* One method was added: pressure independent control valves (PICVs).
While PICVs were not analyzed with the rigor that the other methods were in our 2002 analysis, their relative performance is included based on recent experience as well as articles such as Kent Peterson's recent Engineer's Notebook column.
In the PICV
infected hamster model, oral treatment with favipiravir suppressed deaths, reduced viral loads in the blood and tissues, and blocked the damage in the liver at 60 mg/kg/day b.i.d.
When compared with other arenaviruses, the 616-nt NP gene fragment of isolate A0070039 exhibited the highest nucleotide sequence identity and predicted amino acid sequence identity with (in decreasing order) the NP gene of WWAV prototype strain AV 9310135 (72.7% and 82.9%, respectively), TAMV (72.6% and 76.6%, respectively), the 13 South American arenaviruses (ALLV, AMAV, FLEV, GTOV, JUNV, LATV, MACV, OLVV, PARV, PICV
, PIRV, SABV, and TCRV: 55.5%-63.5% and 47.8%-62.0%, respectively), and LCMV and LASV viruses (51.5%-51.9% and 42.7%-43.4%, respectively).
Pressure independent control valves (PICVs
) entered the market almost 20 years ago, and the author has seen more designs using these valves in recent years.
Pigeon circovirus (PiCV
) infection is an emerging problem that has been reported worldwide in both young racing and meat pigeons.
HERZ is one of the major manufacturers of energy efficient products like PICVs
, DPCVs etc.
Infections with pigeon circovirus (PiCV
) occur in young racing pigeons and pigeons raised for meat production, and have been reported worldwide, but relatively little is known about the disease induced by PiCV
Comparison with other members of the Circoviridae demonstrated that RaCV shares the greatest sequence homology with canary circovirus (CaCV) and pigeon circovirus (PiCV
) and was more distantly related to the beak and feather disease virus, goose circovirus, duck circovirus, and the 2 porcine circoviruses, PCV1 and PCV2.
This paper describes a polymerase chain reaction (PCR)-based method performed on blood samples and intestinal contents to detect subclinical pigeon circovirus (PiCV
) infection in live pigeons.
An example of the impact new technology can have have on valves is found in the latest pressure independent control valves, or PICVs
. These devices combine control and balance valves into one, saving both installation time and cost.
The firm has also continued to strengthen its product portfolio with the addition of pressure independent control valves (PICVs
