The recent cloning of two GABA(B) receptor subunits, GABA(B1) and GABA(B2), has raised the possibility that differences in GABA(B) receptor subunit composition may give rise to pharmacologically or functionally distinct receptors. If present, such molecular diversity could permit the selective targeting of GABA(B) receptor subtypes specifically involved in(More)
Voltage-gated sodium channels (VGSCs) are vital for the normal functioning of most excitable cells. At least nine distinct functional subtypes of VGSCs are recognized, corresponding to nine genes for their pore-forming alpha-subunits. These have different developmental expression patterns, different tissue distributions in the adult and are differentially(More)
We reviewed the clinical and fine-needle aspiration (FNA) findings in 20 patients with poorly differentiated carcinomas presenting initially as parotid or as submandibular masses. There were 11 primary tumors and nine metastatic malignancies in 14 males and six females ranging in age from 39 to 89 yr (median = 66). The tumor types included three primary(More)
The recently developed GABAB1 receptor subunit knockout (GABAB1 -/-) mouse displays complete loss of GABAB receptor function and develops complex generalized epilepsies including absence type, audiogenic as well as spontaneous generalized seizures with electrographic spike-wave discharge signatures. To gain insight into the cellular mechanisms contributing(More)
Genes encoding the α subunits of neuronal sodium channels have evolutionarily conserved sites of alternative splicing but no functional differences have been attributed to the splice variants. Here, using Na(V)1.7 as an exemplar, we show that the sodium channel isoforms are functionally distinct when co-expressed with β subunits. The gene, SCN9A, encodes(More)
Pathological changes in axonal function are integral features of many neurological disorders, yet our knowledge of the molecular basis of axonal dysfunction remains limited. Microfluidic chambers (MFCs) can provide unique insight into the axonal compartment independent of the soma. Here we demonstrate how an MFC based cell culture system can be readily(More)
Fungal infections of the breast are unusual and may clinically mimic carcinoma. When studied by fine-needle aspiration (FNA), such masses may yield necrosis, granulomatous inflammation, reactive histiocytes, and atypical epithelial cells. Cohesive groups of atypical epithelial cells featured nuclear enlargement and overlapping, as well as prominent(More)
Hyperpolarization-activated cyclic nucleotide gated (HCN) ion channels regulate membrane potential, neurotransmitter release, and patterning of synchronized neuronal activity. Currently, there is an intense debate as to whether or not these ion channels play a pro- or anticonvulsant role in vivo. To gain an insight into this question, we have examined how(More)
Farmer, C. and Palin M.-F. 2008. Feeding flaxseed to sows during late-gestation and lactation affects mammary development but not mammary expression of selected genes in their offspring. Can. J. Anim. Sci. 88: 585 590. Mammary gland composition and mammary gene expression were measured in pubertal gilts whose dam were fed a control (CTL) diet or a diet with(More)
