Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

open access: yesFood Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation).

Postmortem interval determination using 18S-rRNA and microRNA

Science and Justice - Journal of the Forensic Science Society, 2014
The importance of determining postmortem interval (PMI) is crucial to criminal, civil and forensic cases. The precise estimation of PMI is a critical step in many death investigations. A technique exploiting the level of RNA, 18S rRNA and microRNA to estimate PMI was investigated.

Performance of 18S rRNA in Littorinid Phylogeny (Gastropoda: Caenogastropoda)

Journal of Molecular Evolution, 1998
In the past, 18S rRNA sequences have proved to be very useful for tracing ancient divergences but were rarely used for resolving more recent ones. Moreover, it was suggested that the molecule does not contain useful information to resolve divergences which took place during less than 40 Myr.

N6-methyladenosine modification in 18S rRNA promotes tumorigenesis and chemoresistance via HSF4b/HSP90B1/mutant p53 axis

open access: yesCell Chemical Biology, 2023
Aberrant N6-methyladenosine (m6A) modification on mRNA is correlated with cancer progression. However, the role of m6A on ribosomal RNA (rRNA) in cancer remains poorly understood.

Comprehensive single-PCR 16S and 18S rRNA community analysis validated with mock communities, and estimation of sequencing bias against 18S.

Environmental Microbiology, 2021
Universal primers for SSU rRNA genes allow profiling of natural communities by simultaneously amplifying templates from Bacteria, Archaea, and Eukaryota in a single PCR reaction.

18S rRNA V9 metabarcoding for diet characterization: a critical evaluation with two sympatric zooplanktivorous fish species

open access: yesEcology and Evolution, 2016
The potential of the 18S rRNA V9 metabarcoding approach for diet assessment was explored using MiSeq paired‐end (PE; 2 × 150 bp) technology. To critically evaluate the method′s performance with degraded/digested DNA, the diets of two zooplanktivorous ...

Reverse Transcription of 18S rRNA with Poly(dT)18 and Other Homopolymers

Plant Molecular Biology Reporter, 2012
Ribosomal 18S RNA is widely used as a housekeeping gene in expression studies, including end-point PCR, Northern analysis, and real-time experiments. However, there are two disadvantages and two points of error introduction in using 18S rRNA as a reference gene. First, 18S has no poly(A) tail, so it is commonly reverse transcribed with specific primers

18S rRNA sequences and phylogeny of platyhelminthes

Biochemical Systematics and Ecology, 1993
Abstract The phyletic relationships, and hence the systematic position, of freshwater planarians (Tricladida, Turbellaria, Platyhelminthes) within the Turbellaria, and of Platyhelminthes within the Metazoa are uncertain. This stems partially from the shortcomings of the characters and techniques clasically used in the systematic study of these groups.
