RESUMO
BACKGROUND: The development of digital technologies and the evolution of open innovation approaches have enabled the creation of diverse virtual organizations and enterprises coordinating their activities primarily online. The open innovation platform titled "International Natural Product Sciences Taskforce" (INPST) was established in 2018, to bring together in collaborative environment individuals and organizations interested in natural product scientific research, and to empower their interactions by using digital communication tools. METHODS: In this work, we present a general overview of INPST activities and showcase the specific use of Twitter as a powerful networking tool that was used to host a one-week "2021 INPST Twitter Networking Event" (spanning from 31st May 2021 to 6th June 2021) based on the application of the Twitter hashtag #INPST. RESULTS AND CONCLUSION: The use of this hashtag during the networking event period was analyzed with Symplur Signals (https://www.symplur.com/), revealing a total of 6,036 tweets, shared by 686 users, which generated a total of 65,004,773 impressions (views of the respective tweets). This networking event's achieved high visibility and participation rate showcases a convincing example of how this social media platform can be used as a highly effective tool to host virtual Twitter-based international biomedical research events.

Vascular dementia (VaD) is well recognized as the second most familiar form of dementia in the aged population. The present study is aimed to investigate the neuroprotective effects of ethanolic extract of leaves of Ocimum sanctum (EEOS) against hyperhomocysteinemia (HHcy)-induced vascular dementia (VaD) in Wistar rats. HHcy was induced by administering L-methionine (1.7 g/kg, p.o) for 4 weeks. Donepezil (0.1 mg/kg, p.o.) and EEOS (100 mg/kg, 200 mg/kg, 400 mg/kg, p.o.) were administered from the 14th day of L-methionine treatment. The behavioral impairment caused due to HHcy in rats was assessed by the Morris water maze (MWM) and Y-maze tests using a video tracking system. Biochemical estimations and aortic ring assay were also performed followed by a molecular docking analysis of active chemical constituents present in the leaves of Ocimum sanctum Linn. In this study, the EEOS treatment in hyperhomocysteinemic rats has showed significant improvement in spatial learning and working memory performance. The EEOS treatment further increased nitric oxide bioavailability and significantly altered all serum and brain biochemical parameters in a dose-dependent manner. The docking analysis revealed that among all the phytoconstituents of Ocimum sanctum compound (IX), molludistin has showed good inhibitory activity against S-adenosyl homocysteine, thus preventing homocysteine formation and may be responsible for potential effects of EEOS against HHcy-induced VaD. From our results, we conclude that EEOS can be used as a promising adjunct therapy for treatment of HHcy-induced VaD and oxidative stress.
