Cluster of cases due to Shigella flexneri producing CTX-M-15 in Spain.

The aim of our study was to delineate an outbreak of gastroenteritis caused by Shigella flexneri and affecting sixteen persons between May and June 2014 in Bilbao, Spain. All patients exhibited symptoms after consuming kebab in the same kebab shop.The outbreak is described through the clinical cases, the microbiological and molecular genetic diagnosis, and the epidemiologic investigation.

Diversity-Oriented Synthesis Catalyzed by Diethylaminosulfur-Trifluoride-Preparation of New Antitumor Ecdysteroid Derivatives.

Fluorine represents a privileged building block in pharmaceutical chemistry. Diethylaminosulfur-trifluoride (DAST) is a reagent commonly used for replacement of alcoholic hydroxyl groups with fluorine and is also known to catalyze water elimination and cyclic Beckmann-rearrangement type reactions. In this work we aimed to use DAST for diversity-oriented semisynthetic transformation of natural products bearing multiple hydroxyl groups to prepare new bioactive compounds.

Photocatalytic Crystalline and Amorphous TiO Nanotubes Prepared by Electrospinning and Atomic Layer Deposition.

In this work core/shell composite polymer/TiO nanofibers and from those TiO nanotubes were prepared. First, poly(vinyl alcohol) (PVA) and poly(vinylpyrrolidone) (PVP) fibers were synthetized by electrospinning. They were covered with a 100 nm thick amorphous TiO layer by atomic layer deposition at 50 °C.

[Relationship between arterial stiffness and regular physical activity].

Összefoglaló. A cardiovascularis megbetegedések kialakulását és progresszióját jelentősen befolyásolja az életmód, ezen belül a fizikai aktivitás. A rendszeres testmozgás csökkenti a szív- és érrendszeri kórképek kockázatát, többek között a magas vérnyomásra, a zsíranyagcsere-eltérésekre és az elhízásra gyakorolt kedvező hatásán keresztül, továbbá független tényező a cardiovascularis halálozás szempontjából is.

Natural radioactivity and radiological risks of common building materials used in Semnan Province dwellings, Iran.

Impact assessment of building materials is a focused topic in the field of radioecology. A radiological survey has conducted to monitor radioactivity of most common building materials in Semnan Province, Iran, and assess the radiation risk. Activity concentrations of Ra, Th, and K were measured in 29 samples including nine commonly used building materials that were collected from local suppliers and manufacturers, using a high purity germanium gamma-ray detector.
