Molecular Imprinting and Chitosan for Targeted Treatments (Drug Delivery)
Molecular Imprinting: A Game-Changer in Drug Delivery
Molecular imprinting is a cutting-edge technology that has gained significant attention for its ability to create intelligent polymer materials with specific recognition capabilities for target molecules. These materials, known as molecularly imprinted polymers (MIPs), are synthesized by polymerizing functional monomers around a template molecule, which is then removed, leaving behind cavities that are complementary in shape, size, and chemical functionality to the template. This process endows MIPs with predetermined recognition ability, making them highly selective for the target molecule.MIPs offer numerous advantages over traditional drug delivery systems. They are highly stable, both thermally and chemically, and can withstand harsh conditions that would degrade other materials. Additionally, MIPs are cost-effective, as they can be easily synthesized and are reusable. Their high selectivity and affinity for the target molecule enable them to effectively control drug release, making them ideal for creating high-performance drug delivery systems.

Harnessing the Power of Chitosan

Chitosan, derived from chitin, is a versatile amino-polysaccharide that has gained considerable attention in the field of drug delivery due to its biocompatibility and biodegradability. Chitosan is a linear polysaccharide composed of randomly distributed β-(1-4)-linked D-glucosamine and N-acetyl-D-glucosamine units. Its functional groups, such as amino and hydroxyl groups, allow for structural modifications, making it a valuable resource for preparing MIPs.Chitosan-based MIPs offer several advantages over traditional MIPs. They are more biocompatible and biodegradable, reducing the risk of adverse reactions and long-term accumulation in the body. Additionally, chitosan's cationic nature enables it to interact with negatively charged molecules, expanding its applications in drug delivery.Chemical modifications of chitosan, such as carboxymethylation, hydroxypropylation, and quaternization, can enhance its solubility and properties, further expanding its applications in various fields, including medicine. For instance, carboxymethyl chitosan has improved water solubility and mucoadhesive properties, making it an ideal candidate for colon-specific drug delivery.

Targeting Colorectal Cancer with 5-Fluorouracil

5-Fluorouracil (5-FU) is a potent chemotherapy drug for colorectal cancer, but its limitations include rapid metabolism and low bioavailability. To address these challenges, researchers are focusing on developing oral colon-specific delivery systems for 5-FU. By combining molecular surface imprinting with pH-sensitive and time-delayed release mechanisms, a novel delivery system is being designed to enhance the efficacy and safety of colorectal cancer treatment.The OCDDS for 5-FU is based on the concept of exploiting the unique physiological conditions of the colon, such as its lower pH and the presence of specific enzymes, to achieve site-specific drug release. This system typically consists of an enteric coating that protects the drug from premature release in the stomach and small intestine, and a chitosan-based MIP core that selectively releases the drug in the colon.The integration of molecular imprinting and chitosan in the OCDDS offers several advantages. The MIP core provides high selectivity and affinity for 5-FU, ensuring that the drug is released only in the colon. The chitosan matrix enhances the stability and biocompatibility of the system, while its pH-sensitive properties enable site-specific drug release. Additionally, the time-delayed release mechanism ensures that the drug is released over an extended period, maximizing its therapeutic effect while minimizing side effects.Future Prospects: Integrating Molecular Imprinting, Chitosan, and Advanced Drug Delivery SystemsThe integration of molecular imprinting, chitosan, and advanced drug delivery systems holds immense promise for revolutionizing targeted drug delivery.

2024.05.16 14:08 Extension_Band_8138 Your hunger, cravings & satiety anecdotes wanted!

This is a highly exploratory post inspired by some books I delved into recently as well as exfatloss' recent post about satiety (why would salsa and sour cream be such appetite enhancers? What is it about them??).
I guess we sometimes need to engage in knowledge 'fishing expeditions' and just hope some patterns emerge. This is a sub with a lot of first hand experience various food / macro restrictions who pays attention to what they eat and how they feel about it more than the general population.
Please share your accounts of various cravings / satiety experiences while on different restricted diets. It can be something you experience now or have experienced in the past. It can be something you have noticed in your pets or farm animals (we're not that different from them after all!). It can be transient, or something you experience your whole life. I would like to collect these hunge satiety narratives.
Give as much background as you can remember - what was your diet (approx macros, types of food). How long did craving / satiety last? Did you give into it? Does it drive you to overeat / undereat? Did it feel like the mental 'want' was disconected from physical intake (ie. My stomach is distended from overeating, but still crave some more)? How long does the drive to eat / avoid food lasts? What was your energy / mood levels at the time? Do you have any medical conditions that may influence it? Were you taking any drugs or supplements at the time? What is your hunch on why the craving / satiety happened? What are the most delicious things you've ever tasted? If you had them repeatedly, would they lose appeal? What foods feel satisfying? What foods make you not able to take another bite?
To have any chance at patterns emerging, I'd prefer us to stick to natural products driving cravings / satiety or minimally processed foods. For processed food, please indicate the ingredients on it, including any fortification that may apply in your country. The more complex the ingredient list, the harder it will be!
We know so little of how hunger, satiety and cravings work, and yet it is so important. This interplay of 'feelings' ensures an animal (incl we) can meet its energy needs and (more impressively!) get a huge array of chemicals needed to buid and maintain its body structures and keep going a huge number of chemical processes going.
Given access to a variety of (natural) food - hunger, satiety and cravings manage to get this 'procurement' system going to astonishing precision. How?
What things can a body trigger cravings for? Is it just minerals? Macros? Amino acids? Types of fat? When does satiety kick in? Is it driven by energy needs being met? Micro nutrient needs being met? A combination of both? Which macro and which micro nutrient combos? Do other food compounds (e.g. flavonoids, protease inhibitors, anti nutrients) make a difference? Do mildly toxic plant compounds (tannins? Protease inhibitors?) trigger satiety? Can certain macros not be processed corectly into energy without given micro nutrients? Does the body know & try to correct that? How does the body know it has a need for something? How does it turn that need into a sensation of hunger / satiety? How does it know / learn what external food product can meet that need?
PS: I probably need to chip in some examples of my own that have baffled me over the years:
  • fortified white flour (and baked goods made from it!) make me ravenous. I have the worst binges after eating fortified white flour (4500kcal+). Includes plain sourdough bread, croissants, shortbread, etc. Sugar and butter seems to enhance the effect ( ie. Fortified flour Shorbread triggers more eating afterwards than fortified plain white bread). No such effect with either unfortified white flour or whole wheat flour. Fat and sugar make no difference if added to unfortified flour. Experimenting to see why that may be.
  • 8-9 months ago I loved dark chocolate. I had it relatively regularly. Now I simply cannot consume it any more. I regularly develop temporary food likes that in a couple of weeks / months turn into aversions (past loves include brocoli, ice cream, jelly, jaffa cakes and food cooked in tallow).
  • on PSMF diet (protein + veg, no fat, no sugar) I feel no hunger or interest in food. I have done the diet for 6 mths at a time. Satiety is not an issue. The downside is extreme lack of energy, meaning I cannot function at all & lack of sleep.
  • I never crave starch or fat. Only sugar (often) and protein (rare). Eating foods high in salt triggers a craving of sugar.
  • cream + sweetened condensed milk trigger instant satiety.

2024.05.16 13:31 ashudigiroads01 How Concrete Fibers Improve Durability: A Deep Dive into the Concrete Fiber Market

Concrete is a fundamental building material, known for its versatility and strength. However, traditional concrete is not without its weaknesses, particularly in terms of durability and resistance to cracking. Enter concrete fibers – an innovative solution that significantly enhances the performance and lifespan of concrete structures. As the concrete fiber market continues to grow, it's important to understand how these fibers improve durability and why they are becoming a preferred choice in construction.

Understanding Concrete Fibers

Concrete fibers are small, discrete reinforcing elements that are added to the concrete mix. These fibers can be made from a variety of materials including steel, glass, synthetic polymers (such as polypropylene), and natural fibers. Each type of fiber offers unique benefits, but they all share a common purpose: to improve the structural integrity and longevity of concrete.

How Concrete Fibers Enhance Durability

  1. Crack Control and Reduction: One of the primary benefits of concrete fibers is their ability to control and reduce cracking.

Fibers distribute tensile stresses more evenly throughout the concrete, minimizing crack formation and propagation.
  2. Increased Toughness and Flexural Strength: Concrete fibers enhance the toughness and flexural strength of concrete. Toughness is the material's ability to absorb energy and plastically deform without fracturing. Fibers act as a bridge across cracks, allowing the concrete to withstand greater loads and stresses. This makes the concrete more resistant to dynamic loads, impact, and vibration.
  3. Improved Fatigue Resistance: Repeated loading and unloading cycles can cause fatigue in concrete, leading to failure over time. Fibers help in absorbing and redistributing these cyclic loads, thereby improving the fatigue resistance of concrete. This is particularly beneficial for structures like bridges and pavements, which are subjected to continuous traffic loads.
  4. Enhanced Durability in Harsh Environments: Structures exposed to aggressive environmental conditions, such as freeze-thaw cycles, chemical attack, and abrasion, benefit greatly from fiber reinforcement. Fibers provide an added layer of defense against these deteriorative forces, extending the service life of the concrete.

The Growing Concrete Fiber Market

The global concrete fiber market has been experiencing significant growth, driven by the rising demand for durable and high-performance construction materials. According to market research, the concrete fiber market is projected to grow at a robust rate in the coming years. Factors contributing to this growth include:

Conclusion

Concrete fibers represent a significant advancement in construction technology, offering a simple yet highly effective solution to improving the durability of concrete structures. As the concrete fiber market continues to expand, driven by the need for more resilient and sustainable building materials, the adoption of fiber-reinforced concrete is set to become a standard practice in the industry. Whether it's for controlling cracks, enhancing toughness, or ensuring long-term performance in harsh environments, concrete fibers are proving to be an indispensable component in modern construction.

2024.05.16 10:44 Sudden-Reward-9297 Would it be weird to get a tattoo inspired by my former teacher?

My former chemistry teacher was my all time favourite out of all the teachers ive ever had in my life and I honestly cherish those classes I had with him and our class.
On our last day he gave out cards to everyone where he drew a different chemical structure for each student, not really based on anything he just drew a random one for each student. I really miss that period of my life and chemistry will always be my favourite subject, partly because of my teacher.
Would it be weird if I got the chemical structure, my teacher drew, tattooed on me? I'm not really sure if I would be morally obligated to send him an email or if that's totally unnecessary.

Efficiency is paramount. On average, individuals allocate roughly 15 minutes weekly to shower cleaning. Materials like solid surface and acrylic can potentially halve this duration, courtesy of their smooth, non-porous attributes. In comparison, natural stone, due to its inherent porosity, demands more cleaning time, especially if not consistently sealed with a sealant. However, with diligent care and sealing, natural stone can offer enduring elegance and durability, lasting for a long time.

Durability

Optimizing the high durability of chosen materials is essential to ensure value for money. To illustrate, when adequately cared for, solid surface and porcelain tiles can endure for over 30 years. This lifespan surpasses many conventional materials by 50%, which may necessitate replacement or extensive upkeep within two decades.

2024.05.16 04:13 Bubzoluck The Story that is Gepirone - How Late to the Party Can You Be?

So originally this was a question from a redditor, u/Madmax0622, about why Gepirone hasn't been on the market yet despite being approved in September, 2023 and doing some research into has led to a rabbit hole of murder, intrigue, and one very disappointed boy having his father arrested at his 7th birthday party. Okay, not really, but the story is interesting and there is some important points to make about how drugs become approved and how data is represented. So i thought I would mkae it a full post (and comments have a smaller character limit).

What the hell is Gepirone?

Gepirone (Exxua) is a novel azapirone drug that is thought to work as a partial agonist at the Serotonin-1a (5HT-1a) receptor. This is a fancy way of saying that Geprione is a drug that is structurally similar to other serotonin receptor agonists. In the United States we only have Buspirone (Buspar, approved 1986) as our 5HT-1a agonist but internationally there are several others such as Perospirone (Lullan, Japan), Tandospirone (Sediel, Japan), and Binospirone (China). All in all, these drugs share very similar structures and only really differ in their pharmacokinetic properties such as half life, bioavailability, and first pass metabolism.
Where Gepirone differs from these other 5HT-1a agonists is that it is a partial agonist which means that when administered into the body, it creates a partial response to the receptor rather than a full response. While Gepirone is novel because it is the first drug who's primary mechanism of action (MOA) is this partial agonism at 5HT-1a, it is not an unknown one. Several common medications also have this mechanism, such as some newer antidepressants (Trazodone, Vilazodone, Nefazaodone), old and new antipsychotics (Haloperidol, Olanzapine, Clozapine, Ziprasidone), and some other known anti-anxiety chemicals (cannabidiol, LSD, and gingko biloba).
So if Gepirone wasn't the first drug to work on 5HT-1a, why did it get delayed?

What did the data say?

Well I should say first that Gepirone did show benefit. In a double blind trial of two different doses of Gepirone in treating depression, patients received either a high dose, low dose, or placebo and were found to have lower depression scores (HAM-D) at the end of 6 weeks. Based on these results (among other trials, it takes years and millions to submit a drug for approval--im paraphrasing here), Gepirone's pharma company Organanon submitted their data to the FDA. Their package of data contained one positive phase 3 trial--a randomized trial of over 200 participants with drepssion who either received Gepirone and had a reduction in depression score of 9.05 points (17% reduction in depression score) vs those who received placebo and had a 6.75 reduction in depression score (13% reduction) after 8 weeks of treatment.
Feeling dejected, Organanon was sitting on the marble steps outside the main FDA office when little Fabre-Kramer came walking by.
"Hey Organanon, did the FDA deny your reapplication?" Fabre-Kramer asked. "Yeah, they said my drug failed to show explicit benefit. That in the analysis of the main endpoints, submitting 25 studies and only have 2 be positive against placebo and the rest be negative or fail when challenge other established drugs doesn't show positive results." "Man that really sucks. How much did you spend on developing this drug?" "About $1.3 billion." "Well that's not too bad, you just got NuvaRing (2001, still makes up 22% of their revenue) approved and are making a killing off of it. Likewise you are still making boatloads off of Mirtazapine (1997)." "Well don't tell anyone but we are actually in a major scandal with Medicaid in Massachusetts and Texas where we were defrauding state government," Organanon lamented. "Yikes, that sucks," Fabre-Kramer said, "Hey, why don't I take Gepirone off yours hands. Afterall I originally got it from Bristol-Myers Squibb in 1993 before I sold it to you in 1998." "Aight, bet."
And so Gepirone was handed off to Fabre-Kramer in 2005 so Organanon could write off this whole venture to their shareholders.
Fabre-Kramer started by conducting an additional randomized trial of 238 adult participants who received Gepirone ER for 8 weeks. Results were....the same as before--people who received Gepirone showed a 10 point reduction while the placebo group showed an 8 point reduction. In 2007 this third trial was included and sent over to the FDA for approval (for the 3rd time) and the FDA looked at it and said, "yeah no thanks kid." They said that the positive results from the most recent phase 3 trials was good but the 23 other small trials that showed negative results was troubling.
Fabre-Kramer then pushed up their glasses and pulled up their suspenders a bit and said, "I'd like to appeal that decision" and in 2012 the decision was send to the FDA's Psychopharmacologic Drugs Advisory Committee (PDAC) in Dec 2015. In a 9-4 ruling, the committee voted that Fabre-Kramer smelled funny and they were dummy and that their drug was not good enough. They said they could resubmit another drug application again when they had more data.
Eventually Fabre-Kramer did submit another application in 2022 and Gepirone ER was approved by the FDA for the treatment of Depression in 2023.

If Gepirone was denied so many times, does that mean its a bad drug?

It would be easy to look at Gepirone's story and say that the drug is just not good enough and the pharma companies had to complete multiple trials (and thus generate more data) to prove its efficacy. Truthfully, its a mixed bag and I am going to try to shoot down the middle hear so you can make an informed decision on your own if you want to try Gepirone ER.
The Good
The Bad
Alright, this is where my brain is wanting to stop for now. If I think of additional things to add I will throw them in. Cheers!

2024.05.16 01:15 Linico_3694 Data structure for inventory app

Visual representation of potential data schemes
Hi all, I am a laboratory manager working on creating a Power App to track chemical inventory for the R&D group of a start-up company. Cash flow is an issue for us, so I'm limited to the tools available through Microsoft365 or free software.
I'm new to Power Apps and have played around enough to think it will probably do everything I need it to, and I can find answers to individual technical questions online. I'm struggling, though, to figure out the best way to organize and store my backend data. From what I can tell so far, SharePoint lists are better than Excel files for this purpose when using Power Apps as a frontend. My company does not pay for Dataverse or SQL licenses.
I will be the primary user of the app and curator of the underlying data, but it is likely other laboratory employees will also use it to find items and log them as they arrive or are consumed. The data I would like the user to be able to see and edit are:
Chemical name Chemical formula CAS# Container size Size units University barcode Company barcode Manufacturer UPC Number in stock Site Room Shelf/Location
These data can be generally organized into the chemical, product, and container categories:
Each chemical has a name, formula, and CAS#. These data go together and never change.
Each product contains a given chemical (with associated formula and CAS#) and has a manufacturer, UPC, size, and unit. These data go together and change slowly or not at all. Ideally I would like to be able to use a barcode reader to scan a product's UPC to retrieve its manufacturer, chemical contents, and size/unit data. A given manufacturer may produce different products that contain different amounts of the same chemical, and of course will produce many products containing different chemicals. We may have multiple containers of the same product on hand at any given time.
Each container represents a product and contains a chemical. Containers seem like the most logical basic unit of tracking for this system. Each container may or may not have either a university barcode (our R&D facilities are leased from a university and their EHS department applies individual barcodes to each chemical container that arrives on campus) or a company barcode (we have another facility away from the university and the capability to generate our own barcodes for individual chemical containers). Ideally I would like to use these barcodes to associate each individual chemical container with its location (site, room, and shelf).
The total number of chemical containers on hand now is around 300 and will likely grow to 450-600 in the coming year. Turnover is also around 300-500 containers per year.
My first pass at creating an inventory app involved loading all of these data into a single SharePoint list. I understand this to be a suboptimal data structure (the list contains redundant information and lots of null fields). But I don't have the experience to weigh how much of an issue this actually presents for my use case. In this most naive structure, I would simply add and remove records as containers arrived and were consumed. Inventory on hand would be tracked by tallying containers of the same product. This might actually fulfill most of our needs as far as knowing what we have on hand and what we need to order more of. It would not, however, give us any information on usage rates (not really information we need for now, but obviously useful in some contexts) or maintain a record of used containers. Again, that's not a function I'm sure we need, but I can imagine it being useful to answer to university EHS that a particular container was used and disposed of if their records and ours are inconsistent.
The second approach I've considered is a star schema in which chemicals (with associated formulae and CAS numbers), products (with associated UPCs, manufacturers, and sizes) and locations (sites, rooms, and shelves) are stored in dimension tables (SharePoint lists) and a fact table (another list with foreign keys referencing the ID fields in dimension tables) is used to log the receipt and disposal (and potentially location transfer) events of individual chemical containers. Inventory would be tracked either by summing receipt and disposal events or maintaining a count variable for each product. With turnover of say 500 containers per year this table would grow by a minimum of 1,000 records per year. This would put the fact table at 5,000 records in 3-5 years and then necessitate managing the view limit in SharePoint. I understand this is doable but don't really have a sense for the practical implications.
The third approach would be to use dimension tables for chemicals, products, and locations as above, but instead of using a fact table to log events, simply use an inventory table to store a record of each container received, with a status column that could be changed from 'in stock' to 'disposed of' at the appropriate time. This is another probably naive approach that would, as I see it, cut the number of records in the central table by at least half, since only one record is required per container instead of a 'received' record and a 'disposed of' record. But I don't know enough about data management theory/practice to know what problems this might create.
I would love to hear any guidance you may have about these data schema or any alternatives you might suggest. I would like this system to be as robust and flexible as possible within the limitations of my data storage options and abilities, but I also have a tendency to overthink things and not enough experience to tell when I've moved from "sensible and good enough" to "dramatically overengineered." So, with the context that this system will likely handle between 500 and 1200 records per year, involves 13-15 total columns/attributes, and is not (as of now) part of any larger BI or analytics initiative, should I put significant effort into organizing a solid foundational data scheme, or just use a single wide table to get a "good-enough" picture of inventory on hand?
Thanks in advance!

Hi,
I'm an automation engineer and have about 7 years of experience. I recently joined a small company in Europe. We make water treatment installations mainly for the chemical and food-processing industry. I've always worked for machine building companies.
When I joined I was very surprised to see that pretty much all of the PLC code is not written by the automation team, but by the process team in a word document. For example, but more detailed:
Bit-x = NOT alarm-device1 AND start-request1 Timer-x (TON) = val-device2 > setpoint7, time = setpoint8 And so on .. I am expected to type over this code in the syntax known by the PLC.
This was new to me, since in the previous companies I've worked for most of the time I was only given the order, which contained a brief description of the project, and a P&ID. There would often be a kick-off meeting by the project manager. If I had questions I would discuss with the project manager or client directly. This has always worked just fine for me.
I feel like my job now comes down to the following tasks: a lot of typing over code, IO-testing, setting up network, configuring hardware, commissioning on site (although always with a process engineer who basically tells me what to do / what to change).
At the moment my job feels really uninteresting to me this way. I also feel like I could do a much better job myself writting code / structuring data / designing a better standard. I do have an engineering degree, where I had plenty of coding while none of the processing team had coding during their education.
I am wondering if this is common practice. How does your job look like in automation? Is it more common to work out the code yourself? Do you get any description, P&ID, code to do so?
