The continuous culture of mosquitoes is a costly endeavor for vector biology laboratories. In addition to the resources that must be committed to colony maintenance, biological costs, including genetic drift and accidental colony loss, also can occur. Although alternatives do exist, their application to mosquitoes is limited. Mosquito cryopreservation remains elusive, and many important species...

background probiotics have been used for dairy products such as yogurt and yogurt drinks, however cholesterol content and lactose intolerance are important drawbacks. recently, consumption of non-dairy probiotic food especially for probiotic drink products has been intensified. objectives this research was conducted to determine the suitability of peach as a raw material for producing probiotic...

Donor heart allografts are extremely susceptible to prolonged static cold storage. Because donor treatment with low-dose dopamine improves clinical outcome after heart transplantation, we tested the hypothesis that dopamine and its lipophilic derivate, N-octanoyl dopamine (NOD), protect cardiomyocytes from cold storage injury. Neonatal rat cardiomyocytes were treated with dopamine or NOD or lef...

Adsorption cold storage has lately attracted attention for its large storage capacity and zero cold energy loss during the storing process. Thermodynamic and experimental studies on the cold storage capacity and the cold discharging process, in which the adsorber is either air cooled or adiabatic, have been presented. An adsorption cold storage system with zeolite–water working pair has been de...

The calcium, sodium, and magnesium permeability of erythrocytes from blood stored at 4 degrees C in various anticoagulant media has been studied and compared to that of fresh erythrocytes. Passive influx of CA2+ was measured at 37 degrees C in cells pretreated to abolish Ca2+ pumping and was up to fivefold greater for cold-stored erythrocytes than for fresh cells. The Ca2+ leakiness developed g...

Cold storage and reperfusion injury to transplanted kidneys contributes to increased incidence of delayed graft function and may have a negative impact on graft survival. This study examined the mechanisms by which previous heat shock protects against cell death in an in vitro model of kidney storage. Cold storage is mimicked by incubating human renal proximal tubular epithelial (HK-2) cells in...

Peach fruits subjected for long periods of cold storage are primed to develop chilling injury once fruits are shelf ripened at room temperature. Very little is known about the molecular changes occurring in fruits during cold exposure. To get some insight into this process a transcript profiling analyses was performed on fruits from a PopDG population segregating for chilling injury CI response...

We have constructed a compact purely electrostatic ion-beam trap, ConeTrap, which we have mounted inside a double-walled vacuum chamber. In the inner vacuum chamber, we can obtain ultra-high vacuum (UHV) conditions and reach thermal equilibrium at well controlled temperatures down to 10 K. The chamber was constructed partly with the purpose of making high-precision measurements in ConeTrap, but...

The objective of this study was to evaluate the storage life and quality of persimmon (Diospyros kaki Thunb.) fruit cv. ‘Karaj’ stored at 0°C for 4 months after postharvest calcium chloride treatment. Fruit weight loss, fruit firmness, total soluble solids, titratable acidity, total phenolic content, soluble tannin content, chilling injury, antioxidant activity, electrolyte leakage, and malondi...
