RESUMO

Objective: To evaluate the sterilization effect of new designed atmospheric low temperature plasma jet on Candida albicans ( C. albicans) biofilm. Methods: C. albicans was grown into the logarithmic phase, and then was added to polystyrene 24-well microtitre plate. The amount of germs were calculated by viable plate counting to determine the reproducibility of each biofilm well. The germs in biofilm were treated by plasma for different exposure time and then the survived germs were quantified by plate counting, the dead cells were determined by staining the biofilm with propidium iodide (PI), and the ultrastructural changes of the germs in biofilm were observed by transmission electron microscopy (TEM). Results: When incubated for 72 h, germs tightly polymerized and classical mature biofilm were formed. This atmospheric low temperature plasma jet could inactivate C. albicans biofilm within a short exposure time. C. albicans were 90% inactivated when treated 20 s and 55 s of plasma treatment reduced bacteria populations to undetectable levels. With the increase of treatment time, enlarged fluorescent positive area appeared, and more bacteria died with the extending of exposure. The TEM scanning results showed that the new plasma jet inactivated C. albicans biofilm mainly via disrupting cell envelopes and then leading the release of cellular components, thus resulting in loss of cell viability. Conclusion: Plasma generated from atmospheric low temperature plasma jet could damage the cell structure of C. albicans and efficiently sterilize C. albicans biofilm.

RESUMO

PURPOSE: Herein we aimed to investigate the degradation of surgical instruments in our hospital and how water quality affects the rate of metal corrosion. MATERIALS AND METHODS: We observed 279 stainless steel instruments, and determined the presence of damage like metal corrosion or scale formation. We also measured the concentrations of chloride(Cl-)and silicate(SiO44-)ions in the water used for cleaning in our operating rooms, including tap water from the city water supply and reverse-osmosis(RO)filtered water. RESULT: Pitting corrosion was observed on 71% of the instruments we investigated. The concentration of Cl- was 0.7mg/L in tap water and 0.1mg/L in RO water, while the concentration of SiO44- was 0.3mg/L in both the tap and RO water. DISCUSSION: Of the dissolved ions Cl- and SiO44-, Cl- is more of a concern, as it causes pitting corrosion over time, while SiO44- causes scale formation. Considering the typical water quality in the operating-room environment, degradation must be monitored for the general maintenance of metal surgical instruments.

RESUMO

Objective: To review the current status and progress of sterilization and preservation for allograft in anterior cruciate ligament reconstruction. Methods: The related literature about the sterilization and preservation of allografts in anterior cruciate ligament reconstruction was extensively reviewed and summarized. Results: There are many sterilization methods for allografts, the most commonly used method is γ-ray irradiation, but the optimal irradiation dose is still unclear. Electron beam irradiation is also available, but excessive dose is harmful to graft shaping. A combined sterilization method combining physics and chemistry methods is still being explored. Cryopreservation is the most commonly used method of preservation. In order to reduce the influence of crystals, the principle of "slow cooling and rapid rewarming" should be adhered to as far as possible. Conclusion: The processing methods of allograft can affect the effectiveness of anterior cruciate ligament reconstruction. The clinical doctors should consider the sterilization and preservation methods in practice.

RESUMO

Ultrasonic sterilization (US), as a promising non-thermal sterilization method, exhibits unique superiorities than traditional sterilization methods. In this study, the inactivation mechanism of E. coli O157:H7 under US was investigated in cucumber and bitter gourd vegetable juices. Results revealed that the US treatment showed good antibacterial ability in countering E. coli O157:H7. Through determinations of conductivity and ß-galactosidase activity, significant augmentation in membrane permeability of the bacteria was confirmed after the US treatment. The morphologies of the US treated E. coli O157:H7 demonstrated that the integrity of the cell membrane was disrupted by US treatment. SDS-PAGE and LSCM data further proved the disruptive action of US, leading to the leakage of proteins and DNA through the breakage on cell membrane. The decrease of metabolic-related enzyme activity was verified through investigation of bacterial metabolism. The antibacterial mechanism analysis indicated that the US can generate free radicals which resulted in the rise of intracellular oxidative stress, attenuation of energy metabolism and inhibition of hexose monophosphate pathway. As the application verification, the US treatment can cause the deprivation of E. coli O157:H7 cell viability in vegetable juices without obvious impact on the sensory quality.

RESUMO

Cranioplasty is a widely employed procedure for restoration of calvarial form and shape. The use of autogenous bone flap offers biological reconstruction with minimal donor site morbidity. One of the options to re-use bone autograft is low temperature preservation followed by autoclaving during cranioplasty. A retrospective evaluation of 12 patients with a mean age of 32.58 ±â€Š10.04 years who underwent frozen autogenous autoclaved bone cranioplasty was done. Cranial bone flaps were removed during the initial craniectomy and stored at 4°C for 20 minutes followed by preservation at -40°C in the deep freezer of the blood bank. Cranioplasty subsequently was performed at a mean time period of 172.17 ±â€Š26.20 days by thawing the bone at room temperature followed by autoclaving at 121°C under 15 psi for 40 minutes. Data regarding patients' characteristics and complications were recorded. Clinical outcomes based on skull shape and symmetry, cosmesis and scars were analyzed by a panel of 4 raters, including 3 doctors and 1 patient. Radiological outcomes were analyzed based on remaining bone thickness and bone gap widening. The present study revealed functionally, structurally, and cosmetically satisfying results. All the cases had satisfactory healing and no incidence of bone graft infection. The skull shape and symmetry, cosmesis and scars revealed excellent to moderate improvement in three-fourth of the patients. Radiological outcomes revealed none of the patients had severe resorption requiring surgical revision with excellent to good implant alignment in 92% of cases. It was concluded that frozen autogenous cranial bone flaps sterilized by autoclaving is safe and effective material for cranioplasty.

RESUMO

The main contributors to the cooked off-flavor in heat-sterilized lychee juice (HLJ) were studied by means of molecular sensory science. The HLJ which elicited cooked cabbage/potato and onion/garlic off-flavor was compared with fresh lychee juice (FLJ) having desired sensory attributes via chemical analysis and sensory evaluation. Aroma extract dilution analysis, quantitative analysis and calculation of odor activity values (OAVs) were conducted on both FLJ and HLJ. The results showed that compared with FLJ, 15 compounds had increased OAVs in HLJ, among which, dimethyl sulfide (DMS), methional, dimethyl disulfide (DMDS), dimethyl trisulfide (DMTS) and 2,4-dithiapentane presented cooked cabbage/potato, garlic/onion and sulfurous impression. The omission experiment proved that DMS, methional, DMTS, DMDS, 3-methylbutanal and 2,4-dithiapentane had significantly negative effects on the overall aroma of HLJ. Further studies on HLJs from other varieties of lychee confirmed that DMS, methional, DMTS, DMDS and 3-methylbutanal were responsible for the cooked off-flavor of HLJ in general.

RESUMO

During ohmic heating, the electric field may additionally inactivate bacterial endospores. However, the exact mechanism of action is unclear. Thus, a mechanistic study was carried out, investigating the possible target of electric fields inside the spore. Bacillus subtilis spores were heated by conventional and ohmic heating in a capillary system under almost identical thermal conditions. Wild-type (PS533) spores were used, as well as isogenic mutants lacking certain components known for their contribution to spores' heat resistance: small-acid soluble proteins (SASP) protecting DNA (PS578); the coat covering the spore (PS3328); and the spore germination enzyme SleB (FB122(+)). Treatment-dependent release of the spore core's depot of dipicolinic acid (DPA) was further evaluated. Up to 2.4 log10 additional inactivation of PS533 could be achieved by ohmic heating, compared to conventional heating. The difference varied for the mutants, with a decreasing difference indicating a decreased effect of the electric field and vice versa. In particular, mutant spores lacking SASPs showed a behavior more similar to thermal inactivation alone. The combination of heat and electric field was shown to be necessary for enhanced spore inactivation. Thus, it is hypothesized that either the heat treatment makes the spore susceptible to the electric field, or vice versa.

RESUMO

BACKGROUND: The reuse of implant healing abutments is common in dental practice. Effective elimination of bacteria and viruses is accomplished by conventional sterilization. The aim of this work was to explore the eventual survival of microorganisms on sterilized healing abutments and to rule out the presence of transmissible organic material after standard procedures. MATERIAL AND METHODS: A total of 55 healing abutments previously used in patients will be washed and sterilized in a steam autoclave at 121 C for 15 min. Each healing abutment will be cultured in Brain Heart Infusion broth (BHI) under strict aseptic conditions. Besides, two control groups will be included: one of 3 unused healing abutments, and the other of just medium. After 10 days at 37°C under a 5% CO2 100 µl of the broth will be plated on solid media (Brain Infusion Agar, BHIA) and Columbia Blood agar to test for sterility. The remaining volume will be centrifuged, the sediment fixed, and a Gram stain performed to discard the presence of non-cultivable microorganisms. Moreover, to determine the presence of remaining organic material after the cleaning and sterilizing treatments, the bioburden will be determined by measuring total organic carbon (TOC) in another 10 previously used healing abutments, cleaned and sterilized, that will be submerged in Milli-Q water and sonicated. RESULTS: No bacterial growth was detected on any of the 58 cultured abutments, indicating that the sterilization was completely satisfactory in terms of removal of live bacteria or spores. Nevertheless, significant amounts of organic carbon may still be recovered (up to 125,31 µg/abutment) after they have been sterilized. CONCLUSIONS: Significant amounts of the bioburden remained adhered to the surfaces in spite of the cleaning and sterilization procedures. Taking into account our results and data from other authors, the presence of infectious particles on the reused healing abutments such as prions cannot be ruled out.

RESUMO

Background: Ultrasonic cleaners are used for fine cleaning of medical devices, removing soil from joints, crevices, lumens, and other areas that are difficult to clean using other methods. To accomplish this fine cleaning, ultrasonic cleaners use a process known as cavitation. To understand the function of the cavitation process on items that require enhanced cleaning, a study was conducted to determine whether four commercially available products claiming to test for cavitation actually detect cavitation activity. Methods: Each of the products selected for the study were placed into a Mason jar containing cleaning solution at temperatures of 77°F (25°C) and 100°F (38°C), with no cavitation energy generated. The jars were agitated by vigorous manual shaking for five seconds (one time per minute for 15 minutes) by the same operator. The results of the commercial testing products were interpreted according to manufacturers' instructions for use and recorded following the 15-minute agitation process. Each test was repeated three times. Results: Three of the four commercially available tests claiming to detect cavitation were demonstrated to not be specific to cavitation. Each of the three tests satisfied the criteria for passing when in the absence of cavitation. Conclusion: Cavitation is an important and necessary function of all ultrasonic cleaners. The results of the study clearly demonstrate that even when no cavitation is being produced, certain tests will still provide results indicating the presence of cavitation. Those tests do not distinguish between cavitation energy and the other parameters in an ultrasonic cleaner.

RESUMO

INTRODUCTION: Steam heat sterilization could be one of the factors that affects the dimensional accuracy of surgical guides, leading to an error during guided implant surgery. OBJECTIVE: The purpose of this study was to investigate the effect of steam heat sterilization on the dimensional changes of surgical guides. MATERIALS AND METHODS: A total of 27 surgical guides, which were made by either Formlabs printer (Formlabs Inc., Somerville, MA) or Simplant (DENTSPLY Implants NV, Hasselt, Belgium), were scanned using an intraoral scanner before and after sterilization. The dimensional changes at the center of the implant sleeves were analyzed using the computer-aided design interactive software for 65 implant sites before and after steam heat sterilization at 121°C for 20 minutes. RESULTS: There was no significant difference between the mean x, y, and z axes of the center of the sleeves when measured before and after sterilization (P values were 0.37, 0.24, and 0.29, respectively). Nonparametric analysis showed no significant difference between the mean deviations of either surgical guide (P = 0.908). CONCLUSION: Steam heat sterilization has a nonsignificant effect on the dimensional changes of the tested surgical guides.

RESUMO

This study was the first to evaluate the influence of herb addition in a complex food matrix processed by microwave-assisted thermal sterilization (MATS) system for potential salt reduction implications. In a chicken pasta meal, salt concentrations included 100% (full salt) and reduced salt variations (75%, 50%, and 25% of the original salt concentration) and for each meal, a version with and without herb addition. The influence of storage time on sensory perception and acceptance was investigated, along with the odor-induced saltiness enhancement (OISE). Trained sensory panel results showed that the addition of herbs to the chicken pasta meal increased the intensity of many flavors and led to an increased saltiness perception, demonstrating their congruency with salty taste. The addition of herbs allowed for a 50% salt reduction in a processed prepared meal while maintaining the same intensity of saltiness perception as determined by a trained panel and overall meal acceptance by consumers. The OISE was only significant for the 25% salt meal (P < 0.05) suggesting that the influence of herb addition on saltiness perception at lower salt concentrations was more influential than at higher salt concentrations. Over longer storage times, meals processed by MATS and stored at ambient temperature increased in aroma, taste, and flavor intensities as well as in acceptance of many meal attributes. This study contributed an additional strategy of product reformulation, specifically herb addition, to the portfolio of salt-reduction strategies for prepared meals using MATS. PRACTICAL APPLICATION: The addition of herbs to prepared meals (chicken pasta) may allow for up to a 50% reduction in salt content while maintaining the same saltiness intensity perception and overall consumer acceptance. This has important implications for the food industry as sodium reduction is a complex task. Furthermore, the additional herbs utilized in this study increased the intensity of certain aromas and flavors, and led to increased saltiness perception; these herbs could be considered in future salt reduction applications as this study demonstrates their congruency with salty taste.

RESUMO

OBJECTIVE: To validate recommended reprocessing methods for Ipas manual vacuum aspiration (MVA) devices. METHODS: All recommended reprocessing methods for Ipas MVA devices were tested for effectiveness in cleaning, achieving high-level disinfection (HLD) and/or sterilization, and any physical effects on instruments. Worst-case scenario testing was performed using artificial soil and microorganisms. Study protocols replicated standard steps for reprocessing. The specified method for reprocessing was performed 25 times on multiple devices, including controls. After runs 1, 2, 3, 15, and 25, devices and controls were analyzed for: microbial growth; residual soils; surface damage; and functionality. RESULTS: All samples were negative for microbial growth and residual soils. On inspection and functionality testing, no damage was observed for aspirators and cannulae except with STERRAD and Cidex OPA. Other methods of HLD and sterilization did not affect surfaces or functionality through 25 cycles. DISCUSSION: Ipas MVA devices were not negatively affected following validated instrument reprocessing methods for HLD or sterilization for up to 25 reuse cycles. STERRAD and Cidex OPA did not meet assessed standards and are therefore not recommended. Strict adherence to guidance is critical for effective reprocessing of instruments.

RESUMO

AIMS: This study aims to estimate the microbial presence on the surface of different brand new NiTi endodontic instruments for clinical use. MATERIAL AND METHODS: Eleven different types of NiTi rotary endodontic instruments, obtained from their fresh opened original packages, were assigned to three different groups, according to packaging type and sterilization and tested for bacterial contamination. Isolated bacteria were identified by using standard microbiological methods and then counted. Differences observed in groups were analyzed statistically by using the one-way analysis of variance (ANOVA) for dependent samples and the Tukey HSD post hoc test. RESULTS: Statistical differences were found between instruments delivered in plastic boxes which bacterial count resulted higher than those obtained from instruments delivered in blisters (p<0.01). CONCLUSIONS: Some brand new endodontic instruments showed degrees of bacterial contamination that both quantitatively and qualitatively deserve to be considered in clinical procedures.
