Abstract
BACKGROUND Time-trend analyses of incidence and mortality in bleeding peptic ulcer show divergent results. AIM To conduct a detailed national analysis of hospitalisation of and mortality from bleeding peptic ulcer in Sweden. METHOD Data from all hospitalisations at departments with primary responsibility for patients with bleeding ulcer in Sweden, with main diagnosis or co-diagnosis of bleeding ulcer from 1987 to 2005 were retrieved from the Hospital Discharge Register. A validation study was performed due to an uncertainty in diagnostic setting after the introduction of ICD-10 in 1997. Annual hospitalisation rates per 100 000 inhabitants in relation to gender, age and ulcer location were calculated as well as age-standardised 30-day mortality rates. RESULTS Hospitalisations for bleeding ulcer decreased from 63.9 to 35.3 per 100 000 inhabitants per year during the study period. The decrease was greater among men (men: from 80.4 to 40.9; women: from 47.7 to 29.7) and in younger age groups. Bleeding gastric ulcer decreased in both genders, and bleeding duodenal ulcer decreased most among men, but was stable in a subgroup of elderly women. Median age increased from 70 to 76 years. Standardised 30-day mortality increased from 5.3% to 6.2%. The increased mortality was found in those aged more than 65 years and with duodenal ulcer disease, whereas mortality remained unchanged in those with bleeding gastric ulcer. CONCLUSION Hospitalisation rates for bleeding peptic ulcer have markedly decreased in Sweden in all age groups. The 30-day mortality is low compared with other nationwide studies in the western world, but has increased among patients with duodenal ulcer disease.

Abstract
OBJECTIVES Tongue volume reduction is an adjunct treatment in several orofacial orthopaedic procedures for various craniofacial deformities; it may affect structural reconstitution and functional recovery as a result of the repair process. The aim of this study was to investigate myogenic regeneration and structural alteration of the tongue following surgical tongue volume reduction. MATERIALS AND METHODS Five 12-week-old sibling pairs of Yucatan minipigs (three males and two females) were used. Midline uniform glossectomy was performed on one of each pair (reduction); siblings had identical incisions without tissue removal (sham). All pigs were raised for a further 4 weeks and received 5-bromo-2-deoxyuridine (BrdU) injection intravenously 1 day before killing. Tissue sections of tongues were stained with anti-BrdU antibody to evaluate numbers of replicating cells. Haematoxylin and eosin plus trichrome staining were performed to assess muscular structure. RESULTS Reduction tongues contained significantly more BrdU+ cells compared to sham tongues (P < 0.01). However, these BrdU+ cells were mostly identified in reparative connective tissues (fibroblasts) rather than in regenerating muscle tissue (myoblasts). Trichrome-stained sections showed disorganized collagen fibres linked to few intermittent muscle fibres in the reduction tongues. These myofibres presented signs of atrophy with reduced perimysium and endomysium. Matrix between reduced perimysium and endomysium was filled with fibrous tissue. CONCLUSIONS Fibrosis without predominant myogenic regeneration was the major histological consequence of surgical tongue volume reduction.

Abstract
BACKGROUND Causative gene mutations have been identified in about 2% of those with amyotrophic lateral sclerosis (ALS), often, but not always, when there is a strong family history. There is an assumption that there is a genetic component to all ALS, but genome-wide association studies have yet to produce a robustly replicated result. A definitive estimate of ALS heritability is therefore required to determine whether ongoing efforts to find susceptibility genes are worth while. METHODS The authors performed two twin studies, one population- and one clinic-based. The authors used structural equation modelling to perform a meta-analysis of data from these studies and an existing twin study to estimate ALS heritability, and identified 171 twin pairs in which at least one twin had ALS. RESULTS AND DISCUSSION Five monozygotic twin pairs were concordant-affected, and 44 discordant-affected. No dizygotic twin pairs were concordant-affected, and 122 discordant-affected. The heritability of sporadic ALS was estimated as 0.61 (0.38 to 0.78) with the unshared environmental component 0.39 (0.22 to 0.62). ALS has a high heritability, and efforts to find causative genes should continue.

Abstract
Overwhelming evidence supports a central role for the amyloid beta-peptide (Abeta) in the pathogenesis of Alzheimer's disease (AD), and the proteases that produce Abeta from its precursor protein APP are top targets for therapeutic intervention. Considerable effort has focused on targeting gamma-secretase, which generates the C-terminus of Abeta; however, gamma-secretase inhibitors cause serious toxicities due to interference with the Notch signaling pathway. We have been working toward compounds that directly alter gamma-secretase activity to reduce Abeta production without affecting the proteolysis of Notch. Using purified enzyme and substrate, we have shown that gamma-secretase can be selectively inhibited in this way by naphthyl-substituted gamma-aminoketones and gamma-aminoalcohols. These early hits, however, suffered from chemical instability and/or poor potency. Iterative design, synthesis and evaluation have led to the discovery of Notch-sparing gamma-secretase inhibitors with substantially increased potencies in biochemical and cellular assays. These compounds are of low molecular weight and are under evaluation for drug-like properties. The discovery and development of these compounds will be discussed.

Abstract
During July 2008, sandy loam soil samples were collected near the rhizosphere of Kentucky bluegrass (Poa pratensis L.) and tall fescue (Festuca arundinacea Schreb.) at a depth of 15 to 20 cm from Caledonia Park, Toronto, Canada. Samples were suspended in water and nematodes were collected on sieves with 250- and 74-μm openings. Among the nematodes recovered were one species of Longidorus Micoletzky, 1922 (4) and one species of Trichodorus Cobb, 1913. The Trichodorus species (2), was identified as T. primitivus (de Man, 1880) Micoletzky, 1922, in which females have rod-like sclerotized pieces parallel to the vagina lumen, each with dimensions of 3.1 × 1.2 μm and at a distance of 2 to 3 μm from each other; and males have spicules with a wide nonoffset capitulum and very narrow blade, three ventromedian cervical papillae (CP), and three precloacal supplements with the anterior one at the level of the capitulum of retracted spicules. Males showed unusual variation in the position of CP2 (i.e., posterior to the onchiostyle region, except for one specimen with CP2 located within the posterior onchiostyle region, which is typical for the species). The morphometric data for nine males are: L, 665 to 805 μm; a, 23.0 to 27.5; b, 3.7 to 5.2; c, 46 to 56; onchiostyle, 47 to 52 μm; and spicules, 32.5 to 40.5 μm. Measurements for 13 females are: L, 630 to 775 μm; a, 20.5 to 24.8; b, 3.5 to 5.5; c, 75.5 to 158.5; and V, 54 to 61%. To our knowledge, this is the first report of T. primitivus in Canada. According to Chen et al. (1), the Longidorus species was identified as L. elongatus (de Man, 1876) Micoletzky, 1922 (3). The morphometric data for females (n = 13) are: L, 5.1 to 6.0 mm; a, 78.5 to 106.5; b, 11.5 to 13.5; c, 86.0 to 120.5; V, 45.5 to 53.0%; odontostyle, 79 to 91 μm; odontophore, 57.5 to 66.5 μm; and tail length, 44.5 to 59.0 μm. Males were not found. Four juvenile stages were identified. J1 (n = 2) with a body length of 1.1, 1.2 mm and replacement/functional odontostyle 59, 59/53.5, 54.5 μm, J2 (n = 2) with L: 1.7, 2.0 mm and replacement/functional odontostyle 62.5, 68.0/58.7 μm, 59.0, J3 (n = 2): L: 2.8, 3.0 mm and replacement/functional odontostyle 76.5, 77/66.5, 67.0 μm and J4 (n = 2) with L: 3.6, 3.8 mm and replacement/functional odontostyle 87.0, 90.5/75.0, 77.5 μm. Due to large morphometric overlap in Longidorus species identification, 2,472 bp of the near full-length 18S and the internal transcribed spacer 1 region of rDNA (Accession No. GU199044) were sequenced. The Blastn search of the partial 18S revealed 100% identity with a population of L. elongatus from Scotland (GenBank No. AY687992, 1,707 bp compared), 99% identity (3 bp difference, 1,707 bp compared) with a population of L. elongatus from Iran (EU503141) and 99% identity (4 bp difference, 1,707 bp compared) with a population of L. elongatus (AF036594, sample location unknown). A Blastn search of the 18S and ITS region revealed only 1 to 3 bp differences with two populations of L. elongatus from Switzerland (AJ549986 and AJ549987) and a population of L. elongatus (AF511417) from Scotland. These molecular data further confirmed the identity of the population from Canada to be L. elongatus. References: (1) Q. Chen et al. Fundam. Appl. Nematol. 20:15, 1997. (2) W. Decraemer.

Abstract
Methyl protodioscin (MPD), a natural furostanol saponin, showed distinct antitumor activity and is distributed in many traditional Chinese medicines. The pharmacokinetics, distribution and excretion of MPD were first investigated after i.v. injection to rats in this study. The dose-dependent pharmacokinetics of MPD were characterized after i.v. injection (20, 40 and 120 mg/kg of MPD) to rats. A good linearity (r = 0.9989, P < 0.05) was found in the regression analysis of the AUC0-t -dose. The plasma concentrations of MPD declined rapidly with an elimination half-life (t1/2) from 25.56 to 29.32 min. The MPD kinetics was in line with one-compartment model after i.v. injection. 23.43% and 32.86% of MPD was recovered in urine and bile, respectively. The concentrations of MPD in plasma and most examined tissues 5 h after injection were close to or below the Low Limit of Quantification (LLOQ). This indicated that MPD was distributed and eliminated rapidly in rats.

Abstract
OBJECTIVE To investigate whether longitudinal declines in cognition are associated with higher fibrillar amyloid-beta (Abeta) deposition in vivo in individuals without dementia. METHOD [(11)C]PiB images were obtained to measure fibrillar Abeta burden in 57 participants without dementia from the Baltimore Longitudinal Study of Aging. Participants (33 men, 24 women) had a mean (SD) age of 78.7 (6.2) years. Six participants (4 men, 2 women) had mild cognitive impairment defined as Clinical Dementia Rating = 0.5. To measure [(11)C]PiB retention, distribution volume ratios (DVR) for 15 regions of interest were estimated by fitting a simplified reference tissue model to the measured time activity curves. Mixed effects regression was used to predict cognitive trajectories over time using data before and including time of PiB (mean follow-up 10.8 years), with mean cortical DVR, age at baseline, sex, and education as independent predictors. Voxel-based analysis identified local associations. RESULTS [(11)C]PiB retention was higher in older individuals. Greater declines over time in mental status and verbal learning and memory, but not visual memory, were associated significantly with higher PiB retention. Voxel-based analysis showed significant associations in frontal and lateral temporal regions. CONCLUSIONS Higher Abeta deposition is associated with greater longitudinal decline in mental status and verbal memory in the preceding years. The differential association for verbal but not visual memory may reflect the greater reliance of verbal word list learning on prefrontal regions, which show early Abeta deposition. Prospective imaging may help distinguish between individuals with evolving neuropathology who develop accelerated cognitive decline vs those with normal aging.

Abstract
Sera from chickens that consumed a known level of (-)-gossypol (-)-GP) exhibited bioactivity against human breast cancer cells in vitro. Based on this, it is conceivable that similar anti-breast cancer activities of different magnitudes will be exhibited in biological samples harvested from (-)-GP-fed layer hens. The experimental data generated in this study may influence the fundamental thinking regarding the utilization of low cost agricultural commodities such as (-)-GP cottonseed meal to produce value-added chemopreventive animal products.

Abstract
The change of cholinergic transmission of beta-amyloid protein (beta-AP) treated rats was studied by intracerebral microdialysis sampling combined with HPLC analysis. beta-AP(1-40) was injected into nucleus basalis magnocellularis (NBM). Passive avoidance response test (step-down test) and delayed alternation task were used for memory testing. The impairment of memory after injection of beta-AP(1-40) into NBM exhibited mainly the deficiency of short-term working memory. One week after injection of beta-AP(1-40) the release of acetylcholine (ACh) from frontal cortex of freely-moving rats decreased significantly, and the response of cholinergic nerve ending to the action of high [K(+)] solution was rather weak. In control animals the percentage of increase of ACh-release during behavioral performance was 57%, while in beta-AP(1-40)-treated rats it was 34%. The temporary increase of the ACh-release of the rat put into a new place was also significantly diminished in beta-AP(1-40) -treated rats. The results show that the injection of beta-AP(1-40) into NBM impairs the cholinergic transmission in frontal cortex, and the impairment of cholinergic transmission may be the main cause of the deficit of working memory.

Abstract
The objective of this study was to investigate the relationship between increased prevalence of cardiovascular disease and glucose regulation status in Chinese patients with metabolic syndrome (MetS). All patients underwent an oral glucose tolerance test (2-h post-load plasma glucose) to determine their glucose regulation status and had their brachial–ankle pulse wave velocity (baPWV) measured. Of the 590 patients included in the study, 115 (19.5%) had normal glucose tolerance, 114 (19.3%) had impaired fasting glucose (IFG) alone, 38 (6.4%) had impaired glucose tolerance (IGT) alone, 197 (33.4%) had diabetes mellitus and 126 (21.4%) had combined glucose intolerance (CGI; IFG plus IGT). Patients with diabetes mellitus had a significantly higher baPWV compared with all other groups and patients with CGI had a significantly higher baPWW compared with patients with IFG. Dysglycaemia was common in patients with MetS. An increased prevalence of cardiovascular disease in patients with MetS was related to their glucose regulation status.

Abstract
AIMS The aim was to examine the impact of Type 1 diabetes and having any other diabetes-related complication or comorbidity on healthcare charges and utilization in patients with diabetic neuropathy (DN). METHODS We selected individuals aged < 65 years who continuously enrolled in a large US commercial plan from July 2004 to June 2006 and who received at least one diagnosis of DN at any time from July 2004 to June 2005. We compared the prevalence of other diabetes-related complications or comorbidities between patients with Type 1 and with Type 2 diabetes. In patients with DN with or without any other diabetes-related complication or comorbidity, we used multivariate regression to assess the marginal contribution of Type 1 diabetes on healthcare charges and utilization from July 2005 until June 2006. RESULTS The majority of DN patients had at least one other diabetes-related complication or comorbidity. Most of the DN patients had Type 2 diabetes. DN patients with Type 1 diabetes had more comorbid medical conditions than those with Type 2 diabetes. Compared with Type 2, Type 1 patients had a higher prevalence of each individual non-DN diabetes-related complication or comorbidity, except heart disease. Controlling for comorbidities, Type 1 and Type 2 patients with DN but no other diabetes-related complication or comorbidity had similar healthcare utilization. However, Type 1 patients had significantly higher charges than those with any other diabetes-related complication or comorbidity. CONCLUSIONS Many patients with DN have Type 1 diabetes and other common diabetes-related complications or comorbidities, which can have a significant impact on healthcare charges and utilization.

Abstract
BACKGROUND The scientific evidence on whether long-term use of snuff is associated with high blood pressure is limited, inconsistent and based only on cross-sectional data. OBJECTIVE We aimed at studying the risk of hypertension in relation to long-term use of snuff based on longitudinal data. DESIGN Repeated health check-ups were offered to all employees in the Swedish construction industry between 1978 and 1993. Blood pressure was measured at the health check-up and information on tobacco use and other risk factors was collected through questionnaires. SETTING In total, 120 930 never smoking men with information on blood pressure and snuff use at baseline were included. The association of high blood pressure and snuff use at baseline was estimated by logistic regression. Further, 42 055 men were identified as normotensive at baseline and had at least one subsequent health check-up. Through repeated blood pressure measurements and linkage to the Swedish National Inpatient Register, information on hypertension was obtained. Relative risk estimates were derived from Cox proportional hazards regression model. RESULTS Almost 30% of all men had used snuff. The adjusted odds ratio of high blood pressure amongst snuff users at baseline was 1.23 (95% CI 1.15-1.33) compared to never snuff users. The relative risk of high blood pressure during follow-up was 1.39 (95% CI 1.08-1.79) amongst snuff users and 1.36 (95% CI 1.07-1.72) for hypertension as recorded in the Inpatient Register. CONCLUSION Use of Swedish moist snuff appears to be associated with a moderately increased risk of hypertension.

Abstract
BACKGROUND Patients with high-risk primary breast cancer remain at high risk for relapse. More precise prognostic and predictive tools are needed to improve treatment of such patients. PATIENTS AND METHODS Formalin-fixed, paraffin-embedded tumors from 239 high-risk breast cancer patients were examined for expression of human epidermal growth factor receptor 2 (HER2), epidermal growth factor receptor (EGFR), estrogen receptor, progesterone receptor, Ki-67, p16, p21, p27, and p53 by immunohistochemistry. Gene expression of EGFR, HER2, glutathione S-transferase-Pi (GSTP1), excision repair cross complementation1 (ERCC1), p21, beta-tubulin-3, multidurg resistance (MDR1), cyclooxygenase2 (COX2), and cyclin-E was measured by RT-PCR. RESULTS Eighty percent of patients presented with locally advanced, or > or =10 axillary nodal metastasis, and 20% with inflammatory breast cancer. The median age was 46 years (26-62 years) and the median number of involved axillary lymph nodes was 12 (0-42). At a median follow-up of 86 months, relapse-free survival (RFS) and overall survival for the entire group were 50% (95% CI 43% to 57%) and 62% (95% CI 56% to 69%). Multivariate Cox stepwise analysis resulted in a simple model for RFS consisting only of p21 expression, EGFR expression assessed by RT-PCR, and number of axillary nodal metastases. CONCLUSION A prognostic model on the basis of the expression of a limited number of proteins and genes may help to guide target-specific therapies in patients with high-risk breast cancer.
