Characteristically, bloody droplets from the intact skin contained all blood components. Histopathologic examination showed some inconspicuous abnormal...

Infection and Anemia.

Added: Unknown

Anemia most frequently accompanies infection in varying degrees and in different forms. Anemia of inflammation is the most common and is due to over-expression of hepcidin. This is followed by hemolytic anemia, red cell aplasia and blood loss. The degree of anemia may not necessarily be proportional to the severity of the infection, nor is it specific for the type of infection. A clear understandi...

INTRODUCTION: Autologous bone graft is still considered to be the gold standard for treating non-unions in trauma and orthopedic surgery. Intramedullary bone graft harvest appears to be an alternative to other bone graft options such as iliac crest bone graft and synthetic bone substitutes. A one-step reamer-irrigator-aspirator (RIA) system has been developed to reduce the intramedullary pressure ...

Actin structure and function.

Added: 06:00 EST 15 Feb 2011

Actin is the most abundant protein in most eukaryotic cells. It is highly conserved and participates in more protein-protein interactions than any known protein. These properties, along with its ability to transition between monomeric (G-actin) and filamentous (F-actin) states under the control of nucleotide hydrolysis, ions, and a large number of actin-binding proteins, make actin a critical play...

OBJECTIVE:: The purpose of this study was to evaluate the effectiveness of bedside nursing report implementation on a pediatric neuroscience unit. BACKGROUND:: The change-of-shift nursing report often involves only nurse-to-nurse communication, occurs far away from the patient's bedside, and includes little or no patient/family involvement. Studies show that the bedside nursing report is a more co...

Shortness of breath is a common complaint in those with chronic liver disease.
