[EX Q]: Abstract: During a 6-year period, 14 of 898 patients examined at a pediatric electromyographic laboratory had a compressive mononeuropathy. These included five injuries to the peroneal nerve, four to the sciatic nerve, two to the distal radial nerve, and one each to the deep palmar branch of the ulnar nerve, the musculocutaneous nerve, and the long thoracic nerve. A potentially preventable mechanism was identified in 9 of the 14 patients, including prolonged posture in three of the four sciatic and two of the peroneal neuropathies. Four other mononeuropathies were secondary to pressure from an orthopedic appliance or procedure (one injury to the musculocutaneous nerve, one to the long thoracic nerve, two to the peroneal nerve).

[EX Q]: Abstract: We have determined the structures of high mannose (Man) oligosaccharide units of the alpha- and beta-subunits of mouse TSH heterodimers and of free alpha-subunits. Mouse thyrotropic tumor tissue, or pituitaries from euthyroid or hypothyroid mice, were incubated with D-[2-3H]Man, homogenized, and incubated in the presence or absence of pH 3 buffer to dissociate heterodimers. Highly enriched TSH beta-subunits, or TSH heterodimers, were obtained using anti-TSH beta serum and free alpha-subunits were subsequently obtained using anti-LH alpha-serum. High Man units released by endoglycosidase H were analyzed by paper chromatography. At 1 and 3 h oligosaccharides with 8 or 9 Man residues predominated in all subunits. In all three tissue types, units with 9 Man tended to accumulate in TSH beta-subunits, whereas Man-trimming from Man9GlcNAc to Man8GlcNAc proceeded more rapidly in TSH alpha-subunits, and in free alpha-subunits. The rate of TSH beta-subunit processing was also a function of tissue type; the rate in euthyroid pituitary tissue equaled that in tumor tissue and was greater than that in hypothyroid pituitary tissue, suggesting that processing may be physiologically regulated. Hypothyroid calf serum slowed TSH alpha-subunit processing in euthyroid pituitaries. Thus, the previously reported slower processing of Man9GlcNAc to Man8GlcNAc in heterodimers as compared to free alpha-subunits is in large part due to accumulation of Man9GlcNAc in TSH beta-subunits.

[EX Q]: Abstract: During development, cells become progressively restricted, until they reach their final phenotype. Differentiation was originally thought to be irreversible, but phenotypic plasticity has been observed in a variety of cell types, for example sympathetic neurones, the limb blastema and some glial cell types. A detailed description of the individual steps that lead to expression or reversal of phenotype is essential to understand the molecular events underlying cell differentiation. We examined whether ciliary neurones acquire adrenergic properties when exposed to a permissive embryonic environment. Cholinergic neurones were selectively labelled with a retrogradely transported marker and injected into chick embryos during active neural crest migration. Four to five days after injection, some of the labelled neurones were found in 'adrenergic sites' and had developed catecholamine histofluorescence. The cells had thus accumulated adrenergic neurotransmitters even after differentiation into cholinergic neurones. This result shows that neurotransmitter plasticity occurs in cholinergic neurones and suggests that the neurotransmitter phenotype can be modified by the embryonic environment.
