Abstract
Anecdotal beliefs that exercise is an effective treatment for primary dysmenorrhoea have prevailed for many years although evidence is contradictory. Previous studies have also contained a number of methodological inadequacies. A questionnaire that assessed menstrual pain and levels of exercise was administered to 654 university students. Attempts were made to blind the purpose of the study. A response rate of 91.3% (597/654) was obtained. Analyses showed no association between participation in exercise and primary dysmenorrhoea. Prospective studies would be useful in further research.

Abstract
e19518 Background: Waldenstrom's macroglobulinemia (WM) is a rare lymphoplasmacytic lymphoma. More sensitive tools of tumor burden and prognosis are needed in these patients (pts). The use of FDG-PET has not been previously studied in WM but has proved an effective diagnostic and prognostic tool effective in low-grade lymphomas. Therefore the objective of this study was to determine whether FDG-PET was an effective tool in evaluating pts with WM. Methods: We included all pts enrolled on a prospective phase II clinical trial of bortezomib and rituximab for pts with upfront or relapsed/refractory (RR) WM. All pts were CD20 positive with histologically confirmed disease and underwent staging evaluation by FDG-PET in combination with CT scan before and after therapy. Patients received 6 cycles of bortezomib IV weekly at 1.6mg/m2 on days 1, 8, 15q28 and rituximab at 375 mg/m2 on days 1, 8, 15 and 22 in cycles 1 and 4. Correlation was made with the international prognostic scoring system for WM and monoclonal protein response rate. Results: 53 pts were included, of which 35 were RR and 18 pts were upfront. Median age was 63 years (range 42–81), 64% were male. Before therapy, 34 pts (64.2%) had positive FDG-PET findings with a median IgM of 2825, Beta 2 microglobulin of 3.6, and Age of 61. 36 pts showed a minor response or greater with a correlation to negative PETs after therapy. Conclusions: Over 60% of WM pts demonstrated FDG-avid disease when using FDG-PET scans, with the majority showing negative disease after therapy. This correlates with the 67.9% response rate. Positive PET images were inversely correlated to IgM level and directly related to elevated Beta-2 microglobulin and age. Significantly PET positive individuals may demonstrate a poorer prognosis. FDG-PET scans may prove an effective tool in the diagnosis and prognosis in WM. [Table: see text]

Abstract
8535 Background: This phase II study aimed to determine safety and activity of weekly bortezomib in combination with rituximab in patients with relapsed/refractory Waldenstrom macroglobulinemia (WM). Methods: Patients who had at least one previous therapy for WM and who had relapsed or refractory disease were eligible. NCI CTCAE v3.0 was used for toxicity assessment. All patients received bortezomib IV weekly at 1.6mg/m2 on days 1, 8, 15, q 28 days × 6 cycles, and rituximab 375 mg/m2 at days 1, 8, 15, 22, on cycles 1 and 4. Results: 37 pts (26 men and 11 women, median age 62 years, range 42 - 73) have been treated to date. The median number of lines of prior treatment was 3 (range 1 - 5). All patients had received prior rituximab and 5 pts received prior bortezomib. The median IgM at baseline was 3540 mg/dL (range 700-10,800). The median follow up is 12 months (range 5 - 26 months). Thirty-five pts are evaluable for response. Complete remission and near complete remission occurred in 2 (6%), partial remission in 17 (48%), and minimal response in 10 (29%). Progressive disease occurred in 1 (3%) and stable disease occurred in 5 (14%). Most patients achieved response rapidly within 3 months of therapy (2–7 months). Rituximab flare occurred only in 6 patients (20%). At 24 months of follow up, 8/35 pts have shown relapsed disease. The median time to progression and duration of response has not been reached. Patients tolerated therapy well without significant toxicities: grade 3 peripheral neuropathy occurred in only 2 pts. Grade 1 and 2 neuropathy occurred in 10 pts (26%). Other grade 3 and 4 toxicities included neutropenia in 5 patients, and anemia and thrombocytopenia in 4 patients. Grade 5 pneumonia and viral infection occurred in 1 patient who was within the first cycle of therapy and did not receive herpes zoster prophylaxis. Attributable toxicities otherwise proved manageable with appropriate supportive care and the combination was generally well tolerated. Conclusions: The combination of weekly bortezomib and rituximab has been well tolerated and demonstrates encouraging activity, with CR+ PR + MR in 83% of evaluable patients with relapsed WM. No significant peripheral neuropathy has been observed to date with this regimen. [Table: see text]

Abstract
The European Union Water Framework Directive (WFD) requires a good chemical and ecological status of European surface waters by 2015. Integrated, risk-based management of river basins is presumed to be an appropriate approach to achieve that goal. The approach of focusing on distinct hazardous substances in surface waters together with investment in best available technology for treatment of industrial and domestic effluents was successful in significantly reducing excessive contamination of several European river basins. The use of the concept of chemical status in the WFD is based on this experience and focuses on chemicals for which there is a general agreement that they should be phased out. However, the chemical status, based primarily on a list of 33 priority substances and 8 priority hazardous substances, considers only a small portion of possible toxicants and does not address all causes of ecotoxicological stress in general. Recommendations for further development of this concept are 1) to focus on river basin-specific toxicants, 2) to regularly update priority lists with a focus on emerging toxicants, 3) to consider state-of-the-art mixture toxicity concepts and bioavailability to link chemical and ecological status, and 4) to add a short list of priority effects and to develop environmental quality standards for these effects. The ecological status reflected by ecological quality ratios is a leading principle of the WFD. While on the European scale the improvement of hydromorphological conditions and control of eutrophication are crucial to achieve a good ecological status, on a local and regional scale managers have to deal with multiple pressures. On this scale, toxic pollution may play an important role. Strategic research is necessary 1) to identify dominant pressures, 2) to predict multistressor effects, 3) to develop stressor- and type-specific metrics of pressures, and 4) to better understand the ecology of recovery. The concept of reference conditions to define the ecological status is hard to apply and tends to ignore the fact that ecosystems can be highly dynamic. A better understanding of ecosystem responses to changes as well as early warning systems and concepts sensitive to various stressors to discriminate disturbances from natural variation are required. Because ecosystems are closely interconnected, an integrated monitoring, diagnosis, and stressors-based management of the whole water, sediment, groundwater, soil, and air system is required considering land use and the interaction with a changing climate. Extending this holistic approach beyond a consideration of existing pressures by anticipating on future ones to use and protect the aquatic environment in a sustainable way is one of the big challenges.

Abstract
Understanding the host response to Mycobacterium avium subsp. paratuberculosis is critical to the development of effective vaccines and therapeutics for the control of this disease in the field. The current study compared the effectiveness of oral and intraperitoneal (IP) methods of experimental inoculation and two strains of M. avium subsp. paratuberculosis (strain K-10 and clinical isolate 509) on the level of infection and lesion development. Calves were inoculated with 4x10(11) to 8x10(12)cfu live bacteria, depending upon treatment group. Fecal shedding of M. avium subsp. paratuberculosis was minimal and infrequent over the course of the study for calves that received strain K-10 (oral and IP), however, calves orally inoculated with the clinical isolate shed high numbers of bacteria in their feces up to 4 months post-inoculation. Colonization was present in a number of intestinal tissues and lymph nodes with the lowest number of affected tissues in the IP calves and the highest for calves receiving the clinical isolate via oral inoculation. Microscopic lesions were predominantly found in the ileal and jejunal sections of small intestine and their associated lymph nodes, as well as the ileocecal valve and node. These data suggest that a variety of experimental infection regimes can be effective but oral inoculation with a clinical isolate may result in greater colonization of tissues and fecal shedding of M. avium subsp. paratuberculosis.

Abstract
BACKGROUND Chromosomal abnormalities frequently are associated with impairment or arrest of spermatogenesis in mammals but are compatible with fertility in female carriers of the same anomaly. In the case of trisomy, mice have extra genomic DNA as well as the chromosomal abnormality, usually present as an extra, unpaired chromosome. Thus, impairment of spermatogenesis in trisomic males could be due to the presence of extra genomic material (i.e. triplicated genes) or due to the chromosomal abnormality and presence of an unpaired chromosome in meiosis. METHODS In this study, fertility and chromosomal pairing configurations during meiotic prophase were analysed in male mice trisomic for different segments of the genome. Four have an extra segmental or tertiary trisomic chromosome--Ts(17(16))65Dn, Ts(10(16))232Dn, Ts(12(17))4Rk and Ts(4(17))2Lws--and one has the triplicated segment attached to another chromosome--Ts(16C-tel)1Cje. Ts(17(16))65Dn and Ts(16C-tel)1Cje have similar gene content triplication and differ primarily in whether the extra DNA is in an extra chromosome or not. RESULTS The presence of an intact extra chromosome, rather than trisomy per se, is associated with male sterility. Additionally, sterility is correlated with a high frequency of association of the unpaired chromosome with the XY body, which contains the largely unpaired X and Y chromosomes. CONCLUSIONS Intact extra chromosomes disrupt spermatogenesis, and unpaired chromosomes establish a unique chromatin territory within meiotic nuclei.

Abstract
BACKGROUND Pyrexia is common after brain injury; it is generally believed to affect outcome adversely and the usual clinical methods of reducing temperature are not effective. The normal physiological mechanisms of brain cooling are heat loss from the upper airways and through the skull, and these can produce selective brain cooling. METHODS Air at room temperature and humidity was continuously administered to 15 brain-injured, intubated and mechanically ventilated patients via a sponge-tipped oxygen catheter in each nostril at a combined rate of 115 ml kg(-1) min(-1). Brain temperature was measured using a pressure-temperature Camino catheter which is designed to site the thermistor 1 cm into the parenchyma in the frontal lobe. Oesophageal temperature was measured using an oesophageal stethoscope with a thermistor. After establishing baseline for 30 min, patients were randomized to receive airflow or no airflow for 6 h and then crossed over for a further 6 h. RESULTS Airflow replicating normal resting minute volume did not produce clinically relevant or statistically significant reductions in brain temperature [0.13 (SD 0.55) degrees C; 95% CI, 0.43-0.17 degrees C]. However, we serendipitously found some evidence of selective brain cooling via the skull, but this needs further substantiation. CONCLUSIONS A flow of humidified air at room temperature through the upper respiratory tracts of intubated brain-injured patients did not produce clinically relevant or statistically significant reductions in brain temperature measured in the frontal lobe.

Abstract
Thyroid peroxidase antibodies (TPOAb) in pregnancy are a marker for postpartum (PPTD) and long-term thyroid dysfunction, with variable sensitivity and specificity in PPTD prediction. To test its utility in prediction, we recruited 308 TPOAb-positive (147 developed PPTD (PPTD group) and 161 remained euthyroid [PPTE group]) and 102 TPOAb-negative women (none developed PPTD), in early pregnancy (median, 18; range, 9-19 weeks' gestation). TPOAb levels were higher in the PPTD group (median) (125.2 kIU/L; p < 0.001), and in its hypothyroid (162.4 kIU.; p < 0.0001), hyperthyroid (114.2 kIU/L; p < 0.007), and biphasic (105.1 kIU/L; p < 0.02) variants, compared to the PPTE group (66.7 kIU/L) The incidence of PPTD was significantly higher with TPOAb levels above 58.2 kIU/L (early pregnancy versus postpartum; relative risk, 1.37 [95% confidence interval [CI] 1.17-1.61] versus 0.78 [95% CI 0.5-1.2]) compared to levels below. The integrated postpartum TPOAb response was higher in the PPTD group (median) (159 kIU/L per week) and its variants (hypothyroid; 199 kIU/L per week; biphasic, 180 kIU/L per week; hyperthyroid, 120 kIU/L per week), compared to the PPTE group (86 kIU/L per week p < 0.004). Median early pregnancy TPOAb levels in the PPTD and PPTE groups correlated well with the postpartum antibody response (r = 0.58, p < 0.001). The sensitivity of TPOAb in PPTD prediction was 100% (early pregnancy and postpartum), specificity 62% (early pregnancy) versus 41% (postpartum) and positive predictive value 48% (early pregnancy and postpartum). The timing of TPOAb testing, the sensitive assay used and the absence of PPTD in TPOAb-negative subjects contributed to this high sensitivity. We recommend TPOAb in early pregnancy as a useful predictor of PPTD, particularly in populations where PPTD does not occur in TPOAb-negative women.

Abstract
Since the sequencing of the first two chromosomes of the malaria parasite, Plasmodium falciparum, there has been a concerted effort to sequence and assemble the entire genome of this organism. Here we report the sequence of chromosomes 1, 3-9 and 13 of P. falciparum clone 3D7--these chromosomes account for approximately 55% of the total genome. We describe the methods used to map, sequence and annotate these chromosomes. By comparing our assemblies with the optical map, we indicate the completeness of the resulting sequence. During annotation, we assign Gene Ontology terms to the predicted gene products, and observe clustering of some malaria-specific terms to specific chromosomes. We identify a highly conserved sequence element found in the intergenic region of internal var genes that is not associated with their telomeric counterparts.
