Diagnosis and recommendation integrated system (DRIS) of soybean seed oil content

The Diagnosis and Recommendation Integrated System (DRIS) can improve interpretations of leaf analysis to determine the nutrient status. Diagnoses by this method require DRIS norms, which are however not known for oil content of soybean seeds. The aims of this study were to establish and test the DRIS method for oil content of soybean seed (maturity group II cultivars). Soybean leaves (207 samples) in the full flowering stage were analyzed for macro and micro-nutrients, and the DRIS was applied to assess the relationship between nutrient ratios and the seed oil content. Samples from experimental and farm field sites of the southernmost Brazilian state Rio Grande do Sul (28° - 29° southern latitude; 52° -53° western longitude) were assessed in two growing seasons (2007/2008 and 2008/2009). The DRIS norms related to seed oil content differed between the studied years. A unique DRIS norm was established for seed oil content higher than 18.68 % based on data of the 2007/2008 growing season. Higher DRIS indices of B, Ca, Mg and S were associated with a higher oil content, while the opposite was found for K, N and P. The DRIS can be used to evaluate the leaf nutrient status of soybean to improve the seed oil content of the crop.

Genetic and karyotypic structure in the shrews of the Sorex araneus group: are they independent?

The species of the common shrew (Sorex araneus) group are morphologically very similar but exhibit high levels of karyotypic variation. Here we used genetic variation at 10 microsatellite markers in a data set of 212 individuals mostly sampled in the western Alps and composed of five karyotypic taxa (Sorex coronatus, Sorex antinorii and the S. araneus chromosome races Cordon, Bretolet and Vaud) to investigate the concordance between genetic and karyotypic structure. Bayesian analysis confirmed the taxonomic status of the three sampled species since individuals consistently grouped according to their taxonomical status. However, introgression can still be detected between S. antinorii and the race Cordon of S. araneus. This observation is consistent with the expected low karyotypic complexity of hybrids between these two taxa. Geographically based cryptic substructure was discovered within S. antinorii, a pattern consistent with the different postglaciation recolonization routes of this species. Additionally, we detected two genetic groups within S. araneus notwithstanding the presence of three chromosome races. This pattern can be explained by the probable hybrid status of the Bretolet race but also suggests a relatively low impact of chromosomal differences on genetic structure compared to historical factors. Finally, we propose that the current data set (available at http://www.unil.ch/dee/page7010_en.html#1) could be used as a reference by those wanting to identify Sorex individuals sampled in the western Alps.

Chemoendocrine compared with endocrine adjuvant therapies for node-negative breast cancer: predictive value of centrally reviewed expression of estrogen and progesterone receptors--International Breast Cancer Study Group.

PURPOSE: To centrally assess estrogen receptor (ER) and progesterone receptor (PgR) levels by immunohistochemistry and investigate their predictive value for benefit of chemo-endocrine compared with endocrine adjuvant therapy alone in two randomized clinical trials for node-negative breast cancer. PATIENTS AND METHODS: International Breast Cancer Study Group Trial VIII compared cyclophosphamide, methotrexate, and fluorouracil (CMF) chemotherapy for 6 cycles followed by endocrine therapy with goserelin with either modality alone in pre- and perimenopausal patients. Trial IX compared three cycles of CMF followed by tamoxifen for 5 years versus tamoxifen alone in postmenopausal patients. Central Pathology Office reviewed 883 (83%) of 1,063 patients on Trial VIII and 1,365 (82%) of 1,669 on Trial IX and determined ER and PgR by immunohistochemistry. Disease-free survival (DFS) was compared across the spectrum of expression of each receptor using the Subpopulation Treatment Effect Pattern Plot methodology. RESULTS: Both receptors displayed a bimodal distribution, with substantial proportions showing no staining (receptor absent) and most of the remainder showing a high percentage of stained cells. Chemo-endocrine therapy yielded DFS superior to endocrine therapy alone for patients with receptor-absent tumors, and in some cases also for those with low levels of receptor expression. Among patients with ER-expressing tumors, additional prediction of benefit was suggested in absent or low PgR in Trial VIII but not in Trial IX. CONCLUSION: Low levels of ER and PgR are predictive of the benefit of adding chemotherapy to endocrine therapy. Low PgR may add further prediction among pre- and perimenopausal but not postmenopausal patients whose tumors express ER.

Panobacumab adjunctive immuno-therapy for Pseudomonas aeruginosa hospital-acquired pneumonia versus a cohort group

Objectives: To assess the efficacy of Panobacumab, a fully human IgM monoclonal antibody against P. aeruginosa serotype O11, by comparing a phase IIa trial with a standard care cohort trial both in hospital acquired pneumonia (HAP) caused by P. aeruginosa O11. Methods: Demographics, outcome and survival of HAP including Ventilator Associated Pneumonia (VAP) in patients either treated with standard antimicrobial therapy in a retrospective cohort trial (CT) or with adjunctive Panobacumab therapy during an open phase IIa trial were compared. Both trials applied the same inclusion exclusion criteria and the same trial period of 30 days. Results: 17 patients with VAP/HAP (14 / 3) caused by P. aeruginosa O11 were enrolled in a phase IIa trial (ITT population) and treated with Panobacumab, 13 of them received the full treatment course of 3 infusions (PP population, 12 VAP, 1 HAP) and 4 patients received only one infusion. In the cohort trial 14 patients (VAP/HAP: 12 / 2) treated with standard antibiotic therapy were included. The mean age and weight were 65.8 y (years) (SD 17.2) and 78.0 kg (SD 22.1) in the PP, 67.8 y (SD 15.4) and 77.1 kg (SD 20.2) in the ITT population and 51.8 y (SD 22.3) and 67.1 kg (SD 13.0) in the CT. At the time of suspicion of pneumonia a mean APACHE II and CPIS of 19.4 (13 - 33) and 8.7 (7 - 11) in the PP, 18.9 (13-33) and 8.5 (7 -11) in the ITT and 14.5 (2 - 24) and 7.5 (3 -12) in the CT population were observed. Tracheostomy was present in 53.8% and 52.9% in the PP and ITT populations and 38.4% in the CT. The pneumonia was polymicrobial in 69.2%, 70.6% and 85.7% in the PP, ITT and CT respectively. Stay at ICU and hospital before diagnosis of pneumonia were similar in the 3 groups. All 13 patients that received 3 doses of Panobacumab achieved resolution of pneumonia with only two relapsing during the study. Hence 85% achieved resolution and 15% recurrence at day 30. In the ITT group 64.7% of the pneumonia resolved 11.8% recurred and 23.5% continued while in the CT 57% resolved, 7% recurred and 34% continued. Resolution of pneumonia occurred markedly earlier in the Panobacumab trial (8.9 days, SD: 3.3) than in the cohort trial (15.3 days, SD: 9.5). The expected mortality derived from APACHE II score was 31% and 32% in the PP and ITT population and 22% in the cohort group. All patients who received 3 doses of Panobacumab survived, 18% died in the ITT group while in the CT 21% mortality matched the predicted mortality. Conclusions: Treatment of VAP/HAP caused by P. aeruginosa O11 with 3 doses of Panobacumab resulted in 100% survival, with highest pneumonia resolution (85%), and in a shorter time when compared with patients under standard therapy. The results indicate that Panobacumab may be effective in such life-threatening indication and warrants larger controlled trials.

Group 4: Career development for diverse and underserved populations

Globalization and diverse populations due to migration imply that counselors are expected to deliver career services to populations from a large array of cultural settings. Moreover, individuals belonging to minority or non-dominant groups may be underserved or misserved, thus decreasing their chances of finding employment opportunities through career counseling. To develop specific interventions minority or non-dominant groups, it seems important to understand their strength and weaknesses. These strengths and weaknesses will be presented in terms of risk and resilience factors, such as low future orientation and social support respectively. In the last two decades, several authors have made contributions to adapt and improve career services in order to best meet these minority groups' needs. A review of this literature identified thirteen keys to effective practice. For example, one key is to take responsibility for one's own biases and prejudices. Nonetheless, some underserved groups remain difficult to identify. Comparing some basic national demographic data with data from our counseling centers may be helpful in this context in identifying specific groups and assessing needs. One solution, in order to promote social justice across (all) cultural groups, is to encourage multiculturalism in both career counseling and society as a whole. A more inclusive society would allow each person in a minority or non-dominant group to contribute more effectively to the development and growth of this society.

Evaluation of the susceptibility of pathogenic Candida species to fluconazole. Fluconazole Global Susceptibility Study Group.

A fluconazole 25 microg disk diffusion test was used to test 2230 consecutively isolated Candida strains from 42 different hospital laboratories in 23 countries. Ninety seven percent of 1634 Candida albicans isolates and 83.4% of 596 non-Candida albicans isolates were susceptible to fluconazole, applying the proposed breakpoints (> or = 26 mm for susceptible strains and 18-25 mm for dose-dependent susceptible strains). This is the first hospital laboratory study to evaluate a large number and wide range of sequential Candida isolates from patients with all types of hospital infections. The fluconazole disk diffusion test appears to be a low-cost, reproducible, and accurate means of assessing the in vitro susceptibility of Candida isolates.

Chromosome localization of microsatellite markers in the shrews of the Sorex araneus group.

The extremely high rate of karyotypic evolution that characterizes the shrews of the Sorex araneus group makes this group an exceptionally interesting model for population genetics and evolutionary studies. Here, we attempted to map 46 microsatellite markers at the chromosome arm level using flow-sorted chromosomes from three karyotypically different taxa of the Sorex araneus group (S. granarius and the chromosome races Cordon and Novosibirsk of S. araneus). The most likely localizations were provided for 35 markers, among which 25 were each unambiguously mapped to a single locus on the corresponding chromosomes in the three taxa, covering the three sexual chromosomes (XY1Y2) and nine of the 18 autosomal arms of the S. araneus group. The results provide further evidence for a high degree of conservation in genome organization in the S. araneus group despite the presence of numerous Robertsonian rearrangements. These markers can therefore be used to compare the genetic structure among taxa of the S. araneus group at the chromosome level and to study the role of chromosomal rearrangements in the genetic diversification and speciation process of this group.

Realizations of Poincar group induced by second order differential systems. Non interaction theorem

A generalization of the predictive relativistic mechanics is studied where the initial conditions are taken on a general hypersurface of M4. The induced realizations of the Poincar group are obtained. The same procedure is used for the Galileo group. Noninteraction theorems are derived for both groups.

Genomewide association study of atazanavir pharmacokinetics and hyperbilirubinemia in AIDS Clinical Trials Group protocol A5202.

BACKGROUND: Atazanavir-associated hyperbilirubinemia can cause premature discontinuation of atazanavir and avoidance of its initial prescription. We used genomewide genotyping and clinical data to characterize determinants of atazanavir pharmacokinetics and hyperbilirubinemia in AIDS Clinical Trials Group protocol A5202. METHODS: Plasma atazanavir pharmacokinetics and indirect bilirubin concentrations were characterized in HIV-1-infected patients randomized to atazanavir/ritonavir-containing regimens. A subset had genomewide genotype data available. RESULTS: Genomewide assay data were available from 542 participants, of whom 475 also had data on estimated atazanavir clearance and relevant covariates available. Peak bilirubin concentration and relevant covariates were available for 443 participants. By multivariate analysis, higher peak on-treatment bilirubin levels were found to be associated with the UGT1A1 rs887829 T allele (P=6.4×10), higher baseline hemoglobin levels (P=4.9×10), higher baseline bilirubin levels (P=6.7×10), and slower plasma atazanavir clearance (P=8.6×10). For peak bilirubin levels greater than 3.0 mg/dl, the positive predictive value of a baseline bilirubin level of 0.5 mg/dl or higher with hemoglobin concentrations of 14 g/dl or higher was 0.51, which increased to 0.85 with rs887829 TT homozygosity. For peak bilirubin levels of 3.0 mg/dl or lower, the positive predictive value of a baseline bilirubin level less than 0.5 mg/dl with a hemoglobin concentration less than 14 g/dl was 0.91, which increased to 0.96 with rs887829 CC homozygosity. No polymorphism predicted atazanavir pharmacokinetics at genomewide significance. CONCLUSION: Atazanavir-associated hyperbilirubinemia is best predicted by considering UGT1A1 genotype, baseline bilirubin level, and baseline hemoglobin level in combination. Use of ritonavir as a pharmacokinetic enhancer may have abrogated genetic associations with atazanavir pharmacokinetics.
