(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.

Earliest Galaxies in the JADES Origins Field: Luminosity Function and Cosmic ...Sérgio Sacani
We characterize the earliest galaxy population in the JADES Origins Field (JOF), the deepest
imaging field observed with JWST. We make use of the ancillary Hubble optical images (5 filters
spanning 0.4−0.9µm) and novel JWST images with 14 filters spanning 0.8−5µm, including 7 mediumband filters, and reaching total exposure times of up to 46 hours per filter. We combine all our data
at > 2.3µm to construct an ultradeep image, reaching as deep as ≈ 31.4 AB mag in the stack and
30.3-31.0 AB mag (5σ, r = 0.1” circular aperture) in individual filters. We measure photometric
redshifts and use robust selection criteria to identify a sample of eight galaxy candidates at redshifts
z = 11.5 − 15. These objects show compact half-light radii of R1/2 ∼ 50 − 200pc, stellar masses of
M⋆ ∼ 107−108M⊙, and star-formation rates of SFR ∼ 0.1−1 M⊙ yr−1
. Our search finds no candidates
at 15 < z < 20, placing upper limits at these redshifts. We develop a forward modeling approach to
infer the properties of the evolving luminosity function without binning in redshift or luminosity that
marginalizes over the photometric redshift uncertainty of our candidate galaxies and incorporates the
impact of non-detections. We find a z = 12 luminosity function in good agreement with prior results,
and that the luminosity function normalization and UV luminosity density decline by a factor of ∼ 2.5
from z = 12 to z = 14. We discuss the possible implications of our results in the context of theoretical
models for evolution of the dark matter halo mass function.
Observation of Io’s Resurfacing via Plume Deposition Using Ground-based Adapt...Sérgio Sacani
Since volcanic activity was first discovered on Io from Voyager images in 1979, changes
on Io’s surface have been monitored from both spacecraft and ground-based telescopes.
Here, we present the highest spatial resolution images of Io ever obtained from a groundbased telescope. These images, acquired by the SHARK-VIS instrument on the Large
Binocular Telescope, show evidence of a major resurfacing event on Io’s trailing hemisphere. When compared to the most recent spacecraft images, the SHARK-VIS images
show that a plume deposit from a powerful eruption at Pillan Patera has covered part
of the long-lived Pele plume deposit. Although this type of resurfacing event may be common on Io, few have been detected due to the rarity of spacecraft visits and the previously low spatial resolution available from Earth-based telescopes. The SHARK-VIS instrument ushers in a new era of high resolution imaging of Io’s surface using adaptive
optics at visible wavelengths.

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 .
2. Diaster word come from the Italian word Disastro.
The meaning Disaster is Dis:- bad & Aster :- star.
It means it is an astrological senses of a calamity
blame on the position of planet.
4. An earthquake is also known as a quake, tremor or
temblor.
Earthquake is the shaking of the surface of the
Earth, resulting from the sudden release of energy
in the Earth's lithosphere that creates seismic
waves.
5. Epicenter-The point on the Earth's surface located
directly above the focus of an earthquake.
Focus-The location where the earthquake begins.
The ground ruptures at this spot, then seismic
waves radiate outward in all directions.

7. 1. Volcanic Eruptions
2.Tectonic Movements
3.Geological Faults
4.Man Made
5.Minor Causes
•Volcanic eruption:- The main cause of earthquake is volcanic
eruptions. Such type of earthquakes occurs in areas, with frequent
volcanic activities. When boiling lava tries to break through the surface of
the earth, with the increased pressure of gases, certain movements are
caused in earth’s crust.
8. •Tectonic Movements :-The surface of the earth consists of
some plates, comprising of the upper mantle. These plates are
always moving, thus effecting earth’s crust. These movements are
categorized into three types: constructive, destructive and
conservative. Constructive is when two plates move away from each
other, they correspond to mild earthquakes.
•Geological Faults:- A geological fault is known as the
displacement of plates of their original plane. The plane can be
horizontal or vertical. These planes are not formed suddenly but
slowly develop over a long period. The movement of rocks along
these planes brings about tectonic earthquakes.
9. •Man Made:- The interference of man with nature can also
become a cause of the earthquake. The disturbance of crustal balance
due to heavy clubbing of water in dams can cause earthquakes.
•Minor Causes:- Some minor causes such as landslides,
avalanches, the collapse of heavy rocks, etc. can also cause minor
shockwaves. The gases beneath the surface of earth contract and
expand, giving rise to movements in plates beneath the crust.
10. Effects of Earthquake
The effects of an earthquake are terrible and devastating. Many
building, hospitals, schools, etc are destroyed due to it. A lot of
people get killed and injured. Many people lose their money
and property. It affects the mental health and emotional health
of people.
The environmental effects of it are that including
surface faulting, tectonic uplift and subsidence, tsunamis, soil
liquefaction, ground resonance, landslides and ground failure,
either directly linked to a quake source or provoked by the
ground shaking.
11. Earthquakes – Mitigation
(Actions Before, During, After)
•Action to be taken before Earthquake:-
1. Make sure you have a fire extinguisher, first aid kit, a battery-powered
radio, a flashlight, and extra batteries at home.
2. Learn first aid.
3. Learn how to turn off the gas, water, and electricity.
4. Make up a plan of where to meet your family after an earthquake.
5. Don't leave heavy objects on shelves (they'll fall during a quake).
12. •Action to be taken during Earthquake:-
1. Stay calm!
2. If you're indoors, stand against a wall near the center of
the building, stand in a doorway, or crawl under heavy
furniture (a desk or table). Stay away from windows and
outside doors.
3. If you're outdoors, stay in the open away from power
lines or anything that might fall. Stay away from
buildings (stuff might fall off the building or the building
could fall on you).
4. Don't use matches, candles, or any flame. Broken gas
lines and fire don't mix
5. If you're in a car, stop the car and stay inside the car until
the earthquake stops.
6. Don't use elevators (they'll probably get stuck anyway)
13. •Action to be taken after Earthquake:-
1. Check yourself and others for injuries. Provide first aid for anyone
who needs it.
2. Check water, gas, and electric lines for damage. If any are
damaged, shut off the valves. Check for the smell of gas. If you
smell it, open all the windows and doors, leave immediately, and
report it to the authorities
3. Turn on the radio. Don't use the phone unless it's an emergency.
4. Stay out of damaged buildings.
5. Stay away from beaches. Tsunamis and seiches sometimes hit after
the ground has stopped shaking.
6. Stay away from damaged areas.

17. 2001 Gujarat Earthquake
India Faced One of its Worst
Disasters in 2001
The 2001 Gujarat earthquake, also known as the Bhuj earthquake,
occurred on 26 January, India's 51st Republic Day, at 08:46 AM
IST and lasted for over 2 minutes. The epicentre was about 9 km
south-southwest of the village
of Chobari in Bhachau Taluka of Kutch District of Gujarat, India.
More than 19,727people were killed while 166,000 were injured and
nearly millions were left homeless.
When India was celebrating its Republic Day on 26 January 2001,
the western part of the country faced one of the worst earthquakes in
history.
