Early Spring and Autumn in Cowles Bog

submitted by: chris.g.meyer
This film is meant to both highlight the value of conservation and to inspire fascination and curiosity with Nature. This is achieved by briefly contrasting the industrialized southern lakeshore of Lake Michigan with two nearby national parks (Cowles Bog National Natural Landmark and the Indiana Dunes National Lakeshore) and by exhibiting the beauty and diversity of the parks in two hikes recorded in Autumn 2007 and Spring 2008. The hikes begin in Cowles Bog and follow a trail out to the...

WERNER SYNDROME

submitted by: camdic
German physician Otto Werner (1879-1936) described the clinical picture of this syndrome in 1904, in four sisters, defining the skin thin, tight, scleroderma-like, that mimics premature aging, with bilateral cataracts associated. Also known with the term Progeria, "Prematurely Old" greek derivation, due to the fact that usually presents wrinkling and aging of face. Progeria occurs in two forms: Progeria of childhood, described by Jonathan Hutchinson (1886) and Hastings Gilford (1897),...

XERODERMA PIGMENTOSUM

submitted by: camdic
Hereditary disease, trasmitted with recessive autosomical modality, the XP is characterized from extreme photosensivity, that causes strict and premature damages to level of the cutis and of the eyes. Its incidence is of 1: 250 thousand in Europe and USA, while in Japan the relationship is of 1:40 thousand. In the child affected by XP, also short exposure to the sun's ultraviolet rays, determines severe cutaneous sunburn with slow resolution, therefore it is from avoiding sources of...

Atoms to X-rays: How Do Proteins Fold? Theory Meets Experiments

submitted by: video_collector
The machinery of life depends on proteins--large organic molecules composed of tens, hundreds or even thousands of amino acids bound together and folded into specifically shaped structures. How they fold into these three-dimensional structures is known as the second genetic code and is one of great challenges in science today. Join UCSD biophysicist Jose Onuchic, as he explores how physics, chemistry, biology and mathematics are all being applied to crack the protein folding mystery. Series:...

Trudy Forte presents "Drugs for Brain Tumors"

submitted by: video_collector

Trudy Forte discusses her work developing nano-sized low-density lipoprotein (LDL) particles that can be used as a safe and effective means of delivering anticancer drugs to brain tumors, particularly the most common malignant brain tumor in adults and one of the deadliest forms of cancer.

Lung Cancer Risks raised by Genetic Variations

submitted by: mdanderson

A research team led by scientists at MD Anderson Cancer Center report that 2 specific common inherited
genetic variations are associated with increased risk of lung cancer for smokers and former smokers.
Dr. Amos talks about how the findings are a major step forward in identifying those at high risk for
non-small cell lung cancer and for understanding how smoking and genetic factors interact to cause the disease.
