Floating In-Situ Gel for Gastric Retention Delivery
Abstract: When taken orally, medications with a limited window of absorption in the gastrointestinal tract (GIT) are typically accessible to the extremities due to the partial release of the active component and the brief residence period at the absorption site. Because they prolong the duration of the drug's presence in the stomach, they are made with high density and have the capacity to swell. Because oral fluids go more quickly through …

The Ames Test in Twenty-first Century
Abstract: Since the 19th century, industrial development has increased exposure to mutagens and possible carcinogens. In order to avoid these health risks, several techniques have been developed to recognize genotoxins. In the 1970s, Dr. Bruce Ames and colleagues, studying the histidine operon of Salmonella typhimurium, observed that histidine (−) auxotroph mutants were reverted to histidine (+) upon exposure to a mutagen. The researchers further observed that known carcinogens were mutagenic to …

In Silico Analysis and Molecular Docking Studies of COX-2 Inhibitors for Anti-Inflammatory Activity
Abstract: Although nonsteroidal anti-inflammatory drugs (NSAIDs) are frequently used to treat pain, lower fevers, and control inflammation, they frequently cause gastrointestinal side effects because they inhibit the COX-1 and COX-2 enzymes. Despite their effectiveness and lack of gastrointestinal side effects, selective COX-2 inhibitors have been linked to cardiovascular risks. To find new COX-2 inhibitors that are safer and more effective, this study uses in silico techniques, such as molecular docking and …
