BACKGROUND This study was designed to determine the Human papillomavirus (HPV) prevalence and its distribution of genotypes in various regions of Yunnan Province, China. METHOD In this study, participants were recruited during routine gynecologic examination between Oct 2013 and Feb 2015. A total of 17,898 women were recruited. Polymerase chain reaction was used for detecting the HPV positive...

background and aims. fluorosis is defined as a sort of enamel hypocalcification. clinical features of fluorosis vary from thin white lines on the enamel to chalky and opaque enamel. the enamel may be destroyed after tooth eruption. various prevalence rates have been reported in different populations. major contributing factors are temperature, altitude and hygienic trends. the aim of this study...

The mechanisms that determine population structure in highly mobile marine species are poorly understood, but useful towards understanding the evolution of diversity, and essential for effective conservation and management. In this study, we compare putative sperm whale populations located in the Gulf of Mexico, western North Atlantic, Mediterranean Sea and North Sea using mtDNA control region ...

medical x-rays are the largest man-made source of public exposure to ionizing radiation. while the benefits of computed tomography (ct) are well known in accurate diagnosis, those benefits are not risk free. ct is a device with higher patient dose in comparison with other conventional radiation procedures. so it is important to avoid conditions where the amount of radiation used is more than th...

garlic (allium sativum l.) as one of the most valuable industrial and pharmaceutical plants has been studied from many aspects because of its importance. but there is not any sufficient and reliable information about its distribution and classification. so its types are categorized according to traditional, local or geographical names or some visual traits. the most important reason is the ster...

Conservation initiatives to protect and restore valued species and communities in human-dominated landscapes face huge challenges linked to the cost of acquiring habitat. We ask how the sale of forest carbon offsets could reduce land acquisition costs, and how the alternate goals of maximizing α or β-diversity in focal communities could affect the prioritization land parcels over a range of con...

Neustonic microplastic and zooplankton abundance was determined in the North Western Mediterranean Sea during a summer cruise between July 9th and August 6th 2010, with a break between July 22 th and 25th due to a strong wind event. Ninety percent of the 40 stations contained microplastic particles (size 0.3-5mm) of various compositions: e.g., filaments, polystyrene, thin plastic films. An aver...

During 1977-8 we made a detailed study of anaesthetic staffing and work in the North-western RHA to help provide a rational basis for allocating additional posts. We submitted a full report to the RHA and the main findings are summarised in the table. The threefold variation in operations performed shows that more sophisticated data than overall hospital catchment population figures are require...

Sea turtles face threats globally and are protected by national and international laws. Allometry and scaling models greatly aid sea turtle conservation and research, and help to better understand the biology of sea turtles. Scaling, however, may differ between regions and/or life stages. We analyze differences between (i) two different regional subsets and (ii) three different life stage subse...

Three mitochondrial DNA (mtDNA) markers were used to infer the phylogenetic relationships of the morphologically diverse, species rich, and poorly understood western North American aquatic gastropod genus Pyrgulopsis (Hydrobiidae: Nymphophilinae). Sequences were obtained from 62 of 124 currently recognized species of Pyrgulopsis and representatives of four related genera of North American nymph...
