Abstract Background Sepsis is a life-threatening organ dysfunction resulting from dysregulated host response to infection. Due the high mortality rates and treatment costs associated with sepsis, research focusing on innovative strategies replace one dimensional approaches. Recent studies are being conducted use of immunotherapeutics in sepsis impact timing. This study aimed elucidate significance timing immunotherapy Tocilizumab (TCZ) implications differences Methods LPS-induced model was...

This study investigated the synergistic protective effects of melatonin (MEL) and ascorbic acid (vitamin C, ASA) in treating sepsis-induced lung injury rats. Rats were divided into five groups: control, cecal ligation puncture (CLP), CLP + MEL, ASA MEL ASA. The (10 mg/kg), (100 mg/kg) their combination on oxidative stress, inflammation histopathology evaluated septic rats' tissues. Sepsis-induced stress evident through increased levels malondialdehyde (MDA), myeloperoxidase (MPO), total...

Sepsis is an uncontrolled systemic infection, withcomplex pathophysiology that may result in acute lung organ damage and cause multiple failure. Although much research has been conducted to illuminate sepsis's complex pathophysiology, sepsis treatment protocols are limited, remains important of mortality andmorbidity intensive care units.Various studies have shown idebenone (IDE) possesses strong antioxidant properties, which inhibit lipid peroxidation protect cells from oxidative damage....

In the last two decades, fluorescent carbon quantum dots (CQDs) have attracted intense interest as a new nanomaterial with unique properties. This material offers significant advantages compared conventional dyes and inorganic QD systems, is used extensively in many different fields, especially bioimaging sensor applications. Despite all positive values they offer, production of CQD systems excitation wavelength-dependent nature high yield (QY) still scientific challenge. this study, we...

This study aims to investigate the protective effect of roflumilast, a phosphodiesterase (PDE)-4 enzyme inhibitor, and demonstrate its possible role in development prevention cerebral ischemia/reperfusion injury (CI/RI) after stroke induced by carotid artery ligation juvenile rats. The rats were randomly divided into five groups: healthy group without any treatment, administered with 1 mg/kg CI not 0.5 roflumilast. In groups, reperfusion was achieved 2h ischemia induction; roflumilast this...

A sepsis model was created, induced by cecal ligation and puncture (CLP), in juvenile rat groups. Milrinone (MIL), which is known to have a modulatory effect on pro-inflammatory cytokines, administered the designated groups early period before severe developed. The study aimed at investigating possible protective effects of milrinone lung kidney tissues rats late phase sepsis.The pups were divided into seven with six animals each group: (1) healthy who received no drug; (2) CLP-S12...

The study aimed to evaluate serum interleukin-28 levels in COVID-19 patients and correlate the results with disease severity.This included 90 who presented outpatient clinics, hospital wards, intensive care units. Serum interleukin-28, C-reactive protein, lactate dehydrogenase, fibrinogen, d-dimer, ferritin were measured. Patients divided into 3 groups based on clinical severity mild, moderate, severe (each group consisted of 30 patients).There significant differences ferritin, interleukin-...

Acute lung injury (ALI) is an inflammation of the that results in increased vascular permeability, and can be caused by many different phenomena including COVID-19. Boron compounds have led to strong inhibition release inflammatory cytokines decrease coagulation factors both contributes COVID-19 related injury. So, this study, we investigate molecular histopathological effects inhaler boron use on LPS-induced ALI. In study ALI induced rats with LPS administration. Different doses inhaled...
