Anorexia and digestibility decline in female lambs given 3,7,11-3h3-3-acetoxy-7, 15-dihydroxy-12, 13-epoxytrichothec-9-en-8-one(1996) Brewer, D.; Taylor, A.; McAlees, A.J.3,7,11-^3H3-3-Acetoxy-7,15-dihydroxy-12, 13-epoxytrichothec-9-en-8-one (I, R=H, R'=Ac) was produced by Fusarium culmorum(CMI14764) grown on a defined medium supplemented with 5-^3H2- mevalonic acid. The metabolite was rigorously purified and the position of the 3-^3H label unequivocally determined by tritylation of the 15-hydroxy group. hydrolysis of the ester and regiospecific oxidation of the 3-hydroxy group thus generated. The metabolite (I, R=H, R'=Ac) given as a single intraruminal dose (5 mg kg-^1) to female lambs resulted in a 44% decline in food intake and a 5%decrease in apparent digestibility of this feed, in the 4 days following administration of the toxin (I, R=H, R'=Ac).Item Open Access Studies on the phytoplankton and the water quality at Greenfield(1996) Devi, J. Sita; Lakshminarayana, J.S.S.A study of the phytoplankton of the Welsh Dee Estuary, a part of Liverpool Bay, is reported. Correlative studies of the phytoplankton and its biomass with those of the chemical parameters indicated relationships between periodicity of phytoplankton and water quality and the possible utilization of nutrients and some trace metals by the algae. The phytoplankton biomass judged by chlorophyll content ranged from 1.63 to 4.28 mg L-1. The species diversity of the phytoplankton varied from 2.33 to 3.98 characteristic of the oceanic plankton. The water quality was found to be within acceptable limits.Item Open Access Columella edentula (draparnaud, 1805) (pupillidae). A new addition to Nova Scotia’s terrestrial molusc fauna(1996) Luedey, R.; MacMillan, J.; Bartlett, C.Four specimens of Columella edentula (Drapamaud, 1805) (Mollusca: Pupillidae), a snail species previously unreported in Nova Scotia, were collected in July 1995 near Garbarus Bay. This extends the species range into Nova Scotia from the Magdalen Islands in the northwest, from Labrador in the north, and from the United States in the south.Item Open Access Charles Brenton Huggins Nobel Prize winner medicine 1996(1996) Burns, TerryHuggins won the 1966 Nobel prize in physiology for discoveries in hormonal treatment of prostatic cancer. He received the award as a co-recipient with Peyton Rous.
Huggins is a native of Halifax. Nova Scotia, Canada and his complete early- life history up to age 19 show he was Halifax grade schools. mostly in Halifax's south-end. He completed his high school in Parrsboro, Nova Scotia, the home of his mother.
After high school, he went to Acadia University (or his B.A., then to Harvard Medical School and he graduated in 1924. Dr. Huggins completed his formal education with a surgery fellowship in Michigan, the home of his wife, Emily Wellman, and finally a tour through Europe and Britain to look at some research in a number of fields. Huggins spent his entire medical research career at University of Chicago and between 1972·1979 he was the chancellor of his beloved alma mater in Nova Scotia, Acadia.<
Proclaiming Dr. Huggins achievements at the Nobel award ceremony, it was first noted that he had accomplished 'a new type of cancer treatment, one now assisting previously inaccessible patients with the use of nontoxic, natural hormones rather than toxic or radioactive agents with few side effects. In his address, Huggins said that the control of cancer by hormones can summarized: (1) some cancers differ essentially from the cells they arose in response from a change in the hormone environment; (2) certain cancers are harmone-dependent and these cells die when supporting hormones are removed; (3) certain cancers succumb when large amounts of hormones are administered.
Item Open Access Alexander Graham Bell’s optical disc and other inventions(1996) Hutt, DanThe latter part of the 19th century is known to historians as the Gilded Age of Invention. The flurry of inventions created by Alexander Graham Bell is characteristic of the period. when a handful of seemingly heroic individuals laid the groundwork for 20th century technology. While the technological and economic conditions were right for commercialization of the telephone, many of Bell's other ideas such as the optical disc recording faded into obscurity. Unlike his contemporary Thomas Edison, who strictly invented to exploit perceived market demand, Bell's activities were driven by the sometimes random forces of his curiosity. We discuss many of the creations of Nova Scotia's most illustrious resident inventor.
