Peutz-Jeghers Syndrome
|
D010580 |
[A hereditary disease caused by autosomal dominant mutations involving CHROMOSOME 19. It is characterized by the presence of INTESTINAL POLYPS, consistently in the JEJUNUM, and mucocutaneous pigmentation with MELANIN spots of the lips, buccal MUCOSA, and digits.

Pfiesteria piscicida
|
D020045 |
[A dinoflagellate with a life cycle that includes numerous flagellated, amoeboid, and encysted stages. Both the flagellated and amoeboid forms produce toxins which cause open wounds on fish. Pfiesteria piscicida feeds on tissue sloughed from these wounds, as well as on bacteria and algae. It is found in Atlantic estuaries of the United States.

Phacoemulsification
|
D018918 |
[A procedure for removal of the crystalline lens in cataract surgery in which an anterior capsulectomy is performed by means of a needle inserted through a small incision at the temporal limbus, allowing the lens contents to fall through the dilated pupil into the anterior chamber where they are broken up by the use of ultrasound and aspirated out of the eye through the incision. (Cline, et al., Dictionary of Visual Science, 4th ed & In Focus 1993;1(1):1)

Phaeohyphomycosis
|
D060446 |
[OPPORTUNISTIC INFECTIONS caused by the dematiaceous (darkly pigmented) MITOSPORIC FUNGI of ALTERNARIA, Bipolaris, CLADOSPORIUM, Curvularia, and EXOPHIALA. These fungi have pigmented HYPHAE due to MELANIN in the cell wall. The initial subcutaneous cyst from the infection can become systemic and spread rapidly to renal, pulmonary and cerebral systems (see CEREBRAL PHAEOHYPHOMYCOSIS) in an IMMUNOCOMPROMISED HOST.

Phaeophyta
|
D000459 |
[A division of predominantly marine EUKARYOTA, commonly known as brown algae, having CHROMATOPHORES containing carotenoid PIGMENTS, BIOLOGICAL. ALGINATES and phlorotannins occur widely in all major orders. They are considered the most highly evolved algae because of their well-developed multicellular organization and structural complexity.

Phage Therapy
|
D000071059 |
[Therapeutic use of BACTERIOPHAGES to treat diseases.

|
Phagocyte Bactericidal Dysfunction
|
D010585 |
[Disorders in which phagocytic cells cannot kill ingested bacteria; characterized by frequent recurring infection with formulation of granulomas.
] |
|
Phagocytes
|
D010586 |
[Cells that can carry out the process of PHAGOCYTOSIS.

|
Phagocytosis
|
D010587 |
[The engulfing and degradation of microorganisms; other cells that are dead, dying, or pathogenic; and foreign particles by phagocytic cells (PHAGOCYTES).
] |
|
Phagosomes
|
D010588 |
[Membrane-bound cytoplasmic vesicles formed by invagination of phagocytized material. They fuse with lysosomes to form phagolysosomes in which the hydrolytic enzymes of the lysosome digest the phagocytized material.

|
Phakic Intraocular Lenses
|
D054120 |
[Lenses, generally made of plastic or silicone, that are implanted into the eye in front of the natural EYE LENS, by the IRIS, to improve VISION, OCULAR. These intraocular lenses are used to supplement the natural lens instead of replacing it.

|
Phakopsora pachyrhizi
|
D000067563 |
[Fungal pathogen which causes Soybean Rust disease in Soybeans (Glycine max).

|
Phalloidine
|
D010590 |
[Very toxic polypeptide isolated mainly from AMANITA phalloides (Agaricaceae) or death cup; causes fatal liver, kidney and CNS damage in mushroom poisoning; used in the study of liver damage.

|
Phanerochaete
|
D020075 |
[A genus of fungi in the family Corticiaceae, order Stereales, that degrades lignin. The white-rot fungus Phanerochaete chrysosporium is a frequently used species in research.

|
Phantom Limb
|
D010591 |
[Perception of painful and nonpainful phantom sensations that occur following the complete or partial loss of a limb. The majority of individuals with an amputated extremity will experience the impression that the limb is still present, and in many cases, painful. (From Neurol Clin 1998 Nov;16(4):919-36; Brain 1998 Sep;121(Pt 9):1603-30)

Phantoms, Imaging
|
D019047 |
[Devices or objects in various imaging techniques used to visualize or enhance visualization by simulating conditions encountered in the procedure. Phantoms are used very often in procedures employing or measuring x-irradiation or radioactive material to evaluate performance. Phantoms often have properties similar to human tissue. Water demonstrates absorbing properties similar to normal tissue, hence water-filled phantoms are used to map radiation levels. Phantoms are used also as teaching aids to simulate real conditions with x-ray or ultrasonic machines. (From Iturralde, Dictionary and Handbook of Nuclear Medicine and Clinical Imaging, 1990)

Pharmaceutic Aids
|
D010592 |
[Substances which are of little or no therapeutic value, but are necessary in the manufacture, compounding, storage, etc., of pharmaceutical preparations or drug dosage forms. They include SOLVENTS, diluting agents, and suspending agents, and emulsifying agents. Also, ANTIOXIDANTS; PRESERVATIVES, PHARMACEUTICAL; COLORING AGENTS; FLAVORING AGENTS; VEHICLES; EXCIPIENTS; OINTMENT BASES.
