The variability of the levels of atmospheric particulate matter PM10 and its composition is assessed in the rural and urban zones of Mexicali during fall and winter 2008-2009, using a low level volume Minivol sampler, with quartz and Teflon filters. During fall the Mexican norm was exceeded (120 μg/m3 in 24 hr) in only two occasions, while in winter it was exceeded twelve times. The predominant component in fall was geological material with 62.5% for the rural zone and 48.5% for the urban one. In winter the geological material was also predominant with 65% for the rural zone and 54.4% for the urban zone. The aim of this work is the interpretation of the variability of the atmospheric PM10 particulate matter at two selected zones (urban and rural of Mexicali) during fall and winter, with emphasis on the chemical composition. The results suggest that the pollution in the urban and rural zones has common sources during winter whereas in fall the pollution has different sources.

Origanum vulgare L. (oregano) and Rosmarinus officinalis L. (rosemary) are vegetal species belonging to the family Lamiaceae, popularly known as oregano and rosemary. Aromatic plants are used in the treatment and prevention of diseases and in the culinary as functional food in the preparation and conservation of foods. In the chemical composition of oregano and rosemary are present bioactive compounds with antimicrobial, antioxidant and flavoring effect. Several reports in the literature have presented the chemical composition and biological activity of the essential oils of oregano and rosemary. However, few studies have been carried out regarding the chemical composition and biological potential of the aqueous and ethanolic extracts of Origanum vulgare L. and Rosmarinus officinalis L. Evidencing a need to investigate the chemical composition and antifungal activity of these extracts. The objective of the study was to evaluate the bioactive compounds and antifungal activity of the aqueous and ethanolic extract of Origanum vulgare

Biological membranes are essential for cell life and hydration. Water provides the driving force for the assembly and stability of many cell components. Here, we study the structural properties of water in a phospholipid membrane. We characterize the local structures, inspecting the intermediate range order （IRO） and adopting a sensitive local order metric recently proposed by Martelli et al. that measures and grades the degree of overlap of the local environment with the structures of perfect ice. Close to the membrane, water acquires a high IRO and changes its dynamical properties; i.e., its translational and rotational degrees of freedom slow in a region that extends over - 1 nm from the membrane interface. Surprisingly, we show that at distances as far as -~ 2.5 mn from the interface, although the bulk-like dynamics are recovered, the IRO of water is still slightly higher than that in the bulk under the same thermodynamic conditions. Therefore, the water-membrane interface has a structural effect at ambient conditions that propagates further than the often-invoked 1-nm length scale. Consequently, this should be considered when analyzing experimental data of water confined by membranes and could help us to understand the role of water in biological systems.
