological disorders.
Pericytes are a type of cell found in the walls of blood vessels, particularly in capillaries and venules. They are perivascular cells that help to support the surrounding endothelial cells and smooth muscle cells that form the blood vessel wall. Pericytes play a crucial role in maintaining blood vessel integrity and facilitating the exchange of nutrients and waste products between the blood vessels and surrounding tissues. They can also help to regulate blood flow by contracting or relaxing their walls to adjust blood vessel diameter. In addition, pericytes have been found to have a role in the development and progression of various diseases, including angiogenesis, inflammation, and cancer.
A peridectomy is a medical procedure in which the diseased or damaged peridental membrane surrounding a tooth is removed. The peridental membrane is a layer of soft tissue surrounding the tooth that can become inflamed or infected, leading to conditions such as periodontitis.
