al monogamy4 and covert sex outside the main relationship. Delayed marriage and high divorce rates mean that growing numbers of individuals experience multiple sexual partners in a lifetime, and this greatly increases their exposure to infection. Furthermore, National Health and Social Life Survey data show that around 25% of men and 10% of women report extramarital or extracohabitational affai...

Rodent animal models have been widely used for studying neurologic and toxicological events associated with cocaine abuse. It is known that the mouse is more susceptible to cocaine-induced hepatotoxicity (CIH) than the rat. However, the causes behind this species-dependent sensitivity to cocaine have not been elucidated. In this study, cocaine metabolism in the mouse and rat was characterized t...

The chemical and mechanical properties of extracellular matrices (ECMs) modulate diverse aspects of cellular fates; however, how regional heterogeneity in ECM composition regulates developmental programs is not well understood. We discovered that fibronectin 1 (Fn1) is expressed in strikingly non-uniform patterns during mouse development, suggesting that regionalized synthesis of the ECM plays ...

ZnO nanoparticles (NPs) are engineered nanoparticles used in many commercial products inclusive of cosmetics, paints, textiles, and sanitary products. ZnO NPs are potent in protecting the skin against UV radiation so, they are used as ingredients in sunscreen and moisturizing creams/lotions and hence the study of their toxicity is essential. On the one hand, nanoparticles, due to their small si...

A study was conducted to determine the prevalence of intestinal parasites in children from eight schools located in Phuttamonthon District, Nakhon Prathom Province during November 2004 to December 2004. Stool samples were collected from 1920 students; age range from 7 to 12 years old, and examined for intestinal parasites by using formalin-ethyl acetate concentration technique. Of these subject...

As a former district nurse and latterly a tissue viability clinical nurse specialist (CNS), I have always been interested in patients with unmet psychosocial needs relating to chronic venous leg ulceration (Brown, 2003). The high recurrence rates of venous leg ulcers is well documented (Mayberry et al, 1991; Moffatt and Franks, 1995). It therefore always seemed a futile exercise to heal leg ulc...

در این کار پژوهشی، نمونه‌های هیدروکسی اپتایت آلاییده با ناخالصی‌های سریم، گادولونیم و ترکیبی از دو ناخالصی به روش هیدروترمال سنتز شدند. منظور بررسی فازهای بلوری تشکیل یافته هرکدام شده، کد MAUD که یک نرم‌افزار برای تجزیه تحلیل ساختار ماده استفاده پراش بر اساس ریتولد است، شد. پاسخ دزیمتری ترمولومینسانس نمونه‌ها مورد قرار گرفت یافته‌ها نشان داد نمونه‌ ترکیبی، سطح میانی است. مشخص شد افزودن سریم می‌...

I treat three related subjects: virtual-worlds research-the construction of real-time 3-D illusions by computer graphics; some observations about interfaces to virtual worlds; and the coming application of virtual-worlds techniques to the enhancement of scientific computing. We need to design generalized interfaces for visualizing, exploring, and steering scientific computations. Our interfaces...

In this assessment we summarise advances in our knowledge of how UV-B radiation (280–315 nm), together with other climate change factors, influence terrestrial organisms and ecosystems. We identify key uncertainties and knowledge gaps that limit our ability to fully evaluate the interactive effects of ozone depletion and climate change on these systems. We also evaluate the biological consequen...

Gerade erst wurde das Urlaubsgeld gestrichen und das Weihnachtsgeld gekürzt, kurz darauf wird die Arbeitszeit verlängert – ohne Lohnausgleich. Kein Wunder, dass die Angestellten im Öffentlichen Dienst aufgebracht sind. Als spontane Reaktion auf den Beschluss der Bundesländer zur Arbeitszeitverlängerung hatte es bereits Ende März erste Proteste gegeben. Nun liegen sogar Warnstreiks in der Luft –...
