The strain Saccharomyces cerevisiae Y500-4L, previously selected from the must of alcohol producing plants and showing high fermentative and killer capacities, was characterized according to the interactions between the yeasts and examined for curing and detection of dsRNA plasmids, which code for the killer character. The killer yeast S. cerevisiae Y500-4L showed considerable killer activity against the Fleischmann and Itaiquara commercial brands of yeast and also against the standard killer yeasts K2 (S. diastaticus NCYC 713), K4 (Candida glabrata NCYC 388) and K11 (Torulopsis glabrata ATCC 15126). However S. cerevisiae Y500-4L showed sensitivity to the killer toxin produced by the standard killer yeasts K8 (Hansenula anomala NCYC 435), K9 (Hansenula mrakii NCYC 500), K10 (Kluyveromyces drosophilarum NCYC 575) and K11 (Torulopsis glabrata ATCC 15126). No M-dsRNA plasmid was detected in the S. cerevisiae Y500-4L strain and these results suggest that the genetic basis for toxin production is encoded by chromosomal DNA. The strain S. cerevisiae Y500-4L was more resistant to the loss of the phenotype killer with cycloheximide and incubation at elevated temperatures (40oC) than the standard killer yeast S. cerevisiae K1.

Owing to improvements in its mechanical properties and to the availability of shade and translucence resources, resin composite has become one of the most widely used restorative materials in present day Dentistry. The aim of this study was to assess the relation between the surface hardness of seven different commercial brands of resin composites (Charisma, Fill Magic, Master Fill, Natural Look, Opallis, Tetric Ceram, and Z250) and the different degrees of translucence (translucid, enamel and dentin). Vickers microhardness testing revealed significant differences among the groups. Z250 was the commercial brand that showed the best performance in the hardness test. When comparing the three groups assessed within the same brand, only Master Fill and Fill Magic presented statistically significant differences among all of the different translucencies. Natural Look was the only one that showed no significant difference among any of the three groups. Charisma, Opallis, Tetric Ceram and Z250 showed significant differences among some of the tested groups. Based on the results found in this study, it was not possible to establish a relation between translucence and the microhardness of the resin composites assessed. Depending on the material assessed...

INTRODUCTION : With the interest in anticipating access to the result of intraoral radiography, the radiographic processing is frequently neglected, compromising image quality. OBJECTIVE : The aim of this study was to evaluate the influence of interrupting the fixation process on the radiographic contrast and base-plus-fog density (BPFD) in three brands of periapical films. MATERIAL AND METHOD : Ninety radiographs were taken of an aluminum stepwedge and a lead plate for each brand, and they were divided according to the time of initial immersion in the fixative in: control group (without interrupting the fixing), 5, 10, 20, 30 and 40 seconds. During processing, films had the fixing stage stopped and were exposed to a negatoscope for 1 minute, then the fixation time of 10 minutes was completed. The radiographs were digitized and exported to Image Tool 3.0.software. RESULT : Kodak(r) film showed no statistically significant differences between groups, while Agfa(r) film presented difference in BPFD compared with Group 5 seconds, and Dentix(r) film showed statistical difference in all groups in comparison with the control group. CONCLUSION : Under the conditions studied, Kodak(r) film is not influenced by disruption of fixation as regards BPFD and image contrast...

Nine different brands of membrane filter were compared in the membrane filtration (MF) method, and those with the highest yields were compared against the most-probable-number (MPN) multiple-tube method for total coliform enumeration in simulated sewage-contaminated tap water. The water was chlorinated for 30 min to subject the organisms to stresses similar to those encountered during treatment and distribution of drinking water. Significant differences were observed among membranes in four of the six experiments, with two- to four-times-higher recoveries between the membranes at each extreme of recovery. When results from the membranes with the highest total coliform recovery rate were compared with the MPN results, the MF results were found significantly higher in one experiment and equivalent to the MPN results in the other five experiments. A comparison was made of the species enumerated by these methods; in general the two methods enumerated a similar spectrum of organisms, with some indication that the MF method was subject to greater interference by Aeromonas.

Little is known about the incidence of injury to race track motor-cyclists and car drivers. In a 1-year study at Brands Hatch, 70 of 33,184 competitors required hospital treatment. We found this injury rate to be higher than on the public highway. However, the anatomical distribution of injury caused by motor-bike accidents is similar to that found on the public highway. Motor-cyclists are more likely than car drivers to sustain limb trauma requiring outpatient treatment only. The number of participants requiring admission to hospital is broadly similar for car and bike races, being less than 0.1%.

Two lots of brand-name and three lots of non-proprietary tolbutamide products, the latter having been reported to be clinically ineffective, were compared in a double-blind study in 22 diabetic patients. Every patient took each of the five brands for two weeks. The dose range was 1 to 2 g. per day and the dose was kept constant in each patient throughout the five test periods. Statistical analyses of fasting, mid-morning and mid-afternoon blood sugar levels, mid-morning and mid-afternoon blood tolbutamide levels and levels of tolbutamide and its metabolite in 24-hour urine did not show any significant differences among the five products except for better control of fasting blood-sugar levels by one brand, nor did clinical observations reveal any differences.

The relative biological availability (bioavailability) of three brands of ampicillin trihydrate capsules marketed in Canada was studied by means of a crossover experimental design and was evaluated by analysis of variance. After administration of a single oral dose (500 mg.) to volunteer subjects, the mean peak ampicillin serum concentration and the area under the time ampicillin serum concentration curve (AUC) were higher for one of the products than for the other two. A second study utilizing the same experimental design revealed no differences in these parameters when different production lots of the more available product were compared. Product bioavailability was not related to the in vitro dissolution time of the capsules. The experimental design and methods of statistical analysis are discussed.

This article presents selected findings from a qualitative study of Ecstasy sellers and their sales practices, knowledge of distribution networks, buyer-seller relationships, and self-reported drug use. In-depth interviews were conducted with 80 men and women who had sold five or more hits of Ecstasy five or more times in the six months prior to the interview. Study participants described their perceptions of the various types of Ecstasy they had distributed or used themselves. The participants had experience with a variety of Ecstasy labels, from the popular “Blue Dolphin” tablets to the powdered form called “Molly.” We tracked pill brand mentions on Ecstasy-related websites to compare with interviewees’ descriptions of Ecstasy brands. This study examines Ecstasy sellers’ ideas about the role of brand names in Ecstasy markets and their relationship to their beliefs about different types of Ecstasy’s purity and quality. We demonstrate that considering Ecstasy branding increases our understanding of buyer and seller relationships.

Arista is a classical Ayurvedic preparation that is typically used as a digestive and cardiotonic. The present Investigation evaluated five different brands of Dasamoolaristam available in the market as per WHO and Indian Pharmacopoeial specifications. Various physicochemical parameters such as alcohol-soluble extractive, water-soluble extractive, total ash, acid-insoluble ash, total solid, and alcohol content were determined. The present investigation reveals that all the preparations contain acceptable levels of alcohol (less than 12% v/v). However, the preparations were found to contain unacceptable limits of microbial load although all showed the absence of Escherichia coli, Salmonella species, and Staphylococcus aureus.

This study was undertaken to assess the in vitro dissolution and in vivo bioavailability of six brands of ciprofloxacin oral tablets available in the UAE market using rabbits. The in vitro dissolution profiles of the six ciprofloxacin products were determined using the USP dissolution paddle method. Pharmacokinetic modeling using compartmental and noncompartmental analysis was done to determine the pharmacokinetic parameters of ciprofloxacin after single-dose oral administration. In vitro release study revealed that the amount of ciprofloxacin released in 20 minutes was not less than 80% of the labeled amount which is in accordance with the pharmacopoeial requirements. All tested products are considered to be very rapid dissolving except for formulae A and D. Ciprofloxacin plasma concentration in rabbits was best fitted to a two-compartment open model. The lowest bioavailability was determined to be for product A (93.24%) while the highest bioavailability was determined to be for product E (108.01%). Postmarketing surveillance is very crucial to ensure product quality and eliminating substandard products to be distributed and, consequently, ensure better patient clinical outcome. The tested ciprofloxacin generic products distributed in the UAE market were proven to be of good quality and could be used interchangeably with the branded ciprofloxacin product.

In The paradoxical happiness , Gilles Lipovetsky elects five major paradigmatic models that command the pleasure and happiness in our societies. Starting with the paradigmatic models of penia (where it is emphasized the existential dissatisfaction supplied by the consumption and where advertising has a special place, bombarding consumers and creating consumer needs, in addition to selling a lifestyle rather than the products themselves), and narcissus (model constructed on the basis of self-exaltation and abdication of the social and political) intends to examine the relationship between the consumption exercised by young people and the advertising displayed on social networking sites, focusing on the social media Facebook, observing the virtual fan pages of the following brands: Coca-Cola; Pepsi; BlackBerry, Nokia, Riachuelo and C&A and their relationships with their consumers; Coordenação de Aperfeiçoamento de Pessoal de Nível Superior; Em A felicidade paradoxal , Gilles Lipovetsky elege cinco grandes modelos paradigmáticos que comandam a inteligibilidade do prazer e da felicidade em nossas sociedades.

In a spectacle society, in which its forms of advertising communication have lost strength and demonstrated inefficiency, Branded Entertainment appears as an alternative to create emotional links between costumers and brands. Using the entertainment to take their messages, the organizations develop relationships more intense by integrating themselves to the life of those who trust in their positioning and proposals. This essay has the intention of showing the advertising´s actual scenario, making clear what is Branded Entertainment, its use, the environment where it is inserted and consequences for those who had decided to use this kind of strategy. With a case study of the movie Transformers, which protagonist is a vehicle of the brand Chevrolet, it will be showed the theoretical questions used, making a panorama of world´s advertising juncture.; Em uma sociedade do espetáculo, cujas formas de comunicação publicitária tradicionais têm perdido força e pecado por ineficiência, o Branded Entertainment surge como uma alternativa para criar vínculos emocionais entre clientes e marcas.

Using the Loyalty Triangle framework developed by Lewis and Shoemaker (1999) and focus group methodology, the study examined how a niche brand restaurant best achieved long-term loyalty. Results indicate that customers are loyal to a niche brand because of the unique characteristics inherent to the brand. Customers have higher perceptions of such qualities as the presentation of service, consistency of product, and the benefits offered by the loyalty program than characteristics that are shared across all brands. Niche brand restaurants can be more effective in developing these qualities to promote customer loyalty.

This study uses a combination of both qualitative and quantitative approaches to explore the associations that consumers tie to a specific human brand (Jerry Seinfeld) prior to his anticipated co-branding partnership with a regional Australian financial institution. Results of the study identified strong and unique attribute and attitude associations in consumers’ knowledge networks linked to the Jerry Seinfeld brand. These findings have implications for the co-branding partner in terms of the development of strategic positioning focusing on the partners positive salient human brand associations. Interestingly, benefit associations were not identified in this study, suggesting that other methods may be more appropriate in eliciting consumer brand associations for human brands.; http://anzmac2010.org/; Jasmina Ilicic and Cynthia M.
