Excessive activation of the innate immune system often leads to fatal consequences and can be considered as one of the phenoptotic events. After traumatic injury, various components of mitochondria are released into the circulation and stimulate myeloid cells of the innate immunity. Presumably, mitochondrial DNA (mtDNA) might activate immune cells (Zhang, Q., et al. (2010) Nature, 464, 104-107). In the present study, we investigated the role of mtDNA as a direct activator of human neutrophils, as well as a prognostic marker in patients with severe trauma. Quantitative determination of mtDNA in the plasma of these patients revealed its significant increase (p < 0.02) in the group of survivors compared to non-survivors. Highly purified mtDNA was not able to induce activation of human neutrophils, thus possibly indicating the existence of additional factor(s) ensuring the recognition of mtDNA as a damage-associated molecular pattern.

In this article, we comment on the article by Cheng published in recently. Posthepatectomy liver failure (PHLF) remains a leading cause of hepatectomy-related mortality and can be evaluated according to liver reserve function. Liver stiffness (LS) measured by ultrasonic elastography and spleen area demonstrate a strong correlation with hepatic proliferation, fibrosis, and portal vein congestion, thus indirectly reflecting liver reserve function.

is a prevalent fungal pathogen responsible for infections in humans. As described recently, nanometer-sized extracellular vesicles (EVs) produced by play a crucial role in the pathogenesis of infection by facilitating host inflammatory responses and intercellular communication. This study investigates the functional properties of EVs released by biofilms formed by two strains-3147 (ATCC 10231) and SC5314-in eliciting host responses.

Objective: The aim of this study was to examine the levels of hematologic parameters in acute ischemic stroke (AIS) and transient ischemic attack (TIA) and to evaluate the use of Neutrophil/Lymphocyte ratio (NLR), Systemic Immune-Inflammation Index (SII), and systemic inflammation response index (SIRI) in the differentiation of AIS and TIA.
Materials And Methods: Data and hematological results of patients admitted to the emergency department and diagnosed with AIS and TIA were compared retrospectively.
Results: The study included 36 TIA patients (M/F = 15/21) with a mean age of 64.

Bacterial meningitis is a severe and life-threatening infection of the central nervous system (CNS), primarily caused by and . This condition carries a high risk of mortality and severe neurological sequelae, such as cognitive impairment and epilepsy. Pain, a central feature of meningitis, results from the activation of nociceptor sensory neurons by inflammatory mediators or bacterial toxins.

Background: Dyslipidemia presents in various autoimmune diseases, and the serum lipid profile in systemic lupus erythematosus (SLE) has not yet been clearly defined. This study aims to evaluate the level of serum lipids in patients with SLE.
Methods: A case-control study evaluated four conventional sera lipids-total cholesterol (TC), triglyceride (TG), high-density lipoprotein (HDL), and low-density lipoprotein (LDL)-in patients with SLE compared to healthy controls (HCs).
