autoclave

 [aw´to-klāv]
a self-locking apparatus for the sterilization of materials by steam under pressure. The autoclave allows steam to flow around each article placed in the chamber. The vapor penetrates cloth or paper used to package the articles being sterilized. Autoclaving is one of the most effective methods for destruction of all types of microorganisms, including spores. The amount of time and degree of temperature necessary for sterilization depend on the articles to be sterilized and whether they are wrapped or left directly exposed to the steam.

(aw'tō-klāv),
1. An apparatus for sterilization by steam under pressure consisting of a strong closed boiler in which are placed a small quantity of water and a wire basket holding the articles to be sterilized.
2. To sterilize in an autoclave.
[auto- + L. clavis, a key, in the sense of self-locking]

autoclave

autoclave

A strong sealed chamber in which surgical instruments, towels, dressings, and other items can be sterilized by steam under raised pressure.

autoclave

  1. an apparatus in which objects or materials are sterilized using air-free saturated steam under pressure at temperatures in excess of 100 °C.
  2. a sealed vessel in which chemical reactions can occur at high pressure.

It was observed that casein gave maximum (1.63) PER value, which was significantly (P=0.05) higher than those of cooked, autoclaved and extruded HWMs, while minimum (1.38) PER value was observed in group fed on extruded HWM.

The NPU values of cooked (45.71), autoclaved (45.22) and extruded HWMs (40.63) were less than that of casein based diet (74.22).
Extrusion was most effective in reducing TCC as compared to cooked and autoclaved. Similarly, autoclaved significantly reduced (Pgreater than 0.05) TCC when compared to cooked meal but TCC in all samples were in safe limit.
In autoclaved soil inoculated with bacteria or fungus, more PCP degradation occurred at day 45 in fungal-inoculated treatments but it was not significantly different from bacterial-inoculated treatments by the end of the study.
Autoclaved soil treatments (treatments 4 to 6) showed increasing levels of PCP (from 2 [micro]g/g to 28 [micro]g/g) migrating into the soil up to day 135.
Combining the residual PCP in wood and soil (Table 3) indicated that reduction was higher in non-autoclaved soil amended treatments (88%) than in autoclaved soil amended treatments (40%).
Toxicity reductions, in general, mirrored the reduction of PCP (Table 4) with a significant decrease in toxicity in treatments containing soil (autoclaved or non-autoclaved) compared to treatments with no soil.
17-OHP concentrations in newborn dried blood spots collected on filter-paper cards (experiment 1a) were significantly lower after autoclaving (autoclaved 17-OHP) than before (native 17-OHP): median (25th-75th percentiles), 11.9 (5.6-21.5) nmol/L vs 18.8 (13.6-33.2) nmol/L; P = 0.001.
In experiment 2a, in which we compared 17-OHP concentrations in dried blood spots from autoclaved cards, median year-group 17-OHP concentrations were 4.6-6.3 nmol/L (Fig.
In the autoclaved cards, 17-OHP concentrations were 27.3% lower than in the native cards: median (25th-75th percentiles), 5.6 (3.6-8.9) nmol/L vs 7.7 (5.3-11.1) nmol/L; P = 0.001.
Thus, 17-OHP in dried blood spots on autoclaved or native filter-paper cards decreased 2-3% annually, and the decrease was significant on native cards but not on autoclaved cards.
