The digestive system breaks down food through mechanical and chemical digestion and absorbs nutrients from digested food into the bloodstream. The major organs of the digestive system include the esophagus, stomach, small and large intestines, liver, gallbladder and pancreas. Common medical terms related to the digestive system include gastrointestinal, referring to the series of hollow organs from mouth to anus, nasogastric pertaining to the nose and stomach, hepatitis B virus which is a liver infection spread through bodily fluids, fecal occult blood test which detects hidden blood in stool, and inflammatory bowel disease which causes inflammation in the digestive tract.

Hepatitis is inflammation of the liver tissue. It is caused by virus or bacterial infections or continuous exposure to alcohol, drugs or toxic chemicals.
Hepatitis results from an autoimmune disorder, in which the body mistakenly sends disease-fighting cells to attack its own healthy tissue. Thus the liver reduces the ability to perform life-preserving functions. Visit us @ http://bit.ly/2OCXz7v
Slide 1: Title Slide
Extrachromosomal Inheritance
Slide 2: Introduction to Extrachromosomal Inheritance
Definition: Extrachromosomal inheritance refers to the transmission of genetic material that is not found within the nucleus.
Key Components: Involves genes located in mitochondria, chloroplasts, and plasmids.
Slide 3: Mitochondrial Inheritance
Mitochondria: Organelles responsible for energy production.
Mitochondrial DNA (mtDNA): Circular DNA molecule found in mitochondria.
Inheritance Pattern: Maternally inherited, meaning it is passed from mothers to all their offspring.
Diseases: Examples include Leber’s hereditary optic neuropathy (LHON) and mitochondrial myopathy.
Slide 4: Chloroplast Inheritance
Chloroplasts: Organelles responsible for photosynthesis in plants.
Chloroplast DNA (cpDNA): Circular DNA molecule found in chloroplasts.
Inheritance Pattern: Often maternally inherited in most plants, but can vary in some species.
Examples: Variegation in plants, where leaf color patterns are determined by chloroplast DNA.
Slide 5: Plasmid Inheritance
Plasmids: Small, circular DNA molecules found in bacteria and some eukaryotes.
Features: Can carry antibiotic resistance genes and can be transferred between cells through processes like conjugation.
Significance: Important in biotechnology for gene cloning and genetic engineering.
Slide 6: Mechanisms of Extrachromosomal Inheritance
Non-Mendelian Patterns: Do not follow Mendel’s laws of inheritance.
Cytoplasmic Segregation: During cell division, organelles like mitochondria and chloroplasts are randomly distributed to daughter cells.
Heteroplasmy: Presence of more than one type of organellar genome within a cell, leading to variation in expression.
Slide 7: Examples of Extrachromosomal Inheritance
Four O’clock Plant (Mirabilis jalapa): Shows variegated leaves due to different cpDNA in leaf cells.
Petite Mutants in Yeast: Result from mutations in mitochondrial DNA affecting respiration.
Slide 8: Importance of Extrachromosomal Inheritance
Evolution: Provides insight into the evolution of eukaryotic cells.
Medicine: Understanding mitochondrial inheritance helps in diagnosing and treating mitochondrial diseases.
Agriculture: Chloroplast inheritance can be used in plant breeding and genetic modification.
Slide 9: Recent Research and Advances
Gene Editing: Techniques like CRISPR-Cas9 are being used to edit mitochondrial and chloroplast DNA.
Therapies: Development of mitochondrial replacement therapy (MRT) for preventing mitochondrial diseases.
Slide 10: Conclusion
Summary: Extrachromosomal inheritance involves the transmission of genetic material outside the nucleus and plays a crucial role in genetics, medicine, and biotechnology.
Future Directions: Continued research and technological advancements hold promise for new treatments and applications.
Slide 11: Questions and Discussion
Invite Audience: Open the floor for any questions or further discussion on the topic.
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.
Deep Behavioral Phenotyping in Systems Neuroscience for Functional Atlasing a...Ana Luísa Pinho
Functional Magnetic Resonance Imaging (fMRI) provides means to characterize brain activations in response to behavior. However, cognitive neuroscience has been limited to group-level effects referring to the performance of specific tasks. To obtain the functional profile of elementary cognitive mechanisms, the combination of brain responses to many tasks is required. Yet, to date, both structural atlases and parcellation-based activations do not fully account for cognitive function and still present several limitations. Further, they do not adapt overall to individual characteristics. In this talk, I will give an account of deep-behavioral phenotyping strategies, namely data-driven methods in large task-fMRI datasets, to optimize functional brain-data collection and improve inference of effects-of-interest related to mental processes. Key to this approach is the employment of fast multi-functional paradigms rich on features that can be well parametrized and, consequently, facilitate the creation of psycho-physiological constructs to be modelled with imaging data. Particular emphasis will be given to music stimuli when studying high-order cognitive mechanisms, due to their ecological nature and quality to enable complex behavior compounded by discrete entities. I will also discuss how deep-behavioral phenotyping and individualized models applied to neuroimaging data can better account for the subject-specific organization of domain-general cognitive systems in the human brain. Finally, the accumulation of functional brain signatures brings the possibility to clarify relationships among tasks and create a univocal link between brain systems and mental functions through: (1) the development of ontologies proposing an organization of cognitive processes; and (2) brain-network taxonomies describing functional specialization. To this end, tools to improve commensurability in cognitive science are necessary, such as public repositories, ontology-based platforms and automated meta-analysis tools. I will thus discuss some brain-atlasing resources currently under development, and their applicability in cognitive as well as clinical neuroscience.
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.

2. Digestive
System
The digestive system is responsible for breaking down food
through mechanical and chemical digestion. Once digested,
nutrient molecules are absorbed and then enter the blood stream,
anything that is not digested us eliminated into solid waste.
4. Medical terms relating to the
Digestive System
• Gastroin Testinal
• Nasogastric
• Hepatitis B Virus
• Fecal Occult Blood Test
• Inflammatory Bowel Disease
5. Gastroin Testinal
• A series of “hollow” organs
joined in a long, twisting tube
from mouth to the anus. These
organs consist of : Mouth,
Esophogus, Stomach, Small
Intestine, and Large Intestine
which includes the rectum and
anus.
6. Nasogastric
nas/o + gastr/ic = Pertaining to the nose and stomach
A nasogastric intubation is medical procedure which involves
placing a plastic tube through the nose and feeding it down
your your throat and into your stomach. This procedure is to
diagnose any problems your may have. Bleeding, aspiration,
feeding, etc.
7. Hepatitis B Virus
hepat/o + -itis = Inflammation of the liver
Hepatitis B Virus: Also known as ‘HBV’ is a
liver infection which is transmitted from blood,
semen, or another body fluid from a infected
person to a none infected person. This can
happen through birth, any sort of drug
equipment or through sexual contact.
8. Fecal occult blood test
(FOBT)
This procedure is to
determine if there is
invisible or microscopic
blood present. This blood
test can determine if there
is growth or a cancerous
tumor in your rectum. If
blood is found, the doctor
will then determine where
the blood is coming from.
9. Inflammatory bowel disease
(IBD)
IBD is inflammation of all or part of
your digestive tract. This disease
usually results in ulcers lining the
membrane. This typically involves
severe diarrhea, pain, fatigue and
weight loss.
