The primate chair also comprises two independent sliding doors at the front, allowing execution of manual dexterity tasks with both hands, separately or simultaneously (Schmidlin et al. 2011). Each experimental session was recorded with one to three digital video signaling pathway cameras, depending on the task (drawer, tube, and bimanual board tasks with one camera; modified Brinkman board task with three cameras; Schmidlin et al. 2011).

The duration of a typical daily behavioral session was about 60 min and the experiments were conducted with background Inhibitors,research,lifescience,medical music to cover possible disturbing, external noise. At the end of the session, the animals received their daily ration of food, composed of cereals, fruits, and Inhibitors,research,lifescience,medical vegetables, in addition to the rewards (food pellets) received during the tests. Human subjects The human subjects were 20 persons

(students) aged between 18 and 30 years old. The human experiments were conducted in the context of practical courses for students at the University of Fribourg and the subjects gave their full consent to the experimental protocol. They agreed that the data may be used anonymously for the present study. The human subjects first declared Inhibitors,research,lifescience,medical themselves either as left- or as right-handers and it corresponded to the hand they used to write. Based on this initial self-declaration, there were ten left-handers (six men and four women) and ten right-handers (four men and six women). Inhibitors,research,lifescience,medical The size of each of these two groups (n = 10) was chosen as to approximately match the group size of monkeys (n = 8). Given the human population bias for right-hand preference (about 90%), self-declared left-handers were deliberately recruited, thanks to a large pool of students available Inhibitors,research,lifescience,medical on the campus. It is expected that the self-declared left-handers are less lateralized than the self-declared right-handers. Each human subject was enrolled in a single behavioral session (lasting about

60–90 min) and he/she executed three manual dexterity tasks, before responding to the handedness questionnaire at the end of the session. The set-ups for the three manual dexterity tasks were positioned on a table and the behavioral session was recorded with a digital video camera. The subjects began below with the modified Brinkman board task, followed by the bimanual board task, and finally, the tube task. Before the beginning of the tests, the subjects sat on a chair in the middle and in front of the experimental table. They had to adjust the height of the chair to feel comfortable. Behavioral tasks The assessment of handedness was based on a palette of behavioral manual dexterity tasks, in which macaque monkeys (n = 8) and human subjects (n = 20) were enrolled.

A total of 606 men were randomized in this phase III study to receive tadalafil, 2.5 mg (n = 198), or tadalafil, 5 mg (n = 208), or placebo (n = 200). Results showed significant improvements in International Index of Erectile Function (IIEF)-EF domain scores in both tadalafil groups as compared with placebo (least squares mean

change: placebo, 1.8; tadalafil, 2.5 mg, 5.2; tadalafil, 5 mg, 6.5; both P < .001). Patients treated Inhibitors,research,lifescience,medical with tadalafil, 5 mg, showed significant improvement in total IPSS, whereas no significant improvement was seen in the placebo and the tadalafil groups (tadalafil, 5 mg, −6.1, P < .001; placebo, −3.8; tadalafil, 2.5, mg, −4.6, P = .18). Once-daily 5-mg tadalafil for 12 weeks resulted in statistically significant improvements in IIEF-EF and total IPSS, hence, demonstrated efficacy in the treatment of men with both BPH-LUTS and ED. The reduction in volume of the prostate and the decrease of urethral obstruction are key principles in the management of BPH with 5ARIs. ED, decreased

libido, and decreased ejaculate volume are common side effects seen Inhibitors,research,lifescience,medical in patients treated with these agents. Inhibitors,research,lifescience,medical Zhao and colleagues5 investigated the potential role of 5ARIs in the induction of fibrosis of the prostate via western blotting and enzyme-linked immunosorbent assay in resected prostatic tissue. A total of 20 patients, who underwent TURP for moderate-to-severe LUTS, were included in the study. Ten patients received α-blockers alone and 10 patients received 5ARIs plus α-blockers, for at least 1 year prior to surgery. Results showed

that Inhibitors,research,lifescience,medical three isoforms of nitric oxide synthase (NOS) were overexpressed in the 5ARI group and the expression of transforming growth factor (TGF)-β1, TGF-β2, and p-smad2/3 increased about two-fold as compared with the control group. In conclusion, the group demonstrated that the NOS overexpression may be of importance Inhibitors,research,lifescience,medical in smooth muscle relaxation and therefore improvement of symptoms. However, patients treated with 5ARI may be at higher risk of fibrosis of the prostate due to excessive TGF-β signaling. Resection for BPH An interesting contribution concerning safety in the operating room was made by Undre and colleagues.6 In their study, 20 cases in a www.selleckchem.com/products/R788(Fostamatinib-disodium).html urology operating room were observed in real time however by a psychologist and a surgeon. A validated tool was used by the psychologist to assess interruptions in type (related to communication, equipment, and others) and severity (on a 1 to 9 scale). The task checklist of the Observational Teamwork Assessment for Surgery tool was used by the surgeon to assess safety. A total of 137 interruptions were observed during the cases (85 communication related and 52 others). The operating room teams were affected by a median of six interruptions per hour (range, 2–14). Results showed that communication interruptions generated by surgeons and external visitors were most disruptive.

2013). In the present study, we found that in a normal, healthy human

nerve, RAGE is expressed in almost 30% of all nerve fibers and that number is higher in pathological states such as peripheral neuropathy. We also found that the expression level of RAGE was higher in neuropathic nerves as compared to the control nerve. Given that the Inhibitors,research,lifescience,medical disease was already established, it is not possible to discern if such expression changes were consequences of local traumatic or toxic events and/or whether those changes might have preceded or occurred concurrently with hyperglycemia-evoked peripheral nerve changes observed in diabetes. With respect to the ligands of RAGE in the nerve tissue, we found that the expression of two of the RAGE ligands, HMGB1 and CML, is also higher in the neuropathic nerves; however, their expression levels varied between the neuropathic specimens and controls. While the level of HMGB1 was similar in both idiopathic and diabetic neuropathic nerve, CML level was significantly different between the neuropathic

Inhibitors,research,lifescience,medical specimens. The observed differences might be explained by the fact that following injury, HMGB1 is not only secreted by immune cells Inhibitors,research,lifescience,medical but by neurons as well, thus potentially promoting nerve repair by enhancing axonal sprouting and outgrowth (Lotze and Tracey 2005; Tian et al. 2009). Further, its expression might be unaffected by secondary, hyperglycemic, conditions observed in the diabetic peripheral neuropathy (Faraco et Inhibitors,research,lifescience,medical al. 2007; Shibasaki et al. 2010; Feldman et al. 2012; Juranek et al. 2013). In addition, it has been shown in vitro that blocking RAGE inhibits HMGB1-mediated neuronal development (Hori et al. 1995) indicating that RAGE-HMGB1 interaction might be crucial for repair mechanisms

in the neuropathic nerve. On the contrary, CML is thought to be one of the key molecules in the inflammatory, RAGE-NF-κB-dependent pathway in diabetes, but also, independently from RAGE, it plays an important role in cumulative oxidative stress-induced Inhibitors,research,lifescience,medical neuronal changes, (Haslbeck et al. 2007), contributing to the pathogenesis of neuropathy. Extensive study of CML expression in different types of peripheral neuropathies (Haslbeck et al. 2007) revealed that increased oxidative stress and/or CML-RAGE-NF-κB-activated pathway likely plays a role in diabetes, vitamin B12 deficiency related MTMR9 and chronic inflammatory demyelinating peripheral neuropathy, however, the authors did not observe Apitolisib cost either RAGE or CML increase in the idiopathic neuropathy. This discrepancy might be explained by the fact that the term “idiopathic neuropathy” comprises many different, unrelated, neuropathies caused by multiple factors and cannot be treated as one disease entity. Finally, we found that the expression of mDia1, a cytoplasmic actin-binding protein, described for the first time as an intracellular RAGE ligand in 2008 (Hudson et al.

Hartog calls this regime of historicity “presentism” and defines it as an invasion of the present into the realms of the past and future. For instance, Hartog notes that the conception of the past as a bygone time has recently been replaced by that of memory, which revitalizes in the present what would hitherto have been considered as dead or obsolete. Memory thus

appears as a “presentist Inhibitors,research,lifescience,medical instrument,” allowing for a “presentist use of the past.” Hartog also points to the importance given recently to the notion of heritage, which makes traces of the past necessary components of current individual and collective identities. As for the extension of the present into the future, the historian notes that our societies conceive of the time to come as a source of uncertainty and anguish. Inhibitors,research,lifescience,medical The future must be prepared now, in the present, in order to prevent potential environmental, political, health, and other catastrophes from occurring. According to Hartog, this is evident in the emergence of the principle of responsibility and the precautionary principle, which

state, respectively, that the living are responsible for handing over to future generations a world in which Inhibitors,research,lifescience,medical life will be decent, and that an action should not be Selleck Idarubicin undertaken if it is deemed to have serious potential consequences, notably in the long run. For the French historian, presentism differs significantly from previous temporal orders, namely futurism, eschatologism, Inhibitors,research,lifescience,medical and pastism (mentioned here in reverse chronological order). Futurism, which Hartog dates roughly between the French revolution (1789) and the fall of the Berlin Wall (1989), emphasized the present as a step toward the Inhibitors,research,lifescience,medical future; time was seen as a movement of uninterrupted improvement, with an ever-increasing efficiency of technologies and a continuous economic growth. It was an era marked by the idea

of progress and an orientation toward the future. Before the advent of futurism, eschatologism was the dominant temporal order, according to Hartog. It envisaged time above all as a process of salvation. In his theory, the resurrection of Christ marks the beginning of the process—being a fixed, past event, it acts as one of the delimitations of time—which needs to be completed, and this supposedly occurs through the second coming of Christ (parousia), or Judgement Day—representing the other delimitation SPTLC1 of time. In this regime of historicity, the present acts as an in-between stage; it is simultaneously a time of reminiscence about salvation and a time for the expectation of eternal life. “Past, present and future are articulated on the backdrop of eternity,” as Hartog writes (p 75). Finally, pastism, which the historian dates back to ancient times, conceived of the present as the reverberation of a mythical past.

e., ≤$15,000) was negatively Bardoxolone concentration associated with antidepressant use, but the level of education, private/veterans insurance or MAP coverage, family support, and disability

score were not significant factors. Of need factors, the HAMD score and pain medication intake were not significantly associated with antidepressant use but antianxiety medication intake was a significant factor. Table 3 Correlates of antidepressant intake: binary logistic regression results (N = 162) The OLS regression results (not shown in Table 3) found that the perceived effectiveness Inhibitors,research,lifescience,medical of antidepressants was negatively associated with being aged 70 or older (β = −0.321, t = −2.210, P = 0.031) and the HAMD score (β = −0.299, t = −2.320, P = 0.024). Sex and race/ethnicity were not significant correlates. However, caution is required in interpreting the results, given the small sample size. Discussion The study found that about half of the low-income, depressed, homebound older-adult participants were taking antidepressant medications. All predisposing factors (sex, age, Inhibitors,research,lifescience,medical and race/ethnicity) were Inhibitors,research,lifescience,medical significantly associated with the likelihood of antidepressant use, supporting H1a. Of the enabling factors, only income was a significant correlate. Of the need factors, severity of current depressive symptoms was not significantly

associated with antidepressant intake, partly because the study included only depressed participants. The cross-sectional data did not allow us to examine the severity of depressive symptoms prior to antidepressant use either. However, the finding that self-reported use of antianxiety

medication was positively associated with self-reported antidepressant use suggests the importance Inhibitors,research,lifescience,medical of comorbid anxiety and depression and associated symptom severity as a need factor. Thus, the logistic regression results did not support H1c and only partially supported H1b and H1d. The hypothesis regarding the factors associated with the participants’ perception of effectiveness of antidepressants was also partially supported Inhibitors,research,lifescience,medical as it was negatively associated with older age (70+) and higher HAMD scores, but it was not significantly associated with gender why and race/ethnicity. The negative relationship between age and antidepressant use appears to suggest an age cohort effect, with those aged 70 or older having a more negative predisposition toward antidepressant use than those aged 50–59. Based on the study’s finding that those aged 70 or older were also less likely to perceive their medications to be effective, some individuals in this age group may have stopped taking antidepressants. PCPs may also be reluctant to prescribe antidepressants to older patients, especially those with multiple medical conditions (Bruce et al. 2002; Ayalon et al. 2010). The finding may also reflect low-income, depressed, homebound older adults’ preference for nonpharmacological over pharmacological treatment.

2009, 2010), and (4) markers reflecting changes in astrocytic and microglial responses in spinal cord and DRG. Existing evidence shows that AM1241 acts as an agonist at the cannabinoid 2 receptor (CB2R) that results in suppression of nociceptive responses (Rahn et al. 2010), and prevents neuropathic and inflammatory pain (Nackley et al. 2004; Beltramo et al. 2006; Rahn et al. 2008), with selectivity demonstrated Inhibitors,research,lifescience,medical not only by utilizing pharmacological CB2R antagonists, but also by examining AM1241 analgesic efficacy in CB2R knockout mice (Ibrahim et al. 2003, 2006). CB2Rs are characterized on microglia

and macrophages in cell culture (Walter et al. 2003; Cabral and Marciano–Cabral 2005; Ehrhart et al. 2005) and in the rodent spinal cord following peripheral nerve damage (Zhang et al. 2003; Romero-Sandoval et al. 2008a) or in transgenic Inhibitors,research,lifescience,medical mice overexpressing the CB2R (Racz et al. 2008b), as well as in the human central nervous system (CNS) under inflammatory diseased conditions (Nunez et al. 2008). Given that AM1241 can act on CB2Rs expressed on spinal Inhibitors,research,lifescience,medical microglia, the potential additional (1) cytokine and (2) p-p38MAPK involvement in AM1241s efficacy in producing spinal anti-inflammatory actions concurrent

with anti-allodynia were examined in these studies. Related to these goals, we examined two methods to analyze immunofluorescent images of spinal cord tissue sections to identify Inhibitors,research,lifescience,medical the most sensitive procedure for detecting and quantifying differences in specific immunoreactive protein markers. In this context, an alternative method that utilizes spectral analysis procedures, demonstrated here, can be advantageous over conventional methods of image analysis. Materials

and Methods Animals A total of 52 pathogen-free adult male Sprague Dawley rats (300–400 g; Harlan Labs, Madison, WI) were used in all experiments. Rats were double housed in a temperature- and light-controlled (12 h light/dark; lights on at 6:00 AM) environment, with standard rodent chow and water available ad libitum. All procedures Inhibitors,research,lifescience,medical were approved by the Institutional Animal Care and Use Committee (IACUC) of the University of New Mexico Health Sciences Center. Drugs The CB2R agonist used in these experiments was (R,S)-(2-iodo-5-nitrophenyl)-(1-[(1-methylpiperidin-2-yl)methyl]-1H-indol-3yl)-methanone CYTH4 (AM1241) from the aminoalkyndole classification (Yao et al. 2006). Water-soluble hydrochloride salt of racemic AM1241 was generously gifted (A. Makriyannis, Center for Drug Discovery, Northeastern University). Initial doses of AM1241 were based on those previously reported for i.v. injection (Beltramo et al. 2006) and pilot studies. A 1000-fold dose range of AM1241, this website dissolved in sterile saline (Hospira Inc, Lake Forest, IL) was tested (10–0.01 μg in 10 μl) or equivolume sterile saline as vehicle.

Both

OFC and check details quetiapine have shown clear superiority over placebo and are reasonable first-choice agents. Of atypical antipsychotics, the data most, strongly support, quetiapine in the treatment of bipolar depression, with widespread effects across the core symptoms of depression, including an ability to reduce suicidal thinking.33 When patients are nonresponsive or only partially responsive to a trial of a single mood stabilizer, considerations include switching to an alternate mood stabilizer/atypical antipsychotic, combining mood Inhibitors,research,lifescience,medical stabilizers/atypical antipsychotics, or augmenting with an agent that may possess clinical, but often less empirical evidence, to support its use. Among mood stabilizers, lithium, lamotrigine, and divalproex should be given initial consideration, while among atypical antipsychotics, only olanzapine and quetiapine are substantiated by trialbased assessments. Of moderately sized, multicenter studies, only lamotrigine24 and modafinil56 Inhibitors,research,lifescience,medical have been

shown to reduce depression more effectively than placebo when administered adjunctively to a mood stabilizer. For all agents, it should be kept, in mind that an adequate trial consists of at Inhibitors,research,lifescience,medical least 6 weeks of treatment. Over the last decade, we clinicians have witnessed tremendous advances in our ability to manage the depressed phase of bipolar disorder. Nevertheless, even with access to the most, novel pharmacological compounds and adherence to research-driven treatment algorithms, bipolar Inhibitors,research,lifescience,medical disorder remains a burdensome and chronic illness. In as much, less than one third of patients who achieve recovery are likely to remain well over 2 years of follow-up.13 These sobering outcomes invite the need for clinical trials seeking to prevent depressive relapse and to explore whether combination treatments provide added efficacy, increased effectiveness, and enhanced recovery. Such trials might employ sequential, adaptive design schemes that incorporate advances

in our understanding of Inhibitors,research,lifescience,medical genomics and the neurobiological underpinnings of bipolar disorder. It is the expectation that the next generation of clinical trials will provide more personalized and predictive treatment options for those who Terminal deoxynucleotidyl transferase suffer from this protean disorder.

The nonvolatile vehicle would

be the PE only or the combination of PE and film forming polymer (FFP). The spray PF-06463922 System was prepared by incorporating FFP and PE into a solvent system. We used ethanol as the volatile vehicle in this study. The drug application system (Wantong Fixed Quantity Valve System Co. Ltd., Suzhou, China) consisted of a 10mL container and an actuator with the actuating volume of 100μL. Formulations were prepared with a series of Inhibitors,research,lifescience,medical batches using different PEs or FFPs according to Table 1. The chosen FFPs were based on the following criteria: drying time, cosmetical attractiveness, and outward stickiness. Table 1 Composition of investigated formulation for excipients screening. 2.4. In Vitro Skin Permeation Experiments We used three animal models for the in vitro experiments. They are

hairless mice, rat, and porcine. The procedure of the skin was as follows; the dorsal skins of hairless mice or rat were excised after sacrifice by cervical dislocation; porcine skins were obtained from young animals Inhibitors,research,lifescience,medical sacrificed at the local slaughter house. Adjacent parts of the same skin were used under different conditions to minimize the skin variability factor. Fresh prepared skins were stored in refrigerator at −20°C without repeatable freeze and thaw cycles. Prior to permeation experiments, skin was thawed and subcutaneous Inhibitors,research,lifescience,medical fat, tissue, and capillaries of skin were carefully removed. The skins were washed with normal saline solution and inspected for the integrity by microscope observation. Any skin that had low uniformity was rejected. Inhibitors,research,lifescience,medical After cutting into pieces, skin was mounted between the donor and receptor compartment of the Franz diffusion cells with

the stratum corneum facing the donor compartment. The permeation area of Franz diffusion cells was 3.14cm2 and a receiver volume was 7.0mL. Phosphate buffer saline (PBS) with PH 7.4 was used as the receiver medium. Assembled diffusion cells in triplicate were placed in a transdermal permeation diffusion instrument and maintained isothermally Inhibitors,research,lifescience,medical at 32°C. The receptor compartment was stirred with a magnetic stirrer at 220rpm. The air bubbles that remained in the receptor cell were carefully removed by gentle tilting of the diffusion cells. After the whole system was maintained at 32°C for 2h, we used micropipette to deliver medroxyprogesterone 100μL drug liquid precisely and uniformly on the skin. Samples (0.3mL) were withdrawn at 2, 4, 6, 12, and 24h for HPLC analysis and were replaced with an equivalent volume. All samples were centrifuged at 17,800×g for 3min and then supernatant was used for analysis. The cumulative amount Q (μg/cm2) of DE permeated through skin was calculated by the following equation: Qn=Cn×V0+∑i=1n−1(Ci×Vi)A, (1) where A is the effective area 3.14cm2, Vo is the volume of receptor cell 7.

Drugs that directly activate the reward PF299804 in vivo system may produce learning that diverts the individual to those behaviors that repeat the drug-induced feelings of reward. An important feature of this form of neuroplasticity is that it is stable and perhaps permanent. The dopamine release caused by a drug of abuse tends to be greater than that of natural rewards, and to continue with repeated exposure rather

than diminish, as is the case with natural, expected rewards2. Thus, the drug experience becomes associated with environmental cues and acquires increasing salience. Individuals who develop this neuroplasticity tend to suffer from a chronic illness with potential for relapse, Inhibitors,research,lifescience,medical even years after the last dose of the drug. Drug-taking then acquires more salience than natural or adaptive behaviors. Evidence of the plasticity that has occurred with the development of addiction

can be demonstrated by brain Inhibitors,research,lifescience,medical imaging studies that show rapid activation (increased blood flow to reward pathways) when drug-related cues are shown to addicts who have been free of drugs for at least a month.3 Even cues so brief that they do not reach consciousness (33 msec) can produce rapid activation.4 During brain reward system activation, the addict reports drug craving. The strength of the craving Inhibitors,research,lifescience,medical is related directly to the amount of endogenous dopamine released in reward structures, as measured by displacement Inhibitors,research,lifescience,medical of labeled raclopride in positron emission tomography (PET) studies.5 More direct studies of the plasticity induced by drugs of addiction can be seen in animal models. Shaham and colleagues have studied the relapse or reinstatement of drug-taking in rats trained to self-administer intravenous cocaine.6 Availability of cocaine

is signaled by a light that the animal then associates with cocaine. After the behavior is well trained, the cocaine can be turned off; thus, pushing the lever no longer provides cocaine. After the extinction process is complete, the animal can be tested for reinstatement by returning it to the Inhibitors,research,lifescience,medical drug-taking environment and giving the light cue. This is considered to be a model of “relapse” in human addicts. The intensity of relapse can be measured mafosfamide by the number of times the light causes the rat to press the bar despite not receiving any cocaine. Eventually, the unrewarded bar pressing stops. It was found that reinstatement occurred when rats were tested 1 week after extinguishing cocaine-seeking, but the reinstatement was significantly greater at 4 weeks, and progressively increased further if the rats were allowed to rest in their cages for up to 6 months before relapse testing. The strengthening of relapse tendency over time has been called “incubation” and is associated with increases in the levels of the growth factor brain-derived neurotrophic factor (BDNF) in the ventral tegmental area and in the nucleus accumbens.

Most patients with esophageal cancer require multi-disciplinary management, with radiation therapy constituting a key component of therapy. In this issue, Jabbour et al. present an excellent review article on the role of radiation therapy in the postoperative management of esophageal cancer (1). The authors must be commended for this thorough, evidence-based review article. Inhibitors,research,lifescience,medical In addition to discussing postoperative radiotherapy for esophageal cancer, the authors also discuss the roles of definitive chemoradiation, preoperative chemoradiation, preoperative

chemotherapy and postoperative chemotherapy. As Jabbour et al. have discussed, multiple randomized trials have evaluated whether preoperative chemoradiation improves outcomes compared to surgery alone for esophageal cancer (1). In the Cancer and Leukemia Group B (CALGB) 9781 trial, patients with T1-T3

esophageal squamous cell carcinoma or adenocarcinoma were randomized to receive either surgery alone, or surgery with preoperative chemoradiation, Inhibitors,research,lifescience,medical with a dose of 50.4 Gy in 1.8 Gy check details fractions, Inhibitors,research,lifescience,medical along with concurrent cisplatin and 5-fluorouracil (2). Patients in the preoperative chemoradiation arm had a median survival of 4.5 years and a 5-year survival of 39%, while patients in the surgery alone arm had a median survival of 1.8 years and a 5-year survival of 16% (P=0.002). However, it should be noted that this trial had a poor accrual of Inhibitors,research,lifescience,medical only 56 patients, out of a planned accrual of 475 patients. The case for preoperative chemoradiation has been recently bolstered by presentation of results from the CROSS trial from the Netherlands (3). In this phase III trial, 363 patients with T2-3 N0-1 esophageal carcinoma Inhibitors,research,lifescience,medical were randomized to receive either surgery alone, or surgery with preoperative chemoradiation, with a dose of 41.4 Gy in 1.8 Gy

fractions, with concurrent paclitaxel (50 mg/m2) and carboplatin (AUC 2). Of the enrolled patients, 75% had adenocarcinoma, 24% had squamous cell carcinoma, and 1% had other histologies. Overall survival was significantly improved in the preoperative chemoradiation Non-specific serine/threonine protein kinase arm (P=0.01). Patients in the preoperative chemoradiation arm had a median survival of 49 months and a 3-year survival of 59%, whereas patients in the surgery alone arm had a median survival of 26 months and a 3-year survival of 48%. Formal publication of this trial is being eagerly awaited. Nevertheless, this trial has the potential of being regarded as a landmark study, which will pave the way for establishing preoperative chemoradiation as a standard of care for resectable esophageal cancer. Jabbour et al. have included a detailed discussion on the relative advantages and disadvantages of preoperative and postoperative therapy. An important advantage of preoperative chemoradiation is that smaller fields can be used in most cases.
