Evaluation of Perennial Ryegrass Straw As a Forage Source for Ruminants
AN ABSTRACT OF THE THESIS OF Michael J. Fisher for the degree of Master of Science in Animal Sciencepresented on July 28, 2003. Title: Evaluation of Perennial Ryegrass Strawas a Forage Source for Ruminants. Redacted for Privacy Abstract approved: David W. Bohnert We conducted two experiments evaluating perennialryegrass straw as a forage source for ruminants. Experiment 1 evaluated digestion and physiological variables in steers offered perennial ryegrass straw containing increasing levels of lolitrem B. Sixteen ruminally cannulated Angus X Hereford steers (231 ± 2 kg BW)were blocked by weight and assigned randomly to one of four treatments (TRT). Steerswere provided perennial ryegrass straw at 120% of the previous 5-daverage intake. Prior to straw feeding, soybean meal (SBM) was provided (0.1% BW; CP basis) tomeet the estimated requirement for degradable intake protein. Low (L) and high(H) lolitrem B straws (<100 and 1550 ppb, respectively) were used to formulate TRT diets: LOW (100% L); LOW MIX (67% L:33% H); HIGH MIX (33% L:67% H); HIGH(100% H). Intake and digestibility of DM and OM, and ruminal pH, total VFA, andNH3-N were not affected by increasing lolitrem B concentration (P> 0.13). Ruminal indigestible ADF (IADF) fill increased linearly (P= 0.01) and JADF passage rate (%/h) decreased linearly (P = 0.04) as lolitrem B level increased. Experiment2 evaluated performance and production of 72 Angus X Herefordcows (539 ± 5 kg BW) consuming perennial ryegrass straw containing increasing levels of lolitremB during the last third of gestation. Cowswere blocked by body condition score (BCS) and randomly assigned to one of three TRT. -
Factors Influencing Pesticide Resistance in Psylla Pyricola Foerster and Susceptibility Inits Mirid
AN ABSTRACT OF THE THESIS OF: Hugo E. van de Baan for the degree ofDoctor of Philosopbv in Entomology presented on September 29, 181. Title: Factors Influencing Pesticide Resistance in Psylla pyricola Foerster and Susceptibility inits Mirid Predator, Deraeocoris brevis Knight. Redacted for Privacy Abstract approved: Factors influencing pesticide susceptibility and resistance were studied in Psylla pyricola Foerster, and its mirid predator, Deraeocoris brevis Knight in the Rogue River Valley, Oregon. Factors studied were at the biochemical, life history, and population ecology levels. Studies on detoxification enzymes showed that glutathione S-transferase and cytochrome P-450 monooxygenase activities were ca. 1.6-fold higherin susceptible R. brevis than in susceptible pear psylla, however, esterase activity was ca. 5-fold lower. Esterase activity was ca. 18-fold higher in resistant pear psylla than in susceptible D. brevis, however, glutathione S-transferase and cytochrome P-450 monooxygenase activities were similar. Esterases seem to be a major factor conferring insecticideresistance in P. Pvricola. Although the detoxification capacities of P. rivricola and D. brevis were quite similar, pear psylla has developed resistance to many insecticides in the Rogue River Valley, whereas D. brevis has remained susceptible. Biochemical factors may be important in determining the potential of resistance development, however, they are less important in determining the rate at which resistance develops. Computer simulation studies showed that life history and ecological factors are probably of greater importancein determining the rate at which resistance develops in P. pvricola and D. brevis. High fecundity and low immigration of susceptible individuals into selected populations appear to be major factors contributing to rapid resistance development in pear psylla compared with D. -

Musah Department of Chemistry, State University of New York at Albany, 1400 Washington Ave, Albany, NY, 12222, USA ARTICLE INFO ABSTRACT Keywords: Plants that produce atropine and scopolamine fall under several genera within the nightshade family. Both Hierarchical classification atropine and scopolamine are used clinically, but they are also important in a forensics context because they are Psychoactive plants abused recreationally for their psychoactive properties. The accurate species attribution of these plants, which Seed species identifiction are related taxonomically, and which all contain the same characteristic biomarkers, is a challenging problem in Metabolome profiling both forensics and horticulture, as the plants are not only mind-altering, but are also important in landscaping as Direct analysis in real time-mass spectrometry ornamentals. Ambient ionization mass spectrometry in combination with a hierarchical classification workflow Chemometrics is shown to enable species identification of these plants. The hierarchical classification simplifies the classifi- cation problem to primarily consider the subset of models that account for the hierarchy taxonomy, instead of having it be based on discrimination between species using a single flat classification model. Accordingly, the seeds of 24 nightshade plant species spanning 5 genera (i.e. Atropa, Brugmansia, Datura, Hyocyamus and Mandragora), were analyzed by direct analysis in real time-high resolution mass spectrometry (DART-HRMS) with minimal sample preparation required. -

Specifically, the petition concerns the 16 formation of hypochlorous acid at the anode of an electrolysis apparatus designed for its 17 production from a brine solution. This active ingredient is aqueous hypochlorous acid which acts 18 as an oxidizing agent. The petitioner plans use hypochlorous acid as a sanitizer and antimicrobial 19 agent for the production and handling of organic products. The petition also requests to resolve a 20 difference in interpretation of allowed substances for chlorine materials on the National List of 21 Allowed and Prohibited Substances that contain the active ingredient hypochlorous acid (NOP- 22 PM 14-3 Electrolyzed water). 23 The NOP has issued NOP 5026 “Guidance, the use of Chlorine Materials in Organic Production 24 and Handling.” This guidance document clarifies the use of chlorine materials in organic 25 production and handling to align the National List with the November, 1995 NOSB 26 recommendation on chlorine materials which read: 27 “Allowed for disinfecting and sanitizing food contact surfaces. -

INTRODUCTION The method was fully validated for the determination of aconitine from whole blood samples and applied in two cases of fatal poisoning. Plants of the genus Aconitum L (family of Ranunculaceae) are known to be among the most toxic plants of the Northern Hemisphere and are widespread across Europe, Northern Asia and North America. Two plants from this genus are of particular importance: the blue-blooded Aconitum napellus L.

Studies on the Most Traded Medicinal Plants from the Dolpa District of Nepal
View metadata, citation and similar papers at core.ac.uk brought to you by CORE provided by University of Toyama Repository STUDIES ON THE MOST TRADED MEDICINAL PLANTS FROM THE DOLPA DISTRICT OF NEPAL Mohan B. Gewali Division of Visiting Professors Institute of Natural Medicine University of Toyama Abstract The traditional uses, major chemical constituents and prominent biological activities of the most traded medicinal plants from Dolpa district of Nepal are described in this article. Cradled on the laps of the central Himalayan range, Nepal (147,181 Km2) is sandwiched between two Asian giants, India on the South and China on the North. Nepal is divided into 14 zones and 75 districts. The Karnali zone, which has a border with Tibet region of China, is made up of five districts. Dolpa district (7,889 km²) is one of them. Dolpa district’s topography starts from the subtropical region (1575 meter) and ends in the nival region (6883 meter) in the trans-Himalayan region. The district has a population of about 29545 with Hindu 60%, Buddhist 40% including 5.5% ancient Bonpo Religion. Major ethnic groups/castes belonging to both Hindu and Buddhist religions include Kshetri, Dangi, Rokaya, Shahi, Buda, Thakuri, Thakulla, Brahmins, Karki, Shrestha, Sherpa and other people of Tibetan origin. The languages spoken are Nepali, Dolpo and Kaike. Dolpo is a variant of the Tibetan language. Kaike is considered indigenous language of Tichurong valley. In the Dolpa district, the traditional Tibetan medical practices are common. The traditional Tibetan practitioners called the Amchis provide the health care service. The Amchis have profound knowledge about the medicinal herbs and the associated healing properties of the medicinal plants found in the Dolpa district. -
