Phytoalexins are substances produced by plants that act as potent inhibitors of pathogens. Pterocarpans are biologically active isoflavonoids most commonly found in the family Fabaceae that have the ability to act as phytoalexins. It is made up of a tetracyclic ring system possessing benzofuran-benzopyran. A very great number of pterocarpans have been isolated from natural sources and they are proved to have significant biological activities such as anti-microbial, anti-cancerous, anti-inflammatory and anti-malarial activities. Recently, pterocarpans gained lot of attention because of the broad range of anti-cancer activities in various cancer cell lines such as breast, leukemia, cervical, lung, colon and melanoma. Interestingly, pterocarpans exhibited inhibitory potency against many enzymes such as PTP1B, Neuraminidase, and α-glycosidase. In addition, they were shown to have anti-estrogenic and anti-diabetic activities. This review is a comprehensive inventory of the structures and sources of pterocarpans and it emphasizes on the biological evaluations of pterocarpans from various plant sources and their scope as a lead molecule. © 2017

An analysis of collegiate undergraduate programs by AffordableCollegesOnline.org has determined the best places to earn an Associates and Bachelor’s Degree Online in the nation for 2016-2017. As a leader in online higher education resources, the site measured cost and quality data to determine the top college online undergraduate degree programs. Highest marks were awarded to Goodwin College, Great Basin College, Keiser University Fort Lauderdale, East Mississippi Community College, Western Wyoming Community College and Holmes Community College in the associate degree category; Dickinson State University, Siena Heights University, Fort Hays State University, Davenport University, Judson College and Northern Arizona University in the bachelor’s degree category. "Undergraduate enrollment numbers in the U.S. rose 21 percent between 2003 and 2013. As more students attend college, the need for flexible learning options also grows,” said Dan Schuessler, CEO and Founder of AffordableCollegesOnline.org. "Colleges offering online undergraduate programs are showing their ability to adapt to those needs, and we’ve identified the places students looking for online associate and bachelor’s degree programs can go for an affordable, quality education.” Schools must meet specific criteria to qualify for the Best Online Associate Degree Programs & Best Online Bachelor’s Degree Programs lists. All institutions must be accredited, public or private not-for-profit entities and must offer in-state tuition maximums of $5,000 per year at two-year schools and $25,000 per year at four-year schools. Eligible institutions are further evaluated by a variety of cost and quality measures to determine their position on the lists, including financial aid offerings, graduation rates and online program variety.

In this work, precise Stark effect measurements have been carried out on several transitions in the first four torsional states of methanol. The Stark shifted transition frequencies for a wide range of steady electric field have been measured with an accuracy of approximately ±10 kHz. Detailed analysis of the data allowed for the determination of the dipole moment components in the first four torsional states of the ground vibrational state. The extrapolated zero field frequencies of the transitions studied have been determined and found to be in perfect agreement with known values. For the torsional ground state the values of μa = 0.8961(2) and μb = 1.4201(9) have been obtained, whereas for the first excited torsional state the corresponding values obtained are 0.9035(1) and 1.4317(5) (These values are in Debye, denoted by D). These values confirm the fact that the dipole moment values increase at a considerable rate as one move toward higher torsional states as seen in previous studies. To our knowledge, this is the first time the most accurate and elaborate dipole moment values of methanol are being reported. © 2015 Elsevier Inc. All rights reserved.

In this work, Stark effect measurements have been carried out on several transitions C-13 substituted species of triply-deuterated (D3) methanol. The analysis of the data allowed the determination of the dipole moment components in the first two torsional states of the ground vibrational state of this species. The extrapolated zero field frequencies of the transitions studied have been determined and found to be in excellent agreement with known values. For the torsional ground state the values {in Debye (D)} of μa = 0.9080(9) and μb = 1.4378(10) have been obtained for this species. These values increase for the first excited state as was observed for other species. The dipole moment values are considerably higher than the non-deuterated species. To our knowledge the present study represents the measurement of the most accurate dipole moment values of 13CD3OH for the first time. The results obtained will prove useful for radio astronomy and in understanding of large amplitude internal energy pathways in polyatomic molecules. © 2015 Elsevier B.V. All rights reserved.

AIDS Patient Care and STDs | Year: 2015

The challenges that face African American women living with HIV are immense. African American women continue to be disproportionately infected and affected by this chronic and life-threatening infection in a complex context of individual experience, interactions with the environment, formal and informal support systems, and cultural belief systems. This article identifies the Theory of Silencing the Self (STS) and a widely known model, the Social Ecological Model (SEM), as a synthesized explanatory framework in helping nurses understand how to address research questions and clinical care that is congruent with the experience of African American women living with HIV infection. In synthesizing the components of these two frameworks, an explanation of the relationship between disempowerment and depression in this population will be uncovered as a key component to making relationships at the individual, family, and community level better. Helping African American women living with HIV infection to explore and address how choosing to be silent across their life systems will advance healthcare adherence as we currently know it to improved self-management of a chronic, gender-specific, culturally-bound experience of depression. © 2015 Mary Ann Liebert, Inc.
