Background: Coenzyme Q10 is a well-known cofactor in the mitochondrial electron transport chain required for ATP production. Coenzyme Q10 is recognized as an intracellular antioxidant that protects cell membrane phospholipids, mitochondrial membrane protein, and plasma low-density lipoprotein against oxidative damage caused by free radicals. Diabetes and its complications have been related to increased levels of free radicals and systemic proinflammatory cytokines and to an abnormal lipid profile. The aim of this study was to investigate the effects of coenzyme Q10 supplementation on some cytokine levels in streptozotocin-induced diabetic rats.Materials, Methods & Results: In this study, 38 healthy, adult male rats were used. The rats were divided into 5 groups. All animals were housed in separated cages during the four weeks. The animals in group 1 was fed standard rat pellets for 4 weeks. It was administered at 0.3 mL corn oil intraperitoneally daily for four weeks in group 2 animals. The animals in group 3 was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. Group 4 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and group 5 was made diabetic by subcutaneous injections of streptozotocin at dose of 40 mg/kg in 0.1 M citrate buffer (pH 4.5) single daily dose for two days and then was injected intraperitoneally with 10 mg/kg CoQ10 daily for 4 weeks. During the experiment, three animals from group 4 and one animals from group 5 were died due to streptozotocin-induced hypoglycemia. At the end of the study, blood samples were taken from all animals. In these blood samples, IL-4, IL-6, IL-10 and TNF-α plasma levels were determined with ELISA using sandwich enzyme-linked immunosorbent method via commercial kits. In this study, IL-4 level as an anti-inflammatory cytokine significantly decreased (P < 0.05) with diabetes induction compared to control group level. IL-10 level in diabetic group was statistically different (P < 0.05) from control group level. CoQ10 application to diabetic animals improved the falling in IL-10 level of diabetic group (P < 0.05). IL-6 and TNF-α levels in diabetic group significantly increased (P < 0.05) in parallel with each other compared to control group levels. The same parameters were reduced (P < 0.05) by CoQ10 application in diabetic animals.Discussion: In this study, the occurred changes in pro- and anti-inflammatory cytokines with experimentally induced diabetes are expected results and these results are consistent with some studies related diabetes. These results may be considered to hazardous effects and inflammation caused by diabetes on liver, pancreas and other tissues. CoQ10 suppressed the increments in plasma pro-inflammatory cytokine levels, whereas it restored the reducing in anti-inflammatory cytokine levels arising due to diabetes. The obtained results from this study after CoQ10 application supported similar studies used CoQ10 application against deleterious effects of diabetes in animals and humans. Therefore, it is possible to say that CoQ10 may play important role in regulation of imbalance between inflammation markers in diabetes conditions and further studies are needed to clear the beneficial effects of CoQ10 treatment on the other inflammation markers in diabetes status.

Abstract Objective: Enhanced recovery after surgery (ERAS) protocols are established in adults but not fully evaluated in children. This study investigated whether an ERAS protocol improved recovery and influenced postoperative inflammatory cytokine levels in children undergoing surgery for hydronephrosis. Methods: This randomized controlled study included patients who underwent robot-assisted laparoscopic surgery for hydronephrosis at Bayi Children's Hospital (Beijing, China) between October 2018 and September 2019. Patients were randomized to an ERAS group (perioperative ERAS protocol) or control group (standard perioperative management). Outcomes related to postoperative recovery and inflammatory cytokine levels were evaluated. Results: The final analysis included 18 patients in each group. Five patients (27.78%) in each group experienced postoperative complications (abdominal pain, nausea and vomiting, subcutaneous emphysema or fever). The ERAS group had a shorter time to first postoperative flatus than the control group (25 vs. 49 hours; P =0.009), although the time for abdominal drainage flow to reach ≤20 mL/day, time to urinary catheter removal and length of hospital stay did not differ significantly between groups. Preoperative plasma cytokine levels were comparable between groups. Compared with the control group, the ERAS group had a higher IL-6 level on postoperative day 2 ( P <0.05) and a lower concentration of IL-1β on postoperative days 1 and 2 ( P <0.05). Postoperative levels of CRP, TNFα and IL-10 did not differ significantly between groups. Conclusions: ERAS may accelerate postoperative recovery and modulate the postoperative inflammatory response in pediatric patients undergoing robot-assisted laparoscopic pyeloplasty for hydronephrosis.

Background: We investigated whether the frequency of lower urinary tract symptoms (LUTS) increased in patients in whom double-J stents were applied. We also evaluated several medical therapy protocols to treat symptoms related with ureteral stents.Materials and Methods: A total of 108 patients, in whom unilateral double-j stent was applied during ureteral stone treatment, were included. Before the double-J stent was applied, all patients completed storage components of the “International Prostate Symptom Score” (IPSSs), quality of life components of the IPSS (IPSS-QOL) and “Overactive Bladder Questionnaire” (OABq) forms and scores were calculated. After the procedure, cases were randomized into 5 groups, an antiinflammatory was given to Group 1, spasmolytic to Group 2, anticholinergic to Group 3 and α-blocker to Group 4. No additional drug was given to Group 5 as this control group. During the fourth week of the procedure, IPSSs, IPSS-QOL and OABq forms were again completed and scores were compared with the previous ones.Results: When all the cases were evaluated, the IPSSs, IPSS-QOLand OABq scores of patients in whom the double-J stent was applied were statistically significantly higher the procedure. Compared to the control group, the cases where the double-J stent was applied showed a higher IPSSs, IPSS-QOL and OABq scores and none of the medical therapies could prevent this increase.Interpretation: The frequency of LUTS increased in cases where the ureteral stent was applied and discomfort continued as long as the stent stayed in the body.

The advantage in response of Th2 over Th1 is observed in normal pregnancy in peripheral blood. A disturbance of this balance can lead to symptoms of miscarriage and pregnancy loss. The aim of this study was to evaluate the pro- and anti-inflammatory cytokines in sera of women who were diagnosed with missed miscarriage in the first trimester and to compare this systemic immune response to the response in women with normal pregnancy. The study group consisted of 61 patients diagnosed with missed miscarriage. In total, 19 healthy women with uncomplicated first trimester created the control group. Cytokines were determined in the maternal serum by ELISA. The analysis included INF-γ, TNF-α, Il-1β, Il-4, Il-5, Il-6, Il-9, Il-10, Il-13 and TGF-β1. Th1 cytokine levels in the study group reached slightly higher values for INF-γ, Il-1β and slightly lower for IL-6 and TNF-α. In turn, Th2 cytokine levels in the study group were slightly higher (Il-9, Il-13), significantly higher (Il4, p = 0.015; Il-5, p = 0.0003) or showed no differences with the control group (Il-10). Slightly lower concentration involved only TGF-β1. Analysis of the correlation between levels of pro- and anti-inflammatory cytokines resulted in some discrepancies, without showing predominance of a specific immune response. The results did not confirm that women with missed miscarriage had an advantage in any type of immune response in comparison to women with normal pregnancy.

In medical sciences, toxicity is an area wherein extensive studies have been carried to improve the diseases as well as to prevent. So, there is a high requirement for novel and improved alternative therapeutic strategies to manage diseases. The liver is the largest gland in the body, which executes several important mechanisms; it stores minerals and vitamins and releases them in periods of need. The main aim of this study was to give a closer insight into potent non- toxic compounds that is capable of modifying the responses. Animals were divided into five equal groups viz control (Group 1), administered with food and water ad libitum, (Group 2) administered with olive oil, (Group 3) administered with zingerone, (Group 4) administered with concanavalin A, (Group 5) administered with cyclosporine A followed by zingerone. Our results revealed significant changes in liver marker enzymes and liver histology of zingerone treated rats when compared to control rats.  A corollary, zingerone has no toxic effect on hepatocytes and was found to be safe at a dose of 10mg/kg b wt and also ameliorates hepatotoxicity.

The aim of the present study was to evaluate the efficacy of interfacial bonding between resin cement and titanium alloy conditioned with different Photobiomodulataion Therapy (PBT) in comparison with conventional regimes. Seventy-five samples of titanium bar were segmented polished; and based on conditioning regime divided into five groups (15 each specimens). Group 1: No treatment (control), Group 2: Sand blasting with 120 µm Al2O3, Group 3: Er,Cr:YSGG (ECL), Group 4: Er:YAG laser (EYL), Group 5: Nd:YAG laser (NYL). After different conditioning regimes, resin cement was mixed and applied. All specimens were thermocycled for 500 cycles and positioned on universal testing machine for shear bond strength testing. Modes of failure was assessed by a single examiner using stereomicroscope at 40× magnification. Three pairs of specimens in each group were sputter coated and scanning electron microscope (SEM) images were taken at 1000× magnification using 20 Kv. The highest SBS values were observed in group 2 (14.25±2.29 MPa) and the lowest bond values were displayed in group 1 (6.98 ±0.59 MPa). Titanium alloy abutments conditioned with different laser prototypes ECL (11.22±1.40 MPa), EYL (9.29±1.22 MPa) and NYL (9.12 ±1.84 MPa) exhibited comparable SBS (p > 0.05). Adhesive failures were primarily dominant among all experimental groups. Photo-biomodulation in the form of ECL lasers has the potential to be used as a supplement to sandblasting procedure in conditioning of cement retained titanium alloy implant abutments.

The reproductive performance of sows is influenced by numerous factors, including environment. The time of ovulation in response to hormonal treatment might vary depending on climate. Because control of ovulation in pigs using hormonal treatments has not been studied in the tropical climate, the effect of hCG or GnRH analog (buserelin) on the time of ovulation in weaned sows was investigated. Thirty-three multiparous Landrace (L; n = 14) and Yorkshire (Y; n = 19) sows housed in the mating and gestation unit on a commercial swine farm in Thailand were used. The average of maximum and minimum daily temperature and daily humidity during experiment was 35°C and 25°C and 31%, respectively. Estrus detection by back pressure test and presence of a mature boar was performed every 6 h. Only sows with weaning to estrus interval (WOI) of ≤7 days were studied. Estrous sows were randomly allocated to 3 groups: a control group (4 Y and 6 L), which was given no treatment; a group (5 Y and 5 L) given 750 IU of hCG i.m. at the beginning of estrus (hCG group); and a group (5 Y and 8 L) given 10 μg of GnRH analog i.m. at the beginning of estrus (GnRH group). The mean time of ovulation was monitored by transrectal ultrasonography every 6 h from the onset of estrus. Interval from onset of estrus to mean time of ovulation (EOI) was analyzed using general linear model procedures of SAS (version 9.0; SAS Institute, Cary, NC, USA). Least squares means and standard deviations of EOI were compared using ANOVA. The proportion of sows ovulating within 45 h after onset of estrus was compared using Fisher’s exact test. Differences with P < 0.05 were considered significant. All of the sows in the control and hCG groups ovulated within 5 days after onset of estrus, but 3 out of 13 (23%) sows in the GnRH group developed cystic follicles; these 3 sows were excluded from the analyses. Overall, WOI was 3.8 ± 0.9 days and did not differ among the groups (P ± 0.05). The breed of sow had no effect on the EOI (P ± 0.05). Although the EOI did not differ among the control (43.0 ± 19.2 h), hCG (40.2 ± 5.5 h), and GnRH (37.5 ± 10.3 h) groups (P ± 0.05), variation was less (P = 0.001) after administration of hCG or GnRH. In addition, the proportions of sows that ovulated within 45 h after onset of estrus in the hCG (9/10 sows) and GnRH (8/10 sows) groups tended to be higher than in the control group (5/10 sows; P = 0.10). In conclusion, results indicate that both hCG and GnRH are efficacious in inducing ovulation at a predictable time in weaned, spontaneously estrous sows. The occurrence of follicular cysts in GnRH-treated sows requires further investigation.

Abstract Background Neuroinflammation plays a major role in the pathogenesis of autism because the cytokine levels are typically disturbed in the brain in autistic patients. Prebiotics-rich diet maintains the healthy gut microbiota and hence can regulate the neuroinflammation indirectly. The study aimed to investigate the role of bee pollen and propolis in ameliorating neuroinflammation, including cytokine levels, in an animal model of autism. Methods Hamsters were classified as four groups: Group I, control; Group II, autistic model/animals treated with 250 mg propionic acid (PPA)/kg body weight (BW)/day for 3 days; Group III, animals treated with bee pollen at a dose of 250 mg/kg BW/day for 4 weeks; and Group IV, animals treated with propolis at a dose of 250 mg/kg BW/day for 4 weeks. Neuroinflammatory responses were evaluated using the levels of interferon γ (IFN-γ), interleukin 1 alpha (IL-1α), IL-6, IL-10, IL-12 (p70), vascular endothelial growth factor (VEGF), and tumor necrosis factor α (TNFα). Results Significant decrease of IL-10 (P<0.026), VEGF (P<0.005), and TNFα(P<0.005) levels and increased IL-1α (P<0.032), IL-6(P<0.028), and IFN-γ (P<0.013) levels were observed between the four studied groups. The neurotoxic effects of PPA was clearly presented as much higher IL-6, as pro-inflammatory cytokine (P<0.05), concomitant with much lower IL-10, as anti-inflammatory cytokine(P<0.015) compared to controls. Both bee pollen and propolis were effective in ameliorating the neurotoxic effects of PPA demonstrating non-significant changes of IL-6 and IL-10 when compared to control healthy hamsters. Conclusions Our findings indicate that both bee pollen and propolis protect against neuroinflammation in the rodent model of autism. However, further studies are needed to investigate the clinical benefits of prebiotics-rich diet in neurodevelopmental disorders, such as autism.
