Abstract

Background. One of the regenerative therapy modalities in Parkinson is using the beta glucan effect contained in Saccharomyces cerevisae.Objective. To identify the effect of reduction in alpha synuclein expression on the brain substantia nigra in Parkinson's rat model after given Saccharomyces cerevisae. Methods. This research applied true experimental design by in vivo with draft randomized post test only controlled group design. The sample was divided into five groups, each of them consisted of 5 rats. Variables measured were the decreasing level of alpha synuclein. Results. There was a significant difference between positive control and negative control group.Conclusion. The addition of Saccharomyces cerevisae is able to lower the alpha synuclein expression in Parkinson’s Wistar strain rat models significantly with maximum at the dose of 72 mg/kgBB.

Abstract

BACKGROUND Angiotensin-converting enzyme 2 (ACE2) has a role in SARS-CoV-2 incidence, and digoxin is a competitive inhibitor of SARS-CoV-2-ACE2 binding. This study aimed to investigate the effects of digoxin on SARS-CoV-2-ACE2 binding, proinflammatory cytokines, and prothrombotic factors in adipocytes of patients with COVID-19. METHODS This in vitro study used adipocyte cultures, which were divided into negative control, positive control (SARS-CoV-2 S1 spike protein only), SARS-CoV-2 S1 spike protein with digoxin, and SARS-CoV-2 S1 spike protein with human recombinant soluble ACE2 (hrsACE2). Data were analyzed using one-way ANOVA and Pearson correlation. RESULTS SARS-CoV-2 significantly elevated ACE2 and increased interleukin (IL)-6, tumor necrosis factor-alpha (TNF-α), tissue factor (TF), and plasminogen activator inhibitor-1 (PAI-1) compared to the negative control group (p<0.001). No SARS-CoV-2-ACE2 binding was detected in SARS-CoV-2 with digoxin and hrsACE2 groups, compared to the positive control group (0 ng/ml versus 0 ng/ml versus 36.33 [1.58] ng/ml, p<0.001). Digoxin significantly decreased IL-6 (48.94 [1.80] ng/ml versus 90.93 [4.29] ng/ml; p<0.001), TNF-α (87.65 [6.88] ng/ml versus 307.95 [57.34] ng/ml; p<0.001), TF (5.33 [0.32] ng/ml versus 6.85 [0.22] ng/ml; p<0.001), and PAI-1 levels (2.92 [0.168] ng/ml versus 4.86 [0.11] ng/ml; p<0.001), compared to positive control group. ACE2 positively correlated with IL-6 (p = 0.004, r = 0.763) and TF (p = 0.004, r = 0.768) but was not correlated with IL-1β, TNF-α, and PAI-1 levels. CONCLUSIONS This study promoted digoxin therapy to prevent cytokine storm and thromboembolism by decreasing IL-6, TNF-α, TF, and PAI-1 in adipocyte cultured models at an early stage of COVID-19.

Abstract

Background: It is imperative to diagnose and treat acute coronary occlusion as soon as possible, especially in patients with complicated conduction anomalies. Although electrocardiography (ECG) is still the gold standard for diagnosis, it has drawbacks, particularly when conduction abnormalities such as bundle branch block are present. Case Summary:  In this case study, a 60-year-old woman with cardiovascular risk factors and type 2 diabetes had an anteroseptal STEMI that was worsened by RBBB and total AV block. The patient's recovery was complicated by extensive gastrointestinal bleeding after a successful percutaneous coronary intervention (PCI) and the implantation of a stent in the left anterior descending artery. Conclusion: In addition to highlighting the difficulties of striking a balance between dual antiplatelet therapy (DAPT) and reperfusion strategies in a high bleeding risk setting, this also highlights the management of a high-risk STEMI patient with total atrioventricular (AV) block, right bundle branch block (RBBB), and severe gastrointestinal complications. -- Highlights: 1. This case illustrates the complex management of STEMI with total AV block and right bundle branch block, where urgent PCI and temporary pacing achieved rapid hemodynamic stabilization. 2. Post-PCI gastrointestinal bleeding under dual antiplatelet therapy highlights the need for individualized antithrombotic strategies and vigilant post-discharge monitoring in high-risk patients.
