"We found that in the coastal waters off of Delaware, Alabama, and Hawaii, there are a number of naturally occurring Vibrio predatory bacteria (VPB)," says Richards.
Richards's idea is to take advantage of VPB's abilities to serve as Vibrio predators in seawater by introducing the bacteria into a shellfish industry process known as depuration.
Pretreatment with VPB, phages, or both may allow shellfish to pick up these beneficial bacteria or viruses during the normal commercial filtering processes where they could disinfect vibrios from within the edible shellfish tissues, according to Richards.
No statistically significant difference was found both between all patients and the control group (p>0.05) and between the patient subgroups divided by ventricular arrhythmias and the controls who had no VPBs in terms of heart rate variability measurements (Table 3).
(33) in which 24-hour Holter monitoring was performed in 360 healthy children, VPBs were found in 18% of newborns, in 6% of infants, in 8% of children aged between 4 and 6 years, in 14% of children aged between 9 and 12 years and in 27% of children aged between 13 and 15 years.
In addition, no significant difference was found between the three patient groups divided by the number of VPBs on 24-hour Holter monitoring and presence of complex ventricular arrhythymias and the control group.
One design consideration is the gain split between the SSA and VPB. Initially, MPMs were developed with a 50/50 gain split between these two components.
The projected reliability of the MPM is based on the projected reliability of the VPB, the SSA and the EPC.
Sensitivity to arrhythmia was measured as the threshold dose of aconitine required to produce VPBs, VT, and VF, calculated as 10 [micro]g/mL x 0.2 mL/min x time required for inducing arrhythmia (minutes)/ body weight (kilograms).
During aconitine infusion, the first arrhythmia to manifest was the VPB; continued infusion of aconitine then elicited three or more successive VPBs or VT, and then VF.
While determining HRT, abnormal beats and areas of artifact, which were accepted as VPB by computer, were manually identified and excluded.
Turbulence slope (TS) is a measure of the rate of sinus deceleration that follows the sinus acceleration after a VPB. It is accepted as the maximal positive slope among all slopes of a series of regression lines obtained from all sequences of five consecutive RR intervals (within the first 20 sinus rhythm intervals after a VPB), and expressed as ms/RR.
