Hydrocarbon degrading microorganisms play a major role in the environment.. The purpose of the present study was to enumerate of Aeromanas sp from oil contaminated soil and to study degrading capacity, emulcification activity and production of biosurfactant. The hydrocarbon substrate specificity test shown that diesel is also one of the best substrate for growth and emulsification of biosurfactant by Aeromonas. Among 6 strains of Aeromonas, frist strain(A1) shows maximum degradation rate at end of 168 hrs upto19.37% followed by other strains, about 75% of diesel was degraded by Aromonas over a period of 7days. Emulsification upto 75% by A1 followed by A2(63.75%) ,A3(57.5%), Biosurfactant production by A1 strain 0.064g/1 followed by other strains it represents a new type of biosurfactant with strong emulsifying ability.
Water quality is widely discussed owing to its significance in public health due to the inability to access clean water. Waterborne diseases account for the presence of pathogens like Escherichia coli (E. coli) in drinking water in the environmental community. Owing to the rapid increase of such bacterial microorganisms, a cost-effective sensor setup has been developed. Herein, we demonstrate the amine-functionalized graphene oxide (fGO) based 2D nanomaterial used to graft E. coli on its surface. The comparative analysis of the deposition of nanosheets on the glass substrate and PDMS was executed. The impedance variations of GO-based nanosensor at various concentrations of E. coli were performed and their potential difference was recorded. It was observed that the impedance changes inversely with the bacterial concentrations and was fed to the Arduino microcontroller. The experimental setup was standardized for the range of 0.01 Hz to 100 kHz. The obtained analog data was programmed with a microcontroller and the bacterial concentration in colony-forming units was displayed. The real-time analysis showsthe low-level detection of E. coli in aquatic environments. Experiments were conducted using the developed nanosensor to test the efficiency in complex water matrices and whose behavior changes with various physical, chemical, and environmental factors.
Aripiprazole is an antipsychotic with partial agonist activity at the dopamine D2 receptor which may lead to compulsive behaviors including hypersexuality. The case presented is of a 24-year-old male with schizophrenia who developed hypersexuality symptoms after initiation of aripiprazole. Cessation of the aripiprazole led to a reduction in hypersexual behaviors. Clinicians should be aware of compulsive behaviors including hypersexuality with aripiprazole use and consider discontinuation of aripiprazole treatment in patients suffering from hypersexuality.
Neuroimaging has been dramatically advanced by diffusion-weighted and diffusion-tensor imaging (DWI/DTI). Moreover, DWI/DTI permits the examination of the brain's microarchitecture. A thorough understanding of the fundamentals is essential to better understanding pathological presences and avoiding misinterpretation of typical DWI/DTI abnormalities. Diffusion-weighted imaging (DWI) is based on the measurement of the thermal Brownian motion of water molecules, and Diffusion tensor imaging (DTI) is an MRI technique that calculates the axonal arrangement of the brain through anisotropic diffusion. FA, AD, RD, and MD maps are used to study the biological signature of white matter in diffusion MRI studies of brain aging, neurodevelopment, and neurologic injuries. These maps are normally expensive on the market because they are generated separately. Using the DIPY library, we will generate FA, AD, RD, and MD maps to make this process more costeffective.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
