HPO HP:0012254 Ewing sarcoma "A malignant tumor of the bone which always arises in the medullary tissue, occurring more often in cylindrical bones."

HPO HP:0012255 Dynein arm defect of respiratory motile cilia "An anomaly of the dynein arms of motile cilia. This feature is usually appreciated by electron microscopy." [HPO:probinson, PMID:19606528] The peripheral microtubules in the canonical 9 + 2 microtubular pattern of motile cilia are studded with dynein arms that contain adenosine triphosphatases and act as molecular motors to effect the sliding of the peripheral microtubular pairs relative to one another. HP:0005938

HPO HP:0012257 Absent inner dynein arms "Absence of the inner dynein arms of respiratory motile cilia, which normally are situated within the peripheral microtubules of motile cilia. This feature is usually appreciated by electron microscopy." [HPO:skoehler, PMID:19606528] HP:0200106
HPO HP:0012258 Abnormal axonemal organization of respiratory motile cilia "Abnormal arrangement of the structures of the axoneme, which is the cytoskeletal structure that forms the inner core of the motile cilium and displays a canonical 9+2 microtubular pattern of motile cilia studded with dynein arms." [HPO:probinson, PMID:19606528] Abnormal axonemal organization comprises anomalies such as an eccentric central pair of microtubuli, abnormal radial spokes and nexin links, reduced number of inner dynein arms, and displacement of the outer doublet. HP:0005938
HPO HP:0012259 Absent inner and outer dynein arms "Complete absence of the dynein arms of respiratory motile cilia, that is, absence of the inner and the outer dynein arms, which normally are situated inside and outside of the peripheral microtubules of motile cilia. This feature is usually appreciated by electron microscopy." [HPO:probinson, PMID:19606528] HP:0012256, HP:0012257
HPO HP:0012260 Abnormal central microtubular pair morphology of respiratory motile cilia "A structural anomaly of the two central microtubules of motile cilia with a 9+2 microtubuluar configuration." [HPO:probinson, PMID:19200523] The central microtubular pair is referred to as the central part of axoneme of cilium. HP:0005938
HPO HP:0012261 Abnormal respiratory motile cilium physiology "Any functional anomaly of the respiratory motile cilia." [HPO:probinson, MP:0011055] Abnormal respiratory motile cilium physiology may include alterations in ciliary beating pattern or frequency. HP:0002795
HPO HP:0012262 Abnormal ciliary motility "Any anomaly of the normal motility of motile cilia. Evaluation of ciliary beat frequency and ciliary beat pattern requires high-speed videomicroscopy of freshly obtained ciliary biopsies that are maintained in culture media under controlled conditions." [HPO:probinson, PMID:19606528, PMID:20301301] Ciliated epithelial cells bear approximately 200 motile (9 + 2) cilia that move with both intracellular and intercellular synchrony. The pattern of beat in 9 + 2 motile cilia occurs in a waveform having a forward effective stroke followed by a return stroke. The direction of stroke is a function of the directional orientation of the central microtubules. In addition to moving in synchrony, individual cilia in normal cells are very plastic and move fluidly, sometimes deforming briefly upon encountering resistance and/or particles being transported over the mucosal surface. Cilia are embedded in a watery periciliary fluid of low viscosity, which facilitates the rapid beat cycle to move the more viscous overlying layer of mucus. Ciliary beat frequency ranges from approximately 8-20 Hz under normal conditions but may be accelerated by exposure to irritants such as tobacco smoke. HP:0012261

HPO HP:0012265 Ciliary dyskinesia "A deviation from the normally well coordinated pattern of intracellular and intercellular synchrony of motile cilia. Dyskinetic cilia usually beat out of synchrony relative to neighboring cilia." [HPO:probinson, PMID:19606528] Typically, but not always, dyskinesia is characterized by markedly attenuated ciliary beat frequency. HP:0012262

HPO HP:0012272 J wave "The J wave is a positive convex deflection that occurs at the junction of the QRS complex and ST segment, the J-point." [HPO:probinson, PMID:19561994] J waves can be seen in hypothermia when the core body temperature falls below 32 degrees C. Then, they occur most prominently in the inferior leads: II, III, and aVF and the precordial leads: V5-V6. J waves can also be observed in other conditions such as some forms of Brugada syndrome.
