Sometimes a discrete, tender pain-trigger point is no more than a few centimeters in diameter, but pressure upon it can cause it to be referred over a wider area. Most muscular pain is caused by either exercise or straining but may have been incurred with just routine chores

or even sneezing during sleep. My last patient had a discrete area of tenderness in the lateral rectus muscle and remembered, Vorinostat upon further discussion, perhaps lifting a heavier weight than usual in the gym shortly before this pain began. Clinically he had a small tear in his rectus sheath, although I did not see it on a prior CT scan. Solely on the basis of physical examination, I was able to suspect the diagnosis, reassure him, and discontinue the proton pump inhibitor. I prescribed a nonsteroidal anti-inflammatory drug, which gave him rapid relief, although whether it was the medication or my assurance that was more helpful, I do not know. I do know, however, that he was relieved and satisfied to have found a doctor who was comfortable in touching him and not just relying on the impersonal, albeit sophisticated, diagnostic imaging modalities so readily available today.

“GI stromal tumors

(GISTs) originating from the muscularis propria are challenging to diagnose and treat by endoscopy.1 and 2 Tissue acquisition by EUS guidance is often too scant for immunohistochemical diagnosis and mitotic index calculation.3 and 4 Resection by snaring and submucosal dissection has been reported, but carries Palbociclib a high risk of perforation.5, 6, 7 and 8 Tumor ligation

by using bands and loops reduces the risk of perforation,9, 10, 11 and 12 but can be technically difficult in nonpedunculated tumors and may not achieve complete ablation. To address current limitations of endoscopic diagnosis and therapy, we developed the retract-ligate-unroof-biopsy (RLUB) technique for upper GISTs. A novel retract-ligate-unroof-biopsy (RLUB) method enables endoscopic diagnosis and therapy of large (>2 cm) nonpedunculated stromal tumors. Active retraction of a stromal tumor can evert the bowel wall and may enable curative full-thickness ligation leading CYTH4 to tumor ablation. The RLUB technique was performed on consecutive patients with suspected upper GISTs on EUS examination starting in December 2010. All lesions fulfilled the following criteria: (1) broad based, (2) benign appearance on endoscopy (no ulceration or friability) (Fig. 1A), (3) benign appearance on EUS (well circumscribed, homogeneously hypoechoic, no cystic areas or calcifications), (4) originating from the muscularis propria layer on EUS, and (5) larger than 2 cm by maximum cross-section measurement on EUS. All patients were symptomatic and/or had a previous EUS-FNA diagnosis of GIST.

K. and B.R.Y.) from a resource of videos

from clinical trials of patients with active UC.8 Subjects had consented to the anonymized presentation of these procedures (EUDRACT 2006-001310-32). Each video comprised a full-length sigmoidoscopy, edited to remove contact friability test images where present, because this technical test had confused earlier assessment. Also included were recordings from subjects (Oxford LREC 536407Q1605/58ORH) without UC during colorectal cancer screening (“normal”) and from patients with the most severe UC who had been hospitalized, some before Selleckchem GSK2118436 emergency colectomy. All videos were anonymized throughout the study. A library of 57 videos was created and stratified by clinical disease activity using the Mayo Clinic score. Fifty of the videos were new (ie, not previously assessed in phases 1 or 2). Another 7 were MDV3100 ic50 repeated as benchmarks, comprising one each from extreme strata (ie, normal or most severe) and 5 with Mayo Clinic scores between 1 and 11. Each investigator was randomly assigned 28 of 57 videos in randomized order using a set of Latin squares (Table 2). Twenty-six of the 28 videos did not include clinical details. Each investigator was asked to evaluate the most severely affected area. Two duplicates of new videos (Mayo Clinic strata 1–2, 6–7, or 10–11)

were provided to evaluate intrainvestigator agreement. Another 2 videos were repeated and supplemented with clinical details (number of stools/day, severity of rectal bleeding, pretreatment or posttreatment status, and physician’s global assessment)

to evaluate prior knowledge of such clinical details on endoscopic evaluation. Videos were supplied in 3 batches over a 6-week period both to avoid reader fatigue and to optimize memory extinction for duplicated videos. Duplicates were arranged so that the first of any pair was in the first batch and the second was in the third batch. Abiraterone concentration Investigators were asked to evaluate the 3 descriptors comprising the UCEIS (Table 1) in the area worst affected at video sigmoidoscopy. In contrast to phase 2,6 still photographs from the training were provided for reference during evaluation to facilitate reference to the rating standards. A VAS (0–100) rating overall severity was similar to that used for phase 2. The VAS was used as a reference in the absence of a gold standard endoscopic assessment for reasons previously explained.6 To enable consistent and convenient data entry, investigators were provided with a data capture program designed by one of the authors (P.S.) that could be run simultaneously with video viewing and save responses after each video was scored. Data files were e-mailed to the sponsor after qualification assessments and for each cohort. The UCEIS was calculated as the simple sum of vascular pattern (scored 0–2), bleeding (scored 0 to 3), and erosions and ulcers (scored 0–3). Thus, the range of possible UCEIS scores was from 0 to 8.

306, P > 0.05). There was an interaction between time and stress (F(5,30) = 3.801, P < 0.05) and between time and hypercaloric diet (F(5,30) = 11.137, P < 0.05). In addition, there was time × stress × diet interaction (F(5,30) = 3.374, P < 0.05). There were no significant between-group differences for baseline weight (one-way ANOVA, P > 0.05, F(3,30) = 0.328, data not shown). For the weight delta (Δ = final weight − baseline weight) ( Fig. 1, Panel B), two-way ANOVA showed buy CHIR-99021 an effect of stress (F(1,30) = 14.599, P < 0.05) and diet (F(1,30) = 23.815, P < 0.05). The group means indicated that chronic stress reduced the weight

delta, whereas the hypercaloric diet increased the weight delta. Regarding the Lee index ( Fig. 1, Panel C), two-way ANOVA showed an effect of hypercaloric diet (F(1,30) = 10.224, P < 0.05) but no effect of stress (F(1,30) = 0.184, P > 0.05). Furthermore, there was an interaction between these independent factors (F(1,30) = 4.638, P < 0.05). The results from two-way ANOVA demonstrated the following results for the anthropometric parameters: in MAT, there was an effect of diet (F(1,30) = 14.846, P < 0.005) but no effect of stress (F(1,30) = 3.256, P > 0.05), and there was no interaction between these independent variables (F(1,30) = 0.041, P > 0.05). In SAT, there was an effect of diet www.selleckchem.com/products/DAPT-GSI-IX.html (F(1,30) = 37.479, P < 0.05)

but no effect of stress (F(1,30) = 2.717, P > 0.05), and there was no interaction between these independent variables (F(1,30) = 1.131, P > 0.05). In VAT, there was an effect of diet (F(1,30) = 22.599, P < 0.05) but no effect of stress (F(1,30) = 2.414, P > 0.05), and there oxyclozanide was no interaction between these independent variables (F(1,30) = 0.027, P > 0.05). The adrenal glands, as expected, showed an effect of stress (F(1,30) = 5.306, P < 0.05) but no effect of diet (F(1,30) = 2.484, P > 0.05), and there was an interaction between these independent variables (F(1,30) = 6.266, P < 0.05). The liver demonstrated no effect of stress (F(1,30) = 0.006, P > 0.05) or diet (F(1,30) = 2.553, P > 0.05), and there was no interaction between these independent variables (F(1,30) = 1.698, P > 0.05), demonstrating

that the chronic stress and hypercaloric diet did not alter the relative liver weight. The results of two-way ANOVA demonstrated the following for the biochemical and hormonal parameters: the leptin levels demonstrated an effect of diet (F(1,27) = 26.704, P < 0.05) but not stress (F(1,27) = 0.235, P > 0.05), and there was an interaction between these independent variables (F(1,27) = 5.05, P < 0.05). The statistical test demonstrated that the hypercaloric diet significantly increased the serum leptin levels after 40 days of exposure. The corticosterone levels did not demonstrate an effect of hypercaloric diet (F(1,26) = 0.052, P > 0.05) or chronic stress (F(1,26) = 1.643, P > 0.05), and there was no interaction between these independent variables (F(1,26) = 0.695, P > 0.05).

One patient experienced nTMS mapping as unpleasant, whereas no patient actually stated nTMS mapping was painful. Preoperative motor cortex mapping was compared to intraoperative DCS with a navigated DCS electrode. Borders between positive and negative stimulation points of both modalities were then compared on axial slices

by recalibrating screenshots and BrainLAB iPlan® Net Cranial 3.0.1. A difference of 4.5 ± 3.5 mm (range 1.9–9.2 mm) between nTMS and intraoperative DCS has been determined for the borders of the mapped primary motor cortex without observing any systematic monodirectional deviation (Figure 2 and Figure 3). Compared to nTMS data, determination of the primary motor cortex using BOLD data differed strongly between the upper and lower extremities. For the upper extremity, the deviation PS-341 cell line of nTMS and fMRI was 9.6 ± 7.9 mm (range 5.3–39.7 mm) (Fig. 3).

For the lower extremity, this difference was 15.0 ± 12.8 mm (range 8.4–33.5 mm) (Figure 2 and Figure 3). Again, no monodirectional systematic deviation could be observed. When using nTMS as the seed region for DTI-FT, we observed significantly HSP mutation less fibers within the tracked CST (nTMS: 916.0 ± 986.0 fibers; standard: 1297.9 ± 1278.7 fibers; p < 0.01; Fig. 4), fewer aberrant tracts (nTMS: 0.33 ± 0.47 aberrant tracts/tracked CST; standard: 0.57 ± 0.5 aberrant tracts/tracked CST; p < 0.001; Fig. 5), and less interobserver variability compared to standard tracking. Interobserver variability

was evaluated and visualized by a Bland–Altman plot ( Fig. 6) [14]. In both modalities, we were not able to show any significant differences between the two measurements of each observer for any examined item (data not shown). Today, the only widely used and applicable method for preoperative functional brain mapping is fMRI. But, as repeatedly shown, fMRI is insufficient for reliable delineation of functional motor areas [6] and [15]. We moreover confirmed the discrepancy between metabolic and electrophysiological (i.e., true functional) mapping (Fig. 3). Especially in cases when tumors with pathologic vasculature compromise the central region, mapping of the primary motor cortex by metabolic measures was demonstrated to be an unreliable method [15], Bay 11-7085 [16], [17] and [18]. Moreover, metabolically activated brain parenchyma does not have to be essential for motor function. Another disadvantage of fMRI is its frequent affection by the patient’s cooperation or claustrophobia as confirmed in our work. Taking standard deviation into account, spatial deviation of DCS and nTMS ranges within the calculated accuracy of the used nTMS system (eXimia 3.2, Nexstim, Helsinki, Finland), which is 5.73 mm [19]. Such precision was already reported in previous reports on nTMS accuracy stating that a spatial resolution of 5 mm is obtainable [20] and [21].

Furthermore, in the month following the closure the fleet moved

back into the area and reported higher catch rates on floating objects than usual for December (15.8 versus 11.0 t fishing day−1 for the same period in 2008–2011; IOTC data). There is insufficient data available to evaluate the effect of this closure in terms of a reduction in bycatch, although the closure area is a hotspot for bycatch of silky sharks [38]. The displacement of effort around the boundaries of closed areas, often termed ‘fishing the line’, is a common harvesting tactic in many fisheries (e.g. [39] and [40]) and in this instance the purse seine fleet could still access much of the seasonal fishing ground. As such the closure appeared to simply displace the issues associated with FAD fishing. In order to produce meaningful reductions in the catches of juvenile

yellowfin R428 and bigeye tunas using an area closure, it would probably be necessary to implement closures considerably larger (and longer) than those that have been implemented selleck inhibitor to date [41]. The creation of a massive closure in the main FAD fishing region is likely to have a disproportionate effect on catches, as it is unlikely that the fleet would be able to recoup its losses through the reallocation of effort elsewhere due to the relatively poor fishing in other regions during this season. Whilst this conservation measure would be expected to reduce overall catches of small yellowfin and bigeye tunas, it would also result in a significant reduction in catches of skipjack tuna. This loss in catches of what is currently a healthy stock would probably be an unacceptable penalty to the purse seine industry and would also have a major impact on the processing industry in Indian Ocean states, realistically limiting the possibility of such a dramatic conservation measure ever being adopted by the IOTC. The known location of FADs is an important information in determining where

a skipper will choose to fish and in general a larger number of monitored FADs improves both search efficiency and the fishing capacity [2]. A limit on the number of deployed 3-mercaptopyruvate sulfurtransferase or monitored FADs would thus curb search efficiency and decrease (or maintain, depending on where limits are set) the total number of sets made, although it is important to note the distinction between the number of FADs deployed and the number monitored; the former is relevant to modification of the pelagic habitat (and issues related to their effect on tuna biology) whereas the latter is relevant to fishing capacity and efficiency. A challenge for implementing both the measures is setting an appropriate limit without a well defined reference point, which is yet to be calculated by the IOTC.

Após 15 meses de seguimento, permanece assintomática e com níveis indetectáveis GW-572016 mw de β‐HCG. A necropsia evidenciou um feto de 155 g, sexo feminino, sem malformações aparentes, com órgãos tópicos e arquitetura histológica adequada. O feto apresentava, entretanto, hemorragia tímica e em pericárdio e pleura viscerais, assim como conteúdo hemorrágico em lúmen intestinal e brônquico, com quadro morfológico que favorecia o óbito por anóxia aguda (Figura 1, Figura 2 and Figura 3). A avaliação placentária revelou edema vilositário e pseudoinclusões de trofoblasto, sem outras alterações, o que sugeria

cromossomopatia (fig. 4). A avaliação dos restos ovulares evidenciou vilosidades com hiperplasia do trofoblasto e vesículas, achados compatíveis com mola hidatiforme

completa (fig. 5). O presente relato foi autorizado pela paciente, que assinou um termo de consentimento livre e esclarecido. Após a suspeita clínica e ultrassonográfica, o diagnóstico pré‐natal de GGMC é feito Palbociclib solubility dmso por meio de métodos invasivos, com a determinação do cariótipo fetal. O método de certeza é por estudo citogenético, o qual identifica o cariótipo diploide, sendo os cromossomos de origem paterna.3, 10 and 11 Na impossibilidade do estudo citogenético, o diagnóstico final é feito realizado com a avaliação histopatológica da placenta após o termino da gestação.12 No presente caso, a avaliação dos restos ovulares evidenciou vilosidades com hiperplasia do trofoblasto e vesículas, achados consistentes com mola completa.13 A manutenção da gestação em casos de GGMC tem sido descrita por diversos autores, apesar Montelukast Sodium das altas taxas de resultados obstétricos desfavoráveis.4, 5, 7, 8, 10, 14 and 15 Na conduta conservadora, recomenda‐se seguimento clínico rigoroso, determinação do cariótipo fetal e individualização dos riscos maternos e fetais.1, 6 and 15 Sebire et al.7 analisaram 77 casos de GGMC, com 53 casos (68,8%) de manutenção da gestação; desses, dois (03,8%) evoluíram para pré‐eclâmpsia grave; 23 (43,4%) evoluíram com aborto espontâneo

antes de 24 semanas de gestação; e 28 (52,8%) evoluíram com gestações de 28 semanas ou mais, o que resultou em 20 nascidos vivos (37,7%). Yela et al.,10 em uma revisão de 29 trabalhos, encontraram 159 casos de GGMC; desses, apenas 56 (35%) apresentaram término da gestação com feto vivo. A maioria dessas gestações apresentou complicações, como pré‐eclâmpsia e doença trofoblástica persistente. Nos casos de GGMC é indicado o esvaziamento da cavidade uterina após a resolução da gestação, de preferência por meio de vacuoaspiração, a qual apresenta menor taxa de perfuração uterina.14 No caso de úteros com grande volume, a duração do procedimento pode ser extensa e aumentar a perda sanguínea.14 O material obtido pela curetagem apresenta menor índice de autólise e é mais adequado para a histopatologia.

Examples of viral vector candidate vaccines in clinical development are listed in Table 6.3. Non-pathogenic

bacterial vectors have many features that make them an attractive vaccine platform. Bacterial vectors can be engineered for maximum safety (eg deletion of two or more genes from the same metabolic pathway), and to express large numbers of foreign antigens (Figure 6.5). Two key issues affecting bacterial vaccine vectors are: a) to decide whether the optimal platform should be a bacterial vaccine in its own right or a bacterial vector system to deliver exogenous learn more antigens; and b) to determine whether re-administration of the vector, either with the same or different target antigens, will fail because of the immune response to the bacterial vector vaccine at the time of its initial administration.

Initial assessments of the feasibility of using attenuated bacterial vectors for the delivery of foreign antigens have focused on Salmonella species. Bacterial vaccine vectors for humans, however, have been disappointing so far. It may be necessary to develop unique selleck chemicals bacterial vaccine vectors for delivering exogenous antigens, in which case the vectors can be modified to allow for re-use. For example, if immunity against the vector, which is a major impediment to vaccine re-use, is determined by antibodies against the surface structures of the bacterium (such as lipopolysaccharide [LPS]), the dedicated vaccine vector could be developed to lack expression pentoxifylline of LPS or to express truncated/different forms of LPS to the target, thereby avoiding priming of the immune response and allowing for re-use of the vector and/or vaccine. Some potential options for live, attenuated

bacterial vectors are shown in Table 6.4. DNA vaccines are the result of the discovery in the early 1990s that the gene, rather than the encoded protein, if delivered in an ‘expressible’ form, could induce an immune response (see Chapter 1 – Vaccine evolution). The principle behind DNA vaccines is that the antigenic molecule is produced within the host from the DNA or RNA that is injected, in contrast to more traditional vaccination where the antigen is supplied in the vaccine formulation. The gene(s) for target antigen(s) is/are usually encoded in a circular plasmid expression vector under the control of promoter sequences that direct gene expression in mammalian cells, which is achieved after injection into mammals. The DNA vaccine process can circumvent some of the major issues resulting from recombinant protein administration.

Image enhanced endoscopy is extremely useful to detect non-polypoid neoplasia and is now recommended by the AGA, the British Society for Gastroenterology and the Australian Cancer Council. However, video descriptions of imageenhanced endoscopy

for detection of IBD-related neoplasia are rare. We present several illustrative examples. The detection, diagnosis and treatment of all dysplasia – polypoid and non-polypoid – is important in patients with IBD. Early detection can save lives. The video KU-57788 cost provides important information on the recommended technique to screen for dysplasia in patients with IBD and, more importantly, examples of the difficult to find flat and depressed neoplasms. “

“Migration of fully covered self-expandable metal stents (FCSEMS) remains a significant limitation, especially in benign diseases. The lack of a stricture (leaks, fistulae) can further increase the migration rates of Natural Product Library screening FCSEMS. Hemostatic clips are notoriously poor at securing SEMS in place. We describe the use of an over-the-scope clipping (OTSC) device (Ovesco, Tübingen, Germany) to secure the proximal end of FCSEMS [23mm X 155mm Wallflex stent, Boston Scientific, Natick, MA, (case1) and 18mm x 60mm Niti-S stent, Taewoong, Fludarabine purchase Seoul, Korea, Case 2,3)] to prevent migration. Data was collected prospectively on 3 patients who underwent placement of an OTSC device to secure FCSEMS in place from 8/2012 to 11/12. Case 1: 40 YM developed a

leak 2 weeks after a vertical sleeve gastrectomy, unsuccessfully treated with an OTSC, FCSEMS and PCSEMS, that migrated. Therefore the proximal end of FCSEMS was secured in place with an OTSC for 10 weeks, leading to closure of the leak. The OTSC was easily cut with argon plasma coagulator (APC) and removed with the SEMS. Case 2: 73 YM developed a retrocardiac abscess after an esophagectomy for esophageal adenocarcinoma. After migration of a FCSEMS, he was treated with a naso-sinus drain and a FCSEMS secured in place with an OTSC which has resulted in resolution of the abscess, removal of naso-sinus drain and is pending stent removal in 4 weeks. Case 3: 79 YF developed a high-grade refractory (to dilations) anastomotic stricture 3 months after esophagectomy for esophageal adenocarcinoma .

Total RNA was mRNA purified using OligoTex mRNA extraction beads (Qiaqen) with the resulting purified mRNA being eluted in 40 μl of nuclease free water. All RNA samples were quality checked by gel electrophoresis on a 1.2% TAE agarose gel and by spectrophotometry using a Nanodrop spectrophotometer (LabTech International). Purified mRNA samples from regenerating PCI-32765 research buy arms of O. victoriae were pooled, in equal masses, for 454 sequencing on ¼ of a picotitre plate using the GS-FLX platform (Roche, Maryland, USA) at the DNA Sequencing Facility, Department of Biochemistry, University of Cambridge. The resulting sequence

reads were imported into Geneious (Drummond et al., 2010) for quality trimming and assembly into contiguous sequences (contigs). After quality trimming to a phred quality score equivalent of 20 (1% error chance per base) the remaining sequences were assembled using the assembler included in the Geneious software using the medium–low sensitivity option. Assembled contiguous sequences and singletons > 300 bases in length were imported into the Blast2GO program (Conesa et al., 2005) and compared to the NCBI non-redundant (nr) database using BLASTX with an E-value cut-off value of 1.0 e- 6 to identify transcripts with sequence similarity to known genes. These transcripts were further annotated using Gene Ontology (GO). Mapping of assembled sequence reads to known pathways and pathway map generation

was carried out using the KEGG Automatic Annotation Server (KAAS) with a minimum blast bit score of 60 for each alignment (Moriya et al., 2007). A phylogenetic tree to denote the http://www.selleckchem.com/products/lee011.html grouping of the putative Sox transcripts with known

Sox genes was carried out in Geneious (Drummond et al., 2010) using the Geneious tree builder plugin (Jukes-Cantor genetic distance Coproporphyrinogen III oxidase model , Neighbour-Joining tree building method without an outgroup). All sequence data were submitted to the NCBI SRA (short read archive) with the accession number: SRP013357.1 Assembly of the 454 pyrosequencing reads produced from the mRNA of regenerating arms of O. victoriae produced 18,003 contigs with an average size of 606 bp. There were also 31,947 singletons with an average size of 303 bp, of which 17,015 were > 300 bp in length ( Table 1), however, these were not included in the rest of this study. Of the 18,003 assembled contigs 3340 (19%) showed a blast match against the NCBI non-redundant database with an expected value cut off of 1.0 e− 6 ( Supplemental file 1). The low level of putative annotation was similar to that of pyrosequencing studies in other non-model invertebrate marine species ( Meyer et al., 2009, Clark et al., 2010, Clark et al., 2011 and Craft et al., 2010). In the blast search results 1240 of the 3430 matches (36% of the total) were to transcripts from the purple sea urchin Strongylocentrotus purpuratus ( Supplemental file 1).

Images of the stained cells were obtained using a fluorescent microscope attached to a digital camera. Data are expressed as mean (±standard error of the mean, SEM) and analysed and presented using GraphPad Prism. Groups of two were analysed using Student’s t-test, groups of three or more were analysed using either one-way analysis of variance (ANOVA) with a Dunnets post-hoc test or, if multiple variables were involved, two-way ANOVA with Bonferroni post-hoc test was applied.

“The cuneate nucleus (CN) receives and processes incoming somesthetic input from the primary afferents of the forelimb (Andersen et al., 1962, Andersen VE 822 et al., 1964a and Andersen et al., 1964b) before relaying this information, in part, to the ventral posterior nucleus (VPL) of the thalamus (Alloway and Aaron, 1996, Berkley et al., 1980, Kemplay and Webster, 1989 and Massopust et al., 1985). The organization of CN has been described in monkey (Florence et al., 1989), cat (Nyberg, 1988), raccoon (Rasmusson, 1989), and rat (Beck, 1981, Li et al., 2012, Maslany et al., 1990 and Nord, 1967), and it is generally agreed

that the rostrocaudally oriented CN is partitioned into rostral, middle, and caudal regions (Berkley et al., 1986, Bermejo et al., 2003, Dykes et al., 1982 and Maslany et al., 1992). Recently, the details of the somatotopic organization of CN in rat were elucidated using fine-grain electrophysiological mapping (Li et al., 2012). The middle region was further partitioned into medial, central, and lateral zones. The central zone containing cytochrome oxidase (CO)-stained

clusters, termed barrelettes, was mapped, and the individual labeled clusters were associated with the representation Cell Penetrating Peptide of the glabrous forepaw digits and digit and palmar pads; the medial zone was mapped to the ulnar representation of the wrist, forearm, and upper arm, while the lateral zone was mapped to the radial representation of the wrist, forearm, and upper arm. A lateral tail region was identified that received input primarily from the shoulder, head/neck, and ear. This somatotopy in the forelimb-intact rat provided a useful starting point from which to compare CN reorganization following deafferentation. CN organization and the resulting reorganization in rat have been studied following limb amputation (Crockett et al., 1993 and Lane et al., 1995), dorsal rhizotomy (Sengelaub et al., 1997), and nerve transection (Crockett et al., 1993). Time of deafferentation has varied from embryonic (Killackey and Dawson, 1989 and Rhoades et al., 1993), neonatal (Lane et al., 1995 and Lane et al., 2008), and adult (Sengelaub et al.
