... is a field of mathematics which combines two different branches of study, specifically algebra and linear algebra. Algebra and linear algebra can be defined as (1):. Algebra: A field of mathematics which analyzes polynomial equations using letters and symbols to represent unknown values. Linear Algebra: The investigation of a system of linear equations using several variables. Thus, algebraic geometry uses several variables for systems of polynomial equations. Algebraic geometry does not necessarily aim to solve these equations, but rather formulate statements about the geometric structure for the set of solutions belonging to these polynomial equations (algebraic varieties). When studying algebraic geometry, polynomial equations can be of various degrees (denoted as d). Polynomial equations of several variables are investigated to discover what their geometric structure might be. Algebraic geometry is a rather abstract field of mathematics. It is a field which involves a lot ...

Lipid-based formulations (LBFs) is a formulation strategy for enabling oral delivery of poorly water-soluble drugs. However, current use of this strategy is limited to a few percent of the marketed products. Reasons for that are linked to the complexity of LBFs, chemical instability of pre-dissolved drug and a limited understanding of the influence of LBF intestinal digestion on drug absorption. The aim of this study was to explore intestinal drug solubilization from a long-chain LBF, and evaluate whether coadministration of LBF is as efficient as a lipidbased drug formulation containing the pre-dissolved model drug carvedilol. Thus, solubility studies of this weak base were performed in simulated intestinal fluid (SIF) and aspirated dog intestinal fluid (DIF). DIF was collected from duodenal stomas after dosing of water and two levels (1 g and 2 g) of LBF. Similarly, the in vitro SIF solubility studies were conducted prior to, and after addition of, undigested or digested LBF. The DIF fluid was ...
In vitro dissolution testing is a critical component of drug product development programs and is often used as a surrogate for in vivo performance. Consequently, mechanistic modelling of in vitro dissolution studies and informed data interpretation early in the formulation development process is crucial.

Three hundred and fifty subjects from approximately 80 sites across seven countries will be enrolled in the study. Subjects will be treated with IFN beta-1a (Rebif® New Formulation) in real life settings according to the clinical and paraclinical course and laboratory findings as routinely evaluated by the physician. Data related to AEs; subjects adherence to treatment, reasons for treatment discontinuation; number and reasons of missed injections; and the clinical and paraclinical data on efficacy regarding relapses will be captured.

In addition to size, particles of low density (typically , 0.1 g/cm3) are desirable for high-efficiency delivery to the lungs. It is a strategy borrowed from nature in the dispersal of spores and pollen.. Most dry powder inhalant products on the market are lactose blends of coated crystalline small molecules.. "If you design the right powder-one that fluidizes and disperses at low energy-you can make a simpler device," he said. "If a device is simpler for patients to use, they are more adherent to their medication.". For these reasons, Miller believes that engineered particles are the future of the industry.. "One way I look at characterization of engineered particles is its another solid dosage form," he said. "Those of you who work on tablets, our lives are quite similar.". When it comes to topical formulations, product characteristics include pH, particle size, polymorphism, rheological studies, globule size, and dissolved/undissolved drug.. The quality attribute of highest interest is the ...
Assessment: 3-hour examination (85%), best 3 out of 4 assessed worksheets (15%).. Prerequisites: MA106 Linear Algebra, MA249 Algebra II: Groups and Rings. Leads To: Content: Galois theory is the study of solutions of polynomial equations. You know how to solve the quadratic equation $ ax^2+bx+c=0 $ by completing the square, or by that formula involving plus or minus the square root of the discriminant $ b^2-4ac $ . The cubic and quartic equations were solved ``by radicals in Renaissance Italy. In contrast, Ruffini, Abel and Galois discovered around 1800 that there is no such solution of the general quintic. Although the problem originates in explicit manipulations of polynomials, the modern treatment is in terms of field extensions and groups of ``symmetries of fields. For example, a general quintic polynomial over $Q$ has five roots $ \alpha_1.\dots.\alpha_5 $ , and the corresponding symmetry group is the permutation group $ S_5 $ on these.. Aims: The course will discuss the problem of ...

It can be computed in a completely analytical way. Take:. $$ F_n = F_{n-1} + F_{n-2} + F_{n-1}F_{n-2} $$. Adding $1$ to both sides and factorizing we obtain:. $$ F_n + 1 = (F_{n-1} +1)(F_{n-2}+1) $$. Now let $G_n = F_n + 1$ :. $$ G_n = G_{n-1} G_{n-2}$$. Taking the logarithm in some base $b$ :. $$ \log_b{G_n} = \log_b G_{n-1} + \log_b G_{n-2}$$. Which we rewrite, letting $H_n = \log_b{G_n}$ , as:. $$ H_n = H_{n-1} + H_{n-2} $$ This suggests an effective way to compute $F_n$ . First of all we compute $H_0 = \log_b(1 + F_0)$ and similarly $H_1$. Then we determine $H_n$ in closed form. Since $H$ is a second-order recurrence with constant coefficients, $H_n$ is in the form:. $$ H_n = A\phi^n + B\psi^n $$. where $\phi, \psi$ are the solutions to the associated polynomial equation $h^2 = h +1$, namely $\frac{1 \pm \sqrt{5}}{2}$. Knowing $H_0$, $H_1$, we can determine $A, B$ as the solutions to the following system:. $$ \left \{ \begin{array}{r c l} H_1 & = & A\left( \frac{1 - \sqrt{5}}{2} \right) + ...

This article summarizes the principles of drug dissolution testing with an emphasis on the underlying scientific assumptions that are often not clearly described, or understood. It should be noted that the technique itself is extremely simple to use, however, current practices of selecting experimental conditions and the interpretation of dissolution results are seriously misunderstood, and require attention. To address these deficiencies, analysts should seek essential training in the areas of relevant physiology and pharmacokinetics. In the absence of such required training and knowledge of the subjects, it is highly unlikely that an analytical laboratory can generate relevant and accurate dissolution data, thus will fail in meeting the products development and evaluation objectives. Links to some articles on the subjects are provided which may help the analysts in improving their overall skills in these areas. Please click here for complete article. ...
