The Effect Of Pistacia Terebinthus Extract On Lipid Peroxidation, Glutathione,Protein, And Some Enzyme Activities In Tissues Of Rats Undergoing Oxidative Stress, Semra Türkoğlu, Sai̇t Çeli̇k, Serhat Keser, İsmai̇l Türkoğlu, Ökkeş Yilmaz Jan 2017

The Effect Of Pistacia Terebinthus Extract On Lipid Peroxidation, Glutathione,Protein, And Some Enzyme Activities In Tissues Of Rats Undergoing Oxidative Stress, Semra Türkoğlu, Sai̇t Çeli̇k, Serhat Keser, İsmai̇l Türkoğlu, Ökkeş Yilmaz

Turkish Journal of Zoology

This study measures the effects of Pistacia terebinthus flower extract on the amounts of lipid peroxidation (LPO), total protein, glutathione, and enzyme activities in blood. It also measures the effects of the plant extract on glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) enzyme activities and it arrives at the conclusion that GSH-Px activity significantly increased in the Pistacia terebinthus-hydrogen peroxide group (P < 0.0001) and SOD activity meaningfully increased in the Pistacia terebinthus (P < 0.05) and Pistacia terebinthus-hydrogen peroxide (P < 0.0001) groups. It is also found that P. terebinthus extract has protective effects against LPO exerted in the kidney, brain, and lungs (P < 0.0001). The positive effects of P. terebinthus extract are also found on the levels of glutathione and total protein in all organs, except for the level of glutathione in the spleen and brain, and the increase of glutathione and total protein (P < 0.0001). These results are parallel to the effect of the extract used in this study on the LPO levels in tissues and they show that the plant species used in the study has positive effects on the activities of antioxidant molecules as well as protective effects against LPO.

Ephemeroptera, Plecoptera, And Trichoptera Assemblages Of Karst Springs In Relationto Some Environmental Factors: A Case Study In Central Bosnia And Herzegovina, Ana Savic, Dejan Dmitrovic, Vladimir Pesic

Turkish Journal of Zoology

In this study we analyzed changes of Ephemeroptera, Plecoptera, and Trichoptera (EPT) assemblages in 50 springs along the Cvrcka River mainstream in central Bosnia and Herzegovina. Springs were divided into 3 groups: rheocrene, rheopsammocrene, and piped springs. The objectives of our survey were to analyze changes in EPT communities in response to some environmental factors and anthropogenic activities. Twenty-eight morphologically distinct taxa were identified. EPT diversity was positively correlated to discharge and areal coverage of sand and stones but negatively correlated with areal coverage of algae. Canonical correspondence analysis revealed that the most important factors in structuring EPT spring assemblages …

The Incidence Of Rare Males In Seven Parthenogeneticartemia (Crustacea: Anostraca) Populations, Muhammad Saleem Chang, Alireza Asem, Shichun Sun Jan 2017

The Incidence Of Rare Males In Seven Parthenogeneticartemia (Crustacea: Anostraca) Populations, Muhammad Saleem Chang, Alireza Asem, Shichun Sun

Turkish Journal of Zoology

Males that present infrequently in parthenogenetic Artemia are commonly called "rare males". By rearing cloned parthenogenetic Artemia in the laboratory, the frequency of rare males was observed for seven Artemia populations with different ploidy compositions. The results showed that the values of the male:female ratio varied from 0.53:1000 to 1.40:1000 in diploids from different populations, and there were significant differences among populations and clones. No rare males were found in any of the 46 polyploid clones (217,197 individuals) observed.

Cautions About Precautions, Jay R. Stauffer Jr. Jan 2017

Cautions About Precautions, Jay R. Stauffer Jr.

Animal Sentience

Assuming an animal to be sentient in the absence of conclusive evidence to the contrary is an extreme position, hence it should not and could not be the default assumption. Birch explains how the precautionary principle may be used to substantiate decisions to give the animal the benefit of doubt. Although I am reluctant to accept all of his points, Birch has provided an excellent argument for the use of the precautionary principle for the detection of animal sentience. I agree that more research is needed to refine and understand this relationship.

Justifying The Precautionary Principle With Expected Net-Welfare Maximization, Yew-Kwang Ng Jan 2017

Justifying The Precautionary Principle With Expected Net-Welfare Maximization, Yew-Kwang Ng

Animal Sentience

The precautionary principle may be best justified on the principle of expected net-welfare/benefit maximization; there is no conflict between the two principles. We should want to be more cautious for cases with high benefit-to-cost ratios; there should thus be different degrees of precaution. For measures to reduce extinction-threatening environmental disruption or to reduce animal suffering that cost us little or nothing, we should adopt them even for species having only a small likelihood of being sentient, i.e., we should be more cautious. This argument is based on welfarism, which I strongly defend elsewhere (Ng 1990 & forthcoming).

Not Statistically Significant, But Still Scientific, Rachael L. Brown Jan 2017

Not Statistically Significant, But Still Scientific, Rachael L. Brown

Animal Sentience

Birch’s formulation is persuasive but not nuanced enough to capture at least one situation where it is reasonable to invoke the precautionary principle (PP): when we have multiple, weak, but convergent, lines of evidence that a species is sentient, but no statistically significant evidence of a single credible indicator of sentience within the order as required by BAR. I respond to the worry that if we include such cases in our framework for applying the PP, we open ourselves to the charge of being “unscientific.”

Red Snapper Distribution On Natural Habitats And Artificial Structures In The Northern Gulf Of Mexico, Mandy Karnauskas, John F. Walter Iii, Matthew D. Campbell, Adam G. Pollack, J. Marcus Drymon, Sean P. Powers

University Faculty and Staff Publications

In 2011, an intensive, multiple-gear, fishery-independent survey was carried out in the northern Gulf of Mexico (GOM) to collect comprehensive age and length information on Red Snapper Lutjanus campechanus. Based on this synoptic survey, we produced a spatial map of Red Snapper relative abundance that integrates both gear selectivity effects and ontogenetically varying habitat usage. Our methodology generated a spatial map of Red Snapper at a 10-km2 grid resolution that is consistent with existing knowledge of the species: Red Snapper occurred in relatively high abundances at depths of 50–90 m along the coasts of Texas and Louisiana and in smaller, …

Department of Electrical and Computer Engineering: Faculty Publications

Colour produced by wavelength-dependent light scattering is a key component of visual communication in nature and acts particularly strongly in visual signalling by structurallycoloured animals during courtship. Two miniature peacock spiders (Maratus robinsoni and M. chrysomelas) court females using tiny structured scales (~ 40 × 10 μm2) that reflect the full visual spectrum. Using TEM and optical modelling, we show that the spiders’ scales have 2D nanogratings on microscale 3D convex surfaces with at least twice the resolving power of a conventional 2D diffraction grating of the same period. Whereas the long optical path lengths required …

Annotated World Bibliography Of Host Plants Of The Melon Fly, Bactrocera Cucurbitae (Coquillett) (Diptera: Tephritidae), Grant T. Mcquate, Nicanor J. Liquido, Kelly A. A. Nakamichi

Insecta Mundi

The melon fly, Bactrocera cucurbitae (Coquillett) (Diptera: Tephritidae), is a widespread, economically important tephritid fruit fly species. Bactrocera cucurbitae infests fruits and vegetables of a number of different plant species, with many host plants in the plant family Cucurbitaceae, but with additional hosts scattered across many other plant families. Although thought to be native to India, its distribution has spread throughout many countries in Oriental Asia, into a number of Pacific Island nations, and into Africa. The documented introductions into countries outside its native distribution show that this species could establish in other countries where it does not presently occur, …

Effects Of In-Situ Leaf-Level Canopy Warming In A Northern Hardwood Forest, Kelsey Carter Jan 2017

Effects Of In-Situ Leaf-Level Canopy Warming In A Northern Hardwood Forest, Kelsey Carter

Dissertations, Master's Theses and Master's Reports

Rising mean annual temperatures due to climate change have intensified the need to understand the effects of warming on plant physiological processes. Forest photosynthesis is the most important pathways of terrestrial carbon sequestration, yet continued warming could reduce this important carbon sink. Photosynthesis is highly sensitive to temperature and begins to decline after an optimum temperature (Topt) is reached, leading to reduced carbon uptake. To date, logistical difficulties have limited our ability to test photosynthetic responses to sustained warming in mature forest canopies. In order to understand how elevated temperatures will affect forest ecosystems, we need to be …

Human papillomaviruses (HPVs) are the most common sexually transmitted infections. Persistent infection with HPV can lead to anogenital cancers including head and neck cancers. Three prophylactic vaccines have been approved to prevent against some types of HPV infection. However, the vaccines are HPV-type specific and protect mostly against the HPV types included in the vaccines. To offer broader protection against more HPV types, studies in the field are developing candidate vaccines targeting a conserved minor capsid protein, L2. Nevertheless, reagents for developing and assessing L2 vaccines are limited. For example, antibodies to assess the antigenicity of some L2 epitopes are …

United States Department of Agriculture, Forest Service / University of Nebraska-Lincoln: Faculty Publications

In the Northeastern U.S., drought is expected to increase in frequency over the next century, and therefore, the responses of trees to drought are important to understand. There is recent debate about whether land-use change or moisture availability is the primary driver of changes in forest species composition in this region. Some argue that fire suppression from the early twentieth century to present has resulted in an increase in shade-tolerant and pyrophobic tree species that are drought intolerant, while others suggest precipitation variability as a major driver of species composition. From this debate, an emerging hypothesis is that mesophication and …
