Leaf Morphology And Anatomy Of 7 Varieties Of Ficus Deltoidea (Moraceae), Hasan Nudin Nur Fatihah, Mat Nashriyah, Abdul Rashid Nor Zaimah, Mahmud Khairil, Abdul Manaf Ali

Turkish Journal of Botany

The extreme morphological variations and unclear boundaries between varieties can lead to the misleading identification of Ficus deltoidea Jack (Moraceae) varieties. This has encouraged many taxonomists and botanists to study the variation within F. deltoidea. Thus, correct identification of F. deltoidea varieties is important, as several morphological and anatomical characters are variety-specific. The present study aims to evaluate the morphology and anatomy of leaf in 7 varieties of F. deltoidea, namely var. deltoidea, var. angustifolia, var. trengganuensis, var. bilobata, var. intermedia, var. kunstleri, and var. motleyana. It also aims to contribute to the identification of the varieties based on the …

A New Natural Hybrid Between Prosthechea Cochleata And P. Radiata (Orchidaceae) From Alta Verapaz, Guatemala, Edgar Mó, William Cetzal Ix, Germán Carnevali, Eduardo Pérez-García, Saikat Basu

Turkish Journal of Botany

A new natural hybrid between Prosthechea cochleata and P. radiata (Orchidaceae, Laeliinae) from the central part of Guatemala, P. × chixoyensis Mó & Cetzal, is herein described, illustrated, and characterized based on the morphological characters. The new nothospecies is most similar to P. cochleata but the petals are proportionally broader and the mucro of the labellum is subapical, as observed in P. radiata. Additionally, the perianth segments are neither as strongly reflexed as they are in P. cochleata nor patent as in P. radiata. A table of diagnostic characters for the new hybrid and its putative parents, a comparative figure, …

The studied tree specimens were separated in 3 distinct clusters by UPGMA clustering and principal coordinate analysis and multidimensional …

Comparative Analysis Of Hexaploid Avena Species Using Remap And Issr Methods, Edyta Paczos Grzeda, Piotr Tomasz Bednarek

Turkish Journal of Botany

Taxonomic relationships in Avena genus are not evident. Avena sativa L. might have originated either from Avena sterilis L. or Avena fatua L. Alternatively, it may have evolved independently during formation of the hexaploid form. A. fatua may have a different A genome than the other hexaploids. Studies performed with Ty1-copia retrotransposon probes demonstrated that this retrotransposon is present at low copy number in the C genome, while it is abundant in A, B, and D. The observed differences provide an opportunity for analyzing the putative origin of A. fatua as well as its relationships with other hexaploids. Two marker …

First Karyotype Analysis, Physical Rdna Mapping, And Genome Size Assessment In 4 North African Astragalus Taxa (Fabaceae), Karim Baziz, Meriem Benamara-Bellagha, Fatima Pustahija, Spencer Craig Brown, Sonja Siljak-Yakovlev, Nadra Khalfallah

Turkish Journal of Botany

Four taxa of Algerian Astragalus L. were studied for their chromosome number, karyotype features, and genome size. Fluorochrome banding was done for detection of GC-rich DNA regions, fluorescence in situ hybridization (FISH) for physical mapping of 35S and 5S rRNA genes, and flow cytometry for nuclear DNA content. All the taxa present the same chromosome number (2n = 2x = 16) and single 35S and 5S rDNA loci, but their distributions on chromosomes are different. The GC heterochromatin pattern was different among studied taxa and an unusually high number of chromomycin-positive bands were observed in A. pseudotrigonus Batt. & Trab. …

Synthetic Generators For Simulating Social Networks, Awrad Mohammed Ali

Electronic Theses and Dissertations

An application area of increasing importance is creating agent-based simulations to model human societies. One component of developing these simulations is the ability to generate realistic human social networks. Online social networking websites, such as Facebook, Google+, and Twitter, have increased in popularity in the last decade. Despite the increase in online social networking tools and the importance of studying human behavior in these networks, collecting data directly from these networks is not always feasible due to privacy concerns. Previous work in this area has primarily been limited to 1) network generators that aim to duplicate a small subset of …

Missing The Mark: How Fmla's Bonding Leave Fails Mothers, Rona Kaufman Kitchen

Hofstra Labor & Employment Law Journal

In the two decades since it was adopted, the Family and Medical Leave Act (hereinafter “FMLA” or “the Act”) has been consistently criticized for its failure to achieve its stated goal of enabling workers “to balance the demands of the workplace with the needs of families.” Since it was signed into law in 1993, legal scholars and women’s rights groups, while applauding the accomplishments of the Act, have expressed their dissatisfaction with the status of family and medical leave law in the United States. It has been argued that the FMLA should be expanded to cover more workers, for more …

Youth Violence Prevention Programming In Medellín, Colombia: Five Recommendations, Timothy Pracher

Capstone Collection

This paper presents five evidence-based recommendations for youth violence prevention programming in Medellín, Colombia. The recommendations are based on youth psycho-social needs and prior violence prevention program analyses. Recommendations will suggest that arts and sports activities could be effective programming tools. Historical and contextual information about Colombia's guerrilla war and gang violence in Medellín will be used to demonstrate the importance of youth empowerment programs and explain why a violence prevention program should be implemented in Medellín. The recommendations contained in this paper could be useful for anyone seeking to develop a youth program, especially a youth empowerment program in …

Host-Specialization Of Bartonella In Flea Vectors Collected From Black-Tailed Prairie Dogs, Mark D. Massaro

Honors Theses

At least 22 species of Bartonella bacteria have been named and many are associated with one of a list of potential mammalian reservoirs and arthropod vectors. One example of such a system is the parasitism of black-tailed prairie dogs (Cynomys ludovicianus) of the Western U.S. by Oropyslla hirsuta and Pulex simulans fleas. These vectors are thought to maintain B. washoensis infection in these mammals, but little is known about their role in the specialization of this strain to this reservoir. We found that the more specialist O. hirsuta fleas were much more likely to be infected with B. washoensis than …

Ciliotherapy: A Novel Intervention In Polycystic Kidney Disease, Sarmed H. Kathem, Ashraf M. Mohieldin, Shakila Abdul-Majeed, Sajida H. Ismail, Qaiss H. Altaei, Ibrahim K. Alshimmari, Mohanned M. Alsaidi, Hussein Khammas, Andromeda M. Nauli, Bina Joe, Surya M. Nauli

Pharmacy Faculty Articles and Research

Background Ciliopathies are a group of diseases associated with abnormal structure or function of primary cilia. Ciliopathies include polycystic kidney disease (PKD), a pathology associated with vascular hypertension. We previously showed that cilia length regulates cilia function, and cilia function is required for nitric oxide (NO) biosynthesis in endothelial cells. Because patients with PKD show abnormal sensory cilia function, the aim of our current study was to search for a targeted therapy focused on primary cilia, which we refer to as ‘cilio-therapy’.

Cultivating Human-Nature Relationships: The Role Of Parents And Primary Caregivers In Development Of Environmental Identity, Anne E. Bremer

Pitzer Senior Theses

Industrialized societies have been characterized by a trend of disconnecting humans from our natural environment, leading to environmental and psychological damage. Therefore, in order to work toward repairing such damage, reconnecting humans and the natural environment is critical. One way of conceptualizing human-nature relationships is through “environmental identity,” a term that describes self-identification as part of a larger ecosystem, aesthetic, spiritual, or recreational enjoyment of nature, environmentally positive behaviors, and a social, political, or moral identification with environmentalists. Despite the literature having emphasized childhood experience in nature as being essential to the development of an environmental identity, parental influence in …

A Mother's Paradox: Choosing A Birthing Method In The 21st Century, Jenae Franklin

Pitzer Senior Theses

Investigating childbirth, one of the biggest moments of a woman’s life, this thesis examines the reasons behind women’s preferred birthing methods. This research explores the fundamental decisions women make during the birthing process: the amount of prenatal care mothers will receive, the type of health care provider they will use, picking the place of delivery, views on technological and medical interventions, and outlooks on natural childbirth. In addition to an extensive literature review, in-depth interviews with mothers, midwives, and obstetricians are used to examine the various controversies of childbirth. This thesis begins with a review of the transition from midwives …

Characterizing A Novel Monoclonal Ampa Receptor 1/2/3 Antibody In The Hippocampus And Prefrontal Cortex Of Rat, Monkey, And Human, Sebastian Aguiar

Pitzer Senior Theses

The excitatory, ionotropic glutamatergic AMPA receptor is the most common membrane-bound receptor in the central nervous system. AMPARs and the NMDA receptors are central to synaptic plasticity, memory, and mechanisms of neurodegeneration. The AMPAR is an obligate heterotetramer, composed of subunits GluA1-4. Subunit permutation determines ion conductance, trafficking and other functional characteristics. Few available antibodies are subunit-specific, disabling researchers from accurately visualizing differential AMPAR subunit distribution in the nervous system. This study sought to visualize a novel monoclonal GluA1/2/3 antibody with functional avidity for three of four receptor subunits and to characterize the ultrastructural localization of these receptors using confocal …

Studying The Effect Of Zeolite Inclusion In Aluminum Alloy On Measurement Of Its Surface Hardness Using Laser-Induced Breakdown Spectroscopy Technique, Osama Mostafa Khalil, Ilya Mingareev, Tobias Bonhoff, Ashraf F. El-Sherif, Martin C. Richardson, Mohamed Abdel Harith

Faculty Bibliography 2010s

Laser-induced breakdown spectroscopy (LIBS) has been used to study the surface hardness of special aluminum alloys containing zeolite. The aluminum alloy has acquired pronounced changes in its metallurgical properties due to the zeolite inclusion. The surface hardness of the samples under investigation is determined by measuring the spectral intensity ratios of the ionic to atomic spectral lines in the LIBS spectra of samples having different surface hardness values that have been conventionally measured before for comparison. The presence of aluminum silicate mineral in the studied alloys enabled material volume to expand under compression. This feature gave new results in the …

Optically Induced Forces In Scanning Probe Microscopy, Dana C. Kohlgraf-Owens, Sergey Sukhov, Léo Greusard, Yannick De Wilde, Aristide Dogariu

Faculty Bibliography 2010s

Typical measurements of light in the near-field utilize a photodetector such as a photomultiplier tube or a photodiode, which is placed remotely from the region under test. This kind of detection has many draw-backs including the necessity to detect light in the far-field, the influence of background propagating radiation, the relatively narrowband operation of photodetectors which complicates the operation over a wide wavelength range, and the difficulty in detecting radiation in the far-IR and THz. Here we review an alternative near-field light measurement technique based on the detection of optically induced forces acting on the scanning probe. This type of …

Melatonin-Induced Temporal Up-Regulation Of Gene Expression Related To Ubiquitin/Proteasome System (Ups) In The Human Malaria Parasite Plasmodium Falciparum, Fernando C. Koyama, Mauro F. Azevedo, Alexandre Budu, Debopam Chakrabarti, Célia R. S. Garcia

Faculty Bibliography 2010s

There is an increasing understanding that melatonin and the ubiquitin/ proteasome system (UPS) interact to regulate multiple cellular functions. Post-translational modifications such as ubiquitination are important modulators of signaling processes, cell cycle and many other cellular functions. Previously, we reported a melatonin-induced upregulation of gene expression related to ubiquitin/proteasome system (UPS) in Plasmodium falciparum, the human malaria parasite, and that P. falciparum protein kinase 7 influences this process. This implies a role of melatonin, an indolamine, in modulating intraerythrocytic development of the parasite. In this report we demonstrate by qPCR analysis, that melatonin induces gene upregulation in nine out of …

Thermoregulatory Strategy May Shape Immune Investment In Drosophila Melanogaster, Ian C. Kutch, Hasan Sevgili, Tyler Wittman, Kenneth M. Fedorka

Faculty Bibliography 2010s

As temperatures change, insects alter the amount of melanin in their cuticle to improve thermoregulation. However, melanin is also central to insect immunity, suggesting that thermoregulatory strategy may indirectly impact immune defense by altering the abundance of melanin pathway components (a hypothesis we refer to as thermoregulatory-dependent immune investment). This may be the case in the cricket Allonemobius socius, where warm environments (both seasonal and geographical) produced crickets with lighter cuticles and increased pathogen susceptibility. Unfortunately, the potential for thermoregulatory strategy to influence insect immunity has not been widely explored. Here we address the relationships between temperature, thermoregulatory strategy and …

The Ct20 Peptide Causes Detachment And Death Of Metastatic Breast Cancer Cells By Promoting Mitochondrial Aggregation And Cytoskeletal Disruption, M. W. Lee, R. Bassiouni, N. A. Sparrow, A. Iketani, R. J. Boohaker, C. Moskowitz, P. Vishnubhotla, A. S. Khaled, J. Oyer, A. Copik, C. Fernandez-Valle, J. M. Perez, A. R. Khaled

Faculty Bibliography 2010s

Metastasis accounts for most deaths from breast cancer, driving the need for new therapeutics that can impede disease progression. Rationally designed peptides that take advantage of cancer-specific differences in cellular physiology are an emerging technology that offer promise as a treatment for metastatic breast cancer. We developed CT20p, a hydrophobic peptide based on the C terminus of Bax that exhibits similarities with antimicrobial peptides, and previously reported that CT20p has unique cytotoxic actions independent of full-length Bax. In this study, we identified the intracellular actions of CT20p which precede cancer cell-specific detachment and death. Previously, we found that CT20p migrated …

The Effect Of Normally Consumed Amounts Of Sucrose Or High Fructose Corn Syrup On Lipid Profiles, Body Composition And Related Parameters In Overweight/Obese Subjects, Joshua Lowndes, Stephanie Sinnett, Sabrina Pardo, Von T. Nguyen, Kathleen J. Melanson, Zhiping Yu, Britte E. Lowther, James M. Rippe

Faculty Bibliography 2010s

The American Heart Association (AHA) has advocated that women and men not consume more than 100 and 150 kcal/day, respectively, from added sugars. These levels are currently exceeded by over 90% of the adult population in the United States. Few data exist on longer-term metabolic effects when sucrose and High Fructose Corn Syrup (HFCS), the principal sources of added dietary sugars, are consumed at levels typical of the general population. Sixty five overweight and obese individuals were placed on a eucaloric (weight stable) diet for 10-weeks, which incorporated sucrose- or HFCS-sweetened, low-fat milk at 10% or 20% of calories in …
