Rafie JohanAbstractUsing Starch as a capping agent, zinc oxide (ZnO) nanoparticles (NPs) have been synthesized by the low cost and simple chemical precipitation technique. The confirmation of the hexagonal crystal structure of ZnO NPs were demonstrated by X-ray powder diffraction (XRD) pattern. The Fourier-transform infrared spectroscopy (FTIR) spectroscopy confirms Zn-O stretching vibrations. The scanning electron microscopy (SEM) and Transmission electron...

Herein, an enzyme-free surface-enhanced Raman scattering (SERS) platform was proposed for sensitive and reliable detection of target miRNA-21 using a corrective internal standard (IS)-based ratiometric SERS probe coupled with mismatched catalytic hairpin assembly (CHA) amplification....

Therefore, we have developed a novel electrochemical sensor to determine IMQ, for the first time. A glassy carbon electrode (GCE) was modified by a new composite comprising of ionic liquid-based molecularly imprinted polymer (MIP) and gold nanoparticles/graphene oxide (Au/GO). The MIP/Au/GO nanocomposite was synthesized through non-covalent imprinting ...

Publication date: Available online 23 August 2019Source: MethodsAuthor(s): Jianji Chen, Cari Sagum, Mark T BedfordAbstractSignal transduction is driven by protein interactions that are controlled by posttranslational modifications (PTM). Usually, protein domains are responsible for “reading” the PTM signal deposited on the interacting partners. Protein domain microarrays have been developed as a high throughput platform to facilitate the rapid identification of protein-protein interactions, and this approach has become broadly used in biomedical research. In this review, we will summarize the history, developme...

This study was done by collecting wild PU and cultivated PU and compared with a counterfeit which is commonly found in the market. Fourier Transform Infrared (FTIR) and Two-Dimension Infrared (2DIR) for the qualitative analysis are often regarded as green methods because the original resources of the test sample are preserved. The different spectral patterns of the counterfeit PU compared with the genuine PU were clearly indicated in 1D FTIR spectrum. The 2DIR spectrum of counterfeit PU showed more than 70% dissimilarity compared to genuine PU. This rapid and simple sample preparation enhances the speed of qualitative anal...

CONCLUSION ; Optimal management of esophageal corrosive injuries remains a debatable issue in terms of choosing between conservative therapy and surgical intervention. For this reason, the need for long-term follow up regardless the ingested substance and the preferred therapeutic approach is highlighted.

In conclusion, SCC of rectum is a distinct entity and it is important to shed some light on this rare condition because it has different epidemiology, etiology, pathogenies and requires a different treatment approach than other colorectal carcinomas. Surgery is the primary treatment which consists of local excision versus radical resection and the need for adjuvant therapy. Abstract ID: 38 Figure 1
