Salmonella Enteritidis (S. Enteritidis) are found in animals, humans, and environment. In addition, S. Enteritidis draws attention to the public health concerns due to carriage of antibiotic resistance traits. For these reasons, the prevalence and antibiotic resistance patterns of S. Enteritidis are significant issues with regard to public health. To address this issues, a total of 24 strains of S. Enteritidis from 164 samples collected from several slaughterhouses in Gyeong-Nam province in order for antibiotic resistance profiles. Subsequently, we characterized the genotyping by random amplification polymorphic DNA (RAPD)-PCR. As a result, very high level of resistance to protein synthesis inhibition antibiotics and most isolates were susceptible to others. Six random primers were used for RAPD-PCR to reveal genotypes of S. Enteritidis isolates. One of the primer, P1245, generated 147 distinct RAPD-PCR fragments ranging from 400∼3000 bp. The number of RAPD-PCR products ranged from 4 to 8 for this primer. The RAPD-PCR fragments could be placed these strains into 3 subgroups and 2 classes by UPGMA cluster analysis. Interestingly, several S. Enteritidis that isolated from different slaughterhouses showed same genotype. These results showed only limited genetic variation among the isolates, those were grouped into a few different patterns of antibiotic resistance.

Premature ovarian failure (POF) is a condition in which the ovarian functions of hormone production and oocyte development become impaired before the typical age for menopause. POF and early menopause are present in a broad spectrum of gonad dysgenesis, from a complete cessation of ovarian function to an intermittent follicle maturation failure. Actually POF has been identified as a genetic entity (especially chromosome X), but data on genetic factors of premature menopause are limited. Until now, several cases revealed that inactivation of X chromosomes has an effect on ages of premature menopause and females with balanced or unbalanced X-autosome translocations can have several reproductive problems. On the other hand, there have been a few data that was caused by autosome-autosome translocation can lead. Therefore we report a relevant case of POF with translocation between chromosomes 1 and 4. She had her first menstrual period at the age of 12, and after 7 years she stopped menstruation. Chromosomal analysis showed 46, XX, t (1;4) (p22.3;q31.3). While evaluating this rare case, we could review various causes (especially genetic factors) of POF. To remind clinicians about this disease, we report a case of POF caused by autosomeautosome translocation with a literature review. (J Menopausal Med 2015;21:112-114)

We intended to develope an vibrating intravascular lung assist device(VIVLAD) in order to exchange of efficiently gas transfer of oxygen and carbon dioxide exchange requirements for end-stage acute respiratory distress syndrome (ARDS) patients. However, the clinical study, concluded that more gas exchange was needed for intravascular oxygenation to be clinically effective in ARDS treatment. In this study, we tried to enhance gas exchange on the VIVLAD by using microencapsulation of hemoglobin, as the microencapsulation of hemoglobin reduces blood hemolysis, and perfluorocarbon emulsion(PFC emulsion). As a result, it was shown that the oxygen transfer of hemosome and blood/hemosome mixed solution were higher than that of whole blood. Also, it showed that the carbon dioxide transfer of whole blood/PFC emulsion mixed solution was higher than that of others. Therefore, we determined that hemosome and PFC emulsion could increase oxygen transfer and carbon dioxide transfer, respectively.

In this study, we tried to improve oxygen transfer rate and reduce pressure drop on intravascular lung assist device with microencapsulation of red blood cells, because microcapsulation of red cells reduce blood hemolysis. Hemoglobin was purified from outdated human red blood cells used. Phospholipid was purified from egg yolk. The hemosome was prepared by encapsulation of hemoglobin with phospholipid multilayer, using rotary vacuum evaporator. The function of hemosome and hemosome/blood mixed solution was tested by measuring oxygen dissociation curve using blood gas analyzer. Also we were measured about hemolysis of hemosome, hemosome/blood mixed solution and blood by absorptivity method. As a results, the oxygen dissociation curve of hemosome and hemosome/blood mixed solution showed the same figure as the curve of normal red blood cells. Also, the hemolysis of hemosome and hemosome/blood mixed solution was measured less than normal red blood cell. Therefore, the oxygen transfer rate showed high use of hemosome, and hemosome/blood mixed solution rather than normal blood. Because microen- capsulation of normal red blood cells prevent hemolysis of normal red blood cells.

A new lignan, (7R,7'R,8R,8'R)-8-hydroxypinoresinol 8-O-β-D-glucopyranoside 4'-methyl ether (7), was isolated from the flowers of Osmanthus fragrans var. aurantiacus along with six known lignans: (+)-phillygenin (1), phillyrin (2), (−)-phillygenin (3), (−)-epipinoresinol-β-D-glucoside (4), taxiresinol (5), and (−)-olivil (6). The structure of the new compound was elucidated on the basis of 1D- and 2D-NMR spectroscopic analysis and specific rotation data. The compounds isolated from the flowers of O. fragrans var. aurantiacus were evaluated for inhibitory activities on nitric oxide production in lipopolysaccharide-stimulated macrophage RAW 264.7cells. (+)-Phillygenin (1), phillyrin (2), and (−)-phillygenin (3) exerted the strongest inhibitory activities on NO production with IC50 values of 25.5, 18.9, and 25.5 μM, respectively. These compounds may prove beneficial in the development of natural agents for prevention and treatment of inflammatory diseases.

<B>Objective</B><P>Heterogeneous nuclear ribonucleoprotein A1 (HNRNPA1), serine/arginine-rich splicing factor 1 (SRSF1), and SRSF3 are splicing regulators associated with oncogenesis. However, the alterations of SF proteins and their diagnostic values in cervical cancer are unclear. To apply SFs clinically, effective marker selection and characterization of the target organ properties are essential.</P><B>Materials and Methods</B><P>We concurrently analyzed HNRNPA1, SRSF1, SRSF3, and the conventional tumor markers squamous cell carcinoma antigen (SCCA) and carcinoembryonic antigen (CEA) in cervical tissue samples (n = 127) using semiquantitative immunoblotting. In addition, we compared them with p16 (cyclin-dependent kinase inhibitor 2A [CDKN2A]), which has shown high diagnostic efficacy in immunohistochemical staining studies and has been proposed as a candidate protein for point-of-care screening biochemical tests of cervical neoplasia.</P><B>Results</B><P>HNRNPA1, higher molecular weight forms of SRSF1 (SRSF1-HMws), SRSF3, CEA, and p16 levels were higher (<I>P</I> < 0.05) in cervical carcinoma tissue samples than in nontumoral cervical tissue samples. However, the levels of SRSF1-Total (sum of SRSF1-HMws and a lower molecular weight form of SRSF1) and SCCA, a commonly used cervical tumor marker, were not different between carcinoma and nontumoral tissue samples. In paired sample comparisons, HNRNPA1 (94%) showed the highest incidence of up-regulation (carcinoma/nontumor, >1.5) in cervical carcinoma, followed by p16 (84%), SRSF1-HMws (69%), SRSF3 (66%), CEA (66 %), SCCA (32%), and SRSF1-Total (31%). HNRNPA1 (92%) and p16 (91%) presented the two highest diagnostic accuracies for cervical carcinoma, which were superior to those of SRSF3 (75%), SRSF1-HMws (72%), CEA (72%), SCCA (59%), and SRSF1-Total (55%).</P><B>Conclusions</B><P>Our results identified that HNRNPA1 is the best diagnostic marker among the SFs and conventional markers given its excellent diagnostic efficacy for cervical carcinoma, and it has a p16-comparable diagnostic value. We suggest that HNRNPA1 is an additional effective target protein for developing cervical cancer detection tools.</P>
