Plasmodium, Isospora, Toxoplasma, Babesia and Cryptosporidium are parasites which have a significant role in human health. The location in which the protozoon settles in the body, the way that it leaves the host, and the sample which is send from the clinic are the elements of the general methods used in the diagnosis of the ailments caused from protozoan. Classical methods are not adequate for the identification of some protozoon; also, molecular methods have to be used in designating the distinctions between the species. In recent years, one of the molecular methods which has been used frequently in the identification of protozoon is the technique of LAMP. With the aid of the LAMP technique, from which it is possible to obtain reliable outcomes without the contribution of technical skills and professional equipment, in constant temperature it is possible to have a great number of copies from the targeted DNA in a short period. The aim of this collation is to give information about the usage of the technique of LAMP in the identification of the protozoa which are important for human health and the comparison between the technique of LAMP and other molecular methods.

Competing endogenous RNAs (ceRNAs) are RNA transcripts which can communicate with each other by decreasing targeting concentration of micro-RNA (miRNA) with the derepression of other messenger RNAs (mRNAs) having the common miRNA response elements (MREs). Oncocers are ceRNAs taking crucial roles in oncogenic pathways processed in many types of cancer, and this study analyzes oncocer-mediated cross-talk by sponging microRNAs (miRNAs) in these pathways. While doing this, breast, liver, colon, prostate, gastric, lung, endometrium, thyroid and epithelial cancers and melanoma, rhabdomyosarcoma, glioblastoma, acute promyelocytic leukemia, retinoblastoma, and neuroblastoma were analyzed with respect to ceRNA-based carcinogenesis. This study defines, firstly, oncocers in the literature and contains all oncocer-related findings found up to now. Therefore, it will help to increase our comprehension about oncocer-mediated mechanisms. Via this study, a novel perspective would be produced to make clear cancer mechanisms and suggest novel approaches to regulate ceRNA networks via miRNA competition for cancer therapeutics.

The aim of this meta-analysis study was to investigate the effect of internet use on the components of well-being. Life satisfaction, well-being and self-esteem were evaluated as markers of well-being and their interaction with internet use was assessed. Publications in the literature were collated (N = 281) by investigating articles related to the topic. In light of criteria determined by the researcher, 23 studies were included in the analysis. This study comprised a sample group of 21,054 individuals. The mean age of the sample group was calculated as 20.32 years. According to the results of the analysis using the random effect model, internet use has a significant effect on well-being at low levels (k = 28, r = −0.18, p < 0.001). The components of well-being were used as moderator variables. Results of moderator analysis showed that the well-being components were not significant moderator variables of the effect of internet use on well-being (Qb = 1.34, df = 2, p > 0.05). According to the results of the research, internet use is an effective variable on well-being. The results are discussed in light of the literature. © 2016 Elsevier Ltd

Basic biological information of the puffer fish Lagocephalus sceleratus is presented based on a 2 year study. A sample of 656 fish with total lengths ranging from 12.5 to 65 cm was collected from commercial catches and fishing line at the Antalya Bay between December 2008 and January 2010. Males made up 51.3% whereas females 48.7% of the population. The length - weight relationship was given by TW = 0.012 TL 2.979. The Bhattacharya method was used to separate cohorts from a length frequency distribution obtained pooling monthly samplings. The von Bertalanffy growth model was used to fit growth curve to the length frequency data. The von Bertalanffy growth equation were L t=126.11(1-e -0.099(t+1.4349)). The spawning takes place during early summer. Relative fecundity was 780.8±171.8 eggs g -1the total body weight and average egg size was 640 μm in diameter in June. Analysis of the diet composition showed that the fish is carnivorous and crustaceans are the major food items for L. sceleratus. © Published by Central Fisheries Research Institute (CFRI) Trabzon, Turkey in cooperation with Japan International Cooperation Agency (JICA), Japan.

Civil and Kacali streams are one of the most important streams of Ordu city. However, there were too much pollution in down parts of these streams due to environmental vastes, coming from sewages and agricultural activities. When water flow decreased in dry seasons, eutrophication was observed following water blooms in these streams. Extreme eutrophications occurred in Civil and Kacali streams at the end of spring and early summer in 2009. Because of excessive algal blooms, dense green masses covered a large portion of the stream surfaces in the study term. In the examination of both the stream, Hydrodictyon reticulatum (Linnaeus) Bory de Saint-Vincent (water net) from the filamentous green algae let to excessive water blooms. This alga is a species that reduces oxygen level and disrupts the appearance in this types of watfers where are stagnant and shallow. Dissolved oxygen was determined as 4.76 mg/L in Civil Stream and 7.23 mg/L Kacali Stream in blooming time. In during eutrophication, sampling was made from the two streams and some physico-chemical and biological properties were examined. Results of analysis were compared with standards of the Turkish Water Pollution Control Regulation (WPCR). Phosphorous which is the important nutrient and causes water bloom was found at high ratio in the stream waters. In terms of these parameters, the streams have water quality at fourth category. It was determined that Civil Stream was much more polluted than Kacali Stream. © Sila Science.

The cross-sectional study was conducted to examine the relationship between sexual function, body mass index and body image among women. 193 women were included in the sampling. The data was collected using questionnaire form, the Female Sexual Function Index (FSFI), and Body Image Scale (BIS). The mean of the total FSFI score was 22.62 (SD 6.54, range 2.00-32.00). The mean of the BIS score was 145.29 (SD 17.73, range 93-200). The mean of the body mass index (BMI) was 24.50 (SD 3.75, range 16.05-35.56). Of the six sexual function parameters, pain (r = 0.044) did not correlate with BIS, while desire (r = 0.351), arousal (r = 0.335), lubrication (r = 0.242), orgasm (r = 0.335), satisfaction (r = 0.339) and FSFI total (r = 0.343), all p < 0.001 did. In according to BMI groups of women were observed significant difference in BIS scores (p = 0.007), but FSFI scores were not (p > 0.05). In conclusion, positive body image of women had a positive effect on their sexual function. Overweight and obese based on BMI among women had a negative effect on woman's body image, but had no effected on woman's sexual function. © 2012 Springer Science+Business Media, LLC.

In this study, the vibration effects of a vortex that occurred in high-head Francis turbines and an alternator are examined. The vortex effect, which directly affects the efficiency and the quality of the energy, was tested at the Darca-1 hydroelectric power plant (HPP) located in Ordu Province, Turkey. Formed by undissolved oxygen in the water, the vortex effect, which is parallel to the alternator load, causes tremendous vibration within the alternator and Francis turbine bearings. This problem, which has a direct negative effect on the alternator capacity, was solved by adding an air-admission system. In doing so, power production was increased by 11.11%, from 44 MW to 49.5 MW. This caused a significant head loss, specifically in the Francis turbines. Vortex optimization was successfully established at the Darca-1 HPP. © Tübi·tak.

Background: The aim of this study was to determine the health beliefs and knowledge about breast self examination (BSE) and the actual BSE habits of female university nursing students. Materials and Methods: The study sample recruited 189 nursing students who agreed to participate in the study. Descriptive statistics, the Mann-Whitney U test, one way ANOVA test, t test and Pearson correlation analysis were used to analyse the data. Results: 83.1% of nursing students had knowledge about breast cancer (BC) and BSE in the study. BSE was practiced by 70.4% of nursing students; 21.8% of them performed BSE regularly. A fear of developing BC was an incentive for 85% of nursing students to practice BSE. The confidence subscale scores in the third and fourth years of students' university education were higher, and the barrier subscale score in these same years was lower than their first years of study. Perception of benefit of nursing students experiencing breast-related discomfort exerted a positive effect. Nursing students with lower perception of barriesr performed BSE regularly. In conclusion, nursing students' years of university study, breast cancer knowledge, history of breast cancer in family, and BSE practice status were factors affecting their health beliefs. Conclusions: These study results indicate the importance of developing education and training programs which educate not only nursing students but all women about breast cancer, its symptoms, the importance of early diagnosis and of regular BSE.

The objective of this study was to compare the biologic and prosthetic outcomes of early- and conventionally-placed implants supporting fixed prostheses. Using inclusion/exclusion criteria, early- and conventionally-placed implant patient groups, rehabilitated with Branemark System implants supporting fixed prostheses for 2 years, were selected from the patient archives. Kaplan-Meier survival estimates, time-dependent marginal bone loss, Plaque Index, peri-implant infection, Bleeding Index scores, and prosthetic complications data of the groups were compared. A total of 212 implants were placed in early-placed (n=42, 101 implants) and conventionally-placed (n=45, 111 implants) patient groups and 5 implants failed during the 2-year follow-up. The 1- and 2-year Kaplan-Meier survival probabilities of early-placed (0.98) and conventionally-placed (0.973) groups were comparable (P=.735). The 6-month to 2-year marginal bone loss in the conventionally-placed group was higher than in the early-placed group (P<.05). There were differences between groups on soft tissue scores between the 2 years of function (P<.05). The frequency of prosthetic complications was very low and comparable in both groups (P=.476). Early- and conventionally-placed implants supporting fixed prostheses showed comparable clinical outcomes during the 2-year follow-up, although the marginal bone loss was higher in the latter group.
