determination of rt-pcr detection limit of live and dead salmonella cells in raw and sterilized milk
the objective of the current study was to evaluate the reproducibility of a reverse transcriptase pcr (rt-pcr)-based technique to differentiate viable and dead salmonella cells in raw and sterilized milk. the microorganism was initially inoculated into the milk samples followed by incubating at 37°c for 4 h prior to inactivation by heat at 80°c for 10 min. the treated and non-treated samples we...
Background and Aims: Immunohistochemical tests are one of the most important tests, which are under study to determine the prognosis of the cancers such as transitional cell carcinoma. By the time, flexible cystoscopy and urine cytology are the routine tests for following up the patients with transitional cell carcinoma, which are both operator dependent. On the other hand, cystoscopy is an inv...
PURPOSE To examine the expression of transcription factor Kruppel-like factor-6 (KLF6) in the cornea and lens of mouse eyes throughout developmental stages. METHODS C57BL/6 mice were set up for timed mating. Embryos on embryonic day (E)10.5, E12.5, E15.5, and E18.5 and eyes from mice on postnatal day (P)0, P7, P11, P15, P30, and P60 were collected for immunofluorescence staining. Transcript o...
The time required to visualize proteins using Coomassie Blue dye has been significantly reduced with the introduction of fast staining protocols based on staining with a Coomassie Blue dye solution at boiling temperatures. However, fast stainings suffer from high gel backgrounds, reducing the signal-to-noise ratio and limiting the number of detectable spots in the case of 2D SDS-PAGE. The aim o...
BACKGROUND In Duchenne muscular dystrophy (DMD), previous freeze-fracture electron microscopic studies demonstrated that muscle plasma membrane contained markedly decreased numbers of orthogonal arrays. Recent investigations showed that orthogonal arrays were composed of aquaporin 4 (AQP4) molecules, a member of the water channel protein family. OBJECTIVES To study whether the immunostainabil...
PURPOSE To investigate the presence of epithelial sodium channels (ENaC) in rabbit and human conjunctival epithelium and to test the effects of topical amiloride, a potassium-sparing diuretic that blocks the ENaC, on tear quantity in rabbits. METHODS Both healthy normal human and rabbit conjunctival tissues underwent immunohistochemistry staining for ENaC-α and γ subunits as well as for rever...
