Introduction: Inflammation plays a role in coronavirus disease 2019 (COVID-19) pathophysiology and anti-inflammatory drugs may help reduce the disease severity. Levamisole is an anthelmintic drug with immunomodulatory and possible antiviral effects. This study aimed to evaluate the role of levamisole in the treatment of patients with COVID-19.

Analysis of the protective effect of hydrogen sulfide over time in ischemic rat skin flaps.

Ann Chir Plast Esthet

January 2025

Department of Plastic, Reconstructive, and Aesthetic Surgery, Faculty of Medicine, Çukurova University, Adana, Turkey.

Background: Hydrogen sulfide (HS) is a widely studied gasotransmitter, and its protective effect against ischemia-reperfusion damage has been explored in several studies. Therefore, a requirement exists for a comprehensive study about HS effects on ischemia-reperfusion damage in flap surgery. The aim of this study is to examine the effect of hydrogen sulfide by creating ischemia-reperfusion injury in the vascular-stemmed island flap prepared from the rat groin area.

Background: Changes in cerebral blood flow (CBF) may contribute to the initial stages of the pathophysiological process in patients with Alzheimer's disease (AD). Hypoperfusion has been observed in several brain regions in patients with mild cognitive impairment (MCI). However, the clinical significance of CBF changes in the early stages of AD is currently unclear.

Mycoplasma pneumoniae drives macrophage lipid uptake via GlpD-mediated oxidation, facilitating foam cell formation.

Int J Med Microbiol

January 2025

Division of Microbiology, Department of Infectious Medicine, Kurume University School of Medicine, 67 Asahi-machi, Kurume 830-0011, Japan.

Cardiovascular diseases, primarily caused by atherosclerosis, are a major public health concern worldwide. Atherosclerosis is characterized by chronic inflammation and lipid accumulation in the arterial wall, leading to plaque formation. In this process, macrophages play a crucial role by ingesting lipids and transforming into foam cells, which contribute to plaque instability and cardiovascular events.

Non-invasive estimation of pressure differences using 2D synthetic aperture ultrasound imaging offers a precise, low-cost, and risk-free diagnostic tool. Unlike invasive techniques, this preserves natural blood flow and avoids the limitations of devices that occupy lumen space. This paper evaluates a previously published estimator, modified to incorporate Singular Value Decomposition (SVD) echo-cancellation, using data from ten healthy volunteers and one patient.
