"Diarrhea can be a disruptive and uncomfortable gastrointestinal condition that affects individuals of all ages. Fortunately, there are effective anti-diarrhea drugs and treatments available to alleviate symptoms and restore digestive health.
Anti-diarrhea medications, such as loperamide and bismuth subsalicylate, work by slowing down the contractions of the intestinal muscles, reducing the frequency of bowel movements and helping to control loose stools. These over-the-counter options can provide quick relief from acute diarrhoea.
In this slideshare we gonna discuss about Mania Disorder, a key component of Bipolar Disorder, is a mental health condition characterized by extreme mood swings, with episodes of mania at one end and depressive states on the other. This comprehensive presentation delves into the complexities of Mania Disorder, shedding light on its symptoms, underlying causes, and the range of treatment options available.

Parkinson's disease (PD) is a complex neurodegenerative disorder characterized by the progressive degeneration of dopaminergic neurons in the substantia nigra region of the brain. This degeneration results in a wide range of motor and non-motor symptoms, including bradykinesia, rigidity, tremors, and postural instability. PD not only affects motor function but also leads to cognitive and psychiatric impairments, significantly reducing the quality of life for those afflicted.

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.

The ability to recreate computational results with minimal effort and actionable metrics provides a solid foundation for scientific research and software development. When people can replicate an analysis at the touch of a button using open-source software, open data, and methods to assess and compare proposals, it significantly eases verification of results, engagement with a diverse range of contributors, and progress. However, we have yet to fully achieve this; there are still many sociotechnical frictions.
Inspired by David Donoho's vision, this talk aims to revisit the three crucial pillars of frictionless reproducibility (data sharing, code sharing, and competitive challenges) with the perspective of deep software variability.
Our observation is that multiple layers — hardware, operating systems, third-party libraries, software versions, input data, compile-time options, and parameters — are subject to variability that exacerbates frictions but is also essential for achieving robust, generalizable results and fostering innovation. I will first review the literature, providing evidence of how the complex variability interactions across these layers affect qualitative and quantitative software properties, thereby complicating the reproduction and replication of scientific studies in various fields.
I will then present some software engineering and AI techniques that can support the strategic exploration of variability spaces. These include the use of abstractions and models (e.g., feature models), sampling strategies (e.g., uniform, random), cost-effective measurements (e.g., incremental build of software configurations), and dimensionality reduction methods (e.g., transfer learning, feature selection, software debloating).
I will finally argue that deep variability is both the problem and solution of frictionless reproducibility, calling the software science community to develop new methods and tools to manage variability and foster reproducibility in software systems.

3. DEFINITION:-
Genome is a complete set of genetic material with in a organism
CHROMATIN :- It is in nucleus and thread like coiled structures and it is further
undergoes condensation to form chromosomes and suspended in nucleosome.
It has 2 varied categories are
EUCHROMATIN — uncoiled and active
HETEROCHROMATIN —condensed and inactive
Chemical composition of chromatin
•DNA — 22-40%
•RNA — 5-10%
•PROTIEN — 55-60% —> Histones (60%) and Non-histones(20%)
4. HISTONE:-
It is one of the major protiens in chromatin. These are also present in amino acids and
facilitate to bind with negatively charged DNA
In these also we have some varieties depends upon her nature are H1, H2A, H2B, H3 &
H4
NUCLEOSOMES :-
It is combination of 200 base pairs of chromatin and it is united of DNA packaging in
eukaryotes
5. EUKARYOTIC CELLS :- DNA is associated with basic proteins to form cytoplasm in
nucletiod region and structural protiens are named as histone.
HOW GENOME IS IN CELLS :-
PROKARYOTIC CELLS :- DNA is single circular chromosomes without basic protiens

8. CHROMOSOME:-
The chromatin material is thin thread like interwined mass of chromosome material
usually present in the nucleus and is composed ofthe genetic substance. Chromatin
material is composed of DNA (deoxyribonucleic acid) and proteins (histone and acidic
proteins). Chromatin is formed of repeating subunits, the nucleosomes, each of which
has a DNA molecule coiled around a disc of histones. The chromatin is condensed into
chromosomes during the cell division. Chromosomes are visible as rod-shaped
structures only when the cell is about to divide.
Chromosomes contain hereditary information of the cell in the form of genes. DNA
stores al the information necessary for the cell to function e.g. metabolism, growth
and reproduction.
