To determine whether single motor units (MUs) in multitendoned muscles distribute tension to multiple tendons or instead focus tension selectively on a single tendon, we examined the distribution of tension generated by single MUs in the cat extensor digitorum lateralis (EDLat), and in its macaque homolog, the extensor digiti quarti et quinti (ED45).(More)
1. Isotonic shortening of cat superficial lumbrical muscles was studied during maximal tetanic contractions of single motor units of identified types. For each motor unit, the maximal speed of contraction, Vmax, was determined by extrapolating to zero the hyperbolic relation between applied tension and speed of shortening. 2. The maximal speeds of(More)
Hydrophobic silica nanopowder has been used as an effective latent fingermark development agent and subsequently as an enhancement agent in the surface-assisted laser desorption/ionisation-time of flight (SALDI-TOF) mass spectrometry for analysis of fingermark components. The technique has been used in the detection of nicotine and cotinine in the(More)
Patients with migraine headaches are commonly encountered by clinicians both in the clinic and in the emergency department. Migraines impose a significant financial burden on patients, caregivers, and society. Up to 49% of patients treated acutely for migraine headache will have a recurrence within 72 hours. Recurrence of migraines is dependent on a number(More)
BACKGROUND Data on long-term outcomes of elderly (≥65 years) patients in ICU are sparse. MATERIALS AND METHODS Adult patients (n = 1563, 45.4% elderly) admitted over 28 months were analyzed by competing risks regression model to determine independent factors related to in-hospital and long-term mortality. RESULTS 414 (26.5%) and 337 (21.6%) patients(More)
BACKGROUND Increased heart rate has shown to be associated with adverse cardiovascular outcomes. This aim of this study was to find the association of troponin level and ejection fraction (EF) with triage heart rate in patients with non-ST elevation myocardial infarction (NSTEMI). It was hypothesized that heart rate at triage will be independently(More)
A 52-year-old African American man with untreated AIDS and active intravenous drug abuse presented with a three-day history of bilateral upper abdominal pain radiating to the back, which was associated with loss of appetite and generalized weakness. There was no fever or night sweats, and no vomiting, diarrhea, dysuria or hematuria. He denied cough,(More)
