Dataset Summary
The XML Open Access includes more than 3.4 million journal articles and preprints that are made available under license terms that allow reuse. Not all articles in PMC are available for text mining and other reuse, many have copyright protection, however articles in the PMC Open Access Subset are made available under Creative Commons or similar licenses that generally allow more liberal redistribution and reuse than a traditional copyrighted work. The PMC Open Access Subset is one part of the PMC Article Datasets
This version takes XML version as source, benefiting from the structured text to split the articles in parts, naming the introduction, methods, results, discussion and conclusion, and refers with keywords in the text to external or internal resources (articles, figures, tables, formulas, boxed-text, quotes, code, footnotes, chemicals, graphics, medias).
The dataset was initially created with relation-extraction tasks in mind, between the references in text and the content of the references (e.g. for PMID, by joining the refered article abstract from the pubmed dataset), but aims in a larger extent to provide a corpus of pre-annotated text for other tasks (e.g. figure caption to graphic, glossary definition detection, summarization).

"<title>Discussion</title>",
"<p>The\nliver, the major metabolic organ of our body, may have toxicity\ndue to various drugs like alcohol, anabolic steroids, nonsteroidal\nanti-inflammatory drug, and so on<italic>.</italic><sup> ##REF## </sup> Oxidative stress can be attributed to the major reason\nbehind this toxicity. Oxidative stress occurs due to the imbalance\nbetween free radicals generated and antioxidants present in the body.<sup> ##REF## </sup> Many medicinal plants display significant implications\ntoward traditional medicine for the treatment of hepatic diseases\nincluding hepatic disorders. Further these plants are being evaluated\nfor <italic>in vivo</italic> pharmacological activities to identify\npotent candidates. The generation of free radicals as products of\nmany biomolecular reactions plays major roles in the emergence of\ncancer and other health disturbances. It is also known that CCl<sub>4</sub> can induce the levels of various enzymes like ALT, AST, ALP,\nand \u03b3-GT in animal models. CCl<sub>4</sub> is also known to\ncause acute hepatocyte injuries that further result in the leakage\nof various hepatocyte enzymes. Many hepatoprotective agents from different\nnatural sources are reported to possess the ability to protect against\nsuch injuries by restoring the levels of the above enzymes along with\nretaining the levels of triglycerides, cholesterol, low-density lipoprotein, and high-density lipoprotein in\nthe serum to normalcy. Earlier reports have also shown the potential\nof polyphenolic compounds to play key roles in establishing such protective\nactivity.<sup> ##REF## </sup> Several mechanisms were reported\nwith animal models for the above observed activity with hepatoprotective\nagents that have strong ability to trap various metal ions like zinc,\ncalcium, and iron.<sup> ##REF## </sup> Herein, we have investigated\nthe hepatoprotective effects of <italic>C. paniculatum</italic> plant bioactive compounds against CCl<sub>4</sub>-induced hepatotoxicity\nin rats.</p>",
"<p>Internal antioxidant deficiency can be overcome by\nsupplementing\nwith external sources. Since polyphenolics are known to have high\nantioxidant potentials, their natural sources from plants have gained\nimmense significance for them to be explored for extracting and isolating\nthese polyphenolic antioxidant constituents.<sup> ##UREF## </sup> Among these antioxidants, flavonoids have a high health promoting\nrole through their antioxidant mechanism. Due to their high free-radical\nscavenging property, the flavonoids display significant roles toward\nmanaging various diseases and disorders. Among the flavonoids, quercetin,\nrutin, apigenin, catechin, and so on are also reported for their anti-hepatotoxic\nproperties.<sup> ##UREF## </sup> Enzymatic and non-enzymatic\ncomponents of the oxidative stress can be resolved through the plant\ncell defense system. A non-enzymatic system controls the cellular\nresponses against the free radicals, whereas enzymatic responses directly\nscavenge the free radicals and hence control the antioxidant defense\nsystem.<sup> ##REF## </sup> The qualitative chemical evaluation\nresults obtained from our studies support the presence of various\nclasses of chemical compounds like carbohydrates, proteins, flavonoids,\ntannins, phenolics, and steroids. The alcoholic extract of CPF exhibited\nhigh phenolics and flavonoids that influence the apparent antioxidant\nactivity compared to other extracts. Herein, the antioxidant activity\nis evaluated by various methods including DPPH, nitric oxide radical\nscavenging, ABTS, and reducing power assay. The IC<sub>50</sub> value\nfor the alcoholic extract was represented as 62.28 \u00b1 0.51, 2362.71\n\u00b1 9.39 51, and 193.09 \u00b1 5.84 \u03bcg/mL, respectively,\nfor DPPH, ABTS, and nitric oxide radical scavenging methods. The alcoholic\nextracts were further subjected to hepatoprotective activity evaluation\nusing CCl<sub>4</sub>-induced hepatotoxic models. The evaluation was\ncarried out by determining SGOT, SGPT, ALP, direct bilirubin, total\nbilirubin, and total protein content and also through histopathology\nof liver. The results obtained revealed a marked decrease in liver\nenzyme levels along with an increase in the total protein content\nwhen compared to toxic control groups that were similar to standard\ngroups administered with silymarin. The total bilirubin in the serum\nserves as a hepatic functional marker which is associated with hepatic\ndisorder along with acute disruption of hepatocellular architecture\nand function. Moreover, the toxicant-induced liver injuries also result\nin increased levels of bilirubin. The above findings are further supported\nby the results of histopathology analysis. In the toxic control group,\nthe liver histopathological characters were showing disarranged hepatic\ncellular architecture with cell necrosis, fatty degeneration, and\ncentral vein crowding. This was almost reframed to the normal liver\narchitecture by 200 mg/kg and 400 mg/kg body weight alcoholic extract\ntreatment. In order to identify the unique constituents of the extract,\nthe fractions displaying significant activities were separated by\ncolumn chromatography using a universal solvent system (hexane, ethyl\nacetate, and methanol), and the fractions were tested for the presence\nof phenolics and flavonoid contents by both qualitative and quantitative\ntechniques. Fractions 5 and 9 which showed better phenolic and flavonoid\ncontents were then considered for <italic>in vitro</italic> hepatoprotective\nanalyses using goat liver slice culture, and the activity was compared\nwith the alcoholic extract of the plant. Of the two fractions, fraction\n9 showed better activity. GC\u2013MS analyses followed by NIST library\nsearch revealed that the constituents responsible for the above activity\nmay be glyceric acid, gallic acid, pilocarpine, or pangamic acid,\nas shown in ##FIG## .

### Data Splits

## Dataset Creation
### Curation Rationale
Internal references (figures, tables, ...) were found using specific tags. Deciding on those tags was done by testing and by looking in the documentation
for the different kind of possible usage.
Then, to split the article into introduction, methods, results, discussion and conclusion, specific keywords in titles were used. Because there are no rules
in this xml to tag those sections, finding the keyword seemed like the most reliable approach to do so. A drawback is that many section do not have those
keywords in the titles but could be assimilated to those. However, the huge diversity in the titles makes it harder to label such sections. This could be the
work of further versions of this dataset.

### Social Impact of Dataset

### Discussion of Biases
The articles XML are similar accross collections. This means that if a certain collection handles the structure in unusual ways, the whole collection might not be as
well annotated than others. This concerns all the sections (intro, methods, ...), the external references (pmids) and the internal references (tables, figures, ...).
To illustrate that, references are sometime given as a range (e.g. 10-15). In that case, only reference 10 and 15 are linked. This could potentially be handled in a
future version.
