Synergistic effects have previously been observed for a natural compound, tetrandrine (TET), with fluconazole (FLC) in vitro and in the treatment of Candida albicans-infected mice. To investigate the mechanisms of these synergistic effects, 16 strains of C. albicans from the same parent but with different FLC sensitivities were examined using flow cytometry and fluorescent spectrophotometry. Rh...

The Pto serine/threonine kinase of tomato confers resistance to speck disease by recognizing strains of Pseudomonas syringae that express the protein AvrPto. Pto and AvrPto physically interact, and this interaction is required for activation of host resistance. We identified a second Pseudomonas protein, AvrPtoB, that interacts specifically with Pto and is widely distributed among plant pathoge...

In the present study, PC12 cells induced by 6-hydroxydopamine as a model of Parkinson's Disease, were used to investigate the protective effects of bone marrow-derived mesenchymal stem cells bone marrow-derived mesenchymal stem cells against 6-hydroxydopamine-induced neurotoxicity and to verify whether the mechanism of action relates to abnormal α-synuclein accumulation in cells. Results showed...

conclusions the high prevalence of tet (o) resistance gene along with new detection of tet (a) resistance gene in campylobacter spp. isolated from poultry carcasses revealed an extensive tetracycline resistance among campylobacter isolates from poultry in iran. it emphasized the need for cautious use of tetracycline in poultry production to decrease the extension of tetracycline-resistant campy...

We investigate the mechanical response of PC12 neurites subjected to a drag force imposed by a laminar flow perpendicular to the neurite axis. The curvature of the catenary shape acquired by an initially straight neurite under the action of the drag force provides information on both elongation and tension of the neurite. This method allows us to measure the rest tension and viscoelastic parame...

During the continuous culturing of neural PC12 cells, a drug hypersensitive PC12 mutant cell line (PC12m3) was obtained, which demonstrated high neurite outgrowth when stimulated by various drugs. When the immunosuppressant drug FK506 and nerve growth factor (NGF) were introduced to the PC12m3 cells, the frequency of neurite outgrowth increased approximately 40-fold for NGF alone. However, the ...

In the last decade, many studies have been conducted on tractor and agricultural machinery electrification. particular, electrification of power take-off (PTO)-powered implements could support benefits, such as improved comfort safety during implement connection, less noisiness, accurate control rotational speed, fuel consumption reduction. However, commercially available tractors do not genera...

Previous studies from our laboratory have demonstrated that Bcl-2 has a proapoptotic effect on neocarzinostatin (NCS)-treated PC12 pheochromocytoma cells. In the present study, we examine the mechanisms of this effect and demonstrate its relevance for the in vivo situation. Four hours after NCS treatment, a 23-kDa cleavage product of Bcl-2 was detected in whole cell lysates of bcl-2-transfected...

Objective(s): Stroke may cause severe neuronal damage. The sesamin have been demonstrated to possess neuroprotection by its antioxidant and anti-inflammatory properties. One sesamin derivative was artificially composited, 1, 2-bis [(3-methoxyphenyl) methyl] ethane-1, 2-dicaroxylic acid (MMEDA) had been developed to study its antioxidative activity and neuroprotection. Materials and Methods: The...

Introduction: Increased oxidative stress is widely accepted to be a factor in the development and progression of Alzheimer’s disease. Triazine derivatives possess a wide range of pharmacological activities including anti-oxidative and anti-in.ammatory actions. In this study, we aimed to investigate the possible protective effect of 3-thioethyl-5,6-dimethoxyphenyl-1,2,4-triazine (TEDMT) on H2O2-...
