Time-release” drugs work by releasing a drug to the body at a constant rate such that the drug concentration at one time is not large enough as to cause harmful side effects OR not low enough to the point where it is an ineffective therapeutic. A design schematic of a time-release pill is shown below. Explain how it works from an osmotic pressure standpoint.

A flat (not spherical) tissue engineered skin (thickness 2.5 mm) is attached to the bottom of a dish and cultured with cell media atop it (which has an oxygen concentration of 0.15 mol/m3). The diffusivity of oxygen in the skin is 3.4 E-9 m2/s, and according to experiments that you’ve performed, you want to make sure that the concentration of oxygen in the device doesn’t fall below 0.06 mol/m3. (Below that concentration harms the cells.) The rate of oxygen consumption is -5.9 E-17 mol/[cell◦s]. What is the maximum cellularity (in cells/mL, three significant digits) that this tissue engineered skin can support?
The active drug substance given above contains a carboxylic acid group. Ionizable proton of carboxylic acid (circled in red taken), the pKa value is given as 3.5. This drug must be absorbed through the plasma membrane to pass. The speed of passage through the plasma membrane depends on the polarity of the molecule. Charged and polar molecules are slower than the membrane, neutral and hydrophobic molecules pass more rapidly. Your stomach Its pH is about 1.5 and the pH of the small intestine is about 6.0. whether this drug passes through the stomach or small intestine more into the blood. you wait Explain. In order to get full points, the ionic molecule in the stomach and intestines Compare them in terms of charge and polarity, indicating their state.
Read this article and answer the following question There are 3 different Metformin ER products available: Glucophage XR Glumetza ER Fortamet ER All 3 formulations are available generically but they are not interchangeable as they all use different release mechanisms. Glucophage XR uses a dual hydrophilic polymer system. The drug is slowly released by diffusing through a gel matrix, also known as GelShield diffusion system. Once the tablet is swallowed, the outer layer of the tablet forms a gel layer and the metformin contained within is slowly released. Due to this release mechanism, Glucophage XR can not be cut or split. Glumetza ER uses a mechanism known as gastro-retentive technology (also known as 'Modified Release'). The tablets are designed to remain in the stomach and deliver metformin to the upper GI tract over an extended period of time. Like Glucophage XR, Glumetza ER can not be cut or split. Fortamet ER uses single-composition osmotic technology (SCOT). After…

Which of the following options shows the correct order of fastest to slowest motion of chloride ions, glycine and proteins through the separating gel? Chloride ions > Proteins > Glycine Glycine > Chloride ions > Proteins Chloride ions > Glycine > Protein Protein > Chloride ions > Glycine You are trying to separate a mixture of AMP, ADP, and ATP using ion exchange chromatography. Select appropriate supplies for your experiment. A positively charged column, deprotonated buffer, NaCl of same concentration. A positively charged column, protonated buffer, NaCl of increasing concentration. A negatively charged column, protonated buffer, NaCl of increasing concentration You cannot separate nucleotides using ion exchange chromatography.
Question 2 Which of the following is/are true with regard to the therapeutic index and the therapeutic window of a drug (there may be more than one true statement)? Therapeutic index is defined as ED50/TD50. Drugs with a narrow therapeutic window are best suited for minor conditions like headache or muscle pain. Therapeutic window is the dose range that maximizes efficacy at minimum toxicity. Drugs with a wide therapeutic window can be used to treat serious life-threatening diseases. All of the above are correct.
Amoeboid cells that migrate through our tissues, such as the class of white blood cells known as neutrophils, often do so in a directed manner, triggered, for instance, by chemical signals released by pathogens such as bacteria. Directed migration in response to a chemical stimulus is known as chemotaxis. Part of an efficient chemotactic response is the ability of cells to polarize. As is the case with our structurally-polar polymers like F-actin or microtubules, polarization here refers to an asymmetry in the cells, rather than an electrical charge. In this case, it involves one part of the cell becoming the “front” (or leading edge) and another the rear. In a well-polarized, migrating cell, it’s been observed that an active form of Rac (which, in turn, can activate ARP 2/3) is concentrated towards the front of the cell, whereas an active form of Rho (which, in turn, can activate formin, inhibit cofilin/ADP, and activate myosin II) is found toward the rear of the cell. Based on your…
