The Potential of QP3VH-Chitosan Peptide as Biomimetic Remineralization in Early Dental Caries Treatment: An In Vitro Study.

Objectives:  The development of remineralization biomimetics using organic peptide molecules is expected to resemble the hydroxyapatite (HA) mineralization process in tooth enamel. The development of an amelogenin derivative peptide combined with antimicrobial peptide was designed, resulting in QP3VH. This combination then was mixed with chitosan as a carrier.

A novel synthetic peptide analog enhanced antibacterial activity of the frog-derived skin peptide wuchuanin-A1.

In recent years, there has been a growing focus on the development of novel antibacterial compounds for clinical applications, such as antimicrobial peptide (AMP). Among the developed AMP, wuchuanin-A1, a coil-shaped bioactive peptide derived from frog skin, has been reported to exhibit antibacterial, antifungal, and antioxidant activity, but there are limited studies on its potential as an antibacterial agent. Therefore, this study aims to molecularly modify the sequence of wuchuanin-A1 to enhance its antibacterial properties.

Proteome of monocled cobra ( venom and potent anti breast cancer peptide from trypsin hydrolyzate of the venom protein.

Anticancer peptide is one of the target in the development of new anticancer drug. Bioactive peptide can be originated from isolated free peptide or produced by hydrolysis of protein. Protein is the main component of venom, and due to the toxicity of the venom, it can be assessed as the source of anticancer peptides.

Academic Performance in Medical Education During the COVID-19 Pandemic: A Scoping Review.

Backgrounds: Several academic performance studies during the COVID-19 pandemic on education outside medicine showed varying results. This scoping review aims to identify research trends in medical education that focus on the academic performance of medical students during the COVID-19 pandemic to enable available research to be mapped and summarized, and gaps in research results can be identified.

Methods: The authors applied the Arksey and O'Malley framework to conduct the scoping review.

Comparative proteomics of Cannabis sativa plant tissues.

Comparative proteomics of leaves, flowers, and glands of Cannabis sativa have been used to identify specific tissue-expressed proteins. These tissues have significantly different levels of cannabinoids. Cannabinoids accumulate primarily in the glands but can also be found in flowers and leaves.

Cloning and over-expression of a cDNA encoding a polyketide synthase from Cannabis sativa.

A polyketide synthase has been suggested to play an important role in cannabinoid biosynthesis in Cannabis sativa L. This enzyme catalyzes the biosynthesis of olivetolic acid, one of the precursors for cannabinoid biosynthesis. Using a reverse transcriptase-polymerase chain reaction (RT-PCR) based on the DNA homology of chalcone synthase (EC 2.

Methods for the analysis of cannabinoids in biological materials: a review.

Various methods for the analysis of cannabinoids in biological materials, including plant and human body materials, are reviewed. Chromatographic methods, such as TLC, GC and HPLC, and non-chromatographic methods, mainly immunoassays, are discussed and compared. Chromatography is most commonly used in the analysis of plant material, with GC apparently offering the most advantages.
