Drug Delivery Approaches | Chapter 01 | Modern Advances in Pharmaceutical Research Vol. 2

This review discusses the different biological barriers that affect the delivery of therapeutic agents through membranes, such as intestinal mucosa, Brain Blood Barrier (BBB), and mediators of transport such as efflux transporters and the approaches for overcoming such barriers. The approaches illustrated in this review include: utilizing natural occurring transporters to deliver drugs specifically to their targets, nucleoside analogues delivery, CYP-activated prodrugs that target drugs to the liver, modification of passive diffusion by efflux pumps, intestinal transporters such as PEPT1 and GLUT1, Carrier Mediated Transport (CMT) systems for transporting nutrients, vitamins or hormones into the central nervous system, tissue selective drug delivery, administration of an exogenous enzyme to reach the tumor site which is followed by systemic administration of non-toxic prodrugs (ADEPT, GDEPT and VDEPT), enzymes involve in the bioconversion of ester-based prodrugs for activation (hydrolysis) of prodrugs to their active forms, brain targeted Chemical Delivery Systems (CDS), amino acid prodrugs to improve oral bioavailability, sustained drug delivery and intravenous drug delivery. Furthermore, Receptor-Mediated Transcytosis (RMT) for efficacious delivery of Nano particles via the intestinal mucosa and BBB, and the prodrug chemical approach based on intra molecularity to deliver anti-cancer drugs is discussed.

Consensus Summit: Lipids and Cardiovascular Health in the Nigerian Population | Chapter 09 | Current Trends in Food Science Vol. 1

Aims: To issue a consensus statement on Lipids and Cardiovascular Health and the impact of their interrelationship in Nigerian Population. Study Design: Experts from a range of relevant disciplines, deliberated on different aspects of Lipids and Cardiovascular Health in the Nigerian Population at a Summit. Place and Duration of Study: The Summit was held in April 2016 at the Nigerian Institute of Medical Research. Methodology: Presentations were made on central themes after which expert participants split into four different groups to consider the questions relevant to different sub themes of the title. Consensus was arrived at, from presentations of groups at plenary. Conclusion: With the increase in the prevalence of NCDs, especially Cardiovascular Disease in Nigeria, and the documented evidence of deleterious effects of lipids, the expert panel called for an urgent need to advocate for the general public and health professionals to make heart-friendly

A Review on Gongronema latifolium, an Extremely Useful Plant with Great Prospects | Chapter 11 | Recent Advances in Biological Research Vol. 3

Gongronema latifolium is a plant that has a wide range of nutritional and ethnomedical uses in different tropical African communities. Scientific reports on the chemical composition and bioactivity (anti-inflammatory, antimicrobial, antidiabetic, antioxidant, anticancer and allelopathic properties) of the plant material by different authors are discussed in this review. Future prospects of the plant extracts in the areas of herbal formulations, food preservation, alcoholic fermentation and beer production, drug discovery and allelopathy are also highlighted.

An Overview of Ultrasonic Technology and Its Applications in Food Processing, Preservation and Quality Control | Chapter 03 | Current Research in Science and Technology Vol. 3

Ultrasound is one of the emerging technologies that were developed to minimize processing, maximize quality and ensure the safety of food products. In recent years, ultrasound technology has been used as an alternative processing option to conventional thermal approaches. Although Ultrasonication methods have been used for years in research and diagnostics, major advances have been made in the last decade. The applications for which high power ultrasound can be used range from existing processes that are enhanced by the retrofitting of high power ultrasonic technology, to the development of processes up to now not possible with conventional energy sources. The present paper reviews the generation, principle mechanism, properties, process parameters, applications, merits and demerits and future trends of the ultrasound technology in the food processing.
