Biodegradable nano-polymers as delivery vehicles for therapeutic small non-coding ribonucleic acids.
Nowadays, small non-coding Ribo Nucleic Acids (sncRNAs) such as siRNA, miRNA and shRNA are extremely serving to gene regulation. They are involved in many biological processes and in an increasing number of studies regarding a variety of application of sncRNAs toward human health and relieving diseases ranging from metabolic disorders to those involving various organ systems as well as different types of cancer. One of the most severe limitations for applying RNA interference technology is the absence of safe and effective carriers for in vivo delivery, including localizing the molecules to a specific site of interest and sustaining the presentation of the payloads for a controlled period o…
Nano-delivery system targeting to cancer stem cell cluster of differentiation biomarkers
Cancer stem cells (CSCs) are one of the most important origins of cancer progression and metastasis. CSCs have unique self-renewal properties and diverse cell membrane receptors that induced the resistance to the conventional chemotherapeutic agents. Therefore, the therapeutic removal of CSCs could result in the cancer cure with lack of recurrence and metastasis. In this regard, targeting CSCs in accordance to their specific biomarkers is a talented attitude in cancer therapy. Various CSCs surface biomarkers have been described, which some of them exhibited similarities on different cancer cell types, while the others are cancer specific and have just been reported on one or a few types of …
Nano-materials for use in sensing of salmonella infections: Recent advances
Salmonella infectious diseases spreading every day through food have become a life-threatening problem for millions of people and growing menace to society. Health expert's estimate that the yearly cost of all the food borne diseases is approximately $5-6 billion. Traditional methodologies for salmonella analysis provide high reliability and very low limits of detection. Among them immunoassays and Nucleic acid-based assays provide results within 24h, but they are expensive, tedious and time consuming. So, there is an urgent need for development of rapid, robust and cost-effective alternative technologies for real-time monitoring of salmonella. Several biosensors have been designed and comm…
