Use Cases from Literature
Here are a few of the many examples of how scientists use the Wiley Registry across various applications from the literature.
| Article Title | DOI Link | Summary | Application Area |
| Circulating levels of butyrate are inversely related to portal hypertension, endotoxemia, and systemic inflammation in patients with cirrhosis | https://doi.org/10.1096/fj.201901327R | Short-chain fatty acids (SCFAs) are gut-derived products present in the blood stream. In this work, it is shown using GC-MS on blood samples that patients with cirrhosis have decreased levels of SCFAs, and these decreased levels are associated with more advanced liver disease. The SCFAs were identified using both the retention times for standard compounds, and with standard spectra from the National Institute of Standards and Technology (NIST) 08 Mass Spectral Library and the Wiley Registry of Mass Spectral Data, 7th Ed. | Pharmaceutical |
| Emission of novel volatile biomarkers for wheat powdery mildew | https://doi.org/10.1016/j.scitotenv.2021.146767 | Biogenic volatile organic compounds (BVOCs) are emitted from both plant vegetation and their pathogens. Thus, BVOCs can act as biomarkers for detection or early forecasting of infections. BVOCs are hereby identified to serve as biomarkers for the onset of powdery mildew, one of the world’s leading diseases for wheat. VOC identification was based on background subtracted mass spectra identified using the NIST (National Institute of Standards and Technology)/EPA/NIH Mass Spectral Library 17 (2017) and the Wiley Registry of Mass Spectral Data, 10th edition (2014). | Agriculture |
| Effect of lactic acid fermentation of red beetroot juice on volatile compounds profile and content | https://doi.org/10.1007/s00217-023-04304-y | Spontaneous fermentation in food products is impacted by naturally occurring lactic acid bacteria (LAB). LAB can be used to increase a food product’s microbiological safety, nutritional properties, and health benefits. Because VOCs are formed during the fermentation process, this study analyzed VOCs’ profiles and content of red beetroot juice fermented with different LABs. The VOCs were identified by comparing retention times, retention indices, and mass spectra with the Wiley Registry 7th Edition Mass Spectral Library and the National Institute Standards and Technology (NIST) 2005 Mass Spectral Library. | Food Science |

To combat this, researchers propose using natural plant extracts such as Indian Hawthorn (HAL), which have demonstrated significant antifungal activity against fungal pathogens. The Wiley Registry 8th Edition was used to identify the components in HAL, found to be various organic compounds that may exhibit potential pharmacological and antimicrobial activities. Thus, HAL extract could serve as a natural and sustainable solution to manage fungal infestations in plants. | Environmental |
| Prediction of clinically significant prostate cancer through urine metabolomic signatures: A large-scale validated study | https://doi.org/10.1186/s12967-023-04424-9 | Prostate cancer affects over 1 million men a year and there are currently no accurate markers for predicting potentially lethal prostate cancer before biopsy. This study aimed to develop urine tests to predict clinically significant prostate cancer in men at risk. The Wiley Registry 11th Edition and other databases were used to identify metabolites in urine samples for further marker panel selection. Using this information, three models were developed for predicting benign vs. cancerous cases and insignificant vs. significant prostate cancer. These models were found to predict significant prostate cancer based on the National Comprehensive Cancer Network guidelines with very high accuracy, thereby informing the necessity of biopsy in men with an elevated risk of prostate cancer. | Metabolomics |
| Potential Ameliorative Effect of Propolis Against the Developmental Toxicity Induced by Oxaliplatin in Albino Rats Prior and During Pregnancy | https://dx.doi.org/10.21608/ejz.2023.231135.1103 | Chemotherapeutic drugs such as oxaliplatin are often used in cancer therapy to treat different tumors, but use of these either prior to or during pregnancy can lead to health issues in the mother and their offspring. Propolis, a resinous product collected by bees from plants, is known to have a protective effect against medication toxicity. The Wiley Registry 9th Edition and other databases were used to identify the components of the propolis extract. It was found that coadministration of propolis with oxaliplatin can significantly reduce the histopathological alterations in renal and spleen tissues caused by oxaliplatin, potentially owing to the antioxidant influence of propolis. | Pharmaceutical |
| Repellent effects of Chinese cinnamon oil on nymphal ticks of Haemaphysalis longicornis, Rhipicephalus haemaphysaloides, and Hyalomma asiaticum | https://doi.org/10.1007/s10493-023-00855-7 | Ticks can cause diseases in non-human vertebrates and are ranked second to mosquitoes as a vector of human pathogens. DEET is the gold standard repellent but can be a potential risk to human health. The repellent activity of Chinese cinnamon oil against nymphal ticks was studied. The oil’s components were identified using the Wiley Registry 7th Edition. Tests were conducted at varying oil concentrations and observations were made at increasing time intervals. Chinese cinnamon oil was found to have a strong repellent activity against ticks, comparable to that of DEET, offering a safer repellent alternative. | Agriculture |

This study investigated the chemical composition of the essential oils extracted from two species of Cinnamomum, namely C. tamala and C. camphora and studied their acetylcholinesterase inhibitory activity. The Wiley Registry of Mass Spectral Database 8th Edition and other databases were used to identify components of the extracts, found to be various compounds with phenylpropanoids and oxygenated monoterpenes as the major classes. The compounds were evaluated as acetylcholinesterase inhibitors and showed that Cinnamomum oils are potential candidates for further clinical studies. | Pharmaceutical |
| Simultaneous choice bioassays accompanied by physiological changes identify civetone and decanoic acid as pheromone candidates for giant pandas | https://doi.org/10.1002/zoo.21532 | Chemicals present in urine of the solitary giant panda (Ailuropoda melanoleuca) are thought to play an important role in mate identification. During breeding season, females will deposit chemical signals to advertise receptivity to potential mates. The goal of this study was to determine if specific volatile compounds found in female urine could be considered as pheromones that elicit behavioral and physiological responses in males. The Wiley Registry 10th Edition/NIST 2012 Mass Spectral Library and other databases were used to identify components of the urine. Experimental simultaneous choice trials were conducted with captive male giant pandas. Androgen levels were significantly elevated (p < .05) in one male after exposure to 1H-pyrrole-2-carboxaldehyde, decanoic acid, and civetone. These data suggested that civetone and decanoic acid in female urine may motivate sexual responses in males. | Zoology |
