A protein synthesis inhibitor is a substance that stops or slows the growth or proliferation of cells by disrupting the processes that lead directly to the generation of new proteins. All of the antibiotics that target bacterial protein synthesis do so by interacting with the bacterial ribosome and inhibiting its function. The ribosome might not seem like a very good target for selective toxicity, because all cells, including our own, use ribosomes for protein synthesis.The good thing is that bacteria and eukaryotes have ribosomes that are structurally different. Bacteria have so-called 70S ribosomes and eukaryotes have 80S ribosomes. No, not '70s and '80s ribosomes, although that would be pretty entertaining. The S stands for 'Svedberg unit,' and it refers to the rate at which particles sediment down into the tube during high-speed ultracentrifugation. Basically, it tells us about the ribosome's molecular weight and shape.
70S and 80S ribosomes are different enough that antibiotics can specifically target one and not the other. Let's take a closer look at the bacterial 70S ribosome and see where some different kinds of antibiotics act on it. Remember that ribosomes are made of RNA and protein and that they have two subunits, one large and one small.
The bacterial 70S ribosome's subunits are the 50S subunit and the 30S subunit. Yes, I know, 50 + 30 = 80, not 70, but this is not a math mistake. Using the Svedberg unit to measure ribosomes means that things don't always add up perfectly, because rates of sedimentation are not additive like molecular weights are.
Before we get into the specifics of how antibiotics inhibit bacterial ribosomes, let's briefly review how ribosomes work. First, a tRNA loaded with a particular amino acid enters the ribosome at the A site. The tRNA's anticodon has to match the codon, or group of three nucleotides on the mRNA. Then, at the P site of the ribosome, a peptide bond forms between the previous amino acid and the new amino acid. Finally, the empty tRNA exits at the E site. This process repeats for the whole length of the mRNA, and the polypeptide chain continues to grow.

Most species have two sexes: male and female. Each sex has its own unique reproductive system. They are different in shape and structure, but both are specifically designed to produce, nourish, and transport either the egg or sperm.
Unlike the female, whose sex organs are located entirely within the pelvis, the male has reproductive organs, or genitals, that are both inside and outside the pelvis. The male genitals include:
the testicles
the duct system, which is made up of the epididymis and the vas deferens
the accessory glands, which include the seminal vesicles and prostate gland
the penis
Major Function:
Makes sperm cells (gametes) and transfer the sperm into the female reproductive system in order to fertilize the female gametes to produce a zygote.

Putting the SPARK into Virtual Training.pptxCynthia Clay
This 60-minute webinar, sponsored by Adobe, was delivered for the Training Mag Network. It explored the five elements of SPARK: Storytelling, Purpose, Action, Relationships, and Kudos. Knowing how to tell a well-structured story is key to building long-term memory. Stating a clear purpose that doesn't take away from the discovery learning process is critical. Ensuring that people move from theory to practical application is imperative. Creating strong social learning is the key to commitment and engagement. Validating and affirming participants' comments is the way to create a positive learning environment.

Implicitly or explicitly all competing businesses employ a strategy to select a mix
of marketing resources. Formulating such competitive strategies fundamentally
involves recognizing relationships between elements of the marketing mix (e.g.,
price and product quality), as well as assessing competitive and market conditions
(i.e., industry structure in the language of economics).

Unveiling the Secrets How Does Generative AI Work.pdfSam H
At its core, generative artificial intelligence relies on the concept of generative models, which serve as engines that churn out entirely new data resembling their training data. It is like a sculptor who has studied so many forms found in nature and then uses this knowledge to create sculptures from his imagination that have never been seen before anywhere else. If taken to cyberspace, gans work almost the same way.

Understanding business valuation is crucial for making informed decisions, whether you're seeking investment, planning to sell, or simply want to gauge your company's worth.
2. TWO MAJOR DIVISIONS
• The Central Nervous System (CNS)
• Peripheral Nervous System (PNS)
3. THE CENTRAL NERVOUS SYSTEM
Controls the center of the body;
• relays messages
•processes information
•analyzes information
4. PARTS THAT MAKE UP THE CNS
• Cerebrum: largest most prominent region of the
human brain (front of the brain). Responsible for the
voluntary or conscious, activity of the body. Site of
intelligence, learning and judgment.
• Cerebellum: second largest region of the brain.
Coordinates and balances the actions of the
muscles. (back of the brain)
• Thalamus: receives messages from all the sensory
receptors throughout the body and then relays
information to the proper region of the cerebrum for
further processing.
5. THE PERIPHERAL NERVOUS SYSTEM
• Nerves stimulate regions of the head and neck,
spinal nerves, and ganglia.
• It can be divided into the sensory division and the
motor division
• Sensory division: transmits impulses from sense
organs to central nervous system.
• Motor division: transmits impulses from the central
nervous system to the muscles or glands.
6. THE NERVOUS SYSTEM :
COMMUNICATION
•A. Neurons = masses of nerve cells that transmit
information
1. Cell Body - contains the nucleus and two extensions
2. Dendrites – shorter, more numerous, receive
information
3. Axons – single, long “fiber” which conducts impulse
away from the cell body, sends information
9. HUMAN CIRCULATORY SYSTEM
• Systemic Circulation –
delivers blood to all
body cells and carries
away waste
• Pulmonary
Circulation –
eliminates carbon
dioxide and
oxygenates blood
(lung pathway)
10. STRUCTURE OF THE HEART
• Heart Size: (size of a
fist) approximately 14
cm x 9 cm
• Located in the
mediastinum (space
between lungs,
backbone, sternum),
between the 2nd rib
and the 5th
intercostal space.
• The distal end of the
heart is called the
apex
11. WALLS OF THE HEART
• Epicardium – outer
layer, reduces
friction
• Myocardium –
middle layer, mostly
cardiac muscle
• Endocardium – thin
inner lining, within
chambers of the
heart
12. HEART CHAMBERS & VALVES
• Heart has 4 chambers:
• 2 Atria – thin upper
chambers that receive
blood returning to the
heart through veins.. Right
and Left Atrium
• 2 Ventricles – thick,
muscular lower chambers.
Receive blood from the
atria above them. Force
(pump) blood out of the
heart through arteries.
Right and left ventricle.
• Septum – separates the
right and left sides of the
heart
13. Valves of the Heart – allow one-way flow
of blood
• 4 total (2 Atrioventricular • Pulmonary Semilunar, or
Valves (AV) & 2 Semilunar just pulmonary valve.
valves) Between the left ventricle
• Left Atrioventricular valve and the aorta
– also called the bicuspid
valve or mitral valve.
Between left atrium and
ventricle
• Right Atrioventricular
valve – also called the
tricuspid valve. Between
right atrium and ventricle
• Aortic Semilunar – or just
aortic valve. Between the
left ventricle and the
aorta
14. BLOOD VESSELS
•Blood Vessels: arteries, veins, capillaries
•ARTERIES : strong elastic vessels which carry blood
moving away from the heart. Smallest ones are
arterioles which connect to capillaries.
•VEINS - Thinner, less muscular vessels carrying blood
toward the heart.
•Smallest ones are called venules which connect to
capillaries. Contain valves.
15. CAPILLARIES
Penetrate nearly all
tissues. Walls are
composed of a single
layer of squamous
cells – very thin.
Critical function:
allows exchange of
materials (oxygen,
nutrients) between
blood and tissues.
16. MAJOR BLOOD VESSELS
• Aorta - Ascending Aorta, Aortic
Arch, Descending Aorta, Abdominal
Aorta. The aorta is the largest artery.
(leaves left ventricle)
• Pulmonary Trunk – splits into left and
right, both lead to the lungs (leaves
left ventricle)
• Pulmonary Veins – return blood from
the lungs to the heart (connects to
left atrium)
•
• Superior and Inferior Vena Cava –
return blood from the head and body
to the heart (connects to right atrium)
18. MALE REPRODUCTIVE SYSTEM
• Function: Produces and delivers sperm
• Parts: scrotum, seminiferous tubules, epididymis, vas
deferens, testes, urethra, penis
19. PARTS
• Scrotum: where testes • Vas deferens: the tube
remain outside the that carries sperm from
body cavity. the epididymis to the
Temperature 37°C. urethra.
• Seminiferous tubules: • Urethra: tube that
located in the testis are carries urine from the
clusters of hundreds of bladder and releases it
tiny tubules. from the body.
• Epididymis: where fully • Penis: contain a

• Testes: makes sperms, the body.
produces testosterone.
21. FEMALE REPRODUCTION
• OVARY - this is where the eggs
are produced through cell
division (MEIOSIS)
• - each ovary takes turns
releasing eggs every month,
twins occur if two eggs are
released
• Ovaries secrete both estrogen
and progesterone.
• Estrogen is responsible for the
appearance of secondary sex
characteristics of females
• Progesterone regulates
menstruation
22. EMBRYO DEVELOPMENT
• An egg is usually a
few days old before
it implants in the
uterus. At this point,
it has already
divided several
times and is called
a blastula.
23. Uterus
• The uterus consists of a body
and a cervix. The cervix
protrudes into the vagina.
• The uterus maintains an
environment for accepting a
fertilized egg.
• The fertilized ovum becomes
an embryo, attaches to a wall
of the uterus, creates a
placenta, and develops into a
fetus (gestates) until childbirth.
• If no fertilized egg reaches the
uterus, the lining is shed
monthly in a process known as
menstruation
