Studies on talker normalization have reported that contexts would affect how a vowel/consonant/tone is perceived, which suggests that listeners use cues in the context as a reference for speech perception. However, it is unclear how the cues of the context are encoded in memory, and to what extent the context effects are influenced by interruption in sensory memory and reduction in attentional ...

PLS Generalised Linear Regression: foundations and recent advances with variable selection and validation procedures Vincenzo Esposito Vinzi Universita degli Studi di Napoli; [email protected] PLS (Partial Least Squares) univariate regression (PLS1) is a model linking a numerical dependent variable to a set of numerical (or dummy) explanatory variables especially feasible in situa...

INTRODUCTION Brachial plexus blockade is a time-tested technique for upper limb surgeries. The classical approach using paresthesia technique is a blind technique and may be associated with a higher failure rate and injury to the nerves and surrounding structures. To avoid some of these problems, use of peripheral nerve stimulator and ultrasound techniques were started which allowed better loca...

Background The rationale for injection of epidural medications through the needle is to promote sooner onset of pain relief relative to dosing through the epidural catheter given that needle injection can be performed immediately after successful location of the epidural space. Some evidence indicates that dosing medications through the epidural needle results in faster onset and improved quali...

 Abstract Background: Different adjuvant drugs have been used with local anesthetics in order to decrease the time of onset and elongate the duration and quality of regional blocks. This study was performed to study the effects of one of the adjuvants, verapamil, in supraclavicular block. Methods: In this double blinded clinical trial, we divided 60 ASA class I and II patients who were to under...

BACKGROUND Before caesarean section is performed under regional anaesthesia the block should be assessed, preferably using a touch stimulus. What constitutes a touch stimulus remains unclear. The aim of this study was to compare a Neuropen monofilament with ethyl chloride in the assessment of touch. METHODS Forty women undergoing elective caesarean section received combined spinal-epidural an...

Background: Several clinical studies have shown that clonidine prolongs sensory motor blockade when used with bupivacaine but ideal doses of clonidine on ropivacaine is not well defined and to evaluate the effect of two doses of clonidine on ropivacaine, for supraclavicular brachial plexus blockade. Methods: In a prospective randomized double blind study supraclavicular brachial plexus blockade...

Background: Although various adjuvants have been added to local anesthetic agents potentiate its effect, dexmedetomidine is a relatively new drug with only fewer studies. Aims and Objectives: The present study has conducted compare the efficacy of intrathecal hyperbaric bupivacaine alone two different doses as in spinal anesthesia for lower abdominal surgery. Materials Methods: This was double-...
