We are describing an arthroscopy tip, which is helpful in suspected/diagnosed cases of intra-articular haemangioma of the knee. Intra-articular haemangiomas of the knee are a rare but known condition. Arthroscopy or MRI can be used for diagnosis. Arthroscopy was performed in a case of haemangioma diagnosed on MRI performed for anterior knee pain. Appearances of the haemangioma were entirely dif...

Hydrostatic pulmonary edema is a common complication of congestive heart failure, resulting in substantial morbidity and mortality. Keratinocyte growth factor (KGF) is a mitogen for type II alveolar epithelial and microvascular cells. We utilized the isolated perfused rat lung model to produce hydrostatic pulmonary edema by varying the left atrial and pulmonary capillary pressure. Pretreatment ...

Morita, Richard Y. (University of Nebraska, Lincoln) and Roger D. Haight. Malic dehydrogenase activity at 101 C under hydrostatic pressure. J. Bacteriol. 83:1341-1346. 1962.-No malic dehydrogenase activity was found to occur at 101 C at various hydrostatic pressures from 1 to 700 atm. However, activity was demonstrated with hydrostatic pressures above 700 atm, with optimal activity at 1,300 atm...

Diamond anvil cell techniques are now well established and powerful methods for measuring materials properties to very high pressure. However, high pressure resistivity measurements are challenging because the electrical contacts attached to the sample have to survive to extreme stress conditions. Until recently, experiments in a diamond anvil cell were mostly limited to non-hydrostatic or quas...

In order to compute the thermal deformation of the hydrostatic thrust bearing in the heavy type CNC equipments, a numerical research concerning temperature field of multi-pad hydrostatic thrust bearing having sector cavity, rectangular cavity, Ishaped cavity and ellipse cavity is described. Three-dimensional temperature field of gap fluid between the rotation worktable and the base has been sim...

From Raman scattering on a-plane wurtzite ZnO crystals we obtained a decreasing splitting between longitudinal and transversal optical phonons with A1 and E1 symmetry as a function of hydrostatic pressure up to 5.5 GPa. Consequently, the transverse effective charge eT exhibits a strong reduction with increasing pressure, yielding 2.17–14.6 10−3 P /GPa and 2.04–13.7 10−3 P /GPa in units of the e...

This paper presents a new methodology, apparatus design, and the experimental results of ongoing research into the measurement of the mechanical properties of musculoskeletal tissue at the cellular level. A microchamber was constructed that provides a controlled hydrostatic pressure environment for these cells where optical sectioning, via epifluorescence microscopy, was used to acquire volume ...

In a retrospective series of 37 cases of intussusception in children over 2 years of age, it was found that a subacute or chronic presentation was more common than in infancy, that few of them had rectal bleeding, and only a minority had a palpable intussusception. Diagnosis was often difficult but was helped by plain abdominal x-rays. Although the majority of children underwent surgery, with a...

Cell suspensions of three pathogens were exposed to hydrostatic pressure (HP), bacteriocin mixture (nisin and pediocin) or a combination of HP+bacteriocins and changes in colony forming units (cfu) and cell-morphology by scanning electron microscopy (SEM) were studied. Cell viability loss, as determined from the reduction in cfu before and after a treatment, occurred in Listeria monocytogenes b...
