The objective of this study was to determine if simple, shoulder movements use the dual control hypothesis strategy, previously demonstrated with elbow movements, and to see if this strategy also applies in the absence of visual feedback. Twenty subjects were seated with their right arm abducted to 90 degrees and externally rotated in the scapular plane. Subjects internally rotated to a target ...

Finding the origin of slow and infra-slow oscillations could reveal or explain brain mechanisms in health and disease. Here, we present a biophysically constrained computational model of a neural network where the inclusion of astrocytes introduced slow and infra-slow-oscillations, through two distinct mechanisms. Specifically, we show how astrocytes can modulate the fast network activity throu...

BACKGROUND Baroreceptor-mediated phasic changes in vagal tone have been hypothesized to cause ventriculophasic sinus arrhythmia (VPSA). The objectives of this study were to demonstrate ventriculophasic modulation of AV nodal conduction and to substantiate the role of the baroreflex on ventriculophasic AV nodal conduction (VPAVN) by pharmacological perturbation of parasympathetic tone. METHODS...

activity measured by reflected infra-red light. PHYSIOL. BEHAV. 28(5) 851-854, 1982.-A simple, reliable and inexpensive device for continuously monitoring pupillary changes is described. It is an improved version of a device first suggested by L. Stark. Infra-red light is transmitted to the iris and reflected back onto the receiver. Consequently, the device is effective only if the eye is immob...

Cardiovascular diseases (CVDs) are debilitating conditions with long-term physical and psycho-logical consequences (1). After a cardiac event or procedure, the patient encounters several problems, two of the most important of which are psychosexual dysfunction and difficulty in resuming sexual activity (2-4). The World Health Organization (WHO) defines sexual health as a state of physical, emot...

Evidence supports a clear racial variation in the position of the infraorbital foramen. Therefore detailed knowledge of the population specific data on biometric features of the infraorbital foramen will facilitate therapeutic, diagnostic and surgical manipulations in the maxillo-facial region. The goal of this study was to elucidate the morphological features and precise anatomical position of...

Background and Objective: Doxorubicin is one of the most common drugs for chemotherapy. The complications of doxorubicin are cardiac toxicity due to oxidative stress. Cydonia oblonga Miller leaf (COL) contains flavonoids and phenolic antioxidants. Due to the presence of antioxidant compounds in COL, the aim of this study was to evaluate the effect of hydroalcoholic extract of COL on doxorubicin...
