Cox protein plays a critical role in deciding the lytic-lysogenic switch of P2 enteric phages. This phenomenon makes Cox protein one of the most important candidates in developing novel phage-based therapeutics against antibacterial resistant pathogens. The principle focus concerning protein and its decision making is a DNA binding event, which helps to regulate differential promoter expression. In the current study, we have attempted to understand the sequence, structural and dynamic features associated with Cox protein and its DNA binding. Unavailability of information was a big burden in further proceedings. We have done an extensive literature search to develop a database of Cox with relevant information. That information coupled with the methods of Sequence-based phylogenetic and conservation studies, Homology Modelling, Atomic-level Docking and Molecular Dynamics (MD) Simulation (50 ns each for 10 systems, i.e. total of 500 ns) were performed in the current study. Analysis of those extensive studies has provided us the required sequence to structure to dynamics to functional understanding. Our present study would indeed be very helpful in understanding the biochemical mechanism of Cox activation as well as designing potential phage therapeutics.

Objectives: To explore the role of newly emerging autoantibodies (AAbs) - peptidyl-arginine deiminase 4 (aPAD4), carbamylated proteins (aCarP), and anti-RA33 (aRA33) - alongside the traditionally assessed rheumatoid factor (RF) and anti-citrullinated protein antibodies (ACPA), in predicting the response to abatacept (ABT) and its retention rate in rheumatoid arthritis (RA) patients.
Methods: Data from 121 consecutive ABT-treated RA patients were recorded. The RF and ACPA status were retrospectively assessed by reviewing the patients' clinical records.

Persistent organic pollutants (POPs) are a group of organic chemical compounds. Contradictory results have emerged in epidemiological studies attempting to elucidate their relationship with breast cancer risk. This study explored the relationship between dietary exposures to multiple POPs and ER-positive breast cancer risk in the French E3N cohort study, using three different approaches to handle multicollinearity among exposures.

Exposure to particulate matter (PM) in the air harms human health. Most studies on particulate matter's (PM) effects have primarily focused on respiratory and cardiovascular diseases. Recently, IL-32θ, one of the IL-32 isoforms, has been demonstrated to modulate cancer development and inflammatory responses.

Objective: To investigate baseline and change of pulmonary damage biomarkers (serum Krebs von den Lungen 6 [KL-6], human surfactant protein D [hSP-D], and matrix metalloproteinase 7 [MMP-7]) with rheumatoid arthritis-associated interstitial lung disease (RA-ILD) progression.
Methods: In the Korean Rheumatoid Arthritis Interstitial Lung Disease (KORAIL) cohort, a prospective cohort, we enrolled patients with RA and ILD confirmed by chest computed tomography imaging and followed annually. ILD progression was defined as worsening in physiological and radiological domains of the 2022 American Thoracic Society, European Respiratory Society, Japanese Respiratory Society, and Latin American Thoracic Society guideline for progressive pulmonary fibrosis (PPF).
Association between abatacept exposure levels and infection occurrence in patients with rheumatoid arthritis: post hoc analysis of the AVERT-2 study.

Dr Daphne Williams, PharmD, Bristol Myers Squibb, Princeton, NJ, USA.
Objective: To determine if higher serum exposure during subcutaneous (SC) abatacept treatment was associated with an increased infection risk in adult patients with early rheumatoid arthritis (RA).
Methods: Data from AVERT-2 (Assessing Very Early Rheumatoid arthritis Treatment-2, NCT02504268), a randomized, placebo-controlled study in anticitrullinated protein antibody- positive patients with early RA, were analyzed. A post hoc population pharmacokinetic (PPK) analysis was performed.
