Faust D, Happel L
Orthopedics . 2014 May; 7(1):44-8. PMID: 24823090
Few complications of surgery are as devastating as paraplegia in a patient who has been operated on for correction of a spinal abnormality. Early warning of potential damage to the...

Kretschmer T, Happel L, England J, Nguyen D, Tiel R, Beuerman R, et al.
Acta Neurochir (Wien) . 2002 Aug; 144(8):803-10; discussion 810. PMID: 12181690
Background: The axolemmal distribution and density of voltage-gated sodium channels largely determines the electrical excitability of sprouting neurites. Recent evidence suggests that accumulation of sodium channels at injured axonal tips...

Clark G, Zorumski C, McNeil R, Happel L, Ovella T, McGuire S, et al.
Neurochem Res . 2000 Jul; 25(5):603-11. PMID: 10905621
In most nonneural systems, platelet-activating factor (PAF) receptor effects are mediated by G-proteins that are often pertussis toxin-sensitive. The activation of pertussis toxin-sensitive G-proteins linked to PAF receptors results in...

England J, Happel L, Liu Z, Thouron C, Kline D
Neurosci Lett . 1998 Dec; 255(1):37-40. PMID: 9839721
Twenty-seven human traumatic neuromas were examined immunocytochemically using highly specific antibodies directed against the voltage-gated delayed-rectifier potassium channel, Kv1.1. Normal sural nerves from six of the above-noted patients served as...

England J, Happel L, Kline D, Gamboni F, Thouron C, Liu Z, et al.
Neurology . 1996 Jul; 47(1):272-6. PMID: 8710095
Painful neuromas from 16 patients were examined using site-specific antisodium channel antibodies employed in immunocytochemical and radioimmunoassay methods. Normal sural nerves from six of these patients served as controls. Immunocytochemistry...

Kline D, Happel L
Can J Neurol Sci . 1993 Feb; 20(1):3-10. PMID: 8467425
The rationale, basic considerations, and technique of intraoperative nerve action potential (NAP) recording have been reviewed. Experience using this technique in several thousand patients over a 25 year period has...

Clark G, Happel L, Zorumski C, Bazan N
Neuron . 1992 Dec; 9(6):1211-6. PMID: 1334422
The biologically active lipid platelet-activating factor (1-O-alkyl-2-acetyl-sn-glycero-3-phosphorylcholine; PAF) is a mediator of inflammatory and immune responses, and it accumulates in the brain during convulsions or ischemia. We have examined whether...

Schutte M, Happel L
Clin Sports Med . 1990 Apr; 9(2):511-7. PMID: 2183957
When considering joint innervation, it is important to appreciate that the joint receptors and the muscle tendon units about the joint interact in a complimentary manner forming a single afferent...

Carey M, Sarna G, Farrell J, Happel L
J Neurosurg . 1989 Nov; 71(5 Pt 1):754-64. PMID: 2509646
Among civilians in the United States, 33,000 gunshot wound deaths occur each year; probably half of these involve the head. In combat, head wounds account for approximately half of the...

Schutte M, Dabezies E, Zimny M, Happel L
J Bone Joint Surg Am . 1987 Feb; 69(2):243-7. PMID: 3805085
The histology of the anterior cruciate ligament was studied by a modified technique of the Gairns gold chloride stain for neural elements. Three morphological types of mechanoreceptors and free nerve-endings...
