Induction Of Abnormal Sperm Heads In Small Mammals Under Chronic Ionizing Radiation, Lyudmila Bashlykova, Oksana Raskosha, Natalia Starobor

Turkish Journal of Zoology

The results of this study show a mutagenic effect of low-dose ionizing radiation in male germ cells. The damage of male germ cells was assessed by the frequency of abnormal sperm heads in tundra voles (Microtus oeconomus Pall.), bank voles (Myodes glareolus Schreb.), and field mice (Apodemus agrarius Pall.) from the 30 km exclusion zone around the Chernobyl nuclear power station and for laboratory animals (mice and rats) under chronic γ-irradiation. The abnormal sperm head detection method used appeared to be sensitive to conditions of low-dose irradiation and can consequently be recommended as a bioindicator to monitor environmental radiation pollution.

Validation Of Reference Genes For Quantitative Expression Analysis By Qpcr In Various Tissues Of Date Mussel (Lithophaga Lithophaga), Urska Sivka

Turkish Journal of Zoology

qPCR is a very popular method for identifying nucleotide sequences as a result of its sensitivity and relatively low cost and technical simplicity. Normalization is one of the most important steps in analyzing qPCR data and the use of reference genes is the most common normalization strategy. In the present study five commonly used reference genes (18S, 28S, ef1a, ß-act, and ?-tub) were evaluated for their stability in the mantle, gill, foot, and pallial gland of date mussel (L. lithophaga) in different seasons. Four different software packages were used for evaluation: geNorm, NormFinder, BestKeeper, and RefFinder. Although these programs contain …

Acute And Chronic Effects Of Thifluzamide On Daphnia Magna, Feyza İçoğlu Aksakal

Turkish Journal of Zoology

Thifluzamide is a thiazole carboxanilide fungicide used to control a wide range of basidiomycete diseases on maize, potatoes, rice, and other crops. Although this fungicide is found in aquatic environments, there is no information about its acute and chronic toxicity on aquatic invertebrates. In the present study, to investigate acute and chronic toxicity of thifluzamide, daphnids were exposed to 1.25, 1.5, 2, and 2.5 mg/L thifluzamide for 48 h and 21 days, respectively. The expression of four oxidative stress-related genes (CAT, GCLC, GST, and GPX) and life-history parameters such as days to the first brood, days to the first egg …

Pelvic And Sacral Size Dimorphism And Allometry In Two Predatory Carnivores With Different Life Histories And Locomotory Adaptations, Alexander Csanady, Peter Krisovsky, Ladislav Hloska

Turkish Journal of Zoology

Sexual size dimorphism (SSD) of the wolf and the lynx was evaluated for 15 pelvic and sacral variables in 48 specimens from the Western Carpathians. Our data confirmed small male-biased SSD in the pelvic and sacral bones for both species. We suggest that this can be explained by the need for a compromise between requirements for locomotion and giving birth. We also confirmed that significant differences exist between the species in the size of the pelvic and sacral bones. We discuss our findings in light of the species? different life histories.

On Tooth Anomalies And The Loss Of Canis Lupus (Mammalia: Carnivora) In Turkey, Eli̇f Yildiz Ay, İrfan Albayrak

Turkish Journal of Zoology

Because of their feeding habits, which are affected by their ranking in the last steps of the food chain, the teeth of carnivores are subjected to great forces during the breaking up and chewing of food when they are hunting. In this sense, missing teeth and tooth anomalies are common in carnivores. This research was based on an examination of the properties of the tooth structures of 25 wolf specimens collected in Turkey between 2014 and 2018. In this study, the excess and missing teeth, tooth fracture, and root anomalies in the lower and upper jaw of the head skeletons …

Phylogenetic Relationship Among Slender Loris Species (Primates, Lorisidae: Loris) In Sri Lanka Based On Mtdna Co1 Barcoding, Saman Gamage, Faiz Marikar, Colin Groves, Craig Turner, Kalinga Padmalal, Sarath Kotagame

Turkish Journal of Zoology

There are 2 species of slender lorises found in Sri Lanka: the red slender loris, Loris tardigradus (Linnaeus, 1758), endemic to the wet zone and montane areas, and the grey slender loris, Loris lydekkerianus (Cabrera, 1908), which is widespread. In addition, currently there are 2 subspecies recognized for each of these 2 slender loris species of Sri Lanka. Yet their taxonomy, evolutionary history, and biogeography are still poorly understood, and there are some preliminary data suggesting the presence of other subspecies. In this study, we have analysed the partial mitochondrial cytochrome oxidase I gene sequence of 21 Loris specimens collected …

Possible Expansion Of The Range Of Xylocopa Violacea L. (Hymenoptera, Apiformes, Apidae) In Europe, Józef Banaszak, Weronika Banaszak Cibicka, Lucyna Twerd

Turkish Journal of Zoology

The violet carpenter bee is a species which can chiefly be found around the Mediterranean Sea and the Black Sea. This bee species has rarely been found in Poland, which is the northernmost area of its occurrence. Between 1868 and 1935, the Xylocopa violacea (Linnaeus, 1758) was observed at only 8 locations in Poland. There were then no reports of the occurrence of this bee species in Poland for 70 years. The species was noted again in 2005; between 2005 and 2017, it was noted at 20 locations. This study provides detailed data on the history of the distribution of …

Full-Length Human Cytomegalovirus Terminase Pul89 Adopts A Two-Domain Structure Specific For Dna Packaging, Janine Theiß, Min Woo Sung, Andreas Holzenburg, Elke Bogner

School of Medicine Publications

A key step in replication of human cytomegalovirus (HCMV) in the host cell is the generation and packaging of unit-length genomes into preformed capsids. The enzymes involved in this process are the terminases. The HCMV terminase complex consists of two terminase subunits, the ATPase pUL56 and the nuclease pUL89. A potential third component pUL51 has been proposed. Even though the terminase subunit pUL89 has been shown to be essential for DNA packaging and interaction with pUL56, it is not known how pUL89 mechanistically achieves sequence-specific DNA binding and nicking. To identify essential domains and invariant amino acids vis-a-vis nuclease activity …

Molecular Mechanism Of Cancer Susceptibility Associated With Fok1 Single Nucleotide Polymorphism Of Vdr In Relation To Breast Cancer, Sana Raza, Anupam Dhasmana, Madan Lal Brahma Bhatt, Mohtashim Lohani, Jamal M. Arif

School of Medicine Publications

Breast cancer is the leading cause of death among women worldwide. It is a multi-factorial disease caused by genetic and environmental factors. Vitamin D has been hypothesized to lower the risk of breast cancer via the nuclear vitamin D receptor (VDR). Genetic variants of these vitamin D metabolizing genes may alter the bioavailability of vitamin D, and hence modulate the risk of breast cancer. Materials and Methods: The distribution of Fok1 VDR gene (rs2228570) polymorphism and its association with breast cancer was analysed in a case–control study based on 125 breast cancer patients and 125 healthy females from North Indian …

Environmental And Genetic Correlations Between The Metabolic Syndrome (Ms) And System Variables Representing Adaptive Immunity, Innate Immunity And Hemostasis, Jewel Udenwagu, Unyime-Abasi Eyobio, Stephanie Onyechi, Vincent P. Diego, Marcio A. Almeida, Tom E. Howard, John Blangero

School of Medicine Publications

The MS is prevalent in Mexican Americans (MAs) and is projected to increase. It is important therefore to better understand its genetic and environmental determinants. We hypothesized that the MS reflects dysfunction in important biological systems. To evaluate this concept, we analyzed gene expression data for the adaptive-immune, innate-immune, and hemostasis systems in relation to the MS from a study on MAs of San Antonio and the Rio Grande Valley.

The Power Of Prevention: The Extent Of Environmental Authority In The Context Of Local Government, Colleen Thrasher, Jeremy Power

Dalhousie Journal of Legal Studies

This article attempts to delineate the scope of a municipality’s legal power within the realm of environmental management. Part one of this article looks at the legal position of a municipal government in the Canadian constitutional framework. The authors note that municipalities are creatures of statute and their available powers are tightly prescribed by legislation. Part two of this article is a case study of the City of Toronto's efforts to manage pollution in the Great Lake region, particularly with respect to Lake Ontario. Despite the limits to a municipality’s power, the authors argue that many effective pollution prevention strategies …

Progressive And Populist Strands In American Constitutionalism, Louis Michael Seidman

Georgetown Law Faculty Publications and Other Works

Many modern liberals believe that the federal government is captured by a “billionaire party” determined to wield public power for private gain. But many of them also believe in giving the federal government greatly enhanced powers, like administering “Medicare for all.”

There is a history to this contradiction. Modern liberalism is an amalgam of older populist and progressive impulses with deep roots in the country’s past. The populist impulse locates the source of economic oppression in government corruption. The solution to this problem is direct, popular democracy. Progressives tend to locate the source of economic oppression in the malfunction of …

Janet Halley And The Art Of Status Quo Maintenance, Lama Abu-Odeh

Georgetown Law Faculty Publications and Other Works

Over the past few years, Janet Halley emerged as one of the most avid critics of campus rape feminist activists, activists who push for the reformulation of university investigative rules to shift the burden of proof from the accuser to the accused. Halley contends that Title IX policies, embedded with affirmative consent, are not only procedurally unsound, but bad for boys, bad for sex, and bad for feminism, charging its agenda with “radical feminism” influences. Halley’s stance on campus rape is consistent with her long-held “queer theory” and its anti-feminist deregulatory drive. In this article, I argue that Halley’s “queer …

Non-Contact Trapping And Stretching Of Biological Cells Using Dual-Beam Optical Stretcher On Microfluidic Platform, Aotuo Dong, Balaadithya Uppalapati, Shariful Islam, Brandon Gibbs, Ganesan Kamatchi, Sacharia Albin, Makarand Deo

Electrical & Computer Engineering Faculty Publications

Optical stretcher is a tool in which two counter-propagating, slightly diverging, and identical laser beams are used to trap and axially stretch microparticles in the path of light. In this work, we utilized the dual-beam optical stretcher setup to trap and stretch human embryonic kidney (HEK) cells and mammalian breast cancer (MBC) cells. Experiments were performed by exposing the HEK cells to counter-propagating laser beams for 30 seconds at powers ranging from 100 mW to 561 mW. It was observed that the percentage of cell deformation increased from 16.7% at 100 mW to 40.5% at 561 mW optical power. The …

Effects Of Cell Morphology And Attachment To A Surface On The Hydrodynamic Performance Of Unicellular Choanoflagellates, Hoa Nguyen, M. A. R. Koehl, Christian Oakes, G. Bustamente, L. Fauci

Mathematics Faculty Research

Choanoflagellates, eukaryotes that are important predators on bacteria in aquatic ecosystems, are closely related to animals and are used as a model system to study the evolution of animals from protozoan ancestors. The choanoflagellate Salpingoeca rosetta has a complex life cycle with different morphotypes, some unicellular and some multicellular. Here we use computational fluid dynamics to study the hydrodynamics of swimming and feeding by different unicellular stages of S. rosetta: a swimming cell with a collar of prey-capturing microvilli surrounding a single flagellum, a thecate cell attached to a surface and a dispersal-stage cell with a slender body, long …

Rethinking Public Land Use Planning, Mark Squillace

Publications

The public land use planning process is broken. The land use plans of the principal multiple-use agencies—the United States Forest Service and the Bureau of Land Management (“BLM”)—are unnecessarily complex, take too long to complete, monopolize the time and resources of public land management agency staffs, and fail to engage the general public in any meaningful way. Moreover, the end result is too often a plan that is not sufficiently nimble to respond to changing conditions on the ground, a problem that appears to be accelerating due to climate change.

It might seem easy to chalk up these problems to …

Sustainable Development: Energy, Justice, And Women, Lakshman Guruswamy

Publications

This article will first offer a functional synopsis relevant to its remit, of the concept of sustainable development (SD) embodied in international law and policy that reflects a tension between economic and social claims as contrasted with environmental protection. While the dominant place acquired by the economic and social dimensions of SD will be recognized, it will argue consistent with the predicate of justice discussed in the article, that the protection of the human environment encompasses the plight of the energy poor and their women and children. Second, the article will delineate the contours of one of the great developmental …
