The document discusses the unit circle and how it relates to trigonometric functions. It defines the unit circle as a circle with radius of 1 unit and describes how trig functions are defined based on the coordinates (x,y) of points along the unit circle. It also discusses how the domain of sine and cosine is all real numbers, while their period is 2π - meaning the functions repeat their output values every 2π radians.
Discusses trigonometric functions, graphing, and defining using the Unit Circle. Explains how to convert from radians to degrees, and vice versa. Describes how to calculate arc lengths in given circles.
THE BINOMIAL THEOREM shows how to calculate a power of a binomial –
(x+ y)n -- without actually multiplying out.
For example, if we actually multiplied out the 4th power of (x + y) --
(x + y)4 = (x + y) (x + y) (x + y) (x + y)
-- then on collecting like terms we would find:
(x + y)4 = x4 + 4x3y + 6x2y2 + 4xy3 + y4 . . . . . (1)

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 .

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.
(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.

What You Should Learn
• Identify a unit circle and describe its relationship
to real numbers.
• Evaluate trigonometric functions using the unit
circle.
• Use domain and period to evaluate sine and
cosine functions and use a calculator to
evaluate trigonometric functions.
4. 4
The Unit Circle
The two historical perspectives of trigonometry incorporate
different methods of introducing the trigonometric functions.
Our first introduction to these functions is based on the unit
circle.
Consider the unit circle given by
x2 + y2 = 1
It is called the unit circle because it has
a radius of one unit.
Figure 4.18
Unit circle
5. 5
The Unit Circle
As you graph any angle on the unit circle, there is a point
where its terminal side intersects the circle. The point is
(x, y)
If you graph an angle of 0 degrees or 0 radians, the
terminal side intersection corresponds to the point (1, 0).
Moreover, because the unit circle has a
circumference of 2, the angle 2 also corresponds to the
point (1, 0).
7. 7
The Trigonometric Functions
You can use these coordinates to define the six
trigonometric functions.
sine cosine tangent
cosecant secant cotangent
These six functions are normally abbreviated sin, cos, tan,
csc, sec, and cot, respectively.
9. 9
The Trigonometric Functions
In the definitions of the trigonometric functions, note that
the tangent and secant are not defined when x = 0.
For instance, because t = /2 corresponds to (x, y) = (0, 1),
it follows that tan(/2) and sec(/2) are undefined.
Similarly, the cotangent and cosecant are not defined when
y = 0.
For instance, because t = 0 corresponds to (x, y) = (1, 0),
cot 0 and csc 0 are undefined.
10. 10
Example 1 – Evaluating Trigonometric Functions
Evaluate the six trigonometric functions at each real
number.
a. b. c.
Solution:
For each t-value, begin by finding the corresponding point
(x, y) on the unit circle. Then use the definitions of
trigonometric functions.
15. 15
Domain and Period of Sine and Cosine
Please read this slide and the next three, but do not copy
them down.
The domain of the sine and cosine functions is the set of all
real numbers.
To determine the range of these two functions, consider the
unit circle shown to the right.
16. 16
Domain and Period of Sine and Cosine
Adding 2 to each value of in the interval [0, 2] completes
a second revolution around the unit circle, as shown in
Figure 4.23.
Figure 4.23
17. 17
Domain and Period of Sine and Cosine
The values of sin(t + 2) and cos(t + 2) correspond to
those of sin t and cos t.
Similar results can be obtained for repeated revolutions
(positive or negative) around the unit circle. This leads to
the general result
sin(t + 2n) = sint and cos(t + 2n) = cost
for any integer n and real number t. Functions that behave
in such a repetitive (or cyclic) manner are called periodic.
18. 18
Domain and Period of Sine and Cosine
It follows from the definition of periodic function that the
sine and cosine functions are periodic and have a period of
2. The other four trigonometric functions are also periodic.
19. 19
Domain and Period of Sine and Cosine
A function f is even when
f(–t) = f(t)
and is odd when
f(–t) = –f(t)
Of the six trigonometric functions, two are even and four
are odd.
20. 20
Example 2 – Using the Period to Evaluate Sine and Cosine
Because y you have
