Concentration of white blood cells from whole blood by dual centrifugo-pneumatic siphoning with density gradient medium
Due to the pervasiveness of HIV infections in developing countries there exists a need for a low-cost, user-friendly point-of-care device which can be used to monitor the concentration of T-lymphocytes in the patientâs blood expressing the CD4+ epitope. As a first step towards developing a microfluidic âlab-on-a-discâ platform with this aim we present the concentration of white blood cells from whole blood using a density medium in conjunction with centrifugo-pneumatic siphon valves [1]. Two such valves are actuated simultaneously, removing the bulk of plasma through the upper valve and the bulk of WBCs through the lower valve while leaving the vast majority of red blood cells in the centrifugal chamber
Integrating brand, retailer and end-customer perspectives
With increased retailer concentration, competition and the emphasis on private labels, it is easy to assume that manufacturers' brands are less important to retailers. Retailers manage their stores as brands and control the brand offering inside the store, coordinating the manufacturer's brand with the private label. However, manufacturers' brands are still important in determining retailer profitability and store image. This research paper seeks to clarify the value of manufacturers' brands to retailers within marketing channel relationships
Increasing Parity is Associated with Cumulative Effects on Memory
BACKGROUND: The purpose of this investigation was to determine if reproductive experience is associated with cumulative effects on human memory performance during pregnancy and if these effects persist into the postpartum period.
METHODS: Verbal recall memory performance was assessed in 254 women four times during pregnancy and at 3 months postpartum. The relation between parity and memory function was evaluated with hierarchical linear modeling and analysis of covariance (ANCOVA).
RESULTS: The data indicate that the previously documented adverse effects of pregnancy on memory performance are compounded with successive pregnancies. During gestation and postpartum, multiparity was associated with poorer memory function, and these effects did not appear to be due to differences in maternal demographics, depressive symptoms, or sleep quality.
CONCLUSIONS: Animal models demonstrate that the effects of reproduction on brain structure and function are both cumulative and enduring. However, little is known about the influence of reproductive experience on the human female brain. These findings provide evidence that in humans, reproduction is associated with striking and perhaps persisting changes in cognitive function
Evaluating The Impact of Esport Brand Extensions on Brand Equity and Behavioral Intentions
Esport, which consists of video game competitions that fans can watch remotely or attend, is a rapidly growing industry. Although there is trepidation among traditional sport organizations about embracing esport, the popularity of esport with young consumers makes it attractive to sport practitioners. Some traditional sport entities have started to embrace esport. Specifically, the National Basketball Association (NBA) has made a concerted effort to incorporate esport into its brand. Certain NBA franchises (e.g., the Philadelphia 76ers) manage esport teams (e.g., 76ers GC) that compete in the NBA 2K League. The NBA esport teams consist of athletes/gamers who play NBA2K, a sport video game, and compete against other teams in the NBA 2K League. The NBA esport teams therefore act as brand extensions of each NBA franchise (the parent brand). Brand extensions are a common brand management strategy in sport; however, esport brand extensions of a traditional sport parent brand have yet to be studied. The purpose of this research was to test a brand extension model to examine (1) factors that may determine consumersâ esport brand extension evaluations, (2) the relationship between evaluations and extension brand equity, and (3) the impact of identification on extension brand equity. As esport is likely to continue to grow in size and popularity, there is a practical need for sport practitioners to understand esport as a brand extension strategy to attract esport fans and consumers to the parent brand. Furthermore, despite an abundance of brand extension research there are inconsistencies in the theoretical explanations and dimensions that determine how consumers evaluate brand extensions. To assess the practicality of an esport brand extension strategy in traditional sport, and to assess differing theoretical explanations of the factors that influence consumer evaluations of brand extensions, this study examined how potential consumers responded to an esport brand extension of an individual NBA franchise that joined the NBA 2K League in 2019. Surveys were electronically distributed to potential respondents who are representative of the parent brandâs target market and of the overall esport market. A conceptual model was tested using structural equation modeling (SEM) to determine the relationships between these factors
Survival
I was inspired to write this piece while on my Obstetrics rotation. The first time I felt an umbilical cord pulsing from the placenta to the fetus, I was mesmerized. Tears sprung into the corners of my eyes as I held onto this life that was being passed between mother and daughter. The placenta looked like a homogenous jello, warm and deep red. The umbilical cord split into different directions to root itself into it, taking life and giving back to refresh itself anew. The placenta itself was multifaceted, having hundreds of different lobules all working at optimal speed to produce and provide nutrients to baby. It\u27s hard to fathom that such a small structure can grow to house a fetus and everything that comes along with it. I will forever stand in awe at the majesty that is human creation
