The document discusses Lemuria, a hypothetical lost land located in the Indian and Pacific Oceans that was proposed in the 19th century to explain discontinuities in biogeography. While sunken continents do exist, there is no geological evidence that corresponds to Lemuria. Some later associated Lemuria with Kumari Kandam, a legendary sunken land mentioned in Tamil literature. Tamil nationalists proposed that Kumari Kandam, now identified with Lemuria, was the cradle of civilization and the origin of all human languages and Tamil in particular. However, modern plate tectonics have rendered the concept of a sunken Lemuria obsolete.

Have a passion for history? Love French literature? Intrigued by Psychology? All of these subjects can make great college majors. College isn't necessarily about preparing you for a single future job. It's about learning how to learn, how to think, how to express yourself articulately, how to be collaborative, and how to succeed under pressure. Studying something you love or are at least interested in will likely be more valuable long-term than a “practical” degree you don’t engage with. This short presentation will walk you through the pros of a Liberal Arts education in the 21st Century marketplace and illustrate why an English Degree with Honors is worth more than a C-average Business degree.

Cancer cell metabolism: special Reference to Lactate PathwayAADYARAJPANDEY1
Normal Cell Metabolism:
Cellular respiration describes the series of steps that cells use to break down sugar and other chemicals to get the energy we need to function.
Energy is stored in the bonds of glucose and when glucose is broken down, much of that energy is released.
Cell utilize energy in the form of ATP.
The first step of respiration is called glycolysis. In a series of steps, glycolysis breaks glucose into two smaller molecules - a chemical called pyruvate. A small amount of ATP is formed during this process.
Most healthy cells continue the breakdown in a second process, called the Kreb's cycle. The Kreb's cycle allows cells to “burn” the pyruvates made in glycolysis to get more ATP.
The last step in the breakdown of glucose is called oxidative phosphorylation (Ox-Phos).
It takes place in specialized cell structures called mitochondria. This process produces a large amount of ATP. Importantly, cells need oxygen to complete oxidative phosphorylation.
If a cell completes only glycolysis, only 2 molecules of ATP are made per glucose. However, if the cell completes the entire respiration process (glycolysis - Kreb's - oxidative phosphorylation), about 36 molecules of ATP are created, giving it much more energy to use.
IN CANCER CELL:
Unlike healthy cells that "burn" the entire molecule of sugar to capture a large amount of energy as ATP, cancer cells are wasteful.
Cancer cells only partially break down sugar molecules. They overuse the first step of respiration, glycolysis. They frequently do not complete the second step, oxidative phosphorylation.
This results in only 2 molecules of ATP per each glucose molecule instead of the 36 or so ATPs healthy cells gain. As a result, cancer cells need to use a lot more sugar molecules to get enough energy to survive.

introduction to WARBERG PHENOMENA:
WARBURG EFFECT Usually, cancer cells are highly glycolytic (glucose addiction) and take up more glucose than do normal cells from outside.
Otto Heinrich Warburg (; 8 October 1883 – 1 August 1970) In 1931 was awarded the Nobel Prize in Physiology for his "discovery of the nature and mode of action of the respiratory enzyme.
WARNBURG EFFECT : cancer cells under aerobic (well-oxygenated) conditions to metabolize glucose to lactate (aerobic glycolysis) is known as the Warburg effect. Warburg made the observation that tumor slices consume glucose and secrete lactate at a higher rate than normal tissues.
Introduction:
RNA interference (RNAi) or Post-Transcriptional Gene Silencing (PTGS) is an important biological process for modulating eukaryotic gene expression.
It is highly conserved process of posttranscriptional gene silencing by which double stranded RNA (dsRNA) causes sequence-specific degradation of mRNA sequences.
dsRNA-induced gene silencing (RNAi) is reported in a wide range of eukaryotes ranging from worms, insects, mammals and plants.
This process mediates resistance to both endogenous parasitic and exogenous pathogenic nucleic acids, and regulates the expression of protein-coding genes.
What are small ncRNAs?
micro RNA (miRNA)
short interfering RNA (siRNA)
Properties of small non-coding RNA:
Involved in silencing mRNA transcripts.
Called “small” because they are usually only about 21-24 nucleotides long.
Synthesized by first cutting up longer precursor sequences (like the 61nt one that Lee discovered).
Silence an mRNA by base pairing with some sequence on the mRNA.
Discovery of siRNA?
The first small RNA:
In 1993 Rosalind Lee (Victor Ambros lab) was studying a non- coding gene in C. elegans, lin-4, that was involved in silencing of another gene, lin-14, at the appropriate time in the
development of the worm C. elegans.
Two small transcripts of lin-4 (22nt and 61nt) were found to be complementary to a sequence in the 3' UTR of lin-14.
Because lin-4 encoded no protein, she deduced that it must be these transcripts that are causing the silencing by RNA-RNA interactions.
Types of RNAi ( non coding RNA)
MiRNA
Length (23-25 nt)
Trans acting
Binds with target MRNA in mismatch
Translation inhibition
Si RNA
Length 21 nt.
Cis acting
Bind with target Mrna in perfect complementary sequence
Piwi-RNA
Length ; 25 to 36 nt.
Expressed in Germ Cells
Regulates trnasposomes activity
MECHANISM OF RNAI:
First the double-stranded RNA teams up with a protein complex named Dicer, which cuts the long RNA into short pieces.
Then another protein complex called RISC (RNA-induced silencing complex) discards one of the two RNA strands.
The RISC-docked, single-stranded RNA then pairs with the homologous mRNA and destroys it.
THE RISC COMPLEX:
RISC is large(>500kD) RNA multi- protein Binding complex which triggers MRNA degradation in response to MRNA
Unwinding of double stranded Si RNA by ATP independent Helicase
Active component of RISC is Ago proteins( ENDONUCLEASE) which cleave target MRNA.
DICER: endonuclease (RNase Family III)
Argonaute: Central Component of the RNA-Induced Silencing Complex (RISC)
One strand of the dsRNA produced by Dicer is retained in the RISC complex in association with Argonaute
ARGONAUTE PROTEIN :
1.PAZ(PIWI/Argonaute/ Zwille)- Recognition of target MRNA
2.PIWI (p-element induced wimpy Testis)- breaks Phosphodiester bond of mRNA.)RNAse H activity.
MiRNA:
The Double-stranded RNAs are naturally produced in eukaryotic cells during development, and they have a key role in regulating gene expression .
(May 29th, 2024) Advancements in Intravital Microscopy- Insights for Preclini...Scintica Instrumentation
Intravital microscopy (IVM) is a powerful tool utilized to study cellular behavior over time and space in vivo. Much of our understanding of cell biology has been accomplished using various in vitro and ex vivo methods; however, these studies do not necessarily reflect the natural dynamics of biological processes. Unlike traditional cell culture or fixed tissue imaging, IVM allows for the ultra-fast high-resolution imaging of cellular processes over time and space and were studied in its natural environment. Real-time visualization of biological processes in the context of an intact organism helps maintain physiological relevance and provide insights into the progression of disease, response to treatments or developmental processes.
In this webinar we give an overview of advanced applications of the IVM system in preclinical research. IVIM technology is a provider of all-in-one intravital microscopy systems and solutions optimized for in vivo imaging of live animal models at sub-micron resolution. The system’s unique features and user-friendly software enables researchers to probe fast dynamic biological processes such as immune cell tracking, cell-cell interaction as well as vascularization and tumor metastasis with exceptional detail. This webinar will also give an overview of IVM being utilized in drug development, offering a view into the intricate interaction between drugs/nanoparticles and tissues in vivo and allows for the evaluation of therapeutic intervention in a variety of tissues and organs. This interdisciplinary collaboration continues to drive the advancements of novel therapeutic strategies.
A brief information about the SCOP protein database used in bioinformatics.
The Structural Classification of Proteins (SCOP) database is a comprehensive and authoritative resource for the structural and evolutionary relationships of proteins. It provides a detailed and curated classification of protein structures, grouping them into families, superfamilies, and folds based on their structural and sequence similarities.
The increased availability of biomedical data, particularly in the public domain, offers the opportunity to better understand human health and to develop effective therapeutics for a wide range of unmet medical needs. However, data scientists remain stymied by the fact that data remain hard to find and to productively reuse because data and their metadata i) are wholly inaccessible, ii) are in non-standard or incompatible representations, iii) do not conform to community standards, and iv) have unclear or highly restricted terms and conditions that preclude legitimate reuse. These limitations require a rethink on data can be made machine and AI-ready - the key motivation behind the FAIR Guiding Principles. Concurrently, while recent efforts have explored the use of deep learning to fuse disparate data into predictive models for a wide range of biomedical applications, these models often fail even when the correct answer is already known, and fail to explain individual predictions in terms that data scientists can appreciate. These limitations suggest that new methods to produce practical artificial intelligence are still needed.
In this talk, I will discuss our work in (1) building an integrative knowledge infrastructure to prepare FAIR and "AI-ready" data and services along with (2) neurosymbolic AI methods to improve the quality of predictions and to generate plausible explanations. Attention is given to standards, platforms, and methods to wrangle knowledge into simple, but effective semantic and latent representations, and to make these available into standards-compliant and discoverable interfaces that can be used in model building, validation, and explanation. Our work, and those of others in the field, creates a baseline for building trustworthy and easy to deploy AI models in biomedicine.

THE IMPORTANCE OF MARTIAN ATMOSPHERE SAMPLE RETURN.Sérgio Sacani
The return of a sample of near-surface atmosphere from Mars would facilitate answers to several first-order science questions surrounding the formation and evolution of the planet. One of the important aspects of terrestrial planet formation in general is the role that primary atmospheres played in influencing the chemistry and structure of the planets and their antecedents. Studies of the martian atmosphere can be used to investigate the role of a primary atmosphere in its history. Atmosphere samples would also inform our understanding of the near-surface chemistry of the planet, and ultimately the prospects for life. High-precision isotopic analyses of constituent gases are needed to address these questions, requiring that the analyses are made on returned samples rather than in situ.
2. Lemuria is the name of a hypothetical "lost land"
variously located in the Indian and Pacific Oceans. The
concept's 19th-century origins lie in attempts to
account for discontinuities in bio geography; however,
the concept of Lemuria has been rendered obsolete by
modern theories of plate tectonics. Although sunken
continents do exist – like Zealandia in the Pacific as
well as Mauritia and the Kerguelen Plateau in the
Indian Ocean – there is no known geological formation
under the Indian or Pacific Oceans that corresponds to
the hypothetical Lemuria.
Introduction
3. Lemuria and Mt.Shastha
In 1894, Frederick Spencer Oliver published A Dweller on Two Planets,
which claimed that survivors from a sunken continent called Lemuria were
living in or on Mount Shasta in northern California. Oliver claimed the
Lemurians lived in a complex of tunnels beneath the mountain and
occasionally were seen walking the surface dressed in white robes.
In 1931 Harvey Spencer Lewis using the pseudonym Wisar Spenle Cerve
wrote a book (published by the Rosicrucians) about the hidden Lemurians of
Mount Shasta that a bibliography on Mount Shasta described as "responsible
for the legend's widespread popularity." This belief has since been repeated
by Guy Warren Ballard, followers of the Ascended Masters and the Great
White Brotherhood, and Bridge to Freedom, The Summit Lighthouse, Church
Universal and Triumphant, and Kryon.[citation needed]
4. Kumari Kandam and Lemuria
"Lemuria" in Tamil nationalist mysticist literature, connecting Madagascar, South India and
Australia (covering most of the Indian Ocean).
Some Tamil writers such as Devaneya Pavanar have tried to associate Lemuria with Kumari
Kandam, a legendary sunken landmass mentioned in the Tamil literature, claiming that it was
the cradle of civilization.
“Lemuria” in Tamil nationalist mysticist literature, connecting
Madagascar, South India and Australia (covering most of the Indian Ocean).
Mount Meru stretches southwards from Sri Lanka. The distance from
Madagascar to Australia is about 4,200 miles
Kumari Kandam or Lemuria (Tamil:குமரிக்கண்டம்) is the name of a
supposed sunken landmass referred to in existing ancient Tamil literature. It is
said to have been located in the Indian Ocean, to the south of present-
day Kanyakumari district at the southern tip of India.
5. In Tamil National Mysticism
In the late 19th and early 20th centuries, Tamil
nationalists came to identify Kumari Kandam
with Lemuria, a hypothetical “lost continent” posited in the
19th century to account for discontinuities
in biogeography. In these accounts, Kumari Kandam
became the “cradle of civilization”, the origin of human
languages in general and the Tamil language in particular.
These ideas gained notability in Tamil academic literature
over the first decades of the 20th century, and were
popularized by the Tanittamil Iyakkam, notably by self-
taught DravidologistDevaneya Pavanar, who held that all
languages on earth were merely corrupted Tamil dialects.

7. References In Tamil Literature
There are scattered references in Sangam literature, such as Kalittokai 104,
to how the sea took the land of the Pandiyan kings, upon which they
conquered new lands to replace those they had lost. There are also
references to the rivers Pahruli and Kumari, that are said to have flowed in a
now-submerged land. The Silappadhikaram, a 5th century epic, states that
the “cruel sea” took the Pandiyan land that lay between the rivers Pahruli and
the mountainous banks of the Kumari, to replace which the Pandiyan king
conquered lands belonging to the Chola and Chera kings (Maturaikkandam,
verses 17-22). Adiyarkkunallar, a 12th century commentator on the epic,
explains this reference by saying that there was once a land to the south of
the present-day Kanyakumari, which stretched for 700 kavatam from the
Pahruli river in the north to the Kumari river in the south. As the modern
equivalent of a kavatam is unknown, estimates of the size of the lost land
vary from 1,400 miles (2,300 km) to 7,000 miles (11,000 km) in length, to
others suggesting a total area of 6-7,000 square miles, or smaller still an area
of just a few villages.
8. This land was divided into 49 nadu, or territories, which
he names as seven coconut territories (elutenga natu),
seven Madurai territories (elumaturai natu), seven old
sandy territories (elumunpalai natu), seven new sandy
territories (elupinpalai natu), seven mountain territories
(elukunra natu), seven eastern coastal territories
(elukunakarai natu) and seven dwarf-palmterritories
(elukurumpanai natu). All these lands, he says,
together with the many-mountained land that began
with KumariKollam, with forests and habitations, were
submerged by the sea.Two of these Nadus or
territories were supposedly parts of present-
day Kollam and Kanyakumari districts.
9. Cradle of Civilization
According to the Kumari Kandam proponents, the continent was
submerged when the last ice age ended and the sea levels rose. The
Tamil people then migrated to other lands, and mixed with the other
groups, leading to the formation of new races, languages and civilizations.
Some also theorize that the entire humanity is descended from the
inhabitants of Kumari Kandam. Both narratives agree on the point that the
Tamil culture is the source of all civilized culture in the world, and Tamil is
the mother language of all other languages in the world. According to the
most versions, the original culture of Kumari Kandam survived in Tamil
Nadu.
As early as 1903, Suryanarayana Sastri, in his Tamilmoliyin Varalaru,
insisted that all the humans were descendants of the ancient Tamils from
Kumari Kandam. Such claims were repeated by several others, including
M. S. Purnalingam Pillai and Maraimalai Adigal. In 1917, Abraham
Pandithar wrote that Lemuria was the cradle of human race, and Tamil
was the first language spoken by the humans. These claims were
repeated in the school and college textbooks of Tamil Nadu throughout
the 20th century.
10. M. S. Purnalingam Pillai, writing in 1927, stated that Indus Valley
Civilization was established by the Tamil survivors from the flood-
hit Kumari Nadu. In the 1940s, N. S. Kandiah Pillai published
maps showing migration of the Kumari Kandam residents to
other parts of the world. In 1953, R. Nedunceliyan, who later
became the education minister of Tamil Nadu, insisted that the
civilization spread from South India to the Indus Valley and
Sumer, and subsequently, to "Arabia, Egypt, Greece, Italy, Spain
and other places". They presented modern Tamil as a pale
remnant of the glorious ancient Tamil language spoken in Kumari
Kandam.
Some Tamil writers also claimed that the Indo-Aryans were also
descendants of proto-Dravidians of Kumari Kandam. According
to this theory, these Indo-Aryans belonged to a branch which
migrated to Central Asia and then returned to India. Similar
explanations were used to reconcile the popular theory that
proto-Dravidians migrated to India from the Mediterranean
region. A 1975 Government of Tamil Nadu college text book
stated that the Dravidians of Kumari Kandam had migrated to the
Mediterranean region after the submergence of their continent;
later, they migrated back to India via the Himalayan passes.
11. Primordial but not Primitive
The Tamil revivalists did not consider Kumari Kandam as a primitive
society or a rural civilization. Instead, they described it as a utopia which
had reached the zenith of human achievement, and where people lived a
life devoted to learning, education, travel and commerce. Sumanthi
Ramaswamy notes that this "placemaking" of Kumari Kandam was
frequently intended as a teaching tool, meant to inspire the modern Tamils
to pursue excellence. But this pre-occupation with "civilization" was also a
response to the British rulers' projection of the Europeans as more
civilized than the Tamils.
Suryanarayan Sastri, in 1903, described the antediluvian Tamils as expert
cultivators, fine poets and far-traveling merchants, who lived in an
egalitarian and democratic society. Savariroyan Pillai, writing a few years
later, described Kumari Kandam as a seat of learning and culture.
Sivagnana Yogi (1840-1924) stated that this ancient society was free of
any caste system. Kandiah Pillai, in a 1945 work for children, wrote that
Kumarikandam was ruled by a strong and just emperor called Sengon,
who organized the sangams. In 1981, the Government of Tamil Nadu
funded a documentary film on Kumari Kandam. The film, personally
backed by the Chief Minister M. G. Ramachandran and directed by P.
Neelakantan, was screened at the Fifth International Conference of Tamil
Studies in Madurai. It combined the continental drift theory with the
submerged continent theory to present Lemuria as a scientifically valid
concept. It depicted Kumari Kandam cities resplendent with mansions,
gardens, arts, crafts, music and dance.
12. Lost Works
The Tamil revivalists insisted that the first two Tamil sangams (literary academies) were not
mythical, and happened in the Kumari Kandam era. While most Tamil revivalists did not
enumerate or list the lost Sangam works, some came up with their names, and even listed
their contents. In 1903, Suryanarayana Sastri named some of these works as Mutunarai,
Mutukuruku, Mapuranam and Putupuranam. In 1917, Abraham Pandithar listed three of
these works as the world's first treatises of music: Naratiyam, Perunarai and Perunkuruku.
He also listed several rare musical instruments such as the thousand-stringed lute, which
had been lost to the sea. Devaneya Pavanar printed an entire list of the submerged books.
Others listed books on a wide range of topics, including medicine, martial arts, logic,
painting, sculpture, yoga, philosophy, music, mathematics, alchemy, magic, architecture,
poetry, and wealth. Since these works had been lost to the sea, the Kumari Kandam
proponents insisted that no empirical proof could be provided for their claims.
In 1902, Chidambaranar published a book called Cenkonraraiccelavu, claiming that he had
'discovered' its manuscript from "some old cudgan [sic] leaves". The book was presented
as a lost-and-found work of the first Sangam at Tenmadurai. The author of the poem was
styled as Mutaluli Centan Taniyur ("Chentan who lived in Taniyur before the first deluge").
The work talked about the exploits of an antediluvian Tamil king Sengon, who ruled the
now-submerged kingdom of Peruvalanatu, the region between the rivers Kumari and
Pahruli. According to Chidambaranar, Sengon was a native of Olinadu, which was located
south of the Equator; the king maintained several battleships and conquered lands as far
as Tibet. In 1950s, Cenkonraraiccelavu was declared as a forgery by S. Vaiyapuri Pillai.
However, this did not stop the Tamil revivalists from invoking the text. The 1981
documentary funded by Government of Tamil Nadu declared it as the "world's first
travelogue".
13. Maps
The first map to visualize Lemuria as an ancient Tamil territory was published by S.
Subramania Sastri in 1916, in the journal Centamil. This map was actually part of an
article that criticized the pseudohistorical claims about a lost continent. Sastri insisted that
the lost land mentioned in Adiyarkunallar's records was barely equivalent to a taluka (not
larger than a few hundred square miles). The map depicted two different versions of
Kumari Kandam: that of Sastri, and that of A. Shanmugam Pillai. The lost land was
depicted as a peninsula, similar to the present-day Indian peninsula.
In 1927, Purnalingam Pillai published a map titled "Puranic India before the Deluges", in
which he labeled the various places of Kumari Kandam with names drawn from ancient
Tamil and Sanskrit literary works. Pulavar Kulanthai, in his 1946 map, was first to depict
cities like Tenmaturai and Kapatapuram on the maps of Kumari Kandam. Several maps
also depicted the various mountain ranges and rivers of Kumari Kandam. The most
elaborate cartographic visualization appeared in a 1977 map by R. Mathivanan. This map
showed the 49 nadus mentioned by Adiyarkunallar, and appears in the Tamil Nadu
government's 1981 documentary.
A 1981 map published by N. Mahalingam depicted the lost land as "Submerged Tamil
Nadu" in 30,000 B.C. A 1991 map, created by R. Mathivanan, showed a land bridge
connecting Indian peninsula to Antarctica. A few Tamil writers also depicted
Gondwanaland as Kumari Kandam.
