introduction: septal deviation is the chief cause of chronic nasal obstruction. in order to treat such cases, nasal septoplasty surgery is usually performed based on patient complaints and a surgeon's examination, both of which are subjective. this study aims at using the objective parameters of acoustic rhinometry and rhinomanometry to evaluate the effectiveness of septoplasty surgery.   ...

objectives: new digital two-dimensional imaging systems are considered as an easily accessible modality for sinonasal evaluation. the aim of this study was to assess the diagnostic efficacy of digital waters’ and caldwell’s radiographic views for evaluation of sinonasal area. materials and methods: a total of 273 patients fulfilling the inclusion criteria were enrolled in this descriptive-analy...

Introdouction: The mapping of ghost images of the maxilla and the nasal cavity, which are complex structures, is very important. The position of objects that create a ghost image can differ when using various devices. The purpose of this investigation was to study the mapping of ghost images of the maxilla and the nasal cavity using a Cranex D digital panoramic machine. Materials and methods: ...

The supramammillary area of the hypothalamus, although small in size, can have profound modulatory effects on the hippocampal formation and related temporal cortex. It can control hippocampal plasticity and also has recently been shown to contain cells that determine the frequency of hippocampal rhythmical slow activity (theta rhythm). We review here its organization and anatomical connections ...

OBJECTIVE To determine whether regional hypoperfusion of the interventricular septum occurs during ventilation with positive end-expiratory pressure. DESIGN Animal study. ANIMALS Anesthetized, closed chest dogs (n = 8). INTERVENTIONS Induction of experimental adult respiratory distress syndrome (ARDS) and then ventilation with 10, 15, and 20 cm H2O of positive end-expiratory pressure. M...

During cytokinesis, fission yeast and other fungi and bacteria grow a septum that divides the cell in two. In fission yeast closure of the circular septum hole by the β-glucan synthases (Bgs) and other glucan synthases in the plasma membrane is tightly coupled to constriction of an actomyosin contractile ring attached to the membrane. It is unknown how septum growth is coordinated over scales o...

ume overload was created in open-chest dogs by pumping blood from the left atrium to the right atrium. In seven of eight dogs changes in interventricular septum motion were produced acutely at shunt flow as low as 500 cc/min. When the shunt was decreased or stopped, interventricular septum motion returned to normal. Shunts producing left ventricular volume overload (aorta to left atrium and rig...
