Veterinary Dermatology, Volume 34, Issue 6, Page 586-596, December 2023., 2023 Background – In clinical practice, the diagnosis of otitis externa (OE) normally is based on otoscopic examination and cytological findings, followed by empirical treatment with topic drugs. Biofilm‐producing bacteria are frequently present in OE, even if its presence is often underdiagnosed. Hypothesis/Objectives – The primary aim of this study was to

Reproductive aspects and pollination biology in endoparasitic Pilostyles thurberi (Apodanthaceae)
Plant Species Biology, Volume 38, Issue 2, Page 40-53, March 2023., 2023 We studied pollination and reproductive strategies of the endoparasitic plant Pilostyles thurberi. The reproductive strategy, floral rewards, pollination system, and variation of their sexual flower arrangement were recorded. This endoparasite presents differences in reproductive success between different sites. Abstract Biotic pollination is typically

Rose petal effect: A subtle combination of nano‐scale roughness and chemical variability
Nano Select, Volume 3, Issue 5, Page 977-989, May 2022., 2022 The high contact angle and major drop adhesion of water drops to natural rose petal surfaces is a result of their fractal‐like roughness and nano‐scale chemical heterogeneity as shown here using atomic force microscopy. The combination of topographic and chemical variability is described by a single wetting parameter which can be applied to any sort of

International Journal of Chemical Engineering, Volume 2018, Issue 1, 2018., 2018 The modulation in the synthesis parameters of layered manganese oxides allowed us to produce materials with different AC conductivities. These conductivities were correlated with the catalytic performance of the materials in the decomposition of methylene blue, as a model of electron transfer reactions.
