The clustered regularly interspaced short palindromic repeat (CRISPR)/Cas system is best known for its role in genomic editing. It has also demonstrated great potential in nucleic acid biosensing. However, the specificity limitation in CRISPR/Cas has created a hurdle for its advancement.

The Situation, Background, Assessment, Recommendation (SBAR) communication technique is an evidence-based method shown to improve patient safety, and is embedded in some curricula of pharmacy and other health care professions. The aim of this study is to determine whether students can utilize the SBAR communication technique during an interprofessional skills assessment one year following initial instruction.
View Article and Find Full Text PDFAptamers have gained an increasing role as the molecular recognition element (MRE) in diagnostic assay development, since their first conception thirty years ago. The process to screen for nucleic acid-based binding elements (aptamers) was first described in 1990 by the Gold Laboratory. In the last three decades, many aptamers have been identified for a wide array of targets.

The present study was undertaken to investigate the role of PI3K/Akt/survivin pathway in alpha-santalol-induced apoptosis employing cultured LNCaP and PC-3 human prostate cancer cells. Treatment of prostate cancer cells with alpha-santalol (20, 40 μM) resulted in the down regulation of survivin and p-AKT (s-473) expression and statistically significant reduction in total survivin levels as evidenced by survivin ELISA assay.
View Article and Find Full Text PDFAtrazine is a common herbicide that is widely used to control weed growth in both agricultural and residential settings. It has been shown to act as an endocrine disruptor that affects aquatic organisms. Rapid and low-cost monitoring methods for atrazine is the first step to mitigate its widespread persistency.

The short half-lives of unmodified aptamers in vivo remain one of the major challenges in therapeutic aptamers. Much of the incremental successful therapeutic aptamer stories were due to modifications in the aptamer bases.
View Article and Find Full Text PDFAtrazine is an herbicide that is widely used in crop production at about 70 million pounds per year in the United States. Its widespread use has led to contamination of groundwater and other aquatic systems. It has resulted in many serious environmental and human health issues.

They can bind to user-defined targets with high affinity and specificity. There has been an increasing interest in the identification and application of nucleic acid molecular recognition elements, commonly known as aptamers, since they were first described in 1990 by the Gold and Szostak laboratories.
