Ihsan Ali, Syed Zahid Ali Shah, Yi Jin, Zhong-Shu Li, Obaid Ullah, Nan-Zhu Fang 대한수의학회 Journal of Veterinary Science 9 Pages
대한수의학회 Journal of Veterinary Science 2017, 제 18권 제 1호 1 1-9 (9 pages)
Excessive production of reactive oxygen species (ROS) and endoplasmic reticulum (ER) stress-mediated responses are critical to embryonic development in the challenging in vitro environment. ROS production increases during early embryonic development with the increase in protein requirements for cell survival and growth. The ER is a multifunctional cellular organelle responsible for protein folding, modification, and cellular homeostasis. ER stress is activated by a variety of factors including... -

Seventeen dogs were treated with L-ornithin-L-aspartate (LOLA; experimental group). Three dogs were treated with lactulose recognized therapy (control group). Following LOLA administration, 15 dogs experienced a significant decrease in ammonia level (p ＜ 0.05) and showed clinical signs of improvement. However, there were no clinical signs of improvement in two dogs, even though the ammonia level decreased. Conversely, the clinical signs of the control group also improved and the ammonia level... -

대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 4호 12 359-367 (9 pages)
In the present investigation, the toxicopathological effects of ochratoxin A of 0.5 ppm on hematobiochemical parameters of broilers were studied with efficacy of dietary concentration of probiotic containing yeast culture Saccharomyces boulardii of 10 mg/kg of feed. One hundred twenty day old chicks were randomly divided into four groups, thirty chicks each. Groups A and C chicks were offered normal feed and that added with probiotic Saccharomyces boulardii respectively. The birds in group B... -
Application of biotechnological tools for coccidia vaccine development
Wongi Min, Rami A. Dalloul, Hyun S. Lillehoj 대한수의학회 Journal of Veterinary Science 10 Pages
대한수의학회 Journal of Veterinary Science 2004, 제 5권 제 4호 1 279-288 (10 pages)
Coccidiosis is a ubiquitous intestinal protozoan infection of poultry seriously impairing the growth and feed utilization of infected animals. Conventional disease control strategies have relied on prophylactic medication. Due to the continual emergence of drug resistant parasites in the field and increasing incidence of broiler condemnations due to coccidia, novel approaches are urgently needed to reduce economic losses. Understanding the basic biology of host-parasite interactions and... -

The study was conducted to investigate the role of vitamin E in the high altitude hypoxia-induced damage to the intestinal barrier in rats. Sprague-Dawley rats were divided into control (Control), high altitude hypoxia (HH), and high altitude hypoxia＋vitamin E (250 mg/kg BW*d) (HV) groups. After the third day, the HH and HV groups were placed in a hypobaric chamber at a stimulated elevation of 7000 m for 5 days. The rats in the HV group were given vitamin E by gavage daily for 8 days. The other... -

3-Nitropropionic acid (3-NP) inhibits electron transport in mitochondria, leading to a metabolic failure. In order to elucidate the mechanism underlying this toxicity, we examined a few biochemical changes possibly involved in the process, such as metabolic inhibition, generation of reactive oxygen species (ROS), DNA strand breakage, and activation of Poly(ADP-ribose) polymerase (PARP). Exposure of SK-N-BE(2)C neuroblastoma cells to 3-NP for 48 h caused actual cell death, while inhibition of... -

대한생리학회-대한약리학회 The Korean Journal of Physiology & Pharmacology 1999, Vol.3 No.6 12 631-640 (10 pages)
The present study investigated the stimulatory effects of iron (or ascorbate) on cyclosporine-induced kidney mitochondrial damage. Damaging effect of 50 μM cyclosporine plus 20 μM Fe2 on mitochondrial lipids and proteins of rat kidney and hyaluronic acid was greater than the summation of oxidizing action of each compound alone, except sulfhydryl oxidation. Cyclosporine and 100 μM ascorbate showed an enhanced damaging effect on lipids but not on proteins. The peroxidative action of... -

본 연구의 목적은 알코올사용 및 알코올중독증에 관한 우리나라의 독특한 민족 문화적 개념을 조사하여 진단에 이용하고자 함이다. 이를 위하여 민족지학적 조사연구방법 중 하나인 초점집단 연구방법을 이용하였 다. 본 연구에서 얻은 결과 및 결론은 다음과 같다. 1) 한국 사람들의 술에 대한 일반적인 인식은 술을 물질(substance)로서의 개념보다는 음식(food)으로서 보는 것이며, 음주 자체보다는 음주 후 발생하게 되는 문제들에 따라 술에 대한 인식을 달리 한다는 점이다. 2) 대인관계에 문제가 생김에도 불구하고 계속 술을... -
In Vitro Wheat Immature Spike Culture Screening Identified Fusarium Head Blight Resistance in Wheat Spike Cultured Derived Variants and in the Progeny of Their Crosses with an Elite Cultivar

Fusarium head blight (FHB) is a devastating fungal disease of wheat (Triticum aestivum L.). The lack of genetic resources with stable FHB resistance combined with a reliable and rapid screening method to evaluate FHB resistance is a major limitation to the development of FHB resistant wheat germplasm. The present study utilized an immature wheat spike culture method to screen wheat spike culture derived variants (SCDV) for FHB resistance. Mycotoxin concentrations determined by liquid... -

plant in liquid culture media. The ΔAbSte7 mutants could not efficiently detoxify cruciferous phytoalexin brassinin, possibly due to reduced expression of the brassinin hydrolase gene involved in detoxifying brassinin. Disruption of the AbSte7 gene also severely impaired fungal detoxification of reactive oxygen species. AbSte7 gene disruption reduced the enzymatic activity of cell walldegrading enzymes, including cellulase, β-glucosidase, pectin methylesterase, polymethyl-galacturonase, and... -
Histone Acetylation in Fungal Pathogens of Plants
한국식물병리학회 The Plant Pathology Journal 9 Pages
한국식물병리학회 The Plant Pathology Journal 2014, 30권 1호 1 1-9 (9 pages)
Acetylation of histone lysine residues occurs in different organisms ranging from yeast to plants and mammals for the regulation of diverse cellular processes. With the identification of enzymes that create or reverse this modification, our understanding on histone acetylation has expanded at an amazing pace during the last two decades. In fungal pathogens of plants, however, the importance of such modification has only just begun to be appreciated in the recent years and there is a dearth of... -
Research Articles : RNAseq-based Transcriptome Analysis of Burkholderia glumae Quorum Sensing
한국식물병리학회 The Plant Pathology Journal 11 Pages
한국식물병리학회 The Plant Pathology Journal 2013, 29권 3호 4 249-259 (11 pages)
Burkholderia glumae causes rice grain rot and sheath rot by producing toxoflavin, the expression of which is regulated by quorum sensing (QS). The QS systems of B. glumae rely on N-octanoyl homoserine lactone, synthesized by TofI and its cognate receptor TofR, to activate the genes for toxoflavin biosynthesis and an IclR-type transcriptional regulator gene, qsmR. To understand genome-wide transcriptional profiling of QS signaling, we employed RNAseq of the wild-type B. glumae BGR1 with... -
