Periodic mesoporous titanium phosphonate (PMTP-2) monoliths were synthesized by combining autoclaving process and evaporation-induced self-assembly strategy, which was functionalized by ClSO(3)H treatment, acting not only as an ion exchanger with large ion exchange capacity but also as a strong acid catalyst possible for some low-temperature reactions.

Active oxygen species or free radicals are considered to cause extensive oxidative damage to biological macromolecules, which brings about a variety of diseases as well as aging. The ideal scavenger for active oxygen should be 'active hydrogen'. 'Active hydrogen' can be produced in reduced water near the cathode during electrolysis of water. Reduced water exhibits high pH, low dissolved oxygen ...

With the continuous and expanding use of implantable biomaterials in a clinical setting, this study aims to elucidate the influence of sterilization techniques on the material surface and bulk properties of two polyurethane nanocomposite biomaterials. Both solid samples and porous membranes of nondegradable polyhedral oligomeric silsesquioxane poly(carbonate-urea) urethane (POSS-PCU) and a biod...

Brenes, A., Rotter, B. A., Marquardt, R. R. and Guenter, W. 1993. The nutritional value of raw, autoclaved and dehulled peas (Piszrz sativum L.) in chicken diets as affected by enzyme supplementation. Can. J. Anim. Sci. 73: 605 614. The effects ofadded crude enzyme preparations, autoclaving and dehulling on the nutritional value of diets containing a low-tannin (Trapper) and high-tannin (Maple)...

Healthcare waste (HCW) management is a complex issue influenced by many factors, including technological, economic, environmental, and social factors. It possible to regard the evaluation of best treatment technique for HCW as challenging case MCDM (multi-criteria decision-making), where various alternatives criteria must be considered. The presentation handling shaky data are crucial choosing ...

Autoclaving, the most widely available sterilization method, is applied to poly(3,4-ethylenedioxythiophene) doped with polystyrene sulfonate (PEDOT:PSS) electrophysiology devices. The process does not harm morphology or electrical properties, while it effectively kills E. coli intentionally cultured on the devices. This finding paves the way to widespread introduction of PEDOT:PSS electrophysio...

The rare complication of port-site tuberculosis following laparoscopic cholecystectomy is reported. In this case, the source of infection was most probably the laparoscope or its accessories. Thus, proper sterilization of the laparoscope and instruments is of utmost importance in preventing infectious complications and ideally autoclaving should be used for this purpose.

We report a complication of radiopaque wire breakage from the medullary tube during closed antegrade intramedullary nailing for a femoral shaft fracture. To avoid such complication, the medullary tube should be checked carefully for colour changes and surface defects, and tested for flexibility before each use. The medullary tube should also be replaced before 100 exposures to autoclaving.

We investigated Bacillus cereus-positive tracheal aspirates from infants on ventilators in a neonatal intensive care unit. Multilocus sequence typing determined a genetic match between strains isolated from samples from a case-patient and from the air flow sensor in the ventilator. Changing the sterilization method for sensors to steam autoclaving stopped transmission.
