Bioactive phenolic compounds in their natural form show beneficial effects on the gastrointestinal system. The kinetics of their release are important for understanding those effects. The aim was to study the kinetics of the release of phenolic compounds from apples during in vitro simulated gastrointestinal digestion by using modified equations of first- and second-order kinetics. 35% and 67% of total phenolic compounds were released in the gastric phase, and 26% and 27% in the intestinal phase (peel and flesh, respectively).

Drugs are most frequently administered by oral route. Although a few drugs taken orally are intended to be dissolved in the mouth, nearly all drugs taken orally are swallowed. A few drugs such as antacids are swallowed for their local action in the gastrointestinal tracts.

Abstract:
Cartilage damage is difficult to self-heal due to an avascular microenvironment and distinct mechanical properties. These features are a challenge in designing a cartilaginous tissue with repairing effect without producing any local infections. Thus, a biodegradable scaffold in which the drug can be incorporated is preferable. Drug delivery systems based on collagen sponges have progressively become remarkable biomaterials for different medical applications. The aim of this work was to design and characterize some collagen/chondroitin sulfate supports with doxycycline for cartilage tissue rege

Abstract:
The high degree of heterogeneity of the nervous and endocrine systems makes it extremely important for real-time monitoring of dynamic chemical changes at the single-cell level to gain a better understanding of the interaction of cells with their environment. Secretion mediated by exocytosis is one of the fundamental phenomena whose mechanism mimics the release of neurotransmitters at synaptic sites. Although the regulation of the secretory pathway has been studied extensively, its molecular mechanism is still not clear. It is important to develop methods that can follow real-time secretory pr

Abstract:
Andrographolide (AGP), a major component of Andrographis paniculata (Burm.f.) Nees (AP), has several biological activities. Nevertheless, poorly water solubility and low bioavailability of AGP lead to decrease clinical benefits. Therefore, this study aims to develop of AP extract-chitosan solid dispersion using central composite design (CCD) to enhance AGP release. AP crude extract was obtained by Soxhlet extractor using 85%v/v ethanol as a solvent extraction. Then, AP extract, chitosan, and poloxamer 188 in the concentrations provided by CCD was spray dried. The in-vitro release of AP extract

Abstract:
Cardiovascular Diseases, the common name for various Heart Diseases, are responsible for nearly 17.3 million deaths annually and remain the leading global cause of death in the world. It is estimated that this number will grow to more than 23.6 million by 2030, with almost 80% of all cases taking place in low and middle income countries. Surgical treatment of these diseases involves the use of blood-wetted devices, whose relatively recent development has given rise to numerous possibilities for design improvements. However, blood can be damaged when flowing through these devices due to the lac

Abstract:
Part I: The purpose of the investigation was to develop the extraction process that was simple, practical and giving high yield. The maceration of dried powder of Garcinia mangostana fruit husk with ethyl acetate gave yellow crystalline powder of mangostin. The yield was calculated as 7.47%. The identification of the Garcinia mangostanahusk extract was carried out by thin-layer chromatography (TLC) and differential scanning calorimetry. The TLC of mangostin was done by using the alumina sheet and ethyl acetate: hexane (3:1) as mobile phase. The Rf value as compared with standard mangostin was
