<p>The pool assessment tool and low osteoporosis rate reminded us of the difficulty for the old's bone health. To better guarantee more comprehensive bone health, we tried to achieve an effective Calcium supplement method. We analyzed the current way and relevant health care products market. We came up with some questions and existed difficulty: </p><ol>
 +
<li>Patients usually forget to take supplements, especially for the old. </li>
 +
<li>Calcium absorption rate drops as the amount of calcium intake increases.</li> </ol>
 +
<p>Current market is in urgent need of a supplement method that ensures a high calcium absorption rate over a long period of time. This will avoid frequent intake of a large amount of supplement pills and the precipitation of calcium oxalate. We decided to <a href="/Team:Fudan/Design">design</a> a <b>high and sustainable calcium absorption nutrition</b>. </p></div>

                    However, the currently popular calcium supplement method on the market is either to adjust diet or to consume a lot of calcium supplementing pills. For the elderly, they suffer from poor memory or neglect the importance of calcium pills, often forgetting to consume the supplement; for children, they often refuse to take calcium pills or to maintain some diet high in calcium, thus requiring the "liquid calcium" method to ensure sufficient calcium intake.

<p>We discussed with Professor Lin, who is engaged in prokaryotic expression work at the Fudan University Academy of Sciences. The concept of quorum sensing system described was proposed by Fudan 2019. To help engineered bacteria be competitive enough in the intestine, MccB17 needed better expressed. We thought about using the high-copy plasmids to express MccB17, but they are more challenging to regulate and respond sensitively and extensively to increase engineered bacteria's expression burden.<br/>

    <p>We collaborate with team TJU held an online summer camp for high school students. The activity lasted for two days, and a total of nearly 40 students ranging from grades 9 to 12 participated in it. In the event, we introduced to them the relevant principles and concepts of synthetic biology and shared the concept of iGEM as well as our project. </br>

This year team SCU-China's program is related to fermentation production. They plan to show the different fermentation processes of traditional flour-made food from all over China. Similar to our project, we both focus on nutrition and diet. Some members of our team provided SCU-China with photographs and instructions of flour specialties in their hometown.</br>

  <h4>Model</h4>
+
<p>We establish two models: quorum sensing process and Kill Switch. We refer to the model and data of 2019Fudan team and use the random process to describe it more clearly to model the quorum sensing process in stages and levels. In the kill switch section, we use the 19BNU team’s data, improve the logistic equation, adjust the promoter properties, and make a sensitivity analysis. We can see good results through it. </p>
+
<p>In the quorum sensing part, we used the Gillespie algorithm in random simulation to simulate the macro and micro levels’ physiological processes. It expresses luxI and luxR genes at the micro-level and produces dimers before the population reaches a certain size. At the macro level, Escherichia coli keeps proliferating, excreting antimicrobial peptides, and colonizing the intestinal tract during this process. When the population number is sufficiently large, the short calc-absorbing peptide and the regulation system begin to express. In contrast, the antimicrobial peptide is expressed but cannot be discharged so that the bacterial number can achieve dynamic stability.
+
</p>
+
  <h4>Kill switch</h4>
+
<p>We contacted Mr. Feng in BNU, a member of 19BNU-China and very experienced in kill switches, discussing the kill switch and safety issue of antibiotics resistance gene design. </p>
+
  
<p>We doubted whether the glucose-starvation promotor (BBa_K3036003 from 19BNU-China) would be a suitable response system for our kill switch and hope to obtain their plasmids as a control group directly to save time for constructing it from the beginning.
+
<div class="column full_size"><div class="highlight decoration_background decoration_A_top">
Mr. Feng didn’t consider glucose concentration as a distinct signal to trigger glucose response that existed both inside and outside the body. The difference between the two conditions was not very significant. And he also recommended we search some literature on toxin/antitoxin systems. They probably were ideal candidates for carrying eliminating function.</p>
+
<p>We designed a peptide (CaAP) containing a series of short peptides that can promote calcium absorption. We let probiotics express and secrete this peptide in the intestine to promote calcium absorption in the intestine.</p>
<p>After search the advantages of the toxin/antitoxin system, we decided to undergo an overhaul of our kill switch. This consultation helped us summarize the idea of designing a kill switch that kill switch circuit can be divided into two core components: judging whether bacteria leave the set condition and the other component to kill the bacteria when it leaves the set condition. </p>
+
<p>Antibiotics resistance genes encoded on a plasmid can transfer to the host’s intestinal flora and hurries the development of antibiotic-resistant strains. To improve our product’s safety factor, we wanted to insert our genetic circuits into the genome to inhibit the horizontal transfer. Mr. Feng told us that verifying genome insertion in experiments would take a significant amount of time and was unlikely to be done within a few months. Using plasmids in the experimental stage is still a preferable way. He commended that multi-copy insertion could be designed as the final form of the product.

  <p>Prof. Lin suggested us to use low-copy plasmids to reduce the expression burden of engineered bacteria. We tried to keep the main part of MccB17 (McbABCD) a relatively low expression and high express the immune part (McbEFG) to achieve high secretion of MccB17.</p></div></div>

    <p><b>Educate the old through younger generation.</b></p>
 
<p>Educating the elderly helps the old keep health and protects them from fraud and mis-information. We used a previous unexplored education approach to educate biologic knowledge to the old. Our main strategy is educating the younger generation and instructing them how to educate their grandparents. Compared with traditional education strategies, our approach offers emotional support from the younger generation and is comfortable for the old. In countries like Japan, Korea, Singapore and China, where the bond between grandparents and grandkids is incredibly tight, our approach is undoubtedly effective. </br>
 
To educate the youth, we have held online summer camps for high school students to pass on aged care, in addition to synthetic biology which we have been teaching in the past several years. We developed an online audio course on basic biology knowledge, which could been listened by both the youth and the old. </p>
 
<p>In addition, we combined osteoporosis prevention with traditional Chinese art Xiangsheng, and taught it to the old living in a nursing home (we self as the youth). Also, we wrote Xiàng Sheng (a popular traditional art in China) and other outreach materials for people to use. In summary, we made brave and compelling attempts to implement science communication between the younger generation and the long-neglected social communities - the old.</p>

<b>1.Commercial consult.</b> We contacted factories about our product's cost, more specifically, about the cost of producing pills from lab benches to packages ready for the market.We scheduled several in-person and online appointments with professional investors in the biochemical industry and corresponded with them back and forth to polish our business plan. We also obtained a letter of intent from them, paving ways for future collaboration. Besides, we asked for advice from peers in the Fudan school of management about our marketing strategies and shaped our business plan to target our potential users more effectively.</p>

<p><b>2.CaAass developing.</b> To obtain more professional feedback and get our projects wider public known, we participated in the Fanhai Bei innovation competition and won a third-class prize. According  the judges' feedback, we modified our business model and found that older people in China lacked an easy method to assess their calcium status. Therefore, we developed our Measurement project CaAss to provide a solution for the old people to measure their blood calcium status in a portable way. <a href="https://2020.igem.org/Team:Fudan/Measurement"> Click here to see more details</a></p>

This consultation helped us summarize the idea of designing a kill switch that kill switch circuit can be divided into two core components: judging whether bacteria leave the set condition and the other component to kill the bacteria when it leaves the set condition. </p>

                    However, the currently popular calcium supplement method on the market is either to adjust diet or to consume a lot of calcium supplementing pills. For the elderly, they suffer from poor memory or neglect the importance of calcium pills, often forgetting to consume the supplement; for children, they often refuse to take calcium pills or to maintain some diet high in calcium, thus requiring the "liquid calcium" method to ensure sufficient calcium intake.

<p>Antibiotics resistance genes encoded on a plasmid can transfer to the host’s intestinal flora and hurries the development of antibiotic-resistant strains. To improve our product’s safety factor, we wanted to insert our genetic circuits into the genome to inhibit the horizontal transfer. Mr. Feng told us that verifying genome insertion in experiments would take a significant amount of time and was unlikely to be done within a few months. Using plasmids in the experimental stage is still a preferable way. He commended that multi-copy insertion could be designed as the final form of the product.

<p>Educating the elderly helps the old keep health and protects them from fraud and mis-information. We used a previous unexplored education approach to educate biologic knowledge to the old. Our main strategy is educating the younger generation and instructing them how to educate their grandparents. Compared with traditional education strategies, our approach offers emotional support from the younger generation and is comfortable for the old.In addition, we combined osteoporosis prevention with traditional Chinese art Crosstalk, and taught it to the old living in a nursing home. In summary, we made brave and compelling attempts to implement science communication between the younger generation and the long-neglected social communities - the old.</p>
                <ol>

<p>To educate the youth, we held online summer camps for high school students to pass on aged care, in addition to synthetic biology which we have been teaching in the past several years. We developed an online audio course on basic biology knowledge, which could been listened by both the youth and the old. </p>

human practices

Combine World with Bone health

Integrated Human Practice connects the world and our project. Inspired by the bone disease of old people, our project centers on osteoporosis and calcium absorption to constitute Bone Appetite. We constantly improve our design and execution by the feedbacks of public engagement, to make sure our project is good and responsible for the old, the whole human, the world. We compete for both the Silver Medal criterion #3 and the Best Integrated HP prize with this page.

Outline and Overview

Integration of Human Practice and Bone Appetide Project
Figure 1. Integration of Human Practice and Bone Appetide project

Social surveys and Public engagement are the core of our Integrated Human Practices. When we gained our inspiration for bone health, we turned to social surveys and the critical stakeholders for the priority. Besides, picture and design our whole project according to their feedbacks.

Social Surveys

Considering the COVID-19 pandemic, our team specially design an online questionnaire to do relevant social surveys. Due to our care about bone health and osteoporosis, we used widely social study to investigate public awareness and dig the potential need. For the old who has a hard availability of smartphone and the Internet, we visit the elderly community and senior home under the premise of keeping enough social distance and well protective measures.

The questionnaire of social surveys
Figure 2. The questionnaire of social surveys

Public general knowledge

The online surveys mainly direct at the people under 60 years old. We analyzed their knowledge of osteoporosis and daily calcium supplement situation. The result showed that the public has a strong awareness of osteoporosis and bone health along with the growing of age. For respondents aged 40 to 60, more than half of them are taking or have taken calcium supplements health care products.

Interviews with old people

We believe the best suitable way to know the awareness message from the old is talking face to face. Connected with the largest student public-service association of Fudan University, we cooperated with “The Home of Elderly” project, which aims at satisfy the need of the old. We interviewed dozens of aged people over 60 years old in a Shanghai elderly community. Then we were surprised by their extremely low awareness of osteoporosis and lack of calcium supplement.




Interview the old in community
Figure 5. Our teammate interview the old in the community

The series of effective surveys provide us the reality of public awareness of calcium supplements and reveal the elderly’s problem. The evidence from the statistics analysis helped us to unearth the education need of the elderly. Specially, we came up with an idea of educating the younger generation and instructing them to educate their grandparents.

Bone health is a serious problem for the old. They have a severe need for Calcium supplements. We wanted to know the current treatment of osteoporosis and everyday health care products for Calcium supplement in this case. We carried our thought to interview several key stakeholders and discuss the method to achieve them. Given the outbreak of the COVID-19 pandemic, we took action mainly in online form.

Online Public Engagement

Dr. Dongying Qiu and Weiying Ren

Deputy Chief Physician of Geriatrics Department, Zhongshan Hospital, Fudan University.

We consulted clinical physicians about the current osteoporosis treatment situation and FRAX (WHO Fracture Risk Assessment Tool), which is considered underestimating the Chinese population’s risk. They provided us plenty of important messages.

First, the consultation rate of osteoporosis was quite low, owing to the old’s low awareness.

Second, different assessment tools match various application scope. Guidelines for the diagnosis and management of primary osteoporosis provided by the Chinese Society of Osteoporosis and Bone Mineral Research are used in the clinic but still has question and limitation.

What’s more, we exhibited our project design and education for older people to them, which gained great admiration. Dr.Qiu shared his own educational experience to instruct us. He suggested we should be careful with our expression, which needs to be scientific.

qiu dongying ren weiying

Dr. Wei Hong

Deputy Chief Physician of Osteoporosis Department, East China Hospital affiliated to Fudan University

Dr. Hong is a professor in the area of osteoporosis who also makes an effort to educate patients. We discussed the design of the assessment tool and how to improve the current treatment and recovery method. Dr.Hong pointed out the self-assessment tool's difficulty because of the lack of a database that big enough. We learned that the community is the most effective way to carry out education and recovery introduction. The direct contact with the old helps continuous supervision of treatment progress.

wei hong

The pool assessment tool and low osteoporosis rate reminded us of the difficulty for the old's bone health. To better guarantee more comprehensive bone health, we tried to achieve an effective Calcium supplement method. We analyzed the current way and relevant health care products market. We came up with some questions and existed difficulty:

  1. Patients usually forget to take supplements, especially for the old.
  2. Calcium absorption rate drops as the amount of calcium intake increases.

Current market is in urgent need of a supplement method that ensures a high calcium absorption rate over a long period of time. This will avoid frequent intake of a large amount of supplement pills and the precipitation of calcium oxalate. We decided to design a high and sustainable calcium absorption nutrition.

Senior home staff and care workers

Xinguang Senior Home, Shanghai

In Xinguang senior home, they have nearly 100 elders aged 60 to 100. We interviewed their staff about the bone health of the old. They reflected several severe fractures caused by osteoporosis and pointed their general bad bone health.

Prof. Jinzhong Lin

School of Life Sciences Fudan University

We discussed with Professor Lin, who is engaged in prokaryotic expression work at the Fudan University Academy of Sciences. The concept of quorum sensing system described was proposed by Fudan 2019. To help engineered bacteria be competitive enough in the intestine, MccB17 needed better expressed. We thought about using the high-copy plasmids to express MccB17, but they are more challenging to regulate and respond sensitively and extensively to increase engineered bacteria's expression burden.

We designed a peptide (CaAP) containing a series of short peptides that can promote calcium absorption. We let probiotics express and secrete this peptide in the intestine to promote calcium absorption in the intestine.

Prof. Lin suggested us to use low-copy plasmids to reduce the expression burden of engineered bacteria. We tried to keep the main part of MccB17 (McbABCD) a relatively low expression and high express the immune part (McbEFG) to achieve high secretion of MccB17.

Collaboration

TJU
SCU

We collaborate with team TJU held an online summer camp for high school students to introduced the relevant principles and concepts of synthetic biology and shared the concept of iGEM as well as our project. More details at /Team:Fudan/Collaborations.

Model

We establish two models: quorum sensing process and Kill Switch. We refer to the model and data of 2019Fudan team and use the random process to describe it more clearly to model the quorum sensing process in stages and levels. In the kill switch section, we use the 19BNU team’s data, improve the logistic equation, adjust the promoter properties, and make a sensitivity analysis. We can see good results through it. More details at /Team:Fudan/Model.

Kill Switch design

We contacted Mr. Feng in BNU, a member of 19BNU-China and very experienced in kill switches, discussing the kill switch and safety issue of antibiotics resistance gene design.

BNU2

We discussed whether the glucose-starvation promotor (BBa_K3036003 from 19BNU-China) would be a suitable response system for our kill switch and hope to obtain their plasmids as a control group directly to save time for constructing it from the beginning. Mr. Feng didn’t consider glucose concentration as a distinct signal to trigger glucose response that existed both inside and outside the body. The difference between the two conditions was not very significant. And he also recommended we search some literature on toxin/antitoxin systems. They probably were ideal candidates for carrying eliminating function.

After search the advantages of the toxin/antitoxin system, we decided to undergo an overhaul of our kill switch. This consultation helped us summarize the idea of designing a kill switch that kill switch circuit can be divided into two core components: judging whether bacteria leave the set condition and the other component to kill the bacteria when it leaves the set condition.

Antibiotics resistance genes encoded on a plasmid can transfer to the host’s intestinal flora and hurries the development of antibiotic-resistant strains. To improve our product’s safety factor, we wanted to insert our genetic circuits into the genome to inhibit the horizontal transfer. Mr. Feng told us that verifying genome insertion in experiments would take a significant amount of time and was unlikely to be done within a few months. Using plasmids in the experimental stage is still a preferable way. He commended that multi-copy insertion could be designed as the final form of the product.

Education

Educate the old through younger generation.

Educating the elderly helps the old keep health and protects them from fraud and mis-information. We used a previous unexplored education approach to educate biologic knowledge to the old. Our main strategy is educating the younger generation and instructing them how to educate their grandparents. Compared with traditional education strategies, our approach offers emotional support from the younger generation and is comfortable for the old.In addition, we combined osteoporosis prevention with traditional Chinese art Crosstalk, and taught it to the old living in a nursing home. In summary, we made brave and compelling attempts to implement science communication between the younger generation and the long-neglected social communities - the old.

To educate the youth, we held online summer camps for high school students to pass on aged care, in addition to synthetic biology which we have been teaching in the past several years. We developed an online audio course on basic biology knowledge, which could been listened by both the youth and the old.

Commercialization analysis

commercialization timeline

We made the market investigations and pitched our commercial plan to potential commercial investors. During these interactions, we improved our existing design for CaAP, and we came up with the CaAsst test strip product, which later got support by our pilot experiments. More details at /Team:Fudan/Entrepreneurship.

1. Commercial consult. We contacted factories about our product's cost, more specifically, about the cost of producing pills from lab benches to packages ready for the market. Wescheduled several in-person and online appointments with professional investors in the biochemical industry and corresponded with them back and forth to polish our business plan. We also obtained a letter of intent from them, paving ways for future collaboration. Besides, we asked for advice from peers in the Fudan school of management about our marketing strategies and shaped our business plan to target our potential users more effectively.

2. CaAsst developing. To obtain more professional feedback and get our projects wider public known, we participated in the Fanhai Bei innovation competition and won a third-class prize. According the judges' feedback, we modified our business model and found that older people in China lacked an easy method to assess their calcium status. Therefore, we developed our Measurement project CaAsst to provide a solution for the old people to measure their blood calcium status in a portable way. More details at /Team:Fudan/Measurement

Summary

Our project focus on reducing the impact of osteoporosis, trying search the way to making world better.

  1. Analyzed the whole ages surveys to investigate public awareness and the current suffering situation of the old people.
  2. Interviewed various stakeholders, including clinicians, professors and care workers to gather the limits of current treatments and used these feedbacks to design our project.
  3. Connected with members of 19BNU and 19Fudan to gain their valuable insights and outline our wet lab experiments.
  4. Made the market investigations and pitched our commercial plan to potential commercial investors.
  5. In order to educate the aged people more effectively, we communicated with care workers and created instructional materials on care given.

During these interactions, we improved our existing design for CaAP, and we came up with the CaAsst test strip product, which later got support by our pilot experiments.Our team successfully integrated Human Practice to design and improve our Bone Appetite project.
