Antifungal Activity of Extracellular Hydrolases Produced by Autolysing Aspergillus nidulans Cultures
Melinda Szilágyi,Fruzsina Anton,Katalin Forgács,유재혁,István Pócsi,Tamás Emri 한국미생물학회 2012 The journal of microbiology Vol.50 No.5
Carbon-starving Aspergillus nidulans cultures produce high activities of versatile hydrolytic enzymes and, among these,ChiB endochitinase and EngA β-1,3-endoglucanase showed significant antifungal activity against various fungal species. Double deletion of engA and chiB diminished the antifungal activity of the fermentation broths and increased conidiogenesis and long-term viability of A. nidulans, but decreased the growth rate on culture media containing weak carbon sources. Production of ChiB and EngA can influence fungal communities either directly due to their antifungal properties or indirectly through their effects on vegetative growth. Our data suggest saprophytic fungi as promising future candidates to develop novel biocontrol technologies.
Enforcement of the Human Right to Water through the Universal Periodic Review
Melinda Szappanyos 경북대학교 법학연구원 2012 법학논고 Vol.0 No.40
Though the complex system of human rights is thoroughly worked out and the protection of human rights is monitored and discussed by many organs within the system of the United Nations, the effectiveness of these monitoring procedures is often questioned by non‐governmental organizations, human rights activists, and also by human rights experts. To increase the effectiveness and make the procedures more transparent and simple, in 2006 one significant part of the universal protection underwent a major change: The Commission on Human Rights was replaced by the Human Rights Council. The latter organ became responsible for the execution of a new monitoring mechanism, the Universal Periodic Review. This paper attempts to examine whether this mechanism offers a new opportunity to enforce human rights that are not explicitly included in international treaties, especially the right to water.
Graphene nanoribbon devices at high bias
Philip Kim,Melinda Y Han 나노기술연구협의회 2014 Nano Convergence Vol.1 No.1
We present the electron transport in graphene nanoribbons (GNRs) at high electric bias conduction. When graphene is patterned into a few tens of nanometer width of a ribbon shape, the carriers are confined to a quasi-one-dimensional (1D) system. Combining with the disorders in the system, this quantum confinement can lead into a transport gap in the energy spectrum of the GNRs. Similar to CNTs, this gap depends on the width of the GNR. In this review, we examine the electronic properties of lithographically fabricated GNRs, focusing on the high bias transport characteristics of GNRs as a function of density tuned by a gate voltage. We investigate the transport behavior of devices biased up to a few volts, a regime more relevant for electronics applications. We find that the high bias transport behavior in this limit can be described by hot electron scattered by the surface phonon emission, leading to a carrier velocity saturation. We also showed an enhanced current saturation effect in the GNRs with an efficient gate coupling. This effect results from the introduction of the charge neutrality point into the channel, and is similar to pinch-off in MOSFET devices. We also observe that heating effects in graphene at high bias are significant.

One of the most extensively studied populations of multipotent adult stem cells are mesenchymal stem cells (MSCs). MSCs derived from the human umbilical cord vein (HUC-MSCs) are morphologically and immunophenotypically similar to MSCs isolated from bone marrow. HUC-MSCs are multipotent stem cells, differ from hematopoietic stem cells and can be differentiated into neural cells. Since neural tissue has limited intrinsic capacity of repair after injury, the identification of alternate sources of neural stem cells has broad clinical potential. We isolated mesenchymal-like stem cells from the human umbilical cord vein, and studied transdifferentiation-promoting conditions in neural cells. Dopaminergic neuronal differentiation of HUC-MSCs was also studied. Neural differentiation was induced by adding bFGF, EGF, dimethyl sulfoxide (DMSO) and butylated hydroxyanisole (BHA) in N2 Medium and N2 supplement. The immunoreactive cells for β-tubulin III, a neuron-specific marker, GFAP, an astrocyte marker, or Gal-C, an oligodendrocyte marker, were found. HUC-MSCs treated with bFGF, SHH and FGF8 were differentiated into dopaminergic neurons that were immunopositive for tyrosine hydroxylase (TH) antibody. HUC-MSCs treated with DMSO and BHA rapidly showed the morphology of multipolar neurons. Both immunocytochemistry and RT-PCR analysis indicated that the expression of a number of neural markers including neuroD1, β-tubulin III, GFAP and nestin was markedly elevated during this acute differentiation. While the stem cell markers such as SCF, C-kit, and Stat-3 were not expressed after neural differentiation, we confirmed the differentiation of dopaminergic neurons by TH/β-tubulin III positive cells. In conclusion, HUC-MSCs can be differentiated into dopaminergic neurons and these findings suggest that HUC-MSCs are alternative cell source of therapeutic treatment for neurodegenerative diseases.
