CRISPR/Cas9 system is a powerful gene editing tool in vivo and in vitro. Currently, CRISPR/Cas9 delivery cells or tissue with different vehicles are available, and Adeno- associated virus (AAV) in one of them. Due to AAV packaging size limitation, AAV base vectors that carry CRISPR/Cas9 system do not have florescent tag like GFP for simple detection and navigation of cells, containing AAV. The ...

The standard diagnostic test for differentiating staphylococci from micrococci is based on the ability of the former to produce acid anaerobically in a glucose-containing growth medium. This test has been modified to provide greater convenience, easier interpretation of results, and better correlation with deoxyribonucleic acid (DNA) base composition. In the modified test, shake cultures in Bre...

Diamond's medium modified, the commercially available version of the Klaas modification of Diamond's medium, was compared to Kupferberg medium and to direct wet-mount examination for detection of trichomonads in symptomatic patients. Diamond's medium was found to be superior to both Kupferberg medium (P less than 10(-4) and wet mount (P less than 10(-6].

Cultured plant cells are often highly heterogeneous in terms of secondary metabolite production. We have developed a quantitative determination method that uses an image processing system to estimate such individual cell characteristics as content of the secondary metabolite, anthocyanin. In this study, strawberry cells producing anthocyanins were grown in modified Linsmaier-Skoog medium. Antho...

A sugar fermentation medium for the confirmation of Neisseria and related species was developed. The medium contained a commercial supplement and a hemoglobin source prepared from lysed sheep erythrocytes. Bicarbonate in the medium substituted for a CO2-supplemented atmosphere. The medium was dispensed into screw-capped tubes. This medium was compared to cystine-Trypticase agar and the modified...

A cationic 7-aminomethyl-7-deaza-2'-deoxyguanosine (7amG) was incorporated site-specifically into the self-complementary duplex d(G¹A²G³A⁴X⁵C⁶G⁷C⁸T⁹C¹⁰T¹¹C¹²)₂ (X = 7amG). This construct placed two positively charged amines adjacent to the major groove edges of two symmetry-related guanines, providing a model for probing how cation binding in the major groove modulates the structure and stabili...

one of the important methods of plant propagation in large scale so as genetic manipulation and artificial seed production is somatic embryogenesis technique. the obtained results from this methods related to different factors including condition of culture medium. therefore, the aim of this study conduction were determining the role of molybdenum during carrot petiole somatic embryogenesis. at...

The gimbal stabilization mechanism is used to provide the stability to an object mounted on the gimbal by isolating it from the base angular motion and vibration. The purpose of this paper is to present a model of control servo system for one axis gimbal mechanism using a cascade PID controller. The gimbal torque relationships are derived by taking into consideration the base angular motion. Th...
