Background: Given that there are many Iranian women who have never had a Pap smear, this study was designed to develop and validate a measurement tool based on the Protection Motivation Theory to assess factors influencing the Iranian women's intention to perform first Pap testing. Materials and Methods: In this psychometric research, to determine the Content Validity Index (CVI) and the Content Validity Ratio (CVR), a panel of experts (n=10) reviewed scale items. Reliability was estimated through the Intraclass Correlation Coefficient (n=30) and internal consistency (n=240). Also, factor analysis (exploratory and conformity) was performed on the data of the sample women who had never had a Pap smear test (n=240). Results: A 26-item questionnaire was developed. The CVI and CVR scores of the scale were 0.89 and 0.90, respectively. Exploratory factor analysis loaded a 26-item with seven factors questionnaire (perceived vulnerability and severity, fear, response costs, response efficacy, self-efficacy, and protection motivation (or intention)) that jointly accounted for 72.76% of the observed variance. Confirmatory factor analysis indicated a good fit for the data. Internal consistency (range 0.70-0.93) and test-retest reliability (range 0.72-0.96) of sub-scales were acceptable. Conclusions: This study showed that the designed instrument was a valid and reliable tool for measuring the factors influencing the women's intention to perform their first Pap testing.

The purpose of this convergence study is to understand the knowledge of cervical cancer and its prevention of cervical cancer in unmarried women. 216 women were collected through self-report questionnaires and analyzed by SPSS program. In result, human papilomavirus vaccination was performed in 33.9%, pap test was performed in 7.9%. The human papilomavirus vaccination and pap test group were 6.7% and human papilomavirus vaccination or pap test group were 28.5%. According to the cervical cancer prevention activities, several differences were detected in the family history of cervical cancer, subjective norms of cervical cancer prevention, perceived behavioral control, and behavioral intention. Therefore, it is important to increase susceptibility of the prevention of cervical cancer in unmarried women, and it is important for the health professionals to perform the most meaningful support system preventing cervical cancer in unmarried women. In addition, various policies should be actively promoted that unmarried women participate in the prevention of cervical cancer actively.

Background: Few Iranian women take the Papanicolaou test despite its important role in preventing cervical cancer. This study aimed to determine the effectiveness of an educational intervention based on the protection motivation theory (PMT) variables and implementation intentions in the first and second Pap test practice among Iranian women. Materials and Methods: In this quasi-randomized controlled trial, 200 women who were referred to 30 primary health care clinics in Tehran were randomly selected. PMT variables and Pap test practice were measured at baseline and again after 3 and 15 months. The 4-week educational intervention program was conducted for the intervention group. Results: Following the intervention, the mean scores of self-efficacy, perceived vulnerability, and behavior intention variables were significantly higher in the intervention group when compared to the control group (p<0.05). No significant differences were found in the perceived severity, response efficacy, response cost, and fear between the two groups following the intervention. Higher percent of women in the intervention group had obtained first and second Pap test compared to the controls. Conclusions: The PMT and implementation intentions provide a suitable theory-based framework for developing educational interventions regarding Pap test practice in Iran.

Background: Cervical cancer is one of the ten most frequent cancers in Turkey. We here examined knowledge about cervical cancer in relation to Papanicolaou (Pap) testing among female primary health care workers in Hatay, a city is located in the south of Turkey. Materials and Methods: The study was completed on 261 women healthcare workers who were or had been sexually active and who accepted to participate to the study. The participants gave verbal informed consent and thereafter questionnaires prepared by the investigators were administered by personal interview. Results: Only 30.3% (n=79) of the participants regularly had a gynecologic examination. While 87.4% (n=228) of the participants reported that they had already heard about the Pap smear test, only 45.2% (n=118) had undergone this test. It was determined that had undergone an average of $1.66{\pm}0.89$ times (1-4) within the last five years. Some 56.0% (n=117) of the participants were well informed about the Pap smear test (p<0,001) and 81.1% (n=63) of the participants who regularly had gynecological examinations (p<0,001) had this test. Conclusions: For the early diagnosis of the cervical cancer, regularly having a Pap smear test is crucial. Healthcare workers should also demonstrate sensitivity about this issue. We think that the importance of the issue should be re-highlighted by organizing in-service training for female primary healthcare workers. Studies are warranted to determine the psychosociological factors that cause individuals to not have the test.

Background: ASC-US cases are managed according to the current American Society for Colposcopy and Cervical Pathology (ASCCP) guideline in which a human papillomavirus (HPV) test and repeat Pap smear are performed in the next 1 year. Colposcopy in cases of positive high risk HPV and persistent ASC-US or more in subsequent Pap smear is recommended. The HPV test is more expensive and still not currently a routine practice in Thailand. Objective: To identify the risk factors of persisted abnormal Pap smear and the colposcopic requirement rate in women with ASC-US. Materials and Methods: During 2008-2013, this study was conducted in Prapokklao Hospital, Chanthaburi, Thailand. Participants were women who attended gynaecology clinic for cervical cancer screening. Women who had cytological reports with ASC-US were recruited. During the study period, 503 cases were enrolled. Colposcopic requirement was defined as those who were detected with an ASC-US or more in subsequent Pap smears up to 1 year follow-up. Results: The colposcopic referral rate was 23.2 (85/365) percent at 12 months. Prevalence of cervical intraepithelial neoplasia (CIN) 2/3 was 3.3 (12/365) percent. Loss follow-up rate of subsequent Pap smear and colposcopic appointment were 27.4 (138/503) and 48.2 (41/85) percent, respectively. There was no invasive cancer. High risk factors for persisted abnormal Pap smears in subsequent test were premenopausal status, HIV infected patients and non-oral contraceptive pills (COC) users. Conclusions: Referral rate for colposcopy in women with ASC-US reports was rather high. Loss to follow-up rate was the major limitation. Immediate colposcopy should be offered for women who had high risk for silent CIN.

Pulmonary alveolar proteinosis (PAP) is a rare disease in children characterized by intra-alveolar accumulation of surfactant proteins, which severely reduces gaseous exchange. Whole lung lavage (WLL) is the preferred technique for the treatment of severe PAP. Herein, we present a pediatric case of PAP treated with WLL. An 11-year-old boy was admitted with the chief complaint of a dry cough lasting 6 months. He developed symptoms of dyspnea on exertion and had difficulty in climbing stairs. He was ultimately diagnosed with PAP through video-assisted thoracoscopic lung biopsy. As first-line of treatment for PAP, he underwent therapeutic WLL for each of his lungs on separate days. After a brief recovery, his symptoms gradually worsened; therefore, he underwent a second WLL. This is the first pediatric case of PAP relapse despite successful WLL in Korea.

Effects of four citrus flavonoids, hesperidin, naringin and their aglycones on phosphatidate phosphohydrolase(PAP, EC 3.1.3.3) activity were examined using isolated rat microsomes as an enzyme source. In addition, these flavonoids were tested to see whether they exert any influence on the proliferation and growth in cultured human hepatocytes HepG2 cells. Flavonoids at concentration up to $10{-4}M$ had no significant effect on the number of cells and cell proliferation by MTT cell growth assay method, whereas aglycone flavonoids, hesperetin and narigenin, at concentration of $10{-3}M$ significantly inhibited cell proliferation. Hesperetin inhibited PAP activity in a dose-dependent manner starting at concentration of $10{-5}M$. Narigenin at concentration of $10{-2}M$ inhibited PAP activity markedly, while the other flavonoids did not show any significant effect. The present study, therefore, demonstrated that aglycone flavonoids exerted portent effects on PAP activity and on cell proliferation.

Recently, with the advance of computing and networking technique, the high speed internet becomes widespread, however, it is still hard job to do streaming the media which requires high network bandwidth over the internet. Previous researches for streaming over the internet mainly proposed techniques that controls the QoS(Quality of Service) of the media in proportion to the network status. Though, this could be the solution for the service provider while the service user who wants constant QoS may not satisfy with variable QoS. In the paper, we propose a network adaptive prefetching technique, PAP, for guarantee of constant QoS. The PAP prefetches frames by increasing the frame transmission rate while the available network bandwidth is high. The PAP uses the prefetched frames to guarantee the QoS while the available network bandwidth is low and increases the playout interval to prevent buffer underflow. The experiment result shows that the proposed PAP could guarantee the constant QoS by prefetching the frames adaptively to the network bandwidth with the characteristic of video stream.

Objective: The study was conducted to investigate the dephosphorylation of Pseudomonas aeruginosa flagellin (PA FLA) by sweet potato purple acid phosphatase (PAP) and the effect of the enzyme on the flagellin-mediated inflammatory response in the A549 lung epithelial cell line. Methods: The activity of sweet potato PAP on PA FLA was assayed at different pH (4, 5.5, 7, and 7.5) and temperature (25℃, 37℃, and 55℃) conditions. The release of interleukin-8 (IL-8) and the activation of nuclear factor kappa- light-chain-enhancer of activated B cells (NF-κB) in A549 cells exposed to PA FLA treated with or without sweet potato PAP was measured using IL-8 and NF-κB ELISA kits, respectively. The activation of toll-like receptor 5 (TLR5) in TLR5-overexpressing HEK-293 cells exposed to PA FLA treated with or without sweet potato PAP was determined by the secreted alkaline phosphatase-based assay. Results: The dephosphorylation of PA FLA by sweet potato PAP was favorable at pH 4 and 5.5 and highest at 55℃. PA-FLA treated with the enzyme decreased IL-8 release from A549 cells to about 3.5-fold compared to intact PA FLA at 1,000 ng/mL of substrate. Moreover, PA-FLA dephosphorylated by the enzyme repressed the activation of NF-κB in the cells compared to intact PA FLA. The activation of TLR5 by PA-FLA was highest in TLR-overexpressing HEK293 cells at a substrate concentration of 5,000 ng/mL, whereas PA FLA treated with the enzyme strongly repressed the activation of TLR5. Conclusion: Sweet potato PAP has the potential to be a new alternative agent against the increased antibiotic resistance of P. aeruginosa and may be a new conceptual feed additive to control unwanted inflammatory responses caused by bacterial infections in animal husbandry.

This study was attempted to identify the factors influencing on cervical cancer screening acceptance using Pap smear in women over 20 years old. The subjects of this study were 192 screening acceptance group who visited health examination center. Data were collected by interview and self-administered questionnaire from April 22 through May 24, 2013. The results of this study as follows. Firstly, the response rate(45.8%) of non-screening acceptance group who is not a religion was significantly higher than the response rate(32.3%) of screening acceptance group($X^2=4.82$, p<.05). Secondly, the response rate(61.5%) of non-screening acceptance group who performed breast-feeding was significantly higher than the response rate(46.9%) of screening acceptance group($X^2=0.61$, p<.05). Thirdly, screening acceptance group who performed other screening was significantly higher 4.62 times than non-screening acceptance group(95% Cl=1.15-9.84, P=0.006). Based on the results of this study, it necessary to provide more cervical cancer screening information which can change the negative attitude among the public toward cancer screening acceptance using Pap smear.
