state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor fibers. In this review, we assess the viability of electron beam, gamma-ray, ultra-violet, and plasma treatments with a... -

Adipose tissue-derived stem cell (ASCs) are an attractive source of stem cells with therapeutic applicability in various fields for regenerating damaged tissues because of their stemness characteristics. However, little has reported on evaluating adverse responses caused by human ASC therapy. Therefore, in the present study, a clinical assessment after human ASC transplantation into dogs was undertaken. A total of 12 healthy male dogs were selected and divided into four groups: saline infusion,... -

Our study aims to determine the metabolism and excretion of novel pulmonary-targeting docetaxel liposome (DTX-LP) using the in vitro and in vivo animal experimental models. The metabolism and excretion of DTX-LP and intravenous DTX (DTX-IN) in New Zealand rabbits were determined with ultra-performance liquid chromatography tandem mass spectrometry. We found DTX-LP and DTX-IN were similarly degraded in vitro by liver homogenates and microsomes, but not metabolized by lung homogenates.... -

The increased potential for vascular smooth muscle cell (VSMC) growth is a key abnormality in the development of atherosclerosis and post-angioplasty restenosis. Abnormally high activity of plate-let-derived growth factor (PDGF) is believed to play a central role in the etiology of these pathophy-siological situations. Here, we investigated the anti-proliferative effects and possible mechanism(s) of murrayafoline A, a carbazole alkaloid isolated from Glycosmis stenocarpa Guillamin (Rutaceae), on... -

Under some pathological conditions as bile flow obstruction or liver diseases with the enterohepatic circulation being disrupted, regurgitation of bile acids into the systemic circulation occurs and the plasma level of bile acids increases. Bile acids in circulation may affect the nervous system. We examined this possibility by studying the effects of bile acids on gating of neuronal (N)-type Ca2＋ channel that is essential for neurotransmitter release at synapses of the peripheral and central... -

Gaegurin 4 (GGN4), an antimicrobial peptide isolated from a Korean frog, is five times more potent against Gram-positive than Gram-negative bacteria, but has little hemolytic activity. To understand the mechanism of such cell selectivity, we examined GGN4-induced K＋ efflux from target cells, and membrane conductances in planar lipid bilayers. The K＋ efflux from Gram-positive M. luteus (2.5</SUP>Ռg/ml) was faster and larger than that from Gram-negative E. coli (75Ռg/ml), while... -

Lysophosphatidylcholine (LPC), which accumulates in atherosclerotic arteries, has been reported to inhibit endothelium-dependent relaxation (EDR) in many different species. However, the underlying mechanism of LPC-induced inhibition of EDR is still uncertain. In the present study, we measured simultaneously both isometric tension and cytosolic free Ca2 ([Ca2]i) in rabbit carotid strips, and examined the effect of LPC on tension and [Ca2]i. In carotid strips with... -

The present study were designed to characterize the action mechanisms of acetylcholine (ACh)- induced endothelium-dependent relaxation in arteries precontracted with high K (70 mM). For this, we simultaneously measured both muscle tension and cytosolic free Ca2 concentration ([Ca2]i), using fura-2, in endothelium-intact, rabbit carotid arterial strips. In the artery with endothelium, high K increased both [Ca2]i and muscle tension whereas ACh (10μM)... -

The aim of this study was to clarify the mechanism of the inhibitory action of carbon monoxide (CO) on contraction, by measuring cytosolic Ca2 level ([Ca2]i) and ionic currents in guinea-pig ileum. CO (10%) inhibited 40 mM KCl-induced contraction and this effect was blocked by ODQ (1μM), a soluble guanylyl cyclase (sGC) inhibitor. CO inhibited the 40 mM KCl-induced contraction without changing [Ca2]i. Cumulative addition of KCl induced a graded increase in [Ca2]i... -

본 연구에서는 세포내의 칼슘이온과 결합하여 형광을 발하는 형광색소 fura 2를 이용하여 세포내의 칼슘이은 농도를 측정함과 동시에 장력을 측정하였으며 이에 대한 카페인과 고농도의 칼륨의 영향을 정토하였다. 72.7 mM의 칼륨 이온은 장력과 세포내 칼슘이온농도에서 각각 지속적 인 증가를 보여주었으며, 20 mM의 카페인은 일과성의 빠른 세포내의 칼슘이은농도의 증가에 이어 감소를 보여주었으나 기본치 보다는 높았다. 그러나, 장력에 있어서는 카페인은 일과성의 증가에 이어 기본 장력보다 낮은 감소를 보여주었다. 한편... -

Knowledge of the concept of osseointegration has enhanced the success of dental implants owing to improved understanding of the concept of bone stress and bone response. Longitudinal clinical studies report 10-year successrates of 81-85% for implants in the maxilla and 98-99% for implants in the anterior mandible1). In 1989, the main causes of implant failure were the selection of inappropriate patients and the accumulation of residue owing to the use of improper prosthetic restoration... -

This study was to investigate defense mechanisms on cassava induced by salicylic acid formulation (SA) against anthracnose disease. Our results indicated that the SA could reduce anthracnose severity in cassava plants up to 33.3% under the greenhouse condition. The β-1,3-glucanase and chitinase enzyme activities were significantly increased at 24 hours after inocula- tion (HAI) and decrease at 48 HAI after Colletotrichum gloeosporioides challenge inoculation, respectively, for cassava treated... -

Botrytis cinerea, which causes gray mold disease in more than 200 plant species, is an economically important pathogen that is mainly controlled by synthetic fungicides. Synergistic fungicide mixtures can help reduce fungicide residues in the environment and mitigate the development of fungicide-resistant strains. In this study, we screened microbial culture extracts on Botrytis cinerea to identify an antifungal synergist for tebuconazole. Among the 4,006 microbial extracts screened in this... -
Inhibitory Effect of Moriniafungin Produced by Setosphaeria rostrata F3736 on the Development of Rhizopus Rot

Rhizopus rot is a serious postharvest disease of various crops caused by Rhizopus spp. and controlled mainly by synthetic fungicides. We detected the antifungal activity of a culture extract of Setosphaeria rostrata F3736 against Rhizopus oryzae. The active ingredient was identified as moriniafungin, a known sordarin derivative, which showed minimum inhibitory concentrations of 1-8 μg/ml against Colletotrichum spp. and 0.03-0.13 μg/ml against Rhizopus spp. in vitro. Moriniafungin showed... -

Essential oils (EOs) have gained a renewed interest in many disciplines such as plant disease control and medicine. This review discusses the components of ginger EOs, their mode of action, and their potential nanotechnology applications in controlling tropical plant diseases. Gas chromatography-mass spectroscopy (GC-MS), high-performance liquid chromatography, and headspace procedures are commonly used to detect and profile their chemical compositions EOs in ginger. The ginger EOs are composed... -
