The role of mitochondria within injured neurons is an area of active interest since these organelles are vital for the production of cellular energy in the form of ATP. Using mechanosensory neurons of the nematode Caenorhabditis elegans to test regeneration after neuronal injury in vivo, we surveyed genes related to mitochondrial function for effects on axon regrowth after laser axotomy. Genes ...

OBJECTIVES AND DESIGN We performed a prospective study using magnetic resonance imaging (MRI) at regular post-operative intervals in non-irradiated patients with non-functioning pituitary adenomas (NFAs) to assess the frequency of tumoral regrowth and recurrences, in order to define the indications of post-operative radiotherapy. PATIENTS AND METHODS Fifty-one patients aged 25--80 years (mean...

Influence of Water Treatment Processes Statistical analyses were conducted with historical data from the South Central Connecticut Regional Water Authority (SCCRWA) to determine if parameters determined in the treatment plants were related in any way to coliform counts in the distribution system. The analysis indicated that sufficient chlorination for maintaining treatment effluent standards fo...

Spectral regrowth in power amplification of digitally modulated signals can be partly explained by considering intermodulation of discrete signals. A full description however requires statistical modelling. An accurate modelling approach for predicting spectral regrowth and the origins of asymmetric adjacent channel distortion in digital radio are presented.

OBJECTIVE The present study aimed to assess the nitrogen (N) use efficiency of acidified pig slurry for regrowth yield and its environmental impacts on perennial ryegrass swards. METHODS The pH of digested pig slurry was adjusted to 5.0 or 7.0 by the addition of sulfuric acid and untreated as a control. The pig slurry urea of each treatment was labeled with 15N urea and applied at a rate of 2...

OBJECTIVE To estimate and compare the incidence rate of kidney stone recurrence and regrowth after ESWL with PCNL at one, two, and three years. MATERIAL AND METHOD A retrospective cohort study was performed The study recruited patients aged more than 18 years, diagnosed with kidney stones and treated by ESWL or PCNL between January 2006 and August 2010 at the urological unit of a university h...

Twenty-seven patients with severe alopecia areata were treated with dapsone. The results of a mean treatment duration of 10 +/- 0.5 months are reported, and compared with the results of long-term topical immunotherapy obtained previously at the same institute. The efficacy of dapsone proved to be markedly inferior to that of topical immunotherapy. The percentage of patients showing regrowth of ...

Thunderclap headache is a sudden, high-intensity headache often associated with subarachnoid hemorrhage secondary to a ruptured intracerebral aneurysm. A variety of less common causes have now been described. This report presents the cases of 2 patients who experienced thunderclap headache after regrowth of an aneurysm, without hemorrhage of previously coiled aneurysms. Thunderclap headache aft...
