AbstractOf all the oral sensations that are experienced, “metallic” is one that is rarely reported in healthy participants. So why, then, do chemotherapy patients so frequently report that “metallic” sensations overpower and interfere with their enjoyment of food and drink? This side-effect of chemotherapy—often referred to (e.g., by patients) as “metal mouth”—can adversely affect their appetite, resulting in weight loss, which potentially endangers (or at the very least slows) their recovery. The...

Abstract Alzheimer’s disease has become a public health priority, so an investigation of new therapies is required. Tacrine (TAC) was licensed for treatments; however, its oral administration caused hepatotoxicity, so it is essential to reduce the side effects. PAMAM dendrimer generation 4.0 and 4.5 (DG4.0 and DG4.5) can be used as drug delivery systems and as nanodrugs per se. Our work aims to propose a combined therapy based on TAC and PAMAM dendrimer co-administration. TAC...

In this paper, a new method without any tradition assumption to estimate the utility harmonic impedance of a point of common coupling (PCC) is proposed. But, the existing estimation methods usually are built on some assumptions, such as, the background harmonic is stable and small, the harmonic impedance of the customer side is much larger than that of utility side, and the harmonic sources of both sides are independent. However these assumptions are unpractical to modern power grid, which causes...
