The handedness of gastropods is genetically determined, but the molecular nature of the gene responsible and the associated mechanisms remain unknown. In order to characterize the chiromorphogenesis pathway starting from the gene to the left-right asymmetric body plan, we have closely analyzed the cytoskeletal dynamics of the Physa (P.) acuta embryo, a fresh water non-dimorphic sinistral snail,...

La agriculturización es un causante de transformación en los territorios. El actual modelo agricultura predominante, basado la aplicación plagui- cidas para mantener el cultivo saludable y sin competencia, no solo afecta a especie objetivo sino también aquellas blanco, impactando biodiversidad local funcionamiento ecosistemas. del presente estudio fue analizar cambios usos suelo Cuenca Alta Arr...

Although the Brdy Protected Landscape Area is located not far from Prague on border between central and western Bohemia, there was very little published unpublished data its aquatic malacofauna. For this reason, a more detailed survey of molluscs carried out in 2020–2022. Altogether with previous data, 27 species were found at 108 studied sites, including springs, small streams, fishponds, pool...

conclusions the streptomyces sp. suk 25 culturing was optimized using thronton media, at ph 7 and aeration of 140 rpm. further isolation and identification of bioactive compounds will develop anti-mrsa therapeutics. materials and methods disc diffusion and minimum inhibitory concentration (mic) assay were used to determine the antibacterial activity of streptomyces sp. isolates. optimization of...

antimicrobial activity of different culture extract of oudemansiella sp grown on liquid medium (mygp) were tested. different fungi (c. albicans, c. lipolytica, saccharomyces cervisiea, cladosporium herbarum, and aspergillus niger) and bacteria (microccocus luteus, e. coli, staphylococcus aureus, and staphylococcus epidermidis) were used as test organisms. various antimicrobial assay methods inc...
