For the understanding of the developmental significance of various parts of the normal ventricular septum, 54 normal human embryos and 154 mature heart specimens showing different types of VSD’s and AV canal malformation were studied. The pars interventriculare of the septum membranaceum is derived primarily from the right superior and inferior tubercies of the AV cushions. The pars atrioventri...

CALARESU, FRANCO R., AND GORDON J. MOGENSON. Cardiovascular responses to electrical stimulation of the septum in the rat. Am. J. Physiol. 223(4): 777-782. 197 2 .-Cardiovascular responses to electrical stimulation of histologically verified sites in the septum were studied in 60 rats. In animals under a-chloralose anesthesia stimulation of the lateral septum (24 sites) elicited arterial hypoten...

OBJECTIVES The objectives of this study were to describe and compare two techniques used to correct nasal septum deviations located in the dorsal and/or caudal septum. STUDY DESIGN The authors conducted a retrospective clinical chart review. METHODS The authors conducted a comparison of functional and technical results between surgery in the L-strut of the septum in 114 patients with septal...

The development of olfactory bulb projections that form the lateral olfactory tract (LOT) is still poorly understood. The septum and the olfactory cortex have been shown to secrete diffusible factors repelling olfactory axons in vitro and are likely to cause the axons to avoid the septum region in vivo. Slit2, a member of the Slit gene family, has been proposed to be this septal factor based on...

Intracerebroventricular administration of corticotropin-releasing hormone (CRH) elicits a constellation of behavioral, autonomic, and endocrinological changes typically observed in stress. One of the behavioral changes after intracerebroventricular CRH is a profound increase of startle amplitude (CRH-enhanced startle). The present study examined the role of the septum in CRH-enhanced startle. T...

The interatrial septum has not been readily appreciated by M-mode echocardiography. Cross-sectional echocardiography has the capability of recording the shape and location of the interatrial septum. Real-time cross-sectional echograms using a mechanically oscillating transducer were obtained on 100 consecutive patients. Echocardiographic examination of the left atrium and aorta was obtained in ...

The objective of this study was to ascertain if incomplete correction leaving a residual uterine septum of < or = 1 cm affects fertility outcome. Reproductive outcome in 17 women with a residual septum of between 0.5 cm and 1 cm after hysteroscopic metroplasty was compared to that in 51 women with no residual septum or one of < 0.5 cm. Septal lysis was performed with microscissors or resectosco...

Myocardial fiber diameters were measured to determine their distribution throughout the ventricular wall in normal adult hearts, hypertensive hearts and hearts with hypertrophic cardiomyopathy (HCM). In normal adult hearts and hypertensive hearts, the diameter decreased from the inner to the outer third of the left ventricular free wall and from the left ventricular side to the right ventricula...

Projections from the nucleus incertus (NI) to the septum have been implicated in the modulation of hippocampal theta rhythm. In this study we describe a previously uncharacterized projection from the septum to the NI, which may provide feedback modulation of the ascending circuitry. Fluorogold injections into the NI resulted in retrograde labeling in the septum that was concentrated in the hori...

Background & Aims: One of the important aims of quantitative cardiac image processing is the clarification of myocardial motions in order to derive biomechanical behavior of the heart in the disease condition. In this study we presented a computerized analysis method for detecting the instantaneous myocardial changes by using 2D echocardiography images. Methods: The analysis was performed on th...
