Establishment of an efficient explants surface disinfection protocol is essential for in vitro cell and tissue culture as well as germplasm conservation, such as the case of Grapevine (Vitis spp.) culture. In this research, different procedures for disinfection and regeneration of field-grown grapevine cv. 'Flame seedless' axillary buds were evaluated. The buds were disinfected using either NaO...

Because micro-organisms play a crucial role in the development of pulpal and periapical disease, the prognosis of endodontic therapy is intimately related to the presence of bacteria within the root canal system. Micro-organisms may persist in the apical region of the root canal system despite chemomechanical preparation. The usefulness of Class IV lasers (such as Nd:YAG, diode, KTP and Er:YAG)...

Micro-endodontics has emerged as a critical component in endodontics, revolutionizing the management of complex root canal anatomy. It utilizes magnification devices, such dental operating microscopes or loupes, to enhance visualization and identify intricate anatomical details. encompasses advanced techniques technologies that are utilized alongside principles conventional endodontics. While b...

A cheap method by which hospital blankets may be effectively disinfected (approximately 3d. per blanket) is described. A recommendation is made that blankets from the patients' beds be divided into: ;socially dirty' blankets to be laundered, possibly at infrequent intervals; and ;socially clean' blankets to be disinfected frequently. The wide range of a synthetic phenolic compound is described....

Outflows from secondary stages of conventional mechanical-biological wastewater treatment plants (WWTPs) still contain significant concentrations faecal pollution indicators suggesting the potential presence pathogenic organisms. The decrease in concentration somatic coliphages and bacterial during technological (coagulation, sand filtration, membrane ultrafiltration, sorption on granular activ...

BACKGROUND: The current standards for chlorine and monochloramine disinfection of drinking water were established using information obtained from bench-scale disinfection experiments of monodispersed hepatitis A virus. It is not clear whether these standards are sufficient for the four virus types listed on the CCL2. Several disinfection studies have been conducted on representative coxsackievi...

Ultraviolet light (UV) is a recognized disinfection alternative to chlorine and ozone in many applications from drinking water to wastewater treatment. UV provides effective disinfection without production of problematic disinfection byproducts. Information on the mechanism and application of UV for drinking water disinfection is presented. Advantages and disadvantages of the technique are disc...

This study evaluated the effect of disinfection methods [chemical disinfection (immersion in 100 ppm chloride solution) or microwave disinfection (690 W for 6 min)] on the internal adaptation of denture bases and resin surface roughness. For the adaptation test, 18 maxillary denture bases were obtained from stone casts duplicated from a metallic master model and submitted to the following treat...
