Reducing the foot trajectory variabilities during walking through vibratory stimulation of the plantar surface of the foot.

Variabilities or fluctuations in foot clearance are considered as a risk factor for falls during walking in older adults. The present study aimed to investigate whether the foot trajectory variability can be reduced by applying vibratory stimulation to the foot's plantar surface during walking. Ten healthy adults were asked to walk on a treadmill with vibratory shoes, and body kinematics were measured.

Morphologic Evaluation of the Mitral Annulus During Displacement of the Heart in Off-Pump Coronary Artery Bypass Surgery.

Objective: To evaluate the morphologic changes of the mitral annulus using 3-dimensional transesophageal echocardiography during heart displacement to expose the anastomosis site in off-pump coronary artery bypass surgery (OPCAB).

Design: Prospective case series.

Setting: Single center, university hospital.

[Anesthetic management of patients with tracheal bronchus].

The incidence of a tracheal bronchus supplying the right upper lobe has been reported to be in the range of 0.1 to 3%. We encountered 3 cases with the anomaly among 200 cases of lung surgery conducted over a year at our hospital.

Effects of the mono- and tetrasialogangliosides GM1 and GQ1b on ATP-induced long-term potentiation in hippocampal CA1 neurons.

The effects of the mono- and tetrasialogangliosides, GM1 and GQ1b, on ATP-induced long-term potentiation (LTP) were studied in CA1 neurons of guinea pig hippocampal slices. Application of 5 or 10 microM ATP for 10 min resulted in a transient depression followed by a slow augmentation of synaptic transmission, leading to LTP. LTP induced by treatment with 5 microM ATP was facilitated in hippocampal slices prepared from animals treated for 6 days with a ceramide analog, L-threo-1-phenyl-2-decanoylamino-3-morpholino-1-propranol, which stimulates ganglioside biosynthesis.
