A total of 20 g methylmethacrylate (Sigma-Aldrich, stabilized with hydroquinone) each were weighed out into five 50 ml screw cap vessels. After adding 35 μl distilled water, 10 μl of a 40% ethanolic Bacillus subtilis ATCC 9357 spore suspension were added to each of the screw cap vessels. Then 34 μl (40 mg) β-propiolactone were added. The screw cap vessels were closed, shaken thoroughly for a short period of time, and stored for seven days at 23° C.

A total of 8.0 g methylmethacrylate (Sigma-Aldrich, stabilized with hydroquinone) each were weighed out into five 50 ml screw cap vessels. Then 10 μl of a 60% ethanolic Bacillus subtilis ATCC 9357 spore suspension were added to each of the plastic bottles. The preparations were then shaken briefly to homogenize the mixture. Then a mixture of 1.0 g zirconium dioxide, 5.5 g of a linear polymethylmethacrylate-co-methacrylate, and 5.5 g of a cross-linked polymethylmethacrylate was added to said preparation in each of the screw cap vessels. The preparations were then shaken briefly. A paste was thus formed. The preparations were then stored at 23° C. for seven days.

Histological Analysis of Titanium Implant Infection

Check if the same lab product or an alternative is used in the 5 most similar protocols

Immediately after harvesting the biopsies for bacteriology, we placed the infected legs containing the titanium plate and surrounding soft tissue in 70% methanol. Contact radiographs were taken using a cabinet X-ray system (Model No. 43855A, Faxitron X-Ray Corp) and high-resolution technical films (D4 Structurix DW ETE, Agfa). After fixation, samples were subjected to a dehydration process through ascending concentrations of ethanol and transferred to xylene before being embedded in methyl methacrylate (Sigma-Aldrich). Once cured, two approximately 200-µm-thick longitudinal sections were made through the plate and femur using a Leica 1600 rotating saw microtome (Leica microsystems). These sections were fixed with cyanoacrylate onto Plexiglas slides and ground to a thickness of approximately 100 μm using a microgrinding system. One section per animal was stained with Giemsa eosin.

Preparation and Characterization of Microcapsules

Check if the same lab product or an alternative is used in the 5 most similar protocols

The chemical preparation of microcapsules required the following reagents:

Shell: Methyl methacrylate (MMA) (99%, contains ≤ 30 ppm monomethyl ether hydroquinone (MEHQ) as inhibitor, Sigma Aldrich, Auckland, New Zealand) and pentaerythritol tetraacrylate (PETRA) (contains 350 ppm (MEHQ), Sigma Aldrich, Auckland, New Zealand) were used as a monomer and cross-linking agent respectively in order to obtain proper shells for MPCM.

Free radical thermal initiator: Luperox^® A75, Benzoyl peroxide (BPO) (75%, contains 25% water, Sigma Aldrich, Auckland, New Zealand) was used as free radical thermal initiator.

Surfactants: Polyvinyl alcohol (PVA) (M_w 85,000–124,000, Sigma Aldrich, Auckland, New Zealand) and sodium dodecyl sulfate (SDS) (BioXtra, 99%, Sigma Aldrich, Auckland, New Zealand) were used as a non-ionic and ionic surfactant, respectively.

PCM: a commercial paraffinic PCM, Rubitherm^® RT 21 (T_m = 21 °C, ΔH_m = 135 J·g⁻¹, Rubitherm^® Technologies GmbH, Berlin, Germany) was used.

The bulk density of M-2 microcapsules is 0.496 g·mL⁻¹. The commercial MPCM, Micronal^® DS 5008 X (BASF^®), was also selected for characterization and was compared with the microcapsules produced in this work. This sample is also composed by an acrylate shell and organic PCM in the core [13 (link)], and its bulk density is 0.445 g·mL⁻¹.

Eight weeks after implantation, the femoral specimens with different implants were placed in labeled cassettes and progressively dehydrated using an alcohol gradient (increments of 10%; range, 70–100%). The samples were then cleared in xylene, infiltrated, and embedded in methylmethacrylate (Sigma-Aldrich). Two sections of each implant were ground and polished to a final thickness of 30–50 μm in the longitudinal direction using Exakt Cutting and Grinding equipment (Exact Apparatebau, Norderstedt, Germany). The sections were mounted on clear glass or plastic for the next steps. Histological sections were stained by the methylene blue-basic fuchsine staining method. The methylene blue-basic fuchsine-stained sections of each implant were analyzed by a digitized image analysis system (Leica Imaging System, Cambridge, UK) for histometric analysis. For further analysis, the percentage of bone to implant contact (BIC) was calculated using the BIOQUANT OSTEO Bone Biology Research System (BIOQUANT Image Analysis Corporation, TN, USA) in accordance with the study design.^{32 (link)} BIC is a length ratio of the bone direct contact implant surface to the total length of the intrabony implant surface.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
