Water and reusable medical device surfaces can be contaminated by natural toxins such as ricin either accidentally or intentionally. This report focuses on the removal of peanut lectin (PL), a ricin surrogate, from water and reusable medical devices and materials. An ELISA assay was used to determine if commercially available water filters could remove peanut lectin from water, and if commercia...

We present a case of a 55 year-old female, who survived a complication of percutaneous closure of atrial septal defect never described before. Within the first day after treatment the device has dislodged and got stuck in the mitral valve apparatus. This has caused mitral insufficiency and massive haemolysis which resolved after interventional removal of the device.

INTRODUCTION Closed loop life support systems, such as in spacecraft or space suits, require removal of carbon dioxide and water vapor from the atmosphere. A membrane device that separates CO2 from breathing air can effectively control CO2 levels by venting the carbon dioxide directly to the vacuum of space. Such a membrane device requires no regeneration and therefore imposes no limitation on ...

Voltage boosting from CMOS photovoltaic device (PV) is achieved by implementing multiple PV units on single CMOS chip and are series connected by an external integrated passive device. Localized substrate removal process is developed to electrically isolate the PV units. Four-cell cascaded CMOS PV module provides an open-circuit voltage of 2.05 V while maintaining its superior PV performance.

We report a case in which fracture of an Amplatzer perimembranous ventricular septal defect (VSD) device occurred within 1 month after placement. This was associated with severe tricuspid regurgitation. Surgical removal of the device and repair of the tricuspid valve was performed with reasonable outcome. We propose a hypothesis on how this complication might have occurred and how it could be p...

The present study aimed to evaluate the effect of kisspeptin-10 (Kp10), a shorter variant of kisspeptin retaining full biological activity, on the release of luteinizing hormone (LH) and follicle stimulating hormone (FSH) in cyclic adult cows, and the effect of plasma progesterone (P4)concentration on the response to Kp10 administration. The experiments were performed using five postpartum cows...

Various issues pertaining to the physical construction of systems that are based on regularly interconnected device planes, such as heat removal and extensibility of the optical interconnections for larger systems, are discussed. Regularly interconnected device planes constitute a foundation architecture that is reasonably close to the best possible as defined by physical limitations. Three app...

BACKGROUND Increased menstrual bleeding and pain are the primary side effects that lead to early removal of the copper intrauterine device (IUD). Ibuprofen and other non-steroidal anti-inflammatory drugs (NSAIDs) are proven treatments for such IUD-induced problems, but their effect on early IUD removal is unknown. METHODS A total of 2019 first-time IUD users were recruited in Chile for this d...
