Global Dental Publications in PubMed Databases between 2009 and 2019-A Bibliometric Analysis

The objective of this study was to evaluate the publications in the field of dentistry on the PubMed database over a span of 10 years, from 2009 to 2019. Articles published between January 2009 to December 2019 were searched for in the MEDLINE database via PubMed. Data analysis was done using R-base packages, including the specialized R-packages Bibliometrix and String. For descriptive statistics and sequence charting, SPSS version 23.0 was used. A total of 104,975 articles were extracted, with a total of 153,530 authors in the given time frame. The proportion of articles steadily increased from 2009, plateauing at its peak from 2010 to 2016, and then seeing a decline from 2017 to 2019. Journal articles (60.58%), comparative studies (16.05%) and case reports (10.8%) were recorded as the most reported type of publication globally, accounting for 81.43% of the total documents extracted. All the articles came from 81 countries, with the USA reporting the greatest number of published articles (45,911). Dentistry proves to be a multi-faceted arena and many researchers and authors around the globe are contributing to the burgeoning literature over time.

GC-MS analysis of phytoconstituents from Amomum nilgiricum and molecular docking interactions of bioactive serverogenin acetate with target proteins

Amomum nilgiricum is one of the plant species reported from Western Ghats of India, belonging to the family Zingiberaceae, with ethno-botanical values, and is well-known for their ethno medicinal applications. In the present investigation, ethyl acetate and methanol extracts of A. nilgiricum were analyzed by Fourier transform infrared spectrometer (FTIR) and gas chromatography-mass spectrometry (GC-MS) to identify the important functional groups and phytochemical constituents. The FTIR spectra revealed the occurrence of functional characteristic peaks of aromatic amines, carboxylic acids, ketones, phenols and alkyl halides group from leaf and rhizome extracts. The GC-MS analysis of ethyl acetate and methanol extracts from leaves, and methanol extract from rhizomes of A. nilgiricum detected the presence of 25 phytochemical compounds. Further, the leaf and rhizome extracts of A. nilgiricum showed remarkable antibacterial and antifungal activities at 100 mg/mL. The results of DPPH and ferric reducing antioxidant power assay recorded maximum antioxidant activity in A. nilgiricum methanolic leaf extract. While, ethyl acetate leaf extract exhibited maximum α-amylase inhibition activity, followed by methanolic leaf extract exhibiting aldose reductase inhibition. Subsequently, these 25 identified compounds were analyzed for their bioactivity through in silico molecular docking studies. Results revealed that among the phytochemical compounds identified, serverogenin acetate might have maximum antibacterial, antifungal, antiviral, antioxidant and antidiabetic properties followed by 2,4-dimethyl-1,3-dioxane and (1,3-13C2)propanedioic acid. To our best knowledge, this is the first description on the phytochemical constituents of the leaves and rhizomes of A. nilgiricum, which show pharmacological significance, as there has been no literature available yet on GC-MS and phytochemical studies of this plant species. The in silico molecular docking of serverogenin acetate was also performed to confirm its broad spectrum activities based on the binding interactions with the antibacterial, antifungal, antiviral, antioxidant and antidiabetic target proteins. The results of the present study will create a way for the invention of herbal medicines for several ailments by using A. nilgiricum plants, which may lead to the development of novel drugs.

Dental sciences related articles data published in a Basic Medical Sciences Journal from Iran

This data aimed to audit the dental sciences related articles published in Iranian Journal of Basic Medical Sciences (IJBMS) from 2007 to 2015 over a 9 year period performed using web-based search. The data were analyzed for topic of dental sciences, type of article, international collaborations, source of funding, number of authors and authorship trends. Out of the total 18 data related to dental sciences, original articles (12), review articles (4) and short communications (2) contribute the major share. Regarding the relationship with dental sciences, the maximum number of data were related to oral pathology and microbiology (16) followed by oral medicine and radiology (7) and periodontics (7). Among the data related to dental sciences, oral cancer (3) and gingival and periodontal diseases (3) followed by dental plaque and caries (2) and orthodontic tooth movement (2) form the major attraction of the contributors. The largest numbers of data related to dental sciences were received from Mashhad University of Medical Sciences, Mashhad (4) and Tehran University of Medical Sciences,Tehran (2).The present data were compared with previous bibliometric studies done related to dental sciences (Shamim et al., 2017a, 2017b).
