  • This study was conducted to examine the role of the transcription factors (TFs) (RsMYB1 and mPAP1+B-Peru) in the regulation of anthocyanin biosynthesis in the ornamental torenia cv. Kauai rose. In this study, we could produce several putative transgenic lines overexpressing the TFs via Agrobacterium-mediated transformation, and presence of the TFs in the randomly selected five transgenic lines was confirmed using polymerase chain reaction (PCR). According to results of reverse transcription-PCR analysis (RT-PCR), the expression of the TFs in all transgenic lines and of the anthocyanin structural genes (CHS, F3H, DFR, and ANS) in all transgenic lines and WT plants were distinctly detectable. However, transcript levels of the structural genes expressed in the transgenic lines overexpressing TFs were significantly higher than those expressed in WT plants. Therefore, it is suggested that anthocyanin content in flowers of the transgenic torenia would be significantly higher than that in flowers of WT plants. Moreover, these results indicate that the TFs (RsMYB1 and mPAP1+B-Peru) could be exploited as potential anthocyanin regulatory TFs to enhance anthocyanin content in the other horticultural plants.

  • Idiopathic pulmonary alveolar proteinosis (PAP) is a rare disorder characterized by surfactant component accumulation in the alveolar space. Idiopathic PAP has recently been recognized as a autoimmune disease of impaired alveolar macrophage function caused by autoantibodies against granulocyte-macrophage colony-stimulating factor (GM-CSF). While whole lung lavage has been the standard treatment, not every patient shows a complete response. Subcutaneous injection or inhalation of GM-CSF is another promising treatment option for PAP. A 45-year-old patient visited our hospital for dyspnea, he was diagnosed as PAP and underwent whole lung lavage. Eighteen months later, the patient had not achieved complete remission in despite of initial response. After then he was administered with GM-CSF (5 ${mu}g/kg/day$, subcutaneous injection) for fivetimes a week during 2 months. Nine months later, the abnormal shadows in high-resolution computed tomography (HRCT) decreased and the patient fully recovered in forced vital capacity. After 60 months, the HRCT scan showed complete remission of PAP.

  • Purpose: This study was conducted to assess the agreement and differences between cervical self-sampling with a Kato device (KSSD) and gynecologist sampling for Pap cytology and human papillomavirus DNA (HPV DNA) detection. Materials and Methods: Women underwent self-sampling followed by gynecologist sampling during screening at two primary health clinics. Pap cytology of cervical specimens was evaluated for specimen adequacy, presence of endocervical cells or transformation zone cells and cytological interpretation for cells abnormalities. Cervical specimens were also extracted and tested for HPV DNA detection. Positive HPV smears underwent gene sequencing and HPV genotyping by referring to the online NCBI gene bank. Results were compared between samplings by Kappa agreement and McNemar test. Results: For Pap specimen adequacy, KSSD showed 100% agreement with gynecologist sampling but had only 32.3% agreement for presence of endocervical cells. Both sampling showed 100% agreement with only 1 case detected HSIL favouring CIN2 for cytology result. HPV DNA detection showed 86.2%agreement (K=0.64, 95% CI 0.524-0.756, p=0.001) between samplings. KSSD and gynaecologist sampling identified high risk HPV in 17.3% and 23.9% respectively (p=0.014). Conclusion: The self-sampling using Kato device can serve as a tool in Pap cytology and HPV DNA detection in low resource settings in Malaysia. Self-sampling devices such as KSSD can be used as an alternative technique to gynaecologist sampling for cervical cancer screening among rural populations in Malaysia.

  • Cancer is a major public health problem due to the jeavy disease burden, fatality and tendency for increased incidence. Of all cancer types, cervical cancer is reported to be the fourth most common cancer in women, and the seventh overall, with an estimated 528,000 new cases worldwide in 2012. It features a long preclinical phase with slowly progressing precancerous lesions such as CIN 2 and 3 and adenocarcinoma in situ. Therefore, screening programs such as with Pap smear tests may play an important role in cervical cancer prevention. The purpose of this study was to present results of a Pap smear screening survey for cervical cancer targeting women living in an urban area in the province of Mersin, located in the Mediterranean region of Turkey. This community-based descriptive study included women living at Akdeniz county of Mersin province. A total of 1,032 screened women between 30 and 65 ages within the routine screening programme constituted the study population. The mean age of the participants was $43.8{\pm}8.6$ (min. 30, max. 65) years. The percentage of the participants who had previously undergone smears was 40.6%. Epithelial cell changes were found in 26 (2.5%) participants, with ASC-US in 18 (1.7%), ASC-H in 2 (0.2%), LSIL in 5 (0.5%) and HSIL in 1 (0.1%). The most common clinical presentation together with epithelial changes was abnormal vaginal discharge. Taking into account the presence of women who had never undergone Pap test; it should be offered at primary level of health care in the form of a community-based service to achieve reduced morbidity and mortality rates.

  • Background: Anal intraepithelial lesions (AIL) are likely to represent a precursor for anal cancer. Women infected with human immunodeficiency virus (HIV) may be at higher risk of anal cancer but a screening program for AIL still is not routinely recommended. We here studied the relationship of dysplastic cells from cervical and anal cytology in HIV-infected women. Materials and Methods: This prospective study was conducted in Prapokklao Hospital, Thailand during 2013-2014. Five hundred and ninety nine HIV-infected women were recruited. Participants who had cytological reports of equally or over "abnormal squamous/glandular cells of undetermined significance" (ASC-US) were classified as abnormal cervical or anal cytology. Descriptive statistics and logistic regression analysis were used to evaluate correlations between groups. Results: HIV-infected women with abnormal cervical cytology had 3.8 times more risk (adjusted odd ratio 3.846, 95% confidence interval 1.247-11.862, p-value. 019) for abnormal anal cytology. The major problem of the anal Pap test in this study was the inadequacy of the collected specimens for evaluation (34.4%, 206/599). Sensitivity, specificity, positive predictive value, negative predictive value and accuracy of cervical and anal Pap tests were 93.9/12.0, 87.3/96.9, 39.7/21.4, 99.4/94.1 and 88.1/91.4 percent, respectively. Conclusions: Abnormal cervical cytology in HIV-infected women indicates elevated risk for abnormal anal cytology. The sensitivity of the anal Pap test for detection of AIL 2/3 in HIV-infected women was quite low while specificity was excellent. Inadequacy of specimen collection for evaluation was a major limitation. Improvement of sample collection is recommended for future investigations.

  • Exogeneous application of pokeweed antiviral protein (PAP), a ribosomal-inacivating protein in the cell wall of Phytolacca americana (pokeweed) protects heterologous plants from viral and fungal infection. A cDNA clone of PAP introduced into Scrophularia buergeriana Miquel by thransformation with Agrobacterium tumefaciences. For plant transformation, explants were precultured on shoot induction medium without kanamycin for 2-5 day, and then they were cocultured with Agrobacterium for 10 minutes. The explants were placed on co culture medium in dark condition, $28^{\circ}C$ for 2days. After explants were washed in MS liquid medium, they were transferred into selection medium including kanamycin 50mg/L (MS salts+1mg/ l BAP+2mg/ l TDZ+0,2mg/ l NAA+MS vitamin+3% sucrose+0.8% agar, pH5.8). From PCR analysis, NPT II band was confirmed in transgenic plant genome and showed resistance against fungi in antifungal activity test. Micro assay to which protein extracted from transgenic line were added, revealed hyphae growth inhibition and no spore germination at high concentration. The characteristics of inhibited hyphae was represented transparent and thin. Expression of PAP in transgenic plants offers the possibility of developing resistance to viral and fungal infection.

  • Objective: Examine the effects of supplementing bahiagrass hay (BG) with potentially anthelmintic quantities of hays of perennial peanut (PEA) or sericea lespedeza (LES) or seeds of velvet bean (Mucuna pruriens L.; MUC) or papaya (PAP) on the intake and nutritive value (Experiment 1), and the performance and parasite burden (Experiment 2) of goats. Methods: In Experiment 1, 38 male goats ($27.4{\pm}5.7kg$ body weight) were randomly assigned to each of 5 treatments: i) BG alone and BG plus; ii) PEA; iii) LES; iv) MUC; and v) PAP. Goats were fed for ad libitum consumption and adapted to the diets for 14 d followed by 7 d of measurement. The PEA, LES, MUC (50%, 50%, and 10% of the diet dry matter [DM], respectively), and PAP (forced-fed at 10 g/d) were fed at rates that would elicit anthelmintic effects. In Experiment 2, goats remained in the same treatments but were allocated to 15 pens (3 pens per treatment) from d 22 to 63. All goats were infected with parasites by grazing an infected bahiagrass pasture from 0800 to 1500 h daily and then returned to the pens. Results: Dry matter intake tended to be greater in goats fed PEA and LES than those fed BG (757 and 745 vs 612 g/d, respectively). Digestibility of DM (59.5% vs 54.9%) and organic matter (60.8% vs 56.0%) were greater in goats fed MUC vs BG, respectively. In Experiment 2, feeding PAP, LES, and PEA to goats reduced nematode fecal egg counts by 72%, 52%, and 32%, reduced abomasal adult worm counts by 78%, 52%, and 42%, and decreased plasma haptoglobin concentrations by 42%, 40%, and 45% relative to feeding BG alone, respectively. Conclusion: Supplementation with PEA, LES, and PAP decreased the parasite burden of goats but did not increase their performance. PAP was the most effective anthelmintic supplement.

  • Background: Pulmonary hypertension is considered as a poor prognosis factor in patients with chronic obstructive pulmonary disease (COPD). There has been reported brain natriuretic peptide (pro-BNP) is related with increased right ventricular (RV) workloads. However, there are few studies that evaluate the relationship between BNP and pulmonary arterial pressure (PAP), RV function and St. George Respiratory Questionnaire (SGRQ) score in patients with COPD, and the effects of angiotensin converting enzyme inhibitor (ACEI) on these parameters. Methods: Pulmonary function test, echocardiography, blood BNP, and SGRQ score were evaluated in stabilized moderate degree COPD patients ($FEV_1$/FVC< 70%, $50%{\leq}FEV_1$ < 80%) aged 45 years and over, without worsening of symptoms within recent 3 months. After treating with ramipril 10 mg for 3 months, the same evaluation was repeated. Results: Twenty-two patients were included in this study. BNP was significantly correlated with PAP (Pearson coefficient ${\rho}=0.51$, p=0.02), but not with RV ejection fraction (EF) and predicted $FEV_1%$. The values for predicted $FEV_1%$ showed significant correlation with SGRQ total score and activity score, but not with BNP or PAP. After ramipril treatment, PAP showed significant decrease ($42.8{\pm}8.1$ vs. $34.5{\pm}4.5mm$ Hg p=0.0003), tricuspid annular plane systolic excursion significant increase ($21.5{\pm}3.3$ vs. $22.7{\pm}3.1mm$ p=0.009). BNP showed a tendency to decrease without statistical significance ($40.8{\pm}59.6$ vs. $18.0{\pm}9.1pg/mL$ p=0.55). SGRQ scores showed no significant change. Conclusion: BNP showed significant correlation with resting PAP, which means BNP could be used as markers for pulmonary hypertension. Treatment with ACEI didn't show significant change in the level of BNP, while pulmonary hypertension and RV function were improved.

  • Background: The burden of breast and cervical cancer is changing over time in developing countries. Regular screening is very important for early detection and treatment. In this study, we assessed inequalities in breast and cervical cancer screening rates in women according to household wealth status, and analyzed the potential predictors associated with a low cancer screening rate in Jordan. Materials and Methods: A nationwide populationbased cross-sectional survey collected information on different variables at the national level. All ever-married women (the phrase is used throughout the text to refer to women who had ever married) aged 15-49 years were included in the survey. Analysis of breast self-examination (BSE) and clinical breast examination (CBE) at least once in the previous year was carried out in 11,068 women, while lifetime Pap-smear testing was carried out in 8,333 women, aged 20-49 years. Results: Over 39% and 19% of ever-married Jordanian women reported having undergone a breast examination during the previous year and Pap smear examination at least once in their lifetime, respectively. The rate of BSE in the previous year was 31.5%, that of CBE in the previous year was 19.3%, and that of Pap smear examination at least once in life was 25.5%. The adjusted OR was higher for performing BSE (aOR 1.22, 95% CI 1.04-1.43), undergoing CBE (aOR 1.31, 95% CI 1.08-1.60) and undergoing Pap smear examination (aOR 2.38, 95% CI 1.92-2.93) among women in the highest wealth-index quintile as compared to those in the lowest quintile. The concentration index was 0.11 for BSE, 0.01 for CBE, and 0.27 for Pap smear examination. Women in their twenties, living in rural or the southern region of Jordan, with an elementary school education or less, who listened to the radio or read the newspaper not more than a few times a year, and nulliparous women were less likely to undergo breast and cervical cancer screening. Conclusions: The rates of breast and cervical cancer screening are low in Jordan. Reducing the sociodemographic and economic inequalities in breast and cervical cancer screenings requires concerted outreach activities for women living under socially deprived conditions.

  • $\gamma$-Glutamyl transpeptidase (GGT, EC 2.3.2.2.) catalyzes the transfer of the $\gamma$-glutamyl moiety from $\gamma$-glutamyl containing ompounds, notably glutathione (GSH), to acceptor amino acids and peptides. A second gene (GGTII) encoding GGT was previously isolated and characterized from the fission yeast Schizosaccharomyces pombe. In the present work, the GGTII-lacZ fusion gene was constructed and used to study the transcriptional regulation of the S. pombe GGTII gene. The synthesis of $\beta$-galactosidase from the GGTII-lacZ fusion gene was significantly enhanced by NO-generating SNP and hydrogen peroxide in the wild type yeast cells. The GGTII mRNA level was increased in the wild-type S. pombe cells treated with SNP. However, the induction by SNP was abolished in the Pap1-negative S. pombe cells, implying that the induction by SNP of GGTII is mediated by Pap1. Fermentable carbon sources, such as glucose (at low concentrations), lactose and sucrose, as a sole carbon source, enhanced the synthesis of $\beta$-galactosidase from the GGTII-lacZ fusion gene in wild type KP1 cells but not in Pap1-negative cells. Glycerol, a non-fermentable carbon source, was also able to induce the synthesis of $\beta$-galactosidase from the fusion gene, but other non-fermentable carbon sources such as acetate and ethanol were not. Transcriptional induction of the GGTII gene by fermentable carbon sources was also confirmed by increased GGTII mRNA levels in the yeast cells grown with them. Nitrogen starvation was also able to induce the synthesis of $\beta$-galactosidase from the GGTII-lacZ fusion gene in a Pap1-dependent manner. On the basis of the results, it is concluded that the S. pombe GGTII gene is regulated by oxidative and metabolic stress.
