Abstract

Lipopolysaccharide (LPS) is a major component of a gram-negative bacterial wall that is widely used and well-established to induce inflammation in vitro. In addition, the in vitro model using RAW 264.7 cells is the most commonly applied in screening the anti-inflammatory and elucidating the pathophysiology of inflammation-based disease, as well.  However, there is still limited data on the efficacy of different doses of LPS in inducing inflammation in RAW 264.7 cells. This study aimed to evaluate the effect and safety of LPS at various doses in RAW 264.7 cells. RAW 264.7 cells were exposed to LPS at different dose ranges (10ng/mL-10µg/mL) for 24 hours. The nitric oxide (NO) release as inflammatory responses and viability test were evaluated using Griess assay and CCK-8 assays, respectively. The result showed that NO production was increased at different doses of LPS compared to the control although not significant. Whereas, All LPS-treated RAW 264.7 cells tended to increase but not significantly compared to the control groups. This study showed that the LPS treatment effectively induced inflammation in RAW 264.7 cells as shown by NO production and was considerably safe as the viability was comparable between LPS and control group for RAW cells 264.7 at least up to 10µg/mL for 24 hours.

Abstract

Background: Supraventricular tachycardia (SVT) and coronary artery disease (CAD) are common cardiovascular diseases that can exist simultaneously, complicating diagnosis and treatment. This case series aims to present clinical scenarios and management strategies in patients with both conditions, emphasizing the decision-making process between ablation and revascularization. Case Presentations: Three male patients, between 51 and 63 years old, presented with recurrent palpitations which sometimes accompanied by chest discomfort or exertional dyspnea. All patients had cardiovascular risk factors. Angiography revealed either multivessel CAD or a history of percutaneous coronary intervention (PCI). Electrocardiogram (ECG) showed different tachyarrhythmias which included atrioventricular nodal reentrant tachycardia (AVNRT), atrial tachycardia (AT), and Wolff-Parkinson-White (WPW) syndrome. The management strategies depended on the main clinical issue present. The treatment of patients with significant ischemia involved PCI with drug-eluting stents (DES) to achieve both symptom relief and rhythm stabilization. On the contrary, when arrhythmia was the main driver of symptoms, catheter ablation successfully eliminated the tachyarrhythmia and enhanced the quality of life. Conclusions: Adequate diagnosis of arrhythmia, its underlying mechanisms, substrates, and triggers by use of electrophysiological study is crucial for well-adapted, multidisciplinary selection of intervention—catheter ablation, PCI, or both—as key to clinical best results.
