ESR spectroscopy in liquid food and beverages.pptxPRIYANKA PATEL
With increasing population, people need to rely on packaged food stuffs. Packaging of food materials requires the preservation of food. There are various methods for the treatment of food to preserve them and irradiation treatment of food is one of them. It is the most common and the most harmless method for the food preservation as it does not alter the necessary micronutrients of food materials. Although irradiated food doesn’t cause any harm to the human health but still the quality assessment of food is required to provide consumers with necessary information about the food. ESR spectroscopy is the most sophisticated way to investigate the quality of the food and the free radicals induced during the processing of the food. ESR spin trapping technique is useful for the detection of highly unstable radicals in the food. The antioxidant capability of liquid food and beverages in mainly performed by spin trapping technique.
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.

Phenomics assisted breeding in crop improvementIshaGoswami9
As the population is increasing and will reach about 9 billion upto 2050. Also due to climate change, it is difficult to meet the food requirement of such a large population. Facing the challenges presented by resource shortages, climate
change, and increasing global population, crop yield and quality need to be improved in a sustainable way over the coming decades. Genetic improvement by breeding is the best way to increase crop productivity. With the rapid progression of functional
genomics, an increasing number of crop genomes have been sequenced and dozens of genes influencing key agronomic traits have been identified. However, current genome sequence information has not been adequately exploited for understanding
the complex characteristics of multiple gene, owing to a lack of crop phenotypic data. Efficient, automatic, and accurate technologies and platforms that can capture phenotypic data that can
be linked to genomics information for crop improvement at all growth stages have become as important as genotyping. Thus,
high-throughput phenotyping has become the major bottleneck restricting crop breeding. Plant phenomics has been defined as the high-throughput, accurate acquisition and analysis of multi-dimensional phenotypes
during crop growing stages at the organism level, including the cell, tissue, organ, individual plant, plot, and field levels. With the rapid development of novel sensors, imaging technology,
and analysis methods, numerous infrastructure platforms have been developed for phenotyping.
The use of Nauplii and metanauplii artemia in aquaculture (brine shrimp).pptxMAGOTI ERNEST
Although Artemia has been known to man for centuries, its use as a food for the culture of larval organisms apparently began only in the 1930s, when several investigators found that it made an excellent food for newly hatched fish larvae (Litvinenko et al., 2023). As aquaculture developed in the 1960s and ‘70s, the use of Artemia also became more widespread, due both to its convenience and to its nutritional value for larval organisms (Arenas-Pardo et al., 2024). The fact that Artemia dormant cysts can be stored for long periods in cans, and then used as an off-the-shelf food requiring only 24 h of incubation makes them the most convenient, least labor-intensive, live food available for aquaculture (Sorgeloos & Roubach, 2021). The nutritional value of Artemia, especially for marine organisms, is not constant, but varies both geographically and temporally. During the last decade, however, both the causes of Artemia nutritional variability and methods to improve poorquality Artemia have been identified (Loufi et al., 2024).
Brine shrimp (Artemia spp.) are used in marine aquaculture worldwide. Annually, more than 2,000 metric tons of dry cysts are used for cultivation of fish, crustacean, and shellfish larva. Brine shrimp are important to aquaculture because newly hatched brine shrimp nauplii (larvae) provide a food source for many fish fry (Mozanzadeh et al., 2021). Culture and harvesting of brine shrimp eggs represents another aspect of the aquaculture industry. Nauplii and metanauplii of Artemia, commonly known as brine shrimp, play a crucial role in aquaculture due to their nutritional value and suitability as live feed for many aquatic species, particularly in larval stages (Sorgeloos & Roubach, 2021).

Nutraceutical market, scope and growth: Herbal drug technologyLokesh Patil
As consumer awareness of health and wellness rises, the nutraceutical market—which includes goods like functional meals, drinks, and dietary supplements that provide health advantages beyond basic nutrition—is growing significantly. As healthcare expenses rise, the population ages, and people want natural and preventative health solutions more and more, this industry is increasing quickly. Further driving market expansion are product formulation innovations and the use of cutting-edge technology for customized nutrition. With its worldwide reach, the nutraceutical industry is expected to keep growing and provide significant chances for research and investment in a number of categories, including vitamins, minerals, probiotics, and herbal supplements.
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.

13. Transgenic mice can be produced with high
capacity vectors
• Generally done by microinjection of numerous genes
contained in a YAC
• Production of mice that can produce human
antibodies is one notable example
14. Transgenic mice/animal: applications
• Transgenic models for Alzheimer disease, amyotrophic lateral
sclerosis, Huntington disease, arthritis, muscular dystrophy,
tumorigenesis, hypertension, neurodegenerative disorders,
endocrinological dysfunction, coronary disease, etc.
• Using transgenic mice as test systems (e.g., protein [CFTR] secretion
into milk, protection against mastitis caused by Staphylococcus
aureus using a modified lysostaphin gene)
• Conditional regulation of gene expression (tetracycline-inducible
system in Fig. 21.19)
• Conditional control of cell death (used to model and study organ
failure; involves the organ-specific engineering of a toxin receptor
into the mice and then addition of the toxin to kill that organ)
15. Another Transgenic mouse application:
Marathon Mice
Instead of improving times by fractions of a second, the
genetically enhanced “marathon” mice (above, on the
treadmill in San Diego) ran twice as far and nearly twice
as long as ordinary rodents. The peroxisome
proliferator-activated receptor (PPAR-delta) gene was
overexpressed in these transgenic mice. For details, see
http://www.salk.edu/otm/Articles/PLoSBiology_Octobe
r2004.pdf
Dr. Ron Evans and one of his genetically engineered
“marathon” mice. The enhanced PPAR-delta activity
not only increased fat burning, but transformed
skeletal muscle fibers, boosting so-called "slow-
twitch" muscle fibers, which are fatigue resistant,
and reducing 'fast-twitch' fibers, which generate
rapid, powerful contractions but fatigue easily.
18. And now there is pet cloning for a “small” fee…
Nine-week-old "Little Nicky" peers out from
her carrying case in Texas. Little Nicky,
a cloned cat, was sold to its new owner
by Genetic Savings and Clone for $50,000
in December 2004.
August 07, 2008 | Bernann McKinney with one of
the 5 puppies cloned from Booger, her late pet
pit bull. It cost her $50,000. When Booger was
diagnosed with cancer, a grief-stricken McKinney
sought to have him cloned -- first by the now-
defunct Genetic Savings and Clone, and then by
South Korean company RNL Bio.
19. Transgenic cattle, sheep,
goats, and pigs
• Using the mammary gland as a
bioreactor (see adjacent figure)
• Increase casein content in milk
• Express lactase in milk (to remove
lactose)
• Resistance to bacterial, viral, and
parasitic diseases
• Reduce phosphorous excretion
20. Table 21.2 Some human proteins expressed in
the mammary glands of transgenic animals

• Antithrombin III (the first transgenic animal drug, an
anticlotting protein, approved by the FDA in 2009)
21. “Enviropigs”
• Transgenic pigs expressing the
phytase gene in their salivary glands
• The phytase gene was introduced via
DNA microinjection and used the
parotid secretory protein promoter
to specifically drive expression in the
salivary glands
• Phytate is the predominant storage
form of phosphorus in plant-based
animal feeds (e.g., soybean meal)
• Pigs and poultry cannot digest
phytate and consequently excrete
large amounts of phosphorus
• “Enviro-pigs” excrete 75% less
phosphorus
• Microinjected an E. coli phytase
gene under the control of a mouse
parotid secretory protein promoter
EnviropigTM an environmentally friendly
breed of pigs that utilizes plant
phosphorus efficiently.

transgenic chickens by
transfection of isolated
blastoderm cells
• Resistance to viral, bacterial,
and coccidial diseases
• Better feed efficiency
• Lower fat and cholesterol
levels in eggs
• Better meat quality
• Eggs with pharmaceutical
proteins in them
23. Transgenic fish
• Genes are introduced into fertilized eggs by DNA microinjection or
electroporation
• No need to implant the embryo; development is external
• Genetically engineered for more rapid growth using the growth hormone
gene (salmon, trout, catfish, tuna, etc.)
• Genetically engineered for greater disease resistance
• Genetically engineered to serve as a biosensor for water pollution
• Genetically engineered for a novel pet (Glofish-see http://glofish.com/)
24. Transgenic fish (more detail)
• Salmon were genetically engineered for more rapid growth using the growth
hormone gene under the control of the ocean pout antifreeze protein gene
promoter and 3’ untranslated region (currently under FDA consideration)
• Madaka fish were genetically engineered to serve as biosensors for
environmental pollutants (e.g., estrogens) by using an estrogen-inducible
promoter (the vitellogenin promoter) to control expression of the GFP gene
