1. Some flight motoneurones receive two superimposed rhythms of depolarizing synaptic potentials when the locust is not flying; a slow rhythm which is invariably linked to the expiratory phase of ventilation, and a fast rhythm with a period of about 50 ms which is similar to the wingbeat period in flight. 2. By recording simultaneously from groups of motoneurones, the synaptic potentials which ...

BACKGROUND Although atrial fibrillation (AF) termination has been reported as a predictor of clinical outcome after persistent AF (PsAF) ablation, the relationship between AF termination site and mode and clinical outcome has not been fully evaluated. METHODS AND RESULTS A total of 135 patients (62±9 years) underwent their first ablation procedure for PsAF (76 longstanding PsAF). With an endp...

We report here2 cases of patients with Sjögren’s syndrome with dry mouth that were successfully treated with cevimeline hydrochloride. The first case was diagnosed as Sjogren’s syndrome at our clinic, and the saliva secretion increased by more than three-fold following oral cevemeline hydrochloride. The second case was diagnosed at another hospital, and the saliva secretion was increased by mor...

Previous surveys conducted in commercial nurseries found that different wood fungi, namely Cylindrocarpon spp., Botryosphaeriaceae, Phomopsis viticola and Phaeomoniella chlamydospora infect grapevine cuttings. Two fi eld trials were carried out to evaluate the effectiveness of cyprodinil + fl udioxonil, pyraclostrobin + metiram, fl udioxonil and cyprodinil to prevent or reduce natural infection...

Degradative strains of fast-growing Mycobacterium spp. are commonly isolated from polycyclic aromatic hydrocarbon (PAH)-contaminated soils. Little is known, however, about the ecology and diversity of indigenous populations of these fast-growing mycobacteria in contaminated environments. In the present study 16S rRNA genes were PCR amplified using Mycobacterium-specific primers and separated by...

We investigate the dynamics of a three-dimensional system modeling molecular mechanism for circadian rhythm in Drosophila. first prove existence compact attractor region with biological meaning. Under assumption that dimerization reactions are fast, this we reduce to simpler two-dimensional on persistent normally hyperbolic slow manifold.

OBJECTIVES The objective of this study was to correlate electrocardiographic (ECG) PR interval changes during normal sinus rhythm with recent observations regarding the anatomy and physiology of the dual, slow and fast atrioventricular (AV) pathways. BACKGROUND The least common manifestation of dual AV conduction is an abrupt PR interval change in the setting of sinus rhythm. Whereas isolated...

Nerve growth factor (NGF) has an important role in regulating sympathetic neuron survival and target field innervation during development. Here we show that glucocorticoid-induced tumor necrosis factor receptor–related protein (GITR), a member of the TNF superfamily, and its ligand (GITRL) are co-expressed in mouse sympathetic neurons when their axons are innervating their targets under the inf...

Decades of research have demonstrated that a region of the right fusiform gyrus (FG) and right posterior superior temporal sulcus (pSTS) responds preferentially to static faces and biological motion, respectively. Despite this view, both regions activate in response to both stimulus categories and to a range of other stimuli, such as goal-directed actions, suggesting that these regions respond ...

In the foregoing chapter we have seen that language and music have similar kinds of structures and processes, both at the level of phrasing and at the rhythmic level. The remainder of this dissertation is about phrasing and rhythm phenomena in speech, while we keep musical phrasing and rhythm as the background motivation for several speech phenomena. The current chapter gives a (non-exhaustive)...
