Antimicrobial-Resistant Enteric Bacteria from Dairy Cattle

ABSTRACT A study was conducted to understand the descriptive and molecular epidemiology of antimicrobial-resistant gram-negative enteric bacteria in the feces of healthy lactating dairy cattle. Gram-negative enteric bacteria resistant to ampicillin, florfenicol, spectinomycin, and tetracycline were isolated from the feces of 35, 8, 5, and 42% of 213 lactating cattle on 74, 39, 9, 26, and 82% of 23 farms surveyed, respectively. Antimicrobial-resistant gram-negative bacteria accounted for 5 (florfenicol) to 14% (tetracycline) of total gram-negative enteric microflora. Nine bacterial species were isolated, of which Escherichia coli (87%) was the most predominant species. MICs showing reduced susceptibility to ampicillin, ceftiofur, chloramphenicol, florfenicol, spectinomycin, streptomycin, and tetracycline were observed in E. coli isolates. Isolates exhibited resistance to ampicillin (48%), ceftiofur (11%), chloramphenicol (20%), florfenicol (78%), spectinomycin (18%), and tetracycline (93%). Multidrug resistance (≥3 to 6 antimicrobials) was seen in 40% of E. coli isolates from healthy lactating cattle. Of 113 tetracycline-resistant E. coli isolates, tet(B) was the predominant resistance determinant and was detected in 93% of isolates, while the remaining 7% isolates carried the tet(A) determinant. DNA-DNA hybridization assays revealed that tet determinants were located on the chromosome. Pulsed-field gel electrophoresis revealed that tetracycline-resistant E. coli isolates (n = 99 isolates) belonged to 60 subtypes, which is suggestive of a highly diverse population of tetracycline-resistant organisms. On most occasions, E. coli subtypes, although shared between cows within the herd, were confined mostly to a dairy herd. The findings of this study suggest that commensal enteric E. coli from healthy lactating cattle can be an important reservoir for tetracycline and perhaps other antimicrobial resistance determinants.
Determination of absorption coefficients for concentrated samples by fluorescence detection.

A method to determine the absorption coefficient near the onset of core-electron transitions for concentrated samples using fluorescence-yield (FY) detection is presented. Measuring the FY signal for different experimental geometries, we are able to calculate the true absorption coefficient. Thus wve are able to correct fully for saturation effects present in FY spectra of concentrated samples. The technique is demonstrated for Co and a buried layer of CoSi 2
Influence of mastitis on growth of starter organisms used for the manufacture of fermented milks

Summary The effect of milk containing increased somatic cells on the starter organisms Streptococcus thermophilus, Lactobacillus bulgaricus and L. acidophilus was examined. Increased somatic cell count resulted in stimulation of Str. thermophilus owing to increased proteolysis, but inhibition of L. acidophilus as a consequence of increased phagocytic activity of the polymorphonuclear leucocytes
The Extended Thin-Wire Model of Lossy Round Wire Structures for FDTD Simulations

This paper presents an extended thin-wire model for simulating lightning surge or wave propagation on lossy round wire structures. The wire structures are represented with time-domain cascade circuits, and are integrated into a traditional finite-difference time-domain (FDTD) thin-wire model for the simulation. The model for solid round conductors, cylindrical tubes, and coaxial conductors is provided, and the skin effect is fully considered. In the coaxial structure, the currents in both inner and outer conductors are not necessarily balanced. The proposed model has been validated analytically and numerically, and good agreements have been observed. It has been applied to analyze lightning current sharing in a lossy radio-frequency coaxial cable. Compared with the traditional FDTD method, this extended thin-wire model requires less memory space and computation time in the simulation.
N-[(4-Amino-5-sulfanylidene-4,5-dihydro-1H-1,2,4-triazol-3-yl)methyl]-4-methylbenzamide

In the title compound, C11H13N5OS, the dihedral angle between the triazole ring and the benzene ring is 84.21 (7)°. The amino group adopts a pyramidal configuration. An intramolecular N—H⋯O hydrogen bond stabilizes the molecular structure and generates an S(8) ring. In the crystal, molecules are linked by intermolecular N—H⋯O, N—H⋯S, N—H⋯N and C—H⋯S hydrogen bonds into layers lying parallel to the bc plane. The crystal structure is further stabilized by aromatic π–π stacking interactions [centroid–centroid distance = 3.3330 (7) Å].
The Harbaugh Effect: A Spike in Michigan Allegiance Displays in a City with Divided Loyalty

This manuscript discusses coalitional behavior from an ethological perspective and tests a hypothesis regarding displays of group allegiance using observational methods. Tinbergen’s Four Questions (T4Q; Tinbergen, 1963) is a powerful explanatory framework for building a comprehensive understanding of behavior in humans and other species. Following T4Q, coalitional behavior is examined regarding evolutionary adaptiveness, phylogenetic history, proximate causation, and developmental ontogeny. Team sports are an intuitive domain for the illustration of patterns and principles in coalitional behavior. Athletic team loyalty is often communicated non-verbally though the display of apparel and paraphilia featuring university or team names and logos. Previous research documented increases in apparel displays after winning games. Toledo, Ohio is on the Michigan-Ohio border and was originally considered within Michigan Territory. The area contains a mixture of Ohio State University (OSU) and University of Michigan (UM) football fans and merchandise featuring each school is widely available. An observational study in the Fall 2013 collegiate football season found a ratio of approximately 3:2 for individuals displaying OSU and UM branded items. The hiring of Jim Harbaugh as Michigan’s new head coach in 2015 was expected to generate an increase in displays of UM branded items. Observations in the 2015 and 2016 seasons found equivalent rates of display for UM and OSU branded items, and a significant increase in displays of UM branded items from 2013.
The Experience of Living With a Family Member With Challenging Behavior Post Acquired Brain Injury

ABSTRACT Acquired brain injury (ABI) can be a sudden, dramatic, and, sometimes, fatal event that instantly disrupts the lives of the patients and their families. Healthcare professionals and families are being confronted with the long-term effects of ABI. This article presents a descriptive phenomenological study that aimed to explore the families' meaning of living with the cognitive, emotional, and behavioral sequelae of ABI survivors. In-depth, face-to-face, semistructured interviews were conducted with a purposive sample of five family members of ABI survivors who displayed challenging behavior. Data collected were analyzed using A. Giorgi's (1985) descriptive phenomenological method of data analysis. Analysis and descriptions from the five participants revealed seven interrelated themes; one theme described the challenging behaviors of the people with ABI, and six themes described the experiences of the family members (emotional turmoil that these behaviors engendered, a profound sense of loss, concerns for their future and for the future of the person with ABI, a sense of loneliness, the effect on family functioning, and the family members' coping and adapting to the behaviors). This study contributes to healthcare providers' understanding and knowledge of families' experiences of living with a person with ABI and their cognitive, emotional, and behavioral sequelae and supports the need for continued research in this area.
Stressful life-events, anxiety, depression and coping in patients of irritable bowel syndrome.

UNLABELLED A lot of research has pointed to a complex interaction between stressful life events, psychiatric morbidity and the irritable bowel syndrome (IBS). AIM The present study aimed to determine the: stressful life-events in patients with irritable bowel syndrome patients in comparison to normal controls; effect of these events in causing clinically significant anxiety and depression; and the effect of psychopathology i.e. anxiety and depression on coping skills in these patients. METHODOLOGY Thirty patients with irritable bowel syndrome were compared with thirty matched normal controls, on the presumptive stressful life events scale and the mechanisms of coping scale. Further, among the irritable bowel syndrome patient group, the anxious and depressed subgroups were separated from the non-anxious and non-depressed subgroups using the hospital anxiety and depression scale. Positive and negative coping mechanisms between these subgroups were compared. RESULTS Significantly higher stress scores were found in the irritable bowel syndrome patient group than normal controls. Not all, but slightly more than fifty percent of irritable bowel syndrome had definite and clinically significant anxiety and/or depression. Those IBS patients with either definite depression tended to use predominantly negative coping styles as compared to those IBS patients without anxiety or depression. CONCLUSION Stressful life-event scores are significantly higher in IBS patients than in normal controls. Although not all of these patients have anxiety and/or depression, a significant number of patients show evidence of the same. Presence or absence of anxiety and/or depression influences how the patient with IBS copes with illness. Therefore, though further studies on the issue are required, we suggested that, as a supplement to medical management, recognition and treatment of anxiety and depression in this subgroup of IBS patients with psychotropic drugs and cognitive therapy for gaining more positive coping skills, may require special attention in the management of irritable bowel syndrome.
Gel Shift and UV Cross-linking Analysis of Tetrahymena Telomerase (*)

Telomerase is an unusual ribonucleoprotein that synthesizes new telomeres onto chromosome ends. The enzyme has been most extensively characterized in ciliates, where the RNA component has been cloned from several species, and its elongation properties have been characterized in detail. To understand the substrate specificity and protein composition of telomerase, we have used gel shift and UV cross-linking to characterize the enzyme from the ciliate Tetrahymena thermophila. In a mobility shift assay, a complex was identified that contained telomerase RNA, co-purified with telomerase activity, and was sensitive to nuclease treatment. The mobility shift complexes specifically formed using several different single-stranded, telomeric sequences but not non-telomeric primers. These results suggest that the specificity of telomerase for G-rich primer sequences occurs at least in part at the level of primer binding. UV cross-linking analysis identified a 100-kDa cross-linked protein that may be a telomerase component.
FMS 2014 Formal Methods for Security Proceedings of the Formal Methods for Security Workshop A Satellite Event of Petri Nets 2014

Du-Vote is a new remote electronic voting protocol that eliminates the often-required assumption that voters trust general-purpose computers. Trust is distributed in Du-Vote between a simple hardware token issued to the voter, the voters’s computer, and a server run by election authorities. Verifiability is guaranteed with statistically high probability even if all these machines are controlled by the adversary, and privacy is guaranteed as long as at least either the voter’s computer or the server is not controlled by the adversary. The design of the Du-Vote protocol is presented in this paper. A new non-interactive zero-knowledge proof is employed to verify the server’s computations. The security of the protocol is analyzed to determine the extent to which, when components of the system are malicious, privacy and verifiability are maintained.
Juvenile Huntington disease in an 18‐month‐old boy revealed by global developmental delay and reduced cerebellar volume

Juvenile Huntington disease (JHD) is a rare clinical entity characterized by disease onset before the age of 21. JHD accounts for <10% of Huntington disease patients. Transmission of JHD is paternal in 80–90% of cases. Patients with JHD usually carry more than 60 CAG repeats within the HTT gene. We report here on a 23‐month‐old boy presenting with global developmental delay first noted at 18 months of age. Clinical examination showed truncal hypotonia, postural and intentional tremor, limb rigidity, and ataxia. Cerebral magnetic resonance imagery (MRI) showed reduced cerebellar volume. Six months later, his 47‐year‐old father was seen for a 4‐year history of progressive dementia with severe behavioral disturbance and chorea. Cerebral MRI showed discrete global and caudate atrophy. DNA analysis revealed a very large and heterogeneous expansion (210–250 CAG) in the child and a 43 CAG expansion of the HTT gene in the father. This unusual case demonstrates that very early onset JHD due to large CAG expansions should be considered in cases of global developmental delay associated with reduced cerebellar volume, including cases without known HD family history. © 2011 Wiley‐Liss, Inc.
p19ARF Is Dispensable for Oncogenic Stress-Induced p53-Mediated Apoptosis and Tumor Suppression In Vivo

ABSTRACT Recent studies have shown the p19ARF tumor suppressor to be involved in the response to oncogenic stress by regulating the activity of p53. This response is mediated by antagonizing the function of Mdm2, a negative regulator of p53, indicating a pathway for tumor suppression that involves numerous genes altered in human tumors. We previously described a transgenic mouse brain tumor model in which oncogenic stress, provided by cell-specific inactivation of the pRb pathway, triggers a p53-dependent apoptotic response. This response suppresses the growth of developing tumors and thus represents a bona fide in vivo tumor suppressor activity. We further showed that E2F1, a transcription factor known to induce p19ARF expression, was required for the response. Here, we use a genetic approach to test whether p19ARF functions to transduce the signal from E2F1 to p53 in this tumor suppression pathway. Contrary to the currently accepted hypothesis, we show that a deficiency in p19ARF has no impact on p53-mediated apoptosis or tumor suppression in this system. All measures of p53 function, including the level of apoptosis induced by pRb inactivation, the expression of p21 (a p53-responsive gene), and the rate of tumor growth, were comparable in mice with and without a functional p19ARF gene. Thus, although p19ARF is required in some cell types to transmit an oncogenic response signal to p53, it is dispensable for this function in an in vivo epithelial system. These results underscore the complexity of p53 tumor suppression and further indicate the existence of distinct cell-specific pathways that respond to similar stimuli.
Differential physiological effects of Raf-1 kinase pathways linked to protein kinase C activation depending on the stimulus in v-H-ras-transformed cells.

PURPOSE We investigated the molecular mechanism by which the Raf-1 kinase pathways that are linked to protein kinase C induce differential physiological effects, depending on the stimulus, by employing the pharmacological PKC activator PMA. MATERIALS AND METHODS Parental and v-Ha-ras transfected NIH 3T3 cells were chosen as test systems and these cells were transiently transfected with the pMTH vector that encodes dominant-negative (DN) PKC-epsilon with using Lipofectamine 2000. The cell proliferation reagent WST-1 was used for the quantitative determination of cellular proliferation. The Raf-1 kinase activity was measured by assessing the phosphorylation of recombinant MEK with using the immunoprecipitated Raf-1 proteins. The phosphorylated MEK protein bands were quantified by using Quantity One analysis software. RESULTS The pharmacological PKC activator phorbol-12-myristate-13-acetate (PMA) and platelet-derived growth factor (PDGF) were able to induce the activation of Raf-1 kinase in the v-H-ras-transformed NIH3T3 fibroblasts. However, PMA was found to be much less sensitive PI3 kinase inhibitor or the chemical antioxidant than is PDGF. Especially, PMA mediated growth arrest while PDGF induced mitogenic signaling through the PKC-epsilon activation. Thus, the regulation of the Raf-1 cascade by both PDGF and PMA is likely to be intimately linked and they converge at the PKC level through different upstream pathways, as was shown by the inhibition of PDGF-induced Raf-1 kinase activation by the transient transfection with a dominant-negative mutant of PKC-epsilon. CONCLUSIONS Taken together, these results imply that, depending on the stimulus, Raf-1 kinase leads to different physiological effects.
Current Status on Cholangiocarcinoma and Gallbladder Cancer

Background: Cholangiocarcinomas (CC) as well as gallbladder cancers are relatively rare and intractable diseases. Clinical, pathological, and epidemiological studies on these tumors have been under investigation. The current status and/or topics on biliary tract cancers have been reported in the East West Association of Liver Tumor (EWALT), held in Milano, Italy in 2015. Summary: All the authors, herein, specifcally reported the current status and leading-edge findings on biliary tract cancers as the following sequence: epidemiology of CC, surgical therapy for intrahepatic CC, surgical therapy for perihilar CC, surgical therapy for gallblad der cancer, chemotherapy for biliary tract cancers, and new histological features in CC. Key Message: The present review article will update the knowledge on biliary tract cancers, en hancing the quality of daily clinical practice. However, many features about these cancers remain unknown; further studies are required to establish disease-specific optimal treatment strategies.
Bevacizumab in non-small-cell lung cancer: a review

Current targeted strategies for cancer focus on the blockade of growth factor receptors and the inhibition of angiogenesis. The VEGF pathway has become an attractive target in multiple malignancies, including lung cancer. Bevacizumab, a monoclonal antibody against VEGF, increased survival in non-small-cell lung cancer (NSCLC) patients when added to standard carboplatin/paclitaxel chemotherapy. The pivotal Phase III study (ECOG 4599) in NSCLC showed longer overall survival: 12.3 versus 10.3 months and a higher median progression-free survival of 6.2 versus 4.5 months when chemotherapy was associated with bevacizumab. Benefits were confirmed in terms of progression-free survival in the European Phase III study (AVAiL). Subsequently, bevacizumab gained US FDA and European Medicines Agengy approval as a first-line therapy for advanced NSCLC. Bevacizumab’s safety profile is well established: most adverse events are mild to moderate and can be managed using standard interventions. This article presents an overview of the current data on bevacizumab for NSCLC.
Effect of azole antifungal therapy on vincristine toxicity in childhood acute lymphoblastic leukemia.

10049 Background: Vincristine is one of the corner stitches in the treatment of children with acute lymphoblastic leukemia (ALL). Constipation and other peripheral and central neurotoxicities are the most common side effects. Drugs interfering with the metabolism of vincristine might potentiate these side effects. A group of drugs that interact with the metabolism of vincristine are azoles. Several case reports suggest that co-administration of azoles and vincristine lead to increased toxicity. A comparative study exploring toxicity in patients receiving vincristine with and without azoles, is lacking. For this reason, we retrospectively analyzed neurotoxicity induced by vincristine with (n = 20) and without (n = 20) co-administration of azoles in the same patient group. METHODS In total, twenty pediatric patients with de novo ALL were included in this study. Vincristine toxicity was graded retrospectively according to the National Cancer Institute toxicity scale without information considering comedication. Statistical analysis was performed using the Wilcoxon Signed Rank test and McNemar test. RESULTS Patients receiving vincristine in combination with prophylactic azole treatment experienced significantly more complaints of constipation and peripheral neurotoxicity (P = 0.001 and P< 0.001, respectively). Three patients (15%) treated with azole therapy developed severe toxicity and needed treatment at the pediatric intensive care unit. Vincristine induced CNS toxicity (convulsions, toxic encephalopathy and SIADH) was seen in 6 patients (30%). All these patients were treated with vincristine in combination with an azole. CNS toxicity was not observed in patients receiving vincristine alone (P = 0 .014). Because of severe toxicities, vincristine treatment was significantly reduced (50% of normal dose) in several patients. CONCLUSIONS This study shows that vincristine toxicity is significantly increased when combined with azole treatment and even can be life threatening. Therefore we advise to avoid the combination of azole and vincristine treatment in patients with ALL. No significant financial relationships to disclose.
PATTERNS OF FUNDUS AUTOFLUORESCENCE DEFECTS IN NEOVASCULAR AGE-RELATED MACULAR DEGENERATION SUBTYPES

Purpose: To test define characteristic fundus autofluorescence patterns of different exudative age-related macular degeneration subtypes. Methods: Cross-sectional study. Fifty-two patients with choroidal neovascularization because of three different neovascular age-related macular degeneration subtypes were included in the study. Macular and peripheral fundus autofluorescence patterns of study subjects were compared in a masked fashion. Results: Fundus autofluorescence patterns of all three neovascular age-related macular degeneration subtypes revealed similar patterns. However, peripapillary hypo-autofluorescence was more common among patients with polypoidal choroidal vasculopathy (88.2%) compared with patients with retinal angiomatous proliferation (12.5%) and patients without retinal angiomatous proliferation and polypoidal choroidal vasculopathy (21.1%) (P < 0.0001). Conclusion: Presence of peripapillary fundus autofluorescence defects in neovascular age-related macular degeneration maybe suggestive of polypoidal choroidal vasculopathy as a variant of neovascular age-related macular degeneration.
