The aim of this study was to examine the spouse effects on depressive symptom and suicidal thinking among the elderly aged 65 and over in Korea. The subjects selected from the database of the Fourth Korea National Health and Nutrition Examination Survey(KNHANES IV) conducted by Korea Centers for Disease Control and Prevention from 2007 to 2009. Those who were female, older, lower educated, or poorer were more likely to live alone than their counterparts respectively. The elderly living alone experienced depressive symptom as 2.0 times(OR=2.004, 95% CI=1.433, 2.803) as, and suicidal thinking as 1.6 times(OR=1.567, 95% CI=1.111, 2.211) as the elderly couples did, adjusting for socio-economic factor, health status factors, and health behaviors factors. As for the male subgroup, the elderly living alone experienced depressive symptom as 4.0 times(OR=3.997, 95% CI=2.066, 7.732) as, and suicidal thinking as 3.2 times(OR=3.181, 95% CI=1.535, 6.592) as the elderly couples did. On the other hands, there was no significant difference in depressive symptoms and suicidal thinking between the female elderly living alone and couples. The authors suggested policy interventions to promote the mental health of the male elderly living alone.

Background: We here examined the awareness of female health employees (doctors, nurses, midwives) working in primary health care service about cervical cancer and its risk factors. Additionally attitude and behavior for gynecologic examination and pap smear screening wwere researched. Materials and Methods: This cross-sectional, descriptive study con cerned female health employees working at primary health care services in two southern cities of Turkey, over a four month period in 2013. Participants were recently or previously sexually active research was explained and verbal informed consent was obtained face to face. The questionnaire consisted of two parts; socio-demographic characteristics and level of knowledge about cervical cancer and its risk factors. Results: The average age of the participants (midwives 43.7%, n=143; nurses 40.4%, n=132; doctors 6.4%, n=21; emergency medical technicians and others, 9.5%, n=31; total, n=327) was $30.9{\pm}6.41$ years. 64.2% (n=210) were working in Diyarbakir and 35.8% (n=117) in Batman. A large proportion reported low knowledge and inadequate screening practice Conclusions: Health employees should be better informed about the importance of screening for cancers, given their preventive roles for the general population.

Background: Polyps are common lesions in the gastrointestinal (GI) tract. Colon cancer is mostly a result of progression from polyps. The present study aimed to evaluate demographic, clinical, and histological characteristics of colorectal polyps in Iran, particularly neoplastic and advanced types. Materials and Methods: Over a period of 10 years, specimens of all colorectal polyps obtained from colonoscopy were studied. The variables subjected to statistical analysis were age, sex, and the chief clinical complaint of the patients who underwent colonoscopy, their motivation, and the site, size, and histological types of detected polyps. The level of significance was set at p value <0.05. Results: Data were obtained from a total of 352 patients. No difference was seen between male and female patients regarding histological types. Only in nine patients was screening the reason for colonoscopy. Almost two-thirds (66.2%) of the polyps were neoplastic. Familial polyposis syndrome and inflammatory bowel disease were seen in 4.3% and 3.0% of the patients with neoplastic polyps, respectively. Sites of polyps were the sigmoid, rectum, and descending colon in 40.1%, 34.5%, and 17% of the cases, respectively. The advanced type made up 58.8% of neoplastic polyps. Only 3.6% of the patients undergoing colonoscopy in the study period had biopsied polyps. Discussion: No difference was observed between male and female patients in terms of overall incidence of polyps, histological and anatomical profiles, and mean age distribution. Anatomical and histological profiles agreed with the studies performed in areas with a low risk of colon cancer. The findings show that colonoscopy was not performed when it was necessary. A meaningful increase in the number polyp biopsy cases and a corresponding decrease in polyp size in the last few years of the study can be associated with the presence of more GI specialist clinicians in hospital centers, and this holds out much hope for the further improvement of the situation in the future.

The age and growth of brown sole, Pleuronectes herzensteini were investigated from samples randomly collected in the East Sea of Korea from April, 2003 to March, 2004. Ages were determined from annuli in otoliths and annuli were formed between March and May once a year. Also, main spawning period were estimated between March and April, thus rings were considered as annual marks. The von Bertalanffy growth parameters estimated from a non-linear regression method were $L_{\infty}=37.2cm$, K=0.131/year, $t_0=-2.008years$ for female and $L_{\infty}=28.3cm$, K=0.177/year, $t_0=-2.135years$ for male, and the growth between female and male was different.

Objective: The purpose of this study was to quantitatively evaluate the cortical bone densities of the maxillary and mandibular alveolar processes in adults with different vertical facial types using cone-beam computed tomography (CBCT) images. Methods: CBCT images (n = 142) of adult patients (20-45 years) were classified into hypodivergent, normodivergent, and hyperdivergent groups on the basis of linear and angular S-N/Go-Me measurements. The cortical bone densities (in Hounsfield units) at maxillary and mandibular interdental sites from the distal aspect of the canine to the mesial aspect of the second molar were measured on the images. Results: On the maxillary buccal side, female subjects in the hyperdivergent group showed significantly decreased bone density, while in the posterior region, male subjects in the hyperdivergent group displayed significantly decreased bone density when compared with corresponding subjects in the other groups (p<0.001). Furthermore, the subjects in the hyperdivergent group had significantly lower bone densities on the mandibular buccal side than hypodivergent subjects. The maxillary palatal bone density did not differ significantly among groups, but female subjects showed significantly denser palatal cortical bone. No significant difference in bone density was found between the palatal and buccal sides in the maxillary premolar region. Overall, the palatal cortical bone was denser anteriorly and buccal cortical bone was denser posteriorly. Conclusion: Adults with the hyperdivergent facial type tend to have less-dense buccal cortical bone in the maxillary and mandibular alveolar processes. Clinicians should be aware of the variability of cortical bone densities at mini-implant placement sites.

The gossypol existed in cottonseed meal is a well known antispermatogenic agent which can impair reproductive performances of male fish as well as mammals. Two feeding experiments were conducted to examine a toxic effect of dietary supplementation of cottonseed meal on reproduction in juvenile olive flounder (the first experiment) for 19 weeks and growing olive flounder (the second experiment) for 26 weeks. After each feeding study, females and males were sampled for histological examination in gonads and liver to verify any negative effects by the dietary supplementation of cottonseed and soybean meal on reproduction. After two feeding trial, the gonad somatic index (GSI) of male and female (from the first feeding trial) were not significantly different among all the dietary treatments. The GSI values of female (from the second feeding trial) were not significantly different among all the dietary treatments. However, males fed cottonseed and soybean meal containing diets exhibited significantly lower GSI than that fed the control diet after the second feeding trial. Histological examination of gonads and liver of fish fed cottonseed and soybean meal did not show any negative effects compared to those of fish ffd the control diet. Hepatosomatic index of fish in the first and second feeding trials were not significantly different among all the dietary treatments. The findings in this study suggest that dietary supplementation of cottonseed and soybean meal up to 40% fish meal replacement might not deteriorate the gametogenesis of juvenile and growing olive flounder. However, the supplementation in diets over 30% fish meal replacement might reduce GSI of male in growing olive flounder.

We developed a polymerase chain reaction (PCR)-based molecular method for sexing and identification using sexual dimorphism between the Zinc Finger-X and -Y (ZFX-ZFY) gene and polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) for mitochondrial DNA (mtDNA) cytochrome B (CYTB) gene in meat pieces and commercial sausages from animals of different origins. Sexual dimorphism based on the presence or absence of SINE-like sequence between ZFX and ZFY genes showed distinguishable band patterns between male and female DNA samples and were easily detected by PCR analyses. Male DNA had two PCR products appearing as distinct two bands (ZFX and ZFY), and female DNA had a single band (ZFX). Molecular identification was carried out using PCR-RFLP of CYTB gene, and showed clear species classification results. The results yielded identical information on the sexes and the species of the meat samples collected from providers without any records. The analyses for DNA isolated from commercial sausage showed that pig was the major source but several sausages originated from chicken and Atlantic cod. Applying this PCR-based molecular method was useful and yielded clear sex information and identified the species of various tissue samples originating from livestock.

Objective: The objectives of this study were to investigate the relationship between the mRNA expression of adipocyte type fatty acid binding protein (A-FABP) and heart type FABP (H-FABP) in Thai native chicken crossbreeds and evaluate the level of exotic inclusion in native chicken that will improve growth while maintaining its relatively low carcass fat. Methods: The fat deposition traits and mRNA expression of A-FABP and H-FABP were evaluated at 6, 8, 10, and 12 weeks of age in 4 chicken breeds (n = 8/breed/wk) (100% Chee breed [CH] [100% Thai native chicken background], CH male and broiler female [Kaimook e-san1; KM1] [50% CH background], broiler male and KM1 female [Kaimook e-san2; KM2] [25% CH background], and broiler [BR]) using abdominal fat (ABF) and muscular tissues. Results: The BR breed was only evaluated at 6 weeks of age. At week 6, the CH breed had a significantly lower A-FABP expression in ABF and intramuscular fat (IF) compared with the other breeds. At 8 to 12 weeks, the KM2 groups showed significant upregulation (p<0.05) of A-FABP in both ABF and IF compared to the CH and KM1 groups. The expression of H-FABP did not follow any consistent pattern in both ABF and IF across the different ages. Conclusion: Some level of crossbreeding CH chickens can be done to improve growth rate while maintaining their low ABF and IF. The expression level of A-FABP correlate with most fat traits. There was no consistency of H-FABP expression across breed. A-FABPs is involved in fat deposition, genetic markers in these genes could be used in marker assisted studies to select against excessive fat accumulation.

Objective : Low back pain (LBP) is a global health problem that affects the productivity of the patients. Several factors such as individual, occupational, and psychosocial factors increase the risk of LBP. However, only a few studies investigated those factors, especially in middle adulthood in Indonesia. Indonesia is a country with a young population that has been rapidly developing in recent years. This study was conducted to find out the factors associated with LBP in middle adulthood. Methods : This study is a cross-sectional observational analytic study using a convenience sampling method with a total sample of 3005 respondents. Data were collected using a questionnaire which was then analyzed using the chi-square test, Kolmogorov-smirnov, Spearman's Rank, and logistic regression test. Results : From the result of this study, it was found that the 12-month prevalence of LBP in middle-aged adults was 44,29%. Female (odds ratio [OR], 1.3; 95% confidence interval [Cl], 1.098-1.545; p=0.002), lack of physical exercises (OR, 0.87; 95% Cl, 0.794-0.959; p=0.005), high body mass index (OR, 1.09; 95% Cl, 1.009-1.187; p=0.002), stress level (OR, 1.26; 95% Cl, 1.088-1.458; p=0.002), and years of work experience (OR, 1.1; 95% Cl, 1.001-1.225; p=0.047) were determined as risk factors that significantly associated with LBP. Conclusion : LBP is quite common among middle-aged adults in Indonesia. Female gender, higher body mass index, lack of physical activity, stress level, and years of work experience were all potential risk factors for LBP in middle-aged adults. Middle-aged adults in Indonesia should be aware of LBP and avoid disabilities by identifying risk factors that may worsen LBP in the future.

Objectives: This study evaluated the effect of serum calcium, parathyroid hormone (PTH), vitamin D, and uric acid levels on pulp stone formation. Materials and Methods: Patients who were admitted to the Muğla Sıtkı Koçman University, Faculty of Dentistry, Department of Oral and Maxillofacial Radiology for dental complaints were registered. Among these patients, individuals who had routine biochemical tests at the same period in the Outpatient Clinics of Muğla Sıtkı Koçman University Training and Research Hospital were included in the study. The patients with at least 1 pulp stone on panoramic radiographs recorded as the "pulp stone group" while patients without any pulp stones were the "control group". Demographic data and serum levels of calcium, PTH, vitamin D, and uric acid were retrospectively evaluated in both groups. Student t-test or Mann-Whitney U test was used to evaluate the differences between the groups. Results: Among 151 patients, dental pulp stone was detected in 53.6% of patients, and 82.7% of these patients were female. Female sex and pulp stone formation were significantly associated (p = 0.001). The mean age of the pulp stone group was 43.9, while it was 39.9 in the control group, without any significant correlation between age and pulp stone (p > 0.05). Similarly, there were no significant differences in serum levels of PTH, vitamin D, uric acid and calcium between groups (p > 0.05). Conclusions: According to the present study, the effect of dental factors rather than systemic factors should be considered primarily in pulp stone formation.
