OBJECTIVE To review the use of quinacrine pellets for non-surgical female sterilization. BACKGROUND The transcervical insertion of quinacrine pellets has been under study for over 15 years. It could potentially expand access to sterilization services, because it is relatively simple to administer, with the use of a modified IUD inserter, and is inexpensive. METHODS Published and unpublished...

Utilizing a plasma to achieve sterilization is a possible alternative to conventional sterilization means as far as sterilization of heat-sensitive materials and innocuity of sterilizing agents are concerned. A major issue of plasma sterilization is the respective roles of ultraviolet (UV) photons and reactive species such as atomic and molecular radicals. At reduced gas pressure (≤10 torr) and...

In vitro microbial contaminations are the most serious problems in plant tissue culture. Initial attempts for micropropagation of Dionysia tapetodes, a beautiful alpine cushion plant from north-east Iran, led to 100% explants contamination. Hence, the present study was conducted to develop an efficient surface sterilization protocol for in vitro culture of field collected D. tapetodes using com...

background and objective: tubal sterilization is the most popular method of permanent female contraception, yet there is considerable debate concerning the influence of this procedure on the women’s health and menstrual pattern.   methods: we randomized 1358 women to one of the five methods of tubal sterilization; unipolar electrocauterization, bipolar electrocauterization, minilaparatomy, pome...

Sterilization of packages prior to product filling is a key step in aseptic filling machines. Chemical sterilization is one of the main conventional techniques in many packaging industries. To monitor the effect of sterilization on test microorganisms (Bacillus atrophaeus spores), an impedimetric sensor approach was developed based on a planar interdigitated electrode (IDE) design. In this work...

During the course of an investigation of cotton for use as air filters on the needles of bleeding units, a heat-resistant, spore-forming organism was isolated. Because of its unusual degree of heat resistance, the organism appeared to be more suitable as a control of the efficiency of sterilization than species of Clostridium usually employed for this purpose. Experiments were undertaken to det...

Introduction: Dental turbine chamber is a suitable reservoir for living microorganisms, so chamber sterilization is necessary for reducing cross contamination risk. On the other hand, in non-vacuum autoclaves, steam penetration into turbine chamber is doubtful, while they are still in use in dental clinics. In this study, performance of small non-vacuum autoclave in turbine chamber sterilizatio...

Background: Every year millions of dollars are expended to equip and maintain the hospital sterilization centers, and our country is not an exception of this matter. According to this, it is important to use more effective technologies and methods in health system in order to reach more effectiveness and saving in costs. This study was conducted with the aim of evaluating the technology of regi...

NON-THERMAL ATMOSPHERIC-PRESSURE PLASMA FOR STERILIZATION OF SURFACES AND BIOFILMS Johanna Ursula Neuber Old Dominion University, 2016 Director: Dr.Chunqi Jiang Bacterial resistance to antimicrobial methods is a critical issue in many fields of medicine. This work describes the studies performed to characterize and optimize the bacterial inactivation effects of a non-thermal atmospheric-pressur...

objective: despite development of new contraceptive methods, sterilization remained the most widely used method. our objective was to determine the factors contributing to decision making for tubal ligation in females. materials and methods: a cross sectional study was conducted in jinnah post graduate medical centre (jpmc) between march - november 2008. about 505 females using contraceptive me...
