Self-healing composite hydrogels are prepared from sustainable biopolymers by a green chemistry approach and analyzed physicochemical mechanical characterization techniques for future injectable anticancer biomaterials. Water-soluble chitosan (WSC) was grafting polyethylene glycol (PEG), glutamic acid gallic onto the chain carbodiimide chemistry. This WSC showed fast gelation (t ? < 60 seconds)...

This article aims to describe a clinical case of the use injectable restorative technique with composite resin in patient an esthetic complaint anterior teeth. Producing direct restorations teeth when performed demands long time. Results often depend on operator's ability reproduce proper form, function, and esthetics. Lately, versatility resins has increased. As this material evolved, new tech...

Hydrogels have been used for biomedical applications in recent decades. They are a perfect candidate for regenerative medicine as they resemble the extracellular matrix of native tissues. In addition, their highly hydrated structure makes them a suitable choice for drug and other therapeutics delivery. Injectable hydrogels have increasingly gained attention due to their capability for homogeneo...

atropine (at) and oximes, alone or in combination, have been proven greatly valuable therapeutics in the treatment of organophosphates intoxications. an injectable mixture of at and obidoxime (ob) was formulated for administration by automatic self-injector. the aqueous single dose solution contained 275 mg obidoxime chloride and 2.5 mg atropine sulfate per 1 ml (220 mg and 2 mg per 0.8 effecti...

objective: to compare side effects between users of two kinds of injectable contraceptives (depo-medroxy progesterone acetate and cyclofem). materials and methods: this cross-sectional descriptive study included 250 women, aged 18-40 years, using depo-medroxy progesterone acetate (dmpa) or cyclofem. the volunteers were examined six months after using contraceptive, and they were asked about fol...

Engineering drug delivery systems (DDS) aim to release bioactive cargo a specific site within the human body safely and efficiently. Hydrogels have been used as matrices in different studies due their biocompatibility, biodegradability, versatility biomedical purposes. Microparticles also for similar reasons. The combination of microparticles hydrogels composite system has topic many research w...
