Studies on a quantitative separation and analysis of chloroplastic matter by different investigators have revealed that chlorophyll is held by chemical forces on proteinaceous matter. This matter, named phyllochlorin by MESTRE (17), chloroplastin by STOLL (37), photosynthin by FRENCH (8), and chloroglobin by RABINOWITCH (21), is presumably identical with the substance composing the stroma of ch...

Neurosurgery is considered to be one of the most challenging of all careers, as captured by the cliché, “it’s not brain surgery”. While the neurosurgeons who spoke to MJA reers for this issue’s Career Overview ry did emphasise the technical demands their specialty, they also said the clinical d cognitive challenges of neurosurgery re part of its appeal (page C1).

background: carpal tunnel syndrome (cts) is one of the most common musculoskeletal disorders among computer users. computer users exhibit various wrist angles while typing. dynamic changes of wrist angle may cause different degrees of median nerve compression. the objective of this study was thus to investigate the effects of the combination of wrist flexion-extension with wrist deviation on me...

several previous studies of adults have reported that the amplitudes of the sural and superficial radial nerve (sn and srn) action potentials are larger with antidromic than with orthodromic recordings. however, this difference has not been documented in children. this study evaluated the amplitudes of sn and srn sensory nerve action potentials (snaps), obtained with antidromic and orthodromic ...

background: the standard method for repair of an injured peripheal nerve is epineural repair with separate sutures. herein we describe a method in which the nerve is sutured with continous sutures. in fact this method has not been utilized for nerve repair previously and our purpose was to compare it to the standard method. if it proved to be successful it would replace the standard method in c...

during the past few years, researchers and practitioners have developed novel techniques, using ansa cervicalis to innervate muscles of the larynx paralyzed due to surgical procedures carried out in the chest and neck areas. during routine dissection of a middle-age male cadaver, an unusual course of the superior root of the ansa cervicalis was observed. in this case, the superior root of the a...

OBJECTIVE To evaluate the incidence of Frey syndrome (auriculotemporal nerve syndrome) after parotidectomy with and without placement of a subcutaneous implant and to examine the relationship between different implants and postoperative wound complications (hematoma, seroma, salivary fistula). DESIGN A prospective nonrandomized controlled trial. SETTING A primary care and referral universit...

background lumbar plexus block (lpb) is one of the anesthetic options in the elderly patients undergoing hip surgeries. lpb could be safe because it targets somatic nerve in psoas region. effectiveness of lpb is attributed to the sufficient analgesia provided intraoperatively as well as postoperatively. adequate muscle relaxation and immobility during surgery refers to its acceptability. object...
