description: The dextransucrase gene from Weissella confusa Cab3, having an open reading frame of 4.2 kb coding for 1,402 amino acids, was amplified, cloned, and expressed in Lactococcus lactis. The recombinant dextransucrase, WcCab3-rDSR was expressed as extracellular enzyme in M17 medium with a specific activity of 1.5 U/mg which after purification by PEG-400 fractionation gave 6.1 U/mg resulting in 4-fold purification. WcCab3-rDSR was expressed as soluble and homogeneous protein of molecular mass, approximately, 180 kDa as analyzed by SDS-PAGE. It displayed maximum enzyme activity at 35°C at pH 5.0 in 50 mM sodium acetate buffer. WcCab3-rDSR gave Km of 6.2 mM and Vm of 6.3 µmol/min/mg. The characterization of dextran synthesized by WcCab3-rDSR by Fourier transform infrared and nuclear magnetic resonance spectroscopic analyses revealed the structural similarities with the dextran produced by the native dextransucrase. The modeled structure of WcCab3-rDSR using the crystal structures of dextransucrase from Lactobacillus reuteri (protein data bank, PDB id: 3HZ3) and Streptococcus mutans (PDB id: 3AIB) as templates depicted the presence of different domains such as A, B, C, IV, and V. The domains A and B are circularly permuted in nature having (β/α)8 triose phosphate isomerase-barrel fold making the catalytic core of WcCab3-rDSR. The structure superposition and multiple sequence alignment analyses of WcCab3-rDSR with available structures of enzymes from family 70 GH suggested that the amino acid residue Asp510 acts as a nucleophile, Glu548 acts as a catalytic acid/base, whereas Asp621 acts as a transition-state stabilizer and these residues are found to be conserved within the family.

description: Urban lakes are important assets to highly populated regions; however, extensive usage and other influences degrade their water quality, which then requires rehabilitation and maintenance. Hyper-eutrophic Swan Lake, Greater Toronto, Canada (5.5 ha, 4.4 m maximum depth) was a gravel pit that became degraded by elevated total phosphorus (TP) concentrations, mostly from internal P sources. Because Swan Lake is a terminal lake with limited flushing and small external load, a phosphate adsorbing and sediment capping agent, lanthanum-modified bentonite (Phoslock), was applied in spring 2013 to intercept the internal load. Average TP concentration decreased from 0.247 to 0.099 mg/L in the first and 0.060 mg/L in the second post-treatment year. A TP mass balance model adequately predicted post-treatment annual average TP concentration by not including the pre-treatment internal load estimate of 650 to 1100 mg/m2/yr. Phytoplankton biomass decreased only in the second post-treatment year, when Secchi transparency (highly correlated with chlorophyll concentration) increased to a growing season average of 1.4 m (range 0.7–2.7) compared to 0.5 m (0.37–0.63) before treatment. We explain the lack of response in the first treatment year with a relatively late application (29 Apr–1 May 2013), when P released from the winter bottom sediments had already been taken up by phytoplankton. Recently, a growing population of waterfowl (mostly Canada goose, Branta canadensis) were the highest contributors of nutrients (75%), as indicated by a mass balance based on literature-derived goose P export and biweekly bird census. We recommend waterfowl management or repeated treatment to further improve water quality.

description: A diverse range of novel and highly functionalized flavonoid-based tanaproget hybrids were synthesized and evaluated in vitro for their antimicrobial and antiproliferative activities. Novel products were synthesized in good yields (81–95%) under Pd-catalyzed reaction from bromo flavones and tanaproget boronic acids within 18–20 min at 60 °C. Bioassay results exhibited excellent activities against both hormone-dependent and hormone-independent human breast cancer cells (MCF-7, MDA-MB-231, DU-145, PC-3, and HeLa). Among them, compounds 4e, 9a, 9c, 9e, 9 g, 9 h, 9 m, and 9n displayed excellent activity. Compounds 4d, 4o, and 9o were found equally potent against C. albicans compared to fluconazole. Compound 5c showed better antibacterial activity against S. aureus. Compounds 5a, 9i, 9o, and 10c have shown admirable antibacterial activity against E. coli.

description: A sustained-release ivermectin bolus which is available in Canada and European countries (IVOMEC® SR Bolus) has been proved efficient for the treatment and prevention of nematodes in growing beef and dairy cattle. However, its effect on growth in breeding age dairy heifers has not been demonstrated, which leaves practitioners in doubt in regions where heifers are often confined until breeding age and then turned to pasture.

description: A facile approach for the syntheses of regioselective meso- mono, di (cis and trans), and tri formylthien-2-ylporphyrins from meso-tetrathien-2-ylporphyrin (ThP) is presented. The synthesized meso- mono formylthien-2-ylporphyrin ThP-CHO was further functionalized to 5-((5-terpyridinyl)thien-2-yl)-10,15,20-tris(thien-2-yl)porphyrin (ThP-TPy) and Porphyrin-Corrole (Por-Cor) dyad. The influence of formyl substitution and further functionalization on meso- thien-2-yl ring(s) with porphyrin central π-system is examined through UV–Vis absorption, 1H NMR spectroscopy and electrochemical studies. The red shift of Soret band and Q bands in the absorption spectrum and the redox potentials are shown to be dependent on the number of substitution (ThP-CHO, 424 nm < ThPt-(CHO)2 and ThPc-(CHO)2, 425 nm < ThP(CHO)3, 427 nm). The significant variation in redox potentials and distinct bathochromic shift in the absorption bands in the series of formyl derivatives, ThP-TPy and Por-Cor dyad have been explained based on the near-planar orientation of the meso-thienyl groups with the porphyrin core.

Year: 1997

description: Approximately 100,000 dairy cows are culled from dairy herds enrolled in milk recording through Ontario Dairy Herd Improvement (DHI) each year. The impact that these animals have on herd performance parameters, through their inclusion or exclusion, has been well established. As each cow removal is recorded, the producer is asked to designate one of 13 potential reasons for the cull. Once a year, a summary of all removals, including the removal reason and the days in milk (DIM) at removal, is provided to each producer. Questions have been raised about the utility of the removal report, and the validity of the information that it contains. The objective of this retrospective study was to validate, if possible, the reasons for removal and to suggest alternative strategies to recording and reporting dairy herd removal information.

description: Sulfonic acid-supported vanillin/bis indolylmethane-functionalized Fe3O4@SiO2-Propyl NPs were prepared and characterized by FT-IR, XRD, FE-SEM, TEM, VSM, EDX, DLS, and TGA-DTG. The catalytic efficiency of the prepared nanoparticles was subsequently investigated for the effective synthesis of imidazoquinazolines via the one-pot condensation of 2-aminobenzimidazole, aryl aldehydes, and cyclohexanone or dimedone under solvent-free condition. Some thiazoquinazolines also were prepared via the multicomponent reaction of aldehydes, dimedone, and 2-aminobenzothiazol under solvent-free condition,. This avenue is really suitable because it makes a high yield of product, doesn’t take too long, doesn’t need harmful materials and solvents, its work-up is easy and the catalyst is reusable.

description: We have described the catalytic activities of dicalcium phosphate dihydrate (DCPD) in the condensation reaction of various substituted benzaldehydes with active methylene compound malononitrile. The influences of reaction conditions on the corresponding catalytic behavior have been investigated. The results showed that the DCPD exhibited high catalytic activity and versatility and that it can be recycled without significant loss of its activity for the condensation reactions, which shows the material is a promising new type of heterogeneous catalyst for the condensation reactions. Meanwhile, the catalytic results of DCPD compared favorably with those of other materials for Knoevenagel reactions reported previously.

description: As the North American dairy industry prepares for increased global competition, there is a growing interest in the recording of cattle health data, pertaining to diseases of economic significance. These data are needed to further investigate the genetic component of disease occurrence and resistance, to describe, compare and investigate disease occurrence on a national and regional basis, to modify management practices that promote animal health, and to monitor the health status of the national dairy herd. A major impediment to this initiative is the lack of national standards for disease definition and presentation. To deal with the confusion over mastitis case definition, the International Dairy Federation has recently proposed international guidelines for the recording and presentation of mastitis data.

description: Dextransucrase gene from Weissella confusa Cab3, having an open reading frame of 4.2 kb coding for 1402 amino acids, was amplified, cloned and expressed in Lactococcus lactis. The recombinant dextransucrase, WcCab3-rDSR was expressed as extracellular enzyme in M17 medium with a specific activity of 1.5 U/mg which after purification by PEG-400 fractionation gave 6.1 U/mg resulting in 4 fold purification. WcCab3-rDSR expressed as soluble and homogeneous protein of molecular mass, approximately, 180 kDa as analysed by SDS-PAGE. It displayed maximum enzyme activity at 35°C at pH 5.0 and at 50 mM in sodium acetate buffer. WcCab3-rDSR gave Km of 6.2 mM and Vm of 6.3 µmol/min/mg. The characterization of dextran synthesized by WcCab3-rDSR by FT-IR and NMR spectroscopic analyses revealed the structural similarities with the dextran produced by the native dextransucrase. The modeled structure of WcCab3-rDSR by using the crystal structures of dextransucrase from Lactobacillus reuteri (pdb id: 3HZ3) and Streptococcus mutans (pdb id: 3AIB) as templates depicted the presence of different domains such as A, B, C, IV and V. The domains A and B are circularly permuted in nature having (β/α)8 “TIM” barrel fold making the catalytic core of WcCab3-rDSR. The structure superposition and MSA analysis of WcCab3-rDSR with available structures of enzymes from family 70 GH suggested that the amino acid residue Asp510 acts as a nucleophile, Glu548 act as a catalytic acid/base, whereas, Asp621 acts as a transition state stabilizer and these residues found to be conserved within the family.

Year: 1997

description: Hairy heel warts remain a major concern for dairy producers because of the effect on milk yield. Field test procedures have been developed for the evaluation of hairy wart treatment products. Potential treatment products are applied daily using a garden sprayer after pre-washing the affected area with water. Product application is done once a day for 10 days. The hairy heel wart is visually evaluated on a five part scale that includes: lesion size, description, pain, color, and swelling. Evaluation of the lesion is conducted daily to follow change in appearance of the lesion. Subjective scores are converted to a numerical index in order to develop a "total lesion score." These field trial methods are being used to develop non-antibiotic treatment products for hairy heel warts. Initial results indicate efficacy for an iodine formulation with high free iodine levels.

description: A practical and convenient procedure for the nucleophilic aromatic substitution of aryl fluorides and chlorides with dimethylamine was developed using a hydroxide-assisted thermal decomposition of N,N-dimethylforamide. These conditions are tolerant of nitro, nitrile, aldehyde, ketone, and amide groups but will undergo acyl substitution to form amides for methyl esters and acyl chlorides. Isolated yields of the products range from 44% to 98%, with the majority being greater than 70% for 17 examples.

description: A novel series of some 2-[(9-ethyl-9H-carbazol-3-yl)imino]thiazoles/thiazolidinones was synthesized and established by spectroscopic tools and elemental analysis. The synthetic strategy depended on cyclization of 1-(9-ethyl-9H-carbazol-3-yl)-3-phenylthiourea (2) with different α-halocarbonyl compounds and some carbon electrophiles under mild reaction conditions. All products were screened for their in vitro cytotoxic activities toward three human cancer cell lines (MCF-7, HepG-2 and HCT-116). Interestingly, the particular carbazolyl derivatives 7, 13, 14 and 16 exhibited promising cytotoxicity results against all the evaluated cell lines. Also, molecular docking studies for the highly bioactive compounds were achieved to investigate the binding mode toward (VEGFR-2-KDR) receptor. Moreover, anticancer results were validated computationally by applying SwissADME server.

Publisher: name: American Association of Bovine Practitioners  Proceedings of the Annual Conference

description: Chronic subacute rumen acidosis is a significant concern in the dairy industry. The syndrome results from a variety of causes including insufficient transition time from dry cow to high production diets, too high a level of fermentable feedstuff in the diet (or conversely too low a level of effective fibre) or inadequate feedbunk management which allows boluses of highly fermentable feed to reach the rumen. Nordlund et al have published a detailed review of the etiology and clinical signs.1 Although the disease generally does not cause overt clinical signs, it can have serious implications on herd health and production. Herd level problems attributed to the syndrome include chronic laminitis, poor appetite or cyclical feed intake, poor body condition in spite of adequate energy intake, hemoptysis, unexplained abscesses, intermittent diarrhea, and high herd cull rates for poorly defined health problems.2 The absence of obvious clinical signs makes diagnosis of subacute rumen acidosis difficult. By the time the animal shows symptoms of the syndrome, several weeks may have passed, making diagnostic tests inconclusive or misleading. As a result, in dairy herds at high risk, because of feeding management practices, a subsample of the herd, consisting of cows in transition and cows at peak production should have their rumen pH monitored.

description: Background: Based on previous evidence person-centred care (PCC) as a quality indicator is important in long-term care (LTC) settings for older people. Effective ways to increase nurses' person-centred care competence are missing. Aim: To evaluate the effectiveness of a continuing education (CE) intervention named ‘Person First—Please’ (PFP) for improving nurses' PPC competence and its connection to PPC climate. Methods: Quasi-experimental cluster design with intervention and control groups was carried out in LTC settings for older people. The intervention group (n = 77) received a 10-week CE intervention, with control group (n = 123) working as usual. The primary outcome was professional nurses' PCC competence. Secondary outcome was the PCC climate as perceived by nurses and, residents with their next of kin. Measurements were conducted pre−/post-intervention and after 6 weeks using the validated, Person-centred Care Competence scale and the Person-centred Care Climate questionnaire, staff and patient versions. Data was analysed with descriptive and inferential statistics. Results: PCC competence was significantly increased in the intervention group and remained after 6 weeks of follow-up. PCC climate increased in the intervention group in total score and also in all sub-scales, across residents with their next of kin. The control group did not show any significant change. Comparisons of PCC competence and PCC climate in time between intervention and control groups confirmed that changes seen between groups were statistically significant in intervention group. Limitations: Measurements were self-assessments, which may have been affected by bias, especially in context of competence assessment. Conclusion: The intervention was effective in increasing professional nurses' PCC competence and on person-centred care climate in long-term care settings for older people.

description: Hypocalcemic relapses affect about 25 to 40% of all dairy cows that are successfully treated for clinical milk fever. Oral calcium supplements may have benefit in reducing the incidence of hypocalcemic relapses, but have not been evaluated for this purpose. Seventy spontaneous cases of milk fever in Holstein cows were used in a prospective, double-blind field study to evaluate the efficacy of an oral calcium gel (Balance TM, Bayer Animal Health, Shawnee Mission, KS) in preventing hypocalcemic relapses.

description: As part of the process of developing criteria by which to accurately interpret milk urea nitrogen (MUN) measurements and correctly use this information in the nutritional management of dairy herds, it is important to understand how certain factors related to sample collection, sample type and sample handling may effect these measurements. Research by Gustaffson and Palmquist (J. Dairy Sci. 76:4 75-484) and by Carlsson and Bergstrom (Acta Vet. Scand. 35:67-77) has demonstrated that there may be considerable diurnal variation in MUN levels, with peak MUN levels being reached 3 to 5 hours post-feeding. Although feeding schedules were identified as a major factor influencing diurnal variation, it is possible that other factors may be involved. Herd level and cow level factors such as the rations fed, feeding frequency, feeding management system, stage of lactation, parity and level of production may each play a part in influencing diurnal variation in MUN levels.

description: A practical and convenient procedure for the nucleophilic aromatic substitution of aryl fluorides and chlorides with dimethylamine was developed using a hydroxide assisted, thermal decomposition of N,N-dimethylforamide. These conditions are tolerant of nitro, nitrile, aldehyde, ketone, and amide groups but will undergo acyl substitution to form amides for methyl esters and acyl chlorides. Isolated yields of the products range from 44 − 98%, with the majority being greater than 70% for seventeen examples.

description: An observational study was conducted in 79 mature Holstein cows from 28 dairy farms selected from Ontario Veterinary College, Ruminant Field Service clients that participated in a monthly herd health program. The objectives were to measure and describe the serum levels of calcium and phosphorus, to evaluate the relationships between these two values in the parturient paresis syndrome of dairy cows and to find specific cut-off values to better predict clinical milk fever cows. All eligible third plus lactation cows entered the study if the calving occurred between February 15 and May 15, 1992. All cows were examined within the first 24 hours after parturition by a farm service clinician. A standard questionnaire and physical examination sheet was completed for every cow. At the end of the evaluation, a serum sample was taken from the caudal vein with a vacutainer vial.

Production of volatile compounds by mixed cultures of Pichia guilliermondii and Saccharomyces cerevisiae

description: During fermentation it was necessary to evaluate the united interactions in the metabolic activity of Saccharomyces cervevisiae x Saccharomyces uvarum (S6u) and Pichia guilliermondii, yeast which was present on the grapes in different proportions at the time of harvest. The results highlight the fact that Pichia guilliermondii strongly influences the fermentation process and the total metabolic result. For this reason, the presence of Pichia guilliermondii which is on the grapes at the time of harvest needs to be evaluated closely due to the fact it is competitive against Saccharomyces and it is important to note a velocity of sugar fermentation which is inferior to Saccharomyces. For optimal regulation of fermentation it is necessary for the technician to detect Pichia guilliermondi presence in musts. The massive presence of Pichia guilliermondii at pressing leads to slowing down or stoppage of fermentation and the production of high concentrations of benzyl alcohol and acetoin; it is therefore important to use healthy grapes at harvest and filtering the must if necessary to reduce the presence of Pichia guilliermondii.

description: Lungworm disease has classically been described in young calves and occasionally yearlings, with rare occurrences of a re-infestation syndrome in adults. The condition, like other nematode-induced disorders, has decreased in incidence among dairy herds with the widespread use of endectocides in replacement stock. However, in the last decade in Eastern Canada, anecdotal reports from practitioners and articles in farming journals give the impression that the incidence of lungworm disease in adult lactating cattle is higher than usual. At the same time, pasture management methods are changing in some of the dairies where grazing of replacement stock and/or lactating cows is still practiced. Bovine practitioners lack information on actual prevalence of the parasite and risk factors that predispose a herd to infection. A randomized cross-sectional survey was conducted to establish the prevalence of herds with Dictyocaulus viviparus (D.v.) infected first-lactation cows in the province of Quebec and to evaluate risk factors associated with herd infection.

description: This study aimed to validate the septic arthritis diagnosis using International Classification of Diseases (ICD)-10 codes against the Newman criteria. Additionally, the study presents disease characteristics and compares subgroups. 475 patients with an ICD-10 code for septic arthritis were identified at a university (n = 265) and a county (n = 167) hospital in West Sweden between 2016 and 2019. Medical records were analysed for adherence to the Newman criteria. Clinical data and culture results were compared between the university hospital and the county hospital, as well as between subgroups categorised by the pathogenetic route of infection, including direct inoculation and haematogenous spread infection. 91% of the patients fulfilled the Newman criteria (52% positive for synovial culture or PCR, 24% positive culture from blood or elsewhere, and 24% with radiological evidence or turbid synovial fluid). The patient population was predominantly male (62%), with a median age of 69 years, and the knee was the most commonly affected joint (39%). Staphylococcus aureus emerged as the predominant pathogen across all patient groups. 80% had a haematogenous spread septic arthritis, while 20% resulted from direct inoculation. In the haematogenous spread groups, patients were older, with fewer males, but higher CRP levels compared to those in the direct inoculation group. ICD-10 codes for septic arthritis have a positive predictive value of 91% in relation to the Newman criteria in Swedish hospital care, making the utilisation of ICD-10 codes a reliable data source for future epidemiological studies.
