PhotoFix: Photo-Oxidation vs. Glutaraldehyde Fixation
 
02:59
https://www.cryolife.com/products/photofix/ A short animation showing the difference between Photo-Oxidation vs. Glutaraldehyde Fixation. Unlike glutaraldehyde treated tissue, PhotoFix uses dye-mediated photo-oxidation to crosslink and stabilize the internal collagen structure, thereby, eliminating toxic by-products and making the tissue feel similar to autologous tissue. Indications for Use PhotoFix is indicated for the following uses: - Vascular repair and reconstruction - Carotid - Iliac - Femoral - Tibial blood vessels - Arteriovenous access revisions - Intracardiac repair - Great vessel repair - Suture line buttressing - Pericardial closure

Phototropism
 
08:39
Phototropism is the growth of organisms in response to a light stimulus. It is most often observed in plants, but can also occur in other organisms such as fungi. The cells on the plant that are farthest from the light have a chemical called auxin that reacts when phototropism occurs. This causes the plant to have elongated cells on the farthest side from the light. Phototropism is one of the many plant tropisms or movements which respond to external stimuli. Growth towards a light source is called positive phototropism, while growth away from light is called negative phototropism. Most plant shoots exhibit positive phototropism, and rearrange their chloroplasts in the leaves to maximize photosynthetic energy and promote growth. Roots usually exhibit negative phototropism, although gravitropism may play a larger role in root behavior and growth. Some vine shoot tips exhibit negative phototropism, which allows them to grow towards dark, solid objects and climb them. The combination of phototropism and gravitropism allow plants to grow in the correct direction. This video is targeted to blind users.

[Journal Club] Light-inducible protein-interaction modules based on Arabidopsis thaliana
 
13:36
Light inducible control of protein-protein interactions provides powerful optical tools for manipulating biological processes. General light-mediated modules have been discovered and engineered based on Arabidopsis thaliana, expecting to be useful for controlling a broad range of cell phenomena with high temporal and high spatial resolution. In this report, I introduced two representative light-mediated protein-protein interactions systems which are suitable for mammalian cells.

CIRCADIAN rhythm - WikiVidi Documentary
 
32:49
A circadian rhythm is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These 24-hour rhythms are driven by a circadian clock, and they have been widely observed in plants, animals, fungi, and cyanobacteria. The term circadian comes from the Latin circa, meaning "around" , and diēm, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Processes with 24-hour oscillations are more generally called diurnal rhythms; strictly speaking, they should not be called circadian rhythms unless their endogenous nature is confirmed. Although circadian rhythms are endogenous , they are adjusted to the local environment by external cues called zeitgebers , which include light, temperature and redox cycles. In medical science, an abnormal circadian rhythm in humans is known as circadian rhythm disorder. In 2017, the Nobel Prize in Physiology or Medicine was... http://www.wikividi.com ____________________________________ Shortcuts to chapters: 00:01:33: History 00:04:09: Origin 00:08:39: Importance in animals 00:09:18: Effect of circadian disruption 00:10:06: Effect of light–dark cycle 00:11:42: Arctic animals 00:12:56: Butterfly migration 00:13:16: In plants 00:17:36: Biological clock in mammals 00:19:47: Humans 00:20:46: Biological markers and effects 00:23:46: Outside the "master clock" 00:24:48: Light and the biological clock 00:25:15: Enforced longer cycles 00:26:09: Human health 00:27:11: Indoor lighting 00:27:43: Obesity and diabetes 00:28:43: Airline pilots (and cabin crew) 00:29:24: Disruption 00:30:36: Effect of drugs ____________________________________ Copyright WikiVidi.

Plant physiology
 
22:39
Plant physiology is a subdiscipline of botany concerned with the functioning, or physiology, of plants. Closely related fields include plant morphology (structure of plants), plant ecology (interactions with the environment), phytochemistry (biochemistry of plants), cell biology, genetics, biophysics and molecular biology. Fundamental processes such as photosynthesis, respiration, plant nutrition, plant hormone functions, tropisms, nastic movements, photoperiodism, photomorphogenesis, circadian rhythms, environmental stress physiology, seed germination, dormancy and stomata function and transpiration, both parts of plant water relations, are studied by plant physiologists.

Circadian rhythm
 
25:58
A circadian rhythm /sɜrˈkeɪdiən/ is any biological process that displays an endogenous, entrainable oscillation of about 24 hours. These rhythms are driven by a circadian clock, and rhythms have been widely observed in plants, animals, fungi, and cyanobacteria. The term circadian comes from the Latin circa, meaning "around" (or "approximately"), and diem or dies, meaning "day". The formal study of biological temporal rhythms, such as daily, tidal, weekly, seasonal, and annual rhythms, is called chronobiology. Although circadian rhythms are endogenous ("built-in", self-sustained), they are adjusted (entrained) to the local environment by external cues called zeitgebers, commonly the most important of which is daylight.

A. thaliana is considered a weed; it is found by roadsides and in disturbed land. A winter annual with a relatively short life cycle, A. thaliana is a popular model organism in plant biology and genetics. For a complex multicellular eukaryote, A. thaliana has a relatively small genome of approximately 135 megabase pairs (Mbp). It was the first plant to have its genome sequenced, and is a popular tool for understanding the molecular biology of many plant traits, including flower development and light sensing.

Elizabeth M. Middleton Maniac Lecture, March 28, 2018
 
50:43
Dr. Elizabeth M. Middleton, a senior terrestrial ecosystem and carbon cycle scientist at GSFC, presented a Maniac lecture entitled, "Four Satellites and a Cornfield." In this lecture, Betsy talks about her unconventional path as a woman scientist while balancing family and care-giver responsibilities. She recently claimed her 40 year NASA Certificate and Pin. During those four decades she has been fortunate to be directly involved in four satellite missions. These were Landsat (ERRSAC), EO-1 (Mission Scientist), an ESA mission (FLEX) now in formulation phase A, and a successful NASA mission concept development team (HyspIRI). In addition, she has been involved in basic research on plant physiology and reflectance characteristics. Various in situ studies include hyperspectral and BRDF properties of plant canopies, UV-B effects on soybean, and nitrogen and drought effects on photosynthesis and fluorescence in cornfields. She was also a PI and Co-PI in the FIFE and BOREAS multi-year field campaigns.
