Armstrong State University is a four-year public university, part of the University System of Georgia. It is located on a 268-acre campus in suburban Savannah, Georgia, United States. The campus is approximately fifteen minutes from downtown Savannah and 25 miles from Tybee Island beaches. Armstrong offers undergraduate and graduate degrees; it has a student enrollment of approximately 7,600 students, including close to 1,000 graduate students.Armstrong was founded in 1935 by Thomas Gamble, mayor of Savannah, as Armstrong Junior College. The institution expanded into a four-year university in 1964.Fielding athletic teams known as Armstrong Pirates, the university competes at the NCAA Division II level as a member of the Peach Belt Conference. Armstrong's official colors are maroon and gold. Wikipedia.

To assess the rates of therapeutic international normalized ratio (INR) levels between pharmacist-managed clinics compared to traditional physician-management and to determine the variation in rates of therapeutic INR levels between pharmacist-managed clinic data compared to physician-management. Retrospective, randomized, chart review. Referral only, outpatient, pharmacist based anticoagulation clinic under a community based tertiary care health system. Sixty-four patients with at least 1 year's worth of visits to the pharmacist managed clinic were reviewed for INR stability. The average percentage of visits within the defined therapeutic range, was 71.1% for the physician-managed group versus 81.1% for the pharmacist- managed group (P\0.0001). The estimated variance in average therapeutic INR rates was double for the physician-managed group (365.7) versus the pharmacistmanaged group (185.2) (P = 0.004). The pharmacistmanaged anti-coagulation clinic had higher rates of INRs determined to be therapeutic and also exhibited significantly less variability in therapeutic INR rates relative to the physician-managed service. © Springer Science+Business Media, LLC 2011.

The incidence of fungal endocarditis is increasing. While the pathogenic mechanisms are not fully understood, infection is associated with underlying heart disease and is most often attributable to Candida species. Candidal endocarditis complications include heart damage, inflammation, and emboli with resulting ischemia and tissue death. Candidal endocarditis is difficult to diagnose as blood cultures are often negative. Treatment includes surgical intervention and antifungal therapy. This case study describes a 41-year-old female complaining of acute onset of pain with numbness and tingling in both lower extremities. Prior history was significant for mycotic valve aneurysm and replacement secondary to culture-negative endocarditis. Evidence of limb-threatening ischemia led to a bilateral thrombectomy. During the thrombectomy white debris, later identified as Candida albicans, was encountered. A transesophogeal echocardiogram revealed a pedunculated mass which was determined to be the source of infection. The patient was placed on micafungin and voriconazole and discharged with a diagnosis of C. albicans fungal infection with descending aorta fungal mass. This case study illustrates an unusual presentation of candidal endocarditis with discussion of disease epidemiology, pathogenesis, diagnosis, and treatment. Source

Sexual signals in cactophilic Drosophila mojavensis include cuticular hydrocarbons (CHCs), contact pheromones that mediate female discrimination of males during courtship. CHCs, along with male courtship songs, cause premating isolation between diverged populations, and are influenced by genotype × environment interactions caused by different host cacti. CHC profiles of mated and unmated adult flies from a Baja California and a mainland Mexico population of D. mojavensis reared on two host cacti were assayed to test the hypothesis that male CHCs mediate within-population female discrimination of males. In multiple choice courtship trials, mated and unmated males differed in CHC profiles, indicating that females prefer males with particular blends of CHCs. Mated and unmated females significantly differed in CHC profiles as well. Adults in the choice trials had CHC profiles that were significantly different from those in pair-mated adults from no-choice trials revealing an influence of sexual selection. Females preferred different male CHC blends in each population, but the influence of host cactus on CHC variation was significant only in the mainland population indicating population-specific plasticity in CHCs. Different groups of CHCs mediated female choice-based sexual selection in each population suggesting that geographical and ecological divergence has the potential to promote divergence in mate communication systems. © 2012 European Society For Evolutionary Biology.

Transcranial magnetic stimulation (TMS) is a diagnostic and therapeutic modality that is being developed as both an acute and preventive treatment for migraine. TMS delivers a fluctuating magnetic field from the scalp surface to induce current in the subjacent cortex. Magnetic pulses are delivered one at a time in single-pulse TMS (sTMS) or as a train of pulses in repetitive TMS (rTMS). For most of its 30-year history, TMS has been delivered in clinical and research settings using large tabletop devices. Based on the theory that sTMS may disrupt cortical spreading depression, sTMS has been studied and shown to be effective as an acute treatment for migraine with aura. Subsequent work in animal models confirms that sTMS disrupts cortical spreading depression. To make outpatient self-treatment possible, a portable device has been developed for acute treatment of migraine with aura. Based on the theory that rTMS alters brain excitability and neurotransmitter activity, rTMS has been studied as a preventive migraine treatment. A small body of evidence suggests that rTMS may have a role, but further studies are needed. In this review, we summarize the data on TMS as a treatment of migraine, and we suggest directions for future research. © 2010 The American Society for Experimental NeuroTherapeutics, Inc. Source

Objective: To provide updated evidence-based recommendations for the preventive treatment of migraine headache. The clinical question addressed was: What pharmacologic therapies are proven effective for migraine prevention? Methods: The authors analyzed published studies from June 1999 to May 2009 using a structured review process to classify the evidence relative to the efficacy of various medications available in the United States for migraine prevention. Results and Recommendations: The author panel reviewed 284 abstracts, which ultimately yielded 29 Class I or Class II articles that are reviewed herein. Divalproex sodium, sodium valproate, topiramate, metoprolol, propranolol, and timolol are effective for migraine prevention and should be offered to patients with migraine to reduce migraine attack frequency and severity (Level A). Frovatriptan is effective for prevention of menstrual migraine (Level A). Lamotrigine is ineffective for migraine prevention (Level A). Copyright © 2012 by AAN Enterprises, Inc. Source
