so that the nuclei are stained during embedding and a separate nuclei staining is redundant. If a hardening mounting medium is used, which is often the case, the sample is allowed to cure overnight, so microscopic examination is possible on the following day. Permanent preparations produced in ...
Due to the small size and sometimes transparent nature of bacteria, samples may need to be cultured in advance and Gram-stained. Culturing bacteria increases the concentration of cells in a sample. To Gram-stain the culture, add either crystal violet, methylene blue or safranin to the bacterial...
The simplest way to count bacteria is called the direct microscopic cell count, which involves transferring a known volume of a culture to a calibrated slide and counting the cells under a light microscope. The calibrated slide is called a Petroff-Hausser chamber (Figure 7) and is similar to ...
(P < .03), number of passes and TBNA slides were seen.Conclusions: TBNA slides stained with Toluidine blue will give us cyto pathological diagnosis in less than 1 sec of microscopic examination which will diminish complications and helps to obtain adequate tissue rapidly in critically ill - ...
The nano-CaCO3 suspended in kerosene is referred to as kerosene suspension of nano-CaCO3 (KSNC). The rheological beha- viors and the microscopic structure of suspensions have been inves- tigated to explain the mechanisms in which the secondary fluid and nanoparticles influence the rheology of ...
Herein, we compared the developmental maturity of the cranium, limbs, and feeding apparatus in a perinatal common vampire bat relative to its mother. In addition, we introduce a method for combining two computed tomographic imaging techniques to three-dimensionally reconstruct endocasts in poorly ossi...
This form of vasculitis shows a predilection for the small intestine and proximal colon and is associated with cANCA autoantibodies, similar to microscopic polyangiitis and Wegener granulomatosis.41 Resection specimens typically show fibrinoid necrosis of vascular walls in association with intense eosinophil...
Using section methodology, Jones & Mackiewicz [1] described additional meiotic disorders such as chromo- some non-disjunctions accompanied by spindle irregu- larities, as well as bridges between spermatid nuclei in telophase II (due to lagging chromosomes), etc. One ultramicroscopic study [12] ...
Histology is used during autopsies and forensic investigations to help understand unexplained deaths. In some cases, a cause of death may be evident from microscopic tissue examination. In other cases, the microanatomy may reveal clues about the environment after death....
The Asian citrus psyllid (ACP), Diaphorina citri, is a harmful pest of citrus trees that transmits Candidatus Liberibacter spp. which causes Huanglongbing (HLB) (citrus greening disease); this is considered to be the most serious bacterial disease of cit
