.. Videos were captured with a Sony Mini DV GV-D900 and imported using Macintosh OSX and iMovie. Final Cut Pro HD 4.5 was used to cut and export twenty-four 18-sec segments of speech with beat gesture to .avi movie files. As the segments were selected from 2 h of free-flowing speech with gesture, inclusion or exclusion of gesture type could be controlled by cropping. That is, it was possible to eliminate movements that communicated consistent selleck inhibitor semantic information in the absence of speech by beginning an

18-sec segment Inhibitors,research,lifescience,medical after that gesture had occurred. Thus, the gesture in the final stimuli was tightly linked to speech prosody but did not convey semantic information when viewed without the originally co-occurring speech. As the benefits of segregating gesture into strict categories has recently come under scrutiny (McNeill Inhibitors,research,lifescience,medical 2005), in order to maintain ecological validity, beat gesture (i.e., rhythmic gesture) was not limited to flicks of the hand for the purposes of this study (see Hubbard et al. 2009 for discussion). In

the absence of an established method for determining the direct relationship between speech and gesture timing in Inhibitors,research,lifescience,medical free-flowing speech, we retained 18-sec segments of rhythmic gesture and speech that did not contain highly iconic gestures. A group of eight viewers (who were not subjects in the study) reported that semantic information could not be discerned by viewing the video segments in the absence of speech. Because the 24 speech segments used in our prior study in adults (Hubbard et al. 2009) varied in complexity, a subset of 12 segments was selected for this study based on appropriateness for a younger audience. Inhibitors,research,lifescience,medical Additionally, one 18-sec segment with a still frame of the speaker’s body and six segments of ASL-based movements, consisting of Inhibitors,research,lifescience,medical 65 different signs, were selected. The selected ASL movements were noniconic, and a group of eight viewers (who did not participate in the study) again confirmed that the movements did not elicit semantic information. All participants viewed a total

of 18 videos in a single 6-min 30-sec run. Pseudorandomized video blocks involved six conditions, obtained by crossing Sitaxentan movement type (beat gesture, nonsense hand movement, and still frame) by speech (present or absent). The 12 age-appropriate segments of beat gesture and speech were used in the “beat gesture with speech” condition (as originally recorded) and in the “beat gesture without speech” condition (where the audio was removed; see Fig. 3). The six ASL-based segments were used in the “nonsense hand movement without speech” condition (as originally recorded) and in the “nonsense hand movement with speech” condition (where they were paired with speech from the former 12 segments that were originally accompanied by beat gesture).

A total of 516 men with a serum total prostate-specific antigen (PSA) ≥ 2.5–10 ng/mL

were scheduled for initial prostate biopsy and urine was selleck inhibitor collected after digital rectal examination. PCA3 scores were determined and compared with biopsy outcomes. A total of 207 men (40%) had a positive biopsy and showed significantly higher PCA3 scores than men with a negative biopsy (69.6 ± 73.9 vs 31.0 ± 46.9; P < .0001; median values 50 and 18, respectively). With 35 as cut-off, the PCA3 score Inhibitors,research,lifescience,medical had a sensitivity of 64% and specificity of 76%. The probability of having a positive biopsy was 2.7-fold higher in men with a PCA3 score ≥ 35 (64%) than in men with a score < 35 (24%; P < .0001). A significantly higher PCA3 Inhibitors,research,lifescience,medical score was seen in men with biopsy GS ≥ 7 versus < 7, in patients with positive cores > 33% versus ≤ 33%, and “significant” versus “indolent” PCa according to Epstein criteria. A newly developed nomogram

was presented by Choi and colleagues20 to predict the probability of ECE in localized PCa. In their retrospective study, 446 of 1471 patients with clinically localized PCa Inhibitors,research,lifescience,medical had ECE (30%). Age, PSA, biopsy GS, positive core ratio, and maximum percentage of biopsy tumor were shown to be independent predictors of the presence of ECE (P < .05) by multivariate logistic regression models. The nomogram was internally validated, showed good predictive probability, and may be useful for preoperative identification Inhibitors,research,lifescience,medical of patients with ECE and selection of patients in which nerve sparing radical prostatectomy is oncologically safe and feasible. Loch and associates21 prospectively evaluated PCa in patients with multiple negative systematic random biopsies (SRB). A total of 132 patients with a history of at least 1 series Inhibitors,research,lifescience,medical of negative SRB were assigned to a computerized transrectal ultrasound examination. Cancer-suspicious areas were detected by the system via comparison with known and surgically removed carcinomas of the prostate. Targeted biopsies of areas of similarities with cancer patterns were

performed and GS was assessed. PCa could be detected in 66 of the 132 patients (50%), with 5 having a GS of 5, 25 of 6, 22 of 7, 8 of 8, and 7 of 9. The results of this prospective study show that significant cancer can be found in patients with multiple negative SRBs, as that 71.2% of the 66 men with a positive biopsy had a GS 6 or 7 PCa and 22% had a GS of ≥ 8. Essentially, multiple negative Fossariinae SRBs do not exclude high-grade PCa. The Surgical Approach In a multi-institutional study, Beauval and colleagues22 evaluated the pathologic characteristics of prostate specimen after radical prostatectomy (RP) was performed in low-risk patients eligible for active surveillance (AS). A total of 605 men fulfilled the AS criteria (T1c, PSA < 10 ng/ml, 1 positive core with < 3 mm involved, and GS < 7) and were analyzed with regard to pathologic features and oncological outcome.

This is in contrast to most other

head and neck cancers, which are much less likely to be salvageable if they recur after initial non-surgical treatment. Conservation Laryngeal Surgery Conservation surgery (transoral laser or robotic surgery, or open partial laryngectomy) is an excellent option for many patients with early (T1/2N0) larynx Inhibitors,research,lifescience,medical cancers, offering excellent oncologic control and functional outcomes.18–20 For advanced cancers, the role of conservation surgery is much more limited to cases which are either early T stage, but with http://www.selleckchem.com/products/VX-765.html concurrent cervical metastases, or select small-volume T3 cases. One of the drawbacks with conservation surgery

for advanced laryngeal cancer is the risk of greater functional deficit and higher risk of complications with more extensive resections. For example, resection of one arytenoid cartilage during supracricoid laryngectomy has been shown Inhibitors,research,lifescience,medical to lead to increased risk of aspiration pneumonia, longer time to decannulation of tracheostomy tube, and poorer voice.21–25 Inhibitors,research,lifescience,medical Thus, the functional advantages of conservation surgery over non-surgical treatment may be less clear-cut. Another concern is that, in patients with palpable neck disease, concurrent neck dissection will need to be undertaken with the surgery, and postoperative radiotherapy will in most cases be recommended to optimize regional control. The administration of postoperative radiotherapy may also adversely affect functional outcomes, Inhibitors,research,lifescience,medical although as long as the dose to the larynx is kept at 50 Gy, the adverse impact should be within acceptable limits.26,27 Finally, Inhibitors,research,lifescience,medical in the case of cancers undergoing open partial laryngectomy, patients will need to consent to proceeding to possible immediate total laryngectomy based on intraoperative findings and frozen sections. Total laryngectomy may also need

Electron transport chain to be considered in cases with positive margins at final histology. The risk of positive margins and possible need for total laryngectomy is more likely to be an issue for locally advanced primary tumors than for smaller primary tumors. However, given that many such cases are likely to be also amenable to treatment with radiotherapy or chemoradiotherapy with a reasonable expectation of good outcome, getting patients’ consent for an operation which may end up with total laryngectomy may be a “hard sell.” Nevertheless, for well-selected cases of “intermediate-stage” laryngeal cancer, conservation laryngeal surgery effected either by transoral laser or open partial surgical techniques can offer excellent oncological and functional outcomes.

Meta-analysis of CBT Now that BT is firmly established, several meta-analyses have been carried out. The latest meta-analysis71 included 77 studies with 4651 patients and showed that BT was superior to

SSRI antidepressants as a class. Nevertheless, this difference should be taken with caution as BT is limited by the problem of availability, accessibility, and third-party payment in many countries. CT in OCD The status of CT is still under investigation and there have recently been some new studies published (Table IV).72-79 Inhibitors,research,lifescience,medical To date, the usefulness of CT for OCD has been assessed in 8 controlled studies. Emmelkamp et al72 did not find a superior effect, when adding cognitive modifications Inhibitors,research,lifescience,medical to in vivo exposure. Nevertheless, the design of the experiment, aimed at. teaching the patient, to replace negative thoughts by positive ones. This could have been used as neutralizing thoughts. Emmelkamp et al73 compared CT without exposure to self-managed exposure. Six months after the end of treatment, both groups showed equivalent, reduction in rituals, generalized anxiety,

and social anxiety. Only the cognitive group showed change on the measures of depression. In a study with a more impaired population, Emmelkamp and Beens74 found similar results at a 6-month follow-up. Van Oppen et al75 randomized 71 patients in either Beckian CT or exposure. After 16 sessions, they Inhibitors,research,lifescience,medical found a superiority of cognitive interventions over exposure. Danger schemata were better modified by CT than with exposure. Unfortunately, this study had

no long-term follow-up. A multicentered study (76) compared CT with intensive BT. Sixty-five ambulatory patients with DSM-IV OCD and without major depression were randomized Inhibitors,research,lifescience,medical into two groups for a. 16-week psychological treatment: either CT, or exposure and response prevention, for a 4-week intensive treatment period followed by a maintenance phase of 12 weeks. No medication was prescribed. At week 16, the rates of responders were comparable in the two groups. Depression (bipolar type I) was Inhibitors,research,lifescience,medical significantly more improved in the group that received CT. At weeks 26 and 52, improvement was retained in both groups without a between-group difference. Cognitive measures of obsessions changed equally in the two groups. This study replicated on a larger scale the findings of Emmelkamp and coworkers.73,74 Table VI.

Freeston et al77 presented a study comparing a waiting list with a group treated with CBT.

Jones and Mcnzies78 found that CT was superior to a waiting list at. posttest only.

116 Nevertheless, individual differences in genetics, developmental history, and immediate interpersonal context may contribute to inconsistent effects of neuropeptides on interpersonal functioning. Thus, in addition

to genetic differences, compensatory postsynaptic receptor changes in response to prior cumulative opioid exposure and developmental environment may change the manifestations associated with neuropeptide signaling at any given moment. Interactions between monoamine and neuropeptide signaling modulate #buy INK 128 keyword# impulsive aggression,84,85 but these interactions have not been studied sufficiently to suggest a psychopharmacological strategy for BPD that combines both neurotransmitter systems. Although full opioid agonists and antagonists have not yielded promising clinical results, the effect of partial agonists (eg, buprenorphine) on BPD symptoms has never been studied. Despite specific affinity of many opioid medications on mu receptor binding, kappa opioid receptor signaling Inhibitors,research,lifescience,medical may mediate immediate and cumulative effects of repeated trauma on worsening depression and anxiety.141 Kappa antagonists have recently been Inhibitors,research,lifescience,medical considered as novel antidepressants or anxiolytics in animal models,141-144

which may more accurately reflect affective instability in response to interpersonal stressors and attachment insecurity associated with BPD. Limited psychopharmacological Inhibitors,research,lifescience,medical research exists with respect to effects of neuropeptides other than opioids and oxytocin in BPD. Further research may provide novel psychopharmacologic options. Conclusions Symptoms of BPD include impulsivity, aggression, affective instability, transient psychotic symptoms, and interpersonal dysfunction, occurring as manifestations Inhibitors,research,lifescience,medical of core disturbances in representations of self and other.1-3 This core is associated with complex interactions between genetic risk factors and developmental attachment stressors.14-17 Specific neurobiological effects of these risk

factors in BPD remain ill-defined. Hie most up-to-date evidence suggests that anticonvulsant agents such as topiramate, valproate, 4-Aminobutyrate aminotransferase or lamotrigine, and atypical antipsychotics such as aripiprazole and olanzapine, are most effective in treating BPD. Consistent with their benefits on impulsivity, a recent review recommended anticonvulsants and atypical antipsychotics for decreasing alcohol craving and consumption in BPD patients with comorbid alcoholism. Of the antidepressants, MAOIs and fluvoxamine may offer greater therapeutic benefit, but effects of antidepressants on BPD symptoms are more modest. Antidepressant medications may nevertheless be helpful to treat comorbid mood and anxietydisorders, and they may be more efficacious in treating male BPD patients with prominent impulsive aggression.

9 Enzastaurin supplier HESA-A inhibits the growth of cancer cells in a concentration dependent and selective manner.9 It increases the appetite, and can be considered as an immune-modulator, anti-inflammatory, and anti-viral agent. Although HESA-A shows some clinical effects, its precise biological mechanisms remain unclear. It has been shown that in rabbits under oxidative stress challenges, treatment with HESA-A led to an increase in total

antioxidant and antierythrocytelysis.10 In addition, the hepatoprotective effect of HESA-A against hepatic damage in Inhibitors,research,lifescience,medical rabbits was demonstrated in previous study.8 Since HESA-A revealed considerable effects in the treatment of psoriasis vulgaris, a T cell-mediated inflammatory disorder, it seems that it has immunomodulator

characteristics too.5 Such findings indicate that HESA-A may have antioxidant activity. Inhibitors,research,lifescience,medical Furthermore, the finding that HESA-A is rich in trace elements such as Cu, Mn, Se and Zn, which are involved in enzymatic detoxification and antioxidant systems,10 suggests that HESA-A may possess antioxidative effects. Given such evidences, the present study aimed to test whether or not HESA-A has antioxidant properties. To answer such a question, the cytotoxic effects of hydrogen peroxide (H2O2) on Chinese hamster Inhibitors,research,lifescience,medical ovary (CHO) and human embryonic kidney (HEK293T) cell lines were determined following exposure of the two cell lines to HESA-A by cell proliferation and antioxidant assays. Materials and Methods Cell Culture Inhibitors,research,lifescience,medical The CHO andHEK293T cell lines were obtained from national cell bank of Iran (Pasteur Institute of Iran). The cells were grown in RPMI 1640 medium (Gibco-BRL, Germany) containing 10% heat-inactivated fetal bovine serum (Gibco-BRL, Germany) and 1% penicillin streptomycin solution (10,000 Inhibitors,research,lifescience,medical units of penicillin and 10 mg of streptomycin) in a humidified atmosphere of 5% CO2 at 37 C. The cells were cultured in 25 cm2 cell culture flasks. For experimental purposes,

cells were seeded at a density of 2×104 cells/well in 96-well plates 24 h before any treatment. Then, they were treated with 5-20 mM concentrations of H2O2 for different time lengths. HESA-A compound was diluted in phosphate buffered saline (PBS) and the cells were separately treated with 100-1000 ng/ml of HESA-A for different durations. The below CHO and HEK293T cells were also exposed to various concentrations of HESA-A (100, 200, 300, 500 ng/ml), followed by treatment with different concentrations of H2O2. Controls were maintained under normal condition. Cell Proliferation Assays Cytotoxic effects of HESA-A and H2O2 on CHO and HEK293T cell lines were assessed by 3-(4,5-dimethlthiazol-2-yl)-2,5-diphenyltetrazolium Bromide (MTT). The MTT assay was performed as described previously by Roudkenar et al.

A 70-year-old woman with a history of hypertension presented to our outpatient department complaining of recently developed exertional dyspnea. On physical examination, her blood pressure was 100/70 mmHg and the pulse rate was Inhibitors,research,lifescience,medical 105/min with an irregular rhythm. Auscultation of the lungs revealed bilateral crackles at both lower lung fields, and a faint systolic murmur was noted at the mitral valve area. The electrocardiography showed atrial fibrillation with a rate of 100 beats per minute. A transthoracic echocardiogram revealed diffusely hypokinetic left ventricular wall motion with an ejection fraction of 35-40% and mild aortic valve regurgitation. The left atrium was enlarged and its diameter was 42 mm. Transesophageal Inhibitors,research,lifescience,medical echocardiography was conducted to identify the presence of thrombus before performing electrical cardioversion. This study revealed marked spontaneous echo contrast in the left atrium without any visible thrombus. The LAA had a small tubular shape, and the orifice was narrow with

a diameter of 4.8 mm Inhibitors,research,lifescience,medical (Fig. 1A). Color turbulence across the orifice of the LAA with a peak velocity of more than 100 cm/sec was also noted (Fig. 1B and C). The direct current external cardioversion was performed without any complication and the patient was discharged with maintaining Inhibitors,research,lifescience,medical Selleckchem Rapamycin normal sinus rhythm. Fig. 1 Transesophageal echocardiography of the case 1 revealed a small tubular shaped left atrial appendage with a narrowed orifice, and the maximal diameter of the orifice was only 4.8 mm (A). Doppler examination showed significant flow acceleration across … Case 2 Inhibitors,research,lifescience,medical A 68-year-old

male presented with newly developed palpitation. He had a history of diabetes mellitus, hypertension and coronary artery disease along with a history of coronary artery bypass surgery 16 years ago. On physical examination, his blood pressure was 120/70 mmHg and the heart rate was approximately 140/min. Auscultation of the lung and heart was not remarkable. The electrocardiography showed atrial flutter with 2 Idoxuridine : 1 ventricular conduction. Pharmacological cardioversion was tried first, but this failed. A transthoracic echocardiogram revealed global left ventricular systolic dysfunction with an ejection fraction of 35% and a dilated left atrium. On the transesophageal echocardiography, neither intracardiac thrombus nor spontaneous echo contrast was seen. The diameter of the orifice of the LAA was 3.6 mm, and the body of the LAA showed a long tubular shape (Fig. 2A). The flow was accelerated at the ostium of the LAA with peak velocities of more than 110 cm/sec (Fig. 2B and C). Direct current external cardioversion was successfully performed, and the patient was discharged without any adverse events. Fig.

.. Considering that SOD1 manages the accumulation of reactive species, and oxidative stress has been related to the neurodegenerative process in ALS (Basso et al. 2009), we analyzed the

time course of accumulation of nitrosative reactive species. We analyzed nitrotyrosine levels in gray and white matter of the spinal cord, as nitrosative reactive species have been early detected in the SOD1G93A mice. Besides, high levels of nitrotyrosine activate microglia to initiate synaptic stripping (Moreno-Lopez et al. 2011). The staining with antinitrotyrosine was practically absent in WT spinal cord; however, we observed that nitrotyrosine levels Inhibitors,research,lifescience,medical progressively increase in the gray matter and within the MN soma in SOD1G93A mice, reaching

significantly higher values at 2 months of age (Fig. 7). These data suggested that cholinergic alterations may occur earlier than peripheral neuromuscular detachment and consequently Inhibitors,research,lifescience,medical induced ER stress, but in parallel to the initial accumulation of oxidative reactive species. Panobinostat cost Tdp-43 Inhibitors,research,lifescience,medical Finally, considering that Tdp-43, also linked to ALS etiopathogenesis, is involved in multiple steps of RNA metabolism, including transcription, splicing, or transport of mRNA (Lagier-Tourenne and Cleveland 2010), as well as microRNA metabolism, and it has been recently Inhibitors,research,lifescience,medical shown to target ChAT mRNA as well, (Buratti et al. 2010) we wanted

to analyze its expression at early presymptomatic stages in this mouse model. Tdp-43 was found normally present in both nucleus and cytoplasm of the MNs in WT mice. In contrast, Tdp-43 was markedly overexpressed and accumulated Inhibitors,research,lifescience,medical in the nucleus but barely detected in the cytoplasm of spinal MNs in the SOD1G93A mice already at 1 month of age (Fig. 8). The same pattern was observed at 2 months. In contrast, from the symptomatic stage, by 3 months of age, Tdp-43 levels increased also in the cytoplasm of MNs and in the nucleus of surrounding glial cells within the spinal cord parenchyma. Figure 8 Tdp-43 is markedly accumulated in the MN nucleus of the transgenic SOD1G93A mice. Representative confocal microphotographs of single sections where a MN nucleus is present (DAPI staining in blue) showing ChAT (green) and Tdp-43 (red) immunolabeling, and … In conclusion, both the levels and localization isothipendyl of Tdp-43 in all the spinal MNs are severely affected early in the presymptomatic stage in SOD1G93A mice, and parallels the development of cholinergic dysfunctions. Discussion Synaptic cholinergic dysfunction is a common feature of different neurodegenerative diseases, including ALS, but little is known regarding the possible relationship between ChAT abnormalities and the pathogenesis of MN degeneration.

2009; Chen et al. 2010), HIV-related cognitive impairment (Toro-Nieves et al. 2009), dementia (Gomez Ravetti and Moscato 2008; EGFR phosphorylation Britschgi and Wyss-Coray 2009), multiple sclerosis (De Masi et al. 2009), pain disorders (Slade

et al. 2011; Alexander et al. 2012), and psychiatric disorders, including depression (Simon et al. 2008; Domenici et al. 2010; Arnold et al. 2012). Similarly, the results from this study strongly demonstrate the degree to which immune cell signaling proteins influence neuropsychiatric Inhibitors,research,lifescience,medical function in adults with and without HCV, and they suggest that efforts to develop and investigate novel immunotherapies as treatments for neuropsychiatric symptoms are warranted. As described Inhibitors,research,lifescience,medical above, our results show that BDNF, IL-23, RANTES, TNF-α, and TNFR2 may be of particular relevance to HCV-associated neuropsychiatric symptoms. Like many signaling proteins, these factors have dual roles as immunoregulators and neuromodulators, with the potential to both enhance inflammatory responses as well as adversely impact neuronal functions (e.g., target neurons Inhibitors,research,lifescience,medical for cell death, alter synaptic plasticity, hamper neuronal repair, enhance sensitivity to

pain or other stimuli) when upregulated. Thus, immunotherapies that are designed to simultaneously

“normalize” immunoregulation and Inhibitors,research,lifescience,medical neuromodulation may be particularly effective in treating neuropsychiatric symptoms, especially in individuals with chronic inflammatory conditions or infections such as HCV. Consistent with this approach, neurotransmitter-based antidepressants appear to have Inhibitors,research,lifescience,medical at least indirect anti-inflammatory effects and may partially reverse derangements in relevant inflammatory factors (Maes et al. 2009). Fluoxetine treatment for depression reduces serum IL-6 in patients (Sluzewska et al. 1995), and imipramine, clomipramine, venlafaxine, fluoxetine, sertraline, and trazodone have been shown to reduce unless the IFN-gamma/IL-10 ratio of human blood samples (a ratio of proinflammatory/anti-inflammatory drive), consistent with an anti-inflammatory effect (Sluzewska et al. 1995; Maes et al. 1999; Kubera et al. 2001). In addition, nonresponders to selective serotonin reuptake inhibitor medication continue to exhibit elevated IL-6 levels, raising the possibility that response to treatment is linked to a reduction in IL-6 (O’Brien et al. 2007). Thus, immunotherapies that more directly target immune cell signaling may prove efficacious as primary or adjunct treatments for neuropsychiatric disorders.

In contrast,

patients whose colorectal cancer exhibited high Bax expression had a worse outcome when they received 5-FU based treatment, indicating the treatment might be detrimental. Of note, the study showed that expression levels of Bcl-2 and p53 had no predictive value on survival in colorectal cancer patients with or without chemotherapy. This study was performed on archival tissues from 56 patients that received 1 of 6 different chemotherapy regimens after surgery and 56 patients that received surgery alone for stages I-IV colorectal cancer. Additionally patients that died due to other causes Inhibitors,research,lifescience,medical were excluded thus lowering the number of patients in the final analysis. Previous studies Inhibitors,research,lifescience,medical evaluating the prognostic and predictive value of Bax in different cancers have shown conflicting results. In patients with breast cancer, although reduced expression of Bax is also found to be associated with a shorter survival, in contrast to the study by Katkoori VR et al, a decreased response to chemotherapy Inhibitors,research,lifescience,medical is noted (6). In patients with ovarian cancer, overexpression of Bax is associated with significant higher percentage of complete remission after chemotherapy and the survival is also selleck compound prolonged (7). In patients with diffuse aggressive non-Hodgkin’s lymphoma,

low expression of Bax seemingly is associated with a lower survival (8). In patients with hepatic metastases of colorectal cancer, low Bax expression is noted to be an independent negative prognostic marker (9). Apparently, more studies are needed to elucidate the role of Bax as prognostic/predictive markers in various cancers. For decades, clinical decisions on adjuvant Inhibitors,research,lifescience,medical therapy have been determined by the TNM staging system and conventional clinicopathologic factors. Apparently, current therapeutic decision remains suboptimal. With appropriate biomarkers, patients with locally confined cancers who are at low risk

Inhibitors,research,lifescience,medical of recurrence/metastasis could be spared from the toxicity of systemic treatment. In contrast, patients with early-staged cancer at high risk of recurrence/metastasis could be benefited from known effective treatment. With Thiamine-diphosphate kinase advances in basic, translational and clinical research, it is believed that validated clinical biomarkers will become a new standard as part of more accurate prognostic systems and form better predictors of response to specific therapies. Efforts are needed to identify predictive markers so that therapeutic decisions may be made with greater precision. Footnotes No potential conflict of interest.
The advent of the total mesorectal excision (TME), which utilizes sharp dissection through a plane between the visceral and parietal layers of the pelvic fascia to excise the tumor and mesorectum en bloc, has dramatically improved local control following surgery (5).
