Obstructed Hemivagina and Ipsilateral Renal Anomaly (OHVIRA) Syndrome: A Diagnosis in the First Year of Life.

Obstructed hemivagina and ipsilateral renal anomaly (OHVIRA) is a rare congenital anomaly that affects females. Although it is possible to diagnose in early life, most cases are usually diagnosed in adolescence or adulthood. This delay in diagnosis can cause a variety of complications, some associated with infertility or renal failure.

High-alignment-accuracy transfer printing of passive silicon waveguide structures.

We demonstrate the transfer printing of passive silicon devices on a silicon-on-insulator target waveguide wafer. Adiabatic taper structures and directional coupler structures were designed for 1310 nm and 1600 nm wavelength coupling tolerant for ± 1 µm misalignment. The release of silicon devices from the silicon substrate was realized by underetching the buried oxide layer while protecting the back-end stack.

[Immunology of dental caries].

Dental carie is the most common infectious disease in humans. In the past decades, it has been described as a multifactorial condition, where diet and the immune response are main factors for the establishment of the disease. The authors approach the formation of the bacterian biofilm, the host's immune response, according to its maturation and deficiencies, and the current research to find a preventive intervention for this disease.

(Z)-Ethyl 2-hydroxy-imino-2-(4-nitro-benz-yl)ethanoate.

The title mol-ecule, C(11)H(10)N(2)O(6), has a Z conformation about the C=N bond of the oxime unit. There are significant twists from planarity throughout the mol-ecule, the most significant being between the hydroxy-imino and ester groups which are effectively orthogonal with an N-C-C-O(carbon-yl) torsion angle of 91.4 (2)°.
