Corn: The Dynamic Genome
Plant genome research is already revolutionizing the field of biology. Currently, scientists are unlocking the secrets of some of the most important plants in our lives, including corn, cotton and potatoes. Secrets of Plant Genomes: Revealed! takes viewers on a lively, upbeat journey that explores how these plants got to be the way they are and investigates how we can make better use of them in the future. Plant scientists are hard at work--in the lab, in the field and at the computer--to increa
Aberrant mucin assembly in mice causes endoplasmic reticulum stress and spontaneous inflammation res
Background
MUC2 mucin produced by intestinal goblet cells is the major component of the intestinal mucus barrier. The inflammatory bowel disease ulcerative colitis is characterized by depleted goblet cells and a reduced mucus layer, but the aetiology remains obscure. In this study we used random mutagenesis to produce two murine models of inflammatory bowel disease, characterized the basis and nature of the inflammation in these mice, and compared the pathology with human ulcerative colitis.
ABCD's of MELANOMA
ABCD's of Melanoma.
Malignant Melanoma is the most aggressive of malignant cutaneous tumours. Cases with lymphonode involvement, and distant metastases, carry a very poor prognosis, (50% and 20% respectively alive in 5 years), while those presenting without evident lymphonode involvement have a much better survival rate (60% alive in 5 years).
It is therefore extremely important to do early malignant melanoma diagnosis. There are several criteria that may lead to the diagnosis of a malignant m
A semaphorin code defines subpopulations of spinal motor neurons during mouse development.
In the spinal cord, motor neurons (MNs) with similar muscle targets and sensory inputs are grouped together into motor pools. To date, relatively little is known about the molecular mechanisms that control the establishment of pool-specific circuitry. Semaphorins, a large family of secreted and cell surface proteins, are important mediators of developmental processes such as axon guidance and cell migration. Here, we used mRNA in situ hybridization to study the expression patterns of semaphorins

Symptoms of Posttraumatic Stress Disorder in a New Orleans Workforce Following Hurricane Katrina
On August 29, 2005, Hurricane Katrina made landfall resulting in catastrophic damage and flooding to New Orleans, LA, and the Gulf Coast, which may have had significant mental health effects on the population. To determine rates and predictors of symptoms consistent with a diagnosis of posttraumatic stress disorder (PTSD) in New Orleans residents following Hurricane Katrina, we conducted a web-based survey 6 months after Hurricane Katrina made landfall. Participants included 1,542 employees from
Attitudes Toward HIV Protease Inhibitors and Medication Adherence in an Inner City HIV Population
The objective of this pilot study was to examine attitudes toward protease inhibitors (PIs) among HIV-infected individuals and to assess the relationship between PI attitudes and adherence to PIs. Respondents were recruited from four AIDS service organizations in New York City; the total sample consisted of 97 HIV-infected individuals who were taking a PI. The sample consisted largely of African Americans and Latinos from inner city areas, and most had a low level of education. Adherence was sub
GeoMaths MathHelp Material
This site provides students with mathematics self-study material which is embedded within the context of the geosciences. The material consists of many MathHelp "notebooks" covering specific mathematical topics related to a relevant geological context, such as plate velocity or cliff erosion. The notebooks contain explanations, illustrations, and examples. A mathematical glossary is also constantly available, providing a brief explanation of mathematical keywords and links to the relevant notebo
The Study of Metals and Alloys by X-ray Powder Diffraction Methods
The object of this lesson is to introduce research students with no previous experience to the basic ideas of the use of the powder method for the study of metals and alloys.
1850?: Joseph Slocum, Portrait
This image is a portrait of Joseph Slocum, father of Margaret Olivia Slocum Sage. He is wearing a dark suit with a brocade waistcoat, a white shirt, and a dark cravat. His left hand rests inside his jacket, and his right arm is held away from his body, perhaps resting on a shelf or table.,This portrait shows the Hon. Joseph Slocum, Olivia's father. His career included, in addition to the business ventures documented here, one term as New York State Representative for his district -- a bribe, it
Fort Raleigh National Historic Site Teacher's Page
Roanoke Revisited supplements concepts in core curricula courses and provides teachers and their students with appropriate information for the study of pre-colonial America. Although each classroom teacher is likely to find multiple uses for the materials, the suggested method for implementation is through the use of peer-counseling techniques and experiential activities.
Cabrillo National Monument: Cabrillo as Classroom
This site describes several classroom resources about the monument near San Diego, CA. Featured is the Cabrillo Tidepool Study, a 4-week on-line unit designed for students at the 5th grade level. It covers many life science topics including ecosystems, adaptation, life-cycle, food web, and conservation, and it integrates language arts and math activities.
Bridging the Watershed
Bridging the Watershed (BTW) is an outreach program of the Alice Ferguson Foundation, in partnership with the National Park Service and area schools, whose purpose is to provide personally meaningful, educational experiences that connect students to their place in the natural and cultural world. BTW offers 5 core modules, as well as a host of park-specific curriculum units, that offer classroom lessons to prepare students for their field studies, guidance for data analysis after a field study,
Boston's Arnold Arboretum: A Place for Study and Recreation
provides readings, maps, and lesson ideas about the first arboretum in the U.S., which opened to the public in the 1880s. This site, though focused on a place devoted to the study of trees, can help students learn how 19th-century urban conditions influenced the development of parks and how to research the history of parks in their own communities.
Environmental Catalyst Module
In the Environmental Catalysis Module, a joint project with the Institute for Environmental Catalysis at Northwestern University, students learn what a catalyst is and become aware of the use of catalysis to promote environmental protection. Besides introducing the concept of catalysis, the module also focuses other issues such as catalytic selectivity, specificity, poisoning, condition optimization, and waste minimization. The first activity of the module introduces the concept of catalysis in
