Abstract
The development of novel pharmaceutical compositions, which are effective in the treatment of different inflammatory diseases and have a minimum number of side effects is very relevant. The aim of the present study was biochemical confirmation of anti-inflammatory activity of new pharmaceutical compositions comprising coxibs and caffeine. The level of conjugated dienes as primary products of lipid peroxidation has been evaluated in the plasma of rats at the acute inflammation caused by formalin. The white male rats of WAG line were used. The content of conjugated dienes was determined by spectrophotometric method. It was shown that combinations of caffeine and coxibs showed statistical significant decrease in the content of conjugated dienes in the rats’ blood plasma. Caffeine enriched anti-inflammatory action of coxibs effectively.

Abstract
Bone is a very dynamic tissue, subject to continuous renewal to maintain homeostasis through bone remodeling, a process promoted by two cell types: osteoblasts, of mesenchymal derivation, are responsible for the deposition of new material, and osteoclasts, which are hematopoietic cells, responsible for bone resorption. Osteomyelitis (OM) is an invasive infectious process, with several etiological agents, the most common being Staphylococcus aureus, affecting bone or bone marrow, and severely impairing bone homeostasis, resulting in osteolysis. One of the characteristic features of OM is a strong state of oxidative stress (OS) with severe consequences on the delicate balance between osteoblastogenesis and osteoclastogenesis. Here we describe this, analyzing the effects of OS in bone remodeling and discussing the need for new, easy-to-measure and widely available OS biomarkers that will provide valid support in the management of the disease.

Abstract
BACKGROUND Osteomyelitis (OM) is a local or generalised infection of the bone and bone marrow which may be multifactorial in its causation. In this study, we aimed to determine oxidative DNA damage and antioxidant status of patients with chronic osteomyelitis. MATERIAL METHOD In this study, patients with chronic osteomyelitis and healthy controls were compared for descriptive characteristics (age and gender) and serum levels of malondialdehyde (MDA), 8-hydroxy-2-deoxy guanosine and antioxidant enzymes catalase, glutathione and superoxide dismutase. RESULTS This was a case-control study. About 5 mL of venous blood was collected for the estimation of biochemical parameters. This study comprised of 36 OM patients diagnosed, and 41 healthy ages (25-55 years) and sex-matched individuals. Antioxidant enzyme levels were significantly lower in patients with OM, whereas MDA and oxidative DNA damage levels were significantly higher. CONCLUSION The results obtained from this study have shown that the oxidant-antioxidant balance is impaired in patients with chronic osteomyelitis. It also supports that chronic osteomyelitis has associated with oxidative DNA damage.

Abstract
Ionizing radiation leads to release of free radicals into the systemic circulation from irradiated tissues. These free radicals cause oxidative stress in distant organs. Oxidative status may be reversed by naturally occurring antioxidant agents. The aim of this study was to investigate protective and antioxidant effects of Nigella sativa oil (NSO) and thymoquinone (TQ) in kidney tissue of rats exposed to cranial irradiation. Forty-eight Sprague-Dawley rats were divided into six groups: IR group received irradiation (IR) to total cranium plus saline; IR plus NSO group received IR and NSO; IR plus TQ group received IR and TQ; sham group did not receive NSO, TQ or IR; control group of TQ received dimethyl sulfoxide; control group of NSO received saline. Total oxidant status (TOS), oxidative stress index (OSI) and lipid hydroperoxide (LOOH) levels were studied as oxidative parameters, and total antioxidant status (TAS), total sulfhydryl levels, paraoxonase (PON), ceruloplasmin (Cp) and arylesterase activities were determined as antioxidative parameters in the kidney tissue of rats. Kidney TOS, OSI and LOOH levels were significantly lower in IR plus TQ, IR plus NSO and sham groups compared to IR group (p < 0.001). TAS, PON and Cp activities in IR group were significantly lower compared to the control group (p < 0.001). PON and Cp activities were significantly higher in IR plus NSO and IR plus TQ groups compared to IR group (p < 0.001). In conclusion, free radicals generated by cranial ionizing radiation exposure cause oxidative stress in kidney. NSO and TQ exhibit protective and antioxidant effects against oxidative damage in rats.

Abstract
Purpose: To evaluate the antioxidant and radio-protective effects of Nigella sativa oil (NSO) and thymoquinone (TQ) on radiation-induced oxidative stress in brain tissue.Materials and methods: Fifty-four Sprague-Dawley rats were divided into six groups to test the radio-protective effectiveness of Nigella sativa oil and thymoquine administered by either orogastric tube or intraperitoneal injection. Appropriate control groups were also studied.Results: Brain antioxidant capacity, as measured by the levels of total superoxide scavenger activity (TSSA), non-enzymatic superoxide scavenger activity (NSSA), superoxide dismutase, paraoxonase (PON) activities, total antioxidant status and total sulfhydryl (-SH) group, were lower in the irradiation (IR) only group while xanthine oxidase (XO) activity, total oxidant status (TOS), oxidative stress index (OSI) and lipid hydroperoxide (LOOH) levels were higher in the group compared with all other groups. Brain glutathione-S-transferase (GST) activity significantly decreased in the IR only group when compared with the control groups. Glutathione peroxidase (GSH-Px) activity was lower in the IR only, NSO plus IR, TQ plus IR groups when compared with the control group of TQ. Arylesterase (ARYL) activity was not statistically significant in the IR only group compared with all other groups.Conclusions: The results suggest that Nigella sativa oil (NSO) and its active component, TQ, clearly protect brain tissue from radiation-induced oxidative stress.

Abstract
BACKGROUND AND AIM The thiol-disulfide homeostasis is essential for the body to maintain effective antioxidant defense mechanisms. We aimed to show the relationship between sepsis and thiol-disulfide homeostasis in newborns. MATERIALS AND METHODS In this prospective study, 66 newborns with sepsis (group 1) and 51 healthy controls (group 2) were included. In group 1, 53 newborns were diagnosed as clinical sepsis (group 1a) and 13 as definite sepsis (group 1b). The study has two time points; the day of diagnosis (step 1) and three days after the treatment (step 2). At step 1, group 1 and group 2 were compared for thiol-disulfide homeostasis as well as inflammatory markers. At step 2, the same laboratory tests were repeated only in group 1. RESULTS At step 1, the levels of C-reactive protein (CRP) and interleukin-6 (IL-6) were higher, while native thiol and total thiol levels were lower in group 1 compared to controls. Serum disulfide/total thiol ratio was also significantly higher in group 1. When analyzed for subgroups of group 1, demonstration of microorganism did not affect the serum thiol levels. Within group 1, at step 2, although CRP and IL-6 levels were significantly lowered compared to step 1, we did not observe significant changes in thiol-disulfide parameters. CONCLUSIONS The thiol-disulfide homeostasis may have a role in the pathogenesis of sepsis in newborns. The related parameters might be new markers for the diagnosis of sepsis in newborn patients. Further studies are needed to define the role of thiol-disulfide homeostasis in the course of neonatal sepsis.

Front Pharmacol 2019; 10:639.

Abstract
KR-12-a5 is an analogue of the antimicrobial peptide KR-12. Both of these two agents can play key effects in the treatment of infections such as osteomyelitis. Our previous work demonstrated that the osteogenic differentiation of human bone marrow mesenchymal stem cells (HBMSCs) can be enhanced by KR-12. The present study investigated if KR-12-a5 could reverse the adverse effects of lipopolysaccharides (LPS) on HBMSC osteogenesis and the involved molecular mechanisms. We observed the proliferation, cell cycle, and apoptosis of HBMSCs in the presence of KR-12-a5 by a cell counting kit-8 assay and flow cytometry. The osteogenic differentiation of HBMSCs was studied by alkaline phosphatase, Alizarin Red staining, and quantitative assays. Osteogenic differentiation marker levels were detected using real-time quantitative PCR analysis, which demonstrated that KR-12-a5 treatment reversed the inhibition of osteogenesis. Western blot analysis indicated that LPS-activated P38 mitogen-activated protein kinase (MAPK) signaling was inhibited and BMP/Smad pathway was reactivated after KR-12-a5 treatment under induced osteogenic conditions. Furthermore, flow cytometry results demonstrated that KR-12-a5 relieved LPS-induced oxidative stress. Combining the LPS-treated mouse model results, we proved that KR-12-a5 reversed the adverse effects of LPS on HBMSC osteogenic differentiation by influencing the BMP/Smad and P38 MAPK signaling pathways.

Abstract
Our study evaluated the synergistic impact of vancomycin and omega-3 fatty acids against osteomyelitis in a Staphylococcus aureus-induced rat model of osteomyelitis. The animals were grouped as follows: sham (group I), osteomyelitis (group II, control), vancomycin (20 mg/kg body weight, group III), omega-3 fatty acids (20 mg/kg body weight, group IV) and vancomycin (20 mg/kg body weight) + omega-3 fatty acids (20 mg/kg body weight) (group V). Lipid peroxidation, superoxide dismutase (SOD), glutathione peroxidase (Gpx), catalase, reduced glutathione (GSH), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were measured. The determination of bacterial growth and histopathological analyses were carried out. The lipid peroxidation, GSH, SOD, catalase and Gpx levels recovered to near-normal levels following combined treatment with vancomycin and omega-3 fatty acids. The TNF-α and IL-6 levels were reduced to near-normal levels. Combined supplementation with vancomycin and omega-3 fatty acids significantly reduced bacterial growth in bone and the implanted wire. Furthermore, the bone infection levels and histopathological score were reduced. In summary, combined treatment with vancomycin and omega-3 fatty acids was effective against bacterial growth and bone infection compared to monotherapy with vancomycin or omega-3 fatty acids.

Abstract
Osteomyelitis is a well-known bone infection in humans. The primary symptoms are fever, pain, weakness, and redness of the bone. l-Homocarnosine is a bioactive peptide abundant in brain and skeletal muscles. The present study evaluated the synergistic effect of vancomycin and l-homocarnosine against osteomyelitis in the Staphylococcus aureus-induced rat model of osteomyelitis. Animals were classified into the following groups: sham (group I), osteomyelitis (group II, control), vancomycin (25 mg/kg body weight, group III), l-homobrassinolide (25 mg/kg body weight, group IV), and vancomycin (25 mg/kg body weight) + l-homobrassinolide (25 mg/kg body weight) (group V). Lipid peroxidation, superoxide dismutase (SOD), glutathione peroxidase (Gpx), catalase, reduced glutathione (GSH), tumor necrosis factor-alpha (TNF-α) and interleukin-6 (IL-6) were determined. Assessments of bacterial growth and histopathological analyses were carried out. Lipid peroxidation, GSH, SOD, catalase, and Gpx levels recovered to near normal levels with the combined treatment of vancomycin and l-homocarnosine. TNF-α and IL-6 levels were reduced to near normal levels. Combined supplementation of vancomycin and l-homocarnosine reduced bacterial growth in bone and wire. Furthermore, bone infections and histopathological scores were also reduced. In summary, we showed that combined treatment of vancomycin and l-homocarnosine was more effective against bacterial growth and bone infection compared to monotherapy with vancomycin or l-homocarnosine.

Abstract
The differential diagnosis of Ewing sarcoma and osteomyelitis can be challenging and can lead to delays in treatment with possibly devastating results. In this retrospective, small-cohort study we demonstrate, that the Fourier Transformed Infrared (FTIR) spectra of osteomyelitis bone tissue can be differentiated from Ewing sarcoma and normal bone tissue sampled outside tumour area. Significant differences in osteomyelitis samples can be seen in lipid and protein composition. Supervised learning using a quadratic discriminant analysis classifier was able to differentiate the osteomyelitis samples with high accuracy. FTIR spectroscopy, alongside routine radiological and histopathological methods, may offer an additional tool for the differential diagnosis of osteomyelitis and ES.

Abstract
OBJECTIVE Thiol-disulphide homeostasis (TDH) has a critical role in various clinical disorders. We aimed to assess the association of TDH with acute tonsillopharyngitis (AT) in children. METHODS This study included 94 (73 viral and 21 bacterial) tonsillopharyngitis patients and 88 control children. Their native thiol, total thiol, and disulphide levels were measured. RESULTS Viral and bacterial tonsillopharyngitis patients had lower native thiol levels compared with healthy children (P < 0.001 and P = 0.008, respectively). Both groups had lower total thiol levels compared with control children (P = 0.002 for viral, P = 0.011 for bacterial). The disulphide levels were lower in bacterial than in viral tonsillopharyngitis patients (P = 0.04), and there was a significant difference between viral tonsillopharyngitis patients and the control group (P < 0.001). The native/total thiol ratio in each patient group was lower than in the control group (P < 0.001 for viral, P = 0.017 for bacterial). The disulphide/native thiol and disulphide/total thiol ratios were significantly higher in viral (P < 0.001 for both) and bacterial tonsillopharyngitis patients (P = 0.017 for both) than in healthy children. In all patients, a correlation was found between the levels of C-reactive protein (CRP) and native thiol (r = -0.211, P = 0.04), CRP and total thiol (r = -0.217, P = 0.036), white blood cell (WBC) and native thiol (r = -0.228, P = 0.002), WBC and total thiol (r = -0.191, P = 0.01), and WBC and disulphide (r = 0.160, P = 0.03). DISCUSSION TDH is altered in AT in children. The alteration is more prominent in viral than in bacterial tonsillopharyngitis.

Abstract
Our aim was to evaluate effect of etanercept on oxidative stress parameters in rats with experimental peritonitis and investigate the availability of etanercept usage in the treatment of peritonitis in the future. Twenty-eight rats were divided into four groups as control (group 1), peritonitis (group 2), peritonitis + cefazolin sodium (group 3), and peritonitis + cefazolin sodium + etanercept (group 4). Peritoneal tissue and blood samples were taken from all of the rats for histopathological and biochemical examination. The oxidative stress parameters were examined in blood and tissue samples. It was observed that rats with peritonitis benefit from cefazolin sodium treatment. Evaluating the effectiveness of etanercept was our main objective for this study. In this perspective, we compared group 3 and group 4 and found statistically significant decreases in oxidative parameters and statistically significant increases in antioxidants in serum and tissue samples in group 4. It is observed that there was a significant contribution of etanercept on biochemical and also histopathological results. As a result, the TNF-α inhibitor, etanercept, in addition to antibiotics given in the early treatment of peritonitis results in more significant improvement of histopathological and oxidative parameters as compared to antibiotics alone.

Abstract
INTRODUCTION Osteomyelitis (OM) is a local or generalized infection of the bone and bone marrow which may be multifactorial in its causation. Chronic infection is characterised by sequestrum and involucrum formation. AIM The present study has been carried out for assessing the oxidative stress in chronic OM by measurement of serum oxidants {such as malondialdehyde (MDA), protein carbonyl (PC), nitrite} and the serum antioxidants {such as ascorbic acid, superoxide dismutase (SOD), ceruloplasmin (Cp), blood glutathione} by spectrophotometric method. MATERIALS AND METHODS This was a case control study. About 5 ml of venous blood was collected for the estimation of biochemical parameters. This study comprised of 50 OM patients diagnosed at SSLH Hospital, Varanasi and 50 healthy ages (15-35 y) and sex matched individuals. RESULTS Significantly increased (p<0.0001) levels of serum oxidants and significantly decreased (p<0.0001) levels of all serum antioxidants except ceruloplasmin indicated significantly increased (p<0.0001) levels in response to infections in chronic OM patients as compared to the healthy controls. CONCLUSION These results suggest that there occurs an imbalance between oxidants and antioxidants, especially an increase in oxidative stress, as measured by the levels of the parameters: serum MDA, serum protein carbonyl and serum nitrite.

Sequential analysis of oxidative stress markers and vitamin C status in acute bacterial osteomyelitis. Mediators Inflamm 2014; 2014:975061.

Abstract
In bacterial bone infections, excessively formed oxidants may result in local and systemic oxidative stress. Vitamin C is the major extracellular nonenzymatic antioxidant, also implicated in bone cells metabolism and viability. The physiological functions of vitamin C largely depend on its redox status. We sequentially assessed oxidative stress markers, hydroperoxides and malondialdehyde (MDA), total antioxidant activity (AOA), total vitamin C, ascorbic acid (Asc), and oxidized/reduced vitamin C ratio in 137 patients with acute osteomyelitis (OM). Compared to 52 healthy controls, in OM group baseline serum hydroperoxides, MDA and oxidized/reduced vitamin C ratio were higher whilst Asc and AOA were lower (P < 0.05, resp.). On the other side, total vitamin C levels in patients and controls were similar (P > 0.05), thereby suggesting a relative rather than absolute vitamin C deficiency in OM. During the follow-up, oxidative stress markers, AOA, and oxidizedreduced vitamin C ratio were gradually returned to normal, while there was no apparent change of total vitamin C concentrations. Persistently high values of oxidized/reduced vitamin C ratio and serum MDA were found in subacute OM. In conclusion, acute OM was associated with enhanced systemic oxidative stress and the shift of vitamin C redox status towards oxidized forms.
