Histologic examination of colonic biopsy samples showed mild, chronic, interstitial inflammation, including eosinophils and lymphoid microaggregates.
According to Tisdall and Oades (1982), inorganic and relatively persistent organic binding agents are important to the development of microaggregates, whereas physical entanglement of the hyphae of microorganisms and roots which are labile or subject to rapid decomposition the major mechanisms in binding microaggregates into macroaggregates.
The microspheres size is poorly uniform, and some irregularly shaped multiparticle microaggregates can even be observed.
Abstract: Blood filters that prevent clots, microaggregates, and other debris from being passed from the donor blood into the recipient are an essential component of blood transfusions in mammalian species but have not been consistently recommended in avian transfusions.
McCarthy JF, Ilavsky J, Jastrow JD, Mayer LM, Perfect E, Zhuang J (2008) Protection of organic carbon in soil microaggregates via restructuring of aggregate porosity and filling of pores with accumulating organic matter.
She speculated that circulatory shunting of unfiltered microaggregates and vasoactive chemicals to the cerebral vasculature may occur with right-to-left shunting and produce recurrent transient ischemia, theoretically increasing the risk of cognitive dysfunction.
The accumulation of humus was accompanied with the formation of new crumble and granulous macro- and microaggregates, as well as with the decrease in bulk density of the topsoil (Table 4), as a consequence of which an upward growth of the humus profile took place (Reintam 1997).
Primary aggregation involves shape change with formation of microaggregates, both reversible.
Following NSTEMI, between 60 to 85% of cases demonstrate a patent infarct-related artery, (6,7) yet patients develop symptoms of myocardial ischemia and signs of myocardial necrosis, which reflect the importance not only of epicardial coronary artery occlusion/stenosis in the pathophysiology of acute myocardial ischemia, but also the importance of distal embolization of platelet-rich microaggregates of thrombus, with attendant 'micro-infarction' and independent effects on outcomes, regardless of flow in the epicardial artery.
RPE microaggregates were then plated on BCE-ECM [28] or ECM ligand-coated cultured dishes/wells.
In surface horizons, aggregates are frequently subdivided into microaggregates (less than 250 [micro]m) and macroaggregates (greater than 250 [micro]m), with the tacit assumption that macroaggregates are composed of microaggregate assemblages.
Therefore, these inhibitors minimized platelet activation during venipuncture and during their isolation and prevented the formation of microaggregates that could have been lost during the centrifugation steps.
