Turkish Journal of Zoology

Increasing plastic pollution has become a critical environmental issue, leading to  challenges in management. Specifically, microplastics (MPs) are of particular concern  because they can persist in aquatic ecosystems and adversely affect marine  organisms. The objective of this study was to assess the occurrence of MPs  in the soft tissues of Patella caerulea (Linnaeus, 1758) collected from the Mersin  Viranşehir coastal area. As no specimens were found in the supralittoral zone, the  decision was taken to conduct sampling only in the mediolittoral and infralittoral  zones. The total sampling area was 24 m2 divided into three 4-m2 plots in each zone.  A …

Blinking Without Eyelids: First Video-Documented Evidence Of A Blink-Like Reflex In Ophisops Elegans (Reptilia: Lacertidae), Turan Meri̇ç Çelebi̇, Yusuf Çeli̇kaği, Tuana Kinay, Arda Cem Kuyucu, Muammer Kurnaz, Mehmet Kürşat Şahi̇n

Turkish Journal of Zoology

Eyelids play a crucial role in protecting the eyes of vertebrates; however, certain  reptile species, such as Ophisops elegans, completely lack movable eyelids. In this  study, we present the first video-documented evidence of a blink-like reflex in O.  elegans, captured through endoscopic field observations and corroborated by laboratory video analysis. The observed movement consisted of a brief convex  deformation of the ocular surface, lasting approximately 0.3 s and resembling a blink  despite the presence of a fixed transparent brille. This behavior was observed once in  the field and twice under controlled laboratory conditions. We propose that O.  elegans may employ …

School of Integrative Biological & Chemical Sciences Faculty Publications

Citrus canker, caused by bacterium Xanthomonas citri subsp. citri (Xcc), affects the citrus industry by making the fruit unmarketable due to unsightly lesions on the fruit. Citrus canker caused by a relatively new AWstrain of Xcc was reported on the citrus trees in the residential areas of the Lower Rio Grande Valley (LRGV) of South Texas. Xcc AW has a limited host range, predominantly affecting limes and a few other citrus species. Previous work has reported prevailing environmental conditions that influence the incidence and spread of the citrus canker caused by the Asiatic A strain. However, no information is available …

Habitat Diversity Or Altitudinal Gradient? Which Factor Better Explains Ground Beetle (Coleoptera: Carabidae) Biodiversity? A Case Study From Davraz Mountain (Isparta, Türkiye), Ebru Ceren Fi̇dan, Ali̇ Gök

Turkish Journal of Zoology

Ground beetle (Carabidae) species diversity and spatial distribution were surveyed  across five habitat types along an elevational gradient on Davraz Mountain, a  biogeographical transition area in southwestern Türkiye. The analyses showed that  habitat heterogeneity—particularly soil moisture and texture—exerts a stronger  influence on carabid diversity than elevation. Sørensen’s and Jaccard similarity  indices showed strong faunal overlap between some sampling areas, while  multivariate principal components and canonical correspondence analyses verified  distinct environmental gradients influencing community structure. Diversity indices  indicated varying levels of species richness and evenness across sampling areas.  The data highlight the importance of fine-scaled habitat features in driving ground  beetle …

Turkish Journal of Zoology

The common sunbleak (Leucaspius delineatus) is an invasive fish found in Siberian  water bodies, the trophic interactions and impact on local ecosystems of which  remain poorly understood. Traditional diet analyses are limited by the mechanical  damage to the prey. For the present study, therefore, we employed DNA  metabarcoding of the cytochrome c oxidase I (cox1) gene to analyze the digestive  tract contents of the common sunbleak obtained from Irkutsk Reservoir. Our analysis  revealed 53 operational taxonomic units (OTUs), with sequences of amphibiotic  insects (58.66%) and fish (34.10%) being the most prevalent. A significant proportion  of the fish DNA, including sequences …

Distribution Of Mussels In Two Intermittent Upland Streams Of The Arkansas Valley Ecoregion, A. A. Brady, K. B. Hecke, S. A. Drake, Z. R. Crain, K. Moles

Journal of the Arkansas Academy of Science

Freshwater mussels are facing an increasing need for conservation due to their declining populations. More data is needed on mussel distributions, especially in tributaries of large rivers to properly conserve and restore populations. Big Shoal Creek and Little Shoal Creek are two upland-tributaries of the Arkansas River (Lake Dardanelle) in which no records exist for freshwater mussel populations. We addressed this knowledge gap by sampling a total of 9 sites in Little Shoal Creek and 18 sites in Big Shoal Creek to determine the abundance and distribution of mussels in these streams. Mussels were sampled using a timed-search approach. A …

Transient Grating Spectroscopy Nondestructively Characterizes The Mechanics Of Rubbery Polymers And Soft Gels, Christopher W. Barney, Angela A. Pitenis, Bolin Liao, Allison L. Chau

University Research

Designing efficient mechanisms for moving mechanical assemblies requires the use of materials with well-defined mechanical responses. Appropriate methods are needed to characterize these mechanical responses. Mechanical characterization of soft materials is critical in the high strain rate regime where intuition from manipulating a material at low rates fails to translate to applications including impact protection, tire traction, and sound damping. Here, transient grating spectroscopy (TGS) is used to measure wave propagation for soft elastomers and hydrogels. TGS is a non-destructive and non-contact optoacoustic technique that enables high strain rate measurements of the bulk modulus, a measure of a material's resistance …

Atherogenic Index Of Plasma’S Association With Coronary Heart Disease Risks Among Postmenopausal Pakistani Women, Amad Khan, Syed Kashif Raza

Journal of Social, Behavioral, and Health Sciences

Coronary heart disease (CHD) is a leading global cause of mortality, notably affecting postmenopausal women. Hormonal fluctuations during menopause contribute to dyslipidemia, fostering cardiovascular disease (CVD). This study explored lipid profiles among postmenopausal Pakistani women, focusing on the atherogenic index of plasma (AIP) and its association with CHD.

The data consisted of surveys from 265 women aged between 40–70 years. A STEP-wise approach, using a questionnaire from the World Health Organization, was employed for data collection. This quantitative cross-sectional study, guided by the socioecological model, examined links between AIP, age, lipid profiles, and hypertension. The AIP’s association with CHD was …

Reprioritizing International Patent Law, John R. Thomas

Georgetown Law Faculty Publications and Other Works

Over the past half-century, rapid technological change and globalization have reshaped innovation and intellectual property, yet the foundational international agreements anchoring the global patent system have remained essentially unchanged. The drafters of the Paris Convention for the Protection of Industrial Property and the Patent Cooperation Treaty (PCT) viewed these agreements as dynamic instruments that, through procedural coordination, would rationalize international patent administration. The Paris Convention has resisted reform for decades, however, while the PCT has failed to achieve its goals of reducing examination workloads and fostering worksharing among national patent offices. It now exacerbates the very inefficiencies it sought to …

Intralabyrinthine Mri Flair As A Predictive Marker For Hearing Loss In Vestibular Schwannomas In Neurofibromatosis Type 2, Robert L. Walker, Maxwell T. Laws, H. Jeffrey Kim, Christopher Zalewski, Ashok Asthagiri, Sruthi Ranganathan, Christina Hayes, John D. Heiss, John A. Butman, Prashant Chittiboina

Department of Radiation Oncology Faculty Papers

BACKGROUND AND OBJECTIVES: The onset of hearing loss due to vestibular schwannomas (VS) is inevitable but does not correlate with the size of the tumor. In patients with Neurofibromatosis Type 2 (NF2) and VS, we previously found an association between pre-contrast fluid-attenuated inversion recovery magnetic resonance imaging (FLAIR MRI) signal in the labyrinth and hearing loss. Here, we asked whether FLAIR hyper-intensity could serve as a predictive biomarker for hearing loss in NF2 patients with VS.

METHODS: A prospective longitudinal study (NCT00598351) of NF2 enrolled 168 subjects between 2008 and 2013. This study included 34 patients with small VS (total …

From Private Custody To Public Policy: The Politics Of State Responsibility For Post-Divorce Abandoned Children (Hadhanah) In Serang, Indonesia, Ali Faisal, Naf’An Tarihoran, B Syafuri, Nurul Ma’Rifah

Jurnal Wacana Politik

This article examines how hadhanah (child custody and care) can be reframed from a private family matter into a public policy issue, positioning the state as a responsible actor when children become abandoned after divorce. Drawing on a normative–juridical and qualitative socio-legal analysis of Islamic family law, national legislation, and municipal policy instruments, the study uses Serang City as an illustrative case of policy urgency. The findings demonstrate a systematic implementation gap between Indonesia’s constitutional mandate to care for abandoned children and local-level governance practice: (1) a legal–administrative gap, where court-based custody decisions and parental obligations do not automatically trigger …

Early Detection Of Bladder Cancer Using Advanced Feature Engineering And Swarm Intelligence Optimization On Ehrs, Xu Wang, Andrea Preston, Jonathan Aning, Michael Loizou, Shang-Ming Zhou

School of Nursing and Midwifery

Background: Bladder cancer (BC) symptoms often overlap with benign conditions, while no routine screening exists for general population. We aim to develop a machine learning (ML)-based screening pipeline for early BC detection using electronic-health-records (EHRs) in primary care. Methods: A multi-centred case-control cohort (1995–2018; n = 64,884) was created for model training and testing. We further validated the model prospectively on an independent cohort (2019–2020; n = 4,569). We proposed the Parsimony driven REweighting for Calibrated Input-based Screening for Early detection—Adjustable Grey Zone (PRECISE-AGZ), which identified influential features from 48,261 candidates and developed a calibrated logistic regression screening model with …

An Antioxidant Cocktail Of Tert-Butylhydroquinone And A Manganese Porphyrin Induces Toxic Levels Of Oxidative Stress In Cancer Cells, Sandra Tamarin, Hannah Jung, Joseph Lamorte, Laura Biesterveld, Gabriel Piñero, Grace Turchetta, Molly Myers, Rebecca Oberley-Deegan, Aimee Eggler

Student Papers, Posters & Projects

Despite significant advancement in cancer treatments, therapies with minimal toxicity to healthy cells are still limited. One targetable weakness of cancer cells is their sensitivity to oxidative stress. We find that the combination of two antioxidants—the common food additive tert-butylhydroquinone (tBHQ) and a manganese porphyrin in clinical trials, MnTnBuOE-2-PyP5+ (MnBuOE)—increases oxidative stress and causes apoptotic death in several cancer cell lines, but not in mouse primary fibroblasts. Investigating the mechanism of cell death, MnBuOE is observed to catalyze the oxidation of tBHQ, producing the electrophilic quinone tert-butylquinone (tBQ). A critical role for tBQ and its electrophilic character was revealed with …
