BACKGROUND: Short Latency Somatosensory Evoked Potentials (SEPs) may serve to the testing of the somatosensory tract function, which is vulnerable and affected in vascular encephalopathy. The aim of the current study was to search for clinical and neuroimaging correlates of abnormal SEPs in vascular dementia (VD) patients. MATERIALS AND METHODS: The study included 14 VD patients, aged 72.93 Plu...
The small GTP-binding proteins Rac and Rho are key elements in the signal-transduction pathways respectively controlling the formation of lamellipodia and stress fibers induced by growth factors or oncogenic Ras. We recently reported that Rac function is necessary for Ras transformation and that expression of constitutively activated Rac1 is sufficient to cause malignant transformation. We now ...

The central nervous system can experience a number of stresses and neurological insults, which can have numerous adverse effects that ultimately lead to a reduction in neuronal population and function. Damaged axons can release excitatory molecules including potassium or glutamate into the extracellular matrix, which in turn, can produce further insult and injury to the supporting glial cells i...
Highly specialized cells, the thyrocytes, express a thyroid-specific set of genes for thyroglobulin (Tg), thyroperoxidase, and the transcription factors TTF-1, TTF-2, and Pax-8. The implication of the small GTPase RhoA in TSH-mediated proliferation of FRTL-5 rat thyroid cells has been previously demonstrated. To further analyze RhoA function in thyroid cell proliferation and differentiation pat...
S t u d y s e l e c t i o n Studies were selected if they were published in English; assessed the association between SEPs (initial cortical responses from median nerve stimulation—i.e., the N19 or N20 responses) and awakening from coma; and reported coma cause, age group studied, presence or absence of SEP responses, timing of SEPs, and coma outcomes. Study exclusion criteria included single c...
The SrrAB system regulates metabolism and virulence factors in Staphylococcus aureus. We sequenced the srrAB loci of 21 isolates and performed a phylogenetic analysis. Vaginal and bovine isolates clustered together, while skin isolates were genetically diverse. Few nucleotide polymorphisms were observed, and most were synonymous. Two strains (N2 and N19) with N-terminal truncations in SrrA disp...
The classic myelin basic protein (MBP) family of central nervous system (CNS) myelin arises from transcription start site 3 of the Golli (gene of oligodendrocyte lineage) complex and comprises splice isoforms ranging in nominal molecular mass from 14 kDa to (full-length) 21.5 kDa. We have determined here a number of distinct functional differences between the major 18.5-kDa and minor 21.5-kDa i...
The intestinal epithelial barrier, which is regulated by the actin cytoskeleton, exhibits permeability changes during inflammation. Here we show that activation of the CysLT(1) receptor by the inflammatory mediator leukotriene D(4) (LTD(4)) causes a rapid increase in stress-fibre formation in intestinal epithelial cells. This effect was mimicked by cytotoxic necrotising factor-1 (CNF-1)-induced...
