Biocontrol of Soft Rot Caused by with Bacteriophage phiPccP-1 in Kimchi Cabbage.

has recently emerged as a widely infective and destructive pathogen causing soft-rot disease in various vegetables. Bacteriophage phiPccP-1 isolated from Pyeongchang, South Korea, showed lytic activity against Pco14 and two other species. The transmission electron microscopy and genome phylograms revealed that phiPccP-1 belongs to the genus, subfamily of the family.

Protective Effects on Central Nervous System by Acidic Polysaccharide of Panax ginseng in Relapse-Remitting Experimental Autoimmune Encephalomyelitis-Induced SJL/J Mice.

Bearing pathologic and clinical similarities to human multiple sclerosis (MS), experimental autoimmune encephalomyelitis (EAE) is used as a murine model to test potential therapeutic agents for MS. Recently, we reported the protective effects of an acidic polysaccharide of Panax ginseng (APG) in C57BL/6 strain-dependent EAE, a model of primary progressive MS. In this study, we extend our previous findings on the therapeutic capacity of APG in relapsing-remitting EAE (rr-EAE), the animal model to closely mimic recurrent inflammatory demyelination lesions of relapsing-remitting MS.

Comparison of the characteristics and multipotential and in vivo cartilage formation capabilities between porcine adipose-derived stem cells and porcine skin-derived stem cell-like cells.

Objective: To compare the characteristics and multipotential and in vivo cartilage formation capabilities of porcine adipose-derived stem cells (pASCs) with those of porcine skin-derived stem cell-like cells (pSSCs).

Animals: Three 6-month-old female pigs and four 6-week-old female athymic mice.

Procedures: Adipose and skin tissue specimens were obtained from each pig following slaughter and digested to obtain pASCs and pSSCs.

Antioxidant treatment during manipulation procedures prevents mitochondrial and DNA damage and enhances nuclear reprogramming of bovine somatic cell nuclear transfer embryos.

We tried to prevent the mitochondrial and DNA damage caused by mechanical stress-associated reactive oxygen species (ROS), and to improve the reprogramming of bovine somatic cell nuclear transfer (SCNT) embryos by antioxidant treatment during the manipulation procedures of SCNT. Bovine recipient oocytes and reconstituted oocytes were treated with antioxidants during manipulation procedures. The H2O2 level, mitochondrial morphology, membrane potential and apoptosis at the one-cell stage, and in vitro development and DNA methylation status of blastocysts were evaluated.

Isolation and identification of novel propoxyphenyl thiosildenafil found in natural health food product.

A novel phosphodiesterase-5 (PDE-5) inhibitor was found in a natural health food product. The previously unknown sildenafil analogue was isolated using preparative HPLC. The structure of the compound was elucidated using HPLC with diode array detection (DAD), time-of-flight mass spectrometry (TOF/MS), and nuclear magnetic resonance spectroscopy (NMR).

Mitochondrial and DNA damage in bovine somatic cell nuclear transfer embryos.

The generation of reactive oxygen species (ROS) and subsequent mitochondrial and DNA damage in bovine somatic cell nuclear transfer (SCNT) embryos were examined. Bovine enucleated oocytes were electrofused with donor cells and then activated by a combination of Ca-ionophore and 6-dimethylaminopurine culture. The H2O2 and ˙OH radical levels, mitochondrial morphology and membrane potential (ΔΨ), and DNA fragmentation of SCNT and in vitro fertilized (IVF) embryos at the zygote stage were analyzed.

Identification of a new tadalafil analogue found in a dietary supplement.

A new tadalafil analogue, acetaminotadalafil, was detected by HPLC in a bulk powder that is being used as an ingredient formanufacturing dietary supplements. The analogue was isolated by semi-preparative HPLC. A chemical structure of the new compound was elucidated by HPLC, LC-quadrupole time-of-flight mass spectrometry (LC-Q-TOF/MS), nuclear magnetic resonance (NMR), infrared (IR) and circular dichroism (CD) spectroscopy.

Experimental autoimmune encephalomyelitis: association with mutual regulation of RelA (p65)/NF-κB and phospho-IκB in the CNS.

Recently emerging evidence that the NF-κB family plays an important role in autoimmune disease has produced very broad and sometimes paradoxical conclusions. In the present study, we elucidated that the activation of RelA (p65) of NF-κB and IκB dissociation assumes a distinct role in experimental autoimmune encephalomyelitis (EAE) progression by altering IκB phosphorylation and/or degradation. In the present study of factors that govern EAE, the presence and immunoreactivity of nuclear RelA and phospho-IκB were recorded at the initiation and peak stage, and degradation of IκBα progressed rapidly at an early stage then stabilized during recovery.

An acidic polysaccharide of Panax ginseng ameliorates experimental autoimmune encephalomyelitis and induces regulatory T cells.

An acidic polysaccharide of Panax ginseng (APG), so called ginsan, is a purified polysaccharide. APG has multiple immunomodulatory effects of stimulating natural killer (NK) and T cells and producing a variety of cytokines that proved to diminish the proinflammatory response, and protect from septic lethality. To determine APG's role in the autoimmune demyelinating disease, we tested whether APG can regulate inflammatory and encephalitogenic response in experimental autoimmune encephalomyelitis (EAE), an animal model of human multiple sclerosis (MS).

Acidic polysaccharide of Panax ginseng as a defense against small intestinal damage by whole-body gamma irradiation of mice.

An acidic polysaccharide of Panax ginseng (APG), ginsan, has been reported to protect the hematopoietic system by increasing the number of bone marrow cells and spleen cells. Therefore, we evaluated the ability of APG to protect mice from radiation-induced damage of the small intestine. APG treatment caused the lengthening of villi and a numerical increase of crypt cells in the small intestine at 3.

Immunomodulatory effects of an enzymatic extract from Ecklonia cava on murine splenocytes.

We investigated whether the brown seaweed Alariaceae Ecklonia cava (E. cava) has immunological effects on splenocytes in vitro. For that purpose, we prepared an enzymatic extract from E.

Osmolarity at early culture stage affects development and expression of apoptosis related genes (Bax-alpha and Bcl-xl) in pre-implantation porcine NT embryos.

This study examined whether high osmolarity of culture medium at the early culture stage affects development and expression of apoptosis related genes (Bax-alpha and Bcl-xl) of porcine nuclear transfer (NT) and in vitro fertilization (IVF) embryos. NT and IVF embryos were divided into three groups and the basic medium was PZM-3 (260-270 mOsmol, control group). The control group of embryos was cultured in PZM-3 for whole culture period.

Vitrification of immature bovine oocytes by the microdrop method.

Development and apoptosis of pre-implantation porcine nuclear transfer embryos activated with different combination of chemicals.

Artificial activation of oocytes is a pre-requisite for successful cloning by nuclear transfer (NT). This study investigated effect of different combination of activation chemicals such as electric pulse (E), thimerosal (Thi) + dithiothreitol (DTT), 6-dimethylaminopurine (6-DMAP), or cycloheximide (CH) on the developmental ability and the frequency of apoptosis of porcine NT embryos during the culture in vitro. NT embryos activated with chemicals showed significantly higher developmental rate to blastocyst stage compared to embryos activated with E alone (21.

p53 and cell-cycle-regulated protein expression in small intestinal cells after fast-neutron irradiation in mice.

The involvement of the p53 gene in apoptosis of many cell types towards y-radiation is well established. However, little information is available on the relationship between p53 status and cells' ability to undergo apoptosis following exposure to fast neutrons. The aim of this study was to characterize the apoptotic pathway traveled by neutrons in mouse intestinal crypt cells.
