We introduce and analyze an exterior-point method (epm) for constrained optimization problems with both inequality constraints and equations. We show that under the standard second-order optimality conditions the epm converges to the primal-dual solution with 1.5-Q-superlinear rate.

Background: Medicinal plants with natural antioxidants have been shown to be beneficial in a variety of complications such as anxiety. The elevated plus-maze (EPM) is one of the most widely used models to assess anxiety in small rodents. Objectives: This study was designed to characterize the anxiolytic-like activity of Borago officinalis (Linnaeus, family Boraginaceae) or Borage flowers extrac...

The elevated plus-maze (EPM) is currently used to study the neural basis of anxiety as well as to assess the anxietymodulating activity of various pharmacological agents. Although the anxiogenic stimulus is supposed to be the open space in this test, the anxiety-related behavioral baseline of rats is sensitive to numerous methodological-linked parameters [1]. In order to improve the quality of ...

The antiproliferative activity of the aspirin derivative [2-acetoxy-(2-propynyl)benzoate]hexacarbonyldicobalt (Co-ASS) and its analogue hexacarbonyl[μ-(2-ethylphenyl)methanol]dicobalt (Co-EPM) was investigated on malignant pleural mesothelioma (MPM) cell lines, having an epithelioid or a sarcomatoid phenotype. In sarcomatoid cell lines Co-ASS was more potent than Co-EPM and the prototypal metal...

Rat bone marrow (BM) small cells were enriched by velocity sedimentation, further separated by means of free-flow electrophoresis, and characterized using Tand B-cell-specific surface markers. More than 80% of these cells were small lymphocytes by morphological criteria and reacted with lymphocyte-specific antisera. A minority of cells had high electrophoretic mobility (EPM), carried surface an...

Equine protozoal myeloencephalitis (EPM) is a neurologic syndrome seen in horses from the Americas and is mainly caused by Sarcocystis neurona. Recently, a 29-kDa surface antigen from S. neurona merozoites was identified as being highly immunodominant on a Western blot. This antigen has been sequenced and cloned, and the expressed protein has been named SnSAG1. In a previous study, cell-mediate...

As well as being considered a reliable measurement instrument of animal anxiety-like behavior, the elevated plus-maze (EPM) is also used as a post-hoc test to evaluate emotionality in genetically modified rodents. The present review considers factors which may further improve the validity (predictive/face/construct) of the EPM model: (1) the importance of measuring defensive patterns of respons...

There has been a steady decline in the number of applications to nephrology training programs. One solution is to decrease the number of available fellowship positions. Proponents believe that training programs have grown too big but the method for reduction has not been established. This investigation analyzes two models that decrease the number of available training positions and compares the...
