A chest X-ray showed moderate cardiomegaly with increased pulmonary vascularity (Fig. 1A). Both transthoracic and transesophageal echocardiography showed multiple new vegetations at the aortic valve (Fig. 2A) with severe aortic regurgitation. The right aortic sinus of Valsalva and right coronary artery was aneurysmally dilated and coronary artery-ventricular fistula drainage into right ventricle was observed. Her neurologic manifestation was considered as an embolic complication

of the vegetations and emergency operation was performed. Operation finding showed moderate Inhibitors,research,lifescience,medical amount of pericardial effusion, multiple vegetations involving all aortic cusps and large sized right coronary artery communicated with right ventricular cavity, which needed aortic valve replacement, coronary artery-right ventricle fistula devision and obliteration. Identified organism by blood Inhibitors,research,lifescience,medical culture was Streptococcus mitis. Her condition was rapidly stabilized with appropriate antibiotics after operation. She was discharged

uneventfully 3 weeks later and her chest X-ray showed normal heart size without any pulmonary congestion (Fig. 1B). Fig. 1 A series of chest X-ray. Preoperative chest X-ray showed moderate cardiomegaly with increased pulmonary vascularity (A). Cardiomegaly and pulmonary congestion after operation was resolved (B). In 8 weeks Inhibitors,research,lifescience,medical after surgery, chest X-ray showed aggravated Inhibitors,research,lifescience,medical cardiomegaly … Fig. 2 Representative

echocardiograms. Preoperative transesophageal echocardiography showed multiple vegetations attached to aortic valve (A). After uneventful aortic valve replacement, moderate pericardial effusion (PE) with typical constrictive physiology … In 8 weeks after surgery, she had sudden onset of pleuritic chest pain with orthopnea and generalized edema. Chest X-ray revealed marked cardiomegaly (Fig. 1C). Echocardiography showed Inhibitors,research,lifescience,medical moderate amount of pericardial effusion with thickened pericardium, fibrin strands, multiple septations in pericardial space (Fig. 2B), inspiratory decrease of transmitral inflow (Fig. Adenosine 2C), and CI-1033 markedly dilated inferior vena cava with spontaneous echo-contrast and plethora. Postoperative effusive-constrictive pericarditis was final diagnosis and ibuprofen (400 mg 3 times daily for 3 weeks) and prednisolone (1 mg/kg daily for 3 weeks) was prescribed. Her symptoms were improved very dramatically and chest X-ray showed normalized heart size within 1 week (Fig. 1D) and echocardiography revealed dramatic disappearance of pericardial effusion and constrictive physiology (Fig. 2D). The steroid was tapered over 7 weeks with improvement of symptoms and signs. Steroid was discontinued. Chest X-ray showed no cardiomegaly (Fig. 1E). In 3 months after steroid discontinuation, she complained pleuritic chest pain and dyspnea again. Chest X-ray (Fig. 1F) and echocardiography (Fig.

The questionnaire was first translated into Farsi, i.e. the language of the study population, and then converted into English. Score 1 was allocated to each question if the answer was yes, scores between 0 and 3 denoted sleeping well (first group), scores between

3 and 6 indicated sleeping quite well (second group), scores between 6 and 9 signified sleeping quite badly (third group), and scores between 9 and 12 stood Inhibitors,research,lifescience,medical for sleeping badly (fourth group). Regarding the reliability and validity of the questionnaire, after completing the first 35 questionnaires, based on SPSS, Cronbach’s alpha coefficient was reported to be 0.7526 (>0.7). Accordingly, the questionnaire had reasonable validity and reliability in

this study. Table 1 Authors’ revised sleep history questionnaire Inhibitors,research,lifescience,medical (adopted from tenth edition of Kaplan & Sadock synopsis of psychiatry) This study was approved by the Ethics Committee of Birjand University of Medical Sciences. All the patients and controls were fully informed about the study protocol, and a signed informed consent was obtained from each of them. The data were then analyzed with SPSS software (version 13). Age and sleep requirement between the two groups were compared using Inhibitors,research,lifescience,medical the t test. Also, the Kruskal–Wallis test was used to compare the mean level of 24-hour urine 6-sulfatoxymelatonin (in hours) in each group, and the Mann-Whitney test was employed to compare the mean level of 24-hour urine 6-sulfatoxymelatonin between the two groups. Additionally, the chi-squared test was utilized to compare sleep distribution

from the point of quality and quantity between the two groups. A p value Inhibitors,research,lifescience,medical less than 0.05 was considered statistically significant. Results The study population comprised 140 Selleck BAY 87-2243 individuals, divided into two equally numbered groups: a case group at a mean age of 54.8±12.2 and a control group at a mean age of 54.4±12.1 years. Age and sex between the two groups were comparable (table 2). Table 2 Demographic data and melation in level Inhibitors,research,lifescience,medical of the patients compared with the controls There was no significant difference between the case and control groups regarding sun and light exposure duration (P=0.9). The mean level of 24-hour urine 6-sulfatoxymelatonin in the case group was 15.9±8.1, while it was 47.0±23.6 in the control group. no This was in accordance with the duration (quantity) and sleep quality in the two groups inasmuch as the control group slept more and better than did the case group generally (P=0.005) (table 3). Table 3 Sleep quantity and sleep quality of the patients compared with the controls Discussion The results of the present study demonstrated that the case group had a lower level of 24-hour urinary 6-sulfatoxymelatonin, which may be interpreted that lower levels of melatonin are correlated with a rise in the risk of SCC and BCC.

g., AD). There is still a limited amount of evidence available with regards to the rates of success for CT programs for individuals experiencing cognitive decline as a result of age-related diseases. To my knowledge, no CT programs have examined the specified role of VS/VM training in affecting generalized cognitive

and functional ability, despite it being currently recognized as a significant factor early in the course Inhibitors,research,lifescience,medical of cognitive impairments related to cases of AD (Johnson et al. 2009; McKhann et al. 2011). The goal of this pilot program was to examine the effects of CT that focus on using mainly VS/VM tasks as a tool to effect positive changes in cognition and functional ability in individuals experiencing cognitive impairments. A program was developed and designed to address current issues (e.g., duration, regular application, and difficulty) and to use mainly VS/VM elements, and thus Inhibitors,research,lifescience,medical hypothesized to provide sufficient stimulation to halt and/or positively alter overall cognitive performance. Theoretically, we are postulating that if the brain regions (e.g., posterior partial cortex) supporting VS/VM are affected Inhibitors,research,lifescience,medical early in the course of an illness like AD (causing initial cognitive impairments), then providing a program of stimulation, not remediation, could serve to protect this area from further

decline and subsequently be available to support other brain regions as cognitive issues arise. Although internal changes in affected brain structure are suggested, the role of this research is in understanding cognitive/behavioral changes Inhibitors,research,lifescience,medical that can be altered via the CT program, and not in measuring structural/anatomical brain changes that might be

observable with the application of such a program. Inhibitors,research,lifescience,medical However, understanding the full extent of what VS/VM CT can achieve with regards to overall “brain change” will be a topic for further examination. Material and Methods AG-14699 participants Ten participants were recruited from clinical practices, the local hospital’s geriatric outpatient clinic, and through community advertisements. Inclusion/exclusion criteria required participants to be between 50 and 85 years of age, have an Mini-Mental State Exam (MMSE) score between Levetiracetam 20 and 26, experience an identified cognitive impairment, and to either be on a stable dose of cholinesterase inhibitors (C.I.) for a minimum of 3 months and/or have no medicative intervention to date (all but one participant was on a stable dose of C.I. at least for 3 months prior to study enrollment). Access to medical history was provided by all participants and any participant with known probable secondary causes of dementia or significant comorbidities, neurological, or psychiatric diseases were excluded. Demographics for participants are presented in Table 1. Table 1 Demographics.

Reconfigured times: constraints We previously discussed how emergency care was deemed unsatisfactory because of the long waiting times, particularly for patients with minor injuries

or illnesses who were constantly pushed to the back of the queue. The 4 hour wait target was intended to minimise this failure of the system by attempting to control time in emergency care work, often by dividing the overall patient volume into Inhibitors,research,lifescience,medical smaller, more homogenised units. However, no matter how well-configured these processes were, the messiness of real-world practice would inevitably interfere. Processes interfered with one another, obstructed the ordered flows of patients and stretched the department’s capability for meeting Inhibitors,research,lifescience,medical the target. For example, a patient attending an ED with a presenting complaint could not always be maintained in the same stream for her entire trajectory. Clinicians had to deal with these irregularities on the spot. Therefore, patients were only allocated to streams temporarily. They Inhibitors,research,lifescience,medical acted as a first attempt to briefly (and quite vaguely)

determine the expected resources and people that would be needed for a particular condition. This was a new managerial task and an opportunity for workarounds to best serve patients’ needs. “I am going to be putting them in the ‘majors’ area and they need to be seen quite quickly, but because they are in ‘minors’ still, or do they automatically Inhibitors,research,lifescience,medical become a ‘majors’ because they’ve got a nasty injury? Or are they still a ‘minors’ because it’s an injury? The other one would be with injuries again, you’ve

got your 26s Proteasome structure category 6 which is your doctors’ minors and you’ve got your category 7 which is your ENP and then your category 4 which is your ENP priority, but you’ve not got a category for doctors’ priority ‘minors’, so they would just go as a 6, if they need to see a doctor and they were an injury, but then how do you put down”; (Clinician 7). However, the Inhibitors,research,lifescience,medical busier it got in the ED, the greater the need to speed up clinical performance. The target, more than actual illness and its urgency, gradually Linifanib (ABT-869) became a critical measure of accountability and, crucially, the target had the authority to instigate specific actions. “Obviously, if there is a patient that needs to stay in the Department because they are unstable or because of their clinical condition, there’s a lot of pressure put upon the nurses in charge or the coordinators…that they move them” (Clinician 1). There were many legitimate reasons why critical (to the target) delays may unfold in the ED, such as waiting for test results or for a specialist to come and see a patient. The ED inevitably required the timely cooperation of many different clinical units and professionals from elsewhere in the hospital.

The addition of adjuvant radiotherapy has been reported in select cases, when there is incomplete resection of the tumor especially for the malignant variety. Although ifosafamide and doxorubicin have been reported beneficial for recurrent or inoperable SFT, repeat surgical resection should be sought first. Also, neoadjuvant radiation therapy or brachytherapy have been described for large malignant tumors although this is not supported by evidence (123). Generally SFTs carry a good prognosis, with low recurrence and metastasis rates. In fact, systemic spread is described in only 8% of cases reported in the literature (115). Selleck MDV3100 Higher rates of local recurrence are generally reported for extra-pleural Inhibitors,research,lifescience,medical SFTs probably

due to smaller excision margins in relation to the anatomic localization of the tumor (118). Positive margins, tumors size greater than 10 cm or malignant histology, are risk factors for local failure Inhibitors,research,lifescience,medical for extra-pleural SFTs (118). One study found that the rate of local recurrence is 8 fold greater in cases with malignant features (115). The metastatic potential of extra-pleural SFTs appears to be low (124). There Inhibitors,research,lifescience,medical are only 5 reported cases of anorectal SFT (124-128). Two cases occurred within the ischioanal fossa, one was of rectal origin and reoccurred in the perineum, one originated in the mesorectum and one involved both the rectum and uterus. Four out of 5 patients were male and mean age at diagnosis was 45. Average

tumor size was 10 cm (range, 7-13 cm). All cases were treated surgically. Two patients had excision of the tumor through an abdominal approach, with sparing of the rectum (126,127); two patients underwent an APR (124,128), one underwent a perineal extra-peritoneal procedure. Inhibitors,research,lifescience,medical None of the patients received adjuvant Inhibitors,research,lifescience,medical chemotherapy or radiation. Follow up data was available in only 3 out of the 5 cases, and ranged from 6 months to 13 years.

Both patients who underwent APR had local recurrence, at 6 months (124) and 13 years (128) and received radiotherapy with embolization of the internal pudendal arteries to reduce the tumors size prior to re-excision. PD184352 (CI-1040) No systemic metastasis has been reported from any of the anorectal SFT cases. Excision with clear margins should always be the goal for anorectal SFT, however, optimal margin size remains unknown. Radiotherapy should be reserved for cases with malignant features, positive margins, unresectablility or preoperatively in the case of recurrence (115). However, radiation does not replace proper negative margin surgical technique. Similar to SFT of the pleura, systemic therapy with ifosfamide or doxorubicin may be considered in recurrent cases or those that show malignant features (123). Schwannoma While historically viewed as a subtype of gastrointestinal autonomic nerve tumors (GANTs), schwannomas are now regarded as a separate entity due to their unique immunohistochemical characteristics (129-131).

Perceptions about training and education Among the greatest

challenges that nurses perceived to be associated with ACP were their own and colleagues’ knowledge and skills about communication practice, recording and follow up: …we’ve still got – when you look at teams – a lot of nurses that aren’t confident to have those conversations. They say: ‘ well you like palliative care, you’re good at it’, and they back off …That’s my worry – the confidence of the staff, teaching them to do it and then following it Cyclosporin A nmr through (Macmillan Nurse). I’ve been in the post three years, so for me it’s the uncertainty or where you do document all this information Inhibitors,research,lifescience,medical and actually how you can get it through to other people so the patients’ wishes are respected – the documentation is a big thing for me (Community Matron). Nurses recommended that training and education should occur in Inhibitors,research,lifescience,medical several ways. Alongside formal training and education, whether by face-to-face teaching or distance learning, some saw the use of

mentorship and apprenticeship styles of training as crucial, so that less experienced staff could learn from their more experienced colleagues: I think there is so much to learn about communication skills and dealing with patients which you can emulate from a role model. And I feel very passionately that Inhibitors,research,lifescience,medical junior nurses need to work with senior nurses much more at the bedside, not in the classroom because I think there’s a theory and practice divide (Macmillan Nurse). Those who were involved in care homes perceived a need to provide ongoing support and mentorship of

this type to care home staff, particularly to care home managers, so that ACP could Inhibitors,research,lifescience,medical gradually become embedded in practice there and so that care staff could gain confidence in dealing with GPs and visiting clinical staff. Drawing on their experiences of receiving training which had largely focused on the implementation of the Mental Capacity Act, nurses recommended that the following should be included in any Inhibitors,research,lifescience,medical education programme to ensure familiarity with the broader aspects of ACP: • Design of ‘real’ scenarios for training, which reflected the reality of daily practice and reflected the variety of patients and people encountered during community nursing • Design of a flow chart to inform nurses and others about the various stages of ACP • Practical advice about communication and documentation. Those nurses who were already Adenylyl cyclase involved in ACP practice, perceived the importance of ongoing support/clinical supervision as a means of building confidence and safe practice. This was perceived to be just as crucial as knowledge and skills training. Discussion This paper reports one aspect of a larger study, which recruited a relatively small number of community nurses working with patients with palliative care needs in two cancer networks in England.

Prognostic is very modest with an overall 5 years survival rate at less than 4%, the lowest of all solid tumours. Medical or surgical palliative treatment can significantly increase the comfort of life, but only modestly increases survival. Only in a subset of patients, with T1 tumour (TNM classification), resectional surgery can be curative, with a 5 year survival rate reported was 20% (3). Adiponectin is an adipokin product of mature adipocyte, reduced in the case of insulin resistance and positively correlated with insulin sensitivity. Adiponectin regulates intracellular pathways of protein Inhibitors,research,lifescience,medical kinase activated by AMP (AMP-kinase), of c-JUN and c-JUN N-terminal kinase (JNK) and of the signal that transcribes

and activates transcription 3 (STAT3). Therefore, adiponectin is an anti-inflammatory, anti-angiogenic and Inhibitors,research,lifescience,medical a block for cell growth. Circulating concentrations of adiponectin are inversely correlated to the risk of several cancers: breast cancer (4), endometrium (5), prostate (6), clear cell cancer kidney (7), stomach cancer (8) and leukemia (9). Prospective studies have shown that there is, at distance, a major risk of breast cancer (10), endometrial (11) and colo-rectal cancer

(12) in postmenopausal women if adiponectin serum level is low. Adiponectin present a direct antitumor (13) and proapoptotic effect. Conversely, in pancreatic cancer, results about Inhibitors,research,lifescience,medical ADP are conflicted (14),(15). The principal aim of our study was to compare Inhibitors,research,lifescience,medical ADP concentrations in two groups of cancer (GSK1210151A colorectal cancer and pancreas cancer) matched on age, sex and tumour staging (metastatic

or non metastatic). Patients and methods This prospective study included all consecutive patients with a new diagnosis of pancreatic adenocarcinoma followed in a referent university hospital between January 2006 and September 2007. The control group included patients with new diagnosis of colorectal carcinoma diagnosed in the same period and matched for sex, age and tumour staging (metastatic or non metastatic tumour), according to the sixth edition of American Joint Committee on Cancer: tumour, node, metastasis (TNM) classification Inhibitors,research,lifescience,medical system. In all cases diagnosis was histological or cytological. All patients were informed and signed a consent paper. Patients on chemotherapy or on antidiabetic treatment were excluded from the study. All patients were characterized by age, sex, body mass index (BMI) before and at the moment of diagnosis, the Suplatast tosilate presence of diabetes according to the criteria of the American Diabetes Association. When diabetes was pre-existing, we evaluated the interval between diagnosis of diabetes and diagnosis of pancreatic cancer. We noted a family history of diabetes, and the presence or absence of an associated dysmetabolic syndrome: hypertension, dyslipidemia, obesity. Tumour data were: stage, size and tumour markers (CEA and CA 19-9); patients were divided into two groups: resectable cancer or locally advanced/metastatic.

Nevertheless, because of unfavourable tumor location, inadequate hepatic

reserve or disease extent, only 20-40% of patients with CLM will be candidates for HR in the contemporary era (13,17). For patients who are not suitable for HR of CLM, several liver-directed therapies and adjuncts have been proposed to expand the indications for potentially curative therapy. Intraparenchymal ablative techniques, including Inhibitors,research,lifescience,medical radiofrequency ablation (RFA), microwave ablation (MWA) and cryoablation, have been widely studied (18). Unfortunately, high local recurrence rates of around 40% and the lack of long-term outcomes data have precluded the widespread adoption of these techniques (3,18,19). Many investigators have argued that ablation should only be used sparingly and restricted to patients with small lesions (3,20-23). Conversely, other investigators Inhibitors,research,lifescience,medical have proposed that ablation is effective, both as adjunct to HR or as an

isolated treatment option for patients with limited hepatic involvement or solitary metastases (17,24-29). Although significant efforts made by the surgical oncology community to define the role of ablation, further studies are necessary. Inhibitors,research,lifescience,medical In particular, although studies have shown that in patients with resectable disease, the outcomes of resection compared to combined resection and ablation are similar, there is significantly less comparative data for multiple lesions. Some studies included patients with extra-hepatic disease leading to confounding of the results to evaluate each treatment modalities. The aim of the current study was to evaluate the role of resection, combined resection and ablation Inhibitors,research,lifescience,medical and isolated ablation in the management of a large learn more number of patients with isolated CLM. More specifically, we sought to determine the influence of treatment type Inhibitors,research,lifescience,medical on outcomes for patients with 1-4 and ≥5 lesions, respectively. Patients and methods We reviewed the records of 701

consecutive patients with colorectal hepatic metastases without extra-hepatic disease who underwent hepatic intervention from a prospective Carnitine palmitoyltransferase II database. All procedures were performed at the Hepatobiliary Service of the University of New South Wales, Department of Surgery, St George Hospital between April 1990 and December 2010. All patients had previously diagnosed colorectal cancer and were treated with curative intent. Patients were evaluated with a baseline medical history, clinical examination, serum laboratory tests including the tumor marker carcinoembryonic antigen (CEA), computed tomography (CT) angiogram of the liver, whole body CT (chest, abdomen, and pelvis), and chest radiography. Patients who underwent open and close procedures without hepatic intervention for their tumor were excluded from this study.

In humans, metyrapone blocks the final step of cortisol synthesis, that is, 11-α-hydroxylation. In the single oral dose test using metyrapone, the synthesis of cortisol is blocked for about 8 hours, and then returns to normal. Therefore, one can measure the levels

of ACTH (which also reflect the equimolar release and levels of beta-endorphin) following metyrapone administration which are elevated because with Cortisol synthesis blocked, and the normal negative feedback is transiently cut off. In healthy human beings, with normal endogenous opioid systems, the mu-opioid receptor Inhibitors,research,lifescience,medical system responds to bring a check, or brake, to the increased release and levels of ACTH (and beta-endorphin). However, we had shown in several earlier studies that in medication-free, drug-free former heroin addicts, there is no such mu-opio!d receptor-mediated

brake, and thus hyper-responsivity to metyrapone testing is observed (reviewed in refs 5,7). Further, Inhibitors,research,lifescience,medical we had reported that in abstinent cocaine addicts a similar hyper-responsivity to metyrapone testing exists.50 This hyper-responsivity, therefore, suggests a relative endorphin deficiency, which our laboratory -based studies also support.30-33,50 As discussed Inhibitors,research,lifescience,medical above, we have found that chronic binge cocaine administration causes an increase in gene expression in the mu-opioid receptor, as well as an increase in density in mu-opioid receptors, in specific brain regions with abundant dopaminergic terminals, and, further, in recent studies, we have found that this increase in mu-opioid receptor density persists for a protracted period of time after last cocaine Inhibitors,research,lifescience,medical exposure.30,32-35 However, we have also shown that there is no increase of the endogenous opioids that bind at the mu receptor. Thus a relative endorphin deficiency develops (or possibly was present a priori on a genetic or environmentally-induced basis). Subsequently,

Frost and colleagues, using positron emission tomography Inhibitors,research,lifescience,medical (PET) showed similarly the mu-opioid receptor density being increased in recently-abstinent cocaine addicts, and further more recently have shown that this increase persists for protracted periods of time into successful check cocaine abstinence.55,56 Thus, a relative endorphin deficiency has been documented both in ROCK inhibitor humans as well as in rodent models, in humans directly shown by testing of the stress-responsive system. In several studies, we have found that metyrapone responsivity is abnormal in opiate addicts, but becomes normalized in methadone maintenance patients (reviewed in refs 5,7). We also have shown that abnormal hyper-responsivity occurs in cocaine addicts.5,7 In a more recent study, we again documented the normalization during methadone maintenance treatment.

69 Although in the Adult Changes in Thought (ACT) and Nun Studies, nondemented seniors with severe AD pathology (mean age of 89.15±6.9 to 90.80±5.2

years) amounted to 8% and 12%, respectively, most of them showed neuritic Braak stage V, and frontal NFT counts were slightly lower than in a comparable dementia group.49 Moreover, review of clinical data from those studies revealed that most of the seniors classified as nondemented were indeed significantly memory-impaired.49 Inhibitors,research,lifescience,medical A recent study of nondemented elderly demonstrated 62% with low and 28% with high NFT levels70; 87 nondemented elderly (mean age 87 ±5.9 years; mean MMSE 28.3) showed mean Braak stage 3.0±0.9, a total NFT score of 4.5±2.5, and mean neuritic density of 1.3±1.1, whereas AD cases showed much higher cortical neuritic and striatal amyloid plaque scores.71 The 90+ study revealed significantly less severe Aβ, α-synuclein, and TPD-43 pathologies,

and hippocampal sclerosis in nondemented subjects, while Aβ distribution showed no essential differences; Inhibitors,research,lifescience,medical nondemented individuals had limited hippocampal tau and neocortical Aβ pathology.72 A recent clinicopathologic study of 296 persons without cognitive impairment of the Religious Inhibitors,research,lifescience,medical Order Study (ROS) and the Memory and Aging Project (MAP) showed a common presence of AD pathology and macroscopic infarctions. Amyloid load was related to global cognition (P<0.05), with only a trend for NFTs (P =0.08), while NFTs and macroscopic infarctions were related to episodic memory (P =0.03 Inhibitors,research,lifescience,medical and 0.02, respectively); AD pathology and Aβ load to working memory (P =0.02 and 0.03, respectively).73

Comparing the biochemistry of AD and nondemented nonagenerians revealed the lack of clear amyloid-related pathological/ biochemical determination between both groups.74 A personal retrospective study of 100 nondemented elderly (mean age 81.23±5.47 years, mean Mini Mental State Examination (MMSE) score 29) revealed negative Khachaturian criteria Inhibitors,research,lifescience,medical and CERAD stage 0 in 83% and 86%, respectively, only 13% with CERAD stage A and 1% stage B. Braak neuritic stages ranged from 0 to IV with an average score of 2.3±0.8. 12% were scored NIA-RI low, and only 2% intermediate likelihood for AD.37 Thus, mounting evidence from clinicopathologic studies support the view Isotretinoin that AD is a continuous spectrum between asymptomatic lesions in cognitively normal elderly and dementia, with mild cognitive impairment (MCI) as a transition phase between them.75 Although correlations between cognitive check details deficits and the severity and extension of senile plaques (SP) and NFTs (see ref 42) have been found, at least in those brains without other pathologies, the distinction between “physiological” (in nondemented subjects) and “pathological” aging (PA) is difficult.
