Analyzing Prominent Genes In Acute Lymphocytic Leukemia (All), Shima Z. Omar

Honors College Theses

Acute lymphocytic leukemia (ALL) is the most common type of childhood cancer. Leukemia is a type of cancer that involves the bone marrow and blood. This research study examined prominent genes in the disease. Two groups of genes, tumor suppressor and cell differentiation, were compared using statistical analysis to compare their binding potential and epigenetic potential. It is most likely that I failed to detect significant differences either because these genes’ function in the disease etiology is not strongly contexed to changes in expression, or that the magnitude of the differences were too slight to be detected with these methods. …

Exploring The Dynamic Reading Of Environment Towards A Multidimensional Legibility, Putri Mahsa Gantari, Ferro Yudistira

ARSNET

This study investigates the understanding of legibility, defined as the coherency of built environment features. Legibility enables production of mental image that helps individuals with their spatial navigation. The current discussion positions legibility as an objective aspect in the process of making sense of the environment. The study argues that such a process has dynamics that reflect individuals' subjectivity, therefore further study is important to reconcile the objective and subjective reading of legibility. This research qualitatively investigates legibility using a case study of an indoor environment of a shopping mall in East Jakarta. The analysis was conducted based on the …

Iranian Music, Silence, And The Representation Of The Traditional Masculine Figure Of The Pahlavan: A Case Study Of "Dash Akol" (1971), Kamyar Salavati

Regards

The Persian term pahlavan represents an archetypal character of a strong man who is generous, uncorrupted, and humble in the face of weakness. This paper will focus on sonic aspects of the pahlavan by zooming in on one of Masoud Kimiai’s films, Dash Akol (1971), which is based on a story of the same name by Sadegh Hedayat. First, I will concentrate on how the movie links heroic masculinity to the Persian classical music mode Chahargah and the instrument tombak-e zurkhaneh, and contrasts it with the tragic and romantic associations of Dashti, another Persian classical mode, representing another, …

Multiple Light Signaling Pathways Control Solar Tracking In Sunflowers, Christopher J. Brooks, Hagop S. Atamian, Stacey L. Harmer

Biology, Chemistry, and Environmental Sciences Faculty Articles and Research

Sunflowers are famous for their ability to track the sun throughout the day and then reorient at night to face east the following morning. This occurs by differential growth patterns, with the east sides of stems growing more during the day and the west sides of stems growing more at night. This process, termed heliotropism, is generally believed to be a specialized form of phototropism; however, the underlying mechanism is unknown. To better understand heliotropism, we compared gene expression patterns in plants undergoing phototropism in a controlled environment and in plants initiating and maintaining heliotropic growth in the field. We …

Osc-Co2: Coattention And Cosegmentation Framework For Plant State Change With Multiple Features, Rubi Quiñones, Ashok Samal, Sruti Das Choudhury, Francisco Muñoz-Arriola

School of Computing: Faculty Publications

Cosegmentation and coattention are extensions of traditional segmentation methods aimed at detecting a common object (or objects) in a group of images. Current cosegmentation and coattention methods are ineffective for objects, such as plants, that change their morphological state while being captured in different modalities and views. The Object State Change using Coattention-Cosegmentation (OSC-CO²) is an end-to-end unsupervised deep-learning framework that enhances traditional segmentation techniques, processing, analyzing, selecting, and combining suitable segmentation results that may contain most of our target object’s pixels, and then displaying a final segmented image. The framework leverages coattention-based convolutional neural networks (CNNs) and …

Effects Of A Major Hurricane On Dynamics, Structure, And Composition Of Mississippi River Delta Forests, Lance C. Umlang

LSU Doctoral Dissertations

Tropical cyclones recurrently influence coastal forests worldwide. Tree survival (resistance) and post-cyclone recruitment (resilience) can vary with cyclone intensity, producing differences in composition, arboreal structure, and dynamics among affected forests. Studies of tropical cyclone wind effects on coastal forests typically emphasize damage more than post-cyclone responses. We hypothesized that intense cyclones might produce large, stratum-dependent effects that prevent affected forests from returning to pre-storm conditions. We explored direct effects of major Hurricane Katrina and post-hurricane changes in oak-dominated bottomland and cypress/tupelo-dominated swamp forests within the inactive portion of the Mississippi River deltaic plain. Overall mortality was high (14-25%) but concentrated …

BACKGROUND: Subgroup analyses in clinical trials assess intervention effects on specific patient subgroups, ensuring generalizability. However, they are usually only able to generate hypotheses rather than definitive conclusions. This study examined the prevalence and characteristics of post hoc subgroup analysis in oncology.

METHODS: We systematically reviewed published subgroup analyses from 2000 to 2022. We included articles presenting secondary, post hoc, or subgroup analyses of interventional clinical trials in oncology, cancer survivorship, or cancer screening, published separately from the original clinical trial publication. We collected cancer type, year of publication, where and how subgroup analyses were reported, and funding.

Water-Soluble Phthalocyanine Photosensitizers For Photodynamic Therapy, İpek Ömeroğlu, Mahmut Durmuş

Turkish Journal of Chemistry

Photodynamic therapy (PDT) is based on a photochemical reaction that is started when a photosensitizing process is activated by the light and results in the death of tumor cells. Solubility is crucial in PDT applications to investigate the physical and chemical characteristics of phthalocyanines, but, unfortunately, most phthalocyanines show limited solubility especially in water. To increase the solubility of phthalocyanines in polar solvents and water, ionic groups such as -SO3 - , -NR3 +, -COO- , and nonionic groups such as poly-oxy chains are frequently added to the peripheral or nonperipheral positions of the phthalocyanine framework. Since water-solubility and NIR-absorbing …

Kewarganegaraan Inklusif: Menempatkan Model Budaya Disabilitas Dalam Teori Multikultural Liberal Will Kymlicka, Hanandhia Lindsy Rustam, Lg. Saraswati Putri

Multikultura

Tulisan ini bertujuan untuk menggambarkan cultural model of disability atau model budaya disabilitas dalam teori multikultural liberal Will Kymlicka. Status kewarganegaraan disabilitas seringkali masih diturunkan menjadi kewarganegaraan pasif atau parsial yang patut dikasihani dan mendapat perhatian paternalistik. Kemunculan advokasi disabilitas sebagai hak kelompok dan bukan hak individu baru-baru ini menuntut kita untuk mengevaluasi secara lebih menyeluruh konsepsi disabilitas sebagai sebuah kelompok non-etnis namun bersifat budaya yang menegosiasikan tempat mereka di wilayah negara. Model budaya disabilitas inilah yang sejalan dengan tujuan teori multikultural liberal Will Kymlicka yang menyatakan bahwa masyarakat yang beragam membutuhkan lebih dari sekedar akses yang setara dan hak-hak …
