A stroke patient with persistently intermittent fever treated with gabapentin: A clinical case.

Fever is one of the most common complications in stroke patients and can generally be classified as either infectious or non-infectious. Infectious fevers are commonly caused by pulmonary infections, urinary tract infections, and secondary infections associated with medical interventions such as endotracheal intubation, urinary catheterization, and nasogastric tubes. Non-infectious fevers primarily manifest as central fevers, although in rare cases, they may also result from drug-induced causes.

Simplification and simulation of evaluation process for low efficiency constructed wetlands based on principal component analysis and machine learning.

Recent advances in the structure-based and ligand-based design of IKKβ inhibitors as anti-inflammation and anti-cancer agents.

NF-κB is a significant transcription factor that regulates the expression of various pro-survival genes. IKK is a crucial protein kinase that activates NF-κB translocating from cytoplasm to nucleus for DNA binding. It is composed of three subunits, IKKα, IKKβ, IKKγ (NEMO), where IKKα and IKKβ are catalytic subunits, and IKKγ is the regulatory subunit.

Insights into targeting NEMO for pharmacological regulation.

NF-κB essential modulator (NEMO), the non-catalytic regulatory subunit of the IκB kinase (IKK) complex, is essential for the canonical NF-κB activation pathway. It has been identified as a molecular platform for assembling the IKK complex and recruiting upstream IKK activators. However, the exact mechanism for regulating IKK activity has still remained elusive.

Insight into the intermolecular recognition mechanism between Keap1 and IKKβ combining homology modelling, protein-protein docking, molecular dynamics simulations and virtual alanine mutation.

Degradation of certain proteins through the ubiquitin-proteasome pathway is a common strategy taken by the key modulators responsible for stress responses. Kelch-like ECH-associated protein-1(Keap1), a substrate adaptor component of the Cullin3 (Cul3)-based ubiquitin E3 ligase complex, mediates the ubiquitination of two key modulators, NF-E2-related factor 2 (Nrf2) and IκB kinase β (IKKβ), which are involved in the redox control of gene transcription. However, compared to the Keap1-Nrf2 protein-protein interaction (PPI), the intermolecular recognition mechanism of Keap1 and IKKβ has been poorly investigated.
