purpose: to image leukocyte adherence to the vascular endothelium and extravasation into surrounding tissues in neovascularized corneas using acridine orange, a selective dna stain, in rats methods: corneal neovascularization was induced by placing two sutures in the cornea of one eye of 12 long-evans rats. one week later, acridine orange (4 mg/kg) was injected via the tail vein and the eyes we...

introduction: skeletal staining is an important part of anatomical studies which can evaluate macroscopic disorders in bones and cartilages development. the aim of the present article is to illustrate two distinct protocols by all details in order to stain skeletal system of the lab animals in all ages of their lives so it becomes easy for future studies in this field. methods: in this paper, s...

introduction: unstained formalin-fixed whole brain specimens and brain slices do not give satisfactory results for teaching neuroanatomy. in addition, difficulties in obtaining human brains for dissection have increased the demand for more durable brain specimens that have been obtained by the plastination technique. in the present study brain specimens were sliced, fixed and stained using the ...

Multidrug-resistant Enterococci colonizing the intestinal tract of patients are major sources infection as well spread resistance. The present study aims to determine antimicrobial resistance profile Enterococcus species from admitted laboratory Yaounde Military Hospital. was conducted in July November 2020. Stool samples were collected and processed for bacterial isolation susceptibility testi...

Sections of hypocotyls, roots and leaves from Pentalinon andrieuxii plantlets were transiently transformed with Agrobacterium tumefaciens LBA4404 bearing the binary plasmid pCAMBIA2301 with an interrupted β-glucuronidase (GUS) gene. Histochemical GUS assays showed transient gene expression in all infected tissues, being older roots those which displayed the most intense GUS staining. To our kno...

Aim: To compare the effect of four different polishing systems on color stability of two Nano composite resins immersed in four beverages (Coffee, Tea, Cola and Fanta). Methods: Eighty disc shaped specimens of 10 mm diameter and 2 mm thickness were prepared for each of the two Nano composite resins (Tetric N Ceram; Estelite alpha). The specimens of each material were divided into four groups (n...

The aim of this in vitro study was to evaluate and compare the color stability of different esthetic restorative materials (one microfilled composite, one nanofilled composite, one nanoceramic composite, one microfilled hybrid composite, one microfilled hybrid composite, one nanohybrid Ormocer based composite and one supra-nano spherical hybrid composite) after exposure to different staining so...

Methods This prospective study was done at NMC, Nellore from July 2008-December 2009. Samples received at microbiology lab for acid fast staining were included in this study. Smears were stained by Ziehl-Neelsen’s technique. Samples were cultured on Lowenstein-Jensen media after processing by modified Petroff’s method and incubated according to CLSI guidelines. Identification of Mycobaterium tu...
