Abstract
BACKGROUND Diabetes mellitus (DM) is a non-communicable, life-threatening syndrome that is present all over the world. The use of eco-friendly, cost-effective, and green-synthesised nanoparticles as a medicinal therapy in the treatment of DM is an attractive option. OBJECTIVE In the present study, silver nanoparticles (AI-AgNPs) were biosynthesized through the green synthesis method using Azadirachta indica seed extract to evaluate their anti-diabetic potentials. METHODS These nanoparticles were characterized by using UV-visible spectroscopy, Fourier transform infrared spectrophotometers (FTIR), scanning electron microscopy (SEM), DLS, and X-ray diffraction (XRD). The biosynthesized AI-AgNPs and crude extracts of Azadirachta indica seeds were evaluated for anti-diabetic potentials using glucose adsorption assays, glucose uptake by yeast cells assays, and alpha-amylase inhibitory assays. RESULTS Al-AgNPs showed the highest activity (75 ± 1.528%), while crude extract showed (63 ± 2.5%) glucose uptake by yeast at 80 µg/mL. In the glucose adsorption assay, the highest activity of Al-AgNPs was 10.65 ± 1.58%, while crude extract showed 8.32 ± 0.258% at 30 mM, whereas in the alpha-amylase assay, Al-AgNPs exhibited the maximum activity of 73.85 ± 1.114% and crude extract 65.85 ± 2.101% at 100 µg/mL. The assay results of AI-AgNPs and crude showed substantial dose-dependent activities. Further, anti-diabetic potentials were also investigated in streptozotocin-induced diabetic mice. Mice were administered with AI-AgNPs (10 to 40 mg/kg b.w) for 30 days. CONCLUSIONS The results showed a considerable drop in blood sugar levels, including pancreatic and liver cell regeneration, demonstrating that AI-AgNPs have strong anti-diabetic potential.

Abstract
Azadirachta indica has previously been demonstrated to act as a multi‑functional medicinal plant for >2,000 years in India, and its neighboring countries. Currently, it is considered a natural resource with great value used in industrial product development and as a medicine for various types of diseases. The present study investigated the neuroprotective effects of Azadirachta indica which improved functional recovery in the 6‑hydroxydopamine induced rat Parkinson's disease (PD) model. Catalase, glutathione‑peroxidase, tumor necrosis factor‑α, interleukin (IL)‑1β, IL‑6, nuclear factor (NF)‑κB p65, inducible nitric oxide synthase (iNOS) and AChE activity levels were analyzed via ELISA. Western blotting was used to analyze B cell lymphoma‑2 associated X protein (Bax), cytochrome c and p53 protein expression. Treatment with Azadirachta indica significantly decreased the PD‑induced rotational behavior in rats. PD‑induced catalase, glutathione‑peroxidase, iNOS activity and iNOS protein expression were significantly suppressed by treatment with Azadirachta indica. Inflammatory factors, acetylcholinesterase activity and cyclo‑oxygenase‑2 protein expression levels were additionally significantly suppressed by treatment with Azadirachta indica. The protein expression levels of Bax, cytochrome c and p53 were decreased and caspase‑3 and caspase‑9 activities diminished, with treatment with Azadirachta indica. Therefore, Azadirachta indica was demonstrated to exhibit neuroprotective antioxidative and anti‑apoptotic effects in Parkinson's disease.

Abstract
The aim of this study was to evaluate the effect of isoflurane + N2O inhalation and propofol + fentanyl anesthesia on myocardial function as assessed by cardiac troponin T (cTnT). A total of 60 patients were randomized into two groups: isoflurane + N2O inhalation (n=30) and propofol + fentanyl anesthesia (n=30). The findings demonstrated that there was no significant difference between the two experimental groups in terms of cTnT levels, demographic properties or hemodynamic parameters. Isoflurane + N2O inhalation and propofol + fentanyl anesthesia, respectively, were also investigated in a rat model of myocardial infarction. Myocardial cell damage, inflammation and oxidative stress levels, caspase-3/9 activities and cyclooxygenase-2 protein expression were markedly decreased, although there was no statistical significance difference between the two experimental groups. Notably, inducible nitric oxide synthase protein expression in the isoflurane + N2O inhalation group was significantly higher than that of the propofol + fentanyl anesthesia group (P<0.01). In conclusion, isoflurane + N2O inhalation and propofol + fentanyl anesthesia are not associated with risks for myocardial function.

Abstract
Neem (Azadirachta indica A. Juss.) leaf has been reported to exert anti-inflammatory, antibacterial and antioxidant effects. The purpose of this study was to investigate the protective effects of neem leaf extract (NLE) against cigarette smoke (CS)- and lipopolysaccharide (LPS)-induced pulmonary inflammation. Treatment with NLE significantly attenuated the infiltration of inflammatory cells, such as neutrophils and macrophages in bronchoalveolar lavage fluid (BALF). NLE also reduced the production of reactive oxygen species and the activity of neutrophil elastase in BALF. Moreover, NLE attenuated the release of pro-inflammatory cytokines, such as tumor necrosis factor-α (TNF-α) and interleukin (IL)-6 in BALF. NLE inhibited the recruitment of inflammatory cells and the expression of monocyte chemoattractant protein-1 (MCP-1) in the lungs of mice with CS- and LPS-induced pulmonary inflammation. NLE also decreased the expression of inducible nitric oxide synthase (iNOS) in the lungs of the mice CS- and LPS-induced pulmonary inflammation. Furthermore, treatment with NLE significantly attenuated the activation of extracellular signal-regulated kinase (ERK) and c-Jun N-terminal kinase (JNK) in the lungs mice exposed to CS and LPS. NLE also inhibited the phosphorylation of nuclear factor (NF)-κB and inhibitor of NF-κB (IκB) in the lungs of mice expose to CS and LPS. These findings thus suggest that NLE has potential for use in the treatment of chronic obstructive pulmonary disease.

Zhang K, Jiao XF, Li JX, Wang XW. Rhein inhibits lipopolysaccharide-induced intestinal injury during sepsis by blocking the toll-like receptor 4 nuclear factor-κB pathway. Mol Med Rep 2015; 12:4415-4421. [PMID: 26081522 DOI: 10.3892/mmr.2015.3925] [Citation(s) in RCA: 32] [Impact Index Per Article: 3.6] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/19/2014] [Accepted: 04/30/2015] [Indexed: 11/05/2022] Open
Abstract
Sepsis is one of the leading causes of mortality in severe systemic inflammatory syndrome. The endotoxin-induced inflammatory response has been linked to the development of sepsis. Rhein is a lipophilic anthraquinone isolated from Rheum rhabarbarum (rhubarb), which has a protective effect on intestinal damage in vivo. However, the underlying mechanism responsible for the protective effects of rhein remains to be elucidated. In the present study, mice were exposed to 20 mg/kg lipopolysaccharide (LPS), prior to being treated with either 100 mg/kg rhein or 0.3 mg/kg toll‑like receptor 4 (TLR4) signaling inhibitor TAK‑242. In the rhein‑treated mice, the colon length (cm) was extended and colon injury was attenuated. In addition, treatment with rhein significantly decreased the expression levels of the LPS‑induced inflammatory cytokines interleukin (IL)‑1β, IL‑6, IL‑8, and tumor necrosis factor‑α, in both the plasma and colon tissue. However, mice treated with TAK‑242 exhibited increased expression levels of IL‑10, as determined by ELISA and western blot analysis. In addition, immunohistochemistry and western blot analyses demonstrated that treatment with rhein was able to reduce TLR4 expression and inhibit nuclear factor‑κB (NF‑κB) phosphorylation in colon tissue. Furthermore, LPS induction was blocked by TAK‑242. These results demonstrate that the observed rhein‑attenuated inflammatory response during sepsis may be achieved via the TLR4 NF‑κB signaling pathway. In conclusion, the results of the present study provide a novel insight into the protective effects of rhein on LPS‑induced intestinal inflammation, and demonstrate that rhein may act as a beneficial therapeutic agent in the treatment of sepsis-induced intestinal damage.
