Abstract Introduction Benign prostatic hyperplasia (BPH) is a major urologic problem that mostly develops in older males. Oxidative stress and inflammation influence the occurrence of BPH. Berberine (BBR) is a natural ingredient that has antioxidant and anti-inflammatory properties. The current research aims at examining the effects of BBR on testosterone-stimulated BPH in rats. Methods Animals were randomly categorized to six groups. In the control group, normal saline and olive oil were injected as the vehicle. BPH group: received testosterone (3 mg/kg, subcutaneous, 28 days), BPH + BBR groups; received BBR (25 and 50 mg/kg, p.o, 28 days), BPH + finasteride groups: received finasteride (1 mg/kg, p.o, 28 days), BBR (50 mg/kg, p.o, alone) was administered for subjects in the BBR group. On the 29th day, after anesthesia, cervical dislocation was used to kill the subjects. Serum concentration of testosterone and dihydrotestosterone was measured and prostate tissues were excised and used for biochemical, inflammation, and histological analysis. Results BBR prevented increased serum concentrations of testosterone and dihydrotestosterone. BBR considerably reduced BPH-stimulated oxidative stress and inflammation through preventing the rise in lipid peroxidation and nitrite concentration and declined the accumulations of pro-inflammatory cytokines (e.g. interleukin 1β and tumor necrosis factor α) and declining the depletion rate of GSH and the function of catalase and superoxide dismutase. Histopathological investigations reported that administration of BBR could suppress testosterone-stimulated BPH. Conclusion This study demonstrated that BBR could significantly prevent the development of BPH in rats.

Abstract Background: Beta-thalassaemia (β-thalassaemia) major patients are severely anaemic and require life-long blood transfusions for survival. These patients require iron-chelation therapy as a result of iron overload due to the monthly blood transfusions. The iron over load can cause oxidative damage and pro-inflammation and therefore, hasten mortality. Thus, regular monitoring of the oxidative stress and pro-inflammation status may be useful in these patients. Methods: Measurement of biomarkers is usually performed on serum samples but the evaluation in non-invasive samples such as saliva would be more favourable in paediatric cases. In this study, the levels of pro-inflammatory cytokines such as tumour necrosis factor-α (TNF-α) and interleukin-6 (IL-6) as well as oxidative indices such as lipid hydro peroxide, advanced oxidation protein products (AOPP), ferric reducing antioxidant power (FRAP), uric acid (UA) and glutathione peroxidase (GPx) activity in a total of 65 β-thalassaemia major patients (all on iron chelation) and 55 healthy control subjects were assessed. All the above biochemical parameters, measured using well established assay techniques, were detectable in saliva samples. Results: Non parametric analyses showed that lipid hydroperoxide (LH) and glutathione peroxidase (GPx) activities were significantly higher in β-thalassaemia major patients. All other parameters were not significantly different between patient and control groups implying that iron chelation therapy was successful in attenuating oxidative stress. Strong positive correlation was observed between FRAP and UA levels. There was also a notable difference in tumour necrosis factor-α (TNF-α) between the patients and healthy controls when analysed according to ethnicity and age. AOPP level in β+-thalassaemia homozygous patients were significantly higher than β+/β0-compound heterozygous and β0-thalassaemia homozygous patients. Conclusion: Saliva may serve as a reliable, non-invasive sample which can be used to assess oxidative indices and pro-inflammatory cytokines in β-thalassaemia major patients.

We aimed to investigate the effect of a 12-week Taekwondo self-defense training course on oxidative stress and inflammation in postmenopausal women. Sixteen middle-aged women participated and were randomized into two groups: a control group (CG, n = 8) and a Taekwondo self-defense training group (TSDG, n = 8). The TSDG was trained for 60 min, four times per week, for 12 weeks. Following the Taekwondo training intervention, side-step was significantly higher in the TSDG than in the CG (p < 0.001). Malondialdehyde levels were significantly lower after the intervention than before in the TSDG (p < 0.01). Superoxide dismutase (SOD) levels were also significantly higher after the intervention than before in the TSDG (p < 0.001). After the Taekwondo training intervention, SOD levels were significantly higher in the TSDG than in the CG (p < 0.01). Tumor necrosis factor α (TNF-α) levels were significantly lower after the intervention than before in the TSDG (p < 0.05). After the Taekwondo training intervention, TNF-α levels were significantly lower in the TSDG than in the CG (p < 0.05). The results of this study suggest that Taekwondo self-defense training is an effective exercise that improves agility, oxidative stress, and inflammatory responses in postmenopausal women.

Diabetic nephropathy is reported to occur as a result of the interactions between several pathophysiological disturbances, as well as renal oxidative stress and inflammation. We examined the effect of Malaysian propolis (MP), which has anti-hyperglycemic, antioxidant and anti-inflammatory properties, on diabetes-induced nephropathy. Diabetic rats were either treated with distilled water (diabetic control (DC) group), MP (300 mg/kg b.w./day), metformin (300 mg/kg b.w./day) or MP + metformin for four weeks. We found significant increases in serum creatinine, urea and uric acid levels, decreases in serum sodium and chloride levels, and increase in kidney lactate dehydrogenase activity in DC group. Furthermore, malondialdehyde level increased significantly, while kidney antioxidant enzymes activities, glutathione level and total antioxidant capacity decreased significantly in DC group. Similarly, kidney immunoexpression of nuclear factor kappa B, tumor necrosis factor-α, interleukin (IL)-1β and caspase-3 increased significantly, while IL-10 immunoexpression decreased significantly in DC group relative to normal control group. Histopathological observations for DC group corroborated the biochemical data. Intervention with MP, metformin or both significantly mitigated these effects and improved renal function, with the best outcome following the combined therapy. MP attenuates diabetic nephropathy and exhibits combined beneficial effect with metformin.

The application of gold nanoparticle-peptide conjugates as theranostic agents for colorectal cancer shows much promise. This study aimed at determining the neurotoxic impact of 14 nm gold nanoparticles (AuNPs) functionalized with colorectal cancer-targeting peptides (namely p.C, p.L or p.14) in a rat model. Brain tissue samples, obtained from Wistar rats that received a single injection of citrate-capped AuNPs, polyethylene glycol-coated (PEG) AuNPs, p.C-PEG-AuNPs, p.L-PEG-AuNPs or p.14-PEG-AuNPs, and sacrificed after 2- and 12-weeks, respectively, were analysed. Inflammation marker (tumour necrosis factor-α, interleukin-6, interleukin-1β), oxidative stress (superoxide dismutase, catalase, glutathione peroxidase) and apoptotic biomarker (cytochrome c, caspase-3) levels were measured. Gold nanoparticle-treated groups sacrificed after 2-weeks did not exhibit any significant inflammatory, oxidative stress or apoptotic effects in brain tissue compared to the untreated control group. In brain tissue from rats that were exposed to citrate-capped AuNPs for 12-weeks, tumour necrosis factor-α and interleukin-6 levels were significantly increased compared to the untreated control. Exposure to PEG-AuNP, p.C-PEG-AuNP, p.L-PEG-AuNP and p.14-PEG-AuNP did not elicit significant toxic effects compared to the control after 12-weeks, as evidenced by the absence of inflammatory, oxidative stress and apoptotic effects in brain tissue. We thus report on the safety of PEG-coated AuNP-peptide conjugates for potential application in the diagnosis of colorectal cancer; however, exposure to citrate-capped AuNPs could induce delayed neuro-inflammation, and as such, warrants further investigation.

Abstract Introduction: Trichomonas vaginalis infection is one of the most widespread sexually transmitted infections in the world. There are approximately 276 million cases worldwide. Most men remain undiagnosed and untreated because they are asymptomatic. The chronic inflammation induced by persistent infection may increase the risk of developing genitourinary cancers. In this study, we aimed to investigate the association between trichomoniasis and benign prostate hyperplasia (BPH), prostate cancer (PCa), and bladder cancer (BC) in Taiwan.Material and method: We designed a case-control study by using the database of the National Health Insurance program in Taiwan. We used the International Classification of Diseases, 9th Revision classifications to classify all the medical conditions in the case and control groups. All odds ratios (ORs) and 95% confidence intervals (CIs) were analyzed using multivariable logistic regression to adjust for all comorbidities and variables.Result: From 2000 to 2015, we enrolled a total of 62,544 individuals as the case group and 187,632 as the control group. Trichomoniasis exposure had a significant association with BPH and PCa (adjusted OR: BPH = 2.685, 95% CI = 1.233–4.286, P = 0.013; PCa = 5.801, 95% CI = 1.296–26.035, P = 0.016). The relative risk was much higher if patients had both trichomoniasis and depression (adjusted OR = 7.682, 95% CI = 5.730–9.451, P < 0.001).Conclusion: Men with trichomoniasis had a significantly higher risk of developing BPH and PCa than those without. Healthcare professionals should not only pay more attention to disease treatment, but also to public health education.

Andrographis paniculata was widely used in traditional herbal medicine to treat various diseases. This study explored the potential anti-aging activity of Andrographis paniculata in cutaneous cells. Human, adult, low calcium, high temperature (HaCaT) cells were treated with methanolic extract (ME), andrographolide (ANDRO), neoandrographolide (NEO), 14-deoxyandrographolide (14DAP) and 14-deoxy-11,12-didehydroandrographolide (14DAP11-12). Oxidative stress and inflammation were induced by hydrogen peroxide and lipopolysaccharide/TNF-α, respectively. Reactive oxygen species (ROS) production was measured by fluorescence using a 2′,7′-dichlorofluorescein diacetate (DCFH-DA) probe and cytokines were quantified by ELISA for interleukin-8 (IL-8) or reverse transcription-quantitative polymerase chain reaction (RT-qPCR) for tumor necrosis factor-α (TNF-α). Hyaluronic acid (HA) secretion was determined by an ELISA. Our results show a decrease in ROS production and TNF-α expression by ME (5 µg/mL) in HaCaT under pro-oxidant and pro-inflammatory conditions, respectively. ME protected HaCaT against oxidative stress and inflammation. Our findings confirm that ME can be used for the development of bioactive compounds against epidermal damage.

Purpose The sequelae of cancer treatment may increase systemic inflammation and create a phenotype at increased risk of functional decline and comorbidities, leading to premature mortality. Little is known about how this trajectory compares with natural aging among peers of the same age without cancer. This longitudinal study investigated proinflammatory cytokines and comorbidity development over time among breast cancer survivors and a noncancer control group. Methods Women (N = 315; 209 with breast cancer and 106 in the control group) were recruited at the time of their work-up for breast cancer; they completed the baseline questionnaire, interview, and blood draw (lipopolysaccharide-stimulated production of interleukin [IL] -6, tumor necrosis factor-α, and IL-1β). Measures were repeated 6 and 18 months after primary cancer treatment (cancer survivors) or within a comparable time frame (control group). Results There were no baseline differences in comorbidities or cytokines between survivors and the control group. Over time, breast cancer survivors had significantly higher tumor necrosis factor-α and IL-6 compared with the control group. Survivors treated with surgery, radiation, and chemotherapy accumulated a significantly greater burden of comorbid conditions and suffered greater pain associated with inflammation over time after cancer treatment than did the control group. Conclusion Survivors who had multimodal treatment had higher cytokines and comorbidities, suggestive of accelerated aging. Comorbidities were related to inflammation in this sample, which could increase the likelihood of premature mortality. Given that many comorbidities take years to develop, future research with extended follow-up beyond 18 months is necessary to examine the evidence of accelerated aging in cancer survivors and to determine the responsible mechanisms.

Abstract Lipopolysaccharide (LPS) acts as an endotoxin, releases inflammatory cytokines, and promotes an inflammatory response in various tissues. This study investigated whether LPS modulates neuroglia activation and nuclear factor kappa B (NF-κB)-mediated inflammatory factors in the cerebral cortex. Adult male mice were divided into control animals and LPS-treated animals. The mice received LPS (250 μg/kg) or vehicle via an intraperitoneal injection for 5 days. We confirmed a reduction of body weight in LPS-treated animals and observed severe histopathological changes in the cerebral cortex. Moreover, we elucidated increases of reactive oxygen species and oxidative stress levels in LPS-treated animals. LPS administration led to increases of ionized calcium-binding adaptor molecule-1 (Iba-1) and glial fibrillary acidic protein (GFAP) expression. Iba-1 and GFAP are well accepted as markers of activated microglia and astrocytes, respectively. Moreover, LPS exposure induced increases of NF-κB and pro-inflammatory factors, such as interleukin-1β (IL-1β) and tumor necrosis factor-α (TNF-α). Increases of these inflammatory mediators by LPS exposure indicate that LPS leads to inflammatory responses and tissue damage. These results demonstrated that LPS activates neuroglial cells and increases NF-κB-mediated inflammatory factors in the cerebral cortex. Thus, these findings suggest that LPS induces neurotoxicity by increasing oxidative stress and activating neuroglia and inflammatory factors in the cerebral cortex.

Sepsis, severe sepsis, and septic shock represent a serious medicinal and general social problem and still maintain an important position among the present issues in the basic and clinical research. In the prospective analysis of patients satisfying the criteria of septic condition, we determined serum levels of bioparameters in three consecutive days from the first signs of sepsis depending on the stage or advancement of the septic condition. We determined the most significant parameter/parameters which are able to determine the stage of sepsis or to predict patient's death. In the group of 68 patients, all monitored biomarkers showed significant difference in serum concentrations versus the control group (P = 0.001). The strongest positive connection between the seriousness of sepsis and serum level is in case of procalcitonin. Predictor of mortality (r = -0.468; P = 0.001), transferrin (r = -0.506; P = 0.003), and tumor necrosis factor-α (r = 0.939; P = 0.001). Our results show that the monitored parameters (procalcitonin, C-reactive protein, tumor necrosis factor-a, and interleukin 6) have strong correlations between the serum levels and the stage of disease. Examination of at least one cytokine in normal clinical practice might lead to better interpretation of the patient's condition, determining the risk of death.
