Rhesus rotavirus (RRV) infection primes biliary epithelial cells to respond hyperactively to low-dose lipopolysaccharide (LPS), triggering upregulation of matrix metalloproteinase-7 (MMP7) via TLR4/NF-κB signaling. Loss of endotoxin tolerance in biliary atresia (BA), associated with reduced expression of IRAK-M, leads to uncontrolled inflammation and tissue damage. MMP7 acts as a dual-function molecule, contributing to both extracellular matrix remodeling and amplification of inflammatory signaling in BA.

In this paper we define, for the first time, the modified fractional derivative with Mittage-Leffler kernel of Riemann-Liouville (R-L) type of arbitrary order [Formula: see text]delta. We derive the infinite series representations for the modified derivatives of R-L and Caputo types and present a relationship between them. We also investigate the modified derivatives for the Dirac delta functions, and study related fractional differential equations.

In this study, we apply the Natural Transform Iterative Method (NTIM), a relatively new and efficient analytical tool for solving fractional differential equations (FDEs). NTIM combines the Natural Transform and Daftardar-Jafari polynomials to construct approximate solutions without the need for discretization, small parameters, or linearization. This method is particularly effective for handling fractional partial differential equations due to its simplicity and rapid convergence.

A six-membered benzene ring is fused with a five-membered imidazole ring at positions four and five, generating benzimidazole, the benzo derivative of imidazole and a bicyclic aromatic chemical compound. Benzimidazole is a significant pharmacophore in a variety of physiologically active heterocyclic compounds due to its distinctive characteristics and structural framework. Because benzimidazole is both aromatic and heterocyclic, it interacts with a range of biological targets metal ion interactions, π-π stacking, and hydrogen bonding.

Angiotensin-converting enzyme 2 (ACE2) has been reported to be the primary host cell receptor for recognizing SARS-CoV and SARS-CoV-2 spike proteins. This host-cell element, despite having a crucial role in normal cells, may be hijacked by viruses to invade human cells. It has been reported that ACE2 trafficking to the cell membrane is mediated by other cellular factors, such as the endoplasmic reticulum resident chaperone, named glucose-regulated protein 78 (GRP78).
