A survey study of benefits and limitations of using CellaVision DM96 for peripheral blood differentials.

In most clinical laboratories, hematologists rely on the microscopic analysis of stained blood films to accurately classify cells, aiding in the diagnosis and monitoring of a variety of disorders and conditions. Use of the microscope, although considered the gold standard in performing white blood cell differentials, presents a variety of limitations Digital image technology can facilitate a variety of essential job functions in clinical hematology such as: consulting with colleagues, improving training, referencing an abnormal cell, and utilizing archived images for quality assurance and competency assessment. A questionnaire was developed to survey medical laboratory professionals about their perceptions regarding the benefits and limitations for using digital images in clinical hematology.

Crystal structure of the Mycoplasma arthritidis-derived mitogen in apo form reveals a 3D domain-swapped dimer.

Mycoplasma arthritidis-derived mitogen (MAM) is a superantigen that can activate large fractions of T cells bearing particular Vbeta elements of T cell receptor. Here, we report the crystal structure of a MAM mutant K201A in apo form (unliganded) at 2.8-A resolutions.

Mutagenesis, biochemical, and biophysical characterization of Mycoplasma arthritidis-derived mitogen.

Mycoplasma arthritidis-derived mitogen (MAM) is a superantigen (SAg) that can activate large fractions of T cells bearing particular TCR Vbeta elements. Here we report the mutagenesis, biochemical and biophysical studies on the dimerization of MAM in solution. Our studies showed that although MAM mainly exists as a monomer in solution, a small percentage of MAM molecules form homodimer at high protein concentration, regardless of the presence of Zn2+.
