Periprosthetic joint infection (PJI) is one of the most challenging complications after joint replacement. However, when treated correctly, chances of recovery are good. The most important step in correct diagnosis and management of PJI is the detection of the causative germ. In the last years, the use of sonication in the diagnostic process has become more important. However, this diagnostic m...

Introduction : When treating periprosthetic joint infection with a two-stage procedure, antibiotic-impregnated spacers can be used in the interval between prosthetic removal and reimplantation. In our experience, cultures of sonicated spacers are most often negative. The objective of the study was to assess whether that sonication causes an elution of antibiotics, leading to elevated antibiotic...

Background: Mucilage is an important polysaccharide with a broad range of physicochemical properties and antioxidant activity that widely used for various applications in the medicine food industries. Objectives: This study aims to evaluate effect extraction method on mucilage extracted from yellow brown flaxseeds. Methods: was by different methods: heating, sonotrode, bath sonication. The eval...

The effect of typical membrane processing conditions on the structure, interfacial morphology, and gas separation performance of MOF/polymer nanocomposite membranes is investigated. In particular, the ZIF...

In efforts to prepare more potent and sensitive viral serological antigens, several aspects of the production of antigens from infected cell cultures were studied. Antigens derived from whole, infected culture material and from the cellular and fluid phases were compared. Freezing and thawing, sonication, and alkaline buffer extraction were compared for effectiveness in releasing antigen from h...

Purpose: To develop and evaluation ascorbyl palmitate niosomes in order to achieve a transdermal and/or systemic nanocarier of doxycycline. Methods: Vesicles were formed from ascorbyl palmitate in combination with cholesterol and a negatively charged lipid, dicetyl phosphate. Niosomes were prepared by film hydration method followed by sonication in which aqueous doxycycline solution (in phospha...

Elevated sulfate concentrations in industrial effluent can lead to a number of significant problems, the most serious of which is the corrosion of concrete sewers as a result of hydrogen sulfide induced biogenic sulfuric acid attack; hydrogen sulfide can also create odor nuisance problems. The most common treatment process for sulfate removal from wastewaters is to precipitate it as gypsum usin...

Various procedures of mixing starting powders for hot-pressing α-SiAlON ceramics were studied. They included different milling methods (attrition milling, ball milling, and sonication), liquid medium (water, isopropyl alcohol, and pyridine), and atmospheres (ambient air and nitrogen). These mixing procedures resulted in markedly different densification behavior and fired ceramics. As the powder...

For discovering the components that contributed to the bonding strength of the glue substances produced by appressoria of Pyricularia oryzae on wax-coated cover-glasses, the influences of metabolic inhibitors and hydrolytic enzymes were investigated. The bonding strength of appressoria was assessed by the ratio of the remaining appressoria after sonication to the appressoria formed before sonic...

a simple highly versatile and efficient sonochemical synthesis of 1,2,4,5-tetrasubstituted and 2,4,5-trisubstituted imidazoles is achieved by condensation of 1,2-dicarbonyl compound, aldehyde, ammonium acetate and primary amine using antimony trichloride immobilized on silica gel (sio2-osbcl2) as a catalyst in ethanol at moderate temperature. operational simplicity, practicability and applicabi...
