Dental Implants and Orthodontic Mini-Screws in a Patient with Undiagnosed Von Willebrand's Disease: A Case Report.

Dental implants are commonly employed to address edentulism, while orthodontic treatments often incorporate mini-screws to enhance tooth movement and provide stable anchorage. Both procedures are integral to modern dental practice and frequently interact in comprehensive care scenarios. While oral health professionals routinely assess patients' medical histories before procedures, undiagnosed coagulopathies, such as Von Willebrand Disease (VWD), can present significant challenges when invasive procedures are carried out, such as the insertion of implants or mini-implants.

Effect of smectic polymers on cholesteric liquid crystals.

Composite materials made of polymers and liquid crystals have been widely employed in smart windows, optical filters, and bistable displays. However, it is often difficult to decipher the role of the polymer network architecture on the alignment and the texture of liquid crystals. In this study, we use a simple model system where a small amount of polymerizable liquid crystalline monomer is mixed in a liquid crystal that exhibits both a smectic phase and a cholesteric phase with a large helical pitch.

Refining Abdominoplasty: A Novel Technique for Umbilical Reconstruction.

Background: The umbilicus holds significant aesthetic and symbolic importance in abdominal contouring. Its position, shape, and overall appearance are pivotal in determining the success and patient satisfaction after abdominoplasty, although the best way to archive it is discussed. We present our technique with our statistics and complication rate.

Gill regeneration in the mayfly uncovers new molecular pathways in insect regeneration.

The capacity to regenerate lost organs is widespread among animals, and yet the number of species in which regeneration has been experimentally probed using molecular and functional assays is very small. This is also the case for insects, for which we still lack a complete picture of their regeneration mechanisms and the extent of their conservation. Here, we contribute to filling this gap by investigating regeneration in the mayfly .
