Drug Therapy Problems in NCAA Division I-A Minnesota Gopher Student-Athletes

As with all competitive sports, in NCAA Division I-A athletics it is important to maximize controllable factors in order for each athlete to compete at his or her best. One important and controllable factor that has the potential for improvement is the athlete’s medication experience. When medications are used to treat the correct condition, administered at the right time, and with the correct dose, they have the potential to improve outcomes and enhance athletic performance. As an example, it is essential that a soccer player who has asthma is using the correct inhaler, at the correct time, with proper technique, and with the correct number of puffs in order to support breathing and improve oxygen transportation during a game. Ineffective and unsafe use of medications can lead to serious disease-related events and also prevent an athlete from achieving their performance goals when they are not being used correctly. The goal of this project was to explore the presence and extent of drug therapy problems (DTPs) among a college athlete population. Within the 10 student-athletes who were interviewed, there were a total of 36 drug therapy problems identified, many of which were tied to a lack of understanding for their own medication regimen. This project suggests that medication-related needs may not be appropriately addressed among the college athlete population. The addition of a pharmacist on the athletic healthcare team would ensure appropriate medication use and optimization for health outcomes and overall athletic performance.   Article Type: Original Researc

EXD2 governs germ stem cell homeostasis and lifespan by promoting mitoribosome integrity and translation

Mitochondria are subcellular organelles critical for meeting the bioenergetic and biosynthetic needs of the cell. Mitochondrial function relies on genes and RNA species encoded both in the nucleus and mitochondria, as well as their coordinated translation, import and respiratory complex assembly. Here we describe the characterization of exonuclease domain like 2 (EXD2), a nuclear encoded gene that we show is targeted to the mitochondria and prevents the aberrant association of mRNAs with the mitochondrial ribosome. The loss of EXD2 resulted in defective mitochondrial translation, impaired respiration, reduced ATP production, increased reactive oxygen species and widespread metabolic abnormalities. Depletion of EXD2/CG6744 in D.melanogaster caused developmental delays and premature female germline stem cell attrition, reduced fecundity and a dramatic extension of lifespan that could be reversed with an anti-oxidant diet. Our results define a conserved role for EXD2 in mitochondrial translation that influences development and aging

Modeling how soluble microbial products (SMP) support heterotrophic bacteria in autotroph-based biofilms

International audienceMulti-species biofilm modeling has been used for many years to understand the interactions between species in different biofilm systems, but the complex symbiotic relationship between species is sometimes overlooked, because models do not always include all relevant species and components. In this paper, we develop and use a mathematical model to describe a model biofilm system that includes autotrophic and heterotrophic bacteria and the key products produced by the bacteria. The model combines the methods of earlier multi-species models with a multi-component biofilm model in order to explore the interaction between species via exchange of soluble microbial products (SMP). We show that multiple parameter sets are able to describe the findings of experimental studies, and that heterotrophs growing on autotrophically produced SMP may pursue either r- or K-strategies to sustain themselves when SMP is their only substrate. We also show that heterotrophs can colonize some distance from the autotrophs and still be sustained by autotrophically produced SMP. This work defines the feasible range of parameters for utilization of SMP by heterotrophs and the nature of the interactions between autotrophs and heterotrophs in multi-species, multi-component biofilms
