Dr. Doris Taylor presents "Building New Hearts: Regenerative Medicine Becomes a Reality" at the Banff Transplant Pathology meeting in Vancouver October 5, 2015.
Objective: To evaluate the results of the effect of nebivolol on tibial bone defect and graft application in new bone development in the rat.
Study Design: Thirty Wistar albino rats were divided into 3 groups. In the Control group, tibia bone defect was created without any treatment. In the Defect+ Graft group, allograft treatment was performed by forming a 6 mm tibial bone defect. In the Defect+Graft+ Nebivolol group, alloplastic bone graft was placed in the calvarial bone defect and then nebivolol (0.34 mg/mL solution/day) treatment was intraperitoneally applied for 28 days.
Results: Histopathological examination revealed inflammation in the defect area, congestion in the vessels, degeneration in collagen fibers, and an increase in osteoclast cells. There was an increase in inflammation and blood vessel structure in graft application, and osteoblastic activity matrix formation after reorganization nebivolol application in collagen fibers. Osteonectin expression was positive in the collagen fiber and matrix, starting in the Graft group, in osteoblasts, whereas in the Nebivolol group, osteoblasts increased in osteocytes and new bone formation.
Conclusion: Nebivolol is thought to have a positive effect on osteoinductive bone growth factors and contribute to the cell-matrix interaction, in addition to the supporting effect of the graft with its antioxidative effect.

MRI rat organ Assessment under recurrent Interferon administrationtheijes
This study aims to assess serial and transverse quantitative Magnetic Resonance Imaging (MRI) in four rat groups using different doses of a formulation based on the combinations of IFN alpha 2b and gamma. Axial and coronal T1, T2 and Diffusion MRI images have been performed in order to follow up morphological and tissue texture changes in the rat brain, cerebellum, spinal cord and kidney. As a result, no morphological changes have been observed during 28 days in any of the four groups including the placebo. Yet, doses until 15 times were bigger than the therapeutic dose. This MRI studies is robust and complementary evidence that the pharmaceutical formulation mixing in the same vial IFNs alpha2b and gamma is safe. For the first time, results of a longitudinal MRI study in rats based on the effects of this pharmacological combination are reported.

Genotoxicity Evaluation of Polystyrene Membrane with Collagen and Norbixin by...inventionjournals
The biocompatible membranes are widely applied in the medical field in order to stimulate tissue repair. The biological principle of this type of treatment is the repair and guided regeneration. In the literature, there are few reports of studies evaluating the effects and biological properties of norbixin in animal tissues. Thus, the present study was to evaluate the effect of polystyrene membrane with collagen and norbixin, through the micronucleus test and comet assay in rats, as part of the recommended test battery to evaluate the mutagenic potential. The research project was approved by CEP / FACID Protocol 069/2014. For this study, 15 rats were divided into 3 groups were used: A - the membrane was introduced into the peritoneum of the animals through a laparotomy; B - received cyclophosphamide at a dose of 50mg / kg intraperitoneally; C - were performed only one laparotomy. A peripheral blood sample was collected from the animals for conducting Comet assay and 72 hours after the start of the experiment were euthanized. It was collected bone marrow material of each rat to perform the micronucleus test. In conclusion, through the tests, the membrane is not genotoxic

The use of adipose tissue transfer in plastic and reconstructive surgery is not new and has been studied for more than a century but problems such as unpredictability in results and a low rate of graft survival due to partial necrosis were always among major concerns. However, emerging information regarding the potential of adipose derived stem cells, new methods of cell extraction, graft preparation and injection techniques have increased the popularity of fat transfer and the efforts toward development of cell based therapies for various diseases from Adipose Derived Stem Cells (ADSC’s) and Stromal Vascular Fraction (SVF) of the adipose tissue. Although the mechanism of action of those stem cells is not fully known, their paracrine activities and transformation to various cell types can be responsible for reported clinical outcomes [1,2]. Many clinicians and researchers report better outcomes in fat grafting upon addition of SVF cells [1,2]. This study aims to investigate the long-term (3 years) safety of Antria’s cell preparation process utilizing a digestive enzyme in SVF assisted fat grafting. The outcomes of this study was utilized to conduct further safety and efficacy studies to obtain regulatory and marketing approval for a novel SVF extraction method in the US.

ABSTRACT Similar to the disease affecting humans, osteoarthritis (OA) is a painful musculoskeletal condition affecting 20% of the adult canine population. Several solutions have been proposed, but the results achieved to date are far from being satisfactory. New approaches, such as intra-articular delivery of cells (including mesenchymal stromal cells), have been proposed. Among the many sources, the adipose tissue is considered very promising. We evaluated the safety, feasibility, and efficacy of a single intra-articular injection of autologous and micro-fragmented adipose tissue (MFAT) in 130 dogs with spontaneous OA. MFAT was obtained using a minimally invasive technique in a closed system and injected in the intra- and/or peri-articular space. Clinical outcomes were determined using orthopedic examination and owners’ scores for up to 6 months. In 78% of the dogs, improvement in the orthopedic score was registered 1 month after treatment and continued gradually up to 6 months when 88% of the dogs improved, 11% did not change, and 1% worsened compared with baseline. Considering the owners’ scores at 6 months, 92% of the dogs significantly improved, 6% improved only slightly, and 2% worsened compared with baseline. No local or systemic major adverse effects were recorded. The results of this study suggest that MFAT injection in dogs with OA is safe, feasible, and beneficial. The procedure is time sparing and cost-effective. Post injection cytological investigation, together with the clinical evidence, suggests a long-term pain control role of this treatment. The spontaneous OA dog model has a key role in developing successful treatments for translational medicine. STEM CELLS TRANSLATIONAL MEDICINE 2018;00:1–10
THE company behind an innovative product “that is revolutionising how vets are able to treat tendon and ligament injuries” is planning a seminar in May to showcase treatment options, techniques, the science and clinical data.
Lipocast Biotech UK brought Lipogems Equine and Canine to the UK market and said the treatment had “grown exponentially” in 2017 due to success accredited veterinary surgeons are seeing in equine and canine patients. Use in international veterinary schools is adding to positive testaments of the treatment’s capability, the firm said.
A database of studies is being compiled for both equine and canine patients, with Tim Watson, of Waterlane Equine Vets, Gloucestershire, leading collection of the equine data.
Lipogems offers, says Lipocast, a rapid and cost-effective means of harvesting mesenchymal stromal cells (MSCs), helping vets treat tendon and ligament injuries and manage degenerative joint diseases.
Lipogems harnesses, says Lipocast Biotech, the potential of pericyte cells that surround capillaries. Following tissue injury, pericytes detach from the capillaries and gradually convert into activated MSCs and begin the process of orchestrating tissue repair. The Lipogems technique delivers MSCs from pericytes in adipose tissue that are collected by liposuction, flushed and processed using gentle mechanical disruption.
These MSCs understand the nature of the injury into which they are injected and then stimulate and coordinate numerous biological processes for effective healing. For equine veterinary surgeons, the procedure can be performed stable-side in 40 minutes, with no additional culture or laboratory time is required.
Lipocast Biotech UK has now announced the inaugural Lipogems Regenerative Medicine Seminar will be held on 16 May in Cirencester, Gloucestershire. The seminar, which offers five CPD hours, is free of charge, and leading vets will give lectures about the future of regenerative medicine and the science behind the technology, with case-based evidence and procedure demonstrations presented.
Dr Watson said: “Lipogems is an easy technique that can be performed at the patient's side and enables prompt treatment for a wide range of common orthopaedic conditions affecting horses and ponies. The results are superior to other regenerative therapies currently used.”

Mammalian MSC from Selected Species: Features and Applications
Christiane Uder, Sandra Br€uckner, Sandra Winkler, Hans-Michael Tautenhahn,†‡ Bruno Christ†*
Mesenchymal stromal/stem cells (MSC) are promising candidates for cellular therapy of different diseases in humans and in animals. Following the guidelines of the International Society for Cell Therapy, human MSC may be identified by expression of a specific panel of cell surface markers (CD1051, CD731, CD901, CD34-, CD14-, or CD11b-, CD79- or CD19-, HLA-DR-). In addition, multiple differentiation potential into at least the osteogenic, adipogenic, and chondrogenic lineage is a main criterion for MSC definition. Human MSC and MSC of a variety of mammals isolated from different tissues meet these criteria. In addition to the abovementioned, they express many more cell surface markers. Yet, these are not uniquely expressed by MSC. The gross phenotypic appearance like marker expression and differentiation potential is similar albeit not identical for MSC from different tissues and species. Similarly, MSC may feature different biological characteristics depending on the tissue source and the isolation and culture procedures. Their versatile biological qualities comprising immunomodulatory, anti-inflammatory, and proregenerative capacities rely largely on the migratory and secretory capabilities of MSC. They are attracted to sites of tissue lesion and secrete factors to promote self-repair of the injured tissue. This is a big perspective for clinical MSC applications in both veterinary and human medicine. Phase I/II clinical trials have been initiated to assess safety and feasibility of MSC therapies in acute and chronic disease settings. Yet, since the mode of MSC action in a specific disease environment is still unknown at large, it is mandatory to unravel the response of MSC from a given source onto a specific disease environment in suitable animal models prior to clinical applications.
Adipose Tissue and Mesenchymal Stem Cells: State of the Art and Lipogems® Technology Development
Carlo Tremolada1 & Valeria Colombo1 & Carlo Ventura2
Abstract Inthepastfewyears,interestinadiposetissueasan ideal source of mesenchymal stem cells (MSCs) has increased. These cells are multipotent and may differentiate in vitro into several cellular lineages, such as adipocytes, chondrocytes, osteoblasts, and myoblasts. In addition, they secrete many bioactive molecules and thus are considered Bmini-drugstores.^ MSCs are being used increasingly for many clinical applications, such as orthopedic, plastic, and reconstructive surgery. Adipose-derived MSCs are routinely obtained enzymatically from fat lipoaspirate as SVF and/or may undergo prolonged ex vivo expansion, with significant senescence and a decrease in multipotency, leading to unsatisfactory clinicalresults.Moreover, these techniquesare hampered by complex regulatory issues. Therefore, an innovative technique (Lipogems®; Lipogems International SpA, Milan, Italy) was developed to obtain microfragmented adipose tissue with an intact stromal vascular niche and MSCs with a high regenerative capacity. The Lipogems® technology, patented in 2010 and clinically available since 2013, is an easyto-use system designed to harvest, process, and inject refined fat tissue and is characterized by optimal handling ability and a great regenerative potential based on adipose-derived MSCs. In this novel technology, the adipose tissue is washed, emulsified, and rinsed and adipose cluster dimensions gradually are reduced to about 0.3 to 0.8 mm. In the resulting
Lipogems® product, pericytes are retained within an intact stromal vascular niche and are ready to interact with the recipient tissue after transplantation, thereby becoming MSCs and starting the regenerative process. Lipogems® has been used in more than 7000 patients worldwide in aesthetic medicineandsurgery,aswellasinorthopedicandgeneralsurgery, with remarkable and promising results and seemingly no drawbacks. Now, several clinical trials are under way to supporttheinitialencouragingoutcomes.Lipogems®technology is emerging as a valid intraoperative system to obtain an optimal final product that may be used immediately for regenerative purposes.

Background: Adipose-derived mesenchymal stromal cells (Ad-MSCs) are a promising tool for advanced cell-based therapies. They are routinely obtained enzymatically from fat lipoaspirate (LP) as SVF, and may undergo prolonged ex vivo expansion, with significant senescence and decline in multipotency. Besides, these techniques have complex regulatory issues, thus incurring in the compelling requirements of GMP guidelines. Hence, availability of a minimally manipulated, autologous adipose tissue would have remarkable biomedical and clinical relevance. For this reason, a new device, named Lipogems® (LG), has been developed. This ready-to-use adipose tissue cell derivate has been shown to have in vivo efficacy upon transplantation for ischemic and inflammatory diseases. To broaden our knowledge, we here investigated the angiogenic and anti-inflammatory properties of LG and its derived MSC (LG-MSCs) population.

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).
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.

BREEDING METHODS FOR DISEASE RESISTANCE.pptxRASHMI M G
Plant breeding for disease resistance is a strategy to reduce crop losses caused by disease. Plants have an innate immune system that allows them to recognize pathogens and provide resistance. However, breeding for long-lasting resistance often involves combining multiple resistance genes
This presentation explores a brief idea about the structural and functional attributes of nucleotides, the structure and function of genetic materials along with the impact of UV rays and pH upon them.
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.

4. Regenerative Medicine
Depends what do we aim for…
1) Recreation of new organs? NO
2) Regeneration of some tissues? MAYBE
3) Reduce inflammation and pain? YES
Prometheus will have to wait…
improve the quality of life
6. Regenerative Medicine –
modification of our approach
• Stem cells from bone marrow or adipose tissue needs
colture (12-15 days). OK for IV & heterologous use
• For arthropaties we looked for a product that has the
same capability but do not need colture. OK only for
autologous and local administration!!!
7. Device and procedure
Ideally we looked for:
• A disposable device for liposuction and
processing of adipose tissue
• The entire procedure is done in one session
• Reduction of adipose tissue clusters size,
eliminating pro-inflammatory oily and blood
residuals
• Closed aseptic system, minimal manipulation,
enzyme-free
8. • To verify clinical safety and efficacy of the device for
advanced therapy
• Quality and quantitative evaluation of the device’s
outcomes
Patient Selection
• 109 dogs (236 affected joints)
• From 8 months to 14 years old
• Single or multiple arthropaties, otherwise
healthy
Aim
Canine arthropaties - safety and efficacy of
microfragmented adipose tissue treatment
10. Canine Osteoarthrosis: safety and efficacy of
microfragmented adipose tissue treatment
Orthopedic examination
• Complete check up (CBC + biochemistry)
• RX (3/4 projections)
In case of severe DJD/OA:
• MRI
• Synovial fluid analisys
• IA treatment
Outcomes assesment:
• Control at 1, 3 and 6 months: clinical examination, RX and MRI
• Maximum of 24 months of fully documented follow-up
• Post mortem joint histology

Cytologic assessment
• In 92% of the treated articulations synovial fluid analysis showed improvement
Results
Safety & feasibility
• hematology and imaging diagnostics results after administration showed no
worsening of previous clinical status and no onset of new pathologies
• intra-articular injection showed no difficulty and no irreversible adverse
reaction (2 cases of septic arthritis – 1.8%)
Safety, feasibility and clinical results of treatment in
109 dogs with arthropaties
23. Results
Histologic assessment
• Microscopic changes characteristic of osteoarthrosis
• Minimal inflammatory changes in bone marrow and joint synovial membrane
• Remnants of the injected material in clusters (large eosinophilic cells with
vacuoles, empty adipocytes, stromal cells, high numbers of MSCs and pericytes,
abundant microvascular endothelial cell)
Safety, Feasibility and clinical results of treatment in
109 dogs with arthropaties
AdipocytesStromal cells Reticular stroma
24. Conclusions
1. Adipose tissue contain, adipocytes and heterogeneous population of
hematopoietic cells, pericytes, endothelial cells and progenitors, and
stromal/stem cells. IA treatment with these elements is safe and feasible
in dogs with OA.
2. Our clinical results supports in vitro reports describing Lipogems as an
effective preparation of fat-derived tissue that retains either per se, or in
its embedded MSCs content, the capacity to induce vascular stabilization
and inhibit several macrophage functions involved in inflammation.
3. Further histological investigation of treated joints is needed in order to
better understand the underlying mechanisms, however, the long term
survival of Lipogems clusters within the treated joints, may explain the
long term efficacy of the treatment
4. Lipogems preparation from dog’s adipose tissue can be easily expanded in
culture and its properties are not altered by cryoconservation
