found between the frequency of apoptotic cells and the dose. The morphological findings in the irradiated groups were typical apoptotic fragments in the matrix region of the hair follicle, but the spontaneous existence of apoptotic fragments was rarely observed in the control group. In the presence of an apoptosis frequency between 2 and 14 per follicle, the relative biological effectiveness values of neutrons in small and large follicles were 2.09 ± 0.30 and 2.15 ± 0.18, respectively. -

of TYFRV were selected for further biological and molecular studies. Based on their reactions on Nicotiana tabacum plants, the isolates were separated into two groups, namely L (local infection) and N (systemic infection). The nucleotide sequences of the nucleoprotein (N) genes of the isolates were determined and compared with the homologous sequences in Genbank. No recombination evidence was found in the isolates using different recombination- detecting programs. In the phylogenetic tree, the... -

Jun-Gu Kang, Hee-Woo Lee, Sungjin Ko, Joon-Seok Chae 대한수의학회 Journal of Veterinary Science 12 Pages
대한수의학회 Journal of Veterinary Science 2018, 제 19권 제 1호 9 59-70 (12 pages)
Outer membrane proteins (OMPs) of Gram-negative bacteria constitute the first line of defense protecting cells against environmental stresses including chemical, biophysical, and biological attacks. Although the 43-kDa OMP (OMP43) is major porin protein among Bartonella henselae-derived OMPs, its function remains unreported. In this study, OMP43-deficient mutant B. henselae (Δomp43) was generated to investigate OMP43 function. Interestingly, Δomp43 exhibited weaker proliferative ability than... -

molecular function, cellular component, and biological processes. The most frequent biological processes influenced by the proteins were response to stress, transport, and establishment of localization. Furthermore, a network analysis of the proteins with altered expression in mammary tissues demonstrated that these factors are predominantly involved with binding and structural molecule activities. Vimentin and ㅁㅁα-enolase were central “functional hubs” in the network. Based on results from... -

대한수의학회 Journal of Veterinary Science 2015, 제 16권 제 2호 1 135-143 (9 pages)
Tea contains polyphenols and is one of the most popular beverages consumed worldwide. Because most tyrosinase inhibitors that regulate melanogenesis are phenol/catechol derivatives, this study investigated the inhibitory effects of Camellia sinensis water extracts (CSWEs), including black tea, green tea, and white tea extracts, on melanogenesis using immortalized melanocytes. CSWEs inhibited melanin accumulation and melanin synthesis along with tyrosinase activity in a concentration-dependent... -

Echinacea (E.) purpurea herb is commonly known as the purple coneflower, red sunflower and rudbeckia. In this paper, we report the curative efficacy of an Echinacea extract in ■-irradiated mice. E. purpurea was given to male mice that were divided into five groups (control, treated, irradiated, treated before irradiation & treated after irradiation) at a dose of 30 mg/kg body weight for 2 weeks before and after irradiation with 3 Gy of ■-rays. The results reflected the detrimental... -

The effects of carnosine and related compounds (CRCs) including anserine, homocarnosine, histidine, and β-alanine on monosaccharide autoxidation and H2O2 formation were investigated. The incubation of CRCs with D-glucose, D-glucosamine, and D, L-glyceraldehyde at 37oC increased the absorption maxima at 285 nm, 273 nm, and 290∼330 nm, respectively. D, L-glyceraldehyde was the most reactive sugar with CRCs. The presence of copper strongly stimulated the reaction of carnosine and anserine with... -

Human neutrophil elastase (HNElastase, EC 3.4.21.37), a causative factor of inflammatory diseases, was purified by Ultrogel AcA54 gel filtration and CM-Sephadex ion exchange chromatography. HNElastase was inhibited by phenylbutazone in a concentration dependent manner up to 0.4 mM, but as the concentration increased, the inhibitory effect gradually diminished. Binding of phenylbutazone to the human neutrophil elastase caused strong Raman shifts at 200, 440, and 1194 cm1. The peak at 1194... -

일부 malignant tumor에 Pt-complex의 일상 응용 과정에서 신장독성등의 심한 부작용이 문제점으로 지적되고 있다. 이 연구에서는 기존의 cisplatin보다 항암효과는 우수하면서, 부작용을 감소시킨 새로운 Pt-complex의 개발에 역점을 두었다. 본 연구에서 합성한 Pt(Ⅱ) complex는 carrier ligand로서 1,2-diaminocyclohexane(dach)을 사용하였고, leaving group으로는 diophosphine류인 1,2-bisdiphenylphosphinoethane(DPPE)을 도입하였으며, 물에 대한 용해도를 높이기 위해 dinitrate로 만들었다. 새로이 합성한... -

최근에 미나라아제비과 (Ranunculaceae)에 속하는 부자(Aconiti tuber)로부터 강심작용을 나타내는 성분을 분리하여 Higenamine이라 명명하였고 그 작용기전을 밝히려는 시도가 활발히 진행되고 있다. 그러나 생약제로 부터 얻을 수 있는 Higenamine은 극히 미량이고 그 과정 또한 복잡하다. 따라서 본 연구에서는 유효성분을 대량 얻기 위한 방법으로서 전합성(total Synthesis)을 시도하였으며 IR, UV, NMR 및 elemental 분석등을 통하여 합성된 물질을 확인하였으며 가토에 대하여 in vivo에서 혈압, 심박동수, 호흡 및 말초저항에... -
