After chronic axotomy retrograde transport is impaired in LDPT neurons, but can be reinitiated by re-axotomy. Our results also indicate that FG is metabolized/lost from retrogradely labeled neurons at increasing survival times, and that this process appears to be accelerated by injury. (C) 2011 IBRO.

“Purpose: An accurate, complete understanding of the prostate neuroanatomy is required to optimize nerve sparing

techniques during radical prostatectomy. However, the precise topography and function of the periprostatic nerves remain contentious and there is Belnacasan mouse uncertainty about which nerve sparing technique is most optimal. We accurately quantified the distribution, precise localization and cross-sectional area of periprostatic neural tissue using cadaveric specimens.

Materials

and Methods: We analyzed 13 cadaveric Selleck Quizartinib hemipelves using hematoxylin and eosin stained sections from the base, mid zone and apex of each prostate. Each section was digitized and divided into 6 sectors numbered clockwise. Analysis was performed using National Institutes of Health ImageJ software to calculate the total periprostatic neural cross-sectional area per sector.

Results: Calculating the total neural cross-sectional area highlighted a decrease from prostate base to mid zone to apex of 24.7, 19.7 and 13.7 mm(2), respectively. Most neural tissue was located in the posterolateral region. However, the proportion surrounding the anterior part of the prostate increased toward the apex with a median of 6.0% and 7.6% at the base and mid zone regions, respectively,

increasing to 11.2% at the apex.

Conclusions: Simple numerical nerve quantification may be insufficient to accurately describe the periprostatic neural distribution. Calculating nerve bundle cross-sectional area confirmed that most neural tissue is in the posterolateral region, although the proportion located anterior increases from base to apex. Thus, higher release of the periprostatic fascia may be indicated toward the apex.”
“The creatine-phosphocreatine shuttle is essential for the maintenance of cellular ATP, particularly under hypoxic conditions when respiration may become anaerobic. Using a model of intrapartum MK1775 hypoxia in the precocial spiny mouse (Acomys cahirinus), the present study assessed the potential for maternal creatine supplementation during pregnancy to protect the developing brain from the effects of birth hypoxia. On day 38 of gestation (term is 39 days), the pregnant uterus was isolated and placed in a saline bath for 7.5 min, inducing global hypoxia. The pups were then removed, resuscitated, and cross-fostered to a nursing dam. Control offspring were delivered by caesarean section and recovered immediately after release from the uterus.
