Assam University is a collegiate central public university located at Silchar, Assam, India. It was founded in the year 1994 by the provisions of an act enacted by the Parliament of India. The Governor of Assam is the Chief Rector and the President of India is acting as the Visitor of the university. The Chancellor is the ceremonial head of the university while the executive powers rest with the Vice-chancellor. The university has sixteen schools which offer Humanities, Languages, Environmental Sciences, Information Sciences, Life Sciences, Physical Sciences, Social Sciences, Law, Technology and Management Studies. There are 42 departments under these sixteen schools. The five districts under the jurisdiction of Assam University have 73 undergraduate colleges as on 31 March 2020. Assam University is an institutional signatory to the Global Universities Network for Innovation (GUNI), Barcelona and United Nations Global Compact (UNGC) for its commitment to educational social responsibilities.Assam University is the second Central University of Assam after Tezpur University. Both were established in 1994.The main campus, in an area of 600 acres (2.4 km2), is located at Dorgakuna, near Irongmara about 20 km from Silchar, while a second campus, Diphu Campus, has an area of 90 acres, in Diphu, Karbi Anglong district of Assam.
The rapid digital transformation of tourism has created smart tourism ecosystems that use interconnected technologies, cloud services, AI, and online transactions. These innovations improve efficiency, personalisation, and visitor experiences, but they also increase the risk of organised cybercrime. Smart tourism ecosystems face major cyber threats, and this study examines how cybersecurity promotes responsible tourism. The study analyses scholarly literature and industry reports to identify ransomware attacks, phishing, identity theft, payment fraud, data breaches, and fake booking platforms using qualitative secondary data analysis. The study emphasises cybersecurity's role in responsible tourism by enhancing data protection, transparency, and accountability. Governance issues like fragmented responsibilities, small tourism enterprises' limited cybersecurity capacity, and regulatory compliance issues remain major obstacles. The study found that secure, resilient, and responsible smart tourism ecosystems require cybersecurity in tourism governance and business operations.
The high-precision observations from the Planck and BICEP/Keck have imposed stringent bounds on the tensor-to-scalar ratio, ruling out many standard inflationary models. The recent bound from Atacama and SPT along with DESI provides a different viable landscape, making it difficult for the inflationary models to sustain. Amid these increasingly stringent and conflicting observational constraints, modified gravity theories offer a compelling avenue to restore the viability of inflationary models. With this motivation, we study mutated hilltop inflation within f(ϕ,T) gravity, where a scalar field is non-minimally coupled to the trace of the energy–momentum tensor. The scalar spectral index ns, the tensor spectral index nt, and the tensor-to-scalar ratio r are calculated and their trajectories are presented in the ns−r plane. The results are then confronted with the latest CMB bounds from Planck, BICEP/Keck, ACT DR6, SPT, and DESI DR2. We report that MHI can predict r∼10−3 and is compatible with the latest CMB & DESI bound SPA+BK+DESI at 1σ CL.
Cancer remains a major global health challenge. Natural compounds, such as curcumin, resveratrol, genistein, thymoquinone, and paclitaxel, show chemopreventive activity by modulating signaling pathways, including PI3K/Akt, NF-κB, and p53. These agents also promote apoptosis, autophagy, and DNA repair. However, their clinical use is restricted by poor solubility, instability, and low bioavailability. Nanotechnology offers solutions by improving stability, enhancing pharmacokinetics, and enabling targeted delivery. Liposomes, polymeric nanoparticles, dendrimers, and albumin-bound systems amplify the anticancer effects of natural compounds. Preclinical studies confirm improved efficacy, while early clinical trials reveal both promise and barriers. The key translational challenges include immune clearance, large-scale reproducibility, and regulatory approval. This review highlights the synergy between nanotechnology and natural compounds in cancer chemoprevention and outlines opportunities for future research.
Medicinal plants from the Eastern Himalayas of Northeast India are integral to traditional therapies for inflammation. This study evaluated the anti-inflammatory potential of 23 reported phytochemicals isolated from this region by targeting TNF-α, a critical mediator of autoimmune disorders. TNF-α production was induced in human peripheral blood mononuclear cells using 100 ng/mL lipopolysaccharide for 24 h and quantified using ELISA. The IC50 was calculated by probit regression, with methotrexate as the reference standard (IC50 = 1.96 µM; 94
In this research work, we have successfully designed and developed a Schiff base fluorescent chemosensor for detecting Zn2+ and Cu2+ ions using absorption and fluorescence spectroscopy. A stable complex formation of L with Zn2+ was observed with a noticeable isosbestic point in the absorption spectra. Moreover, fluorescence “on-off” response with Zn2+ and Cu2+ was observed which indicates selectively senses of Zn2+ and Cu2+. This sensor displays 1:1 stoichiometric ratio with metal ions by 1H NMR titration, mass spectra, BH-plot and Job’s plot. Moreover, the recyclability of L was assessed through EDTA showing an efficient fluorescence “off-on-off” signal response. Furthermore, the (L+Zn2+) ensemble formed was used for selective recognize F− ion. L achieved an INHIBIT logic function using different chemical inputs and corresponding emission as output. The optimized structures of L and complexes (L+Zn2+ and L+Cu2+) were used to understand spectral properties using DFT which further calculated different reactivity descriptors. This selective sensitivity of L towards Zn2+ were successfully studied and used for detection of Zn2+ intracellularly in mouse breast adenocarcinoma cell.
