In some people, PACs occur in a predictable pattern. Two PACs in a row are called doublets and three PACs in a row are triplets. Depending whether there are one, two, or three normal (sinus) beats between each PACs, the rhythm is called atrial bigeminy, trigeminy, or quadrigeminy.
Two PVCs in a row are called doublets and three PVCs in a rows are triplets. Depending whether there are one, two, or three normal beats between each PVC, the rhythm is called bigeminy, trigeminy, or quadrigeminy. If 3 or more consecutive PVCs occur in a row it may be called ventricular tachycardia. [20]
As PACs consist of a light sensor and an enzyme in a single protein, they can be expressed in other species and cell types to manipulate cAMP levels with light. When bPAC is expressed in mouse sperm , blue light illumination speeds up the swimming of transgenic sperm cells and aids fertilization . [ 5 ]

A cell line derived from the cabbage looper is of particular interest, as it has been developed to grow fast and without the expensive serum normally needed to boost cell growth. [ 27 ] [ 28 ] The shuttle vector is called bacmid, and gene expression is under the control of a strong promoter pPolh. [ 29 ]
The transformation is usually done by electroporation, which uses electricity to allow the plasmids permeate into the cells. If high expression levels are desired, the P1 lytic replicon can be used in constructs. [5] Electroporation allows for lysogeny of PACs so that they can replicate within cells without disturbing other chromosomes. [1]
Multinucleate cells (also known as multinucleated cells or polynuclear cells) are eukaryotic cells that have more than one nucleus, i.e., multiple nuclei share one common cytoplasm. Mitosis in multinucleate cells can occur either in a coordinated, synchronous manner where all nuclei divide simultaneously or asynchronously where individual ...
Super PACs, dark money, outside spending -- keeping it all straight can be tough, especially with the seemingly constant barrage of political attack ads in the background. Holiday Spending: Get Top...
