introduction: due to the risks of hormones on human health and aquatic life, the aims of this study were to determine the efficiency of estrogen removal in the different stages of shiraz wastewater treatment plant using activated sludge process and marvdasht wastewater treatment plant using aerated lagoons process and also comparing the performance of both systems in removing the hormone of est...

The left ventricular assist device (LVAD) is a battery-operated, mechanical pump-type device that helps in maintaining the pumping ability of a failing heart. Thromboembolism poses a significant risk during and after LVAD implantation. It occurs in up to 35% of patients with adverse sequelae. We present the case of a 75-year-old man who underwent coronary artery bypass graft surgery and LVAD im...

Introduction Cardiovascular implantable electronic device (CIED)-related infections have increased in frequency over the past 2 decades out of proportion to the rise in device implantations. This has occurred despite an improvement in technology, which includes smaller device profiles, improvement in battery life, prepectoral systems, and greater operator experience. Much of what is driving thi...

A spatial light modulator is described which consists of a row of 1200 electrostatically deflectable mirror elements. This deformable mirror device is included in an acoustooptic spectrum analyzer and, as such, allows the removal of interfering signals from 333 frequency bands. Radiometric scans demonstrate the contrast and resolution possible with the device. Based on these results, the suitab...

UNLABELLED Over recent years there has been increasing usage of digital systems within cardiothoracic surgery to quantify air leaks and aid in clinical decision-making regarding the removal of chest drains postoperatively. The literature suggests improved agreement on timing of removal of chest drains and a reduced length of stay of patients. It could be that such devices could be useful tools ...

1 BACKGROUND Implant infection and exposure are the main complications related to breast reconstructive and aesthetic surgery.1,2 In the past, treatment was immediate device removal with implant repositioning no earlier than 6 months. Recently, numerous successful attempts of device salvage have been reported.3,4 There is still disagreement about the indications and the procedures.5 We propose ...

The long-term removal of unwanted hair has become one of the most common and popular cosmetic laser treatments being performed around the world. This manuscript will review a variety of lasers and light sources that have been and are currently being used for epilation of the skin. All of the lasers and light systems currently available do work for long-term hair removal; it is the responsibilit...

Treatments of choice for cardiac implantable electronic device (CIED) infections are the removal of the entire CIED system, control of infection, and new device implantation. Occasionally, a complete CIED removal can not be performed for several reasons, such as very old age, severe comobidity, limited life expectancy, or refusal by a patient. We encountered a male patient who developed traumat...

The increased demand for minimally invasive placement of intravascular medical devices has led to increased procedure-related complications, including retention of all or part of the implanted device. A number of risk factors can predispose to unintentionally retained vascular devices (uRVD); most are technical in etiology. Despite best efforts to insert and remove vascular devices properly, uR...

Along with the increased frequency of implantation, the incidence of cardiac implantable electronic device (CIED) infection, which can have serious or fatal complications, has also increased. Although several successful conservative therapies for CIED infection have been reported, retained infected devices remain a source of relapse, which is closely related to a higher mortality rate. Presentl...
