Adverse Effects of Xenogenic Scaffolding in the Context of A
Lamas et al. Trials (2019) 20:387 https://doi.org/10.1186/s13063-019-3504-3 RESEARCH Open Access Adverse effects of xenogenic scaffolding in the context of a randomized double-blind placebo-controlled study for repairing full- thickness rotator cuff tears José Ramón Lamas1†, Carlos García-Fernández2, Pilar Tornero-Esteban1, Yaiza Lópiz2, Luis Rodriguez-Rodriguez1, Luis Ortega3, Benjamín Fernández-Gutiérrez1*† and Fernando Marco2† Abstract Purpose: The purpose of the study was to compare the safety and efficacy of autologous mesenchymal stem cells (MSCs) embedded in a xenogenic scaffold for repairing the supraspinatus tendon. Methods: This was a randomized, double-blind and placebo-controlled trial evaluating patients with full-thickness rotator cuff tears (Eudra-CT, 2007–007630-19). Effectiveness was evaluated using the Constant score and a visual analogue pain scale (VAS). Constant score has four domains including pain (15 possible points), activities of daily living (20 possible points), mobility (40 possible points), and strength (25 possible points). Scores range from 0 points (most disability) to 100 points (least disability). The structural integrity of the repaired tendon was assessed by magnetic resonance imaging (MRI) according to Patte and Thomazeau classification criteria. The primary study end point was an improvement in the Constant score by 20 points at one year compared to initial assessment. Results: The trial was stopped due to adverse effects observed in both groups. Only thirteen patients were included and analyzed. The Constant questionnaire showed a significant improvement in the MSC treatment group compared with the preoperative data (p = 0.0073). Secondary outcome measures were similar in both groups. -
Grade 6 Science Mechanical Mixtures Suspensions
Grade 6 Science Week of November 16 – November 20 Heterogeneous Mixtures Mechanical Mixtures Mechanical mixtures have two or more particle types that are not mixed evenly and can be seen as different kinds of matter in the mixture. Obvious examples of mechanical mixtures are chocolate chip cookies, granola and pepperoni pizza. Less obvious examples might be beach sand (various minerals, shells, bacteria, plankton, seaweed and much more) or concrete (sand gravel, cement, water). Mechanical mixtures are all around you all the time. Can you identify any more right now? Suspensions Suspensions are mixtures that have solid or liquid particles scattered around in a liquid or gas. Common examples of suspensions are raw milk, salad dressing, fresh squeezed orange juice and muddy water. If left undisturbed the solids or liquids that are in the suspension may settle out and form layers. You may have seen this layering in salad dressing that you need to shake up before using them. After a rain fall the more dense particles in a mud puddle may settle to the bottom. Milk that is fresh from the cow will naturally separate with the cream rising to the top. Homogenization breaks up the fat molecules of the cream into particles small enough to stay suspended and this stable mixture is now a colloid. We will look at colloids next. Solution, Suspension, and Colloid: https://youtu.be/XEAiLm2zuvc Colloids Colloids: https://youtu.be/MPortFIqgbo Colloids are two phase mixtures. Having two phases means colloids have particles of a solid, liquid or gas dispersed in a continuous phase of another solid, liquid, or gas. -
1 090304 Quiz 8 Introduction to Polymers (Chemistry) This Week We
090304 Quiz 8 Introduction to Polymers (Chemistry) This week we ran a suspension polymerization to make polystyrene, a solution polymerization to make polyacrylamide and we discussed Ziegler-Natta polymerization to make polypropylene. 1) Suspension polymerization is similar to emulsion polymerization. a) Describe the importance of water to emulsion and suspension polymerization. Does water play an identical role in these two polymerizations? Is water a solvent? b) Describe the initiator that we used in suspension polymerization. What condition is needed to initiate this reaction? Why was a different initiator used in the emulsion polymerization? c) What is divinyl benzene and why is it included in this reaction? d) What controls the size of the polymer beads (droplet size) that result from suspension polymerization? e) What was the advantage of emulsion polymerization (over suspension polymerization) that lead to its development by Goodyear Tire and Rubber in the 1920’s? 2) Polyacrylamide is soluble in water as is the monomer acrylamide therefore this is a solution polymerization. a) Use the words ferric and ferrous to describe the initiator system for this polymerization. Why is this called a redox system? b) When hydrogen peroxide was added to the reaction mixture it turned from a faint bluish green to red (rust color). Later the color seemed to fade. Why did it change color? c) What temperature was needed to perform this polymerization? Why? d) How was polymer separated from the viscous reaction mixture after polymerization? e) Explain the disadvantage of solution polymerization compared to emulsion or suspension polymerization. 3) We looked at Ziegler-Natta polymerization briefly. -

However this route of drug administration fails at bypassing the first pass metabolism of the drug in liver with poor bio availability. Oral route of drug administration also fails in uncooperative /unconscious semiconscious / pediatric subjects. Transdermal patch, a new drug delivery system through skin to the parenteral circulation has been the most recently discussed topic in pharmacology and medicine as it is a noninvasive route of drug administration, delivered in a sustained / pre fixed dosage with no / extremely less first pass metabolism and better bio availability. Most importantly it can be used in semiconscious / unconscious & pediatric subjects without affecting their hemodynamics. The transdermal patches have many beneficial factors however they also come with some major drawbacks like varieties of formulation, design and quality of adhesiveness. This articles provides an insight of transdermal patch in terms of its mechanism of action, advantages, disadvantages and future scope of it in the medical science. -

Chapter 18 Solutions and Their Behavior
Chapter 18 Solutions and Their Behavior 18.1 Properties of Solutions Lesson Objectives The student will: • define a solution. • describe the composition of solutions. • define the terms solute and solvent. • identify the solute and solvent in a solution. • describe the different types of solutions and give examples of each type. • define colloids and suspensions. • explain the differences among solutions, colloids, and suspensions. • list some common examples of colloids. Vocabulary • colloid • solute • solution • solvent • suspension • Tyndall effect Introduction In this chapter, we begin our study of solution chemistry. We all might think that we know what a solution is, listing a drink like tea or soda as an example of a solution. What you might not have realized, however, is that the air or alloys such as brass are all classified as solutions. Why are these classified as solutions? Why wouldn’t milk be classified as a true solution? To answer these questions, we have to learn some specific properties of solutions. Let’s begin with the definition of a solution and look at some of the different types of solutions. www.ck12.org 394 E-Book Page 402 Homogeneous Mixtures A solution is a homogeneous mixture of substances (the prefix “homo-” means “same”), meaning that the properties are the same throughout the solution. Take, for example, the vinegar that is used in cooking. Vinegar is approximately 5% acetic acid in water. This means that every teaspoon of vinegar contains 5% acetic acid and 95% water. When a solution is said to have uniform properties, the definition is referring to properties at the particle level. -

Biphasic Dosage Forms Suspensions and Emulsions Unit 7
BIPHASIC DOSAGE FORMS SUSPENSIONS AND EMULSIONS UNIT 7 Dr.N Damodharan Professor and Head Department of Pharmaceutics SRM College of Pharmacy Suspensions Heterogenous biphasic dosage form -- solid is dispersed in liquid medium. Dispersed phase, dispersion medium PROPERTIES: --Rapid settling ---Easily redisperdible,pourable ---if parenteral—flow through syringe needle ---if external---spread easily ---Pleasing in colour , odour, appearance. Types: ---Deflocculated ---Flocculated PROPERTIES: ---Interfacial property ---Electrical property zDispersions containing coarse particles, usually 10 to 50 um in size, are referred to as coarse dispersion. zDispersions containing particles of smaller size are termed fine dispersions (0.5 to 10 um) Suspensions In general sense, Suspension may include: ¾ Gels ¾ Lotions ¾ Magmas and Milk ¾ Mixtures Reasons for Suspensions ¾ Certain drugs are chemically unstable when in solution but stable when suspended. ¾ Suspension insures chemical stability while permitting liquid therapy. ¾ Many patients prefer liquid form than solid forms for swallowing. ¾ Convenience in administration ¾ Safety and convenience of liquid doses for infants and children. ¾ Disagreeable taste of certain drugs when given in solution is negligible when the drug is administered as undissolved particles of a suspension, e.g chloramphenicol Features Desired in a Pharmaceutical Suspensions 1. A properly prepared suspension should settle slowly and should be readily re- dispersed upon gentle shaking of the container. 2. The characteristics of the suspension should be such that the particles size of the suspensoid remains fairly constant throughout long periods of undisturbed standing. 3. The suspension should pour readily and evenly from its container Physical Features of the Dispersed Phase of a Suspension Good pharmaceutical suspensions, the particle diameter is between 1 to 50.
