Using global statistics on the scalp electric fields, we measured the performance difference (remembered–forgotten), that is, SMEs, computing the average mean activity in the time window from −2 to −1 sec. Paired TANOVAs for each condition yielded a marginal effect in the stay condition (P = 0.052) and no effect in the switch condition (P = 0.196). The same procedure Inhibitors,research,lifescience,medical was applied in the time interval from −1 to −0 sec and here again, we found an opposite pattern, this means a significant effect in the switch condition (P = 0.009) but no significant effect in the stay condition (P = 0.348). The Vandetanib clinical spatial distribution of these effects was further displayed and explored on the scalp level with t-maps as shown

in Figure ​Figure44. Hence, these results suggest that the processing of subsequently Inhibitors,research,lifescience,medical remembered and forgotten words might differ in location and/or relative contribution of the brain structures across the entire epoch with an opposite pattern in the two time windows, showing the emergence of the SME in both conditions but in different time frames. Differences in amplitude independent of topography were analyzed based on the differences in GFP (see Figs. ​Figs.4,4, ​,5).5). In the −2 to −1 sec window, we observed that forgotten words were associated with a higher GFP than remembered words both in the stay condition

(t(20) = −4.47, P < Inhibitors,research,lifescience,medical 0.001) and in the switch condition (t(20) = −4.88, P < 0.001). In the interval between −1 and −0 sec, GFP results were similar, showing an effect in both conditions (t(20) Inhibitors,research,lifescience,medical = −3.54, P = 0.002) and (t(20) = −4.21, P < 0.001) in the stay and switch conditions, respectively. The significant t values were in all cases negative, indicating higher prestimulus activity for the subsequently forgotten versus the subsequently remembered items as previously shown

(Padovani et al. 2011). Figure 5 T-test differences in global field power (GFP): **: P < 0.01 and ***: P < 0.001. Note that the standard deviations of the mean values shown do not correspond Inhibitors,research,lifescience,medical to the standard deviation employed for the paired t-tests. (A) Time interval ... A post hoc TANOVA was computed to assess the possible interactions of a third factor, the instruction type (emotional, semantic) with the two factors already considered in the previous analyses, namely condition Entinostat and performance. To compute these analyses, we have considered the data of only 14 subjects with a minimum number of 10 trials for each condition. The results showed neither triple interaction nor other effects, but only a main effect near to significance (P = 0.06) for condition and performance in the time window from −1 to 0 sec. This finding, taken with caution, provides an indication that collapsing the trial activity across instruction types was correct and confirms the validity of our analyses, although it suffers from a loss of sufficient trials.

According to the calculation, the δA/δT value for all three dosing schemes was approximately 2mg/hr. The higher exposures observed from the longer

dosing interval were attributed to the increased absorption time (Figure 5). Figure 3 Compound 1 50mg/Kg X3 tandem dose (2.5hr interval) Idelalisib CLL Predicted versus observed exposure. Figure 4 Compound 1 50mg/Kg X3 tandem dose (1, 1.5, and 2.5hrs interval) exposure comparison. Figure 5 The 50mg/kg X3 Tandem Dose Wagner-Nelson Plot (Cabozantinib cost presented as mean values). For the 100mg/Kg tandem dosing groups, similar impacts were observed when the dose interval changed. In general, the Inhibitors,research,lifescience,medical shortest dosing interval (1hr) gave the lowest exposures. Again, it is hypothesized with such a short interval, drug “overlapped” from dose to dose which caused the nonabsorbable portion to increase thereby reducing the exposure Inhibitors,research,lifescience,medical (similar to an s.i.d. dose). Better drug delivery efficiency was achieved when the dose interval increased to 1.5 and 2.5hrs. The Cmax and AUC (Tables ​(Tables44 and ​and5)5) obtained from both dosing schemes Inhibitors,research,lifescience,medical are comparable and well exceed the values from the s.i.d. dose (Table 2 300mg/kg). This suggests that for this dose (100mg/Kg X3) 1.5hrs may be sufficient to separate two doses as well. However, it is worth noticing that the variability

of data obtained from the 1.5hr interval is higher than that of the 2.5hr interval. This suggests that the 1.5hr interval

may not be ideal for higher doses as the risk of drug overlap in the GI is higher and may have contributed to the higher variability in exposures. The simulated exposure (2.5hrs interval) versus the obtained exposure for Inhibitors,research,lifescience,medical the 100mg/kg X3 tandem dose is presented in Figure Inhibitors,research,lifescience,medical 6, and the AUC/Dose (for 2.5hr interval) was calculated to be 1.03±0.05μM*hr/mg/kg. Based on the linear model and exposures obtained from the 1.5 and 2.5hr intervals, a noticeably increased beta phase half-life was observed from the tandem doses versus the predicted curve. It is possible that via accumulation the drug exposure has reached the nonlinear range (saturated the CL), and therefore a linear PK model underpredicts the beta phase half-life. Carfilzomib A Wagner-Nelson plot (see Section 2) was used to calculate drug absorbed and to assess the absorption as a function of time and is presented as Figure 7. Again, the higher exposures observed from the longer dosing interval were attributed to increased absorption time. Figure 6 The 100mg/kg X3 Tandem Dose Predicted (2.5hr) versus Obtained Exposures from 1, 1.5, and 2.5hrs interval. Figure 7 The 100mg/kg X3 Tandem Dose Wagner-Nelson Plot (presented as mean values). Table 4 Tandem dose scheme AUC comparison (μM*hr). Table 5 Tandem dose scheme average Cmax comparison (μM). For the 200mg/Kg tandem dosing groups, a much bigger impact was observed when dose interval changed.

1 However, surgical replacement of selleck catalog aortic valves in the 1960s altered the paradigm for management of this disease and led

to nearly normal survival for postoperative patients after aortic valve replacement. By far, the most common etiology of aortic stenosis in patients older than 75 years is degenerative calcification of the valve.2 However, the major caveat of an open surgical approach is that to benefit from surgical aortic valve replacement, the patient must first survive the surgery. The issue of perioperative mortality and Inhibitors,research,lifescience,medical morbidity is particularly important in patients with degenerative aortic stenosis, as the frequency of the disease is age-dependent, ranging from about 2.4%, in patients between the ages of 75 and 84, to 7%, in men aged 85 or older.3 Obviously, the risk associated with open-heart surgery is higher in these patients than in those who are younger.

Consequently, a substantial proportion of elderly patients with degenerative aortic stenosis do not undergo surgical Inhibitors,research,lifescience,medical Inhibitors,research,lifescience,medical valve replacement The advent of balloon aortic valvuloplasty in the 1980s led to novel thinking about catheter-based management of aortic valve disease. Originally derived from balloon dilation of the pulmonic valve in pediatric patients, this technique initially offered moderate symptom relief in patients who were not candidates for surgery. However, the results selleckbio proved to be short lived, subsequent survival was dismal (< 25% at three years),4 and enthusiasm for the procedure waned. The advent of percutaneous valve Inhibitors,research,lifescience,medical replacement by Cribier5 — inspired by pulmonic valve implantations in late survivors of Tetralogy of Fallot corrections and first performed in

a 57-year-old patient with a congenitally Inhibitors,research,lifescience,medical bicuspid aortic valve — led to the gradual development of more user-friendly valves and broader application of their use. In 2010, the PARTNER cohort B study treated 358 otherwise inoperable patients suffering from critical aortic stenosis with transcatheter valve replacement (TAVR). Compared with medical therapy, TAVR saved one life at the end of a year for every five patients treated. By the end of the second year, the number needed to treat had fallen to four. These findings ignited enthusiasm for this procedure and assured it of a place in the mainstream of modern cardiac interventions.6 One valve is currently approved in the United States Cilengitide for use in this population (Edwards SAPIEN), another valve is undergoing clinical trials (Medtronic CoreValve®), and two more are about to enter clinical trials. In Europe, three different valves are approved for clinical use. Investigators and regulatory authorities are currently evaluating expansion of the TAVR population to include patients in lower-risk categories who might otherwise undergo surgical aortic valve replacement albeit at higher-than-average risk.

31 Second, hoarding has been linked to poorer health status. Individuals who hoard are very likely to be overweight or obese and suffer from a severe medical condition.31

Third, several clinical and community studies have reported a low rate of marriage among compulsive hoarders.14,29,32,33 Those who are married or selleck inhibitor cohabitating tend to have a lower degree of hoarding severity31 Fourth, hoarding is associated with high rates of family frustration. Family members who cohabit with hoarders report being embarrassed about Inhibitors,research,lifescience,medical the condition of their home, arguing about the clutter, and feeling rejection and hostility toward the hoarder.31 In summary, emergent research suggests that the prevalence of compulsive Inhibitors,research,lifescience,medical hoarding ranges from 2% to 5%, and men may be more likely to hoard than women. In most cases, hoarding is a chronic disorder. Although some people may experience a gradual rise in symptoms throughout their lifetime, others

may develop hoarding symptoms quite quickly after a stressful life event. Men and women who hoard may experience different cooccurring Inhibitors,research,lifescience,medical disorders, yet both genders are likely to experience a substantial amount of burden associated with their hoarding. Neuropsychological impairment Neuropsychological research into hoarding did not begin to build until the last decade. The initial clues that hoarding was related to frontal-lobe dysfunction came from case reports of pathological collecting and saving that began after a brain injury, typically along with other changes in personality and social functioning.34-36 In the last decade, two papers presented findings suggesting that hoarding is the result of frontal-lobe lesions. In the first report, Hahm and colleagues36 described the case of a 46-year-old Korean man who began Inhibitors,research,lifescience,medical unusual collecting Inhibitors,research,lifescience,medical behavior after he suffered an injury to his left ventromedial prefrontal cortex and caudate. This man had difficulty with social decisionmaking and judgment processes. In the second report, Anderson et al37 examined compulsive hoarding behavior within a sample

of 86 patients with focal lesions, and found that 13 of these participants exhibited abnormal collecting behavior. Magnetic selleck bio resonance imaging Cilengitide (MRI) showed that all 13 individuals with hoarding symptoms had damage to the mesial frontal region of the brain, including the right polar sector and anterior cingulate. If excessive collecting and saving behaviors can begin after brain injury, individuals who hoard in the absence of lesions may possess similar deficits in neuropsychological functioning or impaired self-regulation that contribute to compulsive hoarding symptoms. Self-report and laboratory studies of neuropsychological functioning in hoarding have highlighted potential areas of subtle impairment. In a study by Hartl et al, hoarding patients reported increased symptoms of attention deficit-hyperactivity disorder (ADHD).

47 Drugs antagonizing the 5-HT2A/C receptor increase SWS, whereas 5-HT2A/C agonists have the opposite effect.48 Spectral analysis of selleck chemical Paclitaxel non-REM sleep shows a huge increase in slow wave activity with compounds blocking 5-HT2A/C transmission.49, 50 Although some antidepressant and antipsychotic drugs display this Inhibitors,research,lifescience,medical 5-HT2A/C antagonist profile and indeed have been shown to increase SWS,51, 52 up to now there is no drug marketed for sleep disorder that enhances SWS in a sustained manner. In contrast, chronic benzodiazepine administration has been shown to decrease SWS.53 New nonbenzodiazepine hypnotics acting at. the GABAA receptor, such as zopiclone,

Zolpidem, and zaleplon, have a more favorable profile in terms of sleep architecture, although none of them has demonstrated sustained SWS enrichment

after repeated administration.54 In this regard, 5-HT2A/C receptor antagonists could thus be of great interest, for alleviating age-related Inhibitors,research,lifescience,medical sleep disturbances and for ameliorating psychomotor and cognitive functions by restoring deep SWS, particularly in elderly insomniacs. There is preliminary evidence to suggest that repeated administration of ritanserin 5 mg (a 5-HT2A/C receptor antagonist) in middle-aged poor sleepers decreases the Inhibitors,research,lifescience,medical frequencies of awakening and improves subjective quality of sleep55 and increases subjective alertness Inhibitors,research,lifescience,medical in narcoleptic patients56 and in young healthy volunteers performing a driving test.57 Furthermore, in young healthy subjects, Gronfier et al58 found that, the SWS enrichment induced by the acute administration of ritanserin 5 mg is positively correlated to the amount of GH secretion, suggesting a common 5-HT2a/c-triggered stimulatory mechanism between GH secretion and delta wave activity. Inhibitors,research,lifescience,medical The question of whether antagonizing

the 5-HT2A or 5-HT2C receptor allows SWS enhancement is still they unresolved. There are some data suggesting that 5-HT2C mediates SWS,59, 60 but Landolt et al49 showed substantial SWS enhancement with SR 46349B, a specific 5-HT2A antagonist. Clozapine, which displays a weaker activity Entinostat for 5HT2A receptors, does not seem to affect, SWS in schizophrenic patients or even tends to diminish it. Olanzapine induces clear-cut, SWS enhancement in healthy subjects61-67; these effects seem to be mediated by 5-HT2C receptors, since allelic differences in the gene coding for this receptor influence SWS responses to olanzapine.63 In summary, compounds antagonizing 5-HT2A/C receptors could be valuable drugs for age -related sleep disturbances. In healthy subjects, studying drug-induced SWS alteration is a particularly useful tool for the development of CNSacting compounds with 5-HT2A/C-blocking properties.

Exploratory behaviors are the acts and postures that allow an animal to gather information about a novel environment (Crusio and Van Abeelen 1986). These behaviors have been further classified into diversive and specific exploration dependent on the actuating Inhibitors,research,lifescience,medical agent (Berlyne 1966). While diversive exploration is driven by a desire to be stimulated and relieve boredom, specific exploration is induced by novelty and may be driven by anxiety-like responses. Specific exploration was initially called the investigatory reflex by Pavlov when he Inhibitors,research,lifescience,medical found that dogs would stop from active behaviors to attend novel stimuli (Pavlov and Anrep 1927). Even though exploratory behaviors are a complex and dynamic response to the novel stimuli, these behaviors are likely to include regular features that depend on properties of the environment.

selleck chem Identifying these physical variables and understanding how they influence exploratory behavior can give significant insights into the mechanisms involved Inhibitors,research,lifescience,medical in behavioral responses to external stimuli. Drosophila melanogaster respond to a novel open-field arena with a high level of initial activity, followed by decay to lower levels of spontaneous activity (Connolly 1967; Meehan and Wilson 1987). In Drosophila, the elevated initial activity has been proposed to represent specific exploration (Liu et al. Inhibitors,research,lifescience,medical 2007). Initial activity scales linearly with the circumference of the selleck chemicals MEK162 circular arena, is independent

of handling prior to placement within the arena, and is genetically separable; mutations Inhibitors,research,lifescience,medical in the kurtz arrestin result specifically in lower levels of initial activity (Liu et al. Anacetrapib 2007). Lastly, visually impaired flies are significantly impaired in the attenuation of initial activity, suggesting that visual information is required for the rapid decay from elevated initial activity to spontaneous activity within the novel open-field arena (Liu et al. 2007). Drosophila species also display strong wall-following behavior in open-field arenas; which has been alternatively interpreted as thigmotaxis (the attraction to the touch of the arena wall) and centrophobicity (center avoidance due to fear) (Gotz and Biesinger 1985; Besson and Martin 2005; Valente et al. 2007). Strong wall-following behavior may be a complex interaction that includes both thigmotactic and centrophobic responses, and in many species may represent a search for safety (Treit and Fundytus 1988; Choleris et al. 2001).

137 Recent evidence indicates that estrogen can produce an antidepressant response in perimenopausal women with major or minor depression.128,129 Antidepressants are clearly effective for dysphoric mood. Although preliminary findings have suggested that the combined use of HRT and serotonergic antidepressants enhanced the antidepressant response, these observations pertained to elderly depressed women and cannot be generalized to perimenopausal women. There are no studies

of combined estrogen and antidepressant therapies Inhibitors,research,lifescience,medical in women identified as perimenopausal. To assess perimenopausal depression, the pattern and severity of the depressive symptoms should be determined. Perimenopausal status is suggested by the presence of vasomotor symptoms such as hot flashes or irregular Dorsomorphin mw menstrual cycles, although it is entirely possible

that a perimenopausal woman has neither, particularly in the early stages of the Inhibitors,research,lifescience,medical menopausal transition. Careful physical examination Inhibitors,research,lifescience,medical and medical history should be obtained to determine other coexisting conditions, previous experience of any depressive disorder, the onset of the depressive symptoms in conjunction with menstrual cycle changes, and to identify risk factors and contraindications for estrogen therapy. A follicle-stimulating hormone (FSH) level greater than 20 IU/L is a hormonal marker of the Inhibitors,research,lifescience,medical perimenopause, but single measures are considered unreliable because of sporadic follicular activity and competence.

The Ganetespib purchase decline in mean estrogen levels occurs primarily in the year before menopause,138 although there is considerable individual variability. Burger et al recently reported that mean estrogen levels started to decrease about 2 years before Inhibitors,research,lifescience,medical the final menstrual period, but fell substantially only in the year before the final menses with the most rapid decrease around the time of the final menstrual period.139 Recognition that the perimenopause can extend over a number of years and that the hormonal shifts that occur in this transition may be associated with depressive symptoms is important for patient care. However, scientific data to guide treatment of depression in the perimenopause are limited and inconclusive. Estrogen therapy may be helpful for major or minor depression as well as Drug_discovery for depressive symptoms linked to the menopause. OCs containing estrogen are another possible option for perimenopausal women, who still require contraceptive protection, but there is no consistent evidence at this time of their antidepressant effects. The hormone doses of OCs are considerably higher than those of HRT, but only the HRT dose levels of estrogen have shown antidepressant effects in perimenopausal women at this time.

It is clear from Figure 6 that the overall mean correlation between the DMN nodes was higher when using the native space method. Using SPM8-based spatial normalization, we found three interregional Ponatinib correlations in the DMN that were significantly different between young and elder groups: one in the left hemisphere (Hi, MOF); and two in the right hemisphere; (PoC, SM) and (PoC, IP). However,

none of correlations survived Bonferroni correction (P < 0.00056). All three differences were unilateral and reflected a decrease in functional connectivity in elders. Most interestingly, none of the Inhibitors,research,lifescience,medical findings with SPM8 spatial normalization coincides with the findings in native space. However, the significant decrease noted by this method in the left hemisphere between (Hi, MOF) was also marginally significant in native space analysis (P = 0.06). Interhemispheric averaging Figure 7 illustrates the effect Inhibitors,research,lifescience,medical of interhemispheric averaging on the detection of age-related differences in the resting-state BOLD fMRI regional activation. As seen in this figure, interhemispheric averaging has multiple

effects on the correlation statistics. This is better illustrated in the cross-correlogram in Figure 8. Comparing Figures 6 and ​and88 clearly shows that interhemispheric averaging increases the overall correlation mean significantly in both groups. However, there exist a few cases where averaging reduces Inhibitors,research,lifescience,medical the mean correlation (e.g., IP and SM). In general, when the mean correlations in the left or the right hemispheres are close to zero, averaging tends to inflate those correlations. One can roughly observe the following relationship: the higher the interhemispheric correlation, the smaller the effect Inhibitors,research,lifescience,medical of the averaging. Nine significant (P < 0.05) age-related changes Inhibitors,research,lifescience,medical were detected in the

averaged signals: (En, PCu), (En, PoC), (En, MOF), (En, IC), (Hi, SF), (IP, SF), (IP, PCu), (IC, SF), and (IC, PCu). None survive after Bonferroni correction. Among these findings, five pairs showed a decrease in functional connectivity and four showed an increase in functional connectivity in elders. None of the nine detected significant changes was found without averaging left and right signals. However, two of them ([Hi, SF]; P = 0.07, and [IP, PCu]; P = 0.08) were marginally significant in the right hemisphere. The remaining seven significant findings were not found in left or right hemisphere using native space method GSK-3 or the prevailing method by SPM8 in which interhemispheric averaging was not performed.

Bao and Nambu

independently reported two selleck chemicals llc infants with neonatal hypotonia and dilated cardiomyopathy, who died in the first months of life (17, 19). They harboured a splice-site mutation leading to exon skipping in the first case, and a homozygous single-nucleotide deletion in the second (17, 19). Two other cases presented with severe neonatal hypotonia and died within 40 days of life: the first had two single-base pair deletions and the second had a large homozygous deletion encompassing exons 8 to 12 (6). We reported three additional patients (two of them siblings) Inhibitors,research,lifescience,medical with decreased fetal movements and polyhydramnios, severe hypotonia at birth requiring mechanical ventilation, who died at ages ranging from 4 weeks to 4 months. The two siblings showed a nonsense mutation and a large deletion, while the third patient was a compound heterozygote for a nonsense mutation and a missense mutation in a highly conserved Inhibitors,research,lifescience,medical amino acid (7). Decreased

fetal movements, polyhydramnios, severe hypotonia with respiratory insufficiency requiring ventilatory support, also characterized the clinical presentation of a baby-girl, who died at 2 months of age (20). Inhibitors,research,lifescience,medical Recently, Burrow and collegues reported a child with non-lethal congenital hypotonia without www.selleckchem.com/products/AP24534.html hepatic or cardiac involvement, due to GSD-IV. Genetic analysis revealed the presence of two missense utations in the GBE1 gene (14). Adult polyglucosan body disease Adult polyglucosan body disease (APBD, MIM 263570) is a clinical variant of GBE deficiency. It is a late-onset neurological disease clinically characterized

by progressive upper Inhibitors,research,lifescience,medical and lower motor neuron involvement, sensory loss, early urinary incontinence, and dementia in about half of the patients (12, 13). Polyglucosan bodies accumulate in the axons and hillocks of Inhibitors,research,lifescience,medical neurons in both gray and white matter, at difference from the polyglucosan bodies of Lafora disease, which are never seen in neuronal perikarya. To date, genetic analysis of the GBE1 gene identified an homozygous missense mutation – c.986A > C (p.Y329S) – in several Ashkenazi Jewish patients (21). Ubogu and collegues Carfilzomib reported a manifesting heterozygous patient with 48% of GBE activity and a single common Ashkenazi-Jewish Y329S mutation (22). Ziemssen and collegues identified two heterozigous mutations in a non-Jewish patients with reduced GBE activity (c.1544G > A p.R515H.1571G > A p.R524Q) (23). Prenatal diagnosis Prenatal diagnosis can be performed by the measurement of the GBE activity in cultured chorionic villi cells and in cultured amniotic fluid cells (24), or by DNA analysis in genetically confirmed cases (25). Animal models Two naturally occurring animal models with GSD-IV are known, the Norwegian Forest cat and the American Quarter horse. In Norwegian Forest cats, the disease is fatal and affects primarily the striated muscles and the nervous system. A 6.

Neoadjuvant therapies provide numerous theoretical and practical advantages over postoperative treatment: Table 2 Neoadjuvant trials for borderline selleck chem Volasertib resectable pancreatic cancers Malignant cells are more likely to oxygenate preoperatively, allowing radiation to be more effective through the production of radicals causing DNA damage; Preoperative treatment may reduce the likelihood Inhibitors,research,lifescience,medical of tumor spillage, dissemination, or implantation at the time of surgery; Since the irradiated bowel is likely to be resected at the time of pancreaticoduodenectomy, patients treated with preoperative radiotherapy may more experience less long-term nutritional problems compared to patients irradiated postoperatively;

With neoadjuvant therapy, there is no delay between systemic therapy and surgery, as opposed to adjuvant therapy where the delay is caused by postoperative recovery, possibly reducing the control of distant metastases; Neoadjuvant therapies may effectively downstage marginally resectable tumors and render Inhibitors,research,lifescience,medical them resectable. These theoretical advantages are promising, but, to date, there are no randomized

trials that directly compare neoadjuvant and Inhibitors,research,lifescience,medical adjuvant therapies. In a phase 1 clinical trial, Hong et al. demonstrated the feasibility of hypofractionated neoadjuvant proton therapy with concomitant capecitabine for patients with resectable adenocarcinoma of the pancreatic head (11). Fifteen patients received doses ranging from 30 GyE in 10 fractions over 2 weeks to 25 GyE in 5 fractions over 1 week. Chemotherapy consisted of capecitabine at 825 mg/m2 twice daily. No dose-limiting toxicities were observed. Evaluation

of 30-day postoperative mortality and morbidity showed no deaths or anastomotic leaks. Limited elective nodal irradiation was offered. Inhibitors,research,lifescience,medical Of Inhibitors,research,lifescience,medical note, 10 of 11 patients undergoing surgery had positive lymph nodes in the operative specimen. Nichols et al. reported negligible weight loss and gastrointestinal toxicity in a group of 20 patients treated with conventionally fractionated protons and concomitant capecitabine (1,000 mg orally twice-daily) (12). Patients had marginally resectable (N=5), resected (N=5), or unresectable (N=10) disease and received planning target volume (PTV) proton doses Entinostat ranging from 50.40 to 59.40 CGE. No elective nodal irradiation was offered to the patients with measurable gross disease. The median PTV volume was 406 cm3 (range, 244 to 1,811 cm3). For the 17 patients treated with a 2-field plan (posterior oblique and right lateral oblique) which minimized gastric and small bowel exposure, the median weight loss was only 1.1l bs (range, gain of 10.4 lbs to loss of 14.1 lbs) over the course of treatment. No patient experienced grade 2 or greater GI toxicity. Conclusions Protons allow for substantial gastric and small bowel sparing compared with X-rays in the setting of neoadjuvant radiotherapy for pancreatic cancer.
