Mechanisms of Treatment Failure

1993
The recently published overview of systemic treatment of patients with early breast cancer provides the best information available concerning the impact of these treatments on disease-free and overall survival [4] (reprinted in part in this volume). The modest reduction in risk of relapse achieved by these treatments may translate into major community ...

Mechanisms for Cachexia in Heart Failure

Current Heart Failure Reports, 2013
The combination of profound muscle wasting and severe weight loss that occurs in heart failure is a complex phenomenon that involves the interplay of numerous factors. In this article, we describe processes that contribute to cachexia, as part of the clinical sequelae of heart failure, and their potential underlying mechanisms.

Mechanical System Failures

2016
This chapter will review the concepts of fracture and fatigue that occupy most of part failures in mechanical system subjected to random stress (or loads). To figure out the mechanical system failures, it will benefit engineer to design the product structures—automobile, bridge, skyscrapers, and the others—in the allowable stress and strain as ...

Failure mechanisms in fibrous scaffolds

Acta Biomaterialia, 2013
Polymeric fibrous scaffolds have been considered as replacements for load-bearing soft tissues, because of their ability to mimic the microstructure of natural tissues. Poor toughness of fibrous materials results in failure, which is an issue of importance to both engineering and medical practice.

Time-To-Failure Models for Selected Failure Mechanisms in Mechanical Engineering

2010
The mechanical properties of materials are related to the fundamental bonding strengths of the constituent atoms in the solid and any bonding defects which might form. A molecular model is presented so that primary bond formation mechanisms (ionic, covalent, and metallic) can be better understood.

Illness: A mechanism for coping with failure

Social Science & Medicine (1967), 1973
Abstract Illness represents one way of coping with failure and the physician plays a unique role as the sole authority granting legitimation for the sick role. For people of limited means or incomplete knowledge of and access to other medical alternatives, the neighborhood clinic, when it is free and accessible, may serve as the major locus for ...

Mechanisms of Failure of Modular Prostheses

Clinical Orthopaedics and Related Research, 1992
The expectations of wear and longevity of total hip components are based in large part on Charnley's early work. The evolution of the total hip from the one-piece, all-polyethylene acetabular component and fixed-head femoral component to the myriad of parts that comprise many of today's total hip designs has brought with it an array of potential ...

Mechanisms of Arrhythmias in Heart Failure

Journal of Cardiovascular Electrophysiology, 1998
Mechanisms of Arrhythmias in Heart Failure. The diagnosis of heart failure infers a bad prognosis. Mortality is high and many patients die suddenly. Ventricular arrhythmias, commonly observed in patients with heart failure, are thought to underlie at least some of these sudden deaths.

Update on Mechanisms of Ultrafiltration Failure

Peritoneal Dialysis International: Journal of the International Society for Peritoneal Dialysis, 2009
Ultrafiltration failure (UFF) continues to be a major complication of peritoneal dialysis (PD), particularly long-term PD. Continuous exposure to bioincompatible PD solutions causes inflammation of the peritoneal membrane, which progressively undergoes fibrosis and angiogenesis and, ultimately, UFF.
