Bilateral sectioning of the esophageal nerves that innervate the gut of Aplysia was found to have profound effect on response decrement to inedible food: Time to criterion for cessation of feeding was elevated, no memory of the decrement was present 24 hr after training, and motor patterning during training was altered. The parametric features of response decrement to sustained lip stimulation ...

The aim of this study was to evaluate the mesiobuccal root of maxillary first molars, according to the root canal configuration, prevalence and location of isthmuses at 3 and 6 mm from the apex, comparing cone-beam computed tomography (CBCT) analysis and cross sectioning of roots by thirds. Images of the mesiobuccal root of 100 maxillary first molars were acquired by CBCT and then roots were cr...

The study of cytological fine structure with the electron microscope, has as an important prerequisite, the ability to cut consistently good quality thin sections. Satisfactory techniques for doing this are well known in many laboratories and an excellent review of the subject has recently been published by Farquhar (1). However, some of the details of the practice of microtomy are not in the l...

As electron microscopic techniques have improved, the fine structure of bacterial cells has come to be understood more clearly. There are, however, many details yet to be elucidated. I propose to report here some observations on the plasma membrane of Staphylococcus aureus, using sectioning techniques. Bradfield (1956) has already described some structural features of Staphylococcus aureus usin...

Dynamic speckle illumination (DSI) provides a simple and robust technique to obtain fluorescence depth sectioning with a widefield microscope. We report a significant improvement to DSI microscopy based on a statistical image-processing algorithm that incorporates spatial wavelet prefiltering. The resultant gain in sectioning strength leads to a fundamentally improved scaling law for the out-of...

BACKGROUND Isolated radial head dislocation is a rare injury with an unclear pathomechanism, and the treatment is controversial. The purpose of the present study was to investigate the biomechanical contributions of the annular ligament, quadrate ligament, interosseous membrane, and annular ligament reconstructions to proximal radioulnar joint stability. METHODS Five fresh frozen cadaveric up...
