Ethnobotanical Study Of Galliyat For Botanical Demography And Bioecological Diversification, Muhammad Arshad, Mushtaq Ahmad
Ethnobotanical Leaflets
The present research work was based on the results of an enthnobotanical research project conducted in the Galliyat areas of NWFP, Province (Pakistan) during July 2003-March 2004. The region is mountainous with pine forests. Botanists have rarely studied the remote villages of the area, hence ethnobotanical information is quite meager. The local people of the area have always used surrounding natural resources that is wild plants for medicinal purposes and have for a long time dependent on the surrounding plant sources for their food, shelter, fodder, timber, fuel and health care. The present study mainly focus on the information regarding …

Ethnophytotherapical Approaches For The Treatment Of Diabetes By The Local Inhabitants Of District Attock (Pakistan), Mushtaq Ahmad, Mir Ajab Khan, Muhammad Arshad, Muhammad Zafar
Ethnobotanical Leaflets
Results of the present investigation are based on 37 indigenous plant species belonging to 23 Angiospermic families. These indigenous plants were used as traditional phytotherapies for the control and treatment of diabetes millitus. The rural inhabitants of the area classified these traditional phytotherapies on the basis of uses of various parts of plants and method of their uses. About 29 traditional phytotherapies were investigated from the rural inhabitants of the area. These traditional phytotherapies were classified as antidiabetic extracts, leaves, powders, flour, seeds, vegetables, fruits and herbal mixtures.

Red Light Regulation Of Ethylene Biosynthesis And Gravitropism In Etiolated Pea Stems, C. L. Steed, L. K. Taylor, Marcia Harrison-Pitaniello Phd
Red Light Regulation Of Ethylene Biosynthesis And Gravitropism In Etiolated Pea Stems, C. L. Steed, L. K. Taylor, Marcia Harrison-Pitaniello Phd
Biological Sciences Faculty Research
During gravitropism, the accumulation of auxin in the lower side of the stem causes increased growth and the subsequent curvature, while the gaseous hormone ethylene plays a modulating role in regulating the kinetics of growth asymmetries. Light also contributes to the control of gravitropic curvature, potentially through its interaction with ethylene biosynthesis. In this study, red-light pulse treatment of etiolated pea epicotyls was evaluated for its effect on ethylene biosynthesis during gravitropic curvature. Ethylene biosynthesis analysis included measurements of ethylene; the ethylene precursor 1-aminocyclopropane-1-carboxylic acid (ACC); malonyl-conjugated ACC (MACC); and expression levels of pea ACC oxidase (Ps-ACO1) and …
Acoustic Sensing For Ocean Research, Bruce M. Howe, James H. Miller
Acoustic Sensing For Ocean Research, Bruce M. Howe, James H. Miller
Ocean Engineering Faculty Publications
Ocean observatories have the potential to examine the physical, chemical, biological, and geological parameters and processes of the ocean at time and space scales previously unexplored. Acoustics provides an efficient and cost-effective means by which these parameters and processes can be measured and information can be communicated. Integrated acoustics systems providing navigation and communications and conducting acoustic measurements in support of science applications are, in concept, analogous to the Global Positioning System, but rely on acoustics because the ocean is opaque to electromagnetic waves and transparent to sound. A series of nested systems is envisioned, from small- to regional- to …

Porphyrin Depth In Lipid Bilayers As Determined By Iodide And Parallax Fluorescence Quenching Methods And Its Effect On Photosensitizing Efficiency, Irena Bronshtein, Michal Afri, Hana Weitman, Aryeh A. Frimer, Kevin M. Smith, Benjamin Ehrenberg
Porphyrin Depth In Lipid Bilayers As Determined By Iodide And Parallax Fluorescence Quenching Methods And Its Effect On Photosensitizing Efficiency, Irena Bronshtein, Michal Afri, Hana Weitman, Aryeh A. Frimer, Kevin M. Smith, Benjamin Ehrenberg
Faculty Publications
Photosensitization by porphyrins and other tetrapyrrole chromophores is used in biology and medicine to kill cells. This light-triggered generation of singlet oxygen is used to eradicate cancer cells in a process dubbed "photodynamic therapy," or PDT. Most photosensitizers are of amphiphilic character and they partition into cellular lipid membranes. The photodamage that they inflict to the host cell is mainly localized in membrane proteins. This photosensitized damage must occur in competition with the rapid diffusion of singlet oxygen through the lipid phase and its escape into the aqueous phase. In this article we show that the extent of damage can …
Separation Of Benzodiazepines Using Capillary Electrochromatography, Constantina P. Kapnissi, Isiah M. Warner
Separation Of Benzodiazepines Using Capillary Electrochromatography, Constantina P. Kapnissi, Isiah M. Warner
Faculty Publications
Benzodiazepines are often used for the treatment of epilepsy, convulsions, and many psychiatric disorders. The widespread use of this class of drugs has occasionally raised concern about recreational benzodiazepine abuse and has led to the erroneous impression that benzodiazepines have a relatively high abuse liability among recreational drug users. Therefore, the separation and identification of these compounds is of great interest. In general, the separation of benzodiazepines is performed using high-performance liquid chromatography (HPLC). Recently, capillary electrochromatography, which combines the high efficiency of capillary zone electrophoresis and the high selectivity of HPLC, has gained much attention. The focus of the …

Impaired Coordination Of Nutrient Intake And Substrate Oxidation In Melanocortin-4 Receptor Knockout Mice, Diana C. Albarado, Jennifer Mcclaine, Jacqueline M. Stephens, Randall L. Mynatt, Jianping Ye, Anthony W. Bannon, William G. Richards, Andrew A. Butler
Faculty Publications
Mutations in the melanocortin-4 receptor (MC4R) are associated with obesity. The obesity syndrome observed in humans with MC4R haploinsufficiency is similar to that observed in MC4R knockout mice: increased longitudinal growth, hyperphagia, and fasting hyperinsulinemia. For comparison with other commonly investigated models of obesity and insulin resistance, we have backcrossed Mc4r-/- mice into the C57BL/6J (B6) background. Female obese Mc4r-/- mice exhibit reduced energy expenditure and an attenuated increase in fatty acid oxidation following exposure to high fat diets compared to obese Lep ob/Lepob mice. The reduced energy expenditure and fatty acid oxidation correlates with changes in hepatic gene expression. …
High-Latitude Tertiary Migrations Of An Exclusively Tropical Clade: Evidence From Malpighiaceae, Charles C. Davis, Peter W. Fritsch, Charles D. Bell, Sarah Mathews
High-Latitude Tertiary Migrations Of An Exclusively Tropical Clade: Evidence From Malpighiaceae, Charles C. Davis, Peter W. Fritsch, Charles D. Bell, Sarah Mathews
Faculty Publications
Explanations of tropical intercontinental disjunctions involving South America and Africa typically invoke vicariance of western Gondwanan biotas or long-distance dispersal. However, many plant groups originated and diversified well after the last direct connection between Africa and South America (ca. 105 million years before the present [mybp]), and it is unlikely that long-distance dispersal accounts for the distribution of all of these. A less commonly invoked explanation, the boreotropics hypothesis, indicates that some tropical disjunctions arose during the Tertiary via high-latitude land connections when northern forests supported tropical vegetation. Malpighiaceae are widely distributed across Africa and South America and have been …

Variation In Small Sapling Density, Understory Cover, And Resource Availability In Four Neotropical Forests, Kyle E. Harms, Jennifer S. Powers, Rebecca A. Montgomery
Faculty Publications
Even though many forest plants spend all or a significant portion of their lives in the forest understoty, few studies have compared understory composition, structure, and resource availability among forests. We used standardized transect-based methods to compare small sapling densities (10-50 cm tall), understory vegetation cover, canopy openness, and nutrient availability in non-gap portions of four lowland Neotropical forests: La Selva, Costa Rica (LS), Barro Colorado Island, Panama (BCI), Cocha Cashu, Peru (CC), and north of Manaus, Brazil (KM41). Sites differed significantly in all variables except canopy openness. LS had high palm and non-fern herb cover and low density of …
Response Of A Gall-Forming Guild (Hymenoptera: Cynipidae) To Stressed And Vigorous Prairie Roses, Mark A. Williams, James T. Cronin
Response Of A Gall-Forming Guild (Hymenoptera: Cynipidae) To Stressed And Vigorous Prairie Roses, Mark A. Williams, James T. Cronin
Faculty Publications
Two general hypotheses that describe the relationship between plant quality and host-plant preference of insect herbivores are the plant-stress and plant-vigor hypotheses. We examined the response of a gall-forming guild of insect herbivores associated with prairie rose, Rosa arkansana Porter (Rosaceae), to experimental manipulations of plant stress (addition of NaCl) and vigor (addition of nitrogen; NH4NO3). The most common members of the gall-forming guild on roses are Diplolepis ignota Osten Sacken, D. nodulosa Beutenmüller, and D. rosaefolii Cockerell (Hymenoptera: Cynipidae). The repeated application of nitrogen throughout the growing season to prairie plots resulted in significantly higher plant nitrogen levels and …
The Matrix Enhances The Effectiveness Of Corridors And Stepping Stones, Kristen A. Baum, Kyle J. Haynes, Forrest P. Dillemuth, James T. Cronin
The Matrix Enhances The Effectiveness Of Corridors And Stepping Stones, Kristen A. Baum, Kyle J. Haynes, Forrest P. Dillemuth, James T. Cronin
Faculty Publications
Conservation strategies often call for the utilization of corridors and/or stepping stones to promote dispersal among fragmented populations. However, the extent to which these strategies increase connectivity for an organism may depend not only on the corridors and stepping stones themselves, but also on the composition of the surrounding matrix. Using an herbivore-host-plant system consisting of the planthopper Prokelisia crocea and its sole host plant, prairie cordgrass (Spartina pectinata), we show that the effectiveness of corridors and stepping stones for promoting planthopper dispersal among patches depended strongly on the intervening matrix habitat. In a low-resistance matrix (one that facilitates high …

A Genome Scan Among Nigerians Linking Resting Energy Expenditure To Chromosome 16, Xiaodong Wu, Amy Luke, Richard S. Cooper, Xiaofeng Zhu, Donghui Kan, Bamidele O. Tayo, Adebowale Adeyemo
Faculty Publications
Energy requirements at rest account for 50% to 75% of total energy expenditure. Interindividual variation in resting energy expenditure (REE) has been studied for potential links to obesity and hypertension. REE is a modestly heritable trait, and yet virtually nothing is known about the genetic factors that might influence the familial patterns. The objectives of this study were to identify the genomic regions showing genetic linkage to REE variation in a Nigerian population. For linkage analysis across the genome, three hundred seventy-seven microsatellite markers were typed on DNA from 995 individuals in 153 families. A genome scan was performed using …

Chromosome 2 has been consistently identified as a genomic region with genetic linkage evidence suggesting that one or more loci contributes to blood pressure and hypertension status. As with all complex disease traits, following-up linkage evidence to identify the underlying susceptibility gene(s) is an arduous yet biologically and clinically important task. Using combined positional candidate gene methods, the Family Blood Pressure Program (FBPP) has concentrated efforts in narrowing a large region of chromosome 2, demonstrating evidence for linkage in several populations, and identifying underlying candidate hypertension susceptibility gene(s). Initial informatics efforts identified the boundaries of the region and the known …

Influence Of Drought Stress On Sweetpotato Resistance To Sweetpotato Weevil, Cylas Formicarius (Coleoptera: Apoinidae), And Storage Root Chemistry, Lixin Mao, Louis E. Jett, Richard N. Story, Abner M. Hammond, Joseph K. Peterson, Don R. Labonte
Faculty Publications
The effect of drought stress on the resistance of sweetpotato roots to sweetpotato weevil (SPW), Cylas formicarius (Fab.), was studied in 1997 and 1998 in two genotypes ("Beauregard" and "Excel") with different SPW susceptibility. Storage roots produced under drought or normal conditions were tested for adult feeding, oviposition, larval survival and pupal weight in the laboratory under no-choice and free-choice test conditions. The levels of sweetpotato resin glycoside and caffeic acid in the periderm tissue of the roots were also determined. Drought-stressed roots received significantly more SPW eggs under no-choice and free-choice conditions and more feeding punctures under free-choice conditions …

Host plant-mediated orientation and oviposition by diamondback moth (DBM) Plutella xylostella (L.) (Lepidoptera: Yponomeutidae) and its predator Chrysoperla carnea Stephens (Neuroptera: Chrysopidae) were studied in response to four different brassica host plants: cabbage, (Brassica oleracea L. subsp. capitata), cauliflower (B. oleracea L. subsp. botrytis), kohlrabi (B. oleracea L. subsp. gongylodes), and broccoli (B. oleracea L. subsp. italica). Results from laboratory wind tunnel studies indicated that orientation of female DBM and C. carnea females towards cabbage and cauliflower was significantly greater than towards either broccoli or kohlrabi plants. However, DBM and C. carnea males did not orient towards any of the …

Several plant species defend themselves indirectly from herbivores by producing herbivore-induced volatile compounds that attract the natural enemies of herbivores. Here we tested the effects of elevated atmospheric CO2 (720 μmol mol-1) concentration on this indirect defense, physiological properties, and constitutive and induced emissions of white cabbage (Brassica oleracea ssp. capitata, cvs Lennox and Rinda). We monitored the orientation behavior of the generalist predator Podisus maculiventris (Heteroptera: Pentatomidae) and the specialist parasitoid Cotesia plutellae (Hymenoptera: Braconidae) to plants damaged by Plutella xylostella (Lepidoptera: Plutellidae) in the Y-tube olfactometer. Elevated CO2 levels did not affect stomatal densities but reduced specific leaf …

Although several reports underscore the importance of silicon (Si) in controlling Magnaporthe grisea on rice, no study has associated this beneficial effect with specific mechanisms of host defense responses against this fungal attack. In this study, however, we provide evidence that higher levels of momilactone phytoalexins were found in leaf extracts from plants inoculated with M. grisea and amended with silicon (Si+) than in leaf extracts from inoculated plants not amended with silicon (Si-) or noninoculated Si+ and Si- plants. On this basis, the more efficient stimulation of the terpenoid pathway in Si+ plants and, consequently, the increase in the …

Beet armyworm, Spodoptera exigua (Hübner), and fall armyworm, Spodoptera frugiperda (J. E. Smith), are occasional pests of cotton, Gossypium hirsutum (L.), and soybean, Glycine max (L.) Merrill. These insects can be difficult to control due to insecticide resistance and larval behavior on plants. The objectives of these studies were to determine the efficacy of selected insecticides against native infestations of beet armyworm in cotton and soybean and to generate baseline dose-mortality responses for beet armyworm and fall armyworm adults to indoxacarb and pyridalyl in the adult vial test. Indoxacarb, pyridalyl, spinosad, methoxyfenozide, and emamectin benzoate controlled beet armyworm infestations up …

The impact of brown stink bug, Euschistus servus (Say), and southern green stink bug, Nezara viridula (L.), injury was evaluated on preflowering and flowering cotton, Gossypium hirsutum L., plants in no-choice tests. Vegetative stage cotton seedlings and reproductive structures, including flower buds (square) and bolls, were infested with adults and/or nymphs of both species. There were no significant differences in height, height to node ratio, square retention, and flower initiation for cotton seedlings or plants with a match-head square between southern green stink bug adult- or brown stink bug adult-infested and noninfested treatments. Abscission for individual large squares (precandle) and …
Is Anyone To Blame For Pollution?, Aaron Lercher
Is Anyone To Blame For Pollution?, Aaron Lercher
Faculty Publications
By making use of a distinction between "making something happen" and "allowing it to happen," a polluting act can be defined as making something happen with widely scattered externalized costs. Not all polluting acts are blameworthy, but we can investigate which polluting acts are sufficiently badly performed as to be blameworthy. This definition of polluting act permits us to justify the belief we often have that behavior concerning pollution may be blameworthy, even when we do not know whether the behavior caused harm.

We sequenced two regions of the mitochondrial genome, ND4 and d-loop, from 64 Eumeces septentrionales to assess intra- and interspecific population differentiation. We constructed haplotype genealogies for nine Eumeces septentrionalis septentrionalis populations in previously glaciated regions and used nested clade analysis to examine the role of vicariance and dispersal in shaping the population structure of E. s. septentrionalis in the northern part of its range following Pleistocene paleoclimatological events. In addition, we used DNA sequence data to compare populations of the northern subspecies (E. s. septentrionalis) with the southern subspecies (Eumeces septentrionalis obtusirostris) to determine whether specific level differentiation is …

Faculty Publications
The Alu Yb-lineage is a 'young' primarily human-specific group of short interspersed element (SINE) subfamilies that have integrated throughout the human genome. In this study, we have computationally screened the draft sequence of the human genome for Alu Yb-lineage subfamily members present on autosomal chromosomes. A total of 1,733 Yb Alu subfamily members have integrated into human autosomes. The average ages of Yb-lineage subfamilies, Yb7, Yb8 and Yb9, are estimated as 4.81, 2.39 and 2.32 million years, respectively. In order to determine the contribution of the Alu Yb-lineage to human genomic diversity, 1,202 loci were analysed using polymerase chain reaction …
