This document discusses nutrition in plants and animals. It begins by introducing the group members and defining nutrition as the interaction of nutrients in food. It then describes two types of nutrition - autotrophic in plants which prepare their own food, and heterotrophic in organisms like humans which depend on other organisms for food. The document proceeds to discuss plant nutrition including photosynthesis, and animal nutrition exemplified by the processes in amoeba and the human digestive system.

(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.
Richard's entangled aventures in wonderlandRichard Gill
Since the loophole-free Bell experiments of 2020 and the Nobel prizes in physics of 2022, critics of Bell's work have retreated to the fortress of super-determinism. Now, super-determinism is a derogatory word - it just means "determinism". Palmer, Hance and Hossenfelder argue that quantum mechanics and determinism are not incompatible, using a sophisticated mathematical construction based on a subtle thinning of allowed states and measurements in quantum mechanics, such that what is left appears to make Bell's argument fail, without altering the empirical predictions of quantum mechanics. I think however that it is a smoke screen, and the slogan "lost in math" comes to my mind. I will discuss some other recent disproofs of Bell's theorem using the language of causality based on causal graphs. Causal thinking is also central to law and justice. I will mention surprising connections to my work on serial killer nurse cases, in particular the Dutch case of Lucia de Berk and the current UK case of Lucy Letby.

3. INTRODUCTION
• Nutrition is the science that interprets the interaction
of nutrients and other substances in food (e.g.
phytonutrients,anthocyanins, tannins, etc.) in relation
to maintenance, growth, reproduction, health and
disease of an organism. It includes food intake,
absorption, assimilation, biosynthesis, catabolism
and excretion.
4. MODES OF NUTRITION
AUTOTROPHIC NUTRITION
• Organisms that prepare their own
food are called autotrophs.
• Eg. Plants
HETEROTROPHIC NUTRITION
• Organisms which depend on other
organisms for food are called
heterotrophs.
• Eg. Human beings
.
6. PLANT NUTRITION
• It is the study of the chemical elements and
compounds that are necessary for plant growth,
and also of their external supply and internal
metabolism. In 1972, E. Epstein defined two criteria
for an element to be essential for plant growth:
• in its absence the plant is unable to complete a
normal life cycle; or
• that the element is part of some essential plant
constituent or metabolite.

8. PHOTOSYNTHESIS
• It is the process by which plants prepare food by using
carbon dioxide and water in the presence of sunlight
and chlorophyll. The food prepared is carbohydrate
which is stored in the form of starch. Oxygen is released
during this Process.
• EQUATION OF PHOTOSYNTHESIS
• Sunlight
• 6CO2 + 12H20 -------------------------> C6H1206 + 6H20 + 6O2
• Chlorophyll
• 6CO2 + 6H2O ------> C6H12O6 + 6O2
• 6CO2 + 6H2O ------> C6H12O6 + 6O2

10. PROCESS OF PHOTOSYNTHESIS
Photosynthesis mainly takes place in three steps:
• Absorption of Light Energy By Chlorophyll
• Conversion of Light energy into Chemical energy and
splitting up of water molecules into Hydrogen and Oxygen
• Reduction of Carbon Dioxide by Hydrogen to form
Carbohydrates
13. • Amoeba is a unicellular animal living in water. It takes in
food by forming a finger like projections called
pseudopodia and forms a food vacuole. Inside the food
vacuole the food is digested and absorbed. The undigested
food is then sent out through the surface of the cell.
14. NUTRITION IN HUMAN BEINGS
• Nutrition in human beings take place in the digestive
system. It consists of the alimentary canal and glands which
produce enzymes which breaks down food into smaller
molecules.
• The main organs of the digestive system are mouth,
esophagus, stomach, small intestine, large intestine and
anus.
• The main glands are salivary glands, gastric glands, liver,
pancreas and intestinal glands.

17. WHAT HAPPENS TO FOOD AFTER
YOU EAT IT??
• In the mouth: The food is broken into smaller particles by the
teeth and mixed with saliva from the salivary glands. Saliva
contains the enzymes salivary amylase which converts
starch into sugar. Then the food passes through the
oesophagus.
• In the stomach: The gastric glands produce gastric juice
which contains the enzyme pepsin Hcl and mucous. Pepsin
breaks down proteins. Hcl makes the medium acidic and
helps in the action of pepsin. Mucous protects the wall of
the stomach from the action of the acid. Then the food
passes into the small intestine.
18. • In the upper part of the small intestine (duodenum):
The food is mixed with bile from liver and pancreatic juice from the
pancreas. Bile breaks down fats into globules. Pancreatic jiuce the
enzymes trypsin and lipase . Trypsin breaks down proteins and lapse
breaks down fats.
• In the small intestine :
The glands the walls of the small intestine produces intestinal juice.
The enzymes of the intestinal juice converts carbohydrates into
glucose fats into fatty acids and glycerol and proteins into amino
acids. The walls of the small intestine has several finger like
projections called villi having blood vessels. The digested food is
absorbed by the blood and the undigested food passes to the large
intestine.
19. • In the large intestine:
• Water is absorbed and the waste materials is removed through the anus.
