Abstract: Rheumatoid arthritis is an inflammatory autoimmune disorder.: CIA rats were treated by using three doses of WSAq (100, 200, 300 mg/kg b. wt., orally) and methotrexate (MTX, 0.25 mg/kg b. wt. i.p.) as a standard reference drug for 20 days. The anti-arthritic effect was assayed by measuring the arthritic index, autoantibodies such as rheumatoid factor (RF), anti-cyclic citrullinated peptide antibody (a-CCP), anti-nuclear antibody (ANA), anti-collagen type II antibody (a-CII) and inflammatory marker like C-reactive protein (CRP). The oxidative stress parameters were also measured.: Treatment with WSAq resulted in a dose-dependent reduction in arthritic index, autoantibodies and CRP (p<0.05) with maximum effect at dose of 300 mg/kg b. wt. and the results were comparable to that of MTX-treated rats. Similarly, oxidative stress in CIA rats was ameliorated by treatment with different doses of WSAq, as evidenced by a decrease in lipid peroxidation and glutathione-: The results showed that WSAq exhibited antioxidant and anti-arthritic activity and reduced inflammation in CIA rats and suggests the potential use of this plant in the treatment of arthritis.

Backgound: The generation of oxidative stress can be referred to Aluminium toxic effect in animals and humans. This study aimed to evaluate the role of broccoli (Br) and beetroot (Be) extarcts as antioxidant that prevents oxidative stress that associated with aluminum toxicity. Materials and Methods: Fifty Wister female rats were grouped into five groups (each 10 rats): Group 1: control group, administered drinking water only. Group 2: (Neurogenerative) which were induced by oral administration of aluminum chloride (20 mg/kg b.w) daily for one month. Group 3: Rats given aluminum chloride were treated with Rivastigmine (Ri) (1 mg/kg b.w) as a reference drug daily for five weeks. Group 4: Rats given aluminum chloride were treated with beet root extract (50 mg/kg b.w) daily for six weeks. Group 5. Rats given aluminum chloride were treated with broccoli extract (50 mg/kg b.w) daily for five weeks. Results: (AlCl3) group showed a significant increase in Ach level (P<0.05) and a non-significant change in DOP and NE levels compared to control. (AlCl3+Be) was non-significant (P˂0.05) change in Ach, DOP and NE levels compared to (AlCl3) group and showed a significant (P<0.05) increase in Ach level compared to control. (AlCl3+Br) showed a significant (P<0.05) increase in NE level and non-significant (P˂0.05) change in Ach and DOP levels compared to (AlCl3) group. (AlCl3+Ri) showed a significant (P<0.05) increase in Ach, DOP and NE levels compared to (AlCl3) group. Also, showed a significant (P<0.05) increase in Ach and NE compared to control. Conclusion: Neuroprotective role of broccoli in the present study which may result from its antioxidant properties due to its bioactive content such as glucosinolate, isothiocyanate, Sulforaphane, and flavonoids. Therefore, Broccoli can have a favorable effect on neurotoxicity due to their antioxidant and anti-inflammatory properties.

Sciatic nerve injury is often associated with neuropathic pain and neuroinflammation in the central and peripheral nervous systems. In our previous work, Potamogeton perfoliatus L. displayed anti-inflammatory, antipyretic and analgesic properties, predominantly via the inhibition of COX-2 enzyme and attenuation of oxidative stress. Herein, we extended our investigations to study the effects of the plant’s extract on pain-related behaviors, oxidative stress, apoptosis markers, GFAP, CD68 and neuro-inflammation in sciatic nerve chronic constriction injury (CCI) rat model. The levels of the pro-inflammatory marker proteins in sciatic nerve and brainstem were measured with ELISA 14 days after CCI induction. Pretreatment with the extract significantly attenuated mechanical and cold allodynia and heat hyperalgesia with better potential than the reference drug, pregabalin. In addition, CCI lead to the overexpression of prostaglandin E2 (PGE2), inducible nitric oxide synthase (iNOS), tumor necrosis alpha (TNFα), nuclear factor κB (NF-κB), cyclooxygenase-2 (COX-2), 5-lipoxygenase (5-LOX), and NADPH oxidase-1 (NOX-1) and decreased the catalase level in sciatic nerve and brainstem. The observed neuro-inflammatory changes were accompanied with glial cells activation (increased GFAP and CD68 positive cells), apoptosis (increased Bax) and structural changes in both brainstem and sciatic nerve. The studied extract attenuated the CCI-induced neuro-inflammatory changes, oxidative stress, and apoptosis while it induced the expression of Bcl-2 and catalase in a dose dependent manner. It also decreased the brainstem expression of CD68 and GFAP indicating a possible neuroprotection effect. Taking together, P. perfoliatus may be considered as a novel therapy for neuropathic pain patients after performing the required clinical trials.

Abstract. Background: This prospective study was designed to evaluate the effect of inflammatory markers on the presence and progression of subclinical markers of carotid atherosclerosis in a 3.8-year follow-up period in patients with type 2 diabetes mellitus (T2DM). Patients and methods: A total of 595 subjects with T2DM were enrolled. Subclinical markers of carotid atherosclerosis (carotid intima media thickness (CIMT), plaque thickness, and plaques presence) were assessed with ultrasound at the time of recruitment and again after 3.8 years. Subjects with T2DM were divided into 2 groups according to the plasma high sensitive C-reactive protein (hs-CRP) levels (subjects with hs-CRP ≥ 2 mg/L and subjects with hs-CRP below 2 mg/L). Results: Subjects with T2DM and hs-CRP levels ≥ 2 mg/L had higher CIMT in comparison with subjects with T2DM and hs-CRP levels below 2 mg/L, and higher incidence of plaques/unstable plaques in comparison with subjects with T2DM and hs-CRP levels below 2 mg/L. Multivariate logistic regression analysis found the association between the HDL cholesterol level and presence of plaques, whereas the inflammatory marker hs-CRP was not associated with subclinical markers of progression of carotid atherosclerosis. Multiple linear regression analysis found the association between the hs-CRP levels and either CIMT progression rate or a change in the number of sites with plaques in a 3.8-year follow-up. Conclusions: We demonstrated an association between the inflammatory marker hs-CRP and either CIMT or incidence of plaques/unstable plaques at the time of recruitment in Caucasians with T2DM. Moreover, we found the association between hs-CRP levels and either CIMT progression rate or a change in the number of sites with plaques in a 3.8-year follow-up in subjects with T2DM.

Oxidative stress (OS) is increased in chronic diseases, including cardiovascular (CV), but there are few data on its effects on the heart and vessels. The isoprostanes (IsoP) are bioactive compounds, with 8-iso-PGF25a being the most representative in vivo marker of OS. They correlate with the severity of heart failure (HF), but because data regarding OS levels in different types of HF are scarce, our study was aimed to evaluate it by assessing the urinary levels of 8-iso-PGF2aand its correlations with various biomarkers and parameters. Our prospective study included 53 consecutive patients with HF secondary to ischemic heart disease or dilative cardiomyopathy, divided according to the type of HF (acute, chronic decompensated or chronic compensated HF). The control group included 13 hypertensive patients, effectively treated. They underwent clinical, laboratory - serum NT-proBNP, creatinine, uric acid, lipids, C reactive protein (CRP) and urinary 8-iso-PGF2a and echocardiographic assessment. HF patients, regardless the type of HF, had higher 8-iso-PGF2a than controls (267.32pg/�mol vs. 19.82pg/�mol, p[0.001). The IsoP level was directly correlated with ejection fraction (EF) (r=-0.31, p=0.01) and NT-proBNP level (r=0.29, p=0.019). The relative wall thickness (RWT) was negatively correlated with IsoP (r=-0.55, p[0.001). Also 8-iso-PGF25a was higher by 213.59pg/�mol in the eccentric left ventricular (LV) hypertrophy subgroup comparing with the concentric subgroup (p=0.014), and the subgroups with severe mitral regurgitation (MR) and moderate/severe pulmonary hypertension (PAH) had the highest 8-iso-PGF2a levels. Male sex, severe MR, moderate/severe PAH, high LV mass and low RWT values were predictive for high OS level in HF patients.Eccentric cardiac remodeling, MR severity and PAH severity are independent predictors of OS in HF patients.

Information concerning the mechanisms underlying oxidative stress and low-grade inflammation in young healthy women predisposing eventually to future diseases is scarce. We investigated the relationship of oxidative stress and high-sensitivity C-reactive protein (hsCRP) in fertile-age women by oral combined contraceptive (OC) use. Caucasian Italian healthy non-obese women (n = 290; 100 OC-users; 190 non-OC-users; mean age 23.2 ± 4.7 years) were analyzed. Blood hydroperoxides, as oxidative stress biomarkers, were assessed by Free Oxygen Radical Test (FORT). Serum hsCRP was determined by an ultra-sensitive method (hsCRP). Markedly elevated oxidative stress (≥400 FORT Units) was found in 77.0% of OC-users and 1.6% of non-OC-users, odds ratio (OR) = 209, 95% CI = 60.9–715.4, p < 0.001. Elevated hsCRP levels ≥ 2.0 mg/L, considered risky for cardiovascular diseases (CVDs), were found in 41.0% of OC-users and 9.5% of non-OC-users, OR = 6.6, 95%CI 3.5–12.4, p < 0.001. Hydroperoxides were strongly positively correlated to hsCRP in all women (rs = 0.622, p < 0.001), in OC-users (rs = 0.442, p < 0.001), and in non-OC-users (rs = 0.426, p < 0.001). Women with hydroperoxides ≥ 400 FORT Units were eight times as likely to have hsCRP ≥ 2 mg/L. In non-OC-users only, hydroperoxides values were positively correlated with weight and body mass index, but negatively correlated with red meat, fish and chocolate consumption. Our research is the first finding a strong positive correlation of serum hydroperoxides with hsCRP, a marker of low-grade chronic inflammation, in young healthy women. Further research is needed to elucidate the potential role of these two biomarkers in OC-use associated side-effects, like thromboembolism and other CVDs.

Objective: Synovitis, acne, pustulosis, hyperostosis, and osteitis (SAPHO) syndrome is a rare chronic inflammatory disorder and the underlying pathogenesis is unclear. In this study, 88 SAPHO patients and 118 healthy controls were recruited to investigate the role of serum-derived extracellular vesicles (SEVs) in SAPHO syndrome. Methods: Quantitative proteomics was applied for SEVs proteome identification, and ELISA and Western blotting was performed to verify the results of mass spectrum data. In vitro osteoclastogenesis and osteogenesis assay was used to confirm the effects of SEVs on bone metabolism. Results: Tandem mass tagging-based quantitative proteomic analysis of SAPHO SEVs revealed differential expressed proteins involved in bone metabolism. Of these, serum amyloid A-1 (SAA1) and C-reactive protein (CRP) were upregulated. Higher SAA1 levels in SAPHO patients were confirmed by ELISA. In addition, SAA1 levels were positively correlated with CRP, an inflammatory marker related to the condition of patients. In vitro celluler studies confirmed that SAPHO SEVs inhibited osteoclastogenesis in patients mainly in the active phase of the disease. Further analysis demonstrated that Nucleolin was upregulated in osteoclasts of active-phase patients under SAPHO SEVs stimulation. Conclusion: In this study, we identified SAA1 as an additional inflammation marker that can potentially assist the diagnosis of SAPHO syndrome, and speculated that Nucleolin is a key regulator of osteoclastogenesis in active-phase patients.

Background/Aims: This study aimed to discern whether the cardiac alterations caused by retinoic acid (RA) in normal adult rats are physiologic or pathologic. Methods and Results: Wistar rats were assigned into four groups: control animals (C, n = 20) received a standard rat chow; animals fed a diet supplemented with 0.3 mg/kg/day all-trans-RA (AR1, n = 20); animals fed a diet supplemented with 5 mg/kg/day all-trans-RA (AR2, n = 20); and animals fed a diet supplemented with 10 mg/kg/day all-trans-RA (AR3, n = 20). After 2 months, the animals were submitted to echocardiogram, isolated heart study, histology, energy metabolism status, oxidative stress condition, and the signaling pathway involved in the cardiac remodeling induced by RA. RA increased myocyte cross-sectional area in a dose-dependent manner. The treatment did not change the morphological and functional variables, assessed by echocardiogram and isolated heart study. In contrast, RA changed catalases, superoxide dismutase, and glutathione peroxidases and was associated with increased values of lipid hydroperoxide, suggesting oxidative stress. RA also reduced citrate synthase, enzymatic mitochondrial complex II, ATP synthase, and enzymes of fatty acid metabolism and was associated with increased enzymes involved in glucose use. In addition, RA increased JNK 1/2 expression, without changes in TGF-β, PI3K, AKT, NFκB, S6K, and ERK. Conclusion: In normal rats, RA induces cardiac hypertrophy in a dose-dependent manner. The non-participation of the PI3K/Akt pathway, associated with the participation of the JNK pathway, oxidative stress, and changes in energy metabolism, suggests that cardiac remodeling induced by RA supplementation is deleterious.

We defined the acute phase behaviour of a number of rabbit plasma proteins in studies (in vivo) and studied the effects of monokine preparations on their synthesis by rabbit primary hepatocyte cultures. Following turpentine injection, increased serum levels of C-reactive protein, serum amyloid A protein, haptoglobin, ceruloplasmin, and decreased concentrations of albumin were observed. In contrast to what is observed in man, concentrations of alpha 2-macroglobulin and transferrin were increased. Co-culture of primary hepatocyte cultures with lipopolysaccharide-activated human peripheral blood monocytes or incubation with conditioned medium prepared from lipopolysaccharide-activated human or rabbit monocytes resulted in dose-dependent induction of serum amyloid A, haptoglobin, ceruloplasmin and transferrin and depression of albumin synthesis, while C-reactive protein synthesis and mRNA levels remained unchanged. A variety of interleukin-1 preparations induced dose-dependent increases in the synthesis and secretion of serum amyloid A, haptoglobin, ceruloplasmin and transferrin and decreased albumin synthesis. Human recombinant tumour necrosis factor (cachectin) induced a dose-dependent increase in synthesis of haptoglobin and ceruloplasmin. In general, human interleukin-1 was more potent than mouse interleukin-1 and tumour necrosis factor. None of the monokines we studied had an effect on C-reactive protein synthesis or mRNA levels. These data confirm that C-reactive protein, serum amyloid A, haptoglobin and ceruloplasmin display acute phase behaviour in the rabbit, and demonstrate that, in contrast to their behaviour in man, alpha 2M and transferrin are positive acute phase proteins in this species. While both interleukin-1 and tumour necrosis factor regulate biosynthesis of a number of these acute phase proteins in rabbit primary hepatocyte cultures, neither of these monokines induced C-reactive protein synthesis. Comparison of these findings with those in human hepatoma cell lines, in which interleukin-1 does not induce serum amyloid A synthesis, suggests that the effect of interleukin-1 on serum amyloid A synthesis may be indirect.
