There was no significant change in anterior segment parameters from 1 week to 3 months in the 1-piece group; however, the 3-piece group had statistically significant decreases in ACD, ACA, and ACV. Refraction remained stable throughout the follow-up in the 1-piece group but showed a significant myopic shift from 1 week to 3 months in the 3-piece group.\n\nCONCLUSIONS: After phacoemulsification, the 1-piece acrylic foldable IOL showed little axial movement and provided stable

refraction throughout the follow-up. The 3-piece IOL had significant forward movement and led to a myopic shift within 3 months postoperatively. Results indicate that Metabolism inhibitor spectacles can be prescribed earlier in eyes with a 1-piece IOL.”
“The effect of Mach number on transonic flow past a circular cylinder is investigated numerically for the free-stream Mach number M (az) from 0.85 to 0.98 and the Reynolds number 2×10(5) based on the diameter of the cylinder. The work provides an insight into several salient features, including unsteady and quasi-steady flow state, formation of local supersonic zone, and evolution of turbulent shear layer. Results show that there exist two flow states dependent of a critical Mach number M (cr) around 0.9. One is an unsteady flow state characterized

by moving shock waves interacting with the turbulent flow in the near region of the cylinder for M (az)< M (cr), and the other is a quasi-steady flow state with nearly stationary shock waves formed in the near wake for M (az)> M (cr), suppressing vortex shedding from the cylinder. Some Daporinad purchase flow behaviors in the unsteady and quasi-steady flow states are revealed. From time evolution of flow structures, local supersonic zones are identified in the wake and generated by two typical GNS-1480 processes, i.e. reverse flow behind the cylinder and shed vortices in the near wake. The convective Mach number M (c) of turbulent shear layers shed from

the cylinder is identified nearly as M (c)< 1 in the unsteady flow regime and M (c)> 1 in the quasi-steady flow regime, resulting in different evolutions of the shear layers.”
“Purpose of review Acute otitis media occurs as a complication of viral upper respiratory tract infection. Bacterial otopathogens and respiratory viruses interact and play important roles in acute otitis media development. A better understanding of viral and bacterial interactions may lead to innovative ways to lessen the burden of this common childhood disease. Recent findings There has been increasing evidence that acute otitis media occurs during upper respiratory infection, even in the absence of nasopharyngeal bacterial colonization. Among the types of viruses associated with acute otitis media, respiratory syncytial virus continues to be the most commonly detected.
