The Role Of Natural Products In Pharmacotherapy Of Alzheimer’S Disease, Amrit Pal Singh
The Role Of Natural Products In Pharmacotherapy Of Alzheimer’S Disease, Amrit Pal Singh
Ethnobotanical Leaflets
Alzheimer’s disease is characterized by forgetfulness, disturbance in memory and loss of mental abilities. The final outcome of the disease is loss of personality and intellectual functions. Alzheimer’s disease is common cause of dementia particularly after the age of 70 years. Cholinesterase inhibitors are used for the treatment of Alzheimer’s dementia, but due to unpleasant side effect; these groups of drugs can not be used for long term treatment. Phyto drugs are being investigated for possible cure of Alzheimer’s disease. A number of constituents like Galanthamine, Huperzine, Hyperforin, & Desoxy-peganine have shown promising result. Some Ayurvedic herbs like Bacopa monneria …

Distribution, Habitat Partitioning, And Abundance Of Atlantic Spotted Dolphins, Bottlenose Dolphins, And Loggerhead Sea Turtles On The Eastern Gulf Of Mexico Continental Shelf, Robert B. Griffin, Nancy J. Griffin
Distribution, Habitat Partitioning, And Abundance Of Atlantic Spotted Dolphins, Bottlenose Dolphins, And Loggerhead Sea Turtles On The Eastern Gulf Of Mexico Continental Shelf, Robert B. Griffin, Nancy J. Griffin
Gulf of Mexico Science
We surveyed cetaceans and marine turtles from Nov. 1998 to Nov. 2000 along a series of prescribed transects between Tampa Bay and Charlotte Harbor, Florida, and between the coast and the 180-m isobath. Vertical profiles of temperature, salinity, and chlorophyll concentration were collected at 65 stations, and continuous surface data on these variables and transmittance were collected while underway. Habitat partitioning among Atlantic spotted dolphins (Stenella frontalis), bottlenose dolphins (Tursiops truncatus), and loggerhead sea turtles (Caretta caretta) was examined by canonical correspondence analyses of environmental characteristics at sighting locations. Environmental characteristics and primary productivity …
Evidence That Ultraviolet Radiation May Depress Short-Term Photosynthetic Rates Of Intertidal Ulva Lactuca And Consumption By A Generalist Feeder (Clibanarius Vittatus), Julien Lartigue, Frank M. Fontanella, Just Cebrian, Stanislaus Arbaczauskas
Evidence That Ultraviolet Radiation May Depress Short-Term Photosynthetic Rates Of Intertidal Ulva Lactuca And Consumption By A Generalist Feeder (Clibanarius Vittatus), Julien Lartigue, Frank M. Fontanella, Just Cebrian, Stanislaus Arbaczauskas
Gulf of Mexico Science
This article considers the impact of ultraviolet radiation (UVR) on the photosynthesis and consumption of intertidal Ulva lactuca, an important producer and food resource in many coastal ecosystems. Algal fragments were exposed in the laboratory to either UVR and PAR (photosynthetically active radiation) simultaneously or PAR alone. The rates of photosynthesis and consumption by a generalist feeder, the stripped hermit crab (Clibanarius vittatus), were then compared between the two treatments. In both experiments, the biological weighted values for UVR in the laboratory indicate that the experimental set-up provided a level of UVR exposure that would occur in …
Movements Of Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) In Nearshore Habitat As Determined By Acoustic Telemetry, Randy E. Edwards, Kenneth J. Sulak, Michael T. Randall, Churchill B. Grimes
Movements Of Gulf Sturgeon (Acipenser Oxyrinchus Desotoi) In Nearshore Habitat As Determined By Acoustic Telemetry, Randy E. Edwards, Kenneth J. Sulak, Michael T. Randall, Churchill B. Grimes
Gulf of Mexico Science
Gulf sturgeon were tagged with telemetry tags and were tracked and relocated in fall and early winter of 1996 and 1998 to determine migration patterns and winter feeding habitats after they emigrated from the Suwannee River, Florida, into the Gulf of Mexico. We hypothesized that their migration would generally follow the drowned Suwannee River channel across the West Florida shelf. Fish left the river in late Oct. or early Nov., about the time river water temperatures fell below 20 C. Tracked and relocated fish moved slowly and remained offshore of Suwannee Sound in nearby shallow (<6 m) marine-estuarine habitats until at least mid or late Dec. The relatively small area (~115km2) within which …
Meristic And Morphometric Differences In Populations Of Rivulus Marmoratus, D. Scott Taylor
Meristic And Morphometric Differences In Populations Of Rivulus Marmoratus, D. Scott Taylor
Gulf of Mexico Science
Rivulus marmoratus (Pisces: Aplocheilidae) is a small cyprinodontid found in mangroves of the western tropical Atlantic and is the only known self-fertilizing, hermaphroditic vertebrate. Populations normally consist of genetically diverse groups of homozygous clones. Rivulus marmoratus has the widest range of any member of the genus (southern Brazil to central Florida) and is the only marine representative of the genus. There has been considerable speculation about the "origin" of the species in an otherwise sexually reproducing genus and family. Although well studied in the laboratory, few specimens have been collected from the wild until recently. This study examined meristic and …

A Comparison Of Macroepifauna Among Vegetated And Unvegetated Habitats In A South Florida Estuary Using A Passive Sampling Gear, Paul J. Rudershausen, James V. Locascio, Lourdes M. Rojas
Gulf of Mexico Science
We compared abundance, richness, diversity, and community structure of macroepifauna among the seagrasses Halodule wrightii, Thalassia testudinum, and Syringodium filiforme, and unvegetated substrate in Tarpon Bay, Caloosahatchee River estuary, Florida. Sampling was conducted using wire-mesh minnow traps deployed over fifty-six 24-h periods from Jan. 1999 to Jan. 2000. A total of 36, 35, 28, and 28 species were identified from Halodule, Thalassia, Syringodium, and unvegetated samples, respectively. The gastropod Nassarius vibex was the most abundant species from Halodule and unvegetated substrate, whereas the pinfish (Lagodon rhomboides) was the most abundant species from …
Seasonal And Spatial Variation In Algal Composition And Biomass On The Central Florida Gulf Coast Shelf, Janessa Cobb, John M. Lawrence
Seasonal And Spatial Variation In Algal Composition And Biomass On The Central Florida Gulf Coast Shelf, Janessa Cobb, John M. Lawrence
Gulf of Mexico Science
Information on primary producers is fundamental to the understanding of communities. Little is known about the primary producers of marine communities at intermediate depths on the Florida Gulf Coast shelf. The diversity and biomass of algae and seagrass were studied seasonally at three offshore sites (12- to 18-m depth) and one nearshore site (6-m depth) on the central Florida Gulf Coast shelf. Thirty-eight species of attached and drift macroalgae and one drifting seagrass, Thalassia testudinum, were found. The deepest collection site was the most productive in terms of standing biomass and had much more flora on limestone rubble than …
The Effects Of Season And Proximity To Fringing Mangroves On Seagrass-Associated Fish Communities In Charlotte Harbor, Florida, Gregg R. Poulakis, David A. Blewett, Michael E. Mitchell
The Effects Of Season And Proximity To Fringing Mangroves On Seagrass-Associated Fish Communities In Charlotte Harbor, Florida, Gregg R. Poulakis, David A. Blewett, Michael E. Mitchell
Gulf of Mexico Science
Little has been published on habitat use by fishes in Charlotte Harbor, one of Florida's largest-and still relatively pristine-estuaries. Multivariate analyses of data from 21.3-m-seine samples (1996-2000) were used to examine spatiotemporal patterns of seagrass habitat use by Charlotte Harbor fishes. Two habitats (mangrove-associated seagrass shorelines and offshore seagrass flats) were examined. Throughout the year, the mangrove-seagrass habitat was distinguished by Menidia spp., Mugil gyrans, Eucinostomus harengulus, and Floridichthys carpio, and the offshore seagrass flats habitat was distinguished by Bairdiella chrysoura, Orthopristis chrysoptera, and Cynoscion nebulosus. The dry season (Dec.-May) was distinguished by Lagodon …

Dedicated Section: The Fifth International Seagrass Biology Workshop, 7-11 October 2002, Ensenada, Baja California, Mexico, Silvia E. Ibarra-Obando
Gulf of Mexico Science
Since 1996, seagrass experts have been meeting biennially to share knowledge of the biology of seagrasses and the animals associated with seagrass meadows. Previous workshops have taken place in Western Australia, Japan, the Philippines, and France. In 2002, the meeting was held in Mexico and four themes were chosen for the sessions: Ecophysiological Processes (Sven Beer, Chair), Plant-Animal Interactions (Kenneth L. HeckJR., Chair), Genetics and Reproductive Biology (Gabriele Procaccini and Michelle Wycott, Co-Chairs), and Changes in Seagrass Beds at the Local and Regional Scale (Fred T. Short, Chair). An additional session on Traditional Knowledge and Wisdom (Sandy Wyllie-Echeverria, Chair) provided …

Sizes And Shapes Of 10-Ma Distal Fall Pyroclasts In The Ogallala Ggroup, Nebraska, William I. Rose, C. M. Riley, S. Dartevelle
Department of Geological and Mining Engineering and Sciences Publications
Size distributions of distal ashfall particles from correlated 10-Ma layers in Nebraska, measured using laser diffraction methods, are lognormal with mode diameters of ∼90 mm. This ashfall is ∼100% bubble-wall shards of rhyolite glass and apparently represents a distal ashfall from an eruption 1400 km away. Measured terminal velocities of these ash particles are 0.2–18 cm/s, consistent with Stokes Law settling of spherical particles with diameters of 9–50 mm. Surface area of the ash particles, measured with gas adsorption, is 20–30 times the surface area of equivalent Stokes spheres. These results highlight the effects of shape and atmospheric drag in …
