Infection by endosymbiotic bacteria is an underappreciated threat to endangered arthropods with serious implications for captive management programs. We examined the nature of Wolbachia infection in the North American endangered Karner blue butterfly, Lycaeides melissa samuelis, as a case study. Screening for Wolbachia across the range of the species confirmed widespread infection in the wester...

Synergistic antibacterial interaction between Melissa officinalis extracts and antibioticsOlgica Stefanovic, Ljiljana Comic

BACKGROUND Melissa officinalis, an herbal drug, is well known and frequently applied in traditional and modern medicine. Yet, there is inadequate information regarding its effects on electrical properties of the heart. The present study attempted to elucidate the effects of Melissa officinalis aqueous extract on electrocardiogram (ECG) in rat. OBJECTIVES ECG is an easy, fast and valuable tool...

We prove Iqbal’s conjecture on the relationship between the free energy of closed string theory in local toric geometry and the Wess-ZuminoWitten model. This is achieved by first reformulating the calculations of the free energy by localization techniques in terms of suitable Feynman rule, then exploiting a realization of the Feynman rule by free bosons. We also use a formula of Hodge integrals...

Melissa M. Amick, PhD  the number of drivers over the age of 75 will dramatically increase over the next few decades. Adults age 85 and older have the highest rate of driver fatalities. Individuals age 70 and older have the greatest motor vehicle fatality rates per mile driven compared to all but the riskiest age group, those 25 years and younger. Advanced age is also a risk factor for motor v...

In no area of the social sciences has ideology contaminated knowledge more pervasively than in writings on the sex industry. Too often in this area, the canons of scientific inquiry are suspended and research deliberately skewed to serve a particular political agenda. Much of this work has been done by writers who regard the sex industry as a despicable institution and who are active in campaig...
