Multiple environmental factors impact non-alcoholic fatty liver disease(NAFLD).While the association with dietary habits and physical activity is broadly characterized(1),the contribution of socioeconomic disparities to these risk factors remains elusive to date(2).A cross-sectional study of the National Health and Nutrition Examination Surveys(NHANES)(3)recently examined a cohort representative of the adult *** for combined effects of socio-demographic and lifestyle patterns on NAFLD risk *** activity,a high-quality diet and higher education,but not income level,were found to reduce the risk of NALFD,irrespective of ethnicity or *** NAFLD is estimated to affect up to a quarter of the global population and particularly become more prevalent in industrialized countries(4),proper characterization of associated population-based risk factors is crucial in optimizing public health and educatory preventive and treatment directives.

Sliding plasma actuators were used to control the flow-induced broadband noise radiating from a bluff body. The structure consisted of a cylinder and a torque link that was installed on the lee side of the cylinder. The objective was to reduce the noise generated during the cylinder wake impinging on the torque link. By manipulating cylinder wake with the externally-imposed body force generated by the plasma actuators, the flow-structure interaction was reduced, leading to an attenuation of the broadband noise up to 3 dB in overall sound pressure level at a free stream speed of 30 m/s.

We explore the hypothesis that a potential explanation for the initiation of motor neuron disease is an unappreciated vulnerability in central nervous system defense,the direct delivery of neurotoxins into motor neurons via peripheral nerve retrograde *** further suggests a mechanism for focal initiation of neuro-degenerative diseases in general,with subsequent spread by network degeneration as suggested by the Frost-Diamond *** propose this vulnerability may be a byproduct of vertebrate evolution in a benign aquatic environment,where external surfaces were not exposed to concentrated neurotoxins.
