This study was performed to evaluate the effect of liraglutide on experimental testicular ischaemia reperfusion in rats in terms of biochemistry, histopathology and immunohistochemistry. A total of 28 male Wistar-Albino rats were divided randomly into 4 groups: control (7), sham (7), ischaemia-reperfusion (7) and ischaemia-reperfusion + liraglutide (7). Biochemically, Nitric Oxide, Malondialdehyde, Superoxide dismutase, Glutathione peroxidase and Catalase levels were measured in the testis. Apoptosis protease activating factor-1 and inducible nitric oxide synthase activity were evaluated immunohistochemically as well. Statistical analyses were made via the Kruskal–Wallis and Mann–Whitney U tests. In the reperfusion group, CAT and SOD values were increased (p > .05), NO and MDA values were decreased (p < .05) after administration of liraglutide. In addition, GPx values were significantly increased in ischaemia reperfusion + liraglutide administered group compared to reperfusion group (p < .05). Apaf-1 and iNOS activity were significantly decreased with the addition of liraglutide treatment to the ischaemia-reperfusion group (p < .05). First of all, we would like to say that liraglutide treatment is moderately preventive against I/R injury in testicular torsion. The anti-inflammatory, antioxidant and antiapoptotic properties of liraglutide are create a moderately protective effect as we show in this study. 相似文献

Objective:
IDegLira is a novel, fixed-ratio combination of the long-acting basal insulin, insulin degludec, and the long-acting glucagon-like peptide-1 analog liraglutide. We studied the effect of IDegLira versus its components on postprandial glucose (PPG) in type 2 diabetes.Methods:
In this substudy, 260 (15.6%) of the original 1663 patients with inadequate glycemic control participating in a 26-week, open-label trial (DUAL I) were randomized 2:1:1 to once-daily IDegLira, insulin degludec or liraglutide. Continuous glucose monitoring (CGM) for 72 hours and a meal test were performed.Results:
At week 26, IDegLira produced a significantly greater decrease from baseline in mean PPG increment (normalized iAUC0-4h) than insulin degludec (estimated treatment difference [ETD] −12.79 mg/dl [95% CI: −21.08; −4.68], P = .0023) and a similar magnitude of decrease as liraglutide (ETD −1.62 mg/dl [95% CI: −10.09; 6.67], P = .70). CGM indicated a greater reduction in change from baseline in PPG increment (iAUC0-4h) for IDegLira versus insulin degludec over all 3 main meals (ETD −6.13 mg/dl [95% CI: −10.27, −1.98], P = .0047) and similar reductions versus liraglutide (ETD −1.80 mg/dl [95% CI: −2.52, 5.95], P = .4122). Insulin secretion ratio and static index were greater for IDegLira versus insulin degludec (P = .048 and P = .006, respectively) and similar to liraglutide (P = .45 and P = .895, respectively).Conclusions:
Once-daily IDegLira provides significantly better PPG control following a mixed meal test than insulin degludec. The improvement is at least partially explained by higher endogenous insulin secretion and improved beta cell function with IDegLira. The benefits of liraglutide on PPG control are maintained across all main meals in the combination. 相似文献304.

Background and Aim
A glucagon‐like peptide‐1 analog, liraglutide, has been reported to block inflammatory somatic pain. We hypothesized that liraglutide attenuates lipopolysaccharide (LPS)‐induced and repeated water avoidance stress (WAS)‐induced visceral hypersensitivity and tested the hypothesis in rats.Methods
The threshold of the visceromotor response induced by colonic balloon distention was measured to assess visceral sensation. Colonic permeability was determined in vivo by quantifying the absorbed Evans blue spectrophotometrically, which was instilled in the proximal colon for 15 min. The interleukin‐6 level in colonic mucosa was also quantified using ELISA.Results
Subcutaneously injected LPS (1 mg/kg) reduced the visceromotor response threshold after 3 h. Liraglutide (300 μg/kg subcutaneously) at 15 h and 30 min before injecting LPS eliminated LPS‐induced allodynia. It also blocked the allodynia induced by repeated water avoidance stress for 1 h for three consecutive days. Neither vagotomy nor naloxone altered the antinociceptive effect of liraglutide, but NG‐nitro‐L‐arginine methyl ester, a nitric oxide synthesis inhibitor, blocked it. LPS increased colonic permeability and the interleukin‐6 level, and the analog significantly inhibited these responses.Conclusions
This study suggests that liraglutide blocked LPS‐induced visceral allodynia, which may be a nitric oxide‐dependent response, and was probably mediated by inhibiting pro‐inflammatory cytokine production and attenuating the increased gut permeability. Because the LPS‐cytokine system is considered to contribute to altered visceral sensation in irritable bowel syndrome, these results indicate the possibility that liraglutide can be useful for treating this disease. 相似文献305.

Background
Neurogenesis including neurite outgrowth is important for brain plasticity under physiological conditions and in brain repair after injury. Liraglutide has been found to have neuroprotective action in the risk of central nervous system disease. However, the effect and the potential mechanism of liraglutide-induced neurite outgrowth in primary cortical neurons under oxidative stress remain poorly documented.Methods
In the text, H2O2 was used to mimic ischemia injury in primary cortical neurons. The viability and apoptosis of cell was assessed by Cell Counting Kit-8 and Hoechst 33342. Immunofluorescence method was used to examine the effect of liraglutide on neurite outgrowth in cortical neuron under H2O2 condition. Then, the potential mechanisms involving the Wnt pathway were investigated. The expression of β-catenin, c-myc, and cyclin D1 was determined using quantitative real-time polymerase chain reaction and Western blot.Results
Liraglutide significantly increased the viability and alleviated the apoptosis rate of cortical neurons induced by H2O2. Next, liraglutide promoted neurite outgrowth, which could be partially inhibited by the Wnt pathway inhibitor Xav939. Besides, liraglutide induced an increase of β-catenin, c-myc, and cyclin D1 levels, which could also be blocked in the presence of Xav939.Conclusions
These results illustrate that liraglutide exerts neurotrophin-like activity in cortical neurons under oxidative stress condition, partly through activating the Wnt pathway. 相似文献306.

Tirzepatide is a new glucagon-like peptide-1 receptor agonist (GLP-1RA) that has shown promising results for weight loss. A Bayesian network meta-analysis was conducted to compare the efficacy and safety of GLP-1RAs for obesity management. Embase and MEDLINE were searched looking for randomized clinical trials (RCTs) that evaluated the efficacy of GLP-1RAs for weight loss in patients without diabetes. The main efficacy outcomes evaluated were the mean change in actual and percentage weight loss and the proportion of patients with weight loss of ≥5%–20%. Main safety outcomes evaluated include nausea, vomiting, diarrhea, constipation, loss of appetite, pancreatitis, gallbladder-related disorders, and withdrawal due to adverse events. Seven RCTs with more than 12,300 patients were analyzed, including patients with body mass index (BMI) ≥ 30 kg/m2, or BMI ≥ 27 kg/m2 with comorbidities. Weekly tirzepatide 10 and 15 mg resulted in more weight loss than weekly semaglutide 2.4 mg, daily semaglutide 0.4 mg, or liraglutide 3 mg. Tirzepatide and weekly semaglutide demonstrated comparable results but with significantly higher odds of achieving ≥5%–20% weight loss compared with liraglutide. GLP-1RAs triggered more gastrointestinal adverse events than placebo, with no in-between difference. Although all GLP-1RAs lead to significant weight reduction, tirzepatide was associated with better efficacy outcomes while having a comparable safety profile. 相似文献
