Biodegradable microcapsules containing bupivacaine/dexamethasone produce an anesthetic duration of 7-11 days in animal models. In this investigation, we explored the effect of increasing doses (Part 1) and the effect of including dexamethasone (Part 2) on the onset, density, and duration of analgesia and anesthesia produced by bupivacaine microcapsules. Concentrations ranging from 0.3125% to 5....

Designing and fabricating multifunctional nanocomposite microcapsules are considerable interests in both academic and industrial research aspects. This work first reports an innovative approach to in situ synthesize and assemble fluorescent carbon dots (CDs) into polyelectrolyte microcapsules, obtaining highly biocompatible nanocomposite microcapsules with excellent luminescence that facilitate...

The present study examined the physical, chemical, microbial, and sensory characteristics of Queso Blanco cheese supplemented with powdered microcapsules containing tomato extracts (0.5-2.0%) during storage at 7°C for 60 d. The lactic acid bacterial count and lycopene concentrations in Queso Blanco cheese supplemented with powdered microcapsules were significantly higher than those of the contr...

The present study describes the development of multilayer microcapsules by 11 alternate additions of chitosan (Chi) and sodium dodecyl sulfate (SDS) in a combined emulsification and phase coacervation method based on ionic interactions. After an alkali treatment, microcapsules are applied on polyester (PET) fabric by a padding process to investigate their wash-durability on fabric. Air atmosphe...

L-Lysine was microencapsulated by the spray-dry met.hod for improvement of the balance of alllino acids in ruminants. The rumen-bypm;s lllicrocCljJsulc was jJrqmn~d using zein or shellac as an outer coat.ing agcnt [or protection against microbial degradation in the rumen. L-Lysine was generated with a .yield of ,')0% in casp of zein microcapsules and :3:3% in shellac microcapsules and a mean pa...

Important advances in the transplantation of islets of Langerhans have recently been achieved using alginate-based microcapsules (De Vos 2006). These microcapsules safely protect the transplanted cells from graft rejection in the absence of long-term immunosuppression. Recent progress has allowed us to effectively eliminate the development of fibrosis surrounding the implanted microcapsules (De...

Many herbs and spices have been recommended traditionally as galactagogues and several commercial formulations prepared using herbs. Due to the presence of various compounds such as polyphenols, flavonoids, isoflavones and terpenes, bitter and stringent taste is elicited that make the consumption of these herbal preparations unpleasant. Moreover, these compounds are unstable when exposed to env...

Microencapsulation of model drug, acetylsalicylic acid into bio-based polymer, alginatepectin matrix and chitosan had been undertaken in this work to characterize the microcapsules based on their composition. Alginate-pectin with the proportion of 40:60 solution was prepared with 0.3 g of drug. This mix was homogenized and atomized using nitrogen gas into 1.0M calcium chloride solution to form ...

The density of microcapsules was compared on 'Golden Delicious' mature and immature foliage, fruit, and 1-yr-old limbs after dip treatments with Phase III oriental fruit moth, Grapholita molesta (Busck), microencapsulated pheromone. Microcapsules were counted with a dissecting microscope at 50x magnification after apple tissues were treated with a two-step dye staining process to increase the v...

Natural plant extracts have been shown as effective and attractive dental biomaterials with promising properties for restorative/reparative procedures. These bioactive extracts, however, may lose their stability when exposed to air, moisture, or light, if not well-protected. Here, we present a novel technique for sequestering bioactive extracts within polymer microcapsules for long-term stabili...
