Abstract:
Colon-specific drug delivery systems (CDDS) can be used to treat a variety of colon-related issues, including ulcerative colitis, colon cancer, Crohn's disease, irritable bowel syndrome, and chronic pancreatitis. Many medications used to treat conditions other than colon problems may also be absorbed systemically through the colon. If drugs like proteins and peptides—which are known to disintegrate in the excessive gastric pH—are transported to the colon intact, colonic mucosa can ingest them and absorb them systemically. The intended delivery mechanism must particularly target the

Abstract:
Colon cancer (CC) is one of major causes of mortality and affects the socio-economic status world-wide. Therefore, developing a novel and efficient delivery system is needed for CC management. Thus, in the present study, lipid polymer hybrid nanoparticles of apigenin (LPHyNPs) was prepared and characterized on various parameters such as particle size (234.80 ± 12.28 nm), PDI (0.11 ± 0.04), zeta potential (−5.15 ± 0.70 mV), EE (55.18 ± 3.61%), etc. Additionally, the DSC, XRD, and FT-IR analysis determined drug entrapment and affinity with the selected excipient, demonstrating a promising drug a

Abstract:
Preterm infants have immature organ functions that predispose them to gut and immune disorders. Developmental delays at preterm birth may affect various organs differently at term-corrected age. We hypothesized that gut and immune maturation in moderately preterm neonates depends more on birth and postnatal factors than on advancing postconceptional age (PCA). Using preterm pigs as models, we investigated how gut and immune parameters develop until term-corrected age and how these differ from those in term counterparts. Preterm ( n = 43, 106 days of gestation) and term pigs ( n = 41, 116 days

Abstract:
Polysaccharide biomaterials have gained significant importance in the manufacture of nanoparticles used in colon-targeted drug delivery systems. These systems are a form of non-invasive oral therapy used in the treatment of various diseases. To achieve successful colonic delivery, the chemical, enzymatic and mucoadhesive barriers within the gastrointestinal (GI) tract must be analyzed. This will allow for the nanomaterials to cross these barriers and reach the colon.

Abstract:
Regardless of so many advancements in the treatment, colon cancer still stands third in cancer-related deaths worldwide. Toxicity associated with conventional drugs is one of the major problems associated with chemotherapy. Targeted delivery works by concentrating the medication in the tissues of interest and reducing the concentration in remaining tissues. This delivery system helps the drug molecule to reach preferably to the desired site. The targeting will lower the requirement of a higher dose of the drug thus reducing the dosage frequency.
