Primary NK/T-cell lymphoma of the larynx.

Laryngeal extranodal non-Hodgkin lymphoma is uncommon, accounting for less than 1% of all laryngeal neoplasms; the B-cell phenotype is predominant. Lymphomas outside the nasal cavity are rare and highly aggressive. We present a case of primary natural killer T-cell (NK/T-cell) lymphoma of the larynx that arose in a 45-year-old man.

Variability of neural activation during walking in humans: short heels and big calves.

People come in different shapes and sizes. In particular, calf muscle size in humans varies considerably. One possible cause for the different shapes of calf muscles is the inherent difference in neural signals sent to these muscles during walking.

TERC telomerase subunit gene copy number in different disease stages of non-hodgkin lymphoma and in hepatitis C.

ABSTRACT Focal amplification of specific regions of the genome creates high copy number and expression of oncogenes in tumors. By applying fluorescence in situ hybridization (FISH) to leukocytes of hepatitis C (HCV) patients and non-Hodgkin lymphoma (NHL) patients, we estimated gene dosage of the TERC gene at 3q26.3.

Platelet function recovery after cessation of aspirin: preliminary study of volunteers and surgical patients.

Background And Objective: Recent evidence indicates that platelet function may recover more rapidly after cessation of aspirin therapy than previously thought. The present study evaluated the effect of aspirin on platelet function using platelet aggregometry in healthy individuals and in aspirin-treated patients scheduled for surgery.

Methods: Platelet aggregation in response to arachidonic acid, epinephrine, and adenosine diphosphate was determined in 14 male volunteers during and after 10 days' aspirin administration (100 mg) and in 58 aspirin-treated patients during intake, on days 3, 4 or 6 after drug cessation, and on day 10 after drug cessation, prior to elective surgery.
