Regulatory cytokines prescribe the outcome of the inflammation in the process of pseudoexfoliation production.

Background: The purpose of this study is to reveal the participation of different regulatory cytokines within the process of pseudoexfoliation (PEX).

Methods: Our study included 140 patients referred to cataract surgery with early and late stage of pseudoexfoliation syndrome (XFS) or pseudoexfoliation glaucoma (XFG). Humor and serum levels of cytokines: transforming growth factor beta (TGF-β), platelet-derived growth factor (PDGF), epidermal growth factor (EGF), insulin-like growth factor (IGF), IL-8 and interferon-inducible T cell alpha chemoattractant (ITAC) were measured in a sample using high sensitivity enzyme-linked immunoabsorbent assay (ELISA) kit.

Preconditioning with hyperbaric oxygen and calcium and potassium channel modulators in the rat heart.

The aim of this study was to establish the effect of combined therapy with hyperbaric oxygen (HBO2) therapy and verapamil, amlodipine or nicorandil on functional recovery and oxidative stress markers after ischemia in the isolated rat heart. The study included 48 rats (Wistar albino, male gender, eight weeks old, body weight 200±50g). All animals were exposed to HBO2 treatment over 14 days.

The influence of folic acid-induced acute kidney injury on cardiac function and redox status in rats.

The aim of this study was to evaluate the influence of acute kidney injury caused by high doses of folic acid on cardiac function and markers of oxidative stress in serum and isolated rat heart. Isolated hearts of Wistar albino rats (divided into two groups: control and folic acid group) were perfused according to Langendorff technique at basal coronary perfusion pressure CPP of 70 cm HO. After a stabilization period, CPP was lowered to 60 cm HO and then gradually increased to 80, 100, 120 and finally decreased to 40 cm HO in order to establish coronary autoregulation.

Galectin-3 Regulates Indoleamine-2,3-dioxygenase-Dependent Cross-Talk between Colon-Infiltrating Dendritic Cells and T Regulatory Cells and May Represent a Valuable Biomarker for Monitoring the Progression of Ulcerative Colitis.

Galectin-3 regulates numerous biological processes in the gut. We investigated molecular mechanisms responsible for the Galectin-3-dependent regulation of colon inflammation and evaluated whether Galectin-3 may be used as biomarker for monitoring the progression of ulcerative colitis (UC). The differences in disease progression between dextran sodium sulphate-treated wild type and Galectin-3-deficient mice were investigated and confirmed in clinical settings, in 65 patients suffering from mild, moderate, and severe colitis.

The Effects of Thiamine Hydrochloride on Cardiac Function, Redox Status and Morphometric Alterations in Doxorubicin-Treated Rats.

Previous studies have suggested that thiamine has antioxidant activity and could decrease the production of ROS in various disorders. Our study focused on the effect of thiamine hydrochloride in the reversal of DOX-induced cardiotoxicity and compared it with the reversal in the absence of thiamine pre-treatment. Rats were divided into groups as follows: (a) thiamine + doxorubicin (TIA + DOX), (b) doxorubicin (DOX) and c) healthy (CTRL) groups.

Suffering from Cerebral Small Vessel Disease with and without Metabolic Syndrome.

Background: Cerebral small vessel disease (CSVD) and metabolic syndrome were separately associated with cognitive impairment and depression. However, whether metabolic syndrome adds to cognitive impairment and depression in patients who already have CSVD remained unanswered.

Objective: The aim of our study was to investigate the association of metabolic syndrome with cognitive impairment and depression in patients with CSVD who have lacunar lesions or white matter hyperintensities.

Viable C5 and C6 Proximal Stump Use in Reconstructive Surgery of the Adult Brachial Plexus Traction Injuries.

Background: In patients with only upper (C5, C6) brachial plexus palsy (BPP), the pooled international data strongly favor nerve transfers over nerve grafts. In patients with complete BPP, some authors favor nerve grafts for the restoration of priority functions whenever there is a viable proximal stump.

Objective: To evaluate functional recovery in cases of upper and complete BPP where only direct graft repair from viable proximal stumps was performed.

Hypertension in Polycystic Ovary Syndrome: Novel Insights.

Polycystic ovary syndrome (PCOS) is a common endocrine disease in women during reproductive age. It was shown that PCOS women are with high risk for dyslipidemia, glucose intolerance, type 2 diabetes and metabolic syndrome. These factors are considered to represent traditional risk factors for the occurrence of cardiovascular disease.

Background: Bucindolol is a beta-blocker whose unique pharmacologic properties provide greater benefit in HF patients with reduced ejection fraction (HFrEF) who have the beta-adrenergic receptor (ADRB1) Arg389Arg genotype.

Methods: A total of 267 HFrEF patients with a left ventricular ejection fraction (LVEF) <0.

Biomarkers for the prediction of early pulmonary embolism related mortality in spontaneous and provoked thrombotic disease.

Factors associated with provoked PE may influence a biomarker's predictive value for the primary outcome. The aim of this study was to investigate the value of BNP, cTnI, CRP and D-Dimer measurements taken soon after hospital admission for the prediction of 30-day PE-caused death in patients with spontaneous versus provoked PE.Data were extracted from a pool of 726 consecutive PE patients enrolled in the multicenter Serbian PE registry.

Impact of epilepsy duration, seizure control and EEG abnormalities on cognitive impairment in drug-resistant epilepsy patients.

Cognitive impairment frequently occurs in epilepsy patients. Patients with drug-resistant epilepsy (DRE) have poor drug responsivity and higher seizure frequency which consequently lead to brain damage and may have implications on cognitive status. In the present study, we assessed a frequency and degree of cognitive impairment in 52 patients with drug-sensitive epilepsy (DSE) and 103 DRE patients at three time points (baseline, after 12 and 18 months).

Nonalcoholic Fatty Liver Disease in Patients with Polycystic Ovary Syndrome.

Polycystic ovary syndrome (PCOS) is the most common endocrine disease in women during the reproductive period. True PCOS phenotype is prone to develop metabolic consequences during life. Obese PCOS women with insulin resistance are carrying a risk for developing type 2 diabetes, and influencing liver function by generating liver steatosis and nonalcoholic fatty liver disease (NAFLD).

Pharmacokinetics of Vancomycin in Patients with Different Renal Function Levels.

There are many determinants of vancomycin clearance, but these have not been analyzed separately in populations with different levels of renal function, which could be why some important factors have been missed. The aim of our study was to compare the pharmacokinetic parameters and factors that may affect vancomycin pharmacokinetics in groups of patients with normal renal function and in those with chronic kidney failure. The study used a population pharmacokinetic modeling approach, based on plasma vancomycin concentrations and other data from 78 patients with chronic kidney failure and 32 patients with normal renal function.

Fractional Flow Reserve and Quality-of-Life Improvement After Percutaneous Coronary Intervention in Patients With Stable Coronary Artery Disease.

Background: Whether the benefit in quality of life (QOL) after percutaneous coronary intervention depends on the severity of the stenosis as determined by fractional flow reserve (FFR) remains unknown. This study sought to investigate the relationship between FFR values and improvement in QOL.

Methods: From the FAME 1 and 2 trials (Fractional Flow Reserve Versus Angiography for Multivessel Evaluation), we identified 706 stable patients with coronary artery disease who had at least 1 lesion with an FFR≤0.

A five-compartment biokinetic model for Y-DOTATOC therapy.

Purpose: Neuroendocrine tumors (NETs) are now routinely treated by radiopeptide targeted therapy using somatostatin receptor-binding peptides such as Y- and Lu-DOTATOC. The objective of this work was to develop a biokinetics model of Y labelled DOTATOC, which is applied in the therapy of NETs to estimate doses in kidney and tumor.

Methods: A multi-compartment model described by two sets of differential equations, one set for the actual 30-min infusion and the other set for the post-infusion period was developed and activities were measured by liquid scintillation counting in blood (compartment 1) and the urine (compartment 3).

Oxidative stress and neuroinflammation should be both considered in the occurrence of fatigue and depression in multiple sclerosis.

Oxidative stress and neuroinflammation have a role in the pathogenesis of multiple sclerosis (MS) and in depression. Fatigue is the most disabling symptom in patients with MS and could also be a part of depressive symptomatology. In this study, we measured the serum levels of uric acid (UA) as a marker of oxidative stress and C-reactive protein (CRP) as an inflammatory marker, in 98 patients with MS in relapse and remitting phase of illness and 35 healthy subjects.

Indoleamine 2,3-dioxygenase-dependent expansion of T-regulatory cells maintains mucosal healing in ulcerative colitis.

Background: Dendritic cell (DC)-derived indolamine 2,3-dioxygenase (IDO) degrades tryptophan to kynurenine, which promotes conversion of inflammatory T cells in immunosuppressive regulatory T cells (Tregs). We analyzed the significance of the IDO:Treg axis for inducing and maintaining mucosal healing in ulcerative colitis (UC).

Methods: Dextran sodium sulphate (DSS)-induced colitis in BALB/c mice (model for mucosal healing) and C57BL/6 mice (model for persistent disease) was used.

Neutrophil-to-Lymphocyte Ratio, Monocyte-to-Lymphocyte Ratio, Platelet-to-Lymphocyte Ratio, and Mean Platelet Volume-to-Platelet Count Ratio as Biomarkers in Critically Ill and Injured Patients: Which Ratio to Choose to Predict Outcome and Nature of Bacteremia?

Background: Neutrophil-to-lymphocyte ratio (NLR), monocyte-to-lymphocyte ratio (MLR), platelet-to-lymphocyte ratio (PLR), and mean platelet volume-to-platelet count (MPV/PC) ratio are readily available parameters that might have discriminative power regarding outcome. The aim of our study was to assess prognostic value of these biomarkers regarding outcome in critically ill patients with secondary sepsis and/or trauma.

Methods: A total of 392 critically ill and injured patients, admitted to surgical ICU, were enrolled in a prospective observational study.
