Alveolar Soft Parts Sarcoma Cytogenetic abnormalities of alveolar soft-part sarcomas using interphase fluorescent in situ hybridization: trisomy for chromosome 7 and monosomy for chromosomes 8 and 18 seem to be characteristic of the tumor. Alveolar soft-part sarcoma (ASPS) is a rare tumor of uncertain histogenesis, mainly localized in the extremities and less frequently found in the head, neck and trunk. Alveolar soft-part sarcoma is a rare soft tissue malignant tumor that commonly arises in skeletal muscles or musculofascial planes in children and young adults. www.thedoctorsdoctor.com /diseases/alveolarsoftparts.htm   (6748 words)

Mechanisms Associated with Human Alveolar Macrophage Stimulation by Particulates The alveolar macrophage is therefore hypothesized to play a central role in the development of particulate-induced pulmonary fibrosis (4-6) through the inappropriate release of effector molecules with bioactivity for lung cells in response to fibrogenic particulates. Alveolar macrophages from animals (7,8) and healthy human volunteers (9) exposed to fibrogenic particulates in vitro release factors that enhance fibroblast growth. Whether the release of these factors by alveolar macrophages exposed to particulates in vivo is a result of their direct interaction with the particulates, an indirect result of the interaction of the particulates with other lung cell types, or both, is not known. ehp.niehs.nih.gov /members/1994/Suppl-10/holian-full.html   (4214 words)

CDC - European Echinococcosis Registry: Human Alveolar Echinococcosis, Europe, 1982–2000 In Switzerland, where laboratory-diagnosed alveolar echinococcosis was a reportable disease until 1997, the annual incidence ranged from 7.2 to 10.4 (0.10–0.18/100,000) and did not markedly vary during a 36-year period (8). The total number of verified alveolar echinococcosis cases reported to the registry was 559; 42.0% were diagnosed in France, 23.6% in Germany, and 21.1% in Switzerland (Table 1). Death was definitely associated with alveolar echinococcosis in 13 (10.9%) of the 119 cases; in 15 cases (12.6%) death was probably related to this disease. www.cdc.gov /NCIDOD/EID/vol9no3/02-0341.htm   (4692 words)

APStracts 6:0318A, 1999.   (Site not responding. Last check: 2007-10-21) After KGF pretreatment, alveolar liquid clearance was significantly increased to 30 +/- 2%/h at 48 h, 39 +/- 2%/h at 72 h, and 36 +/- 3%/h at 120 h compared to controls (p <0.05). The increase in alveolar liquid clearance was explained primarily by the proliferation of alveolar type II cells since there was a good correlation between the number of alveolar type II cells and the increase in alveolar liquid clearance (r = 0.92, p = 0.02). The fraction of alveolar liquid clearance inhibited by amiloride was similar in control rats (33%) as in 72 h KGF pretreated rats (38%), indicating that there was probably no major change in the apical pathways for sodium uptake in the KGF pretreated rats at this time point. www.uth.tmc.edu /apstracts/1999/jap/July/318a.html   (408 words)

Chapter 4: PCO2 and Alveolar Ventilation (Part 1) Alveolar ventilation is often misunderstood as representing only the volume of air that reaches the alveoli. Physiologically, VA is the volume of alveolar air/minute that takes part in gas exchange (transfer of oxygen and carbon dioxide) with the pulmonary capillaries. Without alveolar ventilation, carbon dioxide will build up in the blood since there is no other way to eliminate it; as a result, severe acidity and death will quickly follow. www.lakesidepress.com /pulmonary/books/physiology/chap4_1.htm   (2042 words)

American Journal of Respiratory and Critical Care Medicine: Alveolar Epithelial [beta]^sub 2^-Adrenergic Receptors: ... Although Cl- channel blockade appears to have little effect on alveolar fluid clearance in normal lungs, cystic fibrosis transmembrane conductance regulator is necessary for acceleration of fluid clearance in the edematous lung (5). Alveolar fluid clearance is reduced in many models of lung injury caused by impaired function of the transport proteins discussed previously here (10-12). Isolated rat alveolar type 2 cells possess β^sub 2^-receptors, and inferential data from autoradiographic studies suggest their presence in the alveolar type 1 cells (19). www.findarticles.com /p/articles/mi_qa4085/is_200412/ai_n9466017   (1349 words)

CHEST: Increased levels of cell death and proliferation in alveolar wall cells in patients with pulmonary emphysema - ...   (Site not responding. Last check: 2007-10-21) Kasahara and colleagues (2) have shown that in the lungs of patients with emphysema, the incidence of apoptosis in alveolar wall cells is increased, in association with a decrease in the expression of endothelial survival factors such as vascular endothelial growth factor and its receptor, kinase insert domain-containing receptor. Furthermore, we have recently shown (4) that the induction of apoptosis in alveolar epithelial cells causes the loss of alveolar wall structures and emphysematous changes in mice, suggesting that apoptosis in alveolar wall cells is causally related to the development of emphysema. To maintain the pulmonary architecture, the loss of alveolar wall cells resulting from apoptosis must be offset by the proliferation of the remaining alveolar wall cells. www.findarticles.com /p/articles/mi_m0984/is_2_125/ai_113852565   (1236 words)

Articles - Alveolar consonant   (Site not responding. Last check: 2007-10-21) Alveolar consonants are articulated with the tongue against or close to the superior alveolar ridge, which is called that because it contains the alveoli (the sockets) of the superior teeth. Alveolar consonants may be articulated with the tip of the tongue (so-called apical consonants), as in English, or with the flat of the tongue just above the tip (the "blade" of the tongue; called laminal consonants), as in French and Spanish. The laminal alveolar articulation is often mistakenly called dental, because the tip of the tongue can be seen near to or touching the teeth. www.gaple.com /articles/Alveolar   (454 words)
