Dr. Satchin Panda on Time-Restricted Feeding and Its Effects on Obesity, Muscle Mass & Heart Health
 
01:31:34
Dr. Rhonda Patrick speaks with Dr. Satchidananda Panda, a professor at the Salk Institute for Biological Studies in La Jolla, California. Satchin's work deals specifically with the timing of food and it's relationship with our biological clocks governed by circadian rhythm and also the circadian rhythm in general. ▶︎ Get the show notes! https://www.foundmyfitness.com/episodes/satchin-panda In this video we discuss... •The fascinating history of experimentation that ultimately elucidated the location for the region of the brain necessary for a properly timed sleep-wake cycles. • The relationship between our body's "master clock" and it's many peripheral clocks. • Why infants sleep so intermittently, instead of resting for a longer, sustained duration like healthy young adults... and why this sustained rest also goes haywire in the elderly. • The fascinating work Dr. Panda took part in that lead to the discovery of a specialized light receptor in the eye that sets circadian rhythms and is known as melanopsin. • The important relationship between the relatively light insensitive melanopsin, which requires around 1,000 lux of light to be fully activated, and its control of the circadian clock by means of activation of the suprachiasmatic nucleus and suppression of melatonin. • The effects light exposure seems to have on next-day cortisol, a glucocorticoid hormone that regulates around 10-20% of the human protein-encoding genome. • The clever experimental design by which Dr. Panda and his colleagues discovered that certain circadian rhythms, especially of the liver, are entrained by when we eat, instead of how much light we get. This underlines the fact that, when managing are circadian rhythm, both elements are important! • One of the more surprising effects of time-restricted feeding in mice eating a so-called healthy diet: increases in muscle mass and even endurance in some cases.

WELCOME TO TEACHING PATHSHALA!!!! TOPIC-Phenocopy |Penetrance |Pleiotropy | Conditional mutant |CSIR NET|Genetics basics Conditional mutant-Conditional mutation is a mutation that has wild-type phenotype under certain "permissive" environmental conditions and a mutant phenotype under certain "restrictive" conditions. Phenocopy-The phenotype that is not genetically controlled but looks like genetically controlled one is called phenocopy.it is an environmentally induced phenotype that resembles the phenotype determined by genotype. Penetrance-The extent to which a particular gene or set of genes is expressed in the phenotypes of individuals carrying it, measured by the proportion of carriers showing the characteristic phenotype. Pleiotropy-The term pleiotropy refers to the effect of a single gene on more than one character/trait. ******** ABOUT THIS CHANNEL ---This channel will have the syllabus wise lectures Video for CSIR-NET-Lifescience/GATE-Lifescience/BARC/ICMR-JRF/ICAR. ****** LIST OF IMPORTANT VIDEOS FOR CSIR NET EXAM- *****DEVELOPMENTAL BIOLOGY-CSIR NET***** Vulva for mation in C.elegans (P-1)- https://youtu.be/ati-iJ9zWKM Vulva for mation in C.elegans (P-2)- https://youtu.be/el2SUaJhS4o Eye Lens Induction- https://youtu.be/FgyTxSejfaQ Axis(A-P) formation in Drosophila- https://youtu.be/-EjT2Xe2O1A Axis(D-V) formation in Drosophila- https://youtu.be/IMqgpbBw1qM ****PLANT BIOLOGY-CSIR NET**** Agrobacterium transformation-https://youtu.be/9pj_SRs2z58 shoot apical meristem-https://youtu.be/Q8KIQSoUufU Stress physiology (part-1)- https://youtu.be/YoNgSOIsk0A Stress physiology (part-2)- https://youtu.be/BTh8THX3Bgo Stress physiology (part-3)- https://youtu.be/66pQplA3bCQ Stress physiology (part-4)- https://youtu.be/Rztffk3ZjCQ Phytochrome- https://youtu.be/AkRxzA6AbJI Cryptochrome- https://youtu.be/cOOnt_hicFU Phototropin- https://youtu.be/GHyrQx04aCU ABC model of flower- https://youtu.be/Opkmx8xnQ94 ****ECOLOGY UNIT-CSIR NET**** Top Down control- https://youtu.be/k_tvKHkfw2M Island Theory- https://youtu.be/kK3kNOzHxMs Niche and character displacement- https://youtu.be/el9HXUelTEs COMPETITIVE EXCLUSION PRINCIPLE- https://youtu.be/zV3LxYDz-qE THANK YOU!

Joseph Takahashi (UT Southwestern/HHMI) Part 1A: Circadian Clocks: Clock Genes, Cells and Circuits
 
33:18
https://www.ibiology.org/genetics-and-gene-regulation/circadian-clocks/ Lecture Overview: Circadian rhythms are an adaptation to the 24 hr day that we experience. Takahashi begins his talk with an historic overview of how the genes controlling circadian clocks were first identified in Drosophila and the cloning tour de force that was required to identify clock genes in mice. He also describes the experiments that resulted in the realization that all cells in the body have a circadian clock, not just cells in the brain. In part 1B, Takahashi explains that the suprachiasmatic nucleus (SCN) in the brain generates a circadian rhythm of fluctuating body temperature that, in turn, signals to peripheral tissues. Heat shock factor 1 is one of the signaling molecules responsible for communicating the temperature information and resetting peripheral clocks. In Part 2, Takahashi describes how crossing many mice of different genetic backgrounds allowed his lab to identify several genes that impact the output of the clock gene system through different mechanisms. Takahashi begins the last part of his presentation with the crystal structures of BMAL and Clock, the two central activators of clock gene transcription. He goes on to describe how his lab showed that BMAL/Clock controls the DNA binding activity of transcriptional regulators of not only cycling genes, but also of basic cell functions such as RNA polymerase 2 occupancy and histone modification. Speaker Bio: Joseph Takahashi received his BA in biology from Swarthmore College, his PhD in neuroscience from the University of Oregon, and he was a post-doctoral fellow with Martin Zatz at the National Institutes of Mental Health. He then spent 26 years at Northwestern University where he was a faculty member in the Department of Neurobiology and Physiology and in 1997 he became an Investigator of the Howard Hughes Medical Institute. In 2008, Takahashi joined the University of Texas, Southwestern Medical Center as the Loyd B. Sands Distinguished Chair in Neuroscience. Using forward genetic screens in mice, Takahashi identified the first mammalian circadian gene "Clock" in 1997. Since then, his lab has gone on to identify and clone numerous circadian genes in both the brain and tissues throughout the body. Takahashi has received numerous awards and honors for his ground-breaking research including election to the National Academy of Sciences.

Could an Animal See a Ghost?
 
04:46
We have all seen the videos of a dog or a cat interacting with what seems to be something we can not see. What is really happening? Is something there? Are these animals actually picking up on something that to us is invisible? It's common knowledge that dogs can smell things that humans can not. But a less discussed phenomenon is when dogs or cats are seeing things that we can not. Science has been probing at this for years and we still know very little. What we do know is that certain animal have a specific structure to their eyes that allows them to see Ultra Violet light. Animals can see magneticfields using what is called cryptochromes. Cryptochromes are a common group of light-sensitive molecules that exist in bacteria, plants, and animals. These specialized proteins enable certain animals, such as birds, insects, fish, and reptiles, to sense magnetic fields, allowing them to perceive direction, altitude, and location. It seems that many animals are able to see things humans can not. Many mammals can actually see they Ultra Violet light reflected from urine trails. With all of the evidence that animals are detecting things we can not we have to wonder what the animals are reacting to that remains unknown to us. In some cases the animals can even seem terrified. Let us know what you think these animals are seeing! https://twitter.com/TheInfoSquad https://www.facebook.com/TheInfoSquad http://cattime.com/cat-facts/lifestyle/2489-cats-can-see-things-that-are-invisible-to-humans http://www.petmd.com/news/health-science/what-cats-and-dogs-can-see-humans-cant-you-wont-believe-it-31380

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.

Monarch butterfly
 
30:49
The monarch butterfly (Danaus plexippus) is a milkweed butterfly (subfamily Danainae) in the family Nymphalidae. It may be the most familiar North American butterfly. Its wings feature an easily recognizable orange and black pattern, with a wingspan of 8.9–10.2 cm (3½–4 in). (The viceroy butterfly is similar in color and pattern, but is markedly smaller, and has an extra black stripe across the hind wing.) The eastern North American monarch population is notable for its southward late summer/autumn migration from the United States and southern Canada to Mexico, covering thousands of miles. The western North American population of monarchs west of the Rocky Mountains most often migrate to sites in California but have been found in overwintering Mexico sites.

Gene CRY1: The new study reveals that the mutation may be present in 1 in 75 people.
 
01:42
Gene CRY1: The new study reveals that the mutation may be present in 1 in 75 people.   If all life, which has been working better in the afternoon and evening, compared to mornings, a genetic mutation may be the cause. Researchers at Rockefeller University reported that a variant of the CRY1 gene slows down the functioning of the watch body called the circadian clock, which regulates the sleep-wake cycle. The report that people with Delayed Sleep Phase Disorder (DSPD) have a circadian cycle as do most others, causing them to stay awake at night. Compared with other mutations that have been linked to sleep disorders in single-individual families worldwide, this is a rather shocking genetic change, lead author Michael W. Young, Richard and Jeanne Fisher Professor and Director of the Laboratory Of Rockefeller Genetics. The new study reveals that the mutation can be present in up to 1 in 75 people in certain populations. The Centers for Disease Control and Prevention has estimated that between 50 and 70 million adults in the US Have DSPD-ranging from insomnia to narcolepsy-making them vulnerable to chronic diseases like diabetes, obesity and depression. DSPD interrupts the sleep-wake cycle and make the patients energetic for longer than other people. People who are often diagnosed with DSPD classify themselves as night lovers. Going to sleep late has its own drawbacks. Most people with DSPD have difficulty getting up early, going to school or working in time. Their bodies do not cooperate and are forced to wake up, which makes them feel tired and weak during the day, and leads to lack of sleep during the night. #People #sleep #body #DSPD #diagnosis #narcolepsy #Diseases #UnitedStates #Laboratory #mutation #populations #ymasciencia
