3D-Bioprinting: A stepping stone towards enhanced medical approaches

In the past few decades, tissue engineering has been seen unprecedented escalation driving the field of artificial tissue and organ construct and brought metamorphosis in regenerative medicine. Prime advancement has been attained through the expansion of novel biomanufacturing approaches to devise and convene cells in three dimensions to fabricate tissue contrive. Accompaniment manufacturing differently known as 3D bioprinting is leading prime innovation in a number of applications in life sciences such as tissue and organ construct, personalized drug dosing, cancer model and heart tissue engineering. Overall, this review summarizes most prevalent bioprinting technologies; including laser-based bioprinting, extrusion bioprinting, injection bioprinting, stereolithography as well as biomaterial such as bioink. It also explores 3D industries, approaches such as Biomimicry, autonomous self-assembly, mini tissues and biomedical applications. Existing challenges that impede clinical mileage of bioprinting are also discussed along with future prospective.Keywords: Bioprinting, tissue engineering, tissue and organ construct, medicinal approac

Delivery of Analeptics via Painless Transdermal Patches

Putting into service a preliminary transdermal patch on the skin, an appropriate dosage of drug can be delivered to the site of therapeutic effect within the body. This supreme delivery system is painless and more efficacious. These patches are designed by adhering analeptic compounds over them. In conjugation to these therapeutic compounds essential oils having anti-inflammatory, anticancer, antioxidant and healing properties are also used, increasing the durability of drug. Natural and synthetic polymers comprising cellulose derivatives and polyvinyl chloride respectively are significant in their designing. There are assorted categories of transdermal drugs, depending on the layers of therapeutic compounds, inclusive of single layer, bi-layer, multilayer, matrix and reservoir. Transdermal delivery has its own wondrous aptness. It enhances bioavailability of drugs eliminating the first pass effect in gastrointestinal tract. It is efficient in treating not only extraneous skin infection, but it also holds a strong curable impact on internal disorders extending from hormonal imbalance to either neurodegenerative diseases or cardiovascular diseases. Nicotine patches are prodigiously practiced treating nicotine addicts.
