An intact immune system appears to be critical to tolerating anal cancer treatment. A study from Emory University also found that HIV+ patients with CD4<200 did worse with anal cancer treatment (43). Of 17 HIV+ patients with anal cancer documented at Emory from 1994-2004,

only those with CD4<200 were unable to complete treatment (43). Antiretroviral drugs play a key role in controlling Inhibitors,research,lifescience,medical the HIV virus and helping bolster CD4 counts. Therapy for HIV changed dramatically in the mid 1990s with the implementation of HAART (highly active anti retroviral therapy). HAART therapy includes a combination of protease inhibitors (discovered/designed in 1995) and non nucleosidase reverse transcriptase inhibitors (1996). Widespread use of HAART came around 1999-2000. Papers discussing the use of HAART to aid in anal cancer treatment are thus limited. Hoffman et al (1999) at UCSF suggested that one patient in their cohort of 17 who initially Inhibitors,research,lifescience,medical had a CD4 count less than 200 tolerated the standard of care treatment for anal cancer due to the addition of a protease inhibitor which bolstered the CD4 count to greater than 200 (42). A later study done by Stadler et al (UT Southwestern 2004) demonstrated a trend toward improved efficacy of anal cancer treatment in HIV+ AIDS patient treated with HAART (44). Stadler et al (2004) Inhibitors,research,lifescience,medical compared outcomes in patients treated

for anal cancer preHAART and post HAART (44). The UT Southwestern study differs from the other studies in that the chemotherapy used was 5FU/cisplatin instead of 5FU/MMC. Inhibitors,research,lifescience,medical The RT dose was similar at 54 Gy. In this study all patients had AIDS at time

of diagnosis. Overall, 14 patients were analyzed, including 6 pre HAART and 8 on HAART. Stadler et al (2004) suggested a trend towards better treatment tolerability and outcome in patients treated with HAART. 2 year OS in patients on HAART was 67% vs. 17% in the pre-HAART era. 1yr and 3 yr Sotrastaurin clinical trial mortality pre HAART was only 12% and 40% respectively compared to 67% and 80% for patients on HAART. The success of definitive treatment for HIV+ patients on HAART seems to Inhibitors,research,lifescience,medical fare the same as HIV negative patients in the randomized Calpain control trials. Moreover there was more toxicity in the preHAART patients (60%) compared to the HAART treated patients (50%) (44). It suggests that the HAART and increased CD4 count help patients tolerate treatment. Recent single institutional studies have shown that as long as HIV+ patients can tolerate the standard of care treatment for anal cancer and do not have AIDS (i.e. CD4<200), the efficacy and durability of treatment is similar to immunocompetent patients. A group from Paris (Blazy et al 2005) reported on a cohort of 9 HIV+ men all on HAART treated with chemoradiation (45). They found no correlation between CD4 count and toxicity. Clinical outcome was similar to immunocompetent historical controls (45). Yet another single institutional study from St.

Changes in postoperative measurements over time were analyzed with repeated measurement ANOVA. Paired t-tests were used to compare the ipsilateral and contralateral sides. The results are expressed as mean ± SD and differences are considered significant at P < 0.05. Results TH immunohistochemistry To analyze the impact of 6-OHDA lesions, TH was explored at the level of SNc (Fig. ​(Fig.1A,1A, B). A considerable Selleck 17-AAG decrease in TH staining was observed in the 6-OHDA-lesioned

rats (B) compared to the shams (A). This decrease Inhibitors,research,lifescience,medical in staining was observed in both the SNc and VTA. The impact of degeneration was measured by counting the TH-positive cells within the SNc, revealing a significant decrease in TH-positive Inhibitors,research,lifescience,medical cells in 6-OHDA-lesioned animals (C). Although not counted, a decrease in TH staining within the VTA was also observed and appeared less severe than in the SNc. The TH immunolabeling obtained here is in agreement with previous studies (Paillé et al. 2007; Ouachikh et al. 2013; Zengin-Toktas

et al. 2013). Figure 1 TH immunostaining in sham (A) and 6-OHDA-lesioned animal (B) reveal a drastic decrease in the intensity of staining, mainly in the SNc and less in the VTA. (C) Quantification Inhibitors,research,lifescience,medical of TH cells in SNc: the total number of TH-positive neurons was measured in … Locomotor exploration Locomotor impairment was investigated using the

rotarod technique (Fig. ​(Fig.1D)1D) in both lesioned and sham animals. It revealed significant differences in 6-OHDA-lesioned animals (n = 8), starting from the first week when compared to the shams (n = 8) group (Fig. ​(Fig.1D,1D, week 2: Inhibitors,research,lifescience,medical 55 ± 40 sec vs. preoperative stage: 169 ± 25 sec, ***P < 0.001; week 4: 76 ± 36 sec vs. preoperative stage: 169 ± 25 sec, ***P < 0.001; week 6: 95 ± 29 sec vs. preoperative stage: 169 ± 25 sec, ***P < 0.001). Their activity seemed to improve over time but remained different from their Inhibitors,research,lifescience,medical preoperative score. Dopamine depletion evoked allodynia 6-OHDA-lesioned rats were assessed for DMA from 4 days to 5 weeks after injury (Fig. ​(Fig.2A).2A). A significant pain score difference was obtained in the 6-OHDA-lesioned animals when compared to the shams. The pain increase was observed in the 6-OHDA-lesioned animals throughout the duration of the experiment. A high inverse correlation (r = −0.84; GPX6 P = 0.04) between the allodynic score and the number of TH-positive cells was observed (Fig. ​(Fig.2B).2B). A low TH cell number is correlated with a severe DMA. Figure 2 The graph (A) represents the trigeminal pain score as measured by the Vos index in 6-OHDA-lesioned animals (black) and sham (gray). This result was obtained by the application of gentle air puffing on the right side of the infraorbital region. The left …

14 However, children of schizophrenic mothers who were adopted away and then reared in adverse circumstances have a higher risk than those brought, up in loving homes by stable adoptive parents.148 find more Furthermore, Mirsky et al149 noted that children with known genetic risk for schizophrenia were more likely to develop the disorder if they lived

on a kibbutz, rather than in a family home. Overall, kibbutz children did not have a higher risk, suggesting that high-risk children carry a genetic vulnerability to the social environment. The effect of being born or brought up in a city Several Inhibitors,research,lifescience,medical studies in the 1990s indicated that being born or brought up in a city increases the risk for schizophrenia.150 In one of the most impressive, Mortensen et al151 examined a Danish national sample and showed that the relative risk for schizophrenia, associated with urban birth was 2.4

and that, there was a dose-response relationship (the larger the town of birth, Inhibitors,research,lifescience,medical the greater the risk) suggesting a causal effect. Mortensen and colleagues pointed out that because so many people are born and live in cities, a relatively small increase in risk would cause a large increase in the numbers of people with Inhibitors,research,lifescience,medical the disease. Indeed, they calculated that the population-attributable risk (PAF) for urban birth was 34.6 %, compared with 9 % or 7 % for having a mother or father with schizophrenia, respectively. The estimate of PAF appears robust, as a similar PAF has previously been reported in data from another country,152

Inhibitors,research,lifescience,medical where, in addition, it was shown that the effect of urban birth/upbringing is not confounded by urban residence in adult life.153 Finally, in a further analysis of the above Danish study, Pederscn and Mortensen154 have shown that Inhibitors,research,lifescience,medical the association between urbanization and schizophrenia is based on continuous or repeated exposures during upbringing (not just, urban birth), and that there is indeed a dose-response relationship between urban upbringing and risk for schizophrenia. The risk associated with isolation The Swedish conscript study discussed above also looked at the interaction of premorbid personality and social isolation. Young men who felt, they were more sensitive than their peers, had fewer than two close friends, and did not have a girlfriend had an increased those risk of later developing the disorder.155 Once again this raises the question of whether these characteristics are an expression of a schizoid or schizotypal personality or whether they are in themselves independent risk factors. Until proven otherwise, it is wise to consider that both may be true, ie, individuals with a schizoid or schizotypal personality may be less able to make social relationships, and then the social isolation itself may cause them to become increasingly deviant.

Considering all patent applications in the different fields of nanomedicine, USA hold a share of 53% [4], Europe has 25% [4], and Asia 12% [4]. Biopharmaceutical and medical devices companies are well aware of the potential applications of nanotechnology to the healthcare sector, as demonstrated by the increasingly growing partnerships between these enterprises and nanomedicine startups. According to a research report from the Business Communications Inhibitors,research,lifescience,medical Company (BCC) Research, despite the catastrophic consequences of the 2008-2009 crisis on capital markets, the global nanomedicine sector, which was worth $53 [5] billion in 2009, is projected to

grow at a compound annual growth rate (CAGR) of 13.5%, surpassing $100 billion in 2014 (see Figure 1(a)) [5]. One of the largest segments of this market Inhibitors,research,lifescience,medical is represented by anticancer products. Valued about $20 billion [5] in 2009, it is expected to reach $33 billion [5] in 2014, growing at a CAGR of 11% [5] (see Figure 1(b)). Figure 1 (a) This graph shows the global nanomedicine market size, measured in terms of revenues, such as sales revenues, grants revenues, and milestones. From 2006 to date, a steady growth has occurred,

which is expected to continue through 2014, at a CAGR of Inhibitors,research,lifescience,medical … 3. Financing of Nanomedicine 3.1. Common Issues in the Investments on Innovation The primary output of innovation is obtaining the know-how,

Inhibitors,research,lifescience,medical which the inventor initially possesses. Unfortunately, the confidentiality of this knowledge can be breached and its use by one company cannot preclude the use of the same by another one. Therefore, Caspase inhibitor investors approaching novel projects are aware of the fact that they will not be able to easily appropriate the total returns of the investment undertaken. As a consequence, there is a lack of attractiveness in financing innovative projects. In fact, from the perspective of economic theory, it is complex to find Inhibitors,research,lifescience,medical funding for innovative ideas in a competitive market place [6]. Even in large firms, there is evidence of shortages in resources to spend on the innovative projects that the managers would like to undertake [6]. There are a number of reasons for this phenomenon: low expected returns due to an incapacity to capture the profits Sodium butyrate from an invention, the exaggerated optimism in undertaking an investment on breakthrough projects, and most notably the uncertainty and risk associated with these projects. Technology-based companies can also consider imitating the inventions developed by competitors. However, Edwin et al. [7], using survey evidence, found that imitating is not costless and could result in expenses equal to 50% [7] to 75% [7] of the cost of the original invention, not eliminating the underinvestment problem.

Neuropsychiatric side-effects have been reported in up to 60% of patients undergoing treatment with antiviral agents [Evon et al. 2009]. Most of them (48%) were depressive disorders. More rarely, signs and symptoms check details associated with anxiety, sleep, memory and attention disorders were observed [Lochet et al. 2003; Ward and Curtin, 2006]. Ribavirin, an antiviral agent, has also been reported to cause some psychiatric syndromes, however it is stressed that these effects are often enhanced by the psychiatric side-effects of the other Inhibitors,research,lifescience,medical antiviral agents (such as interferon alpha) which are often used together [Reichard

et al. 1997; Martin-Santos et al. 2008]. We would like to report a case of single-agent ribavirin-induced compulsive buying. The purpose of Inhibitors,research,lifescience,medical this case report is to draw attention to obsessive compulsive spectrum disorders (OCSDs) such as compulsive buying, which, although

not defined as a disorder by the DSM and ICD, may cause clinically significant disability, and also Inhibitors,research,lifescience,medical to its etiology of biological and psychological explanations. A 34-year-old woman presented to our clinic with obsessive fears of becoming contaminated by microbes whenever she touches any item, continuous thoughts of having forgotten to turn the lights off and close windows and doors, uncontrolled repetitive behaviors in the form of a compulsive need to constantly check the doors or lights or continuously wash her hands. She also had sudden and intense desires

to shop and purchase things needlessly. When she postponed Inhibitors,research,lifescience,medical the desire to shop, she experienced severe discomfort and restlessness. She gained relief by buying unnecessary things, hence she faced economical problems due to excessive expenditure, resulting in regret and anxiety feelings. Three weeks prior to her application, she received a prophylaxis treatment consisting of 1000 mg/day oral Inhibitors,research,lifescience,medical ribavirin applied for 7 days since she had pricked her finger with a syringe that had been used on a patient with Crimean-Congo hemorrhagic fever disease. During the medication usage she had no complaint not other than a feeling of dizziness and lack of concentration. The prophylaxis treatment for Crimean-Congo hemorrhagic fever disease was completed and the disease did not appear. The aforementioned psychiatric symptoms and complaints started a week after the completion of this treatment with ribavirin. It was determined via psychiatric examination that she was in an anxious–angry mood, her thoughts included suspicion and contamination obsessions, control and washing compulsions, and intense desire to go shopping; her behavior of purchasing unnecessary things was noted and, after purchasing, she experienced thoughts of guilt. Routine hematological and biochemical parameters were normal.

In addition, preventing recurrent cerebrovascular disease and maintaining sufficient cerebral blood perfusion by adequately managing heart failure and avoiding very low blood pressure may help postpone clinical expression of the dementia syndrome, especially among very old people. The second strategy is to maintain the more active and socially integrated Inhibitors,research,lifescience,medical lifestyles by establishing extensive social networks and frequently participating in social, physical, and intellectually stimulating activities, which may reduce the risk or delay the onset of AD.38,132 Taken together, the most effective strategy may be to encourage, people implementing

Inhibitors,research,lifescience,medical multiple preventive measures throughout the life course, including

high educational attainment in childhood and early adulthood, active control of vascular factors and disorders over adulthood, and maintenance of mentally, physically, and socially active lifestyles during middle age and later in life. Intervention trials toward primary prevention The main clinical and intervention trials toward primary prevention by targeting the possible risk and protective Inhibitors,research,lifescience,medical factors for AD and dementia are summarized in Table II. 160,161,176-182 Antihypertensive treatments in reducing the risk of dementia and AD have been tested in a Inhibitors,research,lifescience,medical few clinical trials. The pooling analysis of the 2007 Cochrane review, based essentially on three clinical trials (SHEP,183 Syst-Eur,184 and SCOPE185),

found no convincing evidence that blood pressure-lowering therapy among elderly individuals with hypertension could prevent dementia. However, in this review the SCOPE trial, which did not show any effect of blood pressure-lowering treatment by candesartan on the risk of dementia, was Inhibitors,research,lifescience,medical actually not a placebo-controlled trial due to ethical considerations. By contrast, the placebo-controlled PROGRESS trial among individuals with cerebrovascular disease, (transient ischemic attacks and stroke), which did find a beneficial effect of antihypertensive therapy on cognitive function related to recurrent stroke, was not included.186 The cognition substudy of the double-blind placebo-controlled Hypertension in the Very ALOX15 Elderly Trial (HYVET-COG) among people 80+ years found a nonsignificant reduction in the risk of dementia related to antihypertensive treatment. Encouragingly, when data from this clinical trial were pooled together with those from three other selleck doubleblind placebo-controlled trials (SHEP, Syst-Eur, and PROGRESS), antihypertensive treatment could reduce the risk of dementia by 13 % (hazard ratio, 0.87; 95 % CI, 0.76-1.00; P=0.045).

Depressed subjects report nocturnal restlessness, feeling tired, waking up too early, and being unable to return to sleep. Sleep-onset difficulties are more prominently seen with younger subjects, whereas problems with sleep continuity are more characteristic of older subjects. The characteristic insomnia associated with depression Is a harbinger of the mood Selleck STI571 change, often beginning before the clinical depression has been clearly established.13 In addition to Insomnia and hypersomnia, other sleep abnormalities have also been reported In association with depression. In the Wisconsin Sleep Cohort study of 812 participants from 1998 to 2002, depression

Inhibitors,research,lifescience,medical was associated with a 2.0-fold Increase In hypnagogic hallucinations

(≥1/month), 2.1 -fold Increase in automatic behavior (≥1/month), 5.1-fold Increase in sleep paralysis (≥/month), and 1.3-fold Increase in cataplexy (≥/month).15 Polysomnography: abnormalities can be seen In 40% to 60% of Inhibitors,research,lifescience,medical outpatients and 90% of Inpatients with a depressive episode.7 Sleep continuity is Impaired with prolongation of sleep latency In younger subjects, increase In intermittent wakefulness, and early morning awakenings. Slow-wave sleep (SWS) Inhibitors,research,lifescience,medical Is reduced (decreased percentage of stage 3 to 4 NREM sleep), and delta activity Is decreased, as demonstrated by period-amplitude or power spectral analysis. Quantitative electroencephalographic (EEG) studies may show a change

in the delta sleep ratio between the first and second NREM period, reduced amplitude of Inhibitors,research,lifescience,medical slow-wave activity In the first NREM period, and decreased Interhemlspheric beta and theta coherence and Intrahemispherlc coherence Inhibitors,research,lifescience,medical between beta and delta rhythms.16-20 Rapid eye movement (REM) sleep Is enhanced, with Increased percentage of REM sleep and phasic movements during REM sleep. Temporal characteristics of sleep are altered with short ened REM sleep latency, reduced delta activity In the first NREM period relative to the second (reduced “delta sleep ratio”), increased phasic eye movement activity, and increased REM sleep duration during the first REM period.7,13,21,22 Analysis of the cyclic alternating pattern reveals an increase in phases A2 and A3 and a also decrease In phase Al during NREM sleep highlighting an Instability of NREM sleep In depressed patients.23 Dysthymic disorder Like MDD, sleep In other affective disorders, such as dysthymic disorder, is also disturbed. Approximately 5.4% of the US population aged 18 and older suffers dysthymia during their lifetime. In the USA, 10.9 million American adults are affected.1 Women are affected two to three times more frequently than men. Dysthymia is characterized by at least 2 years of frequent depressed mood accompanied by various symptoms.

5, 95% CI 1.7-34.1, P=0.002). When it occurred, oligomenorrhea began within the first 12 months of valproate use. This study demonstrated an association between valproate and new-onset oligomenorrhea with hyperandrogenism in women with bipolar disorder. A subsequent follow-up study Ku-0059436 in vivo completed follow-up assessments (after 17+I-7-months) in 14 Inhibitors,research,lifescience,medical women (5/9 with treatment-emergent PCOS, 9/1 9 valproate use “6 months).41 Of 7 women who developed

valproate-asso ciatcd PCOS, reproductive features of PCOS remitted in 3/4 women discontinuing valproate and persisted in all 3 continuing valproate. Compared with women continuing valproate, menstrual-cycle irregularities improved among valproate discontinucrs whose PCOS features remitted (P=0.01). There was a trend toward lower serum testosterone (P=0.06). Body weight,

was unchanged. Valproate may also be associated with PCOS features because increase in body weight Inhibitors,research,lifescience,medical or insulin resistance secondary to valproate therapy36,42-43 may lead to the development of PCOS through insulin effects in the ovary.44 However, menstrual-cycle irregularities or PCOS are uncommon in women with obesity or type 2 diabetes.45-47 Prospective research is needed to examine the relationship between weight, insulin resistance, and predisposition or development of PCOS features. The Inhibitors,research,lifescience,medical collective literature demonstrates that rates of menstrual disturbances are high in women with bipolar disorder, regardless of their treatment history. It appears that treatment with valproate further predicts the development of menstrual abnormalities and an increase in testosterone levels over time. However, little is known about the additive impact of previous exposure, duration of exposure, and age of women who are most vulnerable

Inhibitors,research,lifescience,medical to development of this constellation of symptoms.48 More research is needed to understand the relationship between etiology of reproductive and hormonal irregularities, onset of bipolar disorder, and treatment history. Endocrine effects of medication treatments Women Inhibitors,research,lifescience,medical are at greater risk than men for the development of lithium-associated hypothyroidism. Clinical hypothyroidism during lithium treatment is present, in 14% of women, versus 5.5% of men.49 Lithium-treated women may also be at higher risk for lithium-induced thyroiditis.13 Effects of pharmacotherapy Sclareol on oral contraceptives The efficacy of oral contraception (OC) can be impaired by concomitant use of medications that induce liver enzymes (eg, carbamazepine, oxcarbazepine), which may be secondary to enhanced hepatic metabolism of the OC hormones. Therefore, if women are prescribed these medications for treatment of symptoms of bipolar disorder, clinicians should advise them to use barrier methods of birth control, monitor for spotting, and/or work with the gynecologist to increase oral contraceptive pill (OCP) dose.

The distribution of sufficient thermal dose is then calculated and assumed to correspond to thermally ablated tissue. The temporal resolution of MR thermometry is 1-4 seconds per image, and the spatial resolution is determined by the size of the image voxel which is typically about 2mm x 2mm x 6mm

(40). Therefore, MR-guided HIFU is only suitable for treatments in which the heating occurs slowly, on the order of tens of seconds for a single lesion. Motion artifact due to breathing and heartbeat is also a concern in clinical setting. The only US FDA-approved HIFU device available for clinical therapy utilizes MR thermometry Inhibitors,research,lifescience,medical during treatment of uterine fibroids (39),(41). Ultrasound imaging Inhibitors,research,lifescience,medical used in current clinical S3I-201 purchase devices does not have the capability of performing thermometry, but it provides real-time imaging using the same energy modality as HIFU. This is a significant benefit, because adequate ultrasound imaging of the target suggests that there is no obstruction (e.g., bowel gas or bone) to ultrasound energy reaching the target, and the risk of causing thermal injury to unintended tissue is minimized. One method that Inhibitors,research,lifescience,medical is sometimes used for confirmation of general targeting accuracy is the appearance of a hyperechoic region on the ultrasound

image during treatment. This region has been shown to correspond to the formation of a large boiling bubble at the focus when tissue temperature reaches 100°C, and underestimates the actual size of the thermal lesion since thermal lesions develop at temperatures

below Inhibitors,research,lifescience,medical 100°C (42). Imaging methods to assess HIFU treatment are similar to those used to assess the response to other methods of ablation such as radiofrequency ablation and include contrast enhanced CT and MRI (43). In addition, the use Inhibitors,research,lifescience,medical of microbubble contrast-enhanced sonography is also being examined as a method to evaluate the treatment effect of HIFU (44). These methods all examine the change in vascularity of the treated volume. HIFU of pancreatic tumors Devices Currently, HIFU treatment of pancreatic cancer is widely available in China, with limited availability in South Korea and Europe. There are two US-guided HIFU devices that are commercially available outside of China for treatment of pancreatic tumors, both manufactured in China: The FEP-BY™ HIFU tumor therapy Parvulin device (Yuande Biomedical Engineering Limited Corporation, Beijing, China, Figure 4) and HAIFU (Chongqing Haifu Technology Co.,) (45). Both devices operate at similar ultrasound frequencies – 0.8 and 1 MHz respectively; both are capable of putting out total acoustic power of about 300 W (corresponding intensity up to 20 000W/cm2). B-mode ultrasound is also used in both machines for targeting and image guidance. In addition, a patient with pancreatic tumor was recently treated in Italy using the MR-guided ExAblate™ system (InSightec, Israel) for palliation of pain.

Our patient had none of the classic predisposing factors for hepatic lymphocytic proliferation, such as chronic viral hepatitis, HIV, EBV or autoimmune hepatic disease. However, other mechanisms for the development of NHL in celiac disease may be implicated. It is also possible that this may be an entirely fortuitous association.

In the United Androgen Receptor pathway Antagonists States, colorectal cancer (CRC) is the third most common incident cancer and the third highest cause of cancer death for both men and women (1). When CRC is diagnosed at an early stage, the 5-year relative survival is 90.4%, but for patients with metastatic disease, 5-year survival Inhibitors,research,lifescience,medical is only 11.6% (2). Factors associated with stage at presentation and survival include race (3), gender (3), socioeconomic status (SES) (4,5), and molecular abnormalities, such as abnormal expression of p53 (6). Although SES has emerged as an important factor relating to CRC, the mechanism through which it affects survival Inhibitors,research,lifescience,medical has not been elucidated. There is a need to identify genetic factors that contribute to SES differences and to progression of CRCs. Genetic alterations, including those in the p53 gene, occur during the development of CRCs (7). Patients whose CRCs exhibit nuclear accumulation of p53 (p53nac) have decreased survival

Inhibitors,research,lifescience,medical after resection, and p53nac may be a useful Inhibitors,research,lifescience,medical prognostic factor (8,9). Although patient race/ethnicity and SES are related, they do not measure the same construct

(10). Therefore, it is important to determine if SES and race are associated with p53nac. Environmental factors associated with SES may be related to the genetic alterations in carcinogenesis. For women with breast cancer, p53 mutations were associated with SES Inhibitors,research,lifescience,medical and may have an association with the poorer prognosis of women of low SES (11). Thus, there is a need to identify the genetic factors that contribute to SES differences and progression of CRCs. This study aimed to evaluate the association between measures of SES, including health insurance and employment status, and p53nac among a cohort of patients with CRC. Patients and methods Patients An existing database for a cohort of patients (N=1,135) who received curative or palliative resection for sporadic CRC at the University of Alabama at Birmingham from 1981 to 2002 was utilized for this study. This investigation, which during was approved by the Institutional Review Board at the University of Alabama at Birmingham, did not require informed consent. The data were obtained from medical records, physician charts, and surgical pathology and radiology reports. For a subset of patients, archival tissues were obtained and evaluated for p53nac status (N=590). Only patients with data on both SES and p53nac status were included for this analysis (N=249).
