One of the encouraging processes to protect the environment is the catalytic conversion of N2O and other harmful greenhouse gases. Employing heteroatom dopants into the Graphene structure for this conversion is an attractive technique owing to its relatively low price and the very low destructive impacts. DFT was applied to explore fundamental and principal reactions of N2O adsorption and dissociation over the Silicon-embedded Graphene catalyst to contribute to the search for green catalysts in the conversion of toxic gases into less harmful ones. Forming a surface peroxy group O22-, N2O bond cleavage and oxygen atom transfer were theoretically investigated. It is found that the N2O molecule requires +0.52, +0.88 and + 0.4 eV of activation energies through mentioned three reactions, respectively, to adsorb and decompose to N2 and O2. The parallel, lying-atop-011 and flat were stable forms with adsorption energies of -0.20 (-4.65), -0.19 (-4.53) and -0.18 (-4.46) and -0.19 eV (-4.53 kcal/mol), respectively. The achieved outcomes reveal that Silicon-embedded Graphene has a high potential to be used as a more efficient and green catalyst for the catalytic conversion of the air polluting gases in comparison to the Selenium-doped Graphene, Fe+, Manganese-embedded Graphene and Magnesium oxide (MgO) catalysts.Vine cuttings with six to eight unfolded leaves are utilized as is conventional in sweetpotato (Ipomoea batatas (L.) Lam.) seedling production. However, most vine cuttings wilt after transplanting into the field. Moreover, few researchers have examined the influence of photon flux density (PFD) provided by white or white plus red light-emitting diodes (LEDs) on sweetpotato plantlets. In this study, hydroponic sweetpotato (cv. Beniharuka) seedlings using single-node cutting were grown under 20 combinations of five levels of PFDs of 150, 200, 250, 300, and 350 μmol m-2 d-1 and four light qualities white LEDs with a red light to blue light ratio (RB ratio) of 0.9, white plus red LEDs with RB ratios of 1.2 and 2.2, respectively, and fluorescent lamp with an RB ratio of 1.8 as control, for 20 days under a controlled enviroment. Results showed that the number of newly developed leaves on hydroponic sweetpotato seedlings increased with time in a quadratic function, regardless of light quality. Fluorescent lamps led aruka) seedling production under a controlled environment.In vitro studies have demonstrated that platelet lysate (PL) can serve as an alternative to platelet-rich plasma (PRP) to sustain chondrocyte proliferation and production of extracellular matrix components in chondrocytes. The present study aimed to evaluate the direct effects of PL on equine articular chondrocytes in vitro in order to provide a rationale for in vivo use of PL. An in vitro cell proliferation and de-differentiation model was used primary articular chondrocytes isolated from horse articular cartilage were cultured at low density under adherent conditions to promote cell proliferation. Chondrocytes were cultured in serum-free medium, 10% foetal bovine serum (FBS) supplemented medium, or in the presence of alginate beads containing 5%, 10% and 20% PL. Cell proliferation and gene expression of relevant chondrocyte differentiation markers were investigated. The proliferative capacity of cultured chondrocytes, was sustained more effectively at certain concentrations of PL as compared to that with FBS. In addition, as opposed to FBS, PL, particularly at percentages of 5% and 10%, could maintain the gene expression pattern of relevant chondrocyte differentiation markers. In particular, 5% PL supplementation showed the best compromise between chondrocyte proliferation capacity and maintenance of differentiation. The results of the present study provide a rationale for using PL as an alternative to FBS for in vitro expansion of chondrocytes for matrix-assisted chondrocyte implantation, construction of 3D scaffolds for tissue engineering, and treatment of damaged articular cartilage.The effects of different doses of orally administered sildenafil on pulmonary haemodynamics in dogs with pulmonary hypertension (PH) have not been documented in an invasive and quantitative manner. In this study, we examined the effects of oral sildenafil using a canine model of chronic embolic PH (CEPH). This CEPH model was created by repeatedly injecting microspheres through a catheter into the pulmonary artery under general anaesthesia at regular weekly intervals over several months. The CEPH dogs received 1, 2 or 4 mg/kg of sildenafil orally twice a day for seven days. Then, haemodynamic measurements including pulmonary artery pressure (PAP), systemic artery pressure (SAP), pulmonary artery wedge pressure (PAWP), right atrial pressure (RAP) and cardiac output (CO) were obtained after seven days of sildenafil administration via right heart catheterisation and oscillometric blood pressure measurements. Geneticin inhibitor Sildenafil was well tolerated in this study. Sildenafil administered at doses of 2 and 4 mg/kg significantly decreased systolic PAP compared with before administration. In addition, all doses of sildenafil significantly decreased the mean and diastolic PAP. Furthermore, 4 mg/kg of sildenafil significantly decreased PAP compared with 1 mg/kg. Sildenafil also significantly decreased pulmonary vascular resistance without notable changes in SAP or systemic vascular resistance. The PAWP, RAP and CO did not increase significantly at any doses. In conclusion, the oral administration of sildenafil to CEPH models decreased PAP in a dose-dependent manner.
Atrial natriuretic peptide (ANP), which is released by the heart in response to acute cardiac stretch, possesses cardiac electrophysiological properties that include modulation of ion channel function and repolarization. However, data regarding whether ANP can directly modulate electrical instability or arrhythmias are largely lacking.

This study sought to determine whether ANP modifies onset or electrophysiological characteristics of ventricular fibrillation (VF) induced by severe hypokalemia in an isolated heart model.

Langendorff-perfused rabbit hearts in the absence and presence of 10nM ANP (n=9 in each group) were subjected to a low potassium (K
) perfusate (1.2mMK
). Left ventricular (LV) epicardial monophasic action potential (MAP) and pressure were monitored continuously. Incidence and time to onset of VF and dominant frequency during VF determined by spectral analysis were evaluated.

ANP did not alter ventricular repolarization (MAP duration) or LV pressure during perfusion with physiologic, K
-containing solution.
