Abstract
To understand further the role of deoxynivalenol (DON) in development of Fusarium head blight (FHB), we investigated effects of the toxin on uninfected barley tissues. Leaf segments, 1 to 1.2 cm long, partially stripped of epidermis were floated with exposed mesophyll in contact with DON solutions. In initial experiments with the leaf segments incubated in light, DON at 30 to 90 ppm turned portions of stripped tissues white after 48 to 96 h. The bleaching effect was greatly enhanced by addition of 1 to 10 mM Ca(2+), so that DON at 10 to 30 ppm turned virtually all stripped tissues white within 48 h. Content of chlorophylls a and b and of total carotenoid pigment was reduced. Loss of electrolytes and uptake of Evans blue indicated that DON had a toxic effect, damaging plasmalemmas in treated tissues before chloroplasts began to lose pigment. When incubated in the dark, leaf segments also lost electrolytes, indicating DON was toxic although the tissues remained green. Thus, loss of chlorophyll in light was due to photobleaching and was a secondary effect of DON, not required for toxicity. In contrast to bleaching effects, some DON treatments that were not toxic kept tissues green without bleaching or other signs of injury, indicating senescence was delayed compared with slow yellowing of untreated leaf segments. Cycloheximide, which like DON, inhibits protein synthesis, also bleached some tissues and delayed senescence of others. Thus, the effects of DON probably relate to its ability to inhibit protein synthesis. With respect to FHB, the results suggest DON may have multiple roles in host cells of infected head tissues, including delayed senescence in early stages of infection and contributing to bleaching and death of cells in later stages.

Abstract
Abstract
Background: Ductal carcinoma in-situ (DCIS) on core needle biopsy (CNB) may be associated with a final diagnosis of invasive cancer (IC). As patients with IC need axillary assessment, those at risk of upstaging may be appropriate for sentinel node biopsy (SNB) at initial surgery, preventing the need for re-operation. We assessed this risk using pre-operative factors to develop a management algorithm.Materials and Methods: All patients whose CNB showed DCIS or DCIS with microinvasion (DCISm) from a single population-based breast screening program in Australia between 1994 and 2006 were studied. Medical records were reviewed for demographic, radiologic, clinical and pathologic data.Results: 11 of 15 DCISm cases (73.3%) and 65 of 375 DCIS cases (17.3%) were upstaged to IC. Microinvasion on CNB overwhelmingly predicted presence of frank invasive cancer. For cases of DCIS, multivariate analysis showed that (1) palpability (p=0.009), (2) large mammographic size ≥20mm (p=0.001) and (3) prolonged screening interval ≥3 years (p=0.008) were associated with upstaging. On univariate analysis, (4) non-calcific mammographic features (mass, architectural distortion or non-specific density) were significantly associated with upstaging (p=0.001). There was a trend towards upstaging in patients with high grade DCIS on CNB (p=0.07). Factors not associated with upstaging were microcalcifications (p=0.12), comedonecrosis (p=0.14), age (p=0.38) and CNB method (p=0.50). The rate of upstaging increases with the number of associated risk factors present in a patient: 8.3% in patients with no risk factors, 21.2% in those with one risk factor, 38.6% in those with two risk factors, and 52.9% in those with three risk factors. 13 patients (3.3%) had lymph node metastases.Conclusions: The risk of upstaging can be estimated using pre-operative features in patients with DCIS on CNB. We propose a management algorithm that includes SNB for DCIS patients: with microinvasion on core biopsy, with two or more predictive factors, and those with planned total mastectomy.

Abstract
A patient developed fever, chills, and shortness of breath after an elective first trimester dilation and curettage. Blood cultures grew Group B streptococcus, and a transesophageal echocardiogram revealed a 2 x 2 cm vegetation on the tricuspid valve and global left ventricular hypokinesis. A 6-week course of parenteral antibiotics and vasodilator therapy resulted in resolution of the valvular vegetation as well as of the left ventricular dysfunction.

Abstract
The equine industries in Ireland are vibrant and growing. They are broadly classified into two sectors: Thoroughbred racing, and sports and leisure. This paper describes these sectors in terms of governance, education and training in equine welfare, and available data concerning horse numbers, identification, traceability and disposal. Animal welfare, and specifically equine welfare, has received increasing attention internationally. There is general acceptance of concepts such as animal needs and persons' responsibilities toward animals in their care, as expressed in the 'Five Freedoms'. As yet, little has been published on standards of equine welfare pertaining to Ireland, or on measures to address welfare issues here. This paper highlights the central role of horse identification and legal registration of ownership to safeguard the health and welfare of horses.

Abstract
Automatic segmentation of cell nuclei is critical in several high-throughput cytometry applications whereas manual segmentation is laborious and irreproducible. One such emerging application is measuring the spatial organization (radial and relative distances) of fluorescence in situ hybridization (FISH) DNA sequences, where recent investigations strongly suggest a correlation between nonrandom arrangement of genes to carcinogenesis. Current automatic segmentation methods have varying performance in the presence of nonuniform illumination and clustering, and boundary accuracy is seldom assessed, which makes them suboptimal for this application. The authors propose a modular and model-based algorithm for extracting individual nuclei. It uses multiscale edge reconstruction for contrast stretching and edge enhancement as well as a multiscale entropy-based thresholding for handling nonuniform intensity variations. Nuclei are initially oversegmented and then merged based on area followed by automatic multistage classification into single nuclei and clustered nuclei. Estimation of input parameters and training of the classifiers is automatic. The algorithm was tested on 4,181 lymphoblast nuclei with varying degree of background nonuniformity and clustering. It extracted 3,515 individual nuclei and identified single nuclei and individual nuclei in clusters with 99.8 +/- 0.3% and 95.5 +/- 5.1% accuracy, respectively. Segmented boundaries of the individual nuclei were accurate when compared with manual segmentation with an average RMS deviation of 0.26 microm (approximately 2 pixels). The proposed segmentation method is efficient, robust, and accurate for segmenting individual nuclei from fluorescence images containing clustered and isolated nuclei. The algorithm allows complete automation and facilitates reproducible and unbiased spatial analysis of DNA sequences.

Abstract
BACKGROUND Extracapsular tumor spread (ECS) has been identified as a possible risk factor for breast cancer recurrence, but controversy exists regarding its role in decision making for regional radiotherapy. This study evaluates ECS as a predictor of local, axillary, and supraclavicular recurrence. PATIENTS AND METHODS International Breast Cancer Study Group Trial VI accrued 1475 eligible pre- and perimenopausal women with node-positive breast cancer who were randomly assigned to receive three to nine courses of classical combination chemotherapy with cyclophosphamide, methotrexate, and fluorouracil. ECS status was determined retrospectively in 933 patients based on review of pathology reports. Cumulative incidence and hazard ratios (HRs) were estimated using methods for competing risks analysis. Adjustment factors included treatment group and baseline patient and tumor characteristics. The median follow-up was 14 years. RESULTS In univariable analysis, ECS was significantly associated with supraclavicular recurrence (HR = 1.96; 95% confidence interval 1.23-3.13; P = 0.005). HRs for local and axillary recurrence were 1.38 (P = 0.06) and 1.81 (P = 0.11), respectively. Following adjustment for number of lymph node metastases and other baseline prognostic factors, ECS was not significantly associated with any of the three recurrence types studied. CONCLUSIONS Our results indicate that the decision for additional regional radiotherapy should not be based solely on the presence of ECS.

Abstract
PURPOSE To describe the prevalence and nature of epileptic seizure disorders in a typical UK prison and compare the care offered to prisoners to the recommendations of the National Institute for Clinical Excellence (NICE). METHODS Over a 14-month period, all prisoners identified as having epilepsy were registered by prison primary healthcare services at a category 'C' prison holding 640 male adults. Prison and National Health Service health records were reviewed, prisoners were re-assessed by members of a specialist secondary care service based in the local general hospital NHS. RESULTS Twenty-six prisoners were thought to have epilepsy. 61.5% of diagnoses had not been made by epilepsy specialists, 73.1% had uncontrolled seizures, only 19.2% had had computed tomography, none magnetic resonance imaging. At review, 30.8% of prisoners were thought to require neuroimaging, 19.2% cardiac investigations. The diagnosis of epilepsy was confirmed in only 57.9% of those prisoners considered to have the condition by prison healthcare services. 53.8% of those prisoners confirmed as having epilepsy had not had a medical review in the past 12 months; 63.2% required a change in their antiepileptic drugs (AEDs). CONCLUSION Although the prevalence of epilepsy in this prison population appeared high at first sight, a critical review of the diagnoses reduced the difference to the prevalence of epilepsy in the population at large. Fewer prisoners than expected achieved seizure control. Collaboration with specialist epilepsy services was poor. There were significant discrepancies between the healthcare provision in prison and the NICE epilepsy guidelines.

Abstract
BACKGROUND Bromocriptine improves hyperprolactinemic amenorrhea and so could also be helpful in the treatment of unexplained subfertility in women. OBJECTIVES To assess the effects of bromocriptine in women with unexplained subfertility. SEARCH STRATEGY The Cochrane Subfertility Review Group specialised register of controlled trials was searched. SELECTION CRITERIA Randomised trials comparing bromocriptine with placebo or no treatment in women with unexplained subfertility. DATA COLLECTION AND ANALYSIS Two reviewers applied the eligibility criteria and assessed trial quality independently. MAIN RESULTS Three trials involving of 127 women were included. All trials were double-blind comparisons with placebo, and one was of crossover design. Conception rates with bromocriptine treatment did not improve compared with placebo (odds ratio was 1.12, 95% confidence interval 0.48 to 2.57). AUTHORS' CONCLUSIONS There is not enough evidence to evaluate bromocriptine use in women with unexplained subfertility. However trials for women with unexplained subfertility who also have expressible galactorrhea may be worthwhile.

Accelerated titration design used, 1 patient (pt)/cohort entered until a single pt has dose-limiting toxicity (DLT) or 2 pts exhibit grade (gr) = 2 toxicity during the first cycle. The study then converts to a standard 3–6 pt/cohort design. Maximum tolerated dose (MTD): Dose at which no more than 1/6 pts have DLT and the dose below which at least 2/6 patients have DLT. Objectives: Determine toxicity profile, pharmacokinetics (PK), and MTD of CDDO. PK were determined by LC-MS/MS analysis of plasma collected pre, during and post CDDO infusion. Results: 6 pts have been accrued thus far up to dose level 6. (19.2 mg/m2). Diagnoses: colon -3, sarcoma-1, bladder -1 and ovary-1. Median age: 52. DLT and MTD have not yet been achieved. Gr 1–2 toxicities have been acceptable: anemia, thrombocytopenia, decreased Na+, Mg++ and albumin, elevated Ca++, transaminases and bilirubin, and anorexia, fatigue and constipation. Gr 4 pulmonary emboli (unrelated to CDDO) was seen in one pt. PK: Steady state CDDO plasma concentrations (Css) in the first 3 dose levels increased linearly (see table ). Post infusion CDDO plasma concentrations decreased in a bi- exponential manner for the first three dose levels. Data indicate that < 1% of CDDO is excreted in the urine unchanged. No oxidative metabolism has been observed; however, we identified a CDDO glucuronide conjugate in urine and in human liver tissue incubations in vitro. Conclusions: The DLT and MTD have not been reached, and accelerated dose escalation continues. Since the CDDO Css appears to increase linearly with dose, we anticipate achieving 1 μM plasma levels at dose level 5 (9.6mg/m2/hr), the effective concentration in preclinical models.

Abstract
Abnormal bleeding is a significant health problem, especially during adolescence and before menopause when anovulatory cycles are common. Curettage is rarely necessary to investigate or treat menstrual problems in adolescents, and its use should also be minimized in women younger than 40 years. In every age group, medical treatment is the initial choice, but surgical treatment by endometrial destruction or hysterectomy is sometimes required. Benign causes of bleeding include fibroids and possibly adenomyosis, but the indications for treatment in each case depend upon the extent of bleeding, not the extent of the lesion. Breakthrough bleeding (BTB) with combined oral contraceptives commonly leads to discontinuation of the method. As BTB tends to improve with time, in the first 3 months of pill use, unless there are obvious underlying causes, women should be reassured that it will likely settle. BTB is often the reason for discontinuing progestogen-only contraception, and there is a need for effective means of treating unscheduled bleeding. Bleeding occurs in approximately 3% of post-menopausal women, and the use of hormones increases the likelihood of bleeding by >5-fold. Knowledge of the underlying mechanisms of bleeding is essential to the development of effective treatment.

Abstract
BACKGROUND Major sources of morbidity and mortality in patients with tuberous sclerosis who develop subependymal giant cell astrocytomas (SEGAs) relate to tumor growth and resultant hydrocephalus. We describe a modification of a specialized minimal access resection technique in which an operative corridor is formed with balloon dilation over the course of a week prior to tumor resection. METHODS Three patients with tuberous sclerosis who had an enlarging SEGA and concomitant hydrocephalus underwent surgical resection with this modified technique. A frontal craniotomy was performed and the optimal trajectory for tumor resection was confirmed by image guidance. After initial insertion of the deflated balloon into the ventricle and removal of the peel-away sheath, inflation of the balloon with a 1-mL saline injection sealed the tract. Additional 1-mL saline injections were continued during the next week until the balloon reached a 15-mm diameter, thus creating the operative corridor. One week after the first operation, the balloon was deflated and removed, and the patient underwent tumor resection via the newly formed operative corridor. RESULTS Three patients with tuberous sclerosis underwent gross total resections of SEGAs and experienced subsequent resolution of ventricular dilation. Postoperative imaging confirmed minimal cortical disruption. CONCLUSIONS Use of balloon dilation for the gradual formation of an operative corridor eliminated the need for additional retraction during SEGA resection, potentially decreasing injury to the surrounding neural tissue. In our three patients, the dilation tract retained its integrity during the operation and had sealed completely on postoperative imaging.

Abstract
We present flow induced admittance spectra for electrolytes, cell culture media, different sizes of DNA solutions and neural cells using flow induced admittance spectra in a microfluidics device. The device comprises of a PDMS channel aligned with a pair of channel electrodes fabricated on glass. The peak of the flow induced admittance spectra and frequency at which the peak occurs are the key parameters used for the characterization of sensing. The response of this sensor is a function of the conductivity and dielectrivity of the effective solution. The flow induced admittances of the particles studied are corrected with their media. This sensing will be a primary component of an electrical based cytometer.

Abstract
The objective of this study was to determine the presence and magnitude of seasonal fluctuations in semen quality and other reproductive indices in bison bulls. Testicles from 288 commercially slaughtered bison bulls were collected monthly over a 1-year period. Carcass and testicle weight were determined and measurements of seminiferous tubule lumen, diameter, and epithelial thickness were made. Sperm cell morphology and defects were described and quantified using epididymal semen from each testicle. Twenty-one Plains (Bison bison bison) and Wood bison (Bison bison athabascae) breeding bulls, averaging 6.0 years of age (range 2.5-8.0), from three farms were selected for semen collection and evaluation on the basis of producer co-operation. Semen was collected by electro-ejaculation on four seasonal occasions during a 12-month period. Ejaculate quality was judged on the basis of volume, density, gross and individual motility, morphology, live/dead ratio, and concentration. Sperm cell morphologies were evaluated microscopically and classified according to criteria used for bovine semen. Fecal testosterone was measured at each semen collection using a commercial competitive binding radioimmunoassay. There was an increase in carcass weights over the study period and testis weights were moderately correlated (r=0.44) with carcass weights. However, mean testes weights were heavier (P<0.05) in the summer than in winter, spring, or fall periods. There were no differences in the proportion of normal and abnormal epididymal sperm between seasons but there were seasonal changes in the testicular parenchyma. Seminiferous tubule and lumen diameter, and epithelial thickness were greatest (P<0.05) in summer. Live bulls gained weight between April and November, but lost weight over the winter. Normal sperm cell percentages as well as individual sperm cell motility in electro-ejaculated sperm samples were higher (P<0.05) at the pre-breeding collection relative to other collections, but no change in sperm cell concentrations occurred over the study period. Fecal testosterone concentrations were highest at the pre-breeding period (June) but decreased (P<0.05) in each subsequent collection to reach their lowest levels in the April. While many changes in seen characteristics were not significant, overall results indicate the presence of some reproductive seasonality and increased testicular capacity in the summer breeding season. Bulls showing marginal semen quality in the winter but otherwise carrying desirable genetic traits may warrant another evaluation in late spring prior to being culled from a breeding program.

Abstract
BACKGROUND We evaluated the ability of CA15-3 and alkaline phosphatase (ALP) to predict breast cancer recurrence. PATIENTS AND METHODS Data from seven International Breast Cancer Study Group trials were combined. The primary end point was relapse-free survival (RFS) (time from randomization to first breast cancer recurrence), and analyses included 3953 patients with one or more CA15-3 and ALP measurement during their RFS period. CA15-3 was considered abnormal if >30 U/ml or >50% higher than the first value recorded; ALP was recorded as normal, abnormal, or equivocal. Cox proportional hazards models with a time-varying indicator for abnormal CA15-3 and/or ALP were utilized. RESULTS Overall, 784 patients (20%) had a recurrence, before which 274 (35%) had one or more abnormal CA15-3 and 35 (4%) had one or more abnormal ALP. Risk of recurrence increased by 30% for patients with abnormal CA15-3 [hazard ratio (HR) = 1.30; P = 0.0005], and by 4% for those with abnormal ALP (HR = 1.04; P = 0.82). Recurrence risk was greatest for patients with either (HR = 2.40; P < 0.0001) and with both (HR = 4.69; P < 0.0001) biomarkers abnormal. ALP better predicted liver recurrence. CONCLUSIONS CA15-3 was better able to predict breast cancer recurrence than ALP, but use of both biomarkers together provided a better early indicator of recurrence. Whether routine use of these biomarkers improves overall survival remains an open question.

Abstract
This systematic review and meta-analysis aimed to answer the following clinical question: among patients treated for IVF with gonadotrophins and GnRH analogues, is the probability of live birth per randomized patient dependent on the type of analogue used? Eligible studies were randomized controlled trials (RCTs), published as a full manuscript in a peer-reviewed journal, that contained sufficient information to allow ascertainment of whether randomization was true and whether equality was present between the groups compared. A literature search identified 22 RCTs comparing GnRH antagonists and GnRH agonists that involved 3176 subjects. Where live birth was not reported in a study that fulfilled the inclusion criteria, an effort was made to contact the corresponding authors to retrieve the missing information. If this was not possible, the reported outcome measure, clinical pregnancy or ongoing pregnancy was converted to live birth in 12 studies using published data (Arce et al., 2005). No significant difference was present in the probability of live birth between the two GnRH analogues [odds ratio (OR), 0.86; 95% confidence intervals (CI), 0.72 to 1.02]. This result remains stable in subgroup analysis that ordered the studies by type of population studied, gonadotrophin type used for stimulation, type of agonist protocol used, type of agonist used, type of antagonist protocol used, type of antagonist used, presence of allocation concealment, presence of co-intervention and the way the information on live birth was retrieved. In conclusion, the probability of live birth after ovarian stimulation for IVF does not depend on the type of analogue used for pituitary suppression.

Abstract
AIMS To ascertain the clinical and electrophysiological features in patients with juvenile neuronal ceroid lipofuscinosis (jNCL/Batten disease) and to identify those features that facilitate early diagnosis. METHODS Nine patients with jNCL were identified retrospectively and their case notes reviewed. All had undergone an extensive clinical examination, including electrophysiology. Blood and molecular genetic testing confirmed the diagnosis. RESULTS Age at onset ranged from 4-8 years. At presentation, two of nine patients had normal fundi; only two of nine patients had a bull's eye maculopathy. The electroretinogram (ERG) findings in this series included undetectable rod specific ERGs, an electronegative maximal response, reduced and delayed cone flicker ERGs, reduction in the b:a ratio in the photopic single flash ERG, and an undetectable pattern ERG. Vacuolated lymphocytes on peripheral blood film testing were present in eight of nine patients. Five of eight patients were homozygous for the 1.02 kb deletion on the CLN3 gene on molecular genetic testing; two of eight patients were heterozygous for that deletion. CONCLUSION jNCL should be considered in children of 10 years and under presenting with visual loss and fundal changes ranging from normal through to pigmentary/atrophic changes or a bull's eye maculopathy. Electrophysiology may suggest jNCL. Although currently untreatable, early diagnosis is important to institute appropriate counselling and support.

Abstract
BACKGROUND We sought to determine whether a high-risk group could be defined among patients with operable breast cancer in whom a search of occult central nervous system (CNS) metastases was justified. PATIENTS AND METHODS We evaluated data from 9524 women with early breast cancer (42% node-negative) who were randomized in International Breast Cancer Study Group clinical trials between 1978 and 1999, and treated without anthracyclines, taxanes, or trastuzumab. We identified patients whose site of first event was CNS and those who had a CNS event at any time. RESULTS Median follow-up was 13 years. The 10-year incidence (10-yr) of CNS relapse was 5.2% (1.3% as first recurrence). Factors predictive of CNS as first recurrence included: node-positive disease (10-yr = 2.2% for > 3 N+), estrogen receptor-negative (2.3%), tumor size > 2 cm (1.7%), tumor grade 3 (2.0%), < 35 years old (2.2%), HER2-positive (2.7%), and estrogen receptor-negative and node-positive (2.6%). The risk of subsequent CNS recurrence was elevated in patients experiencing lung metastases (10-yr = 16.4%). CONCLUSION Based on this large cohort we were able to define risk factors for CNS metastases, but could not define a group at sufficient risk to justify routine screening for occult CNS metastases.
