Turkish Journal of Zoology

The aim of this study is to review the brachypterous species within the genus Alloxysta Förster, 1869. The known brachypterous species of Alloxysta have been compared with fully winged species in order to establish hypotheses regarding dimorphism for wing length and shape. This analysis is based only on the morphological features shared between species; breeding and genetic analyses will be necessary to test and refine these hypotheses. Two new brachypterous species are described here: Alloxysta curta Ferrer-Suay sp. nov. and Alloxysta pseudoconsobrina Ferrer-Suay sp. nov. Six species are revised. In total, there are now 8 brachypterous species known in this …


Heterochromatin Distribution And Localization Of Nors In The 2n = 48cytotypes Of Nannospalax Xanthodon And N. Ehrenbergi, Ati̇lla Arslan, Jan Zima Jan 2017

Heterochromatin Distribution And Localization Of Nors In The 2n = 48cytotypes Of Nannospalax Xanthodon And N. Ehrenbergi, Ati̇lla Arslan, Jan Zima

Turkish Journal of Zoology

We compared the C-banding pattern and the NOR distribution in 3 populations of N. xanthodon and N. ehrenbergi with 48 chromosomes from Turkey, with the aim to reveal variations between and within species. We have found distinct variation in the C-banding and the NOR distribution pattern among the 3 populations compared; each of them possessed its own specific chromosomal features. However, it is not possible to distinguish between intra- and interspecific variation, and the observed patterns cannot be utilized for unequivocal species recognition.

The Progression Of Lyme Disease In The State Of Virginia, Margaret Michel Jan 2017

The Progression Of Lyme Disease In The State Of Virginia, Margaret Michel

Honors Theses

Lyme disease has spread in the United States from the northeast to more southern and western parts of the country. It has been shown that the tick which most often carries the Lyme disease pathogen (Borrelia burgdorferi) in North America, Ixodes scapularis, has also spread to these new areas of concern. In Virginia, the disease has progressed from the eastern shore to the western, more mountainous regions. Through obtaining historical museum specimens of mice from 11 locations in Virginia, we seek to determine whether the Lyme disease causing pathogen, B. burgdorferi, has always been present in …

Joshi

Bioelectrics Publications

Bacillus anthracis secretes three secretary proteins; lethal factor (LF), protective antigen (PA) and edema factor (EF). The LF has ability to check proliferation of mammary tumors, chiefly depending on mitogen activated protein kinase (MAPK) signaling pathway. Evaluation of therapeutic potential of recombinant LF (rLF), recombinant PA (rPA) and lethal toxin (rLF + rPA = LeTx) on the primary mammary ductal carcinoma cells revealed significant (p < 0.01) reduction in proliferation of tumor cells with mean inhibition indices of 28.0 ±1.37% and 19.6 ± 1.47% respectively. However, treatment with rPA alone had no significant anti-proliferative effect as evident by low mean inhibition index of 3.4 ± 3.87%. The higher inhibition index observed for rLF alone as compared to LeTx is contrary to the existing knowledge on LF, which explains the requirement of PA dependent endocytosis for its enzymatic activity. Therefore, the plausible existence of PA independent mode of action of LF including direct receptor mediated endocytosis or modulation of signal transduction cascade via unknown means is hypothesized. In silico protein docking analysis of other cellular receptors for any plausibility to play the role of receptor for LF revealed c-Met receptor showing strongest affinity for LF (H bond = 19; Free energy = …

All Peer-Reviewed Publications

Global change is resetting the spatial and ecological equilibrium of complex co-evolutionary relationships between plants and their insect herbivores. We review the mechanisms at play in the responses of plant–insect interactions to global changes, including increased temperature and atmospheric CO2 concentrations, modification of land use and pollution. We distinguish between the direct effects of global changes on each partner from the indirect impacts on insects via the responses of plants. The indirect effects include a change in the nutritional quality of the plant tissues for herbivore insects, as well as a change in the microclimatic conditions at the leaf surface. …

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins Jan 2017

From Disposable Culture To Disposable People: Teaching About The Unintended Consequences Of Plastics, Sasha Adkins

Antioch University Dissertations & Theses

Plastics, the epitome of disposable culture, pose both a toxicological and a spiritual problem. This dissertation examines plastics at a molecular level using the discourse of endocrine disruption, and at a sociological level using the discourses of eco-theology and environmental justice. Adding to the literature on the adsorption of toxicants to plastic marine debris, I demonstrate that certain types of plastic -- those containing mercaptans, such as styrene butadiene block copolymer -- efficiently concentrate methyl mercury from seawater. Further, samples of polycarbonate contributed mercury to seawater. I propose the term plastic-mediated magnification to describe the phenomenon that plastics, along with …
