DNA-aneuploidy may reflect the malignant nature of mesenchymal proliferations and herald gross genomic instability as a mechanistic factor in tumor genesis. DNA-ploidy and -index were determined by flow cytometry in canine inflammatory or neoplastic mesenchymal tissues and related to clinico-pathological features, biological behavior and p53 gene mutational status. Half of all sarcomas were ane...

BACKGROUND Shock index [SI = the ratio of heart rate (HR) to systolic arterial pressure (SAP)] is a metric used to diagnose patients at risk of impending hemorrhagic shock. We hypothesized that a metric called the compensatory reserve index (CRI), derived using computer modeling with continuous feature extraction from arterial waveforms, would provide an earlier indicator of cardiovascular inst...

Phytases are used for feeding monogastric animals, because they hydrolyze phytic acid generating inorganic phosphate. Aspergillus niger 3-phytase A (PDB: 3K4Q) and 3-phytase B (PDB: 1QFX) were characterized using bioinformatic tools. Results showed that both enzymes have highly conserved catalytic pockets, supporting their classification as histidine acid phosphatases. 2D structures consist of ...

OBJECTIVE To evaluate the correlation between body mass index (BMI) and postural balance in unipodal support. METHOD 40 males, age 26 +/- 5 yrs, body mass 72.3 +/- 11 kg, height 176 +/_ 6 cm and BMI 23.3 +/- 3.2 kg/m(2), were submitted to functional stability tests using the Biodex Balance System (stability evaluation protocol level 2, which allows an inclination of up to 20 degrees in the ho...

Introduction: The development of repetitive central apneas during application of CPAP in patients initially showing obstructive apneas, a condition called complex sleep apnea syndrome (CompSAS), implies respiratory control instability. Respiratory control is known to be transiently destabilized by arousals. We hypothesized that PLMS and PLMrelated arousals would be more frequent in patients wit...

Falls among the older population can severely restrict their functional mobility and even cause death. Therefore, it is crucial to understand the mechanisms and conditions that cause falls, for which it is important to develop a predictive model of falls. One critical quantity for postural instability detection and prediction is the instantaneous stability of quiet upright stance based on motio...

BACKGROUND The results of open and arthroscopic instability repairs have been shown to be equivalent in recent literature. PURPOSE To compare the time to recurrence (TTR) of instability and disease-specific outcome measures in patients undergoing open and arthroscopic Bankart repair. STUDY DESIGN Cohort study; Level of evidence, 3. METHODS Patients with recurrent traumatic anterior should...

In this paper, we investigate the instability of one-dimensionally stable periodic traveling wave solutions of the generalized Korteweg-de Vries equation to long wavelength transverse perturbations in the generalized Zakharov-Kuznetsov equation in two space dimensions. By deriving appropriate asymptotic expansions of the periodic Evans function, we derive an index which yields sufficient condit...
