Parkinson’s Disease—Apoptosis and Dopamine Oxidation  [PDF]
James David Adams Jr.
Open Journal of Apoptosis (OJApo) , 2012, DOI: 10.4236/ojapo.2012.11001
Abstract: Tyrosine hydroxylase, monoamine oxidase and aldehyde dehydrogenase all form oxygen radicals as part of their mechanisms of action. These oxygen radicals damage dopaminergic neurons in the substantianigra of the midbrain and cause them to die by a process of necrosis or apoptosis. Oxygen radicals quickly abstract hydrogen from DNA forming DNA radicals and causing DNA fragmentation, activation of DNA protective mechanisms, NAD depletion and cell death. Tyrosine hydroxylase is present in all dopaminergic neurons, is involved in the synthesis of dopamine and forms oxygen radicals in a redox mechanism involving its cofactor, tetrahydrobiopterin. Levodopa is used therapeutically in Parkinson’s disease patients since it is a precursor for dopamine, an inhibitor of tyrosine hydroxylase, and prolongs pa-tient’s lives. Monoamine oxidase converts dopamine into 3,4-dihydroxyphenylacetaldehyde and forms oxygen radi-cals.Aldehyde dehydrogenase oxidizes the aldehyde and forms oxygen radicals and 3,4-dihydroxyphenylacetic acid. The treatment of Parkinson’s disease should involveinhibitors of oxygen radical formation in dopaminergic neurons and neuroprotective agents that stimulate DNA repair and prevent cell death.

Immiserizing Credit: Challenging the Efficacy of Microfinance  [PDF]
Frank Raymond, John Adams
Modern Economy (ME) , 2013, DOI: 10.4236/me.2013.48058

Despite a dearth of theoretical studies, there is widespread perception that microfinance is an enormously useful tool for economic development. However, an increasing number of households in lesser developed countries are facing the same debt squeeze as those in the developed world, but are less able to manage debt responsibilities. The consequences are much more dramatic for LDC households because a much larger portion of household income is necessary for subsistence. As such, microfinance can become immiserizing for poor families with few assets. We develop a dynamic model that allows households to use credit markets in order to augment household consumption or capital. Results indicate a proclivity for households to increase debt over time, challenging the efficacy of microfinance as a sustainable tool for development.

Doorstop: Text-Based Requirements Management Using Version Control  [PDF]
Jace Browning, Robert Adams
Journal of Software Engineering and Applications (JSEA) , 2014, DOI: 10.4236/jsea.2014.73020

Effectively managing the requirements and traceability in a complex software project can be a challenging task. Many tools exist to support the initial creation and management of changes to text-based requirements. The most popular commercial solutions use a centralized server to host a database with a front-end desktop or web interface. Some downsides to this approach include user interface bloat, server costs, and an inherent disconnection from the project’s source files. To provide an alternative to traditional requirements management, Doorstop was created as a tool to allow requirements to be stored as text files in version control. This solution allows a project to utilize its existing development tools to manage versions of the requirements using a lightweight, developer-friendly interface.

Varicose Veins, Retinal Tears and Deep Vein Thrombosis, New Insights into the Causes from Adams Disease  [PDF]
James David Adams Jr.
Open Journal of Apoptosis (OJApo) , 2015, DOI: 10.4236/ojapo.2015.43006
Abstract: Adams disease is the consequence of overly active transient receptor potential cation channels (TRP). This case report presents a patient suffering from multiple vascular problems and may provide new insights into the causes of venous problems. Endothelial and smooth muscle cells in veins contain TRP. These channels when activated excessively result in calcium accumulation, oxygen radical formation and apoptosis of endothelial and smooth muscle cells. The death of critical cells in vein valves, may lead to varicose veins. The loss of endothelial cells in venules may lead to retinal tears. Damage to vein walls may lead to a deep vein thrombosis. Transient receptor potential cation channels may be new drug targets of interest in the treatment or prevention of these conditions.

Azubuike Adams, Azubuike Amarachi Salome
Open Journal of Ecology (OJE) , 2014, DOI: 10.4236/oje.2014.410051

In the course of this work which is the impact of zoological garden in schools, the questionnaire interviewed was used in the collection of data. Based on the finding it was observed that people visit zoological gardens for different purposes like educational, recreational, research, economic and cultural values. Also the chi-square (X2) is used in this research to show if there is significant difference or not. Result indicated that people from various works of life visited the zoo. Some recommendations were also made for further studies as well as the opposition of establishment of a zoo. Thus, the objectives of the this work are to identify the conservation areas in which zoos make a contribution, to develop understanding and support of the conservation potentials of zoos, to convince local zoos and conservation agencies that they can make important contributions to conservation, to help zoos formulate conservation priorities and policies and finally, to promote action of individual zoos by participation in the global zoo and other conservation network.

Prospective Development of Small Molecule Targets to Oncogenic Ras Proteins  [PDF]
Reena Chandrashekar, Paul D. Adams
Open Journal of Biophysics (OJBIPHY) , 2013, DOI: 10.4236/ojbiphy.2013.34025

Abnormal expression or mutations in Ras proteins has been found in up to 30% of cancer cell types, making them excellent protein models to probe structure-function relationships of cell-signaling processes that mediate cell transformtion. Yet, there has been very little development of therapies to help tackle Ras-related diseased states. The development of small molecules to target Ras proteins to potentially inhibit abnormal Ras-stimulated cell signaling has been conceptualized and some progress has been made over the last 16 or so years. Here, we briefly review studies characterizing Ras protein-small molecule interactions to show the importance and potential that these small molecules may have for Ras-related drug discovery. We summarize recent results, highlighting small molecules that can be directly targeted to Ras using Structure-Based Drug Design (SBDD) and Fragment-Based Lead Discovery (FBLD) methods. The inactivation of Ras oncogenic signaling in vitro by small molecules is currently an attractive hurdle to try to and leap over in order to attack the oncogenic state. In this regard, important features of previously characterized properties of small molecule Ras targets, as well as a current understanding of conformational and dynamics changes seen for Ras-related mutants, relative to wild type, must be taken into account as newer small molecule design strategies towards Ras are developed.
