A technique employing a nerve stimulator and an insulated needle was used for supraclavicular brachial plexus block in 71 patients using 0.5% plain bupivacaine 15-20 ml. The mean minimal stimulating current to produce paraesthesia was 0.09 mA. The plexus was identified at a mean depth of 27 mm below the skin. The block was successful in 98% of patients when the stimulation was felt in the index...

A P300 (P3)-evoked response is generated in a variety of mammalian species upon detection of significant environmental events. The P3 component has been proposed to index a neural system involved in attention and memory capacity. We investigated the contribution of anterior and posterior association cortex to somatosensory P3 generation. Somatosensory event-related potentials (ERPs) were record...

We studied the variations in the ventral rami of 152 brachial plexuses in 77 Korean adults. Brachial plexus were composed mostly of the fifth, sixth, seventh and eighth cervical nerves and the first thoracic nerve (77.0%). In 21.7% of the cases examined, the fourth, fifth, sixth, seventh and eighth cervical and the first thoracic nerves contributed to the plexus. A plexus composed of the fourth...

BACKGROUND Myofascial pain (MP) is a common disorder that can involve any skeletal muscle in the human body. There are no published reports of the referred pain patterns of the third and fourth dorsal interosseous muscles. OBJECTIVE To investigate the referred pain patterns of the third and fourth dorsal interosseous muscles. STUDY DESIGN Prospective evaluation. SETTING Academic medical c...

to study the effect of harvesting time on soybean seed germination and vigor a factorial experiment with three replications, including of five harvesting time and three soybean cultivars was carried out in the field and glasshouse. the effect of harvesting time on seed germination percentage (in the field, cold test and paper test), seed germination rate, shoot and root weights, 1000-seed weigh...

OBJECTIVES To investigate the prevalence, gender influence, and relationships between burnout, depression and suicidal ideation within the last year among second, fourth and fifth-year dental students. STUDY DESIGN A cross-sectional study was carried out in 212 dental students enrolled in the second, fourth and fifth years at the School of Dentistry of Seville using the Maslach Burnout Invent...

A 12-year-old African American girl presented with a 1-year history of swelling and intermittent pain in her left foot. The swelling and pain had worsened over the past 3 weeks. She reported that prolonged walking increased the pain and swelling, while laying down lead to some improvement. The patient and her mother denied trauma to the left foot. There was no history of fever, nausea, vomiting...

Using a quasiexperimental design, the authors examine whether fourth- and fifth-grade students exposed to a developmental physical education (PE) curriculum, Michigan's Exemplary Physical Education Curriculum (EPEC), demonstrated stronger motor skill-specific self-efficacy and perceptions of physical activity competence, physical activity levels, motor skills, and physical fitness than did stud...

During the educational dissection of a 69-year-old Chinese male cadaver, an extensor digiti minimi (EDM) with five slips on the right hand was discovered. Except for the two slips of the little finger, the two radial slips were inserted into the dorsal aponeurosis of the middle finger and the ring finger, respectively. The middle slip was connected to the junctura tendinum in the fourth interme...
